This equipment typically consists of a spray gun, powder supply system, control system, and drying and curing system, enabling automated and intelligent spraying operations.

[0003] The patent document with application number 202023299285.3 discloses an automatic electrostatic spraying equipment, including a powder spraying chamber and a hanger tooling located inside the powder spraying chamber. The hanger tooling includes two long round tubes, two rectangular square tubes and a ball screw.

[0004] However, during the electrostatic spraying process, some powder particles may not be effectively adsorbed on the surface of the aluminum veneer, but instead scattered in the air or attached to the equipment, resulting in reduced powder utilization. This not only increases production costs, but long-term accumulation may also increase the difficulty of cleaning for workers. Utility Model Content

[0005] The utility model discloses an automatic electrostatic spraying device for aluminum veneer, which aims to solve the technical problem that during the electrostatic spraying process, some powder particles may not be effectively adsorbed on the surface of the aluminum veneer, but are scattered in the air or attached to the equipment, resulting in reduced powder utilization, which not only increases production costs but also may increase the difficulty of cleaning for workers due to long-term accumulation.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An automatic electrostatic spraying device for aluminum veneer, comprising an installation box, two spraying machine bodies are arranged inside the installation box, and further comprising:

[0008] Clamping mechanism: located inside the installation box;

[0009] Cleaning mechanism: located on both sides of the clamping mechanism, the cleaning mechanism includes four baffles and two clamps, one side outer wall of the two clamps is provided with a mounting opening, and the outer wall of one side of the clamp is provided with a limiting groove, the limiting groove is communicated with the mounting opening, the bottom inner wall of the limiting groove is connected to the second threaded rod through a bearing, one end of the second threaded rod passes through the top outer wall of the clamp, and the circumferential outer wall of the second threaded rod is connected to the connecting frame through a thread, and scrapers are provided at both ends of the connecting frame, and the two adjacent baffles are respectively located on the outer walls on both sides of the clamp.

[0012] In this solution, when in use, the aluminum veneer is placed in the clamping mechanism, and the two sides of the aluminum veneer are clamped and limited, so that the two sides of the aluminum veneer that need to be sprayed are aligned with the spraying mechanism, and then the spraying mechanism sprays both sides of the aluminum veneer at the same time. After spraying is completed, the operator can manually or add a motor to drive the second threaded rod to rotate, so that the connecting frame drives the two scrapers to move up and down on the circumferential surface of the second threaded rod under the limit of the limit groove, and scrapes off the powder particles adhered to the baffle and the surface of the spraying mechanism. The scraped powder particles will fall into the collection mechanism and be collected and processed by the operator. This device can realize rapid spraying of the aluminum veneer surface, improve powder utilization, reduce production costs, avoid powder scattering in the external air, thereby affecting the health of workers and polluting the air, and reduce the difficulty of workers in cleaning scattered powder.

[0014] When in use, first place the aluminum veneer between the two clamping plates, and place the bottom of the aluminum veneer on the top outer wall of the limit plate, then start the motor, and the output shaft of the motor drives the first threaded rod to rotate. Since the outer wall of the first threaded rod has two threads in opposite directions, when the first threaded rod rotates, the two sliders and the two clamping plates will move away from or approach each other under the limit of the connecting groove. When the two clamping plates approach each other, the aluminum veneer is clamped and limited.

[0015] In a preferred solution, the spraying mechanism includes two fixed plates and two electric telescopic rods, and the inner walls of the opposite sides of the fixed plates are provided with mounting grooves and slide grooves.

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0028] The utility model discloses an automatic electrostatic spraying device for aluminum veneer, which is mainly used in scenarios where, during the electrostatic spraying process, some powder particles may not be effectively adsorbed on the surface of the aluminum veneer, but are scattered in the air or attached to the equipment, resulting in reduced powder utilization, which not only increases production costs but may also increase the difficulty of cleaning for workers due to long-term accumulation.

