Description

Technical Field

[0001] The present invention relates to the technical field of recycled plastic particles, and specifically relates to a device for preparing recycled plastic particles. Background Art

[0002] Plastic particles are mainly plastic products produced by granulating machines from waste plastic films, industrial packaging films, agricultural mulch films, greenhouse films, etc. The plastic granulating machine can heat and soften the waste film, and then shear it to output plastic particles.

[0003] In the application number: CN202323323103.5, a device for preparing recycled plastic particles is disclosed, including: a granulating machine body; a downwardly inclined inclined conduit is fixedly connected to the discharge end of the granulating machine body, one end of the inclined conduit is fixedly connected to a receiving box, one end of the receiving box is fixedly connected to a first fan, one end of the receiving box is fixedly connected to a cooling output pipe, one end of the cooling output pipe is fixedly connected to a cyclone separator, and the gas outlet end of the cyclone separator is fixedly connected to a second fan. The present invention can quickly cool the high-temperature plastic particles output by the granulating machine body, without spending a long time waiting for cooling and then packing and transferring, improving the processing efficiency.

[0004] However, in order to ensure the cooling effect of the plastic particles, the device is provided with a cooling output pipe. The middle section of the cooling output pipe is the farthest from the two fans, resulting in insufficient wind force. And if there are too many plastic particles, it is more likely to cause blockage of the particles inside the cooling output pipe. At the same time, the device also lacks a preliminary screening function for the particles. Therefore, a device for preparing recycled plastic particles is proposed, which can reduce the occurrence of blockage during the transportation of plastic particles, and can also provide cooling and screening functions for plastic particles. Summary of the Invention

[0005] In view of the problems in the prior art, the present invention provides a device for preparing recycled plastic particles, which can reduce the occurrence of blockage during the transportation of plastic particles, and can also provide cooling and screening functions for plastic particles.

[0006] The technical solution adopted by the present invention to solve its technical problems is a device for preparing recycled plastic particles, including a feeding box and a top cover. A cavity is opened inside the feeding box. A filter screen cylinder is horizontally installed inside the cavity. The filter screen cylinder is sleeved outside the auger rod. One end of the auger rod is fixedly connected to the output end of the motor, and the motor is fixedly installed at one end of the feeding box;

[0007] An inlet is opened on one side of the feeding box for one end of the inclined conduit to be installed and inserted. The end of the inclined conduit away from the feeding box is fixedly connected to the discharge end of the granulating machine body, and the inside of the inclined conduit is communicated with the inside of the filter screen cylinder.

[0008] By adopting the above technical solution, the auger rod drives the plastic particles to be spirally conveyed inside the filter screen cylinder. During the driving process, unqualified particles and impurities are automatically separated and discharged centrally through the chip discharge port, realizing continuous screening operation. At the same time, multiple air supply square pipes evenly introduce the cooling air flow generated by the fan into the inside of the filter screen cylinder, forming a penetrating cooling perpendicular to the material conveying direction, significantly reducing the particle temperature. This design integrates the functions of screening, conveying, and cooling, greatly improving the comprehensive processing capacity of the production line.

[0009] Specifically, a top cover is snap-fitted and installed on the top of the feeding box. A wind collecting hood is fixedly installed on the top of the top cover, and an electric fan is fixedly installed at the top end of the wind collecting hood.

[0010] By adopting the above technical solution, the electric fan constructs a forced ventilation system through the wind collecting hood. When the top cover and the feeding box are assembled, a complete cooling air flow channel is formed.

[0011] Specifically, the output end of the fan is inserted into the inside of the wind collecting hood. The bottom end of the top cover is provided with air supply square pipes, and there are multiple air supply square pipes. The inside of the multiple air supply square pipes is communicated with the inside of the wind collecting hood.

[0012] By adopting the above technical solution, the cooling air flow generated by the electric fan forms distributed air supply through multiple air supply square pipes, ensuring that each section of the filter screen cylinder can obtain uniform cooling air flow.

[0013] Specifically, the top end of the feeding box is provided with air inlets, and there are multiple air inlets for multiple air supply square pipes to be vertically inserted.

[0014] By adopting the above technical solution, the vertically inserted air supply square pipes directly introduce the cooling air flow into the operation area of the filter screen cylinder through the air inlets, realizing penetrating cooling perpendicular to the material conveying direction.

[0015] Specifically, a discharge pipe is provided at one end of the feeding box away from the motor. The inside of the discharge pipe is communicated with the inside of the filter screen cylinder, and a connecting pipe is sleeved at one end of the discharge pipe away from the filter screen cylinder.

[0016] By adopting the above technical solution, the preliminarily screened plastic particles enter the connecting pipe through the discharge pipe under the push of the auger rod and are finally conveyed to the cyclone separator for subsequent processing.

[0017] Specifically, a chip discharge port is opened at the bottom end of the feeding box, and two supporting legs are fixedly connected to the bottom end of the feeding box.

[0018] By adopting the above technical solution, the unqualified fine particles and impurities screened out by the filter screen cylinder are automatically discharged through the chip discharge port under the action of gravity, and the support legs are used to raise the feeding box to facilitate the discharge of impurities.

