Description

Technical Field

[0001] This utility model relates to the field of wear-resistant wire drawing transfer film technology, specifically to a coating oven for wear-resistant wire drawing transfer film. Background Technology

[0002] Abrasion-resistant brushed transfer film is a functional thin film material, typically based on polyester film (PET), which possesses good strength, flexibility, and dimensional stability. A functional coating is applied to the substrate using processes such as coating. These coatings contain abrasion-resistant materials and components that achieve the brushed effect, together forming the abrasion-resistant brushed transfer film. After special surface treatment, it exhibits a brushed metal-like texture, possessing a unique aesthetic appeal. It can present different styles of brushed visual effects, such as delicate or rugged, adding a unique decorative touch to products.

[0003] During the coating process, abrasion-resistant wire-drawing transfer films are coated with various functional coatings, adhesives, and other substances, which often contain solvents. Coating ovens provide a suitable high-temperature environment, promoting rapid solvent evaporation and allowing the coating to dry and cure.

[0004] Coating ovens consume a lot of energy to generate hot air to dry the transfer film during operation. However, most existing coating ovens do not have the function of waste heat recovery and need to continuously reheat the air entering the oven. This method increases production and operating costs. To address this, we provide a coating oven for wear-resistant filament transfer films. Utility Model Content

[0005] The purpose of this invention is to provide a coating oven for wear-resistant wire drawing transfer film to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A coating oven for abrasion-resistant wire-drawing transfer film includes an oven, an interior of which a transfer film is disposed, and a support plate is fixedly installed on both outer surfaces of the oven. A water storage tank is fixedly installed on the bottom end of the support plate.

[0008] Waste heat recovery units are provided on both sides of the oven, and a filter unit is provided on the top of the support plate.

[0009] The filtration unit includes a filter box fixedly installed on the top of the support plate, the bottom end of the filter box extending into the top of the water storage tank, and a filter frame fixedly installed inside the filter box.

[0010] The waste heat recovery unit includes recovery pipes fixedly installed inside the shells on both sides of the oven, with the other end of the recovery pipes penetrating the filter box and extending inside the filter frame.

[0011] A further improvement of this utility model is that: a fan is fixedly installed on the connecting pipes on both sides of the filter box, an air guide pipe is fixedly installed on the top of the fan, and a heating box is fixedly installed on the other end of the air guide pipe.

[0012] A further improvement of this utility model is that the heating box is fixedly installed on the top of the oven, and an electric heating tube is fixedly installed inside the heating box.

[0013] A further improvement of this utility model is that: a heat exhaust pipe is fixedly installed on the output end of the heating box, and the other end of the heat exhaust pipe penetrates the top shell of the oven and is fixedly installed with a heat exhaust cover. The heat exhaust cover is fixedly installed at the top of the inner walls on both sides of the oven. Multiple sets of heat exhaust covers are provided to facilitate the flow of hot air to the transfer film that penetrates into the oven, thereby promoting the drying of the transfer film.

[0014] A further improvement of this utility model is that a circulation pump is fixedly installed on the outside of the water storage tank, a liquid extraction pipe is fixedly installed on the input end of the circulation pump, and the other end of the liquid extraction pipe is fixedly installed inside the water storage tank.

[0015] A further improvement of this utility model is that: a drain pipe is fixedly installed on the output end of the circulating pump, a diverter pipe is fixedly installed on the other end of the drain pipe, a spray plate is fixedly installed on the other end of the diverter pipe, and the spray plate is fixedly installed inside the top shell of the filter box.

[0016] A further improvement of this utility model is that: a drying plate is provided at the through holes on both sides of the filter box, and a separation mesh frame is movably inserted into one side of the water storage tank. The separation mesh frame can filter the downward flowing liquid, so that impurities in the liquid can be separated.

[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0018] This invention provides a coating oven for wear-resistant wire-drawing transfer films. A fan draws airflow from inside the oven into a filter box via a recovery pipe, and then, through a duct, transports the airflow to the interior of a heating chamber. An electric heating element heats the airflow, which, after heating, re-enters the oven via an exhaust pipe and hood. As the transfer film passes through the oven's interior, it is dried by the hot airflow. Furthermore, the hot airflow, upon contact with the transfer film, re-enters the recovery pipe under the fan's influence, achieving the goal of recycling the hot airflow. Over the long term, this can save on production and operating costs.

[0019] This utility model provides a coating oven for wear-resistant wire drawing transfer film. By setting up a filter box and a filter frame, the airflow enters the interior of the filter box in conjunction with the recovery pipe, and can be filtered by the filter frame to prevent impurities from being mixed in the airflow, thereby improving the drying quality.

