Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, and in particular to an automatic material changing device for a labeling machine. Background Technology

[0002] Labeling machines are devices that affix rolls of self-adhesive labels (paper or metal foil) to PCBs, products, or prescribed packaging. They are an indispensable part of modern packaging. As the manufacturing industry moves towards intelligence and automation, companies are demanding increasingly higher levels of automation from their production equipment. As a crucial piece of equipment on the production line, the automatic material changing function of the labeling machine is key to improving production efficiency and achieving automated production. Through automatic material changing devices, labeling machines can seamlessly integrate with other equipment on the production line, enabling continuous production and unmanned operation.

[0003] Existing automatic material changing devices for labeling machines have a certain reserve of roll material. However, when all the reserved roll material is used up, the device can no longer automatically change the roll material, requiring manual replenishment. However, the limit plate cannot be disassembled during manual material changing, making it inconvenient to change the roll material and greatly reducing work efficiency, thus limiting its practicality. Therefore, we propose an automatic material changing device for labeling machines to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide an automatic material changing device for a labeling machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic material changing device for a labeling machine includes: a U-shaped mounting frame, a rotating shaft rotatably mounted inside the U-shaped mounting frame, a rotating disk fixedly mounted on the outer side of the rotating shaft, multiple connecting rods fixedly mounted on one side of the rotating disk, a roll roller rotatably mounted on the outer side of each of the multiple connecting rods, a connecting cylinder slidably sleeved on the outer side of the rotating shaft, a limiting plate fixedly mounted on one side of the connecting cylinder, the limiting plate slidably connected to the outer side of the rotating disk, two T-shaped grooves formed on one side of the limiting plate, T-shaped pressure plates slidably connected in each of the two T-shaped grooves, circular insert rods fixedly mounted on the adjacent sides of the two T-shaped pressure plates, the adjacent ends of the two circular insert rods movably inserted into the interior of the rotating shaft and the connecting cylinder, two screws movably inserted between the two T-shaped pressure plates, nuts threaded to both ends of the two screws, and the adjacent sides of the four nuts movably abutting against the outer side of the corresponding T-shaped pressure plates.

[0007] Preferably, a pull plate is fixedly installed on one side of each of the two T-shaped pressure plates, a guide post is fixedly installed on the inner wall of each of the two T-shaped slides, the ends of the two guide posts that are close to each other are fixedly installed on the outer side of the corresponding T-shaped pressure plate, a return spring is fixedly connected to the inner wall of each of the two T-shaped slides, the ends of the two return springs that are close to each other are fixedly connected to the outer side of the corresponding T-shaped pressure plate, and the two return springs are sleeved on the outer side of the corresponding guide post.

[0008] Preferably, a drive motor is fixedly installed on the top inner side of the U-shaped mounting bracket, and a rotating shaft is fixedly connected to the output end of the drive motor. Two arc-shaped support blocks are fixedly installed on the side wall of the U-shaped mounting bracket. The outer side of the rotating shaft is rotatably installed between the two arc-shaped support blocks. A worm gear segment is fixedly installed on the outer side of the rotating shaft. A worm wheel meshes with the outer side of the worm gear segment. The interior of the worm wheel is fixedly installed on the outer side of the rotating shaft.

[0009] Preferably, two limiting rings are fixedly installed on the outer side of each of the multiple connecting rods, and the two corresponding limiting rings are respectively movably abutting against the two ends of the winding roller.

[0010] Preferably, one side of the limiting plate is provided with multiple insertion slots, and one end of each of the multiple connecting rods is movably inserted into the corresponding insertion slot.

[0011] Preferably, two mounting blocks are fixedly installed on both sides of the U-shaped mounting bracket, and mounting holes are provided in each of the mounting blocks.

[0012] In this utility model, an automatic material changing device for a labeling machine is described. By twisting the nut, the nut is disengaged from the threaded screw, thus removing the nut from the T-shaped pressure plate and the screw. This allows the screw to be pulled out of the T-shaped pressure plate, facilitating its movement. Pulling the pull plate then moves the T-shaped pressure plate along the T-shaped groove, causing the circular insert rod to move along the groove. This further disengages the circular insert rod from the connecting cylinder and the rotating shaft, removing the fixing between the limiting plate and the rotating shaft. Pulling the pull plate again causes the limiting plate to slide along the rotating shaft, disengaging the connecting rod from the insertion slot. This facilitates the disassembly of the limiting plate and the replacement of the roll material on the roll roller, significantly improving work efficiency and broadening its applicability.

[0013] In this utility model, an automatic material changing device for a labeling machine starts by starting a drive motor, which drives the rotating shaft to rotate, which in turn drives the worm gear section to rotate, which in turn drives the worm wheel meshing with the worm gear section to rotate, which in turn drives the rotating shaft to rotate, which in turn drives the rotating disk and the limiting disk to rotate, which in turn drives the connecting rod and the roll roller to rotate, so that when the roll of material on the roll roller is used up, the next roll roller moves to the corresponding position to continue working, thus completing the automatic material changing;

[0014] This utility model has a reasonable structural design. The mutual cooperation between the connecting cylinder, screw, nut, pull plate, T-shaped pressure plate and circular insert rod makes it easy to disassemble the limiting plate, thereby facilitating the replacement of the rolled material on the roll roller, which greatly improves work efficiency and has wider applicability.

