There are more than 30 people in Zhao Family’s corn peeling workshop. They heard that they were going to play, and they all immediately stopped their work and prepared the corn cob very cooperatively.

In order to ensure the fairness and justice of the game, all the corn piles must be 200 corn cobs, one can not be more than one, not less, which requires them to repeatedly count, and finally by Zhao Xiaoguan and Li An ’s little officials Once again, to ensure that it is indeed 200 corn cobs.

All the people participating in the competition are arranged in neat 3 rows, each row has about 200 people, each person has a bench, 3 corn cobs, and there are also their own tools, of which 1 people are in front of Hand shake corn threshing tools, the rest are very simple grooving knife.

These workers are skilled workers who have worked for more than 3 months. Although the level is slightly different, the gap is not very large. As long as you work hard, the difference is estimated to be very limited.

After everything was ready, Xiao Xiao’s housekeeper came to Li An and said, “Minister Li, they are all ready to start the game.”

Li An looked at the many craftsmen and said, “You guys, the game is about to start. You all person must try your best. No matter what tool you use, you must not be lazy. Must take your highest speed. Well, listen to my orders, the game is now starting, let ’s do it. “

More than 30 people heard the order and immediately started to peel corn. This is a good opportunity to show their performance and a great opportunity to reflect their personal value. How can they not try their best?

The game has just started, and the gap can be seen at a glance. When using a common tool to peel a corn cob, the hand tool was used to peel 5 or 6 consecutively. The gap is too obvious, which makes it stand to watch Li An and the others of the game all smiled satisfactorily.

How can Li An be dissatisfied with such a good result? The structure of this tool is very simple and has almost no technical content. For many ordinary blacksmiths, it is not difficult to build this tool, and it will not cost too much. Cost, which has a great effect on the popularization of this tool. .

The cost of the tool is cheap, but the effect is very obvious. Such an invention is undoubtedly the most successful. No invention is better than this and can satisfy Li An.

“The effect is really obvious. With such a tool, the speed of peeling corn has increased so much. If everyone uses such a machine, then I really dare not think about it! I dare to accept big business in the future. , The owner understood will be very happy. “

Butler Zhao Xiao said very excitedly.

“But such tools are not for your family to use, all corn peeling workshops will use such machines in the future.”

Said an official.

“That is all the owners are happy, all happy, hahaha!”

Butler Zhao Xiao said happily.

Although each man participating in the competition is surrounded by 200 corn cobs, due to the fast hand-cranking speed, most corn cobs are destined to have no chance of being peeled. The setting of so many numbers is just to show that the hand-cranking tools are normal. The superiority of the hand peeling method, only a considerable number, can reflect the great role of this tool.

After watching the full corn cob stuffed into the hand-cranking tool, it quickly turned into a bare corn cob, and even the working man couldn’t laugh with a smile. This way of working is too comfortable. It’s much more comfortable to rub your hands, and the efficiency is much higher, which makes them very happy.

However, this tool does not fundamentally change their situation. After they use the tool, it is always cool, but after this tool is popularized, because all threshing workshops will use it, this way, the corn kernels The selling price will definitely be affected, so the processing fee of the same weight will be reduced. The amount of work they used to peel corn kernels by hand one day will be directly increased many times. The original salary of 5 times is the original salary. Sure, of course, the physical strength and time they consume are not at all too different, just change a tool to work.

People are always interested in new things, especially those that bring benefits to themselves, and they are even more interested, those who work are interested, those who manage are interested, those who are onlookers are also interested If you let the owner of this workshop understood, it would be even happier.

The 200 corn cobs seem to be many, but in fact there are really not many at all. For the hand-cranked corn threshing tool, there are only 200 corn cobs. This is just a small dish, which can be dried quickly.

No, Li An just left the 2-Layer building and went to other places in the workshop. When he came back, the three hand tools had processed more than half of the corn on the cob. Those who used the original method, Only a few parts were processed, and the gap was extremely obvious.

“The effect is coming out. All of our hand-cranked tools are almost finished. Only a small part is processed using the original method. That’s right, right. It’s about to end soon, haha!”

Li An said with great pleasure.

The housekeeper Zhao Xiao was not idle either. He crouched down and carefully inspected the corn kernels processed by the hand-cranked tool to see what the effect was.

“Minister Li, the effect of this hand tool is really good. The corn kernels are not damaged at all. This machine can be used and it is very easy to use.”

Butler Zhao Xiao said happily.

Soon, the corn cobs in front of one of the hand-cranked machines were completely processed, which took a very short time, which made Li An very satisfied.

“Stop, everyone stops.”

Li An spoke directly ordered.

“Stop, stop.”

Zhao Xiao’s housekeeper ordered the men to stop the game.

Li An slightly nodded signaled that the little officials and the housekeeper Zhao Xiaohu quickly ordered to count the remaining corn on the cob, and figured out how much each person processed. Only half of them were processed.

It takes a little time to count the corn cobs, but if there are many people, it will not take much time to count them.

“Minister Li, the results have come out. In addition to the first hand-cranked corn threshing tool for processing 200 corn cobs, the remaining 2 sets process 100 95 and 100 89 respectively, while the remaining manual peeling corn, at most one Only 45 corn cobs were processed, and the least one processed only 34 corn cobs, the difference is about 5 times. “

A small official reported the situation.

