[0026] like Figure 1 As shown, this specific embodiment adopts the following technical scheme: it includes a fixed plate 1, a lower support frame 2, sandpaper 3, a telescope 4, and a single-sided opening mechanism 5; the upper end of the fixed plate 1 is installed with a lower support frame 2, the lower support frame 2 can support the bag body, the upper end surface of the lower support frame 2 is installed with sandpaper 3, the sandpaper 3 can prevent the bag body from slipping, and facilitate the opening of the upper part of the bag body, telescopes 4 are installed on both sides of the upper end surface of the fixed plate 1, and the upper end of the rod body of the telescope 4 is installed with a single-sided opening mechanism 5, the telescope 4 can drive the single-sided opening mechanism 5 to descend, and the upper part of the bag body is opened by the single-sided opening mechanism 5, as shown in FIG. Figure 2 As shown, the upper end surface of the lower support frame 2 is an inclined surface body 2-1, and the inclined surface body 2-1 can open the upper part of the bag body along the inclined surface body 2-1 when the single-sided opening mechanism 5 descends.

[0027] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, in this specific embodiment, the bag body is opened by a single-sided opening mechanism, and the following technical scheme is specifically adopted: the single-sided opening mechanism 5 includes a mounting frame 5-1, an opening plate body 5-2, a rotating shaft 5-3, a rotating frame 5-4, a mounting strip 5-5, a rubber strip 5-6, and a reset mechanism 5-7; a plurality of rotating sleeves are installed on the front side wall of the mounting frame 5-1, the rotating shafts 5-3 are respectively connected to the rotating frames 5-4 and installed in the rotating sleeves, the rotating frame 5-4 is installed at the upper end of the opening plate body 5-2, and the opening plate body 5-2 can rotate by relying on the rotating shaft 5-3, so that the opening plate body 5-2 can descend along the inclined surface. A mounting groove 5-21 is opened at the lower end of the opening plate body 5-2, and a mounting strip 5-5 is installed in the mounting groove. A rubber strip 5-6 is installed at the bottom of the mounting strip 5-5, and the rubber strip 5-6 can contact the upper end surface of the bag body. A reset mechanism 5-7 is installed on the mounting frame 5-1. The reset mechanism 5-7 automatically resets when the opening plate body 5-2 moves up, and the reset mechanism 5-7 is connected to the opening plate body 5-2. The reset mechanism 5-7 includes a screw rod 5-71, a gasket 5-72, a reset spring 5-73, and an adjusting nut 5-74; one end of the screw rod 5-71 is connected to the front side wall of the mounting frame 5-1, the screw rod 5-71 is passed through the opening plate body 5-2, the gasket 5-72 and the reset spring 5-73 are sleeved on the screw rod 5-71, and the adjusting nut 5-74 is installed on the front side of the screw rod 5-71, and the compression amount of the reset spring 5-73 is adjusted by adjusting the nut 5-74.

When it is conveyed to the opened cutting line, the telescopic device 4 is started, and the telescopic device 4 drives the single-sided opening mechanism 5 to descend. At this time, the rubber strip 5-6 at the lower end of the opening plate 5-2 contacts the upper end surface of the bag body, so that the bag body is between the sandpaper 3 and the rubber strip 5-6. At this time, the sandpaper 3 and the rubber strip 5-6 can ensure that the bag body is pressed tightly, and the bag body remains motionless under the friction force of the sandpaper 3, and the rubber strip 5-6 will descend according to the inclined surface of the inclined surface body 2-1 under the action of the inclined surface body 2-1 of the lower support frame 2.
