An anti-clogging plastic granulator discharge device

Abstract

The invention discloses an anti-clogging discharging device of a plastic granulator. The anti-clogging discharging device comprises a rack, a cylinder and a granulating forming device; the cylinder isarranged on the upper end surface of the rack; a guiding rod is arranged inside the cylinder; a guiding piece is arranged on the outer wall of the guiding rod; an extruding pipeline is arranged on the outer wall of the lower part of the left side of the cylinder; the granulating forming device is arranged at the lower end of the extruding pipeline and comprises a forming template and a supportingplate; and a cooling plate is closely attached to the outer wall of the forming template and the outer wall of the supporting plate. According to the anti-clogging discharging device, a spirally-winding heat conducting pipe is arranged on the outer wall of the extruding pipeline and is connected with an air heater, so that heating and heat preservation can be performed on the inside of the extruding pipeline, and clogging caused by cooling and hardening of molten plastic can be prevented; multiple forming holes are evenly formed in the forming template, the molten plastic enters the forming hole in the forming template along the lower end of the extruding pipeline, and the outer wall of the forming template makes contact with the cooling plate, so that the molten plastic is cooled and formed quickly, and plastic granules are consistent in size.

Description

technical field [0001] The invention relates to the technical field of plastic granulators, in particular to an anti-clogging discharge device for plastic granulators. Background technique [0002] In the plastic manufacturing industry, plastics in various forms are prepared into uniform granules that are convenient for subsequent processing through processes such as melting, extrusion, and pelletizing by plastic granulators. The plastic granulator is mainly composed of screw, barrel, heating system, cooling system and pelletizing system. The plastic is melted under the barrel and heating system, and the strip is formed from the exit of the machine head. The strip is cooled by the cooling system and then enters the cutting machine. The granulator rolls and cuts into granules, which is convenient for packaging to achieve the purpose of easy operation, but it still has the following disadvantages in actual use: [0003] 1. The exit of the existing plastic granulator extruding...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing plastic granulator does not have a thermal insulation device at the outlet where the molten plastic is extruded from the barrel, which can easily cause the molten plastic to cool and harden to cause blockage;

[0004] 2. The size of the granulation depends on the conveying speed of the rolling feed wheel and the cutting rate of the rolling blade on the granulator, which may easily cause inconsistent sizes of plastic particles and rough cutting surfaces;

[0005] 3. The strip is cooled by the cooling fan, the cooling effect is general, it is easy to make the plastic strip cannot be cooled quickly and completely, resulting in deformation and affecting the processing quality