“The gap is five times the average. As expected by This Official, this gap is already very good. One person can cover 5 people for use. In this way, 5% of the labor force can be saved, which can greatly alleviate the shortage of labor force in Beijing. . “

Li An said with great satisfaction.

Of course, Li An is very satisfied with the efficiency of 5 times. This efficiency is not a little bit. This is a big improvement. With this powerful tool, the efficiency of corn threshing can already be greatly improved. This It makes the following corn threshing machine research less urgent, and as a result, Li An can focus more time on other machines. This hand-cranked corn threshing tool can completely hold for a long time. After the popularity of this hand-cranked tool, it is not too late to launch a corn-peeling machine.

“Minister Li said that such a gadget is really ingenious, not only solves the problem of peeling corn kernels, but also is not expensive. The ordinary blacksmith can know how to build it with a little thought, but, Or our blacksmith builds better, we have specialized machines, and the tools produced produce the best results. “

Said the little official.

Li An laughed, said: “I see that, these parts are very important. If they are not well-made, it will affect the use efficiency of the hand corn thresher. Therefore, we can mass produce these parts, and then If you sell it, the rest of the parts will not be so particular. Let them find a solution. This official believes that these ordinary craftsmen can solve it. “

For the production of hand-cranked corn threshing tools, Li An feels that the lower the cost, the better. Large-scale production of core components can reduce the cost of individual components. For the less important parts, it is sufficient to use some metal scrap, even wood. There is no need to waste limited resources, so non-core components are not produced.

After some exchanges, Li An said, “Leave one of the three tools and give them to you, and the remaining two will be taken away, ready to be promoted. In the future, the whole corn threshing workshop in Beijing will use this Hand tool. “

“Many thanks Minister Li, many thanks Minister Li.”

Zhao Family’s little housekeeper is very excited to thank him. He has no reason to be unhappy because he can get such a good tool. Moreover, he can brag about it in front of his family and take credit for getting this useful tool. On yourself.

After returning to the Research & Development Center, Li An handed over the task of promoting the hand-cranked corn thresher to a young man who took full responsibility for this matter, and Li An began to draw the drawings of the glove knitting machine. The difficulty of this machine Not too big, but too trivial, there are too many parts inside, in order to ensure a certain reliability, you must be careful when designing, you must consider the parts that are easily damaged, and carry out a certain degree of these parts optimization.

Textile machines such as glove knitting are different from machines that manufacture parts. The biggest problem of this machine is that it is easy to break the thread. Imagine whether the fragile cotton thread will break when it passes through the metal machine due to friction with the metal machine. What about it? Or is it not good for sanding? If the cotton thread is cut by the machine when passing through the machine, it is impossible to weave gloves. This is very critical. The smaller the probability of thread breaking, the better, and the smaller the thread breaking rate, the more popular the textile machine.

Although the cause of the cotton thread breakage may not necessarily be the cause of the machine, it may also be a problem of the quality of the cotton thread itself, but a good textile machine, even if the quality of the cotton thread is not good enough, there will not be too many thread breakage problems, and Textile machines with poor quality, even if the quality of the cotton thread is very good, will often cause thread breakage problems.

The workers who have done textile work are very clear in their hearts, how annoying this thread break is, especially when there is a large area of ​​thread break, it is very terrible, and it can exhaust the workers who work.

Although textile is a light industry, in fact, it is not light for working workers, especially in factories with poor machines. These garbage machines often cause lines to be broken, and then workers are busy. Yes, one is broken, one is connected, 100 is broken, 100 is connected, of course, 10000 is broken, and of course 10000, and each wire is not so easy to connect. In the case of many disconnections , Can really annoy people, even have to work overtime, otherwise it is really impossible to complete such a heavy task.

Because of the heavy workload in the textile industry, there is a lot of overtime work in this industry. It is simply commonplace. Overtime work is not unusual every month. Without such measures, it is impossible to complete the established work tasks. If you increase manpower, The operating cost of the factory has increased greatly. For the workshop Boss, whose interests are more important than life, this is obviously intolerable, so we can only work overtime.

Li An worked in a textile factory in the past life, and it is still a different textile factory. Due to the difference in machine level, the degree of fatigue in different factories is different. A better female worker is responsible for 20 machines, while a poorer female worker can only Responsible for ten units, and, too busy to deal with, this is obviously the gap of the machine level.

Good machines have fewer chances of wire breakage, and bad machines will frequently cause thread breakage, which greatly increases the workload of female workers. The machines that one person can take responsibility are naturally limited, while foreign advanced machines, Even a female worker can be responsible for the level of 100 machines. This gap is not generally small. This is the gap caused by the machine level.

When designing a glove knitting machine, Li An should naturally put control disconnection at the highest priority, because control disconnection is the most important and can control the probability of disconnection, which has a great effect on the working efficiency of this machine. Great effect.

There are only a few reasons for the thread breakage. One is that the cotton thread is not strong enough to be easily broken during the pulling process of the machine, and the vibration of the machine is too large, causing the line to be broken. Machine parts that are in direct contact are also critical. If these small parts are too sharp, it is also easy to cut the cotton thread. Therefore, when designing these parts, must consider the problem of friction. Must avoid stiff diamonds. It is extremely critical that all machine parts that have direct contact with cotton threads are smooth and have no rhombuses.
