Description

Technical Field

[0001] This utility model relates to the field of label winding technology, and more specifically, to a label winding mechanism. Background Technology

[0002] In modern production lines, label winding is a crucial process. In this production environment, frequent replacement and maintenance of label winding rollers are unavoidable. However, existing designs often require operators to spend a considerable amount of time installing and removing the winding rollers, especially when facing mass production or frequent equipment adjustments. Traditional winding roller installation methods are usually cumbersome, requiring specialized tools and procedures. This not only prolongs production line downtime but also increases the labor intensity of operators. Therefore, improving the efficiency of winding roller installation and removal is an urgent problem to be solved.

[0003] Furthermore, with the continuous improvement of production requirements, the flexibility and efficiency of production lines have become particularly important. In some special production tasks, the need for quick replacement of label winding rollers has become more urgent, especially when it is necessary to quickly respond to the winding tasks of different label specifications. Traditional installation and disassembly methods are not flexible enough. Traditional designs often lack simple and quick disassembly and installation mechanisms, which leads to a lot of time wasted when the production line is changing, thus affecting the overall production efficiency.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a label winding mechanism, which has the following advantages:

[0017] 1. The quick-fix mechanism, through a series of precise structural designs, effectively improves the efficiency of winding roller installation and disassembly. The plug-in design between the fixing sleeve and the insert rod allows operators to quickly connect the fixing sleeve and the insert rod, saving installation time. The sliding fit of the sliding sleeve in the sliding groove allows the hinge plate to smoothly push the abutment plate, ensuring stability and accuracy during installation. Through this mechanism, the winding roller can be quickly and firmly fixed on the rotating rod, reducing the complexity of manual operation and lowering the risk of equipment failure. For disassembly operations, the rotation of the rotating sleeve causes the limiting block to slide out of the limiting groove, thereby effectively releasing the restriction of the limiting sleeve. The operation is simple and efficient, improving the working efficiency of the production line.

[0018] 2. The limiting mechanism, through the coordinated operation of multiple sets of limiting sleeves, limiting grooves, rotating sleeves, limiting rods, and limiting blocks, ensures the stability and safety of the winding roller after installation. The limiting sleeves, through the engagement of the limiting grooves with the rotating sleeves, effectively fix the position of the sliding sleeves, preventing loosening or instability of the winding rollers during use. The design of the limiting rods and limiting blocks further enhances the reliability of the structure. The engagement of the limiting blocks with the positioning grooves ensures that the rotating sleeves are firmly positioned, preventing unnecessary loosening or displacement and guaranteeing the safe and stable operation of the winding rollers during production. The push spring provides additional pressure to the positioning block, ensuring positioning accuracy and further enhancing the reliability and long-term stability of the entire system.

[0019] 3. Thrust bearings, positioning holes, and positioning sleeves provide necessary support and protection for the smooth operation of the system. Thrust bearings reduce the friction between the rotating rod and the winding roller, making the installation and disassembly of the winding roller smoother. The precise fit of the positioning holes and positioning blocks makes the positioning more accurate during the insertion and disassembly process, avoiding deviations or instability caused by improper installation. The design of the positioning sleeves and push springs further ensures the precise docking and stability between the components, ensuring the high efficiency of the entire system in actual operation and the stability of long-term use.

The quick-fixing mechanism includes an insert rod 6, a fixing sleeve 7, an abutment plate 8, a hinge plate 9, a sliding groove 10, a sliding sleeve 11, and a limiting mechanism. The insert rod 6 is fixed to the top of the rotating rod 4, the fixing sleeve 7 is inserted into the top of the insert rod 6, the abutment plate 8 is provided with multiple sets rotating inside the fixing sleeve 7, the hinge plate 9 is connected to the bottom of the multiple sets of abutment plates 8, the sliding groove 10 is provided with multiple sets distributed on the outer wall of the fixing sleeve 7, the sliding sleeve 11 slides in the multiple sets of sliding grooves 10 and is rotatably connected to the multiple sets of hinge plates 9, and the outer wall of the insert rod 6 is provided with a slot 30.

[0030] The limiting mechanism includes a limiting sleeve 12, a limiting groove 13, a rotating sleeve 14, a limiting rod 15, and a limiting block 16.

This structure achieves the rapid limiting and stable locking function of the winding roller by using the positioning effect of the limiting sleeve 12 and the limiting groove 13, combined with the rotating sleeve 14 driving the limiting rods 15 and the limiting blocks 16.

[0031] The outer wall of the mounting frame 1 is provided with limiting rollers 17. Multiple sets of limiting rollers 17 are arranged around the mounting frame 1 to prevent the winding roller from shifting axially and improve the safety and stability of the overall operation of the equipment.

[0032] A top block 18 is fixedly provided on the outer wall of the rotating rod 4. Both the outer wall of the top block 18 and the bottom surface of the fixed sleeve 7 are provided with thrust bearings 19. The top block 18 and the thrust bearings 19 work together to reduce the friction between the top block 18 and the fixed sleeve 7 during rotation, so that the rotating rod 4 rotates smoothly and extends its service life.

[0033] The insertion rod 6 is polygonal, and a positioning hole 20 is provided in the fixing sleeve 7. The positioning hole 20 is adapted to the insertion rod 6. The polygonal geometric structure of the insertion rod 6 is precisely matched with the positioning hole 20, which effectively prevents rotation and shaking and enhances the anti-rotation performance of the structural connection.

