Thermal transfer device

Abstract

The invention discloses a thermal transfer device which comprises a conveyor belt, wherein a first fixed seat and a second fixed seat are installed on two sides of the conveyor belt, an upper heating roller and a middle heating roller which are coaxially arranged are installed on the first fixed seat, a lower heating roller corresponding to the upper heating roller and the middle heating roller in position is installed on the second fixed seat, and the upper heating roller, the middle heating roller and the lower heating roller are positioned at different altitudes in the same plane. The thermal transfer device solves the problem of low thermal transfer efficiency in the prior art, achieves the purpose of simultaneously performing thermal transfer to the upper part, the middle part and the lower part of the whole steel barrel by installing the two-face three-channel thermal transfer device on two sides of the conveyor belt, and further finishes the thermal transfer of the whole barrel body at the same station, thereby not only simplifying the production process and improving the production efficiency, but also avoiding the quality problem of thermal transfer at different stations due to the height error and ensuring the product quality.

Description

technical field [0001] The invention relates to a thermal transfer printing device, in particular to a double-sided three-pass thermal transfer device. Background technique [0002] The thermal transfer printing process is applied to the surface of various ABS, PP, plastic, wood, coated metal and other products. Heat transfer film can be designed and produced according to customer requirements, and the pattern can be transferred to the surface of the workpiece by hot pressing to improve product quality. In the production of steel drums, it is usually required to print various patterns on the body of the steel drum, which are located at different heights of the barrel body. The existing method is to heat the patterns of different heights separately through multiple processes. Transfer printing is not only low in production efficiency, but also easily causes printing deviation, which affects the final quality of the product.
