Description

Technical Field

[0001] This utility model relates to the technical field of color film processing equipment, specifically a coating machine for PVC color film processing. Background Technology

[0002] Colored film is a new type of tempered glass decorative material. It breaks away from the traditional process of using tempered photo-printing materials for glass decoration, thus replacing them and dominating the market for glass sliding doors, glass cabinets, glass background walls, and other glass decorative materials. Finished glass products made with colored film have high safety. When such glass products are broken, the glass fragments do not scatter like ordinary glass; instead, all the fragments adhere to the colored film, ensuring user safety in case of breakage. Furthermore, tempered glass colored film is highly environmentally friendly. The colored film processing requires the use of a coating machine.

[0003] The existing coating machines for color film processing have the following drawbacks during use: After the color film is coated, it needs to be sent to a drying oven to dry the coating. However, the heat in the drying oven only dries the color film, resulting in low utilization. Therefore, there is room for improvement. Utility Model Content

[0005] Therefore, the technical solution adopted by this utility model is as follows: a coating machine for PVC color film processing, comprising: a main body and a drying and preheating mechanism, wherein the main body includes a base plate, a paint box fixed to the top of the base plate, a coating component rotatably mounted on the paint box, a scraping roller rotatably mounted on the paint box, and two first guide rollers fixed on the base plate.

[0006] The drying and preheating mechanism includes a box fixed to the top of the base plate, multiple symmetrically arranged and staggered rotating rollers installed on the inner wall of the box, second guide rollers symmetrically and rotatably installed on the inner wall of the box, a drying box fixed to the top of the box, multiple electric heating tubes fixed in an array on the inner top wall of the drying box, first air ducts symmetrically fixed on both sides of the drying box, second air ducts symmetrically fixed on both sides of the box, and an air supply component connecting the first air duct and the second air duct.

[0007] In a preferred embodiment, the present invention can be further configured such that the air supply component includes a pipe body fixed to the end of a first duct and communicating with the inner cavity of the first duct, a corrugated pipe with one end connected to the pipe body and the other end connected to a second duct, and a high-speed fan installed on the inner wall of the pipe body.

[0008] In a preferred embodiment, this invention can be further configured such that the high-speed fans inside the air supply components on both sides face opposite directions.

[0009] In a preferred embodiment, the present invention can be further configured such that the coating component includes a coating roller rotatably mounted on a paint tank and a motor fixed to one side of the paint tank with its shaft fixedly connected to the coating roller.

[0010] In a preferred embodiment, the present invention can be further configured such that: the color film is introduced from the second guide roller on one side of the chamber, passes around multiple rotating rollers in sequence, and is then sent out through the second guide roller on the other side, passing around the coating roller, the leveling roller, and the first guide roller in sequence, and finally sent into the drying chamber.

[0011] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1.

[0015] 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 specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0016] Some embodiments of this utility model are described below with reference to the accompanying drawings. Example 1: Combination Figure 1-4 As shown, this embodiment provides a coating machine for PVC color film processing, including: a main body 100 and a drying and preheating mechanism 200.

[0017] The main structure 100 includes a base plate 110, a paint tank 120 fixed to the top of the base plate 110, a coating component 130 rotatably mounted on the paint tank 120, a leveling roller 140 rotatably mounted on the paint tank 120, and two first guide rollers 150 fixed on the base plate 110.

[0018] The base plate 110 is used to fix other components and ensure the stability of each component structure. The paint tank 120 is used to fill paint. The coating component 130 is used to apply paint to the surface of the color film. It includes a coating roller 131 rotatably mounted on the paint tank 120 and a motor 132 fixed on one side of the paint tank 120 and whose shaft is fixedly connected to the coating roller 131. One side of the coating roller 131 is immersed in the paint in the paint tank 120. The color film passes around the coating roller 131. When the motor 132 drives the coating roller 131 to rotate, the coating roller 131 applies the paint adhering to its surface to the surface of the color film. Then the color film passes through the scraping roller 140, which scrapes the paint on the surface of the color film.

[0019] Two first guide tubes are provided to introduce the coated film into the drying oven 240, with the coated surface of the film facing upwards.

[0020] The drying and preheating mechanism 200 is used to dry the coating on the surface of the color film. It includes a box 210 fixed to the top of the base plate 110, a plurality of symmetrically arranged and interlaced rotating rollers 220 installed on the inner wall of the box 210, a second guide roller 230 symmetrically and rotatably installed on the inner wall of the box 210, a drying box 240 fixed to the top of the box 210, a plurality of electric heating tubes 250 fixed in an array on the inner top wall of the drying box 240, a first air duct 260 symmetrically fixed on both sides of the drying box 240, a second air duct 270 symmetrically fixed on both sides of the box 210, and an air supply component 280 connecting the first air duct 260 and the second air duct 270.

[0021] The housing 210 is fixed to the top of the base plate 110 and is made of thermal insulation material to form a closed environment. Rectangular holes are opened on both sides of the housing 210 to facilitate the feeding and feeding of the color film. The rotating rollers 220 are symmetrically and staggered. The second guide roller 230 is used to introduce and guide the color film. The color film is introduced from the second guide roller 230 on one side of the housing 210, passes around multiple rotating rollers 220 in turn, and is then fed out through the second guide roller 230 on the other side. This can effectively extend the time that the color film stays in the housing 210, so that the color film can be fully preheated.

[0022] The heating tubes 250 are fixed in an array on the inner top wall of the drying oven 240 to increase the temperature inside the drying oven 240, so as to facilitate the drying of the coating on the surface of the color film.

[0023] The first air duct 260 is connected to the inner cavity of the drying chamber 240, and the second air duct 270 is connected to the inner cavity of the housing 210. The air supply component 280 is used to circulate the air in the drying chamber 240 and the housing 210, thereby increasing the temperature inside the housing 210 and facilitating the preheating of the color film. The air supply component 280 includes a pipe body 281 fixed to the end of the first air duct 260 and connected to the inner cavity of the first air duct 260, a corrugated pipe 282 with one end connected to the pipe body 281 and the other end connected to the second air duct 270, and a corrugated pipe 282 installed on the pipe body 281. The high-speed fan 283 is mounted on the inner wall. The pipe body 281 is used to install the high-speed fan 283. The corrugated pipe 282 facilitates the flow of hot air. The high-speed fans 283 in the air supply components 280 on both sides face opposite directions. With this setting, the air supply component 280 on one side sends the hot air in the drying oven 240 into the box body 210 to increase the temperature of the inner cavity of the box body 210. The air supply component 280 on the other side sends the hot air in the inner cavity of the box body 210 back into the drying oven 240, forming a circulation and ensuring the stability of the temperature inside the box body 210.

[0024] The working principle and usage process of this utility model are as follows: In use, the colored film is fed into the inner cavity of the box 210, introduced from the second guide roller 230 on one side of the box 210, and sequentially passes around multiple rotating rollers 220. Then it is sent out through the second guide roller 230 on the other side, sequentially passing around the coating roller 131, the scraping roller 140, and the first guide roller 150, and finally sent into the drying box 240. The electric heating tube 250 in the drying box 240 is activated to dry the coating on the colored film. At the same time, the air supply component 280 on one side is activated to extract the hot air in the drying box 240 and send it into the box 210 to raise the temperature of the inner cavity of the box 210 and preheat the colored film before coating. The air supply component 280 on the other side then sends the air in the box 210 into the drying box 240 to form a cycle.

[0025] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
