Description

Technical Field

[0001] This utility model belongs to the field of textile machinery technology, specifically relating to a small roller with adjustable diameter for compact spinning. Background Technology

[0002] In recent years, cotton spinning enterprises have faced fierce market competition and an urgent need for transformation and upgrading, with many enterprises shifting to the production of chemical fibers such as lyocell. However, existing compact spinning equipment has exposed key technical problems during the product switching process: taking the Wuxi Wanbao compact spinning unit as an example, the diameter of its special-shaped tube small roller is fixed. When production is switched from cotton to chemical fibers such as lyocell, the original draft ratio of the gathering zone cannot adapt to the processing requirements of the new fiber, causing the sliver to shake and poorly gather on the mesh ring, ultimately resulting in an increase in yarn neps and affecting product quality.

[0003] To address these issues, existing enterprises primarily employ two solutions: one is to replace the entire compact spinning unit (e.g., by switching to Tonghe compact spinning), which incurs high modification costs; the other is to replace the small rollers with different diameter profiles, replacing the original 18.7mm diameter rollers with 19mm, 19.14mm, or other specifications suitable for chemical fiber production. However, the purchase cost of a single small roller is approximately 65 yuan. For large-scale production enterprises, the total investment in replacing all equipment in the workshop is enormous, significantly increasing the operational burden on the enterprise. Furthermore, the replacement process is cumbersome and affects production efficiency.

[0004] There is a lack of a low-cost solution in the existing technology that can flexibly adjust the draw ratio without replacing the entire small roller. Therefore, there is an urgent need to design a small roller for special-shaped tubes that is simple in structure, easy to adjust, and cost-controllable, in order to meet the needs of enterprises for product transformation and upgrading. Summary of the Invention

[0005] To overcome the shortcomings of the existing technology, the purpose of this invention is to provide a small roller with an adjustable diameter for compact spinning, which solves the technical problems of inconvenient adjustment of the draft ratio and high cost of replacing small rollers when switching between varieties in existing compact spinning equipment, and enables a single roller to be adapted to the production of multiple fiber varieties, thereby reducing the transformation costs of enterprises.

[0006] To achieve the above-mentioned objectives, this utility model provides a compact spinning diameter adjustable profiled tube roller, comprising a roller body and a cylinder. The roller body has a rectangular hole inside, and a support block is fixedly connected to the inner wall of the rectangular hole. First nuts are fixedly connected to the upper and lower sides of the support block. First grooves are formed on the upper and lower sides of the inner wall of the cylinder. Fixing pins are fitted into the inner walls of the first grooves and the inner walls of the rectangular hole. First circular holes are formed inside the fixing pins. First bolts are fitted into the inner walls of the first circular holes and the surface of the fixing pins. Fixing grooves are formed on the sides of the fixing pins. Fixing blocks are fixedly connected to the inner walls of the first grooves, and the surface of the fixing blocks is fitted into the inner walls of the fixing grooves. An arc-shaped plate is fixedly connected to the inner wall of the cylinder. A conical hole is formed inside the arc-shaped plate, and steel balls are fitted into the inner walls of the conical hole and the inner walls of the cylinder. A guide groove is formed on the surface of the roller body, and the inner wall of the guide groove is fitted into the surface of the steel balls.

[0007] The present invention is further configured such that a bearing is sleeved on the surface of the roller body, a fixing plate is fixedly connected to the inner ring of the bearing, a second circular hole is opened inside the fixing plate, a second groove is opened on both the left and right sides of the roller body, the inner wall of the second groove is in contact with the surface of the fixing plate, a second bolt is in contact with the inner wall of the second circular hole and the side of the fixing plate, a second nut is fixedly connected to the inner wall of the second groove, and the inner wall of the second nut is threadedly connected to the surface of the second bolt.

[0008] The present invention is further configured such that the axis of the second bolt coincides with the axis of the roller body.

[0009] The present invention is further configured such that there are two arc-shaped plates, and the two arc-shaped plates are respectively located on the front and rear sides of the roller body.

[0010] The present invention is further configured such that the axis of the cylinder coincides with the axis of the roller body, and the distance between the inner wall of the cylinder and the surface of the roller body is greater than the thickness of the arc plate.

[0011] The present invention is further configured such that the diameter of the conical hole on the side near the roller body is smaller than the diameter of the steel ball, and the diameter of the conical hole on the side near the cylinder is larger than the diameter of the steel ball.

