When the motor rotates forward, the rubber bag shortens and sprays the material from the nozzle and smears it on the drying cylinder. When the motor rotates reversely, the rubber bag extends, forming a negative pressure material that is sucked into the rubber bag, thereby realizing continuous feeding operation.

[0024] 2. When the motor rotates forward, it will drive the driving gear to rotate, and the driving gear will drive the first gear, the first threaded rod and the sliding plate to move, so that the material is smeared on the surface of the drying cylinder. When the motor rotates reversely, the smearing plate can scrape off the residue on the surface of the drying cylinder to prevent uneven smearing next time.

[0025] 3. When the motor rotates forward, it will drive the driving gear to rotate, and the driving gear will drive the second gear, the second threaded rod and the sliding block to rotate, thereby driving the roller to rotate. The rotation of the roller drives the clutch, the first connecting rod, the turntable and the second connecting rod to rotate, thereby driving the rotating plate to reciprocate. The reciprocating rotation of the rotating plate drives the scraper to reciprocate, thereby scraping off the material on the drying cylinder. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] When the driving gear 302 rotates forward, the driving gear 302 drives the second gear 402 to rotate, the second gear 402 drives the second threaded rod 401 to rotate, the second threaded rod 401 drives the sliding block 403 to move leftward, and when the sliding block 403 moves leftward, the roller 408 is driven to rotate. Due to the action of the clutch 407, the rotation of the roller 408 will not drive the first connecting rod 406 to rotate, and thus will not drive the scraper 412 to move up and down, so as to prevent the undried materials on the drying cylinder 210 from being scraped off during the leftward movement. When the driving gear 302 rotates reversely, the driving gear 302 drives the second gear 402 to rotate, the second gear 402 drives the second threaded rod 401 to rotate, the second threaded rod 401 drives the sliding block 403 to move rightward, and the sliding block 403 moves rightward to drive the scraper 412 to move rightward, and at the same time drives the roller 408 to rotate. When the scraper 412 moves to the right, the scraper 412 rotates to the right and cooperates with the drying cylinder 210 to scrape off the materials on the drying cylinder 210. The scraped materials fall into the bottom of the sealing cylinder 202 and then enter the collection box 201 from the collection pipe 203. When the roller 408 rotates, the roller 408 drives the clutch 407 to rotate, the clutch 407 drives the first connecting rod 406 to rotate, the first connecting rod 406 drives the rotating disk 409 to rotate, the rotating disk 409 drives the second connecting rod 410 to rotate, the second connecting rod 410 rotates the rotating rod 205 drives the rotating plate 411 to reciprocate, the reciprocating rotation of the rotating plate 411 drives the scraper 412 to reciprocate, thereby increasing the efficiency of scraping off the materials on the surface of the drying cylinder 210, The clutch 407 is a one-way overrunning clutch.

[0046] The one-way overrunning clutch 407 allows the first connecting rod 406 to rotate in only one direction.

[0047] The roller 408 is made of rubber.

[0048] The roller 408 is made of rubber material, which can increase the friction between the roller 408 and the inner wall of the sealing tube 202 and prevent the roller 408 from slipping.

[0049] Working principle: When the work starts, the staff turns on the motor 206 and the heater 211. When the staff turns on the motor 206, the motor 206 rotates forward. When the work starts, the staff turns on the motor 206 and the heater 211. When the staff turns on the motor 206, the motor 206 rotates and performs periodic forward and reverse rotations. The rotation of the motor 206 drives the driving wheel 207 to rotate. The rotation of the driving wheel 207 drives the belt 209 to rotate. The rotation of the belt 209 drives the driven wheel 208 to rotate. The driven wheel 208 rotates the rotating rod 205. The rotating rod 205 rotates and drives the driving wheel 207 to rotate. The driving gear 302 rotates and the drying cylinder 210 rotates. When the driving gear 302 rotates, the driving gear 302 rotates to drive the first gear 303 to rotate, and the first gear 303 rotates to drive the first threaded rod 301 to rotate. The first threaded rod 301 rotates to drive the sliding plate 305 to move rightward, and the sliding plate 305 moves rightward to drive the connecting plate 311 and the nozzle 306 to move rightward. When the connecting plate 311 moves rightward, the rubber bag 310 is squeezed. After the rubber bag 310 is squeezed, the material in the rubber bag 310 is sprayed on the drying cylinder 210 from the nozzle 306 through the discharge pipe 314. When the drying cylinder 210 rotates, the drying cylinder 210 carries the material on the surface through the heater 211, thereby drying the material. When the driving gear 302 rotates forward, the driving gear 302 drives the second gear 402 to rotate, and the rotation of the second gear 402 drives the second threaded rod 401 to rotate. The rotation of the second threaded rod 401 drives the sliding block 403 to move leftward. When the sliding block 403 moves leftward, it drives the roller 408 to rotate. Due to the action of the clutch 407, the rotation of the roller 408 will not drive the first connecting rod 406 to rotate, and thus will not drive the scraper 412 to move up and down, so as to prevent the undried material on the drying cylinder 210 from being scraped off during the movement to the left.

[0050] When the motor 206 rotates in the opposite direction, the motor 206 drives the rotating rod 205 to rotate, and the rotating rod 205 drives the driving gear 302 and the drying cylinder 210 to rotate. When the driving gear 302 rotates, the driving gear 302 drives the first gear 303 to rotate, and the first gear 303 drives the first threaded rod 301 to rotate. The rotation of the first threaded rod 301 drives the sliding plate 305 to move leftward, and the sliding plate 305 moves leftward and drives the connecting plate 311 to move leftward. The connecting plate 311 moves leftward and drives the rubber bag 310 to extend. The rubber bag 310 extends to suck the material in the storage box 312 from the feeding pipe 313 into the rubber bag 310 until the sliding plate 305 moves to the leftmost end. When the driving gear 302 rotates in the opposite direction, the driving gear 302 drives the second gear 402 to rotate, the second gear 402 drives the second threaded rod 401 to rotate, the second threaded rod 401 rotates and drives the sliding block 403 to move rightward, the sliding block 403 moves rightward and drives the scraper 412 to move rightward, and drives the roller 408 to rotate at the same time. When the scraper 412 moves rightward, the scraper 412 rotates rightward and cooperates with the drying cylinder 210 to scrape off the material on the drying cylinder 210, and the scraped material falls to the bottom of the sealing cylinder 202, and then enters the collection box 201 from the collection pipe 203. When the roller 408 rotates, the roller 408 drives the clutch 407 to rotate, the clutch 407 drives the first connecting rod 406 to rotate, the first connecting rod 406 drives the turntable 409 to rotate, the turntable 409 drives the second connecting rod 410 to rotate, the second connecting rod 410 rotates the rod 205 drives the rotating plate 411 to rotate back and forth, the rotating plate 411 drives the scraper 412 to rotate back and forth, thereby increasing the efficiency of scraping off the material on the surface of the drying cylinder 210 and preventing the material from remaining on the drying cylinder 210 and affecting the subsequent coating process.
