Problems solved by technology

[0003] However, the traditional polyethylene hot-cutting granulation device adopts the circular cutting method in the process of cutting the material, and the rotation time of the blade is different, resulting in different lengths of the cut material, uneven granulation, and polyethylene Long cooling time or insufficient cooling, resulting in too long granulation time or polyethylene sticking knife

Embodiment Construction

[0026] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0027] Such as figure 1 , figure 2 and image 3 Shown, a kind of polyethylene granulation method of the present invention, this method comprises the following steps:

[0028] S1, put the material into the granulation equipment for granulation;

[0029] S2, a cooling nozzle is installed at the outlet of the granulation equipment in S1, and the cooling nozzle is used to spray cold air to quickly cool the extruded strip polyethylene to improve the brittleness of the polyethylene, and then the cutter is used for cooling The final strip of polyethylene is cut to form polyethylene particles;

[0030] The granulation equipment used in this method includes a loading mechanism 1, a driving mechanism 2, a pressing mechanism 3, a reset mechanism 4, a st...

Abstract

The invention relates to the field of plastic processing, in particular to a polyethylene granulating method. The method comprises the following steps that S1, a material is placed in granulating equipment for granulating; and S2, a cooling spray head is mounted on a discharging opening of the granulating equipment in S1 and is used for spraying cold air to fast cool extruded-out strip polyethylene, the brittleness of the polyethylene is improved, and then the cooled strip polyethylene is cut off by a cutting knife to form polyethylene granules. According to the method, the cold air is adoptedfor fast cooling the polyethylene on the discharging opening, the polyethylene can be cooled fast, and therefore the polyethylene cooling speed is increased, and fast cutting and granulating are facilitated.

Description

technical field [0001] The invention relates to the field of plastic processing, in particular to a polyethylene granulation method. Background technique [0002] Polyethylene is referred to as PE, and polyethylene (PE) is one of the five major synthetic resins. Polyethylene is mainly divided into three categories: linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE), and high-density polyethylene (HDPE). [0003] However, the traditional polyethylene hot-cutting granulation device adopts the circular cutting method in the process of cutting the material, and the rotation time of the blade is different, resulting in different lengths of the cut material, uneven granulation, and polyethylene The cooling time is long or insufficient cooling, resulting in too long granulation time or polyethylene sticking to the knife. Contents of the invention [0004] Aiming at the problems in the prior art, the present invention provides a polyethylene granulation met...
