Description

Technical Field

[0001] This utility model relates to the field of sheet metal spraying technology, specifically a coating machine with drying function. Background Technology

[0002] During the processing of door panels, the surface needs to be sprayed to improve their corrosion resistance, weather resistance, aesthetics, and service life. Common coating materials include paint and water-based coatings, and coating equipment is required during the spraying process.

[0003] Utility model patent CN218502433U discloses a coating mechanism for sheet metal. The coating mechanism includes a machine body, a material box fixedly connected to the upper end of the machine body, a coating box within the inner cavity of the machine body, a conveying pipe connecting the coating box and the material box, a cover plate on the right side of the machine body, an electric clamp on the left side wall of the inner cavity of the machine body, and an adjustment assembly between the machine body and the coating box. The adjustment assembly includes an electric slide rail fixedly installed on the inner wall of the machine body, an adjustment box on the outer side of the electric slide rail, a lead screw movably connected to the inner wall of the adjustment box, a movable seat threadedly connected to the outer side of the lead screw, the other end of the movable seat fixedly connected to the coating box, a threaded rod threadedly connected to the side wall of the cover plate, and a stop plate fixedly connected to one end of the threaded rod located within the inner cavity of the machine body. By incorporating an adjustment mechanism, the user can rotate the handle, which in turn rotates the threaded rod. Under the constraints of the sliding hole and the moving seat, the spacing of the spray box can be adjusted, allowing for spraying operations on materials of different thicknesses. The locking pin and locking groove work together to limit the position of the cover plate. Rotating the threaded rod fixes the abutment plate to the material, improving its stability.

[0004] Although the spraying mechanism of this sheet material is convenient for spraying sheets of different thicknesses, the device still has the following problems in actual use: after spraying the sheet material, it needs to be transferred to a drying device for drying, which results in the inability to dry the sheet material in a timely manner, affecting the processing efficiency. Furthermore, the transfer process may also cause contamination of the sprayed surface. Therefore, we propose a coating machine with a drying function. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0030] This embodiment provides a technical solution:

[0031] Please see Figures 1-5 As shown, a coating machine with a drying function includes a machine body 1. The machine body 1 has a feeding hopper 10, a spraying chamber 11, a drying chamber 12 and a discharging hopper 13 arranged sequentially from front to back inside. Multiple partitions 14 are also fixed inside the machine body 1 from front to back. Each partition 14 has a through groove 140 for the material to pass through in the middle. Multiple electric rollers 15 for conveying the material are rotatably installed on the upper and lower sides inside the feeding hopper 10 and the discharging hopper 13. Feed pipes 16 are installed on the upper and lower sides of the spraying chamber 11. Multiple nozzles 17 for spraying the material are installed on the outer walls of the two feed pipes 16.

[0032] The machine body 1 is provided with a drying section 2, which includes two symmetrical shells 20 located in the drying chamber 12. Multiple exhaust slots 200 are provided on the two sides of the two shells 20 that are close to each other. A connecting pipe 201 is fixed at both ends of each shell 20. The end of the connecting pipe 201 away from the shell 20 extends through to the outside of the machine body 1. Hollow air ducts 21 are fixed between the ends of the two connecting pipes 201 on the left and between the ends of the two connecting pipes 201 on the right. A box 22 is fixed between the top ends of the two air ducts 21. The box 22 is located on the top of the outside of the machine body 1. Multiple hot air blowers 23 are installed at the air holes on the top of the box 22.

[0033] The rear end face of the box 22 is provided with a mounting groove 222. The top of the air duct 21 is connected to the mounting groove 222. The rear side of the mounting groove 222 is provided with a cover plate 24. Two side plates 25 inserted into the mounting groove 222 are fixed on the front sides of the cover plate 24 respectively. Multiple positioning strips 251 are fixed on the two sides of the two side plates 25 that are close to each other. Multiple frames 26 distributed in the vertical direction are also provided between the two side plates 25. The ends of the frames 26 are inserted into the gap between the two adjacent positioning strips 251. A dust filter 27 is installed in the opening of the frame 26.

[0034] In this embodiment, ear plates 220 are fixed to both sides of the front end face of the box body 22, and each ear plate 220 is threaded with a fixing bolt 221. A connecting block 250 is fixed to the front end of each side plate 25. The connecting block 250 can pass through the mounting groove 222 and extend to the outer side of the front end of the box body 22. The connecting block 250 has a fixing hole, and the fixing bolt 221 is threaded through the ear plate 220 and inserted into the fixing hole. This design facilitates the disassembly and assembly of the cover plate 24, thereby facilitating the disassembly and cleaning of the dust filter 27.

