Description

Tension adjusting assembly of roller press Technical Field The utility model relates to the technical field of roller presses, in particular to a tension adjusting assembly of a roller press. Background In the electrode pole piece rolling process, the tension generated by the pole pieces before and after the roller press is generally larger, so that the tension on the pole pieces is conveniently adjusted, adjusting mechanisms are arranged before and after the roller press, the swinging roller swings in the circumferential direction to adjust the tension, and the tension requirement of the pole pieces entering and exiting the roller press is met. In the adjusting mechanism, the swing arms are driven to swing through rotation of the rotating shaft, so that the swing rollers supported between the swing arms swing in the circumferential direction, and tension adjustment is realized. In order to keep the tension balance of the left end and the right end of the press roller consistent, the axes of the swing roller and the rotating shaft are required to be kept in a parallel state, and deviation cannot be generated, so that the swing roller needs to be regulated, and the axis of the swing roller is regulated by adopting a mode of regulating a swing arm on the non-transmission end side of the rotating shaft at present. The existing connecting structure between the swing arm and the rotating shaft at one side of the non-transmission end of the rotating shaft adopts a tension sleeve to connect the swing arm and the rotating shaft, and is locked by friction force, but when larger tension is encountered, the tension sleeve is easy to wear, the service life is influenced, and the other connecting mode adopts threaded connection and is positioned through a flat key, but the requirement on the machining precision of parts is higher. Disclosure of utility model The utility model aims to solve the technical problem of overcoming the defects in the prior art, and provides the tension adjusting assembly of the roller press, which is convenient to process and has better adjusting effect.
