[0038] The working principle of the pre-hole stacking, conveying, rotating and packaging integrated machine of the present invention is as follows:

[0039] First, the bricks to be stacked and packaged are placed on the 45° flip-over type synchronous belt conveyor 1. The 45° flip-over type synchronous belt conveyor 1 controls the octagonal flipping, and each time it rotates 45 degrees, it automatically and continuously flips to change the height of the brick placement position. When the bricks move to the conveying outlet end of the 45° flip-over type synchronous belt conveyor 1, the reserved hole stacker 2 works;

[0040] Second, the second servo drive body 262 on the reserved hole stacker 2 is actuated, and the two second drive gears on the second servo drive body 262 rotate clockwise. Through the cooperation of the two second drive gears and the two chains 24, the support frame plate 261 is moved to the left on the door frame 21 through the four rollers 264 on the bottom side, so that the support frame plate 261 drives the longitudinal rod 27 and the brick clamping mechanism 29 to move above the delivery outlet end of the 45° flip-down type synchronous belt conveyor 1, and then the two first drive gears on the first servo drive body 23 are controlled to rotate clockwise, so that under the action of the first servo drive body 23, the two chains 24 are limited by the guide chain frame 25, and the longitudinal rod 27 is moved downward on the inner side of the support frame plate 261 through the cooperation with the first guide chain gear 28, so as to be close to the bricks;

[0041] Third, the first motor 292 can be controlled to rotate the position direction of the two clamping arms 298 as needed. Under the action of the first motor 292, the driving gear 293 drives the driven gear ring 294 to rotate on the surface of the connecting frame 291, and the support frame 295 is indexed through the driven gear ring 294, so that the two clamping arms 298 on the bottom side of the support frame 295 are indexed. Then, the positioning structure 299 on the two clamping arms 298 is controlled to start, so that the second motor 2992 is started. Under the action of the second motor 2992, the second sector tooth piece 29934 and the first sector tooth piece 29932 cooperate to rotate. The three sector-shaped teeth 29935 mesh with each other, and respectively drive the clamping rod 299310 to make a longitudinal displacement on the support 2991 through the cooperation of the first push rod 29936 and the first connecting rod 29937, and the cooperation of the second push rod 29938 and the second connecting rod 29939 to approach, so that the clamping rod 299310 clamps and positions the brick on both sides of the brick, and then controls the cylinder 297 to start, and under the action of the cylinder 297, the two clamping arms 298 on both sides are displaced inwardly on the lower side of the carrier 295, so that the clamping blocks 2911 on the two clamping arms 298 are pressed against the two sides of the brick in the longitudinal direction, so as to clamp and grab the brick on four sides;

[0042] Fourthly, after the bricks are clamped, the bricks are controlled to move and placed on the stacking pallet on the lifting platform 3 for stacking. After the stacking is completed, the lifting platform 3 descends so that the motorized pallet contacts the brick conveyor 4. Then, under the action of the brick conveyor 4, the stacked bricks are moved and transported to the rotary conveyor 5, and the stacked bricks are packaged and formed by the baler 6.
