Description

Technical Field

[0001] This invention relates to the field of plastic recycling and crushing technology, specifically to a crushing and granulation device for recycling waste plastics that prevents material jamming. Background Technology

[0002] Waste plastic recycling is a core link in solving "white pollution" and realizing resource recycling. It involves the entire process of recycling system, pretreatment, crushing, washing, granulation and recycling. At the same time, it needs to deal with challenges such as difficulty in classification, many impurities, and large differences in recycled quality. Waste plastic recycling crushing is the core pretreatment link in the waste plastic recycling process. It connects "front-end material sorting" and "back-end washing and granulation". Its core goal is to crush waste plastics of different shapes and sizes, such as large scraps, waste products, and mixed waste, into "uniform particles that are suitable for subsequent processing", laying the foundation for efficient subsequent washing, drying and granulation.

[0003] When crushing plastic, the moving blade disc is driven by an electric motor to rotate at high speed, forming a relative motion with the fixed blade. The gap between the moving and fixed blades creates a cutting edge for crushing and shearing the plastic. The plastic is crushed under the action of shearing force. However, during shearing, the plastic is easily driven into the gap between the blades by the shearing force, causing material jamming and resulting in larger particle size of the crushed particles. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A waste plastic recycling crushing and granulation device with anti-jamming features, comprising:

[0006] The crushing chamber has a bottom support plate fixedly installed at its bottom, and a feed chute and a discharge chute are installed on the upper and lower sides of the crushing chamber.

[0007] The material guiding mechanism is installed inside the crushing chamber;

[0008] A screening mechanism is installed inside a bottom support plate. A cylinder is fixedly installed on the outside of the bottom support plate. The output end of the cylinder passes through the bottom support plate and extends into it. The output end of the cylinder is fixedly connected to the outside of the screening mechanism.

[0009] A motor is fixedly installed on the outer side of the crushing chamber, and a drive shaft is rotatably installed on the inner wall of the crushing chamber. One end of the drive shaft is fixedly connected to the output end of the motor via a coupling. A cutter shaft cylinder is fixedly installed on the outer side of the drive shaft, and a crushing ring cutter is fixedly installed on the outer side of the cutter shaft cylinder. Protrusions are evenly distributed on the outer side of the crushing ring cutter, and the crushing ring cutters are evenly installed on the outer side of the cutter shaft cylinder. A side baffle is fixedly installed on the inner wall of the crushing chamber away from the material guiding mechanism. Arc grooves are evenly formed on the side baffle near the cutter shaft cylinder, and each arc groove corresponds to a crushing ring cutter. A partition block is fixedly installed on the side baffle near the cutter shaft cylinder, and the partition block cooperates with the crushing ring cutter and the side baffle. The separator blocks waste plastic between the crushing ring cutters to prevent it from getting stuck in the non-shearing crushing position between the cutter shaft cylinder and the side retaining ring under the shearing force, thus avoiding material jamming and affecting the shearing and crushing of waste plastic. At the same time, the separator blocks at the arc groove position of the side baffle restrict the waste plastic, so that the volume of waste plastic being sheared by the cutter during shearing and crushing is reduced, avoiding the jamming of large-volume plastic, which would also result in larger particle sizes and reduce the crushing effect. The side of the separator block near the cutter shaft cylinder is in close contact with the outer side of the cutter shaft cylinder, and the top of the separator block is higher than the top of the side baffle, and the top of the side baffle is a sloped downward towards the cutter shaft cylinder.

