[0004] The applicant discovered the following problems when using the aforementioned bagging device:

[0005] First, the bag conveyor line, bag opening assembly, and bag support assembly are located on the same straight line in the front-to-back direction. The bag conveyor line is used to input empty bags and output filled bags, which greatly affects the processing speed and leads to slow processing speed.

[0006] Secondly, the prior art adopts a method in which the bag opening assembly is stationary while the bag supporting assembly moves forward and backward. In actual production, for different packaging bags, the bag supporting assembly (the size of the rectangular frame formed) needs to be adjusted, while for the bag opening assembly, only the stroke of the movable adsorption mechanism needs to be adjusted (or no adjustment may be required). If the bag supporting assembly needs to be designed as an adjustable structure, it will be heavy and complex in structure, which is not conducive to forward and backward movement. Utility Model Content

The bag support assembly 3, the bag opening assembly 2, and the packaging bag conveyor line 1 are arranged in sequence from front to back. The bag conveyor line 1 is arranged in the left-right direction. The bag opening assembly 2 is located in front of the right end of the bag conveyor line 1 (for the sake of convenience of description, this patent defines that the bag conveyor line 1 is conveyed to the right, and bagging is performed at the right end of the bag conveyor line 1, but this is not a limitation of this patent). The bag support assembly 3 is arranged in the front-to-back direction and is located directly in front of the bag opening assembly 2. The translation structure 5 can move in the front-to-back direction, and its forward movement allows the bag opening assembly 2 to move forward to the bag support assembly 3. The translation structure 5 is arranged in the front-to-back direction and is located on the right side of the bag support assembly 3. It is specifically an electric guide rail slide. The vertical beam 6 is arranged vertically and fixed on the right side of the slide of the translation structure 5. It is located on the right side of the bag support assembly 3, and a slide rail is provided on the left side along the vertical direction.

[0031] The bag conveyor line 1 includes a negative pressure conveyor belt 11 arranged in a left-right direction and a support slide 12 adjacent to the front. The support slide 12 has a smooth surface and is flush with the negative pressure conveyor belt 11. The negative pressure conveyor belt 11 extends rightward relative to the support slide 12 to form a bagging section 13. A negative pressure chamber 14 (open at the top) below the negative pressure conveyor belt 11 is connected to the negative pressure extraction structure via a pipeline. No negative pressure chamber 14 is provided below the bagging section 13. In other words, the bag conveyor line 1 is divided from front to back into a negative pressure section and a bagging section 13. Below the negative pressure section is a negative pressure chamber 14, and adjacent to the front of the negative pressure section is a support slide 12. Specifically, the support slide 12 is fixed to the top front side of the front side of the negative pressure chamber 14 and has a width of 3-6 cm. Specifically, the drive motor of the translation structure 5 is located at the rear end. The rear end and the drive motor above it are located to the right of the negative pressure chamber 14 and below the bagging section 13.

[0033] Specifically, both the fixed suction mechanism 21 and the movable suction mechanism 22 include a suction bracket positioned horizontally and multiple suction cups (specifically, two square suction cups) arranged side by side on the bracket. The suction cups are connected to the negative pressure extraction structure via flexible hoses. For the fixed suction mechanism 21, the right end of the suction bracket is fixed to the vertical beam 6, with the suction cup facing upward and positioned immediately in front of and below the negative pressure conveyor belt 11. For the movable suction mechanism 22, the suction bracket slides onto a slide rail via a slide, with its right end fixedly connected to the timing belt.

The frame 33 is a gantry-type bracket arranged in a horizontal direction. The rotating shaft 34 is arranged vertically, with its upper and lower ends rotatably mounted on the frame 33. The two bag-supporting jaws 31 are positioned opposite each other, with the distance between them gradually decreasing from front to back. They can be rotated outward to position themselves in a forward-backward direction. Two isosceles trapezoidal plates, each larger in front than in back, are positioned between the two bag-supporting jaws 31. These plates are located above and below the bag-supporting jaws 31, respectively, and are fixed to the frame 33. The two isosceles trapezoidal plates and the two bag-supporting jaws 31 form a rectangular frame structure that mates with the packaging bag. The positioning ring 35 is equipped with a positioning rod that cooperates with a photoelectric sensor 37. Specifically, the positioning rod is positioned radially along the positioning ring 35, while the photoelectric sensor 37 is positioned vertically downward. A limiting arm and a driving arm are respectively positioned radially along the driving ring 36 on opposite sides of the driving ring 36. A positioning post 39 is positioned vertically, located behind and outside the corresponding rotating shaft 34. Specifically, it is a rubber cylinder. The limiting arm is located outside the driving ring 36 and abuts against the front side of the positioning post 39. The two drive cylinders 32 are used to drive the two rotating shafts 34 to rotate, and they are driven synchronously.

The tension spring 38 is arranged diagonally inward from back to front, with its front end connected to the upper side of the drive arms and its rear end connected to the frame 33. When the drive cylinders 32 are extended, the limit arm rests on the positioning column 39, and the bag-holding claws 31 are arranged at an angle. When the drive cylinders 32 are retracted, the bag-holding claws 31 are arranged in a front-to-back direction, and the positioning rod is located directly below the photoelectric sensor 37.

[0035] Preferably, the outer rear parts of the upper and lower bag-supporting claws in the embodiment of the present invention are both provided with buffer strips. Specifically, the buffer strips are thin foam plates (rectangular plates) arranged in the front-back direction and fixed by gluing.

The upper and lower bag-supporting claws are mounted on a rotating shaft 34 and can be adjusted vertically (via an adjustment seat), and both are L-shaped. An isosceles trapezoidal plate is mounted on a frame 33 and can be adjusted vertically. A positioning column 39 is mounted on the frame 33 and can be adjusted in position. Both the positioning ring 35 and the driving ring 36 can be rotated and adjusted on the rotating shaft 34 and locked with corresponding bolts. For packaging bags 4 of different specifications, the vertical position of the movable adsorption mechanism 22 is adjusted as needed (servo control).

[0039] In the embodiment of the present invention, the outer front ends of both the upper and lower bag-supporting jaws are equipped with adjustment seats (with a circular hole vertically defined thereon for the shaft 34 to pass through). The adjustment seats are mounted on the shaft 34 so as to be adjustable up and down and are locked with corresponding bolts. Adjustment brackets are mounted on the upper and lower sides of the upper and lower isosceles trapezoidal plates. These brackets are vertically arranged and have first vertically defined slots. The brackets are secured to the frame 33 via first locking bolts (disposed in the front-to-back direction) that pass through these slots. Positioning posts 39 are mounted on the inclined plate, which is arranged diagonally inward from front to back and has second slots defined thereon. The inclined plate is secured to the frame 33 via second locking bolts (disposed vertically) that pass through these second slots. In this patent, adjustment is achieved by loosening the corresponding bolts.

[0040] Among them, "first" and "second" in this patent only serve to distinguish and have no other special meanings.
