Description

Technical Field

[0001] The utility model relates to a powder spraying device, in particular to a powder spraying device for aluminum material surface processing. Background Art

[0002] The main function of aluminum powder coating is to improve the surface adsorption of the aluminum, increase the aluminum's corrosion and oxidation resistance, improve the appearance quality and mechanical properties of the aluminum, and also remove oil, dust and other debris from the aluminum surface. The aluminum powder coating process uses electrostatic adsorption to evenly cover the aluminum surface with powder coating. The powder is then baked at high temperature to melt, level and solidify the powder, forming a uniform coating.

[0003] Existing aluminum powder coating technologies can be broadly categorized as manual and machine-based. Manual powder coating requires a worker to apply powder to the aluminum surface using a handheld powder gun. Due to the instability of manual operation, this often results in uneven distribution of the powder coating. With machine-based powder coating, an automated control line moves the aluminum forward, while the machine drives the spray gun up and down, coating the surface with powder. However, this process results in far less powder being applied to the sides than the front, resulting in uneven powder distribution. This uneven powder coating significantly reduces the aluminum's appearance, resulting in inconsistent color and a rough surface, failing to meet market demand for high-quality aluminum finishes. Utility Model Content

[0004] In order to overcome the shortcoming of the existing aluminum material powder spraying technology that causes uneven distribution of powder on the aluminum material surface, the utility model provides a powder spraying device for aluminum material surface processing.

A plurality of powder spraying guns are connected to the moving part of the electric slide rail. Chain drive parts are symmetrically arranged on the front and back sides of the top of the base. A motor is provided on the right side of the top of the chain drive part, and the motor is installed on the inner wall of the shell. The motor is connected to the chain drive part in a transmission manner. Protective pads are provided on the outside of the chains of the two chain drives. Gears are rotatably connected to the protective pads at intervals. The gears are engaged with the racks, and the end of the gear away from the protective pad is connected to the moving block.

[0006] In a preferred embodiment of the present invention, a slot is provided in the middle of the top of the base, and the length of the slot side is greater than the length of the rack.

[0007] In a preferred embodiment of the present invention, a drying mechanism is further included, which includes a fan, a heating wire and a filter. An opening is provided on the right side of the top of the shell, and the fan, the heating wire and the filter are installed in the opening in sequence from bottom to top.

[0008] In a preferred embodiment of the present invention, a baffle is further included, and baffles are provided on both the front and rear sides of the shell.

[0009] In a preferred embodiment of the present invention, a lower hopper is further included. The lower hopper is provided on the left side of the shell and is located between the left ends of the two chain driving members.

[0010] In a preferred embodiment of the present invention, a plastic door curtain is further included, and a plastic door curtain is provided at intervals on the top of the shell.

[0011] Compared with existing technologies, this utility model has the following advantages: The meshing of the gear and rack drives the moving block to rotate, which in turn drives the aluminum material between the moving blocks to rotate.
