Description

Technical Field

[0001] This utility model relates to the field of PE granule processing technology, specifically to a raw material granulator for PE granule processing. Background Technology

[0002] PE granules are a common type of plastic granules, usually white or colorless transparent granules with regular shape and uniform size; they have low density, moderate hardness, and a certain degree of flexibility, making them not easily broken; they are chemically stable and do not easily react with other substances at room temperature, have good chemical corrosion resistance, and can withstand the erosion of most acids and alkalis, but are not resistant to strong oxidizing acids.

[0003] The processing requires a polymerization reaction. The resulting polyethylene resin is then extruded and pelletized into granules. In the basic process, the resin melts at high temperature and is uniformly mixed and plasticized by the screw and shearing action of the extruder. It is then extruded through a die of a specific shape and finally cooled and pelletized to obtain PE granules. In the existing technology, pelletizing is carried out by a set of symmetrical rotating blades. During long-term operation, the continuous extrusion contact between the blades and the raw material easily causes blade wear or debris to adhere to the blade surface, requiring machine shutdown for maintenance. This not only involves cumbersome maintenance procedures but also reduces work efficiency, indicating room for technological improvement. Utility Model Content

[0004] This invention aims to solve the aforementioned technical problem that the blade is prone to wear due to continuous extrusion contact between the blade and the raw material, and provides a raw material granulator for PE granule processing.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a raw material granulator for PE granule processing, comprising a machine body, wherein a feed inlet is provided at the upper end of the machine body; a drive motor is provided on one side of the machine body, and the output end of the drive motor extends into the machine body to provide a screw conveying mechanism; further comprising:

[0006] A rotary cutting assembly includes an outer protective box connected to the machine body. An extrusion tube is located on the side of the machine body near the outer protective box, extending into the outer protective box. A temperature-assisted structure is provided on the extrusion tube. A rotary cutting plate is located inside the outer protective box and opposite the extrusion tube. The rotary cutting plate has a through groove corresponding to the extrusion tube. A motor is located on the back of the rotary cutting plate, and a turntable extends from the motor output end to the front of the rotary cutting plate. Symmetrical cutters are located on the outer side of the turntable.

[0007] A blade cleaning assembly includes cleaning boxes symmetrically arranged on the front of the rotary cutting plate and on both sides of the turntable, with sharpening blades elastically arranged on both sides inside the cleaning boxes;

[0008] A collection assembly includes a collection box disposed below an outer protective box, the inner bottom surface of which slopes downward from one end near the outer protective box to the other end.

[0009] Furthermore, a base plate is provided together with the outer protective box and the lower part of the body.

[0010] Furthermore, the temperature auxiliary structure includes a refrigerant circulation mechanism provided on the outer casing, the refrigerant circulation mechanism being connected to a circulation pipe, the circulation pipe being coiled in the inner wall of the extrusion pipe.

[0011] Furthermore, the inner wall of the extrusion tube is provided with a heat insulation layer.

[0012] Furthermore, the cross-section of each cleaning box is U-shaped.

[0013] Furthermore, all the grinding blades are arc-shaped with convex surfaces facing each other; each grinding blade has several limiting blocks at its upper and lower ends, and each side of the cleaning box has limiting grooves that can slide and connect with the limiting blocks; both the limiting blocks and the limiting grooves are dovetail-shaped.

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] The cleaning box and the internal grinding blades enable continuous cleaning and friction of the blades during the rotary cutting process, making the blades less prone to dulling and wear, and less prone to sticking and accumulating debris.

[0016] The extrusion tube is equipped with a refrigerant circulation pipe, which reduces the fluidity and increases the brittleness of the raw material when it reaches the extrusion tube, making it easier to perform rotary cutting and reducing debris contamination. Attached Figure Description
