[0026] A using method of a concrete block forming machine for processing includes the following steps:

[0027] Start the second hydraulic rod. The second hydraulic rod stretches, and the lifting plate moves upward. The first gear is inserted into the gear groove. The second motor rotates to drive the second synchronous wheel to rotate, and the second synchronous belt also drives accordingly. The axially distributed first rotating shaft drives the first connecting rod to rotate, and the mold can be switched. After the switching is completed, the telescopic rod of the second hydraulic rod is compressed to the initial state;

[0028] When the square mold needs to be used, the first electric cylinder stretches to drive the first wedge block to move. The first auxiliary wheel rotates along the inclined groove at the bottom of the first wedge block. The first auxiliary wheel drives the first material plate, the second material plate, and the third material plate to move towards the center of the square mold, and the inner diameter of the square mold changes;

[0029] When the circular mold needs to be used, insert the block into the card slot. The first splicing block and the second splicing block with different inner diameters can be spliced into a first fixed block with different inner diameters. Then insert the T-shaped block into the T-shaped groove to assemble a complete circular mold. Hexagonal concrete blocks can also be made in the circular mold. After the hexagonal splicing blocks are spliced, insert them along the T-shaped groove to obtain a hexagonal mold;

[0030] The telescopic rod of the first hydraulic rod is compressed, and the second support plate rotates towards the inner wall of the first support plate. The concrete material falls into the mold from the blanking pipe. The telescopic rod of the first hydraulic rod stretches, and the blanking pipe is blocked by the second support plate. The third motor rotates to drive the disc to rotate. The fixed column is stuck into the groove to drive the rotating block to rotate, and the main rotating shaft also rotates accordingly, driving the turntable to rotate, and the next mold reaches below the blanking pipe;

[0031] When the mold filled with concrete material reaches the discharge port, to make square blocks, directly start the third electric cylinder. The third electric cylinder stretches, and the third fixed block drives the second pressing block to move downward. The second pressing block extrudes the concrete material in the square mold to make it form. When making circular blocks, the fourth electric cylinder stretches, and the second slider moves towards the contact sensor. The third slider stops after touching the contact sensor. The first pressing block is replaced at the center of the third fixed block;

[0032] The rotation of the first motor drives the rotation of the first synchronous pulley, which drives the transmission of the first synchronous belt. The two second bevel gears also rotate accordingly, driving the rotation of the first bevel gear. The two second rotating shafts also rotate accordingly, driving the simultaneous rotation of the four second gears. The four first racks slide out of the third chute and move upward.

[0033] The second hydraulic rod stretches, and the lifting plate moves upward, driving the first rack to move upward. The first rack jacks up the bottoms of the square mold and the circular mold, and the formed concrete blocks in the mold are exposed. The fifth electric cylinder stretches, and the fourth fixed block moves toward the jacked-up square mold and circular mold.

[0034] The rotation of the fourth motor drives the rotation of the conveyor belt. The top of the sliding rod is squeezed by the second connecting rod, and the second auxiliary wheel slides downward along the sixth chute. The pushing plate moves toward the concrete block, and the pushing plate pushes the concrete block toward the discharge port. The concrete block slides from the blanking plate onto the conveyor belt.

[0035] The telescopic rod of the fifth electric cylinder compresses, the sliding rod is not squeezed, the pushing plate and the fourth fixed block return to the initial state, and the first brush and the second brush at the bottoms of the fourth fixed block and the pushing plate also return to the initial state accordingly. The telescopic rod of the second hydraulic rod compresses, the lifting plate moves downward, and the square mold and the circular mold at the discharge port are abutted against the top of the turntable again, and then the next blanking continues.

[0036] The beneficial effects of the present invention: The setting of the block mechanism can enable the rapid forming of concrete materials and improve the production efficiency of blocks. The block mechanism includes a square mold and a circular mold. The stretching of the first electric cylinder drives the movement of the first wedge block, and the first auxiliary wheel drives the first material plate, the second material plate, and the third material plate to move toward the center of the square mold. The inner diameter of the square mold changes, and the first splicing blocks and the second splicing blocks with different inner diameters can be spliced into the first fixed blocks with different inner diameters. Then, the T-shaped block is inserted into the T-shaped groove to assemble a complete circular mold. Hexagonal concrete blocks can also be made in the circular mold. After the hexagonal splicing blocks are spliced, they can be inserted along the T-shaped groove to obtain a hexagonal mold, and concrete blocks of different sizes and shapes can be made, and the operation is simple and flexible.

[0037] The setting of the lifting mechanism can enable the rapid demolding of blocks. The rotation of the first motor drives the four first racks to slide out of the third chute and move upward. The second hydraulic rod stretches, and the lifting plate moves upward, driving the first rack to move upward. The first rack jacks up the bottoms of the square mold and the circular mold, and the formed concrete blocks in the mold are exposed. At the same time, when the lifting plate moves upward, the first gear is inserted into the gear groove. The lifting mechanism can also assist the block mechanism to convert the mold, and the simultaneous conversion of the mold can improve the working efficiency and reduce the labor cost.

[0038] The setting of the pusher mechanism can assist in the blanking of the building blocks. The top of the sliding rod is squeezed by the second connecting rod, and the second auxiliary wheel slides downward along the sixth chute. The push plate moves toward the concrete building block, and the push plate pushes the concrete building block toward the discharge port. The concrete building block slides from the blanking plate to the conveyor belt. Subsequently, the telescopic rod of the fifth electric cylinder contracts, and the fourth fixed block and the first and second brushes at the bottom of the push plate also return to the initial state. During the movement, the excess concrete on the turntable can be cleaned up, ensuring the continuous and efficient operation of the entire building block forming production line.
