Description

A sisal fiber shearing machine that prevents twisting of wires after wire breakage

technical field

The invention relates to the technical field of special equipment for shearing sisal fiber, in particular to a shearing machine for sisal fiber that prevents strands from being twisted after breaking.

Background technique

During the production process of sisal rugs, the sisal hemp is finally woven into carpets by looms. Because the texture of sisal fiber is relatively hard and tough, and the uniformity of sisal fiber is very poor, the surface of sisal fiber is very rough, and there are many miscellaneous fibers forming hairiness, so before sisal fiber can be used for weaving, it must be The sisal fiber is sheared to make the surface of the sisal smoother, which facilitates the weaving of the sisal.

The shearing machine applied by the applicant can trim the hairiness on the surface of the sisal fiber, but in the building process, because the thickness uniformity of the sisal fiber is poor, when trimming to the position of the thinner sisal fiber, It is very likely to cause the sisal fiber to break, and the broken end of the sisal fiber after the broken line, wherein the broken end of one end connected with the receiving device is taken up by the inertia energy under the automatic shutdown of the receiving device, but with The broken end connected to the discharging device will continue to discharge under the action of inertia. Although the broken end connected to the discharging device will not continue to be transported forward at the original speed due to the loss of tension of the sisal fiber, the broken end It will also be in the area of the shearing device for a long time, causing the shearing device to wind the broken end connected with the feeding device on the shearing device, or even directly twist it; It will still be transported forward under the action, but the broken end will also be drawn into the shearing device or even twisted during the transport process. After winding to the shearing device, the operator needs to spend a lot of time to sort out the broken ends after stopping the machine; if the sisal fiber is directly twisted by the shearing device, it is not only difficult to take out the twisted sisal fiber, but also causes the shearing machine to be broken during the process. It will receive resistance, increase energy consumption, and also damage the shearing machine, and also cause waste of sisal fiber.
