Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of transfer printing device, especially relates to a transfer printing device for color card production. BACKGROUND

[0002] The existing transfer printing device sometimes appears uneven phenomenon in the color card transfer printing process, and the problem mainly shows as the local peeling of pattern, color distortion or texture inconsistency, which seriously affects the appearance and quality of the product. When the transfer printing device is operated, if the applied pressure is not uniform, the transfer printing effect of some areas can be inferior to other areas, thereby causing the transfer printing pattern to appear blank or blurred.

[0003] The conventional response method for uneven transfer mainly includes enhancing pressure and temperature control, optimizing the design of heating equipment and improving the operation standard in the production process. However, these response measures are not defect-free. When a more precise pressure and temperature control system is introduced, the complexity and cost of the equipment will inevitably increase, which may lead to an increase in equipment failure rate and difficulty in maintenance and operation. At the same time, although optimizing the design of the heating equipment can improve the transfer uniformity, it may introduce new energy consumption problems and increase the operating cost. Therefore, we hope to design a transfer printing device with a novel structure to solve this problem. UTILITY MODEL CONTENT
