Description
Technical Field
[0001] This utility model relates to the technical field of waste plastic recycling and processing equipment, and in particular to a mixed waste plastic crushing equipment. Background Technology
[0002] With the rapid development of the plastics industry, the amount of waste plastic generated has been increasing year by year. Waste plastic recycling has become an important way to alleviate resource shortages and environmental pollution. In the mixed waste plastic recycling process, crushing is the core pre-processing step. Irregularly shaped waste plastics such as blocks and flakes need to be crushed into uniformly sized fragments, which are then transported to temporary storage tanks by conveying equipment to lay the foundation for subsequent granulation, remolding and other deep processing steps. In existing equipment, the crushing outlet and conveyor belt are mostly directly connected without a buffer transition structure. When the crushed material falls from the outlet, it is subject to a large impact due to gravity, and is easily splashed outside the conveyor belt, with a splash rate as high as 25%-30%. In addition, the connection between the conveyor belt and the temporary storage tank is mostly a fixed structure, which cannot adjust the angle according to the actual height of the temporary storage tank. When the height of the temporary storage tank does not match the height of the conveyor belt outlet, the crushed material is prone to deviate from the feed inlet of the temporary storage tank during the fall, resulting in leakage, further reducing the material utilization rate. Moreover, if the spilled crushed material is not cleaned up in time, it may also pollute the workshop environment. Utility Model Content

[0021] Please see Figure 1-5 This utility model provides a technical solution: a mixed waste plastic crushing equipment, including a crusher 1, an anti-slip and anti-accumulation conveyor belt module, and a precise connection transition module. The anti-slip and anti-accumulation conveyor belt module is set at the discharge position behind the crusher 1, and the precise connection transition module is set at the discharge port 2 of the crusher 1 and the discharge port of the conveyor belt. The anti-slip and anti-accumulation conveyor belt module includes a speed controller 5, a high-friction anti-slip conveyor belt 6, a frequency converter motor 17, and detachable sidewalls 19; The precise connection transition module includes an arc-shaped material guide buffer plate 3, a material discharge plate 11, a scraper plate 13, a leak-proof skirt 18, an adjustable guide plate 21, an adjusting block 22, and an adjusting bolt 23; The crusher 1 is equipped with a discharge port 2. A buffer plate connecting block 4 is fixedly connected below the discharge port 2. An arc-shaped guide buffer plate 3 is fixedly connected to the buffer plate connecting block 4. The arc-shaped guide buffer plate 3 allows the crushed material to slide smoothly along the arc surface, reducing the impact force. The buffer plate connecting block 4 is fixed to the discharge port 2 by bolts to ensure the installation error of the arc-shaped guide buffer plate 3 and avoid the offset and leakage caused by the loose connection of the existing equipment. The conveyor support 12 is set at the bottom front of the crusher 1. Four conveyor support frames 15 are fixedly connected to the conveyor support 12. The conveyor support frames 15 are fixedly connected to the feeding conveyor 14. Four roller fixing plates 7 are fixedly connected to the feeding conveyor 14. The four roller fixing plates 7 are set in pairs at the front and rear ends of the feeding conveyor 14.

The high-friction anti-slip conveyor belt 6 is fixedly connected to the drive roller 8 and the driven roller 9. The high-friction anti-slip conveyor belt 6 is made of rubber + polyester fiber composite material, which takes into account both wear resistance and tensile strength. Its service life is longer than that of the existing ordinary conveyor belt, reducing the cost of frequent replacement. The drive roller 8 is fixedly connected to the left side of the coupling 16. The output end of the variable frequency motor 17 is fixedly connected to the coupling 16. The bottom of the variable frequency motor 17 is fixedly connected to the bracket, which is fixedly connected to the roller fixing plate 7. The front left side of the crusher 1 is fixedly connected to the speed controller 5. The variable frequency motor 17 works with the speed controller 5 to achieve stepless speed regulation. It can be flexibly adapted according to the size of the feed inlet of the temporary storage tank and the amount of crushed material, avoiding spillage or accumulation caused by speed mismatch of the existing equipment. The speed controller 5 is integrated at the front end of the crusher 1. The operating distance is ergonomic, eliminating the need to bend over or get close to the conveyor belt for adjustment as required by existing equipment, thus improving the ease of operation. The feeding conveyor table 14 is provided with a slot, and the detachable side rail 19 is movably connected in the slot. The bottom of the detachable side rail 19 is provided with a corresponding locking block. The detachable side rail 19 is externally fixedly connected with a side rail buckle 20. The bottom of the side rail buckle 20 is fixedly connected to the feeding conveyor table 14. The leak-proof skirt 18 is fixedly connected inside the detachable side rail 19. The leak-proof skirt 18 is made of silicone material and fits tightly with the surface of the high-friction anti-slip conveyor belt 6 to eliminate gaps. The elastic material can adapt to slight deviation of the high-friction anti-slip conveyor belt, avoiding material leakage caused by the rigid gaps of existing equipment, and is not easily worn; The feeding plate 11 is located below the tail end of the high-friction anti-slip conveyor belt 6. The scraper 13 is fixedly connected to the feeding plate 11 and connects to the bottom of the high-friction anti-slip conveyor belt 6 without affecting its movement. The adjustable guide plate 21 is movably connected to the feeding plate 11. The adjusting bolt 23 is rotatably connected to the adjusting block 22. The adjusting block 22 is fixedly connected to both sides of the adjustable guide plate 21 on the feeding plate 11. The front end of the adjusting bolt 23 is rotatably connected to the adjustable guide plate 21. A collection box 10 is provided at the bottom of the feeding plate 11.
