Through silk thread spring testing device

Abstract

The invention discloses a through silk thread spring testing device, which comprises a bed body, a motor and a heald return frame. An output end of the motor is connected with a crank and rocker mechanism which is connected with a transmission shaft, the transmission shaft is connected with a belt transmission mechanism, a hook clamp is fixed on a belt of the belt transmission mechanism, a connector hook is fixed on the hook clamp and connected with a fast connector which is connected with through silk threads, the through silk threads sequentially penetrate through a threading hole on a threading plate and an eyehole on a comber board frame and are connected onto a spring under the comber board frame, and the spring is fixed on the heald return frame. The through silk thread spring testing device drives the crank and rocker mechanism to drive the transmission shaft to be in vertical reciprocating motion through the motor, so that spinning motion of a textile machine can be simulated, performance of the spring can be tested, and testing result is greatly shortened. The through silk threads and the spring on the testing device are detachable, so that through silk threads and springs with different types can be replaced for testing.

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
