Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] Depend on Figures 1 to 5As shown, this utility model embodiment provides an automatic paper bag gripping and opening device, including a frame 6 and a storage mechanism 1, a conveying mechanism 2, an opening mechanism 3, and a support mechanism 4 disposed on the frame 6. The conveying mechanism 2 is positioned above the outlet end of the storage mechanism 1. Initially, the paper bag is placed horizontally on the outlet end, with the output end of the conveying mechanism 2 above it, thus gripping the bag from above and transferring it to the output end of the opening mechanism 3. At this point, the paper bag is in a vertical position with its opening facing upwards after being transferred by the conveying mechanism 2. Furthermore, the opening mechanism 3 is configured to allow its output end to move closer to or away from the conveying mechanism 2, so that when the output end of the opening mechanism 3 extends and approaches, it can grip the other side of the paper bag, and when it retracts and moves away from the conveying mechanism 2, it opens the paper bag. It should be noted that when the opening mechanism 3 grips and retracts the paper bag, the conveying mechanism 2 still needs to maintain a gripping state on the paper bag. Furthermore, a support mechanism 4 is positioned above the conveying mechanism 2 and the opening mechanism 3. The support mechanism 4 includes an opening cylinder 43. When the paper bag is opened by the opening mechanism 3, the opening cylinder 43 extends into the paper bag through the opening, providing internal support and maintaining the bag in an upright position with the opening facing upwards. The bottom end of the opening cylinder 43 has a through-hole 431. Finally, a feeding mechanism 5 is also included on one side of the support mechanism 4. The feeding mechanism 5 transfers the bagged material from the conveyor table 7 to the opening of the paper bag, allowing it to fall into the bag.

[0035] Preferably, the storage mechanism 1 includes a storage compartment 11, a paper feeding tray 12, and a paper-feeding rotating unit 13. The outlet end of the storage compartment 11 is located at the top. The paper feeding tray 12 is slidably disposed within the storage compartment 11. Multiple springs 14 are abutting between the bottom end of the paper feeding tray 12 and the bottom end of the storage compartment 11. The springs 14 cause the paper feeding tray 12 to move upward, so that the paper bag on top abuts against the paper-feeding rotating unit 13 at the top. The paper-feeding rotating unit 13 is disposed at the outlet end of the storage compartment 11, and then the paper bag at the top is rubbed towards the conveying mechanism 2 by the paper-feeding rotating unit 13. The springs 14 are placed at the four corners to ensure stability. Furthermore, multiple pins can be set at the bottom of the paper feeding tray 12 and the bottom plate of the storage compartment 11 to install the springs 14 and enhance the stability of the springs 14. Details are omitted here.

[0036] Furthermore, the paper-feeding rotation unit 13 includes a first rotating shaft 131 and a paper-feeding roller 132. The paper-feeding roller 132 is coaxially fixed on the first rotating shaft 131, and the first rotating shaft 131 is rotatably connected to the two side walls of the storage compartment 11. It also includes a first drive source 133, which is connected to the first rotating shaft 131 via a coupling. In this embodiment, the first drive source 133 is a servo motor, which drives the paper-feeding roller 132 to rotate via the first rotating shaft 131, thereby agitating the paper bag.

[0037] The paper feeding tray 12 can be further equipped with a limiting plate 121 in combination with a screw assembly. The limiting plate 121 can be moved by controlling the screw assembly, or the nut can be moved and adjusted on the threaded rod to limit the space for placing paper bags in the paper feeding tray 12, so as to accommodate paper bags of different sizes. This will not be elaborated on here.

[0038] Preferably, the conveying mechanism 2 includes a lead screw drive platform assembly 21 and a first gripping assembly 22. Two lead screw drive platform assemblies 21 are respectively disposed on both sides of the storage mechanism 1. The first gripping assembly 22 is provided with a first connecting rod 221, which is connected to the lead screw slider 213 of the lead screw drive platform assembly 21. The lead screw drive platform assembly 21 includes a motor 211, a lead screw 212, a lead screw slider 213, and a slide table 214 suitable for the movement of the lead screw slider 213. The motor 211 drives the lead screw 212 to move the lead screw slider 213 back and forth on the slide table 214. The specific structure is prior art and will not be described in detail here. By connecting the two ends of the first connecting rod 221 to the lead screw sliders 213 of the two lead screw drive platform assemblies 21 on both sides, and by synchronously driving the two motors 211, the first connecting rod 221 is moved back and forth.

