6cm, third swingle are 3cm, and first swingle, the second swingle and third swingle are the telescopic body of rod, packet
The first telescopic rod, the second telescopic rod and third telescopic rod are included, the third stretches rod set in the second telescopic rod, the second telescopic rod
It covers in the first telescopic rod a.By the setting of the first swingle, the second swingle and third swingle, during rotation,
First telescopic rod, the second telescopic rod and third telescopic rod ceaselessly stretch, significantly more efficient to get through blocked hopper, simultaneously
First swingle is 8cm, and the second swingle is 6cm, and third swingle is 3cm, is that entire anti-blocking swingle seems and thinks one
Taper is more conducive to being downwardly into the inside of blocking plastics.
Preferably, the first swingle, the second swingle and the equal level of third swingle are placed equidistant with.
Preferably, the inner wall lower end of the conical hopper is symmetrically installed there are two hold-down support, on the hold-down support
It is connected with runner by bearing, the runner includes left wheel and right wheel, and the left wheel rotates clockwise, the right wheel
It rotates counterclockwise, the surrounding of the runner has tooth socket.Setting runner is to help macromolecule plastic particle and preferably enters
In injection molding machine, the generation of clogging is effectively prevented.
Preferably, the runner is made of rubber material.
The beneficial effects of the utility model are:
The utility model passes through the setting of telescopic rod and anti-blocking swingle, and when blockage phenomenon, telescopic rod elongation is prevented
Stifled swingle rotation, effective solution clogging, passes through setting for the first telescopic rod, the second telescopic rod and third telescopic rod
It sets, effectively raises the working efficiency of anti-blocking swingle, the setting of runner makes macromolecule plastic particle preferably enter injection molding
In machine, the effective generation for preventing clogging.
