[0026] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0027] For easier understanding, see Figure 1 to Figure 2The present embodiment provides an automatic stacking device for ton bags, including a frame 1, on which is provided a first conveyor belt 2 driven by a first transmission assembly, the first conveyor belt 2 being used to transport ton bags in a horizontal direction, a receiving assembly 3 being provided at the conveying end of the first conveyor belt 2, the receiving assembly 3 being rotatably connected to the frame 1, one end of the receiving assembly 3 being connected to a rotating motor 4 through a transmission mechanism, the rotating motor 4 being used to drive the receiving assembly 3 to rotate, and a stacking box 5 being provided vertically below the receiving assembly 3. After completing the previous operation, the ton bag is moved to the top of the first conveyor belt 2 for horizontal transportation when it is ready to be stacked. When the ton bag is continuously transported past the conveying end of the first conveyor belt 2 and gradually detaches from the first conveyor belt 2, the receiving assembly 3 located at the conveying end of the first conveyor belt 2 can receive the ton bag detached from the first conveyor belt 2 and keep the ton bag in a horizontal and static state above the receiving assembly 3. At this time, the rotating motor 4 is turned on, and the rotating motor 4 drives the receiving assembly 3 under the ton bag to rotate. The ton bag that loses the support below falls vertically into the stacking box 5 located below the receiving assembly 3, completing the stacking of the ton bag.

[0028] For easier understanding, see Figures 1 to 3There are two groups of receiving components 3 horizontally arranged side by side at the conveying end of the first conveyor belt 2, each group of receiving components 3 includes a rotating shaft 31, and the two side ends of the rotating shaft 31 are respectively rotatably connected to the frame 1, and four receiving plates 32 are fixedly arranged on the rotating shaft 31 at a circumferential interval of 90°. One side end of the rotating shaft 31 extends through the frame 1 and is connected to the rotating motor 4 through a transmission mechanism, and the rotating motor 4 is fixedly connected to the frame 1. When the ton bag is continuously transported through the conveying end of the first conveyor belt 2 and gradually detaches from the first conveyor belt 2, the receiving plates 32 on both sides receive the left and right sides of a ton bag respectively. At this time, the two rotating motors 4 are turned on at the same time. The rotating motors 4 drive the rotating shafts 31 on both sides to rotate 90° around their own axes, and then drive the receiving plates 32 on both sides to rotate 90° around the rotating shafts 31 as the center. The left receiving plate 32 rotates clockwise and the right receiving plate 32 rotates counterclockwise. At this time, the ton bag that has lost its lower support falls vertically to the stacking box 5 located below the middle of the receiving plates 32 on both sides due to its own gravity, completing the stacking of the ton bag; the two rotating shafts 31 both have a rotation cycle of 90°. After completing the rotation of 90°, the rotating motor 4 stops running, waiting for the next ton bag to detach from the first conveyor belt 2 and move to the top of the receiving plate 32. Repeat the above steps to stack the ton bags entering the top of the first conveyor belt 2 in the stacking box 5 in turn. All receiving plates 32 are provided with pulleys 33, which are rotatably connected to the receiving plates 32. During the movement, the ton bags will come into contact with the pulleys 33, thereby driving the pulleys 33 to rotate, so that the ton bags can move smoothly above the receiving plates 32 through the pulleys 33, reducing the friction between the ton bags themselves and the receiving plates 32, and avoiding the ton bags from being unable to move smoothly above the receiving plates 32 in the process of gradually leaving the first conveyor belt 2 due to the friction of the ton bags themselves, resulting in the ton bags folding, and ensuring that the ton bags can be stacked smoothly in sequence.

[0029] For easier understanding, please refer to Figure 1 to Figure 2 The first transmission assembly includes a first driving wheel 6 and a first driven wheel 7. The first driving wheel 6 is sleeved on the inner side of the conveying front end of the first conveyor belt 2, and the first driven wheel 7 is sleeved on the inner side of the conveying end of the first conveyor belt 2. The first driving wheel 6 and the first driven wheel 7 are respectively located on both horizontal sides of the first conveyor belt 2, and are rotatably connected to the frame 1. The first driving wheel 6 is connected to the first motor 8 through a transmission mechanism. The first motor 8 is used to drive the first driving wheel 6 to rotate. The first driving wheel 6 and the first driven wheel 7 cooperate with each other to drive the first conveyor belt 2 to transport the ton bags to be stacked.

