[0061] The working principle of the present invention is as follows:

[0062] When in use, the separation tape is passed through the tape pressing plate and placed on the guide groove body, and at the same time, the film is pulled on the abutment block through the driving roller, and the transmission shaft is driven by the motor to rotate, and the rotation of the driving gear drives the rotation of the driven gear and the driving roller, so that the separation tape moves forward under the friction rotation of the driving roller, and the separation tape is moved and peeled off;

[0063] During this process, the elastic force of the supporting spring is applied to the connecting block, so that the film is located between the abutting block and the limiting roller, and is flattened when the abutting block rotates to prevent wrinkles. When the inclined surface of the abutting block is squeezed by the scraper during the rotation, the abutting block moves downward. When the abutting block moves downward, the pressing block also moves downward, thereby squeezing the first airbag. When the first airbag is squeezed by the pressing block, the gas in the first airbag is transported to the second airbag through the second air pipe. The second airbag expands and pushes the slide plate to move into the slide groove, so that the through groove opens. The heat in the cavity is transferred to the peeling surface of the film through the through groove and the first air pipe, which is beneficial to ensure the toughness of the film and reduce the possibility of the film breaking during the peeling and winding process.

[0064] When the inclined surface of the abutment block is no longer in contact with the scraper, due to the combined elastic force of the reset spring and the support spring, the first airbag and the second airbag are both reset, and the slide plate abuts against the through groove to form a closed structure of the through groove, which is beneficial for the heat in the cavity to be retained therein, thereby achieving smoothness in film peeling and winding, avoiding wrinkling of the film during the peeling and winding process, and ensuring the quality of film peeling.

[0065] When the above-mentioned film separation mechanism is adopted, under the pressure and holding action of the material strip pressure plate, the separation material strip is driven forward by the driving roller, and the wound film is located on the surface of the roller, thereby realizing automatic separation of the film, and the abutment block is driven to rotate by the roller, so that the scraper flattens the film wrinkles on the raised portion, and a deformation space is provided between the recessed portion of the abutment block and the smooth portion of the next abutment block for the film wrinkles to restore to flatness, thereby effectively avoiding the situation where the wrinkles continue to move backward and the film is tightened and deformed, thereby improving the quality of the film, and while the scraper and the front side of the raised portion of the abutment plate are squeezed, the gas in the first airbag is transferred to the second airbag, thereby pushing the slide plate to open the through groove, so that the hot air in the cavity is blown toward the film through the air outlet at the top of the raised portion, and on the basis of smoothing the film, the toughness of the film is improved, thereby effectively avoiding the situation where the film is excessively tightened and caused to break.
