Description

Technical Field

[0001] The utility model relates to the technical field of plastic crushers, in particular to a recycling mechanism for a plastic crusher. Background Art

[0002] The plastic crusher uses an electric motor to drive the moving blade disc to rotate at high speed, thereby crushing large pieces of plastic. The crushed plastic is filtered and output according to the size of the plastic particles. However, the existing plastic crusher's screen will directly discharge the plastic fragments that meet the subsequent processing requirements for standby use after screening the crushed plastic fragments, while the plastic fragments that do not meet the requirements need to be manually collected and then put into the crusher for secondary crushing. The efficiency of manual secondary feeding is low and the labor cost is increased, and the practicality is poor.

[0003] CN 219235847 U discloses a recycling mechanism for a recycled plastic crusher, comprising a crusher body, a secondary screening feed base fixedly installed at the bottom of the crusher body, a curved feed hopper fixedly connected to one side of the top of the crusher body, and a negative pressure recovery component fixedly connected to the other side of the top of the crusher body. In the above scheme, waste plastic products enter the inner cavity of the crusher body through the curved feed hopper, and four groups of crushing rollers installed in the inner cavity of the crusher body rotate counterclockwise at high speed under the drive of an external driver to perform rotary cutting and crushing on the plastic products, and the crushed plastic fragments fall on the self-vibrating screen plate for screening, and qualified fragments are concentrated and fall into the secondary screening feed base for standby use, and unqualified fragments are secondary-discharged through the negative pressure recovery component. By setting the negative pressure recovery component to replace manual secondary discharging and crushing of unqualified plastic fragments, the crushing efficiency of waste plastic products is greatly improved.

[0004] However, when the above scheme uses the negative pressure recovery component to re-discharge the unqualified fragments, the plastic fragments are sucked into the negative pressure extraction box through the suction pipe. When the plastic fragments are large, the suction pipe is prone to blockage, affecting the normal use of the equipment. Utility Model Content
