Before time travel, although Li Zhi had not taken over an industrial design job in the textile industry, as an industrial designer with basic skills, he also understood the structure of textile machinery and had a very clear understanding of the structure of the shuttle. Where should springs be installed and how should guide rails be arranged?
, Li Zhi all knows.
On this day, Li Zhi spread out a piece of rice paper on the table, put some ink in the pen and inkstone with a fine brush, and began to draw the design drawings of various parts of the shuttle. Two quarters of an hour later, Li Zhi had completed five drawings.
A drawing.
Seeing Li Zhi drawing a picture with a pen, Zheng came over puzzled and asked: "Zhi'er, what are you drawing?"
"Mom, what I drew is a new type of loom, which is several times faster than the loom you use."
Zheng said in surprise: "There is such a loom? Impossible! Then haven't all my weaving been in vain for decades?" However, the success of the soap made Zheng trust Li Zhi's new idea.
I couldn't help but ask: "Zhi'er, where did you learn this kind of loom?"
"An old Taoist priest taught me!"
"That Taoist priest again? Why did he teach you so many good things?"
Li Zhi smiled and did not answer his mother's question. He took the blueprint and went to the blacksmith shop to find someone to make the shuttle.
When going to the blacksmith shop, Li Zhi was cautious and handed different parts to several different blacksmiths to prevent a single blacksmith from knowing the structure of the entire shuttle and replicating Li Zhi's secrets.
In the Wang family's blacksmith shop, Wang Tietou, the head of the family, got the blueprint of the spring and looked left and right but didn't understand it.
"Why does Mr. Li bend fine iron into circles like this?"
Li Zhi did not answer Wang Tietou's words, but said: "You don't have to worry about what I do, you just make it."
Li Zhi was dressed in silk and satin clothes, and his temperament was different from ordinary people. Wang Tietou was not angry when Li Zhi choked him, he just felt that people from rich families should be so domineering.
"Master Li, I will charge you thirty copper coins for making this."
"Easy to say!"
Even if Li Zhi was just a toy, what did he have to do with Wang Tietou? As long as Li Zhi was willing to pay, Wang Tietou stopped talking and started making springs according to Li Zhi's drawings.
He heated a piece of fine iron red, placed it on the anvil and beat it repeatedly until it became a thick wire as thick as incense. Then he used pliers to wrap the thick wire around a wooden stick, making it
He picked a spring, and finally put the spring in water to quench it.
Li Zhi was very happy when he saw that he had made it, so he went to test the elasticity of the spring. However, after trying it for a few times, Li Zhi felt that the elasticity of the spring was relatively average, and it would lose elasticity and deform if pressed too much.
Li Zhi thought for a while and felt that this might be caused by the insufficient elasticity of iron. The springs in later generations were all made of special spring steel. No matter how difficult it was, steel had to be used. It was probably difficult for springs made of iron to meet the requirements.
Especially using the inferior iron from Ming Dynasty blacksmiths.
"Wang Tietou, don't use iron to do this, find a piece of fine steel to do it!"
Wang Tietou was stunned and said: "Master Li, fine steel is used on the blade. Isn't it too extravagant for you to use fine steel for this thing?"
Li Zhi shook his head and said, "How much does it cost to make it with fine steel?"
Wang Tietou thought for a moment and said, "I'm afraid I need a penny."
Li Zhi smiled and said: "If you do it boldly, I will give you a lot of money." After a pause, Li Zhi said again: "Knead the steel wire a little thinner, it should be more than half as thick as this one."
.”
After wiping his sweat, Wang Tietou said: "Okay! Since Mr. Li is willing to pay the money, I will just waste it."
Wang Tietou blew up the bellows again and heated the found piece of fine steel red. After beating for a quarter of an hour, the piece of fine steel was beaten into thin strips and wrapped around a wooden stick. Finally, it was quenched.
A steel spring is ready.
Li Zhi tried the steel spring and found that the effect was good. However, Li Zhi was not satisfied, so he asked Wang Tietou to change the winding angle and the thickness of the steel wire, and made more than a dozen different steel springs, and finally found the one with the greatest elasticity.
One, then gave up.
Once the spring with high elasticity is ready, other components will be easy. Li Zhi asked several blacksmiths to make guide rails and sinking rails. Finally, he asked a carpenter to make a new loom that was twice as wide as the Ming Dynasty loom.
The shuttle is mounted on it.
In order to keep it secret, Li Zhi wrapped the shuttle on the loom with several wooden boards to prevent the loom operator from seeing the structure of the shuttle.
After the loom was finished, Li Zhi took some cotton yarn from his mother and tried it once. Every time the shuttle crossed the warp and weft, the loom would return to the thread according to Li Zhi's operation, and the weaving speed
It was very impressive. Li Zhi worked for an hour and weaved two feet of wide cloth. The efficiency was twice that of the Ming Dynasty loom. In addition, the width of the loom was twice that of the Ming Dynasty loom. The cloth weaved was
Both were twice as wide, and the final overall efficiency was four times that of the Ming Dynasty looms.
Zheng stood aside and saw Li Zhi's weaving speed with a look of disbelief. After weaving for thirty years, Zheng considered herself a veteran weaver and was proud that she could weave faster than ordinary people.
Some. But she never thought that relying on the power of machines instead of experience, weaving could be so fast and such wide cotton could be weaved. If she hadn't seen it with her own eyes, Zheng would never have believed it in the world.
And such a wonderful machine.
Zheng looked at Li Zhi's loom and sighed. In front of this new loom, wouldn't all her thirty years of hard work have turned into stupid skills? If only Li Zhi had taken out this loom earlier
, wouldn’t the output of weaving one’s own cloth be several times more?
First there was soap, and then there was this kind of loom. Li Zhi was no longer the silly son, but a son full of magic. I don’t know why the Taoist priest Li Zhi mentioned was so good to Li Zhi and taught Li Zhi
Plant so many wonderful things.
Li Zhi didn't take Zheng's surprise seriously. Anyone would be surprised by his inventions that were far ahead of the times.
Li Zhi was in a good mood after making a flying shuttle loom. Making this kind of loom required blacksmiths and carpenters, and the cost was about three taels of silver per unit. Li Zhi could afford to make hundreds of them. Li Zhi was ready to build a successful loom.
A large-scale weaving factory purchased 400 looms at one time and hired 400 weavers.
This requires a factory with a large space.
It is impossible to find such a large factory building in the city. The houses in the Ming Dynasty were all courtyard structures, with small rooms and large courtyards, and the land utilization rate was very low. If five looms were placed in one house, eighty houses would be needed.
These days, houses with eighty rooms are all gorgeously decorated mansions! Li Zhi may not be able to afford them if he spends all his wealth.
Li Zhi planned to locate the factory outside the city where land was cheap and find a piece of vacant land to build a large factory.
If a loom covers an area of three square meters, Li Zhi needs to build a factory of 1,200 square meters. This is not a big project, and it can be done quickly by hiring dozens of carpenters and masons.
