Description

The broken external plastic granulator of film

Technical field

It the utility model is related to a kind of plastics machinery, and in particular to a kind of plastics granulator.

Background technology

Plastic granulator is a kind of equipment that plastic raw materials are made to plastic pellet.It is substantially currently on the market using electricity Heat extrusion way and carry out plastic granulating, is i.e. plastic raw materials are added in horizontal barrel, and barrel passes through the high-power electrical heating in surface Plastic raw materials are subjected to high temperature melt, feeding is then carried out from one long in barrel screw rod and will melt plastics from die head toward It is outer to be extruded into slice, plastic pellet is then cut into by blade after slice water cooling, above-mentioned comminutor energy consumption is big, volume is big. For overcome the deficiencies in the prior art, applicant develops new plastic granulator, is rotated, made using the scraper plate in extrusion die cylinder Scraper block on scraper plate, which rolls the material positioned at extrusion die cylinder inner wall and produces heat, melts material to carry out plastic granulating, no Use electrical heating, thus can have more than 30% it is energy saving.But for the very strong plastic raw materials of some viscosity, the viscosity after thawing Height, mobility are very poor, and enter the plastic raw materials of extrusion die cylinder after the feeding for passing through feeding spiro rod（Generally demihull shape）, its Intermediate gaps are still very big, and the density of raw material is small, therefore also small to the motive force of front material in extrusion die cylinder, extrusion die cylinder Interior pressure is inadequate.So under the effect of above-mentioned composite factor, it may result in when material is extruded from the extrusion cavities of extrusion die cylinder and deposit In difficulty, low production efficiency, and often in the case of material overheat generation coking phenomenon under the rolling of scraper block, cause plastics Granulator cannot be produced normally.

The content of the invention

In view of the deficiencies of the prior art, the purpose of this utility model is to be to provide outside one kind to connect film crushing equipment, and Plastics granulation is carried out in a manner of the material of turning a millstone for increasing density of material, suitable for the external plastic system of broken film of sticky strong plastic material Grain machine.
