[0031] In this embodiment: the drying mechanism includes a heating component for heating the interior of the drying drum 300 and a filtering component for filtering air drawn into the interior of the drying drum 300 from the outside.

[0032] The filtering component includes an air inlet bin 204 arranged above the drying cylinder 300, an exhaust fan 205 is provided at the bottom end of the air inlet bin 204, a lifting platform 207 is provided above the exhaust fan 205, a filter plate 206 is slidably installed on the upper end of the lifting platform 207, the filter plate 206 is divided into a use surface and an unused surface, and the use surface is located directly above the exhaust fan 205, baffles 209 are slidably installed on the inner walls on both sides of the air inlet bin 204, the bottom end of the baffle 209 is always in contact with the upper end of the filter plate 206, a compression spring is connected between the lifting platform 207 and the inner wall of the air inlet bin 204, a button 208 is provided below the lifting platform 207, and a cleaning component for cleaning impurities blocked on the filter plate 206 is provided above the filter plate 206.

[0033] The cleaning component includes a cleaning box 215 arranged on both sides of the air inlet bin 204 near the filter plate 206, a cylinder 210 is arranged in the cleaning box 215, a lower pressure plate 211 is arranged at the lower end of the cylinder 210, a cleaning brush 212 is rotatably installed at the lower end of the lower pressure plate 211, a friction roller 213 is arranged on the side away from the two cleaning brushes 212, a rotating motor 214 is installed at the rotating end of the cleaning brush 212, and the friction roller 213 and the cleaning brush 212 are driven by a belt.

[0034] The heating component includes a heating chamber 201 arranged at the lower end of the air inlet chamber 204, a plurality of heating rods 202 are arranged inside the heating chamber 201, a plurality of nozzles 203 are installed at the bottom end of the heating chamber 201, and the heating chamber 201 is fixedly connected to the drying cylinder 300. When the filter plate 206 is blocked, the cleaning component is used to drive the use surface of the filter plate 206 to move to one side, and the impurities on the use surface of the filter plate 206 are cleaned, so that the filter plate 206 is cleaned without hindering the normal filtering of the air on the unused side of the filter plate 206. There is no need to stop the machine to clean the filter plate 206, which improves the filtration efficiency and utilization rate of the filter plate 206 and improves the drying efficiency inside the drying cylinder 300.

[0035] Working principle: first open the cover door 302 at the front end of the drying drum 300, place the workpiece between the two clamping seats 307, rotate the bidirectional screw 306 to drive the two clamping seats 307 to move toward each other to clamp and limit the workpiece in the middle, and place multiple workpieces one by one between the multiple clamping seats 307.

[0036] Then, multiple heating rods 202 are started to heat the inside of the heating chamber 201, and at the same time, the exhaust fan 205 is driven to draw external air into the air inlet chamber 204. The filter plate 206 in the air inlet chamber 204 is used to filter dust and other impurities in the air. The filtered air enters the heating chamber 201, and the hot air is evenly sprayed onto the surface of the workpiece through multiple nozzles 203. The rotating motor 304 is driven to drive the rotating shaft 303 to rotate, and drive multiple clamped workpieces to rotate, so that each workpiece is evenly heated, thereby improving the uniformity of drying and the efficiency of drying.

[0037] After the filter plate 206 is used for a long time, a large amount of dust and other impurities will accumulate on the surface, which will affect normal filtration. After the filter plate 206 is blocked and the exhaust fan 205 is continuously working, a strong negative pressure will be formed between the exhaust fan 205 and the filter plate 206, which will drive the filter plate 206 to move downward. When the filter plate 206 moves downward, the baffle 209 will move downward with the filter plate 206, and the baffle 209 and the filter plate 206 are always in contact with each other.

The friction force generated between the friction roller 213 and the filter plate 206 will cause the used surface of the filter plate 206 to move to one side, so that the unused surface of the filter plate 206 moves to the top of the exhaust fan 205 to continue filtering the air. When the friction roller 213 rotates, it drives the cleaning brush 212 to rotate, and then the cleaning brush 212 Dust and other impurities on the used surface of the filter plate 206 are cleaned, so that the filter plate 206 is cleaned without hindering the normal filtering of the air on the unused surface of the filter plate 206. There is no need to stop the machine to clean the filter plate 206, which improves the filtration efficiency and utilization rate of the filter plate 206, and improves the drying efficiency inside the drying cylinder 300. After the used surface of the filter plate 206 is cleaned, the friction roller 213 and the cleaning brush 212 move upward and reset, and no longer press the filter plate 206 downward, and the filter plate 206 uses the release effect of the compression spring to prompt the filter plate 206 to reset upward and continue to filter the air.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
