Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic granule production technology, and in particular to a recycling and processing device for polyethylene material granules. Background Technology
[0002] Polyethylene (PE) plays an important role in modern industry and daily life due to its excellent chemical stability, electrical insulation, corrosion resistance, and ease of processing. From packaging films for various products to plastic pipes for transporting liquids and gases, and various injection-molded products such as plastic toys and household goods, PE is ubiquitous. With the development of the global economy and the improvement of people's living standards, the use of PE has shown a continuous growth trend, which has also led to a huge amount of waste generated. If this PE waste is not effectively recycled, it will cause a huge waste of resources. The production of polyethylene raw materials requires the consumption of large amounts of non-renewable resources such as oil and natural gas. If the recyclable resources contained in waste polyethylene materials are left idle, it is undoubtedly an inefficient use of resources. On the other hand, polyethylene materials are difficult to degrade in the natural environment. The accumulation of large amounts of polyethylene waste will cause serious pollution to the ecological environment such as soil, water and air. Waste polyethylene plastic products will hinder the transport of water and nutrients in the soil, affecting plant growth. If they flow into water bodies, they will threaten the survival of aquatic organisms. If animals accidentally ingest them, they may become sick or even die. Incineration will produce harmful gases such as dioxins, which will pollute the atmospheric environment.
[0003] Existing technologies have the following problems:
[0004] Extensive research revealed that some devices exhibit uneven pulverization results when crushing polyethylene particles. Due to unreasonable structural design or movement of the pulverizing components, the polyethylene particles at the bottom of the pulverizing chamber are difficult to fully pulverize, resulting in inconsistent particle sizes in the final recycled particles. This ultimately affects the quality of subsequent products and reduces their market competitiveness. Furthermore, the maintenance costs of existing devices are high. When vulnerable parts such as the pulverizing blades are damaged, the entire pulverizing assembly often needs to be replaced, which is cumbersome and costly. This is detrimental to the long-term operation and sustainable development of enterprises and fails to meet the growing market demand.
[0005] To address these shortcomings, we propose a recycling and processing device for polyethylene material particles. Utility Model Content
[0006] The purpose of this invention is to provide a device for recycling and processing polyethylene material particles in order to overcome the shortcomings of existing technologies.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: a polyethylene material particle recycling and processing device, comprising a crushing box, a feed inlet at the top of the crushing box, and a sealing cap threadedly connected to the top of the feed inlet; a drive motor mounted on the crushing box, and the output shaft of the drive motor connected to a first crushing rod via a synchronous pulley set; spiral conveying blades mounted at both ends of the first crushing rod; a threaded groove provided on the surface of the first crushing rod, and a threaded rod threadedly connected within the threaded groove, with a crushing blade mounted at one end of the threaded rod; a crushing motor mounted on the bottom surface of the crushing box, and a second crushing rod installed inside the crushing box via the output shaft of the crushing motor; a discharge pipe provided at the bottom of the crushing box; and a maintenance plate detachably mounted on the outer side wall of the crushing box via fastening bolts, with a control switch provided on the surface of the maintenance plate.
[0008] Preferably, both the drive motor and the crushing motor are reversible motors.
[0009] Preferably, a valve is installed on the discharge pipe.
[0010] Preferably, a sealing gasket is provided between the inspection plate and the crushing box.

[0012] Preferably, there are multiple fastening bolts, and the multiple fastening bolts are distributed in a ring array on the surface of the inspection plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. In this utility model, by setting the rotation of the first and second crushing rods, together with the crushing blades, polyethylene material particles are uniformly crushed, avoiding the problem that polyethylene material particles at the bottom of the crushing box are difficult to crush evenly. At the same time, the spiral conveying blades can transport polyethylene material particles from both sides inside the crushing box to the middle, resulting in uniform particle size, which is beneficial to improving the quality of subsequent products.
[0015] 2. In this utility model, by opening the inspection plate and rotating the crushing blade, the crushing blade can be removed from the first crushing rod. At the same time, a single severely damaged crushing blade can be replaced individually, which greatly reduces maintenance and replacement costs. Attached Figure Description

A discharge pipe 14 is provided at the bottom of the crushing box 1. A maintenance plate 15 is detachably installed on the outer side wall of the crushing box 1 through fastening bolts 16, and a control switch 5 is provided on the surface of the maintenance plate 15.
[0026] In use, the polyethylene material granules to be recycled are first fed into the crushing box 1 through the feed inlet 2. Then, the operator starts the drive motor 4 and the crushing motor 12 through the control switch 5. The drive motor 4 drives the first crushing rod 7 to rotate, and the crushing motor 12 drives the second crushing rod 13 to rotate. The crushing blades 10 on the first crushing rod 7 and the second crushing rod 13 crush the polyethylene material granules during rotation. At the same time, the spiral conveyor blades 8 convey the polyethylene material granules on both sides of the crushing box 1 to the middle, so that the material granules can be crushed more evenly. After crushing, the valve on the discharge pipe 14 is opened, and the crushed polyethylene material granules are discharged from the device through the discharge pipe 14. When it is necessary to replace the crushing blades 10 or to repair the internal components, the drive motor 4 and the crushing motor 12 are turned off, the fastening bolts 16 are unscrewed, and the inspection plate 15 is opened to perform the corresponding operations.
[0027] In this implementation plan: both the drive motor 4 and the crushing motor 12 are forward and reverse rotating motors.
[0028] Specifically, the rotation direction of the first crushing rod 7 and the second crushing rod 13 can be adjusted according to actual needs.

[0030] Specifically, the discharge rate of the crushed polyethylene material particles can be controlled.
[0031] In this implementation plan, a sealing gasket is provided between the inspection plate 15 and the crushing box 1.
[0032] Specifically, to prevent dust leakage during processing.
[0033] In this implementation scheme: the control switch 5 is connected to the drive motor 4 and the crushing motor 12 by wires, and the control switch 5 has an overload protection function.
[0034] Specifically, to prevent motor damage due to overload, overload protection can be achieved using methods including, but not limited to, fuses.
[0035] In this embodiment, multiple fastening bolts 16 are provided, and the multiple fastening bolts 16 are distributed in a ring array on the surface of the inspection plate 15.
[0036] Specifically, this makes the connection between the inspection plate 15 and the crushing box 1 more stable, less prone to loosening, and also prevents polyethylene material particles from spilling out.
[0037] In this implementation scheme: the control switch 5 is an existing structure, and the control circuit can be implemented by a person skilled in the art through simple programming. It is common knowledge in the art, and it is only used without modification. Therefore, the control method and circuit connection will not be described in detail.
[0038] Working principle: In use, the polyethylene material granules to be recycled are first put into the crushing box 1 through the feed inlet 2. Then, the operator starts the drive motor 4 and the crushing motor 12 through the control switch 5. The drive motor 4 drives the first crushing rod 7 to rotate, and the crushing motor 12 drives the second crushing rod 13 to rotate. The crushing blades 10 on the first crushing rod 7 and the second crushing rod 13 crush the polyethylene material granules during rotation. At the same time, the spiral conveyor blades 8 convey the polyethylene material granules on both sides of the crushing box 1 to the middle, so that the material granules can be crushed more evenly. After crushing, the valve on the discharge pipe 14 is opened, and the crushed polyethylene material granules are discharged from the device through the discharge pipe 14. When it is necessary to replace the crushing blades 10 or to repair the internal parts, the drive motor 4 and the crushing motor 12 are turned off, the fastening bolts 16 are unscrewed, and the inspection plate 15 is opened to perform the corresponding operations.
