Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, and in particular to flat plate coating machines. Background Technology

[0002] Currently, flatbed coating machines use backplate heating, which requires the heat to be transferred to the coating material above by coating the substrate. When the contact between the substrate and the backplate is uneven, it is easy to cause different temperatures, different drying conditions, and slow heating of the coating material when the substrate is thick. Summary of the Invention

[0003] The purpose of this invention is to provide a small flatbed coating machine that effectively solves the above-mentioned technical problems, has a simple structure, and is easy to implement.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A small flat plate coating machine, comprising:

[0006] A base that extends horizontally, and a coating platform that is erected on the upper side of the base. The coating platform extends horizontally along with the base and is used to support the substrate to be coated.

[0007] The control module is mounted on the base and located at one end of the coating platform. The control module contains a servo motor system.

[0008] A scraper holder is mounted on a base and located on the upper side of the coating platform. The scraper holder is connected to the servo motor system of the control module via a synchronous belt. The scraper holder has a pre-reserved interface for scraper installation, so that the scraper can be installed on the scraper holder. Driven by the servo motor system, the scraper holder moves along the extension direction of the coating platform, and the scraper follows the movement of the scraper holder to perform the scraping work, so that the substrate is coated with paint.

[0009] An oven, which is fitted onto a coating platform and provides hot air for baking, to dry the coating applied to the substrate.

[0010] The above solution is further described in that one side of the oven is hinged to the base via a hinge, so that the other side of the oven can open and close relative to the base; the oven is provided with a cover, which covers the coating platform when the oven is closed, and the cover is provided with an air inlet and an air return outlet.

[0011] The above-mentioned solution is further described in that the air inlet is located in the middle of the inner bottom of the cover opening, while the air return outlet is located on the inner circumferential side of the cover opening.

[0012] The above solution is further described in that the oven and the control module are respectively located at the two ends of the coating platform in the extension direction. When the oven is closed, there is a buffer space between it and the control module. This buffer space is adapted to the temporary storage of the scraper bracket and the establishment of the starting position for the scraping operation.

[0013] A further aspect of the above scheme is that the coating platform is provided with an array of negative pressure holes, which are connected to a vacuum pumping device through pipes. The negative pressure holes are distributed at least in the area covered by the mask so that the substrate can be adsorbed onto the coating platform.

[0014] Furthermore, the above solution includes a manual pressing mechanism in the buffer space, which is used to press the substrate placed on the coating platform.

[0015] A further improvement in the above scheme is that the scraper support is a flat, square-shaped structure, and the scraper support is connected to the coating platform through an internal hollow section.

[0016] A further improvement of the above scheme is that the coating platform is provided with a return trough, which is a partially recessed structure of the coating platform, and the return trough is used to collect excess coating that has been scraped out.

[0017] This invention integrates an oven into a flatbed coating machine. The oven is fitted onto the coating platform and provides hot air for baking, thus drying the coating on the substrate online. This achieves direct heating of the coating on the substrate by the hot air, resulting in a temperature close to the actual temperature. This reduces intermediate transfer links, leads to faster drying, and ensures even heating of the coating. It is suitable for heating and drying coatings of various substrate thicknesses. Furthermore, the fan speed and heating speed can be adjusted to control temperature changes, improving practicality.

[0018] Another advantage of this utility model is its simple structure, small size, and ease of implementation. Attached Figure Description

[0022] The following will further explain the concept, specific structure and technical effects of the utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the utility model.

[0023] It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0024] See Figure 1 , 2 Figure 3 shows a schematic diagram of a preferred embodiment of the present invention. The present invention relates to a small flat plate coating machine, which includes: a base 1, a control module 2, a scraper bracket 3, and an oven 4.

[0025] The base 1 extends horizontally, and a coating platform 11 is erected on its upper side. The coating platform 11 extends horizontally along with the base and is used to support the substrate to be coated. A control module 2 is mounted on the base 1 and located at one end of the coating platform 11. This control module 2 includes a servo motor system 21. A scraper bracket 3 is mounted on the base 1 and located on the upper side of the coating platform 11, and is connected to the servo motor system 21 of the control module 2 via a synchronous belt 31. The scraper bracket 3 has a pre-reserved flexible interface 32 for scraper installation. Driven by the servo motor system 21, the scraper bracket 3 moves along the extension direction of the coating platform, and the scraper follows the movement of the scraper bracket 3 to perform the coating process, applying paint to the substrate. An oven 4 is fitted over the coating platform 11 and provides hot air for online drying of the paint applied to the substrate.

