Description

Technical Field

[0001] This invention relates to the technical field of plastic waste recycling, specifically to a plastic particle mixing machine for cable material processing. Background Technology

[0002] In the process of cable material processing, in order to reduce overall costs and promote environmental protection, recycling plastic waste has become an effective solution. After the recycled plastic waste is processed into plastic particles by a granulator, these particles are then mixed by a mixer. However, during the mixing process, plastic particles tend to adhere to the inner wall of the equipment, which not only increases the difficulty of later cleaning, but may also lead to cross-contamination and affect the quality of the next production.

[0003] To overcome the above-mentioned defects, existing technology 1 (Chinese patent CN217047038U, published on July 26, 2022) provides a mixing machine for processing plastic particles that facilitates material feeding. The machine includes a body, a base at the bottom of the body, support rods fixedly connected to both sides of the top of the base, a connecting shaft between the support rods and the body, a cover at the top of the body, a stirring rod movably connected to the bottom of the cover, a first stirring blade fixedly connected to the bottom of the stirring rod, and feeding hoppers on both sides of the body. This mixing machine for processing plastic particles facilitates material feeding by placing the raw material into the feeding hoppers on both sides of the body. Feeding can be achieved by controlling the regulating valve. A scale and a visual strip at one end of the feeding hopper allow for timely observation of the raw material volume. The raw material inside the feeding hopper enters the body through the feeding pipe. This structure not only achieves quantitative and stable feeding but also improves feeding efficiency and solves the problem of inconvenient feeding. The present invention relates to a mixing device for processing plastic particles (Chinese Patent No. CN222727036U, published on April 8, 2025). The device includes a mixing barrel, with a drive motor fixedly installed at the bottom of the mixing barrel to rotate a stirring assembly. A control cabinet electrically connected to the drive motor is located at one end of the mixing barrel. The stirring assembly includes a stirring spindle disposed inside the mixing barrel and stirring rods symmetrically and evenly fixed at both ends of the stirring spindle. This invention uses a snap-fit ​​sliding rod to snap-fit ​​a connecting plate to the stirring spindle, and then uses a snap-fit ​​groove and a snap-fit ​​block to snap-fit ​​a metal scraper to the connecting plate. A fastening threaded rod passes through the fastening threaded grooves at both ends of the snap-fit ​​groove and the snap-fit ​​block to further fix the connecting plate and the metal scraper. The metal scraper can scrape and clean the plastic particles adhering to the inner wall of the mixing barrel when the stirring spindle rotates. The snap-fit ​​sliding rod, fastening threaded rod, and fastening threaded groove facilitate convenient replacement of the metal scraper later.

[0004] While existing technologies use agitators and metal scrapers to treat plastic particles adhering to the inner wall of the equipment, the recycled plastic particles often agglomerate during the mixing process. This agglomeration makes it difficult for the agitators and metal scrapers to mix, thus significantly affecting the uniformity of the mixture and further reducing the overall mixing efficiency.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing plastic particle mixing machine for cable material processing. Therefore, we proposed that the plastic particle mixing machine for cable material processing can effectively solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a plastic particle mixing machine for cable material processing, in order to solve the problem mentioned in the background art that the current market uses agitators and metal scrapers to process plastic particles attached to the inner wall of the equipment, but during the mixing process, the recycled plastic particles often agglomerate. This agglomeration makes it difficult for the agitators and metal scrapers to mix, thus significantly affecting the uniformity of mixing and further reducing the overall mixing efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a plastic particle mixing machine for cable material processing, comprising a mixing box, two sets of feeding hoppers on the mixing box, the feeding hoppers being connected to the top of the mixing box via feeding pipes, a drive box mounted on the mixing box, a motor inside the drive box, a rotating shaft connected to the output end of the motor, the rotating shaft penetrating inside the mixing box, a stirring structure mounted on the outside of the rotating shaft, the stirring structure including a stirring element and a scraper mounted on the outside of the rotating shaft, and an air supply assembly mounted on the outside of the rotating shaft. Two sets of support boxes are installed on the outside of the rotating shaft. The upper and lower ends of the support boxes are connected to the outside of the rotating shaft through bearings. The rotating shaft has a through hole on the outside of the inner cavity of the support box. The through hole is connected to the inner cavity of the rotating shaft. A shape memory alloy sheet is installed inside the through hole near the sleeve. The top of the shape memory alloy sheet is fixedly connected to the top of the through hole. After the shape memory alloy sheet is deformed, it rotates and unfolds to the outside of the through hole. An air jet box is threadedly connected to the outside of the support box. A threaded groove is opened on the outside of the support box. A threaded ring that matches the threaded groove is installed on the side end of the air jet box. An air delivery hole is opened on the outside of the air jet box.

