Description

Technical Field

[0001] The present invention relates to the technical field of medical waste treatment equipment, and particularly relates to a treatment device and a treatment method for medical waste controlled injection bottles. Background Art

[0002] The injection bottle 400 in production includes a glass bottle body 401, a rubber stopper 403, and an aluminum ring 402 for fixing the rubber stopper 403 on the mouth of the glass bottle body 401. After the injection bottle 400 in production is used, it becomes medical waste. Since the injection bottle 400 in production includes the glass bottle body 401, the rubber stopper 403, and the aluminum ring 402, these three parts need to be separated during treatment.

[0003] In the prior art, Chinese patent document CN109909047A, publication (announcement) date: June 21, 2019, discloses a sorting method for a medical waste glass bottle sorting line by our company, which includes a jaw crusher, a drum sieve, a glass bottle screening machine, and a pneumatic separator. The glass bottle is transported to the jaw crusher by a first belt conveyor for primary crushing to form a ternary mixture composed of glass slag, rubber, and aluminum sheets. The ternary mixture discharged from the jaw crusher is transported to the drum sieve by a second belt conveyor. The glass slag in the ternary mixture screened by the drum sieve is discharged into a glass collection box, and the rubber stopper screened by the drum sieve is discharged into the glass bottle screening machine. The rubber stopper is rubbed, crushed, and screened by the glass bottle screening machine. The remaining glass slag screened by the glass bottle screening machine is sent to the glass collection box, and the screened rubber is sent to the pneumatic separator for sorting of the rubber and aluminum sheets. Its characteristics are: it can further crush and screen the ternary mixture of glass bottles that cannot be completely separated by the jaw crusher; its disadvantages are: in this solution, the elasticity of the rubber stopper itself is used, and under the action of the friction plate, the rubber stopper bounces into the rubber stopper discharge pipe for discharge. In application, the material in the pipe shell can only be a thin layer. If there is too much material, due to the blockage of the upper layer of material, the rubber stopper cannot smoothly bounce into the rubber stopper discharge pipe for discharge, so the production efficiency is very low.

[0004] In addition, Chinese Patent Document CN118384968A, publication (announcement) date: July 26, 2024, discloses a fully automatic medical glass bottle recycling and sorting device and method, including a base, a crushing component and a screening component. A driving component is installed above the base, and the driving component is the power source of the crushing component. The crushing component can drive the screening component to move. The base includes a hopper component, and an eddy current sorting component is arranged above the hopper component. The eddy current sorting component is arranged between the screening component and the hopper component; the screening component includes a crank, and the two ends of the crank are eccentrically and fixedly connected to the cutting roller. The crank is rotationally connected to a rotating rod, and the lower end of the rotating rod is rotationally connected to a crushing screen. The crushing screen is rotationally connected to the inner wall of the feed hopper. The crushing screen swings periodically driven by the cutting roller, and the glass fragments are secondarily crushed by the crushing screen. Its characteristics are: This solution solves the technical problem that it is difficult to separate the rubber stoppers and aluminum caps installed on the bottle heads after the medical glass bottles are crushed, and additional processes are required to separate the aluminum caps and rubber stoppers; its disadvantage is that due to extrusion crushing and cutting, the aluminum ring 402 and the rubber stopper 403 will be combined more tightly, and the aluminum ring 402 and the rubber stopper 403 cannot be completely separated, resulting in a poor separation effect of the aluminum ring 402 and the rubber stopper 403.

The third discharge hopper is used to convey the combination of the rubber stopper and the aluminum ring to the first conveyor belt device of the rubber stopper-aluminum ring separation unit.

