In this embodiment, the front end face refers to the face of the packaging bag 1 where the wing-shaped bag edge 102 is located.
[0045] Such as Figures 2 to 8As shown, the folding device in this embodiment includes a folding mechanism 3, which includes a pushing component 302, a rotating angle folding component 301 symmetrically arranged on both sides of the pushing component 302, and an inserting angle driving member 2 connected to the rotating angle folding components 301 on both sides and driving the rotating angle folding components 301 on both sides to be relatively close to or away from each other; the pushing component 302 includes a pushing plate 3022 and a pushing plate driving member 3021; the rotating angle folding component 301 includes a rotating driving member 3013 and a paddle 3012; when the packaging bag 1 to be folded is conveyed to the folding mechanism 3, the pushing plate 3022 is located on the front side of the front end of the packaging bag 1 to be folded, and the paddle 3012 is located on the folding ears at both ends of the front end of the packaging bag 1 to be folded 101 rear side; the push plate driving member 3021 drives the push plate 3022 to move and press against the front end face of the packaging bag 1 to be folded; the angle driving member 2 drives the rotating angle folding components on both sides to be relatively close, so that the paddle of the rotating angle folding component moves to the rear side of the folding ear, and the rotating driving member 3013 drives the paddle 3012 to rotate the set angle, and the folding ears 101 at both ends of the front end face of the packaging bag 1 to be folded are rotated and folded toward the front end face; the push plate 3022 in the pushing component 302 presses against the front end face of the packaging bag 1 to be folded, and at the same time, the paddle 3012 in the rotating angle folding component 301 is also inserted into the two folding ears 101 sides of the packaging bag 1, and drives the folding ears 101 on both sides to fold toward the front end face of the packaging bag 1 through rotation.
[0046] like Figure 7 As shown, in the original state, the push plate 3022 and the paddle 3012 are arranged one after the other, and the paddle 3012 is located closer to the material conveying line. In the folded state, the relative positions of the paddle 3012 and the push plate 3022 are swapped, and the push plate 3022 is located closer to the material conveying line. Figure 8 shown.

The angle drive member 2 can also be an electric push rod or other driving device, and the rotation drive member 3013 can be a servo motor or other power device that can drive the pick 3012 to rotate.

The push plate driving member 3021 can be a cylinder, an electric push rod or other power devices that can drive the push plate to do reciprocating linear motion.
[0049] The folding mechanism of the utility model realizes efficient folding of packaging bags on an assembly line through dynamic cooperation among a pushing component, a rotating corner folding component and an inserting corner driving member, thereby improving the production efficiency of packaged food.

[0052] Embodiment 3
[0053] As a preferred embodiment of the present utility model, on the basis of Embodiment 1, a food packaging bag folding device for a production conveyor line in this embodiment further includes a translation driving assembly 4, and the folding mechanism 3 is assembled on the translation driving assembly 4, and the folding mechanism 3 is driven by the translation driving assembly 4 to reciprocate along the conveying direction of the packaging bag to be folded (as shown in ④ in Figure 10 ).
[0054] Preferably, the translation driving assembly in this embodiment adopts a servo chain drive structure form. As shown in Figure 9 , the translation driving assembly 4 includes a servo driving motor 402, a sprocket 401 driven by the servo driving motor 402, and a chain meshing with the sprocket 401, and the folding mechanism 3 is connected to the chain. The servo driving motor 402 drives the sprocket 401 to rotate clockwise or counterclockwise, so as to drive the entire folding mechanism 3 to reciprocate linearly along with the chain. In addition, the translation driving assembly can also adopt a structure of a servo motor + synchronous belt assembly, or a structure of a slide rail, a slider, a servo motor + crank connecting rod, or a structure of a servo motor + screw, or a linear driving motor.
[0055] The working process of the translation driving assembly 4 is as follows:
[0056] When the folding mechanism completes the folding of the packaging bag, the translation driving assembly 4 drives the folding mechanism 3 to move synchronously along the conveying direction with the packaging bag 1 until the packaging bag 1 enters the baffle area and is conveyed in a folded state under the limiting action of the baffle; when the packaging bag is conveyed in place, the translation driving assembly 4 drives the folding mechanism 2 to return to the original position.
[0057] Embodiment 4

[0059] Preferably, in this embodiment, the lifting drive assembly adopts a lifting slide rail machine. The translation drive assembly 4 is integrally connected to the lifting slide rail machine and is driven by the lifting slide rail machine to move up and down reciprocally along the slide rail together with the folding mechanism. Specifically, the lifting slide rail machine includes a guide rail 501, a first swing arm 502, a second swing arm 503, and a servo control motor 504.

The servo control motor 504 drives the first swing arm 502 to swing, and the first swing arm 502 drives the second swing arm 503 to swing, thereby driving the translation drive assembly 4 and the folding mechanism 3 to move up and down reciprocally along the guide rail 501.
[0060] Similarly, the lifting drive assembly can adopt the structure of a servo motor + synchronous belt assembly, or the structure of a slide rail, a slider, a servo motor + crank connecting rod, or the structure of a servo motor + lifting screw, or a linear drive motor.
[0061] The working principle of the present utility model is as follows:
[0062] Step 1: The packaging bag to be folded is conveyed to the bag folding station. The lifting drive assembly 5 drives the folding mechanism 3 to move integrally to the position where the packaging bag is located, so that the push plate 3022 in the pushing assembly 302 is located in front of the front end face of the packaging bag 1, and the flap 3012 is located on the rear side of the folded ears 101 at both ends of the front end face of the packaging bag 1 to be folded.
[0063] Step 2: The corner inserting drive member 2 drives the rotating corner folding assemblies on both sides to move relatively closer, so that the flaps of the rotating corner folding assemblies move to the rear side of the folded ears. The rotating drive member 3013 drives the flap 3012 to rotate by a set angle, and folds the folded ears 101 at both ends of the front end face of the packaging bag 1 to be folded forward to the front end face. The push plate 3022 in the pushing assembly 302 abuts against the front end face of the packaging bag 1 to be folded. At the same time, the flaps 3012 in the rotating corner folding assembly 301 also insert into the sides of the two folded ears 101 of the packaging bag 1 and drive the two folded ears 101 to fold towards the front end face of the packaging bag 1 by rotation.
[0064] Step 3: The translation drive assembly 4 drives the folding mechanism 3 to move synchronously with the packaging bag 1 along the conveying direction until the packaging bag 1 enters the baffle area and is conveyed in a folded state under the limiting action of the baffle.
[0065] Step 4: The lifting drive assembly 5 drives the folding mechanism 3 to move upward as a whole and withdraw from the packaging bag 1, and then returns to the original position under the drive of the translation drive assembly 4. During the return process, the pushing assembly 302 and the rotating corner folding assembly 301 of the folding mechanism 3 are reset to the original state, and continue to fold the next arriving material packaging bag 1. Repeat this process to complete the continuous folding work.
