Embodiment 1

[0052] see figure 1 , 2 The hollow concrete slab continuous extruder shown includes an extrusion chamber 1, a mold core 2, a push plate device 3, a moving feeder device 4, a knife holder rod 5, a die pressing device 7, a wire cutting device 9, and a frame 10 , Hopper 11, feed bin 12, baffle plate 13.

[0053] 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.

[0054] The compression molding device 7 includes a compression molding...

Embodiment 2

[0078] 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.

[0079] 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 a continuous extruding machine for hollow concrete slabs, which can prepare concrete hollow slabs continuously and has high production efficiency. The continuous extruding machine comprises a rack and an extrusion bin provided with a feed port, wherein a feed port cover plate is connected with a feed port cover plate drive device; one end of each mould core in the extrusion bin is connected with each tool rest rod on the rack through three connecting plates up and down; the circumference of each mould core is increased gradually, maintained changeless, then decreased gradually from one end to the other end; pushing plates glidingly arranged on the tool rest rods are connected with a pushing plate push device; a sum of areas of maximum cross-sections of mold cores is set as x, a sum of areas of one end of each mould core is set as y, a sum of areas of other end of each mold core is set as z, the area of a cross section of the extrusion bin is set as w, and then 3.5(w-x)>=(w-y)>=2.5(w-x), and w-x>w-z>w-y; the other end of each mold core is hexagonal; a discharge port of a storage bin is communicated with a feed port; the feed port cover plate penetrates through the storage bin during movement, and the circumference of the feed port cover plate is matched with the inner wall of the storage bin; and bulged parts and recessed parts 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 hollow concrete slab continuous extruder capable of continuously preparing concrete hollow slabs and having high production efficiency. [0004] The hollow concrete slab continuous extruder includes a frame, which is characterized in that: one end fixed on the frame is an extrusion chamber with an inlet and the other end is an exit; a feeding port is set on the upper wall of the extrusion chamber; A feeding port cover is arranged at the mouth; the feeding port cover is connected with the feeding port cover driving device arranged on the frame to drive the feeding...
