Description

Mounting structure and printer of carbon ribbon box and printer body
Technical Field
The invention belongs to the technical field of printers, and particularly relates to a mounting structure of a carbon ribbon cartridge and a printer body and a printer.
Background
The traditional industrial thermal transfer printer carbon ribbon supply end mounting structure comprises two types of metal elastic sheet elastic deformation fixation and mechanical structure expansion fixation. The metal elastic sheet elastic deformation fixing mode needs to be laborious to insert the carbon ribbon into the supply end shaft, the operation of the whole process is laborious, the service time and the times of the metal elastic sheet reach a certain stage, the elasticity is weakened, and the condition that the carbon ribbon cannot be fixed can be caused. 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.
There are two forms of carbon tape recovery end commonly used. 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. The carbon ribbon supply end and the carbon ribbon recovery end are installed in a manner that an operator subjectively judges the position of the carbon ribbon, the problem of improper installation is easily caused, and the installation stage cannot be effectively monitored.
Existing carbon tape cartridges are roughly classified into two types according to the fit relationship between a carbon tape shaft and a housing: the first type is that the carbon ribbon shaft is completely restrained by the shell, after the carbon ribbon box is arranged in the machine, the machine only assembles and restrains the carbon ribbon box, and power is provided for the carbon ribbon shaft through gears and the like. The second type is that the carbon ribbon axle part is retrained by the casing, and after the carbon ribbon box was packed into the machine, the machine was assembled the restraint to the carbon ribbon box, and the casing passes through elastomeric element extrusion carbon ribbon axle, realizes carbon ribbon axle's complete restraint.
The carbon ribbon box of the traditional small-sized thermal transfer printer is directly placed in the carbon ribbon box after being connected with the machine body, the carbon ribbon box is limited through structural characteristics on the machine body, and the locking mechanism locks the carbon ribbon box. The casings of the carbon tape boxes with the two modes are all involved in carbon tape limiting, contact is kept in the rotating process of the carbon tape, and the problems that the carbon tape is wrinkled, the casings are abraded, parts are separated from each other, noise is generated and the like are caused to the rotating stability of the carbon tape inevitably, so that printing quality interference is caused. Because of frequent contact friction, the carbon tape cartridge has strict requirements on the material of the cartridge case, and the material with high requirements on wear resistance and strength is required, which causes the cost of the case to rise. Meanwhile, the carbon ribbon is limited and restricted by the shell, and the requirement on the size precision of the shell is high.
Because of the above problems, the existing carbon tape cartridge is only suitable for low-speed, small-sized machines. The existing high-speed and large-scale machine type carbon-free tape box. If the large-scale printer adopts the traditional carbon tape box, the shell contacts the carbon tape in the high-speed printing process, and the problems of jitter, abrasion, noise and the like can be caused to interfere with the printing quality.
