[0024] In the following description, many specific details are set forth to fully understand the present utility model.

When describing the embodiments of the present utility model in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally in a non-general proportion, and the schematic diagrams are only examples, which should not limit the scope of protection of the present utility model herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0026] To make the purpose, technical solution, and advantages of the present utility model clearer, the following will further describe in detail the embodiments of the present utility model with reference to the accompanying drawings.

[0027] The present utility model provides a flat knitting machine roller drive structure. Under the action of the spring, the bushing moves outwards, thereby promoting the inserting shaft to be inserted into the connection hole. A torsion spring is arranged between the inserting shaft and the bracket to ensure stable contact between the upper roller and the lower roller. When it needs to be disassembled and replaced, the connecting rod is squeezed to make the spring contract, and the inserting shaft withdraws from the connection hole to complete the disassembly of the upper roller. During installation, the spring rebounds to make the inserting shaft inserted into the connection hole to complete the connection, which is convenient for quick disassembly and replacement for maintenance. Please refer to Figures 1 - 3 , including: a fixed mechanism 100 and a movable mechanism 200.

[0028] The fixed mechanism 100 includes a bracket 110, a lower roller 120, a driving component 130, and a connection hole 140. The lower roller 120 is arranged at the lower part of the bracket 110, the driving component 130 connected to the lower roller 120 is arranged at the side of the bracket 110, and the connection hole 140 is opened at the upper part of the bracket 110;

[0029] Among them, the driving component 130 uses a rotating motor to drive the lower roller 120 to rotate through the driving component 130, providing the pulling power.

[0030] The movable mechanism 200 is connected to the connection hole 140. The movable mechanism 200 includes an upper roller 210, a rotating shaft 220, a connecting rod 230, an inserting shaft 240, a shaft sleeve 250, a spring 260, and a torsion spring 270. Rotating shafts 220 are arranged at both ends of the upper roller 210. An inserting shaft 240 inserted into the connection hole 140 is arranged at one end of the connecting rod 230. A shaft sleeve 250 sleeved on the rotating shaft 220 is arranged at the other end of the connecting rod 230. A spring 260 is arranged outside the rotating shaft 220. A torsion spring 270 is arranged between the inserting shaft 240 and the bracket 110;

[0031] Among them, the lower roller 120 and the upper roller 210 are parallel to each other. In the natural state of the spring 260, the inserting shaft 240 is inserted into the connection hole 140. In the contracted state of the spring 260, the inserting shaft 240 withdraws from the connection hole 140, realizing the connection and disassembly of the inserting shaft 240 and the connection hole 140. In the natural state of the torsion spring 270, the upper roller 210 and the lower roller 120 are in contact, and the upper roller 210 rotates following the lower roller 120 to pull the yarn.

[0032] To ensure the pulling stability and avoid the yarn from slipping, anti-slip convex patterns are provided on the outer surfaces of both the lower roller 120 and the upper roller 210. The anti-slip convex patterns on the lower roller 120 and the upper roller 210 are meshed with each other to increase the friction force and facilitate the pulling of the yarn.

[0033] To ensure the rotational stability, a bearing is arranged between the shaft sleeve 250 and the rotating shaft 220. The bearing is fixedly connected to the shaft sleeve 250 and is slidably connected to the rotating shaft 220, enabling the bearing to slide on the rotating shaft 220 under the support of the spring 260.

[0034] During specific use, the driving component 130 drives the lower roller 120 to rotate, and the upper roller 210 rotates following the lower roller 120 to pull the yarn. When disassembly is required, the connecting rod 230 is pushed to make the shaft sleeve 250 slide towards the upper roller 210, compressing the spring 260. At the same time, the connecting rod 230 drives the inserting shaft 240 to withdraw from the connection hole 140, completing the disassembly of the upper roller 210. During installation, the installation position is aligned, and the spring 260 rebounds to make the inserting shaft 240 inserted into the connection hole 140, facilitating quick disassembly and replacement for maintenance.

[0035] Although the present utility model has been described above with reference to the embodiments, various improvements can be made thereto and components therein can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed by the present utility model can be combined with each other in any way, and the reasons for not exhaustively describing the situations of these combinations in this specification are only for saving space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
