[0002] PVC plastic particles, also known as polyvinyl chloride particles, are a kind of plastic raw materials widely used in multiple industries. They are made from polyvinyl chloride resin through special processing techniques, with good physical properties and chemical stability. Due to their advantages such as weather resistance, chemical stability, electrical insulation, economy, and airtight performance, PVC particles have wide applications in many fields.

The anti-blocking feeding mechanism includes a feeding cylinder, a square feeding port, a square discharging port, a feeding cylinder, and a servo motor; the square feeding port and the square discharging port are respectively communicated and fixed at the top and bottom of the feeding cylinder, the feeding cylinder is rotatably arranged in the feeding cylinder, and a plurality of feeding grooves are arranged on the feeding cylinder at equal intervals in the circumferential direction; in the plastic particle feeding and packaging device of the utility model, through the arranged anti-blocking feeding mechanism, the servo motor is used to drive the feeding cylinder to rotate. When the feeding groove rotates to the upper part, the plastic particles fall into the feeding groove under the action of gravity. When the feeding groove rotates to the lower part, the plastic particles fall out of the feeding groove under the action of gravity and are discharged from the square discharging port, avoiding the occurrence of blocking accidents and being able to achieve quantitative feeding at the same time;

[0004] Under the elastic force of the telescopic spring in the above patent, when the plastic particles fall onto the buffer plate, the gravity will cause the buffer plate to turn downward, and the telescopic rod and the telescopic spring will contract.
