Description

Technical Field

[0001] The present invention relates to the technical field of PVC plastic crushing, and particularly to a crusher for PVC plastic production and recycling. Background Art

[0002] PVC plastic, namely polyvinyl chloride, is a common thermoplastic. It is made from vinyl chloride monomers through polymerization reactions. PVC plastic has high mechanical strength, strong corrosion resistance, excellent electrical insulation, and low cost. It has extremely wide applications. In the construction field, 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, artificial leather, etc. In the electrical field, it can be used as the insulating layer of wires and cables; The patent application with the publication number CN205761554U discloses a new type of PVC plastic waste recycling crusher, which includes a motor, a speed regulator, a cutter roller, and a bagging and sealing machine. One side of the motor is connected to the speed regulator, and on the other side of the speed regulator, there is a coupling. The coupling is connected to the main shaft, and the cutter roller is installed on the main shaft. An outer casing is installed outside the main shaft. A waste inlet is provided above the outer casing. One side of the outer casing is connected to an electrical control box. One end of the outer casing is provided with an output connector, and the output connector is connected to an output conduit. One end of the output conduit is connected to the bagging and sealing machine, and a sub-motor is installed on the bagging and sealing machine; After the above patent finishes crushing, it can be directly bagged for processing. However, during the crushing process, because the PVC plastic has moisture, the presence of water will cause the PVC plastic to soften, thereby increasing its flexibility and resulting in low crushing efficiency. Moreover, the presence of moisture causes the PVC plastic powder to adhere together, reducing the crushing efficiency. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the present invention provides a crusher for PVC plastic production and recycling to solve the problems raised in the above background art.

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A crusher for PVC plastic production and recycling includes a placement seat. The outer wall of the placement seat is fixedly connected with a control box. The top of the placement seat is fixedly connected with an inlet bin, and the top of the placement seat is fixedly connected with a processing mechanism; The processing mechanism includes: A motor, which is fixedly connected to the top of the placement seat; A gear set, which is movably connected to the motor; A crushing component, which is rotationally connected to the gear set; Swing assembly, the swing assembly is fixedly connected to the top of the placement seat. The cooperation between the bump structure of the swing assembly and the heater fan causes the feed bin to swing periodically under the drive of the disc, enabling the PVC plastic raw material to shake sufficiently during the feeding process, prompting the surface water stains to fall off. At the same time, the heater fan blows hot air into the feed bin to accelerate the evaporation of moisture. The dual effects significantly reduce the humidity of the raw material, avoiding the problem of increased flexibility of PVC caused by water absorption and softening, 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, and the transmission component is also fixedly connected to the top of the placement seat. First, place the PVC plastic to be crushed into the feed bin. During the rotation of the transmission component, it will drive the disc to rotate. The first bearing is fixedly connected to a position on the disc away from the center of the circle, so it will drive the rotation of the first bearing. The connecting rod is connected through the first bearing and the second bearing respectively, so that the disc will drive the feed bin to bump during rotation. The bumping of the feed bin will drive the PVC plastic on it to shake, and then the water stains on the PVC plastic will fall off. Moreover, when the disc drives the first bearing to rotate to the top position, it will drive one side of the feed bin to lift, and then the feed bin will guide the PVC plastic to move towards the inlet bin. And the third bearing is connected to the other side of the feed bin, so it limits the position of one side of the feed bin. The heater fan is arranged on the feed bin, and then the hot air blows into the feed bin, which will guide the water stains to move in the opposite direction of the inlet bin, thereby accelerating the drying of the PVC plastic.

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

[0007] Preferably, a bracket is fixedly connected between the heater fan and the feed bin.

