Forming Die of Plastic Pelletizer

Abstract

The invention provides a molding die head of a plastic granulator, which includes a docking device and a power device. The docking device includes a mounting cylinder, an annular docking plate coaxially fixedly connected with the opening at one end of the mounting cylinder, and coaxially fixed with the opening at the other end of the mounting cylinder. The connecting fixed ring and the mounting cylinder are provided with an extruding mechanism and a cutting mechanism. The extruding mechanism is connected to the plastic melting host through the docking plate, and under the action of the plastic melting host on the molten plastic pressure, it is formed by the extrusion mechanism. Strip extrusion, the extrusion mechanism can perform telescopic movement along the extrusion direction of the plastic and the telescopic speed is equal to the extrusion speed of the plastic, and the cutting mechanism performs pelletizing on the extruded plastic at the end of the extrusion movement of the extrusion mechanism , the power device is used to provide driving power for the extruding mechanism and the cutting mechanism, and when the extruding mechanism moves to the end point of the forward extension, the cutting mechanism is triggered to cut the extruded plastic.

Description

technical field [0001] The invention relates to the technical field of plastic molding processing, in particular to a molding die head of a plastic pelletizer. Background technique [0002] Plastic granulator is a kind of granulator, which is mainly used for processing waste plastic film (industrial packaging film, agricultural mulch film, greenhouse film, beer bag, handbag, etc.), woven bag, agricultural convenient bag, basin, barrel, beverage bottle , furniture, daily necessities, etc., suitable for most common waste plastics, is the most widely used, most widely used, and most popular plastic recycling processing machinery in the waste plastic recycling industry. At present, plastic pelletizers mainly include plastic melting hosts And the multi-empty extrusion die adapted to 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 the blade and the extr...

[0002] Plastic granulator is a kind of granulator, which is mainly used for processing waste plastic film (industrial packaging film, agricultural mulch film, greenhouse film, beer bag, handbag, etc.), woven bag, agricultural convenient bag, basin, barrel, beverage bottle , furniture, daily necessities, etc., suitable for most common waste plastics, is the most widely used, most widely used, and most popular plastic recycling processing machinery in the waste plastic recycling industry. At present, plastic pelletizers mainly include plastic melting hosts And the multi-empty extrusion die adapted to 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 the blade and the extruded From the moment the strips of plastic touch to the process of cutting the section of plastic, the strips of plastic are still continuously extruding outwards, causing the end face of the blade to cut the plastic pellets to be inclined and the texture of the plastic particles is uneven, which affects the For the subsequent processing of plastic granules, in order to overcome the above disadvantages, it is necessary to provide a plastic granule molding synchronous cutting head with ingenious structure, simple principle, convenient operation and use, which can make the cutting end of plastic granules flush and the plastic granules have uniform texture.
