A plastic kneader

Abstract

The invention belongs to the technical field of packaging, and discloses a plastic kneader. The plastic kneader comprises a fixed base; a top cover is arranged on the fixed base; a press plate is hinged to the side wall of the top cover; a driving transmission cylinder is vertically arranged on the fixed base and penetrates through the top cover; the driving transmission cylinder is in flat key connection with the eccentric position of the top cover; an air pump is externally connected with the upper end of the driving transmission cylinder; a penetrating hole is formed in the fixed base; an air flue communicating with the penetrating hole is arranged inside the fixed base and externally connected with the air pump; a driven transmission cylinder is inserted into the penetrating hole; the cylinder body section, on an inner cavity of the top cover, of the driving transmission cylinder is in flat key connection with a driving stirring piece; the upper end of the driven transmission cylinder extends into the inner cavity of the top cover but is not connected with the top cover; and the section, extending into the top cover, of the driven transmission cylinder is connected with a driven stirring piece. The plastic kneader can engage materials at the dead corners and improve the overall kneading effect of the materials.

Description

technical field [0001] The invention belongs to the technical field of plastic processing. Background technique [0002] The plastic kneader is a kind of stirring mixer, which is mainly composed of a mixing chamber and a pair of stirring blades rotating in opposite directions. It is used to mix high and low viscosity plastic substances. It has high mixing efficiency, uniform mixing materials, convenient operation and Easy to clean and other features. A common kneader consists of a cover and an inner cylinder from top to bottom. The inner cavity of the inner cylinder is a mixing chamber. Two mixing knives are arranged side by side in the bottom of the mixing chamber (the speeds of the two mixing knives are different, which can avoid forming a symmetrical Circulation reduces the meshing effect), when working, the two mixing knives rotate in reverse, so that the plastic material turns along the side wall of the mixing chamber, and the plastic material enters the gap between th...

Problems solved by technology

[0003] The disadvantages of the above-mentioned kneading machine are: 1. Only relying on the kneading of the mixing knife makes the material squeezed, but the material in the dead corner of the mixing chamber cannot be kneaded and pressed, which eventually leads to poor plastic kneading effect; 2. The mixing knife The thickness of the mixing chamber is fixed, and the size of the gap in the middle of the mixing chamber is also fixed. It cannot be adjusted according to the amount of material (that is, the amount of kneading). After the pressure, it falls between the two mixing blades, that is to say, the material is not squeezed vertically here, and the final kneading effect is not good; 3. The separated water generated in the mixing chamber will still remain in the mixing chamber before the kneading is completed. Mixing chamber, so that the material will absorb part of the analysis water again, and the water content of the lowest plastic mixing volume is too high
