Technical Field
[0001] This utility model relates to the field of winding device technology, and in particular to an automatic winding device for a hot melt adhesive laminating machine. Background Technology
[0002] Hot melt adhesive is a type of plastic adhesive whose physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic and odorless, and is an environmentally friendly chemical product. Hot melt adhesive film is a film product with or without release paper, which can be easily operated continuously or intermittently. It can be widely used for bonding various fabrics, papers, polymer materials and metals.
[0003] In the existing technology, hot melt adhesives require a winding device to wind them up during the production process. However, most of the existing winding devices have rollers that are directly fitted onto the outside of the rotating shaft, and the roller baffles are tightened with bolts. This fixing method makes it inconvenient to remove the hot melt adhesive from the winding device after it has been wound up. The removal process wastes time and effort, reduces the winding efficiency of the hot melt adhesive, and reduces the practicality of the winding device. Utility Model Content

A locking block 14 is fixedly installed on the lower surface of the pressing frame 13. A slot 15 is opened on the upper surface of both ends of the worktable 1. The locking block 14 and the slot 15 are both T-shaped. The locking block 14 is slidably connected to the inner wall of the slot 15. A fixing bolt 16 is threadedly connected to the upper surface of the pressing frame 13. The fixing bolt 16 penetrates the upper surface of the pressing frame 13 and is inserted into the upper surface of the worktable 1.
[0033] To facilitate the placement of the rolled release film into the mounting frame 2, a positioning rod 17 is inserted into one side wall of the mounting frame 2. The positioning rod 17 penetrates the mounting frame 2. A limiting plate 18 is fixedly installed at one end of the positioning rod 17. A film rolling roller 19 is sleeved on the outer surface of the positioning rod 17 inside the mounting frame 2. A fixing sleeve 20 is sleeved on the other end of the positioning rod 17.

[0034] By setting up a workbench 1, mounting frame 2, support roller 3, pressure roller 4, fixing plate 5, motor 6, rotating rod 7, turntable 8, take-up roller 9, limiting rod 10, fixing rod 11, placement roller 12, pressing frame 13, clamping block 14, clamping groove 15, fixing bolt 16, positioning rod 17, limiting plate 18, film rolling roller 19, fixing sleeve 20, pressure plate 21, limiting block 22, and limiting bolt 23, the device achieves quick and convenient installation and disassembly of the take-up roller 9 and placement roller 12. This improves the installation method of the roller in the existing technology, allowing the hot melt adhesive to be quickly removed from the take-up device after winding, saving time and effort, accelerating the winding efficiency of hot melt adhesive, and improving the practicality of the take-up device.
[0035] The mounting frame 2 is internally equipped with a lifting assembly, which includes two slides 24 and two slides 25. The two slides 24 are respectively opened on the two side walls of the mounting frame 2, and the two slides 25 are respectively set on the inner walls of the two slides 24. The inner walls of the slides 24 are fixedly installed with slide rods 26. The opposite side walls of the two slides 25 are fixedly connected with connecting rods 27. The pressure roller 4 is sleeved on the outer surface of the connecting rod 27. The outer surface of the slide 25 is inserted with a plug rod 28. The upper surface of the slide 25 is inserted with the slide rod 26. The plug rod 28 passes through the side wall of the slide 25. Both side walls of the mounting frame 2 are provided with multiple insertion holes for insertion with the plug rod 28. The end of the plug rod 28 away from the slide 25 is fixedly installed with a pull plate 29. The outer surface of the plug rod 28 is sleeved with a tension spring 30. One end of the tension spring 30 is fixedly connected to the slide 25, and the other end of the tension spring 30 is fixedly connected to the pull plate 29.
[0036] By setting up the slide groove 24, slide frame 25, slide rod 26, connecting rod 27, insert rod 28, pull plate 29 and tension spring 30, the function of conveniently and quickly raising and lowering the position of the pressure roller 4 is realized. By setting the pressure roller 4 on the outer surface of the slide frame 25, when the slide frame 25 slides inside the slide groove 24, it can drive the pressure roller 4 to rise or fall, thereby making it more convenient to pass the hot melt adhesive and release film between the support roller 3 and the pressure roller 4. On the original basis, the practicality of the winding device is further improved.
[0037] Working principle: When using the winding device to wind up hot melt adhesive, the placement roller 12 with hot melt adhesive is placed on the outer surface of the fixed rod 11, and the blank winding roller 9 is placed on the outer surface of the rotating rod 7. One end of the hot melt adhesive is pulled so that the hot melt adhesive passes through the mounting frame 2 and connects to the outer surface of the winding roller 9. At the same time, the release film placed on the film winding roller 19 is pulled so that the release film adheres to the outer surface of the hot melt adhesive. Then the motor 6 is started. When the motor 6 runs, it drives the rotating rod 7 to rotate. When the rotating rod 7 rotates, it drives the winding roller 9 to rotate through the turntable 8 and the limiting rod 10, thereby winding up the hot melt adhesive and the release film onto the outer surface of the winding roller 9.
[0038] When the hot melt adhesive and release film are passed through the mounting frame 2, the two pull plates 29 are pulled, causing the insert rod 28 to extend away from the slide 25. The tension spring 30 is stretched and deformed. Then, the slide 25 is pulled upward, causing it to slide upward along the slide rod 26 inside the slide groove 24. At the same time, the pressure roller 4 is driven to rise through the connecting rod 27. Then, the hot melt adhesive with the release film is passed between the support roller 3 and the pressure roller 4. After the hot melt adhesive and release film have passed through, the above operation is reversed, causing the pressure roller 4 to descend. When the pressure roller 4 contacts the hot melt adhesive and release film, it presses the hot melt adhesive and release film together with the support roller 3. During the winding process, the release film is adhered to the outer surface of the hot melt adhesive.
[0039] After the hot melt adhesive is wound up, tighten the fixing bolt 16 to extend it upwards. After the fixing bolt 16 separates from the worktable 1, release the fixing of the pressing frame 13. Then pull the pressing frame 13 away from the take-up roller 9 and the placement roller 12. The pressing frame 13 slides on the upper surface of the worktable 1, and the locking block 14 slides inside the locking groove 15. After the pressing frame 13 is removed from the upper surface of the worktable 1, release the pressing and positioning of the take-up roller 9 and the placement roller 12. Then remove the take-up roller 9 and the placement roller 12. The take-up roller 9 slides on the outer surface of the rotating rod 7 and separates from the limiting rod 10. The placement roller 12 slides on the outer surface of the fixing rod 11. After the take-up roller 9 separates from the rotating rod 7 and the placement roller 12 separates from the fixing rod 11, the wound hot melt adhesive is removed from the winding device, and the next operation can be carried out.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
