[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-9 The present invention provides a technical solution: Example 1: A gripping palletizing mechanism includes a conveyor belt 1, with a connecting box 2 bolted to one end of the conveyor belt 1. A processor is installed inside the connecting box 2, enabling sequential control of various electrical components. A first conveyor belt 23 is located inside the connecting box 2, along with a gripping and pushing mechanism that grips and pushes materials. A storage box 10 is fixedly connected to the side of the connecting box 2 away from the conveyor belt 1, containing several stacking mechanisms that limit the stacking of materials. A cover 9 is movably installed at the end of the storage box 10 away from the connecting box 2, allowing the stacking mechanisms to be sequentially stored inside the storage box 10 by opening the cover 9. A sensor 13 is fixedly connected to the outside of the connecting box 2. The sensor 13 can be selected according to its size and model, such as a photoelectric sensor, for quantity measurement.

[0018] The storage box 10 is equipped with a first pushing mechanism. The upper end of the storage box 10 is provided with a through cross-shaped slide groove 7. The cross-shaped slide groove 7 is equipped with a second pushing mechanism. The second pushing mechanism pushes the stacking mechanism. One end of the connecting box 2 is fixedly connected to a bracket 14. The inner side of the bracket 14 is movably connected to a lifting and conveying mechanism. The lifting and conveying mechanism includes an L-shaped connecting plate 19. Both ends of the L-shaped connecting plate 19 are fixedly connected to T-shaped blocks 21. The T-shaped blocks 21 slide in the T-shaped groove 15. By sliding the T-shaped blocks 21 in the T-shaped groove 15, the L-shaped connecting plate 19 can move smoothly.

[0019] T-slot 15 is opened on the outside of bracket 14. The upper end of L-shaped connecting plate 19 is movably connected to the second conveyor belt 20. The outer side of L-shaped connecting plate 19 is fixedly connected to the second limit strip 22. The outer side of bracket 14 is fixedly connected to the third telescopic cylinder 16. The output end of the third telescopic cylinder 16 is fixedly connected to the upper end of L-shaped connecting plate 19. The L-shaped connecting plate 19 is moved by the third telescopic cylinder 16.

[0020] Example 2: Based on Embodiment 1, in order to prevent the material from swaying when the first pusher plate 24 pushes the material, the gripping and pushing mechanism includes a first pusher plate 24, which is disposed inside the connecting box 2. Two first guide rods 4 are fixedly connected to one side of the first pusher plate 24 and are movably connected inside the connecting box 2. A first telescopic cylinder 3 is fixedly installed on the outside of the connecting box 2. The output end of the first telescopic cylinder 3 extends into the connecting box 2 and is fixedly connected to the first pusher plate 24. A clamping plate 30 is movably connected to one end of the first pusher plate 24. The upper end of the clamping plate 30 is fixedly connected to the output end of the connecting motor 31, which is fixedly connected inside the first pusher plate 24. When a certain amount of material enters the connecting box 2, the connecting motor 31 starts and drives the clamping plate 30 to rotate. The rotation of the clamping plate 30 limits and clamps several materials. By setting the clamping plate 30, the clamping plate 30 can grip and limit the material when the first pusher plate 24 pushes the material.

[0021] The stacking mechanism includes two limiting plates 5, which are connected to each other by two telescopic rods 28. The telescopic rods 28 enable the two limiting plates 5 to move synchronously. When the two limiting plates 5 move away from each other, the telescopic rods 28 are stretched. When the two limiting plates 5 move closer together, the telescopic rods 28 are compressed. Several hooks 27 are fixedly connected to the opposite surfaces of the two limiting plates 5. The upper and lower hooks 27 are connected by an elastic rope 26. The elastic rope 26 enables the two limiting plates 5 to move closer together when the first limiting bar 17 disengages from the upper limiting groove 25, thereby clamping and limiting the stacked materials. A limiting groove 25 is provided at one end of the limiting plate 5.

[0022] The first pushing mechanism includes a second push plate 32, which is disposed inside the storage box 10. Two second guide rods 11 are fixedly connected to one side of the second push plate 32. The second guide rods 11 are movably connected inside the storage box 10. The second push plate 32 can move smoothly through the setting of the second guide rods 11. A second telescopic cylinder 12 is fixedly connected to the outside of the storage box 10. The output end of the second telescopic cylinder 12 extends into the storage box 10 and is fixedly connected to the second push plate 32. A first limiting strip 17 is fixedly connected to one side of the second push plate 32.

