[0036] S1. Prepare materials: preliminarily sort the materials to be shredded to remove any large foreign matter or impurities that may affect the operation of the equipment;

[0037] S2, feeding from the feeding port: open the feeding port on the left side of the pressure chamber 2, and slowly and evenly feed the material into the pressure chamber 2;

[0038] S3, starting the driving motor 301: starting the driving motor 301 drives the first transmission wheel 304 to rotate, and through the transmission of the first transmission belt 308, the second transmission wheel 307 rotates, and then drives the rotating shaft 306 to rotate;

[0039] S4, the pressing auger 312 assists in feeding: as the rotating shaft 306 rotates, the driving shaft 310 is driven to rotate; the driving shaft 310 rotates so that the third transmission wheel 311 fixed thereto rotates, and the fourth transmission wheel 313 is driven to rotate through the second transmission belt 314, so that the pressing auger 312 starts to work; when the pressing auger 312 rotates, its spiral blades rotate continuously, pushing the materials located near it downward along the spiral direction, further assisting the materials to enter the shredder quickly and stably, and avoiding the accumulation or blockage of the materials in the pressing chamber 2;

[0040] S5, the driving roller 302 and the pressing plate 303 work: at the same time, the driving motor 301 drives the driving roller 302 to rotate, and the seven pressing plates 303 evenly distributed on the outer surface of the driving roller 302 rotate accordingly; during the rotation process, the pressing plate 303 continuously presses the material downward, so that it gradually approaches the working area of ​​the shredder.

[0041] Example 1: Processing of Fluffy Materials (Taking Waste Foam as an Example)

[0042] Material pretreatment: The collected waste foam is often mixed with impurities such as paper pieces and dust. First, place the waste foam on a vibrating screen and remove the dust and small pieces of paper through vibration screening. For foam blocks that are too large, use a knife to cut them into appropriate sizes to facilitate subsequent feeding.

[0043] Equipment installation and debugging: Install the shredder hopper 1 and the pressure chamber 2 according to the design requirements, ensure that the connection between the two is tight, and firmly connected through the threaded fixing rod; after the installation is completed, turn on the power of the drive motor 301 and start the equipment without load; observe the rotation of the drive roller 302 and the pressure auger 312, and check whether there is any jamming or abnormal noise; if any problems are found, check the transmission components in time, such as the tension of the first transmission belt 308, the second transmission belt 314, and the meshing of the gear set 309, and make corresponding adjustments.

[0044] Feeding operation: open the feeding port on the left side of the pressing chamber 2, and slowly put the pre-treated waste foam in; use a small amount and multiple times method, after each feeding, wait for the material to start moving downward under the action of the pressing mechanism, and then carry out the next feeding.

[0045] Equipment operation principle and effect: The driving motor 301 drives the first transmission wheel 304 to rotate, and the second transmission wheel 307 is rotated through the first transmission belt 308, thereby driving the rotating shaft 306 to rotate; the rotating shaft 306 drives the driving shaft 310 to rotate through the gear set 309, and the third transmission wheel 311 on the driving shaft 310 rotates accordingly, and then drives the fourth transmission wheel 313 to rotate through the second transmission belt 314, and finally the pressing auger 312 starts to work; when the spiral blades of the pressing auger 312 rotate, they push the nearby waste foam downward in the spiral direction, further assisting the feeding, ensuring that the waste foam enters the shredder quickly and stably, and improving the processing efficiency.

[0046] At the same time, the driving motor 301 is started, and the motor output shaft drives the driving roller 302 to rotate, and the seven pressing plates 303 evenly distributed on the driving roller 302 rotate accordingly; during the rotation process, the pressing plates 303 continuously press downward the waste foam entering the pressing chamber 2; because the waste foam is fluffy and easy to float, the downward pressure of the pressing plates 303 effectively overcomes this problem, allowing it to gradually approach the working area of ​​the shredder to avoid blockage at the feed port.

[0047] Equipment maintenance: In the process of handling waste foam, since foam debris may adhere to the equipment components, the equipment operation needs to be suspended every once in a while, such as 4 hours, to clean the inside of the press chamber 2; use a brush to clean the foam debris on the surface of the press plate 303 and the press auger 312 to prevent their accumulation and affect the normal operation of the equipment; at the same time, check the temperature of the drive motor 301. If the temperature is too high, it can be cooled by the cooling fan to ensure continuous and stable operation of the equipment.

[0048] Example 2: Processing of smooth materials (taking waste glass balls as an example)

[0049] Material preparation: The collected waste glass balls may be mixed with metal particles, stones and other impurities; first use an electromagnet to adsorb the material to remove the metal particles; then, pass the material through a sorting conveyor belt and manually pick out larger impurities such as stones; in order to increase the friction on the surface of the glass ball and facilitate feeding, spray a small amount of water on the surface of the glass ball to make its surface slightly moist.

[0050] Equipment preparation and inspection: Check the opening and closing of the feeding port on the left side of the pressure chamber 2 to ensure that it can be opened and closed smoothly; check whether the connection between the drive motor 301 and each transmission component is firm, especially whether the first transmission belt 308 and the second transmission belt 314 show signs of looseness; if there is any looseness, adjust the position of the transmission wheel in time to ensure the transmission effect.

