Description

Technical Field

[0001] This utility model relates to the field of metal surface spraying technology, specifically to a powder recovery device for metal surface spraying. Background Technology

[0002] Powder coating technology is widely used due to its high efficiency and environmental friendliness. This technology uses powder spraying equipment to uniformly apply powder coating to the surface of a workpiece. Under electrostatic attraction, the powder adheres tightly to the workpiece, forming a uniform powdery coating. However, in actual spraying processes, due to the complexity of the spraying environment and differences in workpiece shape and size, some powder often fails to reach the workpiece surface and instead remains scattered on the workbench or inside the workshop. This uncoated powder not only wastes raw materials and increases production costs but may also negatively impact the working environment and worker health.

[0003] Patent document CN222766576U discloses a powder recovery device for metal surface spraying, including: a base, on which a foldable bracket is provided; the application can recover scattered powder through a lifting component, a crossbeam, an adsorption end and a collection end, reducing the waste of raw materials and lowering production costs.

[0004] However, this application lacks active cleaning of the filter structure. Since the filter screen is the key to the airflow channel, powder continuously accumulates on the filter screen surface, forming a powder cake. This causes a sharp increase in airflow resistance, which in turn increases system pressure loss. This directly leads to a decrease in air volume and air velocity, and the suction force of the adsorption hood will be significantly weakened. It will be unable to effectively capture distant drifting powder, resulting in a decrease in recovery rate and workshop pollution. This seriously affects the recovery effect and cannot meet the usage requirements. Therefore, a powder recovery device for metal surface spraying is proposed to solve the problems mentioned above.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 5 This embodiment of a powder recovery device for metal surface spraying includes a base 1 and a guide assembly disposed above the base 1. Specifically, the guide assembly includes a guide rail 2 fixed to the upper surface of the base 1, an electric lifting platform 3 slidably mounted on the inner side of the guide rail 2, a guide frame 4 fixed on the upper surface of the electric lifting platform 3, and a slide table 5 slidably mounted inside the guide frame 4. A dust collection device is disposed above the base 1, which consists of a dust collection component 6, a filter box 7, a dust collection hood 8, and a drive component 10. The dust collection hood 8 is connected and fixed to the slide table 5 by bolts.

[0020] It should be noted that the guide rail 2 and the guide frame 4 are arranged in the X and Y axis directions. An electric telescopic rod 41 is installed on the outer wall of the guide frame 4, and the output end of the electric telescopic rod 41 is connected and fixed to the outer wall of the slide table 5. The guide rail 2, electric lifting platform 3, guide frame 4 and slide table 5 in the guide assembly form a moving system in the X and Y axis directions, which can flexibly adjust the position of the dust collection hood 8 so that it can be accurately aligned with different areas of the metal surface spraying process, adapting to various processing scenarios and workpiece shapes. A hydraulic support device can also be installed on the bottom side of the base 1 to ensure the stability of the cover device. The hydraulic support device is a conventional technology known to the public in the prior art, so its specific structural composition and working principle will not be described in detail in this article.

[0021] To achieve powder recovery, the dust collection assembly 6 includes a housing 61 fixed to the upper surface of the base 1. A fan impeller 62 is installed on the top side of the housing 61. The bottom output shaft of the drive motor 101 is connected and fixed to the outer wall of the fan impeller 62. A conveying pipe is installed between the housing 61 and the filter box 7. In this embodiment, the filter box 7 includes a filter box 7 fixed to the upper surface of the base 1. A filter plate 71 is detachably installed inside the filter box 7. The filter plate 71 is bolted on, which greatly facilitates the maintenance and upkeep of the equipment. When too much powder accumulates on the filter plate 71, affecting the dust collection effect, the operator can easily remove the filter plate 71 for cleaning or replacement without the need for a complex disassembly of the entire filter box 7. A connecting pipe 81 is installed between the dust collection hood 8 and the filter box 7. Specifically, the connecting pipe 81 can be a flexible hose, and the dust collection assembly 6 communicates with the filter box 7. A sealing cap is bolted on the top side of the filter box 7.

