Description

Technical Field

[0002] As we all know, roller thermal transfer equipment is a device used for thermal transfer on different materials. It usually consists of a roller and a heating element. During use, the pattern or text to be transferred is first printed on the thermal transfer paper. Then, the thermal transfer paper and the material to be transferred (such as textiles, ceramics, plastics, etc.) are placed under the roller, and the roller will rotate to bring the thermal transfer paper into close contact with the material;

[0003] The advantage of roller thermal transfer equipment is that it can perform efficient thermal transfer on large areas or continuous materials. It is suitable for large-scale production, such as textile printing, ceramic tile production, etc. In addition, roller thermal transfer equipment can also achieve multi-color transfer, making the pattern more rich and diverse.

[0004] However, the existing roller-type thermal transfer equipment also has certain shortcomings. First, when the existing roller-type thermal transfer equipment uses a heating roller to transfer the thermal transfer paper, due to the limited disassembly and assembly space between the machine body and the heating roller, when the heating tube needs to be repaired, the machine body, driving parts, heating roller and other structural parts need to be fully disassembled, which is obviously inconvenient to use;

[0005] Secondly, the existing roller-type thermal transfer equipment mostly simply uses natural ventilation to dissipate heat from the electrical components inside the machine body. Since the heat dissipation efficiency of natural ventilation is poor, it is easy to cause the problem of untimely heat dissipation of the electrical components. Utility Model Content