[0015] A treatment method for medical waste controlled injection bottles adopts the above-mentioned medical waste controlled injection bottle treatment device. The treatment method includes the following steps: S1. The glass bottle body of the controlled injection bottle is crushed by the crushing unit to separate the combination of the rubber stopper and the aluminum ring from the glass bottle body. S2. The combination of the rubber stopper and the aluminum ring is extruded and deformed by the screening unit to make the combination of the rubber stopper and the aluminum ring tend to be flat. Then, the fragments of the glass bottle body are screened out. The combination of the rubber stopper and the aluminum ring is conveyed to the first conveyor belt device of the rubber stopper-aluminum ring separation unit through the screening unit. S3. The combination of the rubber stopper and the aluminum ring is conveyed to the lower part of the pressing and rubbing device through the first conveyor belt device. Driven by the first reduction motor, the pressing and rubbing plate swings circumferentially with the output shaft of the first reduction motor as the center, presses and rubs the combination of the rubber stopper and the aluminum ring under the pressing and rubbing plate, and rubs the rubber stopper out of the aluminum ring to separate the rubber stopper from the aluminum ring.

[0016] Compared with the prior art, the present invention has the following technical effects: 1. The crushing unit of the present invention is used to crush the glass bottle body of the controlled injection bottle so that the combination of the rubber stopper and the aluminum ring is separated from the glass bottle body. The screening unit is used to squeeze and deform the combination of the rubber stopper and the aluminum ring so that the combination of the rubber stopper and the aluminum ring tends to be flat, and then the fragments of the glass bottle body are screened out. The combination of the rubber stopper and the aluminum ring is guided to the first conveyor belt device of the rubber stopper and aluminum ring separation unit through the screening unit. The combination of the rubber stopper and the aluminum ring moves downstream along with the first conveyor belt device and thus enters under the pressing and rubbing plate of the pressing and rubbing device. Since the pressing and rubbing plate is connected to the output shaft of the first reduction motor through the first crank arm, the pressing and rubbing plate can swing by the rotation of the output shaft of the first reduction motor. Moreover, the pressing and rubbing plate is also rotatably connected to the first frame through a plurality of second crank arms, so that the pressing and rubbing plate swings circumferentially with the output shaft of the first reduction motor as the fixed center. Since there is a certain distance between the first conveyor belt device and the pressing and rubbing plate, and this distance is less than the height of the combination of the rubber stopper and the aluminum ring, the rubber stopper can be squeezed, so that the friction between the rubber stopper and the first conveyor belt device or between the rubber stopper and the pressing and rubbing plate increases. When the pressing and rubbing plate swings, the rubber stopper is taken out of the aluminum ring, so that the rubber stopper and the aluminum ring are separated, and the separation efficiency and separation effect of the aluminum ring and the rubber stopper are higher and better.

[0017] 2. The rubber stopper and aluminum ring separation unit of the present invention further includes a rubber stopper and aluminum ring separation device to further separate the separated rubber stopper and aluminum ring.

[0018] 3. Through the limit baffle on the second conveyor belt, the controlled injection bottles in the first feed hopper are sequentially pushed out. Since the limit baffles are evenly arranged and the distance between adjacent limit baffles is slightly larger than the diameter of the controlled injection bottle, the controlled injection bottles are neatly arranged on the second conveyor belt. In addition, since the maximum distance between the extrusion groove and the second conveyor belt is less than the diameter of the controlled injection bottle and is equal to slightly less than the diameter of the combination of the rubber stopper and the aluminum ring, as shown in the enlarged view in the figure, in this process, the glass bottle body of the controlled injection bottle can be squeezed and broken, while the combination of the rubber stopper and the aluminum ring will not be greatly deformed.

[0019] 4. The combination of the rubber stopper and the aluminum ring is extruded and deformed by two crushing rollers in the present invention, and its functions have at least the following two points: First, since the rubber stopper has good elasticity, in this process, the aluminum ring is extruded into a uniform thickness, which is convenient for entering the rubber stopper-aluminum ring separation unit. And after extrusion, due to the existence of the gap, the rubber stopper returns to its original height. Second, it can further extrude and crush the glass bottle body.

