[0004] Regarding the above related technologies, when producing rhinestones (workpieces), there is usually already solidified glue on the outside. After putting the workpiece and abrasive into the vortex polishing machine together, the glue can be separated from the workpiece and form waste. When the processing is completed, the workpiece, abrasive, and waste need to be separated. Currently, it is usually manually screened, and multiple screenings are required, with a large screening intensity. Summary of the Invention

[0005] In order to reduce the screening intensity, this application provides a vortex surface degumming method and degumming equipment.

[0006] In the first aspect, this application provides a vortex surface degumming method, adopting the following technical solution: A vortex surface degumming method includes the following steps: S1: Put the workpiece and abrasive into the grinding tank of the vortex polishing machine together. Through the high-speed rotation of the rotating disk, a vortex motion is generated, enabling the workpiece and abrasive to fully friction, separating the workpiece from the waste. During the grinding process, the fine impurities generated by grinding are carried away by the circulating water flow; S2: After the grinding is completed, pour the workpieces, abrasives, and waste in the grinding tank onto the upper screen assembly of the sieve box, and stir the materials on the upper screen assembly through the upper stirring assembly. The upper screen assembly screens the abrasives in the materials, causing the sieved workpieces and waste to fall onto the lower screen assembly, and screening the abrasives outside the sieve box; S3: The lower stirring assembly stirs the materials on the lower screen assembly. The lower screen assembly screens the abrasives in the materials, causing the sieved waste to fall to the bottom inside the sieve box, and screening the workpieces outside the sieve box.

[0007] By adopting the above technical solution, the workpieces, abrasives, and waste in the grinding tank are poured into the sieve box together, causing the workpieces, abrasives, and waste to fall onto the upper screen assembly. Then, the upper stirring assembly stirs the materials on the upper screen assembly. The upper screen assembly screens the abrasives in the materials, causing the sieved workpieces and waste to fall onto the lower screen assembly, and screening the abrasives outside the sieve box. The lower stirring assembly stirs the materials on the lower screen assembly. The lower screen assembly screens the waste in the materials, causing the sieved waste to fall to the bottom inside the sieve box, and screening the workpieces outside the sieve box, thereby realizing the separation of abrasives, workpieces, and waste.

[0008] In a second aspect, the present application provides a vortex surface degumming device, adopting the following technical solution: It includes a vortex finishing machine for processing workpieces and a vibration separation mechanism arranged below the vortex finishing machine. The vibration separation mechanism includes: A sieve box located below the vortex finishing machine; An upper screen assembly arranged in the upper middle part of the sieve box, screening the abrasives in the materials, and causing the sieved workpieces and waste to fall onto the lower screen assembly; An upper stirring assembly arranged inside the sieve box and above the upper screen assembly, stirring the materials on the upper screen assembly; A lower screen assembly arranged in the lower middle part of the sieve box, screening the workpieces in the materials, and causing the waste to fall to the bottom inside the sieve box; A lower stirring assembly arranged inside the sieve box and between the upper screen assembly and the lower screen assembly, stirring the materials on the lower screen assembly.

[0009] By adopting the above technical solution, the workpieces, abrasives, and waste materials in the grinding tank are poured into the sieve box together, so that the workpieces, abrasives, and waste materials fall to the upper sieve assembly. Then, the upper stirring assembly stirs the materials on the upper sieve assembly. The upper sieve assembly screens the abrasives in the materials, so that the screened workpieces and waste materials fall onto the lower sieve assembly, and the abrasives are screened outside the sieve box. The lower stirring assembly stirs the materials on the lower sieve assembly. The lower sieve assembly screens the waste materials in the materials, so that the screened waste materials fall to the inner bottom of the sieve box, and the workpieces are screened outside the sieve box, thereby realizing the separation of abrasives, workpieces, and waste materials.

