Abstract

The invention discloses a feeding bushing fixing device of an extruder. The feeding bushing fixing device of the extruder comprises a cylindrical bushing sleeve, wherein an adjustment thread is arranged inside the bushing sleeve; three adjustment stretching arms are uniformly arranged on the side wall of the bushing sleeve; a strip-shaped through long positioning hole is formed in each adjustment stretching arm; an inclined clamping slope is arranged on each adjustment stretching arm; the inclination angle of each clamping slope is adaptive to the taper of a feeding bushing of the extruder. According to the feeding bushing fixing device of the extruder, the clamping slopes on the adjustment stretching arms are directly meshed with a tapered opening of the feeding bushing; meanwhile, the positions of the long positioning holes are adjusted according to the size and direction of a fit clearance; locking is carried out by using locking through holes finally; the feeding bushing fixing device of the extruder has the advantages of convenience in adjustment, precision, reliability, simple structure and high practicality, and the problem of glue leakage is thoroughly solved.

Description

technical field [0001] The present invention relates to an extrusion device, more precisely, a feed bushing fixture for an extruder. Background technique [0002] The extruder is a common plastic processing equipment. The working mechanism is to rely on the pressure and shear force generated by the rotation of the screw, so that the material can be fully plasticized and evenly mixed, and then formed through the die. The feeding bush of the existing extruder is due to machining (the positioning keyway and the matching part are not on the same axis), resulting in a fit gap between it and the side plate. lead to glue leakage. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing a feeding bush fixing device for an extruder. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] A feeding bushing fixing device for an extruder, t...
