Specific working principle

When the feeding hopper 1 is used for feeding, the feeding hopper 1 and the mounting seat 2 should be located above the first discharging hole 401, the lower part of the sleeve 3 extends downwards and stretches into the first discharging hole 401, the mounting seat 2 discharges plastic particles in the feeding hopper 1 downwards, and at this time, the plastic particles enter the material pipe through the mounting seat 2, the sleeve 3 and the first discharging hole 401.

When the injection molding machine needs to change materials for production, the first power source drives the feed hopper 1 to move from the first discharging opening 401 to the second discharging opening 403 along the sliding rail 4. In the process that the sleeve 3 moves along with the feeding hopper 1, the sleeve 3 is contracted upwards because the first inclined plane 301 and the second inclined plane 4011 are propped against each other, the contracted sleeve 3 and the discharging hole move to the second discharging hole 403 along with the feeding hopper 1 through the feeding chute 402, at this time, because the lower part of the sleeve 3 and the discharging hole are positioned in the feeding chute 402 in the whole course, plastic particles falling from the feeding hopper 1 and the mounting seat 2 enter the feeding chute 402, and because the sliding rail 4 and the feeding chute 402 are in an inclined state with one high end and the other low end, the plastic particles slide along the feeding chute 402 under the action of gravity, and finally are discharged from the second discharging hole 403; when the plastic particles slide down to the second discharge opening 403, the blocking piece 4031 can block the plastic particles from scattering outwards, and guide the plastic particles into the second discharge opening 403, so that the plastic particles can be smoothly discharged through the second discharge opening 403.

When the feeding hopper 1 moves to the position above the second discharging hole 403, the lower part of the sleeve 3 stretches into the second discharging hole 403 under the action of gravity so as to discharge plastic particles, and the plastic particles fall from the feeding hopper through the second discharging hole under the action of gravity in the process, at this time, the sleeve 3 can prevent the plastic particles from falling outwards, and meanwhile, the falling plastic particles can be guided, so that smooth progress of the material changing work is ensured. After the material is changed, the second power source pushes the push plate 4032 towards the direction of the feeding chute 402, and at this time, the third inclined surface 40321 abuts against the first inclined surface 301 and forces the sleeve 3 to shrink upwards, so that the sleeve 3 moves along with the feeding hopper 1 towards the direction of the first discharging hole 401.
