Upper-pressing-lower-sucking-type slurry injection structure of automatic plate production line

Abstract

The invention relates to the technical field of foam plate slurry injection, in particular to an upper-pressing-lower-sucking-type slurry injection structure of an automatic plate production line. Theupper-pressing-lower-sucking-type slurry injection structure comprises a material injection device and a vacuum sucking device; the vacuum sucking device comprises a vacuum plate and a vacuum suckingpipe which is connected to the vacuum plate; baffle plates which are hermetically connected with the vacuum plate are arranged on the vacuum plate; the vacuum plate and the baffle plates jointly forma material injection pool of which the opening is upward; the material injection device communicates with the material injection pool; and a downwards-pressing component is hermetically arranged on the inner walls of the baffle plates. By adopting the upper-pressing-lower-sucking-type slurry injection structure of the automatic plate production line, the amount of slurry absorbed in various partsof a plate is consistent; and the speed and efficiency of slurry injection are improved; the slurry can uniformly permeate the whole plate, so that the problem of descending of the yield and fireproof performance of foam plates is avoided.

Description

technical field [0001] The invention relates to the technical field of foam board grouting, in particular to an up-press-down-suction grouting structure in an automatic board production line. Background technique [0002] EPS board (expandable polystyrene board) is a foam board with closed-cell structure formed by foaming and molding. It has the advantages of light weight, low price, low thermal conductivity, low water absorption, and good insulation performance, so it is widely used in construction, communication, vehicles and other fields. [0003] In the field of construction, due to its good thermal insulation performance, EPS boards are mainly placed on the outside of the exterior wall as a thermal insulation wall. At the same time, in order to enhance its fireproof performance, it is also necessary to pour inorganic salt fireproof slurry into the formed board, so that the inorganic salt fireproof slurry can penetrate into the inside of the board to wrap and cover the ...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a solution to solve the problems in the prior art that the amount of slurry sucked in various parts of the foam board is inconsistent and it is difficult to make the slurry completely penetrate into the thicker foam board, thereby affecting the yield and fireproof performance of the board. This kind of plate automatic production line has an up-and-down suction grouting structure, which can keep the amount of slurry sucked in all parts of the plate consistent and improve the rate and efficiency of grouting. It can also make the slurry penetrate the entire plate evenly and avoid the finished product of the foam plate. Rate and fire performance reduction and other issues