[0010] Optionally, the upper stirring assembly includes a sun gear arranged at the inner top of the sieve box, an internal gear ring rotatably connected to the inner top of the sieve box, a plurality of annular sliders slidably connected to the inner top of the sieve box, a planetary gear rotatably connected to the bottom of the annular slider, and an upper stirring rod arranged at the bottom of the planetary gear. The planetary gears are respectively meshed with the sun gear and the internal gear ring. An upper driving member is arranged on the sieve box, and an upper driving gear located inside the sieve box is arranged at the output end of the upper driving member. An external gear ring meshed with the upper driving gear is arranged outside the internal gear ring.

[0011] By adopting the above technical solution, the output end of the upper driving member drives the upper driving gear to rotate, thereby driving the external gear ring and the internal gear ring to rotate together, so that the rotation of the internal gear ring can drive the planetary gear to rotate self and revolve around the sun gear, so as to increase the stirring range of the upper stirring rod at the bottom of the planetary gear. Thus, with the cooperation of the upper sieve assembly, the workpieces and waste materials can pass through the first sieve more smoothly, while the abrasives are discharged outside the sieve box through the abrasive feeding pipe.

[0012] Optionally, the lower stirring assembly includes a plurality of lower stirring shafts rotatably connected inside the sieve box, spiral blades arranged on the outer sides of the lower stirring shafts, linkage gears arranged on the lower stirring shafts and located outside the sieve box, and a lower driving member arranged outside the sieve box and used to drive one of the lower stirring shafts to rotate. The two linkage gears are meshed with each other. The lower stirring shafts and the spiral blades are both located between the upper sieve assembly and the lower sieve assembly.

[0013] By adopting the above technical solution, the output end of the lower driving member drives one of the lower stirring shafts to rotate. Since the spiral directions of the two spiral blades are opposite, the workpieces can be continuously pushed to a position close to the workpiece feeding pipe with the cooperation of the second sieve, and finally discharged outside the sieve box through the workpiece feeding pipe, while the waste materials pass through the second sieve and finally fall to the inner bottom of the sieve box.

[0014] Optionally, an air ventilation component is provided outside the sieve box. The air ventilation component includes an air pump disposed outside the sieve box, a main air delivery pipe disposed at the output end of the air pump, an air delivery branch pipe disposed at the end of the main air delivery pipe away from the air pump, and a communication ring rotatably sleeved outside the lower stirring shaft and communicating with the other end of the air delivery branch pipe. The lower stirring shaft is hollow, and a plurality of communication ports communicating with the air delivery branch pipe are formed at the position of the lower stirring shaft corresponding to the communication ring. The sizes of the plurality of communication ports are different. A workpiece blanking pipe is provided at the position of the sieve box corresponding to the lower sieve mesh assembly. A plurality of exhaust pipes inclined away from the workpiece blanking pipe are provided outside the lower stirring shaft. A blocking net is provided at the pipe orifice of the exhaust pipe. A plurality of exhaust holes are formed at the position of the sieve box away from the workpiece blanking pipe and corresponding to the lower sieve mesh assembly.

[0015] By adopting the above technical solution, the air pump extracts external air into the main air delivery pipe and delivers it to the two air delivery branch pipes respectively. Then the air is delivered to the communication ring. As the lower stirring shaft rotates continuously, the air delivery branch pipe can communicate with different communication ports at different times, so that the air in the air delivery branch pipe is delivered into the cavity in the lower stirring shaft through the communication ports and discharged through the exhaust pipes. Since the exhaust pipes are inclined away from the workpiece blanking pipe, the waste can be blown away from the position of the workpiece blanking pipe, making it difficult for the waste to be discharged through the workpiece blanking pipe.

[0016] Optionally, the workpiece blanking pipe and the lower driving member are located on the same side of the sieve box. A plurality of heating wires are provided on the inner wall of the main air delivery pipe to heat the air in the main air delivery pipe.

[0017] By adopting the above technical solution, the heating wires in the main air delivery pipe heat the gas therein. After these heated gases enter the sieve box, they can soften the waste to a certain extent, making it difficult to get stuck in the mesh holes of the second sieve, and these gases can also dry the moisture on the surface of the workpiece to a certain extent.

