[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figure 1-5As shown, this utility model provides a technical solution: a sheet metal spray painting drying device, including a drying chamber 1, four filters 2 installed inside the drying chamber 1, and multiple hanging hooks 3 installed at the top of the drying chamber 1. Air inlets 4 are provided on the upper and lower side walls and the left and right side walls of the drying chamber 1. An air inlet box 8 and an air outlet box 9 are respectively provided at the top and bottom of the drying chamber 1, and connecting holes 10 are provided on the opposite surfaces of the air inlet box 8 and the air outlet box 9. The rear sides of the air inlet box 8 and the air outlet box 9 are connected by a bracket 11, and the rear ends of the air inlet box 8 and the air outlet box 9 are connected by a connecting pipe 12. The painted sheet metal can be suspended inside the drying chamber 1 by the hanging hooks 3. The airflow from the air pump 14... The corresponding exhaust box 9 is extracted, and the gas inside the drying chamber 1 is extracted through the exhaust box 9, the docking hole 10, and the air supply hole 4. The airflow pumping end of the air pump 14 is connected to the connecting pipe 12. The airflow pumped by the air pump 14 passes through the connecting pipe 12 and the air inlet box 8 and re-enters the drying chamber 1. During this process, the heating wire 13 heats the airflow, delivering hot air to the drying chamber 1 to dry the sheet metal. A filter pipe 15 is installed on the connecting pipe 12, and a gas purification material is installed inside the filter pipe 15. The gas purification material can be a moisture-absorbing material to absorb moisture in the gas. The heating wire 13 is installed on the rear side of the air inlet box 8, and the air pump 14 is installed on the rear side of the exhaust box 9. The airflow pump 14 extracts the gas... The air pump 14 is connected to the connecting pipe 12 at the outlet end of the exhaust box 9. The air pumped out by the air pump 14 enters the drying chamber 1 through the connecting pipe 12 and the air inlet box 8 in sequence. A positioning shaft 16 is installed in the middle of the bracket 11 and is mounted on the base 18. The positioning shaft 16 is driven by the motor 17. The motor 17 can also drive the air inlet box 8 and the exhaust box 9 to rotate 90 degrees through the bracket 11, aligning the air inlet box 8 and the exhaust box 9 with the other air outlets 4 of the drying chamber 1. This achieves hot air circulation in different directions on the upper and lower sides and the left and right sides of the drying chamber 1, making the drying of sheet metal paint more uniform. The upper and lower outer walls and the left and right outer walls of the drying chamber 1 are all covered with... A sealing plate 5 is provided, and the sealing plate 5 is driven by an electric push rod 6. The sealing plate 5 has an air inlet 7. The air inlet box 8 and the exhaust box 9 are in contact with the sealing plate 5. The air inlet 7 on the sealing plate 5 corresponds to the docking hole 10 on the air inlet box 8 and the exhaust box 9. When the air inlet box 8 and the exhaust box 9 are not in contact with the sealing plate 5, the sealing plate 5 slides under the drive of the electric push rod 6, and the air inlet 7 is misaligned with the air outlet 4, so as to block the air outlet 4 through the sealing plate 5. The sealing plate 5 has a sliding groove on both sides, and an L-shaped sliding strip slides in the sliding groove. The sliding strip is connected to the drying box 1. The setting of the sliding groove and the sliding strip can make the sealing plate 4 move stably with the extension end of the electric push rod 6.

[0023] The operational steps for this application are as follows:

[0024] The painted sheet metal can be suspended in the drying chamber 1 by the suspension hook 3. The air pump 14 draws air from the corresponding exhaust box 9. The air in the drying chamber 1 is extracted through the exhaust box 9, the docking hole 10 and the air supply hole 4. The air pumping end of the air pump 14 is connected to the connecting pipe 12. The air pumped out by the air pump 14 enters the drying chamber 1 again through the connecting pipe 12 and the air inlet box 8. During this process, the heating wire 13 heats the air and delivers hot air to the drying chamber 1 to dry the sheet metal.

[0025] The motor 17 can also drive the air intake box 8 and the exhaust box 9 to rotate 90 degrees through the bracket 11, so that the air intake box 8 and the exhaust box 9 correspond to the other air outlets 4 of the drying box 1, so that the hot air circulation can be carried out in different directions on the upper and lower sides and the left and right sides of the drying box 1, making the drying of sheet metal after painting more uniform.
