Move right, and then the left and right movement of the rear suction cup cylinder 47 can drive the rear suction cup 49 to approach or move away from the material bag in the vibration box. It should be noted that the position of the rear suction cup mechanism is on the same horizontal plane as when the adsorption component of the upper bag mechanism is flipped to the horizontal direction, that is, the two rear suction cups on the rear suction cup mechanism and the two suction cups on the adsorption component overlap one by one. Through the cooperation between the two, when they are close to each other, they can be tightly sucked on both sides of the opening end of the material bag. When the two move away from each other, the opening of the material bag adsorbed with them can be enlarged, thereby facilitating the discharge barrel to extend into the material bag for discharging.

[0031] See also Figure 7 and Figure 8 The lifting funnel device 5 includes a discharge barrel 60, a lifting mechanism, a bag holding arm 63, a vacuum nozzle 67 and a suction lifting mechanism.

[0032] See also Fig. 9 and Fig.10 , the quantitative discharging device 7 is installed on the top of the frame 1, including a weighing component and a feeding component. The feeding component includes a feeding barrel 74, a feeding barrel mounting frame 77 and a spiral conveying barrel 78.

One end of the outer side of the spiral conveying barrel 78 is connected to the motor d73, and the other open end is located above the open end of the weighing hopper 72. A dragon is arranged in the spiral conveying barrel 78. When the material enters the spiral conveying barrel 78 from the feeding barrel 74, the dragon is controlled to rotate by turning on the motor d73 to transport the material into the weighing hopper 72; the weighing component is installed below the discharge port of the spiral conveying barrel 78, including the weighing hopper mounting frame 77.

The weighing sensors 76 are used to control the weight of the material in the weighing hopper 72, and a pneumatic valve 71 is connected between the bottom end of the weighing hopper 72 and the discharge port flange 70 for use with the weighing sensor. When the material discharged into the weighing hopper reaches the set weight, the pneumatic valve 71 is opened. When the pneumatic valve 71 is opened, the material falls from the weighing hopper 72 through the discharge cylinder to the material bag. When the pneumatic valve 72 is closed, the weighing hopper stops discharging the material.

[0033] When the present invention is working, the front plate of the vibration box body is first opened, and the material bag on the material plate is adsorbed by controlling the suction cup 36 of the bag-loading mechanism, and then the material bag is driven to move in the direction close to the vibration box through the transmission component. When the material bag reaches the front of the vibration box body, the flip cylinder of the bag-loading mechanism is controlled, and the adsorption component is driven to flip through the slide rail, so that the adsorbed material bag rotates counterclockwise and stands up and is placed in the opened box body. Then the front plate of the vibration box body is closed. When the material bag is placed in the box body, the rear suction cup in the rear suction cup mechanism is controlled to move in the direction close to the material bag. , so that the two rear suction cups on the rear suction cup mechanism and the two suction cups on the adsorption assembly overlap one by one, and are tightly adsorbed to the two sides of the bag respectively, and then the two suction cups are controlled to move away from each other, so that the opening of the bag adsorbed thereto is enlarged, and then the lifting mechanism in the lifting funnel device is controlled to drive the discharge barrel to move downward and extend into the bag, and then the main controller controls the bag clamping cylinder to adjust the distance between the two bag clamping arms, and the bag is tightly clamped at the discharge end at the bottom of the discharge barrel. At the same time, the spiral conveyor barrel in the quantitative discharge device starts The material is discharged into the weighing hopper. When the weighing sensor senses that the weight of the material in the weighing hopper reaches the set value, the spiral conveyor stops discharging the material downwards, and the pneumatic valve at the bottom of the weighing hopper opens. The material in the weighing hopper falls downwards into the material bag through the discharge cylinder. When all the material in the weighing hopper falls into the material bag, the pneumatic valve is closed and a certain weight of material is discharged into the weighing hopper again through the spiral conveyor. In addition, when the material falls into the hopper, the vibrator on one side of the box body is turned on to shake the material bag in the box body during the material discharge process, so that the material When the material bag is full of materials, the two bag clamping arms are separated from the clamping of the bag on the discharge barrel by the bag clamping cylinder, and the lifting mechanism in the lifting funnel device is controlled to drive the discharge barrel to move upward to be pulled out of the bag, and finally the heating plate of the sealing mechanism is driven to seal the bag. After sealing, the front plate of the vibration box is opened to make the bag full of materials fall down with the front plate. In this way, the material loading of one bag can be completed through the above working process, and each bag on the bag holding plate can be loaded by repeating the above steps. Example

[0034] The similarities between this embodiment and the first embodiment are not repeated here. The difference is: Figure 4 The material holding plate 38 is fixedly mounted on one side of the middle part of the mounting frame 30 and is fixedly connected to a driving motor fixed on the bottom surface of the mounting frame 30. The driving motor is used to control the up and down movement of the material holding plate, so that not only more empty material bags can be placed on the material holding plate, but also the suction cup assembly above the material bag can be cooperated with to prevent the suction cup from falling off easily when adsorbing the empty material bag, thereby further improving the work efficiency. Example

[0035] The similarities between this embodiment and the first embodiment are not repeated here. The difference is: Fig. 9 and Fig.10 A sealing cover is installed at the discharge port of the spiral conveying cylinder 78. The hinged end of the sealing cover is fixed to the output end of the cylinder. The opening and closing of the sealing cover is controlled by the cylinder. After the spiral conveying cylinder 78 completes the material conveying into the weighing hopper 72, the main controller controls the cylinder to drive the sealing cover to seal the feeding end of the spiral conveying cylinder. This can further control the weight of the material conveyed to the weighing hopper and avoid too much material falling from the spiral conveying cylinder into the weighing hopper, which requires manual adjustment and affects work efficiency.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the present invention.
