Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of polyethylene wax granulation, and particularly relates to a granulator for polyethylene wax production. BACKGROUND

[0002] Polyethylene wax (PE wax), also known as high molecular wax or polyethylene wax, is an important chemical material. In the production process, the material is plasticized and extruded into a sheet or a strip by an extruder. The extruded polyethylene wax is then cut into granules by a granulator after air cooling or water cooling. Cutting into granules not only ensures the uniformity of the polyethylene wax, but also allows for flexible adjustment according to the needs of different application fields, such as changing the size and shape of the granules. More importantly, granular polyethylene wax is easier to mix uniformly with other additives, thereby improving the overall performance of the product.

[0003] In the existing polyethylene wax cutting process, manual assistance may be required to limit and fix the position of the polyethylene wax to ensure the accuracy and efficiency of the cutting. In the existing polyethylene wax cutting process, manual assistance may be required to continuously push the polyethylene wax to the cutting area. Manual pushing may result in uneven distribution of the polyethylene wax during the pushing process, affecting the uniformity and quality of the cutting.

[0004] For example, the extruder cutting device disclosed in the patent with the publication number CN219153410U is applied to a polyethylene wax production system.

Moreover, it does not have the function of automatically pushing the polyethylene wax to the cutting area, mainly relying on manual operation. However, manual pushing not only requires a lot of time and manpower, but also may cause inconsistencies in manual operation, resulting in differences in cutting size and shape, and affecting the quality of the final product.
