Description

Technical Field

[0001] The present application relates to the technical field of plastic recycling, and particularly relates to a device and method for crushing and processing waste non-metallic plastic materials. Background Art

[0002] With the continuous increase in the consumption of non-metallic plastic material products, the amount of waste plastics is also increasing continuously. These products become an important source of waste plastics after being scrapped. If the storage, transportation, processing, application of waste plastic raw materials waiting to be processed, and post-treatment are not properly handled, it will inevitably damage the environment and endanger the health of the people. To process them, a crushing and processing device is often required.

[0003] The patent with the publication number CN207044484U discloses a plastic crushing device. This prior art realizes the rough crushing and fine crushing of polycarbonate plastics by setting a first crushing mechanism and a second crushing mechanism, improves the crushing accuracy of plastics, and has permanent magnets embedded on the inner wall of the feed hopper to separate plastics from metals during feeding, avoiding metal impurities from damaging the first crushing mechanism and the second crushing mechanism, and at the same time reducing the working load of the extruder in subsequent work.

[0004] However, the above prior art has the following technical defects: First, both the second crushing shaft and the third crushing shaft of this prior art are strip-shaped, and the entry of plastics between the second crushing shaft and the third crushing shaft each time is uncertain. If plastics only pass through a certain area of the crushing shaft for a long time, the blades on the crushing shaft in this area will be severely worn, reducing their service life, and the temperature will rise due to the long-term crushing of the blades, resulting in plastics adhering to them and being difficult to clean.

[0005] Second, this prior art uses a second filter screen to filter the crushed plastics. Plastics that do not meet the size will remain above the second filter screen, which requires manual cleaning by staff. And in order to ensure the filtering effect of the second filter screen, the staff needs to frequently clean the plastics on it, which invisibly increases the labor intensity of the staff.

[0006] In summary, there is still room for improvement in this prior art in terms of extending the service life of the crushing blades, preventing plastics from adhering to the blade surface, and reducing the labor intensity of the staff. Therefore, those skilled in the art have proposed a device that can evenly feed materials and automatically clean the plastics above the filter plate. Summary of the Invention

[0013] Preferably, a group of cross bars are installed on the side surface of the rectangular cylinder above each discharge port, and a baffle for blocking the discharge port on the same side is slidably arranged on the two cross bars in the group.

[0014] Preferably, a first spring is sleeved on the cross bar on one side of the push plate, and a pressure-receiving part extending into the rectangular cylinder is installed on the side surface of the baffle close to the rectangular cylinder.

[0015] Preferably, diversion grooves inclined outward are installed on the side surface of the rectangular cylinder below each discharge port, and discharge ports adapted to them are arranged on the side surface of the box body at the lower end of each diversion groove.

[0016] Preferably, a shaking mechanism is further provided. The shaking mechanism includes a mounting plate installed on the inner wall of the box body and on one side of the filter plate. A shaking motor is installed on one side of the mounting plate. The driving end of the shaking motor penetrates through the mounting plate and a turntable is installed.

[0033] The following will be combined with Figure 1 - Figure 10 to elaborate in detail on the embodiments of this application.

[0034] The embodiment of this application discloses a device and method for crushing and processing waste non-metallic plastic materials. By setting a feeding mechanism in which the inlet frame moves back and forth in the direction facing the crushing roller, during the continuous feeding process, the plastic raw materials are dispersed into different areas of the crushing roller, so that the area between the two crushing rollers can evenly pass the plastic, avoiding the situation that a certain area is fed for a long time, resulting in serious wear of the corresponding area of the blade, prolonging the service life of the crushing roller, also avoiding the situation that the temperature rises due to the long-time crushing of the blade and the plastic adheres to it, and also reducing plastic blockage.

[0035] Embodiment 1: As Figure 1 and Figure 3As shown in the figure, it includes a crushing mechanism 1. The crushing mechanism 1 includes a box body 101. A strip-shaped groove 105 is opened at the center of the upper side of the box body 101. After the rough crushing of the external waste non-metallic plastic materials, they enter the box body 101 through the strip-shaped groove 105 for refined crushing and processing.

[0036] As Figure 3 shown in the figure, a group of crushing rollers 102 are symmetrically installed on the inner wall of the box body 101. A group of inwardly inclined guide plates 106 are installed above the crushing rollers 102. The guide plates 106 are used to guide the plastic materials entering the box body 101, so that they fall between the two crushing rollers 102. At the same time, the two oppositely rotating crushing rollers 102 are used to refine and crush the passing plastics.

