Device for preventing conveyed fabric from wrinkling

Abstract

The invention discloses a device for preventing conveyed fabric from winkling, and relates to the field of dyeing and finishing machinery. The device comprises a guide roller and a guide roller shaft connected with the guide roller, wherein a bearing base and a belt wheel are mounted on the guide roller shaft; a bearing is mounted between the bearing base and the guide roller shaft; the belt wheel is mounted on the guide roller shaft through a slide bearing; a limiting base is mounted on the guide roller shaft at the left side of the bearing base; a front friction base is mounted on the guide roller shaft between the bearing base and the belt wheel; a rear friction base is mounted on the guide roller shaft at the right side of the belt wheel; the front friction base and the guide roller shaft are connected in a radial positioning manner and in an axial sliding manner; the rear friction base and the guide roller shaft are connected in the radial positioning manner and in the axial sliding manner; a friction plate is separately arranged on the guide roller shaft between the front friction base and the belt wheel, and on the guide roller shaft between the rear friction base and the belt wheel; and an elastic pressing mechanism is mounted on the guide roller shaft at the right side of the rear friction base. The device is simple in structure, and capable of adapting to the whole dyeing and finishing working condition environment, so that the problem that high-grade fabric has winkles in a conveying process in the prior art is effectively solved, and the product quality and the economic benefits are improved.

Description

technical field [0001] The invention relates to the field of dyeing and finishing machinery, in particular to an anti-wrinkle device for conveying fabrics. Background technique [0002] Dyeing and finishing machinery and equipment need to realize fabric wrinkle-free transmission, high requirements for synchronous transmission, and a wide range of speed regulation. For a dyeing combined machine with a total length of tens of meters, the fabric from cloth feeding to falling cloth needs hundreds of meters to several It is difficult to control the torque difference between the guide rollers to ensure that the fabric transmission devices in all unit machines have the same speed and maintain the balance of fabric tension under different working conditions. [0003] If the linear speed of the front fabric is lower than that of the rear, the fabric will relax and cause wrinkles, which may also cause serious accidents; on the contrary, if the linear speed of the front fabric is too m...

Problems solved by technology

However, processing high-grade fabrics, such as dense, thin, and elastic fabrics, is easy to wrinkle during the process, which is one of the problems that need to be overcome urgently.
