Chapter 900 Sewing Machine

Shen Kuo was about to put the second gummy with citric acid in his hand when he suddenly saw the guinea pig in the cage on the side: "You just ...... What do you mean? What do you mean then it's no problem? ”

"Don't worry about the details." Su You said to Shen Kuo: "This is a new industry for you to find in Meizhou!" Just selling rock candy and white sugar is a panic, and you can make a lot of money by selling this, understand?! ”

Shen Kuo was immediately brought to the rhythm: "That's right! These things are all in Meizhou! This kind of crystal luscious candy is not difficult to make, and it is the most suitable big industry in Meizhou! ”

After speaking, he shook his head again: "It's too dark, you are equivalent to mixing water into sugar, and you can sell it more expensive than sugar!" ”

Shi Wei came in, saw the crystal gummies wrapped in frosting in the copper basin, tasted one, and said with a smile: "It's beautiful and delicious, the children will definitely like it, I'll take it to the lifting warehouse in a while." ”

Su You said: "This is just an experiment, I will go to the workshop to find a carpenter to make some small wooden molds in a while, and let Zhang Daochang turn the ground tyre latex into a plastic mold to shape the sugar cubes, which is really beautiful." ”

Shen Kuo was anxious: "Then what are you waiting for, let's leave now." ”

There are a lot of scraps in the corners of the woodworking workshop, Su You turned out a board, drew some hearts, five-pointed stars, rabbits, turtles, dogs, kittens, lions, etc., and asked the carpenter to use a wire saw to see it down, polish it smooth and stick it to another plank, add a frame to make an inverted mold frame, and send it to Zhang Daochang together.

Shen Kuo saw that Zhang Daochang took a white slurry and added some ingredient powder, mixed it thoroughly, poured it into the mold frame, and then poured out the excess slurry, and after repeating it several times, the mold covered with a thick layer of slurry was sent into a glass box, and a kind of sulfur-smelling incense was put into the box.

The additives of dibutin gum are also a huge category, Zhang Daochang has been groping for more than 20 years and has found a lot of useful things.

Shen Kuo is also a curious baby, pulling Zhang Daochang to ask this and that, the day is not over yet, Zhang Daochang took out the wooden mold frame from the box, Shen Kuo found that the slurry that had just been poured in it had become an elastic solid.

Zhang Daochang peeled it off the wooden mold frame: "It's done." ”

Shen Kuoxi said: "I'll try." ”

After making several more plastic molds, Shen Kuo smiled and said: "This thing is good, what else can you do besides breeding and making sugar?" ”

Su You raised his foot: "Now it's a waterproof sole, a water pipe gasket, in the future, or it can be used as a wheel." ”

After speaking, he said: "But it's too early to say that, and the ground lion is still in the stage of promoting planting." ”

Shen Kuo said: "If you want to set up a candy factory, you need at least 100 templates, Zhang Daochang, please ask you to be old." ”

Zhang Daochang smiled: "If it weren't for Mingrun, I wouldn't have thought of so many uses myself, how could this brain grow ......"

Su You said: "Let's go back as soon as the things are done, the second season of rice will be harvested, and the third season will be planted again." By the way, there's another thing I brought you for you, which you can use to produce canvas there. ”

Take Shen Kuo to the mechanical workshop, there is a relatively small machine here, the whole base is Shen Kuo's familiar foot drive equipment, but the top is no longer a jade mill, nor is it a porcelain turntable, but a cast iron guy, on one side is a flywheel, and on the other side is a needle.

It's a sewing machine.

The production technology of the sewing machine is not difficult, and there is no problem at the current level of Meishan Seiko, and this machine is difficult to design the coil stitching system.

The method of coil stitching is very different from ordinary hand sewing.

In the simplest form of hand stitching, the sewer ties a thread in the small eye at the end of the needle, and then threads the needle thread completely through the two pieces of fabric, from one side to the other, and back again.

In this way, the needle moves the threads in and out of the fabric and sews them together.

Although this is very simple by hand, it is extremely difficult to pull with a machine.

The machine releases the needle on one side of the fabric and then grabs it again on the other side at once.

Then, it needs to pull all the loose threads out of the fabric, reverse the direction of the needle, and repeat all the steps in the opposite direction.

This process is simply too complicated for a simple machine.

Su You didn't know the specific principle of the sewing machine, what he knew was probably that the sewing machine had a tooth press, and then the needle nostrils were in the direction of the needle tip, and the needle was driven by the machine to move up and down.

