Description

Technical Field

[0001] The utility model relates to the technical field of door painting, in particular to a door painting and spraying device. Background Technique

[0002] Spraying is to disperse into uniform and fine droplets through a spray gun or a disc atomizer with the help of pressure or centrifugal force and apply them to the surface of the object to be painted. It can be divided into air spraying, airless spraying, electrostatic spraying and various derivative methods of the above basic spraying forms.

[0003] During the production and processing of the door, it is necessary to spray the surface to form a protective film on the surface of the door to achieve the effects of preventing oxidation and corrosion. In the prior art, during the spraying of the door, the door will be clamped and fixed by a clamping mechanism and then sprayed. However, during the spraying process, in addition to adhering to the surface of the door, the atomized paint sprayed by the spraying machine is also likely to adhere to the surface of the clamping mechanism. With the continuous spraying of the spraying machine, a thick layer of paint will adhere to the surface of the clamping mechanism, which is difficult to clean and is also likely to affect the clamping effect of the clamping mechanism on the door.

[0004] Therefore, those skilled in the art have proposed a door painting and spraying device to solve the problems raised in the above background. Content of the Utility Model

[0018] The technical solutions of this patent will be further described in detail below in conjunction with the specific embodiments.

[0019] Please refer to Figures 1 - 3, a door painting spraying device, including a spraying box 1; clamping components are arranged on both sides of the spraying box 1 for clamping the door. A liquid storage tank 8 is arranged on the top of the spraying box 1 for storing paint. The liquid storage tank 8 is connected with a conveying pipe 9, and the conveying pipe 9 is successively connected with a pump body 11 and a spray head 10. The pump body 11 is installed on the outer wall of the liquid storage tank 8. A moving component is arranged on the top wall of the spraying box 1 for adjusting the spraying position of the spray head 10. Partition components are arranged on both sides of the spraying box 1 for partitioning the spraying area and the clamping components.

[0020] Put the door into the spraying box 1, and clamp and fix the door through the clamping components. By starting the pump body 11, the conveying pipe 9 can extract the paint in the liquid storage tank 8 and transport it to the spray head 10 for spraying. The spray head 10 sprays the paint onto the surface of the door. When the clamping components clamp the door, a partition component is arranged between the clamping components and the door for partitioning the spraying area and the clamping components, so as to avoid the problem that a thick layer of paint will adhere to the clamping components during spraying, resulting in difficult cleaning. And the partition component can be replaced to avoid affecting the spraying of subsequent doors.

[0021] In one case of this embodiment, the clamping components include hydraulic rods 2 installed on both sides of the spraying box 1. Clamping plates 3 are installed on the hydraulic rods 2. Place the door between the two clamping plates 3 and start the hydraulic rods 2 to complete the clamping of the door by the two clamping plates 3. The specific shape and structure of the clamping plate 3 are not limited. Preferably, the clamping plate 3 can be set as a U shape to facilitate clamping the door.

[0022] In one case of this embodiment, the partition components include brackets 15 installed at both ends of the spraying box 1 and symmetrically distributed. A film roller 16 is rotatably arranged on the brackets 15, and a film belt 17 is wound on the film roller 16. A second motor 18 connected to the film roller 16 is installed on the brackets 15. Symmetrically distributed guide rollers 19 that are in contact with the film belt 17 are rotatably arranged at both ends in the spraying box 1. During use, pass the film belt 17 through the guide rollers 19 to make it adhere to the surface of the clamping plate 3. Thus, when the clamping plate 3 clamps the door, the clamping plate 3 can be prevented from being exposed in the spraying area. By arranging the film belt 17, the paint sprayed by the spray head 10 can adhere to the film belt 17, avoiding the paint directly adhering to the surface of the clamping plate 3. And when the paint adhering to the film belt 17 is too thick to affect the clamping of the clamping plate 3, the second motor 18 can be started to drive the film roller 16 to rotate, so that the film roller 16 at the upper end of the spraying box 1 releases the film belt 17, while the film roller 16 below retracts the film belt 17, causing the film belt 17 to move downward. Thus, the film belt 17 can be replaced, saving the time for cleaning the clamping plate 3, and the use effect is better.

[0023] In a case of this embodiment, the moving member includes a fixing frame 4 installed on the top of the spraying box 1. A screw rod 5 is rotatably arranged in the fixing frame 4. A first motor 7 connected to the screw rod 5 is installed in the fixing frame 4. A moving frame 6 that is threadedly connected to the screw rod 5 and slidably connected to the fixing frame 4 is connected to the spray head 10. During use, by starting the first motor 7, the screw rod 5 is driven to rotate, so that the moving frame 6 moves horizontally, thereby changing the spraying position of the spray head 10.

[0024] In a case of this embodiment, a collection box 12 is provided at the bottom of the spraying box 1 for collecting the residual paint during the spraying process.

[0025] In a case of this embodiment, support frames 13 are provided on both sides inside the collection box 12. Scrapers 14 that contact the film belt 17 are provided on the support frames 13. When the film belt 17 is replaced, the film belt 17 moves downward. During this process, the scrapers 14 clean the paint on the surface of the film belt 17, and the use effect is better.

[0026] The working principle of the present utility model is as follows: The car door is placed in the spraying box 1 and clamped and fixed by the clamping member. By starting the pump body 11, the conveying pipe 9 can extract the paint from the liquid storage tank 8 and convey it to the spray head 10 for spraying. The spray head 10 sprays the paint onto the surface of the car door. And when the clamping member clamps the car door, a separating member is provided between the clamping member and the car door for separating the spraying area and the clamping member, thereby avoiding the problem that a thick layer of paint adheres to the clamping member during spraying, making it difficult to clean. And the separating member can be replaced to avoid affecting the spraying of subsequent car doors. When the film belt 17 is replaced, the film belt 17 moves downward. During this process, the scrapers 14 clean the paint on the surface of the film belt 17, and the use effect is better.

[0027] The present utility model clamps and fixes the car door through the provided clamping member, and then drives the spray head 10 to move horizontally through the moving member, thereby spraying the car door. And during the spraying process, the spraying area is separated from the clamping member through the separating member, thereby avoiding the problem that a thick layer of paint adheres to the clamping member during spraying, making it difficult to clean.
