Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of weftless cloth pressure roller, and relates to a weftless cloth anti-loosening pressure roller device. BACKGROUND

[0002] The existing weftless cloth guiding and conveying pressure roller has the following shortcomings in maintaining pressure on the weftless cloth: uneven pressure distribution, inconsistent pressure roller wear, and damage risk to the weftless cloth. The causes of these shortcomings are usually related to the design, material, and working environment of the pressure roller. The shape, stiffness, and surface treatment of the pressure roller may not be suitable for the physical properties of the weftless cloth, resulting in uneven pressure distribution on the contact surface; at the same time, uneven stress on different parts over a long period of use will cause inconsistent wear, which in turn affects the uniformity of the pressure. In addition, if the material of the pressure roller is too hard or the surface treatment is improper, it may cause unnecessary damage to the weftless cloth.

[0003] The conventional countermeasures include regular maintenance and replacement of the pressure roller, use of surface coating technology to improve the surface properties of the pressure roller, and adjustment of the structural design of the pressure roller to optimize the pressure distribution. However, these methods also have disadvantages. Regular maintenance and replacement can reduce the problem of uneven wear, but will increase production costs and downtime; surface coating technology can reduce damage to the weftless cloth, but the durability and maintenance cost of the coating also need to be considered, so there is an urgent need for a weftless cloth anti-loosening pressure roller device to solve the above problems.
