Embodiment 1

[0053] see figure 1 , 2 The concrete hollow slab extrusion device shown includes an extrusion bin 1, a mold core 2, a push plate device 3, a moving feeder device 4, a knife holder rod 5, a compression molding device 7, a wire cutting device 9, a frame 10, Hopper 11, feed bin 12, shielding plate 13.

[0054] The extrusion chamber 1 is a cuboid surrounded by four extrusion chamber plates 101 , the left end is an inlet 106 , and the right end is an outlet 107 . On the inner walls of the two opposing extruded bins 101, a side convex formwork 102 and a side concave formwork 103 are arranged. The side convex template 102 is provided with two parallel protrusions 104 extending to the exit of the extrusion bin, and the side concave template 103 is provided with two parallel concave portions 105 extending to the exit of the extrusion bin. The raised portion 104 is a corresponding tongue and groove structure.

[0055] The compression molding device 7 includes a compression molding l...

Embodiment 2

[0079] Embodiment 2 is different from Embodiment 1 in that: the mold core is different, and the connection structure between the mold core and the knife holder rod is different. Specific instructions are given below.

[0080] In Embodiment 2, the right ends of the eight knife rest bars 5 are respectively connected to the left ends of the upper and lower three connecting plates 14, and there are 33 mold cores 8 (the mold cores on both sides of the middle horizontal plane are half mold cores, the One half of the mold core is connected with another horizontally adjacent mold core. Two half mold cores can be counted as a complete mold core), distributed on three horizontal planes, and two adjacent mold cores located on one horizontal plane The distance between the mold cores is equal, and the mold cores at different levels are staggered up and down. From the left end to the right end, the outer circumference of the cross-section of the mold core 8 gradually increases within the s...

Abstract

The invention provides an extrusion device for concrete core slabs, which can continuously prepare concrete core slabs and is high in production efficiency. The extrusion device comprises a machine frame, a linear cutting device and an extrusion bin with a feed port; a feed port cover plate is connected with a feed port cover plate driving device; one end of each mould core in the extrusion bin is connected with a tool holder bar on the machine frame; the circumferences of the mould cores gradually increase, then maintain unchanged and finally gradually diminish from one end to the other end; a push plate arranged on the tool holder bar in a sliding manner is connected with a push plate pushing device; the total of the maximum cross section areas of all the mould cores is x, the total of the one-end areas of the mould cores is y, the total of the other-end areas of the mould cores is z, and the cross section area of the extrusion bin is w, 3.5(w-x)>=w-y>=2.5(w-x),w-x>w-z>w-y; a discharge port of a storage bin is communicated with the feed port; the feed port cover plate penetrates the storage bin during movement, and the circumference of the feed port cover plate is matched with the inner wall of the storage bin; when a mobile skip car device moves to different positions, the outlet of a stirring bin is communicated with the inlet of the storage bin or sealed by a baffle plate; and a convex part and a concave part are formed on the inner wall of the extrusion bin.

Description

technical field [0001] The technology relates to a preparation device for concrete hollow slabs, in particular to a continuous preparation device for concrete hollow slabs. Background technique [0002] Present concrete hollow slabs all adopt formwork, are prepared by manual method, and production efficiency is low, wastes manpower. Contents of the invention [0003] The purpose of this technology is to provide a concrete hollow slab extrusion device capable of continuously preparing concrete hollow slabs and having high production efficiency. [0004] The concrete hollow slab extrusion device includes a frame, and one end fixed on the frame is an extrusion bin whose inlet is the other end is an outlet; Cover plate; the feed port cover plate is connected with the feed port cover drive device set on the frame to drive the feed port cover plate to move; multiple mold cores are arranged in the extrusion chamber, and one end of the mold core is connected to the extrusion mach...
