[0135] like Figure 1 , Figure 2 and Figure 6 As shown, in this embodiment, the optimization further includes a tipping mechanism 10, and the tipping mechanism 10 includes:

[0136] A power source 101 is arranged at the rear side of the two front brackets 41;

[0137] The ball screw 102 is arranged on the output shaft of the power source 101;

[0138] The movable plate 103 is threadedly arranged on the ball screw 102;

[0139] The push plate 104 is disposed between the rear sides of the two movable plates 103 , and the push plate 104 is located at the rear side of the ton bag 2 .

[0140] In this technical solution, the output shaft of the power source 101 is connected to the ball screw 102, so that the power source 101 provides power to drive the ball screw 102 to rotate, so that the moving plate 103 drives the push plate 104 to move forward, and the push plate 104 pushes down the raised ton bag 2 to assist the user in collecting it.

[0141] Overall workflow:

[0142] When a proper amount of large-packaged salt is loaded into the ton bag 2, the device is easily moved to the position where it needs to be unloaded through the universal wheel 62, then the positioning plate 74 is lowered, and the servo motor 84 is started. The servo motor 84 drives the rotating rod 82 to rotate, thereby driving the gear 1 83 installed on the rotating rod 82 to rotate. The gear 1 83 meshes with the gear 2 86 on the rotating rod 85, so that the rotating rod 85 also starts to rotate, and the fan gear 89 on the left meshes with the rack 88, so that the rack 88 slides upward in the through groove 87. This action will lift the top plate 810, thereby lifting the ton bag 2 placed on the top plate 810. When the lifting mechanism 8 lifts the ton bag 2, the pressure sensor 9 at the bottom of the top plate 810 starts to detect the weight of the large-packaged salt in the ton bag 2. The detected weight value is transmitted to the data processing unit 91 through the circuit. The data processing unit 91 processes this information and sends the result to the display unit 92 so that the operator can The weight changes during the bagging process are monitored in real time to ensure that the weight of each bag of salt meets the preset standard. When the ton bag 2 is raised to a suitable position, the servo motor 84 is turned off. At this time, the push plate 104 should be located at the waist of the ton bag 2. Then the power source 101 is started. The power source 101 provides power to drive the ball screw 102 to rotate. The ball screw 102 is threadedly connected to the movable plate 103, so that the movable plate 103 drives the push plate 104 to move forward, and the push plate 104 pushes down the ton bag 2, so that the ton bag 2 falls on the unloading site. Then the power source 101 drives the ball screw 102 to rotate in the opposite direction, so that the movable plate drives the push plate 104 to move backward and reset. In this way, through the cooperation of these mechanisms and sensors, the large-package automatic bagging device can efficiently and accurately complete the salt bagging work, and monitor the weight data during the bagging process in real time, and can assist users to unload the packaged ton bags 2, saving manpower and improving work efficiency.
