[0028] The principle of this utility model is as follows: The rated speed is output by the power source servo motor 210 and reducer 220, and the power is driven by the drive wheel 230 and the synchronous belt 240 to rotate the eccentric wheel 250. When the drive wheel 230 rotates, the eccentric wheel 250 revolves around the center of the drive wheel 230, which drives the first connecting rod 260 to swing. The first connecting rod 260 divides the power into two paths, one path is transmitted to the bag lifting linkage mechanism 300, and the other path is transmitted to the bag clamping linkage mechanism 400, thereby realizing the displacement of the bag and the bag clamping linkage mechanism to a specified distance and height position. Then, the power transmitted by the main swing displacement linkage mechanism 200 drives the first adjusting linkage 310, the conversion block 330, and the second adjusting linkage 340 to transmit the power to the first opening and closing swing rod 350. The first opening and closing swing rod 350 is connected to the linkage shaft 360 by bolts. The linkage shaft 360 outputs the input power to the first opening and closing swing rods 350 on both sides, and transmits it to the suction bag side plate 390 through the third adjusting linkage 380. The suction bag side plate 390 swings up and down around the center of the positioning plate. The bag width adjustment plate 3100 is installed on the suction bag side plate 390. The suction rod 3200 and the suction nozzle 3300 are fixed to the bag width adjustment plate 3100 by screws. As the suction bag side plate 390 swings up and down, when the suction nozzle moves down, it sucks up the packaging bag. When it is lifted to the preset angle position, it releases the packaging bag to complete the bag lifting action.

[0029] Finally, the power transmitted by the main swing displacement linkage mechanism 200 drives the main swing rod 290 to reciprocate around the main swing rod support 280. The main swing rod 290 and the linear guide slider assembly 2600 of the left swing rod 2400 are connected. One end of the left swing rod 2400 is connected to the left swing rod bracket 2100 through the swing rod spindle 2300, and the other end is connected to the first swing spindle 410. The first swing spindle 410 is equipped with a bag clamping execution module mechanism. Under the reciprocating swing of the main swing rod 290, the left swing rod 2400 and the right swing rod 2500 are driven to swing around the swing rod spindle 2300 of the left and right swing rod brackets, so that the inner ring hole of the bearing at the center position of the bag clamping execution module is installed on the first swing spindle 410 to follow the movement. The bag clamping actuator module is driven by the cylinder rod end joint bearing assembly 460 pushing the joint connecting rod spindle 4600, which in turn drives the two side joint connecting rods 4500. The middle part of the joint connecting rod 4500 is connected to the little finger connecting rod by a linkage pin and provides rotational support. The other end of the little finger connecting rod is connected to the pin hole of the bag clamping finger side plate 420 by a linkage pin and provides rotational support. The second bag clamping finger 440 is fixed to the joint connecting rod 4500 by screws, and the first bag clamping finger 430 is fixed to the bag clamping finger side plate 420 by screws. The actuator achieves clamping and loosening by opening and closing the first bag clamping finger 430 and the second bag clamping finger 440 through the linkage structure. When clamping the bag, the main swing displacement linkage mechanism 200 drives the bag lifting linkage mechanism 300 to suck up and lift the bag to the set position. Simultaneously, through linkage, it drives the bag clamping execution module in the bag clamping linkage mechanism 400 to swing above the bag lifting linkage mechanism 300, where the cylinder 4800 opens and closes to clamp the packaging bag. At this point, the main swing displacement linkage mechanism 200, the bag lifting linkage mechanism 300, and the bag clamping linkage mechanism 400 are linked together to complete the bag sucking, lifting, and clamping actions. This achieves the process of displacing the packaging bag to the designated position and height according to the movement trajectory of the bag clamping execution module, rotating and uprighting the bag, and then releasing it. This utility model integrates three linkage mechanisms, driven by a single power source, to achieve multi-mechanism linkage, improve bag feeding efficiency, reduce the number of electrical control components and parts, lower manufacturing costs, and provides more stable operation and easier maintenance.

[0030] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
