Rotor-type raw material supplier

Abstract

The present invention relates to a raw material feeder which measures and supplies fixed quantities of raw materials to various types of plastic molding machines, such as injectors and extruders. The present invention provides a smooth supply of raw material because a cutting knife with a V-shaped groove is placed in the rotor with a measuring cup, and a raw material transfer groove is formed in a portion where material accumulates so that the material on top of the measuring cup is cut and the rest is discharged through an outlet, thereby minimizing load and preventing transfer failure.

Description

technical field [0001] The present invention relates to a raw material supply device that measures a certain amount of raw material and supplies it to a plastic molding machine such as an injection machine or an extruder. Specifically, it relates to a raw material supply device that can measure and supply quickly and accurately, and can measure stably even at the upper end of a vibrating molding machine. It is a rotor-type raw material supply device that is simple in structure, trouble-free, compact in appearance, and can minimize the installation area. Background technique [0002] Usually, when plastic raw materials are molded by extrusion or injection, in order to make the product have the desired color or special function, the raw material supply device not only supplies the main raw material, but also mixes and inputs auxiliary materials according to a certain ratio, that is, the desired color or color. Additives (hereinafter collectively referred to as raw materials) t...

AI Technical Summary

Problems solved by technology

[0005] However, in the raw material supply device with the above structure, there are problems as follows: when the gate valve is opened and closed, the amount of raw materials discharged is not uniform, and the accuracy of measurement cannot be guaranteed, thereby increasing the defective rate of products. In addition, when the gate valve is closed, the raw material Being sandwiched between the gate and the gate, poor closing and failure often occur, and raw material particles are crushed, resulting in defective products

[0010] However, the length of the pair of screw rods is relatively long, the volume of the outer cover around them is large, and the number of various accessories used to drive the pair of screw rods is large, resulting in problems such as large volume and large installation area. There is also the problem that the delivered raw materials cannot be measured correctly, and the supply of raw materials is not accurate enough
