Description

Technical Field

[0001] This invention relates to the field of PVC plastic crushing technology, specifically a crusher for PVC plastic production and recycling. Background Technology

[0002] PVC plastic, or polyvinyl chloride, is a common thermoplastic plastic made from vinyl chloride monomer through a polymerization reaction. PVC plastic has the characteristics of high mechanical strength, strong corrosion resistance, and excellent electrical insulation, and it is also relatively inexpensive. Its uses are extremely wide. In the construction industry, it can be used to manufacture door and window profiles, pipes, etc. In daily life, it is commonly found in products such as raincoats, plastic films, and artificial leather. In the electrical field, it can be used as an insulation layer for wires and cables. Patent application CN205761554U discloses a novel PVC plastic waste recycling crusher, including a motor, a speed regulator, a cutter roller, and a bagging and sealing machine. The speed regulator is connected to one side of the motor, and a coupling is provided on the other side of the speed regulator. The coupling is connected to the main shaft, and the cutter roller is installed on the main shaft. A housing is installed on the outside of the main shaft, and a waste inlet is provided on the top of the housing. An electrical control box is connected to one side of the housing, and an output connector is provided at one end of the housing. The output connector is connected to an output conduit, and one end of the output conduit is connected to the bagging and sealing machine. An auxiliary motor is installed on the bagging and sealing machine. After the above-mentioned patent is crushed, it can be directly bagged. However, during the crushing process, because the PVC plastic contains moisture, the presence of water will cause the PVC plastic to soften, thereby increasing its flexibility and reducing the crushing efficiency. Moreover, the presence of moisture will cause the PVC plastic powder to stick together, further reducing the crushing efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a shredder for PVC plastic production and recycling, thereby solving the problems mentioned in the background section.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a shredder for PVC plastic production and recycling, comprising a placement seat, a control box fixedly connected to the outer wall of the placement seat, an inlet chamber fixedly connected to the top of the placement seat, and a processing mechanism fixedly connected to the top of the placement seat; The processing mechanism includes: The motor is fixedly connected to the top of the placement base; Gear set, wherein the gear set is movably connected to the motor; A crushing component, which is rotatably connected to a gear set; The oscillating assembly is fixedly connected to the top of the placement base. The oscillating structure of the oscillating assembly works in conjunction with the warm air blower. The feeding hopper oscillates periodically under the drive of the disc, which makes the PVC plastic raw material shake fully during the feeding process, causing surface water stains to fall off. At the same time, the warm air blows hot air into the feeding hopper to accelerate the evaporation of moisture. The dual effect significantly reduces the humidity of the raw material and avoids the problem of increased flexibility caused by PVC softening due to water absorption, thereby improving the cutting efficiency of the subsequent crushing components.

[0005] Preferably, a transmission shaft and a transmission component are rotatably connected between the motor and the gear set. The transmission component is also fixedly connected to the top of the placement seat. First, the PVC plastic to be crushed is placed into the feeding hopper. During the rotation of the transmission component, the disc will rotate. The first bearing is fixedly connected to the disc at a position away from the center, so the first bearing will rotate. The connecting rod is connected through the first bearing and the second bearing respectively, so that the disc will cause the feeding hopper to bounce during the rotation. The bouncing of the feeding hopper will cause the PVC plastic on it to shake, thus causing the water stains on the PVC plastic to fall off. Moreover, when the disc drives the first bearing to rotate to the top position, it will cause one side of the feeding hopper to lift up. Then the feeding hopper will guide the PVC plastic to move into the hopper. The third bearing is connected to the other side of the feeding hopper, so the position of one side of the feeding hopper is limited. The warm air blower is set on the feeding hopper, and the warm air blows out into the feeding hopper, which will guide the water stains to move in the opposite direction of entering the hopper, thus accelerating the drying of the PVC plastic.

[0006] Preferably, the swing assembly includes a third bearing, the bottom of which is fixedly connected to the top of the placement seat, and the top of the third bearing is rotatably connected to a feed hopper, the outer wall of which is fixedly connected to a heater.

[0007] Preferably, a bracket is fixedly connected between the warm air blower and the feeding hopper.

[0008] Preferably, a second bearing is rotatably connected to the bottom of the feeding hopper, and one end of a connecting rod is rotatably connected to the outer wall of the second bearing. The other end of the connecting rod is rotatably connected to a first bearing. During the crushing of PVC plastic, the intercepting valve is closed. Then, the airflow component is powered on and blows airflow into the feeding hopper. The airflow will rise from the bottom of the crushing component and clean the moisture on the PVC plastic, reducing the adhesion of PVC plastic powder. After crushing for a period of time, the intercepting valve will open for five minutes, and then the airflow outlet of the airflow component will face downward.

