In this embodiment, the bag pulling driving mechanism 13 includes a rotating rod 131, a rotating driver 132 and two transmission belt sets 133, two ends of the rotating rod 131 are respectively rotatably connected to the two seat bodies 111, the rotating driver 132 is used for driving the rotating rod 131 to rotate, the two transmission belt sets 133 are respectively rotatably disposed on the two seat bodies 111, two ends of the rotating rod 131 are respectively in transmission connection with the two transmission belt sets 133, and the moving seats 121 of the two bag clamping mechanisms 12 are respectively connected to the two transmission belt sets 133; specifically, the rotation driver 132 includes a second motor 134 and a second transmission assembly 135, an output shaft of the second motor 134 is drivingly connected to the rotating rod 131 through the second transmission assembly 135, and both the second transmission assembly 135 and the first transmission assembly 15 may adopt a belt transmission structure.

In practical applications, the second motor 134 of the rotation driver 132 drives the rotation rod 131 to rotate via the second transmission assembly 135, the rotation rod 131 drives the two transmission belt sets 133 to rotate respectively, and the rotation transmission belt set 133 drives the moving seat 121 to move reciprocally, so as to realize bag pulling of the bag clamping assembly 122 on the film tube.

In addition, the first screw rod 151 is driven by the first motor 153 to drive the first movable nut 152 and the distance adjusting seat 124 to move, the transmission belt set 133 is driven by the second motor 134 to drive the movable seat 121 to move, the width of the bag can be controlled in a digital mode, the tension during bag pulling can be controlled in a digital mode, automatic adjustment can be achieved, the tension during bag pulling can be controlled in a digital mode, and the sealing effect of the melt-cutting sealing device 7 on the tube film is better.

In this embodiment, the inner wall of the fixed bag clamping plate 125 or/and the inner wall of the movable bag clamping plate 127 are provided with friction stripes 120; through the friction stripes 120, the friction force between the fixed bag clamping plate 125 or/and the movable bag clamping plate 127 and the cylinder film is increased, the stability of bag pulling is improved, and the phenomenon that the cylinder film slips is avoided.

In this embodiment, the moving seat 121 is provided with an adjusting seat 16, the adjusting seat 16 is provided with a height-adjusting groove 161, the height-adjusting groove 161 is vertically arranged, and one end of the guard bar 14 is locked on the height-adjusting groove 161 of the adjusting seat 16 through a locking member. According to the height of the required bottle for protecting and conveying, the locking piece is loosened, so that the guard bar 14 can ascend and descend along the height adjusting groove 161 of the adjusting seat 16 to increase the height of the guard bar 14, and after the height of the guard bar 14 is adjusted, the guard bar 14 is locked on the adjusting seat 16 through the locking piece, so that the stability of the guard bar 14 is ensured; the height of the protective rod 14 is adjustable, which is beneficial to abutting bottles with different heights, so that the bottle protection effect is improved.

Specifically, prop sack device 8 including last sack subassembly 81 and prop sack subassembly 82 down, on prop sack subassembly 81 and prop sack subassembly 82 and set up relatively down, on prop the output of sack subassembly 81 and be connected with and prop pocket plate 83, prop the output of sack subassembly 82 down and be connected with down and prop pocket plate 84, on prop the drive of sack subassembly 81 and prop pocket plate 83 and be close to or keep away from down and prop pocket plate 84 and remove, prop sack subassembly 82 drive down and prop pocket plate 84 and be close to or keep away from on propping pocket plate 83 and remove down. At the beginning, the upper bag supporting plate 83 and the lower bag supporting plate 84 are in a closed state, when the bag pulling device 1 sleeves the bag opening of the tubular film outside the upper bag supporting plate 83 and the lower bag supporting plate 84, the upper bag supporting plate 83 is driven to move upwards by the upper bag supporting assembly 81, the lower bag supporting plate 84 is driven to move downwards by the lower bag supporting assembly 82, the upper bag supporting plate 83 and the lower bag supporting plate 84 move away from each other, the upper bag supporting plate 83 and the lower bag supporting plate 84 are in an opened state until the bag opening of the tubular film is opened by the upper bag supporting plate 83 and the lower bag supporting plate 84, at the moment, the bag pulling device 1 can release clamping and traction on the tubular film, and the bottle pushing mechanism 43 pushes the bottle group into the tubular film.

Specifically, the discharging device 52 adopts a pushing structure to push the product onto the receiving device 51.

The above embodiments are preferred implementations of the present invention, and the present invention can be implemented in other ways without departing from the spirit of the present invention.