[0012] Compared with the prior art, the technical effects achieved by this utility model are as follows: 1. This utility model discloses a compact spinning adjustable diameter profiled tube roller. Through the cooperation of the roller body, cylinder, rectangular hole, support block, first nut, first groove, fixing pin, first round hole, first bolt, fixing groove and fixing block, the cylinder and roller body can be quickly disassembled and assembled. At this time, by replacing the cylinder with a cylinder of different diameter, the draft ratio of the gathering zone can be precisely adjusted without replacing the entire small roller. It can be adapted to the production needs of various fiber varieties such as cotton and lyocell, and solve the problem of poor gathering when switching varieties. Moreover, the manufacturing cost of a single cylinder is much lower than that of a complete small roller (only 1 / 5 to 1 / 3 of the cost of a small roller). Enterprises do not need to repeatedly purchase multiple specifications of small rollers, which greatly reduces the equipment investment for product transformation and upgrading.

[0013] 2. This utility model discloses a compact spinning diameter adjustable irregular tube small roller. Through the steel ball that can rotate freely inside the arc plate, and the existence of a certain gap between the arc plate and the roller body, the cylinder moves more smoothly on the roller body. Furthermore, through the cooperation of the steel ball and the guide groove, the user can quickly align the first groove on the cylinder with the rectangular hole when installing the cylinder. At the same time, through the cooperation of the fixing plate, the second circular hole, the second groove, the second bolt, and the second nut, the user can quickly complete the disassembly and assembly of the bearing by rotating the second bolt, thus making the cylinder replacement process more convenient.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the present invention discloses a compact spinning diameter adjustable profiled tube roller comprising a roller body 1 and a cylinder 2. A rectangular hole 3 is formed inside the roller body 1, and a support block 4 is fixedly connected to the inner wall of the rectangular hole 3. First nuts 5 are fixedly connected to both the upper and lower sides of the support block 4. First grooves 6 are formed on both the upper and lower sides of the inner wall of the cylinder 2. Fixing pins 7 are fitted into the inner walls of the first grooves 6 and the inner walls of the rectangular hole 3. First circular holes 8 are formed inside the fixing pins 7. The inner walls of the first circular holes 8 and the fixing pins... The surface of the cylinder 7 is fitted with a first bolt 9. The side of the fixing pin 7 is provided with a fixing groove 10. The inner wall of the first groove 6 is fixedly connected with a fixing block 11. The surface of the fixing block 11 is fitted with the inner wall of the fixing groove 10. The inner wall of the cylinder 2 is fixedly connected with an arc plate 12. The inside of the arc plate 12 is provided with a conical hole 13. The inner wall of the conical hole 13 and the inner wall of the cylinder 2 are both fitted with steel balls 14. The surface of the roller body 1 is provided with a guide groove 15. The inner wall of the guide groove 15 is fitted with the surface of the steel ball 14.

[0026] There are two arc-shaped plates 12, which are located on the front and rear sides of the roller body 1 respectively. The axis of the cylinder 2 coincides with the axis of the roller body 1. The distance between the inner wall of the cylinder 2 and the surface of the roller body 1 is greater than the thickness of the arc-shaped plate 12. The diameter of the conical hole 13 on the side closer to the roller body 1 is smaller than the diameter of the steel ball 14, while the diameter of the conical hole 13 on the side closer to the cylinder 2 is larger than the diameter of the steel ball 14.

[0027] It should be noted that the first nut 5 is supported by the support block 4. The fixing pin 7 can be fixed in the rectangular hole 3 through the cooperation of the first round hole 8, the first bolt 9, and the first nut 5. After the fixing pin 7 is fixed in the rectangular hole 3, the cylinder 2 cannot rotate on the roller body 1 through the cooperation of the fixing pin 7, the first groove 6, and the rectangular hole 3. Furthermore, the cylinder 2 cannot move left or right on the roller body 1 through the cooperation of the fixing block 11 and the fixing groove 10. At this point, the cylinder 2 can be moved by the cooperation of the rectangular hole 3, the support block 4, the first nut 5, the fixing pin 7, the first round hole 8, the first bolt 9, the first groove 6, the fixing block 11, and the fixing groove 10. The cylinder 2 is fixed on the roller body 1. After the first bolt 9 is separated from the first nut 5, the cylinder 2 can be removed from the roller body 1 by taking out the fixing pin 7 from the rectangular hole 3. At the same time, by replacing the cylinder 2 with cylinders of different diameters, the draft ratio of the gathering zone can be precisely adjusted without replacing the entire small roller. It can adapt to the production needs of various fiber varieties such as cotton and lyocell, and solve the problem of poor gathering when switching varieties. Moreover, the manufacturing cost of a single set of cylinder 2 is much lower than that of a complete small roller (only 1 / 5 to 1 / 3 of the cost of a small roller). Enterprises do not need to repeatedly purchase small rollers of multiple specifications, which greatly reduces the equipment investment for variety transformation and upgrading.

