Description

Technical Field

[0001] The invention relates to the field of plastic processing devices, in particular to a plastic crusher with an anti-splashing function. Background Art

[0002] Plastic is a widely used high molecular polymer material. Plastic products are used in all areas of people's lives. The use of plastic products inevitably causes a large amount of plastic pollution. Therefore, it is necessary to recycle plastic products to reduce pollution to the ecological environment and realize their reuse value.

[0003] When plastics are recycled and reused, they need to be crushed. The crushed plastics not only free up space and are easy to store, but also facilitate the subsequent decomposition and granulation processes. There are many kinds of existing crushing equipment, most of which use one or more sets of crushing rollers or rolling blades for processing. In this process, plastic debris is often splashed everywhere. The splash of such plastic debris is due to the curved shape of the plastic products themselves. When they are squeezed and crushed, it is very easy to cause uneven stress distribution on the cross section and break or crack, causing splashing. On the other hand, due to the flow difference between feeding and unloading, sufficient energy is transferred to the plastic at the high-speed rotating crushing roller or rolling blade, causing splashing. The occurrence of plastic splashing not only causes waste of the material itself, but also has an adverse effect on the operating workshop environment and operators.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Specifically, the circulating rolling assembly 3 includes an upper push plate 301, a lower push plate 302, an intermittent gear 306 and a rolling plate 307. The upper push plate 301 and the lower push plate 302 are arranged in parallel and spaced apart in the device bin 101. The ends of the upper push plate 301 and the lower push plate 302 facing the feed channel 102 are provided with a rolling plate 307. The width of the rolling plate 307 is the same as the width of the feed channel 102, so as to ensure that the rolling plate 307 effectively covers the feed channel 102 during reciprocating motion. The ends of the upper push plate 301 and the lower push plate 302 away from the feed channel 102 are connected to each other by a connecting rod 303. An intermittent gear 306 is rotatably arranged between the upper push plate 301 and the lower push plate 302. The cross-sectional center of the intermittent gear 306 passes through The first rotating shaft 311 is connected to the output end of the first motor 309, and the first motor 309 is fixedly installed in the device bin 101 of the pre-treatment box 1. The upper push plate 301 is provided with an upper tooth block 304 meshing with the tooth pattern segment of the intermittent gear 306, and the lower push plate 302 is provided with a lower tooth block 305 meshing with the tooth pattern segment of the intermittent gear 306. The two end surfaces of the rolling plate 307 in the telescopic direction are provided with fine rolling teeth, and the inner wall of the feeding channel 102 is provided with a tooth pattern contact plate 308 matching the rolling teeth on the rolling plate 307; before the plastic enters the crushing box 2 for crushing, it first passes through the pre-treatment box 1. When the plastic is put into the feeding channel 102 of the pre-treatment box 1, the first motor 309 is started and drives the intermittent gear 306. The upper push plate 301 is driven to move to the right by the tooth segment on the intermittent gear 306 and the upper tooth block 304 on the upper push plate 301 and meshing transmission occurs, and the upper push plate 301 and the lower push plate 302 are connected by the connecting rod 303, so that the ends of the upper push plate 301 and the lower push plate 302 facing the feed channel 102 move to the right at the same time, and the rolling plate 307 rolls the passing plastic on the tooth contact plate 308 on the right side of the feed channel 102. When the intermittent gear 306 continues to rotate, the transmission meshing with the upper tooth block 304 on the upper push plate 301 is released, and the lower tooth block 305 on the lower push plate 302 is contacted and meshing transmission occurs, which drives the upper push plate 301 and the lower push plate 302 to move to the left and are rolled on the feed channel. The plastic on the toothed contact plate 308 on the right side of the feed channel 102 falls off immediately, and the plastic that passes through is rolled by the rolling plate 307 on the toothed contact plate 308 on the left side of the feed channel 102, and the plastic rolling is repeated in this way. Possible bottle-shaped, basin-shaped or other plastic products with curved corners are processed into flat sheets, thereby avoiding the breakage or cracking of plastic products due to uneven cross-sectional stress distribution caused by the curved surface shape during extrusion and crushing, and reducing the occurrence of splashing caused by this. At the same time, the reciprocating rolling setting in front of the crushing port is used to adjust the feed flow rate. At the same time, the flattened plastic is not easy to accumulate at the crushing port compared to the plastic before processing, which plays a positive role in accelerating the crushing process.