[0008] Preferably, the bottom of the feed bin is rotatably connected to a second bearing, one end of a connecting rod is rotatably connected to the outer wall of the second bearing, and the other end of the connecting rod is rotatably connected to a first bearing. During the process of crushing PVC plastic, the intercepting valve is in the closed state. Then, when the air flow component is powered on and started, it will blow air into the inlet bin. The air flow will go upward from the bottom position of the crushing component, and then clean the moisture on the PVC plastic, reducing the adhesion of PVC plastic powder together. After crushing for a period of time, the intercepting valve will open for five minutes, and then the air outlet of the air flow 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. The air flow is discharged from the filtering component. Combining with Bernoulli's principle, the passing of the air flow at this time will increase the vertical air flow velocity. Then, the greater the air flow velocity, the smaller the pressure. Furthermore, under the guidance of the pressure, the PVC plastic powder entering the bin will be sent to the storage box. When the air flow passes through the filtering bin 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 placing seat. The air flow component in the auxiliary mechanism blows the air flow upward during the crushing process, forming a wind pressure from bottom to top. On the one hand, it blows away the PVC powder generated during the crushing process to prevent it from agglomerating into blocks due to static electricity or residual moisture. On the other hand, it accelerates the discharge of moisture in the crushing bin through air flow circulation. Combining with the stage-by-stage closing of the intercepting valve to control the air flow direction, it ensures that the crushing environment remains dry, effectively solving the problem of powder agglomeration.

[0011] Preferably, the auxiliary mechanism includes an intercepting valve. The intercepting valve is fixedly connected to the inner top of the placing seat. The intercepting valve is communicated with the bottom of the inlet bin. A storage box is fixedly connected to the bottom of the intercepting valve. A door panel is rotatably connected to the outer wall of the storage box. An air flow component is fixedly connected to the top of the intercepting valve. A filtering component is fixedly connected to the outer wall of the storage box. When the intercepting valve is opened, the air flow component switches to the downward blowing mode. When the high-speed air flow passes through the storage box, a low-pressure area is formed. The pressure difference generated by Bernoulli's principle quickly sucks the PVC powder entering the bin into the storage box, significantly improving the powder collection efficiency. At the same time, the filtering component realizes efficient gas-solid separation through the filter cotton and multiple filtering holes, avoiding the escape of powder and polluting the environment.

[0012] Preferably, the filtering component includes a connecting pipe. The connecting pipe is fixedly connected to the outer wall of the storage box. The storage box and the filtering component adopt a detachable design. The door panel and the connecting pipe are convenient for opening and closing and cleaning, and the filter cotton can be replaced regularly. This structure simplifies the equipment maintenance process while ensuring continuous operation, especially suitable for the crushing scenario of high-humidity raw materials, extending the service life of the equipment and reducing the operation and maintenance cost. A filtering bin is fixedly connected to the outer wall of the connecting pipe. Filtering holes are opened on the outer wall of the filtering bin. Filter cotton is fixedly connected to the inner wall of the filtering bin.

[0013] The present invention provides a crusher for PVC plastic production and recycling. It has the following beneficial effects: 1. The crusher for PVC plastic production and recycling, through the cooperation of the bump structure of the swinging component and the hot air blower, the feeding bin swings periodically under the drive of the disc, making the PVC plastic raw materials shake sufficiently during the feeding process, promoting the shedding of surface water stains. At the same time, the hot air blower blows hot air into the feeding bin to accelerate the evaporation of moisture. The dual effects significantly reduce the humidity of the raw materials, 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. The crusher for PVC plastic production and recycling, through the air flow component in the auxiliary mechanism blowing air upward during the crushing process to form an upward wind pressure. On the one hand, it blows away the PVC powder generated during the crushing process to prevent it from agglomerating into blocks due to static electricity or residual moisture. On the other hand, it accelerates the discharge of moisture in the crushing bin through air flow circulation, and combines with the phased closing of the intercept valve to control the air flow direction, ensuring that the crushing environment remains dry continuously, effectively solving the problem of powder agglomeration.

[0015] 3. The crusher for PVC plastic production and recycling, when the intercept valve is opened, the air flow component switches to the downward blowing mode. The high-speed air flow forms a low-pressure area when passing through the storage box, and uses the pressure difference generated by Bernoulli's principle to quickly suck the PVC powder entering the bin into the storage box, significantly improving the powder collection efficiency. At the same time, the filter component realizes efficient gas-solid separation through the filter cotton and multiple filter holes, avoiding powder escaping and polluting the environment.

[0016] 4. The crusher for PVC plastic production and recycling, the storage box and the filter component adopt a detachable design, and the door panel and the connecting pipe are convenient for opening and closing and cleaning, and the filter cotton can be replaced regularly. This structure simplifies the equipment maintenance process while ensuring continuous operation, is especially suitable for the crushing scenario of high-humidity raw materials, extends the service life of the equipment and reduces the operation and maintenance costs.
