[0049] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0050] like Figures 1 to 7 As shown, the grinding device for plastic particle production and processing of this utility model includes:

[0051] Material feeding bracket 1 is fixedly installed on the ground;

[0052] Grinding mechanism 2 is fixedly installed on the ground and is used to grind plastic particles;

[0053] A quantitative feeding mechanism is installed on the feeding support 1 and is used to provide the blank material of plastic particles to the grinding mechanism 2;

[0054] The quantitative feeding mechanism includes:

[0055] The storage hopper 11 is fixedly installed on the feeding bracket 1. The bottom end of the storage hopper 11 is provided with a feeding port for storing materials.

[0056] The transfer box 12 is fixedly installed on the discharge port of the storage hopper 11. The top of the transfer box 12 is provided with a transition port, which is connected to the discharge port.

[0057] The discharge block 13 is horizontally slidably installed in the transfer box 12, and a material storage trough is provided on the discharge block 13; the material storage trough is eccentrically set on one side of the discharge block 13, and the other side of the discharge block 13 is set as a solid plane;

[0058] The working process and principle of the device are as follows: Plastic particles are stored in the storage hopper 11; when feeding is required, the storage trough of the discharge block 13 moves below the transition port of the transfer box 12, and the plastic particles in the storage hopper 11 fall into the storage trough through the discharge port and the transition port; by precisely controlling the sliding distance and frequency of the discharge block 13, the number of plastic particles in the storage trough can be adjusted to achieve quantitative feeding; when the number of plastic particles in the storage trough reaches the preset amount, the discharge block 13 slides above the grinding mechanism 2, and the plastic particles in the storage trough are released into the grinding mechanism 2 for processing; the grinding mechanism 2 performs fine grinding on the plastic particles; the above process is repeated to ensure that the number of plastic particles ground each time is stable, thereby improving grinding efficiency and product quality; the storage hopper 11 serves as a material storage container for storing particles to be ground. The material consists of plastic particle blanks; the material sinks naturally to the bottom discharge port in the storage hopper under the action of gravity; the transfer box 12 connects to the discharge port of the storage hopper, serving as a transition, and has a horizontally sliding discharge block 13 installed inside; the trough on the discharge block is designed with an eccentric structure, and when the discharge block slides horizontally in the transfer box, the trough will periodically receive a certain amount of plastic particles from the discharge port below the storage hopper; each time the discharge block moves to a specific position, the material in the trough will be released into the grinding mechanism, thereby achieving precise quantitative feeding; since the amount of material fed each time is fixed, it can effectively avoid the problem of overloading the grinding machine due to too much material being fed at once; at the same time, the uniform feeding method also reduces the impact on the grinding equipment, reduces wear, and extends the service life of the equipment.

[0059] like Figures 5 to 7 As shown, the polishing mechanism 2 includes:

[0060] The grinding bracket 21 is fixedly installed on the ground;

[0061] The transmission box 22 is fixedly mounted on the grinding bracket 21;

[0062] The discharge cylinder 23 is fixedly installed on the transmission box 22 and has an internal cavity;

[0063] The grinding screen plate 24 is fixedly installed on the discharge cylinder 23. The grinding screen plate 24 is provided with a number of screen holes, and the top surface of the grinding screen plate 24 is set as a frosted surface.

[0064] The grinding cylinder 25 is fixedly installed on the grinding sieve plate 24, and a grinding chamber is provided inside it;

[0065] The receiving hopper 26 is connected to the grinding cylinder 25 and is used to receive the blank material of plastic particles and guide the blank material of plastic particles into the grinding cylinder 25.

[0066] The rotating shaft 27 is rotatably mounted on the transmission box 22, and the rotating shaft 27 is rotatably disposed in the discharge cylinder 23, the grinding screen plate 24 and the grinding cylinder 25;

[0067] The grinding frame 28 is fixedly mounted on the top of the rotating shaft 27;

[0068] Both grinding wheels 29 are rotatably mounted on the grinding frame 28;

[0069] Transmission assembly for driving the rotating shaft 27 to rotate;

[0070] The working process and principle of the grinding mechanism 2 are as follows: The quantitative feeding mechanism guides a preset number of plastic particle blanks into the grinding cylinder 25 through the receiving hopper 26; the transmission component is activated, driving the rotating shaft 27 and the grinding frame 28 and grinding wheel 29 fixed on it to start rotating; when the plastic particles enter the grinding cylinder 25, they come into contact with the rotating grinding wheel 29 and the abrasive surface of the grinding screen plate 24 for fine grinding; the ground plastic particles are discharged through the screen holes of the grinding screen plate 24 to the discharge cylinder 23, while larger particles or particles that are not completely ground continue to be ground in the grinding cylinder 25; the grinding process continues until all plastic particles achieve the expected grinding effect; finally, the ground plastic particles are discharged from the discharge cylinder 23 for subsequent collection and processing; the grinding mechanism 2 achieves high-quality grinding of plastic particles through precise quantitative feeding, efficient transmission drive, multi-stage grinding processing, and meticulous screening and discharge.

[0071] like Figures 5 to 6 As shown, the transmission assembly includes:

[0072] Driven gear 2a is located inside transmission housing 22 and is fixedly mounted on the bottom end of rotating shaft 27;

[0073] The driving gear 2b is rotatably mounted inside the transmission box 22, and the driving gear 2b meshes with the driven gear 2a.

