This palletizing method has little space limitation, so the technology is mature, stable and efficient. In the prior art, when most palletizing devices are in use, their grabbing devices are fixed designs and can only grab products of corresponding sizes. When the size of the product exceeds its grabbing stroke, it is impossible to grab and stack larger products, resulting in certain limitations in its use and insufficient practicality. Therefore, it is necessary to redesign a product palletizing grabbing device to address the above problems. Utility Model Content

[0023] Two stabilizing rods 13 are slidably installed through the outer wall of the connecting plate 7, and the ends of the two stabilizing rods 13 are fixedly connected to the outer wall of the connecting frame 12. Limiting plates 14 are fixedly installed on the outer walls of the two stabilizing rods 13. A rotating plate 15 is rotatably installed on the inner wall of the connecting frame 12. Two first connecting frames 16 are fixedly installed on the bottom wall of the rotating plate 15. Two clamping plates 18 are slidably installed inside the connecting frame 12 through a connecting mechanism. The connecting mechanism includes a connecting rod 17 fixedly installed inside the connecting frame 12, and the connecting rod 17 slides through the two clamping plates 18.

[0024] A second connecting frame 19 is fixedly installed on the inner walls of the two clamping plates 18, and a connecting plate 20 is rotatably installed inside the two second connecting frames 19. The ends of the two connecting plates 20 are respectively rotatably connected to the inside of the first connecting frame 16 on the same horizontal line. Anti-slip tooth pads 21 are fixedly installed on the inner walls of the two clamping plates 18. An electric push rod 23 is fixedly installed on the outer wall of the connecting frame 12 through a supporting mechanism.

[0025] When the utility model is used, the bottom plate 1 can be conveniently moved by a plurality of pulleys 2. When stacking products, the conical rotor motor 9 can drive the gear 10 to rotate and engage the tooth plate 8, so that the connecting plate 7 can be forced to drive the slide block 6 to slide downward on the outer wall of the slide bar 4 through the cooperation of the limit rod 5, so that the connecting frame 12 can drive the two clamping plates 18 to move downward. At this time, the product can be placed between the two clamping plates 18. Then, the electric push rod 23 can drive one of the clamping plates 18 to move on the outer wall of the connecting rod 17. When one of the clamping plates 18 moves, it can drive the rotating plate 15 to rotate through a group of first connecting frames 16, connecting plates 20 and second connecting frames 19 on the same side. At this time, when the rotating plate 15 rotates, it can drive another clamping plate 18 to slide on the outer wall of the connecting rod 17 through another group of first connecting frames 16, connecting plates 20 and second connecting frames 19. In this way, the two clamping plates 18 can be brought close to each other and the product can be clamped and fixed through the anti-slip tooth pads 21. The anti-slip tooth pads 21 can increase the firmness of the product when it is clamped;

[0026] When the product is clamped and fixed, the conical rotor motor 9 reverses, so that the slider 6 slides upward on the outer wall of the slide bar 4 through the cooperation of the limit rod 5, thereby driving the clamped and fixed product to move upward. When it moves to a specified height, the cylinder 11 can drive the connecting frame 12 to move. At the same time, the connecting frame 12 can drive the two stabilizing rods 13 to slide on the outer wall of the connecting plate 7 when moving, thereby increasing the stability of the cylinder 11 during extension and retraction. As the cylinder 11 continues to extend, the connecting frame 12 can drive the clamped and fixed product to move to the top of the stacked product, and then the electric push rod 23 retracts, which can make the two clamping plates 18 move away from each other to clamp and fix the product, so that the product can be stacked at a high place.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
