Device for overlapping broken strip of plastic extruder

Abstract

The invention relates to a device for overlapping when a plastic extruder has a broken strip. The device for overlapping the broken strip of the plastic extruder comprises a plastic extruder head (8) and a cooling water groove (3) positioned in the lower part of the extruder head (8); one side of a strip bracket (5) traversing two sides of the cooling water groove (3) is provided with a vertical cylinder (2); the end part of a push rod of the vertical cylinder (2) is connected with a horizontal cylinder (1); the direction of a push rod of the horizontal cylinder (1) is consistent with the length direction of the strip bracket (5); and the end tip of the push rod of the horizontal cylinder (1) is provided with a rotary baculiform scraper (6) which is driven by a minitype motor (7). The device has a simple and reliable structure, avoids the scalding accident generated by manual overlapping and overcomes the disadvantages that in the prior art, a metal strip is inadvertently dipped on a strip material during overlapping and damages subsequent machines and equipment, thereby ensuring that a plastic granular product is not intermixed with metal chipping.

Description

(1) Technical field [0001] The invention relates to an auxiliary device of a plastic extruder, in particular to a strip-attaching device when the plastic extruder is broken. (2) Background technology [0002] The plastic extruder is commonly used in the production and processing of modified plastics. Various raw materials are fully mixed through the high mixer and added to the ring extrusion machine from the hopper of the extruder. The raw materials are heated and melted in the barrel of the extruder at the same time. Pushed forward by the twin-screw screw, through the extrusion hole at the head of the extruder, plastic strips are discharged. The plastic strips enter the long rectangular water tank to cool and harden. After being cut by the next pelletizer, the plastic strips are processed. into plastic particles. [0003] When the plastic strips are extruded from the extrusion hole of the extruder, due to the uneven mixing in the mixing stage, the powder and particles cann...

AI Technical Summary

Problems solved by technology

Due to the high temperature of the strips that have just been exported, the operator often has scalds when picking up the broken strips by hand. Sometimes the operator uses iron wire or welding rods to build the strips, and pays little attention to the metal parts being stripped. Going to the follow-up granulator, the moving and fixed knives may be damaged, and the shavings of welding electrodes are often found in the cut granules.