[0018] Optionally, a cover body covering the lower driving member is provided outside the sieve box. The cover body divides the main air delivery pipe into two parts and communicates with it. The heating wires are provided in the section of the main air delivery pipe communicating with the sieve box. A space for air to pass through is left between the cover body and the lower driving member.

[0019] By adopting the above technical solution, heat is generated when the lower driving member works. After the external air extracted by the air pump enters the cover body, the heat can be delivered to the section of the main air delivery pipe communicating with the sieve box through the air, so as to utilize the heat generated by the lower driving member.

[0020] Optionally, a plurality of pressure relief valves are provided on the cover body, and a one-way valve for the air in the cover body to flow into the sieve box unidirectionally is provided on the main air delivery pipe.

[0021] By adopting the above technical solution, when the air pressure in the gas distribution branch pipe increases, it means that it is difficult for the cover body to transport gas into the gas distribution branch pipe, which will cause the gas and heat in the cover body to be unable to be discharged. Therefore, when the gas pressure in the cover body reaches the set threshold value, the pressure relief valve will open, thereby relieving the pressure inside the cover body to discharge the pressure and heat in the cover body.

[0022] Optionally, rubber coatings are provided on the outer sides of the lower stirring shaft, the spiral blades and the exhaust pipe, and a plurality of hemispherical rubber protrusions are provided on the outer side of the rubber coating.

[0023] By adopting the above technical solution, the impact on the spiral blades and the lower stirring shaft when the workpiece falls onto them can be reduced, thereby playing a certain protective role for the lower stirring shaft and the spiral blades.

[0024] Optionally, a waste hopper is slidably arranged in the sieve box and below the lower sieve mesh assembly, and a handle is arranged on one side of the waste hopper.

[0025] By adopting the above technical solution, when the waste passes through the second sieve mesh, it can fall into the waste hopper. After the waste in the waste hopper accumulates to a certain amount, the waste hopper is horizontally pulled out through the handle, which is convenient for cleaning the waste in the waste hopper.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Pour the workpieces, abrasives, and wastes in the grinding tank into the sieve box together, so that the workpieces, abrasives, and wastes fall onto the upper sieve mesh assembly. Then, the upper stirring assembly stirs the materials on the upper sieve mesh assembly. The upper sieve mesh assembly screens the abrasives in the materials, so that the screened workpieces and wastes fall onto the lower sieve mesh assembly, and the abrasives are screened out of the sieve box. The lower stirring assembly stirs the materials on the lower sieve mesh assembly. The lower sieve mesh assembly screens the wastes in the materials, so that the screened wastes fall to the bottom of the sieve box, and the workpieces are screened out of the sieve box, thereby realizing the separation of abrasives, workpieces, and wastes; 2. The output end of the lower driving part drives one of the lower stirring shafts to rotate. Since the spiral directions of the two spiral blades are opposite, the workpieces can be continuously pushed towards the position close to the workpiece feeding pipe under the cooperation of the second sieve mesh, and finally discharged out of the sieve box through the workpiece feeding pipe, while the wastes pass through the second sieve mesh and finally fall to the inner bottom of the sieve box; 3. The heating wire in the main gas supply pipe heats the gas therein. After these heated gases enter the sieve box, they can soften the wastes to a certain extent, making it not easy to get stuck in the mesh holes of the second sieve mesh, and these gases can also dry the moisture on the surface of the workpieces to a certain extent.

Detailed implementation manners

[0029] The following further elaborates on this application Figure 1-6 in conjunction with the appended drawings.

[0030] The embodiment of this application discloses a vortex surface degumming method. Referring to Figure 1 and Figure 2 , the vortex surface degumming method includes the following steps: S1: Put the workpiece and the abrasive into the grinding tank of the vortex finishing machine 1 together, generate a vortex motion through the high-speed rotation of the rotating disk, make the workpiece and the abrasive fully rub against each other, separate the workpiece from the waste, and during the grinding process, take away the fine impurities generated by grinding through the circulating water flow.

