Description

Technical Field

[0001] The utility model belongs to the technical field of non-woven fabric production, and particularly relates to a non-woven fabric deviation rectifying device. Background Technique

[0002] Non-woven fabric is a kind of fabric formed without the textile process, also known as non-woven fabric or non-woven cloth. It is a new type of fiber product with a soft, breathable and flat structure directly formed by using polymer chips, staple fibers or filaments through a web forming method and a consolidation technology. During the production process of non-woven fabric, in order to avoid deviation of the non-woven fabric during transportation, a deviation rectifying device is usually additionally provided on the conveying device to make the non-woven fabric return to the specified movement track through the deviation rectifying device;

[0003] A deviation rectifying device for an air-jet loom disclosed in the existing document with the publication number CN221117823U includes a support seat and a tension roller. There are multiple groups of tension rollers. A fixing plate is provided between adjacent two groups of tension rollers on the support seat. A sliding groove is provided on the fixing plate. A support plate is slidably provided on the sliding groove. A positioning component is provided on the support plate. The positioning component includes a pushing member provided on the support plate and a pressing plate provided at its top end. A driving plate is slidably provided on the pressing plate along the length direction of the side facing the bottom plate. A driving component is provided on the pressing plate. One end of the driving component is in transmission cooperation with the driving plate;

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. In the above-mentioned deviation rectifying device, a rectangular guiding block is slidably connected to the side wall of the upper end of the support seat along the width direction of the support seat. A limit detector is fixed at the front end of the guiding block. The deviation of the transportation of the non-woven fabric is detected through the limit detector. However, during the use process, the limit detector can only move along the width direction of the support seat. Since the size and thickness of the non-woven fabric are diverse, it can only detect the deviation of non-woven fabrics with the same size and thickness, and the applicability is poor;

[0006] 2. In the above-mentioned deviation rectifying device, the positioning component includes a pushing member and a pressing plate, and a driving plate is arranged on the pressing plate through a driving component. The two ends of the non-woven fabric are clamped by the pressing plate and the driving plate and driven to move, so as to realize the deviation rectification of the non-woven fabric. However, during the use process, although the clamping method can avoid the phenomenon of the edge of the non-woven fabric being folded, it will increase the friction coefficient of the movement of the non-woven fabric, which is not conducive to the transportation of the non-woven fabric.

[0007] Therefore, we provide a non-woven fabric deviation rectifying device to solve the above problems. Content of the Utility Model
