Problems solved by technology

[0004] 1. The processing equipment has many parts, complex structure, takes up a lot of space, and is not compact enough
[0005] 2. The technical requirements for the manufacture of this equipment are relatively high. Since the positional relationship of the tension adjustment components on the equipment is more important, if you want to obtain a relatively stable tension force, the ribbon guide and elastic parts and other linkage mechanisms Installation requires relatively high assembly technology, which greatly increases production costs

Abstract

The invention discloses a color belt tensioning mechanism of an intelligent card lithoprint device. The color belt tensioning mechanism comprises a coil spring and a rotating control mechanism fixedly connected with the coil spring; and the rotating control mechanism comprises a rotating connecting cylinder and a tensioning control assembly for limiting a color belt. The rotating connecting cylinder is internally provided with a fixed sleeve; the fixed sleeve is coaxially arranged outside a winding and unwinding driving shaft of the color belt; the rotating connecting cylinder is rotatably connected to the fixed sleeve; the tensioning control assembly is fixedly connected to the rotating connecting cylinder; and the inner end of the coil spring is fixedly connected to the fixed sleeve, and the outer end of the coil spring is fixedly connected with the rotating connecting cylinder. The color belt tensioning mechanism is simple in structure, low in production technology requirement, and easy to assemble, and the tension force of the color belt can be kept to be constant.

Description

technical field [0001] The invention relates to a smart card production device, in particular to a ribbon tensioning mechanism of a smart card flat printing device. Background technique [0002] During the production process of the smart card, it is usually necessary to print relevant information (such as characters, patterns, etc.) on the card surface by flat printing. The lithographic printing process is realized by a lithographic printing device, which mainly includes a ribbon conveying mechanism, a card conveying mechanism and a lithographic printing mechanism, wherein the lithographic printing mechanism includes a lithographic printing head. The ribbon conveying mechanism is used to convey the ribbon to the printing head, and the card conveying mechanism is used to convey the card to be printed to the bottom of the printing head. When working, the card conveying mechanism will convey the card to be flat-printed to the bottom of the flat printing head, and the ribbon co...
