[0058] When packing the slender bricks, four packs are arranged in a column, and there are four columns in total for packing, that is, 16 packs of slender bricks are packed in each box in the 4×4 arrangement. The slender bricks arranged in the thickness direction enter the packing machine through the conveyor belt 3. When the slender bricks simultaneously trigger the sixth photoelectric switch 57, the fifth photoelectric switch 25 and the fourth photoelectric switch 26, it indicates that there are four packs of slender bricks within the moving range of the grouping push plate 24. The piston rods of the two sub-packing cylinders 27 extend to clamp the fifth pack of slender bricks at the rear end of the conveyor belt 3. The grouping cylinder 21 drives the grouping push plate 24 to push the four packs of slender bricks to the right.

[0059] The piston rods of the two sub-packing cylinders 27 retract, and the slender bricks continue to intermittently enter the moving range of the grouping push plate 24 in the state of four packs in a column. When the piston of the grouping cylinder 21 triggers the grouping right detection magnetic switch 23 at the right end, the grouping cylinder 21 is reversely ventilated. The grouping cylinder 21 drives the grouping push plate 24 to move leftward. At the same time, the piston of the left baffle cylinder 33 moves to the right. When the piston of the left baffle cylinder 33 triggers the left baffle in-place detection magnetic switch 34, the air chambers at both ends of the left baffle cylinder 33 are cut off from the air supply, and the left baffle cylinder 33 is in the air pressure state. The grouping push plate 24 pushes the four packs of slender bricks newly conveyed to the rear end of the conveyor belt 3 to the left. The left baffle plate 39 moves to the left with the slender bricks to play a role in blocking the material.

[0060] Repeat this process. When there are four columns of slender bricks in the left grouping area, the piston of the left baffle cylinder 33 moves to the left to trigger the left grouping completion detection magnetic switch 35. The piston rod of the left packing cylinder 41 extends to drive the left packing push plate 52 to push the 16 packs of slender bricks that have completed grouping from the left guiding port to the packing table. When there are four columns of slender bricks in the right grouping area, the piston of the right baffle cylinder 28 moves to the right to trigger the right grouping completion detection magnetic switch 30. The piston rod of the right packing cylinder 48 extends to drive the right packing push plate 53 to push the 16 packs of slender bricks that have completed grouping from the right guiding port to the packing table. After the piston of the left packing cylinder 41 triggers the left packing in-place detection magnetic switch 40, the piston rod retracts and waits for the next action. After the piston of the right packing cylinder 48 triggers the right packing in-place detection magnetic switch 49, the piston rod retracts and waits for the next action.
