Description

A kneader for uniform mixing

technical field

The utility model relates to the technical field of kneaders, in particular to a kneader with uniform mixing.

Background technique

The kneader is an ideal equipment for kneading, mixing, vulcanization and polymerization of high-viscosity and elastic-plastic materials. The kneader can be used to produce silicone rubber, sealant, hot melt adhesive, food rubber base, pharmaceutical preparations, etc. The kneader is mainly composed of five parts: the kneading part, the base part, the hydraulic system, the transmission system and the electric control system. The hydraulic system uses a hydraulic station to control the oil cylinder to complete the opening and closing functions, and to complete the functions of turning over the cylinder and opening the cover. The kneader is a special mixing and stirring device, which has a pair of rotating paddles that cooperate with each other. The pair of paddles can generate a strong shear force on the plastic, so that the semi-dry state or rubber-like viscous plastic material can react quickly. In order to obtain evenly mixed materials; the two paddles are divided into fast paddles and slow paddles, one paddle is fast and the other is slow, so as to generate shear force, so that the mixed material can be sheared quickly Cutting, so that the materials can be mixed evenly, and different paddle speeds can make the mixed materials be stirred quickly and homogeneously.

However, although the kneader is equipped with two mixing paddles that cooperate with each other, it will be in a highly rotating state when it is working, and it needs to have a certain distance from the bottom, otherwise it is easy to cause damage to the bottom of the kneader, and the stirring paddles have a certain distance from the bottom , it will not be able to stir the materials deposited at the bottom of the kneader. Generally, the materials kneaded by the kneader are generally high-viscosity materials. The combination of the two will eventually cause the materials at the bottom of the kneader to easily stick and agglomerate; some materials are kneaded When kneading and reacting in the kneading machine, harmful gas will be produced, and the existing kneading machine usually discharges it directly into the air, which will not only affect the health of the operators, but also pollute the environment; in addition, the existing Most of the kneading machines in the kneading machine are manually taken out after the kneading is completed, which consumes a lot of manpower and material resources.