[0009] Preferably, a disc is rotatably connected to the outer wall of the transmission component, and the first bearing is fixedly connected at a position away from the center of the disc. Airflow is discharged from the filter assembly. According to Bernoulli's principle, the airflow will increase the vertical airflow velocity. Then, the greater the airflow velocity, the lower the pressure. Under the guidance of pressure, the PVC plastic powder entering the chamber is directed to the storage box. When the airflow passes through the filter chamber and the connecting pipe, the PVC plastic powder is filtered by the filter cotton.

[0010] Preferably, an auxiliary mechanism is fixedly connected to the inner top of the placement seat. The airflow component in the auxiliary mechanism blows air upward during the crushing process, forming an upward air pressure. On the one hand, it blows away the PVC powder generated during the crushing process to prevent it from sticking together due to static electricity or residual moisture. On the other hand, it accelerates the discharge of moisture in the crushing chamber through airflow circulation. Combined with the phased closing of the interception valve to control the airflow direction, it ensures that the crushing environment is continuously dry and effectively solves the problem of powder agglomeration.

[0011] Preferably, the auxiliary mechanism includes an interception valve, which is fixedly connected to the inner top of the placement seat and communicates with the bottom of the inlet chamber. A storage box is fixedly connected to the bottom of the interception valve, and a door panel is rotatably connected to the outer wall of the storage box. An airflow component is fixedly connected to the top of the interception valve, and a filter assembly is fixedly connected to the outer wall of the storage box. When the interception valve is opened, the airflow component switches to a downward blowing mode. When the high-speed airflow passes through the storage box, a low-pressure area is formed. The pressure difference generated by Bernoulli's principle quickly draws the PVC powder entering the chamber into the storage box, significantly improving the powder collection efficiency. At the same time, the filter assembly achieves efficient gas-solid separation through filter cotton and multiple filter holes, preventing powder from escaping and polluting the environment.

[0012] Preferably, the filter assembly includes a connecting pipe fixedly connected to the outer wall of the storage box. The storage box and the filter assembly are detachable, facilitating easy opening and closing of the door and the connecting pipe for cleaning, and allowing for periodic replacement of the filter cotton. This structure simplifies equipment maintenance while ensuring continuous operation, making it particularly suitable for crushing high-humidity raw materials, extending equipment lifespan, and reducing maintenance costs. A filter chamber is fixedly connected to the outer wall of the connecting pipe, with filter holes on the outer wall of the filter chamber and filter cotton fixedly connected to the inner wall of the filter chamber.

[0013] This invention provides a shredder for PVC plastic production and recycling. It has the following beneficial effects: 1. This PVC plastic production and recycling crusher, through the synergistic effect of the oscillating component's bumping structure and the warm air blower, causes the feed hopper to oscillate periodically under the drive of the disc, which fully shakes the PVC plastic raw material during the feeding process, promoting the removal of surface water stains. At the same time, the warm air blows hot air into the feed hopper to accelerate the evaporation of moisture. The dual effect significantly reduces the humidity of the raw material, avoiding the problem of increased flexibility caused by PVC softening due to water absorption, thereby improving the cutting efficiency of the subsequent crushing components.

[0014] 2. This PVC plastic production and recycling shredder uses an airflow component in the auxiliary mechanism to blow air upwards during the shredding process, forming an upward air pressure. On the one hand, it blows away the PVC powder generated during the shredding process, preventing it from sticking together due to static electricity or residual moisture. On the other hand, the airflow circulation accelerates the discharge of moisture in the shredding chamber. Combined with the phased closing of the interception valve to control the airflow direction, it ensures that the shredding environment remains dry and effectively solves the problem of powder agglomeration.

[0015] 3. This PVC plastic production and recycling shredder switches the airflow component to a downward blowing mode when the interception valve is opened. The high-speed airflow forms a low-pressure area when passing through the storage box. The pressure difference generated by Bernoulli's principle quickly draws the PVC powder entering the chamber into the storage box, significantly improving the powder collection efficiency. At the same time, the filter component achieves efficient gas-solid separation through filter cotton and multiple filter holes, avoiding powder leakage and environmental pollution.

[0016] 4. This PVC plastic production and recycling crusher features a detachable storage box and filter assembly design. The door panel and connecting pipes are easy to open and close for cleaning, and the filter cotton can be replaced periodically. This structure simplifies equipment maintenance while ensuring continuous operation, and is especially suitable for crushing raw materials with high moisture content, extending equipment life and reducing operating costs.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0021] Example 1, please refer to Figure 1-5 The present invention provides a technical solution: a shredder for PVC plastic production and recycling, including a placement seat 1, a control box 2 fixedly connected to the outer wall of the placement seat 1, an inlet hopper 3 fixedly connected to the top of the placement seat 1, and a processing mechanism 4 fixedly connected to the top of the placement seat 1. Placement seat 1 is placed in the desired position, and entry compartment 3 is set on top of placement seat 1; Processing unit 4 includes: Motor 41 is fixedly connected to the top of the placement base 1; Gear set 44 is movably connected to motor 41; Crushing component 45 is rotatably connected to gear set 44; The swing assembly 46 is fixedly connected to the top of the placement seat 1.

