Simultaneous cutting method for plastic pellet molding

Abstract

The invention provides a synchronous cutting method for molding plastic granules, the steps of which are as follows: first, the input end of the extruding mechanism is connected to the plastic melting main machine through the docking plate at one end of the installation cylinder, and the plastic melting main machine melts the inside The plastic in the state is pressurized and enters the input end of the extrusion mechanism through the docking plate, and the molten plastic is cooled and formed in the extrusion mechanism and extruded into a strip of plastic from its output end; then, the driving device will drive the extrusion mechanism along the extrusion of the plastic. The telescopic movement is performed in the outgoing direction and the speed of the telescopic movement is equal to the speed of plastic extrusion. When the extrusion mechanism moves to the end of the forward movement, the cutting mechanism moves synchronously with the extrusion mechanism and performs pelletizing on the extruded plastic. ;Finally, under the action of the driving device, the cutting mechanism resets quickly, and the extruding mechanism performs a reverse retraction movement and makes the plastic extrude outward at twice the speed. Continuous cutting process.

Description

technical field [0001] The invention relates to the technical field of plastic molding and processing, in particular to a synchronous cutting method for plastic particle molding. Background technique [0002] Plastic pelletizer is a pelletizer, mainly used for processing waste plastic films, woven bags, agricultural convenience bags, basins, barrels and other plastic products. It is one of the necessary processing machines for plastic recycling. At present, plastic pelletizing The machine mainly includes a plastic melting host and a multi-hole extrusion die adapted to it. A rotatable blade is set at the extrusion mouth of the extrusion die, and the extruded strip plastic is pelletized by the rotation of the blade. The disadvantage is that , the moment the blade is in contact with the extruded strip of plastic to the process of cutting the section of plastic, the strip of plastic is still continuously extruded outward, so that the end face of the blade to the plastic pellets ...

AI Technical Summary

Problems solved by technology

[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 end face of the plastic pellets into an inclined plane and the plastic pellets Inhomogeneous texture affects the subsequent processing of plastic granules. In order to overcome the above disadvantages, it is necessary to provide a plastic granule with ingenious structure, simple principle, convenient operation and use, which can make the cut ends of plastic granules flush and uniform in texture.
