Disassembling and assembling equipment for screw of plastic extruder

Abstract

The invention belongs to a plastic production machine, in particular to disassembling and assembling equipment for a screw of a plastic extruder. In the prior art, the disassembly and assembly of the screw of the plastic extruder are performed manually by using a raising bar, and therefore have the drawbacks of damaging the screw and scalding operators. In the equipment, a reducer motor (1) drives gears (2), (3) and (4) and threaded rods (5) and (6); the rotation of threaded rods (5) and (6) drives a fixed clamping block (9) to perform a linear motion; the screw, to be disassembled and assembled, of the extruder is fixed by an internally-threaded hole (10) in the fixed clamping block (9) and a bolt; the linear motion of the fixed clamping block (9) drives the screw of the extruder to perform a linear motion; and thus, the disassembly and assembly of the screw of the plastic extruder are completed. The equipment has the advantages that: the disassembly and the assembly of the screw of the extruder is more quick and the production efficiency is high; the manual operation by using the raising bar is changed into mechanical operation, so the damages to the screw are reduced; the production cost is reduced; the use is safe, and the damages to the equipment and the safety accidents of the operators are reduced.

Description

technical field [0001] The invention relates to a plastic production machine, in particular to a plastic extruder screw disassembly device used in the processing of modified plastics. Background technique [0002] In the processing of modified plastics, a certain batch of products needs to be changed after production. The composition, color and performance of different batches of products are different, which requires the cleaning operation of the plastic extruder. For products with large differences in composition, color and performance, the screw of the extruder needs to be replaced when cleaning the machine. In the prior art, the disassembly and installation of the extruder screw are all done manually with a warping rod to warp the screw rod out and in. This is easy to cause damage to the screw; it is difficult to take out the screw of the plastic extruder for the production of special materials; at the same time, the temperature of the screw just taken out is high, and...

AI Technical Summary

Problems solved by technology

In the prior art, the disassembly and installation of the extruder screw are all done manually with a warping rod to warp the screw out and in.

This is easy to cause damage to the screw; it is difficult to take out the screw of the plastic extruder for the production of special materials; at the same time, the temperature of the screw just taken out is high, and it is easy to be scalded by manual operation; it is also easy to cause damage to the screw when installing the screw manually

[0003] In the practice of plastic production, there is no disassembly and assembly of plastic extruder screw equipment. After searching domestic and foreign patent documents, there are also technical documents on disassembly and assembly of plastic extruder screw equipment.
