[0002] In the field of material weighing and packaging technology, after the material is bagged and weighed to a qualified standard, the bag opening is sewn shut, and then the bag is conveyed via a conveyor line. Once in position, a suction cup structure sucks up the bag and transfers it to another workstation. However, due to uneven material inside the bag, air leakage occurs at the contact surface between the suction cup and the bag during suction. This results in the suction cup structure being unable to reliably transfer the bag during the suction process due to an unreliable suction. Summary of the Invention

[0015] Figure 1 This is a schematic diagram of the structure of this utility model.

[0016] Figure 2 This is a top view of the present invention. Detailed Implementation

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] Figure 1 , 2 The components include the main body 1, negative pressure pipe 1-1, orifice plate 1-2, suction cup 2, air conditioning and leveling assembly 3, robotic arm connecting flange plate 3-1, bag suction device connecting flange plate 3-2, guide rod 3-3, adjusting airbag 3-4, air guide pipe 3-5, etc.

[0020] like Figure 1 , 2 As shown, this utility model is a gas-regulating leveling suction bag structure, including a body 1, the body 1 having an inner cavity, and a perforated plate fixedly installed in the inner cavity, and a suction cup 2 sealed and connected to the lower flange connection surface of the body 1.

[0021] An air regulating and leveling assembly 3 is installed on the top of the main body 1. A guide rod 3-3 on the top of the main body 1 passes through the mechanical arm connecting flange plate 3-1 of the air regulating and leveling assembly 3. The bag suction device connecting flange plate 3-2 of the air regulating and leveling assembly 3 is fixed to the top surface of the main body 1. An adjusting airbag 3-4 is provided between the mechanical arm connecting flange plate 3-1 and the bag suction device connecting flange plate 3-2. The thickness of the adjusting airbag 3-4 can be adjusted.

[0022] The top of the main body 1 is provided with a negative pressure pipe 1-1, which connects to the inner cavity of the main body 1. During operation, a vacuum is drawn into the inner cavity of the main body 1 through the negative pressure pipe 1-1.

[0023] Understandably, to ensure that suction cup 2 can reliably and stably adhere to the bag, suction cup 2 has a certain degree of tension during the suction operation to ensure reliable and stable adhesion. Suction cup 2 is a rubber suction cup that can be compressed and folded.

[0024] The robotic arm connecting flange 3-1 includes an airbag cover plate, which is sealed to the upper open end of the adjusting airbag 3-4. A connecting plate is welded and fixed to both radial ends of the airbag cover plate. A guide rod 3-3 passes through the connecting hole of the connecting plate. There is a gap between the connecting hole of the connecting plate and the guide rod 3-3, so that reliable adjustment between the robotic arm connecting flange 3-1 and the guide rod 3-3 can be achieved.

[0025] The airbag cover is equipped with an air guide tube 3-5, which connects to the inner cavity of the adjusting airbag 3-4. During operation, the amount of gas in the adjusting airbag 3-4 is adjusted through the air guide tube 3-5, thereby adjusting the contact surface between the suction cup 2 and the pocket surface to ensure that the suction cup 2 can firmly adhere to the pocket.

[0026] Adjust the lower opening end of the airbag 3-4 to seal the connection of the suction bag connecting flange plate 3-2.

[0027] Furthermore, in order to ensure a reliable and stable connection between the suction cup 2 and the body 1, the lower flange connection surface of the body 1 is fastened to the suction cup 2 by bolts.

[0028] The negative pressure tube 1-1 is located on the top surface of the main body 1, next to the adjusting airbag 3-4.

[0029] The top of the main body 1 is provided with a pressure relief port so that the pressure inside the main body 1 can be released through the pressure relief port after the bag is adsorbed and transferred to a suitable work position.

[0030] like Figure 1 , 2As shown, in operation, this utility model is mounted on an external robotic arm via a connecting flange plate 3-1, and is driven by the robotic arm to perform its work. The negative pressure pipe 1-1 is connected to an external suction device. During bag suction, the robotic arm moves the utility model above the bag on the conveyor line, then moves it downwards until the suction cup 2 presses firmly against the bag. The negative pressure pipe 1-1 then suctions air from the inner cavity of the main body 1, creating a negative pressure state and achieving suction of the bag. It is understood that, due to different bag surface conditions, the robotic arm can adjust the pressure of the airbag 3-4 to achieve a tight seal between the suction cup 2 and the bag, ensuring reliable suction and moving the bag to a suitable work position.

[0031] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
