Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a special-shaped tube compact spinning device. Background Art

[0002] At present, many cotton spinning enterprises use compact spinning devices to reduce the hairiness of yarns, increase the strength of yarns, improve the quality of yarns, and enhance market competitiveness. The existing special-shaped tube compact spinning device generally includes two front and rear grid rings, a special-shaped tube, rollers, and a tensioning device. The top surface of the special-shaped tube forms an arc-shaped working surface, and a cylindrical reinforcing rib is formed on the bottom surface of the special-shaped tube. The special-shaped tube is installed on the top of the tensioning device through the cylindrical reinforcing rib, and the rollers are located on the side of the special-shaped tube. The rollers, the special-shaped tube, and the tensioning device are installed between the two front and rear grid rings.

[0003] In the prior art, the tensioning device is a fixed structure, which plays a role in supporting and limiting the special-shaped tube, so that a certain gap is maintained between the special-shaped tube and the rollers, so that the rollers, the special-shaped tube, and the tensioning device form a stable triangular structure. However, when the compact spinning sliver is output from the rollers, the compact spinning sliver runs upward to the special-shaped tube. There is a certain gap between the rollers and the special-shaped tube. In production, if the tensioning device fails slightly or has defects, the gap between the rollers and the special-shaped tube will continue to increase, and the compact spinning sliver cannot smoothly transition to the special-shaped tube, resulting in serious sticking of the rollers, a lot of entanglement of the compact spinning rollers, a lot of cotton grain tube yarns, and relatively large potential quality hazards of the evenness, resulting in more waste yarns being cut out and lower strength of the yarns, causing waste of resources. Summary of the Utility Model

[0004] In order to overcome the defect that the gap between the rollers and the special-shaped tube in the prior art continuously increases, the utility model provides a special-shaped tube compact spinning device.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a special-shaped tube compact spinning device, including symmetrically arranged grid rings. A special-shaped tube and rollers are installed in the cavity between the symmetrically arranged grid rings. The rollers are arranged on the side of the special-shaped tube. A tensioning device capable of supporting and limiting the special-shaped tube is provided at the lower part of the special-shaped tube. The lower end of the tensioning device is hinged to a first pin shaft. A telescopic cylinder is arranged on the side of the tensioning device. The output end of the telescopic cylinder is hinged to the tensioning device. The bottom end of the telescopic cylinder is hinged to a second pin shaft. The first pin shaft and the second pin shaft are installed in the cavity between the symmetrically arranged grid rings.

[0006] As a further improvement of the utility model, the tensioning device includes a base and a tensioning plate, and the base and the tensioning plate are connected by a torsion spring.

[0007] As a further improvement of the utility model, a groove for limiting and fixing the special-shaped tube is provided on the tensioning plate.

[0008] As a further improvement of the present utility model, a ring column capable of fitting into the groove is provided at the lower part of the special-shaped tube.

[0009] As a further improvement of the present utility model, the top surface of the special-shaped tube is an arc-shaped working surface.

[0010] As a further improvement of the present utility model, the side surface of the special-shaped tube is an arc-shaped working surface concentric with the roller.

[0011] Compared with the prior art, the present utility model has the following beneficial effects: In this solution, when the telescopic cylinder works, the tensioning device will rotate towards the roller direction, causing the special-shaped tube at the top of the tensioning device to slowly approach the roller, reducing the distance between the special-shaped tube and the roller. The compacted cotton sliver can smoothly transition onto the special-shaped tube, reducing roller sticking. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0015] In order to make the technical solution and beneficial effects of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with specific embodiments.

[0016] Refer to Figure 1 , an embodiment of the present utility model discloses a special-shaped tube compact spinning device, including symmetrically arranged grid rings 1. A special-shaped tube 2 and a roller 3 are installed in the cavity between the symmetrically arranged grid rings 1. The roller 3 is arranged on the side of the special-shaped tube 2. A tensioning device 4 capable of supporting and limiting the special-shaped tube 2 is provided at the lower part of the special-shaped tube 2. The lower end of the tensioning device 4 is hinged to the first pin shaft 5. A telescopic cylinder 6 is provided on the side of the tensioning device 4. The output end of the telescopic cylinder 6 is hinged to the tensioning device 4. The bottom end of the telescopic cylinder 6 is hinged to the second pin shaft 7. The first pin shaft 5 and the second pin shaft 7 are installed in the cavity between the symmetrically arranged grid rings 1.

[0017] Among them, the tensioning device 4 includes a base 8 and a tensioning plate 9. The base 8 and the tensioning plate 9 are connected by a torsion spring 10. A groove 11 for limiting and fixing the special-shaped tube 2 is provided on the tensioning plate 9. A ring column 12 capable of fitting into the groove 11 is provided at the lower part of the special-shaped tube 2, so that the special-shaped tube 2 is more firmly fixed on the tensioning plate 9.

[0018] When the tensioning device fails slightly or has defects, the gap between the roller and the profiled tube continuously increases, and the telescopic cylinder 6 works. Since the lower end of the tensioning device 4 is hinged to the first pin shaft 5, the bottom end of the telescopic cylinder 6 is hinged to the second pin shaft 7, and the output end of the telescopic cylinder 6 is hinged to the tensioning device 4. When the telescopic cylinder 6 works, it will cause the tensioning device 4 to rotate towards the roller 3, making the profiled tube 2 at the top of the tensioning device 4 slowly approach the roller 3, reducing the distance between the profiled tube 2 and the roller 3, and enabling the compacted cotton sliver to smoothly transition onto the profiled tube 2, reducing roller sticking.

[0019] The top surface of the profiled tube 2 is an arc-shaped working surface, making the transition smoother. The side surface of the profiled tube 2 is an arc-shaped working surface concentric with the roller 3. With the concentric arc setting, the distance between the profiled tube 2 and the roller 3 can be relatively small.

[0020] It should be understood that the specific embodiments described herein are only for understanding the present invention and are not used to limit the present invention. All other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present invention.
