[0041] The working principle and use process of the application are as follows:

[0042] The application is installed on the discharging end of the cutting machine conveying belt 7 of an automatic cutting machine, the suction cup 65 can adsorb the film falling from the cutting machine conveying belt 7 in the rotating process, the air suction interface 69 of the pipe cover 61 is connected with an air pipe, the film storage box 3 is placed in the inside of the discharging supporting plate 12 and is pushed into the inside of the material box embedding groove 14, at this time, the film storage box 3 is positioned in the inside of the collecting groove 11 by the adsorption of the first magnetic block 15 and the second magnetic block 33, then the cylinder 2 drives the film supporting plate 21 to move upwards to the top end, and the film supporting plate 21 in this state is slightly lower than the top end surface of the collecting groove 11.

[0043] The automatic cutting machine works in the feeding and discharging, and drives the cylinder 2 to work. When the cylinder 2 discharges, the PLC controls the servo reducer 4 and the external air suction device to work simultaneously. The output end of the servo reducer 4 drives the main air pipe 6 to rotate on the support seat 1. At this time, the main air pipe 6 also rotates at one end of the pipe cover 61. When the cutting machine conveying belt 7 discharges, a row of suction cups 65 on the main air pipe 6 rotates to the discharging position. The suction cup 65 adsorbs the film about to fall from the cutting machine conveying belt 7, and drives the adsorbed film to rotate upward. When it rotates to be perpendicular to the ground and is located directly below the main air pipe 6, the top plate 66 is separated from the top block 13. During the contact process, the top plate 66 will be displaced downward. The displacement force drives the telescopic pipe 64 and the suction cup 65 to move downward simultaneously. The return spring 67 is stretched. The sealing ring 68 is separated from the sealing between the telescopic sleeve 62. The telescopic pipe 64 is also separated from the extrusion of the one-way sealing gasket 63. At this time, the one-way sealing gasket 63 is not extruded by the telescopic pipe 64, and the telescopic sleeve 62 is closed at the end away from the main air pipe 6. At this time, the front suction cup 65 is not affected by the suction force, and the film originally adsorbed on the suction cup 65 will fall on the upper end of the film supporting plate 21 and in the collecting groove 11. When the film stacking height on the film supporting plate 21 is sensed by the sensor 5, the sensor 5 sends a command. The cylinder 2 drives the film supporting plate 21 to lower the film stacking height. The work continues in this way. When the film falls, the main air pipe 6 rotates under the action of the servo reducer 4, and the top plate 66 gradually separates from the top block 13. Under the action of the return spring 67, the telescopic pipe 64, the suction cup 65, the top plate 66 and the sealing ring 68 are reset simultaneously. The chamfer at one end of the telescopic sleeve 62 also gradually extrudes the one-way sealing gasket 63 to open. At this time, the telescopic sleeve 62 and the telescopic pipe 64 are connected again. The equipment continues to operate, and the work is repeated.

[0044] When the film in the film storage box 3 is full, the film supporting plate 21 has been retracted to the bottom of the cylinder 2. The film is fully stacked in the film storage box 3 and supported by the material supporting frame 32. The film storage box 3 is pulled out by the film pulling handle 31. The first magnetic block 15 and the second magnetic block 33 are separated from the adsorption. The film storage box 3 is moved to the upper side of the discharging supporting plate 12. Then the film storage box 3 is connected with the cut film to take out the film synchronously. Finally, the empty film storage box 3 is replaced to continue the work.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or replace some technical features with equivalent ones.
