Abstract

The invention discloses a squeeze-type 3D printing concrete extrusion system, which relates to the technical field of 3D printing machinery and equipment; it includes a horizontally arranged extrusion bin, a feed pipe is connected to the top of the middle part of the extrusion bin, and a squeezer is movable in the feed bin. The extruder has an arc groove on one side of the extruder, and the center line of the arc groove coincides with the horizontal center line of the extrusion bin; the two ends of the extruder are respectively fixedly connected with an extruder rod, and the extruder rod The ends far away from the extruder are respectively installed in the fixed tube of the extruder rod, and the ends of the fixed tube of the extruder rod away from the extruder rod are fixedly arranged on the inner walls of both ends of the extruder; The two ends of the conveying pipe of the type structure are connected, and the bottom of the conveying pipe is connected with the discharge pipe; a motor is installed on one side of the extrusion bin, and the output shaft of the motor is connected with a Z-shaped transmission rod, and the end of the Z-shaped transmission rod is slid to set in an arc inside the groove. The invention utilizes the reciprocating motion of the extruder to realize uniform and stable extrusion of printable materials.

Description

technical field [0001] The invention relates to the technical field of 3D printing machinery and equipment, in particular to an extrusion 3D printing concrete extrusion system. Background technique [0002] As a new construction technology, concrete 3D printing technology has become the trend of the times leading technological innovation in the field of construction. Currently, the 3D printer extrusion system uses a screw shaft to extrude concrete materials. The design of the extrusion system largely determines the material discharge method and the performance of the material and structure. Using the extrusion method of the spiral stirring shaft, there are many bubbles and voids inside the material, and it is difficult to effectively solve the problem of printing quality. [0003] The patent with the publication number CN208133209U proposes a concrete 3D printing extrusion head, which mainly includes a motor, a fixed cover, a feeding pipe, a spiral stirring shaft, a nozzle,...
