AI Technical Summary

Problems solved by technology

If during the weaving process, some springs swing and cross together or break due to resonance, it is very troublesome to stop the machine to replace the springs or handle the springs in various parts, which directly affects the working efficiency of the loom

Embodiment Construction

[0017] like figure 1 As shown, the upper section of the helical spring 6 used for the jacquard loom is the main section 9, and the main section is operated by pulling the jacquard. Below the main body section 9 is a small-diameter helical section 10 with very tight helical threads. The so-called very close helical thread means that the helical threads are closely attached to each other and have a relatively large pre-tightening force. Below the small-diameter helical section 10 is a helical section 11 with a certain interval between every two helixes, and works through compression. Because there is a certain distance between every two helixes, it is like a shock absorber. It is used for cushioning and reducing the elastic force of the spring due to the high-speed operation of the loom. The so-called certain interval means that there is an interval distance that can be distinguished with the naked eye between the spirals of the spring. The diameter of each helix of the main b...

Abstract

This invention relates to a whirl spring and circle bar and harness cord used in hook loom, wherein, the upper section of spring is main one and the down part is spring section with small diameter with one spring sections. The circle bar is composed of top swing proof section and middle buffer section and down connection section and the swing proof section down part has one spring section and theconnection section has one connection hole. The circle swing proof section is inserted into the main section from the spring section and the section with small diameter is set in the screw section toform one harness cord.

Description

technical field [0001] The invention belongs to a helical spring for a jacquard loom, a return heald bar and a harness composed of the helical spring and the return heald bar. Background technique [0002] Weavers all know that when using a loom with a jacquard device to produce fabrics, it is necessary to connect the jacquard part with the loom through installation according to the requirements of the type of fabric produced, so the up and down alternate movements of the installation form a fabric. kind of. The alternating movement is performed by two commands, raising and lowering. The raising movement is determined by the suspended jacquard part, while the opposite operation, the lowering of the assembly, can be determined by different devices. Under the effect of the gravity of the earth, it used to be used on looms with a speed lower than 150 / 180 rpm, using elastic ropes, and then springs. Even with springs, as the speed of the loom increases to 1200 / 1400 RPM, it will...
