Description

Technical Field

[0001] The utility model belongs to the technical field of decorative film production equipment, and particularly relates to a decorative film cooling device. Background Art

[0002] A decorative film is a decorative material prepared from a polymer as a raw material, adding functional additives, and through calendering and compounding. In the production process of decorative films, it is necessary to cool and shape the decorative film. The existing cooling method usually directly contacts the decorative film with cooling water for cooling. However, this method easily causes water droplets to remain on the decorative film, resulting in problems in the subsequent winding process.

[0003] Another existing cooling method is to cool the decorative film through a cooling roller filled with coolant inside. However, in the actual operation process, it is easy to cause uneven cooling on the film surface. Especially when the width of the film is relatively large, it may cause problems such as warping and deformation of the film.

[0004] Therefore, a decorative film cooling device that can balance uniform film cooling and is not prone to water droplet residue is needed. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problems of uneven cooling and easy water droplet residue of the decorative film cooling device described in the above background art. Here, a new decorative film cooling device is proposed, which can balance uniform cooling of the decorative film and reduce water droplet residue.

[0006] The technical solution adopted to achieve the above purpose is a decorative film cooling device, which includes:

[0007] A cooling unit, which includes a cooling box body, a first cooling roller, two first guide rollers, two second guide rollers, two atomization units, two purging units, and two water baffle plates. The first cooling roller, two first guide rollers, and two second guide rollers are rotatably connected to the cooling box body. The two purging units are respectively fixed on the opposite inner walls of the cooling box body. The two water baffle plates are respectively fixed on the opposite inner walls of the cooling box body. The two atomization units are respectively fixed at the bottom of the top wall of the cooling box body and the bottom of one of the water baffle plates. A first inlet is provided on one side of the cooling box body, and a first outlet is provided on the other side of the cooling box body. The atomization unit includes a liquid inlet pipe, a plurality of branched liquid outlet pipes, and a plurality of spray heads. The plurality of branched liquid outlet pipes are communicated with the liquid inlet pipe, and the end of the branched liquid outlet pipe is connected to the spray head;

[0008] Drying unit, the drying unit includes a drying box body, a plurality of drying rollers and a plurality of fans. One side of the drying box body is provided with a second inlet, and the other side of the drying box body is provided with a second outlet. The second inlet is communicated with the first outlet. The plurality of drying rollers are rotatably connected to the drying box body. The top wall and the bottom wall of the drying box body are provided with a plurality of installation grooves, and the fans are arranged in the installation grooves;

[0009] Rewinding unit, the rewinding unit includes a bracket and a rewinding roller, and the bracket is rotatably connected to the rewinding roller.

[0010] In the above technical solution, the decorative film sequentially passes through the first cooling roller, two first guiding rollers and two second guiding rollers. The cooling liquid is sprayed onto the surface of the decorative film in the form of an atomized liquid by the atomizing unit, and through the purging unit, the atomized liquid on the surface of the decorative film is blown off to prevent it from aggregating into water droplets. When the decorative film reaches the drying unit, the residual liquid is dried by the fans.

[0011] Further, the purging unit includes an air inlet pipe, a plurality of branch air pipes and a plurality of air nozzles. The air inlet pipe is communicated with the plurality of branch air pipes, and the end of the branch air pipe is connected to the air nozzle.

[0012] Further, the air nozzle is arranged to incline downward.

[0013] In the above technical solution, by blowing air obliquely downward, the liquid on the surface of the decorative film is blown off and falls on the water baffle, which can fully prevent the water droplets from aggregating.

[0014] Further, the water baffle is provided with two openings, and the two openings are located at the two side edges of the water baffle.

[0015] In the above technical solution, through the openings, the liquid aggregated on the water baffle is discharged and falls to the bottom of the cooling box body.

[0016] Further, the cooling unit further includes two water absorbing rollers, and the two water absorbing rollers are rotatably connected to the cooling box body.

[0017] Further, the outer part of the water absorbing roller is sleeved with a water absorbing sponge.

[0018] In the above technical solution, after the liquid on the surface of the decorative film is blown off by the purging unit, the liquid is further absorbed by the water absorbing sponge.

[0019] Further, the first cooling roller, the two first guiding rollers, the two second guiding rollers and the water absorbing roller are arranged in an "S" shape. One water baffle is located between the first cooling roller and the second guiding roller, and the other water baffle is located between the first guiding roller and the water absorbing roller.

[0020] In the above technical solution, through this setting, firstly, the cooling path of the decorative film is extended to fully cool the decorative film; secondly, both sides of the decorative film are subjected to coolant spray cooling treatment to make the cooling uniform and prevent wrinkles and other conditions from occurring on the decorative film.

[0021] Furthermore, the plurality of drying rollers are arranged in a wavy distribution.

[0022] In the above technical solution, by the above setting, the drying path is extended to fully volatilize the residual liquid on the surface of the decorative film.

[0023] Furthermore, a drain valve is provided at the bottom of the cooling box body.

[0024] The advantages of the present utility model are as follows:

[0025] 1. The present utility model uses an atomizing nozzle to spray atomized liquid to cool the decorative film. Compared with using spray cooling, the water consumption is less, and the liquid droplets of the atomized liquid are smaller, making it easier to blow off and less likely to aggregate into larger liquid droplets when purged by the purging unit subsequently.

[0026] 2. The first cooling roller, two first guiding rollers, two second guiding rollers and the water absorbing roller of the present utility model are arranged in an "S" shape, so that both sides of the decorative film need to be atomized and cooled, making the cooling more uniform and ensuring that the humidity on both sides is maintained in balance. Finally, quality problems such as wrinkles are not likely to occur on the decorative film. BRIEF DESCRIPTION OF THE DRAWINGS
