Fig. 2 is a schematic view of the interior of the feed transfer hopper of fig. 1.
Detailed Description
The following describes in further detail specific embodiments of the present invention based on the drawings. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
Referring to fig. 1, the utility model provides an injection molding device automatic feed device installs on an injection molding device, and injection molding device includes hot pressing extruder 100 and sets up the main hopper 200 on hot pressing extruder 100, the utility model provides an injection molding device automatic feed device includes storage unit 10, sets up feeding transfer hopper 20, negative pressure generator 30, the hose 40 on main hopper 200.
The feed transfer hopper 20 is connected to both the stocker unit 10 and the negative pressure generator 30 via a hose 40.
A metal insertion tube 50 is connected to an end of the hose 40 facing the magazine unit 10, and the end of the metal insertion tube 50 has a tip portion so as to extend into the magazine unit 10.
Referring to fig. 2, the feeding transfer hopper 20 includes a hopper housing 21, a filter screen 22 disposed in the hopper housing 21, a feeding port 23 disposed on the hopper housing 21 and below the filter screen 22, an air suction port 24 opened on the hopper housing 21 and above the filter screen 22, a vibration unit 25 disposed above the filter screen 22 and abutting against the filter screen 22, a blowing fan 26 disposed on an inner side of a top wall of the hopper housing 21, and a material sensor 27.
In the present embodiment, a mounting plate is provided on the inner side wall of the hopper case 21 above the screen 22 in a protruding manner, and the vibration unit 25 is mounted on the bottom surface of the mounting plate.
The bottom of the hopper shell 21 is provided with a hopper neck 211, and the materials enter the main hopper 200 through the hopper neck 211 under the action of gravity after entering from the feed inlet 23. The material sensor 27 is mounted in the hopper neck 211.
