Description

Technical Field

[0001] This utility model relates to the field of plastic sealant production technology, specifically a cooling device for producing anti-breakage and wear-resistant plastic sealant. Background Technology

[0002] Plastic sealing films are widely used in scenarios requiring "wear resistance, waterproofing, and bending resistance," such as ID cards, menus, and outdoor signage. In recent years, high-end film materials, represented by "anti-friction and wear-resistant plastic sealing films," have achieved the following performance indicators by coating a nano-SiO2 hardened layer on the surface of a PET substrate, adding an elastic PU interlayer in the middle, and then laminating it with EVA hot melt adhesive at the bottom: folding resistance: MIT ≥ 50,000 folds (GB / T 457), surface pencil hardness: ≥ 3H (ASTM D3363), dynamic friction coefficient: ≤ 0.18 (GB10006), haze increase: < 1% after hot pressing (GB / T 2410). However, the aforementioned multi-layered heterogeneous structure brings the dual characteristics of "high heat capacity + high elastic recovery," making traditional cooling methods unable to meet its quality requirements.

[0003] A cooling device for producing and processing plastic sealant, with announcement number CN222681502U, cools the plastic sealant by spraying water through a nozzle and then aligns and dries it by a rotating roller with cotton cloth. However, this can easily cause microparticles in the water and fibers from the cotton cloth to adhere to the surface of the plastic sealant, affecting the production quality of the plastic sealant.

[0004] Therefore, it is essential to design a cooling device for the production of anti-breakage and wear-resistant plastic sealant that can provide high-quality cooling for the sealant. Utility Model Content

[0022] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-5 The present invention provides a technical solution: a cooling device for the production of anti-breakage and wear-resistant plastic sealing film, including a base 1, a cooling component 2 is provided on the upper side of the base 1, and an infeed conveyor roller 3 and an outfeed conveyor roller 4 are respectively provided on both sides of the cooling component 2 along the conveying direction. The infeed conveyor roller 3 and the outfeed conveyor roller 4 are rotatably connected to a bracket, and the bracket is fixedly connected to the base 1.

[0024] The cooling assembly 2 includes a housing 5, which is fixedly connected to the upper side of the base 1. A cooling chamber 6 is provided inside the housing 5. A feed inlet 7 is provided on the side of the cooling chamber 6 near the infeed conveyor roller 3, and a discharge outlet 8 is provided on the side of the cooling chamber 6 near the outfeed conveyor roller 4.

[0025] Two rotatable electrostatic adsorption rollers 9 are installed inside the feed inlet 7. The two electrostatic adsorption rollers 9 are arranged one above the other. The two electrostatic adsorption rollers 9 can adsorb the micro dust on the surface of the plastic seal film onto the electrostatic adsorption rollers 9, thereby completing the dust removal work of the plastic seal film.

[0026] Each of the two electrostatic adsorption rollers 9 has a connecting frame 10 on one side facing away from each other. The connecting frame is U-shaped. The feed port 7 has a groove 11 corresponding to the connecting frame 10. The connecting frame 10 is located in the groove 11 and is slidably connected to the groove 11.

[0027] The electrostatic adsorption roller 9 is rotatably connected to the connecting frame 10. Two electric telescopic rods 12 are vertically arranged on opposite sides of the two connecting frames 10. The two electric telescopic rods 12 are respectively located at both ends of the connecting frame 10 along the length direction. The fixed end of the electric telescopic rod 12 is fixedly connected to the inner wall of the groove 11, and the output end of the electric telescopic rod 12 is fixedly connected to the connecting frame 10. In this way, the two electrostatic adsorption rollers 9 are driven to move relative to each other in the vertical direction through the electric telescopic rods 12, thereby adsorbing and transferring plastic sealant films of different thicknesses.

[0028] Two connecting brackets 10 are fixedly connected to a suction nozzle 13 on the side facing the electrostatic adsorption roller 9. The input port of the suction nozzle 13 is rectangular, and the length direction of the input port of the suction nozzle 13 is consistent with the length direction of the electrostatic adsorption roller 9.

[0029] Two suction nozzles 13 are connected to an air pump at one end along their length via a three-way valve and a pipe. The air pump creates a negative pressure at the inlet of the suction nozzle 13, which then removes the dust particles from the electrostatic adsorption roller 9.

[0030] Two rotatable pressure rollers 14 are installed inside the discharge port 8. The two pressure rollers 14 are arranged one above the other. A connecting frame 2 15 is provided on one side of each of the two pressure rollers 14. The connecting frame 2 15 is U-shaped. A groove 2 16 is opened in the discharge port 8 corresponding to the connecting frame 2 15. The connecting frame 2 15 is located in the groove 2 16 and is slidably connected to the groove 2 16.

[0031] The pressure roller 14 is rotatably connected to the connecting frame 2 15. Both ends of the connecting frame 2 15 along the length direction are fixedly connected to the slider 17. The groove 2 16 is fixedly connected to the two sliders 17. The fixing block 18 is provided with a guide groove 19. The slider 17 is located in the guide groove 19 and is slidably connected to the guide groove 19. A vertically arranged guide rod 20 is fixedly connected in the guide groove 19. The guide rod 20 passes through the slider 17 and is slidably connected to the slider 17. A spring 21 is sleeved on the guide rod 20. The spring 21 is located on the upper side of the slider 17. One end of the spring 21 abuts against the slider 17, and the other end of the spring 21 abuts against the upper inner wall of the guide groove 19.