[0008] Preferably, the gas delivery assembly includes a sleeve installed on the outside of the rotating shaft. The sleeve is connected to the inner wall of the mixing box through a support block. The inner cavity of the sleeve is connected to the inner cavity of the rotating shaft. The upper and lower ends of the sleeve are connected to the outside of the rotating shaft through bearings. A first pipe is provided on the sleeve, and a nozzle is connected to the first pipe. The nozzle is located at the side end of the feed pipe.

[0009] Preferably, the support box and the jet box are fixedly connected by fixing bolts passing through the threaded ring and the threaded groove, and the feed hopper is connected to the mixing box by a support assembly.

[0010] Preferably, the support assembly includes a support frame mounted on the feed hopper, the support frame mounted on the mixing box, a support cylinder mounted on the support frame, and a support rod movably connected to the top of the support cylinder.

[0011] Preferably, a first spring is sleeved on the outside of the support rod and the support cylinder, the inner cavity of the support cylinder is connected through a second pipe, and an auxiliary cylinder is connected to the end of the second pipe. The auxiliary cylinder is installed inside the drive box.

[0012] Preferably, the drive box has an air supply pipe that is connected to an external air pump, and the air supply pipe is connected to a third pipe and a first pipe through a tee connector.

[0013] Preferably, an auxiliary component is installed inside the auxiliary cylinder. The auxiliary component includes a lifting member installed inside the auxiliary cylinder. The lifting member includes a piston plate that fits inside the auxiliary cylinder and a support rod connected to the piston plate. A second spring is sleeved on the outside of the support rod of the lifting member.

[0014] Preferably, the lifting component support rod extends through the auxiliary cylinder into the interior of the third pipe, a block is connected to the top of the lifting component support rod, a sealing seat adapted to the block is installed inside the third pipe, the third pipe extends into the interior of the feed hopper, and the third pipe located inside the feed hopper is set to fit against the inner wall of the feed hopper.

[0015] Preferably, the third pipe has a first downward-sloping jet hole on the outer side of the inside of the feed hopper, and a return pipe is connected to the top of the mixing box. The return pipe extends through the mixing box into the inside of the feed hopper, and a second downward-sloping jet hole is provided on the outer side of the inside of the feed hopper.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: In this plastic particle mixer for cable material processing, the stirring structure rotates within the mixing tank to mix the particles. Through the coordination of gas, the input recycled plastic particles are dispersed, avoiding uneven mixing caused by particle agglomeration and improving overall mixing efficiency. The specific details are as follows: The feed hopper is fixed by an elastic support structure containing a support cylinder, support rod, and a first spring. The impact force when particles are fed in is effectively buffered by the spring, avoiding structural damage to the feed hopper and mixing box caused by the impact force under rigid connection. In addition, the gravity of the particles inside the feed hopper presses down the support rod, causing the support rod to squeeze the support cylinder and transport the gas inside the cylinder, which is convenient for later use.

[0017] The equipment uses a combination of agitators and an air jet system. The agitator blades can be flexibly replaced according to the particle characteristics to enhance adaptability to particles with different characteristics. The nozzles blow away and bounce the feed particles, and the air jet box extends from the rotating shaft to all parts of the mixing box to break up agglomerated particles and ensure consistent mixing.

