Separating type plastic extruder

Abstract

The invention provides a separating type plastic extruder. The separating type plastic extruder comprises a molten plastic conveying device and an extruding machine head coaxially arranged at the discharging end of the molten plastic conveying device, the molten plastic conveying device is used for conveying molten plastic into the extruding machine head, the extruding machine head comprises a mounting machine head and a synchronous cutting device, the mounting machine head is coaxially mounted at the discharging end of the molten plastic conveying device, the mounting machine head is used forreceiving molten plastic and outputting the plastic in a soft solid strip structure, the synchronous cutting device is mounted on a mounting mechanism, and the synchronous cutting device is used forperforming particle cutting treatment on the soft solid strip plastic output through the mounting machine head. According to the separating type plastic extruder, the plastic fragments are sequentially subjected to melting, impurity filtering, conveying, strip-shaped forming and particle cutting to obtain the plastic particles, the cutting surfaces of the obtained plastic particles are also flat surfaces rather than inclined irregular surfaces, the size of the plastic particles is consistent, the quality is better, and subsequent sales are facilitated.

Description

technical field [0001] The invention relates to the field of plastic mechanisms, in particular to a plastic extruder. Background technique [0002] With the development of China's economy and the continuous advancement of science and technology, the scope of application of plastic granules is becoming wider and wider.

[0002] With the development of China's economy and the continuous advancement of science and technology, the scope of application of plastic granules is becoming wider and wider. The granulator is a molding machine that makes materials into specific shapes. At present, in the manufacturing process of plastic granules, most It needs to go through extrusion molding, wire drawing cooling and granulation processes, and finally through the packaging process to get the finished plastic granules. When plastic granules are granulated, sometimes the extruder and the granulator are directly connected together, and the plastic granules are processed through the granulator. The machine head directly cuts the plastic output from the extruder, but the cutting knife of the current granulator head will temporarily block the discharge end of the extruder during the cutting process of the granule plastic, which will cause The molten plastic accumulates in the extruder and exerts a large pressure on the wall of the extruder. In addition, because the cutting knife is in the process of cutting, the subsequent plastic will continue to be output, which will cause The cutting surface of the plastic granules is irregularly inclined, which greatly affects the quality of the plastic granules and directly affects the subsequent sales of the plastic granules. Therefore, it is necessary for the present invention to propose a plastic granule molding equipment, which sequentially processes the plastic granules. Melting, impurity filtering, conveying, strip forming, granule cutting and plastic granules are obtained. During the impurity filtering process, the impurities can be transported away by the auger after being blocked by the filter, so that the filter avoids frequent replacement and maintenance; the particle cutting process In the process, the strip-shaped plastic and the cutting knife move synchronously, that is, the two are in a relatively static state, so the cutting process is smooth and smooth, and the subsequent molten plastic will not cause blockage due to the cutting knife blocking the discharge hole. The cutting surface of the plastic pellets is also a flat surface rather than an inclined irregular surface, and the obtained plastic pellets are of the same size and better in quality, which is more convenient for subsequent sales
