Description

Carbon ribbon box and connection structure of carbon ribbon box and printer

Technical Field

The utility model belongs to the technical field of the printer, concretely relates to carbon ribbon box and connection structure with printer thereof.

Background

Traditional industry type thermal transfer printer carbon ribbon size is big, beats printer head because regulatory function leads to bulky more, and carbon ribbon and printer head overall arrangement lead to the carbon ribbon and beat printer head relative position irregular because of complete machine size restraint and lead to the design carbon ribbon box difficulty, and the carbon ribbon is direct mount usually on the organism, if will set up the carbon ribbon box, can cause the carbon ribbon casing volume huge, assembles complicacy, processing cost of transportation height.

The conventional industrial type thermal transfer printer employs a manual installation of a ribbon supply end and a recovery end. Installation, a plurality of exhibition flat axles, beat printer head bottom need be walked around to the carbon ribbon, and the route is complicated, and the space is narrow, and the operation is complicated:

the installation method of the carbon ribbon supply end commonly used at present comprises two installation methods of elastic deformation fixing of a metal elastic sheet and expansion fixing of a mechanical structure. The metal elastic sheet is elastically deformed and fixed, the carbon ribbon needs to be aligned and inserted onto the supply end shaft, the operation of the whole process is laborious, and the elasticity of the metal elastic sheet is weakened when the service time reaches a certain stage, so that the carbon ribbon cannot be fixed. The mechanical structure expansion fixing mode needs to put in a carbon ribbon reel, and after the position is restrained, the expansion mechanism is operated by two hands to fix the carbon ribbon. The process is complex to operate and its reliability of fixation is not clearly indicated.

During the installation process, the carbon ribbon is required to be drawn to pass through the carbon ribbon flattening rods and the lower part of the printing head to reach the recovery end. Because traditional industrial type thermal transfer printer structure is complicated, beat printer head below space narrow, the carbon ribbon material itself is extremely soft, leads to pulling the easy wrong dress of process appearance, the carbon ribbon is impaired scheduling problem.

The carbon belt recovery end is installed, and two types of carbon belt recovery ends are commonly used at present. One is cored recycling, the installation of cored recycling is consistent with the supply end operation. The other type is coreless recovery, which needs two-hand operation to wind the carbon tape on a shaft and rotate for several turns to fix the carbon tape firmly. This process is complicated to operate and wastes ribbon. When the ribbon is replaced to match different types of labels, the process is very complicated, difficult to replace, and takes a long time, and the ribbon has to be debugged again after installation.

And the carbon ribbon mounting process needs to be operated reversely when the carbon ribbon is detached, and the operation process is complex and laborious. Meanwhile, an operator needs to directly contact the carbon ribbon, and hands are easily polluted. The carbon ribbon is easy to scatter, waste and pollution are caused.