[0034] The limiting sleeve 12 is provided with a release groove 21. Multiple release grooves 21 are provided on the surface of the limiting sleeve 12 to facilitate the operator to quickly release the limiting state and realize quick disassembly and adjustment operations.

[0035] A positioning sleeve 22 is fixedly provided on the bottom surface of the rotating sleeve 14. A sliding hole 23 is provided on the inner wall of the positioning sleeve 22. Multiple sets of sliding holes 23 are provided, and each set of sliding holes 23 is connected to a push spring 24 on its inner side.

Under the elastic force of the push spring 24, the positioning blocks 25 extend out of the sliding hole 23 and are inserted into the positioning groove 26, realizing automatic reset and precise positioning, so that the rotating sleeve 14 and the fixed sleeve 7 are stably connected.

[0036] The bottom of multiple positioning blocks 25 and the outer side of positioning grooves 26 are all set as arc-shaped positioning blocks 25 and positioning grooves 26. The arc transition structure of positioning blocks 25 and positioning grooves 26 can reduce jamming and wear during the insertion process, making the operation more stable and smooth, and improving the life of components and assembly efficiency.

[0037] In this embodiment, when the winding roller 5 needs to be installed, firstly, a set of thrust bearings 19 are inserted into the outer wall of the rotating rod 4 and abut against the top block 18. Then, the winding roller 5 is inserted into the outer wall of the rotating rod 4. Then, the second set of thrust bearings 19 are inserted into the outer wall of the rotating rod 4 and abut against the outer side of the winding roller 5. Then, the fixing sleeve 7 is inserted into the insertion rod 6, so that the bottom end of the fixing sleeve 7 abuts against the second set of thrust bearings 19. The limiting sleeve 12 is pushed to drive the sliding sleeve 11 to slide along multiple sets of sliding grooves 10 and push the hinge plate 9. The multiple sets of hinge plates 9 push the abutment plate 8 to abut against the slot 30. Then, the rotating sleeve 14 is rotated so that multiple sets of limiting blocks 16 are engaged in the limiting groove 13, thereby supporting and limiting the limiting sleeve 12. The multiple sets of push springs 24 push the positioning block 25 to abut against the positioning groove 26, thereby completing the positioning of the rotating sleeve 14.

[0038] More specifically, when the winding roller 5 needs to be disassembled, the rotating sleeve 14 drives the positioning sleeve 22, which in turn drives multiple positioning blocks 25. Through multiple positioning grooves 26, the positioning blocks 25 are pushed to slide in the sliding hole 23 and squeeze multiple push springs 24. The rotating sleeve 14 drives multiple limiting rods 15 to rotate and causes multiple limiting blocks 16 to slide into the release groove 21, thereby releasing the limitation of the limiting sleeve 12. Then, the limiting sleeve 12 is pushed so that the sliding sleeve 11 pulls multiple hinge plates 9. Through the multiple hinge plates 9, the abutment plate 8 is pulled away from the slot 30, releasing the connection between the fixing sleeve 7 and the insertion rod 6. Then the winding roller 5 and the rotating rod 4 can be disassembled.

[0039] In summary, when the entire equipment is in use or operation: when it is necessary to install the winding roller 5, firstly, a set of thrust bearings 19 are inserted into the outer wall of the rotating rod 4 and abut against the top block 18. Then, the winding roller 5 is inserted into the outer wall of the rotating rod 4. Then, the second set of thrust bearings 19 are inserted into the outer wall of the rotating rod 4 and abut against the outer side of the winding roller 5. Then, the fixing sleeve 7 is inserted into the insertion rod 6, so that the bottom end of the fixing sleeve 7 abuts against the second set of thrust bearings 19. The limiting sleeve 12 is pushed to drive the sliding sleeve 11 to slide along multiple sets of sliding grooves 10 and push the hinge plate 9. Through the multiple sets of hinge plates 9, the abutting plate 8 is pushed into the slot 30. Then, the rotating sleeve 14 is rotated so that multiple sets of limiting blocks 16 are engaged in the limiting groove 13, thereby supporting and limiting the limiting sleeve 12. Through the multiple sets of push springs 24, the positioning block 25 is pushed into the positioning groove 26, thereby completing the positioning of the rotating sleeve 14.

[0040] When it is necessary to disassemble the winding roller 5, the rotating sleeve 14 drives the positioning sleeve 22, which in turn drives multiple sets of positioning blocks 25. Through multiple sets of positioning grooves 26, the positioning blocks 25 are pushed to slide in the sliding hole 23 and squeeze multiple sets of push springs 24. The rotating sleeve 14 drives multiple sets of limit rods 15 to rotate and causes multiple sets of limit blocks 16 to slide into the release groove 21, thereby releasing the limit of the limit sleeve 12. Then, the limit sleeve 12 is pushed so that the sliding sleeve 11 pulls multiple sets of hinge plates 9. Through the multiple sets of hinge plates 9, the abutment plate 8 is pulled away from the slot 30, releasing the connection between the fixing sleeve 7 and the insertion rod 6. Then the winding roller 5 and the rotating rod 4 can be disassembled.
