Screening waste plastic shredder

Abstract

The invention discloses a screening type waste plastic crushing machine which comprises a machine frame. A crushing chamber is fixed to the machine frame and connected with a feeding channel. An opening is formed in the crushing chamber. The opening is slidably connected with an adjusting plate. The crushing chamber is connected with a first air inlet pipe. The first air inlet pipe is connected with an adjusting pipe and an air delivery mechanism. The air delivery mechanism is provided with a cooler. The adjusting plate is slidably connected in the adjusting pipe. A reciprocating pushing device is arranged between the feeding channel and a material delivery pipe. The reciprocating pushing device is slidably connected in an output pipe. The first air inlet pipe is connected with an intermittent air delivery pipe. The intermittent air delivery pipe communicates with the output pipe. The intermittent air delivery pipe is slidably connected with a communicating plate. A ventilation hole is formed in the communicating plate. A through hole is formed in the intermittent air delivery pipe. The communicating plate is connected with an insertion rod. An oblique plate is arranged on the side wall of the feeding channel. According to the screening type waste plastic crushing machine, through the arrangement of the reciprocating pushing device, the oblique plate cooperating with the reciprocating pushing device, the crushing chamber, a first ventilation pipe and the air delivery mechanism, the crushing quality is improved, and subsequent steps are reduced.

Description

technical field [0001] The invention relates to the mechanical field of crushing plastics, in particular to a screening type waste plastic crusher. Background technique [0002] At present, most of the plastic recycling process requires the use of crushers, and the recycled plastics must be put into the crusher to be broken into small particles before further processing. A traditional crusher generally includes a crusher working room, a crushing motor knife installed at the bottom of the crusher working room, a fixed knife set opposite to the crusher machine knife, a feeding port set on the upper part of the crusher working room, and a crusher located under the crusher knife. The discharge mesh plate. During the crushing process of the traditional crusher, the bulk plastic will roll up and down in the crusher working room, and the residence time is long, so it cannot be broken into small particles quickly, and the crushing efficiency is low, which seriously affects the outp...

Problems solved by technology

[0004] The above solution solves the problem of low work efficiency in the prior art, but there are still certain problems. 1. After the waste plastics are crushed, the waste plastics need to be stored for use, and the heated waste clinker is discharged from the crushing chamber At this time, the operator needs to cool the plastic before it can be sent into the storage bin, which increases the follow-up steps, prolongs the operation time, and increases the labor intensity; 2. After the plastic is heated, the plastic becomes soft and the viscosity increases , when using the cutter head to cut plastic, the cutter head is easy to stick to the plastic, and the sticky cutter head will not be able to cut the plastic in the next cutting, which will lead to the waste plastic cutting broken particles Different diameters, lower crushing quality
