Plastic granulation device capable of conveniently adjusting particle size

Abstract

The invention discloses a plastic granulation device capable of conveniently adjusting the particle size. The plastic granulation device comprises a compression cavity, wherein the compression cavityis of a pipe-shaped structure with through holes formed in two ends; a feeding hopper is arranged at the top end of the compression cavity; in an extrusion process, when a compression piston is used for pushing plastic to one end of a granulation disc, a heating pipe is used for heating the plastic in the compression piston and the plastic is convenient to extrude; when an extruded plastic strip passes through a through hole of the granulation disc, a motor drives a cutting-off disc and a cutting-off knife to rotate under the supporting of a motor retainer, and then the extruded plastic stripis cut off and plastic granulation is realized; the cutting-off knife and the cutting-off disc are tightly matched through a mounting groove and can be detached; when the length of cutting off the plastic strip needs to be adjusted, only the quantity of the cutting-off knives mounted on an outer ring of the cutting-off disc needs to be changed, the cutting-off frequency can be changed and the change of cutting-off length is realized; cut-off plastic falls into a collection cabin and the collection cabin is provided with a pull type cabin door and plastic grains are conveniently subjected to next-step treatment; the design of the device is more humanized and the device is easy to popularize and apply.

Description

technical field [0001] The invention relates to the technical field of plastic granulation equipment, in particular to a plastic granulation device capable of conveniently adjusting the particle size. Background technique [0002] At present, the processing of construction plastic products in my country is largely based on plasticizing construction plastic powder and then processing it into shape. The extruder is the most widely used equipment in polymer processing. After the polymer is mixed with various additives, it is sent into the extruder to be melted, and further mixed evenly. After passing through the multi-hole die, multiple strips are formed, and then made into Granules, but the traditional basic mechanism does not have the function of adjusting the length of the extruded strip, or it is inconvenient to adjust the length of the extruded strip. Therefore, we propose a plastic granulator that can easily adjust the particle size to solve the above problems. Contents...
