Technical Field
[0001] This utility model belongs to the technical field of composite spraying equipment, specifically relating to a powder supply device for composite spraying equipment. Background Technology
[0002] Composite spraying equipment is a device that integrates multiple spraying technologies, capable of performing different types of spraying processes simultaneously or sequentially, and suitable for the application of various coating materials. By integrating different spraying methods (such as electrostatic spraying, air spraying, high-pressure airless spraying, etc.), it meets the surface treatment needs of complex workpieces, improving coating quality and production efficiency.
[0003] Chinese Patent Application No. 2018217271273 discloses a powder supply box suitable for powder coatings. The box has a lid on top, with a feed inlet on one side edge of the lid, equipped with a dust cover. A dust outlet is distributed through the other side of the lid. Several powder pump ports are distributed through the front and rear sides of the lid, with suction pipes extending into the box. Cylinders are located on the bottom of the box, connected to air inlets penetrating the box, and have several air caps on their surfaces. This invention features a simple structure and a novel, reasonable design. The arrangement of cylinders and evenly distributed air caps at the bottom of the powder supply box creates a more uniform fluidized bed for the powder coating. The air pumps, combined with flared suction pipes, ensure more even powder coating absorption. The large-volume powder supply box and the multiple powder pump openings on the lid allow for simultaneous spraying by multiple users, improving equipment utilization and significantly increasing work efficiency.
[0004] The aforementioned patent does not have a dispersing function and cannot disperse the powder added to the box. When the powder added to the box clumps together, it affects subsequent use. At the same time, the original device cannot dry the powder added to the box, and when the powder is too moist, it affects the subsequent conveying effect. Utility Model Content

[0024] The dispersing assembly 2 includes a feed pipe 21, a cover plate 22, a motor 23, a main rod 24, a secondary rod 25, dispersing rods 26, a gear 1 27, and a gear 2 28. The feed pipe 21 is installed on the upper end of the cover 5 away from the powder pump 6. The upper end of the feed pipe 21 is rotatably connected to the cover plate 22. The motor 23 is installed on one side of the front end of the feed pipe 21. The output end of the motor 23 is provided with the main rod 24. The secondary rod 25 is provided on one side of the main rod 24. Several dispersing rods 26 are fixed on both the secondary rod 25 and the main rod 24. The rear ends of the main rod 24 and the secondary rod 25 are respectively fixed with gear 1 27 and gear 2 28.
[0025] Specifically, the cover plate 22 and the feed pipe 21 are connected by a hinge. One end of the cover plate 22 is fixed with a lug, and the upper end of the feed pipe 21 is glued with a rubber pad.
[0026] By adopting the above technical solution, the cover plate 22 can rotate on the feed pipe 21, and the lug is provided to facilitate the movement of the cover plate 22. The rubber pad is provided at the upper end of the feed pipe 21 so that the sealing between the cover plate 22 and the feed pipe 21 is better after the cover plate 22 is closed.
[0027] Specifically, the dispersing rods 26 on the main rod 24 and the auxiliary rod 25 are staggered, and one end of the dispersing rods 26 on the main rod 24 and the auxiliary rod 25 is staggered from the inner wall of the feed pipe 21.
[0028] By adopting the above technical solution, there will be no collision between the main rod 24 and the dispersing rod 26 on the auxiliary rod 25, and the rotation of the main rod 24 and the dispersing rod 26 on the auxiliary rod 25 will not scrape against the inner wall of the feed pipe 21.
[0029] In this embodiment, when using the powder supply device for the composite spraying equipment, the device is installed in a suitable position, and compressed gas is introduced into the air inlet 4. The compressed gas is sprayed out through the air cap 7, and the powder forms a fluidized bed under air pressure. The powder pump 6 sucks and transports the powder in the box 1 through the powder suction pipe 8. By setting the dispersing component 2, the motor 23 is turned on to drive the main rod 24 to rotate.

