Description

A powder spray booth with an automatic cleaning device

technical field

The invention relates to a powder spraying room with an automatic cleaning device.

Background technique

The side wall of the existing semi-open powder spraying room is generally in the form of a disposable film or a PU belt; the side wall in the form of a disposable film does not need to be cleaned when changing colors, but only needs to be replaced with a new film. The film consumption of the powder spraying room with the type structure is large, and the polluted film will cause damage to the environment, and the use cost is high; the side wall in the form of a PU belt has the following defects due to structural reasons, the belt is easy to run off, the belt life is short, and the later period The maintenance cost is high, and the powder on the belt surface cannot be cleaned up when the color is changed.

Contents of the invention

In order to overcome the deficiencies of the prior art, the invention provides a powder spraying booth with an automatic cleaning device.

The technical solution adopted by the present invention to solve its technical problems is:

A powder spraying room with an automatic cleaning device, comprising a powder spraying room body, the powder spraying room body including a bottom plate assembly, a top plate assembly, a number of side plate assemblies and an exhaust device, the bottom plate assembly, a top plate assembly and a number of side plate assemblies Enclosed into a closed powder spraying space or a semi-open powder spraying space with side openings, the powder spraying room body is equipped with a cleaning device, and the cleaning device is arranged on the top plate assembly, and the top plate assembly is set on the spraying spray chamber through a suspension device. Inside the powder chamber body, the top plate assembly is driven by the lifting device to move vertically and the side plate assembly is cleaned by the cleaning device.

The exhaust device includes a side exhaust pipe arranged at the joint of the two side plate components and a bottom exhaust pipe arranged at the bottom joint of the powder spraying chamber body.

The top plate assembly is provided with a suction pipe cleaning arm extending into the side suction pipe, and the suction pipe cleaning arm is equipped with a cleaning device for cleaning the side suction pipe wall.

The cleaning device is an air blowing nozzle, a wiping cloth wheel, a hair brush, a cloth brush or a scraper, or any combination of these cleaning devices.

Side baffles and front baffles are respectively arranged on the bottom plate of the powder spraying chamber body.

The beneficial effects of the present invention are: a powder spraying room with an automatic cleaning device, comprising a powder spraying room body, the powder spraying room body including a bottom plate assembly, a top plate assembly, several side plate assemblies and an exhaust device, the bottom plate assembly, The top plate assembly and several side plate assemblies enclose a closed powder spraying space or an open powder spraying space with side openings. The powder spraying room body is equipped with a cleaning device, and the cleaning device is arranged on the top plate assembly. The top plate assembly The suspension device is installed in the powder spraying room body, and the lifting device drives the top plate assembly to move vertically. When the powder spraying is completed and needs to be cleaned, the lifting device drives the top plate assembly to descend, and at the same time starts the cleaning device to clean the side plate assembly. As the top plate assembly continues to descend, the area of the air outlet in the powder spraying chamber will gradually shrink, and the air flow rate in the powder spraying room will increase, which makes the cleaning of the side plates more thorough and clean, and can be cleaned automatically, which is convenient and fast. At the same time, the top plate When descending to the lower position, it is convenient to manually clean the top plate at a lower position.

detailed description

Referring to Fig. 1 to Fig. 3, Fig. 1 to Fig. 3 is a structural schematic diagram of a specific embodiment of the present invention, as shown in the figure, a kind of powder spraying room with automatic cleaning device, comprises powder spraying room body, described powder spraying room The body includes a bottom plate assembly 1, a top plate assembly 2, a number of side plate assemblies 3 and an exhaust device. The bottom plate assembly 1, the top plate assembly 2 and a number of side plate assemblies 3 enclose an open powder spraying space with side openings. The powder spraying The chamber body is equipped with a cleaning device, the cleaning device is set on the top plate assembly 2, the top plate assembly 2 is set in the powder spraying chamber body through the suspension device, and the top plate assembly 2 is driven by the lifting device 4 to move vertically and pass through the cleaning device Clean the side plate assembly 3. When the powder spraying chamber needs to be cleaned, the lifting device 4 drives the top plate assembly 2 down, and at the same time starts the cleaning device, and during the continuous decline of the top plate assembly, the area of the air outlet in the powder spraying chamber gradually shrinks. The air flow rate between the top plate and the bottom plate will be increased, which makes the cleaning of the side plate more thorough and clean, and the cleaning can be completed automatically, which is convenient and fast. .

Preferably, as shown in the figure, the exhaust device includes a side exhaust pipe 51 arranged at the seam of the two side plate assemblies 3 and a bottom air pipe 52 arranged at the bottom seam of the powder spraying chamber body, so The top plate assembly 2 is provided with a suction pipe cleaning arm 21 extending into the side suction pipe 51, and the suction pipe cleaning arm 21 is equipped with a cleaning device for cleaning the side suction pipe 51 pipe wall, so that the present invention can When cleaning the powder spraying chamber, the side exhaust duct 51 can also be cleaned. Of course, the cleaning device for the side exhaust duct can also be installed separately, or instead of automatic cleaning, it can be replaced by manual cleaning.

In the present invention, the cleaning device can be an air blowing nozzle, a wiping cloth wheel, a hair brush, a cloth brush or a scraper, or any combination of these cleaning devices. As shown in the figure, in this embodiment, the air blowing nozzle 6 is preferably used as the cleaning device, which can be connected with the air compressor in the powder spraying system to achieve the purpose of blowing off the dust on the side plate assembly 3 .

The present invention can be used in closed powder spraying booths or open powder spraying booths with side openings. Figures 1 to 5 are examples of applications in semi-open powder spraying booths with side openings. During specific implementation, it can also be It is used for the combination of a fully enclosed powder chamber or two semi-open powder chambers, which will not be described in detail here; as shown in Figures 1 to 3, when the present invention is used in an open powder chamber, the spray gun 9 passes through The lifting system is set on the side of the powder spraying room, and the workpiece 90 passes between the powder spraying room and the spray gun 9. When the powder spraying is completed and needs to be cleaned, the lifting device 4 drives the top plate assembly 2 down, and at the same time starts the cleaning device to clean the side plate assembly 3. Clean up, and when the top plate assembly 2 drops to a certain distance, as shown in Figure 3, the spray gun 9 can be inserted between the top plate assembly 2 and the bottom plate assembly 1, and when the spray gun is cleaned, the powder will not float to the outside of the powder spraying chamber. At the same time, the cleaning of the spray gun shell can also be carried out in this strong draft area, which is convenient to improve the cleaning efficiency.

The preferred implementation of the present invention has been described in detail above. Of course, the present invention can also adopt forms different from the above-mentioned embodiments. As shown in FIGS. 4 and 5 in the present invention, an inclined roof assembly 2 can be used , so that when the top plate assembly 2 descends, a cone-shaped exhaust space as shown in Figure 5 is formed to improve the efficiency of cleaning; therefore, those skilled in the art can make equivalent transformations or corresponding changes without violating the spirit of the present invention. All should belong to the protection scope of the present invention.
