Description

Technical Field

[0001] The invention relates to the technical field of waste plastic recycling, and in particular to processing equipment for recycling waste plastic to prepare cable material particles. Background Art

[0002] In the industrial processing of recycling waste plastics to prepare cable material particles, traditional equipment generally has problems such as high energy consumption, poor particle uniformity and insufficient continuous operation capacity. In the existing technology, plastic crushing mostly adopts a single-stage high-speed crushing structure. Large pieces of material directly enter the crushing link, which can easily lead to a sudden increase in tool load, not only in energy efficiency, but also accelerate tool wear. Although some equipment has introduced a pre-crushing structure, the power separation design of the tearing and crushing units increases the complexity of the transmission, and the uneven distribution of materials in the crushing box can easily cause local overload, affecting the screening effect. In addition, the crushed plastic scraps often clump due to electrostatic adsorption or humidity. The traditional vibrating conveying mechanism lacks a targeted loose design, which leads to repeated processing in the subsequent grinding process, increasing energy consumption while reducing the qualified rate of finished products.

[0003] In the fine grinding stage, conventional equipment mostly uses fixed grinding discs or single-direction extrusion structures, which result in insufficient friction on the particle surface and make it difficult to meet the surface finish requirements of cable materials. If the heat generated by the continuous friction between plastic and metal parts during the grinding process cannot be dissipated in time, it will cause local melting and adhesion of the particles, especially when processing thermoplastic materials. Although air cooling has been introduced in the existing technology, the airflow path and the grinding movement have poor coordination, the heat dissipation efficiency is limited, and the problem of residual material blockage in the grinding area cannot be solved simultaneously. In addition, independent systems driven by multiple power sources (such as separate motors for crushing, conveying, and grinding) lead to redundant equipment structure, cumulative energy consumption, and high maintenance costs, which restrict the feasibility of large-scale production. Summary of the Invention

The device solves the problems of uneven crushing, particle adhesion, high energy consumption, etc. existing in traditional plastic recycling equipment through the integration of multiple technologies such as mechanical vibration, spiral pushing, screening and grinding, and airflow assistance.

[0013] The present invention provides a processing device for recycling waste plastics to prepare cable material particles, which has the following beneficial effects:

[0014] This device utilizes a two-stage crushing structure consisting of a tearing box (including tearing rollers) and a crushing box (including crushing blades). This tiered process of initial tearing followed by spiral crushing significantly reduces the energy consumption of directly crushing bulk plastic. The tearing rollers pre-crush the material, reducing the load on the crushing blades. The crushing blades' spiral blades simultaneously push the material toward the center during the cutting process. Combined with the dynamic screening mechanism of the screen, this creates a circular crushing path, ensuring uniform crushing while avoiding energy waste caused by repeated processing. A single servo motor drives the crushing blades, the vibrating mechanism of the receiving tray, and the exhaust fan, effectively achieving multiple functions in one machine.

[0015] The receiving tray's tilted, reciprocating vibration is driven by a cam, pressure arm, and guide slider mechanism. The vibration amplitude is precisely controlled by a spring's elastic return action. During vibration, materials accelerate down the tilted tray, while inertia effectively loosens aggregates and debris, eliminating the material adhesion issues associated with traditional equipment caused by static electricity or moisture.

[0016] The semi-cylindrical grinding protrusions on the inner side of the discharge guide plate and the inner discharge guide plate form a dynamic grinding channel. This reciprocating motion compresses and rubs the crushed material, achieving a surface finish that meets the requirements for cable material production. During the grinding process, the air nozzles in the buffer air box continuously spray air downward, accelerating the passage of particles through the grinding channel while also dissipating heat generated by friction, preventing the plastic from melting and agglomerating due to excessive temperature rise.

The upper end of the buffer air box 1001 is connected to the air pipe 1002, and the other end of the air pipe 1002 is connected to the air outlet pipe of the exhaust fan 11. The exhaust fan 11 rotates with the drive shaft 501 to generate a continuous airflow.

