Description

TECHNICAL FIELD

[0001] The utility model relates to adjusting device technical field, especially in a kind of tension roller adjusting device for crimping machine. BACKGROUND

[0002] In the chemical fiber staple fiber post-processing production line, crimping machine is undoubtedly one of the most critical equipment. According to the mechanical crimping principle, the chemical fiber staple fiber in processing is crimped and deformed. Among them, the tension roller plays a key role, which can convert the torque acting on it by the driving device into the strip tension with the friction between the roller surface and the strip. The number and arrangement of tension rollers are not determined at random, but depend on the maximum tensile force required by the strip and the actual conditions of the site and other factors. However, the traditional tension roller equipped with the current crimping machine has many defects, such as inconvenience in adjustment, which greatly limits its adaptability in different production scenarios, resulting in a big discount in practicality.

[0003] As for the existing technical solutions, for example, the Chinese utility model patent with patent number CN 214193579 U discloses a tension roller adjusting device for crimping machine. Although it alleviates some problems of traditional tension rollers to some extent, new problems also come with it. The stability of the device is poor after the tension roller is tensioned, and it is easy to deviate or shake during actual operation, which not only affects the uniformity and stability of the tension, and further affects the crimping quality of the chemical fiber staple fiber, but also more seriously, the device lacks effective buffer mechanism. In the processing of chemical fiber staple fiber, the tension of the strip may change suddenly due to various factors (such as instantaneous impact of the driving device, unevenness of the strip itself, etc.). Without the buffer mechanism to absorb and alleviate these impacts, a large impact force will be generated between the strip and the tension roller, which is easy to cause damage to the chemical fiber staple fiber, reduce the qualified rate of products, increase the production cost, and seriously restrict the improvement of production efficiency and economic benefit.
