Description

Technical Field

[0001] The present application relates to the technical field of polyester yarn production, and in particular to a pulverizing device for polyester yarn production and processing. Background Art

[0002] At present, polyester is an important variety of synthetic fibers and is the trade name of polyester fiber in my country. It is a fiber-forming polymer made by esterification or ester exchange and polycondensation reaction of purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) as raw materials: polyethylene terephthalate (PET), and fibers made by spinning and post-processing. Polyester silk products are mainly suitable for coated yarns, socks, yarns, gloves, carpets, curtains and other fields. In the production process of polyester silk, recycled plastic bottles need to be crushed many times. The existing crushing devices are divided into multiple separate crushers, which need to be poured out and loaded many times, resulting in low crushing efficiency and increased workload for workers.

[0007] By adopting the above technical scheme, the plastic products to be crushed can be put into the first crushing box, and after preliminary crushing in the first crushing box, they enter the second crushing box. Driven by the second rotating motor, the rotating shaft rotates, driving the two crushing knife shafts to rotate to crush the plastic. The top crushing knife shaft crushes the plastic to a suitable size through the first sieve plate with larger holes and enters the bottom crushing knife shaft. Under the action of the bottom crushing knife shaft, it is crushed again, and the crushed plastic particles fall out through the second sieve plate.

[0015] Preferably, the fixed plate is fixedly connected to the rotating shaft, and both sides of the top of the push plate are arranged in an arc shape.

[0016] By adopting the above technical solution, direct pushing of plastic particles stuck on the first sieve plate and the second sieve plate is avoided, and the arc shape plays a certain role in buffering.

[0017] Preferably, a discharge port is fixedly connected to the bottom of the second crushing box.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

[0019] 1. The arrangement of the first crushing component and the second crushing component is conducive to putting the plastic products to be crushed into the first crushing box. After the initial crushing in the first crushing box, the plastic products enter the second crushing box. The two crushing blade shafts rotate to crush the plastic. The plastic crushed by the top crushing blade shaft to a suitable size passes through the first sieve plate with larger holes and enters the bottom crushing blade shaft.