[0020] This invention provides a coating oven for wear-resistant wire-drawing transfer film. By setting up a circulation pump and a liquid extraction pipe, liquid inside the water storage tank can be drawn out and transported to the inside of the spray plate through the drain pipe. The spray plate sprays the liquid downwards, so that the liquid is sprayed onto the filter frame, cleaning the impurities attached to the filter frame and causing them to merge with the liquid and flow downwards into the water storage tank. The filter is then filtered by a separating mesh frame, causing the impurities to be retained inside the mesh frame. The liquid then re-enters the water storage tank for reuse. This allows the filter frame to be cleaned after the drying process is complete. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0028] like Figure 1-5 As shown, this utility model provides a coating oven for wear-resistant wire-drawing transfer film, including an oven 1, a transfer film 2 disposed inside the oven 1, a support plate 3 fixedly installed on both outer surfaces of the oven 1, a water storage tank 4 fixedly installed on the bottom end of the support plate 3, a waste heat recovery unit disposed on both sides of the oven 1, and a filter unit disposed on the top of the support plate 3. The waste heat recovery unit includes a recovery pipe 42 fixedly installed inside the shells on both sides of the oven 1, and the other end of the recovery pipe 42 penetrates through the filter box 41 and extends inside the filter frame 411. Fans 43 are fixedly installed on the connecting pipes on both sides of the filter box 41. A guide pipe 44 is fixedly installed on the top of the fan 43. A heating box 45 is fixedly installed on the other end of the guide pipe 44. The heating box 45 is fixedly installed on the top of the oven 1. An electric heating tube 451 is fixedly installed inside the heating box 45. A heat exhaust pipe 46 is fixedly installed on the output end of the heating box 45. The other end of the heat exhaust pipe 46 penetrates the top shell of the oven 1 and is fixedly installed with a heat exhaust cover 47. The heat exhaust cover 47 is fixedly installed at the top of the inner walls on both sides of the oven 1.

[0029] Furthermore, the airflow inside the oven 1 is drawn into the filter box 41 by the fan 43 and the recovery pipe 42, and then transported to the interior of the heating box 45 by the air guide pipe 44. The airflow enters the interior of the heating box 45 and is heated by the electric heating tube 451. After being heated, the airflow enters the interior of the oven 1 again by the heat exhaust pipe 46 and the heat exhaust hood 47. When the transfer film passes through the inside of the oven 1, it can be dried by the hot airflow. After the hot airflow comes into contact with the transfer film, it can re-enter the recovery pipe 42 under the action of the fan 43, thus realizing the purpose of recycling the hot airflow. Example

[0030] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the filter unit includes a filter box 41 fixedly installed on the top of the support plate 3, the bottom end of the filter box 41 extends into the top of the water storage tank 4, a filter frame 411 is fixedly installed inside the filter box 41, a circulation pump 412 is fixedly installed on the outside of the water storage tank 4, a liquid extraction pipe 413 is fixedly installed on the input end of the circulation pump 412, the other end of the liquid extraction pipe 413 is fixedly installed inside the water storage tank 4, a drain pipe 414 is fixedly installed on the output end of the circulation pump 412, a diversion pipe 415 is fixedly installed on the other end of the drain pipe 414, a spray plate 416 is fixedly installed on the other end of the diversion pipe 415, the spray plate 416 is fixedly installed inside the top shell of the filter box 41, a drying plate 417 is provided at the through holes on both sides of the filter box 41, and a separation mesh frame 418 is movably inserted into one side of the water storage tank 4.

[0031] Furthermore, the airflow, in conjunction with the recovery pipe 42, enters the interior of the filter box 41, where it is filtered by the filter frame 411 to prevent impurities from entering the airflow. After drying, the circulation pump 412, in conjunction with the liquid extraction pipe 413, draws the liquid from the water storage tank 4 outwards and, with the drain pipe 414, transports it to the interior of the spray plate 416. The spray plate 416 sprays the liquid downwards onto the filter frame 411, cleaning the impurities attached to the filter frame 411 and causing them to merge with the liquid and flow downwards into the water storage tank 4. There, it is filtered by the separation mesh frame 418, causing the impurities to remain inside the mesh frame, while the liquid re-enters the water storage tank 4 for reuse.

[0032] The working principle of the coating oven for this wear-resistant wire-drawing transfer film will be explained in detail below.

[0033] like Figure 1-5As shown, during use, the fan 43 generates suction, which draws the airflow inside the oven 1 into the filter box 41 via the recovery pipe 42. The airflow is then transported to the heating box 45 via the air duct 44. Inside the heating box 45, the airflow is heated by the electric heating element 451. After heating, the airflow re-enters the oven 1 via the heat exhaust pipe 46 and heat exhaust hood 47. When the transfer membrane passes through the inside of the oven 1, it is dried by the hot airflow. After contacting the transfer membrane, the hot airflow re-enters the recovery pipe 42 under the action of the fan 43, achieving the purpose of recycling the hot airflow. 42 enters the interior of the filter box 41, where it can be filtered with the filter frame 411 to prevent impurities in the airflow. After drying, the liquid inside the water storage tank 4 can be drawn out by starting the circulation pump 412 and the liquid extraction pipe 413, and transported to the interior of the spray plate 416 with the drain pipe 414. The spray plate 416 sprays the liquid downward, so that the liquid is sprayed on the filter frame 411, cleaning the impurities attached to the inside of the filter frame 411, and making them merge with the liquid and flow downward into the interior of the water storage tank 4. It is then filtered with the separation mesh frame 418, so that the impurities are retained inside the mesh frame, and the liquid re-enters the water storage tank 4 for reuse.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
