Reference Figure 4 、 Figure 2 When driving, the driving motor 302 operates under the action of an external power supply and controller, driving the driving wheel to rotate, and the driving wheel drives the driving belt 303 to move, thereby driving the driving seat 305 to rise or fall.

The opening member 7 is opened under the action of the air flow sent by the air supply member 8; Reference Figure 7 , Figure 6 , during the opening operation, the telescopic member drives the arc-shaped frame 604 to rotate around the support arm 607 as the center, thereby driving the mounting block 608 to move downward to the valve opening of the valve bag. The opening member 7 can be inserted into the valve opening and, under the action of the air flow, expand the valve opening to provide a necessary opening for subsequent bag feeding and filling; the blocking claw 609 is used to block the valve bag to ensure the stability of the opening of the valve opening of the valve bag; the end of the blocking claw 609 away from the mounting block 608 is arc-shaped to ensure that the blocking claw 609 will not cut the valve bag and avoid movement interference between the blocking claw 609 and the valve bag.

[0024] The telescopic member includes a mounting seat 602 and a support seat 605 fixedly installed on the stabilizing assembly 4. A telescopic device 601 is rotatably connected to the mounting seat 602. The telescopic end of the telescopic device 601 is fixedly connected with a connecting seat 603. The support seat 605 is rotatably matched with the support arm 607, and the connecting seat 603 is rotatably matched with the driving arm 606; Reference Figure 6 , Figure 7 , during the telescopic operation, the telescopic device 601 can be any one of a telescopic cylinder and an electric push rod, and can drive the connecting seat 603 to extend or retract, so as to drive the arc-shaped frame 604 to rotate through the driving arm 606.

[0025] The air supply member 8 includes an insertion tube 801 fixedly installed on the mounting block 608. The inner end of the insertion tube 801 is fixedly connected with an air outlet tube 802. The outer end of the insertion tube 801 is fixedly installed with an air inlet valve 803. An air inlet pipe 804 is fixedly connected to the air inlet valve 803. The air inlet pipe 804 is communicated with an external air source; Reference Figure 7 , Figure 9 , during the air supply operation, the external air source enters the insertion tube 801 through the air inlet pipe 804 and the air inlet valve 803, and then blows out from the opening of the air outlet tube 802; the air inlet valve 803 can be an electromagnetic valve for controlling the entry of gas.

[0026] The opening member 7 includes a slide rail 6081 fixedly installed on the side of the mounting block 608 close to the valve pocket. A slider 703 is slidably connected to the slide rail 6081. A return spring 6082 is fixedly connected between the slider 703 and the mounting block 608. An opening claw 701 is fixedly connected to the slider 703. An adaptation groove 7014 is provided at one end of the opening claw 701 close to the slider 703. The adaptation groove 7014 is adapted to the insertion tube 801. An air inlet hole 7013 is provided in the adaptation groove 7014. A cavity 7011 is provided in the opening claw 701. An air outlet hole 7012 is provided on the outer side wall of the opening claw 701. A baffle 702 is rotatably connected to the opening claw 701 at one end close to the slider 703 through a rotating part 704. The baffle 702 is in close contact with the opening claw 701 in the non-force state, and the baffle 702 covers and blocks the air outlet hole 7012; Reference Figure 8 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , during the opening operation, when the external air flow blows out from the opening of the outlet pipe 802, the air flow directly acts on the inner wall of the adaptation groove 7014. The thrust generated by the air flow will first push the whole opening claw 701 and the slider 703 to overcome the elastic force of the return spring 6082 and slide on the slide rail 6081 along the length direction of the outlet pipe 802, realizing the function of initially opening the valve port; the existence of the baffle 702 will increase the diameter of the thicker position of the opening claw 701 and also improve the opening degree of the opening claw 701; Due to the existence of the air inlet hole 7013, the air flow in the adaptation groove 7014 will enter the cavity 7011 from the air inlet hole 7013. The baffle 702 covers the air outlet hole 7012 due to the elastic force of its own material. It takes a certain time for the cavity 7011 to be filled with gas. When the whole opening claw 701 and the slider 703 move to the limit position, due to the continuous inflow of gas, the air pressure in the cavity 7011 will increase. The high-pressure air flow will push the baffle 702 to rotate around the rotating part 704. The baffle 702 is in the open state, further opening the valve port to ensure that the valve port is fully opened; The slider 703 is symmetrically arranged, which can reduce the friction of the whole movement of the opening claw 701 and the slider 703; the return spring 6082 can generate elastic force after being compressed, and the elastic force can be used to push the slider 703 and the opening claw 701 to reset, facilitating the next opening operation; the opening claw 701 can be made of plastic material, with a small overall weight, and the gas can easily blow it away; since one end of the opening claw 701 is in a pointed state, when the opening claw 701 rotates on the arc-shaped frame 604, it will insert into the valve port of the valve pocket to initially expand the valve port; While the arc-shaped frame 604 is reset, the friction between the baffle 702 and the valve bag can be used to further expand the lower part of the valve opening of the valve bag, making the valve opening more suitable for the filling pipe nozzle. Due to the elastic force of its own material, when the baffle 702 is not blown by the air flow, the baffle 702 will reattach to the outer wall of the opening claw 701. For example, the material of the baffle 702 can be made of rubber material. According to the actual opening state of the valve opening, multiple baffles 702 can be provided. For example, two, four, six. Multiple baffles 702 correspond to multiple air outlet holes 7012, ensuring that each air outlet hole 7012 can blow up one baffle 702, so as to increase the contact points between the baffle 702 and the inner wall of the valve opening of the valve bag, making the valve opening more thoroughly expanded. Sealing rings can be added to the inner side wall of the matching groove 7014 and the root position of the air outlet pipe 802, so that the air flow can only enter the air inlet hole 7013, and the air flow will not be discharged from the matching groove 7014, improving the utilization rate of the air flow. Since the air outlet end of the air outlet pipe 802 is designed with a tip, most of the air flow can be blocked by the air outlet pipe 802 itself, and the air flow can enter the air inlet hole 7013.