[0050] The following further explains and illustrates the role and function of the specific structures and technical features in the above content:

[0051] The recycling and processing box 1 serves as the main frame of the equipment. A tear box 3, mounted on top, features a flared top (unnumbered) to facilitate the input of large pieces of waste plastic. Two sets of interlocking tear rollers 302 within the tear box 3, driven by independent tear motors 301, provide the initial tearing and crushing of the plastic. The shredded fragments pass through a channel at the bottom of the tear box 3 that connects to the crushing box 7 for the next processing stage. This design reduces subsequent crushing pressure through graded processing and prevents large pieces of material from entering the crushing stage, which could cause equipment jams.

[0052] The crushing box 7 is fixed to the center of the inner cavity of the recycling and processing box 1, with the drive shaft 501 fixedly supported at its left and right ends by end guide plates 5. The drive shaft 501 is driven by a servo motor 6, which drives the rotation of a crushing blade 701 installed horizontally in the crushing box 7 through a coupling. The special design of the crushing blade 701 is reflected in its blade group spirally distributed from both ends to the center (the blade group is not individually numbered). This spiral structure not only achieves cutting and crushing during rotation, but also pushes the material toward the center of the crushing box 7. In conjunction with the curved screen 702 at the bottom, it forms a dynamic screening mechanism: the crushed material that meets the particle size requirements passes through the screen 702 and falls to the receiving tray 8, while the fragments that do not meet the requirements continue to be crushed in a cycle driven by the spiral blades, ensuring uniform crushing.

[0053] The receiving tray 8 is pivotally connected to the bottom of the end guide plate 5 via a rotating shaft (unnumbered). Its tilted, outward design facilitates the sliding of materials. The cam 502 fixed to the drive shaft 501 periodically squeezes the pressure wheel 802, driving the pressure arm 801 to swing up and down about the rotating shaft. The movable bar hole 8011 of the pressure arm 801 slides with the hook pin 1021 on the slider 102. Combined with the vertical guidance of the guide rod 101 and the return thrust of the spring 103, this creates a stable vibration trajectory. This structure causes the receiving tray 8 to produce an inclined, reciprocating vibration. This not only accelerates the movement of materials toward the inner discharge guide plate 9, but also loosens the material by vibrating, preventing the crushed material from accumulating and clumping on the receiving tray 8.

[0054] The inner discharge guide plate 9 is fixedly mounted on the recycling and processing box 1, and its lower end is bent outward and extended to form a guiding slope. The outer discharge guide plate 10 is connected to the guide rod 101 through a slider 102, and moves up and down synchronously with the vibration of the receiving tray 8. A dynamic grinding channel is formed between the semi-cylindrical grinding protrusion 1004 provided on the inner side of the outer discharge guide plate 10 and the inner discharge guide plate 9. The crushed material is squeezed and ground by the reciprocating motion of the outer discharge guide plate 10, and finally particles with a particle size that meets the requirements of the cable material are formed. During the grinding process, the exhaust fan 11 generates an airflow through the synchronous operation of the drive shaft 501, which is transported to the buffer air box 1001 through the air pipe 1002, and is sprayed downward to the grinding channel by the nozzle 1003, realizing three functions: ① Blowing the grinding area to prevent particles from sticking; ② Accelerating the particles to pass through the grinding channel; ③ Assisting in heat dissipation to prevent high-temperature melting of the plastic.

[0055] The fan impeller shaft of exhaust fan 11 is directly connected to the outer end of drive shaft 501. A single servo motor 6 provides triple drive: rotation of pulverizing blade 701, vibration of receiving tray 8, and operation of exhaust fan 11. This design simplifies the transmission structure and reduces energy consumption, while ensuring synchronization of airflow with pulverizing and grinding actions, improving system coordination.

