Described in Fig. 8, when material bag 14 sacks are opened process, flap assembly 5 all rests on the upper end of sack. At this moment, the door 5-1 on the door door assembly 5 stretches out and drives the doors 5-1 on the door door assembly 5 to close together.

And the bag clip assembly 6 bag clip cylinder swivel seat 6-4 shrinks and the bag clip seat 6-2 is opened.

Described in Fig. 6, after material bag 14 sack openings were fully opened, the door lifting cylinder 5-15 on the door assembly 5 stretched out, and two doors 5-10 were inserted into material bag 14 li.

As shown in Figure 10, when the flap assembly 5 penetrates into the material bag 14, the flap cylinder 5-1 on both sides shrinks and drives the door 5-10 to open to both sides, while the bag clip cylinder 6-1 on the clip bag assembly 6 Reach out to clip both sides of the bag to doors 5-10. At this time, the receiving work can be carried out.

As shown in Figure 1, the gripper 1 is connected to the rotating shaft 1-6 through the jaw cylinder 1-2 and the cylinder base 1-5, and the rotating shaft 1-6 is connected to the fixed shaft 1-7 through the nylon bushing 1-8, and fixed The two ends of the shafts 1-7 are fixed on the front panel 7 and the rear panel 8 respectively. The connecting plate 1-4 is connected with the rotating shaft 1-6. The two grippers 1 realize the necking action through the two necking connecting rods 4-10 and the necking assembly 4 on the connecting plate 1-4 and the necking assembly 4. In the necking assembly 4, the necking cylinder 4-1 is connected with the front panel 7 with the connecting seat 4-5.

The flap door shrinking device among the present invention realizes assembly forming by the frame that an upper cover plate 9, two reinforcing plates 12, a rear panel 8, a front panel 7 and two laths 10,11 form. This frame can also be realized by welding, casting, and whole plate machining.

The bag-opening method of the material bag 14 among the present invention adopts the bag-opening suction cup 15, and the working principle of the well-known suction cup is exactly that the suction cup forms a vacuum between the objects to be adsorbed, and the objects are tightly adsorbed on the suction cups. However, only when the material of the adsorbed object (the material bag in the present invention) is relatively sealed can it work stably and reliably. However, the flap and necking device in the present invention not only faces these better-sealed packaging bags, but also can replace the bag-opening suction cup with a specially designed woven bag with poor air-tightness to clamp, open and fill the bag. Therefore the bad woven bag of airtightness is also the protection domain of the present invention to clamp the flap door shrinking device that bag opening filling is used.

Based on the technical characteristics described in the present invention, the lifting of the door assembly 5 is realized by the door lifting cylinder 5-15 and the linear guide rail (the combination of the slide block 5-5 and the guide rail 5-6 described in the present invention). . However, through the enlightenment of the present invention, those skilled in the art can also use motors (not limited to ordinary motors, servo motors, stepping motors, etc.) and gears to realize this function, which is within the protection scope of the present invention.

Based on the pneumatic technical features described in the present invention, all transmission power sources come from "air cylinders", whose kinetic energy is all pressurized gas. However, through the enlightenment of the present invention, those skilled in the art can also use hydraulic or electric forms to realize the transmission function by changing the power source, which is within the protection scope of the present invention.
