The second step is that: loading a double-layer cylinder film: the workman will be equipped with the blowing roller 24 that is equipped with double-deck section of thick bamboo membrane and install on pivot 22, then cut the one end of double-deck section of thick bamboo membrane into two plastic film, and will cut two plastic film winding of accomplishing through the workman and receive on material roller 35, open drive motor 23 this moment, drive motor 23 drives pivot 22 clockwise rotation, make pivot 22 drive blowing roller 24 carry out clockwise rotation, so that cut unit 3 and roll in succession to double-deck section of thick bamboo membrane and cut the processing, thereby improve and cut efficiency, reduce workman's work load, start this moment and cut unit 3.
The third step: cutting the double-layer cylindrical film: when the double-layer cylinder film passes through the Contraband template 371, the protective roller 375 can prevent the double-layer cylinder film from being scratched with the Contraband template 371, so that the double-layer cylinder film is prevented from being damaged, the air pump 372 is opened at the moment, the upper end and the lower end of the front side and the upper end and the lower end of the rear side of the double-layer cylinder film can be respectively adsorbed by the air pump 372, the double-layer cylinder film is in an open shape, the protective sponge 376 can isolate the double-layer cylinder film from the Contraband template 371 during the period, the double-layer cylinder film can be prevented from being rubbed with the Contraband template 371, and the double-layer cylinder film can be prevented from being adsorbed into the execution hole 374, so that the protective effect on the double-layer cylinder film is achieved, and the plastic film is prevented from being damaged during cutting; at the moment, the bidirectional motor 31 is turned on, the bidirectional motor 31 drives the linkage shaft 33 to rotate through belt transmission, so that the linkage shaft 33 drives the cutting blade 34 to synchronously roll and cut the front side and the rear side of the double-layer cylindrical film, when the cutting blade 34 rotates, the auxiliary belt 384 abuts against the cutting blade 34 under the action of the telescopic spring rod 381 matched with the execution block 382, so that the auxiliary belt 384 and the cutting blade 34 generate friction force, and further the auxiliary belt 384 and the cutting blade 34 rotate in opposite directions under the action of the connecting shaft 383, so that the double-layer cylindrical film is abutted against the cutting groove 385 to guide the double-layer cylindrical film, so that the cutting blade 34 continuously rolls and cuts the double-layer cylindrical film, thereby the straightness of the cut part of the plastic film can be ensured, the double-layer cylindrical film is rolled and cut into two plastic films, and at the moment, the roll-cut plastic film and the linkage shaft 33 can be prevented from being scratched through the protective balls, thereby avoiding damage to the plastic film.
The fourth step: and (3) rolling a plastic film: the receipts material roller 35 of upside carries out clockwise rotation under the effect of blowing roller 24, and will drive the receipts material roller 35 of downside through linkage gear 36 and carry out anticlockwise rotation, be convenient for carry out synchronous rolling processing with the plastic film that the hobbing was accomplished, thereby can raise the efficiency, during support spring pole 352 can support squeeze roll 353 and lean on in receipts material roller 35 outer wall, and then extrude spacingly to the plastic film on receiving material roller 35, prevent that the plastic film from appearing scattering, improve the roughness of plastic film rolling.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