[0010] Preferably, fixed end plates are fixedly installed at both ends of the inner wall of the crushing chamber. Each fixed end plate has an annular protrusion on its opposite surface. Annular grooves are provided at both ends of the cutter shaft cylinder, and these grooves rotatably adapt to the annular protrusions of the fixed end plates. Side baffles are fixedly installed at both ends of the inner wall of the crushing chamber. The conical surface of the side baffles engages with the inclined surface at the top of the side baffle plate to guide the waste plastic during input, ensuring it reaches the shearing and crushing position smoothly. Simultaneously, the side baffles restrict the plastic at both ends of the crushing chamber, preventing it from entering the non-crushing areas and getting stuck at both ends during rotation, thus affecting the rotation of the crushing cutter. Furthermore, the fixed end plates restrict the rotation center position of the cutter shaft cylinder during shearing and crushing, preventing displacement under shearing reaction force and thus avoiding significant wear on the cutter. The side baffles are located directly above the fixed end plates, and the edges of the opposite surfaces of the side baffles are conical.

[0011] Preferably, the material guiding mechanism includes a fixed plate, which is fixedly installed on the inner wall of the crushing chamber away from the side baffle. An arc baffle is fixedly installed on the top of the fixed plate. The arc baffle cooperates with the arc convex plate. The inclined surface of the top of the arc baffle guides the introduced plastic while the arc convex plate tightly fits between the crushing ring cutters and the outer side of the cutter shaft cylinder, sealing the gaps between the side baffles. This allows the introduced plastic to smoothly enter the crushing position under the rotation of the crushing ring cutters, preventing the introduced plastic from failing to enter the crushing position and causing material accumulation in the crushing chamber. The top of the arc baffle is an inclined surface that slopes from top to bottom towards the side baffle. Grooves are evenly provided on the side of the fixed plate near the cutter shaft cylinder, and the grooves of the fixed plate correspond one-to-one with the crushing ring cutters. The outer side of the arc baffle is tightly fitted to the inner wall of the crushing chamber, and an arc convex plate is fixedly installed on the inner wall of the arc baffle.

[0012] Preferably, the side of the arc-shaped convex plate away from the arc-shaped baffle is tightly fitted to the outer side of the cutter shaft cylinder, and the arc-shaped convex plates are evenly installed axially on the inner wall of the arc-shaped baffle. There are gaps between the arc-shaped convex plates, and these gaps correspond to the crushing ring cutters. A fixing strip is fixedly installed at the bottom of the fixing plate, and an arc-shaped shovel plate is fixedly installed at the bottom of the fixing strip. Through the cooperation of the arc-shaped shovel plate and the side pad, during the rotation of the cutter shaft cylinder and the crushing ring cutters, the arc-shaped shovel plate cleans between the crushing ring cutters, preventing plastic from getting stuck between them and affecting the crushing effect. Simultaneously, it utilizes… The side pads utilize the rubber material properties to contact the protrusions of the crushing ring cutter, cleaning the plastic at the protrusions and preventing it from adhering to the cutter's cutting position under shearing force after shearing, thus avoiding obstruction and affecting subsequent shearing. The arc-shaped shovel plates are evenly installed axially at the bottom of the fixing strip, and are located below the cutter shaft cylinder on the side away from the side baffle. The arc-shaped shovel plates are located between the crushing ring cutters, and slots are provided on the bottom of both sides of the arc-shaped shovel plates. Side pads, made of rubber, are fixedly installed in the slots of the arc-shaped shovel plates.

[0013] Preferably, the screening mechanism includes a chute frame, a screening bin slidably mounted on the inner wall of the chute frame, a cylinder output end fixedly connected to the outer side of the screening bin, a baffle frame fixedly mounted on the top of the screening bin, the baffle frame being located outside the discharge chute, the bottom of the inner wall of the screening bin being inclined, and a rectangular groove plate fixedly mounted on the inner wall of the screening bin, the rectangular groove plate being inclinedly mounted on the inner wall of the screening bin, and a rectangular groove being formed on the top of the rectangular groove plate, with a fixing rod fixedly mounted at the rectangular groove of the rectangular groove plate. The fixing rods are evenly installed at the rectangular grooves of the rectangular groove plate. Through the cooperation between the rectangular groove plate and the fixing rods, the arc-shaped gap between the fixing rods allows qualified particles to pass smoothly through the gap after shearing and crushing. At the same time, the baffle plate cooperates with the baffle frame to block the falling plastic and unqualified plastic particles during screening, causing plastic particles to splash. There are gaps between the fixing rods. A baffle plate is fixedly installed on the outer side of the screening bin away from the cylinder. The bottom of the baffle plate is in contact with the top of the rectangular groove plate.

