Colorful heat transfer printing device

Abstract

The invention relates to a colorful heat transfer printing device which comprises a shell, a first driving device, a printing device, a cross beam, a rack and a carrier, pipe shafts are fixed to the left side and the right side of the shell correspondingly, and the two pipe shafts are rotationally connected with the rack; the first driving device is mounted on the rack, and the driving end of the first driving device is in transmission connection with any one of the tubular shafts; the printing device is arranged in the shell, the two ends of the cross beam penetrate through the two tubular shafts and penetrate out of the two tubular shafts to be fixedly connected with the rack, and the printing end of the printing device faces downwards; and a plurality of ribbon cartridges are annularly arranged in the shell at intervals. The single printing head is adopted, the rotary colored tape library is configured, the colored tape with the corresponding color is directly called from the rotary colored tape library, the structure is light, the color can be changed at will, and the printing machine has the advantages of being small in size, simple in transmission, low in cost and small in printing stroke.

Description

technical field [0001] The invention relates to the field of thermal transfer printers, in particular to a multi-color thermal transfer printing device. Background technique [0002] At present, the thermal transfer multi-color multi-color printers currently on the market are specifically designed in two ways: one is designed for the assembly line, one color needs to be equipped with a printing channel, and a variety of ribbons and special print heads for each ribbon need to be configured. There is also a layer for a ribbon used in thermal transfer printers, which includes a plurality of colors arranged sequentially in fixed lengths along the length direction. [0003] Among the existing technologies, most printers adopt a multi-print head and multi-ribbon solution. This design is bulky, and the cost of electronic components is extremely high. In addition, the long printing channel makes it difficult to control the accuracy of printing color registration. Although the multi...

Problems solved by technology

[0003] Among the existing technologies, most printers adopt multi-print head and multi-ribbon solutions. This design is bulky, and the cost of electronic components is extremely high. In addition, the long printing channel makes it difficult to control the accuracy of printing color registration.

Although the multi-color ribbon solution can print multiple colors, there are problems such as toning printing, ribbon waste, and the inability to flexibly change the printing order.
