Description

Technical Field

[0001] This utility model relates to the field of sealing bag sealing technology, and more specifically, it relates to a sealing bag opening forming and pressing device. Background Technology

[0002] Currently, sealed bags have a wide variety of external structures during the production process.

[0003] Under the complex external structure, one of the steps involves folding and forming. This step requires a shaping heating and shaping cooling device. Currently, the reason for most shaping failures is that before shaping heating, the folded sealing bag roll will experience tension rebound due to the transmission tension. However, the likelihood of tension rebound depends on the thickness of the sealing bag. Thicker sealing bags rebound faster and more, while thinner sealing bags rebound less. Utility Model Content

[0004] The purpose of this invention is to provide a sealing bag opening forming and pressing device, a device that can achieve continuous sealing and a shaped and sealed bag opening.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sealing bag mouth forming and pressing device, including a worktable, an anti-slip group, a folding group, a shaping group, a heating group and a pressing group.

[0006] A workbench, with a vertical wall on one side of the workbench surface, and the direction of the intersection of the vertical wall and the top surface of the workbench is the flow processing direction.

[0009] The shaping unit is used for heating and shaping the sealed bags after they have been formed and folded to create folds.

[0010] Heating unit, used for preheating before sealing bag forming;

[0011] The forming assembly is used for heating and forming to fix the sealed bags after they have been formed and folded.

[0036] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0038] Example

[0039] like Figure 1 , Figure 2 , Figure 3 As shown, a sealing bag opening forming and pressing device includes a worktable 1, an anti-slip group 2, a folding group 3, a shaping group 4, a heating group 5, and a pressing group 6.

[0040] Workbench 1, with a vertical wall 11 on one side of the workbench 1. The direction of the intersection of the vertical wall 11 and the top surface of the workbench 1 is the flow processing direction. From the starting end of the flow processing direction, anti-slip group 2, folding group 3, shaping group 4, heating group 5 and pressing group 6 are arranged in sequence.

[0041] Anti-slip group 2 is used to control the anti-slip tension of sealed bags and the processing speed of sealed bags.

[0042] The anti-slip assembly 2 includes two anti-slip rollers 21 that are vertically arranged on the vertical wall 11 and located on the same vertical plane. The two anti-slip rollers 21 are arranged side by side and abut against each other.

[0043] The flow rate of the roll material can be controlled by the mutual contact, ensuring that the roll material is conveyed neither too fast nor too slow, thereby stably controlling the tension range during the processing.

[0044] Folding assembly 3 is used for forming and folding the sealed bag. The folding assembly 3 includes a first folding roller 31, a second folding roller 32, and a third folding roller 33 arranged vertically on the vertical wall 11 and side by side. The first folding roller 31, the second folding roller 32, and the third folding roller 33 are located on the same horizontal plane. The folding assembly 3 also includes a first shaping roller 34 and a second shaping roller 35 arranged side by side. The first shaping roller 34 and the second shaping roller 35 are both located on the same horizontal plane and at the bottom of the horizontal plane of the first folding roller 31, the second folding roller 32, and the third folding roller 33. The first shaping roller 34 and the second shaping roller 35 are respectively arranged between the first folding roller 31 and the second folding roller 32 and between the second folding roller 32 and the third folding roller 33. The first folding roller 31, the second folding roller 32, the third folding roller 33, the first shaping roller 34, and the second shaping roller 35 are all provided with guide grooves.

[0045] Through multiple folds and multiple shaping processes, such as Figure 2 As shown, the sealing bag roll first passes through the anti-slip roller 21, then through the first folding roller 31, and then enters from the right side of the first shaping roller 34. After passing through the first shaping roller 34, it exits from the top left side, and then passes through the second folding roller 32 and the third folding roller 33 in sequence. Finally, it enters from the right side of the second shaping roller 35 and exits from the left side into the shaping group 4. After multiple windings, the springback caused by tension can be effectively solved. After two tension pressure moldings, the springback will become slower. And after multiple windings, even if the previously output part has springbacked, it will not affect the processing of the next section of the sealing bag and will not cause subsequent recovery due to springback.

[0046] Shaping unit 4 is used for heating and shaping the sealed bag after it has been formed and folded to form a fold.

[0047] The shaping assembly 4 includes a mounting rod 42 disposed on the vertical wall 11. The mounting rod 42 is provided with two shaping rollers 41 that are at an angle to each other. One shaping roller 41 is inclined in the positive direction of the flow processing direction, and the other shaping roller 41 is inclined in the opposite direction of the flow processing direction.

[0048] The included angle between the axes of the two shaping rollers 41 is 30°.

[0049] In this design, in order to achieve better shaping, both shaping rollers 41 can simultaneously contact the sealed bag.

[0050] In this scheme, if necessary, the shaping roller 41 is moved closer to one of the folding groups 3 as the heating roller 51.

[0051] Heating unit 5 is used for preheating before sealing the bag.

[0052] The heating group 5 includes at least one heating roller 51 arranged side by side on the vertical wall 11.

[0053] Compression molding unit 6 is used for heating and pressing to fix the sealed bag after it has been formed and folded.

[0054] The forming assembly 6 includes two forming rollers 61 that are set on the vertical wall 11 and located on the same vertical plane.

[0055] The forming roller 61 can be heated and formed.

[0056] Each of the guide grooves is provided with a folded protrusion ring.

[0057] Working principle: The vertical wall 11 on the workbench 1 ensures that all components are installed on the same plane. Installation is convenient as long as the slotting and rotation direction are set according to the regulations.

[0058] The anti-slip group 2 effectively prevents progress retraction caused by subsequent winding, thus accelerating the release of the coil.

[0059] The combination of folding group 3 and shaping group 4 can directly solve the problem of tension recovery caused by the combination of wall thickness and roll tension. The addition of a shaping roller to folding group 3 can prevent tension recovery by non-single shaping before heating. Then, the shaping roller 41 of the subsequent shaping group 4 can prevent recovery again and perform secondary shaping, thus solving the problem of tension recovery caused by sealing the bag opening during the transition period and after folding.

[0060] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.

[0061] Furthermore, the specific embodiments described above are exemplary.
