After mixing, extruding bricks, drying, baking, sintering and other processes, block bricks are made. In order to make the structure of the block bricks denser, a pressing head device is generally used to press the bricks into shape at one time. Now it is necessary to manufacture a double-layer pavement brick that is pressed into shape in two layers by two materials, base material and surface material. In the pressing process, the base material is first arranged in the brick making mold, and the brick making machine pressing head is used for the first pressing, and then Finally, the fabric is arranged on the basis of the base material, and then the brick making machine pressure head is used to perform a second pressing to form double-layer bricks; therefore, a base material feeding cart and a fabric feeding cart are respectively arranged on both sides of the brick making mold, and the brick blanks cannot be directly transported to the outside of the brick making machine in a straight line along the feeding direction, and are generally transported to the outside of the brick making machine from the other two sides of the brick making mold; however, a conveying mechanism perpendicular to the feeding direction needs to be set, and the conveying mechanism needs to be set on the corresponding frame, which not only increases the purchase cost of the brick making equipment, but also the brick making equipment occupies a large area and has low space utilization rate of the factory building.
