Description

Technical Field

[0001] The invention belongs to the technical field of high-voltage electrical equipment manufacturing, and in particular relates to a coating and leveling device and a method for using the same. Background Art

[0002] In the high-voltage electrical industry, the insulating rubber coating process is one of the key technologies to ensure the safe and stable operation of electrical equipment. Its main function is to form an insulating layer on the surface of electrical equipment to prevent safety hazards such as current leakage, short circuit and electric shock. By improving the insulation strength of the equipment, insulating rubber coating can not only extend the service life of the equipment, but also effectively reduce maintenance costs. Commonly used insulating rubber materials, such as silicone rubber and nitrile rubber, are widely used in this field due to their excellent insulation properties, high and low temperature resistance, flame retardancy and wear resistance.

[0003] At present, the insulating rubber coating process mainly relies on traditional coating methods, which require the coating material to be evenly attached to the surface of the workpiece and cured. Common coating techniques include spraying, dipping and brushing. These methods can theoretically achieve uniform coverage of the insulating layer, but in actual operation, the uniformity and thickness control of the coating are often difficult to accurately grasp. In addition, the organic solvent in the coating material will volatilize during the coating process. If the volatilization is not complete, it may cause defects such as bubbles and cracks in the coating layer, thereby affecting the insulation performance. Although the existing insulating rubber coating technology can meet the insulation requirements of electrical equipment to a certain extent, there are still some problems that need to be solved. First, it is difficult to ensure the uniformity and thickness consistency of the coating material during the coating process, especially on the surface of complex-shaped workpieces, the problem of uneven coating is more prominent. Secondly, the incomplete volatilization of the organic solvent in the coating material may cause residual solvent in the coating layer, affecting the insulation performance and mechanical strength of the coating layer. In addition, improper control of temperature and time during the curing process may also cause defects in the coating layer, further affecting the long-term stable operation of the equipment.

[0004] Therefore, it is of great practical significance to develop a coating and leveling equipment that can effectively solve the problems of uneven coating and incomplete volatilization of organic solvents. Summary of the invention

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a coating leveling device and a method of using the same, so as to solve the technical problems of uneven coating and incomplete volatilization of organic solvents affecting the coating quality in the existing insulating rubber coating process.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: The present invention discloses a coating leveling device, comprising: a bracket, a rotating shaft installed inside the bracket, a rotary support body movably installed on the rotating shaft, and a leveling fan installed below the rotary support body; There are two rows of rotary support bodies, and the workpiece is placed above the two rows of rotary support bodies; the leveling fan blows air upward.

[0007] Preferably, a rotary speed reducer is installed at one end of the rotating shaft.

[0008] Preferably, the rotary support body is fixed on the rotating shaft by a setscrew.

[0009] Preferably, the rotary support body is made of nylon material.

[0010] Preferably, the rotary support body is provided with at least two layers.

[0011] Preferably, an exhaust hood and an exhaust pipe are arranged above the rotary support body, and the exhaust pipe is connected to an outdoor waste gas treatment system.

[0012] Preferably, the leveling fan is a small axial flow fan.

[0013] The present invention also discloses a method for using the coating leveling device. The coating leveling is carried out by using the above coating leveling device, and the method comprises the following steps: 1) Place the coated workpiece on the rotary support body; 2) Adjust the rotating speed of the rotating shaft to make the workpiece rotate uniformly; 3) Start the leveling fan to blow air upward; 4) After leveling is completed, send the workpiece into a curing furnace for curing.

[0014] Preferably, the wind speed of the leveling fan is controlled at 2 - 3 m / s.