[0031] S2: After grinding is completed, pour the workpieces, abrasives, and waste materials in the grinding tank onto the upper screen assembly 22 of the sieve box 21, and stir the materials on the upper screen assembly 22 through the upper stirring assembly 23. The upper screen assembly 22 screens the abrasives in the materials, causing the screened workpieces and waste materials to fall onto the lower screen assembly 24, and screening the abrasives outside the sieve box 21.

[0032] S3: The lower stirring assembly 25 stirs the materials on the lower screen assembly 24. The lower screen assembly 24 screens the abrasives in the materials, causing the screened waste materials to fall to the inner bottom of the sieve box 21, and screening the workpieces outside the sieve box 21.

[0033] The embodiment of the present application also discloses a vortex surface degumming device, including a vortex finishing machine 1 and a vibration separation mechanism 2. The vortex finishing machine 1 is used to process workpieces to separate waste materials from the surfaces of the workpieces. The vibration separation mechanism 2 is located diagonally below the vortex finishing machine 1, and the vibration separation mechanism 2 screens the workpieces processed by the vortex finishing machine 1.

[0034] The vibration separation mechanism 2 includes a sieve box 21, an upper screen assembly 22, an upper stirring assembly 23, a lower screen assembly 24, and a lower stirring assembly 25. The sieve box 21 is located diagonally below the vortex finishing machine 1. The sieve box 21 is integrally square. A feed hopper 211 is fixedly connected to the top of the sieve box 21. The feed hopper 211 is wider at the top and narrower at the bottom. The upper screen assembly 22 is installed in the upper middle part of the sieve box 21 to screen the abrasives in the materials and cause the screened workpieces and waste materials to fall onto the lower screen assembly 24. The upper stirring assembly 23 is installed in the sieve box 21 and is located above the upper screen assembly 22. The upper stirring assembly 23 stirs the materials on the upper screen assembly 22. The lower screen assembly 24 is installed in the lower middle part of the sieve box 21. The lower screen assembly 24 screens the workpieces in the materials and causes the waste materials to fall to the inner bottom of the sieve box 21. The lower stirring assembly 25 is installed in the sieve box 21. The lower stirring assembly 25 is located between the upper screen assembly 22 and the lower screen assembly 24. The lower stirring assembly 25 stirs the materials on the lower screen assembly 24.

[0035] Put the workpiece and abrasive into the grinding tank of the vortex finishing machine 1 together. Through the high-speed rotation of the rotating disk, a vortex motion is generated, enabling the workpiece and the abrasive to fully rub against each other, so that the waste on the surface of the workpiece is separated. During the grinding process, the fine impurities generated by grinding are carried away by the circulating water flow. After grinding is completed, the rotating disk is driven to flip by the driving structure inside the vortex finishing machine 1, so that the material discharge port of the rotating disk is aligned with the feed hopper 211 of the sieve box 21, thereby pouring the workpiece, abrasive, and waste in the grinding tank into the sieve box 21 together, causing the workpiece, abrasive, and waste to fall onto the upper sieve assembly 22. Then, the upper stirring assembly 23 stirs the materials on the upper sieve assembly 22. The upper sieve assembly 22 screens the abrasive in the materials, causing the screened workpiece and waste to fall onto the lower sieve assembly 24, and screening the abrasive outside the sieve box 21. The lower stirring assembly 25 stirs the materials on the lower sieve assembly 24. The lower sieve assembly 24 screens the waste in the materials, causing the screened waste to fall to the inner bottom of the sieve box 21, and screening the workpiece outside the sieve box 21, thereby realizing the separation of the abrasive, workpiece, and waste. Due to the setting of the upper stirring assembly 23, the upper stirring assembly 23 can more smoothly make the workpiece and waste pass through the upper sieve assembly 22 in cooperation with the upper sieve assembly 22. Due to the setting of the lower stirring assembly 25, the lower stirring assembly 25 can more smoothly make the waste pass through the lower sieve assembly 24 in cooperation with the lower sieve assembly 24, thus making the separation effect better.

