[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] A bag unfolding mechanism for a packaging machine, such as Figures 1-3As shown, the system includes a machine base 1, a first support 2, a side support plate 3, a first drive assembly 4, and three sets of adsorption assemblies 5. The first support 2 is installed below the machine base 1. The first drive assembly 4 is mounted on the first support 2. The side support plate 3 and one set of adsorption assemblies 4 are mounted on the machine base 1 and located on both sides of the first drive assembly 4. A first mounting plate 6 is mounted on the first drive assembly 4. Two sets of adsorption assemblies 5 are symmetrically arranged on the first mounting plate 6. The first drive assembly 4 controls the first mounting plate 6 to move up and down and rotate horizontally.

[0019] In one embodiment, such as Figures 1-3 As shown, the first driving assembly 4 includes a lifting plate 41, a guide assembly 42, a first cylinder 43, and a swing cylinder 44. The lifting plate 41 is vertically slidably mounted on the first support 2 via the guide assembly 42. The first cylinder 43 is mounted on the first support 2 and drives the lifting plate 41 to move. The swing cylinder 44 is mounted on the lifting plate 41, and the first mounting plate 6 is mounted on the swing cylinder 44. The first cylinder 43 controls the lifting plate 41 to move up and down, and the swing cylinder 44 controls the first mounting plate 6 to drive the adsorption assembly 5 to reciprocate 180°. The unopened packaging bag is adsorbed from the side support plate 3 by the adsorption assembly 5, then rotated to the other side by the swing cylinder 44, and then adsorbed on the other side by another adsorption assembly 5 to open the packaging bag.

[0020] In the above embodiments, such as Figures 1-3 As shown, the guide assembly 42 includes a guide rod 421 and a guide sleeve 422. The guide sleeve 422 is disposed on the first bracket 2, and the guide rod 421 is fixed on the lifting plate 41 and slidably connected to the guide sleeve 422. Preferably, at least three sets of guide assemblies 42 are provided, and they are distributed at equal intervals around the first cylinder 43. In a specific embodiment, three or four sets of guide assemblies 42 are provided.

[0021] In one embodiment, such as Figures 1-3 As shown, the adsorption assembly 5 includes a second cylinder 51, a second mounting plate 52, and a suction cup 53. The second mounting plate 52 is mounted on the second cylinder 51, and the second cylinder 51 drives the second mounting plate 52 to move horizontally. The suction cup 53 is mounted on the second mounting plate 52. The suction cup 53 is an active suction cup, i.e., connected to a negative pressure generator, to achieve adsorption of the packaging bag. The second mounting plate 52 allows the suction cup 53 and the second cylinder 51 to be installed in a staggered manner, avoiding mutual interference.

[0022] In the above embodiments, such as Figures 1-3 As shown, at least two suction cups 53 are provided. Preferably, three suction cups 53 are provided, and the three suction cups 53 are distributed in an isosceles triangle.

[0023] In the above embodiments, such as Figures 1-3As shown, a side support block 54 is provided on the second mounting plate 52. In this embodiment, the support block 54 is located below the suction cup 53 and is used to support the packaging bag.

[0024] In one embodiment, such as Figures 1-3 As shown, a through slot is provided on the side support plate 3, and a third mounting plate 7 is provided on the side support plate 3. An adjustment slot 71 is provided on the third mounting plate 7, and the photoelectric sensor 8 is fixed to the adjustment slot 71. This allows the height position of the photoelectric sensor 8 to be adjusted. The light source of the photoelectric sensor 8 shines through the through slot onto the other side of the side support plate 3 to sense the packaging bag.

[0025] This utility model is used in conjunction with packaging bag production equipment, such as Figures 1-3 As shown, the packaging bag production equipment is the preceding equipment. The packaging bag production steps are as follows: a rolled cylindrical film is sealed at one end by a sealing device. After the film is pulled out a certain distance, it is cut by the sealing device and the cutting device to complete a packaging bag with one open end. The packaging bag moves down to the side support plate 3, and the length of the packaging bag is sensed by the photoelectric sensor 8. Then, the packaging bag is adsorbed by the adsorption component 5. After the packaging bag is cut by the packaging bag production equipment, the swing cylinder 44 drives the first mounting plate 6 to rotate 180°, moving the adsorbed packaging bag to the other side. Another adsorption component 5 adsorbs the other side of the packaging bag. The second cylinder 51 drives the suction cup 53 to move to both sides to complete the unfolding of the packaging bag.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. Any modifications or equivalent substitutions to the present utility model without departing from the spirit and scope thereof shall be covered within the protection scope of the claims of the present utility model.
