Description

Technical Field

[0001] This utility model relates to packaging bag production equipment, specifically to a double-layer pressure point mechanism for zipper packaging bags. Background Technology

[0002] A zippered bag is a type of packaging bag with a zipper at the opening. The zipper allows the bag to be opened and closed. To improve the aesthetics of the zipper and facilitate opening the zipper using friction, pressure points are applied to the opening, creating a dense network of indentations. A drawback of traditional pressure point mechanisms is that during pressure point application, both layers of the packaging bag substrate are simultaneously pressed between the same pressure point roller and rubber roller. With this method, the layer of packaging bag substrate in contact with the pressure point roller experiences stronger pressure, resulting in better pressure point formation. The other layer experiences weaker pressure, leading to inconsistent pressure point quality between the two layers at the bag opening. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by this utility model is to provide a double-layer pressure point mechanism for a zippered packaging bag to solve the above-mentioned problem.

[0004] Therefore, this utility model is implemented using the following solution:

[0005] A double-layer pressing mechanism for a zippered packaging bag is characterized by: a mounting frame having a clearance groove for the double-layer packaging bag substrate to pass through; a first cutting blade being positioned near the clearance groove; and a first pressing roller group and a second pressing roller group being positioned to the left and right above the first cutting blade. One layer of the packaging bag substrate, after being cut by the first cutting blade, is pressed by the first pressing roller group, and the other layer of the packaging bag substrate is pressed by the second pressing roller group.

[0006] The first pressure roller group includes a first rubber roller and a first pressure roller pressed together, with raised points arranged on the first pressure roller. The second pressure roller group includes a second rubber roller and a second pressure roller pressed together, with raised points arranged on the second pressure roller.

[0007] The mounting bracket is provided with a slide block at its bottom, and the slide block is slidably mounted on the slide rod.

[0008] The above-mentioned technical solution provides a double-layer pressing mechanism for a zippered packaging bag. By setting a cutting blade, the open ends of the two layers of packaging bags can be cut. Then, one layer is pressed by a first pressing roller group, and the other layer of packaging bag substrate is pressed by a second pressing roller group. This ensures that both layers of packaging bags are subjected to the same extrusion force, thus ensuring the pressing quality of each layer of packaging bag. Attached Figure Description

[0012] Figure 3 This is a side view of the present invention. Detailed Implementation

[0013] As shown in the figure, the present invention discloses a double-layer pressing mechanism for a zippered packaging bag, including a mounting frame 1. The mounting frame 1 is provided with a clearance groove 2 for the double-layer packaging bag substrate to pass through. A first cutting blade 3 is provided near the clearance groove 2. A first pressing roller group and a second pressing roller group are provided on the left and right sides above the first cutting blade 3. After being cut by the first cutting blade 3, one layer of packaging bag substrate is pressed by the first pressing roller group, and the other layer of packaging bag substrate is pressed by the second pressing roller group.

[0014] Furthermore, the first pressure roller assembly includes a first rubber roller 7 and a first pressure roller 8 pressed together, with raised points arranged on the first pressure roller 8. The second pressure roller assembly includes a second rubber roller 4 and a second pressure roller 5 pressed together, with raised points arranged on the second pressure roller 5. Using the above structure, by cooperating with the rubber rollers and the pressure rollers, pressure point processing can be achieved on the passing packaging bag substrate.

[0015] Furthermore, a slide block 9 is provided at the bottom of the mounting frame 1, and the slide block 9 is slidably mounted on the slide rod. With the above structure, the mounting frame 1 can be moved to adjust the left and right positions of the cutting blade and the pressure roller assembly, thereby adapting to the production needs of packaging bags of different specifications.

[0016] The working principle of this utility model is as follows: the traction component simultaneously tractions two layers of packaging bag substrate, and the packaging bag substrate first passes through the first cutting blade 3 to cut out the open end of the packaging bag substrate. Then, one layer of packaging bag substrate is traction through the first pressure roller group. The first rubber roller 7 and the first pressure roller 8 in the first pressure roller group will press the packaging bag substrate and rotate passively under the action of friction, thereby continuously performing pressure processing on the packaging bag substrate. The other layer of packaging bag substrate is traction through the second pressure roller group and performs pressure processing in the same way. After that, the packaging bag substrate is traction to the next station for subsequent packaging bag forming operations.