[0022] Working principle: The operator puts high-toughness block PE into the feed inlet of crusher 1. After crusher 1 is started, the internal blade group shears and crushes the block PE. The crushed PE fragments are discharged from the preset discharge port 2 of the equipment under the power inside crusher 1 and enter the subsequent conveying stage. At this time, the buffer plate connecting block 4 fixed below the discharge port 2 plays a supporting and transition role, providing stable support for the arc-shaped guide buffer plate 3 and ensuring that the fragment discharge path is continuous. The operator sets the running speed of the high-friction anti-slip conveyor belt 6 by using the speed controller 5 fixed on the left side of the front end of the crusher 1. The speed controller 5 sends a signal to the variable frequency motor 17, which starts and outputs power. The torque is transmitted to the drive roller 8 through the coupling 16. Both the drive roller 8 and the driven roller 9 are rotatably supported on the feeding conveyor table 14 through the roller shaft fixing plate 7, which drives the drive roller 8 to rotate. When the drive roller 8 rotates, it drives the conveyor belt to run through the friction with the high-friction anti-slip conveyor belt 6. At the same time, the driven roller 9 rotates synchronously with the conveyor belt. The PE scrap discharged from the discharge port 2 is gently guided by the arc-shaped guide buffer plate 3 to the surface of the high-friction anti-slip conveyor belt 6—the diamond anti-slip pattern on the surface of the conveyor belt—to prevent the high-toughness PE scrap from slipping or accumulating. The detachable sidewalls 19 on both sides of the feeding conveyor 14 are movably connected by a slot-block structure, and together with the sidewall buckle 20, they form lateral protection to prevent the material from spilling from both sides of the conveyor belt. At the same time, the leak-proof skirt 18 fixed inside the detachable sidewalls 19 fits tightly against the surface of the conveyor belt to eliminate gaps and further prevent the material from leaking out. After the high-friction anti-slip conveyor belt 6 transports the crushed material to the tail end, the crushed material naturally falls onto the discharge plate 11 set below the tail end of the conveyor belt. The operator can adjust the adjusting block 22-adjusting bolt 23 assembly. The adjusting block 22 is fixed on the discharge plate 11, and the front end of the adjusting bolt 23 is rotatably connected to the adjustable guide plate 21. Rotating the adjusting bolt 23 changes the tilt angle of the adjustable guide plate 21, so that the crushed material falls accurately into the feed inlet of the temporary storage tank along the guide plate, realizing the seamless connection between the conveyor belt and the temporary storage tank. During the operation of the high-friction anti-slip conveyor belt 6, the scraper 13 fixed on the feed plate 11 is always in close contact with the bottom of the conveyor belt, scraping off the residual PE fragments on the surface of the conveyor belt in real time, so as to avoid the residual fragments from sticking together and causing a decrease in conveying efficiency or contamination of subsequent materials. The residual debris scraped off by the scraper 13 falls naturally into the collection box 10 located at the bottom of the feed plate 11. Operators can periodically remove the collection box 10 to pour the residual debris back onto the conveyor belt or recycle it separately, achieving zero material waste.