[0026] In this embodiment, one side of the oven 4 is hinged to the base 1 via a hinge 5, allowing the other side of the oven 4 to open and close relative to the base. The oven 4 is provided with a cover 41, which covers the coating platform 11 when the oven 4 is closed. The cover 41 has an air inlet 411 and an air return outlet 412 inside. Preferably, the air inlet 411 is located in the middle of the inner bottom of the cover 41 and is equipped with a corresponding fan, while the air return outlet 412 is located on the inner circumferential side of the cover 41, forming a circulating heating mode. Specifically, the hot air generation and energy recovery and reuse of the oven 4 are existing technologies and will not be described in detail here. By directly integrating an oven 4 onto the flatbed coating machine, the oven covers the coating platform and provides hot air for baking, thus drying the coating applied to the substrate. This achieves direct heating of the coating applied above the substrate by hot air, resulting in a temperature close to the actual temperature, reducing intermediate transfer links, fast drying, and even heating of the coating. It is suitable for heating and drying coatings of various substrate thicknesses. Furthermore, the fan speed and heating speed can be adjusted to control temperature changes, improving practicality.

[0027] In this embodiment, the oven 4 and the control module 2 are respectively located at the two ends of the coating platform's extension direction, making full use of the limited space, resulting in a compact and reasonable structure, miniaturization, and ease of use. When the oven 4 is closed, a buffer space 6 is left between it and the control module 2. This buffer space 6 is adapted to temporarily store the scraper bracket 3 and establish the starting position for the scraping operation. In this embodiment, the scraper bracket 3 can pause in the buffer space 6, effectively avoiding obstruction and facilitating the oven 4's closing and drying operation. In this embodiment, the scraper bracket 3 drives the scraper to begin the scraping operation from the buffer space 6, continuing to scrape away from the control module 2, i.e., the end of the scraping is close to the hinged side of the oven 4. In this embodiment, the coating platform 11 is provided with a return trough 112. This return trough 112 is a partially recessed structure of the coating platform, close to the hinged side of the oven 4. The return trough 112 is used to collect excess coating material scraped out, reducing waste and also contributing to uniform coating.

[0028] In this embodiment, the coating platform 11 is provided with an array of negative pressure holes 111. The negative pressure holes 111 are connected to the vacuum equipment 7 through pipes. The negative pressure holes 111 are distributed at least in the area covered by the cover 41 so that the substrate can be adsorbed on the coating platform 11. This not only facilitates smooth coating but also effectively flattens the substrate, which is beneficial for subsequent drying operations. The coating is heated evenly and dries quickly.

[0029] In this embodiment, the buffer space 6 is further provided with a manual pressing mechanism 8, which is used to press the substrate placed on the coating platform 11, further improving the substrate placement and fixation effect, and facilitating the coating process. The manual pressing mechanism 8 includes a pressure plate and a quick-release clamp connecting the pressure plate, which has a simple structure and is easy to operate.

[0030] In this embodiment, the scraper support 3 is a flat, square shape. The scraper support 3 is connected to the coating platform 11 through its internal hollow part. The symmetrical structure helps to improve the stability of movement.

[0031] During operation, the substrate to be coated is laid flat on the coating platform 11. Then, the manual pressing mechanism 8 is used to press one end of the substrate firmly. The vacuum equipment 7 is activated, and the substrate is drawn in through the negative pressure holes 111, ensuring it is flat and tightly adhered to the coating platform 11. Next, the scraper is installed on the scraper holder 3, using the quick-release mechanism 32 (a slotted joint) for rapid alignment and installation. The scraper is adjusted to the desired coating thickness, and then the coating material is poured onto the substrate. The servo motor system 21 on the control module 2 is activated. The servo motor system 21 drives the scraper holder 3 to move along the extension direction of the coating platform via the synchronous belt 31. The scraper follows the movement of the scraper holder 3 to perform the coating process, thus coating the substrate. After coating is complete, the scraper is removed, and the oven 4 is closed and heating begins. The temperature is maintained at the preset temperature for a certain period to dry the coating on the substrate, completing the coating process.

[0032] This invention features a simple structure, small size, and ease of implementation. It integrates an oven into a flatbed coating machine, directly heating the coating applied to the substrate online at temperatures close to the actual temperature. This reduces intermediate heat transfer steps, resulting in rapid drying and even heating of the coating. It is suitable for heating and drying coatings of various substrate thicknesses, making it highly practical.

[0033] While the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention should not be limited to the same structure and operation as described above and the accompanying drawings. For those skilled in the art, many equivalent improvements and variations can be made to the above embodiments through logical analysis, reasoning or limited experiments without exceeding the concept and scope of the present invention, but these improvements and variations should all fall within the scope of protection claimed by the present invention.