[0037] As Figure 3 shown in the figure, one end of the two crushing rollers 102 extends to the outside of the box body 101 and is installed with meshing gears 104. On the side of the box body 101, a crushing motor 103 with a driving end connected to the other end of the crushing roller 102 is installed on the side of one of the crushing rollers 102. The running crushing motor 103 drives the connected crushing roller 102 to rotate. Then, the two gears 104 drive the other crushing roller 102 to rotate in the opposite direction, so that the two crushing rollers 102 rotate towards each other.

[0038] In summary, when the crushing motor 103 runs, the two crushing rollers 102 rotate towards each other. The roughly crushed plastics fall from the strip-shaped groove 105 into the box body 101. After being guided by the guide plates 106, the plastics fall between the two crushing rollers 102. The two oppositely rotating crushing rollers 102 are used to refine and crush the passing plastics and break them into plastic particles.

[0039] As Figure 2 and Figure 4 shown in the figure, it includes a feeding mechanism 2. The feeding mechanism 2 includes a mouth-shaped frame 201 located directly above the strip-shaped groove 105. A feeding frame 202 adapted to it is slidably arranged in the strip-shaped groove 105. A conical connecting cloth bag 203 with its lower end connected to the feeding frame 202 is also arranged at the lower port of the mouth-shaped frame 201. When plastics are put into the mouth-shaped frame 201, they are guided by the connecting cloth bag 203 and enter the box body 101 from the feeding frame 202 and the strip-shaped groove 105. At the same time, the connecting cloth bag 203 is flexible and can change its shape as the feeding frame 202 moves.

[0040] As Figure 4 shown in the figure, the moving component includes a screw rod 204 rotatably installed on the upper side of the box body 101 and on one side of the feeding frame 202. A reduction motor 205 with a driving end connected to one end of the screw rod 204 is installed on the upper side of the box body 101. A threaded seat 206 connected to the feeding frame 202 is arranged on the screw rod 204. When the running reduction motor 205 drives the screw rod 204 to rotate, the rotating screw rod 204 drives the threaded seat 206 to move, thereby driving the feeding frame 202 to move.

[0041] As Figure 2 shown, a slide bar 5 is installed on the upper side of the box body 101 on the other side of the feeding frame 202. A slider 6 connected to the feeding frame 202 is slidably arranged on the slide bar 5. The moving feeding frame 202 drives the slider 6 to slide on the slide bar 5, enhancing the stability of the feeding frame 202 during movement.

[0042] In summary, the operating reduction motor 205 drives the screw 204 to rotate, driving the threaded seat 206 to move. When the threaded seat 206 moves to the end of the screw 204, the screw 204 is driven to reverse, causing the reduction motor 205 to move in the opposite direction. Repeating the above operations realizes the reciprocating movement of the threaded seat 206 on the screw 204, driving the feeding frame 202 to reciprocate in the strip groove 105, which can change the position of the plastic passing between the two crushing rollers 102. During the continuous feeding of the plastic into the mouth-shaped frame 201, the reciprocating feeding frame 202 allows the plastic to evenly pass through the area between the two crushing rollers 102, ensuring that each blade on the crushing roller 102 can crush the plastic. At the same time, when the blades below the feeding frame 202 crush the plastic, the blades far from the feeding frame 202 can be cooled because they do not crush the plastic, avoiding the situation where the blades adhere to the plastic due to overheating caused by long-term plastic crushing.

[0043] As Figure 5 and Figure 6 shown, it further includes a filtering mechanism 3. The filtering mechanism 3 includes a rectangular cylinder 301 installed inside the box body 101 and extending to the lower surface of the box body 101 at the lower end. A filter plate 303 with both sides extending outside the rectangular cylinder 301 is slidably arranged in the rectangular cylinder 301. The filter plate 303 can be used to filter the refined and fragmented plastic. The plastic particles that meet the size pass through the filter plate 303, while the ones that do not remain above the filter plate 303.

[0044] As Figure 5 and Figure 6 shown, discharge ports 302 are opened on both sides of the rectangular cylinder 301 above the filter plate 303. A push plate 308 is slidably arranged above the filter plate 303. A connecting frame 309 is installed between the feeding frame 202 and the push plate 308. The moving feeding frame 202 drives the push plate 308 to reciprocate above the filter plate 303 through the connecting frame 309. The moving push plate 308 can push the large plastic particles above the filter plate 303 out of the discharge port 302 in the moving direction.

