Ornament attaching structure and method

Abstract

The invention discloses an ornament attaching method. The ornament attaching method comprises the following steps that high-temperature-resisting plastics are attached to one face of TPU or PVC, and high-temperature hot melting glue is attached to the other face of TPU or PVC; on a die, the high frequency is adopted for conducting hot pressing on the high-temperature-resisting plastics in the first step, the surplus high-temperature hot melting glue it torn off, and an ornament attached body with patterns is obtained; the ornament attached body is placed to the position above an attached unitand aligned with the die, high-frequency heating of the ornament attached body is conducted, and then the ornament attached body is subjected to hot pressing to the attached unit; and cooling is conducted to the room temperature, the surplus high-temperature-resisting plastics are torn off, and a firm ornament is pasted to the attached unit. According to the ornament attaching structure and method, design is scientific and reasonable, and the following effects that high-temperature-resisting film protection is adopted, integral patterns are attractive, the ornament attached body does not leavemarks on the die, and meanwhile the patterns with better third dimensions can be formed. Fusion with most of materials can be achieved, transition of adhesiveness of two different materials can be achieved, the bonding firmness is improved, and adaptability is wider.

Description

technical field [0001] The invention relates to the technical field of case and bag manufacturing, in particular to a structure and method for laminating decorations with beautiful patterns, firm and non-falling off, and simple operation. Background technique [0002] High-frequency waves are high-frequency waves. High-frequency waves refer to electromagnetic waves with a frequency greater than 100Khz. The welding and welding principles of high-frequency waves are also different from ultrasonic waves. High-frequency waves use high-frequency electromagnetic fields to make the internal molecules of materials collide violently with each other to generate high temperatures to achieve the purpose of welding and welding. The ultrasonic wave uses the principle of frictional heat generation to generate a large amount of heat to achieve the purpose of welding and welding. High frequency has a wide range of applications, so there are high frequency plastic welding machines, high frequ...

Problems solved by technology

[0004] But this method obtains decorative sheet and there is following problem: the first needs the surface treatment of pasted unit (with laser the thin film 2 on the surface of the loose leather 1 is removed); the second does not consider the shrinkage rate between different materials, The bonding and bonding are not firm; the third is that the outside of the high-frequency mold is easy to burn the surface of the pasted unit, resulting in delamination at the junction, which is easy to fall off after use and burying hidden dangers; fourth, the surface is reshaped by the mold, and individual patterns on the surface will appear incorrectly. beautiful

It is most similar to the present invention, but there are substantial differences: 1. Same as the combination structure of the above-mentioned engraved leather and decorative pieces, the shrinkage rate between different materials is not considered, resulting in weak bonding and bonding; 2. Punching is required; 3. The outside of the high-frequency mold is easy to burn the surface of the pasted unit, resulting in delamination at the junction, which is easy to fall off after use, burying hidden dangers; 4. Through the surface shaping of the mold, some unsightly patterns will appear on the surface
