[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figs. 1-3 The M-side flattening device for packaging bags in this embodiment includes a bag opening mechanism and a flattening mechanism disposed on its right side. The bag opening mechanism is provided with a bag body 18 inside, and an inner film body 19 is inserted into the bag body 18. The bag opening mechanism is used to open the bag opening of the bag body 18 and the film opening of the inner film body 19. The flattening mechanism is used to integrate the inner film body 19 and the bag body 18.

[0018] In this embodiment, the leveling mechanism includes a linear module 1. Fixing members 2 are fixedly installed on the left and right sides of the bottom of the linear module 1. A bearing plate 3 is fixedly installed at the output end of the linear module 1. Slide rails 4 are fixedly installed on the left and right sides of the top of the bearing plate 3. Slider 5 is slidably installed on the front and rear sides of the slide rails 4. Slider connecting plates 6 are fixedly installed on the top of the front and rear sliders 5 respectively. Suction tubes 7 are fixedly installed on the opposite side of the slider connecting plates 6. A gear 9 is rotatably installed on the top of the bearing plate 3. A rack 8 with one end meshing with the gear 9 is fixedly installed on the top of the slider connecting plate 6. An adjusting cylinder 10 is fixedly installed on the top of the bearing plate 3. The output end of the adjusting cylinder 10 is fixedly connected to the front slider connecting plate 6. Two limiting seats 11 are fixedly installed on the top of the bearing plate 3. Positioning rollers 12 are rotatably installed on the top of the limiting seats 11. The positioning rollers 12 are in contact with the left and right racks 8 respectively.

[0019] It should be noted that the positioning roller 12 makes the rack 8 run more stably, which in turn makes the suction tube 7 operate more stably.

[0020] Specifically, when the bag opening mechanism opens both the bag opening of the bag body 18 and the inner membrane opening of the inner membrane body 19 simultaneously, the linear module 1 is activated to move the suction tube 7 to the left and insert it into the inner membrane body 19. Then, the adjusting cylinder 10 is activated to move the front slider connecting plate 6 forward on the slide rail 4 via the front slider 5. At this time, the right rack 8 drives the gear 9 to move, causing the left rack 8 to move backward, thereby driving the rear slider connecting plate 6 to move backward on the slide rail 4 via the rear slider 5. This achieves contact between the suction tube 7 and the inner membrane body 19, and slowly fits the edge of the inner membrane body 19 with the edge of the bag body 18, making subsequent bag opening shaping easier. After leveling, the external vacuum equipment is quickly shut off, the adjusting cylinder 10 is activated in reverse, and the above steps are reversed to restore the suction tube 7, achieving rapid leveling of the packaging bag.

[0021] In this process, after the suction tube 7 enters the inner film body 19, an external vacuum device is used to create a vacuum, so that the upper and lower surfaces of the suction tube 7 are in contact with the inner film body 19, and the inner wall is smoothed from top to bottom, thereby achieving a good fit between the packaging bag body 18 and the inner film body 19, and at the same time, better flatness.

[0022] In this embodiment, the bag opening mechanism includes an inner film suction cup 13, an outer bag suction cup 14, and a support plate 17. There are two inner film suction cups 13 and two outer bag suction cups 14. Suction cup connecting plates 15 are fixedly installed on both the front and rear sides of the lower inner film suction cup 13 and the lower outer bag suction cup 14. A telescopic cylinder 16 is fixedly installed on the left side of the support plate 17. A connector 20 is fixedly installed at the output end of the telescopic cylinder 16. The top of the upper inner film suction cup 13 and the upper outer bag suction cup 14 is fixedly connected to the connector 20. The suction cup tube 7 is located above the lower outer bag suction cup 14.

[0023] Specifically, when the external transport equipment transports the bag body 18 and the inner film body 19 between the upper and lower inner film suction cups 13 and the outer bag suction cup 14, since the lower inner film suction cup 13 and the outer bag suction cup 14 are fixed on the frame, the telescopic cylinder 16 is activated to drive the connecting piece 20 to lower the upper inner film suction cup 13 and the outer bag suction cup 14 to contact the bag body 18 and the inner film body 19 respectively. At this time, the external vacuum equipment is activated to open the bag opening of the upper and lower outer bag suction cups 14, and to open the film opening of the upper and lower inner film suction cups 13 that have not yet been fully inserted into the bag body 18. In conjunction with the leveling mechanism, the overall integration and leveling of the packaging bag inside and out is achieved.

[0024] In addition, the bag opening mechanism and the leveling mechanism are both fixed on the same frame. The leveling mechanism is fixed to the frame via the fastener 2. In the bag opening mechanism, the telescopic cylinder 16 is fixed to the frame via the support plate 17. The lower inner film suction cup 13 and the lower outer bag suction cup 14 are fixed to the frame via the suction cup connecting plate 15.
