Description

Technical Field

[0001] The utility model relates to the technical field of textile, in particular to a wire-passing tension elastic device for textile machinery. Background Technique

[0002] The spinning on textile machinery needs to pass through a wire-passing tension mechanism, and the wire-passing tension mechanism has a number of tension springs. The thicknesses of the existing tension springs on textile machinery are the same, and the diameter of the tension spring is 3.0 mm. Through practice, it is found that when producing most products, the too large diameter of the tension spring makes it difficult for the wire-passing tension mechanism to press down when the yarn passes through, resulting in an ideal elastic force. When generating the elastic force, the too thick tension spring will generate a large vibration amplitude, resulting in large fluctuations, and further making the tension of the product uneven. A wire-passing tension mechanism for textile machinery with the application number 201920560967.3 includes a bracket, a first wire-passing tension unit... and can produce an ideal elastic force, with a small vibration amplitude, small fluctuations, and uniform tension of the product. However, when installing this device, it is necessary to rotate screws and insert the support part into the installation groove, the installation is not convenient enough, and it is not stable enough to fix one end of the elastic support component through the support part and the installation groove.

Slots with horizontal bottoms are opened on the inner side wall of the installation groove 3, and installation blocks 5 are inserted into the slots. An elastic support assembly 2 is fixedly arranged between a pair of installation blocks 5 corresponding to a pair of installation cross beams 1. Positioning holes 12 are opened on the upper end surface of the installation block 5. The bottom of the installation cross beam 1 is provided with a bottom plate 11 slidably through a limiting device, and a positioning column 7 and a pressing device are fixedly arranged on the top of the bottom plate 11. The positioning column 7 penetrates through the installation cross beam 1 and is inserted into the positioning hole 12.