[0035] Specifically, a slide groove 310 matching the rolling plate 307 is provided on the inner wall of the feed channel 102, and the rolling plate 307 is slidably installed in the slide groove 310 to ensure the stability of the horizontal reciprocating motion of the rolling plate 307 driven by the upper push plate 301 and the lower push plate 302, and smoothly perform the reciprocating rolling of the passing plastic.

[0036] Preferably, the feed channel 102 can be vertically arranged, and the feed channel 102 can also be inclined as needed, so that the plastic slides through the feed channel 102 by gravity in the feed channel 102 and receives a more sufficient rolling action of the circulating rolling assembly 3.

[0037] Specifically, the pulverizing assembly 4 is located at the lower end of the pulverizing box 2, and a pulverizing slot 402 facing the feed channel 102 is provided on the box body 401 of the pulverizing assembly 4. The pulverizing assembly 4 includes a main pulverizing roller 403, a driving gear 404, an auxiliary pulverizing roller 406 and a driven gear 407. A second motor 409 is installed in the box body 401, and an output end of the second motor 409 is connected to a second rotating shaft 405 that passes through the pulverizing slot 402. The main pulverizing roller 403 is installed on the second rotating shaft 405 in the pulverizing slot 402, and a driving gear 404 is also provided on the second rotating shaft 405. A driven gear that meshes with the driving gear 404 is provided in the box body 401. 407, the driven gear 407 is installed on the third rotating shaft 408, and the third rotating shaft 408 in the pulverizing groove 402 is also provided with an auxiliary pulverizing roller 406 arranged parallel to the main pulverizing roller 403; when pulverizing is in progress, the plastic that has been pre-treated by rolling falls into the pulverizing groove 402 from the lower end of the feed channel 102, and the second motor 409 drives the main pulverizing roller 403 to rotate, and at the same time, the third rotating shaft 408 is driven to rotate by utilizing the meshing action of the driving gear 404 and the driven gear 407, so that the auxiliary pulverizing roller 406 and the main pulverizing roller 403 rotate synchronously in the opposite direction and rotate in opposite directions, so that the plastic passes through its gap and receives sufficient pulverization.

[0038] Specifically, the pulverizing groove 402 is also provided with a fixed pulverizing tooth 410 arranged between the inner wall of the pulverizing groove 402 and the gap between the main pulverizing roller 403 and the auxiliary pulverizing roller 406. The fixed pulverizing tooth 410 is fixedly arranged on the inner wall of the pulverizing groove 402. The setting of the fixed pulverizing tooth 410 prevents flat sheet-like plastic from falling directly, thereby ensuring the pulverizing effect of the plastic when it passes through the pulverizing component 4.

