Description

Technical Field

[0001] The utility model relates to the technical field of powder spraying, in particular to a combined grading type powder spraying device. Background Art

[0002] Powder spraying is to spray powder coatings onto the surface of workpieces with powder spraying equipment (electrostatic powder spraying machine). Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece, forming a powdery coating; the powdery coating is cured by high-temperature baking and leveling, and becomes a final coating with different effects (different types of powder coatings have different effects); the spraying effect of powder spraying is superior to that of spray painting in terms of mechanical strength, adhesion, corrosion resistance, aging resistance, etc., but the cost is higher than that of spray painting.

[0003] However, when the existing powder spraying device is in use, it usually requires workers to hold the device by hand to perform powder spraying treatment on the surface of the workpiece. The operation steps are cumbersome, the workload is large, and the sprayed powder will cause harm to the workers' bodies. At the same time, when spraying coarse powder and fine powder on the surface of the workpiece, the workers need to frequently replace the equipment, and the operation is cumbersome, which has a certain impact on the processing efficiency of the workpiece. Therefore, a combined grading type powder spraying device is provided. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a combined grading type powder spraying device. By setting motor B, motor C, placing plate A, placing plate B, one-way lead screw, cylinder, support plate, electric telescopic rod, support rod A and support rod B, the utility model solves the problem that when the existing powder spraying device is in use, it is inconvenient to perform powder spraying treatment on different positions of the workpiece, and the processing efficiency of the workpiece is low.

[0005] The technical solution adopted by the present utility model to solve its technical problems is a combined grading powder spraying device, including a base and a fixing frame. On one side of the base, a placing plate A for placing workpieces is bolted. Inside the placing plate A, a motor A that drives the gear A outside the transmission rod to rotate is bolted. The gear A is externally meshed with a gear B that drives a bidirectional lead screw to rotate. The transmission sleeves A and B are threadedly connected to the outside of the bidirectional lead screw. A driving plate A is welded to the outside of the transmission sleeve A, and a limiting block A for limiting the workpiece is welded to the outside of the driving plate A. A driving plate B is welded to the outside of the transmission sleeve B, and a limiting block B for limiting the workpiece is welded to the outside of the driving plate B. Inside the fixing frame, a bearing block that rotates the fixing plate is screwed and fixed. Inside the fixing plate, an electric push rod that drives the placing plate B to move is screwed and fixed. Inside the fixing frame, a cylinder that drives the support plate to move is bolted. On the outside of the support plate, an electric telescopic rod that drives the vertical plate to move is bolted. A connecting frame A and a connecting frame B are welded to the outside of the vertical plate, and the connecting frame A is located above the connecting frame B. Inside the connecting frame A, a motor B that drives a unidirectional lead screw to rotate is bolted. A threaded sleeve that drives the support rod A to move is threadedly connected to the outside of the unidirectional lead screw. A spray head A for powder spraying on the surface of the workpiece is screwed and fixed to the outside of the support rod A. On one side of the connecting frame B, a support rod B for fixing the spray head B is provided. A branch pipe A connected to the pump body A is screwed and fixed to one side of the spray head A. A fixing pipe A connected to the tank body A is screwed and fixed to the outside of the pump body A. A branch pipe B connected to the pump body B is screwed and fixed to the outside of the spray head B. A fixing pipe B connected to the tank body B is screwed and fixed to the outside of the pump body B. Inside the base, a motor C is bolted, and a vertical rod that drives the placing plate A to rotate is screwed and fixed to one side of the motor C.

[0006] By adopting the above technical solution, when powder spraying and processing the workpiece, first place the workpiece into the placing plate A on the base. Then, the motor A inside the placing plate A drives the gear A outside the transmission rod to rotate. The gear A drives the bidirectional lead screw on the gear B to rotate. The transmission sleeves A and B outside the bidirectional lead screw drive the driving plate A and the driving plate B to move respectively. The driving plate A drives the limiting block A to move, and the driving plate B drives the limiting block B to move, so that the limiting block A and the limiting block B clamp the workpiece. Subsequently, the electric push rod inside the fixing plate drives the placing plate B to move, so that the placing plate B moves to the outside of the workpiece. And the internal structure of the placing plate B is the same as that of the placing plate A, so that the workpiece inside the placing plate B is fixed, avoiding the workpiece from shifting during powder spraying and processing.