[0022] A drive shaft 43 and a transmission component 42 are rotatably connected between the motor 41 and the gear set 44. The transmission component 42 is also fixedly connected to the top of the placement base 1. When the motor 41 is powered on, it drives the internal start of the transmission component 42. The transmission component 42 drives the transmission shaft 43 to rotate, which in turn causes the gear set 44 to rotate. When the gear set 44 rotates, it drives the two sets of crushing components 45 to rotate alternately. The crushing components 45 are located in the inlet chamber 3 and can crush PVC plastic during rotation.

[0023] The swing assembly 46 includes a third bearing 468, the bottom of which is fixedly connected to the top of the placement seat 1, and the top of the third bearing 468 is rotatably connected to a feed hopper 465. A heater 466 is fixedly connected to the outer wall of the feed hopper 465.

[0024] A bracket 467 is fixedly connected between the heater 466 and the feed hopper 465.

[0025] The bottom of the feed hopper 465 is rotatably connected to a second bearing 464, and the outer wall of the second bearing 464 is rotatably connected to one end of a connecting rod 463, and the other end of the connecting rod 463 is rotatably connected to a first bearing 462.

[0026] The outer wall of the transmission component 42 is rotatably connected to a disk 461, and the first bearing 462 is fixedly connected at a position away from the center of the disk 461.

[0027] First, the PVC plastic to be crushed is placed into the feed hopper 465. During the rotation of the transmission component 42, the disc 461 rotates. The first bearing 462 is fixedly connected to the disc 461 at a position away from the center, thus causing the first bearing 462 to rotate. The connecting rod 463 is connected via the first bearing 462 and the second bearing 464, causing the disc 461 to vibrate during rotation. This vibration of the feed hopper 465 causes the PVC plastic on it to shake, thus causing the PVC plastic to... When water stains fall off, and the disc 461 drives the first bearing 462 to rotate to the top position, it in turn drives one side of the feed hopper 465 to lift up. Then the feed hopper 465 will guide the PVC plastic to move towards the inlet hopper 3. The third bearing 468 is connected to the other side of the feed hopper 465, so the position of one side of the feed hopper 465 is limited. The warm air blower 466 is set on the feed hopper 465, and then the warm air blows out towards the feed hopper 465, which will guide the water stains to move in the opposite direction towards the inlet hopper 3, thereby accelerating the drying of the PVC plastic.

[0028] Example 2, please refer to Figure 1-8 Based on Embodiment 1, the present invention provides a technical solution: An auxiliary mechanism 5 is fixedly connected to the inner top of the placement seat 1.

[0029] The auxiliary mechanism 5 includes an intercept valve 54, which is fixedly connected to the inner top of the placement seat 1. The intercept valve 54 is connected to the bottom of the inlet chamber 3. A storage box 52 is fixedly connected to the bottom of the intercept valve 54. A door panel 53 is rotatably connected to the outer wall of the storage box 52. An airflow component 51 is fixedly connected to the top of the intercept valve 54. A filter assembly 55 is fixedly connected to the outer wall of the storage box 52.

[0030] The filter assembly 55 includes a connecting pipe 552, which is fixedly connected to the outer wall of the storage box 52. The storage box 52 and the filter assembly 55 are designed to be detachable. The door panel 53 and the connecting pipe 552 are easy to open and close for cleaning. The filter cotton 553 can be replaced periodically. This structure simplifies the equipment maintenance process while ensuring continuous operation. It is especially suitable for crushing high-humidity raw materials, extending the service life of the equipment and reducing maintenance costs. The outer wall of the connecting pipe 552 is fixedly connected to the filter chamber 551. The outer wall of the filter chamber 551 has filter holes 554. The inner wall of the filter chamber 551 is fixedly connected to the filter cotton 553. The storage box 52 and the filter assembly 55 are designed to be detachable. During the PVC plastic crushing process, the interceptor valve 54 is closed. Then, the airflow component 51 is energized and blows air into the inlet chamber 3. The airflow rises from the bottom of the crushing component 45, cleaning the moisture from the PVC plastic and reducing the adhesion of PVC plastic powder. After crushing for a period of time, the interceptor valve 54 opens for five minutes, and then the airflow outlet of the airflow component 51 faces downwards, combined with the attached... Figure 1 As shown, the airflow blows downwards into the storage box 52, and then the airflow is discharged from the filter assembly 55. According to Bernoulli's principle, the airflow will increase the vertical airflow velocity at this time. Then, the greater the airflow velocity, the lower the pressure. Under the guidance of pressure, the PVC plastic powder entering the chamber 3 is brought into the storage box 52. When the airflow passes through the filter chamber 551 and the connecting pipe 552, the PVC plastic powder is filtered by the filter cotton 553.
