Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive packaging film production technology, specifically a cooling structure for hot melt adhesive packaging film production. Background Technology

[0002] Hot melt adhesive packaging film is a type of film product with or without release paper. It can be easily processed continuously or intermittently and can be widely used for bonding various fabrics, papers, polymer materials and metals. According to its usage characteristics, hot melt adhesive film is divided into two main categories: thermoplastic and thermosetting. When producing hot melt adhesive packaging film, a cooling structure for hot melt adhesive packaging film production is required.

[0003] In existing cooling devices, the upper surface of the packaging film is typically cooled first by air blowing. This results in uneven air blowing between the upper and lower surfaces, leading to inconsistent cooling effects and efficiency. Consequently, the overall cooling effect of the packaging film is reduced. Furthermore, the guide roller spacing in existing cooling devices is fixed, preventing operators from adjusting the spacing based on the actual thickness of the packaging film. This causes stress concentration at the edges of the packaging film, affecting the processing quality and reducing the overall practicality of the device.

[0004] Compared with the patent application number CN221697890U, this utility model relates to the field of hot melt adhesive film production technology and discloses a cooling device for anti-wrinkle hot melt adhesive film production. The device includes a main body, which uniformly cools the hot melt adhesive film through air outlet slots evenly distributed on the top of the cooling chamber. By setting a second guide roller, the hot melt adhesive film cooled by the cooling chamber enters the second guide roller when passing through the discharge port, and the hot melt adhesive film is flattened again, which effectively enhances the practicality of the device.

[0005] The above solution can effectively cool the packaging film by blowing air. However, when blowing air, the solution still prioritizes the upper surface of the packaging film, resulting in uneven cooling effect and efficiency between the upper and lower surfaces. Furthermore, the spacing of the guide rollers in the above solution is fixed, which makes it impossible to adjust the spacing of the guide rollers according to the thickness of the packaging film, thus reducing the overall flexibility of the device.

[0006] Based on this, a cooling structure for the production of hot melt adhesive packaging film is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, such as Figures 1-6 As shown, a cooling structure for hot melt adhesive packaging film production includes a cooling box 1. The upper and lower surfaces of the cooling box 1 are symmetrically provided with mounting holes. Side plates 2 are symmetrically installed on both sides of the cooling box 1. Guide rollers 3 are symmetrically provided between every two side plates 2. Connecting plates 4 are rotatably connected to both ends of the guide rollers 3. A blower assembly, located within the mounting hole, is used to cool the packaging film; Cooling components are respectively installed on the upper and lower surfaces of the cooling box 1, and are used to improve the cooling effect of the blowing components on the packaging film; A dustproof component is installed outside the cooling and heat dissipation component and is used to protect the packaging film from dust. An adjustment assembly is disposed on the surfaces of two of the side plates 2 and is used to adjust the spacing of the guide rollers 3.

[0023] In this embodiment, when cooling of the packaging film is required, one end of the packaging film is simply passed through the space between multiple guide rollers 3 and inside the cooling box 1 and wound onto the external winding device. At this time, the blowing assembly starts operating, effectively blowing air from the external environment into the cooling box 1. This air is then blown onto the upper and lower surfaces of the packaging film, effectively cooling both surfaces. Simultaneously, the cooling assembly also starts operating, effectively cooling the air from the external environment. The blowing assembly can effectively blow cold air to the upper and lower surfaces of the packaging film, further improving the cooling efficiency and effect of the packaging film. The dustproof assembly can effectively prevent the blowing assembly from sucking dust and other impurities from the external environment into the cooling box 1, further improving the production and processing quality of the packaging film. When it is necessary to adjust the spacing of the guide rollers 3 according to the actual thickness of the packaging film, the spacing of the guide rollers 3 can be adjusted conveniently and effectively by adjusting the assembly, so that the guide rollers 3 can effectively guide and flatten packaging films of different thicknesses, further improving the overall practicality and adjustment flexibility of the device. In one embodiment, such as Figure 2 As shown, the blowing assembly includes an inlet fan 7 fixedly installed on the inner wall of multiple mounting holes. When the packaging film needs to be cooled, the inlet fan 7 starts to run. At this time, the inlet fan 7 can effectively draw the gas in the external environment into the cooling box 1 and blow it onto the upper and lower surfaces of the packaging film, thereby effectively cooling the upper and lower surfaces of the packaging film and effectively improving the cooling efficiency and effect of the packaging film.

