Kneading groove in kneading machine

Abstract

The invention discloses a kneading groove in a kneading machine for improving shearing force to materials, which comprises a groove wall and a groove bottom, wherein the inner surface of the groove bottom is provided with a plurality of bosses, and a plurality of veins are arranged on the surface of each boss. The inner surface of the groove bottom of the kneading groove is provided with the plurality of bosses to increase the shearing force to the materials so as to achieve the aims of shortening the kneading time of silicone rubber and improving the kneading efficiency of the silicone rubber. In addition, the veins arranged on the surface of each boss can further increase the shearing force to the materials in the process of stirring so as to further shorten the kneading time of the silicone rubber, improve the kneading effect on the silicone rubber, and reduce about 5 percent of the energy consumption.

Description

technical field [0001] The present invention relates to a kneader, in particular to a kneading tank in a kneader. Background technique [0002] As we all know, a kneader usually includes: a kneading tank, a pair of stirring shafts arranged in the kneading tank, and a motor and a reducer for driving the stirring shaft. The kneading tank includes: a tank wall and a tank bottom, a tank The inner surfaces of the walls and the bottom of the tank are very smooth. When in use, put various materials that need to be kneaded in the kneading tank, and the shear force between the stirring shaft and the stirring shaft, and between the stirring shaft and the kneading tank formed by the stirring of the mixed material on the stirring shaft (rotor) Under the action of the mixture, the mixed materials can achieve the purpose of melting, gelling and kneading. However, in the process of kneading silicone rubber resin powder and other various additives in this kind of kneader, due to the speci...

Problems solved by technology

However, in the process of kneading silicone rubber resin powder and other various additives in this kind of kneader, due to the special toughness of silicone rubber (the toughness is much greater than other rubber materials), under the same conditions, a batch of other rubber materials is 8 Kneading can be completed in ~10 minutes, and the kneading time of silicone rubber is much longer; this makes the kneading efficiency of silicone rubber relatively low; if you want to shorten the kneading time of silicone rubber and improve its kneading effect, It is necessary to increase the shear force on the material during the mixing process.
