Pressing molding machine for hollow bricks

Abstract

The invention relates to a pressing molding machine for hollow bricks. The pressing molding machine comprises a combined supporting frame. A left supporting support is arranged on the left side of the upper end face of the combined supporting frame. A brick conveyor is arranged on the left supporting support. A motor is further arranged on the left portion of the upper end face of the combined supporting frame. A shaft of the motor is sleeved with a drive gear. A brick supporting hydraulic cylinder is arranged on the upper end face of the combined supporting frame. A brick supporting plate is arranged on the brick supporting hydraulic cylinder. A right supporting support is arranged on the right side of the brick supporting hydraulic cylinder. A vertical rod is arranged in the middle of the combined supporting frame. A bearing plate is arranged in the middle of the vertical rod. A brick outlet is formed in the left portion of the bearing plate. Two sliding rails which are parallel in a front-and-back manner are arranged on the top of the vertical rod. A material removing plate is arranged at the right ends of the sliding rails. A brick pressing device is arranged on the sliding rails. A die pushing device is arranged on the upper right side of the combined supporting frame. According to the pressing molding machine for the hollow bricks, the manner that a hydraulic cylinder is used for directly pressing brick molding raw materials in the prior art is changed, instability of the forming quality and the forming size of the bricks is lowered, and the requirement for operation accuracy of the hydraulic cylinder of the pressing molding machine is lowered.

Description

technical field [0001] The invention relates to the technical field of building material processing equipment, in particular to a hollow brick pressing machine. Background technique [0002] With the development of society, the country implements the wall reform policy to achieve the purpose of protecting land and saving energy. In recent years, more and more types of new wall materials have appeared in the society, among which there are more applications, such as gypsum or cement lightweight partition boards, color steel plates, aerated concrete blocks, steel wire grid foam boards, small Concrete hollow blocks, gypsum boards, gypsum blocks, ceramsite blocks, sintered porous bricks, shale bricks, solid concrete bricks, PC slabs, horizontal hole concrete wall panels, activated carbon walls, new partition wall panels, etc. The new wall material is a new type of wall material that is different from traditional wall materials such as bricks, limestone, etc. It has the character...

AI Technical Summary

Problems solved by technology

[0003] With the development of new wall materials, the equipment for manufacturing new wall materials has developed rapidly, and the equipment for manufacturing new wall materials is also diverse, but in general, the method of direct pressing with hydraulic cylinders is the main method. The method has high requirements for the operation accuracy of the hydraulic cylinder. If the extension of the hydraulic cylinder is too large, that is, the pressure of the hydraulic cylinder is too large, it is easy to cause the volume of the brick to be smaller than the average level, resulting in the brick not meeting the size requirements when it is used. On the contrary, the molding material of the bricks cannot be effectively compressed, resulting in low connection strength of the bricks, easy loosening, and large size, etc.