After the powder is added to the feed pipe 21, the cover plate 22 is rotated to close and seal the upper end of the feed pipe 21. When the powder enters the feed pipe 21, the main rod 24 and the auxiliary rod 25 rotate in opposite directions and disperse the clumped powder through several dispersing rods 26. The dispersed powder falls into the box 1. By setting the dispersing component 2, the clumped powder can be dispersed to avoid the clumped powder affecting the subsequent conveying effect. Example
[0030] The difference between this embodiment and embodiment 1 is that a drying component 3 is provided at the lower end of the box cover 5, corresponding to the position of the feed pipe 21;
[0031] The drying assembly 3 includes a horizontal plate 31, a hot air blower 32, an air supply pipe 34, a fixed pipe 35, and an air outlet 37. The horizontal plate 31 is fixed at one end of the housing 1 at a position corresponding to the feed pipe 21. The hot air blower 32 is installed on the upper end of the horizontal plate 31. The fixed pipe 35 is provided on one side of the inside of the housing 1 at a position corresponding to the feed pipe 21. One end of the fixed pipe 35 is provided with an air outlet 37. The fixed pipe 35 and the hot air blower 32 are connected by the air supply pipe 34.
[0032] By adopting the above technical solution, the hot air blower 32 is turned on and hot air is sent into the fixed pipe 35 through the air supply pipe 34. Hot air is blown out from the air outlet 37 at one end of the fixed pipe 35. At the same time, the hot air blown out from the air outlet 37 at one end of the fixed pipe 35 can dry the falling powder. After that, the powder falls into the box 1. By setting the drying component 3, the powder added to the box 1 can be dried to avoid the powder being too moist and not conducive to transportation.
[0033] Specifically, the drying assembly 3 also includes a feeding seat 33 and a connecting post 36. The feeding seat 33 is fixed at the lower end of the box cover 5 at the position corresponding to the feeding pipe 21, and the fixed pipe 35 is connected to the feeding seat 33 through the connecting post 36.
[0034] By adopting the above technical solution, the feed seat 33 can guide the powder, and the connecting column 36 makes the connection between the fixing tube 35 and the feed seat 33 more secure.
[0035] Specifically, the width of the fixed tube 35 is greater than the width of the feed inlet of the feed seat 33, and the connection between the connecting column 36 and the fixed tube 35, as well as between the connecting column 36 and the feed seat 33, are all welded by pressure welding.
[0036] By adopting the above technical solution, the width of the fixed tube 35 is greater than the width of the material outlet of the feed seat 33, which increases the air blowing range of the air outlet 37. The pressure welding makes the connection between the connecting column 36 and the fixed tube 35, as well as between the connecting column 36 and the feed seat 33, more secure.
[0037] In this embodiment, by setting up the drying component 3, the hot air blower 32 is turned on and hot air is sent into the fixed pipe 35 through the air supply pipe 34. Hot air is blown out from the air outlet 37 at one end of the fixed pipe 35. The dispersed powder enters the feeding seat 33 and falls down. At the same time, the hot air blown out from the air outlet 37 at one end of the fixed pipe 35 can dry the falling powder. After that, the powder falls into the box 1. By setting up the drying component 3, the powder added to the box 1 can be dried to avoid the powder being too moist, which is not conducive to transportation.

The powder forms a fluidized bed under air pressure. The powder pump 6 sucks and transports the powder in the box 1 through the powder suction pipe 8. By setting the dispersing component 2, the motor 23 is turned on to drive the main rod 24 to rotate. The rotation of the main rod 24 drives the auxiliary rod 25 to rotate counterclockwise with the main rod 24 through gear 1 27 and gear 2 28. After the powder is added to the feed pipe 21, the cover plate 22 is rotated to close and seal the upper end of the feed pipe 21. When the powder enters the feed pipe 21, the main rod 24 and the auxiliary rod 25 rotate in opposite directions. Several dispersing rods 26 disperse the clumped powder, and the dispersed powder falls into the box 1. By setting the dispersing component 2, the clumped powder can be dispersed to avoid the clumped powder affecting the subsequent conveying effect. By setting the drying component 3, the hot air fan 32 is turned on to send hot air into the fixed pipe 35 through the air supply pipe 34. The hot air blows out from the air outlet 37 at one end of the fixed pipe 35. The dispersed powder falls into the feeding seat 33. At the same time, the hot air blown out from the air outlet 37 at one end of the fixed pipe 35 can dry the falling powder. After that, the powder falls into the box 1. By setting the drying component 3, the powder added to the box 1 can be dried to avoid the powder being too moist and not conducive to conveying.
