Automatic roll changing machine for plastic film

Abstract

The invention provides an automatic roll changing machine for a plastic film. A cutting knife assembly, a pressing arm assembly, a material preparation assembly, a secondary wheel assembly, a roll pressing assembly and a roll arm assembly are sequentially arranged between side plates from back to front. A transmission roller is in rotating shaft connection to the middle positions in the side plates. The material preparation assembly comprises a paper roller and a sleeve; and the sleeve is fixed to the inner walls of the side plates through bolts, the paper roller is arranged on the upper portion of the sleeve, and the roll pressing assembly comprises a third air cylinder and a pressing arm. The third air cylinder is fixed to the outer wall of one side plate through bolts, a pressing arm is in rotating shaft connection to the outer wall of one side plate, the third air cylinder is connected with the pressing arm, and the roll arm assembly comprises a fourth air cylinder and a roll arm. The fourth air cylinder is fixed to the inner wall of one side plate through bolts, a roll arm is in rotating shaft connection to the inner wall of one side plate, and the fourth air cylinder is connected with the roll arm. The secondary wheel assembly can automatically cut the plastic film and wind the film on the upper portion of a new paper tube, and therefore automatic roll changing of the plastic film is achieved.

Description

technical field [0001] The invention relates to the technical field of roll changing machines, in particular to an automatic roll changing machine for plastic film. Background technique [0002] In the prior art, the roll changing machine needs to be manually operated, and the roll changing operation is performed by attaching tape to the paper tube. However, this method leads to extremely low processing efficiency, seriously reduces production efficiency, and makes the production cost higher. . Contents of the invention [0003] The problem to be solved by the invention is how to realize the automatic roll changing of the plastic film.
