[0016] The following is combined with Figure 1-5 The specific implementation methods of the utility model are further described in detail.

[0017] Embodiment 1, the technical solution is as follows. Specifically, when the present application is in use, the open end of the packaging bag is placed between the two movable frames 7. When the driving motor 6 provided on the mounting frame 1 rotates forward, it drives the horizontal axis 4 to rotate forward. When the horizontal axis 4 rotates forward, the threaded portion 5 thereon rotates synchronously. Since the two threaded portions 5 are symmetrically arranged, that is, the thread rotation directions are opposite, the two movable frames 7 will move toward each other along the horizontal axis 4 driven by the threaded portions 5, and the adsorption opening components 8 on the two movable frames 7 will also move relatively close to each other, and finally the suction cups 18 of the two adsorption opening components 8 are respectively abutted against the two sides of the opening end of the bag, and the adsorption device can generate negative pressure in the adsorption tube 17 through the vacuum negative pressure pump 14, the metal hose 15 and the multi-way connector 16, so that the suction cup 18 produces an adsorption effect, and the suction cups 18 of the two adsorption opening components 8 respectively adsorb the two sides of the packaging bag.

[0018] Then, the driving motor 6 is started to reverse, and the reverse rotation of the driving motor 6 will drive the horizontal axis 4 to reverse, and then the two threaded parts 5 will drive the movable frame 7 together with the adsorption opening component 8 to move in opposite directions, that is, the suction cups 18 on the two groups of adsorption opening components 8 move relatively away from each other, and the suction cups 18 on the two groups of adsorption opening components 8 are in an adsorption state to the packaging bag, and then the opening operation of the open end of the packaging bag can be completed.

[0019] Embodiment 2, based on embodiment 1, further, in order to prevent the suction opening assembly 8 from sliding onto the packaging bag sleeve 21 during the process of opening the packaging bag, an auxiliary clamping assembly 9 is provided to cooperate with the suction opening assembly 8 . Specifically, as mentioned above, when the driving motor 6 rotates forward and moves toward each other through the adsorption opening components 8 on the two moving frames 7, the controller 2 receives the information that the driving motor 6 rotates forward and is in a silent standby state. When the driving motor 6 reverses and drives the adsorption opening components 8 on the two moving frames 7 to move away from each other, that is, when the two groups of adsorption opening components 8 adsorb the packaging bag opening, the controller 2 receives the information that the driving motor 6 is reversed, and then the driving motor 6 will drive the clamping motor 13 on the positioning plate 10 to rotate forward for a set stroke and then reverse and reset. When the clamping motor 13 rotates forward for a set stroke, the longitudinal axis 11 together with the splint 12 will rotate accordingly by a corresponding angle, and then the splint 12 will separate from the fixed plate, and then the clamping motor 13 will reverse and reset. During the reverse and reset process, the longitudinal axis 11 together with the splint 12 will reverse and reset accordingly, and during the reversal of the splint 12, the edge of the packaging bag can be pulled, so that the packaging bag is clamped between the splint 12 and the fixed plate, thereby stabilizing the packaging bag and preventing the packaging bag from sliding on the sleeve 21.

[0020] Embodiment 3, on the basis of embodiment 2, in the present application, the adsorption tube 17 is evenly connected to the bottom of the movable frame 7 through the clamping sleeve 19, and the movable frame 7 is slidably connected to the horizontal axis 4 through the sliding sleeve 21, and is threadedly connected to the threaded part 5 through the screw sleeve 20.
