Description

Technical Field

[0001] The utility model belongs to the technical field of textile warp knitting machines, and more specifically, relates to an automatic yarn pressing device for a textile warp knitting machine. Background Art

[0002] A warp knitting machine is a type of textile machinery that is mainly used to simultaneously loop one or several groups of parallel yarns on all the working needles of the warp-feeding machine to form a knitted fabric. Automatic yarn pressing refers to the use of automated control systems and mechanical devices on the warp knitting machine to adjust and stabilize the yarn tension to ensure that the yarn maintains appropriate tension during the knitting process, thereby ensuring the quality and stability of the knitted fabric.

[0003] In the prior art, the authorized publication number "CN219280194U" discloses a "compression device for a warp knitting machine"; it includes two brackets, between which a pressing shaft is provided, which is distributed up and down. A plurality of pressing wheels are movably sleeved on the outer walls of the two pressing shafts for compressing the textile yarn on the warp knitting machine. A driving assembly is installed on the inner wall of the two brackets on the side close to each other, for driving the pressing shaft to move. A cleaning assembly is provided on the side where the two pressing shafts are away from each other, for cleaning the fluff on the textile yarn. The utility model compresses the textile yarn on the warp knitting machine by arranging two pressing shafts. When the textile yarn passes through the pressing wheel for compression, some of the fluff on the textile yarn will adhere to the surface of the pressing wheel. The fluff adhered to the surface is scraped off with the help of a brush, thereby realizing automatic cleaning of the pressing wheel. In addition, the staff can rotate the mounting plate to switch the positions of the two brushes, and clean the fluff adhered to the brush without stopping the machine, which is very convenient to use.

[0004] However, the above technical solution often requires manual adjustment of the yarn pressing force during the yarn pressing process, and the entire machine needs to be paused during the adjustment process, making dynamic adjustment impossible. In addition, as the yarn moves along the pressure roller, friction will occur between the yarn and the pressure roller surface, generating an electrostatic effect, causing tiny particles to adhere to the yarn surface. The friction will also cause slight wear of the yarn surface fibers, and the worn fibers will form tiny particles that adhere to the yarn, affecting the subsequent yarn weaving. To this end, our company has proposed an automatic yarn pressing device for textile warp knitting machines to solve the above problems. Utility Model Content
