Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic filament production, in particular to a granulating device of plastic filament production line. BACKGROUND

[0002] The plastic filament is usually in the form of continuous strips after melting and extrusion, which not only occupies a large space during storage and transportation, but also is inconvenient to manage and transport. By cutting the plastic filament into granules through the granulating device, the volume can be greatly reduced, and the convenience of storage and transportation is improved. In the subsequent processing process, such as injection molding and extrusion molding, the granular plastic raw material is easier to be processed and metered by the processing equipment.

[0003] Most of the current granulating devices do not have cleaning function. When the device cuts the plastic filament, plastic powder will be generated, which will mix into the cut granules. This not only reduces the purity of the granules, but also increases the friction and wear of the device due to the accumulation of powder inside the device, which leads to an increase in equipment failure rate. This not only increases the maintenance cost, but also may affect the continuity and stability of the production line. In addition, with the use of the granulating device, the cutting precision will decrease due to the gradual wear of the cutting tool and other key components, resulting in size errors. When the produced granules do not meet the specified size, the substandard granules will be mixed with the previous standard granules due to the lack of screening function in the device itself, and the staff needs to screen them, which increases the workload of the staff.