Specific embodiments

[0034] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0035] Embodiment 1: See Figure 1-12, a medical waste controlled injection bottle processing device, including a crushing unit 100, a screening unit 200, and a rubber stopper-aluminum ring separation unit 300. The rubber stopper-aluminum ring separation unit 300 includes a first frame 301, a first conveyor belt device 310, and a pressing and rubbing device 320. The first conveyor belt device 310 and the pressing and rubbing device 320 are both installed on the first frame 301, and the pressing and rubbing device 320 is located above the first conveyor belt device 310. The pressing and rubbing device 320 includes a first reduction motor 321 and a pressing and rubbing plate 323. The first reduction motor 321 is fixedly installed on the first frame 301. The output shaft of the first reduction motor 321 faces the first conveyor belt device 310. A first crank arm 322 is installed on the output shaft of the first reduction motor 321. A plurality of second crank arms 325 are also rotatably installed on the first frame 301. A plurality of connecting sleeves 324 are fixedly provided on the upper side of the pressing and rubbing plate 323. The protruding shafts 3251 at the lower ends of the first crank arm 322 and the second crank arms 325 are respectively rotatably connected with the corresponding connecting sleeves 324 in a rotating fit manner. The first conveyor belt device 310 is spaced from the pressing and rubbing plate 323 by a certain distance.

[0036] The crushing unit 100 is used to crush the glass bottle body 401 of the controlled injection bottle 400 so that the combination of the rubber stopper 403 and the aluminum ring 402 is separated from the glass bottle body 401. The screening unit 200 is used to squeeze and deform the combination of the rubber stopper 403 and the aluminum ring 402 so that the combination of the rubber stopper 403 and the aluminum ring 402 tends to be flat. Then, the fragments of the glass bottle body 401 are screened out. The combination of the rubber stopper 403 and the aluminum ring 402 is sent to the first conveyor belt device 310 of the rubber stopper-aluminum ring separation unit 300 through the screening unit 200. The combination of the rubber stopper 403 and the aluminum ring 402 moves downstream along with the first conveyor belt device 310 and thus enters under the pressing and rubbing plate 323 of the pressing and rubbing device 320. Since the pressing and rubbing plate 323 is connected to the output shaft of the first reduction motor 321 through the first crank arm 322, the pressing and rubbing plate 323 can swing due to the rotation of the output shaft of the first reduction motor 321. And the pressing and rubbing plate 323 is also rotatably connected to the first frame 301 through a plurality of second crank arms 325, so that the pressing and rubbing plate 323 swings in a circle centered on the output shaft of the first reduction motor 321. Since the first conveyor belt device 310 is spaced from the pressing and rubbing plate 323 by a certain distance, and this distance is less than the height of the combination of the rubber stopper 403 and the aluminum ring 402, the rubber stopper 403 can be squeezed, so that the friction between the rubber stopper 403 and the first conveyor belt device 310 or between the rubber stopper 403 and the pressing and rubbing plate 323 increases. When the pressing and rubbing plate 323 swings, the rubber stopper 403 is taken out from the aluminum ring 402, thus separating the rubber stopper 403 from the aluminum ring 402.

[0037] In this embodiment, in order to increase the friction of the pressing and rubbing plate 323, a structure for increasing the friction is provided at the bottom of the pressing and rubbing plate 323, such as a knurling structure similar to that on a file, or a rubber layer is fixedly provided at the bottom of the pressing and rubbing plate 323.

[0038] In this embodiment, referring to Figure 9 , 10 , both the first toggle arm 322 and the second toggle arm 325 are in a "Z" - shaped structure, and the center distances between the upper and lower ends of the first toggle arm 322 and the second toggle arm 325 extending out of the shaft 3251 are the same. Referring to Figure 10 , the shaft 3251 extending out of the upper end of the first toggle arm 322 is a sleeve structure. The shaft 3251 of the sleeve structure has an interference fit with the output shaft of the first reduction motor 321 and is limited by a key pair.

[0039] Furthermore, referring to Figure 10 , 11 , a limiting portion 3252 is provided at the lower end of the shaft 3251. The diameter of the limiting portion 3252 is larger than the diameter of the shaft 3251. The inner ring of the first bearing 326 is slidably mounted on the shaft 3251, and the outer ring of the first bearing 326 is fixedly mounted at the upper end inside the connecting sleeve 324. An elastic body 327 is installed inside the connecting sleeve 324 between the limiting portion 3252 and the pressing and rubbing plate 323. Through the above - mentioned structure, the pressing and rubbing plate 323 can elastically apply downward pressure. In this embodiment, referring to Figure 11 , the inner ring of the first bearing 326 can be slidably connected with the shaft 3251 through a spline pair structure. Since the first bearing 326 is installed inside the connecting sleeve 324 by a snap ring or interference fit, the shaft 3251 will not come out of the connecting sleeve 324.