[0045] As Figure 5 and Figure 6As shown, an upper funnel 311 adapted to the inner cavity of the box body 101 is installed at the upper port of the rectangular cylinder 301, and a lower funnel 312 extending to the outside of the box body 101 is installed at the lower port of the rectangular cylinder 301. The refined and crushed plastic particles enter the rectangular cylinder 301 through the upper funnel 311, and the plastic filtered by the filter plate 303 enters the lower funnel 312 and is discharged from its lower port.

[0046] As Figure 5 and Figure 6 shown, a group of cross bars 304 are installed on the side of the rectangular cylinder 301 above each discharge port 302. A baffle 306 for blocking the discharge port 302 on the same side is slidably arranged on the two cross bars 304 in the group. A first spring 305 is sleeved on the cross bar 304 on one side of the push plate 308. A pressure receiving member 307 extending into the rectangular cylinder 301 is installed on the side of the baffle 306 close to the rectangular cylinder 301. The push plate 308 can be used to block the discharge port 302. At the same time, the push plate 308 moving towards the discharge port 302 will squeeze the pressure receiving member 307, thereby driving the baffle 306 to move, compressing the first spring 305 and opening the discharge port 302.

[0047] As Figure 5 and Figure 6 shown, a diversion groove 310 inclined outwards is installed on the side of the rectangular cylinder 301 below each discharge port 302. A discharge port 108 adapted to it is opened on the side of the box body 101 at the lower end of each diversion groove 310. The large particle plastics pushed out from the discharge port 302 fall on the diversion groove 310 and flow out from the discharge port 108 through its diversion.

[0048] In summary, the refined and fragmented plastics fall into the upper funnel 311, and fall on the filter plate 303 from its lower port. The filter plate 303 is used to filter the plastics. The plastic particles that meet the size pass through the filter plate 303 and fall into the lower funnel 312 and are discharged, while the ones that do not meet the size remain above the filter plate 303. The moving feeding frame 202 drives the push plate 308 to reciprocate above the filter plate 303 through the connecting frame 309, and at the same time pushes the large particle plastics above the filter plate 303 to move in the same direction. When the push plate 308 squeezes the pressure receiving member 307 in the moving direction, it will push it to move, drive the baffle 306 to move, compress the first spring 305 and open the discharge port 302. Then, the continuously moving push plate 308 pushes the large particle plastics on the same side as its moving direction out of the opened discharge port 302, and then falls on the diversion groove 310 and is discharged and collected from the discharge port 108. Then, the push plate 308 moves in the reverse direction. Without the extrusion, the first spring 305 rebounds to drive the baffle 306 to recover and close the discharge port 302. Then, the reversely moving push plate 308 repeats the operation to push the newly filtered large particle plastics on this filter plate 303 out of another discharge port 302.

[0049] As Figures 7 - 9As shown, a shaking mechanism 4 is further provided. The shaking mechanism 4 includes a mounting plate 401 installed on the inner wall of the box body 101 and on one side of the filter plate 303. A shaking motor 413 is installed on one side of the mounting plate 401. The driving end of the shaking motor 413 penetrates through the mounting plate 401 and a turntable 402 is installed. The running shaking motor 413 drives the turntable 402 to rotate.

[0050] As Figures 8 - 9 shown, at the edge where the filter plate 303 extends to the outside of the rectangular cylinder 301, a U-shaped seat 404 connected thereto is provided. A connecting rod 403 with its end rotatably connected to the side of the U-shaped seat 404 is rotatably installed on the side edge of the turntable 402. The rotating turntable 402 pulls the filter plate 303 to shake reciprocally through the connecting rod 403 and the U-shaped seat 404, improving its filtering efficiency and avoiding particle accumulation.

[0051] Embodiment 2: On the basis of Embodiment 1, as Figure 8 and Figure 10 shown, a U-shaped plate 407 is installed on the upper side of the U-shaped seat 404. An active plate 408 is arranged between the inner sides of the U-shaped plate 407. A group of vertical rods 409 are symmetrically installed on the upper side of the active plate 408. The upper ends of all the vertical rods 409 in the group penetrate through the U-shaped plate 407 and a pull ring 410 is installed together. A plurality of uniformly distributed second springs 411 are connected between the U-shaped plate 407 and the active plate 408. Pulling the pull ring 410 upward will drive the active plate 408 to rise through the vertical rods 409 and compress the second springs 411 at the same time. When the second springs 411 rebound, they will drive the position of the active plate 408 to be restored.

