Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging technology, and in particular to a packaging bag support device. Background Technology
[0002] In automated packaging production lines, bag support plates are needed to hold up the bag opening and transfer the bag. The existing technology has the problem that conventional bag support plates are too small, resulting in insufficient supporting pressure. This causes the bag to detach from the support plate during transfer, or the support plate, when aligned with the bag opening, cannot fully open the bag. A common solution is to simply enlarge the shape of the support plate, but this results in the support plate directly puncturing the bag. Insufficient supporting pressure causes the bag to separate from the support plate, while excessive pressure causes it to puncture the bag. Therefore, a suitable solution to the bag support problem is needed, and a packaging bag support device has been designed for this purpose. Utility Model Content

The bag support plate 4 includes a fixed end 401, a lever arm section 402, and a bag support end 403. The surface of the bag support end 403 is provided with an assembly groove 404. A positioning plate 405 is fixed inside the assembly groove 404. A lower moving rod 406 and an upper moving rod 407 are respectively movably mounted on the upper and lower surfaces of the positioning plate 405. An upper contact plate 408 is threadedly fixed to the top of the lower moving rod 406. A first spring 409 is mounted on the surface of the lower moving rod 406 between the upper contact plate 408 and the positioning plate 405. A lower contact plate 410 is threadedly fixed to the bottom of the upper moving rod 407. A second spring 411 is mounted on the surface of the upper moving rod 407 between the lower contact plate 410 and the positioning plate 405.
[0019] The mounting plate 1 has an assembly plate fixed to its side wall for movably mounting the bidirectional reciprocating lead screw 2. The mounting plate 1 has a drive motor 6 fixed to its side wall and on one side of the assembly plate. The output end of the drive motor 6 is fixed to one end of the bidirectional reciprocating lead screw 2.
[0020] The side wall of the mounting plate 1 is fixed with a bracket for fixing the drive motor 6.
[0021] The deflection mechanism 5 includes a side frame 501 and a fixed plate 502 fixed to the surface of the mounting plate 1. A telescopic cylinder 503 is fixed to the side wall of the side frame 501. A connecting piece 504 is threadedly fixed to the bottom moving end of the telescopic cylinder 503. A transmission rod 505 is fixed through the side wall of the fixed plate 502. A deflection plate 506 is fixed to one end of the transmission rod 505. The other end of the transmission rod 505 is movably installed with the side frame 501. A movable groove 507 is opened on the surface of the deflection plate 506. A movable piece 508 is movably installed inside the movable groove 507. The movable piece 508 is inserted into the side wall of the connecting piece 504.
[0022] The connector 504 has a threaded connection hole at the top and an insertion through hole on the side wall.
[0023] The side wall of the side frame 501 is fixed with multiple positioning parts for fixing the telescopic cylinder 503.
[0024] After this packaging bag-holding device is installed into the production line, it is also necessary to install a control terminal in conjunction with the production line so that the electrical equipment in this device can work periodically in coordination with other equipment on the production line.
[0025] When this device is in use, the control terminal sends signals to the telescopic cylinder 503 and the drive motor 6, causing the telescopic cylinder 503 and the drive motor 6 to operate. When the telescopic cylinder 503 operates, its moving end moves up and down. The telescopic cylinder 503, the connecting part 504, and the moving part 508 are a single moving structure. The movement of the moving end of the telescopic cylinder 503 can drive the moving part 508 to move up and down. Since the moving part 508 is movably installed in the movable groove 507 of the deflection plate 506, the up and down movement of the moving part 508 drives the deflection plate 506 to move up and down. 06. Deflection is initiated because the deflection plate 506, transmission rod 505, fixed plate 502, mounting plate 1, and the bag-supporting plate 4 mounted on the side wall of mounting plate 1 form an integrated moving structure. Furthermore, because the transmission rod 505 is movably mounted on the side wall of the side frame 501, when the deflection plate 506 initiates deflection, the mounting plate 1 and the surface mounting structure deflect together around the centerline of the transmission rod 505, ultimately causing the bag-supporting plate 4 to deflect and insert itself into the bag that needs to be opened. When the drive motor 6 operates, the output end of the drive motor 6 carries... The bidirectional reciprocating screw 2 rotates, and the screw nuts 3, which are symmetrically threaded on the surface of the bidirectional reciprocating screw 2, move synchronously in opposite directions. When the screw nuts 3 on both sides move synchronously, they drive the bag-supporting plates 4 on both sides to move synchronously in opposite directions, thus opening the bag opening. During the opening process, the upper contact plate 408 and the lower contact plate 410 of the bag-supporting plate 4 contact the inner surface of the bag. As the distance between the two bag-supporting plates 4 increases, the contact pressure between the upper contact plate 408, the lower contact plate 410 and the inner surface of the bag increases, and the downward moving rod 406 moves downward, while the upward moving rod 406 moves upward. As rod 407 moves upward, the first spring 409 and the second spring 411 contract. When the bag-supporting plate 4 stops moving, the first spring 409 and the second spring 411 provide pressure to the inside of the bag, improving the bag's opening and positioning effect and preventing the bag from detaching from the bag-supporting plate 4 during transfer. On the other hand, when the bag-supporting pressure is too high, since the upper contact plate 408 and the lower contact plate 410 can move up and down, the first spring 409 and the second spring 411 absorb energy, which can absorb some of the pressure and reduce the risk of bag breakage.
