Through setting up transmission cloth area 700, and through the assembly integration of transmission cloth area 700 with mixer 400, block forming machine 600, and combine cloth car 110's arrangement, realized the production connection relation between mixer 400 and the block forming machine 600, make things convenient for the conveying of mix, improve degree of automation.

As a preferred embodiment, the pressing head 602 is arranged on the adjacent side of the blanking hopper 310, the top of the pressing head 602 is connected with an upper oil cylinder 605, the upper end of the upper oil cylinder 605 is fixedly connected with a cross rod 607, two ends of the cross rod 607 are movably connected with the frame 410, and the pressing head 602 moves up and down in the vertical direction under the driving of the upper oil cylinder 605, so that the pressing head 602 is driven by the upper oil cylinder 605 to apply pressure to the surface of the mixture downwards, and the compaction effect of the mixture is improved.

The supporting plate 210 for supporting the formed green bricks can be arranged between the die 601 and the vibrating table 603, the lower part of the vibrating table 603 is provided with a vibration exciter 604, the vibration exciter 604 mainly comprises at least one pair of same rotating shafts, the pair of rotating shafts are provided with the same eccentric block, constant eccentric force or exciting force is generated through the eccentric block, and the exciting force generated by the eccentric block can be decomposed into force in the horizontal direction and force in the vertical direction.

The exciting forces in the horizontal direction can be mutually offset, and the forces in the vertical direction are mutually superposed to form vertical directional vibration so as to generate vibration in the vertical direction; the vibration exciter 604 is connected with a vibration exciting motor 608, the vibration exciting motor 608 drives the vibration exciter 604, the vertical directional vibration of the die 601 and the vibrating table 603 generates resonance under the control of the vibration exciter 604, the mutual friction force in the mixture can be effectively reduced, and the mixture is vibrated and compacted under the combined action of the pressure of the upper pressure head 602, so that the brick blank in the die 601 is quickly, uniformly and compactly molded.

The vibration table 603 is arranged below the mold 601, the two sides of the frame 410 are provided with lower oil cylinders 606, the lower oil cylinders 606 on the two sides are arranged corresponding to the two sides of the mold 601, the inner side of the lower oil cylinder 606 extends towards the mold 601 to form a convex part 510 connected with the side edge of the mold 601, and the convex part 510 supports the side edge of the mold 601; when the green brick is pressed, the lower oil cylinder 606 moves upwards to support the mold 601, so that the green brick is separated from the mold 601 and the mold is released. Through the improved design and assembly of all parts of the block forming machine 600, the conveying and compression forming efficiency of the mixture is effectively improved, and the brick making quality effect is ensured.

In a preferred embodiment, the conveying rack 800 includes an active conveying area and a passive conveying area, the pallets 210 are conveyed from the active conveying area to the passive conveying area, specifically, the active conveying area is responsible for conveying bricks, a travel switch for triggering the stacker 900 to be started is arranged at the end of the passive conveying area, when the next pallet 210 is conveyed to the passive conveying area, the previous pallet 210 is pushed to advance until the travel switch is triggered, and the stacker 900 is started by itself, so as to achieve the purpose of automatically stacking the green bricks by the stacker 900.

A lifter which stacks the supporting plate 210 and the green bricks on the plate stacking machine 900 is arranged in the stacking area, the lifter drives at least two green bricks to rise to a set height, and after a travel switch is triggered, the plate stacking machine 900 moves forwards to the stacking area along the sliding rails; because the supporting plate 210 is sent to the lower part of the mold 601 through the plate feeding machine before the mixture is arranged, after the mixture is pressed into green bricks, the conveying frame 800 drives the supporting plate 210 to convey the green bricks to the plate stacking machine 900, and the lifter descends to stack the supporting plate 210 and the green bricks on the plate stacking machine 900 to a plurality of layers.