[0024] In one embodiment, such as Figure 2As shown, the cooling assembly includes mounting frames 8 fixedly installed on the upper and lower surfaces of the cooling tank 1, respectively. A serpentine cooling tube 9 is fixedly installed on the inner wall of the mounting frame 8. A support frame 5 is fixedly connected to the surface of the cooling tank 1. A liquid pump 10 and a refrigeration cylinder 11 are fixedly installed on the upper surface of the support frame 5. Multiple refrigeration plates 12 are fixedly installed on the inner wall of the refrigeration cylinder 11. The liquid inlet of the liquid pump 10 is connected to the bottom of the refrigeration cylinder 11 via a pipe. The liquid outlet of the liquid pump 10 is connected to the liquid inlet of two serpentine cooling tubes 9 via a first branch pipe 15. The liquid outlet of the two serpentine cooling tubes 9 is connected to the upper surface of the refrigeration cylinder 11 via a second branch pipe 16. A drain pipe 14 is connected to the bottom of the refrigeration cylinder 11 via a solenoid valve 13. During the operation of the fan 7, liquid is drawn... Pump 10 will also start running simultaneously (before pump 10 starts running, staff need to add coolant or cold water to cooling cylinder 11). At this time, pump 10 will transfer the coolant in cooling cylinder 11 to two serpentine cooling pipes 9 through the first branch pipe 15. When the gas in the external environment passes through the serpentine cooling pipes 9, the coolant in the serpentine cooling pipes 9 can effectively absorb the heat in the gas, thereby effectively cooling the gas and improving the cooling efficiency and effect of the fan 7 on the packaging film. After the coolant absorbs heat, it will be circulated back to cooling cylinder 11 through the second branch pipe 16. At this time, cooling plate 12 can effectively cool the coolant again. This cycle repeats, effectively improving the cooling effect of the packaging film.

[0025] In one embodiment, such as Figures 1-4 As shown, the dustproof component includes a dustproof mesh cover 6 fitted on the outer wall of the mounting frame 8. Insert plates 17 are symmetrically installed on the surface of the dustproof mesh cover 6, and positioning frames 22 are symmetrically installed on the surface of the mounting frame 8. The surface of the positioning frame 22 is provided with a movable groove for the insert plates 17 to move. By setting the dustproof mesh cover 6, the probability of the intake fan 7 drawing dust and other impurities from the external environment into the cooling box 1 can be effectively reduced.

[0026] In one embodiment, such as Figure 2 and Figure 5As shown, a fixing plate 23 is fixedly connected to the surface of the positioning frame 22. Slide rods 24 are symmetrically installed on the inner wall of the fixing plate 23. A contact plate 25 is slidably connected to the outer wall of every two slide rods 24. A return spring 26 is sleeved on the outside of the slide rod 24. The return spring 26 abuts against the contact plate 25 and the fixing plate 23. A pull ring is fixedly connected to one side of the contact plate 25 through the outer plate 27. Insert rods 28 are symmetrically installed on the other side of the contact plate 25. Slots for the insertion rods 28 are opened on the contact surface of the fixing plate 23 and the positioning frame 22, as well as on the surface of the insert plate 17. When the dust cover 6 needs to be installed, simply pull the pull ring first. At this time, the pull ring will drive the outer plate 27 to move together. The outer plate 27 moves, and the outer plate 27 then moves the contact plate 25 synchronously on the outer wall of the slide rod 24. During the movement of the contact plate 25, it will squeeze the return spring 26. The contact plate 25 will also move the insertion rod 28 synchronously. At this time, the insertion plate 17 is inserted into the positioning frame 22, and then the pull ring is released. At this time, the return spring 26 is reset, and the contact plate 25 and the insertion rod 28 move synchronously. When the insertion rod 28 is inserted into the slot on the surface of the insertion plate 17, the insertion plate 17 and the positioning frame 22 can be fixed. At this time, the dust cover 6 can be installed, and it is convenient for the staff to disassemble, replace and clean the dust cover 6.

