Problems solved by technology

[0002] The existing plastic extruder is a commonly used plastic processing equipment, and the screw extruder is the most commonly used mixed molding equipment. The head is injected into the mold for cooling and molding, and it cannot be completely melted to the molten state during the actual heating process of the hot melt cavity, resulting in solid particles in the molten polystyrene extruded from the extrusion head, which affects the quality of injection molding and reduces the finished product Mechanical properties, destroying the integrity of injection molding
Long-term operation will cause production pressure on the extruder and shorten the life of the extruder. For this reason, we propose a crushing plastic extruder

Abstract

The invention discloses a crushing type plastic extruder. A main crushing device is composed of a motor, a first rotating shaft, a driving gear, a plurality of first stirring blades and a pressing plate. The motor is installed on the middle part of the upper end of a box body, the output end of the motor is connected with the first rotating shaft, and the other end of the first rotating shaft penetrates through the top wall of the box body and reaches the inside of an extrusion device. The multiple first stirring blades are connected to the side wall of the section, located in the box body, ofthe first rotating shaft at equal distances in the circumferential direction. The extrusion device includes an extrusion box, a filter plate and a spiral rod. The upper end of the extrusion box fixedly penetrates through the middle part of the lower end of the box body. The upper end of the inner side wall of the extrusion box is fixedly connected with the filter plate. The spiral rod is movablyconnected to the filter plate in an inserted mode, and the upper end of the spiral rod is fixedly connected with the lower end of the first rotating shaft. The crushing type plastic extruder has the characteristics that the crushing effect is good and the work efficiency is improved, and is high in practicability.

Description

technical field [0001] The invention relates to the field of extruders, in particular to a pulverizing plastic extruder. Background technique [0002] The existing plastic extruder is a commonly used plastic processing equipment, and the screw extruder is the most commonly used mixed molding equipment. The head is injected into the mold for cooling and molding, and it cannot be completely melted to the molten state during the actual heating process of the hot melt cavity, resulting in solid particles in the molten polystyrene extruded from the extrusion head, which affects the quality of injection molding and reduces the finished product Mechanical properties, destroying the integrity of injection molding. Long-term operation will cause production pressure on the extruder and shorten the life of the extruder. Therefore, we propose a crushing plastic extruder. Contents of the invention [0003] The object of the present invention is to provide a crushing type plastic extr...
