[0033] Embodiment 1:

[0034] Please refer to Figure 1-7, this embodiment provides a bagging component for an automatic formula cut tobacco bagging machine. The main function of the bagging component of the automatic formula cut tobacco bagging machine is to accurately fit a pre-prepared plastic bag into a carton for subsequent filling and sealing operations of the formula cut tobacco. The bagging component of the automatic formula cut tobacco bagging machine in this embodiment includes a lifting device 10, an opening device 20, and a bag supporting device;

[0035] The lifting device 10 includes a mounting frame 11. The mounting frame 11 is mainly a frame structure composed of several profiles and sheet metal materials, providing support and a mounting foundation for each component, and mounting this bagging component on the bagging machine frame through the mounting frame 11.

[0036] The mounting frame 11 is vertically provided with a slide rail. A slider is provided on the back of the lifting mounting plate 12. The lifting mounting plate 12 is slidably connected to the mounting frame 11 through the cooperation of the slide rail and the slider, so that the lifting mounting plate 12 can move back and forth in the height direction of the mounting frame 11, driving the opening device 20 and the bag supporting device to move in the height direction.

[0037] The opening device 20 includes a lifting frame 21. The end of the lifting frame 21 is fixed to the lifting mounting plate 12. A number of reinforcing rib plates are provided at the connection between the lifting frame 21 and the lifting mounting plate 12, thus improving the connection strength between the lifting frame 21 and the lifting mounting plate 12 and the stability of the lifting frame 21.

[0038] The bottom surface of the lifting frame 21 is horizontally provided with a slide rail. Sliders are fixed on both the first opening plate 22 and the second opening plate 23. Through the cooperation of the slide rail and the slider, the first opening plate 22 and the second opening plate 23 are respectively slidably connected to the bottom surface of the lifting frame 21, so that the first opening plate 22 and the second opening plate 23 can move back and forth in the horizontal direction of the lifting frame 21.

[0039] The bag supporting device includes a first bag supporting assembly 30 and a second bag supporting assembly 40. The first bag supporting assembly 30 is arranged on the first opening plate 22, and the second bag supporting assembly 40 is arranged on the second opening plate 23, so that the first bag supporting assembly 30 and the second bag supporting assembly 40 move back and forth in the horizontal direction of the lifting frame 21 driven by the first opening plate 22 and the second opening plate 23, and the two can approach or move away from each other; the first bag supporting assembly 30 includes a first inner bag supporting structure 31 and a first outer bag supporting structure 32, and a gap for the passage of the carton board is formed between the first inner bag supporting structure 31 and the first outer bag supporting structure 32; the second bag supporting assembly 40 includes a second inner bag supporting structure 41 and a second outer bag supporting structure 42, and a gap for the passage of the carton board is formed between the second inner bag supporting structure 41 and the second outer bag supporting structure 42.

[0040] Based on the above structure, during use, the open plastic bag is moved by the preceding components of the automatic bagging machine to the lower part of the bagging component. The lifting device 10 drives the opening device 20 and the bag supporting device installed on the lifting frame 21 to descend. The initial state of the first bag supporting assembly 30 and the second bag supporting assembly 40 is a gathered state where they are close to each other. The first bag supporting assembly 30 and the second bag supporting assembly 40 in the gathered state enter the plastic bag under the drive of the lifting device 10. Subsequently, the first opening plate 22 and the second opening plate 23 on the opening device 20 drive the first bag supporting assembly 30 and the second bag supporting assembly 40 to move away from each other, tightly stretching the mouth of the plastic bag between the first bag supporting assembly 30 and the second bag supporting assembly 40. The lifting device 10 drives the first bag supporting assembly 30, the second bag supporting assembly 40, and the plastic bag supported between the first bag supporting assembly 30 and the second bag supporting assembly 40 to rise; when the cardboard box below is in place, the lifting device 10 drives the first bag supporting assembly 30, the second bag supporting assembly 40, and the plastic bag to descend. The first opening plate 22 and the second opening plate 23 drive the first bag supporting assembly 30 and the second bag supporting assembly 40 to adjust in the horizontal direction, aligning the box boards on the opposite sides of the cardboard box with the gaps between the first inner bag supporting structure 31 and the first outer bag supporting structure 32 of the first bag supporting assembly 30, and the gaps between the second inner bag supporting structure 41 and the second outer bag supporting structure 42 of the second bag supporting assembly 40 respectively. During the descent, the first outer bag supporting structure 32 and the second outer bag supporting structure 42 fold the mouth of the plastic bag outside the upper edge of the cardboard box. During the descent, the first inner bag supporting structure 31 and the second inner bag supporting structure 41 slide along the inner side wall of the cardboard box, pressing the inner plastic film of the plastic bag onto the inner wall of the cardboard box. Then, the opening device 20 drives the first bag supporting assembly 30 and the second bag supporting assembly 40 to converge, changing the plastic bag from a tightly stretched state to a relaxed state. Finally, the lifting device 10 drives the opening device 20 and the bag supporting device to rise, thus completing the entire bagging action, ensuring that the mouth of the plastic bag is stably supported at the box opening of the cardboard box, and the inner plastic film of the plastic bag is perfectly attached to the box wall of the cardboard box, and the bag mouth is not easily detached during the subsequent material filling process of the plastic bag.