[0028] There is a certain gap between the arc plate 12 and the roller body 1. The steel ball 14 is held in the arc plate 12 through the conical hole 13. Since the steel ball 14 can rotate freely in the conical hole 13, the cylinder 2 moves more smoothly on the roller body 1. Furthermore, through the cooperation of the steel ball 14 and the guide groove 15, the user can quickly align the first groove 6 on the cylinder 2 with the rectangular hole 3 when installing the cylinder 2.

[0029] A bearing 16 is fitted onto the surface of the roller body 1. A fixing plate 17 is fixedly connected to the inner ring of the bearing 16. A second round hole 18 is opened inside the fixing plate 17. A second groove 19 is opened on both the left and right sides of the roller body 1. The inner wall of the second groove 19 is in contact with the surface of the fixing plate 17. A second bolt 20 is fitted into the inner wall of the second round hole 18 and the side of the fixing plate 17. A second nut 21 is fixedly connected to the inner wall of the second groove 19. The inner wall of the second nut 21 is threadedly connected to the surface of the second bolt 20.

[0030] The axis of the second bolt 20 coincides with the axis of the roller body 1.

[0031] It should be noted that when the fixing plate 17 is inserted into the second groove 19, the inner ring of the bearing 16 can be positioned by the cooperation of the fixing plate 17 and the second groove 19. When the second bolt 20 passes through the second round hole 18 and is screwed into the second nut 21, the fixing plate 17 can be fixed in the second groove 19 by the cooperation of the second bolt 20, the second round hole 18 and the second nut 21, and the bearing 16 can be fixed on the roller body 1. When the second bolt 20 is separated from the second nut 21, the bearing 16 can be directly removed from the roller body 1, so that the user can quickly complete the disassembly and assembly of the bearing 16 by rotating the second bolt 20, thus making the replacement process of the cylinder 2 more convenient.

[0032] The working principle of this utility model is as follows: During assembly, the bearings 16 at both ends of the roller body 1 are first removed. During disassembly, the bearings 16 can be removed from the roller body 1 by separating the second bolt 20 from the second nut 21. Then, according to the fiber type to be produced, a cylinder 2 with the corresponding diameter is selected and the cylinder 2 is fitted onto the roller body 1. At this time, the first groove 6 is aligned with the rectangular hole 3 by the cooperation of the steel ball 14 and the guide groove 15.

[0033] Then, the fixing pin 7 is inserted into the rectangular hole 3, and the fixing pin 7 is fixed in the rectangular hole 3 by the cooperation of the first round hole 8, the first bolt 9 and the first nut 5. At this time, the cylinder 2 cannot rotate on the roller body 1 by the cooperation of the fixing pin 7, the first groove 6 and the rectangular hole 3, and the cylinder 2 cannot move left and right on the roller body 1 by the cooperation of the fixing block 11 and the fixing groove 10. At this time, the cylinder 2 can be fixed on the roller body 1 by the cooperation of the rectangular hole 3, the support block 4, the first nut 5, the fixing pin 7, the first round hole 8, the first bolt 9, the first groove 6, the fixing block 11 and the fixing groove 10.

[0034] Then, the bearing 16 is re-sleeved onto the roller body 1, and the fixing plate 17 is inserted into the second groove 19. Then, the second bolt 20 is passed through the second round hole 18 and screwed into the second nut 21. At this time, the bearing 16 can be fixed on the roller body 1 by the cooperation of the second bolt 20, the fixing plate 17, the second round hole 18, the second groove 19 and the second nut 21.

[0035] During operation, the roller body 1 drives the cylinder 2 to rotate synchronously at high speed. The outer circumference of the cylinder 2 contacts the mesh ring for transmission. By changing the cylinder 2 with different diameters, the linear speed of the mesh ring is changed, thereby adjusting the draft ratio of the gathering zone: When producing cotton varieties, a cylinder 2 with a diameter of 18.7mm is selected, and the draft ratio is adapted to the gathering requirements of cotton fibers; when switching to Lyocell production, a cylinder 2 with a diameter of 19mm or 19.14mm is used to increase the draft ratio, straighten the Lyocell sliver, reduce yarn neps, and eliminate the need to replace the entire small roller, thus reducing equipment modification costs.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