[0036] It should be noted that the vortex finishing machine 1 is a prior art, and its structure and principle will not be elaborated here. The upper sieve assembly 22 includes a first sieve and a first linear vibration motor. The first sieve is horizontally slidably connected to the upper middle part of the sieve box 21. Both ends of the first sieve penetrate and extend outside the sieve box 21. The first linear vibration motor is installed at the bottom of the first sieve and drives the first sieve to vibrate horizontally. And upper blocking plates are vertically fixed at both ends of the first sieve. The upper blocking plates are used to prevent the materials on the first sieve from moving to the sliding part between the first sieve and the sieve box 21. The lower sieve assembly 24 includes a second sieve and a second linear vibration motor. The second sieve is horizontally slidably connected to the lower middle part of the sieve box 21. Both ends of the second sieve penetrate and extend outside the sieve box 21. The second linear vibration motor is installed at the bottom of the second sieve and drives the second sieve to vibrate horizontally. And lower blocking plates are vertically fixed at both ends of the second sieve. The lower blocking plates are used to prevent the materials on the second sieve from moving to the sliding part between the second sieve and the sieve box 21.

[0037] In addition, an abrasive feeding pipe 212 is fixedly communicated with the outside of the sieve box 21 corresponding to the position of the first sieve, and a workpiece feeding pipe 213 is fixedly communicated with the outside of the sieve box 21 corresponding to the position of the second sieve. The abrasive feeding pipe 212 and the workpiece feeding pipe 213 are respectively located on opposite sides outside the sieve box 21.

[0038] Refer to Figure 2 andFigure 3 , preferably, the upper stirring assembly 23 includes a sun gear 231, an internal gear ring 232, a plurality of annular sliders 233, planetary gears 234 and an upper stirring rod 235. The sun gear 231 is fixedly connected to the center position of the inner top of the sieve box 21. An opening for the material to pass through is formed in the middle of the sun gear 231. The internal gear ring 232 is rotatably connected to the inner top of the sieve box 21. The internal gear ring 232 is located outside the sun gear 231. An annular chute is formed in the inner top of the sieve box 21. The annular chute is located between the sun gear 231 and the internal gear ring 232. A plurality of annular sliders 233 are all slidably connected in the annular chute. In this embodiment, the cross-sections of the annular chute and the annular sliders 233 are both T-shaped, and the number of the annular sliders 233 is three. The planetary gears 234 are rotatably connected to the bottoms of the annular sliders 233, and the planetary gears 234 are respectively meshed with the sun gear 231 and the internal gear ring 232. The upper stirring rod 235 is vertically fixed to the bottom of the planetary gear 234. A upper driving member 236 is fixed to the top of the sieve box 21. In this embodiment, the upper driving member 236 is a servo motor. An upper driving gear 237 is fixed to the output end of the upper driving member 236. The upper driving gear 237 is located inside the sieve box 21. An external gear ring 238 is fixed to the outside of the internal gear ring 232, and the upper driving gear 237 is meshed with the external gear ring 238.

[0039] When the abrasive, the workpiece and the waste fall onto the upper sieve assembly 22 together, the output end of the upper driving member 236 drives the upper driving gear 237 to rotate, thereby driving the external gear ring 238 and the internal gear ring 232 to rotate together. Since the planetary gears 234 are respectively meshed with the sun gear 231 and the internal gear ring 232, the annular sliders 233 are all slidably connected in the annular chute, and the planetary gears 234 are rotatably connected to the bottoms of the annular sliders 233, the rotation of the internal gear ring 232 can drive the planetary gears 234 to rotate self and revolve around the sun gear 231, so as to increase the stirring range of the upper stirring rod 235 at the bottom of the planetary gears 234. Since the size of the abrasive is larger than that of the workpiece, and the size of the waste is smaller than that of the workpiece, the workpiece and the waste can pass through the first sieve more smoothly with the cooperation of the upper sieve assembly 22, while the abrasive is discharged out of the sieve box 21 through the abrasive feeding pipe 212.