[0023] Structural Description: Crusher 1: As the core crushing component of the equipment, it is equipped with a discharge port 2 for feeding high-toughness blocky PE and shearing and crushing it through the internal blade assembly. The crushed material is discharged from the discharge port 2. At the same time, the speed controller 5 is fixedly connected to the front left side of the crusher 1, and an anti-slip and anti-accumulation conveyor belt module is set at the rear discharge position. A conveyor platform support 12 is set at the front bottom. The crushing function and the installation foundation of each module are integrated to ensure that the crushing, control and conveying modules form a unified whole, avoid the connection misalignment caused by the separate layout of the equipment, and provide stable initial crushing conditions for subsequent material conveying and connection. Discharge port 2: Located at the discharge end of crusher 1, with buffer plate connecting block 4 fixedly connected below. It is used to receive PE fragments after being crushed by the internal blade assembly of crusher 1 and guide the fragments to the arc-shaped guide buffer plate 3 on the buffer plate connecting block 4. It serves as a transition channel for the fragments from the crushing stage to the conveying stage. Through the fixed connection with the buffer plate connecting block 4, it ensures that the fragment discharge path is fixed, avoids splashing caused by the fragments falling directly, and provides a precise starting point for the fragment input to the arc-shaped guide buffer plate 3. Arc-shaped guide buffer plate 3: Fixedly connected to the buffer plate connecting block 4, it has an arc-shaped curved surface structure and is used to receive the broken material discharged from the discharge port 2, so that the broken material slides smoothly down the arc-shaped curved surface to the surface of the high-friction anti-slip conveyor belt 6. The arc-shaped curved surface design can reduce the impact force of the falling broken material and avoid the splashing caused by the broken material directly hitting the conveyor belt. At the same time, by fixing it to the buffer plate connecting block 4, it ensures that the installation error is small and avoids the broken material deviation and leakage caused by loose connection. Buffer plate connecting block 4: It is fixedly connected below the discharge port 2 and the top is fixedly connected to the arc-shaped guide buffer plate 3. It is tightly fixed to the discharge port 2 by bolts. It serves as the connection medium between the discharge port 2 and the arc-shaped guide buffer plate 3. It provides stable support for the arc-shaped guide buffer plate 3 and ensures a firm overall connection by bolt fixing. It avoids the displacement of the arc-shaped guide buffer plate 3 due to loose connection in the existing equipment and ensures the continuity of the crushed material guiding path. Speed controller 5: Fixedly connected to the left side of the front end of crusher 1, electrically connected to variable frequency motor 17, used to receive speed setting instructions from the operator and send signals to variable frequency motor 17 to adjust the speed. Integrated at the front end of crusher 1 and with an ergonomic operating distance, it eliminates the need for operators to bend over or approach the conveyor belt for adjustment. It can achieve stepless speed regulation and can flexibly adapt the speed according to the size of the feed inlet of the temporary storage tank and the amount of crushed material, avoiding spillage or accumulation caused by speed mismatch. High-friction anti-slip conveyor belt 6: Fixedly connected to the driving roller 8 and the driven roller 9, it is made of rubber + polyester fiber composite material and has diamond anti-slip texture on the surface. It is used to receive the broken material guided by the arc-shaped guide buffer plate 3 and convey it to the unloading plate 11 at the tail end. The rubber + polyester fiber composite material takes into account both wear resistance and tensile strength, and its service life is longer than that of existing ordinary conveyor belts, reducing the cost of frequent replacement. The diamond anti-slip texture on the surface increases the friction with the broken material and prevents the high-toughness PE broken material from slipping or accumulating. Roller fixing plates 7: There are four in total, all of which are fixedly connected to the feeding conveyor table 14. They are set in pairs at the front and rear ends of the feeding conveyor table 14. The two sets of roller fixing plates 7 at the front end are rotatably connected to the driving roller 8, and the two sets of roller fixing plates 7 at the rear end are rotatably connected to the driven roller 9. They provide stable rotational support for the driving roller 8 and the driven roller 9, ensuring that there is no deviation when the rollers rotate, thereby ensuring the smooth operation of the high-friction anti-slip conveyor belt 6. They are set in groups at the front and rear ends of the feeding conveyor table 14 so that the roller spacing is adapted to the length of the conveyor belt, avoiding the conveyor belt from being slack or overly tense. Active roller 8: Rotatably connected between two sets of roller fixing plates 7 at the front end of the feeding conveyor table 14, and fixedly connected to the left side by a coupling 16. The coupling 16 receives the torque transmitted by the variable frequency motor 17 and drives the high friction anti-slip conveyor belt 6 to rotate. As the core of the power transmission of the conveyor belt, it converts the motor power into the conveying power of the conveyor belt through linkage with the variable frequency motor 17. The rotatable connection method ensures smooth operation, reduces friction loss, and ensures stable operation of the conveyor belt. Driven roller 