[0010] The present invention is further configured such that: a through groove is provided on the side wall of two adjacent left clamping holes, and a through groove is also provided on the side wall of two adjacent right clamping holes; a connecting rod is provided between two adjacent left clamping rods, and a connecting rod is also provided between two adjacent right clamping rods; and several connecting rods are slidably inserted into the through grooves.

[0011] The present invention is further configured such that: the first driving component includes a first motor and a driving rod, the first motor is fixed inside the worktable, one end of the driving rod is fixed to the output end of the first motor, the other end of the driving rod slides through the worktable and is vertically upward, and the mounting bracket is fixed to the end of the driving rod that extends out of the worktable.

[0012] The present invention is further configured such that: the second driving component includes a second motor, a screw, and a guide rod; the second motor is fixed on the mounting bracket; one end of the screw is fixed on the output end of the second motor; the other end of the screw extends horizontally toward one side of the mounting bracket; one end of the guide rod is fixed on the mounting bracket; the other end of the guide rod extends horizontally toward the direction of the screw; one side of the mounting plate is threaded onto the screw, and the other side of the mounting plate is slidably fitted onto the guide rod.

[0015] Compared with existing technologies, the beneficial effects of this solution are:

[0016] This application significantly improves the automation level and efficiency of stacking operations through its integrated multi-degree-of-freedom structural design. By using a first drive component to rotate the mounting frame on the worktable, combined with a second drive component to drive the horizontal sliding of the mounting plate on the frame, the clamping device achieves a wide range of precise position adjustment within the horizontal plane. This allows the clamping plate to be raised and lowered to adapt to stacks of different heights. A third drive component drives the rotation of the clamping plate, providing the angle adjustment flexibility required for gripping and placing flour bags. Most importantly, the clamping components utilize clamping cylinders to synchronously drive several left and right clamping rods to move in opposite directions, enabling stable and adaptive clamping of flour bags of different sizes, effectively preventing slippage or damage to the packaging. This device reduces manual handling and positioning, significantly reducing labor intensity, increasing stacking speed, and ensuring stability during the stacking process.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] Example:

[0024] Reference Figures 1-4This application discloses a bagged flour stacking device, comprising a workbench 1, a mounting frame 2 rotatably mounted on the workbench 1, a mounting plate 3 horizontally sliding on one side of the mounting frame 2, a fixed plate 4 vertically adjustable below the mounting plate 3, a plurality of lifting cylinders 18 fixedly mounted on the mounting plate 3, the telescopic ends of the plurality of lifting cylinders 18 extending vertically downward and fixedly connected to the top of the fixed plate 4, a clamping plate 5 rotatably mounted on the bottom side of the fixed plate 4 away from the mounting plate 3, the clamping plate 5 having clamping components for clamping the bagged flour, the clamping components including a plurality of left clamping rods 8 and a plurality of right clamping rods 9, and further comprising a plurality of components for driving the plurality of left clamping rods 8 and the plurality of right clamping rods 9 along opposite directions. The clamping cylinder 10 moves towards the clamping plate 5, which is hollow. Several evenly arranged, elongated left clamping holes 6 and several evenly arranged, elongated right clamping holes 7 are formed on the bottom inner side of the clamping plate 5. These left and right clamping holes 6 and 7 are evenly and alternately distributed within the clamping plate 5. Several left clamping rods 8 slide through the corresponding left clamping holes 6, and several right clamping rods 9 slide through the corresponding right clamping holes 7. The bottom ends of the left and right clamping rods 8 and 9 are bent in opposite directions. The telescopic ends of the clamping cylinder 10 are fixedly connected to the ends of the left and right clamping rods 8 and 9, respectively. This effectively drives the left and right clamping rods 8 and 9 to move in opposite directions, fixing the bagged flour between the left and right clamping rods 8 and 9. The aforementioned lifting cylinder 18 and clamping cylinder 10 are both driven to extend and retract by connecting to the oil pump in the worktable 1. The connecting pipeline can be a long and flexible pipe. This type of connection is commonly used in the field of machinery and will not be elaborated on further in this article.