[0040] Refer to Figure 3, Further, the lower stirring assembly 25 includes a lower stirring shaft 251, a spiral blade 252, a linkage gear 253, and a lower driving member 254. There are two lower stirring shafts 251, and both of the two lower stirring shafts 251 are horizontally rotatably connected in the sieve box 21, and the lower stirring shafts 251 are located between the upper sieve assembly 22 and the lower sieve assembly 24. The length direction of the lower stirring shaft 251 is perpendicular to the vibration direction of the second sieve. The spiral blade 252 is fixedly connected to the outside of the lower stirring shaft 251. The lower driving member 254 is fixedly installed outside the sieve box 21, and the output end of the lower driving member 254 is fixedly connected to one of the lower stirring shafts 251. The linkage gear 253 is fixedly arranged on the outside of the lower stirring shaft 251. The linkage gear 253 is located outside the sieve box 21, and the two linkage gears 253 are meshed with each other.

[0041] When the workpieces and waste materials fall onto the lower sieve assembly 24 together, the output end of the lower driving member 254 drives one of the lower stirring shafts 251 to rotate. Since the two linkage gears 253 are meshed with each other, the rotation directions of the two lower stirring shafts 251 are opposite. And because the spiral directions of the two spiral blades 252 are opposite, thus, with the cooperation of the second sieve, the workpieces can be continuously pushed to the position close to the workpiece blanking pipe 213, and finally discharged outside the sieve box 21 through the workpiece blanking pipe 213, while the waste materials pass through the second sieve and finally fall to the inner bottom of the sieve box 21.

[0042] Refer to Figure 4 and Figure 5 , Preferably, an air ventilation assembly 26 is installed outside the sieve box 21. The air ventilation assembly 26 includes an air pump 261, an air delivery main pipe 262, air delivery branch pipes 263, and a communication ring 264. The air pump 261 is fixedly installed outside the sieve box 21. The air delivery main pipe 262 is fixedly communicated with the output end of the air pump 261. The air delivery branch pipes 263 are fixedly communicated with one end of the air delivery main pipe 262 away from the air pump 261. There are two air delivery branch pipes 263, and the position of each air delivery branch pipe 263 corresponds to the position of each lower stirring shaft 251. The communication ring 264 is fixedly communicated with one end of the air delivery branch pipe 263 away from the air delivery main pipe 262. The communication ring 264 is rotatably sleeved on the outside of the lower stirring shaft 251. The lower stirring shaft 251 is hollow, and four communication ports 2511 communicated with the air delivery branch pipes 263 are opened on the outside of the lower stirring shaft 251 corresponding to the position of the communication ring 264. The four communication ports 2511 are circumferentially arranged on the outside of the lower stirring shaft 251, and the four communication ports 2511 have two sizes and are arranged in sequence of size.

[0043] Refer to Figure 6 , A plurality of exhaust pipes 2512 are fixedly communicated with the outside of the lower stirring shaft 251. The exhaust pipes 2512 are inclined towards the direction away from the workpiece blanking pipe 213. A blocking net is installed at the pipe orifice of the exhaust pipes 2512. A plurality of exhaust holes 214 are opened in the sieve box 21 at the position away from the workpiece blanking pipe 213 and corresponding to the lower sieve assembly 24.

