[0004] The applicant found that there were some shortcomings in use: the equipment generates heat through an electric heating tube, and then uses a turbulent fan to circulate hot air in the spray box to dry the metal. Since the spray box is large, the method of heating the entire spray box is not energy-efficient and a large amount of heat is wasted.

[0005] Therefore, the utility model designs an environmentally friendly metal spraying device to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of the utility model is to provide an environmentally friendly metal spraying device to solve the problems raised in the above background technology.

Compared with the method of heating the entire processing box, the heat waste is reduced and the drying efficiency is improved.

[0008] Preferably, the clamping and rotating mechanism includes a carrying plate, which is rotatably installed in the middle of the bottom inner wall of the processing box. An electric cylinder fixedly installed on the top inner wall of the processing box is provided directly above the carrying plate. A pressure plate is rotatably installed on the output end of the electric cylinder. The electric cylinder drives the pressure plate to rise and fall, and adjusts the distance between the pressure plate and the carrying plate, so that metal pipes of different heights can be clamped, thereby improving practicality.

[0009] Preferably, the waste avoiding mechanism comprises a U-shaped rod, one side of the bottom of the U-shaped rod is fixedly connected to the top of the clamping plate, and the other side of the bottom of the U-shaped rod is slidably connected to the top of the air pipe and is installed with an adjusting plate. When the clamped pipe is shorter, the clamping plate descends, driving the U-shaped rod to descend at the same time. The U-shaped rod drives the adjusting plate to descend, making the space surface in the air pipe smaller, and the air nozzle above the adjusting plate cannot emit hot air, thereby avoiding waste of hot air. The hot air is concentrated and sprayed out from the air nozzle below the adjusting plate, which can improve the drying efficiency.

[0010] Preferably, a dust-proof net is provided in the air duct, and the dust-proof net is located above the fan. The dust-proof net protects the fan and prevents the fan blades from being adhered to a lot of dust and increasing the rotation resistance.

[0011] Preferably, a sealing disk is provided above the inner wall of the air duct, and the sealing disk blocks the top of the air duct when the device is idle to reduce dust from entering the air duct.

[0012] Preferably, the supporting plate and the pressing plate are both provided with rubber anti-skid pads at one end close to each other, and the rubber anti-skid pads can increase friction and improve the clamping effect.

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

[0014] 1. The utility model uses the air pipe and the air nozzle to generate heat. The fan blows the heat into the air pipe through the air pipe, and then sprays it out through the air nozzle. The hot air is directly sprayed on the surface of the metal pipe for drying. Compared with the method of heating the entire processing box, the heat waste is reduced and the drying efficiency is improved.

[0015] 2. The utility model avoids the setting of waste mechanism. When the metal tube is shorter, the compression plate descends, driving the U-shaped rod to descend. The U-shaped rod causes the adjustment plate to descend, making the space in the air pipe smaller. The nozzle above the adjustment plate cannot exhaust air, further avoiding the waste of hot air. The hot air is concentrated and sprayed out from the nozzle below the adjustment plate, further improving the drying efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
