[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model provides a better coating effect for the coil by setting a coating mechanism, and can dry the coil, and can add coating liquid inside the coating pool. After the coil is placed inside the clamping mechanism and clamped and fixed, the hydraulic cylinder is started to make the movable plate drive the clamping mechanism and the coil to move downward, so that the coil can pass through the feeding port into the coating pool to start the coating process. During this period, the first motor and the water pump can be in a running state, and the first motor can drive the coil to rotate through the clamping mechanism. The rotation of the coil enables it to contact the coating liquid evenly and comprehensively during the coating process, greatly improving the uniformity of coating, and the water pump extracts the coating liquid at the bottom of the coating pool and transports it upward for reflux, which is beneficial to the circulation of the coating liquid, and can improve the coating effect. rate, and avoid the precipitation of paint liquid, keep the paint liquid composition uniform, so as to improve the dipping effect. After the dipping is completed, reset the hydraulic cylinder and let the coil stand for a while to allow the excess paint liquid to drip naturally. Then start the hot air blower and the first motor to allow the hot air to blow toward the rotating coil through the shunt pipe. This will not only help the paint liquid to evaporate quickly and improve the uniformity of heating on the coil surface, but also promote the synchronous curing of the inside and outside of the paint film, reduce stress and improve the quality of the paint film. Then start the infrared heating tube. Infrared heating has good penetrating ability and can heat deeply inside the paint film to accelerate the curing process. Using it after the initial drying of the hot air can more effectively promote the thorough drying of the paint film and improve the insulation performance and mechanical strength of the paint film.

[0015] 2. The utility model sets a clamping mechanism so that coils of various sizes can obtain a limiting effect. The second motor can drive the connecting frame to rotate, so that the coil clamped on the surface of the bottom plate can rotate. When the coil needs to be limited, the first screw is rotated to make the sliding sleeve move upward under the influence of the thread. At this time, the hinge angle of the linkage plate, the sliding sleeve and the clamping plate will change, so that the linkage plate can rotate, thereby forcing the multiple clamping plates to move toward each other, so that the coil can obtain a clamping effect, and the relative movement of the multiple clamping plates enables the device to be flexibly adjusted according to the size of the coil, which is suitable for coils of different specifications and shapes, thereby improving the versatility of the equipment.

[0016] 3. The utility model sets a shielding mechanism so that the paint immersion pool can be closed. When the drying process is carried out, the second motor is started to rotate the second screw. At this time, the sliding seat can be affected by the thread to drive the blocking plate to move toward the position above the feeding port, so that the blocking plate can close the top of the feeding port. The closed paint immersion pool can significantly reduce the large amount of evaporation caused by the paint liquid being exposed to the air when not in use, which is more conducive to saving resources and environmental protection. At the same time, it also makes it difficult for hot air to be transmitted to the inside of the paint immersion pool through the feeding port, thereby reducing the impact of hot air on the paint liquid inside the paint immersion pool.

[0026] Paint liquid can be added to the paint immersion pool 105. After the coil is placed in the clamping mechanism 2 and clamped and fixed, the hydraulic cylinder 102 is started to make the movable plate 103 drive the clamping mechanism 2 and the coil to move downward, so that the coil can pass through the feeding port 113 and enter the paint immersion pool 105 to start the paint immersion process. During this period, the first motor 104 and the water pump 110 can be in operation. The first motor 104 can drive the coil to rotate through the clamping mechanism 2. The rotation of the coil enables it to be evenly and comprehensively contacted with the paint liquid during the paint immersion process, which greatly improves the uniformity of the paint immersion. The water pump 110 extracts the paint liquid at the bottom of the paint immersion pool 105 and transports it back upward, which is conducive to the circulation of the paint liquid, which can not only improve the paint immersion efficiency but also avoid the precipitation of the paint liquid. , keep the paint liquid composition uniform, so as to improve the paint dipping effect. When the paint dipping is completed, reset the hydraulic cylinder 102, and let the coil stand for a while to allow the excess paint liquid to drip naturally, and then start the hot air blower 107 and the first motor 104, so that the hot air can be blown toward the rotating coil through the shunt pipe 108, which not only helps the paint liquid to evaporate quickly and improve the uniformity of heating on the coil surface, but also promotes the synchronous curing of the inside and outside of the paint film, reduces stress, and improves the quality of the paint film.
