[0002] Weighing and packaging of materials has a wide range of applications in production practice. After the materials are weighed and bagged, they are transported by a conveyor line. Once in place, the bags are then picked up by suction cups and moved to a different location. However, because it cannot be guaranteed that the surface of each bag will be perfectly flat after bagging, there is a problem of unreliable bag suction due to air leakage at the edges of the suction cups during operation. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a suction bag structure that can perform a leveling action during suction bag operation, thereby ensuring reliable suction bag suction.

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0022] 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.

[0023] Figure 1-4The components include: main body 1, orifice plate 2, negative pressure pipe 3, pressure relief port 4, connection port 5, rubber suction cup 6, connecting seat 7, leveling mechanism 7, robotic arm connecting flange 7-1, bag suction device connecting flange 7-2, connecting screw 7-3, adjusting spring 7-4, etc.

[0024] like Figure 1-4 As shown, this utility model is a suction bag structure, including a main body 1, the lower end of which is connected to a rubber suction cup 6 to achieve adsorption of the bag body during operation.

[0025] A connecting seat 7 is installed on the top of the main body 1. The vertical air passage of the connecting seat 7 is connected to the inner cavity of the main body 1. The side of the connecting seat 7 is sealed and connected to the negative pressure pipe 3. The negative pressure pipe 3 is used to achieve the air extraction operation of the inner cavity of the main body 1, so that the rubber suction cup 6 can adsorb the bag.

[0026] The top structure of the connecting seat 7 is the connecting end face 5, which is connected to the leveling mechanism 7. This mechanism can level the mating surface between the rubber suction cup 6 and the bag, thereby ensuring a stable suction bag.

[0027] The leveling mechanism 7 includes a robotic arm connecting flange 7-1 and a bag suction device connecting flange 7-2 arranged parallel to each other. The robotic arm connecting flange 7-1 and the bag suction device connecting flange 7-2 are connected by a connecting screw 7-3. An adjusting spring 7-4 is sleeved on the connecting screw 7-3, and the two ends of the adjusting spring 7-4 respectively press against the robotic arm connecting flange 7-1 and the bag suction device connecting flange 7-2. The robotic arm connecting flange 7-1 is provided with a connecting hole for connecting the robotic arm.

[0028] A perforated plate 2 is provided inside the main body 1. The edge of the perforated plate 2 is fixedly connected to the inner wall of the main body 1, and a plurality of air holes are evenly distributed on the perforated plate 2. It can be understood that the main body 1 in this utility model is made of steel or aluminum alloy.

[0029] The perforated plate 2 divides the inner cavity of the main body 1 into an upper cavity and a lower cavity.

[0030] The negative pressure pipe 3 is equipped with a pressure relief port 4. When the bag is adsorbed and transferred to a suitable work position, the pressure relief port 4 releases the pressure inside the main body 1.

[0031] The rubber suction cup 6 is a compressible and foldable suction cup. During the suction operation, the robotic arm pulls the product onto the surface of the pocket. The negative pressure pipe 3 is connected to a vacuum device, thereby achieving vacuuming of the inner cavity of the main body 1 and the inner cavity of the rubber suction cup 6. After a large amount of gas is extracted from the rubber suction cup 6, the rubber suction cup 6 is suctioned into a compressed and folded state, thus reliably and stably adsorbing the pocket. It can be understood that the lower open end of the rubber suction cup 6 has an integrally connected horizontal extension on its outer surface.

[0032] The lower flange face of the body 1 is sealed to the upper connecting part of the rubber suction cup 6. It can be understood that the upper connecting part of the rubber suction cup 6 is fastened to the flange connecting face of the body 1 by bolts.

[0033] There is a gap between the connecting holes of the robotic arm connecting flange 7-1 and the bag suction device connecting flange 7-2 and the outer surface of the connecting screw 7-3. The gap allows for leveling of the robotic arm connecting flange 7-1, and the gap between the inner hole of the robotic arm connecting flange 7-1 and the outer surface of the connecting screw 7-3 increases the adjustment space during leveling operations.

[0034] like Figure 1-4 As shown, in operation, the leveling mechanism 7 is mounted on an external robotic arm. The robotic arm can move the product to transfer the packaging bag on the conveyor line to a suitable workstation. Specifically, when the robotic arm moves the product to above the bag on the conveyor line and presses it onto the bag, the leveling mechanism 7 ensures that the rubber suction cup 6 is flatly pressed against the bag. Then, the negative pressure pipe 3 starts to pump air, allowing the rubber suction cup 6 to firmly grip the bag. This allows the bag to be transferred to a suitable workstation. Once the bag is in the appropriate workstation, the pressure relief port 4 opens to release pressure, allowing the gripped bag to be lowered.

[0035] 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.
