Description

Technical Field

[0001] This utility model relates to packaging equipment, specifically to a double-row bagging device. Background Technology

[0002] A bagging machine is a device used to automatically fill materials into packaging bags. The working principle of a bagging machine is to unwind the packaging bag using an unwinding frame, cut the bag into individual pieces, and then transport the bags to the opening station via a conveyor belt for opening and filling. Traditional bagging machines use a single linear structure, meaning one machine can only bag one bag at a time. Increasing efficiency requires adding another production line, resulting in high production costs. Furthermore, the opening and filling structure of traditional bagging machines is relatively complex, making assembly cumbersome and reducing filling efficiency. Utility Model Content

[0016] As shown in the figure, this utility model discloses a double-row bagging device, including a first unwinding shaft 1 and a second unwinding shaft 2 arranged side by side. A traction component 3, a cutting component 4, and a bag-feeding conveyor belt 7 are sequentially arranged on one side of the first and second unwinding shafts. The traction component 3 and the cutting component 4 are common structures on the market and will not be described in detail. Depending on the application, a sealing component can also be set before the traction component to seal the packaging bag. Bag-opening and filling components are arranged on both sides of the conveying path of the bag-feeding conveyor belt 7. The bag-opening and filling components include a lifting seat 10, and the lifting seat 10 and the lifting drive... The lifting platform 10 is equipped with a bag-opening suction nozzle 11, a bag-supporting component is provided below the lifting platform, a feeding platform 5 is provided on the rear side of the lifting platform 10, a feeding push rod 6 is provided on the feeding platform 5, a clearance groove 23 is provided on the feeding platform 5 for the feeding push rod 6 to pass through, the feeding push rod 6 is connected to the drive chain, a movable seat 21 is provided above the discharge end of the feeding platform 5, the movable seat 21 is connected to the movable drive component, a first rotating shaft 18 is provided on the movable seat 21, the first rotating shaft 18 is connected to the rotation drive component, and a pusher arm 13 is provided on the first rotating shaft 18.

[0017] Furthermore, the bag conveyor belt 7 is equipped with adsorption holes 8, and a negative pressure component is provided corresponding to the adsorption holes. The negative pressure component can be a negative pressure seat located below the bag conveyor belt 7. The top of the negative pressure seat has a negative pressure groove corresponding to the adsorption hole 8. The negative pressure groove is connected to the negative pressure chamber inside the negative pressure seat. The negative pressure chamber is connected to a negative pressure machine. By controlling the negative pressure machine, a negative pressure is generated in the negative pressure chamber and the negative pressure groove, which in turn generates a negative pressure at the adsorption hole 8, thereby adsorbing the bag body, improving the stability of the bag conveyor belt, and ensuring that the bag body at the bottom can be firmly adsorbed on the bag conveyor belt 7 when opening the bag, thus ensuring the smooth progress of the bag opening operation.

[0018] Furthermore, the lifting drive assembly includes a first cylinder 9, the piston rod of which is connected to the lifting seat 10. By controlling the first cylinder 9, the lifting seat 10 and the bag-opening nozzle 11 can be raised and lowered.

[0019] Furthermore, the moving drive assembly includes a linear motor 22, the slider of which is connected to the moving base 21. The rotating drive assembly includes a second cylinder 20, the piston rod of which is hinged to one end of the first transmission arm 19, and the other end of the first transmission arm 19 is connected to the first rotating shaft 18. With the above structure, the pusher arm 13 can be moved horizontally by controlling the linear motor 22, and the pusher arm 13 can be swung up and down by controlling the action of the second cylinder 20 and the transmission of the first transmission arm 19.

[0020] Furthermore, the bag-supporting assembly includes left and right bag-supporting arms 12. One end of each bag-supporting arm 12 is connected to a corresponding second rotating shaft 14, which is mounted on a movable frame 17. The movable frame 17 can be connected to a corresponding cylinder to drive it to move back and forth. One end of the second rotating shaft 14 is connected to a second transmission arm 15, and the other end of the second transmission arm 15 is connected to the piston rod of a third cylinder 16. By controlling the movement of the movable frame 17, the bag-supporting arms 12 can be moved. By controlling the movement of the third cylinder 16 and transmitting the force through the second transmission arm 15 and the second rotating shaft 14, the bag-supporting arms 12 can be oscillated.

[0021] The working principle of this utility model is as follows: The first set of packaging bag substrates is unwound through the first unwinding shaft 1, and the second set of packaging bag substrates is unwound through the second unwinding shaft 2. The two sets of packaging bag substrates are pulled to the cutting component 4 for cutting into two independent packaging bags, which are then conveyed side by side by the bag feeding conveyor belt 7. When the two packaging bags are respectively delivered to the corresponding bag opening and filling components, the lifting seat 10 drives the bag opening suction nozzle 11 to descend, so that the bag opening suction nozzle can suck up the upper part of the opening end of the packaging bag. Then the bag opening suction nozzle 11 rises to open the bag mouth. Subsequently, the moving frame is controlled to drive the bag supporting arm 12 to move and extend into the opened bag. Then, control the third cylinder 16 to move, causing the bag-supporting arm 12 to swing open the bag. At this time, the material to be bagged is placed on the feeding platform 5 and pushed to the opening of the packaging bag by the feeding push rod 6. Then, control the moving seat 21 to move, causing the pushing arm 13 to move. At the same time, control the second cylinder 20 to move, causing the pushing arm 13 to swing down, so that the pushing arm 13 can push the material on the feeding platform 5 into the packaging bag, thereby realizing the bag opening and filling operation. After that, the pushing arm 13 and the bag-supporting arm 12 are reset, the bag opening suction nozzle 11 releases the packaging bag, and the bag conveyor belt can carry the filled packaging bag backward to the next station.
