[0055] The following is a detailed description of an embodiment of the present invention. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific operation process are given, but the protection scope of the present invention is not limited to the following embodiment.

[0056] like Figure 1-8 As shown, a packaging material folding device for packaging bags includes a packaging table 1 (the packaging table 1 is a rectangular parallelepiped).

[0057] The left end of the packaging table 1 is equipped with a side folding device 4 (the side guide plate is spaced apart from the side wall of the left end of the packaging table 1). The function of the side folding device 4 is to lift up the sides of the flat packaging materials such as packaging film or packaging paper to form a folded portion (in an approximately vertical state).

[0058] The packaging table 1 is equipped with a side flattening device 3 that cooperates with the side folding device 4. The function of the side flattening device 3 is to flatten the folded parts on both sides to form a folded part. At this time, the folded part covers the packaging material. At this time, the bottom is the packaging material body, and the two sides are folded onto the body.

[0059] The specific structure of the side folding device 4 is as follows:

[0060] The side folding device 4 includes a side guide plate 43 (the side guide plate 43 is connected to a column 42 , and the column 42 is connected to the plate body of the side guide plate 43 in a penetrating manner).

[0061] The top of the column 42 is connected to the E-shaped rod 41, and the column 42 is connected to the middle part of the E-shaped rod 41. The E-shaped rod 41 is in an inverted E shape. The two ends of the E-shaped rod 41 are welded to the side walls of the groove plate 523 described below to fasten the side guide plate 43. The side guide plate 43 is a vertical end plate, and its function is to guide the folding of the packaging material. Prevent the packaging material that has been tilted on both sides from collapsing downward. At the same time, in order to increase the guiding effect, two guide blocks 431 are connected to the lower end of the right side wall of the side guide plate 43, and the guide blocks 431 are arranged at intervals.

[0062] The lower end of the left side wall of the side guide plate 43 is connected to the rolling device 44, which includes a leveling column 441, which is rotatably connected to a column barrel 4411, and the top of the column barrel 4411 is connected to the side guide plate 43 through a connecting rod. Specifically, the connecting rod is connected to the side guide plate 43 in an inclined manner. A nut is provided at the end of the connecting rod, and a connecting end plate 442 is vertically welded to the side guide plate 43, and a bolt is screwed to the connecting end plate 442, and the bolt is screwed to the nut to achieve the connection of the leveling column 441.

[0063] The function of the flattening device 44 is that the cylinder 4411 contacts the packaging material to flatten the packaging material and prevent the packaging material from forming wrinkles.

[0064] Two side forming devices 5 are arranged on the side guide plate 43 , and the side forming devices 5 are symmetrically arranged on the front and rear sides of the side guide plate 43 .

[0065] Each side forming device 5 comprises a guide rod 51, one end of which has a bending portion 511, and the bending portion 511 is used for side forming of packaging materials; the other end of the guide rod 51 is connected to a first connecting member 52. The first connecting member 52 is connected to the left end of the packaging table 1.

[0066] That is, the front end of the guide rod 51 on the side forming device 5 located at the rear side has a bending portion 511, and the rear end of the guide rod 51 on the side forming device 5 located at the front side has a bending portion 511. The bending portions 511 on the two side forming devices 5 are close to each other, and at the same time, the bending portions 511 are inclined downward. The two bending portions 511 are located on the same inclined plane.

[0067] The bending portion 511 is located at the front and rear sides of the side guide plate 43 (the bending portion 511 and the side guide plate 43 are spaced apart). After the side guide plate 43 lifts the packaging material, the bending portion 511 serves to continuously lift the side of the packaging material to prevent collapse (the packaging material continuously moves from left to right, the side guide plate 43 continuously lifts the side, and the lifted side, under the action of the bending portion 511, continuously rises and takes shape).

[0068] The other end of the guide rod 51 is connected to a first connecting member 52 , and the first connecting member 52 is connected to the left end of the packaging platform.

[0070] The bottom of each connecting column 522 is connected to a limiting plate 521 (the limiting plate 521 is a cube); the bottom of the limiting plate 521 is connected to a slot plate 523 (the slot plate 523 is a rectangular parallelepiped) via a fastening bolt 5222 , and the right side wall of the slot plate 523 is welded to the left side wall of the packaging table 1 .

[0071] A groove 5231 is formed at the top of the groove plate 523, and a plurality of screw holes 52311 are formed at the bottom of the groove 5231 to match the fastening bolts 5222, and the fastening bolts 5222 are screwed into the screw holes 52311; a first butterfly-shaped knob 5221 is welded at the top of the connecting column 522. By rotating the first butterfly-shaped knob 5221, the connecting column 522 rotates, and at this time, the horizontal inclination angle of the guide rod 51 and the bending portion 511 can be changed (it is convenient to adjust the angle accordingly according to the properties of the packaging material, and increase the effect of the side upward warping molding).

[0072] After the side edges of the packaging material are warped upward by the side edge forming device 5, the side edges need to be flattened to form a flattened state on both sides for easy sealing.

[0073] Therefore, a side flattening device 3 is installed on the right side of the side forming device 5, that is, on the packaging table 1.
