Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a twisted edge coupling for a water jet loom. Background Art

[0002] During the weaving process of the water jet loom, the cloth edges are rough and not locked, so a structure is needed to twist the rough edges. A coupling is used in the twisting transmission at the lower head, and there is a connecting rubber filling in the middle to play a buffering role. Therefore, the connecting rubber bears a large transmission force and impact force and is very easy to be damaged. The replacement process and process are particularly cumbersome, and all related parts need to be removed to achieve replacement. During installation, it needs to be readjusted and leveled, which is time-consuming and labor-intensive.

[0003] The existing coupling used in water jet looms results in a large bearing capacity of the hem shaft, and it also bears the impact force when the machine is started, making it particularly vulnerable. Replacing the linkage rubber is particularly complicated and cumbersome, so a water jet loom hem coupling is needed to solve the above problems. Utility Model Content

[0004] The utility model provides a water jet loom hem coupling, aiming to solve the following problems: the hem shaft of the existing coupling has a large bearing capacity and bears the impact force when the machine is started, is particularly vulnerable, and is particularly complicated and cumbersome when replacing the linkage rubber.

[0005] The utility model is implemented as follows: a water jet loom hem coupling, comprising: a coupling A and a coupling B, wherein the coupling A and the coupling B are matched and the coupling A is provided with a slot, two couplings A and two couplings B are provided, and the two couplings A and the coupling B can be connected to the rotating shafts on both sides of the loom; a flat key, which is fixedly arranged on the rotating shaft of the loom, the coupling A can be connected to the coupling B so that the coupling A is stuck on the flat key, and the flat key is used to enable the rotating shaft of the loom on one side to drive the coupling A and the coupling B to rotate; a connecting mechanism, which is installed on the coupling A and the coupling B and is detachable, and is used to fix the coupling A and the coupling B to the rotating shaft of the loom.

[0006] Preferably, the connecting mechanism includes: a hexagon socket screw, which is arranged in cooperation with coupling A and coupling B, and a spring washer is sleeved on the hexagon socket screw. The hexagon socket screw and the spring washer are used to fix coupling A and coupling B to the loom shaft; an external hexagon socket bolt, which is arranged in cooperation with coupling A and coupling B and is arranged between the two hexagon socket screws, and is used to further fix coupling A and coupling B.

[0007] Preferably, it also includes: a linkage rubber, which is arranged between the coupling A and the coupling B on both sides, and the coupling A and the coupling B on both sides can be sleeved on the linkage rubber, and the coupling A and the coupling B on one side can drive the coupling A and the coupling B on the other side to rotate through the linkage rubber.

[0008] Beneficial effect: The utility model provides a water jet loom hem coupling, which is optimized for this drawback, effectively solving the previous cumbersome and complicated replacement steps, reducing the original cumbersome replacement process, simplifying the process and ensuring the original adjustment accuracy, and can be easily replaced without changing the position of other installed parts.