[0014] This invention provides a crushing and granulation device for recycling waste plastics that prevents material jamming. It has the following beneficial effects:

[0015] I. This anti-jamming waste plastic recycling crushing and granulation equipment uses a partition block in conjunction with the crushing ring cutter and side baffle to block the waste plastic between the crushing ring cutter. This prevents the plastic from getting stuck in the non-shearing crushing position between the cutter shaft cylinder and the side baffle under the shearing force, thus avoiding jamming and affecting the shearing and crushing of waste plastic. At the same time, the partition block restricts the waste plastic at the arc groove position of the side baffle, so that the volume of waste plastic being sheared by the cutter during shearing and crushing is avoided. This prevents large-volume plastic from being moved, which could cause jamming and result in larger particle sizes during shearing and crushing, thus reducing the crushing effect.

[0016] II. This anti-jamming waste plastic recycling crushing and granulation equipment uses the conical surface of the side baffle plate and the inclined surface of the top of the side baffle plate to guide the plastic when it is fed in, so that the plastic can smoothly reach the shearing and crushing position. At the same time, the side baffle plate restricts the plastic at both ends of the crushing chamber to prevent the plastic from entering the non-crushing area at both ends and getting stuck at both ends when rotating, which would affect the rotation of the crushing blades. Meanwhile, the fixed end plate restricts the rotation center position of the cutter shaft cylinder during shearing and crushing to prevent it from shifting under the shearing reaction force and causing greater wear on the blades.

[0017] Third, this anti-jamming waste plastic recycling crushing and granulation equipment uses an arc baffle and an arc convex plate in combination. The inclined surface at the top of the arc baffle guides the introduced plastic while the arc convex plate tightly fits between the crushing ring cutters and the outside of the cutter shaft cylinder, sealing the gaps between the side baffles. This allows the introduced plastic to smoothly enter the crushing position under the rotation of the crushing ring cutters, avoiding the phenomenon of material accumulation in the crushing chamber caused by the introduced plastic failing to enter the crushing position.

[0018] IV. This anti-jamming waste plastic recycling crushing and granulation equipment uses an arc shovel plate and a side pad plate in conjunction. During the rotation of the cutter shaft cylinder and the crushing ring cutter, the arc shovel plate cleans between the crushing ring cutters, preventing plastic from getting stuck between them and affecting the crushing effect. At the same time, the rubber material of the side pad plate makes it contact the protrusions of the crushing ring cutter, cleaning the plastic at the protrusions. This prevents the plastic from adhering to the cutter cutter's shearing position under the shearing force after shearing and crushing, thus avoiding the inability to be smoothly discharged and affecting subsequent shearing and crushing.

[0019] 5. This anti-jamming waste plastic recycling crushing and granulation equipment uses a rectangular groove plate and a fixed rod in combination. The arc-shaped gap between the fixed rods allows qualified particles to pass smoothly through the gap after shearing and crushing. At the same time, the baffle plate and the baffle frame work together to block the falling plastic and unqualified plastic particles during screening, causing plastic particles to splash.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] First embodiment, such as Figures 1 to 5 As shown, the present invention provides a technical solution:

[0032] A waste plastic recycling crushing and granulation device with anti-jamming features, comprising:

[0033] The crushing chamber 1 has a bottom support plate 4 fixedly installed at its bottom, and the upper and lower sides of the crushing chamber 1 are equipped with a feed chute 5 and a discharge chute 10.

