Description

Technical Field

[0001] This utility model relates to the field of packaging material production technology, specifically a winding device suitable for packaging material production. Background Technology

[0002] On a continuous production line for packaging materials, the winding process is a crucial step. The finished packaging materials need to be neatly and tightly wound onto the winding rollers to facilitate subsequent transportation, storage, and processing.

[0003] In existing technologies, once a roll of material is wound up, the machine must be stopped for replacement. Operators need to manually remove the fully loaded take-up roller and install a new empty take-up roller. This process involves multiple steps, including braking, disassembly, handling, installation, and repositioning of the equipment, which is time-consuming. The production line is forced to stop during this period, resulting in wasted capacity and energy loss. After replacing the take-up roller, workers need to manually pull the material end to the new roller position and fix it by means of tape, pressure strips, or inserting it into the slot. This process is not only cumbersome and time-consuming, but also prolongs downtime. Furthermore, manual operation makes it difficult to ensure that the material end is absolutely flat, secure, and precisely fixed on the roller surface. Uneven or misaligned end fixation can easily lead to uneven winding of the initial layers, affecting the overall roll quality and potentially causing material breakage or deviation during subsequent winding processes.

A second adjusting rod is slidably installed inside the first adjusting rod. A fixed rod is provided on the rotating frame. The fixed rod is movably engaged with the second adjusting rod. Multiple sets of vacuum suction cups are provided inside the fixed rod. The multiple sets of vacuum suction cups are connected in parallel through connecting pipes. Installation grooves are opened on the two sets of winding rollers. The installation grooves are correspondingly set with the fixed rods. The fixed rods can be engaged with the winding rollers through the installation grooves.

[0007] As a further preferred embodiment of this technical solution, two sets of bidirectional lead screws are rotatably installed inside the mounting frame. The bidirectional lead screws are correspondingly arranged with the two sets of movable frames, and the two ends of the bidirectional lead screws pass through the two sets of movable frames and are threadedly connected to the two sets of movable frames respectively.

[0008] As a further preferred embodiment of this technical solution, a threaded rod is rotatably installed inside the mounting rod, the lower end of the threaded rod passes through the first adjusting rod and is threadedly connected to the first adjusting rod, and a threaded tube is rotatably installed inside the first adjusting rod, the lower end of the threaded tube passes through the second adjusting rod and is threadedly connected to the second adjusting rod.

[0010] As a further preferred embodiment of this technical solution, two sets of symmetrically distributed slides are slidably installed inside the second adjusting rod. Each set of slides has a fixed insert rod, which is movably engaged with a fixed rod.

During operation, the fixed rod can be accurately inserted into the mounting groove of the new winding roller for locking and positioning. The motor on the moving frame drives the winding roller and the motor on the base drives the rotating frame, so that the rotating frame and the winding roller on the same axis can rotate together to efficiently complete the winding of the packaging material. After winding is completed, the locking between the fixed rod and the second adjusting rod can be quickly released by the operation handle linked to the gear rack mechanism, and the external air source can be turned off to release the material end of the vacuum suction cup. The fixed rod can then be easily pulled out from the second adjusting rod and the mounting groove.

