[0002] Plastic bottles are very common in daily life. Drinking water and various beverage containers in life are contained in plastic bottles for easy sale. At the same time, used plastic bottles can be recycled and reused, saving resources while avoiding environmental pollution caused by the random discarding of plastics. After the plastic beverage bottles and plastic bottles used to hold various substances in life are recycled, the plastic will be decomposed through various equipment to form pure particles for recycling and reuse.

[0003] After plastic bottles are recycled, they will first pass through crushing and grinding equipment to crush the plastic bottle body and grind it into tiny plastic waste pieces.

[0026] A conveying motor 13 is fixed to one end of the discharge conveying pipe 1 connected to the crushing and grinding cylinder 2 , and the conveying motor 13 is drivingly connected to the rotating shaft at the center of the spiral conveying piece 4 .

[0027] The crushed plastic is screened by a crushing hole 8 provided on the inner side of the material blocking plate 7. The crushed plastic pieces that meet the crushing standards can be directly transported to the discharge conveying pipe 1 through the crushing hole 8. The crushing hole 8 is designed to be equidistantly enlarged, which allows the crushed plastic to be discharged evenly, thus ensuring the discharge efficiency.
