The working principle of the swing mechanism is as follows: in an initial state, the tension spring drives the first swing arm 651 to be away from the feeding hole 611, so that the first swing arm 651 and the second swing arm 652 are in a state of being away from each other, namely, the first swing arm 651 and the second swing arm 652 are in an open state when being transversely opened, the transverse opening mechanism keeps the open state under the action of the tension spring, and therefore the first rotary disc 610 can keep the open bag to prevent the bag from falling off when rotating; when the opening and transferring mechanism transfers the vertically opened sleeve bag to the transverse opening mechanism, the connecting rod driving device 640 pushes the second connecting rod 662, the second connecting rod 662 drives the first swing arm 651 and the second swing arm 652 to swing inwards through the first connecting rod 661 so as to extend into the interior of the sleeve bag, after the first swing arm 651 and the second swing arm 652 extend into the interior of the sleeve bag, the second suction cup 530 of the opening and transferring mechanism is released, the connecting rod driving device 640 resets, the first swing arm 651 and the second swing arm 652 expand outwards under the action of the tension spring to support and open the sleeve bag, then the first rotary driving device 630 drives the first rotary disc 610 to rotate, so that the feeding hole 611 at the transverse opening mechanism with the sleeve bag is aligned with the second transverse moving device 620, then the second transverse moving device 620 drives the pushing block to move forwards, the external content is pushed into the sleeve bag and the discussion point is pushed away from the transverse opening mechanism. The swinging mechanism is in an opening state under the condition of no loading of a driving device, so that the transverse opening mechanism can conveniently transfer the sleeve bag in the opening state, and in addition, the connecting rod driving device 640 is fixed on the rack 100 instead of the first rotating disk 610, so that the whole structure arrangement is simpler and more reasonable. And because two transverse opening mechanisms are arranged, when the transverse opening mechanism positioned at the lower side is used for feeding, the transverse opening mechanism positioned at the upper side is used for receiving and opening the sleeve bag adsorbed by the conveying mechanism, so that the time for returning the transverse opening mechanism of the lamp strip is saved, and the production beat is improved.