[0040] In this embodiment, the elastic body 327 can be a spring or an elastic rubber column.

[0041] Furthermore, referring to Figure 9 , a feed slope 3231 is provided on the lower side of the feed end of the pressing and rubbing plate 323, so that the pressing and rubbing plate 323 has a larger opening in the upstream direction of the first conveyor belt device 310, facilitating the combination of the rubber plug 403 and the aluminum ring 402 to enter below the pressing and rubbing plate 323.

[0042] In this embodiment, referring to Figure 9 , 10, on the first rack 301, a support plate 370 is fixedly provided on the upper side of the first conveyor belt device 310. The first reduction motor 321 is fixedly installed on the support plate 370. On the support plate 370, a first bearing block 328 is installed at a position corresponding to the upper end shaft of the second crank arm 325. After the upper end shaft of the second crank arm 325 passes through the support plate 370, the second crank arm 325 is rotatably connected to the first bearing block 328. By installing the support plate 370 on the first rack 301, it is convenient to install the first reduction motor 321 and the second crank arm 325.

[0043] Specifically, the first rack 301 is of a frame structure. The support plate 370 is welded inside the first rack 301. The first bearing block 328 adopts a UCF type bearing block.

[0044] See Figure 9 , 10 , the first conveyor belt device 310 includes a first driving roller 311, a first driven roller 312, a first conveyor belt 313 and a second reduction motor 314. The first driving roller 311 and the first driven roller 312 are respectively rotatably installed on the first rack 301 through bearing blocks. The first conveyor belt 313 is tensioned and sleeved on the first driving roller 311 and the first driven roller 312. The second reduction motor 314 is installed on the first rack 301 or the central axis of the first driving roller 311. The output shaft of the second reduction motor 314 is in transmission connection with the first driving roller 311 to drive the first driving roller 311 to rotate; a first support plate 360 is fixedly provided on the first rack 301. The first support plate 360 supports the lower side of the upper layer of the first conveyor belt 313. The second reduction motor 314 is used to drive the first driving roller 311 to rotate, thereby driving the first conveyor belt 313 to rotate. The first support plate 360 is used to support the upper layer of the first conveyor belt 313, so that the upper layer of the first conveyor belt 313 has stable support, which is convenient for the pressing and rubbing plate 323 to press and rub the combination of the rubber plug 403 and the aluminum ring 402 on the first conveyor belt 313.

[0045] In this embodiment, in order to improve the friction of the first conveyor belt 313, the first conveyor belt 313 adopts a rubber conveyor belt with patterns.

[0046] During production, the first conveyor belt 313 continuously rotates driven by the second reduction motor 314.

[0047] Embodiment 2: On the basis of Embodiment 1, see Figure 9 , 10 , the rubber plug and aluminum ring separation unit 300 further includes a rubber plug and aluminum ring separation device 330 to further separate the separated rubber plug 403 and aluminum ring 402.

[0048] Specifically, the rubber stopper and aluminum ring separation device 330 includes a second driving roller 331, a multi-stage magnetic roller 332, a third conveyor belt 333, and a third reduction motor 334. The second driving roller 331 and the multi-stage magnetic roller 332 are respectively rotatably mounted on the first frame 301 through bearing seats. The third conveyor belt 333 is sleeved on the second driving roller 331 and the multi-stage magnetic roller 332, and the third conveyor belt 333 is located below the downstream end of the first conveyor belt device 310. The third reduction motor 334 is mounted on the central axis of the first frame 301 or the first driving roller 311, and the output shaft of the third reduction motor 334 is in transmission connection with the second driving roller 331 to drive the second driving roller 331 to rotate. A fourth discharge hopper 350 is provided below the downstream end of the third conveyor belt 333 on the first frame 301, and a partition plate 340 is installed in the fourth discharge hopper 350. When the multi-stage magnetic roller 332 rotates, an alternating magnetic field is generated. When the aluminum ring 402 passes through the magnetic field, eddy currents are generated in the aluminum ring 402. The eddy currents themselves generate an alternating magnetic field, which is opposite to the magnetic field direction of the multi-stage magnetic roller 332. The two magnetic fields interact to generate an eddy current force, that is, a repulsive force is generated on the aluminum ring 402, separating the aluminum ring 402 and the rubber stopper 403.