[0039] Specifically, the pulverizing slot 402 is surrounded by inclined baffles, the pulverizing box 2 is provided with an annular splash collecting slot 6 surrounding the box body 401 of the pulverizing assembly 4, the pulverizing reflux assembly 5 is arranged at the lower end of the splash collecting slot 6, the pulverizing reflux assembly 5 includes a turntable 501, a driving gear 502 and a pulverizing disc 503, the driving gear 502 is arranged on the outside of the lower barrel 7, the center of the turntable 501 is provided with a mounting hole matching the lower barrel 7, the turntable 501 is sleeved on the outside of the lower barrel 7, and the turntable 501 is rotatably mounted on the In the crushing box 2, a slot 507 matching the turntable 501 is provided on the inner wall of the crushing box 2, so that the turntable 501 is stably placed in the crushing box 2 and rotates around the fixed unloading barrel 7. A driving gear 502 is rotatably installed in the turntable 501, and the driving gear 502 is connected to the output end of the third motor 505 through a fourth rotating shaft 506. The turntable 501 is provided with an inner gear ring meshing with the driving gear 502, so that when the third motor 505 drives the gear 502 to rotate, it slides in the crushing box 2. The fourth rotating shaft 506 is provided on the turntable 501. The upper end of 06 is connected to the first bevel gear 508 in the direction-changing gear box 504, and the direction-changing gear box 504 is provided with a second bevel gear 509 opposite to the first bevel gear 508. The direction-changing gear box 504 is also provided with a vertical third bevel gear 510 that meshes with the first bevel gear 508 and the second bevel gear 509. The second bevel gear 509 is connected to the crushing disk 503 at its upper end through a rotating shaft. The crushing disk 503 is provided with a plurality of crushing rods 511 around it. The lower barrel 7 is provided with a reflux inlet 510 in the tangential direction of the rotation of the crushing disk 503. 12. In addition, a driving pulley 513 arranged at the lower end of the driving gear 502 is also installed on the fourth rotating shaft 506, and the driving pulley 513 is connected to a driven pulley 515 through a transmission belt 514, and the driven pulley 515 is connected to an auxiliary disk 516 in the same plane as the crushing disk 503 through a fourth rotating shaft 518. A plurality of auxiliary rods 517 are arranged around the auxiliary disk 516. The auxiliary disk 516 and the crushing disk 503 are arranged on both sides of the reflux inlet 512, and the rotation trajectories of the auxiliary rod 517 and the crushing rod 511 do not interfere with each other;When the crushing component 4 is crushing, although the plastic has been flattened, splashing during crushing is still inevitable. The splashing upward encounters the falling plastic to be crushed, and is merged and falls back into the crushing slot 402. The plastic splashing around, except for falling back into the crushing slot 402 through the inclined baffle, the rest of the plastic falls onto the turntable 501 through the splash collecting slot 6. The third motor 505 drives the gear 502 to rotate counterclockwise, and the turntable 501 uses its inner gear ring to mesh with the driving gear 502 to rotate counterclockwise in the crushing box 2 and fall into the turntable 501. The splashed plastic on the rotating table 501 rotates in the crushing box 2. Under the action of centrifugal force, the splashed plastic will gradually move away from the rotation center of the rotating table 501 and move toward one side of the inner wall of the crushing box 2. At the same time, the crushing plate 503 rotates. The first bevel gear 508, the third bevel gear 510 and the second bevel gear 509 in the direction-changing gear box 504 are used to drive the crushing plate 503 to rotate clockwise in the opposite direction of the rotation of the unloading barrel 7. The auxiliary plate 516 is driven by the driving pulley 513, the driven pulley 515 and the fourth rotating shaft 518, and the rotating table 50 1 rotates in the same direction as the crushing disk 503, and thus rotates in the opposite direction to the crushing disk 503. When the splashed plastic on the turntable 501 close to the inner wall of the crushing box 2 moves with the turntable 501 to the crushing disk 503 and the auxiliary disk 516, it contacts the crushing disk 503 and the auxiliary disk 516 that are rotating. Part of the splashed plastic directly collides with the crushing rod 511 on the counter-rotating crushing disk 503, and the rest is driven by the auxiliary disk 516 to accelerate close to the crushing disk 503, and a material discharge channel leading to the reflux inlet 512 is formed between the crushing disk 503 and the auxiliary disk 516. In this channel, the plastic constantly collides with the crushing disk 503 and the auxiliary disk 516. The crushing rod 511 on the 6 and the auxiliary rod 517 contact and collide, and while completing the reflux, the crushing effect of the collected splashed plastic is further improved. After being transported and crushed again in the discharge channel between the crushing disk 503 and the auxiliary disk 516, the splashed plastic of this part is thrown into the discharge barrel 7, and contacts and merges with the crushed plastic that normally falls in the discharge barrel 7, and finally discharged from the discharge hopper 8 at the lower end of the discharge barrel 7. The collection, crushing and confluence of the splashed plastic are comprehensively realized, and the splashing phenomenon during plastic crushing is avoided, which brings about the waste of raw materials and the adverse effects on the operating environment and personnel. ;

