Description

Technical Field

[0001] This utility model relates to the field of winding device technology, and in particular to a device for winding foam backing tape. Background Technology

[0002] In logistics, electronic product packaging, and fresh food cold chain industries, foam boxes are a core packaging material for protecting fragile, delicate, or easily damaged goods due to their lightweight and excellent cushioning properties. To further enhance the structural strength of foam boxes, prevent cracking during transportation, and improve packaging sealing to isolate moisture and dust, foam backing tape is wrapped around the outside of the foam box, forming a composite protective structure of "box body and tape." This packaging step directly relates to the safety and consistency of goods transportation and is a crucial process for ensuring the integrity of products from production to consumption. In existing technologies, most wrapping is done manually, relying entirely on the experience and skill of the operators, resulting in extremely low work efficiency. Operators need to hold the tape roll and repeatedly wrap it around the foam box, which is not only labor-intensive and prone to fatigue, but also often takes several times longer than automated equipment to wrap a single box. Especially during peak order periods, insufficient manpower can directly lead to production chain blockages. Utility Model Content

[0015] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described below.

[0016] To address the problems existing in the background art, this application proposes the following technical solution: a device for winding foam backing tape, comprising a roller conveyor 1, an opening on one side of the roller conveyor 1, and a lifting and rotating mechanism below the opening; a fixed frame 13 is fixedly connected to the outer side of the roller conveyor 1, a synchronous frame 19 is provided on the top of the fixed frame 13, a height adjustment mechanism is provided between the synchronous frame 19 and the fixed frame 13, and a side frame 26 is fixedly connected to the outside of the synchronous frame 19; both the top of the synchronous frame 19 and the top of the side frame 26 are... The frame 26 is rotatably connected to a hinge shaft 31. The outside of the two hinge shafts 31 is rotatably connected to a first hinge frame 20 and a second hinge frame 32, respectively. The outside of the first hinge frame 20 is rotatably connected to multiple sets of first guide rollers 21. The outside of the second hinge frame 32 is rotatably connected to a third guide roller 30. The top of the side frame 26 is rotatably connected to a second guide roller 28 and a film roller 27. The outside of the synchronization frame 19 is also provided with an adjustment mechanism for adjusting the angle of the first hinge frame 20 and the second hinge frame 32. The top of the synchronization frame 19 is also provided with a cutting mechanism. In the above technical solution, the roller conveyor 1 provides an automated conveying channel for foam boxes, replacing manual handling and feeding, significantly improving work efficiency, especially suitable for batch foam box processing scenarios. The opening design provides space for the lifting and rotating mechanism's jacking action, ensuring that the foam boxes can accurately detach from the conveying surface and complete rotational winding, avoiding interference with conveyor components. The fixed frame 13 provides stable support for the synchronous frame 19, and the height adjustment mechanism can flexibly adjust the position of the synchronous frame 19 according to the height of the foam boxes, so that the guide rollers and film rollers 27 are always adapted to the foam box winding height, improving the device's versatility for foam boxes of different specifications. The first and second hinged frames are rotatably connected by the hinge shaft 31, and the guide roller angle can be flexibly adjusted in conjunction with the adjustment mechanism to ensure that the film always fits tightly against the foam box surface during the winding process, avoiding wrinkles and loosening. Multiple sets of guide rollers cooperate with the film rollers 27 to achieve stable film conveying and guidance, reduce film stretching deformation, and ensure winding quality. The cutting mechanism can automatically cut the film after winding, without manual operation, further improving the level of automation and solving the problems of low efficiency and uneven quality of traditional manual winding. In this embodiment, the lifting and rotating mechanism includes a motor 10 and a second cylinder 8. A mounting frame 7 is fixedly connected to the bottom of the roller conveyor 1. The second cylinder 8 is fixedly connected to the mounting frame 7. A top plate 9 is fixedly connected to the output end of the second cylinder 8. The motor 10 is fixedly connected to the bottom of the top plate 9. A rotating rod 11 is fixedly connected to the output end of the motor 10. A rotating plate 12 is fixedly connected to the top of the rotating rod 11. Limiting plates 33 are fixedly connected to both sides of the top of the rotating plate 12.

