[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1 to 4 In this embodiment, a feeding mechanism for a ton bag packaging machine is provided, comprising a workbench 1, a mounting frame 3 is mounted above the workbench 1, a weighing bin 4 is mounted above the mounting frame 3, a weighing sensor 5 is mounted below the mounting frame 3, and a discharge port 6 is mounted on the workbench 1 below the weighing bin 4;

[0024] Above the workbench 1, support plates 7 are fixedly connected on both sides of the mounting frame 3, and a transfer mechanism 8 is rotatably connected to the support plate 7. A driving mechanism that can drive the transfer mechanism 8 to rotate intermittently is installed on the support plate 7. A screw conveyor 2 is installed on one side above the workbench 1, and one end of the screw conveyor 2 is located above the transfer mechanism 8;

[0025] The transfer mechanism 8 includes a rotating bin 81, which is rotatably connected to the support plate 7. The upper and lower ends of the rotating bin 81 are symmetrically provided with material storage troughs 83. A rotating disk 84 is rotatably connected inside the rotating bin 81. A motor 85 is fixedly installed at one end of the rotating bin 81, and one end of the motor 85 is inserted into the rotating bin 81 and connected to the rotating disk 84.

[0026] During use, the material is lifted to a high place by the screw conveyor 2 and dropped down. The material falls into the rotating bin 81, and the storage trough 83 inside the rotating bin 81 accumulates the material. When the material accumulates to a certain weight, the storage trough 83 flips over, and the material falls into the weighing bin 4 below, and continues to accumulate the material through the storage trough 83 on the other side. During the accumulation process, the overall weight of the weighing bin 4 is monitored by the weighing sensor 5 to improve the accuracy of weighing in the weighing bin 4.

[0027] When the material inside the weighing bin 4 is detected to be close to the target value, the storage trough 83 stops flipping, the motor 85 starts to drive the rotating disk 84 to rotate, and the material inside the upper storage trough 83 is transferred to the bottom through the rotating disk 84, thereby improving the accuracy inside the weighing bin 4 through a slower feeding speed.

[0028] In further embodiments, see Figure 2The weighing bin 4 has an opening below, with a gate 41 slidably connected to the inside of the opening. A telescopic rod 42 is fixedly mounted on one side of the weighing bin 4, with one end of the telescopic rod 42 fixedly connected to the gate 41. When the material inside the weighing bin 4 reaches the target value, the telescopic rod 42 extends, thereby driving the gate 41 to move. After the gate 41 moves, the weighing bin 4 is opened, and the material inside falls into the discharge port 6.

[0029] In further embodiments, see Figure 3 The driving mechanism includes a telescopic rod 71, the upper end of the telescopic rod 71 is fixedly connected to a rack 72, the rack 72 is slidably connected to the support plate 7, and one side of the rotating bin 81 passes through the support plate 7 and is fixedly connected to a gear 82, which is located on one side of the rack 72 and meshes with the rack 72.

[0030] The second telescopic rod 71 is extended to drive the rack 72 to move, the rack 72 moves to drive the gear 82 to rotate, the gear 82 rotates to drive the rotating bin 81 to rotate, and the second telescopic rod 71 is extended and shortened to drive the rotating bin 81 to rotate back and forth.

[0031] In further embodiments, see Figure 4 A plurality of material storage openings 841 are provided on the circumference of the rotating disk 84 , and the material storage openings 841 are evenly located on the circumference of the rotating disk 84 .

[0032] Through multiple storage ports 841, the material accumulated in the storage trough 83 falls into the storage port 841. As the rotating disk 84 rotates, the storage port 841 is located inside the lower storage trough 83 with the opening facing downward. The storage port 841 also opens downward, and the material inside falls into the weighing bin 4.

[0033] In further embodiments, see Figure 4 The middle of the storage trough 83 is recessed below the height of both ends of the storage trough 83, and the rotating disk 84 is located in the middle of the storage trough 83. The rotating disk 84 vertically penetrates the storage trough 83. This allows the material inside the storage trough 83 to be concentrated around the rotating disk 84, so that the rotating disk 84 can transport the material inside the storage trough 83 as much as possible.

[0034] In further embodiments, see Figure 1 The screw conveyor 2 is located above one end of the rotating bin 81, and the screw conveyor 2 and the motor 85 are not located on the same horizontal plane. This prevents the motor 85 from colliding with the feed port of the screw conveyor 2 during rotation.

[0035] In a further embodiment, the upper opening of the discharge port 6 is aligned with the lower opening of the weighing bin 4, and the upper opening area of the discharge port 6 is larger than the lower opening area of the weighing bin 4, so as to prevent the material from falling outside the discharge port 6.

[0036] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
