An automatic winding film slitting and rewinding unit

Abstract

The invention belongs to the technical field of rewinding units, specifically an automatic stretch film slitting and rewinding unit, which includes a side support plate, a round rod, a first air expansion shaft, a first butt joint round head, an air motor, an adjustment rod, The first driven roller, the second air shaft, the L-shaped long plate, the second butt round head, the cutting knife for edge material, the pin rod, the rotating strip, the electric push rod, the strip groove plate, the adjusting roller, the electro-hydraulic Push rod and second follower roller. The invention has a reasonable design, which is beneficial to rotate and hold up the film roll to be cut, saves the cumbersome steps of lifting, installing and placing manually or with a spreader, and is conducive to the rapid replacement of the air shaft used for rewinding and the convenient adjustment of the separation. The tension of the cut film roll is convenient for lifting and lowering multiple slit and rewound film rolls at one time, and the rotating strip and the first inflator equipped with the film roll are pulled by starting the electro-hydraulic push rod to run in a contracted state The axis rotates to a vertical state, which is beneficial to rotate and hold up the film roll to be cut.

Description

technical field [0001] The invention belongs to the technical field of rewinding units, in particular to an automatic stretch film slitting and rewinding unit. Background technique [0002] A film is a thin, soft, transparent sheet. Made of plastic, adhesive, rubber or other materials, thin film is scientifically explained as a two-dimensional material formed by depositing atoms, molecules or ions on the surface of a substrate, for example, optical film, composite film, superconducting film, polyester film, nylon film, plastic film, etc. [0003] For some affordable slitting and rewinding units, when rewinding, it is necessary to use a spreader to lift the film roll to be slit on the air shaft and place it on the unit. The operation is cumbersome and inconvenient. The rolled film roll needs to be hoisted and put down immediately due to the small space of the machine unit. It is not convenient to put it in a centralized place and hoist it down at one time, and it will take ...

Problems solved by technology

[0003] For some affordable slitting and rewinding units, when rewinding, it is necessary to use a spreader to lift the film roll to be slit on the air shaft and place it on the unit. The operation is cumbersome and inconvenient. The rolled film roll needs to be hoisted and put down immediately due to the small space of the machine unit. It is not convenient to put it in a centralized place and hoist it down at one time, and it will take a long time. Moreover, the tightness of the film during rewinding will affect the tightening degree of rewinding, such as rewinding loose roll
