AI Technical Summary

Technical Problem

Existing powder coating equipment uses hooks on a heavy-duty suspended conveyor chain to hang the frame to be powder coated. This causes the frame to sway when moving, making it impossible for the spray gun to stay aligned and resulting in uneven powder coating.

Method used

The frame is held in place by a sliding clamp. The sliding clamp moves synchronously through a threaded rod. The rotating disk, which meshes with the toothed ring and rack, drives the fixed rod and the nozzle to move, ensuring that the nozzle and the frame move synchronously. The amount of material sprayed is controlled by an adjustment plate. The collection shell collects the unattached powder, reducing air pollution.

Benefits of technology

It achieves more uniform powder coating, reduces powder floating in the air, improves the powder coating effect, and protects the health of workers.

[0002] The plastic spraying equipment is a device for spraying plastic on the surface of an object, so that the powder adheres to the surface of the object, thereby preventing the surface of the object from oxidizing and prolonging the service life of the object. There are two ways for spraying plastic on the object, namely, electrostatic spraying and self-drying spraying. The electrostatic spraying is a mainstream spraying method for spraying plastic on the basketball stand body. In this method, the powder is adsorbed on the surface of the basketball stand body by electrostatic field force, and then the powder on the stand body is reinforced by high-temperature baking.

When the spray head 9 rotates to the upper turning position, the adjusting plate 24 unblocks the spray head 9, so that the spray head 9 is opened to the maximum flow capacity.

The communication position of the collection shell 13 and the collection pipe 15 is located at the lower part of the collection shell 13, so as to facilitate the suction of the powder falling on the lower part of the collection shell 13 into the collection pipe 15. A filter screen is arranged at the communication position of the air inlet of the fan 16 and the collection barrel 14, thereby reducing the probability of the powder re-entering the air from the fan 16.

[0037] In the process of spraying, the fan 16 is started to suck the air out of the collection barrel 14, so that a negative pressure is formed in the collection barrel 14. Then the air enters the collection shell 13 through the collection pipe 15 and enters the collection barrel 14, and then the floating powder is sucked into the collection shell 13, thereby reducing the pollution of the powder to the air and protecting the health of the workers.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit the protection scope of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present application.
