Right-angled double-inlet and one-outlet vacuum forming machine

Abstract

The invention provides a right-angled double-inlet and one-outlet vacuum forming machine. The machine comprises a double-spiral feed box, a vacuum chamber, a spiral receiving box and an extrusion mudcylinder; a double-spiral conveying reamer set is arranged in the double-spiral feed box; a single-spiral extrusion reamer is arranged in the spiral receiving box; the double-spiral conveying reamer set and the single-spiral extrusion reamer are combined to form a double-spiral feeding and single-spiral extrusion mechanism; an outlet of the double-spiral feed box is connected with an inlet of thevacuum chamber; the raw material advancement directions in the double-spiral feed box and in the vacuum chamber are on the same straight line; an outlet of the vacuum chamber is connected with an inlet on the side surface of the spiral receiving box; and the raw material advancement directions in the vacuum chamber and in the spiral receiving box are perpendicular to form a right-angled extrusionreceiving structure. Through use of the double-spiral feeding and single-spiral extrusion mechanism and the right-angled extrusion receiving structure, a mud pressing plate and output power are saved,so that the raw material molecule compactness is improved, the production process flow is shortened, the equipment volume is reduced, the equipment is more compact, the production cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of brick and tile extruders, in particular to a right-angle double-inlet and single-outlet vacuum forming machine. Background technique [0002] At present, the vacuum extruder structure developed by my country's brick and tile equipment manufacturing industry is mainly composed of feed inlet, feed mixing box, mud pressing plate, mud cylinder, vacuum chamber, extrusion reamer, machine head and abrasive tools. The original process of the vacuum extruder in my country is: the loose raw material enters the mixing conveying box with stirring teeth from the feeding port, and is sent into the mud cylinder through the spiral stirring knife, and the mud is pressed by the specially designed power output shaft. The plate prevents the return of raw materials, and through the function of the mud pressing board, it prevents the return of raw materials, so that the raw materials can be fully kneaded, squeezed and kneaded i...

Problems solved by technology

The increase in production efficiency is still not large, and the equipment manufacturing cost, capital investment and energy consumption must be kept at the same pace to achieve a certain purpose. This method brings too much added value, so it is not feasible