[0017] The mounting frame 7 provides a stable base for the second cylinder 8 and the motor 10, ensuring stable operation of the lifting and rotating mechanism under heavy loads. The second cylinder 8, acting as the lifting power source, drives the rotating plate 12 and the foam box to rise smoothly via the top plate 9, detaching them from the surface of the roller conveyor 1. This prevents friction between the foam box and the conveyor rollers during winding, thus avoiding impact on rotational accuracy. The motor 10 drives the rotating plate 12 to rotate via the rotating rod 11, causing the foam box to rotate synchronously, achieving circumferential winding of the film. Compared to manual rotation, the motor 10 has a stable speed, ensuring uniform film winding spacing and improving winding consistency. The limiting plate 33 at the top of the rotating plate 12 positions the foam box from both sides, preventing it from shifting or slipping during rotation. This is especially suitable for foam boxes with smooth surfaces, ensuring stability during the winding process. The lifting and rotating actions are independently controllable, allowing precise adjustment of the lifting height and rotation speed according to winding requirements. This adapts to foam boxes of different heights and sizes, further enhancing the device's versatility and solving the problems of inaccurate positioning and poor adaptability in traditional devices. In this embodiment, a bracket 2 is fixedly connected to the top of the roller conveyor 1, a first cylinder 3 is fixedly connected to the bracket 2, a connecting seat 4 is fixedly connected to the output end of the first cylinder 3, a roller 6 is rotatably connected to the bottom of the connecting seat 4, and a guide rod 5 is fixedly connected to the top of the connecting seat 4, the guide rod 5 passing through the bracket 2. The bracket 2 is fixed to the top of the roller conveyor 1, providing stable support for the first cylinder 3 and ensuring structural stability during pressure application. The first cylinder 3 drives the roller 6 downward through the connecting seat 4, which abuts against the top of the foam box. This, in conjunction with the limiting plate 33 of the lifting and rotating mechanism, forms an "upper and lower clamping" positioning, further limiting the movement of the foam box during rotation and improving winding stability. The roller 6 is rotatably connected to the bottom of the connecting seat 4. When the foam box rotates, the roller 6 rotates synchronously, preventing sliding friction with the foam box surface that could cause damage and protecting the product's appearance. The guide rod 5 passes through the bracket 2, providing precise guidance for the lifting movement of the connecting seat 4. This prevents the connecting seat 4 from shifting when the first cylinder 3 pushes, ensuring that the roller 6 always precisely abuts against the center of the foam box, avoiding deformation due to uneven force. This flexible clamping structure ensures effective positioning and adapts to foam boxes of different heights, avoiding damage caused by rigid clamping and improving operational safety and reliability. In this embodiment, the height adjustment mechanism is a threaded rod 15 rotatably connected to the fixed frame 13. The threaded rod 15 is externally threaded with a nut seat 14. A guide post 16 is fixedly connected to the top of the fixed frame 13. The guide post 16 passes through the nut seat 14 and is fixedly connected to a connecting plate 17. The synchronous frame 19 is fixedly connected to the nut seat 14. A handwheel 18 is fixedly connected to the top of the threaded rod 15. The threaded engagement between the threaded rod 15 and the nut seat 14 converts the rotational motion of the handwheel 18 into the linear lifting motion of the nut seat 14, thereby driving the synchronous frame 19 to adjust its height. The adjustment method is simple and convenient, requiring no specialized tools from the operator. The handwheel 18 is designed with increased operating torque, reducing the labor intensity of height adjustment and facilitating precise control of the lifting amplitude of the synchronous frame 19, ensuring accurate matching between the guide roller and the foam box height. The guide post 16 penetrates the nut seat 14, providing stable guidance for its lifting motion and preventing it from shifting with the rotation of the threaded rod 15. This ensures smooth lifting of the synchronous frame 19 and avoids inaccurate guide roller positioning due to shifting, which could affect the winding quality. The connecting plate 17 is fixed to the top of the guide post 16, limiting the lifting stroke of the nut seat 14 to prevent damage from over-adjustment and enhancing the structural stability of the guide post 16. In this embodiment, the adjustment mechanism includes a first electric push rod 22 and a second electric push rod 29. The first electric push rod 22 is hinged to the synchronous frame 19, and the second electric push rod 29 is hinged to the side frame 26. The output end of the first electric push rod 22 is hinged to the first hinge frame 20, and the output end of the second electric push rod 29 is hinged to the second hinge frame 32. The first electric push rod 22 and the second electric push rod 