[0002] The heat sealing mechanism is a special component commonly used in various packaging equipment. Its main function is to heat seal and bond multiple layers of substrates. The traditional heat sealing mechanism mainly includes an upper heat sealing plate and a lower heat sealing plate. When working, the substrate passes between the upper and lower heat sealing plates, and then the upper and lower heat sealing plates approach each other and clamp the substrate to complete the heat sealing process. The defect of this structure in actual use is that during the heat sealing process, the heat sealing part of the substrate will shrink and deform to a certain extent due to the heat, resulting in some wrinkles at the heat sealing part of the substrate, affecting the heat sealing quality and aesthetics of the product.

[0010] An anti-wrinkle heat sealing mechanism of the above technical solution, BRIEF DESCRIPTION OF THE DRAWINGS
[0011] The utility model has the following drawings:
[0012] Figure 1 It is a structural schematic diagram of the utility model;
[0013] Figure 2 for Figure 1 A partial enlarged view of the area pointed by A in the middle;
[0014] Figure 3 for Figure 2 View without the swing arm. DETAILED DESCRIPTION
[0015] As shown in the figure, the utility model discloses an anti-wrinkle heat sealing mechanism, including an upper heat sealing plate 3 and a lower heat sealing plate 4. The upper heat sealing plate 3 is arranged at the bottom of the upper heating plate 2 of the upper lifting seat 1, and the lower heat sealing plate 4 is arranged on the top of the lower heating plate 5 on the lower lifting seat 6. Clamping components are arranged on both sides of the heat sealing positions corresponding to the upper and lower heat sealing plates. Before the heat sealing process is performed, the two clamping components can clamp the substrate exposed to the heat sealing plate and keep the substrate away from each other to tighten it. Specifically, a pressure block 14 is arranged on the upper lifting seat 1, and the clamping assembly includes a lower jaw 10, on which an upper jaw 11 is swingably arranged, and the upper jaw 11 is connected to a swing arm 9, and a first spring 8 is connected between the swing arm 9 and the frame. The pressure block 14 can squeeze the upper jaw 11 to swing down and cooperate with the jaw 10 to clamp the substrate, and the lower jaw 10 is slidably arranged in the mounting groove of the mounting seat 7, and a second spring 15 for tightly pressing the lower jaw 10 is arranged in the mounting groove, and a first inclined surface 13 is arranged on the pressure block 14, and a second inclined surface 12 cooperating with the first inclined surface 13 is arranged on the upper jaw 11. Of course, in addition to the above-mentioned mechanical structure, the clamping assembly can also use a pneumatic clamping cylinder to clamp the substrate, and then set the clamping cylinder on the moving seat, and drive the moving seat to move through common linear drive structures such as cylinders, linear motors, screws, gear racks, etc., to achieve the movement of the clamping cylinder, so that after the clamping cylinder clamps the substrate, it can move to tighten the substrate, and the clamping assembly is set on the lower lifting seat 6. The lower lifting seat 6 is connected to the piston rod of the lifting drive cylinder 16, and the lifting drive cylinder 16 is set on the base. By controlling the lifting drive cylinder 16, the lower lifting seat 6 can be driven to rise and fall. The upper lifting seat 1 is driven to rise and fall by a connecting rod mechanism driven by a motor. This structure is not an innovative point of the present application, so it will not be described in detail.
[0016] The working principle of the utility model is as follows: the lower lifting seat 6 drives the lower heat sealing plate 4 to rise to the heat sealing processing height, and then the substrate passes over the lower heat sealing plate 4, and the part of the substrate exposed on the lower heat sealing plate just passes between the upper clamping jaw 11 and the lower clamping jaw 10, and then the upper lifting seat 1 is controlled to descend. During the descent of the upper lifting seat 1, the pressing block 14 will first squeeze the upper clamping jaw 11 to swing downward, clamp the substrate between the upper and lower clamping jaws, and drive the swing arm 9 to swing, stretching the first spring 8, and then as the upper lifting seat 1 continues to descend, the first inclined surface 1 on the pressing block 14 3 will cooperate with the second inclined surface 12 on the upper clamping jaw 11 to apply a force to the entire clamping jaw, so that the lower clamping jaw 10 and the upper clamping jaw 11 move in the mounting seat 7 to squeeze the second spring and move away from the heat sealing plate, so that both sides of the substrate can be clamped and tightened. Then, as the upper lifting seat 1 continues to descend, the upper heat sealing plate 3 presses the substrate against the lower heat sealing plate 4 for heat sealing processing. At this time, since the substrate has been tightened by the clamping jaws on both sides, the substrate will not shrink or deform during the heat sealing process, thereby ensuring the heat sealing quality and the aesthetics of the product after heat sealing.
[0017] The structure of the utility model effectively replaces the traditional structure of first flipping and then lifting, so that the overall lateral size of the mechanism becomes smaller, the floor space thereof is reduced, the layout is convenient, and the paper conveying efficiency is effectively improved.
