The rotating plate 303 is fixedly connected to the rotating swing arm 302 and can rotate along with the rotating swing arm 302.
[0034] The rotating cylinder 301 extends and, under the action of the hinge, pushes the rotating swing arm 302 to rotate around the rotating shaft 304, thereby driving the rotating plate 303 to rotate, so that the front end of the rotating plate 303 moves downward around the rotating shaft 304. After rotating to a certain angle, the bag taking assembly 5 clamps the bag, and then the rotating cylinder 301 retracts, driving the rotating plate 303 to reset, thereby completing the bag taking.
[0035] The bag taking assembly 5 includes a bag taking cylinder 501, a front clamping plate 502, and a rear clamping plate 503. The bag taking cylinder 501 is mounted on the rotating plate 303, the front clamping plate 502 is mounted on the driving end of the bag taking cylinder 501, and the rear clamping plate 503 is mounted on the rotating plate 303. The bag taking cylinder 501 moves with the rotating plate 303, clamps the bag at the bottom, and then returns to its original position with the rotating plate 303.
[0036] The bag opening component 4 includes a bag opening cylinder 401, a mounting plate 402, a first suction cup 403, a second suction cup 404, an auxiliary shaft 405, and an auxiliary cylinder 406. The bag opening cylinder 401 is installed in the middle of the rotating shaft 304, and the mounting plate 402 is fixed to the driving end of the bag opening cylinder 401. Two first suction cups 403 are installed on the mounting plate 402. The auxiliary cylinder 406 is fixed to the rotating plate 303, and an auxiliary block 407 is installed on the driving end. The auxiliary shaft 405 is passed through the auxiliary block 407, and the auxiliary shaft 405 is installed with two second suction cups 404.
[0037] There are four suction cups, which respectively suck the bag on both sides and move to both sides under the drive of the bag opening cylinder 401 and the auxiliary cylinder 406 to pull open the bag.
[0038] It also includes a lifting assembly 6, including a lifting cylinder 601, a lifting swing arm, a lifting plate 602, and a baffle 604. The fixed end of the lifting cylinder 601 is hinged to the side plate 203, one end of the lifting swing arm is hinged to the driving end of the lifting cylinder 601, and the other end is connected to the lifting plate 602. The lifting plate 602 and the baffle 604 are connected by a hinge, and the baffle 604 is fixed to the side plate 203.
[0039] The lifting cylinder 601 drives the lifting arm to rotate under the hinged action, so that the lifting plate 602 can support the bag to prevent the bag from sagging and facilitate bag removal. It also cooperates with the stopper 603 to assist in supporting the bag.
[0040] Working principle:
[0041] The moving assembly 1 moves the bottom plate 101 to the bag taking position, and the bag feeding device (not shown) sends the bag to the position of the lifting assembly 6. The lifting plate 602 moves to support the bag, and then the rotating swing arm 302 of the rotating assembly 3 moves to rotate the rotating plate 303 downward, so that the front clamping plate 502 and the rear clamping plate 503 of the bag taking assembly 5 move to the bag position, and then the bag taking cylinder 501 is actuated to allow the front clamping plate 502 and the rear clamping plate 503 to clamp the bag, and then the rotating assembly 3 is reset to keep the bag in a vertical state. At this time, the bag opening assembly The suction cups of component 4 suck the bag on both sides, and the bag opening cylinder 401 and the auxiliary cylinder 406 are activated to pull the bag open. At the same time, the two pulling cylinders 201 of the pulling opening component 2 are activated to move the two side plates 203 relative to each other, so that the bag taking components 5 on both sides are close to each other, and thus the two sides of the bag are close to each other. The bag opening cylinder 401 and the auxiliary cylinder 406 are cooperated to complete the opening of the bag. When the two side plates are pulled towards each other, the rotating shaft 304 and the auxiliary shaft 405 are used to assist, so that the two side plates can be easily moved close to or away from each other.
[0042] After the bag is fully opened, the moving assembly 1 moves to move the bag to the loading position, and then to the sealing position after the loading is completed.