According to Su You's recollections, the craftsmen of Meishan made chain stitching machines, but there is a disadvantage of chain stitching, that is, although it can be sewn very quickly, it is not particularly strong, and if the knot at the end of the thread is loosened, it will cause the entire sewing thread to loosen.

There was no way, Su You had no choice but to ask Sitong Trading to list a reward, five hundred yuan, to reward those who could solve this problem.

In the end, this problem was enshrined by the Sitong Merchant Needle, and the blue-eyed Qiu Niang was solved.

After Qiu Niang brought the woolen knitting method to the Great Song Dynasty, she also became a little rich woman by opening a workshop for knitting sweaters, cotton socks, and gloves.

The little rich woman arranged herself clearly, asked Shi Wei, and found an orphan from the research institute to be her husband.

There is no mother-in-law who discriminates against blood, and the young couple lives a beautiful life.

The researcher undertook the research project of sewing machine coil suturing, and stayed up for many nights, and was ridiculed fiercely after being discovered by Qiu Niang.

What kind of coil suture system deliberately said that such a simple thing stumped all of you scholars?

Let me tell you that this needle is similar to the crochet we use, pulling a thread on the other side of the fabric as a substitute for the sweater needle, and then designing a steel ring to rotate instead of human fingers, so what kind of system is this so-called, not the same as the initial action of our women's crochet?

So the problem is solved, the needle pulls out a coil through the fabric, the rotating hook grasps the coil with a crochet needle, and through the rotation of the hook, the coil is pulled into the new loop formed by the reciprocating motion of the needle, and the sewing is completed.

This kind of stitching is much stronger than chain stitching, and fully meets the needs of making canvas, gun clothing, and sacks.

The notched ring of this key part, which is used to replace the small part of the human finger, is named the hook.

The reward of 500 yuan, which took so long, and the problem that could not be solved was easily solved by a girl who can make sweaters!

Qiu Niang is not short of these five hundred, but it is quite a happy thing to be able to help her husband earn a medal.

Su You has repeatedly told this case at the Institute of Science and Technology.

Look! What does it mean to be attentive and knowledgeable? What is the importance of multidisciplinary linkage? This is a living case!

With the breakthrough of the rotary hook, other sewing machines for special purposes were soon invented.

In addition to this, there are also sewing machines, so that the production of leather goods has also entered the era of sewing machines.

Leather goods have entered the stage of mechanical sewing from manual work, which can directly improve the military strength of the Great Song Dynasty.

Many of the equipment of horses and armies can be replaced with rivets for sewing, and the production of leather shoes can be greatly increased.

Shen Kuo was amazed by the ingenuity of the design of the rotary hook, a key component of the sewing machine, and directly ordered 20 large and small sewing machines and sewing machines from Shi Lian.

Just when the two were discussing the recent mechanical achievements of the Polytechnic Institute, Sun Neng hurriedly ran over: "University scholar, there is a fight in Zhancheng!" Master Wang asked you to go to the shogunate to discuss! ”

Su You said to Shen Kuo: "Let's go, Meizhou is also adjacent to Zhancheng, and Zhenla's reaction is also among the concerns, and you also have your share." ”

The three of them rushed to Ning Haijun, and all the bigwigs were already waiting in the White Tiger Hall.

Su You strode in front of the military map: "What is the situation now?" ”

Wang Shao took the baton: "I just received news from Wang Zhen and Jiuzhou City, and the 30,000 troops of Heli entered the Sanzhou region on the grounds that Dili, Ma Ling, and Buzheng did not obey the king's orders and killed the officials he sent. ”

"Lüdra fled to the border of Jiaozhi and begged the Great Song Dynasty to intervene."

"The local heroes Zhang Lingcong, Liu Feng, and Huang Mu organized the clansmen, Yi Yong, and the name was 'Fengyan Army', saying that they wanted to obey Huode and follow the Great Song Dynasty, and they were unwilling to be the ministers of Lüdra and Heli anymore."

Su You nodded: "What is Wang Zhen's attitude?" ”

Wang Shao said: "Ha Li asked to borrow the city from Wang Zhen as a place for the elephant army to be stationed, and at the same time asked Wang Zhen to provide grain and grass, and the people. ”

Su You said with a smile: "It's a good calculation, why doesn't he want Wang Zhen to send troops to help?" ”

Wang Shao also smiled, this situation had been planned by the two for a long time, but they didn't know that He Li couldn't hold it back so much, and he launched it so quickly: "Worried that Han Li would be destroyed by false means, Wang Zhen asked the Great Song Dynasty to send reinforcements." He was willing to open up the borders of the old state and the Great Song Dynasty. ”