[0049] See Figure 9 , a partition plate 340 is installed in the fourth discharge hopper 350. The partition plate 340 divides the fourth discharge hopper 350 into two discharge channels. During operation, the aluminum ring 402 passes through the channel far from the multi-stage magnetic roller 332 due to the repulsive force, while no magnetic field is generated in the rubber stopper 403 and it will not be repelled, so it falls into the channel close to the multi-stage magnetic roller 332.

The controlled injection bottles 400 in the first feed hopper 110 are sequentially pushed out through the limit baffles 124 on the second conveyor belt 123, and since the limit baffles 124 are evenly arranged and the spacing between adjacent limit baffles 124 is slightly larger than the diameter of the controlled injection bottle 400, the controlled injection bottle 400 is neatly arranged on the second conveyor belt 123. In addition, since the maximum distance between the extrusion groove 131 and the second conveyor belt 123 is smaller than the diameter of the controlled injection bottle 400 and is equal to slightly smaller than the diameter of the combination of the rubber plug 403 and the aluminum ring 402, see Figure 2 As shown in the enlarged view, during this process, the glass bottle body 401 of the controlled injection bottle 400 can be squeezed and broken, while the combination of the rubber plug 403 and the aluminum ring 402 will not be greatly deformed.

[0051] In order to facilitate installation of the limit baffle 124 on the second conveyor belt 123 and to provide an extrusion plane with sufficient hardness, the second conveyor belt 123 is made of a steel conveyor belt. The limit baffle 124 is laser welded on the steel conveyor belt.

[0052] Specifically, see Figure 2 , 3, 4. The second conveyor belt device 120 includes a third driving roller 121, a second driven roller 122, and a second conveyor belt 123.

Through the above structure, by one fourth reduction motor 150, the extrusion roller 130 is driven and then the second driven roller 122 rotates, and referring to Figure 2 , the extrusion roller 130 rotates counterclockwise. Through the reversing of the reversing gear and synchronous pulley group 128, the upper layer of the second conveyor belt 123 moves to the right.

[0053] In this embodiment, the first synchronous pulley 151 can be a synchronous pulley and a sprocket, the double-row synchronous pulley 133 can also be a synchronous pulley and a sprocket, the reversing gear and synchronous pulley group 128 is a combination of a reversing gear on one side and a synchronous pulley on the other side. The reversing gear is fixedly connected and coaxial with the synchronous pulley. The synchronous pulley in the reversing gear and synchronous pulley group 128 can also be a synchronous pulley and a sprocket. Correspondingly, the first synchronous belt or chain 152 is a synchronous belt or a chain, and the second synchronous belt or chain 129 is a synchronous belt or a chain.

[0054] Specifically, referring to Figure 2 , on the two side walls of the first feed hopper 110 on the side close to the extrusion roller 130, trough-shaped seats 111 are respectively welded. The opposite sides of the trough-shaped seats 111 respectively have longitudinal sliding grooves 112. The insertion plate 113 is inserted into the sliding grooves 112 of the two side trough-shaped seats 111. A limit screw 114 is rotatably connected to the outside of the trough-shaped seat 111, and the limit screw 114 abuts against the insertion plate 113 to limit the insertion plate 113.

