Description

Technical Field

[0001] The utility model specifically relates to a PVC tablecloth gilding device. Background Technique

[0002] Gilding, also known as hot stamping, is a printing and decoration process in which a metal printing plate is heated, foil is applied, and golden characters or patterns are stamped on printed matter. With the rapid development of hot stamping foil and the packaging industry, the application of electrothermal aluminum gilding is becoming more and more widespread. Gilding has the characteristics of clear and beautiful patterns, bright and eye-catching colors, wear resistance and weather resistance. The gilding process used in the field of tablecloths is also becoming more and more frequent.

[0003] The existing tablecloth gilding device has the following problems: during the hot stamping process, because the fabric is relatively soft, folding and bending will occur when the winding roller pulls the fabric, which will block the hot stamping, and the hot stamping cannot reach the working state, resulting in incomplete patterns or even the tablecloth cannot be used, thus affecting the printing efficiency and quality of the tablecloth.
