Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, and more particularly to a chenille yarn tension control device. Background Art

[0002] Chenille yarn, also known as chenille, is a new type of fancy yarn. It can be made into sofa covers, bedspreads, bed blankets, table blankets, carpets, wall coverings, curtains, and more. During the textile process, a tension control device is often required to maintain constant tension in the yarn, ensuring consistency in yarn tension and increasing overall strength. Currently, yarn tension control typically uses a fixed roller. The yarn rubs against the fixed roller, generating a certain amount of tension. Due to long-term friction with the yarn, the fixed roller's surface will wear to varying degrees, requiring regular maintenance of the worn surface. However, due to the large deadweight of the fixed roller, the existing fixing method makes it difficult to rotate the fixed roller, requiring the machine to be shut down for maintenance, significantly reducing production efficiency.

[0003] To address the above-mentioned issues, Chinese patent application number CN210884692U discloses a yarn tension control device comprising a fixed roller, a bearing, a bearing seat, and a pressure plate. The fixed roller is rotatably connected to the bearing seat at both ends via bearings, and the height of the bearing seat is adjustable. The pressure plate is fixedly connected to both ends of the fixed roller and has at least one pressing surface that presses against the bearing seat. This arrangement adjusts the height of the fixed roller to increase or decrease the wrap angle of the yarn. As the wrap angle increases or decreases, the tension of multiple yarns increases or decreases simultaneously, achieving centralized tension control for multiple yarns.

[0004] However, the above solution can only provide a fixed tension, and the yarn will be affected by many factors during the production process, such as temperature, humidity, stretching, etc. These factors may cause the physical properties of the yarn to change. The fixed tension cannot adapt to these changes, causing the yarn to be overstretched or relaxed, which in turn leads to yarn damage, production interruption and other problems.

[0008] The utility model is further configured as follows: a hand wheel is fixedly sleeved on one end of the threaded rod away from the support seat.

[0009] The utility model is further configured as follows: a sliding groove for sliding the fixing rod is opened at the bottom of the adjustment seat, and the outer wall of the fixing rod is fitted with the inner wall of the sliding groove.

[0010] The utility model is further configured as follows: it also includes two fixing plates, the guide wheel is rotatably installed between the two fixing plates, and the support seat is relatively fixedly arranged on the fixing plates.

[0011] The utility model is further configured as follows: a slide rail is provided on the fixed plate, and a slider which is slidably matched with the slide rail is provided on the adjustment seat.

[0012] In summary, the present invention has the following beneficial effects:

[0013] 1.