[0007] After the workpiece is fixed in the placement plate A and the placement plate B, the electric telescopic rod in the support plate drives the vertical plate to move, so that the spray heads A and B move to the outside of the workpiece. Then, the pump A on the tank A transports the coarse powder in the tank A to the branch pipe A through the fixed pipe A. Then, the spray head A on one side of the branch pipe A sprays the powder on the surface of the workpiece. Then, the motor B in the connecting frame A drives the one-way lead screw to rotate, and the threaded sleeve outside the one-way lead screw drives the spray head A on the support rod A to move horizontally. At the same time, the cylinder in the fixed frame drives the support plate to move, the electric telescopic rod on the support plate drives the connecting frame A on the vertical plate to move, and the support rod A on the connecting frame A drives the spray head A to move longitudinally, so that the spray head A performs powder spraying treatment on different positions of the workpiece. After the spray A sprays the coarse powder on the workpiece, the pump B outside the tank B transports the fine powder in the tank B to the branch pipe B on one side of the pump B through the fixed pipe B. Subsequently, the spray head B on one side of the branch pipe B sprays the fine powder on the surface of the workpiece, and the internal structure of the connecting frame B is the same as the internal structure of the connecting frame A, so that the spray head B on one side of the support rod B can move horizontally and longitudinally to perform fine powder spraying treatment on the position where the coarse powder of the workpiece is sprayed, thereby improving the durability of the workpiece;

[0008] When the powder spraying on one side of the workpiece is completed, the motor C in the base drives the vertical rod to rotate, the vertical rod drives the placement plate A to rotate, and the fixed plate rotates through the bearing in the fixed frame. The electric telescopic rod on one side of the fixed plate drives the placement plate B to rotate, so that the placement plate A and the placement plate B drive the workpiece to turn over, thereby facilitating powder spraying treatment on different positions of the workpiece and improving the processing efficiency of the workpiece.

[0009] Specifically, the outer side of the base is symmetrically bolted with a blower that generates suction in the base, and the inner side of the base is screwed with a collection net for collecting excess powder.

[0010] By adopting the above technical solution, when powder spraying is performed on the workpiece, the blower on the base starts to work to generate suction on the base. Subsequently, the powder outside the workpiece is sucked into the base, and the collection net in the base collects and processes the powder, thereby improving the utilization rate of the powder. And the powder collected on the collection net is cleaned regularly to prevent the collection net from being blocked.

[0011] Specifically, a sliding rod is welded inside the fixed frame, and a limiting sleeve connected to the support plate is slidably connected to the outside of the sliding rod.

[0012] By adopting the above technical solution, when the cylinder drives the support plate to move, the limiting sleeve outside the support plate slides on the outside of the sliding rod, improving the stability of the support plate moving in the fixed frame.

[0013] Specifically, the inner sizes of the transmission sleeve A and the transmission sleeve B are both in line with the outer size of the bidirectional lead screw.

[0014] By adopting the above technical solution, when the drive sleeve A and the drive sleeve B move outside the bidirectional lead screw, the inner sides of the drive sleeve A and the drive sleeve B are both in conformity with the outside of the bidirectional lead screw, improving the stability of the movement of the drive sleeve A and the drive sleeve B outside the bidirectional lead screw.

[0015] Specifically, the input ends of the blower, the motor A, the motor B, the pump body A, the pump body B, the electric push rod, the electric telescopic rod and the cylinder are all electrically connected to the output end of an external power supply.

[0016] By adopting the above technical solution, by connecting to an external power supply, the electrical equipment operates normally.