[0027] There are two opening claws 701, and the overall shape formed by the two opening claws 701 is conical, and the longitudinal section shape of the baffle 702 is circular ring-shaped. Reference Figure 10 , one end of the opening claw 701 is a tip, so it is easier to insert into the valve opening of the valve bag.

[0028] Working principle: During the bag loading operation, the lifting motor 202 works under the action of the power supply and the controller, driving one of the driving wheels to rotate, and the driving wheel drives the lifting belt 203 to move, thereby driving the lifting seat 205 to descend. Then the driving motor 302 works under the action of the peripheral power supply and the controller, driving the driving wheel to rotate, and the driving wheel drives the driving belt 303 to move, thereby driving the driving seat 305 to descend, so that the suction cup group 5 contacts the valve bag, and the valve bag is adsorbed by the negative pressure adsorption force of the suction cup group 5. Then the lifting motor 202 and the driving motor 302 rotate. During the process of the valve bag moving vertically upward, the telescopic component drives the arc-shaped frame 604 to rotate away from the telescopic device 601 with the connection point between the support arm 607 and the support seat 605 as the center, thereby driving the mounting block 608 to move downward to the valve opening of the valve bag. The opening claws 701 in the opening member 7 can be inserted into the valve opening to perform a preliminary expansion of the valve opening. During the opening operation, when the external air flow blows out from the opening of the air outlet pipe 802, the air flow directly acts on the inner wall of the fitting groove 7014. The thrust generated by the air flow will first push the opening claw 701 and the slider 703 as a whole to overcome the elastic force of the return spring 6082 and slide on the slide rail 6081 along the length direction of the air outlet pipe 802, realizing the function of initially opening the valve port. Due to the existence of the air inlet hole 7013, the air flow in the fitting groove 7014 will enter the cavity 7011 through the air inlet hole 7013. The baffle 702 covers the air outlet hole 7012 due to the elastic force of its own material. It takes a certain amount of time for the cavity 7011 to be filled with gas. When the opening claw 701 and the slider 703 move as a whole to the extreme position, due to the continuous inflow of gas, the air pressure in the cavity 7011 will increase. The high-pressure air flow will push the baffle 702 to rotate around the rotating part 704. The baffle 702 is in the open state, further opening the valve port to ensure that the valve port is fully opened. Then, during the reset action of the arc-shaped frame 604, by using the friction force between the baffle 702 and the valve pocket, the lower part of the valve port of the valve pocket can be further expanded, making the valve port more suitable for the filling pipe opening. Then the air outlet pipe 802 stops supplying air. Due to the elastic force of its own material, the baffle 702 will reattach to the outer wall of the opening claw 701, thus meeting the requirements for the next opening operation.