[0039] Furthermore, the lead screw drive stage assembly 21 is also provided with an L-shaped guide groove 215 and a contour cam 216. The L-shaped guide groove 215 is provided on the side wall extending from one side of the slide table 214, and its front-to-back direction is the same as that of the lead screw 212. It includes a longitudinal part, a transverse part, and an arc-shaped part between the two. The contour cam 216 includes a guide part 2161 and a connecting part 2162. The cylindrical guide part 2161 is slidably connected to the L-shaped guide groove 215. The end of the first connecting rod 221 passes through the lead screw slider 213 and is fixedly connected to the connecting part 2162. By having the end of the first connecting rod 221 pass through the lead screw slider 213 and be fixedly connected to the connecting part 2162, wherein the guide part 2161 and the connecting part 2162 form an L-shape, when the lead screw slider 213 drives the first connecting rod 221 to move, the guide part 2161 will move along the L-shaped guide groove 215. Then, when the guide part 2161 moves from the longitudinal part of the L-shaped guide groove 215 through the arc part to the transverse part, the connecting part 2162 can be rotated by 90°, thereby causing the first connecting rod 221 to rotate, and simultaneously causing the first gripping component 22 to rotate by 90°.

[0040] Preferably, the first gripping component 22 further includes a second drive source 222, a first suction cup frame 223, and a plurality of first suction cups 224. The second drive source 222 is fixedly mounted on the first connecting rod 221, and the first suction cup frame 223 is connected to the output end of the second drive source 222. The first suction cup frame 223 is equipped with a plurality of first suction cups 224. The second drive source 222 is a telescopic cylinder, which controls the first suction cup frame 223 to extend and retract, thereby driving the plurality of first suction cups 224 on the first suction cup frame 223 to extend and retract. When the direction is vertical, the suction cups 224 can be brought close to the paper bag for gripping. At the same time, when the first connecting rod 221 changes its direction, the paper bag can be turned into a vertical state and moved closer to the opening mechanism 3.

[0041] Preferably, the opening mechanism 3 includes a mounting frame 31 and a second gripping component 32. The second gripping component 32 includes a third drive source 321, a second suction cup frame 322, and multiple second suction cups 323. The third drive source 321 is connected to the frame 6 via the mounting frame 31. The second suction cup frame 322 is connected to the output end of the third drive source 321 and is equipped with multiple second suction cups 323. The third drive source 321 is a telescopic cylinder. The telescopic cylinder drives the second suction cup frame 322 to move towards the conveying mechanism 2, thereby driving the multiple second suction cups 323 to move. The second suction cups 323 clamp the paper bag to the other side of the paper bag gripped by the conveying mechanism 2. When the second suction cups 323 return, the paper bag can be separated from both sides, thus completing the opening of the bag.

[0042] The first suction cup 224 and the second suction cup 323 are connected to a vacuum mechanism (not shown in the figure) to evacuate air in order to achieve suction and gripping, which will not be described in detail here.

[0043] Preferably, the support mechanism 4 includes a fourth drive source 41, a second connecting rod 42, and a bag-opening cylinder 43. The fourth drive source 41 is located at the top of the frame 6, and its output end is vertically downward and fixedly connected to the second connecting rod 42. The second connecting rod 42 is fixedly connected to the bag-opening cylinder 43. The fourth drive source 41 is a telescopic cylinder, which controls the second connecting rod 42 to move up and down, thereby driving the bag-opening cylinder 43 to extend into the opened paper bag and support the paper bag from the inside, allowing the material to be bagged to enter the paper bag more effectively. The bag-opening cylinder 43 has an opening at the top and a through-hole 431 at the bottom. Further, the feeding mechanism 5 includes a fifth drive source 51, a push plate 52, and a guide groove 53. The fifth drive source 51 is a telescopic cylinder, which controls the push plate 52 to push the material into the guide groove 53. Alternatively, the material can be directly guided into the guide groove 53 via the conveyor table 7. There are various methods, which will not be elaborated here. Finally, the material enters from above the opening cylinder 43 and enters the paper bag through the opening 431. When the fourth drive source 41 controls the opening cylinder 43 to move upward and leave the paper bag, the material can gradually and completely enter the paper bag, completing the bagging process.

[0044] Preferably, the system also includes a discharge platform 8, which is located below the support mechanism 4. The discharge platform 8 serves as a support for the bottom of the paper bag and also allows the filled paper bags to be moved from inside the frame 6 to the outside for retrieval after bagging. The entire process is automated, making bagging convenient and highly efficient.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