[0027] In one embodiment, such as Figure 3 and Figure 6 As shown, the adjustment assembly includes an adjustment plate 29 fixedly installed on the surfaces of two side plates 2. A bidirectional threaded rod 30 is rotatably connected to the inner wall of the adjustment plate 29. The other end of the bidirectional threaded rod 30 extends to the outside of the adjustment plate 29 and is fixedly connected to a knob 18. Threaded blocks 31 are symmetrically threaded to the outer wall of the bidirectional threaded rod 30. The surfaces of the adjustment plate 29 and the side plates 2 are provided with grooves for the threaded blocks 31 to move. The surfaces of the four threaded blocks 31 are fixedly connected to the surfaces of the four connecting plates 4. When it is necessary to adjust the spacing of the guide rollers 3, simply rotate the knob 18. At this time, the knob 18 will drive the bidirectional threaded rod 30 to rotate synchronously. The threaded blocks 31 will move synchronously on the outer wall of the bidirectional threaded rod 30, driving the four connecting plates 4 to move synchronously. The connecting plates 4 will then drive the guide rollers 3 to move synchronously. At this time, the spacing of the guide rollers 3 can be adjusted, so that the guide rollers 3 can effectively guide and flatten packaging films of different thicknesses.

[0028] In one embodiment, such as Figure 4As shown, support blocks 19 are symmetrically installed on the surfaces of the other two side plates 2. A guide rod 20 is fixedly connected between each pair of support blocks 19. A guide block 21 is slidably connected to the outer wall of the guide rod 20. Guide grooves for the guide blocks 21 to move are opened on the surfaces of the other two side plates 2. The surfaces of the four guide blocks 21 are fixedly connected to the surfaces of the other four connecting plates 4 respectively. During the movement of the guide roller 3, it will also drive the other four connecting plates 4 to move synchronously. The other four connecting plates 4 will then drive the guide blocks 21 to move synchronously on the outer wall of the guide rod 20. At this time, the guide blocks 21 and the guide rod 20 can effectively play a limiting and guiding role, thereby effectively improving the stability of the guide roller 3 during the movement.

[0029] In one embodiment, such as Figures 1-6 As shown, a scale 33 is fixedly connected to the surface of the adjusting plate 29, and an indicator needle 32 that cooperates with the scale 33 is fixedly installed on the surface of multiple threaded blocks 31. When the threaded blocks 31 move, they will also drive the indicator needle 32 to move synchronously. At this time, the operator can check the spacing of the guide roller 3 by the cooperation between the indicator needle 32 and the scale 33, so as to adjust the spacing of the guide roller 3 more accurately.

[0030] The above embodiment discloses a cooling structure for hot melt adhesive packaging film production. When cooling of the packaging film is required, one end of the film is simply passed through multiple guide rollers 3 and the interior of the cooling box 1, and wound onto an external winding device. At this time, the inlet fan 7 starts operating, effectively blowing air from the external environment into the cooling box 1. This air is then blown onto the upper and lower surfaces of the packaging film, effectively cooling both surfaces. During the operation of the inlet fan 7, the liquid pump 10 also starts operating simultaneously. The liquid pump 10 and the coolant in the serpentine cooling pipe 9 effectively cool the air from the external environment. The cooling process allows the inlet fan 7 to effectively blow cold air onto the upper and lower surfaces of the packaging film, further improving the cooling efficiency and effect. The dustproof mesh cover 6 effectively prevents the inlet fan 7 from drawing dust and other impurities from the external environment into the cooling box 1, further improving the production quality of the packaging film. When the spacing of the guide rollers 3 needs to be adjusted according to the actual thickness of the packaging film, the spacing can be conveniently and effectively adjusted by the interaction between the knob 18 and the bidirectional threaded rod 30. This allows the guide rollers 3 to effectively guide and flatten packaging films of different thicknesses, further enhancing the overall practicality and adjustment flexibility of the device.