[0018] The gravity of the particles in the feed hopper causes the support rod to move downward, compressing the gas in the support cylinder and transporting it to the auxiliary cylinder through the pipeline. No additional power is needed to power the feeding auxiliary function, which greatly saves energy. At the same time, the external air pump can adjust the gas flow rate and temperature according to the particle size and mixing temperature to achieve precise control.

[0019] The particle gravity triggers the movement of the lifting component inside the auxiliary cylinder, which automatically opens the third pipe. The airflow propels the particles into the material quickly, avoiding accumulation and blockage at the bottom of the feed hopper and reducing manual unblocking costs. After the particles are emptied, the spring resets and the pipe closes automatically, allowing the pipe to be opened and closed without manual operation.

[0020] The gas ejected from the jet box is returned to the feed hopper via the return pipe. The gas is then blown through the inclined jet holes to remove residual particles from the inner wall of the feed hopper. This not only prevents residual materials from affecting the purity of the next mixing and reduces the risk of cross-contamination, but also enables gas recycling and reduces the energy consumption of the air pump.

[0023] 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.

[0024] Example 1: In this example, the gas inside the rotating shaft 6 enters the two sets of support boxes 11 through the through hole 12, allowing the particles inside the mixing box 1 to mix rapidly, thus improving the overall mixing efficiency. Figures 1-8The technical solution shown includes a mixing tank 1 with two sets of feeding hoppers 2. The feeding hoppers 2 are connected to the top of the mixing tank 1 via feeding pipes 3. A drive box 4 is installed on the mixing tank 1, and a motor 5 is installed inside the drive box 4. The output end of the motor 5 is connected to a rotating shaft 6, which runs through the interior of the mixing tank 1. A stirring structure 7 is installed on the outside of the rotating shaft 6, including a stirring element 701 and a scraper 702 installed on the outside of the rotating shaft 6. An air supply assembly is installed on the outside of the rotating shaft 6. Two sets of support boxes 11 are installed on the outside of the rotating shaft 6, with their upper and lower ends connected to the outside of the rotating shaft 6 via bearings. A through hole 12 is opened on the outside of the inner cavity of the supporting box 11, communicating with the inner cavity of the rotating shaft 6. The shaft 6 is located near the sleeve 10. A shape memory alloy sheet 13 is installed inside the through hole 12. The top of the shape memory alloy sheet 13 is fixedly connected to the top of the through hole 12. After deformation, the shape memory alloy sheet 13 rotates and unfolds outward from the through hole 12. An air jet box 14 is threadedly connected to the outside of the support box 11. A threaded groove is opened on the outside of the support box 11. A threaded ring that matches the threaded groove is installed on the side end of the air jet box 14. An air delivery hole is opened on the outside of the air jet box 14. The air delivery assembly includes a sleeve 10 installed on the outside of the rotating shaft 6. The sleeve 10 is connected to the inner wall of the mixing box 1 through a support block. The inner cavity of the sleeve 10 is connected to the inner cavity of the rotating shaft 6. The upper and lower ends of the sleeve 10 are connected to the outside of the rotating shaft 6 through bearings. A first pipe 8 is provided on the sleeve 10. A nozzle 9 is connected to the first pipe 8. The nozzle 9 is located at the side end of the feed pipe 3 to recycle... Plastic particles are fed into two sets of feeding hoppers 2. The feeding hoppers 2 are fixed to the mixing tank 1 by a support frame 16. The support cylinder 17, support rod 18 and first spring 19 on the support frame 16 form an elastic support structure, which can buffer the impact force when the particles are fed in and extend the service life of the equipment. The valve on the feeding pipe 3 is opened, and the particles inside the feeding hopper 2 finally enter the mixing tank 1 through the feeding pipe 3. After the particles enter the mixing tank 1, the motor 5 inside the drive box 4 is started. The output end of the motor 5 drives the rotating shaft 6 to rotate in the mixing tank 1. The stirring structure 7 on the outside of the rotating shaft 6 operates synchronously. The stirring element 701 stirs and mixes the particles. The stirring element 701 set in this application is a stirring blade installed on the outside of the rotating shaft 6. It can be replaced with a similar one according to the actual use, which can improve the equipment. To adapt to particles with different characteristics and enhance the equipment's versatility, the scraper 702 on the outside of the rotating shaft 6 rotates in contact with the inner wall of the mixing tank 1, preventing particles from adhering to the tank wall, reducing material residue and waste, and ensuring the cleanliness of the inner wall of the mixing tank 1, reducing the difficulty of subsequent cleaning. At this time, the external air pump is started, and gas is input through the air supply pipe 28, and split into the first pipe 8 and the third pipe 26 through the three-way connector. The gas is delivered to the nozzle 9 and the sleeve 10 through the first pipe 8. The nozzle 9 blows the recycled plastic particles that enter the mixing tank 1 through the feed pipe 3. The recycled plastic particles are affected by the gas and bounce after contacting the inner wall of the mixing tank 1, which disperses the input recycled plastic particles and avoids the problem of uneven mixing caused by particle agglomeration. The sleeve 10 is connected to the outside of the rotating shaft 6 through a bearing.Its inner cavity is connected to the inner cavity of the rotating shaft 6, allowing gas to enter the interior of the rotating shaft 6. The gas then flows through the through-hole 12 into the support box 11, and then into the jet box 14, which is threadedly connected to the support box 11. Finally, it is ejected from the air outlet on the outside of the jet box 14, breaking up the particles agglomerated at the bottom of the mixing box 1, further improving the mixing uniformity. During the mixing process, the temperature inside the mixing box 1 rises, triggering the rotation of the shape memory alloy sheet 13 inside the through-hole 12 of the support box 11 near the sleeve 10 on the outside of the rotating shaft 6. This causes the through-hole 12 to open, allowing the gas from the rotating shaft 6 to enter the two sets of support boxes 11 through the through-hole 12, resulting in rapid mixing of the particles inside the mixing box 1. The overall mixing efficiency is improved by automatically enhancing the jetting effect as the temperature rises.