[0023] The second pushing mechanism includes a slide plate 6, which slides into a cross-shaped groove 7. A lead screw 8 is screwed into the slide plate 6. One end of the lead screw 8 is movably connected to the cross-shaped groove 7, and the other end is fixedly connected to the output end of the drive motor 18. The drive motor 18 is fixedly installed in the storage box 10. When in use, the drive motor 18 can be used as a servo motor of a suitable model and size. A U-shaped rod 29 is movably connected inside the slide plate 6.

[0024] In addition, to achieve the above objectives, the present invention also provides a palletizer, including the above-described gripping palletizing mechanism.

[0025] Working principle: When in use, pull the U-shaped rod 29 upward to disengage it from the slide plate 6, loosen the screw to remove the box cover 9 from one end of the storage box 10, and put several stacking mechanisms composed of two limiting plates 5 into the storage box 10 in sequence. After the placement is completed, reinstall the box cover 9 and the storage box 10 together, and at the same time reinsert the U-shaped rod 29 into the slide plate 6. The slide plate 6 drives the U-shaped rod 29 to move, pushing the corresponding stacking mechanism. The second push plate 32 is moved by the second telescopic cylinder 12. The movement of the second push plate 32 causes the corresponding stacking mechanism to move, so that the stacking mechanism moves to the upper end of the L-shaped connecting plate 19. After the push is completed, the second push plate 32 stops moving. At this time, the first limiting strip 17 located on the outside of the second push plate 32 will be engaged in the limiting groove 25 at one end of the upper limiting plate 5. The first limiting strip 17 is engaged in the limiting groove 25 at the upper side, so that the upper limiting plate 5 cannot move. At the same time, the limiting groove 25 at one end of the lower limiting plate 5 will be engaged with the second limiting strip 22.

[0026] The conveyor belt 1 is aligned and connected with the material production line. The material produced by the production line enters the connecting box 2 through the conveyor belt 1. The material is transported to the position of the first push plate 24 by the first conveyor belt 23 in the connecting box 2. The sensor 13 records the amount of material entering the connecting box 2. When the amount of material entering the connecting box 2 reaches a certain amount, the connecting motor 31 starts and drives the clamping plate 30 to rotate. The rotation of the clamping plate 30 limits and clamps several materials. At the same time, the first push plate 24 starts to push several materials on the first conveyor belt 23.

[0027] After the material is pushed, it enters between the upper limiting plate 5 and the lower limiting plate 5. After the pushing is completed, the first telescopic cylinder 3 drives the first push plate 24 back to the initial position. At the same time, the connected motor 31 starts, causing the clamping plate 30 to return to the initial position. When the first push plate 24 pushes multiple sets of material into the space between the upper limiting plate 5 and the lower limiting plate 5, so that the lower limiting plate 5 is filled with material, the third telescopic cylinder 16 starts, driving the L-shaped connecting plate 19 connected to its output end to move. The limiting strip 17 is engaged in the upper limiting groove 25, and the lower limiting groove 25 is engaged with the second limiting strip 22. Therefore, when the L-shaped connecting plate 19 moves, it will drive the lower limiting plate 5 to move. After the lower limiting plate 5 moves a certain distance, the third telescopic cylinder 16 stops driving the L-shaped connecting plate 19 to move. When a certain amount of material accumulates in the connecting box 2 again, the first push plate 24 will move again to move the material, so that several groups of material are stacked together in sequence.

[0028] When the L-shaped connecting plate 19 moves to the lowest position, the material stacking is completed. The second telescopic cylinder 12 drives the second push plate 32 back to the initial position, and the first limiting strip 17 disengages from the upper limiting groove 25. At this time, under the elastic force of several elastic ropes 26, the upper limiting plate 5 moves downward, so that the stacked material is clamped between the upper limiting plate 5 and the lower limiting plate 5. The stacking mechanism with the material is conveyed away from the L-shaped connecting plate 19 by the second conveyor belt 20 at the upper end of the L-shaped connecting plate 19. At this time, the vehicle can transport the stacking mechanism with the material. At the same time, the third telescopic cylinder 16 drives the L-shaped connecting plate 19 back to the initial position.

[0029] After the second push plate 32 returns to its initial position, the drive motor 18 starts and drives the lead screw 8 connected to it to rotate. The rotation of the lead screw 8 drives the slide plate 6 to move. The movement of the slide plate 6 can push the new stacking mechanism to the notch of the storage box 10. At this time, the drive motor 18 stops, and the stacking mechanism can be pushed into the upper end of the L-shaped connecting plate 19 by restarting the second telescopic cylinder 12.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
