Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of thermal sublimation transfer paper, and specifically relates to a thermal sublimation transfer paper with anti-static effect and a roller assembly. BACKGROUND

[0002] Thermal sublimation transfer is to print images (such as portraits, landscapes, and texts) on special inkjet paper in a mirror image manner through an inkjet transfer machine equipped with thermal sublimation transfer ink. Subsequently, these printed images are heated to about 200°C through a thermal transfer device, causing the thermal transfer ink on the thermal sublimation paper to sublimate and penetrate onto the printing material (such as textiles, porcelain cups, porcelain plates, porcelain boards, and metals), thereby achieving realistic transfer of color images. This is a new technology that allows for personalized customization. Anti-static performance is an important indicator of thermal sublimation paper, as lower surface resistance will help effectively eliminate static electricity and prevent paper from sticking together or to the printed product due to static electricity, thereby affecting the transfer quality. Existing thermal sublimation paper generally has poor anti-static performance, which has caused many problems in practical applications, such as reduced transfer quality and easy indentation of paper boxes during transportation.

[0003] The patent with patent publication number CN214822047U describes a thermal sublimation transfer paper with anti-static function, which includes a winding drum, a transfer paper body, a machine-mounted roller, and an anti-collision end cover. The transfer paper body is installed in a paper tube shape on the winding drum, the machine-mounted roller is fitted on both ends of the winding drum, and the anti-collision end cover is threadedly connected to the machine-mounted roller and covers both ends of the transfer paper body. Through a specific process, butyl rubber latex is mixed with aluminum hydroxide and then applied as an anti-warping coating on the transfer paper body. The main purpose of this coating is to reduce the degree of paper warping when it comes into contact with water, thereby achieving anti-warping effect. In addition to the anti-warping coating, a polythiophene film anti-static layer is also applied on the transfer paper.

[0004] However, this device has some drawbacks when in use. Although the application of an anti-static layer on the transfer paper body can prevent the generation of static electricity in most scenarios such as storage and transfer of the transfer paper, the presence of electric charges in the human body and transfer machine can significantly affect the anti-static effect of the transfer paper after contact with the transfer paper.

[0005] Therefore, the present application provides a thermal sublimation transfer paper with anti-static effect and a roller assembly to eliminate the drawbacks of existing devices. SUMMARY
