Novel kneading machine propeller shaft and manufacturing method thereof

Abstract

The invention discloses a novel kneading machine propeller shaft which comprises a propeller shaft body. The propeller shaft body comprises a propeller body, a first mounting end shaft and a second mounting end shaft are arranged at the left end and the right end of the propeller body respectively, a shearing groove is formed in the edge of the propeller body, and the center line of the first mounting end shaft and the center line of the second mounting end shaft are located on the same straight line. The specifications of sealing blocking parts and bearing blocking parts of the first mounting end shaft and the second mounting end shaft are the same. The propeller body is of a structure in centrosymmetric about the center line of the propeller body. The front face arc of the propeller in the novel kneading machine propeller shaft is tangent, so that shearing is convenient; and the back concave arc is tangent, so that feeding is convenient. During reverse rotation, paddles do not extrude materials, and conveying of the materials provides favorable conditions for subsequent material drying. The shearing groove is formed in the outer edge of the propeller body, shearing of the materials during longitudinal motion is promoted, the shearing time of the materials is shortened, and meanwhile the load of a motor during material shearing is reduced.

Description

technical field [0001] The invention relates to the technical field of kneader paddle shaft processing, in particular to a novel kneader paddle shaft and a manufacturing method thereof. Background technique [0002] 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 a special mixing and stirring device with two Σ paddles. The fast paddle usually rotates at 42 rpm, and the slow paddle usually rotates at 28 rpm. Different paddle speeds make the kneaded materials quickly Mix well. The paddle shaft of the kneader is an important part of the kneader. Traditional products do not take into account the looseness of the material, and the material sticks seriously. The change to the paddle shaft will make the use of the kneader more convenient and bett...
