The right side plate 32... An installation assembly 36 is installed on the right side. The crushing assembly 5 includes a drive motor 51. A rotating shaft 52 is fixedly connected to the left end of the main shaft of the drive motor 51. A first sealing member 53, which is bolted to the right side plate 32, is rotatably connected to the rightmost end of the outer side of the rotating shaft 52. A second sealing member 54, which is bolted to the left side plate 31, is rotatably connected to the leftmost end of the outer side of the rotating shaft 52. A set of triangular turntables 55 are sleeved on the outer side of the rotating shaft 52.

[0029] A feeding bin 2 is installed on the lower side of the main frame 1, a crushing bin 3 is installed on the upper side of the main frame 1, and a feeding bin 4 is installed on the upper side of the crushing bin 3. A crushing component 5, partially located within the crushing bin 3, is located on the upper side of the main frame 1. The main frame 1 consists of a mounting frame and a set of universal locking wheels. The feeding bin 2 consists of a receiving hopper and a suction pipe. The right end of the suction pipe of the feeding bin 2 is fixedly connected to the left end face of the receiving hopper, and the right end of the suction pipe of the feeding bin 2 communicates with the receiving hopper. The feeding bin 4 consists of a feeding hopper and a bent guide bin with a viewing window. The left and right side plates 32 of the drive motor 51 are detachably connected. Through the feeding bin 4, [the following can be observed / connected]. Feeding is performed, and material can be collected through the feeding hopper 2. The upper ends of the left side plate 31, right side plate 32, rear side plate 33, and front side plate 34 are aligned, and the lower end of the right side plate 32 is aligned with the lower end of the left end plate of the lower screen plate 35. The back sides of the rear side plate 33 and the front side plate 34 are slidably connected to the main frame 1. The upper side of the mounting component 36 is detachably connected to the feeding hopper 4. The left end plates of the left side plate 31, right side plate 32, rear side plate 33, front side plate 34, and lower screen plate 35 can cooperate with the first sealing component 53 and the second sealing component 54 to form a hopper with openings at both the top and bottom, allowing the crushed plastic and crushing blades 56 to be fed. Full contact; the upper end of the left end plate of the lower screen plate 35 and the lower end of the left side plate 31 are tightly fitted together. The curved screen plate of the lower screen plate 35 is tightly fitted with the right side plate 32, the rear side plate 33, and the front side plate 34 respectively. The triangular turntable 55 and the crushing blade 56 are both located above the curved screen plate of the lower screen plate 35. The plastic to be crushed can be screened through the lower screen plate 35. Only plastic particles that are crushed into particles with the required particle size can pass through the screen holes of the lower screen plate 35 and fall into the feed bin 2. The triangular turntable 55 is provided with three circumferentially distributed blade mounting protrusions. The triangular turntable 55 is tightly fitted in the left and right directions. The blade mounting protrusions of multiple triangular turntables 55 are staggered in a stepped manner and arranged in a "V" shape. The staggered and arranged "V" shaped crushing blades 56 can more fully grasp the plastic to be crushed and prevent the plastic to be crushed from sticking to the left side plate 31, right side plate 32, rear side plate 33, and front side plate 34. The triangular turntables 55 are provided with limiting slots in the middle, and the rotating shaft 52 is provided with limiting blocks on the outside. The limiting slots of the triangular turntables 55 are matched with the shape of the limiting blocks of the rotating shaft 52. The rotating shaft 52 can drive the triangular turntables 55 and the crushing blades 56 to rotate synchronously.

[0030] Workflow: Before use, place the main frame 1 in a suitable position and connect the power supply. This device is equipped with an external controller, which is electrically connected to the drive motor 51. The external controller can be manually operated to adjust the operating status of the drive motor 51. This device needs to be used in conjunction with a negative pressure material receiving device. All of the above are existing technologies. When using this device, the operator first uses the external controller to make the drive motor 51 rotate at a low speed. The drive motor 51 can drive the rotating shaft 52 to rotate, which in turn drives the triangular turntable 55 and the crushing blade 56 located between the first sealing member 53 and the second sealing member 54 to rotate synchronously. Then, the operator feeds the material from above the feeding bin 4. After the crushed plastic enters the crushing bin 3 from the feeding bin 4, The left end plates of the left side plate 31, right side plate 32, rear side plate 33, front side plate 34, and lower screen plate 35 can cooperate with the first sealing member 53 and the second sealing member 54 to form a chamber with openings at both the top and bottom. The rotating triangular turntable 55 can drive the crushing blades 56 to cut the plastic. Each triangular turntable 55 is provided with three blade mounting protrusions, and each triangular turntable 55 can install three crushing blades 56. Therefore, the crushing blades 56 can form three cutting paths in the left and right directions. Since the blade mounting protrusions of the triangular turntable 55 are staggered in a stepped manner and arranged in a "V" shape, the cutting path formed by the crushing blades 56 is stepped. The crushing blades 56 can more fully grasp the plastic to be crushed and prevent the plastic to be crushed from sticking to the left side plate 31, right side plate 32, rear side plate 33, and front side plate 34. After the plastic to be crushed is cut by the crushing blades 56, it can pass through the lower screen plate 35. Screening is performed, and only plastic particles crushed to the required particle size can pass through the screen holes of the lower screen plate 35 and fall into the feeding bin 2. The negative pressure receiving device can be composed of an exhaust fan and a receiving box with a filter baffle using existing technology. The negative pressure receiving device can create a negative pressure in the receiving box by the exhaust fan, which can suck the plastic particles in the feeding bin 2 into the receiving box of the negative pressure receiving device. At the same time, the filter baffle on the receiving box prevents the plastic particles from being sucked into the exhaust fan. The crushing bin 3 of this device is located between the feeding bin 2 and the feeding bin 4. The lower screen plate 35 is detachably connected to the rear side plate 33 and the front side plate 34 respectively. If the device needs to be inspected or maintained, the staff only needs to remove the lower screen plate 35 between the rear side plate 33 and the front side plate 34 to inspect the triangular turntable 55 and the crushing blade 56 located inside the crushing bin 3 without disassembling other parts. This method is relatively simple and quick.The device drives the triangular turntable 55 and the crushing blades 56 to rotate synchronously via a rotatable rotating shaft 52. The triangular turntable 55 and the crushing blades 56 cut and crush the plastic to be crushed. The three sets of crushing blades 56 arranged in a "V" shape can more effectively grip the plastic, preventing it from sticking to the left side plate 31, right side plate 32, rear side plate 33, and front side plate 34. This ensures the plastic is thoroughly shredded, effectively improving the crushing efficiency of the crusher. Simultaneously, it avoids excessive friction between the plastic and the left side plate 31, right side plate 32, rear side plate 33, and front side plate 34, thus extending the service life of the crushing chamber 3.
