[0024] like Figures 1-7 The diagram illustrates a ton bag stacking device according to an embodiment of this disclosure. It includes a base frame 1, and further comprises: a support plate 2, support shafts 3, a lifting frame 4, and clamping plates 5. Each pair of adjacent clamping plates 5 is located on one side of a corresponding support shaft 3. The top of the base frame 1 has multiple sliding grooves, and the lifting frame 4 is slidably connected within these grooves. The support plate 2 is fixedly connected to the top of the base frame 1. Four support shafts 3 are provided, each mounted on the top of the base frame 1 via a support mechanism. The support mechanism is used to drive the support shafts 3 to move vertically. The lifting frame 4 is mounted within the base frame 1 via a drive mechanism, which is used to drive the lifting... The lowering frame 4 moves up and down. Each support shaft 3 has two clamping plates 5 at its bottom. Each pair of adjacent clamping plates 5 is set on the base frame 1 through a pull-down mechanism. The pull-down mechanism is used to pull the two clamping plates 5 down to place the ton bag on the support plate 2, and flip the four sides of the ton bag outward toward the four support shafts 3 respectively. The pull-down mechanism pulls down the edges of the ton bag. In conjunction with the support mechanism and the drive mechanism, the support shaft 3 moves up and down. This provides open support for the ton bag, adjusts the depth of the ton bag, shortens the distance the bagged product falls, and makes the bagged product inside the ton bag less likely to shift, thus improving the palletizing effect.

[0025] The support mechanism includes: a drive frame 6, a rotating ring 7, a rotating rod 8, a drive wheel 9, a transmission rod 10, and a support frame 11. Multiple rotating seats 25 are fixedly connected to the top of the base frame 1, and each rotating seat 25 is rotatably connected to a connecting shaft 26. The bottom ends of multiple drive frames 6 are rotatably connected to the multiple connecting shafts 26. There are two drive frames 6, both rotatably connected to the top of the base frame 1. A rotating ring 7 is fixedly connected to the top of the lifting frame 4, and a rotating rod 8 is rotatably connected inside the rotating ring 7. Both ends of the rotating rod 8 are rotatably connected to drive wheels 9. Each of the two drive frames 6 has two sliding grooves, and the two drive wheels 9 rotate... The ton bag is slidably mounted in two grooves. The top of each of the two drive frames 6 is fixedly connected to a transmission rod 10. The support frame 11 is rotatably connected to the top of the two transmission rods 10. The support shaft 3 is rotatably connected to the support frame 11. When the lifting frame 4 rises, it drives the drive wheel 9 to rise in the groove on the drive frame 6. Since the drive wheel 9 is driven by the lifting frame 4 to rise in a straight line, it rolls in the groove when it rises, thereby supporting the two drive frames 6 to swing, thus supporting the two transmission rods 10. When the transmission rods 10 are supported, they drive the support frame 11 and the support shaft 3 to rise or fall, thereby adjusting the depth of the ton bag.

[0026] The drive mechanism includes a drive screw 12, a drive block 13, a rotating gear 14, and a power assembly. The drive screw 12 is rotatably connected to the base frame 1. The drive block 13 is fixedly connected to the bottom end of the lifting frame 4. A screw hole is provided on the drive block 13, and the drive screw 12 is threaded into the screw hole. The rotating gear 14 is fixedly connected to one end of the drive screw 12. The power assembly is located in the base frame 1 and is used to drive the rotating gear 14 to rotate. The power assembly includes a drive gear 15 and a first motor 16. The drive gear 15 is located in the base frame 1 and meshes with the rotating gear 14. The first motor 16 is installed at the top of the base frame 1. The output end of the first motor 16 passes through the base frame 1 and is fixedly connected to the drive gear 15. The first motor 16 drives the drive gear 15 to rotate. When the drive gear 15 rotates, it drives the rotating gear 14 and the drive screw 12 to rotate, thereby driving the drive block 13 and the lifting frame 4 to rise or fall.

[0027] The pull-down mechanism includes: slide rods 17, pull-down brackets 18, counterweights 19, and tensioning components. Two slide rods 17 are provided, both slidably connected to the base frame 1. The pull-down bracket 18 is fixedly connected to the top ends of the two slide rods 17. Two clamping plates 5 are rotatably connected to the top ends of the pull-down brackets 18 via a rotating assembly. The counterweights 19 are fixedly connected to the bottom ends of the two slide rods 17. Two tensioning components are provided, respectively located at both ends of the two clamping plates 5, used to apply clamping force to the two clamping plates 5, causing them to clamp the edges of the ton bag. The rotating assembly includes: rotating shafts 20, rotating blocks 21, and operating levers 22. Two rotating shafts 20 are provided, both rotatably connected to the top ends of the pull-down bracket 18. Two rotating blocks 21 are fixedly connected to the bottom ends of each of the two clamping plates 5. Each pair of opposite rotating blocks... 21 are rotatably connected to two rotating shafts 20 respectively. The bottom ends of the two clamping plates 5 are fixedly connected to operating rods 22. The tensioning assembly includes: a fixed plate 23 and a tension spring 24. The two clamping plates 5 are fixedly connected to the fixed plates 23 respectively. When the four sides of the ton bag are turned outward on the support shaft 3, the operator pinches the two operating rods 22 to open the two clamping plates 5 and place the edge of the ton bag between the two clamping plates 5. Then the operator releases the two operating rods 22, and the tension spring 24 between the two fixed plates 23 tightens the two clamping plates 5, thereby clamping the edge of the ton bag. Then the weight of the counterweight 19 drives the two sliding rods 17 and the pull-down bracket 18 to descend, thereby tightening the edge of the ton bag. In conjunction with the lifting and lowering of the support shaft 3, the depth of the ton bag is adjusted.

[0028] Working principle: When the palletizer needs to load bagged products into ton bags, the ton bag is placed above the support plate 2, and the four sides of the ton bag are turned outwards towards the four support shafts 3. Then, the operator pinches the two operating levers 22 to open the two clamping plates 5, placing the edge of the ton bag between the two clamping plates 5. After that, the operator releases the two operating levers 22, and the tension spring 24 between the two fixing plates 23 tightens the two clamping plates 5, thereby clamping the edge of the ton bag. Then, the weight of the counterweight 19 drives the two sliding rods 17 and the pull-down bracket 18 to descend, thereby tightening the edge of the ton bag. The first motor 16 then... The drive gear 15 is driven to rotate, which in turn drives the rotating gear 14 and the drive screw 12 to rotate, thereby driving the drive block 13 and the lifting frame 4 to rise or fall. When the lifting frame 4 rises, it drives the drive wheel 9 to rise in the groove opened on the drive frame 6. Since the drive wheel 9 is driven by the lifting frame 4 to rise in a straight line, it rolls in the groove when it rises, thereby supporting the two drive frames 6 to swing, thereby supporting the two transmission rods 10. When the transmission rods 10 are supported, they drive the support frame 11 and the support shaft 3 to rise or fall, thereby adjusting the depth of the ton bag.