[0014] (2) This utility model, through a multi-stage telescopic structure of the mounting rod, the first adjusting rod, and the second adjusting rod, enables precise and stable adjustment of the working height of the fixed rod. When the vacuum adsorption function is not activated, the fixed rod can be adjusted to an appropriate height so that it lightly presses against the surface of the rotating take-up roller. This effectively smooths the packaging material being wound, prevents the material from wrinkling or loosening, and significantly improves the flatness and compactness of the entire roll of material. When a roll of material is finished being wound, the air source can be immediately activated to allow the vacuum suction cup to adsorb the end of the material. Workers can then perform neat cutting in this state. Subsequently, using the height adjustment function, the fixed rod with the new end adsorbed can be easily and accurately positioned and inserted into the mounting groove of the next set of empty take-up rollers, ensuring that the end of the material is flat, firm, and precisely fixed in position, laying the foundation for high-quality winding of the next roll. This function greatly simplifies the roll changing and connection operation, ensures the flatness of the starting section of winding, and effectively reduces quality problems caused by poor end fixing.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figures 1-7As shown in this embodiment, a winding device suitable for packaging material production includes a base 1 and a winding roller 12. A mounting frame 2 and a rotating frame 3 are rotatably mounted on the base 1. The mounting frame 2 is rotatably connected to the base 1 via a mounting shaft 4. A gear is sleeved on the mounting shaft 4. A rack is slidably mounted inside the base 1, meshing with the gear. Two sets of symmetrically distributed movable frames 9 are slidably mounted on both sides of the mounting frame 2. Each movable frame 9 is rotatably mounted with a locking seat 10. The two ends of the winding roller 12 are respectively positioned corresponding to the two sets of movable frames 9, and the two ends of the winding roller 12 are movably engaged with the two sets of locking seats 10. The rotating frame 3 corresponds to the axis of the upper winding roller 12. A mounting rod 14 is fixedly installed on the rotating frame 3. A first adjusting rod 15 is slidably installed inside the mounting rod 14, and a second adjusting rod 16 is slidably installed inside the first adjusting rod 15. A fixed rod 21 is provided on the rotating frame 3, and the fixed rod 21 is movably engaged with the second adjusting rod 16. Multiple sets of vacuum suction cups 23 are provided inside the fixed rod 21, and the multiple sets of vacuum suction cups 23 are connected in parallel through connecting pipes 22. Two sets of take-up rollers 12 are provided with mounting grooves 13, and the mounting grooves 13 are correspondingly set with the fixed rods 21. The fixed rods 21 can be engaged with the take-up rollers 12 through the mounting grooves 13. A cylinder 7 is fixedly installed inside the base 1, and the rack is fixedly connected to the output end of the piston rod of the cylinder 7. A circulating... The outlet of the circulating air pump 8 and the cylinder 7 are connected to the inlet of the circulating air pump 8 via a purification pipeline. The outlet of the circulating air pump 8 is connected to the inlet of the cylinder 7 via a high-pressure air pipe. Two sets of bidirectional lead screws 11 are rotatably installed inside the mounting frame 2. The bidirectional lead screws 11 are correspondingly set with two sets of movable frames 9. The two ends of the bidirectional lead screws 11 pass through the two sets of movable frames 9 and are threadedly connected to the two sets of movable frames 9 respectively. Through the fixed rod 21 and its integrated multiple sets of parallel vacuum suction cups 23, in conjunction with the externally connected air source, reliable adsorption and fixation of the end of the packaging material waiting to be wound is achieved. During operation, the fixed rod 21 can be accurately inserted into the mounting groove 13 of the new winding roller 12 for locking and positioning. The motor on the moving frame 9 drives the winding roller 12 and the motor on the base 1 drives the rotating frame 3, so that the rotating frame 3 and the winding roller 12, which are on the same axis, can rotate together to efficiently complete the winding of the packaging material. After winding, the locking rod 21 and the second adjusting rod 16 can be quickly released by operating the handle 29 in conjunction with the gear and rack mechanism, and the external air source can be turned off to release the material end of the vacuum suction cup 23. The fixing rod 21 can then be easily pulled out from the second adjusting rod 16 and the mounting groove 13. This process is highly automated, replacing the traditional cumbersome manual traction, positioning and pasting operations, significantly shortening the roll change time and providing key technical support for continuous winding.

