Description

Technical Field

[0001] This utility model belongs to the field of heat transfer technology, and specifically refers to a heat transfer device. Background Technology

[0002] Heat transfer printing is an emerging printing process that consists of two parts: transfer film printing and transfer processing. Transfer film printing refers to printing a pre-designed pattern onto the surface of a thin film. Transfer processing involves using a heat transfer machine to heat and pressurize the film to transfer the pattern onto a substrate, where it is organically integrated with the substrate surface.

[0003] In recent years, with technological advancements and economic prosperity, people's pursuit of product quality has become increasingly strong. Aesthetically pleasing and refined product appearance has become a key factor in purchasing decisions, leading to the continuous expansion of the domestic market for heat transfer printing technology.

[0004] However, most heat transfer printing machines currently on the market require the operator to first place the substrate onto the transfer unit of the machine, and then control the machine to complete the printing process through hand-foot coordination. This repetitive and tedious work is inefficient, cannot meet the needs of large-scale production, and also compromises safety, hindering cost control for businesses. Utility Model Content