[0040] During specific operation: the plastic first passes through the pretreatment box 1, and when the plastic is put into the feed channel 102 of the pretreatment box 1, the first motor 309 is started and drives the intermittent gear 306 to rotate clockwise. When the tooth segment on the intermittent gear 306 contacts and meshes with the upper tooth block 304 on the upper push plate 301, the upper push plate 301 is driven to move to the right by the meshing action. The upper push plate 301 and the lower push plate 302 are connected by the connecting rod 303, so that the ends of the upper push plate 301 and the lower push plate 302 facing the feed channel 102 move to the right at the same time, and the rolling plate 307 rolls the passing plastic on the tooth contact plate 308 on the right side of the feed channel 102. When the intermittent gear 306 continues to rotate, the transmission meshing with the upper tooth block 304 on the upper push plate 301 is released, and the lower tooth block 305 on the lower push plate 302 is contacted and meshes. When the upper push plate 301 and the lower push plate 302 are moved to the left, the plastics crushed on the toothed contact plate 308 on the right side of the feed channel 102 fall down immediately, and the plastics passing through are crushed on the toothed contact plate 308 on the left side of the feed channel 102 by the crushing plate 307, and the plastics are crushed in a reciprocating manner in the feed channel 102, and the possible bottle-shaped, basin-shaped or other plastic products with curved corners are processed into flat sheets, so as to avoid the plastic products from breaking or cracking due to the uneven stress distribution of the cross section caused by the curved surface shape during extrusion and crushing, and reduce the occurrence of splashing caused by this. At the same time, the reciprocating crushing setting in front of the crushing port plays a role in adjusting the feed flow rate. At the same time, the flattened plastics are not easy to accumulate at the crushing port compared with the plastics before processing, which plays a positive role in accelerating the crushing.The pre-treated plastic falls into the crushing slot 402 of the crushing assembly 4, and is crushed by the main crushing roller 403 and the auxiliary crushing roller 406 rotating in opposite directions. In this process, splashing during crushing is still inevitable. The splashing upward encounters the falling plastic to be crushed, and is merged and falls back into the crushing slot 402. The plastic splashing around, except for falling back into the crushing slot 402 through the inclined baffle, the rest of the plastic falls onto the turntable 501 through the splash collecting slot 6. The third motor 505 drives the gear 502 to rotate counterclockwise, and the turntable 501 uses The inner gear ring is meshed with the driving gear 502, and the crushing box 2 rotates counterclockwise. The splashed plastics falling on the turntable 501 rotate with the turntable 501 in the crushing box 2. Under the action of centrifugal force, the splashed plastics will gradually move away from the rotation center of the turntable 501 and move toward one side of the inner wall of the crushing box 2. The crushing plate 503 also rotates together. The first bevel gear 508, the third bevel gear 510 and the second bevel gear 509 in the change gear box 504 are used to drive the crushing plate 503 to rotate synchronously with the unloading barrel 7. In the opposite clockwise rotation, when the splashed plastic on the turntable 501 close to the inner wall of the crushing box 2 moves with the turntable 501 to the crushing plate 503 and the auxiliary plate 516, they are in contact with the rotating crushing plate 503 and the auxiliary plate 516. Part of the splashed plastic directly collides with the crushing rod 511 on the counter-rotating crushing plate 503, and the rest is driven by the auxiliary plate 516 to accelerate close to the crushing plate 503, and a material discharge channel leading to the reflux inlet 512 is formed between the crushing plate 503 and the auxiliary plate 516. In this channel, the plastic is constantly in contact with the crushing plate 503 and the auxiliary plate 516. The crushing rod 511 on the plate 516 and the auxiliary rod 517 contact and collide, and while completing the reflux, the crushing effect of the collected splashed plastic is further improved. After being transported and crushed again in the discharge channel between the crushing plate 503 and the auxiliary plate 516, it contacts and converges with the crushed plastic that normally falls in the discharge barrel 7, and finally discharges out of the device from the discharge hopper 8 at the lower end of the discharge barrel 7, which comprehensively realizes the collection, re-crushing and confluence of the splashed plastic, avoiding the splashing phenomenon during plastic crushing, which brings about the waste of raw materials and the adverse effects on the operating environment and personnel. ;

