Description

Technical Field

[0001] This utility model belongs to the field of loom cam technology and relates to a loom cam multi-arm device. Background Technology

[0002] The loom cam is a crucial component of a loom, primarily responsible for controlling the loom's movement trajectory and speed. A cam is a component with a curved profile or groove, generally used to convert rotary motion into reciprocating linear motion. In a loom, the cam controls various movements, such as the reciprocating motion of the shuttle and the rotation of the warp beam. If the loom cam cannot stably move the sheath beam up and down, it can lead to a series of problems, severely affecting the normal operation of the loom and the quality of the woven fabric.

[0003] The main function of the cam is to control the up-and-down movement of the sheath beam, thereby ensuring the stability of the warp tension and position during the weaving process. If the cam cannot stably control the movement of the sheath beam, the warp tension will change, leading to uneven weaving density, weft skew, weft shrinkage, and other problems, which seriously affect the quality of the fabric.

[0004] The fit between the cam and the sheath beam needs to be very precise. If the cam cannot stably control the movement of the sheath beam, it will lead to increased friction between the two, thus accelerating machine wear. In the long run, this will not only affect the machine's service life but also increase the cost of maintenance and replacement parts. Therefore, there is an urgent need for a cam-driven multi-arm device for looms to solve these problems. Utility Model Content