[0019] Specifically, one side of the feeding box is movably connected with a bin door through a hinge. On the upper parts of the two opposite sides of the feeding box, a plurality of first connecting blocks are fixedly connected. There are multiple such first connecting blocks. On the lower parts of the two opposite sides of the top cover, a plurality of second connecting blocks are fixedly connected. There are multiple such second connecting blocks. The multiple first connecting blocks are adapted to the multiple second connecting blocks.

[0020] By adopting the above technical solution, the internal maintenance of the equipment can be carried out by opening the bin door. The cooperative installation of the first connecting block and the second connecting block ensures the precise positioning of the top cover and the feeding box, and the bolt connection method facilitates the quick disassembly and assembly during equipment maintenance.

[0021] Advantages of the present invention:

[0022] (1) For the regenerated plastic particle preparation device of the present invention, the plastic particles are driven by the auger rod to be spirally conveyed in the filter screen cylinder. During the driving process, unqualified particles and impurities are automatically separated and centrally discharged through the chip discharge port, realizing continuous screening operation. At the same time, multiple air supply square pipes uniformly introduce the cooling air flow generated by the fan into the interior of the filter screen cylinder, forming a penetrating cooling perpendicular to the material conveying direction, significantly reducing the particle temperature. This design integrates the functions of screening, conveying and cooling, greatly improving the comprehensive processing capacity of the production line.

[0023] (2) For the regenerated plastic particle preparation device of the present invention, the top cover and the feeding box achieve quick alignment through the positioning cooperation of the first connecting block and the second connecting block. The bolt connection method enables quick installation and disassembly. The hinged structure of the bin door can be directly opened for internal maintenance. Combined with the design of the air supply square pipe that can be vertically inserted and pulled out, the cleaning of the filter screen cylinder can be completed without disassembling the whole machine.

[0033] During use, the plastic particles produced by the granulation body 9 are continuously input into the filter screen cylinder 14 through the inclined duct 8. The motor 7 drives the screw rod 16 for spiral conveying to realize the screening and conveying of materials in the filter screen cylinder 14.

[0035] During use, the electric fan 3 constructs a forced ventilation system through the air collecting hood 2. When the top cover 1 and the feeding box 5 are assembled, a complete cooling air flow channel is formed.

[0036] The present invention also includes that the output end of the fan 3 is inserted into the inside of the air collecting hood 2. A plurality of air supply square pipes 11 are provided at the bottom end of the top cover 1. The inside of the plurality of air supply square pipes 11 is communicated with the inside of the air collecting hood 2.

[0037] During use, the cooling air flow generated by the electric fan 3 forms distributed air supply through multiple air supply square pipes 11, ensuring that each section of the filter screen cylinder 14 can obtain uniform cooling air flow.

[0038] This new utility model also includes that a plurality of air inlets 10 are provided at the top end of the feeding box 5, and the multiple air inlets 10 are used for vertically inserting multiple air supply square pipes 11.

[0039] During use, the vertically inserted air supply square pipes 11 directly introduce the cooling air flow into the working area of the filter screen cylinder 14 through the air inlets 10, realizing penetrating cooling perpendicular to the material conveying direction.

[0040] This new utility model also includes that a discharge pipe 17 is provided at one end of the feeding box 5 far away from the motor 7. The inside of the discharge pipe 17 is communicated with the inside of the filter screen cylinder 14, and a connecting pipe 18 is sleeved at one end of the discharge pipe 17 far away from the filter screen cylinder 14.

[0041] During use, the preliminarily screened plastic particles are pushed by the auger rod 16 and enter the connecting pipe 18 through the discharge pipe 17, and are finally conveyed to the cyclone separator for subsequent processing.

[0042] This new utility model also includes that a chip discharge port 15 is provided at the bottom end of the feeding box 5. Two supporting legs 6 are fixedly connected to the bottom end of the feeding box 5.

[0043] During use, the unqualified fine particles and impurities screened out by the filter screen cylinder 14 are automatically discharged through the chip discharge port 15 under the action of gravity, and the supporting legs 6 are used to raise the feeding box 5 to facilitate the discharge of impurities.

[0044] This new utility model also includes that a warehouse door 4 is movably connected to one side of the feeding box 5 through a hinge. A plurality of first connection blocks 19 are fixedly connected to the upper parts of the two opposite sides of the feeding box 5.

At the same time, the motor 7 and the fan 3 are started by an external power supply. The motor 7 drives the auger rod 16 to rotate. The rotation of the auger rod 16 can drive the plastic particles to be conveyed towards the discharge pipe 17 and finally discharged into the cyclone separator through the connecting pipe 18 for subsequent treatment. During the conveying process of the auger rod 16, some impurities or plastic particles with too small particle size will pass through the filter screen cylinder 14 and finally be discharged from the chip discharge port 15. The start of the fan 3 can blow cold air from the air collecting hood 2 into the multiple air supply square pipes 11, and the air in the air supply square pipes 11 will pass through the filter screen cylinder 14 and blow towards the plastic particles, thereby providing a cooling effect on the plastic particles.
