Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5, Automatic weighing and flap-sealing cartoning and packing line, including a carton placement base 1, a placement board 2 is installed on the top of the carton placement base 1, and a buffer assembly 3 is arranged at the bottom of the placement board 2. A limiting assembly 5 is installed on the top of the placement board 2, and a finished product box 4 is installed on the top of the placement board 2. An unpowered conveyor 6 is arranged on one side of the carton placement base 1, and an automatic weighing machine 7 is installed on one side of the unpowered conveyor 6. A flap-sealing machine 8 is arranged on one side of the automatic weighing machine 7, and a powered conveyor 9 is installed on one side of the flap-sealing machine 8. An automatic strapping machine 10 is arranged on one side of the powered conveyor 9;

[0026] The buffer assembly 3 includes a connecting shaft 301. The bottom of the connecting shaft 301 is rotatably connected to a movable plate 302, and the bottom of the movable plate 302 is hinged to a moving plate 303. A fixed rod 304 is slidably connected to the inner wall of the moving plate 303. A first spring 305 is fixedly connected to one side of the moving plate 303. A damper 306 is installed at the bottom of the placement board 2, and a second spring 307 is sleeved on the outer surface of the damper 306;

[0027] The limiting assembly 5 includes a motor 501. The output end of the motor 501 is detachably connected to a lead screw 502 through a coupling, and a moving block 503 is threadedly connected to the outer surface of the lead screw 502. A connecting plate 504 is fixedly connected to the top of the moving block 503. A third spring 505 is installed on one side of the connecting plate 504, and a clamping plate 506 is fixedly connected to one end of the third spring 505.

[0028] Through the above technical solution, when the placement board 2 is subjected to gravity, it will move downward, drive the movable plate 302 to rotate through the connecting shaft 301, so that the moving plate 303 at the bottom of the movable plate 302 moves, and then the movement of the moving plate 303 is blocked under the action of the first spring 305, achieving the effect of buffering gravity. At the same time, with the cooperation of the second spring 307 and the damper 306, the downward pressure can be further buffered to prevent damage to the base for placing the finished product box 4 due to excessive pressure.

[0029] It is convenient for workers to load products into cartons on the unpowered conveyor 6 and push them into the automatic weighing machine 7 for automatic weighing of the products. After weighing, the products that meet the weight are sent to the flap-sealing machine 8 for carton sealing operations. Those that do not meet the weight will stop and alarm, waiting for manual processing. The cartons are sent to the flap-sealing machine 8 to first fold the front cover of the carton, then fold the back cover, and finally fold the two side covers back at the same time, and then use a taping device to seal the tape on the carton. The cartons are sent to the automatic strapping machine 10 through the powered conveyor 9 to start automatically strapping the packing belts onto the cartons. The automatic strapping machine 10 can be set to automatically strap one to three packing belts according to requirements.

[0030] Specifically, the placement plate 2 and the movable plate 302 form a rotating structure through the connecting shaft 301, and the movable plate 302 is arranged between the connecting shaft 301 and the moving plate 303.

[0031] Through the above technical solution, when pressure is generated on the placement plate 2, it is convenient for the connecting shaft 301 to drive the movable plate 302 to rotate. Since the two movable plates 302 are arranged in opposite directions, the two movable plates 302 rotate in opposite directions, driving the two moving plates 303 to move in opposite directions.

[0032] Specifically, one end of the fixed rod 304 penetrates through the inner walls of the moving plate 303 and the first spring 305 at the same time, and the number of the first springs 305 is two.

[0033] Through the above technical solution, it is convenient for the moving plate 303 to slide on the fixed rod 304 during the moving process, so that the moving plate 303 remains stable during the moving process. And when the moving plate 303 moves outwards, it will be restricted by the first spring 305, causing the first spring 305 to be compressed. Then the force of the moving plate 303 moving outwards is hindered, achieving the effect of buffering the downward force on the placement plate 2.

[0034] Specifically, the carton placement base 1 and the placement plate 2 form an elastic structure through the second spring 307, and the number of the second springs 307 is two.

[0035] Through the above technical solution, it is convenient for the placement plate 2 to further buffer the downward force through the second spring 307 and the damper 306, further improving the buffering effect on the pressure.

[0036] Specifically, the motor 501 and the moving block 503 form a moving structure through the lead screw 502, and the external thread of the lead screw 502 matches the internal thread of the moving block 503.

[0037] Through the above technical solution, when the motor 501 is started, it is convenient for the lead screw 502 to rotate and drive the moving block 503 to move at the same time. Since the thread directions on both sides of the lead screw 502 are opposite, and the two moving blocks 503 are symmetrically arranged on both sides of the lead screw 502, the two moving blocks 503 move relatively.

[0038] Specifically, the connecting plate 504 and the clamping plate 506 form an elastic structure through the third spring 505, and the third spring 505 is arranged between the connecting plate 504 and the clamping plate 506.

[0039] Through the above technical solution, it is convenient for the moving block 503 to drive the connecting plate 504 to move relatively during the moving process. The finished product box 4 can be clamped and limited by the clamping plate 506, and under the action of the third spring 505, the force applied to the finished product box 4 can be buffered, thereby reducing the damage to the outside of the finished product box 4.

[0040] Working principle: When using this automatic weighing, folding, sealing and packing line, first, manually load the products into the cartons on the unpowered conveyor line 6 and push them into the automatic weighing machine 7 for automatic weighing of the products. After weighing, the products that meet the weight are sent to the folding and sealing machine 8 for sealing operation, and the products that do not meet the weight are stopped and alarmed, waiting for manual handling. The cartons are sent to the folding and sealing machine 8 to first fold the front cover of the carton, then the rear cover, and finally fold the two side covers back at the same time, and then use the tape applicator to seal the tape on the carton. The cartons are sent into the automatic strapping machine 10 by the powered conveyor 9 to start automatically strapping the packing tape to the cartons. The automatic strapping machine 10 can be set to strap one to three packing tapes as required. Then the staff places the finished product box 4 on the placing plate 2. As the finished product boxes 4 accumulate, the placing plate 2 will move downward. The placing plate 2 will drive the movable plate 302 to rotate through the connecting shaft 301. The rotation of the movable plate 302 drives the moving plate 303 to move outward, and then the moving plate 303 compresses the first spring 305, restricting the force for the moving plate 303 to move outward. At the same time, the placing plate 2 can further buffer the downward force through the second spring 307 and the damper 306, further improving the buffering effect on the pressure. Then start the motor 501. The motor 501 drives the lead screw 502 to rotate. The lead screw 502 drives the two moving blocks 503 to move relatively. The moving blocks 503 drive the connecting plate 504 to move inward. The connecting plate 504 drives the clamping plate 506 to move inward through the third spring 505 to clamp and fix the finished product box 4. At the same time, under the action of the third spring 505, the force applied to the finished product box 4 can be buffered, thereby reducing the damage to the outside of the finished product box 4. This completes all the work. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit. The scope is defined by the appended claims and their equivalents.