[0030] For easier understanding, please refer to Figure 1 to Figure 2, a second conveyor belt 9 is provided below the first conveyor belt 2, and the second conveyor belt 9 is used to convey the stacking box 5. The second conveyor belt 9 is driven by a second transmission assembly, which includes a second driving wheel 10 and a second driven wheel 11. The second driving wheel 10 is sleeved on the inner side of the conveying front end of the second conveyor belt 9, and the second driven wheel 11 is sleeved on the inner side of the conveying end of the second conveyor belt 9. The second driving wheel 10 and the second driven wheel 11 are respectively located on both sides of the horizontal plane of the second conveyor belt 9, and are respectively rotatably connected to the frame 1. The second driving wheel 10 is connected to the second motor 12 through a transmission mechanism, and the second motor 12 is used to drive the second driving wheel 10 to rotate. The second driving wheel 10 and the second driven wheel 11 cooperate with each other to drive the second conveyor belt 9 to convey the stacking box 5. In actual use, the position of the stacking box 5 can be judged by the sensor to ensure that the second conveyor belt 9 accurately conveys the stacking box 5 to the bottom of the receiving plates 32 on both sides, waiting for stacking ton bags.

[0031] For easier understanding, please refer to Figure 1 to Figure 2 , a plurality of rollers 13 rotatably connected to the frame 1 are provided above the first conveyor belt 2. The rollers 13 are used to squeeze the ton bags to be stacked on the first conveyor belt 2, squeeze the ton bags flat, keep the ton bags flat before stacking, and stack them neatly in the stacking box 5, maximize the use of the stacking space of the stacking box 5, and at the same time, the air in the ton bags is expelled as much as possible through the rollers 13 to further ensure the flatness of the ton bags. A stop block 14 for correcting the conveying position of the ton bags is provided above the first conveyor belt 2. The stop block 14 is fixedly connected to the frame 1. The stop block 14 is located at the conveying front end of the first conveyor belt 2 relative to the rollers 13. The ton bags to be stacked first pass through the stop block 14 during the conveying process of the first conveyor belt 2 to correct the position of the ton bags. After the correction is completed, the ton bags are squeezed by the rollers 13 and gradually separated from the first conveyor belt 2. The correction action of the ton bags by the stop block 14 can ensure that the ton bags can be smoothly and flatly moved to the receiving plates 32 on both sides.

[0032] The working principle of this embodiment is as follows: the first conveyor belt 2 is connected to the processing station of the previous process, so that the ton bags that have completed the previous production process and are to be stacked are moved to the first conveyor belt 2 for transportation, and a plurality of empty stacking boxes 5 are placed on the second conveyor belt 9; the first ton bag transported on the first conveyor belt 2 is first corrected by the limit blocks 14 on both sides, and the position of the ton bag is adjusted to the center position of the first conveyor belt 2, and then the ton bag is squeezed and flattened by the pressing roller 13 and exhausted; as the first conveyor belt 2 continues to transport, the end of the ton bag begins to separate from the first conveyor belt 2, and when the first conveyor belt 2 gradually separates from some of the ton bags, the end of the ton bag begins to fall The ton bag sinks until it contacts the receiving plate 32. With the help of the pulley 33 on the receiving plate 32, the ton bag is smoothly separated from the first conveyor belt 2 and moves smoothly to the top of the two receiving plates 32. At this time, the two rotating motors 4 are turned on at the same time. The rotating motors 4 drive the rotating shafts 31 on both sides to drive the receiving plates 32 on both sides to rotate 90°. At this time, the ton bag located above the receiving plates 32 on both sides loses the support below. Due to its own gravity, the ton bag will fall vertically into the stacking box 5 located below the middle of the receiving plates 32 on both sides, completing the stacking of the first ton bag. Then repeat the above steps to stack the ton bags transported above the first conveyor belt 2 in the stacking box 5 in turn. When the number of ton bags stacked in a stacking box 5 reaches the preset value, the second motor 12 is turned on to drive the second driving wheel 10 to rotate and drive the second conveyor belt 9 to transport the stacking box 5, and the next empty stacking box 5 is transported to the bottom of the two receiving plates 32, waiting for the stacking of ton bags.

[0033] Although the present invention has been described using the above preferred embodiments, it is not intended to limit the scope of protection of the present invention. Any person skilled in the art may make various changes and modifications to the above embodiments without departing from the spirit and scope of the present invention, and the changes and modifications still fall within the scope of protection of the present invention.
