[0002] With the vigorous development of social economy, the demand for plastic products in various industries has shown explosive growth. From packaging materials and household items in daily life to mechanical parts and electronic equipment casings in industrial production, plastic products are everywhere. Their wide range of applications and high frequency of use make them an indispensable basic material in modern society. In such an environment, plastic particles, as the key raw material for the production of plastic products, are becoming more and more important in the production and processing links. Modern science and technology are also continuously advancing, constantly promoting the innovation of plastic particle granulation technology.

[0003] However, traditional plastic granulation devices mostly rely on continuous manual feeding. Workers need to expend a lot of physical strength to carry materials into the equipment, which is extremely labor-intensive, especially when handling heavier or larger materials. The workload is heavy. In addition, traditional plastic granulation devices may not fully consider the treatment of gases generated during the granulation process. For gases containing harmful substances such as dust and volatile organic compounds, if they are directly discharged, they will seriously pollute the air quality of the production workshop, endanger the health of operators, and may also violate environmental protection regulations. Summary of the invention

In order to effectively solve this problem, a filter assembly consisting of three filter plates is provided in the device. The generated gas can pass through the three filter plates in turn. The filter net in the filter plate can efficiently intercept impurities and harmful substances in the gas to ensure that the discharged gas meets the environmental protection requirements and the air quality standards of the workshop. However, with the increase of usage time, the filter plate will inevitably be blocked. Once the three filter plates are blocked, the filter plate will inevitably be blocked.

At the same time, it ensures the stable operation of the device, reduces potential damage to the equipment due to untimely gas filtration, and extends the service life of the equipment.

[0017] The outer wall of the driving gear 104 on one side is meshed with the outer wall of the first driven gear 105, and the outer wall of the driving gear 104 on the other side and the outer wall of the second driven gear 108 are both sleeved with a synchronous belt 107. The front end of the upper part of one side of the outer wall of the main body box 101 is fixedly connected with the first motor 102, and the output end of the first motor 102 is fixedly connected to the outer wall of the driving gear 104 on one side. After the first motor 102 is started, it can efficiently and stably transmit power to the driving gear 104, and the gear meshing and the synchronous belt 107 are used to ensure that the crushing rollers 103 and the rotating rod 109 on both sides can operate in coordination, wherein the meshing of the driving gear 104 and the first driven gear 105 drives the crushing roller 103 to initially crush the material, and the driving gear 104 on the other side drives the second driven gear 108 through the synchronous belt 107, so that the rotating rod 109 and the crushing leaves 110 further crush the crushed material.

[0018] The upper end of the main box 101 is fixedly connected to the lower end of the connecting box 301, the front end of the connecting box 301 is fixedly connected to the rear end of the feeding box 201, and the lower end of the main box 101 is fixedly connected to the upper end of the collecting box 8, thereby realizing the close integration of the functional modules of feeding, filtering, crushing and collecting, forming a compact and efficient production system, and the materials can flow smoothly between the components, reducing the scattering and loss of materials during the transportation process, and improving the continuity and stability of production. A drawer 4 is slidingly provided on one side of the inner wall of the collecting box 8, and a guide plate 9 is fixedly connected to one side of the lower end of the inner wall of the main box 101. The guide plate 9 can guide the crushed materials to fall accurately into the drawer 4 in the collecting box 8 to avoid the materials from being scattered everywhere, and the drawer 4 adopts a sliding setting, which is convenient for the staff to take out the collected plastic particles at any time.

[0019] A connection net 302 is provided at the upper end of the inner wall of the connection box 301, and three buttons 7 are provided on the other side of the outer wall of the connection frame 6. The connection net 302 can perform preliminary filtering on the gas entering the connection box 301, intercept larger particles of impurities, reduce the filtering burden of the subsequent filter plate 303, extend the service life of the filter plate 303, and improve the working efficiency of the entire filtering system. The button 7 on the connection frame 6 cooperates with the movement of the filter plate 303. When the filter plate 303 moves due to blockage and triggers the button 7, the corresponding LED flashing light 5 flashes, which can inform the staff which specific filter plate 303 has a problem, so as to facilitate timely maintenance.

[0020] A second motor 204 is fixedly connected to the lower end of the outer wall on the other side of the loading box 201. The output end of the second motor 204 passes through the loading box 201 to the interior of the loading box 201 and is fixedly connected to the outer wall of the lower end connected gear 206. The lower part of the front end of the outer wall of the loading box 201 is connected with the feed plate 202. The second motor 204 provides power for the loading process. After starting, it drives the connecting gear 206 to rotate, so that the toothed belt 203 and the clamping plate 205 operate to realize automatic and stable loading. The staff only needs to place the material on the feed plate 202 to complete the loading operation, which greatly reduces the labor intensity of manual loading.

[0021] Working principle: The staff puts the material to be processed on the feed plate 202, and starts the second motor 204 through the external controller. The second motor 204 drives the lower connecting gear 206 to rotate. Because the toothed belt 203 is sleeved on the two connecting gears 206, the rotation of the lower connecting gear 206 drives the toothed belt 203 to move, and then drives the upper connecting gear 206 to rotate synchronously. The multiple card plates 205 fixed on the outer wall of the toothed belt 203 move with the movement of the toothed belt 203, thereby automatically pushing the material, and sending the material from the feed plate 202 to the connecting box 301 through the feeding box 201, and then into the main box 101. This automatic feeding method avoids the inconvenience of continuous manual feeding, reduces the labor intensity of workers, and ensures the stability and continuity of feeding; After the material enters the main box 101, the first motor 102 is started through the external controller, and the output end of the first motor 102 drives the driving gear 104 on one side to rotate. Since the driving gear 104 is meshed with the first driven gear 105, the first driven gear 105 rotates accordingly, thereby driving the crushing roller 103 connected thereto to crush the material. At the same time, the driving gear 104 on the other side will also rotate, because its outer wall is sleeved with a synchronous belt 107, and the synchronous belt 107 is connected to the second driven gear 108, so the second driven gear 108 will also rotate, thereby driving the rotating rod 109 to rotate, and the multiple crushing leaves 110 fixed on the rotating rod 109 further crush the crushed material. Through this double crushing structure, the material can be fully crushed to obtain plastic particles with more uniform particle size and more in line with production requirements; In the process of squeezing and crushing the material, the crushing roller 103 and the crushing blade 110 contact the material to generate gas containing harmful substances such as dust and volatile organic compounds. These gases are firstly filtered through the connection net 302 set at the upper end of the connection box 301, and then finely filtered through three filter plates 303 with filter nets 304 in sequence to ensure that the exhausted gas meets environmental protection requirements and workshop air quality standards, and protect the health of operators; As the filtering work continues, if any one of the three filter plates 303 is clogged, the air pressure will gradually increase due to poor gas circulation. Since the mounting plate 305 at the lower end of the filter plate 303 is specially designed, the rising gas will push the mounting plate 305 to move outward. When the filter plate 303 moves outward with the mounting plate 305, it will contact the button 7 on the connecting frame 6, thereby triggering the corresponding LED flashing light 5 to start flashing, promptly reminding the staff which filter plate 303 has a clogged problem, so that the staff can quickly locate the fault location and replace or clean the clogged filter plate 303 to ensure the continuity and effectiveness of the filtering work. The fully crushed materials finally fall onto the guide plate 9 fixed on one side of the lower end of the inner wall of the main box 101. With the help of the special shape of the guide plate 9, the materials will slide along the guide plate 9 into the drawer 4 inside the collection box 8, which is convenient for the staff to collect and process them in a centralized manner, thus completing the entire plastic granulation process.