[0051] Feeding process: open the feeding port and slowly pour the prepared waste glass balls into the pressing chamber 2; since the surface of the glass balls is smooth, pay attention to controlling the speed when pouring to avoid them rolling around in the pressing chamber 2 and affecting the feeding efficiency; auxiliary tools such as funnels can be used to concentrate the glass balls near the pressing auger 312 to facilitate their grabbing and pushing.

[0052] Equipment operation and working principle: Start the drive motor 301, the drive roller 302 and the pressure plate 303 start to work, and the pressure plate 303 generates downward pressure on the glass balls when rotating, prompting the glass balls to move to the working area of ​​the shredder; at the same time, the pressure auger 312 starts to rotate driven by the transmission system; when its spiral blades come into contact with the glass balls, they can provide an additional downward propulsion force; even if the surface of the glass balls is smooth, they can smoothly enter the shredder under the continuous action of the pressure auger 312, solving the problem that smooth materials are not easy to be grasped and fed.

[0053] Equipment maintenance and precautions: After processing waste glass balls, the equipment components may be subject to a certain degree of wear; after each processing is completed, check the spiral blades of the pressing auger 312 and the surface wear of the pressing plate 303; if the blades or the pressing plate 303 are found to be obviously worn, replace the corresponding parts in time to ensure the normal working performance of the equipment; during the operation of the equipment, pay attention to the feeding of the glass balls. If the feeding is not smooth or the glass balls are accumulated in the pressing chamber 2, the speed of the drive motor 301 can be appropriately adjusted to optimize the feeding effect.

[0054] Example 3: Safe operation and maintenance scenario

[0055] Safety considerations for the design of the feeding port: This device sets the feeding port on the left side of the pressure chamber 2 instead of the top. This design greatly improves the operational safety. If the feeding port is on the top, the operator needs to work above the equipment when feeding, which can easily cause injuries due to material sliding, sudden equipment failure, etc. If it is set on the left side, the operator can feed from the side without having to reach into the dangerous area above the equipment. For example, when handling scraps and other materials, even if the material is accidentally ejected, it is not easy to cause serious injury to the operator, reducing the risk of safety accidents.

[0056] Safety protection during equipment operation: Before the equipment is operated, it is necessary to fully check the sealing of the connection between the pressing chamber 2 and the shredder hopper 1 to prevent leakage and splashing of materials during transportation; at the same time, carefully check whether the protective casing of the drive motor 301 is intact to avoid accidental touch and injury when the motor is running; when the equipment is running, it is strictly forbidden to open the feeding port or touch the running parts of the equipment; if you want to clean the equipment, you must first cut off the power supply of the drive motor 301, and wait until the pressing auger 312 and the drive roller 302 stop rotating completely before operating to prevent safety accidents caused by accidental start-up of the equipment.

[0057] Regular safety inspection and maintenance: It is essential to conduct regular safety inspections on the equipment. Check the threaded fixing rods for looseness every other week. If so, tighten them in time to ensure that the pressure chamber 2 is firmly connected to the shredder hopper 1 to prevent displacement or falling off during equipment operation. Check the protective devices of the transmission belt and gear set 309 once a month to see if they are damaged or loose. If there are any problems, repair or replace them in time to avoid exposure of transmission parts and danger to personnel. Check the electrical circuit of the drive motor 301 every quarter to see if it is aging or damaged, and replace the damaged circuit in time to prevent electrical failures from causing fire or electric shock accidents.

[0058] In summary, the pressing device for the shredder and the method of using the same drive the driving motor 301 to drive the driving roller 302 and the seven pressing plates 303 evenly distributed thereon. When the device is started, the driving motor 301 rotates the driving roller 302, and the pressing plates 303 rotate accordingly. During the rotation, the pressing plates 303 continuously push downward the materials entering the pressing chamber 2, so that the materials gradually approach the working area of ​​the shredder. This process effectively solves the problem that fluffy materials are easily blocked at the feed port, because the pressing plates 303 can continuously apply pressure to ensure that the materials enter the shredder evenly and stably, avoiding the occurrence of accumulation and blockage. At the same time, this structural design also reduces the additional wear and increased energy consumption caused by material retention, and improves the overall processing capacity and efficiency of the equipment.

[0059] In addition, the material pressing device for the shredder and the method of using the same are characterized in that the material pressing auger 312 is linked by the gear set 309, the drive shaft 310, the third transmission wheel 311 and the second transmission belt 314. After the drive motor 301 is started, the rotating shaft 306 drives the drive shaft 310 to rotate, thereby starting the material pressing auger 312 to work. During the rotation of the spiral blades of the material pressing auger 312, the material located near it is pushed downward along the spiral direction, further assisting the material to enter the working area of ​​the shredder quickly and stably. In particular, for objects with smooth surfaces and round shapes that are not easy to be grasped, the material pressing auger 312 can provide additional propulsion force to ensure that these materials can smoothly enter the shredder for processing. This not only improves the adaptability of the shredder to materials with special physical properties, but also significantly improves the overall work efficiency and processing effect, and solves certain limitations in the design of traditional shredders, especially when processing materials with special physical properties, such as fluffy or rounded objects; these materials are difficult to quickly enter the working area of ​​the shredder due to their own characteristics, affecting the overall work efficiency and processing effect; for example, fluffy materials may form blockages at the feed port, while rounded materials may be retained in the feed area due to their smooth surface and difficult to be grasped; these problems not only reduce the actual processing capacity of the shredder, but may also cause additional wear and tear on the equipment and increased energy consumption.
