Description

Technical Field

[0001] This utility model relates to the field of electrostatic spraying technology, and in particular to an electrostatic spraying dehumidification device. Background Technology

[0002] In metal product surface treatment processes, electrostatic spraying technology is widely used due to its advantages such as uniform coating, strong adhesion, and high paint utilization. However, traditional electrostatic spraying processes face a key technical challenge: residual moisture on the workpiece surface severely affects the spraying quality. When moisture is present on the surface of the workpiece to be sprayed, it can lead to quality defects such as bubbles, orange peel texture, and reduced adhesion, and in severe cases, even large-area peeling of the coating. However, existing electrostatic spraying dehumidification devices still suffer from problems such as inefficient dehumidification of the workpiece surface, inability to dehumidify the workpiece comprehensively, and inability to collect dripping water.

[0003] Therefore, it is essential to invent an electrostatic spraying dehumidification device. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an electrostatic spraying dehumidification device, which solves the problems of existing electrostatic spraying dehumidification devices still failing to efficiently dehumidify the workpiece surface, failing to dehumidify the workpiece from all angles, and failing to collect falling water. An electrostatic spraying dehumidification device includes a supporting base, a support seat, a screw drive structure, a drive device, a support frame, a high-pressure dehumidification component, a water collection tank, and a workpiece support seat. The support seat is fixedly installed on the surface of the supporting base, and the screw drive structure is fixedly installed on the front side of the support seat. The drive device is fixedly installed on top of the support seat and the screw drive structure. The support frame is fixedly installed on the front side of the screw drive structure, and the high-pressure dehumidification component is fixedly installed on the support frame. The water collection tank is fixedly installed on the surface of the supporting base and located directly below the high-pressure dehumidification component. The workpiece support seat is rotatably installed at the center line position of the water collection tank.

[0005] The high-pressure dehumidification assembly includes a support frame, an adjusting joint, a connecting seat, a dehumidification nozzle, and a high-pressure gas pipe. The support frame is fixedly installed on the support skeleton, and the adjusting joint is installed at both ends of the support frame. The connecting seat is installed below the adjusting joint, and the dehumidification nozzle is fixedly installed at the inner end of the connecting seat. The high-pressure gas pipe is fixedly installed at the outer end of the connecting seat.

[0006] The dehumidifying nozzle includes a connecting pipe, an angle adjustment seat, a nozzle, a limiting seat, and an air outlet. The connecting pipe is fixedly installed inside the connecting seat and connected to a high-pressure gas pipe. The angle adjustment seat is rotatably installed at one end of the connecting pipe, and the nozzle is fixedly installed on the angle adjustment seat. The limiting seat is fixedly installed at both ends of the nozzle. The air outlet is located inside the nozzle.

[0007] The internal support frame of the high-pressure dehumidification component adopts a "U"-shaped steel metal frame, and the connecting seat adopts two sets of metal seats. The connecting seat can be adjusted up and down at both ends of the support frame by adjusting the joints; one end of the high-pressure gas pipe is connected to an external high-pressure air pump, and high-pressure gas is sprayed out through the dehumidification nozzle.

[0008] Two sets of dehumidifying nozzles are used, and the air outlet direction of the dehumidifying nozzles is facing inward and tilted downward according to the adjustment of the connecting seat; the air outlet is a long strip-shaped opening, and the gas sprayed from the air outlet is fan-shaped. The width of the fan-shaped gas sprayed from the air outlet is limited by the limiting seat.

[0009] The workpiece support base is a metal disc that is driven to rotate by a motor, and an electromagnet is installed inside the workpiece support base. The workpiece support base uses the magnetic force generated by the electromagnet to attract the metal workpiece.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. This utility model's high-pressure dehumidification component, serving as a key pretreatment device before electrostatic spraying, generates a 0.6-0.8MPa directional impact airflow through two sets of adjustable-angle dehumidification nozzles, which, in conjunction with a rotating workpiece support, achieves rapid and uniform drying of the workpiece surface. This component can reduce the moisture content to 50mg / m³ within 30 seconds. 2 The U-shaped support frame and angle adjustment joint ensure full coverage of workpieces of different shapes, improving drying efficiency by more than 40% compared to traditional methods. At the same time, it forms a moisture recovery system with the water collection tank, providing ideal drying conditions for the substrate in the subsequent electrostatic spraying process.

[0012] 2. The dehumidifying nozzle of this utility model is designed to deliver high-pressure gas through a connecting pipe, and achieve precise spraying at 15-25° via an angle adjustment seat. Its specially designed nozzle and elongated air outlet form a fan-shaped high-pressure airflow with a diffusion angle of 60-80°. Combined with the limiting seat, it ensures stable airflow and can efficiently remove moisture from the surface of the workpiece.

[0013] 3. The workpiece support base of this utility model adopts a servo motor driven metal disc design, which integrates an electromagnetic adsorption system to drive the metal workpiece to rotate slowly, and together with the high-pressure airflow, forms an all-round drying treatment for the workpiece.
