However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0025] As Figures 1-5As shown in the figure, the utility model provides a low-temperature drying device for powder coating preparation, including: a device body 1, and a protection mechanism 2 is arranged on the device body 1;

[0026] The protection mechanism 2 includes a rectangular frame 201. Rectangular plates 202 are fixed on both sides of the rectangular frame 201. A frame 203 is arranged on the front surface of the rectangular frame 201. A porous plate 204 is fixed inside the frame 203. Four single-hole blocks 205 are fixed on the front surface of the rectangular frame 201. Flat plates 206 are arranged on both sides of the frame 203. Cylindrical grooves 207 are opened on both sides of the frame 203. Springs 208 are installed on the inner walls of each cylindrical groove 207. Two rectangular blocks 209 are fixed on the relative side of the two flat plates 206. Four first rectangular grooves 210 are opened on the front surface of the frame 203. Two second rectangular grooves 211 are opened on both sides of the frame 203. The rear surface of the rectangular frame 201 is fixed to the front surface of the device body 1. Each single-hole block 205 is respectively movably sleeved inside each first rectangular groove 210. The opposite ends of the two springs 208 are respectively installed on the relative side of the two flat plates 206. Each rectangular block 209 is respectively movably sleeved inside each second rectangular groove 211. The inside of each first rectangular groove 210 is respectively communicated with the inside of each second rectangular groove 211. Each rectangular block 209 is respectively movably sleeved inside the through holes of each single-hole block 205. An auxiliary mechanism 3 is arranged on the protection mechanism 2. The auxiliary mechanism 3 includes two perforated blocks 301 and two threaded grooves 303. A hand-tightening bolt 302 is movably sleeved inside each perforated block 301. Two symmetrically arranged L-shaped blocks 304 are fixed on the surface of each perforated block 301. Two threaded grooves 303 are respectively opened on the front surface of the rectangular plate 202. The threaded ends of each hand-tightening bolt 302 are respectively threadedly connected inside each threaded groove 303. The surface of each L-shaped block 304 is in contact with the surface of the frame 203.

[0027] The achieved effect is that when the glass on the observation window of the low-temperature drying equipment for powder coating preparation needs to be replaced, first remove the two hand-tightening bolts 302 from the two threaded grooves 303 respectively. At this time, the moving hand-tightening bolts 302 will drive the corresponding perforated blocks 301 to move, and the moving perforated blocks 301 will drive the corresponding L-shaped blocks 304 to move. When the two hand-tightening bolts 302 have both completed the moving operation, first apply a force to the two flat plates 206 to make the two flat plates 206 move in opposite directions. At this time, the moving flat plates 206 will drive the corresponding rectangular blocks 209 to move. At the same time, the moving flat plates 206 will, in cooperation with the cylindrical grooves 207, cause the corresponding springs 208 to undergo elastic deformation. When the four rectangular blocks 209 have completely moved out of the corresponding second rectangular grooves 211, stop the movement of the two flat plates 206. Then move the frame 203. At this time, the moving frame 203 will drive the two flat plates 206, the two springs 208, the four rectangular blocks 209 and the perforated plate 204 to move together. At the same time, the moving frame 203 will also separate from the surface of the rectangular frame 201. When the four single-hole blocks 205 have all moved out of the corresponding first rectangular grooves 210, stop the movement of the frame 203. Then release the force applied to the two flat plates 206 at the same time. At this time, the two flat plates 206 will return to their original positions under the cooperation of the corresponding cylindrical grooves 207 and the resilience of the corresponding springs 208. At this time, the two flat plates 206 that have returned to their original positions will drive the corresponding rectangular blocks 209 to move together. Then move the frame 203 away. Then the observation window glass on the low-temperature drying equipment for powder coating preparation can be replaced. When the replacement operation of the observation window glass on the equipment is completed, then perform the reverse operation according to the above operation steps until all the above components return to their original positions.

[0028] Working principle: When the glass on the observation window of the low-temperature drying equipment for powder coating preparation needs to be replaced, first remove the two hand-tightening bolts 302 from the two threaded grooves 303 respectively. At this time, the moving hand-tightening bolts 302 will drive the corresponding perforated blocks 301 to move, and the moving perforated blocks 301 will drive the corresponding L-shaped blocks 304 to move. When the two hand-tightening bolts 302 have completed the moving operation, first apply a force to the two flat plates 206 to make the two flat plates 206 move in opposite directions. At this time, the moving flat plates 206 will drive the corresponding rectangular blocks 209 to move. At the same time, the moving flat plates 206 will, in cooperation with the cylindrical grooves 207, cause the corresponding springs 208 to undergo elastic deformation. When the four rectangular blocks 209 have completely moved out of the corresponding second rectangular grooves 211, stop the movement of the two flat plates 206. Then move the frame 203. At this time, the moving frame 203 will drive the two flat plates 206, the two springs 208, the four rectangular blocks 209 and the perforated plate 204 to move together. At the same time, the moving frame 203 will also separate from the surface of the rectangular frame 201. When the four single-hole blocks 205 have moved out of the corresponding first rectangular grooves 210, stop the movement of the frame 203. Then release the force applied to the two flat plates 206 at the same time. At this time, the two flat plates 206 will return to their original positions under the cooperation of the corresponding cylindrical grooves 207 and the resilience of the corresponding springs 208. At this time, the two flat plates 206 that have returned to their original positions will drive the corresponding rectangular blocks 209 to move together. Then move the frame 203 away. Then the observation window glass on the low-temperature drying equipment for powder coating preparation can be replaced. When the replacement operation of the observation window glass on the equipment is completed, perform the reverse operation according to the above operation steps until all the above components return to their original positions.

[0029] Among them, the equipment body 1 is the low-temperature drying equipment for powder coating preparation, which includes the following main components:

[0030] Drying chamber: Provide a drying space to accommodate the powder coating to be dried.

[0031] Heating system: Generally, electric heating, steam heating or hot fluid heating is used to provide the heat required for the drying process.

[0032] Circulation fan: Promote the air circulation in the drying chamber to ensure uniform heat distribution.

[0033] Temperature sensor: Real-time monitor the temperature in the drying chamber and feedback it to the control system to accurately control the temperature.

[0034] Humidity sensor: Detect the humidity in the drying chamber to help judge the drying process.

[0035] Control system: It includes a control panel and a control circuit, which are used to set and adjust parameters such as drying temperature and time.

[0036] Air ducts and vents: They guide the flow path of the air current to ensure the reasonable circulation of air.

[0037] Tray or conveyor belt: It is used to place the powder coating so that it can be evenly heated in the drying chamber.

[0038] Observation window: It is used to observe the drying situation of the material.

[0039] Its working principle is as follows:

[0040] The low-temperature drying equipment heats the air to an appropriate low temperature (usually lower than the temperature of traditional drying equipment) through the heating system. The circulation fan makes the heated air circulate in the drying chamber, evenly contacting the powder coating to be dried. The moisture on the surface of the powder coating gradually evaporates in the low-temperature environment, and the moisture is discharged from the drying chamber. The staff can observe the drying situation of the powder coating in the equipment through the observation window at any time. The temperature sensor and humidity sensor monitor the temperature and humidity in the drying chamber in real time and feed the data back to the control system. The control system adjusts the heating power, fan speed, etc. according to the preset parameters to ensure that the drying process is carried out under ideal conditions until the powder coating reaches the required drying degree.