[0034] Material guiding mechanism 2 is installed inside crushing chamber 1;

[0035] Screening mechanism 3 is installed inside the bottom support plate 4. A cylinder 6 is fixedly installed on the outside of the bottom support plate 4. The output end of the cylinder 6 passes through the bottom support plate 4 and extends into it. The output end of the cylinder 6 is fixedly connected to the outside of the screening mechanism 3.

[0036] A motor 7 is fixedly installed on the outside of the crushing chamber 1, and a drive shaft 9 is rotatably installed on the inner wall of the crushing chamber 1. One end of the drive shaft 9 is fixedly connected to the output end of the motor 7 via a coupling. A cutter shaft cylinder 12 is fixedly installed on the outside of the drive shaft 9, and a crushing ring cutter 14 is fixedly installed on the outside of the cutter shaft cylinder 12. Protrusions are evenly arranged on the outside of the crushing ring cutter 14. When shearing and crushing waste plastic, the waste plastic introduced into the crushing chamber 1 is blocked and guided by the material guiding mechanism 2. With the rotation of the crushing ring cutter 14, the waste plastic enters the position where the side baffle 13 contacts the crushing ring cutter 14. Utilizing the arc groove of the side baffle 13 and the protrusions of the crushing ring cutter 14, when the protrusions of the crushing ring cutter 14 enter the arc groove of the side baffle 13 from above during rotation, the protrusions drive the plastic, causing a portion of the plastic to be sheared by the intersection of the protrusions and the side baffle 13. The cutting force breaks the plastic into small pieces. The crushing ring cutters 14 are evenly installed on the outside of the cutter shaft cylinder 12. A side baffle 13 is fixedly installed on the inner wall of the crushing chamber 1 away from the material guiding mechanism 2. The side baffle 13 has evenly opened arc grooves on the side near the cutter shaft cylinder 12, and the arc grooves correspond one-to-one with the crushing ring cutters 14. During the shearing process, the plastic is restricted by the contact between the separator block 15 and the cutter shaft cylinder 12. The separator block 15 is located between the crushing ring cutters 14, which prevents the plastic from entering the gap between the cutter shaft cylinder 12 and the side baffle 13. The separator block 15 is fixedly installed on the side of the side baffle 13 near the cutter shaft cylinder 12. The side of the separator block 15 near the cutter shaft cylinder 12 is in close contact with the outside of the cutter shaft cylinder 12. The top of the separator block 15 is higher than the top of the side baffle 13, and the top of the side baffle 13 is a slope that slopes downward toward the cutter shaft cylinder 12.

[0037] Fixed end plates 11 are fixedly installed at both ends of the inner wall of the crushing chamber 1. The opposite surfaces of the fixed end plates 11 are provided with annular protrusions. Both ends of the cutter shaft cylinder 12 are provided with annular grooves. The annular grooves of the cutter shaft cylinder 12 are rotatably adapted to the annular protrusions of the fixed end plates 11. During rotational shearing, the fixed end plates 11 cooperate with the side baffles 8 to restrict the cutter shaft cylinder 12. When the cutter shaft cylinder 12 is subjected to the reaction force of shearing, the fixed end plates 11 support the cutter shaft cylinder 12. Side baffles 8 are fixedly installed at both ends of the inner wall of the crushing chamber 1. The side baffles 8 are located directly above the fixed end plates 11, and the edge of the opposite surface of the side baffles 8 is a conical surface.

[0038] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 6 to 7As shown, the material guiding mechanism 2 includes a fixed plate 22, which is fixedly installed on the inner wall of the crushing chamber 1 away from the side baffle 13. An arc baffle 21 is fixedly installed on the top of the fixed plate 22. The top of the arc baffle 21 is an inclined surface that slopes from top to bottom towards the side baffle 13. The arc baffle 21 guides the introduced plastic. After the plastic is introduced, it is guided by the inclined surface of the arc baffle 21 towards the side baffle 13. At the same time, the arc baffle 21 cooperates with the arc convex plate 24 to block the side of the cutter shaft cylinder 12 away from the side baffle 13, preventing the plastic from entering the side away from the side baffle 13. The fixed plate 22 has grooves evenly opened on the side near the cutter shaft cylinder 12, and the grooves of the fixed plate 22 correspond one-to-one with the crushing ring cutter 14. The outer side of the arc baffle 21 is tightly fitted with the inner wall of the crushing chamber 1, and the inner wall of the arc baffle 21 is fixedly installed with the arc convex plate 24.

