[0002] With the development of industrial technology, the production of packaged food is becoming more and more intelligent and automated to meet the needs of manufacturers to improve production efficiency and expand economic benefits. For the production of some special shaped packaged foods, such as sandwiches or triangular sliced ​​cakes, after the packaged food is bagged and vacuum sealed, a wing-shaped bag edge will be formed at one end of the product, and folded ears will be formed on both sides of the bag. The shape is as follows: Figure 1 In the production line of triangular packaged food, it is necessary to shape the semi-finished packaging bag, adjust the wing-shaped bag edge and the folding ears to make it convenient to fold, so as to cooperate with the folding action of the packaging bag in the subsequent process.

[0003] In the prior art, patent CN214139239U discloses a food packaging folding machine, whose structure includes a conveyor belt, on which a number of packaging bags are placed, and on which a corner shaping device is provided, which presses out the edges and corners on the packaging bags, and on which a folding device is provided, which folds the edges and corners on one side of the packaging bags, and on which a folding bar is provided on one side of the folding device, which folds the edges and corners on the other side of the packaging bags, and automatically completes the corner shaping and folding and gluing of the packaging bags in an assembly line manner, thereby improving production efficiency.

[0004] The above patent mentions that a corner shaping device is provided to press out the edges and corners on the packaging bag B. The corner shaping device includes a downward pressing device and a positive pressure device. The downward pressing device will press down on the edges and corners on both sides of the packaging bag B, and the positive pressure device will press positively on the front of the packaging bag B to make the edges and corners of the packaging bag B protrude. The first cylinder piston of the downward pressing device in the corner shaping device extends downward, and the pressing plate will extend to the edge of the packaging bag B. After the second cylinder of the positive pressure device pushes the push plate forward, the shaping of the edges and corners of the packaging bag B is completed. The comparative patent uses a push plate and a pressure plate to shape the packaging bag. Since the packaging bag is relatively soft, the hard plate-like structure cannot smooth the wrinkles on the surface of the packaging bag, resulting in poor shaping effect and even affecting subsequent processes.

Figure 1 The figure shows a typical packaging bag structure to be shaped applicable to the present invention. After the bagging and plastic sealing, the material forms a horizontal wing-shaped bag edge 102 in the middle of the front end surface of the packaging bag 1, and at the same time forms symmetrical folding ears 101 at both ends of the front end surface. In this embodiment, the front end surface refers to the surface of the packaging bag 1 where the wing-shaped bag edge 102 is located.

[0040] The shaping device of the utility model comprises a first shaping mechanism 2 and a second shaping mechanism 3 arranged on the material conveying line. Figure 2 As shown, the first shaping mechanism 2 includes a first shaping member 203 and a first driving member 201; the second shaping mechanism 3 includes a second shaping member 302 and a second driving member 301; when the packaging bag 1 to be shaped is conveyed to the shaping device, the first driving member 201 drives the first shaping member 203 to approach and shape the rear surfaces of the two folded ears 101 of the packaging bag 1 to be shaped from the middle to both sides; the second driving member 301 drives the second shaping member 302 to shape the wing-shaped bag edge 102 on the front end surface of the packaging bag 1 to be shaped from top to bottom.

Preferably, the first shaping member and the second shaping member can be a brush roller, a sponge roller, a rubber tube, etc. The first shaping member 203 and the second shaping member 302 are both driven by a motor and are in a rotating state. Since the first shaping member, the second shaping member and the packaging bag are in soft contact and the contact area is large, the packaging bag has a good shaping effect, which is conducive to improving the shaping quality of the packaging bag, and then improving the packaging quality of subsequent processes.

[0045] Furthermore, in this embodiment, the first driving member 201 is connected to the first shaping member 203 and drives the first shaping member 203 to reciprocate between the first station and the second station. When the first shaping member 203 is in the first station, the first shaping member 203 contacts the rear side surfaces of the folded ears 101 at both ends of the front end surface of the packaging bag 1 to be shaped to complete the shaping. Figure 4 When the first shaping member 203 is in the second station, the first shaping member 203 is separated from the packaging bag and leaves space for the next packaging bag to be shaped to enter, such as Figure 3 shown.
