It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] Example 1.

The template 43 is horizontally arranged inside the mounting frame 2, the reset spring 44 is arranged in the mounting frame 2, and the two ends of the reset spring 44 are respectively connected to the lower template 43 and the body 1, so that the lower template 43 can compress the reset spring 44 and move relative to the mounting frame 2 under the pressure of the upper template 42; the covering mechanism 5 is provided with multiple along the circumference of the mounting frame 2, each covering mechanism 5 includes a second driving mechanism 51 and a slider 52 fixedly connected to the power output end of the second driving mechanism 51, the top of the mounting frame 2 has a guide sliding surface 22, and the slider 52 has a folding surface 521 that slides with the guide sliding surface 22.

[0026] When working, Figure 5 As shown, the lower template 43 is in the initial state. Under the action of the return spring 44, its upper plate surface is flush with the guide slide surface 22. Then, the trunk cover 100 to be hemmed is placed on the lower template 43, so that the edge hemming fabric 200 of the trunk cover 100 to be hemmed is evenly spread on the guide slide surface 22, and then the glue spraying mechanism 3 is started to spray glue. In this embodiment, as shown in FIG. Figure 1 As shown, the glue spraying mechanism 3 uses a mechanical arm to drive the glue spraying nozzle for spraying, and in this embodiment, the glue spraying mechanism 3 sprays the PUR glue of the glue model PK-9823B2, and the spraying temperature is 150-155 degrees in summer and 165-70 degrees in winter, and the glue spraying amount is 120-150 grams / square, ensuring that the glue is evenly and accurately coated on the hemming area of ​​the trunk cover 100; then, the upper template 42 is driven downward by the first driving mechanism 41, so that the trunk cover 100 is pressed against the lower template 43. In the specific implementation, the first driving mechanism 41 is a cylinder, until the upper plate surface of the trunk cover 100 is flush with the guide sliding surface 22. In this process, the extrusion surface 21 cooperates with the outer side wall of the trunk cover 100 to clamp the hemming fabric 200, fold its edge and fix it, the pressure is 0.6-0.75MPa, and the shaping lasts for 3-5 seconds; then, as Figure 4 As shown, the second driving mechanism 51 drives the slider 52 to move, the slider 52 contacts the edge fabric 200, and the edge fabric 200 is clamped by the folding surface 521 and the upper plate surface of the trunk cover 100, and the folding surface 521 pushes along the inner side of the guide surface 22, as shown in FIG. Figure 6 and Figure 7 As shown, the hemming fabric 200 is gradually tightened and fixed until it is completely covered on the trunk cover 100, and the shaping and pressure are maintained for 15-20 seconds to ensure a firm bond; finally, the first drive mechanism 41 drives the upper template 42 to move upward, and the reset spring 44 loses its pressure, so that the lower template 43 continues to press the hemming area of ​​the trunk cover 100 under the elastic action of the reset spring 44, ensuring that the trunk cover 100 and the hemming fabric 200 are tightly combined. In summary, the entire workflow realizes the automation and precision of the hemming process of the trunk cover 100, ensures the efficiency and consistency of the hemming, reduces the proportion of manual operations, reduces the interference of human factors on the process, enhances the flexibility and adaptability of the tooling, and meets the hemming requirements of different materials and products.

[0029] In this embodiment, if Figure 3 As shown, in order for the slider 52 to move in a stable manner, the covering mechanism 5 further includes a guide rail 53 and a slide seat 54, wherein the guide rail 53 is fixedly connected to the body 1 by bolts, the slide seat 54 is fixedly connected to the slider 52 by bolts, and the slider 52 is slidably matched with the guide rail 53 through the slide seat 54. In this embodiment, the design of the covering mechanism 5 is further optimized, the guide rail 53 is fixedly connected to the body 1 by bolts, and the slide seat 54 is connected to the slider 52 by bolts, so that the slider 52 can move stably on the guide rail 53. This design ensures that the slider 52 slides smoothly along the guide rail 53, providing a more stable operating environment for the hemming of the trunk cover.

[0030] In this embodiment, if Figure 3 As shown, for the convenience of maintenance, the second driving mechanism 51 is a cylinder, and a T-shaped connecting block 55 is fixedly connected to the output shaft of the second driving mechanism. The slider 52 is provided with a T-shaped groove 523 adapted to the T-shaped connecting block 55, and the T-shaped connecting block 55 is fixedly connected to the slider 52 through the T-shaped groove 523. With this structural design, the slider 52 is designed with a T-shaped groove 523 that matches the T-shaped connecting block 55 to ensure that the T-shaped connecting block 55 can be firmly fixed on the slider 52, and according to the requirements of the hemming of the luggage cover of different specifications, the T-shaped connecting block 55 is connected with the T-shaped groove 523, so that the slider 52 can be replaced more quickly, thereby realizing fast and effective equipment adjustment.

[0031] In this embodiment, if Figure 1 and Figure 2As shown, in order to ensure stable pressure transmission, the pressing mechanism 4 also includes a guide slide 45, a pressure plate 46 and a connecting column 47. The first driving mechanism 41 is a cylinder fixedly connected to the guide slide 45. The guide slide 45 has a plurality of guide slide columns 48 parallel to the axis of the output shaft of the first driving mechanism 41. The pressure plate 46 is fixedly connected to the output shaft of the first driving mechanism 41, and a plurality of sleeves 49 slidingly matched with the guide slide columns 48 are provided on the pressure plate 46. The upper template 42 is fixedly connected to the side of the pressure plate 46 opposite to the first driving mechanism 41 through the connecting column 47, and a plurality of connecting columns 47 are evenly spaced on the plate surface of the upper template 42. In this way, with the guide slide 45 as the support, the first driving mechanism 41 adopts a cylinder to drive the pressure plate 46, the pressure plate 46 slides with the guide slide column 48 through the shaft sleeve 49, and the upper template 42 is connected to the pressure plate 46 through the connecting column 47. This connection method ensures that during the process of pressing the edge of the trunk cover, the pressure can be evenly and stably transmitted to the required area through the upper template 42, thereby improving the consistency of the pressing effect.

[0032] In this embodiment, if Figure 1 As shown, in order to prevent excessive movement of the pressing plate 46, the lower plate surface of the pressing plate 46 and the machine body 1 are respectively provided with relatively arranged limiting posts 7. By providing the limiting posts 7, the pressing plate 46 can be effectively prevented from excessive movement during the pressing process, ensuring that the pressing plate 46 does not exceed the required range during operation, and avoiding additional pressing or unnecessary movement.

[0033] In this embodiment, if Figure 2 and Figure 7 As shown, in order to make the pressing process more stable, the body 1 is provided with a spring seat 9 and a through hole 8 connected to the inside of the mounting frame 2. The spring seat 9 is fixedly connected to the body 1 by bolts and is located below the through hole 8 in the axial direction. The end of the spring opposite to the lower template 43 is fixedly connected to the spring seat 9. In this embodiment, the setting of the spring seat 9, on the one hand, can facilitate the installation of the reset spring 44, and on the other hand, can provide sufficient deformation space for the reset spring 44 in conjunction with the through hole 8, ensuring that the reset spring 44 will not be restricted during operation and can be deformed according to the design requirements. The through hole 8 also connects the internal space of the mounting frame 2 with the external space, so that the air generated during the pressing process of the lower template 43 can flow out smoothly, avoiding the situation that the poor exhaust may cause uneven hemming results or defects.