[0039] The side of the arc-shaped convex plate 24 away from the arc-shaped baffle 21 is tightly fitted to the outer side of the cutter shaft cylinder 12, and the arc-shaped convex plate 24 is evenly installed axially on the inner wall of the arc-shaped baffle 21. There are gaps between the arc-shaped convex plates 24, and the gaps between the arc-shaped convex plates 24 correspond to the crushing ring cutter 14. A fixing strip 25 is fixedly installed at the bottom of the fixing plate 22, and an arc-shaped shovel plate 23 is fixedly installed at the bottom of the fixing strip 25. The arc-shaped shovel plate 23 is evenly installed axially at the bottom of the fixing strip 25. After shearing, the arc-shaped shovel plate 23 cooperates with the side pad plate 26 to utilize the arc-shaped shovel plate 23 between the crushing ring cutters 14. The side pad 26 utilizes the characteristics of rubber material to allow the arc shovel 23 to clean the plastic between the crushing ring cutters 14. At the same time, the side pad 26 cleans the plastic at the protrusion position when the crushing ring cutter 14 rotates, so that the sheared plastic falls smoothly and is discharged from the discharge chute 10. The arc shovel 23 is located below the cutter shaft cylinder 12 on the side away from the side baffle 13. The arc shovel 23 is located between the crushing ring cutters 14, and the bottom of both sides of the arc shovel 23 is provided with a slot. The side pad 26 is fixedly installed at the slot of the arc shovel 23. The side pad 26 is made of rubber material.

[0040] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 8 to 9As shown, the screening mechanism 3 includes a chute frame 31, with a screening bin 34 slidably mounted on the inner wall of the chute frame 31. The output end of the cylinder 6 is fixedly connected to the outer side of the screening bin 34. A baffle frame 32 is fixedly mounted on the top of the screening bin 34, located outside the discharge chute 10. The bottom of the inner wall of the screening bin 34 is inclined, and a rectangular groove plate 35 is fixedly mounted on the inner wall of the screening bin 34. After the sheared and crushed plastic is discharged from the discharge chute 10, it falls smoothly into the interior of the screening bin 34 under the obstruction of the baffle frame 32. At the same time, the plastic falls on the top of the rectangular groove plate 35. Simultaneously, the cylinder 6 drives the screening bin 34 to reciprocate on the inner wall of the chute frame 31, causing the plastic on the top of the rectangular groove plate 35 to shake, allowing qualified plastic particles to pass through the gap between the fixed rods 36 and fall to the bottom of the inner wall of the screening bin 34. The rectangular groove plate 35 is installed at an incline on the bottom of the inner wall of the screening bin 34. The rectangular groove plate 35 is installed at an incline on the inner wall of the screening bin 34, and a rectangular groove is opened on the top of the rectangular groove plate 35. A fixing rod 36 is fixedly installed at the rectangular groove of the rectangular groove plate 35. The fixing rods 36 are evenly installed at the rectangular groove of the rectangular groove plate 35, and there are gaps between the fixing rods 36. During the shaking process, qualified plastic particles pass through the gaps between the fixing rods 36 and slide out through the incline at the bottom of the screening bin 34. Unqualified plastic particles slide close to the baffle plate 33 on the top of the rectangular groove plate 35 and are then blocked by the baffle plate 33, so that the unqualified plastic particles are away from the bottom of the discharge chute. A baffle plate 33 is fixedly installed on the outer side of the screening bin 34 away from the cylinder 6. The bottom of the baffle plate 33 is in contact with the top of the rectangular groove plate 35.

