Description

Technical Field

[0001] The present application relates to the field of cloth tension adjustment, and in particular, to a cloth tension adjustment device. Background Art

[0002] Cloth is an indispensable material in daily life. Traditional rollers used to convey cloth are generally fixedly connected to the frame. However, due to the weight of the cloth itself and the inevitable differences in the rotation speed and size of multiple rollers, the movement speed of each part of the cloth during the conveying process is different, which leads to wrinkles and the inability to maintain good tension. The cloth tension needs to be regulated, which is usually composed of a controllable roller that can be raised and lowered. The tension of the cloth is adjusted by controlling the raising and lowering of the roller to pull the cloth.

[0003] As the working time increases, the long-term friction between the roller used to adjust the fabric tension and the fabric will inevitably cause wear on the outside of the roller, which will in turn affect the working effect of the roller, and the worn roller may damage the fabric during the conveying process. Therefore, the roller needs to be disassembled and replaced regularly. The existing roller and the frame of the adjustment device are mostly connected by a bearing seat and fastened by a shaft end retaining ring fixed with screws to withstand large axial forces at high speeds. However, the disassembly and installation of the roller are correspondingly very cumbersome, and the bearing needs to be regularly lubricated during long-term working. When adding lubricating oil, the roller needs to be disassembled to expose the bearing seat for lubrication. This process requires the device to be shut down, and the lubricating oil cannot be added while the roller is continuously working. To this end, we have designed a fabric tension adjustment device to solve the above problems. Utility Model Content
