Plastic granulator with film breaking function

Abstract

The invention discloses a plastic granulator with a film breaking function. The plastic granulator comprises a material inlet cylinder, a feeding cylinder and a feeding screw rod, wherein the materialinlet cylinder is connected with the upper portion of the feeding cylinder, and the feeding screw rod is rotationally arranged in the feeding cylinder and driven by a main motor. The plastic granulator is characterized in that a material inlet bin is arranged at the top of the material inlet cylinder, the side wall of the material inlet bin is provided with a discharge hole, a movable knife and afixed knife are arranged in the material inlet bin, the fixed knife is connected with the side wall of the material inlet bin, and the movable knife is connected to a cutter head; and a comb plate isarranged below the material inlet bin, and the cutter head and the comb plate are fixedly connected with the upper rod end of the feeding screw rod. The plastic granulator has the film breaking function, plastic granulation is carried out in a material pushing and grinding mode with the material density increased, and the plastic granulator is suitable for high-viscous plastic materials.

Description

technical field [0001] The invention relates to a plastic machine, in particular to a plastic granulator with the function of breaking film. Background technique [0002] Plastic granulator is a kind of equipment that makes plastic raw materials into plastic particles. At present, the electric heating extrusion method is basically used in the market for plastic granulation, that is, the plastic raw materials are added into the horizontal barrel, and the barrel is heated by high-power electric heating on the surface to melt the plastic raw materials at high temperature. The long screw feeds the material and extrudes the melted plastic from the die to form thin strips, and then the thin strips are cut into plastic particles by the blade after water cooling. The above-mentioned granulator consumes a lot of energy and has a large volume. In order to overcome the deficiencies in the prior art, the applicant has developed a new type of plastic granulator, which uses the rotation ...

AI Technical Summary

Problems solved by technology

However, for some highly viscous plastic raw materials, after melting, the viscosity is high and the fluidity is extremely poor, and the plastic raw materials (generally in the form of flakes) that enter the extrusion mold after being fed by the feeding screw, the gap in the middle is still very large. Large, the density of the raw material is small, so the driving force on the front material in the extrusion die is also small, and the pressure in the extrusion die is not enough

Therefore, under the action of the above comprehensive factors, it will lead to difficulties in extruding the material from the extrusion hole of the extrusion die, and the production efficiency is low, and often the material is overheated under the rolling of the scraper block to cause coking, resulting in The plastic granulator cannot produce normally