[0022] To improve dust collection efficiency, the filter box 7 is equipped with a striking assembly 9 and a piston assembly 11 connected to the drive assembly 10. Specifically, the striking assembly 9 includes a striking plate 91 disposed inside the filter box 7, with an abutment block 92 fixed to one side of the striking plate 91. There are two striking plates 91, arranged vertically. The abutment block 92 has an air outlet 95 that works in conjunction with the piston assembly 11. While the striking plate 91 strikes the filter plate 71, causing powder to fall off, the airflow generated by the piston assembly 11 blows towards the filter plate 71 through the air outlet, further removing residual powder, improving the cleanliness of the filter plate 71, and enhancing the dust collection effect.

[0023] It is worth mentioning that the two vertically distributed tapping plates 91 can tap the filter plates 71 at different heights inside the filter box 7. During the metal surface spraying process, powder will adhere to different positions of the filter plates 71. The two tapping plates 91 can more comprehensively cover the filter plates 71, so that the powder adhering to the filter plates 71 can be more effectively removed, preventing the filter plates 71 from clogging, thereby ensuring smooth airflow inside the filter box 7 and maintaining good dust collection effect.

[0024] To ensure stable movement of the striking plate 91, a guide component is provided inside the filter box 7 to guide the striking plate 91. The guide component includes a guide rod 93 fixed to the inner wall of the filter box 7 and a buffer spring 94. The guide rod 93 penetrates the interior of the striking plate 91, and the other side of the buffer spring 94 is fixed to the outer wall of the striking plate 91. The guide rod 93 penetrates the interior of the striking plate 91, providing precise guidance for the movement of the striking plate 91. During the reciprocating motion of the striking plate 91, the guide rod 93 ensures that the striking plate 91 moves along a predetermined straight trajectory, preventing the striking plate 91 from deviating or shaking, ensuring that the striking action is accurately applied to the filter plate 71, and improving cleaning efficiency.

[0025] To further improve the cleaning effect, the piston assembly 11 includes a pressure cylinder 111 fixed to the outer wall of the filter box 7. A piston block 112 extending outwards is slidably disposed inside the pressure cylinder 111. An air supply pipe 113 is installed on the outer wall of the pressure cylinder 111, and the other end of the air supply pipe 113 is fixedly connected to the top abutment block 92. A connecting plate 114 is installed at one end of the piston block 112 extending out of the pressure cylinder 111, and the other side of the connecting plate 114 is fixed to the outer surface of the reciprocating shaft 104. It should be noted that both the pressure cylinder 111 and the piston block 112 are equipped with check valves, and the air supply pipe 113 is connected to the check valve on the pressure cylinder 111; the piston block 112 has a T-shaped outer shape.

[0026] In this embodiment, the drive assembly 10 includes a drive motor 101, which is a dual-axis motor. The top output shaft of the drive motor 101 is fixed with a turntable 102. The filter box 7 is equipped with a reciprocating shaft 104, one end of which is fixed to the striking plate 91, and the other end of which is hinged to the turntable 102 with a connecting rod 103. Specifically, a motor frame is installed on the top side of the housing 61, and the drive motor 101 is fixedly installed on the motor frame.

[0027] The working principle of the above embodiments is as follows: Start the drive motor 101 to drive the fan impeller 62 to rotate, generating negative pressure in the housing 61. Through the conveying pipe, a negative pressure environment is formed in the filter box 7. Outside air carries the powder generated by the metal surface spraying process and enters the filter box 7 through the dust collection hood 8 and the connecting pipe 81. When the powder passes through the filter plate 71 in the filter box 7, it is intercepted by the filter plate 71, and clean air is discharged. The top output shaft of the drive motor 101 drives the turntable 102 to rotate. The turntable 102 drives the reciprocating shaft 104 to reciprocate through the connecting rod 103. Since one end of the reciprocating shaft 104 is fixed to the striking plate 91, the striking plate 91 also reciprocates. During the reciprocating motion of the striking plate 91, it continuously strikes the filter plate 71, causing the powder adhering to the filter plate 71 to fall off and preventing the filter plate 71 from clogging. In addition, when the reciprocating shaft 104 reciprocates, it drives the connecting plate 114 to move. The connecting plate 114 drives the piston block 112 to slide inside the pressure cylinder 111. When the piston block 112 slides into the pressure cylinder 111, the gas in the pressure cylinder 111 is blown onto the filter plate 71 through the air outlet 95 via the air supply pipe 113, further assisting in cleaning the powder on the filter plate 71.

Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
