Description

TECHNICAL FIELD

[0001] The utility model belongs to cloth processing technical field relates to a cloth unwinding machine. BACKGROUND

[0002] In the textile industry, cloth unwinding machine is used to smoothly spread the cloth from the roll and deliver it to the subsequent processing procedure. With the rapid development and technological progress of the textile industry, higher requirements are put forward for the stability and efficiency of the cloth unwinding process to ensure the quality of the cloth is not affected. The traditional cloth unwinding machine is usually composed of a motor-driven unwinding shaft and a series of guide rollers to control the transmission speed and flatness of the cloth from the roll to the production line.

[0003] However, in actual operation, the cloth may wrinkle when rolling due to various factors. For example, uneven tension on different parts of the cloth during rolling may cause excessive folding or relaxation in some areas; changes in environmental conditions such as humidity and temperature may also affect the physical properties of the cloth, making it more prone to wrinkles; in addition, wear and tear of the equipment itself or improper adjustment may also cause abnormal conditions when rolling. Moreover, different materials and thicknesses of cloth have different sensitivities to processing conditions, and some softer or thicker fabrics are particularly prone to wrinkles.

[0004] When these problems occur, the original wrinkles of the cloth may be further compacted due to the pressure after rolling, making the wrinkles more stubborn. Once this compaction effect is formed, even after unwinding, these wrinkles become very obvious and difficult to remove, seriously affecting the appearance quality of the cloth and the subsequent processing effect. The existing cloth unwinding machine can meet the basic needs of cloth unwinding, but it does not have the function of eliminating wrinkles. SUMMARY
