The motor 2 drives the anti-slip tray 3 to rotate, and the anti-slip tray 3 can drive the product to be packaged to rotate. The top of the workbench 1 is fixedly connected to a linear module 4, and the output end of the linear module 4 is fixedly connected to a mounting bracket 5. The linear module 4 can drive the mounting bracket 5 to move up and down. The top of the mounting bracket 5 is hinged with a cover pressure plate 6 so that the cover pressure plate 6 can be opened, and the bottom of the cover pressure plate 6 is fixedly connected with a card block 9 so that the cover pressure plate 6 can be closed tightly. The bottom of the mounting bracket 5 is fixedly connected with a column 7, and a stretch film 8 is arranged on the outside of the column 7 for convenient placement of the stretch film 8. The side is fixedly connected to the housing 10, and the inner wall of the housing 10 is fixedly connected to the sliding column 11. The outer periphery of the sliding column 11 is slidably connected to the plug block 12. The outer side of the plug block 12 is fixedly connected to the spring 13. The end of the spring 13 away from the plug block 12 is fixedly connected to the housing 10. The outer side of the plug block 12 is fixedly connected to the rotating frame 14. The internal rotation of the rotating frame 14 is connected to the connecting rod 15. The internal sliding connection of the housing 10 is connected to the button 16. Pressing the button 16 drives the connecting rod 15, which drives the rotating frame 14. The rotating frame 14 drives the plug block 12. The plug block 12 slides on the outer side of the sliding column 11, compressing the spring 13. Release the button 16, and the spring 13 pushes the plug block 12 into the inside of the card block 9. A film cutting assembly is set on the top of the workbench 1 to cut off the excess wrapping film 8. The outer side of the card block 9 is slidably connected to the inside of the mounting frame 5, making it convenient to open and close the cover pressure plate 6. Insert block 12 extends through mounting bracket 5 and is inserted into block 9, preventing block 9 from sliding out and accidentally opening cover plate 6. The outer side of insert block 12 is slidably connected to the interior of housing 10, facilitating insertion into block 9. The end of connecting rod 15, away from rotating bracket 14, is pivotally connected to button 16, which drives connecting rod 15 when pressed.

[0034] Reference Figure 1 and Figure 3 and Figure 5The film cutting assembly includes an assembly frame 17, which is internally fixedly connected to the top of the workbench 1 and other components are installed. The outer side of the assembly frame 17 is fixedly connected to a second motor 18, which drives a bidirectional threaded rod 19 to rotate. The upper and lower ends of the assembly frame 17 are internally rotatably connected to the bidirectional threaded rod 19. The outer periphery of the two ends of the bidirectional threaded rod 19 is threadedly connected to a connecting block 20. The rotation of the bidirectional threaded rod 19 can drive the connecting block 20 to move. A sponge 21 is fixedly connected between the two connecting blocks 20, wherein an electric heating knife 22 is fixedly connected between the two connecting blocks 20. The movement of the connecting block 20 can drive the sponge 21 and the electric heating knife 22 to move. One end of the two bidirectional threaded rods 19 is fixedly connected to a pulley 23, and the two pulleys 23 are connected by a belt. The bidirectional threaded rod 19 connected to the second motor 18 can drive the pulley 23, and the pulley 23 drives the other bidirectional threaded rod 19 to rotate. One end of one of the bidirectional threaded rods 19 away from the pulley 23 is fixedly connected to the output end of the second motor 18, driving the bidirectional threaded rod 19 to rotate. The connecting block 20 is slidably connected to the inside of the assembly frame 17 so that the connecting block 20 can move smoothly.

[0035] Working principle: When in use, press the button 16, the button 16 drives the connecting rod 15, the connecting rod 15 drives the rotating frame 14, the rotating frame 14 drives the plug 12, the plug 12 slides on the outside of the sliding column 11, compresses the spring 13, and the spring 13 generates elastic force. When the plug 12 is driven, it is pulled out from the inside of the block 9, and the cover pressure plate 6 is lifted up. The block 9 slides out from the inside of the mounting frame 5, and the stretch film 8 is placed on the outside of the column 7. The cover pressure plate 6 is lowered, and the block 9 slides into the inside of the mounting frame 5. Release the button 16, and the spring 13 pushes the plug 12 into the block 9 to prevent the block 9 from sliding out and the cover pressure plate 6 from opening accidentally. Place the product to be packaged on the anti-slip tray 3, pass the stretch film 8 between the two sponges 21 and press it on the surface of the product to be packaged, start the motor 2, and the motor 2 drives the anti-slip tray 3 to rotate, etc. After the stretch film 8 is wrapped around for one week, it is loosened and can be automatically wound. The linear module 4 is started, and the linear module 4 drives the mounting frame 5 to move up and down. The mounting frame 5 moves up and down, driving other components installed thereon and the stretch film 8 to move up and down to package the products that need to be packaged. After the packaging is completed, the motor 2 18 is started, and the motor 2 18 drives the bidirectional threaded rod 19, and the bidirectional threaded rod 19 drives the pulley 23. The pulley 23 drives another bidirectional threaded rod 19 to rotate. The two bidirectional threaded rods 19 cooperate with each other to drive the connecting block 20 to move toward the middle. The connecting block 20 drives the sponge 21 and the electric hot knife 22 to move. The sponge 21 first contacts the stretch film 8, and the sponges 21 compress and clamp the stretch film 8. The electric hot knife 22 cuts the stretch film 8 after touching the stretch film 8. The sponge 21 clamps the stretch film 8 to prevent the stretch film 8 from falling to the ground and getting covered with dust or stains.