9: Rotatably connected between two sets of roller fixing plates 7 at the rear end of the feeding conveyor table 14, it rotates synchronously with the operation of the high friction anti-slip conveyor belt 6, and cooperates with the active roller 8 to form tension support for the conveyor belt, preventing the conveyor belt from sagging due to gravity during the conveying of crushed materials. The synchronous rotation design reduces the friction between the conveyor belt and the roller, extends the service life of the conveyor belt, and ensures uniform conveying speed. Collection box 10: Located at the bottom of the feed plate 11, it is used to receive residual debris from the conveyor belt scraped down by the scraper plate 13. It can collect residual debris and recycle it, avoiding waste caused by debris falling directly to the ground. It can be removed and emptied periodically, reducing the frequency of manual cleaning and lowering operating costs. Discharge plate 11: Located below the tail end of the high-friction anti-slip conveyor belt 6, with a scraper plate 13 fixedly connected to the top, an adjustable guide plate 21 movably connected to the side, and a collection box 10 at the bottom to receive the broken material falling from the tail end of the conveyor belt and guide it to the adjustable guide plate 21. As a transition structure between the conveyor belt and the adjustable guide plate 21, it ensures that the broken material falls smoothly from the conveyor belt into the guide plate, avoiding spillage caused by the direct fall of the broken material. At the same time, it provides an installation base for the scraper plate 13 and the adjustable guide plate 21, realizing the integration of conveying-cleaning-guiding functions. Conveyor platform bracket 12: It is set at the bottom in front of the crusher 1, and four conveyor platform support frames 15 are fixedly connected to the top. It provides stable bottom support for the conveyor platform support frames 15, and forms a related support structure between the feeding conveyor platform 14 and the crusher 1. It avoids shaking or displacement of the feeding conveyor platform 14 due to independent placement, and ensures the connection accuracy between the conveying module and the crushing module. Scraper 13: Fixedly connected to the feed plate 11, with the top end connected to the bottom of the high-friction anti-slip conveyor belt 6 without affecting the movement of the conveyor belt. It is used to scrape off the PE debris remaining on the surface of the conveyor belt in real time, clean the residual debris on the conveyor belt in real time, and avoid the decline in conveying efficiency or subsequent debris contamination caused by the adhesion of residual debris. It is tightly connected to the bottom of the conveyor belt without affecting the movement, ensuring the cleaning effect without interfering with normal conveying. Feeding conveyor 14: It is fixedly connected to the top of the four conveyor support frames 15. The upper surface is fixedly connected to four roller fixing plates 7. The side is provided with a slot for movably connecting the detachable side guard 19. As the load-bearing base of the conveying module, the integrated installation structure of roller fixing plates 7 and detachable side guard 19 makes the various parts of the conveying module form a unified whole. The fixed connection with the conveyor support frame 15 ensures the stability of the overall structure and avoids shaking during the conveying process. Conveyor support frame 15: There are four in total, all of which are fixedly connected to the top of the conveyor support frame 12. The top of the four support frames are fixedly connected to the feeding conveyor 14. The even distribution of the four support frames provides balanced support for the feeding conveyor 14, ensuring that the feeding conveyor 14 remains horizontal and avoiding the conveyor belt tilting due to uneven force. The height can be adjusted according to the needs to adapt to the conveying height requirements in different scenarios. Coupling 16: It is fixedly connected between the left side of the drive roller 8 and the output end of the variable frequency motor 17. It is used to transmit the torque of the variable frequency motor 17 to the drive roller 8, realize the flexible connection between the motor and the roller, reduce the impact load on the roller during motor start-up, ensure accurate torque transmission, avoid power loss, and ensure that the conveyor belt speed is synchronized with the motor speed. Variable frequency motor 17: The bottom is fixedly connected to the roller fixing plate 7 by a bracket, and the output end is fixedly connected to the coupling 16. It receives the signal of the speed controller 5 and adjusts the speed to provide power to the active roller 8. It can achieve stepless speed regulation according to the instructions of the speed controller 5 to adapt to different conveying needs. The bottom bracket is fixed to the roller fixing plate 7 to ensure that the motor has no vibration or deviation during operation, and to reduce noise and component wear. Leak-proof skirt 18: It is fixedly connected to the inside of the detachable side guard 19. It is made of silicone material and fits tightly with the surface of the high-friction anti-slip conveyor belt 6. The silicone material is elastic and can adapt to the slight deviation of the conveyor belt. It eliminates the gap between the detachable side guard 19 and the conveyor belt. The tight fit design prevents the leakage of broken materials from the side and improves the leakage prevention effect of the conveyor. Detachable side guard 19: It is movably connected to the slot of the feeding conveyor table 14 through the bottom locking block, and externally fixed to the side guard buckle 20. It is used to form lateral protection on both sides of the high friction anti-slip conveyor belt 6.
