In order to save storage space, the general boxes are folded into a flat surface and stacked before loading. When in use, the box plate can be opened through the flip cover and plate mechanism to realize automatic unpacking.

[0003] In the prior art, a carton unpacking mechanism disclosed in the announcement number CN211593147U is arranged on one side of the belt line, and includes: a driving member, a first connecting rod, a second connecting rod, a connecting rod mounting seat, a suction cup mounting plate, and a plurality of vacuum suction cups fixed on the suction cup mounting plate; since the first connecting rod, the second connecting rod, the connecting rod mounting seat and the suction cup mounting plate form a parallelogram structure, according to the unstable characteristics of the parallelogram, the first connecting rod and the second connecting rod can rotate relative to the connecting rod mounting seat. Driven by the driving member, the first connecting rod and the second connecting rod rotate around the pivot point with the connecting rod mounting seat. During this process, the vacuum suction cup absorbs the folded carton and lifts it upward, thereby turning the carton into a three-dimensional state to achieve "unpacking". The unpacking mechanism has a simple structure, and the stroke of the vacuum suction cup is fixed, which can greatly improve the efficiency of unpacking. The carton unpacking mechanism of the utility model can automatically turn the folded carton from a plane state into a three-dimensional state, and the unpacking efficiency is high.

[0004] In the above patent, driven by the driving member, the first connecting rod and the second connecting rod rotate around the pivot point with the connecting rod mounting seat. During this process, the vacuum suction cup absorbs the folded carton and lifts it upward, so that the folded carton can be automatically changed from a flat state to a three-dimensional state, and the unpacking efficiency is high. However, in actual use, the above patent can only change the folded carton from a flat state to a three-dimensional state, but cannot open the three-dimensional carton that has been opened, which is not conducive to the secondary use of the carton. Summary of the invention

[0005] The utility model provides a cover and plate flipping mechanism for a gas meter box body to solve the problem that the folded carton can only be changed from a plane state to a three-dimensional state, but the three-dimensional carton that has been stretched cannot be opened, which is not conducive to the secondary use of the carton.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1, as Figures 1 to 4 As shown, a cover and flap mechanism of a gas meter box includes a first rotating cylinder 2 and a suction cup assembly 5 located above the first rotating cylinder 2;

[0025] A third rotary cylinder 9 is fixedly connected to one side of the first rotary cylinder 2, a connecting rod 8 is fixedly connected to the top output end of the third rotary cylinder 9, a side suction cup 7 is connected to one side of the connecting rod 8, and a fourth vacuum generator 11 is fixedly installed on the other side of the first rotary cylinder 2;

[0026] The suction cup assembly 5 includes a suction cup body 507, a deformation section 502 is fixedly connected to the bottom of the suction cup body 507, a vacuum cavity 501 is arranged inside the suction cup body 507, a reinforcing rib 506 is fixedly installed inside the vacuum cavity 501, the deformation section 502 made of polyurethane is suitable for adsorbing irregular objects with rough surfaces, hairy surfaces, etc., and can never firmly fix the box body, the deformation section 502 cooperates with the reinforcing rib 506 to enlarge the vacuum cavity 501, so that the area of ​​the vacuum cavity 501 is enlarged and the area is fixed, which effectively increases the suction force and ensures that the suction force is continuous and stable, so that the surface of the box body and the suction cup deformation section 502 fit closely to form a vacuum, and firmly fix the box body.

[0027] Embodiment 2. In addition to all the technical features of Embodiment 1, this embodiment also includes: an air suction hole 505 is opened above the vacuum cavity 501, and a connecting section 503 is threadedly connected to the top of the suction cup body 507. The air suction hole 505 cooperates with the airway 504 and the vacuum generator to help adjust the pressure difference and airflow, thereby ensuring the firm adsorption between the suction cup and the object. This arrangement improves the problem that most existing suction cups have weak adsorption force and are prone to sliding and falling when adsorbing the box.

[0028] An air passage 504 is connected above the connecting section 503 . The main function of the air passage 504 is to connect the vacuum generator with the inside of the suction cup. When the vacuum generator is started, the air pressure enters the inside of the suction cup through the air passage 504 .

[0029] A first vacuum generator 1 is fixedly installed at the bottom of the first rotary cylinder 2. Starting the first vacuum generator 1 facilitates the adsorption of the carton through the suction cup.

[0030] Embodiment 3, in addition to all the technical features of Embodiment 1, this embodiment also includes: a third vacuum generator 10 is fixedly installed at the bottom of the third rotating cylinder 9, and the third vacuum generator 10 is started in conjunction with the fourth vacuum generator 11 to facilitate the short-side carton to be adsorbed to the suction cup and sucked tightly.

[0031] The top output end of the first rotary cylinder 2 is fixedly connected with a bottom suction cup 3, and the bottom suction cup 3 cooperates with the suction cup body 507 to facilitate adsorption in the long side direction of the carton.

[0032] A second rotary cylinder 4 is connected to one side of the top of the first rotary cylinder 2, and a second vacuum generator 6 is fixedly installed on one side of the second rotary cylinder 4. Starting the second rotary cylinder 4 can make the long side of the carton 180 degrees with the carton body; this arrangement improves the problem that the flip cover and flap mechanism of the existing gas meter box can only change the folded carton from a flat state to a three-dimensional state, but cannot open the three-dimensional carton that has been stretched open, which is not conducive to the secondary use of the carton.

[0033] Working principle: When using the flip cover and flap mechanism of the gas meter box, first, adsorb the carton to the appropriate position and slightly clamp it; flip the second rotary cylinder 4 to drive the suction cup body 507 on both sides and the bottom suction cup 3 close to the long side direction of the carton; start the first vacuum generator 1 and the second vacuum generator 6 at the same time, adsorb the carton to the suction cup and suck it tightly; then the second rotary cylinder 4 flips the long side of the carton, so that the second rotary cylinder 4 brings the long side of the carton to 180 degrees with the carton body, and after the long side carton is completely unpacked, the third rotary cylinder 9 moves and also flips 90 degrees in the direction of the carton, and at the same time the third vacuum generator 10 cooperates with the fourth vacuum generator 11 to start, adsorb the short side carton to the suction cup and suck it tightly, and then the third rotary cylinder 9 flips, so that the carton is completely opened, and after the carton is packed, the third rotary cylinder 9 flips again, and the vacuum generator is turned off after it is in place, so that the carton in the short side direction is reset, and the long side direction is operated in the same way. In this way, the whole carton is closed. Repeating the above actions can realize the automatic unpacking of the carton; this arrangement improves the problem that the flap and flap mechanism of the existing gas meter box can only change the folded carton from a flat state to a three-dimensional state, but cannot open the three-dimensional carton that has been stretched open, which is not conducive to the secondary use of the carton; through the setting of the suction cup assembly 5, in which the deformation section 502 of the polyurethane material cooperates with the reinforcing rib 506, the vacuum cavity 501 is enlarged, the area of ​​the vacuum cavity 501 is enlarged and the area is fixed, the suction force is effectively increased, and the continuous and stable suction force is ensured, so that the surface of the box and the suction cup deformation section 502 are closely fitted to form a vacuum, firmly fix the box, and improve the problem that most of the existing suction cups have weak suction force and are prone to sliding and falling when adsorbing the box.
