DETAILED DESCRIPTION

[0028] The utility model will be further explained in detail in combination with the drawings.

[0029] Example 1:

[0030] Reference Figure 1 , Figure 2A spinning scraper mechanism includes a mounting plate 1, wherein an upper adjusting rod 2 and a lower adjusting rod 3 are respectively connected and rotated through the interior of the mounting plate 1. A scraper plate 6 is symmetrically fixedly sleeved on the surface of each of the upper adjusting rod 2 and the lower adjusting rod 3. A spinning bundle 7 is slidably connected between the two scraper plates 6. A mutually meshing transmission gear 4 is bolted to the surface of each of the upper adjusting rod 2 and the lower adjusting rod 3 on the side away from the scraper plates 6. A return spring 5 bolted to the mounting plate 1 is welded to the side of each of the two transmission gears 4 near the scraper plates 6. The two return springs 5 ​​are respectively sleeved on the surfaces of the upper adjusting rod 2 and the lower adjusting rod 3. The two transmission gears 4 are meshed with each other, causing the upper adjusting rod 2 and the lower adjusting rod 3 to rotate synchronously in opposite directions to open the scraper plates 6 for thread drawing. After the thread drawing is completed, the return force of the return spring 5 is used to make the scraper plates 6 fit tightly back onto the surface of the spinning bundle 7. This facilitates thread drawing for spinning while ensuring the scraping effect.

[0031] refer to Figure 1 , the mounting plate 1 is rotatably connected to a transmission wheel 15 which is transmission-connected with the spinning bundle 7 near one side of the acid scraping plate 6. The spinning bundle 7 can scrape acid at an inclined angle, and the spinning bundle 7 moves upward in an inclined manner, so that the acid scraped off can drip better.

[0032] refer to Figure 2 , an end of the upper regulating rod 2 away from the acid scraping plate 6 is welded with a handle 16. It is convenient to twist the handle 16 to drive the upper regulating rod 2 to rotate, thereby the acid scraping plate 6 is opened for wire drawing.

[0033] refer to Figure 1 、 Figure 2 , two acid scrapers 6 are welded with side scrapers 17 that are slidably connected with spinning bundle 7 on one side that is close to each other. Acid can be scraped off the left and right sides of spinning bundle 7 to improve the acid scraping effect.

[0034] A brief description of the operating process: By rotating the upper adjusting rod 2, the two transmission gears 4 engage with each other, thereby synchronously driving the lower adjusting rod 3 to rotate in the opposite direction of the upper adjusting rod 2. When the upper adjusting rod 2 drives the top scraper 6 to rotate and open to one side, the lower adjusting rod 3 can drive the bottom scraper 6 to rotate and open to the other side, allowing the spinning bundle 7 to pass through it for thread drawing. At the same time, the rotation of the upper and lower adjusting rods 2 and 3 causes the return spring 5 to twist, thereby loosening the upper adjusting rod 2 after thread drawing is completed. The torsional rebound force of the return spring 5 causes the scraper 6 to automatically adhere to the upper and lower surfaces of the spinning bundle 7, allowing the scraper 6 to scrape the acid as the spinning bundle 7 slides.

[0035] Example 2:

[0036] refer to Figure 1 、 Figure 2 、 Figure 3The invention discloses an acid scraping mechanism for spinning. The bottom of the acid scraping plate 6 is provided with an acid receiving box 8 bolted to a mounting plate 1. An electric motor 9 is bolted to the side of the mounting plate 1 away from the acid receiving box 8. A sliding plate 10 is slidably connected to the interior of the acid receiving box 8. Both sides of the sliding plate 10 are provided with through grooves 11. An acid filter net 12 is bolted to the interior of the through groove 11. An arc rod 13 is bolted to the output end of the electric motor 9. An arc groove 14 is provided inside the sliding plate 10 and is slidably connected to the arc rod 13. After scraping, the acid falls into the interior of the acid receiving box 8, causing the sliding plate 10 to shake left and right to drive the acid filter net 12 to filter the acid, thereby filtering out the spinning fibers inside. This prevents the spinning fibers from entering the acid pool along with the scraped acid, thereby improving practicality.

[0037] refer to Figure 3 , both sides at the top of the acid box 8 are provided with a diversion chute 18. The dripping acid can be concentrated and slided into the inside of the through groove 11 to improve the filtering efficiency.

[0038] refer to Figure 3 , both sides of sliding plate 10 are all welded with the vibration spring 19 that is connected with the inner bolt of acid box 8. Utilize the resilience of vibration spring 19 to slide plate 10 and reset automatically, improve the shaking filtering effect of sliding plate 10 simultaneously.

[0039] refer to Figure 1 、 Figure 2 、 Figure 3 The acid scraper 6 and side scraper 17 are made of PE. The acid receiving box 8, sliding plate 10, and acid filter 12 are all coated with acid-resistant coating. Using PE can reduce the phenomenon of broken and stuck yarns during spinning. At the same time, the acid-resistant coating can prevent acid corrosion and extend the service life.

[0040] Brief description of the operating process: By turning on the electric motor 9, the arc rod 13 is driven to rotate inside the arc groove 14. The force of the arc rod 13 and the arc groove 14 can push the sliding plate 10 to slide back and forth inside the acid receiving box 8. After the acid on the surface of the spinning bundle 7 is scraped off, it falls into the acid receiving box 8 due to gravity. Then, the sliding plate 10 drives the acid filter net 12 to swing left and right to filter the acid, so that the spun fibers inside are filtered out and then fall downward into the acid pool.