[0041] In operation, workers feed the waste plastic to be crushed into the crushing chamber 1 through the feed chute 5. At the same time, they start the motor 7 and the cylinder 6, which drives the transmission shaft 9. The transmission shaft 9 drives the cutter shaft cylinder 12 to rotate at high speed on the inner wall of the crushing chamber 1. During the rotation of the cutter shaft cylinder 12, the crushing ring cutter 14 is driven to work. The material guiding mechanism 2, together with the crushing ring cutter 14 and the side baffle 13, shears and crushes the plastic during the rotation, breaking the waste plastic into fine particles. After the crushed waste plastic is discharged from the discharge chute 10, it falls into the screening mechanism 3. The cylinder 6 drives the screening mechanism 3 to run and screen the falling plastic particles.

[0042] When shearing and crushing waste plastic, the feeding mechanism 2 blocks and guides the waste plastic entering the crushing chamber 1. Combined with the rotation of the crushing ring cutter 14, the waste plastic enters the contact position between the side baffle 13 and the crushing ring cutter 14. Utilizing the arc groove of the side baffle 13 and the protrusion of the crushing ring cutter 14, as the protrusion of the crushing ring cutter 14 rotates and enters the arc groove of the side baffle 13 from above, the protrusion pulls the plastic, causing a portion of the plastic to be sheared by the interlacing movement between the protrusion and the side baffle 13. The force causes the plastic to break and separate into small pieces. During the shearing process, the plastic is restricted by the contact between the separator 15 and the cutter shaft cylinder 12, and the separator 15 is located between the crushing ring cutters 14, preventing the plastic from entering the gap between the cutter shaft cylinder 12 and the side baffle 13. At the same time, when rotating and shearing, the cutter shaft cylinder 12 is restricted by the cooperation between the fixed end plate 11 and the side baffle 8. When the cutter shaft cylinder 12 is subjected to the reaction force of shearing, the fixed end plate 11 supports the cutter shaft cylinder 12.

[0043] In the feeding mechanism 2, the introduced plastic is guided by the arc baffle 21. The inclined surface at the top of the arc baffle 21 guides the plastic to the side baffle 13 after it is introduced. At the same time, the arc baffle 21 cooperates with the arc protrusion plate 24 to block the side of the cutter shaft cylinder 12 away from the side baffle 13, preventing the plastic from entering the side away from the side baffle 13. After shearing, the arc shovel plate 23 cooperates with the side pad plate 26. The arc shovel plate 23 is positioned between the crushing ring cutters 14, and the side pad plate 26 is made of rubber. The arc shovel plate 23 cleans the plastic between the crushing ring cutters 14. At the same time, the side pad plate 26 cleans the plastic at the protrusion position when the crushing ring cutter 14 rotates, so that the sheared plastic falls smoothly and is discharged from the discharge chute 10.

[0044] In the screening mechanism 3, after the plastic is sheared and crushed, it is discharged from the discharge chute 10 and falls smoothly into the screening bin 34 under the obstruction of the baffle frame 32. At the same time, the plastic falls on the top of the rectangular groove plate 35. Simultaneously, the cylinder 6 drives the screening bin 34 to reciprocate on the inner wall of the sliding frame 31, causing the plastic on the top of the rectangular groove plate 35 to shake. This allows qualified plastic particles to pass through the gap between the fixed rods 36 and fall to the bottom of the inner wall of the screening bin 34. Utilizing the inclined rectangular groove plate 35 and the inclined surface at the bottom of the inner wall of the screening bin 34, during the shaking process, qualified plastic particles pass through the gap between the fixed rods 36 and slide out through the inclined surface at the bottom of the screening bin 34. Unqualified plastic particles slide close to the baffle plate 33 on the top of the rectangular groove plate 35 and are then blocked by the baffle plate 33, causing the unqualified plastic particles to move away from the bottom of the discharge chute.
