[0020] Embodiment 1

[0021] As Figure 1-3 shown, a double-sided embossing device for PVC film includes a base 1, a film feeding roller 2, an embossing box 3, and a film winding roller 10 arranged on the upper part of the base 1. Two groups of embossing components are evenly arranged in the embossing box 3 along the conveying direction of the PVC film. The embossing components are composed of two conveying rollers 4 symmetrically arranged up and down. A heating module 5 and a cooling module 6 are arranged at intervals on the outer side of the conveying roller 4, and the heating module 5 arranged on the upper conveying roller 4 is aligned with the cooling module 6 arranged on the lower conveying roller 4. A pattern plate 7 for embossing is arranged outside the heating module 5, and a holding plate 8 for cooling and solidifying the pattern of the PVC film is arranged outside the cooling module 6. The pattern plate 7 is heated by the heating module 5, and the holding plate 8 is cooled by the cooling module 6 at the same time. When the upper and lower conveying rollers 4 convey the PVC film, one side of the PVC film is hot-pressed and formed, and at the same time, the formed pattern is cooled and shaped, and it is avoided that the PVC film becomes soft due to hot pressing, resulting in deformation and damage of the formed pattern during the conveying process.

[0022] And the distance between adjacent two groups of embossing components is set to an odd multiple of the outer contour length of the pattern plate 7. A driving mechanism 9 for driving the embossing components to feed synchronously is arranged outside the embossing box 3, so that the upper and lower sides of the PVC film are embossed after being squeezed and conveyed by the two groups of embossing components.

[0023] Installation grooves are evenly opened on the outer side of the conveying roller 4, and a heat insulation box 12 is arranged in the installation grooves to prevent the heat generated by the heating module 5 from interfering with the cooling module 6.

[0024] A heat insulation sheet 13 movably connected to the conveying roller 4 is arranged between the adjacent pattern plate 7 and the holding plate 8, which avoids the mutual interference of heat between the adjacent pattern plate 7 and the holding plate 8.

[0025] Embodiment 2

[0026] As Figure 4As shown in the figure, the conveying roller 4 of the present disclosure includes a transmission shaft 40, a separating sleeve 41, and a support bar 42. The transmission shaft 40 is rotatably arranged in the embossing box 3. A separating sleeve 41 is sleeved outside the transmission shaft 40, and a support bar 42 is movably arranged outside the separating sleeve 41, making the conveying roller 4 convenient for later disassembly, inspection, and maintenance.

[0027] As Figure 5 shown, a connection method of the heat insulation sheet 13 of the present disclosure is that the cross-section of the heat insulation sheet 13 is set in a wedge shape, and the side of the heat insulation sheet 13 close to the separating sleeve 41 is set as a T-shaped connecting bar 11. The separating sleeve 41 is provided with a chute matching the T-shaped connecting bar 11. The heat insulation sheet 13 is connected and combined with the separating sleeve 41 through the T-shaped connecting bar 11, and the heat insulation sheet 13 is used to squeeze the pattern plates 7 and the holding plates 8 on both sides. Finally, the pattern plates 7 and the holding plates 8 form a cylindrical embossing sleeve.

[0028] As Figure 6 shown, another connection method of the heat insulation sheet 13 of the present disclosure is that the T-shaped connecting bars 11 are evenly arranged on the sides of the heat insulation sheet 13 close to the separating sleeve 41, the pattern plates 7, and the holding plates 8. The separating sleeve 41, the pattern plates 7, and the holding plates 8 are respectively provided with chutes matching the T-shaped connecting bars 11. The separating sleeve 41, the pattern plates 7, and the holding plates 8 are quickly connected and combined through the T-shaped connecting bars 11.

[0029] Working principle: During operation, the heating module 5 is used to heat the pattern plate 7, and at the same time, the cooling module 6 is used to cool the holding plate 8. When the upper and lower conveying rollers 4 convey the PVC film, one side of the PVC film is hot-pressed and formed, and at the same time, the pattern formed by the hot pressing is cooled and shaped. Moreover, it is avoided that the PVC film becomes soft due to hot pressing, resulting in deformation and damage of the formed pattern during the conveying process. At the same time, the distance between adjacent two sets of embossing components is set to an odd multiple of the outer contour length of the pattern plate 7, so that both sides of the PVC film are embossed after being squeezed and conveyed by the two sets of embossing components.
