Description

Technical Field

[0001] This utility model relates to the technical field of automatic bag opening machines for packaging bags, specifically an automatic bag opening machine for packaging bags. Background Technology

[0002] An automatic bag opening machine is an automated device specifically designed to automatically open various types of packaging bags in preparation for subsequent filling processes.

[0003] Currently, existing automatic bag opening machines typically use suction cups to pull open the bag opening. However, this method often fails to open thick bags due to insufficient suction. Furthermore, the heat-sealing process causes the bag opening to stick, making it difficult to effectively separate the bags using only the lateral pulling force of the suction cups. This results in a low overall success rate, severely impacting packaging production efficiency and product quality stability. Additionally, when using the machine, the bag is simply placed within the preparation structure. When the suction cups attempt to remove the bag, the bag tends to move, making it difficult for the suction cups to accurately remove the bag, leading to inconvenient bag retrieval.

A connecting block 15 is fixedly connected to the movable end of the electric telescopic rod 13. A second suction cup 16 is fixedly connected to one side of the connecting block 15. A fixing block 17 is fixedly connected to one side of the storage frame 1. A nozzle 21 is fixedly connected inside the fixing block 17. A connecting air pipe 18 is fixedly connected to the upper part of the nozzle 21. A limiting rod 4 is arranged on one side of the storage frame 1. A pressure plate 5 is sleeved on the outer side of the limiting rod 4. The pressure plate 5 is located on the upper part of the packaging bag body 6.

[0026] Specifically, the storage frame 1 has an opening at the bottom for picking up materials, and openings on both sides for discharging materials. The first suction cup 14 and the second suction cup 16 are provided with a transmission structure at their bottom, while the first suction cup 14 is provided with an inclined conveying structure at its top.

[0027] Please see Figures 1 to 2 The lower part of the storage box 1 is rotatably connected to the reciprocating screw of the first transmission structure 9, and the reciprocating screw of the first transmission structure 9 is threadedly connected to the connecting frame 10. The first transmission structure 9 is composed of a servo motor and a reciprocating screw.

[0028] Specifically, the servo motor is connected to the external control structure via wires, and the servo motor of the first transmission structure 9 is fixedly connected to the support frame 8.

[0029] Please see Figure 5 A second transmission structure 19 is fixedly connected to one side of the connecting frame 10. The output shaft of the second transmission structure 19 is fixedly connected to a movable plate 20. The second transmission structure 19 consists of a servo motor and an output shaft.

[0030] Specifically, the servo motor is connected to the external control structure via wires, and the output shaft of the second transmission structure 19 is rotatably connected to the connecting frame 10.

[0031] Please see Figures 1 to 3 A support spring 2 is sleeved on the outside of the limiting rod 4. The lower end of the support spring 2 is connected to the pressure plate 5. A fixing rod 3 is fixedly connected to the upper part of the storage frame 1. The lower part of the fixing rod 3 is connected to the limiting rod 4.

[0032] Specifically, one side of the pressure plate 5 is attached to the storage frame 1, and the lower part of the fixing rod 3 is connected to the support spring 2.

[0033] Please see Figures 1 to 2 , Figure 4 , Figure 6 The upper part of the support frame 8 is fixedly connected to the support column of the sensor group 11. The first suction cup 14 and the second suction cup 16 are respectively connected to the vacuum pump through the air pipe, and the connecting air pipe 18 is connected to the high pressure air pipe.

[0034] Specifically, the transmission assembly 11 consists of multiple sensors with different functions. The sensor assembly 11 is used to detect the rotation angle of the movable plate 20, the extension and retraction position of the electric telescopic rod 13, the status of the packaging bag body 6, and the start of the vacuum pump.

[0035] Please see Figure 1 , Figure 4 , Figure 6 The first suction cup 14 corresponds to the second suction cup 16, and the nozzle 21 is located between the first suction cup 14 and the second suction cup 16. The nozzle 21 is tilted towards the center.

[0036] Specifically, the nozzle 21 penetrates the fixing block 17, and the first suction cup 14 and the second suction cup 16 both penetrate the corresponding connecting block 15 and the movable plate 20.

[0037] During use, the main body 6 of the packaging bag is placed inside the storage frame 1. The first transmission structure 9 is activated, and the servo motor drives the reciprocating screw, causing the connecting frame 10 to move upward until the second suction cup 16 on the flat movable plate 20 adheres to the main body 6 of the packaging bag. Through the external control structure, the vacuum pump is controlled to suck air into the second suction cup 16, causing the second suction cup 16 to adhere to the main body 6 of the packaging bag. Then, the connecting frame 10 is moved downward, and the second suction cup 16 removes the main body 6 of the packaging bag through the opening at the bottom of the storage frame 1. The second transmission structure 19 is then activated, and the servo motor drives the movable plate 20 to rotate through the output shaft until the corresponding sensor of the sensor group 11 detects it and stops rotating. At the same time, the electric telescopic rod 13 is activated, pushing the connecting block 15 outward, so that the first suction cup 14 adheres to the main body 6 of the packaging bag. The vacuum pump then sucks up the first suction cup 14, and the electric telescopic rod 13 retracts, causing the bag opening to open. The combination of the first suction cup 14, the second suction cup 16, and the electric telescopic rod 13 achieves the effect of suction and opening the bag. When the electric telescopic rod 13 retracts, the external control structure opens the high-pressure air pipe, blowing air into the connecting air pipe 18, which is then sprayed out through the nozzle 21. The nozzle 21 corresponds to the bag opening, thus blowing air into the bag opening and filling the inside of the bag body 6 with air, thereby increasing the efficiency of opening the bag opening. Through the coordinated arrangement of the connecting air pipe 18, the fixing block 17, and the nozzle 21, air can be blown into the bag opening during use, thereby increasing the opening efficiency and achieving the goal of improving the opening effect of the bag.

[0038] After bending the main body 6 of the packaging bag, it is inserted through the side opening of the storage frame 1. Then, the main body 6 of the packaging bag is laid flat in the storage frame 1. The pressure plate 5 moves downward under its own weight, pressing down and fixing the main body 6 of the packaging bag, so that the second suction cup 16 is completely attached to the main body 6 of the packaging bag, making it easy to pick up. The pressure plate 5 has the effect of pressing down and fixing the main body 6 of the packaging bag. The limiting rod 4 limits the pressure plate 5, and the support spring 2 applies pressure to the pressure plate 5 again, increasing the downward pressure. Through the cooperation of the limiting rod 4, the fixing rod 3 and the support spring 2, pressure can be applied to the pressure plate 5 during use, thereby increasing the downward pressure and achieving the purpose of convenient removal of the packaging bag.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
