The upper end of the fixed insulation plate is connected to the transverse part of the n-shaped frame 21, and the two ends of the fixed insulation plate are respectively connected to the two vertical parts of the n-shaped frame 21. A guide plate 24 is vertically arranged on each of the two vertical parts of the n-shaped frame 21, and a vertical guide groove is arranged on the guide plate 24. The two sides of the lifting insulation plate 23 are respectively located in the vertical guide grooves of the two guide plates 24. The lifting cylinder 22 can use any one of a cylinder, a hydraulic cylinder, and an electric cylinder. There are two lifting cylinders 22 , which are vertically arranged on the transverse part of the n-shaped frame 21 , and are symmetrically arranged on both sides of the middle position of the lifting insulation board 23 , and the piston rods of the lifting cylinders 22 are connected to the lifting insulation board 23 .

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, the hot air supply device 3 includes a shell 31, an electric heating pipe 32, a fan 33, an air supply pipe 34 and a return air pipe 35. The shell 31 is arranged on one side of the curing chamber 1, and the shell 31 has an air inlet and an air outlet. A plurality of electric heating pipes 32 are arranged in the shell 31, and each electric heating pipe 32 is arranged in a matrix. The air supply pipe 34 is a square tube structure, and the air supply pipe 34 is arranged at the inner top of the curing chamber 1, and air supply holes are arranged on the lower wall of the air supply pipe 34. One end of the air supply pipe 34 is opened, and the end is connected to the air outlet of the shell 31. The return air pipe 35 is arranged at the inner bottom of the curing chamber 1, and a return air port is arranged on the pipe wall of the return air pipe 35. One end of the return air pipe 35 is connected to the air suction port of the fan 33, and the air outlet of the fan 33 is connected to the air inlet of the shell 31. The fan 33 uses a high temperature resistant fan. The fan 33 sucks the air in the curing chamber 1 through the return air pipe 35, and then sends it into the shell 31, blowing it to the electric heating pipes 32 arranged in the shell 31 to form hot air. The hot air enters the air supply pipe 34 through the air outlet of the shell 31, and then enters the curing chamber 1 evenly through the air supply holes arranged on the lower wall of the air supply pipe 34, and solidifies the powder on the surface of the aluminum alloy high-pressure composite gas cylinder entering the curing chamber 1. It can be seen that the hot air supply device 3 is a circulating heating device, which is more energy-saving.

[0027] Since the chain conveyor will bring powder into the curing chamber 1 with the aluminum alloy high-pressure composite gas cylinder, and the air in the curing chamber 1 is sucked in by the fan 33 through the return air duct 35, which will also carry powder, a replaceable filter device is provided between the return air duct 35 and the air inlet of the fan 33, and the filter device is used to filter the powder in the inhaled air.

[0030] like Figure 1 As shown, the inlet and outlet of the curing chamber 1 are each provided with a mounting frame 4, and an exhaust gas suction hood 5 is provided on the mounting frame 4. The exhaust gas suction hood 5 is connected to an exhaust gas suction fan through a pipeline. In this way, the exhaust gas generated during the powder curing process can be sucked away by the exhaust gas suction fan and the exhaust gas suction hood 5 to prevent the exhaust gas from leaking out, which helps to maintain the air environment of the production workshop.

[0031] The working principle of the utility model is as follows: an inlet is provided at one end of the curing chamber 1, and an outlet is provided at the other end, and a chain conveyor passes through the inlet and outlet of the curing chamber 1.

At the same time, the hot air supply device 3 is started to send hot air into the curing chamber 1 to cure the powder on the surface of the aluminum alloy high-pressure composite gas cylinder entering the curing chamber 1. After the curing is completed, the lifting cylinder 22 of the lifting door device 2 is started, and the lifting cylinder 22 drives the lifting insulation plate 23 to rise, leaving enough space for the chain conveyor to transport the aluminum alloy high-pressure composite gas cylinder.
