Through silk thread installing mechanism on through silk thread spring testing device

Abstract

The invention discloses a through silk thread installing mechanism on a through silk thread spring testing device. A plurality of belt pulleys are fixed on an installation frame and divide a driving belt into a plurality of parallel sections, a fixed hook clamp is fixed on each section of driving belt, a connector hook is fixed on the clamp hook and connected with a fast connector, the fast connector is connected with through silk threads, so that the through silk threads are fixed on the testing device. When the belt pulleys drive the driving belt for driving, no matter the driving belt is in clockwise driving or anticlockwise driving, a part of the hook clamp on the driving belt can ascend, another part of the hook clamp on the driving belt can descend, so that a part of the through silk threads fixed on the clamp hook can ascend, another part of the through silk threads fixed on the clamp hook can descend alternately, accordingly spinning motion of a textile machine can be simulated through vertical reciprocating motion, the performance of a spring can be tested, and the testing time is greatly shortened.

Description

[0001] technical field [0002] The invention relates to the field of textile machinery, in particular to a testing machine for springs on harness wires. Background technique [0003] 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. like 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...

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