[0015] Preferably, the rotating speed of the rotating shaft is controlled by frequency conversion adjustment.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention discloses a coating leveling device, which provides stable support through a bracket to ensure the stability of the device operation; provides a stable foundation to prevent the device from shaking or tilting during operation; ensures that the workpiece remains stable during rotation and leveling, avoiding uneven coating or glue splashing. The rotating shaft cooperates with the rotary support body to realize the rotation of the workpiece. Through the rotation of the rotating shaft, the workpiece is driven to rotate at a constant speed, so that the coating material is evenly distributed on the surface of the workpiece. The rotational movement promotes the leveling of the coating material and reduces coating defects such as bubbles and sagging; the rotary support body supports the workpiece and rotates with the rotating shaft. The movable installation design enables the rotary support body to move along the rotating shaft to adapt to workpieces of different lengths, improving the versatility of the device; the design of two rows of rotary support bodies ensures that the workpiece remains balanced during rotation, avoiding eccentricity or vibration, being applicable to workpieces of various specifications, and improving the applicability of the device. The leveling fan blows air upwards to accelerate the volatilization of the solvent on the surface of the workpiece. The upward blowing design directly acts on the surface of the workpiece, promoting the uniform volatilization of the solvent, avoiding excessive or too slow local volatilization, improving the coating quality, ensuring that the coating is dense and smooth, and meeting the insulation performance requirements; by controlling the wind speed, it is avoided that too large a wind speed causes unevenness on the surface of the coating or too small a wind speed causes insufficient volatilization.

[0017] Further, a rotary reducer is installed at one end of the rotating shaft. The rotary reducer adjusts the rotation speed of the rotating shaft to adapt to different workpiece sizes and coating material characteristics, optimizing the leveling effect.

[0018] Further, the rotary support body is fixed on the rotating shaft by a setscrew. The setscrew design enables the rotary support body to move along the rotating shaft, flexibly adapting to workpieces of different lengths and improving the versatility of the device.

[0019] Further, the rotary support body is made of nylon material. The nylon material avoids abrasion on the surface of the workpiece, protects the integrity of the coating, and ensures the insulation performance.

[0020] Further, the rotary support body is provided with at least one layer. The multi-layer structure improves the space utilization rate, supports batch processing, and improves the production efficiency.

[0021] Further, an exhaust hood and an exhaust pipe are arranged above the rotary support body. The exhaust pipe is connected to an outdoor waste gas treatment system. The exhaust hood and the exhaust pipe effectively collect and discharge volatile gases, ensuring the safety of the operating environment and meeting the environmental protection requirements.

[0022] Further, the leveling fan is a small axial flow fan. The small axial flow fan is small in size and high in efficiency, providing a uniform wind speed, promoting the volatilization of the solvent, and improving the coating quality.

[0023] The present invention also discloses a method of using a coating leveling device. Place the coated workpiece on the rotary support. The rotary support provides a stable support platform for the workpiece, ensuring that the workpiece does not shake or fall during rotation. Adjust the rotation speed of the rotary shaft to make the workpiece rotate at a uniform speed. Uniform rotation can ensure that the coating on the workpiece surface is evenly distributed, avoiding local accumulation or uneven thickness, and helping to reduce coating defects such as ripples and wrinkles caused by uneven rotation speed. By adjusting the rotation speed of the rotary shaft, the speed of the leveling process can be precisely controlled to meet the requirements of different coatings and workpieces. Start the leveling fan to blow air upward. The airflow generated by the leveling fan can accelerate the flow of the coating on the workpiece surface, thereby shortening the leveling time. The airflow can help eliminate tiny bubbles and wrinkles on the coating surface, improving the flatness and gloss of the coating. It can also promote the uniform drying of the coating, avoiding problems caused by local over-fast or over-slow drying. Through curing, the hardness, wear resistance, and corrosion resistance of the coating can be further improved, thereby extending the service life of the workpiece.

[0024] Further, the wind speed of the leveling fan is controlled at 2 - 3 m / s to balance the evaporation efficiency and coating stability, preventing surface cracking or sagging.

[0025] Further, the rotation speed of the rotary shaft is controlled by frequency conversion adjustment. Frequency conversion adjustment enables precise control, adapts to different workpiece sizes and coating material characteristics, and optimizes the leveling effect. Description of the Drawings

After rotating for a period of time, it can ensure that the coating material is evenly attached to the workpiece 3; at the same time, the rotation process can volatilize the volatile solvents in the coating material. When the amount of organic solvent in the coating material applied to the workpiece 3 decreases and then enters the curing furnace, only a small amount of residual organic solvent needs to be volatilized in the curing furnace at this time, so that the quality of the insulating rubber coated on the workpiece 3 is better.
