When the heat shrink knife 21 needs to be polished and cleaned, the pull rod 17 can be pulled to make the fixed block 16 withdraw from the inside of the fixed groove 20, and then the heat shrink knife 21 is pulled downward to remove the heat shrink knife 21 from the inside of the mounting seat 12, so that it is convenient for the staff to polish and clean the heat shrink knife 21. After the heat shrink knife 21 is cleaned, the heat shrink knife 21 can be inserted into the inside of the mounting seat 12 again, and then the fixed block 16 is pushed to make the fixed block 16 enter the inside of the fixed groove 20 to fix the heat shrink knife 21.
[0036] A spring 19 is wrapped around the outside of multiple pull rods 17, one end of multiple springs 19 is fixedly connected to one side of the inner wall of the installation groove 18, and the other end of multiple springs 19 is fixedly connected to one side of the fixed block 16. When the heat shrink knife 21 enters the inside of the mounting seat 12, the pull rod 17 can be loosened and the spring 19 can be used to push the fixed block 16 into the fixed groove 20 to fix the heat shrink knife 21.
[0037] A conveyor belt 2 is fixedly connected to one side of the middle part of the rear end of the inner side wall of the chassis 1, and a workbench 15 is fixedly connected to one side of the middle part of the rear end of the inner side wall of the chassis 1. A slot 14 is provided on the top of the workbench 15. The conveyor belt 2 can be used to transport the products that need to be bundled to the top of the workbench 15, and the workbench 15 can be used to place the products that need to be bundled, so as to facilitate the next step of operation. The workbench 15 is tilted to the side away from the conveyor belt 2, so that the products on the workbench 15 can continue to move.
[0038] A connecting rod 24 is rotatably connected to the rear end of the inner wall of the chassis 1, and a feed roller 8 is slidably connected to the outer side of the connecting rod 24. A plurality of guide rollers 9 are rotatably connected to one side of the rear end of the inner wall of the chassis 1. The film wrapped around the feed roller 8 can be pulled by the guide rollers 9, and the film is removed from the outer side of the feed roller 8 and passes through the slot 14 on the workbench 15 and covers the surface of the product on the workbench 15, thereby bundling the product.
[0039] Limiting grooves 22 are provided on both sides of the top and bottom of the inner wall of the feed roller 8, and grooves 23 are provided on both sides of the top and bottom of the connecting rod 24. The inner walls of the two grooves 23 are fixedly connected with springs 25, and the other ends of the two springs 25 are fixedly connected to the limiting blocks 4, and the other ends of the two limiting blocks 4 are slidably connected to the inside of the limiting grooves 22. When the feed roller 8 needs to be replaced, the feed roller 8 can be pulled to one side. When the limiting groove 22 squeezes the limiting block 4 when the feed roller 8 moves, the limiting block 4 retracts, thereby removing the feed roller 8 from the outside of the connecting rod 24. When the feed roller 8 needs to be fixed, the feed roller 8 can be sleeved on the outside of the connecting rod 24, and then the springs 25 can be used to push the limiting block 4 into the limiting groove 22, thereby fixing the feed roller 8 to the outside of the connecting rod 24.
[0040] The limiting groove 22 and the limiting block 4 are both set to be semicircular, and the end of the protrusion that contacts the limiting groove 22 is arc-shaped. When the limiting groove 22 or the inner side wall of the feeding roller 8 squeezes the limiting block 4, the limiting block 4 will be forced to retract into the groove 23.
[0041] Both sides of the front end of the chassis 1 are hinged with a chassis cover 3, and the chassis 1 can be sealed by turning the chassis cover 3 by hand.
[0042] A control box 7 is fixedly connected to one side of the chassis 1, a fixing rod 6 is fixedly connected to one side of the top of the chassis 1, and a warning light 5 is fixedly connected to the top of the fixing rod 6. The control box 7 can be used to control the startup and operation of the electrical components inside the chassis 1. At the same time, the warning light 5 can be used to remind the staff that the electrical components inside the chassis 1 are working to prevent the staff from accidentally opening the box cover 3.
[0043] Working principle: Place the products to be bundled on the top of the conveyor belt 2, and the products can be transported to the top of the workbench 15 through the conveyor belt 2. At this time, multiple guide rollers 9 can pull the film on the outside of the feed roller 8 to move and pass the film through the slot 14 on the workbench 15 to cover the top of the product, and then use the cylinder 10 to push the pressing block 13 to move downward to squeeze the film to expel the air inside the film, and use the electric push rod 11 to push the mounting seat 12 to move downward so that the heat shrink knife 21 can shrink and cut the film; when the heat shrink knife 21 needs to be polished and cleaned, the pull rod 17 can be pulled to make the fixed block 16 withdraw from the fixed groove 20, and then the heat shrink knife 21 can be pulled downward to remove the heat shrink knife 21 from the mounting seat 12, so as to facilitate the staff to polish and clean the heat shrink knife 21. After the heat shrink knife 21 is cleaned, the heat shrink knife 21 can be inserted into the mounting seat 12 again and then the fixed block 16 can be pushed to make the fixed block 16 enter the fixed groove 20 to fix the heat shrink knife 21.