[0056] Controller 2, mounted on the outer wall of recycling chamber 1, centrally controls the operating parameters (such as speed and direction) of shredding motor 301 and servo motor 6, and monitors the equipment's vibration frequency and airflow pressure. By adjusting the speed of servo motor 6, the shredding intensity, vibration amplitude, and airflow intensity can be simultaneously varied, achieving a dynamic balance between processing efficiency and product quality.

[0057] Working principle:

[0058] Before operation, check the connection status of all components within the recycling and processing chamber 1 and confirm that the tearing chamber 3, crushing chamber 7, and discharge guide system are unobstructed. Use controller 2 to set the speed of the tearing motor 301, the drive frequency of the servo motor 6, and the operating mode of the exhaust fan 11. Adjust the speed of the servo motor 6 to match the spiral force of the crushing blade 701 according to the type of plastic (e.g., PE, PVC). Also, adjust the vibration amplitude parameters of the receiving tray 8 to ensure a balance between material conveying and grinding efficiency.

[0059] Large pieces of waste plastic are fed into the tearing box 3 through the flared opening at the top. Inside, two sets of interlocking tearing rollers 302, driven by a tearing motor 301, rotate synchronously in opposite directions, initially tearing and crushing the plastic. The gap between the tearing rollers 302 is dynamically adjusted by the controller 2 based on the hardness of the material, ensuring uniform fragment size. The torn plastic fragments then naturally fall through the bottom channel into the crushing box 7.

[0060] The servo motor 6 drives the driving shaft 501 to rotate the crushing knife 701, and the two end spiral distribution blade groups perform secondary crushing on the fragments. The spiral blade gathers the materials to the middle part of the crushing box 7 during the cutting process, and the bottom arc screen 702 performs real-time screening on the crushed materials: the crushed materials meeting the particle size requirements fall through the screen 702 into the receiving tray 8, and the substandard fragments are circulated and crushed under the pushing of the spiral blade.

[0061] The receiving tray 8 is driven to produce inclined reciprocating vibration under the driving of the cam 502 and the pressure arm 801: the cam 502 periodically extrudes the pressure wheel 802 with the rotation of the driving shaft 501, the pressure arm 801 is slidably connected with the hanging pin 1021 through the movable strip hole 8011, and a stable vibration track is formed under the constraint of the guide rod 101 and the spring 103. The vibration effect makes the crushed materials accelerate along the inclined receiving tray 8 to the discharge inner guide plate 9, and loosens the agglomerated materials. The crushed materials enter the grinding channel through the bent guide inclined surface at the lower end of the discharge inner guide plate 9, and the discharge outer guide plate 10 moves up and down synchronously with the sliding block 102, and the inner side semicylindrical grinding protrusion 1004 of the discharge outer guide plate 10 forms dynamic extrusion with the discharge inner guide plate 9, so that the crushed materials are ground into particles with the required particle size of the cable material.

[0062] The airflow generated by the air extractor 11 is delivered to the buffer air tank 1001 through the air pipe 1002, and is sprayed downward to the grinding channel by the air jet head 1003. The airflow realizes three functions: blowing the surface of the grinding protrusion 1004 to prevent particle adhesion; accelerating the particles through the grinding channel to improve processing efficiency; and assisting in heat dissipation to prevent the plastic from melting and agglomerating due to friction heating. The final product particles are discharged from the end of the grinding channel and stored in the external collection device.

[0063] After the processing is completed, the feeding is stopped first, and the equipment is idled for 2-3 minutes to ensure that the residual materials are discharged. The tearing motor 301, the servo motor 6 and the air extractor 11 are sequentially turned off through the controller 2. The blockage of the screen 702 is cleaned regularly, the wear degree of the spiral blade of the crushing knife 701 is checked, and the contact surface of the guide rod 101 and the pressure wheel 802 is lubricated to maintain the stability of the vibration mechanism. If it is necessary to replace the shape and specifications of the grinding protrusion 1004, the discharge outer guide plate 10 can be disassembled for modular adjustment to adapt to the production requirements of cable materials with different particle sizes.
