Description

Technical Field

[0001] The utility model relates to a textile cylinder assembly which is easy to disassemble and assemble, and belongs to the field of cylinder assemblies. Background Art

[0002] A textile cylinder, also known as a needle roller, is a metal cylinder with steel needles planted on its surface. Its main body is usually composed of a copper cylinder. Small holes are drilled on the surface of the cylinder, and steel needles are planted in the holes. This structure enables the needle roller to have a specific use in textile machinery. A flange is installed at each end of the needle roller, and its surface is slightly higher than the tip of the needle. Such a design aims to protect the tip of the needle from damage. The needle roller is used in the no-twist roving frame of silk spinning and wool spinning, the fine spinning frame of woolen spinning, and the fine spinning frame of silk spinning and shaft spinning, and is mainly used for controlling and carding fibers.

[0003] The Chinese patent discloses a needle roller for a spinning machine (publication number: CN221166899U), which includes a needle roller assembly and a connection assembly. The needle roller assembly includes a cylinder body and a plurality of needle teeth vertically arranged at equal intervals on the outer wall of the cylinder body. A plurality of channels are opened on the outer wall of the cylinder body, and a needle tooth is vertically arranged in each channel. The connection assembly includes a connection ring installed on the outer side of the middle part of one end of the cylinder body and a threaded hole opened on the outer side of the middle part of the other end of the cylinder body. An external thread is arranged on the outer wall of the connection ring, and the connection ring is threadedly connected with the threaded hole.

[0004] The existing textile cylinders are usually integrally designed. However, during use, if the cylinder needles or cylinder sleeves are damaged, it is not only difficult to repair but also difficult to replace. As a result, a new textile cylinder needs to be replaced for use, reducing the service life and increasing the processing cost. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a textile cylinder assembly which is easy to disassemble and assemble, so as to solve the problems that the existing textile cylinders are usually integrally designed, but during use, if the cylinder needles or cylinder sleeves are damaged, it is not only difficult to repair but also difficult to replace. As a result, a new textile cylinder needs to be replaced for use, reducing the service life and increasing the processing cost.

[0006] To achieve the above purpose, the utility model is realized through the following technical solutions: A textile cylinder assembly which is easy to disassemble and assemble includes a connecting rod, a connecting head, an auxiliary structure, a sleeve and cylinder needles. Connecting heads are arranged at the left and right ends of the connecting rod. The inner side of the auxiliary structure is connected to the sleeve, and cylinder needles are arranged on the outer surface of the sleeve. The auxiliary structure includes a limit sleeve, a rubber ring, a nested card, an internal thread and an external thread. The left end of the limit sleeve is integrally fixed with the rubber ring. A nested card is arranged at the left end of the limit sleeve, and internal and external threads are arranged on the inner and outer sides of the nested card. The inner and outer sides of the nested card are respectively connected to the connecting head.

[0007] Further, the thread pitches of the internal thread and the external thread are the same.

[0008] Further, threads connected to the internal thread are provided on the outer side of the connecting rod.

[0009] Further, threads connected to the external thread are provided on the inner side of the sleeve.

[0010] Further, the barrel needles are distributed in an annular array along the center of the sleeve.

[0011] Advantages: For a textile needle barrel assembly of the present utility model that is easy to disassemble and assemble, by providing an auxiliary structure on the inner side of the sleeve, the internal thread and the external thread provided on both the inner and outer sides of the limiting sleeve are convenient for limiting and fixing the connecting rod and the sleeve, making it a modular structure, facilitating better assembly and disassembly by the staff, and also facilitating the replacement of damaged parts of the barrel needles. Thereby, not only the service life of the barrel needles is improved, but also the processing cost is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the purposes, technical solutions, and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0017] Please refer to Figure 1, the present utility model provides an easily detachable and assembled textile needle cylinder assembly through improvement, which includes a connecting rod 1, a connecting head 2, an auxiliary structure 3, a sleeve 4 and a cylinder needle 5. Connecting heads 2 are arranged at both the left and right ends of the connecting rod 1. Threads connected to the internal thread 34 are provided on the outer side of the connecting rod 1. The inner side of the auxiliary structure 3 is connected to the sleeve 4. Threads connected to the external thread 35 are provided on the inner side of the sleeve 4. And cylinder needles 5 are arranged on the outer surface of the sleeve 4. The cylinder needles 5 are distributed in an annular array along the center of the sleeve 4. The setting of the connecting head 2 facilitates the connection with external textile equipment.

[0018] Please refer to Figure 2 , the present utility model provides an easily detachable and assembled textile needle cylinder assembly through improvement. The auxiliary structure 3 includes a limit sleeve 31, a rubber ring 32, a clamping sleeve 33, an internal thread 34 and an external thread 35. The left end of the limit sleeve 31 is integrally fixed with the rubber ring 32. A clamping sleeve 33 is arranged at the left end of the limit sleeve 31. And internal threads 34 and external threads 35 are arranged on the inner and outer sides of the clamping sleeve 33. The thread pitches of the internal thread 34 and the external thread 35 are the same. The inner and outer sides of the clamping sleeve 33 are respectively connected to the connecting head 2. The rubber ring 32 can provide a certain buffering effect.

[0019] The working process is as follows:

[0020] 1. When a staff member needs to replace the sleeve 4, an external ring wrench can be used to be sleeved on the limit sleeve 31, and then the wrench is rotated with force to separate the internal thread 34 from the thread provided on the outer side of the connecting rod 1, and the external thread 35 will also be separated from the thread provided on the inner side of the sleeve 4. After the thread locking states of the limit sleeves 31 at both ends are released, the limit sleeve 31 can be removed from the connecting rod 1, and thus the sleeve 4 can be replaced. After the replacement is completed, repeating the above steps can achieve the effect of locking the sleeve 4, and the setting of the rubber ring 32 can achieve a good buffering and anti-collision effect;

[0021] 2. Subsequently, the connecting head 2 can be connected and fixed to external textile equipment, and then the cylinder needles 5 can be used to comb the textile.
