A limit strip 7 is symmetrically fixedly installed on the surface of one end of the stand 6. A connecting seat 10 is sleeved and connected on the surface of the first screw rod 9. The connecting seat 10 is slidably connected to the limit strip 7. A connecting frame 11 is fixedly connected to the surface of the connecting seat 10. The connecting frame 11 is fixedly connected to the connecting plate 12. During the movement, taking and carrying process, according to actual use needs, the horizontal sliding seat 3 and the vertical sliding seat 5 can be controlled in turn to move on the horizontal slide rail 2 and the vertical slide rail 4 respectively. When the horizontal and vertical positions reach the target, the first motor 8 on the stand 6 can be controlled to start operating, and the first screw rod 9 on its output end will rotate as needed. With the limiting effect of the limit strip 7, the connecting seat 10 and the connecting frame 11 will move in the vertical direction until the height required for the target step is reached;

[0031] The two short side surfaces of the connecting plate 12 are fixedly installed with a cross frame 13, the bottom surface of the connecting plate 12 is fixedly connected with a reinforcing rib 14, the bottom surface of the reinforcing rib 14 is fixedly connected with a support frame 15, the top surface of the support frame 15 is aligned with a first cylinder 16, the output end of the first cylinder 16 is fixedly installed with a sleeve 17, the surface of the support frame 15 is symmetrically fixed with suction cups 18 at the four corners, the two side surfaces of the support frame 15 are fixedly connected with side plates 19, and one end surface of the support frame 15 is fixedly connected with a fixing frame 22;

[0033] The surface of the fixed frame 22 is rotatably connected with the second cylinder 23, and the output end of the second cylinder 23 is fixedly connected with the connecting joint 24. The bottom surface of the support frame 15 is rotatably connected with the push frame 25 at one end edge, and the connecting joint 24 is rotatably connected with the push frame 25. In the process of transporting the corrugated cardboard box, in order to keep it stable, the pipeline can be connected in advance so that the suction cup 18 generates suction. Once the suction cup 18 is pressed against the upper end of the corrugated cardboard box, it can limit its displacement due to vibration to a certain extent, and can also play a certain buffering effect. When the box body is transported to the position to be transported, its position is not necessarily exactly aligned. At this time, the second cylinder 23 on the fixed frame 22 can be activated for operation, and the connecting joint 24 on its output end will push the push frame 25 to slowly change from a horizontal state to a vertical stand state. In this process, it will also slowly push against the surface of the corrugated cardboard box, and finally each carton will be transported and transported in the same posture, and then it will also remain aligned during palletizing, which is convenient for subsequent unified transfer and can also avoid the transportation problems caused by reasons such as inability to be transported.

[0034] The sleeve 17 is rotatably connected with the docking seat 26 and the linkage piece 27. The two side surfaces of the support frame 15 are symmetrically fixedly connected with the positioning seat 29. The surface of the positioning seat 29 is embedded with the first connecting shaft 30. The first connecting shaft 30 is rotatably connected with the alignment block 31. The bottom end surface of the alignment block 31 is fixedly connected with the upper plate 33. The upper plate 33 is fixedly connected with the second motor 39. The output end of the second motor 39 is fixedly connected with the second screw rod 40. The lower end of the upper plate 33 is provided with a lower plate 41. The surfaces of the upper plate 33 and the lower plate 41 are sleeved with a sliding rod 42. The second screw rod 40 is rotatably connected with the lower plate 41. One end surface of the lower plate 41 is located at the bottom end and fixedly installed with a mounting shell 43. The motor is fixedly installed inside the mounting shell 43. The output end of the motor is fixedly installed with a gasket 44. When clamping and lifting the corrugated box, the user can start the first cylinder 16 so that its output end begins to extend. Because the sleeve 17 is respectively connected with the linkage piece 27 and the sleeve piece 28 When connected at the connection position, the connection will extend outward, and the second connecting shaft 32 connected to the sleeve 28 will begin to flip inward around the first connecting shaft 30, so as to achieve lifting and clamping from the outside to the bottom. According to the length of the box, the user can unlock the sleeve bolt in advance, and then freely swing the two sets of upper plates 33. Under the influence of the first circle section 34, the docking rod 35 and the second circle section 36, the two sets of upper plates 33 will slowly move along the transverse groove 20 until they can match the length of the box, and then re-lock the sleeve bolt. According to the height of the box, the user can control the operation of the second motor 39 to make the second screw rod 40 start to rotate. With the limiting effect of the two sliding rods 42, the lower plate 41 will move downward a certain distance to meet the height requirement. For some small-volume boxes, it may not be easy to place them in the center position. The motor can be started to rotate the gasket 44 continuously. Under its driving effect, the small-volume box will move to the middle.

[0035] Working principle of the present invention: In the process of moving, picking up and carrying, according to the actual use needs, the horizontal slide seat 3 and the vertical slide seat 5 can be controlled in turn to move on the horizontal slide rail 2 and the vertical slide rail 4 respectively. When the horizontal and vertical positions reach the target, the first motor 8 on the vertical frame 6 can be controlled to start operating, and the first screw rod 9 on the output end will rotate as needed, and with the limiting effect of the limit bar 7, the connecting seat 10 and the connecting frame 11 will move in the vertical direction until they reach the height required for the target step. In the process of carrying the corrugated box, in order to keep it stable, the pipeline can be connected in advance so that the suction cup Suction is generated at the position 18. Once the suction cup 18 is pressed against the upper end of the corrugated box, it can limit its displacement due to vibration to a certain extent, and can also play a certain buffering effect. When the box is transported to the position to be transported, its position may not be exactly aligned. At this time, the second cylinder 23 on the fixed frame 22 can be activated to operate, and the connecting section 24 on the output end will push the push frame 25 to slowly change from a horizontal state to a vertical standing state. In this process, it will also slowly push against the surface of the corrugated box, and eventually each carton will be transported in the same posture, and then it will keep aligned during stacking. The first cylinder 16 is used for clamping and lifting the corrugated box, and the output end thereof begins to extend. Since the sleeve 17 is connected to the linkage piece 27 and the sleeve 28 at the connection position, the connection part extends outward, and the second connecting shaft 32 connected to the sleeve 28 begins to turn inward around the first connecting shaft 30, so as to realize the lifting and clamping from the outside to the bottom. According to the length of the box, the user can unlock the sleeve bolt in advance, and then freely swing the two sets of upper plates 33, and the first circle 34 and the butt joint 34 are connected. Under the influence of the rod 35 and the second section 36, the two sets of upper plates 33 will slowly move along the transverse groove 20 until they can match the length of the box, and then re-lock the bolt. According to the height of the box, the user can control the operation of the second motor 39 to make the second screw rod 40 start to rotate. With the limiting effect of the two sliding rods 42, the lower plate 41 will move downward a certain distance to meet the height requirement. For some small-volume boxes, it may not be easy to place them in the center position. The motor can be started to make the gasket 44 rotate continuously. Under its driving effect, the small-volume box will move to the middle.
