Simultaneous cut-off member for plastic foam molding

Abstract

The invention provides a synchronous cutting member for plastic foam molding, which includes a mounting cylinder (110), an annular docking plate (111) coaxially fixedly connected with the opening of one end of the mounting cylinder (110), and another A fixed ring (112) with one end open and coaxially fixedly connected, and an extruding mechanism (120) and a cutting mechanism (130) are arranged on the installation cylinder (110). The extruding mechanism (120) connects with the plastic melting main machine The connection is connected and under the action of the plastic melting host on the molten plastic, it is extruded in strips from the extrusion mechanism (120), and the extrusion mechanism (120) can perform telescopic movement along the extrusion direction of the plastic and stretch The speed is equal to the extrusion speed of the plastic, and the cutting mechanism (130) cuts the extruded plastic at the end of the forward movement of the extrusion mechanism (120). The texture of the plastic pellets is uniform.

Description

technical field [0001] The invention relates to the technical field of plastic molding, in particular to a synchronous cutting member for plastic foam molding. Background technique [0002] The molding of plastic granules mainly includes two stages, one is to melt the waste plastic, the other is to extrude the molten plastic into strips and cut the extruded plastic. The extrusion and cutting are carried out synchronously and continuously to ensure that the plastic The processing efficiency of granule molding. At present, the plastic granulator mainly includes a plastic melting host and a multi-empty extrusion die adapted to it. A rotatable blade is set at the extrusion port of the extrusion die, and the extrusion is controlled by the rotation of the blade. Strip plastics are pelletized. The problem is that the strip plastic is still continuously extruding from the moment the blade contacts the extruded strip plastic to the process of cutting the section of plastic, causing t...

Problems solved by technology

[0002] The molding of plastic granules mainly includes two stages, one is to melt the waste plastic, the other is to extrude the molten plastic into strips and cut the extruded plastic. The extrusion and cutting are carried out synchronously and continuously to ensure that the plastic The processing efficiency of granule molding. At present, the plastic granulator mainly includes a plastic melting host and a multi-empty extrusion die adapted to it. A rotatable blade is set at the extrusion port of the extrusion die, and the extrusion is controlled by the rotation of the blade. Strip plastics are pelletized. The problem is that the strip plastic is still continuously extruding from the moment the blade contacts the extruded strip plastic to the process of cutting the section of plastic, causing the blade to The end face of the plastic granulation is inclined and the texture of the plastic granules is uneven, which affects the subsequent processing of the plastic granules. In order to overcome the above-mentioned disadvantages, it is necessary to provide a cutting machine with ingenious structure, simple principle, convenient operation and use, which can make the plastic granules cut. Simultaneous cut-off component for plastic pellet molding with flush ends and uniform pellet texture
