Threading silk yarn lifting mechanism used on threading silk yarn spring test equipment

Abstract

The invention discloses a threading silk yarn lifting mechanism used on threading silk yarn spring test equipment. The threading silk yarn lifting mechanism comprises a driving belt which is connected with a driving wheel and a plurality of driven wheels, the driving wheel is fixedly connected with a driving shaft, the driven wheels are arranged up and down respectively, the driving belt is divided into a plurality of sections which are arranged in parallel, and a hook clamp is fixedly arranged on each section. According to the threading silk yarn lifting mechanism used on the threading silk yarn spring test equipment, the driving belt is arranged to be a plurality of sections, the hook clamp is fixedly arranged on each section and is used for fixing a threading silk yarn by a joint, the driving wheel on the driving belt is connected with a power mechanism by the driving shaft, the power mechanism drives the driving shaft to move up and down in a reciprocating manner through a crank rocker mechanism, so that the multiple sections of driving belt are staggered up and down to simulate the movement of the spinning of a textile machine so as to drive the threading silk yarn to move up and down, so that the property of a spring can be tested, and the time for obtaining the test result is shortened greatly.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a testing machine for springs on harness wires. Background technique [0002] At present, all kinds of jacquard machines and textile machines have supporting harnesses, which are used to continuously raise and lower the warp during the weaving process. Such as figure 1 , the harness assembly generally includes a harness thread 101, a heald rod 102, a heald 103, and a spring 104. One end of the heald rod 102 is connected to the wire 101, and the other end is connected to the heald 103. The heald 103 is connected to the spring 104, and the heald The rod 102 is provided with a heddle eye 105, and the warp thread used for weaving passes through the heddle eye 105. During the weaving process, the warp thread is continuously lifted and lowered by pulling the harness thread 101. During the lifting and lowering process of the harness thread, The spring 104 connected to the heddle 103 p...

AI Technical Summary

Problems solved by technology

Because the spring is constantly pulled up and back, there are high requirements for the strength of the spring and other indicators. Every time a batch of springs are used, they need to be tested first. Now there is no special equipment for the test of the wire spring. Test by manual means, judged by the experience of technicians, the test time is longer
