Their core function is to replace manual bagging operations, improve packaging efficiency and standardization, and they are widely used in industries such as food, daily chemicals, pharmaceuticals, and hardware.

[0003] While existing automatic bagging equipment has achieved automation of the bagging process to a certain extent, it still faces many technical bottlenecks. On the one hand, the accuracy of automatic bag gripping and conveying is insufficient; some equipment uses mechanical clamping, which is prone to unstable gripping that causes bags to fall, or positioning deviations during conveying that prevent bags from accurately reaching the bagging station, resulting in frequent equipment downtime for adjustments. Therefore, it is necessary to research an automatic bagging machine. Utility Model Content

[0004] The purpose of this invention is to provide an automatic bagging machine that solves the problems of insufficient gripping accuracy, large conveying and positioning deviation, and easy shutdown of existing automatic bagging equipment, so as to achieve stable bag gripping, accurate conveying and efficient bagging, and improve the stability of equipment operation and production efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] To address the clogging mechanism caused by differences in powder properties, proactive intervention is needed in the early stages of material accumulation. Traditional passive unblocking devices cannot adapt to the flow characteristics of different materials, necessitating the development of a graded treatment mechanism. Analysis of the powder's movement trajectory within the silo revealed that vertical accumulation and poor horizontal flowability are key factors causing clogging. Therefore, a rotating mechanical structure is proposed inside the silo to simultaneously achieve material crushing and directional conveying.

[0020] Therefore, refer to Figure 1 - Figure 10 This application discloses an automatic bagging machine, including a frame 1. A bag-lifting component for picking up packaging bags is installed on one side of the upper end of the frame 1. Bag-supporting components 9 for unfolding packaging bags are installed at both the front and rear ends of one side of the bag-lifting component. A bag-opening cylinder adjusting plate 22 is also fixed on one side of the bag-supporting component 9 on the frame 1. A cylinder 4 20 is installed on the bag-opening cylinder adjusting plate 22. A bag-opening cone 6 is fixed at the output end of the cylinder 4 20. A bag-feeding component is also installed at the lower end of the frame 1. A mounting base 29 is also fixed on the side of the bag-supporting component 9 away from the bag-lifting component. A robot arm 28 is installed on the upper end of the mounting base 29. A bag-gripping component 27 for gripping packaging bags is installed at the working end of the robot arm 28.

[0021] The bag assembly includes a cylinder 2 mounted on the frame 1. The output end of the cylinder 2 is fixed to a connecting plate 4 by screws. A cylinder 3 is fixedly mounted on the surface of the connecting plate 4. The output end of the cylinder 3 is fixed to a suction cup mounting piece 5 by screws. A suction cup 7 is mounted on the suction cup mounting piece 5. A suction cup protection post 18 is also mounted on the suction cup mounting piece 5.

[0022] The bag feeding assembly includes an empty bag tray 8, with a slider 13 mounted on its lower end. A slide rail 12 is also provided on the inner wall of the lower end of the frame 1, and the slider 13 is slidably mounted within the slide rail 12. A cylinder 16 is also mounted on the bottom wall of the frame 1. One end of the empty bag tray 8 extends to the frame 1 and is fitted with a directional caster 14 at its bottom. The output end of the cylinder 16 is connected to the side wall of the directional caster 14 via a spherical bearing. A fixing rod 24 is welded to the inner wall of the upper end of the empty bag tray 8. Rocker arms 26 are rotatably mounted on both the front and rear ends of the fixing rod 24. Empty bag pressure rollers 25 are rotatably mounted on the two rocker arms 26. An empty bag detection bracket 23 is also mounted on the side of the empty bag tray 8 near the bag-supporting cone 6. A photoelectric sensor is mounted on the empty bag detection bracket 23. After an empty bag alarm is triggered, the device is activated. When cylinder 16 is activated, it moves the directional caster 14 via the spherical bearing, pushing the empty bag tray 8 to slide along the slide rail 12, facilitating bag placement by the worker. After the bag is placed, the retracting cylinder is manually activated, and cylinder 16 returns the tray to its original position, conveying the empty bag to below the bag-lifting assembly. During this process, the empty bag pressure roller 25 presses the empty bag under the action of rocker arm 26 to prevent displacement. The photoelectric sensor on the empty bag detection bracket 23 monitors the empty bags in real time, and the equipment alarms when the bag is empty. Subsequently, cylinder 2 is activated, pushing the connecting plate 4 and cylinder 3 downward; cylinder 3 is activated, pushing the suction cup mounting part 5 into the empty bag tray 8, and the suction cup 7 adsorbs a single empty bag. Then, cylinder 3 resets, causing the empty bag to rise, and cylinder 2 resets, conveying the empty bag above the bag-supporting assembly 9.

During operation, cylinder 7 910 actuates, driving rocker arm 2 94 to rotate via Y-joint 97, moving lifting pallet 92 below the empty bag. Then, cylinder 5 91 extends (initially retracted), and cylinder 6 99 extends to clamp the lifting pallet 92 onto the bag. Cylinder 5 91 retracts downward, pulling the bag downward. Since the upper edge of the bag opening is firmly held by suction cup 7, the bag opening is pulled open. Finally, cylinder 4 20 actuates, pushing the bag opening cone 6 to insert into the bag opening, further opening the bag opening and maintaining its shape.

[0024] The bag-gripping assembly 27 includes a gripper frame 271, which is fixed to the working end of the robot arm 28. A clamping shaft 275 is installed on the lower side of the bottom end of the gripper frame 271. A clamping plate 272 and a clamping plate 273 are rotatably installed on the front and rear ends of the clamping shaft 275, respectively. A connecting plate 278 is fixed to the opposite end of the clamping plate 272 and the clamping plate 273 by studs. A connecting plate 277 is rotatably installed on the connecting plate 278. A cylinder 276 is also installed on the top of the gripper frame 271 near the clamping shaft 275. A mounting plate 274 is fixed to the output end of the cylinder 276. The connecting plate 277 is rotatably installed on the bottom surface of the mounting plate 274 on the side opposite to the connecting plate 278. The clamping parts of the clamping plates 272 and 273 are both arranged in an "L" shape, and when clamping, the clamping parts of the clamping plates 272 and 273 form a rectangular ring. During operation, the robotic arm 28 moves the bag-gripping assembly 27 to the opened empty bag; cylinder 8 276 actuates, pushing mounting plate 274 downwards, which, through connecting plate 277 and connecting plate 3 278, drives clamping plates 272 and 273 to rotate around clamping shaft 275, forming a rectangular ring to clamp the empty bag; the robotic arm 28 then moves the bag-gripping assembly 27 to the product to be bagged, completing the bagging process. During this process, photoelectric sensors on the photoelectric mounting bracket 19 monitor the bagging position to ensure accuracy.

[0025] An optical photoelectric mounting bracket 19 is also installed on the upper end of the empty bag detection bracket 23 on the side wall of the frame 1. An optical photoelectric sensor for monitoring the bag position is installed on the optical photoelectric mounting bracket 19.
