Disassembling and assembling tool for cutter head of dicing cutter for producing resin

Abstract

The invention discloses a disassembling and assembling tool for a cutter head of a dicing cutter for producing resin, and relates to the field of resin production equipment, wherein the disassemblingand assembling tool comprises a disc, wherein the disc is in butt joint with the cutter head of the dicing cutter and can cover the whole cutter head of the dicing cutter; a central hole for conveniently disassembling and assembling a connecting bolt between the cutter head of the dicing cutter and a shaft is formed in the center of the disc; at least three positioning holes matched with mountingholes in the cutter head of the dicing cutter are symmetrically formed in the disc around the center hole by a circle; the positioning holes are through holes; a mounting part is arranged on the outercircumference of the disc, at least three short pipes with internal threads are fixedly arranged on the mounting part and are symmetrically arranged around the circle center, jackscrews are in threaded connection with the interiors of the short pipes, one end of each jackscrew is fixedly connected with a nut, and the other ends of the jackscrews are made into smooth planes; a lifting lug for lifting is arranged at the upper part of the disc. The disassembling and assembling tool has the characteristics that the cutter head of the dicing cutter is convenient to replace, the spline contact surface is prevented from being damaged, and the safety is high.

Description

technical field [0001] The invention relates to the field of resin production equipment, in particular to a tool for disassembling and assembling the cutter head of a granulator used for producing resin. Background technique [0002] The service life of the pelletizer of the EVA / LDPE production plant pelletizer is 3-5 months, which varies according to the index of the product, so the cutterhead of the pelletizer needs to be replaced regularly. Every time the cutter head is replaced, it can only be aligned with the sling and chain hoist, and the cutter head can be pried out with a crowbar; moreover, the connection between the cutter head and the shaft is a spline contact, which requires relatively high precision, and the operation is a little careless It will lead to damage to the spline contact surface, and it will take a lot of time to repair in the later stage, and the cutter of the cutter head is exposed, there is a risk of cuts when the staff disassembles and assembles, ...
