Description

Technical Field

[0001] The present invention relates to the technical field of inflatable surfboard production, and in particular to a high-temperature hot-melt edge sealing process and equipment for inflatable surfboards. Background Art

[0002] Existing technologies such as Figure 1 As shown, the first layer of mesh cloth needs to be fixed on the surface layer of the inflatable surfboard by glue, and then the second layer of mesh cloth needs to be fixed on the outside of the first layer of mesh cloth to perform secondary sealing on the inflatable surfboard.

[0003] In the prior art, for example, patent publication number CN215359947U discloses a roller edge sealer for inflatable surfboards. By designing a first roller, a second roller, a work surface, and a heating device structure with a specific connection relationship, the roller edge sealer is particularly suitable for laminating the curved portion of the surface layer of an inflatable surfboard. This replaces the traditional method of repeatedly scraping glue with a handheld spatula. Specifically for laminating the curved portion of the surface layer of an inflatable surfboard, a height adjustment mechanism is provided to adjust the distance between the first roller and the second roller to an appropriate value as needed. This allows the glued portion to pass smoothly through the gap between the first roller and the second roller, while also achieving the effect of pressing and sealing the edge.

[0004] The prior art has the following problems:
