Description

technical field

[0001] The invention belongs to the technical field of knitting machines, in particular to a roller device of a flat knitting machine. Background technique

[0002] The roller is a component used to pull the knitted fabric, and its function is to pull down the knitted fabric knitted by the needle bed. Because the roller has a certain distance from the needle plate, the roller cannot pull the fabric just woven. Therefore, a lifter is set between the roller and the needle plate, and the braided fabric on the needle plate is pulled to a position where the roller can be pulled by utilizing the lifter to rise. But in the lifting process of the lifting plate, the roller must be fully opened, so as to avoid collision with the lifting plate. However, in the prior art, the opening of the rollers may not be complete, resulting in a collision between the lifter and the rollers, which affects the service life of both. Another problem is: when the roller is opened, the...

Embodiment Construction

[0018] see figure 1 and Figure 4 . The driving gear 3 and the driven gear 4 of this specific embodiment mesh and rotate to drive the driving wheel 1 and the driven wheel 2 to rotate. The cam device 5 includes a fan-shaped cam 51 and a bearing 52 with a one-way self-locking function, and the cam 51 is installed on the driving wheel. On the shaft of 1, the rolling bearing 52 is installed on the shaft of the driven wheel 2, both of which are located at one end of the roller, and the outer circumference of the bearing 52 has an arc-shaped protrusion. below the joint. The cam 51 is self-locking in one direction and can only rotate counterclockwise relative to the driving wheel 1, and will be stuck when rotating clockwise. Therefore, when the driving wheel 1 rotates clockwise, the cam 51 rotates counterclockwise relative to each other, and the driving wheel 1 and the cam 51 can move with each other, so that the cam 51 can be locked by the arc-shaped protrusion on the bearing, so...
