Detailed Description

The present invention is described in detail with reference to the embodiments shown in the drawings, but it should be understood that these embodiments are not intended to limit the present invention, and those skilled in the art should understand that the functions, methods, or structural equivalents or substitutions made by these embodiments are within the scope of the present invention.

A lower opening device as shown in fig. 1-3 comprises a first cylinder 1, a panel 3 connected to a piston rod 11 of the first cylinder 1, a second cylinder 2 connected to the panel 3, and a suction cup 5 connected to a piston rod 21 of the second cylinder 2. In this embodiment, the number of the suction cups 5 is two.

The panel 3 comprises a horizontal plate 31 and a vertical plate 32 which are connected, and two ends of the horizontal plate 31 and the vertical plate 32 are enclosed with side plates 33. The panel 3 is provided with a through hole 310 for the suction cup 5 to go up and down. The through hole 310 is opened in the horizontal plate 31.

A piston rod 11 of the first cylinder 1 is connected with a first connecting block 12. One of the side plates 33 is connected to a bottom plate 34, and the bottom plate 34 is connected to the first connecting block 12. The piston rod 11 of the first cylinder 1 extends to drive the panel 3 to ascend, and the piston rod 11 of the first cylinder 1 retracts to drive the panel 3 to descend.

Still include sucking disc support 4, sucking disc 5 is connected on sucking disc support 4. An air pipe 41 is connected to the suction cup holder 4, and the air pipe 41 is connected to a blower (not shown). The blower works to suck the air in the sucker 5 out through the sucker support 4 and the air pipe 41 in sequence, so that the sucker 5 generates negative pressure to suck the bag surface.

The cylinder body of the second cylinder 2 is connected to the vertical plate 32, and the second cylinder 2 and the panel 3 are lifted synchronously. The piston rod 21 of the second cylinder 2 is connected with a second connecting block 22, the sucker support 4 is connected with a supporting plate 221, and the supporting plate 221 is connected with the second connecting block 22. The piston rod 21 of the second cylinder 2 is extended to drive the suction cup 5 to rise in the through hole 310 to protrude out of the horizontal plate 31.

The working principle of the lower opening device is as follows: the piston rod 11 of the first cylinder 1 extends to drive the panel 3 to ascend synchronously, the bag is conveyed to the horizontal plate 31 and is positioned right above the through hole 310, the bag feeding surface is sucked by the upper sucking disc (not shown), the piston rod 21 of the second cylinder 2 extends to drive the sucking disc 5 to ascend in the through hole 310 to the protruding horizontal plate 31, the sucking disc 5 abuts against the lower bag surface of the bag, the air blower works, the air in the sucking disc 5 sequentially passes through the sucking disc support 4 and the air pipe 41 to be sucked out, the sucking disc 5 generates negative pressure to firmly suck the lower bag surface, the piston rod 11 of the first cylinder 1 retracts to drive the panel 3 to descend synchronously, the sucking disc 5 descends synchronously, the bag surface is pulled downwards to enable the bag to form a lower opening quickly, loading is facilitated, and packaging efficiency is improved.
