    When Yang Shaowen woke up after sleeping, his whole body was full of energy again, and he left yesterday's frustration behind.  The situation Yuan Baoshan mentioned only added some difficulties and constraints to his development of hand-woven textile machines, and also prompted him to consider the problem more comprehensively, but it does not mean that this road is completely unworkable.  Yuan Baoshan also said that as long as the handmade machines developed can show very obvious efficiency advantages over the machines used in family side jobs, it may not be impossible to open a handmade cotton textile factory.  He got up early in the morning and took Yang Yuhua to Yuan Huiqing's house to have breakfast.  Since sending his younger siblings to Yuan Huiqing's home for foster care, Yang Shaowen and Yang Yuhua went there every three days to eat and drink in order to save trouble.  When I arrived at Yuan Huiqing¡¯s house, the old man Yuan Baoshan was also there, sitting at the table preparing to drink porridge.  Sitting next to him were Shao Ming, Shao Kuan, Xiang Xiang and others, making the old man laugh.  Yuan Huiqing was on the side preparing bowls, chopsticks and food for everyone.  Yuan Baoshan stayed late in Lamma Town yesterday, so he stayed overnight at his daughter's house.  Seeing the old man there, Yang Shaowen was a little embarrassed.  "Yuan Lao Zao! Aunt Qing is very good at cooking. I am a thick-skinned person, so I often come here to satisfy my cravings!" "Haha, Xiao Qing is too lonely at home alone. She told me yesterday that there are juniors like you.  Nao Nao, she is even happier! "Yuan Baoshan came to Lamma Town with the purpose of seeing Yuan Huiqing.  His daughter has been a widow for many years, and her dependent granddaughter also ran away from home a few days ago. He is really worried about her.  Now that he sees her taking care of three children and the bustle of her home, Yuan Baoshan is relieved.  "Shao Wen, you look much better than yesterday?" "Well, when I woke up, I had the courage to overcome difficulties again. After we developed the mobile phone, we also encountered a lot of promotion problems  It¡¯s difficult, but we still came up with a solution to the family OEM system. So, as long as the developed machinery and equipment are good enough, there is always a way to promote it.¡± Yuan Baoshan felt relieved after hearing this.  "That's right. I'm telling you this because I want you to avoid taking some detours in the development process. I'm not trying to hurt you. I watched you develop the Jenny machine in your factory yesterday, and it really impressed me.  With some inspiration, we can really develop more advanced spinning equipment. " "Oh!" Yang Shaowen became interested. Yuan Baoshan is a man of words. What he said is very feasible.  "My idea is to combine part of the structure of your Jenny machine to transform our ancient big spinning wheel." "Big spinning wheel?" Yang Shaowen has never seen it, and he has never heard of anyone talking about it.  According to Yuan Baoshan's explanation, this large spinning wheel is a spinning machine recorded in the "Nongshu" written by Wang Zhen in the second year of Emperor Qing's reign of the Yuan Dynasty (1313).  According to book records, the transmission of the large spinning wheel is through a large bamboo tube and adopts a collective transmission similar to the dragon belt transmission.  It has many spindles for spinning, as many as thirty-two, and its productivity is significantly increased compared to a single-spindle spinning wheel.  However, they are mainly used for spinning linen and silk, but have never been used in cotton textiles.  As for why the technology of large spinning wheels with multiple spindles has not been applied to cotton textiles, it is mainly due to the differences in the processing processes of linen spinning, silk spinning and cotton spinning.  Silk is a long, continuous fiber. The troublesome step in the manufacturing process is reeling, which is to extract the monofilament from the cocoon and wind it around a small shaft.  The job of spinning is to twist the monofilaments to make them tight.  Silk is relatively easy to spin after it goes through the reeling process.  Ramie is a semi-long fiber, and the most time-consuming task in curing ramie is spinning. Once the ramie is blended, it is easy to spin.  Spinning cotton is different.  Cotton fibers are short and usually tangled together. Before spinning, cotton must be rolled into long and thin slivers.  During spinning, fibers are extracted from the cotton sliver to make it into fine and even yarn, and then the rotation of the spinning wheel is used to twist the yarn, and finally the spun yarn is wound on the spindle.  The yarn is slowly pulled out from the cotton sliver. This is a unique point in the cotton spinning process, which is not found in silk spinning or linen spinning.  