Description

Technical Field

[0001] This utility model relates to the field of roller equipment, and in particular to an anti-slip roller assembly for a doubling twister. Background Technology

[0002] A doubling twister is a type of twisting equipment, essentially a type of yarn-combining equipment, also called a yarn-combining machine. It can achieve two twists in one revolution, increasing twisting efficiency several times over compared to traditional twisting equipment. It also increases package capacity, produces tens of thousands of meters without joints, significantly improves twisting quality, and has a lower layer height, making it particularly suitable for operation. Rollers are cylindrical rotating parts in textile machinery that play roles such as feeding, drafting, and output. They can be understood as rollers and shafts, and are widely used in drafting, carding, and conveying mechanisms. According to their function, they are classified into drafting rollers, feeding rollers, compression rollers, and working rollers.

[0003] However, existing rollers are usually one-piece structures, which require the entire unit to be replaced when the structure is damaged, which is quite troublesome.

[0004] Therefore, it is necessary to provide a new anti-slip roller assembly for a doubling machine to solve the above-mentioned technical problems. Utility Model Content

[0006] The anti-slip roller assembly for a doubling twister provided by this utility model includes a roller shaft one, a roller shaft two, and two opposing frames. The roller shaft one and the roller shaft two are rotatably mounted on the two frames respectively. The roller shaft one and the roller shaft two are detachably connected by a connecting assembly. A flange is fixedly connected to both roller shaft one and the roller shaft two. Roller rings are slidably connected to both roller shaft one and the roller shaft two. The two roller rings are detachably connected to the two flanges respectively.

[0007] Furthermore, the connecting assembly includes a connecting rod, with connecting plates fixedly connected to both ends of the connecting rod. The opposite ends of the roller shaft one and the roller shaft two are provided with connecting grooves that match the size of the connecting plates, and connecting bolts are provided in the connecting grooves.

[0008] Furthermore, one end of the roller ring is provided with a connecting plate, and the edge of the connecting plate is provided with a plurality of fixing bolts at equal intervals in the circumferential direction. The edge of the flange is provided with a plurality of connecting holes corresponding to the fixing bolts at equal intervals in the circumferential direction.

[0009] Furthermore, each of the roller shaft one and the roller shaft two has a bearing seat fitted at the end away from the connecting rod. The bearing seats are fixedly installed on the frame, and the roller shaft one and the roller shaft two are rotatably connected to the two bearing seats respectively.

[0010] Furthermore, the connecting rod and the connecting plate are integrally welded together.

[0011] Furthermore, both the roller ring and the connecting disc have a groove hole at their center that matches the outer surface dimensions of roller shaft one and roller shaft two.

[0012] Compared with related technologies, the anti-slip roller assembly for a doubling twister provided by this utility model has the following beneficial effects:

[0013] This utility model provides an anti-slip roller assembly for a twisting machine. In specific implementation, the roller ring is connected to the flange by fixing bolts to achieve clamping and traction of the yarn.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 This is a schematic diagram of the overall structure of the anti-slip roller assembly for a doubling machine provided by this utility model; Figure 2 A schematic diagram showing the disassembled structure of the anti-slip roller assembly for a doubling machine provided by this utility model; Figure 3 This is a cross-sectional view of the anti-slip roller assembly for a doubling machine provided by this utility model.

[0020] In the specific implementation process, such as Figures 1-3As shown, the anti-slip roller assembly for a doubling twister includes roller shaft 1, roller shaft 2, and two opposing frames 3. Roller shaft 1 and roller shaft 2 are rotatably mounted on the two frames 3 respectively. Roller shaft 1 and roller shaft 2 are detachably connected by a connecting assembly. Flanges 4 are fixedly connected to roller shaft 1 and roller shaft 2 respectively. Roller rings 5 ​​are slidably connected to roller shaft 1 and roller shaft 2 respectively. The two roller rings 5 ​​are detachably connected to the two flanges 4 respectively.

[0021] In a specific implementation, the connecting assembly includes a connecting rod 6, with connecting plates 7 fixedly connected to both ends of the connecting rod 6. The opposite ends of roller shaft 1 and roller shaft 2 are provided with connecting grooves 8 that match the size of the connecting plates 7. Connecting bolts 9 are provided in the connecting grooves 8. The connecting rod 6 and the connecting plates 7 are welded together as an integral structure. The fitting design of the connecting rod 6 and the connecting grooves 8 ensures that roller shaft 1 and roller shaft 2 remain synchronized when rotating, avoiding yarn slippage due to speed differences. The detachable connection design facilitates quick replacement of worn connecting rod 6 or roller shaft, reducing downtime for maintenance.

[0022] It should be noted that one end of the roller ring 5 is provided with a connecting plate 10, and the edge of the connecting plate 10 is provided with multiple fixing bolts 11 at equal intervals in the circumferential direction. The edge of the flange 4 is provided with multiple connecting holes corresponding to the fixing bolts 11 at equal intervals in the circumferential direction.

[0023] It should be noted that the ends of roller shaft 1 and roller shaft 2 away from the connecting rod 6 are both fitted with bearing seats 12. The bearing seats 12 are fixedly installed on the frame 3, and roller shaft 1 and roller shaft 2 are rotatably connected to the two bearing seats 12 respectively. The bearing seats 12 reduce frictional resistance and ensure the stability of the roller shaft when rotating at high speed.

[0024] Furthermore, the center of both the roller ring 5 and the connecting plate 10 is provided with a sliding groove hole that matches the outer surface dimensions of roller shaft 1 and roller shaft 2. The size design of the sliding groove hole allows the roller ring 5 to be finely adjusted within a certain range to compensate for the offset caused by changes in yarn tension.

[0025] The working principle provided by this utility model is as follows: When the device is in use, the roller ring 5 is connected to the flange 4 through the fixing bolt 11 to achieve clamping and traction of the yarn. The detachable design allows for the individual replacement of worn roller ring 5 or flange 4 without replacing the entire roller shaft. By adjusting the tightness of the fixing bolt 11, the clamping force between roller ring 5 and flange 4 can be changed to adapt to the friction characteristics of different yarn materials (such as staple fiber yarn and chemical fiber filament).

[0026] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
