Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging bag forming, in particular to a packaging bag forming device. Background Art
[0002] Packaging bags are bags used to pack various items, making it easy to transport and store goods during production and circulation. They are widely used in daily life and industrial production.
[0003] During the production process, packaging bags need to be shaped and smoothed for easy rolling. Since the packaging bag production line is long, the packaging bags are relatively loose, which makes it easy for wrinkles to overlap during the smoothing process, resulting in the packaging bags being not flat. When wrinkles overlap, the packaging bags are basically flattened once through a flattening roller after manual adjustment, and the wrinkles cannot be flattened multiple times, resulting in poor flattening effect of the wrinkles. Therefore, in order to solve this problem, we proposed a packaging bag forming device. Utility Model Content

[0007] Working principle:
[0008] Before use, the distances between the pre-pressing roller, the pressing roller, the four sets of squeezing rollers and the shaping roller and the conveying roller below are adjusted by moving the seven rotating shafts vertically; the position of the squeezing roller on the rotating shaft is adjusted.
[0009] When in use, the external equipment drives the packaging bag to be transported toward the operating table, and the shaping rod guides and squeezes the M-shaped folded edge of the packaging bag after it has been folded; the packaging bag after passing the shaping rod successively passes between the conveying roller and the pre-pressing roller, between the conveying roller and the crimping roller, between the four sets of conveying rollers and the squeezing rollers, and between the conveying roller and the shaping roller, thereby completing the shaping of the packaging bag.
[0010] Beneficial effects:
[0011] In this solution, by setting a shaping rod, the M-shaped fold of the folded packaging bag is guided and squeezed, thereby avoiding deformation of the bag mouth and misalignment of the M-shaped fold;
[0012] By setting a pre-pressing roller, a creasing roller, four groups of squeezing rollers and a shaping roller, the pre-pressing roller pre-extrudes the packaging bag and performs preliminary shaping on the packaging bag; the creasing roller squeezes the center line of the packaging bag to prevent the packaging bag from deviating during transportation; the four groups of squeezing rollers repeatedly squeeze the M-shaped folded edge of the packaging bag and flatten it multiple times to improve the flattening effect of the folds; the shaping roller squeezes the surface of the packaging bag as a whole, which can effectively squeeze and limit the packaging bag to a large extent;

[0024] The axes of the pre-pressing roller 5, the crimping roller 6, the four groups of squeezing rollers 7 and the shaping roller 8 are respectively arranged to be in the same vertical plane as the axes of the corresponding conveying rollers 3, so as to effectively and specifically realize squeezing of the packaging bags conveyed between the conveying roller 3 and the pre-pressing roller 5, between the conveying roller 3 and the crimping roller 6, between the four groups of conveying rollers 3 and the squeezing rollers 7, and between the conveying roller 3 and the shaping roller 8;
[0025] By setting a vertically movable rotating shaft 4, the vertical movement of the rotating shaft 4 drives the pre-pressing roller 5, the crimping roller 6, the four groups of squeezing rollers 7 and the shaping roller 8 to move vertically respectively, thereby changing the distance between the conveying roller 3 and the pre-pressing roller 5, between the conveying roller 3 and the crimping roller 6, between the four groups of conveying rollers 3 and the squeezing roller 7, and between the conveying roller 3 and the shaping roller 8, so as to adapt to squeezing packaging bags of different thicknesses;
[0026] By providing a squeezing roller 7 that can move horizontally along the length direction of the rotating shaft 4, the position of the squeezing roller 7 on the rotating shaft 4 is changed to adapt to squeezing the folded edges on packaging bags of different widths.
[0027] like Figure 1 and Figure 2 As shown, sliding grooves 9 are provided on both side walls of the operating table 1, and sliders 10 are provided in the sliding grooves 9. The two sliders 10 provided on both sides of the operating table 1 form a group, and the two ends of each rotating shaft 4 are respectively rotatably provided between the two sliders 10 of each group; a screw rod 11 is threadedly penetrated through the top of the slider 10, and the two sides of the slider 10 are in contact with the two side walls of the sliding groove 9, and a mounting block 12 is provided above each of the sliding grooves 9, and one end of the screw rod 11 is a light circular segment, and the light circular segment passes through the mounting block 12 and is rotatably connected to the mounting block 12 through a bearing.

[0029] like Figure 1 and Figure 2 As shown, a support ring 13 is fixed on the top of the screw rod 11, and a through hole 14 is opened below the support ring 13. The through hole 14 is used to receive a force rod externally so as to rotate the screw rod 11 to drive the slider 10 to move vertically. By providing the support ring 13 and the through hole 14, the operator inserts the force rod into the through hole 14, thereby rotating the screw rod 11 with more effort.
