Synchronous cutting-off method for plastic particle forming

Abstract

The invention provides a synchronous cutting-off method for plastic particle forming. The method comprises the following steps that firstly, an input end of a material extruding mechanism is enabled to be connected with a plastic melting main machine through a butt joint disc at one end of a mounting cylinder, molten plastic inside the plastic melting main machine is pressurized through the plastic melting main machine and enters the input end of the material extruding mechanism through the butt joint disc, and the molten plastic is cooled and formed in the material extruding mechanism and isextruded into strip-shaped plastic and output from the output end of the material extruding mechanism; then, a driving device drives the material extruding mechanism to do stretchable movement in theextrusion direction of the plastic, the speed of the stretchable movement is equal to the plastic extrusion speed, and when the material extruding mechanism moves to the end point of the forward stretching movement, a cutting-off mechanism synchronously moves along with the material extruding mechanism and carries out granulation treatment on the extruded plastic; and finally, under the action ofthe driving device, the cutting-off mechanism is quickly reset, the material extruding mechanism does reverse retraction movement and enables the plastic to be extruded outwards at the double speed, and the operation is repeated, so that the cutting-off mechanism performs continuous granulation treatment on the extruded plastic.

Description

technical field

[0001] The invention relates to the technical field of plastic molding processing, in particular to a synchronous cutting method for molding plastic particles. Background technique

[0002] Plastic granulator is a kind of granulator, which is mainly used for processing plastic products such as waste plastic film, woven bag, agricultural convenience bag, pot, barrel, etc. It is one of the necessary processing machines for plastic recycling. At present, plastic granulator The machine mainly includes a plastic melting host and a multi-empty extrusion die that matches it. A rotatable blade is set at the extrusion port of the extrusion die, and the extruded strip plastic is pelletized through the rotation of the blade. The disadvantage is that From the moment the blade comes into contact with the extruded strip of plastic to the process of cutting off the section of plastic, the strip of plastic is still continuously extruding outward, causing the blade to cut the...
