Abstract

The invention discloses a feeding system of a food packaging barrel injection molding machine. The feeding system comprises a spiral feeder, and a shell of the spiral feeder is conical; a heater is fixedly wrapped at the tail end of the shell; an inclined baffle which gradually inclines downwards in the feeding direction is formed at the tail end of the shell, and the bottom of the tail end of the shell communicates with an injection molding machine body through an L-shaped feeding pipeline; the inner diameter of the tail end of the shell is larger than that of the L-shaped feeding pipeline; and the middle of the spiral feeder communicates with a negative pressure cavity through a plurality of micropores, and the negative pressure cavity is provided with a first negative pressure pump through a communicating pipe. The feeding system is simple in structure and convenient to use, bubbles wrapped after melting move upwards and overflow through the inclined baffle, a vibrator and the L-shaped feeding pipeline, new gas is prevented from being wrapped when materials move, in addition, the inner diameter of the L-shaped feeding pipeline is small, extrusion is formed, and therefore gas in the L-shaped feeding pipeline is effectively extruded out.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a feeding system for a food packaging barrel injection molding machine. Background technique [0002] When the food packaging barrel is produced by injection molding, it is easy to get air involved when it is fed. This leads to air in the material of the food packaging barrel after injection molding, resulting in low overall structural strength and prone to leaks. Some people set up a negative pressure structure in order to reduce the air bubble content, but because the initially entered material is particles, there are gaps between the particles, so it is easy to wrap the air bubbles when it melts. It is difficult to remove the gas included during melting only by setting a negative pressure structure. Contents of the invention [0003] In order to solve the above technical problems, the present invention proposes a feeding system for a food packaging barrel injection molding machine. ...