[0025] Example 2: In this example, the user can replace the jet box 14 with different air delivery hole diameters as needed to meet the dispersion requirements of particles of different sizes, improving the flexibility of the equipment. Specifically, as follows... Figure 2 and Figures 9-11 As shown, the following is disclosed: the support box 11 and the jet box 14 are fixedly connected by fixing bolts 15 passing through the threaded ring and the threaded groove. The feed hopper 2 is connected to the mixing box 1 through a support assembly. The support assembly includes a support frame 16 installed on the feed hopper 2. The support frame 16 is installed on the mixing box 1. A support cylinder 17 is installed on the support frame 16. A support rod 18 is movably connected to the top of the support cylinder 17. A first spring 19 is sleeved on the outside of the support rod 18 and the support cylinder 17. The inner cavity of the support cylinder 17 is connected through a second pipe 20. An auxiliary cylinder 21 is connected to the end of the second pipe 20. The auxiliary cylinder 21 is installed inside the drive box 4. Gas enters the two sets of support boxes 11 through the through hole 12 and then flows into the jet box 14 which is threadedly connected to the support box 11. The threaded groove on the outside of the support box 11 is adapted to the threaded ring on the side end of the jet box 14. The device is further secured by fixing bolts 15, allowing users to replace the jet box 14 with different air outlet diameters as needed to meet the dispersion requirements of particles of different sizes, thus improving the flexibility of the equipment. The external air pump can adjust the gas flow rate and temperature according to the particle size and the overall temperature during mixing, achieving precise control, ensuring the mixing effect while avoiding energy waste. It also achieves the dual effect of effective mixing and cooling of particles, preventing particles from sticking together due to high temperature. When there are particles in the feed hopper 2, the gravity of the particles causes the support rod 18 to move down inside the support cylinder 17, which compresses the first spring 19 on the outside of the support cylinder 17 and the support rod 18. The gas inside the support cylinder 17 is transported to the auxiliary cylinder 21 through the second pipe 20, realizing automatic gas transportation by utilizing the gravity of the material without the need for additional power, thus saving energy.

