Description

Technical Field

[0001] The utility model relates to the technical field of hot melt adhesive film production equipment, in particular to a cooling device for hot melt adhesive film production. Background Art

[0002] Hot melt adhesive film is a film product with or without release paper. It can be easily operated continuously or intermittently and can be widely used for bonding various fabrics, paper, polymer materials and metals. Hot melt adhesive film is divided into two categories: thermoplastic and thermosetting according to its usage characteristics.

[0003] After searching, it was found that the publication number is CN213082072U, and the name is a cooling device for hot melt adhesive film production. The application proposes that the hot melt adhesive film needs to be cooled and formed after it is formed, but the traditional cooling device has a simple structure, and the cooling effect is not good during cooling, which will affect the forming of the hot melt adhesive film and cause material waste, and the cooling water will be directly discharged after use, wasting a lot of water resources and high cost. By setting a drainage box, after the hot melt adhesive film is produced, the formed hot melt adhesive film is transported from the right conveying pipe to the inside of the cooling box, and then passes through the bottom of the rotating shaft, and then output through the left conveying pipe. When the hot melt adhesive film passes through the conveying pipe, it will pass between the pressing wheel and the transmission wheel. The pressing wheel will flatten and sort the surface of the hot melt adhesive film, which plays a certain role in the forming of the hot melt adhesive film, so that the surface of the hot melt adhesive film after forming and cooling will not be The wind generated by the fan starting up will blow into the interior of the refrigeration box from the jack to cool the connecting pipe, and the cooled water can be recycled, which saves water resources and reduces the production cost of the hot melt adhesive film. However, the application adopts water cooling to cool the hot melt adhesive film. When water contacts the hot melt adhesive film, some water stains will remain on the hot melt adhesive film, which will cause the hot melt adhesive film to be damp in the later stage, making it inconvenient to directly reel up the film, affecting work efficiency. At the same time, the strength of the hot melt adhesive film is low before cooling, and flattening and finishing at this time may easily cause it to be damaged, affecting the yield rate, and further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

Subsequently, the hot-melt adhesive film passes through the water-absorbing sponge cover 17, and the first driving motor 14 drives the water-absorbing sponge cover 17 to rotate, and absorbs the residual water on the surface of the hot-melt adhesive film. During the rotation of the water-absorbing sponge cover 17, the water squeezing rod 18 squeezes the water-absorbing sponge cover 17, so that the water in the water-absorbing sponge cover 17 located below directly flows into the bottom of the cooling box 1, and the water in the water-absorbing sponge cover 17 located above flows into the water diversion trough 19 The hot melt adhesive film is kept dry after being cooled, thereby improving the drying efficiency, facilitating the later winding, and improving the working efficiency.

[0034] Working principle:

[0035] When cooling the hot melt adhesive film, the formed hot melt adhesive film can be passed through the inlet and outlet 2 of the cooling box 1, and the industrial water chiller 6 injects cooling water into the water pipe 8, and sprays it on the surface of the hot melt adhesive film through the nozzle 4 and the nozzle 5 to cool the hot melt adhesive film. Subsequently, the hot melt adhesive film passes through the water-absorbing sponge cover 17, and the first driving motor 14 drives the water-absorbing sponge cover 17 to rotate, and absorbs the residual water on the surface of the hot melt adhesive film. During the rotation of the water-absorbing sponge cover 17, the water squeezing rod 18 squeezes the water-absorbing sponge cover 17, so that the water in the water-absorbing sponge cover 17 at the bottom directly flows into the bottom of the cooling box 1, and the water in the water-absorbing sponge cover 17 at the top flows into the water diversion trough 19, and then flows into the bottom of the cooling box 1, so that the water-absorbing sponge cover 17 is always in a constant state. In a saturated state, the water absorption efficiency is maintained. When the hot-melt adhesive film that has been dehydrated passes through the blowing port 11, the blower 9 is started to generate wind force, which is blown out through the air pipe 15 and the blowing port 11 to dry the residual water, so that the hot-melt adhesive film can be kept dry after cooling, thereby improving the drying efficiency, facilitating the later winding, and improving the work efficiency. At the same time, the flattening roller 12 is located behind the blowing port 11. There is a height difference between the flattening roller 12 and the front and rear guide rollers, so that the hot-melt adhesive film can fully contact the flattening roller 12. The flattening roller 12 rotates under the drive of the second driving motor 16 to flatten the cooled hot-melt adhesive film to avoid wrinkles. At the same time, since the hot-melt adhesive film has been cooled at this time, it has high strength and will not be flattened or damaged, thereby improving the yield rate.