[0041] Embodiment 2: The difference between the embodiment of the present invention and embodiment 1 is that the turntable 501 in the crushing and reflux assembly 5 is changed from a horizontal setting to an inclined setting, and the horizontal height of one end of the turntable 501 on which the driving gear 502 and the crushing disc 503 are installed is lower than that of the other end.

[0042] During specific operation, this inclined design, on the one hand, allows the splashed plastic to quickly move toward the side of the crushing disk 503 due to gravity, making it easier for the plastic to flow into the lower barrel 7. On the other hand, when the plastic is tilted, when the crushing rod 511 is driven by the rotation and thrown into the lower barrel 7, it has an upward movement trend, and the collision effect with the normally falling plastic is more obvious, which plays a role of auxiliary crushing and obvious loose material, and is conducive to the subsequent plastic recycling processing.

[0043] Example 3: Please refer to Figure 9-10 The embodiment of the present invention is based on the embodiment 1 and the embodiment 2, and upgrades the function of a plastic crusher with an anti-splashing function. Specifically, the upper end of the pretreatment box 1 is also provided with a reciprocating sliding cover assembly 9 to prevent the circulating crushing assembly 3 from generating splashes during operation. The reciprocating sliding cover assembly 9 includes a connecting frame 901, a slider 902 and a shield 904. The shield 904 is slidably arranged on the upper end of the pretreatment box 1, and the shield 904 can partially block the opening of the feed channel 102. The shield 904 is connected to the slidingly installed slider 902 through a connecting rod 903, and the lower end of the slider 902 is connected to the upper push plate 301 of the circulating crushing assembly 3 through a connecting frame 901.

[0044] When the circulating rolling component 3 performs a cyclical rolling process on the plastic, its tendency to move toward the feed channel 102 is transmitted to the slider 902 through the connecting frame 901, driving the slider 902 and the connecting rod 903 and the baffle 904 connected to the slider 902 to move to the right. When rolling is performed on the right inner wall of the feed channel 102, the baffle 904 is located directly above the rolling position. Similarly, the baffle 904 is always kept at the upper end of the rolling working position, effectively preventing splashing that may occur during the rolling operation.

[0045] Example 4: Please refer to Fig.11 Based on Example 1, this embodiment further improves the functionality of the crushing and reflux component 5. A fourth bevel gear 10 is provided on the fourth rotating shaft 506 connected to the output end of the third motor 505. A fifth bevel gear 11 meshing with the fourth bevel gear 10 is provided in the crushing box 2. The fifth bevel gear 11 is connected to a fifth rotating shaft 12 arranged for horizontal rotation. The fifth rotating shaft 12 is located in the discharge barrel 7 and a plurality of blades 13 are also provided on the fifth rotating shaft 12.

[0046] When the crushing and reflux component 5 is working, the third motor 505 continues to work, and it also drives the fourth bevel gear 10 to rotate, and utilizes the meshing transmission with the fifth bevel gear 11 to drive the fifth rotating shaft 12 to rotate in the discharge barrel 7. It contacts with the falling processed plastic, which can loosen the raw materials for subsequent processing and use, and on the other hand, it can guide the materials to pass quickly to avoid blockage and the like.