[0029] Reference Figure 1 and Figure 3 , an automatic electrostatic spraying device for aluminum veneer, including an installation box 1, two sprayer bodies 6 are provided inside the installation box 1, and also includes:

[0030] Clamping mechanism: located inside the installation box 1;

[0031] Cleaning mechanism: Located on both sides of the clamping mechanism, the cleaning mechanism includes four baffles 9 and two clamping plates 8. One side outer wall of the two clamping plates 8 is provided with a mounting opening 16, and one side outer wall of the clamping plate 8 is provided with a limiting groove, which is communicated with the mounting opening 16. The bottom inner wall of the limiting groove is connected to a second threaded rod 20 through a bearing. One end of the second threaded rod 20 passes through the top outer wall of the clamping plate 8. The circumferential outer wall of the second threaded rod 20 is connected to a connecting frame 14 through a thread. Both ends of the connecting frame 14 are provided with a scraper 17. The two adjacent baffles 9 are respectively located on the outer walls of the two sides of the clamping plate 8;

[0032] Spraying mechanism: located on both sides of the cleaning mechanism;

[0033] Collection mechanism: located below the cleaning mechanism.

[0034] It should be noted that the installation box 1 is a closed space during use, thereby preventing the spray powder particles from being scattered in the air. The figure shows a specific display of the interior of the installation box 1 after it is opened, and the cover on the top of the installation box 1 is not drawn in the figure.

[0035] Among them, the baffle 9 is located on one side of the splint 8 near one side, and one side of the connecting frame 14 is slidably connected to the inner wall of the limiting groove. It should be noted that the mounting port 16 is located on one side of the splint 8 near the center position, and the baffle 9 is designed to be located on one side of the splint 8 near one side. This setting prevents the baffle 9 from blocking the mounting port 16, thereby avoiding affecting the up and down movement of the scraper 17. One side of the connecting frame 14 slides in the limiting groove, thereby limiting the connecting frame 14 and preventing the connecting frame 14 from rotating with the rotation of the second threaded rod 20.

[0036] Specifically, when in use, the aluminum veneer is placed in the clamping mechanism, and the two sides of the aluminum veneer are clamped and limited, so that the two sides of the aluminum veneer that need to be sprayed are aligned with the spraying mechanism, and then the spraying mechanism sprays the two sides of the aluminum veneer at the same time. After spraying is completed, the operator can manually or add an electric motor to drive the second threaded rod 20 to rotate, so that the connecting frame 14 drives the two scrapers 17 to move up and down on the circumferential surface of the second threaded rod 20 under the limitation of the limiting groove, and scrapes off the powder particles adhered to the baffle 9 and the surface of the spraying mechanism. The scraped powder particles will fall into the collecting mechanism and be collected and processed by the operator. This device can realize rapid spraying of the surface of the aluminum veneer, improve powder utilization, reduce production costs, and avoid powder scattering in the external air, thereby affecting the health of workers and polluting the air.

The bottom outer walls of the two clamping plates 8 are provided with sliders, which are connected to the circumferential outer wall of the first threaded rod 19 by threads.

[0038] The outer circumferential wall of the first threaded rod 19 is provided with two threads in opposite directions, and the second threaded rod 20 is located inside the connecting groove.

[0039] Specifically, when in use, the aluminum veneer is first placed between the two clamps 8, and the bottom of the aluminum veneer is placed on the top outer wall of the limit plate, and then the motor 18 is started. The output shaft of the motor 18 drives the first threaded rod 19 to rotate. Since the outer wall of the first threaded rod 19 has two threads in opposite directions, when the first threaded rod 19 rotates, the two sliders and the two clamps 8 will move away from or approach each other under the limitation of the connecting groove. When the two clamps 8 approach each other, the aluminum veneer is clamped and limited.

Ten spray holes 12 are provided on one side outer wall of the nozzle head 5.

[0041] The fixing plate 3 is a concave structure, which can limit the moving direction of the support plate 15 and the nozzle 5 at the same time.

[0042] Specifically, when in use, first start the electric telescopic rod 13. The movable end of the electric telescopic rod 13 drives the support plate 15 to move up and down during the limiting process of the slide groove 4, so that the sprayer body 6 and the connecting pipe 7 move up and down synchronously. At the same time, the two sides of the nozzle 5 move up and down synchronously during the limiting process of the installation groove 11, and then the powder is transported to the nozzle 5 through the sprayer body 6 and the connecting pipe 7, and then sprayed on the surface of the aluminum veneer through the nozzle hole 12. The set electric telescopic rod 13 is convenient for adjusting the height of the sprayer body 6 and the nozzle 5 according to the actual height of the aluminum veneer, so that the powder spraying can be more uniform.

A handle is provided on one outer wall of the collection box 2. The two collection boxes 2 are respectively located on both sides of the clamping mechanism, and the clamping plate 8 is in contact with the top outer wall of the collection box 2.
