Problems solved by technology

However, the current TPU film-coated decorative tape is made by traditional film-coating technology, and the stability of the finished product is poor. Under the condition of external force, especially torsion, it is easy to cause the film and decorative tape to separate and fall off, thus restricting the TPU film.

Embodiment Construction

[0025] In this example, refer to figure 1 , the production process of the TPU film-coated decorative tape is carried out in the following steps,

[0026] 1) Preheat the decorative tape through the heating device 1, and the preheating temperature is 200-230°C;

[0027] 2) Vacuum the laminating head 2 through the vacuum negative pressure device 4, then transport the preheated decorative tape to the vacuum environment in the laminating head 2, and add TPU rubber to the laminating head 2 at the same time ;

[0028] 3) Through the control of the laminating machine 3, the TPU rubber material flows along the flow channel to the mold sleeve located in the laminating head 2 after equalizing the pressure in the flow channel of the laminating head 2;

[0029] 4) After the decorative tape passes through the mold sleeve, the TPU rubber material is combined with the decorative tape through the negative pressure in the mold sleeve;

[0030] 5) After the decorative belt is combined with th...

Abstract

The invention discloses a production process and device for a TPU laminating ornamental band. The device comprises a laminating handpiece and a laminating machine, and the laminating handpiece is internally provided with a die sleeve and a pressure die; the front end of the die sleeve is provided with a die sleeve hole for the ornamental band to penetrate, and a flow channel extends to the front end of the exterior of the die sleeve; and the interior of the laminating handpiece is vacuumized; and the pressure die is arranged dead ahead the die sleeve, and internally provided with a forming hole. According to the production process and device, the ornamental band is preheated at high temperature, and the degree of bonding between the preheated ornamental band and TPU glue can be improved; then, the bonding between the TPU glue and the ornamental band is accelerated and promoted through vacuum negative pressure creatively, and the TPU glue and the ornamental band are formed through the pressure die after the TPU glue and the ornamental band are combined completely; in this way, a TPU film and the ornamental band can be combined stably; and the ornamental band can not fall off in useeven though the ornamental band is subjected to larger torsion, so that the product quality is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of clothing accessories, in particular to a production process and production device of a film-coated decorative belt. Background technique [0002] Some decorative belts are often used as accessories in clothing, bags, shoes and other products, and their functions mainly include decoration, embellishment, and trademarking. The existing decorative tapes in the market are various and widely used, but the traditional decorative tapes are of unsatisfactory quality, not beautiful, and it is not easy to make patterned trademarks on them. At present, the decorative tapes with film coating are more attractive to consumers. Among them, the decorative effect of TPU film-coated decorative tapes is the most prominent, so it is an ideal decorative tape product at present. However, the current TPU film-coated decorative tape is made by traditional film-coating technology, and the stability of the finished product is poo...