[0035] In this embodiment, a magnetic strip 260 is fixed to the rear end face of the frame 26, and the magnetic strip 260 is magnetically connected to the front end face of the cover plate 24. The cover plate 24 is made of iron, and the magnetic strip 260 can be magnetically fixed to the cover plate 24. The setting of the magnetic strip 260 further increases the connection stability between the frame 26 and the cover plate 24.

[0036] In this embodiment, the exhaust duct 200 has a rectangular cross-sectional shape, and multiple exhaust ducts 200 are linearly and equally spaced in the horizontal direction. The arrangement of multiple exhaust ducts 200 increases the comprehensiveness and uniformity of airflow, thereby facilitating the uniform drying of the coated surface on the board.

[0037] In this embodiment, the upper and lower nozzles 17 are arranged opposite each other, and the left end of the feed pipe 16 passes through the machine body 1 and extends to the outside. The feed pipe 16 extends to the outside to facilitate connection with the feeding equipment, so that paint and other materials can enter into the feed pipe 16. The upper and lower nozzles 17 are arranged opposite each other, which facilitates simultaneous spraying of the upper and lower surfaces of the door panel.

[0038] In this embodiment, the frame 26 has a U-shaped cross-section, and its dimensions are adapted to the dimensions between the two side plates 25. This design facilitates the stable installation of the frame 26 between the two side plates 25, ensuring the installation stability of the frame 26.

[0039] In this embodiment, the side plate 25 and the connecting block 250 are integrally formed, and the size of the side plate 25 is adapted to the size of the mounting groove 222. The integrally formed side plate 25 and connecting block 250 have better connection strength, ensuring the service life of the side plate 25 and connecting block 250, while the adapted size helps to ensure the installation stability of the cover plate 24.

[0040] In this embodiment, the cover plate 24 has a rectangular cross-sectional shape, and the cross-sectional area of ​​the cover plate 24 on the vertical plane is larger than the cross-sectional area of ​​the mounting groove 222 on the vertical plane. This design allows the cover plate 24 to cover the opening of the mounting groove 222, preventing foreign objects from entering the mounting groove 222.

[0041] Furthermore, in this embodiment, multiple partitions 14 are located at the connection points between the four spaces: the feeding chamber 10, the spraying chamber 11, the drying chamber 12, and the discharging chamber 13. The partitions 14 mainly serve to separate and divide the space, while the through-slots 140 facilitate the passage of the sheet material. Furthermore, in this embodiment, the feeding pipe 16 can be connected to a container holding paint via a flexible hose, and paint can be transported into the feeding pipe 16 via a pump, thereby providing a stable supply of paint for the spraying of the nozzle 17.

[0042] It should be added that, in this embodiment, the air duct 21 is fixedly connected to the box body 22 and the connecting pipe 201 by bolts. The bolt fixing method has the advantage of reliable connection, ensuring the stability of the connection between the air duct 21 and the box body 22 and the connecting pipe 201.

[0043] In addition, in this embodiment, the electric rollers 15 located on the upper and lower sides rotate relative to each other. That is, when the upper electric roller 15 rotates clockwise, the lower electric roller 15 rotates counterclockwise. This design allows the board to move horizontally under the rotation of the electric rollers 15 on the upper and lower sides.

[0044] It is worth noting that the hot air blower 23 involved in this embodiment is a conventional technology and will not be described in detail here.

[0045] In practical use, the user first turns on the power supply of the drive structure of the electric roller 15, and the electric roller 15 starts to work. Multiple electric rollers 15 rotate synchronously, and the rotation of the electric roller 15 drives the board to move horizontally. When the board moves into the spraying chamber 11, the paint enters through the feed pipe 16 and is sprayed onto the upper and lower surfaces of the board through multiple nozzles 17. With the horizontal movement of the board, the upper and lower surfaces of the board are evenly sprayed. When the sprayed board moves into the drying chamber 12, the user turns on the power supply of the hot air blower 23, and the hot air blows into the mounting groove 222. The hot air is filtered when it passes through multiple dust filters 27. The filtered hot air enters the upper and lower housings 20 through the air pipes 21 on both sides. Then the hot air is blown out from the exhaust duct 200 and finally blown onto the surface of the board, thereby drying the paint on the surface of the board. With the horizontal movement of the board, the surface of the board can be evenly dried.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
