Figure 1As shown, it includes an inner film releasing frame 1, an inner film hot-melt cutting machine 2, an inner film moving frame 3, an outer bag storage box 4, an outer bag opening mechanism 5 and an inner bag embedding mechanism 6.

[0020] The inner film release rack 1 is used for placing the inner film reel and releasing the inner film. Specifically, the inner film release rack 1 is provided with a pair of rollers 11 to lift the inner film coil core shaft 12. The inner film is released by rotating the inner film reel through the rotation of the motor of the inner film itself or by pulling the inner film through the next process. The rollers are designed in pairs and are arranged on the columns of the inner film release rack through a bearing structure.

The inner film bagging machine according to claim 6 is characterized in that: A crossbeam is arranged on the top of the two columns, the inner bag embedding mechanism (6) is arranged on the crossbeam, and the crossbeam is also provided with the lifting drive, the lifting drive is a hoisting mechanism driven by a servo motor, the hoisting traction rope is connected to the support mouth lifting frame, a slideway is arranged on the column, and sliders are arranged on both sides of the support mouth lifting frame to move and rise on the slideway.

8. The inner film bagging machine according to claim 6, characterized in that: The outer bag mouth support plate is arranged on the support mouth slider, the support mouth slider is on the support mouth slideway, the support mouth slider is arranged on the support mouth lifting frame, a compression spring is arranged between the two support mouth sliders, the two support mouth sliders are respectively connected to the support mouth traction belts, a pair of steering rollers is arranged in the middle of the support mouth lifting frame, the two traction belts pass through the steering rollers and are connected to the front end of the piston rod of the support plate driving cylinder, and the support plate driving cylinder is arranged on the mouth lifting frame.

9. The inner film bagging machine according to claim 6, characterized in that: The crossbeam extends above the outer bag storage box (4) and is provided with the inner bag support opening cylinder (62) installed thereon, the inner bag support opening suction cup (61) on the inner bag support opening cylinder (62) faces the inner film release frame (1), and a suspension is provided on the other side of the crossbeam and is provided with the inner bag pressing cylinder (64) installed thereon.

10. A method for performing inner film bagging according to the inner film bagging machine according to any one of claims 1 to 9, characterized in that: The following steps are included: 1) Release the inner membrane, manually pull the inner membrane to the space between the two conveyors, to the extension section of the inner membrane screen conveyor, and start the conveyor to continuously output the inner membrane; 2) Hot melt cutting: in the extended section of the conveyor, the inner film passes over the inner film support plate, and the inner film hot melt cutting machine (2) first hot melts the inner film and then cuts the hot melt rear end; 3) The inner membrane is moved, and the moving suction cup (21) of the inner membrane moving frame (3) sucks the inner membrane, and then moves to the inner bag embedding mechanism (6) and is placed with the opening facing upward; 4) The outer bag is placed on the outer bag storage box (4), and the outer bag in the outer bag storage box (4) is driven by the friction wheel (42) to leak out of the outer bag storage box (4) at the inclined surface (41). The outer bag opening suction cup (51) contacts the two sides of the outer bag under the drive of the cylinder, and then the two outer bag opening suction cups (51) separate to open the outer bag opening; 5) The outer bag expands, and the two outer bag opening support plates are driven by the lifting drive to descend and penetrate into the outer bag opening. The support plate driving cylinder drives the two outer bag opening support plates to open and fix the outer bag; 6) the inner bag is aligned, the inner bag opening sucker (61) of the inner bag embedding mechanism (6) is extended forward under the drive of the inner bag opening cylinder (62), and together with the movable sucker (21) the inner bag opening is opened, and the inner bag pressing frame (63) is driven by the inner bag pressing cylinder (64) to penetrate into the inner bag opening and the interior of the inner bag; 7) The outer bag rises, the outer bag opening suction cup (51) holds the outer bag opening, and the opening support lifting frame rises under the drive of the lifting drive until the inner bag is embedded in the outer bag opening to the bottom, completing the nesting of the inner bag into the outer bag; 8) Remove the inner and outer bags and repeat steps 1-7) to achieve continuous operation of outer bag and inner film.