[0026] Example 3: In this example, the airflow is ejected through the downward-sloping second jet hole 30 on the outside of the return pipe 29. The airflow cleans the inner wall of the feed hopper 2 and the residual particles, preventing residual particles from affecting the purity of the next mixing. Specifically, as shown below... Figure 2 and Figures 9-12As shown, the following is disclosed: A gas supply pipe 28, connected to an external air pump, is installed inside the drive box 4. The gas supply pipe 28 is connected to a third pipe 26 and a first pipe 8 via a tee connector. An auxiliary assembly is installed inside the auxiliary cylinder 21. The auxiliary assembly includes a lifting component 22 installed inside the auxiliary cylinder 21. The lifting component 22 includes a piston plate fitted inside the auxiliary cylinder 21 and a support rod connected to the piston plate. The end of the second pipe 20 is located at the upper end of the piston plate inside the auxiliary cylinder 21. A second spring 23 is sleeved on the outside of the support rod of the lifting component 22. The support rod of the lifting component 22 extends through the auxiliary cylinder 21 into the third pipe 26. A plug 24 is connected to the top of the support rod of the lifting component 22. A sealing seat 25 adapted to the plug 24 is installed inside the third pipe 26. The third pipe 26 extends into the inside of the feed hopper 2, and is positioned against the inner wall of the feed hopper 2. A first downward-sloping jet nozzle 27 is located on the outer side of the feed hopper 2. A return pipe 29 is connected to the top of the mixing tank 1, extending through the mixing tank 1 into the feed hopper 2. A second downward-sloping jet nozzle 30 is located on the outer side of the feed hopper 2. The lifting component 22 inside the auxiliary cylinder 21 moves downward under pressure, overcoming the elastic force of the second spring 23. The lifting component 22 causes the top block 24 to disengage from the sealing seat 25 inside the third pipe 26, thus opening the third pipe 26. An external air pump starts, and gas is input through the gas delivery pipe 28 and connected via a three-way valve. The gas is diverted to the first pipe 8 and the third pipe 26. The gas flowing into the third pipe 26 is transported along the pipe to the inside of the feed hopper 2 and ejected through the first downward-sloping jet hole 27 on the outside of the third pipe 26. The airflow pushes the particles in the feed hopper 2 into the feed pipe 3 quickly, effectively improving the feeding efficiency, preventing particles from accumulating and clogging at the bottom of the feed hopper 2, reducing manual unclogging costs, and ensuring a smooth feeding process. The particles finally enter the mixing box 1 through the feed pipe 3. After the particles in the feed hopper 2 have been introduced, the particles lose their gravity, the second spring 23 in the auxiliary cylinder 21 resets, and pushes the lifting component 22 upward, causing the block 24 to re-fit with the sealing seat 25, thus closing the third pipe 26 and realizing the automatic opening and closing of the third pipe 26, improving the automation of the equipment. When the valve on the feed pipe 3 is closed, the mixing box 1 is a sealed space. Therefore, the gas ejected from the air outlet on the outside of the air jet box 14 will be transported to the feed hopper 2 through the return pipe 29 at the top of the mixing box 1. Since the whole is made of processed plastic particles, the transmission channel will not be blocked due to dust and debris in the plastic particles, which improves the overall practicality. The gas is ejected through the second air jet 30 on the outside of the return pipe 29, which is tilted downward. The airflow blows and cleans the inner wall of the feed hopper 2 and the residual particles, so as to avoid the residual particles affecting the purity of the next mixing, realize the recycling of gas, and save energy. The valve on the feed pipe 3 is opened again to facilitate the collection of residual particles to fall into the mixing box 1 for effective mixing.
