Description

Technical Field

[0001] This utility model relates to the field of heat shrink film winding technology, and in particular to a trimming and deburring device for heat shrink film winding. Background Technology

[0002] Heat shrink film is a special type of plastic film that shrinks into a shape that fits tightly to an item when heated, thus serving as packaging and protection. After production, heat shrink film needs to be trimmed to cut it into different sizes. After trimming, the edges of the heat shrink film will have burrs, so it needs to be trimmed during winding to remove the burrs, which requires an edge trimming and deburring device.

[0003] For example, the POF heat shrink film trimming device disclosed in Chinese Patent No. CN212197804U works on the principle of "including two parallel cylindrical slide rails, the two ends of which are fixed by a first fixed rod and a second fixed rod respectively. Each slide rail is fitted with a reciprocating slider, and a graduated cylindrical crossbar is connected between the two sliders. Two slidable fixing sleeves are fitted on the crossbar, and each fixing sleeve is provided with a wing screw for fixing the sleeve on the crossbar. Each fixing sleeve has a crescent-shaped cutter on its outer surface. This utility model can meet the needs of trimming defective products, is easy to operate, and will not cut off-center."

[0004] The device uses a cutter to cut and trim the edges of the heat shrink film. However, the cutter wears down gradually during cutting, so it needs to be replaced frequently. The cutter replacement in the above application is cumbersome, resulting in long downtime and affecting production efficiency. In addition, because the cut excess parts are quite small, they are easily blown into the air and scattered everywhere, causing environmental pollution. Therefore, there is an urgent need for a heat shrink film winding edge trimming and deburring device with quick-change cutters. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0006] A heat shrink film winding edge trimming and deburring device includes a base, a fixed frame at one upper end of the base, and sliding grooves at both ends of the fixed frame. A rotating rod is arranged in the sliding groove, a fixed ring is arranged on the outer side of the middle part of the rotating rod, and a cylinder output end is arranged at the top of the fixed ring. A first motor is arranged at one end of the rotating rod, and moving blocks are threaded to the outer sides of both ends of the rotating rod. A connecting block is arranged at the bottom of the moving block, and a limit component is arranged in the connecting block.

[0007] As an improvement to the above technical solution, the limiting component includes a fixing block disposed on the outside of the connecting block, a rotating shaft disposed inside the fixing block, an extension block disposed on the outside of the rotating shaft, a rotating ring disposed on one side of the extension block, a fixing bolt disposed on the other end of the rotating ring, a rotating component rotatably connected to one side of the extension block, and the other end of the rotating component rotatably connected to one end of the limiting rod, and symmetrical slots are provided on the outside of the limiting rod.

[0008] As an improvement to the above technical solution, a limiting block is provided inside the connecting block, and a limiting groove adapted to the limiting rod is symmetrically opened on the outer side of the limiting block. A connecting member is provided at the bottom of the limiting block, and a tool holder is provided at the bottom of the connecting member.

[0009] As an improvement to the above technical solution, a second motor is provided on one side of the tool holder, and a cutting blade is provided at the output end of the second motor, which is located inside the tool holder.

[0010] As an improvement to the above technical solution, the top of the base is symmetrically provided with slots, an electrostatic generator is provided in the slots, an inner groove is provided below the slots, an air intake fan is provided on one side of the inner groove, a drawer is provided at the bottom of the inner groove, and a handle is provided at the outer end of the drawer.

[0011] As an improvement to the above technical solution, limit rollers are symmetrically arranged above the base.

[0012] As an improvement to the above technical solution, a collecting roller is provided at the other end of the base, and a third motor is provided at the other end of the collecting roller.

[0013] The beneficial effects of this utility model are:

[0014] By rotating and loosening the fixing bolts, the rotating ring is separated from the connecting block. Then, the rotating ring, together with the extension block, rotates around the axis. When the rotating ring and the extension block rotate together, they will drive the rotating component connected to the extension block to rotate as well. When the rotating component moves, it will drive the limiting rod connected to it to move within the connecting block. When the rotating component is rotated, its direction of movement will become oblique, thereby increasing its movement distance. This makes it easier to drive the limiting rod connected to its other end to move further, thus facilitating the insertion of the limiting block into the connecting block. The upper and lower parts of the limiting groove on the limiting block are respectively adapted to the slot on the limiting rod and the limiting rod itself. When the limiting rod is pulled outward, it is inserted upward into the limiting block. The upper part of the limiting groove is adapted to the slot, so that the limiting groove can be fully connected to the limiting rod. Then, the limiting rod is pushed inward, so that the thicker part of the limiting rod fits against the lower part of the limiting groove, thereby achieving a tight connection and limiting fixation effect.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please refer to Figures 1-4 A heat shrink film winding edge trimming and deburring device includes a base 1, a fixed frame 3 is provided at one upper end of the base 1, and both ends of the fixed frame 3 are provided with sliding grooves 8. A rotating rod 6 is provided in the sliding grooves 8. A fixed ring 5 is provided on the outer side of the middle part of the rotating rod 6. The output end of a cylinder 4 is provided at the top of the fixed ring 5. A first motor 9 is provided at one end of the rotating rod 6. Moving blocks 7 are threadedly connected to the outer sides of both ends of the rotating rod 6. A connecting block 10 is provided at the bottom of the moving block 7. A limit component is provided in the connecting block 10.