[0041] Specifically, the first inner bag supporting structure 31 includes an inner supporting plate 311. The inner supporting plate 311 has a vertically arranged upright portion 3111 and a horizontally arranged horizontal portion 3112. The upright portion 3111 and the horizontal portion 3112 respectively smooth and attach the inner plastic film of the plastic bag on the side wall and the bottom wall of the cardboard box; a plurality of hollow holes 3113 are evenly distributed on the surface of the inner supporting plate 311, and the air pressures on both sides of the inner supporting plate 311 are connected through the hollow holes 3113 to avoid the formation of air pressure differences and the generation of air flow agitation to cause the plastic film to shift; transition rounded corners are formed at the edges of the inner supporting plate 311 to avoid damaging and pulling the plastic film during the contact between the inner supporting plate 311 and the plastic bag.

[0042] The first inner support bag structure 31 of this embodiment includes an inner support connecting frame 312 and an inner support driving member 313. The top end of the inner support connecting frame 312 is fixed to the bottom of the first opening plate 22. The inner support connecting frame 312 is slidably connected to the inner support plate 311, so that the inner support plate 311 can translate in the height direction relative to the inner support connecting frame 312. Specifically, circular flange linear bearings 314 are respectively fixed at both ends of the bottom of the inner support connecting frame 312. A guide post 315 is fitted and connected inside the circular flange linear bearing 314. The guide post 315 is vertically arranged, and the bottom end of the guide post 315 is connected to the horizontal part 3112 of the inner support plate 311. Thus, the inner support connecting frame 312 is slidably connected to the inner support plate 311, and the inner support plate 311 can translate in the height direction relative to the inner support connecting frame 312. The inner support driving member 313 has a fixed end and a telescopic end. The fixed end of the inner support driving member 313 is fixed to the inner support connecting frame 312, and the telescopic end of the inner support driving member 313 is connected to the inner support plate 311. After the first inner support bag structure 31 enters the carton, power is provided by the inner support driving member 313 to drive the inner support plate 311 to move back and forth in the height direction of the inner support connecting frame 312, so that the inner support plate 311 slides along the inner wall of the carton, further increasing the contact area between the inner support plate 311 and the carton. At the same time, the air between the plastic bag and the carton can be squeezed out through the back-and-forth movement, improving the conformity of the plastic bag to the inner wall of the carton.

[0043] The first outer support bag structure 32 of this embodiment includes a first outer support plate 321 and a second outer support plate 322. The first outer support plate 321 is connected to one end of the first opening plate 22 through a first adjusting block 3212, and the second outer support plate 322 is connected to the other end of the first opening plate 22 through a second adjusting block 3221. The first outer support plate 321 and the second outer support plate 322 are arranged opposite to each other; the positions of the first outer support plate 321 and the second outer support plate 322 respectively correspond to two adjacent folding corners of the carton. Inner folding corners 3211 are formed on the inner sides of both the first outer support plate 321 and the second outer support plate 322, and the inner folding corners 3211 are adapted to the outer edges of the carton; the mouth of the plastic bag is folded and pushed along the vertical edges of the carton by the first outer support plate 321 and the second outer support plate 322, improving the fitting degree between the mouth of the plastic bag and the box opening of the carton and the bagging efficiency. Long pull grooves are provided along the length direction at both ends of the first opening plate 22, and screws are inserted into the long pull grooves. One end of the screw is connected to the first adjusting block 3212 or the second adjusting block 3221, so that the first adjusting block 3212 or the second adjusting block 3221 is slidably connected to the first opening plate 22. By loosening the screw, the first adjusting block 3212 or the second adjusting block 3221 slides relative to the first opening plate 22, and by tightening the screw, the relative positions of the first adjusting block 3212 or the second adjusting block 3221 and the first opening plate 22 are locked, and thus the relative positions of the first outer support plate 321 and the second outer support plate 322 can be adjusted to adapt to the bagging requirements of cartons of different sizes. Transition rounded corners are formed at the edges of both the first outer support plate 321 and the second outer support plate 322, and the plastic film is prevented from being damaged and pulled during the contact between the first outer support plate 321, the second outer support plate 322 and the plastic bag by the transition rounded corners.

[0044] The second bag support assembly 40 of this embodiment has the same structure as the first bag support assembly 30, and the two are arranged opposite to each other. Those skilled in the art can understand this and will not be elaborated here.
