Description
Technical Field
[0001] The utility model relates to the field of hot stamping decorative strips, in particular to a hot stamping decorative strip structure and a hot stamping device for automobile interior decoration. Background Art
[0002] Hot stamping is commonly known as "hot stamping". The essence of hot stamping is transfer printing. It is a process in which the adhesive layer on the hot stamping mold is melted by heat to produce adhesion with the surface of the substrate, and the carrier film and the hot stamping layer are peeled off after cooling, leaving the hot stamping layer to be retained on the surface of the substrate. With the development of automobile interiors, the embracing cockpit atmosphere has become the mainstream of the market, so the curvature of the A side of the trim strip is getting larger and larger, and the existing trim strip shape cannot meet market demand. Summary of the invention
[0003] The embodiment of the present application provides a rolling decorative strip structure and a rolling device for automobile interior. The decorative strip structure has a height difference between the first strip member and the second strip member, and the first strip member and the second strip member are transitioned through an arc strip member. The transition is smooth, which meets market demand and is convenient for subsequent hot stamping by a rolling device.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rolling decorative strip structure for automobile interior, the decorative strip comprising a first strip piece, a second strip piece, an arc strip piece, and a boss, there is a height difference between the first strip piece and the second strip piece and the transition is made through the arc strip piece, and the boss is arranged at the upper ends of the first strip piece, the second strip piece, and the arc strip piece.
[0005] Compared with the prior art, the advantages of the utility model are:
[0006] In response to the needs of the existing market, a decorative strip structure with a height difference is provided. Due to the height difference between the first strip member and the second strip member, the first strip member and the second strip member are transitioned through an arc strip member, and the transition is smooth, which meets market demand and facilitates subsequent hot stamping.
[0007] As an improvement, the ratio of the height difference between the first strip and the second strip to the length difference between the tail end of the first strip and the tail end of the second strip is not greater than 0.4, so that the contact surface of the roller in the hot stamping process is as horizontal as possible, and the applied hot stamping force is decomposed as much as possible on the horizontal plane, which can ensure the adhesion requirements of the hot stamping.
[0008] As an improvement, the upper end surface of the boss and the side wall are transitioned through rounded corners, and the rounded corner transition ensures the flatness of the edge of the hot stamping film cut by the hot stamping roller.
[0009] As an improvement, the upper end surface of the boss is arranged parallel to the horizontal plane or at an angle of less than 5°, so that the upper end surface of the boss is evenly stressed during hot stamping, thereby improving the bonding force between the adhesive layer and the upper end surface of the boss.
[0010] A rolling device adopts any one of the above-mentioned rolling decorative strip structures for automobile interior, the upper end surface of the boss is hot-stamped by the rolling device, the rolling device includes a roller, a mounting seat, and a hot-stamping film, the decorative strip is installed on the upper end of the mounting seat, the roller is arranged above the decorative strip, the roller is provided with a concave printing surface along the circumference, the concave printing surface is arranged corresponding to the boss, and the hot-stamping film is arranged between the concave printing surface and the boss.
[0011] Compared with the prior art, the advantages of the utility model are:
[0012] The hot stamping film is hot stamped on the upper end surface of the boss by abutting the lower end surface of the concave printing surface against the upper end surface of the boss.
[0013] As an improvement, the hot rolling device also includes a contour seat and a contour ring. The contour ring is arranged on one side of the roller and coaxially with the roller. The contour seat is arranged corresponding to the contour ring. The upper end face of the contour seat is consistent in shape with the upper end face of the boss. The upper end face of the contour seat is consistent in shape with the upper end face of the boss. When the gravure surface rolls on the upper end face of the boss, the contour ring rolls on the upper end face of the contour seat, thereby guiding the up and down movement of the roller.