[0022] Specifically, the cylinder 4 drives the fixed ring 5 and the rotating rod 6 connected to it to move up and down in the slide groove 8 within the fixed frame 3. The slide groove 8 at one end of the fixed frame 3 is shallow, just enough to allow the rotating rod 6 to slide inside. The slide groove 8 at the other end of the fixed frame 3 extends through the fixed frame 3 to allow the rotating rod 6 to be exposed and connected to the first motor 9. At the same time, the threaded parts on the outer sides of both ends of the rotating rod 6 are not integral with the rotating rod 6. The first motor 9 can drive the threaded parts to rotate and drive the moving block 7 on its outer side to move through the threaded connection, thereby adapting to different cutting requirements. At the same time, the up and down adjustment by the cylinder 4 can also reduce the wear of the tool and adjust the distance between the tool and the heat shrink film to achieve a better cutting effect.

[0023] Please refer to Figures 1-4 The limiting component includes a fixing block 24 disposed on the outside of the connecting block 10, a rotating shaft 25 disposed inside the fixing block 24, an extension block 31 disposed on the outside of the rotating shaft 25, a rotating ring 22 disposed on one side of the extension block 31, a fixing bolt 23 disposed on the other end of the rotating ring 22, a rotating component 32 rotatably connected to one side of the extension block 31, and the other end of the rotating component 32 rotatably connected to one end of the limiting rod 26, a slot 30 symmetrically opened on the outside of the limiting rod 26, a limiting block 28 disposed inside the connecting block 10, a limiting groove 29 symmetrically opened on the outside of the limiting block 28 to match the limiting rod 26, a connecting component 27 disposed at the bottom of the limiting block 28, and a tool holder 11 disposed at the bottom of the connecting component 27.

[0024] Specifically, the rotating ring 22 is separated from the connecting block 10 by loosening the fixing bolt 23 by rotating it. Then, the rotating ring 22, together with the extension block 31, rotates around the rotating shaft 25. When the rotating ring 22 and the extension block 31 rotate together, they will drive the rotating component 32 connected to the extension block 31 to rotate together. When the rotating component 32 moves, it will drive the limiting rod 26 connected to it to move within the connecting block 10. When the rotating component 32 is driven to rotate, its direction of movement will become oblique, thereby increasing its movement distance and facilitating the movement of the limiting rod 26 connected to its other end. The positioning rod 26 moves further, making it easier to insert the limiting block 28 into the connecting block 10. The upper and lower parts of the limiting groove 29 on the limiting block 28 are respectively adapted to the slot 30 on the limiting rod 26 and the limiting rod 26. When the limiting rod 26 is pulled outward, it is inserted upward into the limiting block 28. The upper part of the limiting groove 29 is adapted to the slot 30, so that the limiting groove 29 can be completely connected with the limiting rod 26. Then, the limiting rod 26 is pushed inward, so that the thicker part of the limiting rod 26 fits against the lower part of the limiting groove 29, thereby achieving a tight connection and limiting fixation effect.

[0025] Please refer to Figures 1-4 A second motor 13 is provided on one side of the tool holder 11, and a cutter 12 is provided at the output end of the second motor 13. The cutter 12 is located inside the tool holder 11.

[0026] Specifically, the position of the cutter 12 is adjusted by controlling the movement of the cutter holder 11, and the cutter 12 is rotated by the second motor 13 to facilitate edge trimming.

[0027] Please refer to Figures 1-4 The top of the base 1 is symmetrically provided with slots 17, and an electrostatic generator 18 is provided in the slots 17. The bottom of the slots 17 is provided with an inner groove 19, and an air intake fan 20 is provided on one side of the inner groove 19. A drawer 21 is provided at the bottom of the inner groove 19, and a handle 16 is provided at the outer end of the drawer 21.

[0028] Specifically, the suction fan 20 generates suction to draw the scrap edges of the heat-shrink film through the slot 17 into the drawer 21 inside the inner slot 19. When the scrap edges pass through the static electricity generator 18 inside the slot 17, they will be charged with static electricity, making them easier to be attracted away and improving the absorption efficiency. This is existing technology and will not be described in detail. The handle 16 is used to push and pull the drawer 21 to recycle the scrap edges inside.

[0029] Please refer to Figures 1-4 Limiting rollers 2 are symmetrically arranged above the base 1.

[0030] Specifically, the position of the heat shrink film is adjusted by the limiting roller 2, which facilitates trimming during collection.

[0031] Please refer to Figures 1-4 A collecting roller 15 is provided at the other end of the base 1, and a third motor 14 is provided at the other end of the collecting roller 15.

[0032] Specifically, the third motor 14 drives the collecting roller 15 to rotate, thereby collecting the trimmed heat shrink film for subsequent use. The collecting roller 15, the limiting roller 2, and the fixing frame 3 are all externally fixed, but are not shown in the figure for ease of illustration.

[0033] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