[0074] Motor 2c is fixedly mounted on the grinding bracket 21 and is used to drive the drive gear 2b to rotate;

[0075] The working process and principle of the transmission component are as follows: When the motor 2c starts, its output shaft begins to rotate; the output end of the motor 2c is connected to the drive gear 2b, so the drive gear 2b will rotate with the rotation of the motor 2c; the rotation of the drive gear 2b will drive the driven gear 2a and the shaft 27 connected to it to rotate together through meshing with the driven gear 2a, which can ensure accurate power transmission and stable speed; as the shaft 27 rotates, the grinding frame 28 and the two grinding wheels 29 fixedly mounted on its top will also rotate; when the plastic particles enter the grinding chamber of the grinding cylinder 25, they will come into contact with the rotating grinding wheels 29 and be subjected to grinding action; after the fine grinding by the grinding wheels 29, the surface quality of the plastic particles is improved; at the same time, due to the stability and efficiency of the transmission component, the continuity and uniformity of the grinding process are ensured, thereby improving grinding efficiency and product quality.

[0076] like Figure 6 As shown, the polishing mechanism 2 also includes:

[0077] The collar 2d is located inside the discharge cylinder 23 and is securely fitted onto the rotating shaft 27.

[0078] Two levers 2e are symmetrically fixed on the collar 2d and rotate inside the discharge cylinder 23;

[0079] When motor 2c starts and drives the drive gear 2b to rotate, the drive gear 2b meshes with the driven gear 2a, thereby driving the rotating shaft 27 to rotate. The rotation of the rotating shaft 27 in turn drives the collar 2d and the lever 2e fixed on the collar 2d to rotate together. The plastic particle blank falls into the discharge cylinder 23. At this time, the rotating lever 2e will contact the material, and through the action of stirring, it helps the material to be distributed more evenly in the discharge cylinder 23, preventing the discharge cylinder 23 and the grinding screen plate 24 from clogging. During long-term operation, the material may clog the screen holes or discharge channel due to accumulation or adhesion. The rotation of the lever 2e can periodically break up these accumulations and adhesions, thereby keeping the discharge channel unobstructed and improving grinding efficiency.

[0080] like Figures 5 to 6As shown, a discharge guide 2f is fixedly installed on the discharge cylinder 23. As the grinding process continues, more and more ground plastic particles accumulate in the cavity of the discharge cylinder 23. At this time, the discharge guide 2f serves as an outlet channel to discharge the accumulated material. When the material in the discharge cylinder 23 accumulates to a certain extent, or when the grinding process ends, the material is discharged through the discharge guide 2f. Since the discharge guide 2f is connected to the inside of the discharge cylinder 23, and its design usually takes into account the flowability and discharge efficiency of the material, the material can be smoothly discharged from the discharge cylinder 23 through the discharge guide 2f. The discharge guide 2f allows the ground plastic particles to be discharged in a timely manner, avoiding excessive accumulation of material in the discharge cylinder 23, thereby improving grinding efficiency. The material discharged through the discharge guide 2f is more concentrated and orderly, facilitating subsequent collection, classification, or packaging processes.

[0081] like Figures 2 to 3 As shown, the quantitative feeding mechanism also includes:

[0082] Cylinder support 14 is fixedly installed on unloading bracket 1;

[0083] Cylinder 15 is fixedly mounted on cylinder support 14;

[0084] The cylinder locking block 16 is fixedly installed on the discharge block 13 and is used to connect the discharge block 13 and the cylinder rod of the cylinder 15.

[0085] When a certain amount of plastic particle blanks needs to be supplied to the grinding mechanism 2, the cylinder 15 receives a control signal and starts to move; it drives the cylinder rod to retract, and as the cylinder rod retracts, the cylinder locking block 16 drives the discharge block 13 to slide horizontally in the transfer box 12; since the storage trough is eccentrically set on one side of the discharge block 13, when the discharge block 13 slides to a certain position, the storage trough will be aligned with the discharge port of the storage hopper 11 and the transition port of the transfer box 12. At this time, the material can enter the storage trough from the storage hopper 11 through the discharge port and the transition port; when a sufficient amount of plastic particle blanks accumulate in the storage trough, the material in the storage trough is the quantitative material required for one grinding; next, it drives the cylinder rod to extend, causing the discharge block 13 to slide outward, releasing the material in the storage trough into the receiving hopper 26, and then into the grinding cylinder 25 for grinding; by controlling the extension length or time of the cylinder 15, the amount of material fed each time can be precisely controlled, thereby achieving quantitative feeding.

[0086] like Figure 3As shown, two guide rods 17 are symmetrically fixed on the discharge block 13, and both guide rods 17 are slidably inserted into the cylinder support 14. During the sliding process of the discharge block 13, the guide rods 17 play a key guiding and supporting role. They ensure that the discharge block 13 can slide smoothly along the predetermined path without deviation or shaking, thereby improving the accuracy and reliability of quantitative feeding.

[0087] like Figure 3 As shown, limit blocks 18 are fixedly installed at the ends of both guide rods 17; the limit blocks 18 ensure that the guide rods 17 will not accidentally come out of the sliding track, thereby avoiding equipment damage or personal injury caused by the uncontrolled discharge block 13; by limiting the sliding range of the discharge block 13, the limit blocks 18 ensure the stability and accuracy of the quantitative feeding mechanism, thereby improving grinding efficiency and product quality.

[0088] The grinding device for plastic particle production and processing of this utility model can be installed, connected or set in a common mechanical way, and can be implemented as long as it can achieve its beneficial effect.

[0089] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