[0025] like Figures 2-6As shown, a threaded rod 17 is rotatably installed inside the mounting rod 14. The lower end of the threaded rod 17 passes through the first adjusting rod 15 and is threadedly connected to the first adjusting rod 15. A threaded tube 19 is rotatably installed inside the first adjusting rod 15. The lower end of the threaded tube 19 passes through the second adjusting rod 16 and is threadedly connected to the second adjusting rod 16. Two sets of symmetrically distributed limiting grooves 18 are provided on the threaded rod 17. Two sets of symmetrically distributed limiting blocks 20 are provided inside the threaded tube 19. The limiting blocks 20 are correspondingly arranged with the limiting grooves 18. The threaded tube 19 is slidably sleeved with the threaded rod 17 through the limiting blocks 20 and the limiting grooves 18. Two symmetrically distributed slides 24 are slidably installed inside rod 16. Each slide 24 has a fixed insert rod 25, which is movably engaged with a fixed rod 21. A first spring 26 is sleeved on each slide 24, with its two ends connected to the insert rod 25 and the second adjusting rod 16, respectively. A rack is fixedly installed on each slide 24, and a gear is provided between the two slides. The gear meshes with the two racks, and the gear is rotatably connected to the second adjusting rod 16 via a handle 29. A torsion spring 30 is sleeved on the handle 29, with its two ends connected to the gear and the second adjusting rod, respectively. 16 is fixedly connected. Two sets of slide rods 31, corresponding to the slide frame 24, are fixedly installed inside the second adjusting rod 16. The slide frame 24 and the slide rods 31 are slidably connected. Two sets of symmetrically distributed second springs 32 are sleeved on the slide rods 31. The two ends of the second springs 32 are fixedly connected to the slide frame 24 and the second adjusting rod 16, respectively. Through the multi-stage telescopic structure of the mounting rod 14, the first adjusting rod 15, and the second adjusting rod 16, precise and stable adjustment of the working height of the fixed rod 21 can be achieved. When the vacuum adsorption function is not activated, the fixed rod 21 can be adjusted to an appropriate height so that it lightly presses against the rotating surface. The surface of the take-up roller 12 effectively smooths the packaging material being wound, preventing wrinkles or loosening, and significantly improving the flatness and compactness of the entire roll. When a roll of material is finished winding, the air source can be immediately activated to allow the vacuum suction cup 23 to adhere to the material end. Workers can then perform neat cutting in this state. Subsequently, using the height adjustment function, the fixing rod 21, holding the new end, can be easily and precisely positioned and inserted into the mounting groove 13 of the next set of empty take-up rollers 12, ensuring that the material end is flat, secure, and precisely fixed, laying the foundation for high-quality winding of the next roll. This function greatly simplifies roll-changing operations, ensures the flatness of the starting section of winding, and effectively reduces quality problems caused by poor end fixing.

[0026] This utility model provides a winding device suitable for packaging material production. The specific working principle is as follows: Two sets of winding rollers 12 are typically installed on the mounting frame 2, one set is in operation and the other is idle and ready for use. The operating winding roller 12 is driven to rotate by a motor on the corresponding moving frame 9 to perform normal winding of the packaging material. By adjusting the height of the mounting rod 14, the first adjusting rod 15, and the second adjusting rod 16, the fixing rod 21 can be lightly pressed against the surface of the operating winding roller 12. At this time, the vacuum suction cup 23 is not working, and the fixing rod 21 acts as a pressure roller to help smooth the material and ensure a flat and tight winding. When the winding material on the operating winding roller 12 reaches the preset full-winding state, the system prepares to switch, turning on the air source connected to the external vacuum suction cup 23. Together with the connecting pipe 22, this causes the multiple sets of parallel vacuum suction cups 23 to generate suction force, firmly securing the material. The packaging material is grasped, and the staff can cut it neatly in this state. Then, using the height adjustment function, the fixing rod 21 can be accurately inserted into the mounting groove 13 of the new take-up roller 12 for locking and positioning. The motor on the moving frame 9 drives the take-up roller 12 and the motor on the base 1 drives the rotating frame 3, so that the rotating frame 3 and the take-up roller 12, which are on the same axis, can rotate together to efficiently complete the winding of the packaging material. After winding, the locking between the fixing rod 21 and the second adjusting rod 16 can be quickly released by operating the handle 29 in conjunction with the gear and rack mechanism, and the external air source can be turned off to release the material end of the vacuum suction cup 23. The fixing rod 21 can then be easily pulled out from the second adjusting rod 16 and the mounting groove 13. This process is highly automated and replaces the traditional cumbersome manual traction, positioning and pasting operations, significantly shortening the roll change time.