[0032] In this way, the elastic action of the spring 21 ensures that the roller surfaces of the two pressure rollers 14 are always in direct contact with the surface of the plastic sealant and rotate.

[0033] Cooling plates 22 are provided on both the upper and lower sides of the cooling chamber 6. The cooling plates 22 are used to control the temperature inside the cooling chamber 6 within the temperature threshold required for cooling the plastic sealant.

[0034] The cooling chamber 6 is equipped with several rotatable rollers 23, which are arranged in an alternating pattern along the length of the cooling chamber 6.

[0035] The top of the upper row of rotating rollers 23 is at the same horizontal level as the center of the feed inlet 7, and the upper row of rotating rollers 23 is rotatably connected to the inner wall of the cooling chamber 6.

[0036] Both ends of the lower row of rotating rollers 23 along the axial direction are rotatably connected to sliders 24. The inner wall of the cooling chamber 6 is provided with a groove 25 corresponding to sliders 24. An electric telescopic rod 26 is provided on the upper side of sliders 24. The fixed end of the electric telescopic rod 26 is fixedly connected to the upper inner wall of the groove 25. The output end of the electric telescopic rod 26 is fixedly connected to sliders 24. In this way, the distance between the lower row of rotating rollers 23 and the upper row of rotating rollers 23 is controlled by the electric telescopic rod 26, thereby adjusting the cooling time of the plastic seal film in the cooling chamber 6 according to the thickness of the plastic seal film.

[0037] Each roller 23 has a cooling channel 27 along its axial direction. The cooling channel 27 is a spiral pipe and is filled with a recirculating coolant.

[0038] The cooling chamber 27 is connected to an outlet rotary joint and an inlet rotary joint at both ends along the axis of the roller 23. Both the outlet rotary joint and the inlet rotary joint are connected to a liquid storage tank through pipes. The pipe connecting the inlet rotary joint to the liquid storage tank is connected to a pump body, which drives the coolant to circulate.

[0039] A rotatable roller 28 is provided on the lower side of the output conveyor roller 4 away from the cooling component 2. The two ends of the roller 28 are rotatably connected to the bracket to which the output conveyor roller 4 is connected in the axial direction.

[0040] A drive motor 29 is fixedly connected to the bracket corresponding to the roller 28. One end of the central axis of the roller 28 passes through the bracket and is fixedly connected to the output shaft of the drive motor 29. The vertex of the conveyor roller 4 and the center of the discharge port 8 are on the same horizontal line.

[0041] An electrostatic eliminator 30 is provided on the side of the conveyor roller 4 near the pressure roller 14 to eliminate residual voltage on the surface of the plastic sealant film and prevent electrostatic shock from occurring after subsequent winding, which could damage the plastic sealant film.

[0042] In this embodiment, the plastic sealing film is passed sequentially through the conveyor roller, electrostatic adsorption roller 9, rotating roller 23, pressure roller 14, and output conveyor roller 4 from the manually pulled end and finally fixed on the roll roller 28.

[0043] The drive motor 29 is started to drive the roller 28 to rotate, thereby traction of the plastic sealant film. The plastic sealant film passes through the electrostatic adsorption roller 9 from the inlet conveyor roller 3 and enters the cooling chamber 6 through the feed port 7.

[0044] When passing through the electrostatic adsorption roller 9, the electrostatic adsorption roller 9 can electrostatically adsorb the micro dust attached to the surface of the plastic seal film. When the adsorbed micro dust rotates to the position of the suction nozzle 13 input port, it is adsorbed into the suction nozzle 13 under the action of the air pump, thereby completing the dust removal work of the electrostatic adsorption roller 9.

[0045] After the plastic sealant enters the cooling chamber 6 through the feed port 7, the temperature inside the cooling chamber 6 is cooled by the cooling plate 22. Therefore, when the plastic sealant enters the cooling chamber 6, it can be cooled by the air inside the cooling chamber 6.

[0046] Meanwhile, the rotating roller 23 inside the cooling chamber 6 is in direct contact with the plastic sealant, and during the rotation process, the cooling chamber channel 27 directly absorbs the heat of the plastic sealant through the outer wall of the rotating roller 23, thereby improving the cooling efficiency of the plastic sealant.

[0047] During this process, the distance between the upper and lower rows of rotating rollers 23 can be adjusted according to the thickness of the plastic sealant, thereby adjusting the length of the moving path of the plastic sealant in the cooling chamber 6 and thus controlling the cooling time of the plastic sealant in the cooling chamber 6.

[0048] After the plastic sealant is cooled in the cooling chamber 6, it is removed from the box 5 through the discharge port 8 and passes through the pressure rollers 14. The two pressure rollers 14 flatten the cooled plastic sealant a second time to prevent wrinkles from forming.

[0049] Finally, the plastic sealant, after being flattened twice, is wound up by the conveyor roller 4 and then by the winding roller 28.