29 provide angle adjustment power for the first hinge frame 20 and the second hinge frame 32, respectively. The first electric push rod 22 and the second electric push rod 29 have stable output force and precise stroke control, allowing for precise adjustment of the hinge frame's tilt angle through extension and retraction, thereby changing the position of the guide rollers. This ensures the film adheres tightly to different parts of the foam box (such as the top and sides), improving winding quality. The first electric push rod 22 and the second electric push rod 29 are all hinged to the first hinge frame 20, the second hinge frame 32, and the synchronous frame 19 / side frame 26, allowing the push rods to adapt to the rotation angle of the hinge frame during extension and retraction, avoiding rigid stress that could damage components and extending the device's service life. By independently controlling the movement of the first hinge frame 20 and the second hinge frame 32, individual or synchronous adjustment of the first hinge frame 20 and the second hinge frame 32 can be achieved, adapting to the complex shape of the foam box and solving the problem of inflexible adjustment in traditional fixed guide structures. The automated control method of the electric push rod can be linked with the overall control system of the device to realize the dynamic adjustment of the guide angle during the winding process, further improving the automation level and accuracy of winding. In this embodiment, the cutting mechanism includes a third cylinder 24 and a cutting blade 25 fixedly connected to the output end of the third cylinder 24. A fixed frame 23 is fixedly connected to the top of the synchronization frame 19, and the third cylinder 24 is fixedly connected in the fixed frame 23. The fixed frame 23 provides a stable mounting support for the third cylinder 24, ensuring the stability of the cylinder and the cutting blade 25 during the cutting process and preventing cutting deviation due to vibration. The third cylinder 24 serves as the cutting power source, driving the cutting blade 25 to move quickly and smoothly, achieving instantaneous cutting of the film with high cutting efficiency and a clean cut. The usage method of this embodiment is as follows: Place the device on a flat working area and check whether the roller conveyor 1 runs smoothly and whether the connections of components such as the lifting and rotating mechanism, guide rollers, and cutting mechanism are secure. Based on the height of the foam box, rotate the handwheel 18 to adjust the height of the synchronization frame 19 via the threaded rod 15, aligning the guide roller with the center of the foam box. Initially adjust the angles of the first hinge frame 20 and the second hinge frame 32 using the first electric push rod 22 and the second electric push rod 29 to ensure the guide roller fits against the side of the foam box. Install the film on the film roller 27, and pull one end of the film through the second guide roller 28, the third guide roller 30, and multiple sets of first guide rollers 21, leaving sufficient length for bonding with the foam box. Start the roller conveyor 1, place the foam box on the conveyor belt, and stop the conveyor when it corresponds to the position of the rotating plate 12. Start the second cylinder 8, push the top plate 9 to drive the rotating plate 12 to rise, lift the foam box away from the conveyor roller, and the limiting plate 33 on the rotating plate 12 positions the foam box from both sides; start the first cylinder 3, push the connecting seat 4 to drive the roller 6 to descend, and abut against the top of the foam box to form a "clamping" fixation. Attach one end of the pre-reserved film to the surface of the foam box. Activate the first and second electric push rods and precisely adjust the angles of the first and second hinge frames to ensure that each guide roller is tightly fitted to the surface of the foam box. Start the motor 10, which drives the rotating plate 12 and the foam box to rotate at a uniform speed via the rotating rod 11. Under the guidance of the guide rollers, the film is evenly wrapped around the outside of the foam box. During the wrapping process, the speed of the motor 10 and the angle of the electric push rods can be adjusted as needed to ensure that the film layers are tight and wrinkle-free. After reaching the preset number of winding turns, stop the rotation of motor 10 and the foam box. Start the third cylinder 24 to push the cutting blade 25 to quickly cut the film. After cutting, close the third cylinder 24 to reset the cutting blade 25. Close the first and second cylinders in sequence, the roller 6 rises and the rotating plate 12 falls, and the foam box falls back onto the roller conveyor 1. Start the conveyor to transport the wound foam box to the next process. Turn off the main power supply of the device, clean the film residue and debris on the roller conveyor 1, guide roller, and cutter 25; check whether each cylinder, electric push rod, and motor 10 are operating normally, and whether there are any abnormal noises or leaks; add lubricating oil to moving parts such as threaded rod 15 and guide column 16 to ensure smooth use next time; cover the device with a dust cover and place it in a dry and ventilated area.
