Technical Field

[0002] Coating refers to covering a metal or non-metal surface with a protective layer or decorative layer. With the development of industrial technology, coating has evolved from manual to industrial automation and has penetrated into many areas of the national economy. Drying equipment is an important part of the coating process.

[0003] A coating drying device disclosed in the Chinese utility model patent application disclosure specification CN215390546U, although a movable lower shell is provided, the lower shell can be moved out for forming operation after drying is completed, thereby increasing the cooling speed and improving production efficiency, but the existing device lacks a device for adding cold air to slowly cool down the temperature inside the equipment box when it is too high, and a device for quickly heating it when the temperature is too low. It is very easy for the paint on the surface of the metal plate to dry and crack when the metal plate is dried due to the excessively high temperature inside the equipment box. There is also a lack of a device that can adsorb dust on the surface of the metal plate and preheat the metal plate when the metal plate enters the equipment box. It is very easy to cause the dust on the surface of the metal plate to remain in the paint after later drying due to excessive dust on the surface of the metal plate and cannot be cleaned, and the paint on the surface of the metal plate to crack due to the large difference between the temperature inside the equipment box and the temperature of the metal plate. Therefore, the present application provides a coating drying device to meet the needs. Utility Model Content

The heat pipe, the air pump and the air pipe can temporarily store the hot air after preheating and filtration and transfer it to the equipment box for circulation and filtration, avoiding the problem that the hot air inside the preheating warehouse cannot be transferred to the equipment box for circulation, filtration and drying of the metal plate.

[0018] By setting the left and right buckles, the metal plate can be placed on the surface of the support plate and the meshing distance between the right buckle and the left buckle can be manually adjusted to clamp the metal plates of different sizes, thus avoiding the problem of the metal plate loosening and falling due to the movement of the metal plate carried by the conveyor belt and the problem of the metal plate being unable to be clamped due to the different sizes of the metal plates. Through the partition, the partition can be closed after the metal plate carried by the conveyor belt enters the equipment box so that the metal plate is sealed inside the equipment box for drying, and the partition can be opened when the metal plate needs to be transferred in or out, thus avoiding the problem of dust falling when the metal plate enters the equipment box for drying and the problem of inconvenience in transferring it into the equipment box for drying due to the inability to open the partition.

[0019] By arranging the exhaust vent and the suction fan, the suction fan can rotate forward to suck the outside air into the equipment box for heating and circulation, and the used hot air can be quickly discharged after the metal plate is dried once, avoiding the problem that the outside air cannot enter the interior and the used hot air cannot be completely discharged. At the same time, the effect of quickly sucking the outside cold air into the interior to adjust the temperature when the hot temperature inside the equipment box 1 is too high can be achieved, avoiding the problem that the temperature inside the equipment box 1 cannot be quickly adjusted when it is too high or too low. Through the handle and the baffle, the effect of closing the cover when the metal plate needs to be dried, so that the metal plate and the hot air are sealed inside the equipment box for use, and opening the baffle when the equipment inside the equipment box needs to be repaired or replaced for easy replacement or maintenance can be achieved, avoiding the problem that the metal plate and the hot air cannot be sealed inside the equipment box, resulting in dust falling on the surface of the metal plate or hot air escaping and becoming unusable.

Through the exhaust port 20 and the suction fan 21, air can be sucked into the equipment box 1 and the air inside the equipment box 1 can be discharged, so that the suction fan 21 can rotate forward to suck the outside air into the equipment box 1 for heating and circulation, and the used hot air can be quickly discharged after the metal plate is dried once, avoiding the problem of dust falling into the metal plate when it enters the equipment box 1 for drying and the inconvenience of the conveyor belt 11 transferring it into the equipment box 1 for drying due to the inability to open the partition 22. The problem that air cannot enter the interior and the used hot air cannot be completely removed from the interior is solved. At the same time, when the hot temperature inside the equipment box 1 is too high, the cold air from the outside can be quickly sucked into the interior to adjust the temperature, avoiding the problem that the temperature inside the equipment box 1 cannot be quickly adjusted when it is too high or too low. Through the handle 24 and the baffle 23, the baffle 23 can be manually opened or closed on the upper surface of the equipment box 1, achieving the effect that when the metal plate needs to be dried, the baffle 23 can be closed to seal the metal plate and the hot air inside the equipment box 1 for use, and when the equipment inside the equipment box 1 needs to be repaired or replaced, the baffle 23 can be opened to facilitate replacement or maintenance, avoiding the problem that the metal plate and the hot air cannot be sealed inside the equipment box 1, resulting in dust on the surface of the metal plate or hot air escaping and being unusable.
