Problems solved by technology

Therefore, people have developed various warping machine tension controllers, such as the warping machine tension controllers of Chinese patents ZL91229567.8, ZL94247535.9 and ZL97247379.3, all of which belong to mechanical single yarn tension controllers. The tension of the yarns must be adjusted one by one, which is extremely inconvenient and may not be adjusted properly due to human reasons
In addition, this type of tension controller has a limited adjustment range and cannot fully compensate for tension changes due to the process of changing the yarn bobbin from large to small.

Abstract

An automatic tension adjusting device of a warping machine is provided. The invention includes a bracket, on which a top roller is arranged; the top roller is connected with the bracket; an oscillating arm rotating around a top roller spindle is arranged on the bracket; a bottom roller is arranged on the oscillating arm and is movably connected with the oscillating arm via the bottom roller spindle. The automatic tension adjusting device further comprises an oscillating arm driving mechanism which can drive the oscillating arm to rotate around the top roller spindle. The automatic tension adjusting device has the advantages of convenient adjustment, rapid response, high accuracy of regulation, and can ensure the consistent length, number of turns and length of turns for the pan heads in the same group; thereby the warping quality can be greatly improved.

Description

technical field [0001] The invention relates to an automatic tension adjustment device, in particular to an automatic tension adjustment device for a warping machine. Background technique [0002] Warping is a very important preparation process before weaving. The warping tension directly affects the smoothness of the warp knitted fabric surface. Therefore, it is necessary to ensure that the yarn tension on each pan head on the same shuttle is basically the same. Therefore, people have developed various warping machine tension controllers, such as the warping machine tension controllers of Chinese patents ZL91229567.8, ZL94247535.9 and ZL97247379.3, all of which belong to mechanical single yarn tension controllers. The sheet yarn tension must be adjusted separately one by one, which is extremely inconvenient, and the adjustment will not be in place due to human reasons. In addition, this type of tension controller has a limited adjustment range and cannot fully compensate f...
