Description

Technical Field

[0001] The utility model relates to the technical field of material blanking, in particular to a cast film material blanking device. Background Art

[0002] Cast film is a non-stretched, non-directional flat extruded film produced by melt casting and quenching. The plastic film prepared by the casting method is cooled and shaped on a cooling roller, and then the product is rolled up after traction and trimming. When unloading the finished film roll, it is usually necessary to manually carry it down. During the up and down transportation process, it may collide with the device, causing scratches on the film, and it is also time-consuming and labor-intensive to carry it up and down.

[0003] A search was conducted on the above-mentioned issues and it was found that in the currently disclosed prior art, there is a film winding machine that is convenient for unloading, such as the one proposed in publication number CN217971812U. The device places the winding roller on a telescopic cylinder and connects it to a reciprocating screw through the telescopic cylinder. After the film is wound up, the reciprocating screw is moved to drive the winding roller to move to the material receiving rack. Then, the telescopic cylinder is compressed to place the winding roller on the material receiving rack. Then, the winding roller is manually pulled out to leave the film on the material receiving rack. However, when the winding roller is manually pulled out, if the film is wrapped tightly around the winding roller, it may cause difficulty in unwinding. If the film is wrapped loosely, the film may be misplaced during unwinding, thereby affecting the film winding and unloading effects. Utility Model Content