Two T-shaped grooves 21 are provided on one side of the limiting plate 12 on the outer side of the rotating disk 7. T-shaped pressure plates 14 are slidably connected in both T-shaped grooves 21. Circular insert rods 17 are fixedly installed on the side of the two T-shaped pressure plates 14 that are close to each other. The ends of the two circular insert rods 17 that are close to each other are movably inserted into the interior of the rotating shaft 6 and the connecting cylinder 13. Two screws 19 are movably inserted between the two T-shaped pressure plates 14. Nuts 20 are threaded to both ends of the two screws 19. The sides of the four nuts 20 that are close to each other are movably abutted against the outer side of the corresponding T-shaped pressure plate 14.

[0023] In this embodiment, a pull plate 18 is fixedly installed on one side of each of the two T-shaped pressure plates 14, and a guide post 15 is fixedly installed on the inner wall of each of the two T-shaped slides 21. The ends of the two guide posts 15 that are close to each other are fixedly installed on the outer side of the corresponding T-shaped pressure plate 14. A return spring 16 is fixedly connected to the inner wall of each of the two T-shaped slides 21. The ends of the two return springs 16 that are close to each other are fixedly connected to the outer side of the corresponding T-shaped pressure plate 14. The two return springs 16 are sleeved on the outer side of the corresponding guide post 15, so that the T-shaped pressure plate 14 remains stable when it moves.

[0024] In this embodiment, a drive motor 2 is fixedly installed on the top inner side of the U-shaped mounting bracket 1. The output end of the drive motor 2 is fixedly connected to a rotating shaft 3. Two arc-shaped support blocks 8 are fixedly installed on the side wall of the U-shaped mounting bracket 1. The outer side of the rotating shaft 3 is rotatably installed between the two arc-shaped support blocks 8. A worm segment 4 is fixedly installed on the outer side of the rotating shaft 3. A worm wheel 5 meshes with the outer side of the worm segment 4. The inner side of the worm wheel 5 is fixedly installed on the outer side of the rotating shaft 6. The worm segment 4 and the worm wheel 5 make the rotating shaft 6 rotate more smoothly.

[0025] In this embodiment, two limiting rings 11 are fixedly installed on the outer side of each of the multiple connecting rods 9. The two limiting rings 11 are respectively movably abutting against the two ends of the winding roller 10 on the side that is close to each other. The limiting rings 11 make the winding roller 10 more stable when it rotates.

[0026] In this embodiment, two mounting blocks 22 are fixedly installed on both sides of the U-shaped mounting frame 1, and mounting holes 23 are opened in the multiple mounting blocks 22. The U-shaped mounting frame 1 can be conveniently installed on the labeling machine through the mounting blocks 22 and mounting holes 23.

[0027] In this embodiment, during use, the outer sides of multiple roll rollers 10 are first covered with roll material. Then, the U-shaped mounting bracket 1 is installed on the labeling machine through the mounting block 22 and mounting hole 23. When automatic material changing is required, the drive motor 2 is started, which drives the rotating shaft 3 to rotate, thereby driving the worm gear section 4 to rotate, which in turn drives the worm wheel 5 meshing with the worm gear section 4 to rotate, which in turn drives the rotating shaft 6 to rotate, thereby driving the rotating disk 7 and the limiting disk 12 to rotate, which in turn drives the connecting rod 9 and the roll rollers 10 to rotate. Thus, when the roll material on the roll roller 10 is used up, the next roll roller 10 moves to the corresponding position to continue working, thereby completing the automatic material changing. When the roll material on all roll rollers 10 is used up, the nut 20 is twisted to disengage the nut 20 from the threaded screw 19, thereby removing the nut 20 from fixing the T-shaped pressure plate 14 and the screw 19. The screw 19 is easily pulled out of the T-shaped pressure plate 14, allowing the T-shaped pressure plate 14 to move. Then, by pulling the pull plate 18, the T-shaped pressure plate 14 begins to move along the T-shaped slide groove 21, which in turn moves the circular insert rod 17 along the T-shaped slide groove 21. This further causes the circular insert rod 17 to disengage from the connecting cylinder 13 and the rotating shaft 6, thus removing the fixing between the limiting plate 12 and the rotating shaft 6. Then, by pulling the pull plate 18, the limiting plate 12 begins to slide along the rotating shaft 6, causing the connecting rod 9 to disengage from the insertion groove 24. This facilitates the disassembly of the limiting plate 12 and the replacement of the rolled material on the winding roller 10, greatly improving work efficiency and broadening its practicality. After the rolled material on the winding roller 10 is replaced on the outside, the above operation is repeated in reverse, causing the connecting rod 9 to re-insert into the insertion groove 24, and the limiting plate 12 and the rotating shaft 6 to be fixed again.