[0025] like Figure 2 and Figure 3 As shown, a through groove 11 is connected to the side wall of two adjacent left clamping holes 6, and a through groove 11 is also connected to the side wall of two adjacent right clamping holes 7. A connecting rod 12 is provided between two adjacent left clamping rods 8, and a connecting rod 12 is also provided between two adjacent right clamping rods 9. Several connecting rods 12 are slidably inserted into the through grooves 11. With the above design structure, the number of clamping cylinders 10 can be designed as two, and they are fixedly connected to the ends of one of the left clamping rods 8 and one of the right clamping rods 9, respectively. When the clamping cylinders 10 extend or retract, the connecting rods 12 drive the remaining left clamping rods 8 and right clamping rods 9 to move.

[0026] like Figure 1As shown, the workbench 1 is equipped with a first driving component for driving the mounting plate 3 to rotate horizontally around the workbench 1 as an axis. The maximum horizontal rotation angle driven by the first driving component is 90°. The first driving component includes a first motor 13 and a driving rod 14. The first motor 13 is fixed inside the workbench 1. One end of the driving rod 14 is fixed to the output end of the first motor 13, and the other end of the driving rod 14 slides through the workbench 1 and points vertically upward. The mounting bracket 2 is fixed to the end of the driving rod 14 that extends out of the workbench 1. The first motor 13 can effectively drive the driving rod 14 and the mounting bracket 2 fixed on the driving rod 14 to rotate.

[0027] like Figure 1 As shown, the mounting bracket 2 is equipped with a second driving component for driving the mounting plate 3 to slide horizontally. The second driving component includes a second motor 15, a screw 16, and a guide rod 17. The second motor 15 is fixed to the mounting bracket 2. One end of the screw 16 is fixed to the output end of the second motor 15, and the other end of the screw 16 extends horizontally towards one side of the mounting bracket 2. One end of the guide rod 17 is fixed to the mounting bracket 2, and the other end of the guide rod 17 extends horizontally in the direction of the screw 16. One side of the mounting plate 3 is threaded onto the screw 16, and the other side of the mounting plate 3 is slidably fitted onto the guide rod 17. The second motor 15 can effectively drive the screw 16 to rotate, thereby causing the mounting plate 3 to move horizontally along the direction of the screw 16 on the mounting bracket 2.

[0028] like Figure 1 and Figure 4 As shown, a third driving component is mounted on the fixed plate 4 to drive the clamping plate 5 to rotate. The maximum rotation angle of the clamping plate 5 driven by the third driving component is 90°. The third driving component includes a third motor 19 and two meshing drive gears 20. The third motor 19 is fixed on the fixed plate 4, with its output end pointing vertically downwards. A rotating rod 21 is fixed at the center of the clamping plate 5, with one end pointing vertically upwards and rotatably connected to the fixed plate 4 via a bearing. The two drive gears 20 are respectively fixedly sleeved on the output end of the third motor 19 and the rotating rod 21. This arrangement allows the flour to be clamped and rotated during stacking, enabling more bagged flour to be stacked and improving stacking stability.

[0029] Working principle:

[0030] During operation, the lifting cylinder 18 below the mounting plate 3 first drives the fixing plate 4 to descend, bringing the clamping component close to the bagged flour to be gripped. Next, the clamping cylinder 10 actuates, driving several left clamping rods 8 and right clamping rods 9 to slide in opposite directions along the staggered left clamping holes 6 and right clamping holes 7 at the bottom of the clamping plate 5. The bent portions at their bottom work together to securely clamp both sides of the bagged flour. After gripping, the lifting cylinder 18 raises the fixing plate 4 to a suitable height. Subsequently, the second motor 15 drives the screw 16 to move the mounting plate 3 onto the mounting frame 2. The flour bags are moved horizontally to the target stack position by sliding horizontally. At the same time, the first motor 13 drives the drive rod 14 to rotate the entire mounting frame 2 and clamping assembly horizontally. After reaching the stacking point, the clamping cylinder 10 is released, the left clamping rod 8 and the right clamping rod 9 are reset, and the flour bags are stacked on the stack position. When stacking in an alternating manner, the third motor 19 drives the rotating rod 21 to rotate through the meshing gear, and the clamping plate 5 and the clamped flour bags are rotated horizontally to adjust the horizontal orientation of the bags before stacking, thereby improving the stability of the stacking.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
