Description

Technical Field

[0001] The utility model relates to the technical field of horizontal kneaders, in particular to a large-angle turning automatic feeding and discharging horizontal kneader. Background Art

[0002] The horizontal kneading machines currently used in the explosives industry are mainly tilting cylinder kneading machines and screw discharge kneading machines. The tilting cylinder kneading machine uses manual feeding, and the discharge uses a side water cylinder to drive the kneading cylinder to flip and unload. Due to the mechanical structure limitation, the flip angle is less than 90 degrees, and the material is not discharged cleanly, requiring manual intervention. The screw discharge kneading machine discharges the material outward by rotating the screw, but this discharge method may cause a small amount of material to be unable to be discharged. Since the material is flammable and explosive, there is a safety hazard. In addition, the above two types of kneading machines cannot be automated.
