Vacuum thermal transfer device for sheet materials

Abstract

1 Abstract The present invention discloses a vacuum thermal transfer device for sheet materials comprising a frame, a vacuum pump unit, a heat-conducting box and a transfer assembly, wherein the frame is provided with lifting driving mechanisms, at least one heating mechanism, at least one conveying mechanism, a first heating mechanism, and a second heating mechanism; the first heating mechanism is provided above a heat-conducting conveyor belt of the conveying mechanism and the heat-conducting conveyor belt of the conveying mechanism is arranged to be in contact with at least one heating surface of the second heating mechanism provided below the heat-conducting conveyor belt; the heat-conducting box is positioned on the heat-conducting conveyor belt, the transfer assembly is covered over the heat-conducting box to enclose and form a sealed heating chamber, at least one sheet material to be processed that is jacked up is arranged in the sealed heating chamber, and a transfer member in the transfer assembly is positioned above the sheet material to be processed; the lifting driving mechanisms are connected to the first heating mechanism for driving the first heating mechanism to move and abut against the transfer assembly; at least one side of the heat-conducting box is provided with vacuum pipes connected to the sealed heating chamber, and the vacuum pipes are connected to the vacuum pump unit through a pipeline. The present invention enables the transfer of patterns or designs on a plurality of surfaces of the sheet materials to be processed, allowing sheet materials aesthetically pleasing.