[0055] Embodiment 4: On the basis of Embodiment 1 or Embodiment 2 or Embodiment 3, referring toFigure 5 , 6 7. The screening unit 200 includes a third frame 201, a crushing roller 210, a fifth reduction motor 250 and a vibrating screen 220. The two crushing rollers 210 are rotatably mounted on the third frame 201 through fourth bearing seats 214 respectively. The central axes of the two crushing rollers 210 are located on the same horizontal plane. There is a certain gap 213 between the roller surfaces of the two crushing rollers 210. Gears 216 are respectively installed at one end of the two crushing rollers 210. The two gears 216 are meshed. A driven wheel 215 is installed at one end of one of the crushing rollers 210. The fifth reduction motor 250 is installed on the third frame 201. A driving wheel 251 is installed on the output shaft of the fifth reduction motor 250. The driving wheel 25 1 is connected to the driven wheel 215 through a transmission belt and a chain 252. The third frame 201 is provided with a feed port 202 above the two crushing rollers 210. The lower end of the first discharge hopper 140 passes through the feed port 202 and extends to above the two crushing rollers 210. The vibrating screen 220 is obliquely installed below the two crushing rollers 210. The third frame 201 is provided with a second discharge hopper 230 below the vibrating screen 220. The third frame 201 is provided with a third discharge hopper 240 below the lowest end of the vibrating screen 220. The third discharge hopper 240 is used to guide the combination of the rubber plug 403 and the aluminum ring 402 to the first conveyor belt device 310 of the rubber plug aluminum ring separation unit 300. The combination of the rubber plug 403 and the aluminum ring 402 is squeezed and deformed by two crushing rollers 210, which has at least the following two functions: first, since the rubber plug 403 has good elasticity, the aluminum ring 402 is squeezed into a uniform thickness during this process, which is convenient for entering the rubber plug and aluminum ring separation unit 300, and after squeezing, the rubber plug 403 returns to its original height due to the existence of the gap 213; second, the glass bottle body 401 can be further squeezed and crushed.

[0056] Specifically, in order to increase the friction force of the crushing roller 210, the roller surface of the crushing roller 210 is processed with knurling or axial grooves.

[0057] Further, see Figure 8 A plurality of annular grooves 211 and annular platforms 212 are respectively arranged on the two crushing rollers 210. The annular platform 212 of the crushing roller 210 on one side extends into the annular groove 211 of the crushing roller 210 on the other side. Through the above structure, the glass bottle body 401 is limited to prevent the fragments of the glass bottle body 401 from slipping axially on the crushing roller 210.

[0058] In this embodiment, the vibrating screen 220 includes a screen body 221, which has a trough-shaped structure with an open lower side. The bottom surface of the screen body 221 is provided with screen holes 222. Two spring seats 203 are welded to both sides of the screen body 221 and on both sides of the third frame 201 respectively.

A vibrating motor 224 is installed at the bottom of the upstream end of the screen body 221.

[0059] Embodiment 5: Based on Embodiment 1 or Embodiment 2 or Embodiment 3 or Embodiment 4, refer to Figures 1 to 10 , combined with Figure 12 , a method for treating medical waste controlled injection vials, which adopts a medical waste controlled injection vial treatment device. The treatment method includes the following steps: S1. The glass bottle body 401 of the controlled injection vial 400 is broken by the crushing unit 100 so that the combination of the rubber stopper 403 and the aluminum ring 402 is separated from the glass bottle body 401.

[0060] Specifically, through the limit baffle 124 on the second conveyor belt 123, the controlled injection vials 400 in the first feed hopper 110 are sequentially pushed out. The limit baffles 124 are evenly arranged, and the distance between adjacent limit baffles 124 is slightly larger than the diameter of the controlled injection vial 400. Therefore, the controlled injection vials 400 are neatly arranged on the second conveyor belt 123. The maximum distance between the extrusion groove 131 and the second conveyor belt 123 is less than the diameter of the controlled injection vial 400 and is equal to slightly less than the diameter of the combination of the rubber stopper 403 and the aluminum ring 402. Refer to the enlarged view in Figure 2 . In this process, the glass bottle body 401 of the controlled injection vial 400 is squeezed and broken, while the combination of the rubber stopper 403 and the aluminum ring 402 will not be greatly deformed.

