Description

Technical Field

[0001] The utility model belongs to the technical field of cloth guiding and conveying, and relates to a tension regulating device. Background Art

[0002] Grey fabric conveying refers to the process of conveying grey fabric (i.e. raw fabric that has not been dyed or otherwise processed) from one place to another in the textile, printing and dyeing or other related industries. This process usually involves the use of professional conveying equipment or systems to ensure that the grey fabric can be conveyed to the designated location smoothly and accurately. During the conveying process, the adjustment of the fabric tension is very important. If the tension cannot be effectively adjusted, a series of problems will arise, which will seriously affect the quality and production efficiency of the fabric.

[0003] When the tension of the fabric is unstable during the feeding process, the fabric is prone to wrinkles. This is because the tension difference in different areas of the fabric makes it impossible for the fabric to remain flat. Wrinkles not only affect the appearance of the fabric, but may also affect the smooth progress of subsequent processing steps.

[0004] Unstable tension may also cause the fabric to stretch or shrink during the feeding process. If the tension is too high, the fabric may be overstretched, resulting in inaccurate size; if the tension is too low, the fabric may shrink, resulting in a smaller size. This size change is extremely disadvantageous for fabric products that require precise size control. Therefore, a tension adjustment device is urgently needed to solve the above problems.
