Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Figure 1 This is the overall structural schematic diagram of the present utility model, and in combination with Figures 2 - 5As shown in the figure, the present application includes a bottom plate 1, a first cutting member, a second cutting member, a suction cup 13, and a moving and deflecting assembly 6. On the upper end surface of the bottom plate 1 and in the order of the composite film feeding, a first feeding roller 2, a film cutting table 4, and a second feeding roller 3 are provided in sequence. There are two film cutting tables 4, which respectively cut one side edge of the composite film. A feeding table 7 is fixed in the film cutting table 4. A groove 15 is formed by concave downward on one side of the upper end surface of the feeding table 7 close to the film cutting table 4. The groove 15 makes the feeding table 7 form a cutting reference edge. And a third feeding roller 16 is embedded on the upper end surface of the feeding table 7. The height of the upper end surface of the third feeding roller 16 is equal to the height of the upper end surface of the feeding table 7. A pressing plate 8 is provided above the groove 15. A first electric telescopic rod 5 is installed at the top of the pressing plate 8. The lifting of the pressing plate 8 is realized by using the first electric telescopic rod 5. Both the first cutting member and the second cutting member are arranged on the film cutting table 4. The first cutting member is used for cutting the edge of the composite film. The cutting direction of the second cutting member is perpendicular to the cutting direction of the first cutting member. And the second cutting member is used for cutting the edge of the composite film cut by the first cutting member, so that the longer composite film can be cut, which is beneficial to the subsequent transfer and unloading. The suction cup 13 is used for adsorbing the edge of the composite film cut and dropped on the film cutting table 4. The position of the suction cup 13 is adjusted through the moving and deflecting assembly 6 to realize the adsorption of the cut composite film edge or the guiding of the adsorbed composite film edge away from the film cutting table 4, so as to avoid the accumulation of the cut composite film edge on the film cutting table 4, facilitate the continuous cutting edge operation, and avoid interference.

[0027] Among them, referring to Figure 2 As shown in the figure, the first cutting member includes a second electric telescopic rod 9 and a cutting knife 10. The second electric telescopic rod 9 is installed on the film cutting table 4. The cutting knife 10 is installed at the bottom end of the second electric telescopic rod 9. And the outer wall of the cutting knife 10 fits and lifts along the cutting reference edge. The cutting knife 10 can be moved downward by using the second electric telescopic rod 9. During the feeding process of the composite film, the edge of the composite film can be cut by the edge of the cutting knife 10.

[0028] Referring to Figure 2 As shown in the figure, the second cutting member includes a third electric telescopic rod 11 and a cutter 12. The third electric telescopic rod 11 is installed at one end of the film cutting table 4 close to the composite film inlet. The cutter 12 is installed at the bottom end of the third electric telescopic rod 11. The cutter 12 can be moved downward by using the third electric telescopic rod 11, so as to facilitate the cutter 12 to cut the edge of the longer composite film.

[0029] In the specific implementation manner of the present utility model, referring to Figure 2 and Figure 3 As shown in the figure, the moving and deflecting assembly 6 includes a reciprocating moving part and a deflecting part. The reciprocating moving part is used to realize the linear movement of the suction cup 13. The deflecting part is used to realize the deflection of the adsorption angle of the suction cup 13.

[0030] Specifically, the reciprocating moving part includes a first mounting plate 61 fixed to the film cutting table 4 and a second mounting plate 62 fixed to the bottom plate 1. At the upper end of the outer wall of the second mounting plate 62, a servo motor 63 is installed. The output end of the servo motor 63 is provided with a lead screw 64. An external thread nut seat 65 is arranged outside the lead screw 64, and the other end of the lead screw 64 is connected to the first mounting plate 61 through a bearing;

[0031] The deflection part includes a mounting frame 66 and a deflection motor 67. The mounting frame 66 is fixed to the outside of the external thread nut seat 65. The deflection motor 67 is installed on the mounting frame 66, and the output end of the deflection motor 67 is connected to the suction cup 13 through a rotating shaft.

[0032] Through the above technical solution:

[0033] In specific use, the composite film with the edge to be cut can be fed to the film cutting table 4 through the first guiding roller 2 and finally fed out from the second guiding roller 3. Among them, the first electric telescopic rod 5 can be used to lower the pressing plate 8, and the pressing plate 8 is used to lower the edge of the composite film to be scribed, so that the composite film to be fed is attached to the guiding table 7 provided with the third guiding roller 16 for feeding. Then, the cutting knife 10 is lowered, and the edge of the composite film is cut by the blade of the cutting knife 10. At the same time, the cutting knife 12 can be lowered at regular intervals, which is beneficial for the cutting knife 12 to cut off the longer edge of the composite film.

[0034] While cutting the edge of the composite film, the suction cup 13 can be started. The edge of the composite film on the guiding table 7 is adsorbed by the suction cup 13. The output end of the servo motor 63 can drive the lead screw 64 to rotate, thereby realizing the movement of the external thread nut seat 65, so that the suction cup 13 approaches the guiding table 7 during adsorption and moves away from the guiding table 7 after the adsorption of the suction cup 13 is completed. After moving away from the guiding table 7, the adsorption effect of the suction cup 13 can be released, and the adsorbed edge of the composite film can fall and be collected. Among them, the adsorption angle of the suction cup 13 can be adjusted through the deflection motor 67, which is convenient for better adsorption of the edge of the composite film on the guiding table 7.

[0035] Furthermore, an inclined guide plate 14 is provided on the side of the film cutting table 4 and below the suction cup 13. The edge of the composite film that falls after the adsorption effect of the suction cup 13 is released can slide down along the guide plate 14, reducing the occurrence of scattering onto the bottom plate 1.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