[0061] S2. The combination of the rubber stopper 403 and the aluminum ring 402 is squeezed and deformed by the screening unit 200 so that the combination of the rubber stopper 403 and the aluminum ring 402 tends to be flat. Then, the fragments of the glass bottle body 401 are screened out. The combination of the rubber stopper 403 and the aluminum ring 402 is sent to the first conveyor belt device 310 of the rubber stopper-aluminum ring separation unit 300 through the screening unit 200.

[0062] Specifically, the combination of the rubber stopper 403 and the aluminum ring 402 is extruded and deformed by two crushing rollers 210. Since the rubber stopper 403 has good elasticity, during this process, the aluminum ring 402 is extruded into a uniform thickness, which is convenient for entering the rubber stopper-aluminum ring separation unit 300. And after extrusion, due to the existence of the gap 213, the rubber stopper 403 returns to its original height. In addition, the glass bottle body 401 can be further crushed into small pieces. The small glass pieces and the combination of the rubber stopper 403 and the aluminum ring 402 fall onto the lower vibrating screen 220. The small glass pieces are screened out by the vibrating screen 220 due to their smaller volume and finally discharged from the lower second discharge hopper 230. While the combination of the rubber stopper 403 and the aluminum ring 402 with a larger area after extrusion falls from the lower end of the vibrating screen 220 to the third discharge hopper 240 and is then conveyed to the first conveyor belt device 310 of the rubber stopper-aluminum ring separation unit 300.

[0063] S3. The combination of the rubber stopper 403 and the aluminum ring 402 is conveyed to the lower part of the rubbing device 320 through the first conveyor belt device 310. The rubbing plate 323 swings in a circular motion centered on the output shaft of the first reduction motor 321 driven by the first reduction motor 321, and rubs the combination of the rubber stopper 403 and the aluminum ring 402 below the rubbing plate 323 to rub the rubber stopper 403 out of the aluminum ring 402 to separate the rubber stopper 403 and the aluminum ring 402.

[0064] Specifically, the combination of the rubber stopper 403 and the aluminum ring 402 moves downstream along with the first conveyor belt device 310 and thus enters below the rubbing plate 323 of the rubbing device 320. Since the rubbing plate 323 is connected to the output shaft of the first reduction motor 321 through the first crank arm 322, the rubbing plate 323 can swing by the rotation of the output shaft of the first reduction motor 321. And the rubbing plate 323 is also rotatably connected to the first frame 301 through a plurality of second crank arms 325, so that the rubbing plate 323 swings in a circular motion centered on the output shaft of the first reduction motor 321. Since the first conveyor belt device 310 and the rubbing plate 323 are spaced apart by a distance less than the height of the combination of the rubber stopper 403 and the aluminum ring 402, the rubber stopper 403 can be extruded, increasing the friction between the rubber stopper 403 and the first conveyor belt device 310 or between the rubber stopper 403 and the rubbing plate 323. When the rubbing plate 323 swings, the rubber stopper 403 is taken out of the aluminum ring 402, thus separating the rubber stopper 403 and the aluminum ring 402.

[0065] Furthermore, the rubber stopper-aluminum ring separation unit 300 further includes a rubber stopper-aluminum ring separation device 330. The rubber stopper-aluminum ring separation device 330 includes a second driving roller 331, a multi-stage magnetic roller 332, a third conveyor belt 333, and a third reduction motor 334. When the multi-stage magnetic roller 332 rotates, an alternating magnetic field is generated. When the aluminum ring 402 passes through the magnetic field, eddy currents are generated in the aluminum ring 402. The eddy currents themselves generate an alternating magnetic field, which is opposite to the magnetic field direction of the multi-stage magnetic roller 332. The interaction between the two magnetic fields generates an eddy current force, that is, a repulsive force on the aluminum ring 402. A partition 340 is installed in the fourth discharge hopper 350. The partition 340 divides the fourth discharge hopper 350 into two discharge channels. During operation, the aluminum ring 402 moves away from the multi-stage magnetic roller 332 through the repulsive force in one channel, while no magnetic field is generated in the rubber stopper 403 and it will not be repelled, so it falls into the channel close to the multi-stage magnetic roller 332, separating the aluminum ring 402 and the rubber stopper 403.
