Description
Technical Field
[0001] This utility model relates to the field of PET composite material processing technology, specifically a PET composite material processing and crushing equipment. Background Technology
[0002] PET composite material, commonly known as polyester resin, needs to be crushed during the recycling and processing of PET materials. By crushing, waste PET products can be broken into particle sizes that meet the requirements of subsequent processes, making it easier for them to be recycled and reused.
[0003] A Chinese patent with publication number CN214187983U discloses a crushing device for processing high-strength PET composite materials, including a main body. Symmetrically arranged supports are mounted on the bottom of the main body. A storage bin is positioned between the supports at the bottom of the main body. A fixing cylinder is fixed to the surface of the supports. A sliding groove is formed through the interior of the fixing cylinder. A connecting block is connected to the sliding groove via a spring. A limit rod is provided at one end of the connecting block. Through the designed fixing cylinder and limit rod, the storage bin can be effectively limited, enhancing the connection between the storage bin and the main body, ensuring the stability of the storage bin, preventing positional displacement, and allowing the storage bin to smoothly and stably receive the crushed material, avoiding material leakage and providing great convenience to the user.
[0004] The aforementioned pulverizing equipment for PET composite material processing only employs a single shearing method, resulting in concentrated material deformation resistance during the cutting process. This requires greater power to complete the pulverization, leading to high cutting resistance and high energy consumption. Therefore, a new pulverizing equipment for PET composite material processing is proposed to address these issues. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background, this utility model proposes a PET composite material processing and crushing equipment.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The PET composite material processing and crushing equipment of this utility model includes a crushing box. Four support legs are fixedly connected to the bottom of the crushing box. Fixed frames are fixedly connected to both sides of the crushing box. An electric motor is installed on one of the fixed frames. The output end of the electric motor is connected to a rotating column. The other end of the rotating column is rotatably installed on another fixed frame. Two connecting frames are fixedly connected to the rotating column. Multiple slitting blades are installed on one connecting frame, and a cutting blade is installed on the other connecting frame. A feed inlet is opened at the top of the crushing box, and a discharge pipe is connected to the bottom of the crushing box. During the crushing process of PET composite material, the electric motor drives the rotating column to rotate, causing the slitting blade and the cutting blade to rotate. The slitting blade can longitudinally cut the material into several segments, and the cutting blade can transversely cut the slitting material. Through the cyclic operation of the two shearing methods, the crushing of the material is realized, which can effectively reduce the resistance in the cutting process, ensure the crushing effect, and reduce the crushing energy consumption.
[0007] Preferably, a feeding hopper is fixedly connected to one side of the inlet. Swing rods are hinged to both sides of the feeding hopper via rotating rods. Two fixed lugs are fixed to the bottom of the swing rods, and a feeding roller is installed between the two lugs via a rotating shaft. A motor is installed on one of the lugs, and the output end of the motor is connected to one end of the rotating shaft. Support frames are fixedly connected to the top of both sides of the feeding hopper, and three springs are fixedly connected between the support frames and the swing rods. During feeding, the material to be crushed is placed into the feeding hopper. The motor operates, causing the feeding rollers to rotate, thus gradually feeding the material into the crushing chamber. This achieves automated feeding. By adjusting the motor speed to match the speed of raw material delivery, material accumulation or blockage is avoided, ensuring uniform and continuous feeding and providing a stable foundation for the subsequent crushing process. When the material thickness is uneven or the amount of material in the hopper changes, the spring force will drive the swing arm to swing up and down around the rotating rod, automatically adjusting the pressure between the feeding roller and the material surface, ensuring that the feeding roller is always in close contact with the material surface, and improving feeding efficiency.
[0008] Preferably, a fixing block is fixed to both sides of the feed port, and a hollow tube is installed on the two fixing blocks. Multiple nozzles are connected to the hollow tube. During the crushing process, a high-pressure water pump is connected to the hollow tube. The water pump operates to make water from the water source flow into the hollow tube and spray it out through the nozzles, thereby cleaning the blades and washing the plastic particles to remove surface impurities.
[0009] Preferably, a collection box is fixedly connected to the bottom end of the discharge pipe, a discharge port is opened on one side of the collection box, an inclined filter screen is installed on the collection box, and a drain pipe is connected to one side of the collection box. The crushed small particles and sewage will fall into the collection box through the discharge pipe. Under the action of the inclined filter screen, the sewage flows into the bottom of the collection box, and the small particles slide down along the inclined filter screen and are discharged through the discharge port, thereby realizing the separation and classified collection of small particles and water.
[0010] Preferably, a control panel is installed on the outer wall of the crushing box, and the control panel is used to control the start and stop of the motor and motor. When using the device, by setting the control panel, the start and stop of multiple drive devices can be centrally controlled together, which greatly improves the convenience of operation.
[0011] The advantages of this utility model are: 1. In the process of crushing PET composite materials, this utility model uses a motor to drive a rotating column to rotate a slitting blade and a cutting blade. The slitting blade can longitudinally cut the material into several segments, and the cutting blade can transversely cut the slitting material. By cyclically operating the two shearing methods, the material is crushed, which can effectively reduce the resistance in the cutting process, ensure the crushing effect, and reduce the crushing energy consumption. 2. In this utility model, the material to be crushed is placed into the feeding hopper during feeding. The motor operates to make the feeding roller rotate, thereby gradually feeding the material into the crushing box, realizing automated feeding. By adjusting the speed of the motor, the raw material is conveyed at an appropriate speed, avoiding material accumulation or blockage, ensuring uniform and continuous feeding, and providing a stable foundation for the subsequent crushing process. 3. When feeding materials, if the material thickness is uneven or the amount of material in the hopper changes, the spring force will drive the swing rod to swing up and down around the rotating rod, automatically adjusting the pressure between the feeding roller and the material surface, ensuring that the feeding roller is always in close contact with the material surface, and improving feeding efficiency.