[0052] As Figure 8 and Figure 10 shown, a group of card slots 313 are symmetrically opened on the upper side of the filter plate 303. A card member 412 adapted thereto and having its upper end connected to the active plate 408 is arranged in the card slots 313. Letting the card member 412 be inserted into the card slots 313 connects and fixes the U-shaped seat 404 and the filter plate 303. Pulling the push plate 308 upward will drive the card member 412 out of the card slots 313, and the fixation can be released.

[0053] As Figure 2 and Figure 7 shown, box doors 107 of the same height as the filter plate 303 are arranged on the front and rear sides of the box body 101. By opening the two box doors 107, the user can reach into the box body 101 to operate the pull ring 410 or the filter plate 303.

[0054] In summary, when replacing the filter plate 303, open the two cabinet doors 107. The user reaches into the cabinet door 107 near the pull ring 410 with their hand and pulls up the pull ring 410, pulling the movable plate 408 upward. While compressing the second spring 411, the clamping member 412 is driven out of the card slot 313, releasing the connection between the filter plate 303 and the U-shaped seat 404. Then, the user extracts the filter plate 303 through the other cabinet door 107 and inserts a filter plate 303 with a filter hole size adapted to the plastic particles required next. Let the edge of the filter plate 303 be snapped into the U-shaped seat 404, and align the two card slots 313 with the clamping member 412. Release the pull ring 410 to let the second spring 411 rebound and drive the movable plate 408 to return to its original position, driving the clamping member 412 to snap into the card slot 313 to complete the fixation. Then, close the two cabinet doors 107.

[0055] The present invention also discloses a method for crushing and processing waste non-metallic plastic materials. The steps of this method are as follows: S1. Uniform feeding: The coarsely crushed plastic is uniformly fed into any area between the two crushing rollers 102 through the feeding mechanism 2. Specifically, feed the material into the orifice-shaped frame 201. The plastic is discharged from the feeding frame 202 through the connecting cloth bag 203 and falls vertically. The running reduction motor 205 drives the screw 204 to rotate forward and backward, causing the threaded seat 206 to reciprocate on the screw 204, driving the feeding frame 202 to reciprocate in the strip-shaped groove 105, which can change the falling position of the plastic, making the falling position cover the area between the two crushing rollers 102. Thus, during the continuous feeding of the orifice-shaped frame 201, the reciprocating feeding frame 202 allows any area between the two crushing rollers 102 to evenly pass the plastic.

[0056] S2. Plastic crushing: The plastic passing between the two crushing rollers 102 is subjected to refined crushing and processing. Specifically, the crushing motor 103 runs to make the two crushing rollers 102 rotate towards each other. The plastic discharged from the feeding frame 202 falls vertically between the two crushing rollers 102. The two crushing rollers 102 rotating towards each other are used to refine and crush the passing plastic, crushing it into plastic particles.

[0057] S3. Plastic filtering: The filtering mechanism 3 is used in cooperation with the shaking mechanism 4 to filter the refined and crushed plastic. Specifically, the refined and crushed plastic falls into the upper funnel 311 and falls from its lower port onto the filter plate 303. The filter plate 303 is used to filter the plastic. The plastic particles that meet the size pass through the filter plate 303 and fall into the lower funnel 312 for discharge and collection. At the same time, the shaking motor 413 runs to drive the turntable 402 to rotate. The rotating turntable 402 pulls the filter plate 303 to reciprocate through the connecting rod 403 and the U-shaped seat 404, improving its filtering efficiency and preventing particle accumulation.

[0058] S. Cleaning of large plastic particles. The filtering mechanism 3 is used in cooperation with the feeding mechanism 2 to clean and collect the large plastic particles that do not meet the size requirements above the filter plate 303. Specifically, the moving feeding frame 202 drives the push plate 308 to reciprocate above the filter plate 303 through the connecting frame 309, and at the same time pushes the large plastic particles above the filter plate 303 to move in the same direction. When the push plate 308 presses against the pressure-receiving part 307 in the moving direction, it will push it to move, drive the baffle 306 to move, compress the first spring 305 while opening the discharge port 302. Then, the continuously moving push plate 308 will push the large plastic particles on the same side as its moving direction out of the opened discharge port 302, and then fall on the diversion groove 310 and be discharged and collected from the discharge port 108. After that, the push plate 308 moves in the reverse direction. Without the extrusion, the first spring 305 rebounds to drive the baffle 306 to restore and close the discharge port 302. Then, the reversely moving push plate 308 repeats the operation to push the newly filtered large plastic particles on this filter plate 303 out of the other discharge port 302.