[0044] Referring to Figure 4 and Figure 5 The air pump 261 extracts external air into the air delivery main pipe 262 and delivers it to two air delivery branch pipes 263 respectively. Then the air is delivered to the connection ring 264. As the lower stirring shaft 251 rotates continuously, the air delivery branch pipe 263 can communicate with the connection ports 2511 at different positions at different times. Thus, the air in the air delivery branch pipe 263 is delivered into the cavity in the lower stirring shaft 251 through the connection port 2511 and discharged through the exhaust pipe 2512. Since the exhaust pipe 2512 is inclined away from the workpiece blanking pipe 213, the waste can be blown away from the position of the workpiece blanking pipe 213, making it difficult for the waste to be discharged through the workpiece blanking pipe 213. In addition, when the connection port 2511 at the lower stirring shaft 251 rotates to be not in communication with the air delivery branch pipe 263, a certain degree of high-pressure gas will be generated in the air delivery branch pipe 263 and the air delivery main pipe 262. When the next connection port 2511 on the lower stirring shaft 251 rotates to be in communication with the air delivery branch pipe 263, these high-pressure gases can be ejected, which can not only further blow the waste away from the position of the workpiece blanking pipe 213, but also apply a thrust to the waste blocked in the mesh holes of the second sieve, reducing the phenomenon of waste blockage on the second sieve.

[0045] Preferably, the workpiece blanking pipe 213 and the lower driving member 254 are located on the same side of the sieve box 21. A cover body 215 is fixedly installed outside the sieve box 21. The cover body 215 covers the lower driving member 254 inside. The cover body 215 divides the air delivery main pipe 262 into two parts. The upper and lower ends of the cover body 215 are respectively communicated with the two sections of the air delivery main pipe 262. A plurality of heating wires are installed on the inner wall of the air delivery main pipe 262, and the heating wires are installed in the section of the air delivery main pipe 262 communicated with the sieve box 21. A space for air to pass through is left between the cover body 215 and the lower driving member 254.

[0046] When the lower driving member 254 works, heat will be generated. After the external air extracted by the air pump 261 enters the inside of the cover body 215, these heats can be delivered to the section of the air delivery main pipe 262 communicated with the sieve box 21 through the air, thus making use of the heat generated by the lower driving member 254. Then the heating wires in this section of the air delivery main pipe 262 further heat the gas inside, making the temperature of the gas further increase. After these heated gases enter the inside of the sieve box 21, they can soften the waste to a certain extent, making it not easy to get stuck in the mesh holes of the second sieve, and these gases can also dry the moisture on the surface of the workpiece to a certain extent.

[0047] It should be noted that rubber coatings are provided on the outer sides of the lower stirring shaft 251, the spiral blades 252, and the exhaust pipe 2512, and a plurality of hemispherical rubber protrusions 2513 are provided on the outer sides of the rubber coatings. The rubber coatings and the hemispherical rubber protrusions 2513 can reduce the impact on the spiral blades 252 and the lower stirring shaft 251 when the workpiece falls onto them, thereby playing a certain protective role for the lower stirring shaft 251 and the spiral blades 252.

[0048] Furthermore, pressure relief valves 2151 are installed on both the left and right sides of the cover body 215, and a check valve 2621 is installed on the air delivery main pipe 262. The check valve 2621 only allows the air in the cover body 215 to flow into the sieve box 21 unidirectionally. Since the gas in the air delivery main pipe 262 connected to the sieve box 21 is heated by the heating wire and has a relatively high temperature, when the air pressure in the air delivery branch pipe 263 increases, the gas will not flow back into the cover body 215, so the heat will not be brought back to the cover body 215. In addition, when the air pressure in the air delivery branch pipe 263 increases, it means that it is difficult for the cover body 215 to deliver gas into the air delivery branch pipe 263, which will cause the gas and heat in the cover body 215 to be unable to be discharged. Therefore, when the gas pressure in the cover body 215 reaches the set threshold value, the pressure relief valve 2151 will open to relieve the pressure inside the cover body 215 and discharge the pressure and heat in the cover body 215.

[0049] Refer to Figure 6 , preferably, a waste hopper 216 is slidably installed in the sieve box 21 and below the lower sieve mesh assembly 24. The waste hopper 216 is used to hold the waste falling from the lower sieve mesh assembly 24, and a handle is installed on one side of the waste hopper 216. When the waste passes through the second sieve mesh, it can fall into the waste hopper 216. After the waste in the waste hopper 216 accumulates to a certain amount, the waste hopper 216 is horizontally pulled out through the handle to facilitate the cleaning of the waste in the waste hopper 216.

[0050] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
