Description

TECHNICAL FIELD

[0002] With the continuous growth of plastic consumption, the recycling of plastic waste has become a key measure to alleviate resource shortage and environmental pollution. In the process of plastic recycling, crushing is the core link to realize efficient recycling of plastic materials, and the performance of the processing device directly affects the recycling efficiency, energy consumption and the quality of the subsequent regenerated products.

[0003] The existing plastic recycling processing device mainly crushes plastic waste through a crusher. However, the feeding system of the existing processing device usually directly feeds plastic waste into the main body of the crusher. However, such plastic containers are usually sealed, and there is air or liquid inside. During the crushing process, the sealed container is easily broken in an "explosive" manner when it is squeezed, which not only causes plastic fragments to splash, increasing equipment wear and safety risks, but also reduces the crushing efficiency due to uneven stress. In addition, directly feeding plastic waste into the crusher cannot dynamically adjust the feeding speed according to the real-time processing capacity of the crusher. When the feeding rate is too fast, the crusher is prone to jamming or shutdown due to overload. When the feeding rate is too slow, the utilization rate of the equipment is low, causing energy waste.

S2.3: When the discharge speed range threshold of the guide plate is greater than the required feeding speed of the main body of the crusher, the guide plate is pushed up and rotated by one unit angle by the drive cylinder, that is, the discharge speed between the two guide plates is reduced, and the discharge speed range threshold of the guide plate is compared with the required feeding speed of the main body of the crusher again until the discharge speed range threshold of the guide plate matches the required feeding speed of the main body of the crusher. S2.4: When the discharge speed interval threshold of the guide plate is less than the demand feeding speed of the main body of the crusher, the guide plate is pushed down to rotate by a unit angle by the driving cylinder, that is, the discharge speed between the two guide plates is increased, and the discharge speed interval threshold of the guide plate at this time is compared with the demand feeding speed of the main body of the crusher again, until the discharge speed interval threshold of the guide plate matches the demand feeding speed of the main body of the crusher, so as to make the feeding roller uniformly convey the plastic to the inside of the main body of the crusher.