Therefore, how to place the sliver when spinning cotton is a special problem.  The hand-operated spinning wheel rotates the spinning wheel with the right hand, and the cotton sliver held in the left hand is slowly moved away from the spindle. At this time, the cotton thread is pulled out to induce labor.  The spinner uses his feet to move the spinning wheel, holds the cotton sliver in his left hand, and draws and twists the yarn with his right hand.  A person's left hand can hold up to 4 tampons in 5 fingers.  Therefore, there is no shortage of records of three- and four-spindle spinning wheels in ancient Chinese technical classics.  It can be seen that in the history of cotton spinning in my country, the concept of "multiple spindles" has been around for a long time, but the number of spindles on the spinning wheel cannot exceed the limit of human fingers.  "I see that in the Jenny machine you developed, both the spindles and the cotton slivers move collectively through a crossbar placed on both sides of the frame. If this crossbar device is modified on a large spinning wheel, I think dozens of spindles can be produced.  Large cotton spinning wheels are also feasible! "Theoretically, to solve the problem of sliver placement on cotton spinning machines with more than 4 spindles, the simplest way is toThe method is to create a "big hand" to replace the spinner's left hand in order to hold more than 4 cotton slivers.  The crossbar device on the Jenny machine is equivalent to this "big hand". If the spinner holds the crossbar with his left hand and slowly pulls it to the left, gradually leaving the spindle, it replaces the work of manual thread drawing.  After listening to Yuan Baoshan¡¯s reform ideas, Yang Shaowen could not sit still and did not bother to eat breakfast. He quickly took him to the factory to develop a large cotton spinning wheel.  The factory where Yang Shaowen develops the Jenny Machine is a bit messy.  In order to develop a multi-spindle spinning machine that could spin roving, he tried many mechanical components, but they were not very successful. Many workpieces were placed everywhere by him, and he did not bother to sort them out.  Yuan Baoshan¡¯s sharp eyes found several cylindrical wooden parts and asked Yang Shaowen what they were for.  "This is a roller device, the translation of English roller." (Roller spinning, invented by White and Paul, is an important component of modern spinning machinery. It appeared before Jenny spinning, but there was no  Caused too much repercussions) Roller spinning was a topic that Yang Shaowen studied during this period.  He heard someone introduce that most of the mechanical spinning machines in Shanghai have this kind of device.  Yang Shaowen based on other people's vague explanation, and the English roller almost means "roller".  After thinking about it for a while, I understood its mechanism.  He asked craftsmen to build a wooden roller device that he hoped could be used in hand spinning machines.  It's just that the wooden structure is really not enough for use, and the steel structure is very uneconomical, so this structure was gradually abandoned.  Yuan Baoshan is also an excellent craftsman. After listening to Yang Shaowen's explanation, he understood the principle.  "My idea of ??modifying the big spinning wheel is to imitate the spinning action of a hand-operated single-spindle cotton spinning wheel. The principle of roller spinning should be the same as that of a foot-operated cotton spinning wheel. The two pairs of rollers at the front and back are equivalent to the left and right hands of the spinner.  Fingers. Chinese spinners rely on the distance between their hands to draw the cotton yarn through the gap between each pair of rollers, just like two fingers holding cotton slivers. The rotation speeds of the front and rear pairs of rollers are different.  Pull out the cotton threads. " "Yes, this is indeed the principle!" Seeing Yuan Baoshan's thoughtful look, Yang Shaowen knew that he was considering the feasibility of this plan again.  "Mr. Yuan, let's continue to study the big spinning wheel. I have given up on roller spinning!" "Why? From my understanding, this roller spinning should be able to control the draw ratio more accurately, and the yarn spun should be more flexible.  Uniform! "It is certain that it can spin better yarn. But it is not easy to make a qualified iron roller device, and I am afraid that the wooden structure cannot meet the requirements.  Up." After hearing his explanation, Yuan Baoshan said nothing more.  He himself also knows that the manufacturing cost of machines has always been a very sensitive factor.  I won¡¯t say more now.  In the next few days, Yang Shaowen and Yuan Baoshan developed a multi-spindle large spinning wheel suitable for cotton spinning based on the records of the large spinning wheel in the "Agricultural Book" and combined with the horizontal wood structure.