During the T composite material crushing process, the material to be crushed is placed into the feed hopper 10. The motor 14 operates to make the feeding roller 15 rotate, thereby gradually feeding the material into the feed inlet 6 of the crushing box 1. The motor 4 is started, which makes the rotating column 5 drive the slitting blade 8 and the cutting blade 9 to rotate. The slitting blade 8 can longitudinally cut the material into several segments, and the cutting blade 9 can transversely cut the slitting material. The crushed small particles will fall to the bottom of the crushing box 1.

Support frames 16 are fixedly connected to the top of both sides of the feeding hopper 10. Three springs 17 are fixedly connected between the support frame 16 and the swing rod 12. During operation, before crushing the composite material, it is necessary to feed it. The material to be crushed is placed into the feeding hopper 10. The motor 14 operates, causing the feeding rollers 15 to rotate, thus gradually feeding the material into the crushing chamber 1, achieving automated feeding. By adjusting the speed of the motor 14, the raw material is conveyed at an appropriate speed, avoiding material accumulation or blockage, ensuring uniform and continuous feeding, and providing a stable foundation for the subsequent crushing process. When the material thickness is uneven or the amount of material in the feed hopper 10 changes, the elastic force of the spring 17 will drive the swing rod 12 to swing up and down around the rotating rod 11, automatically adjusting the pressure between the feeding roller 15 and the material surface, ensuring that the feeding roller 15 is always in close contact with the material surface, and improving the feeding efficiency. Please see Figure 3-4 As shown, fixing blocks 23 are fixed to both sides of the feed port 6. Hollow tubes 24 are installed on the two fixing blocks 23. Multiple nozzles 25 are connected to the hollow tubes 24. During operation, a high-pressure water pump is connected to the hollow tubes 24.

Please see Figure 2 As shown, a control panel 26 is installed on the outer wall of the crushing box 1, and the control panel 26 is used to control the start and stop of the motor 4 and the motor 14.

Working Principle: Existing PET composite material processing crushing equipment only uses a single shearing method, resulting in concentrated material deformation resistance during the cutting process. This requires greater power to complete the crushing, leading to high cutting resistance and high energy consumption. Therefore, a PET composite material processing crushing equipment is proposed to address these issues. During the PET composite material crushing process, the material to be crushed is placed in the feed hopper 10. The motor 14 operates, causing the feeding roller 15 to rotate, thereby gradually feeding the material into the feed inlet 6 of the crushing box 1. The motor 4 is started, causing the rotating column 5 to drive the slitting blade 8 and the cutting blade 9 to rotate. The slitting blade 8 can longitudinally cut the material into several segments, and the cutting blade 9 can transversely cut the slitting material. The crushed small particles fall to the bottom of the crushing box 1. Through the cyclical operation of the two shearing methods, the material is crushed, which can effectively reduce the resistance during the cutting process, ensure the crushing effect, and reduce crushing energy consumption. During feeding, the speed of motor 14 is adjusted to adapt the conveying speed of raw materials, avoiding material accumulation or blockage, ensuring uniform and continuous feeding, and providing a stable foundation for the subsequent crushing process. When the material thickness is uneven or the amount of material in the feed hopper 10 changes, the elastic force of the spring 17 will drive the swing rod 12 to swing up and down around the rotating rod 11, automatically adjusting the pressure between the feeding roller 15 and the material surface, ensuring that the feeding roller 15 is always in close contact with the material surface, and improving the feeding efficiency. During the crushing process, a high-pressure water pump is connected to the hollow tube 24. The water pump draws water from the water source into the hollow tube 24 and sprays it out through the nozzle 25, thereby cleaning the blades and washing the plastic particles to remove surface impurities. The crushed small particles and wastewater fall into the collection box 19 through the discharge pipe 18. Under the action of the inclined filter screen 20, the wastewater flows into the bottom of the collection box 19, and the small particles slide down along the inclined filter screen 20 and are discharged through the discharge port 21, thereby achieving the separation and classified collection of small particles and water.
