Description
Technical Field
The invention belongs to the technical field of printers, and particularly relates to a mounting structure of a carbon tape box and a printer body and a printer.
Background
The traditional industrial thermal transfer printer carbon ribbon supply end mounting structure has two kinds of elastic deformation fixing of metal spring plates and expansion fixing of mechanical structures. The metal elastic sheet elastic deformation fixing mode requires laborious insertion of the carbon ribbon into the supply end shaft, the whole process operation is laborious, the service time and the times of the metal elastic sheet reach a certain stage, the elasticity is weakened, and the situation that the carbon ribbon cannot be fixed can be possibly caused. The mechanical structure is expanded and fixed in a mode that a carbon ribbon reel is needed to be put in, 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, while its fixing reliability is not explicitly indicated.
There are two forms of commonly used carbon ribbon recovery ends. One is cored recovery, which is installed in a manner consistent with the supply end operation. The other is coreless recovery, which requires two hands to wind the carbon ribbon onto the shaft and rotate for several turns to fix firmly. This process is complex to operate and wastes carbon tape. The mode of installing the carbon ribbon at the carbon ribbon supply end and the carbon ribbon recovery end is that an operator subjectively judges the position of the carbon ribbon, the problem that the carbon ribbon is not installed in place easily occurs, and the carbon ribbon cannot be effectively monitored in the installation stage.
The existing carbon ribbon boxes are roughly divided into two types according to the matching relation between a carbon ribbon shaft and a shell: the first is that the carbon ribbon shaft is completely constrained by the housing, and after the carbon ribbon cartridge is put into the machine, the machine only performs assembly constraint on the carbon ribbon cartridge, and power is supplied to the carbon ribbon shaft through gears and the like. The second type is that the carbon ribbon shaft is restrained by a shell, after the carbon ribbon cartridge is packaged in a machine, the machine is used for assembling and restraining the carbon ribbon cartridge, and the shell extrudes the carbon ribbon shaft through an elastic part to realize complete restraint of the carbon ribbon shaft.
The connection between the carbon ribbon box and the machine body of the traditional small thermal transfer printer is realized by directly placing the carbon ribbon box, limiting the carbon ribbon box through the structural characteristics on the machine body and locking the carbon ribbon box by a locking mechanism. The shell of the two-way carbon ribbon box participates in limiting of the carbon ribbon, and is kept in contact in the rotating process of the carbon ribbon, and the problems of wrinkling of the carbon ribbon, abrasion of the shell, separation of parts, noise emission and the like are caused by the unavoidable interference to the rotating stability of the carbon ribbon, so that the printing quality interference is caused. Because of frequent contact friction, strict requirements are imposed on the shell material of the carbon ribbon cartridge, and materials with high wear resistance and high strength are required, so that the shell cost is increased. Meanwhile, the carbon belt is limited and restrained by the shell, and the requirement on the dimensional accuracy of the shell is high.
Because of the above problems, existing carbon ribbon cartridges are only adaptable for low speed, small machine use. The existing high-speed large-sized machine type carbonless tape box. If the large printer adopts the traditional carbon tape box, the shell contacts the carbon tape in the high-speed printing process, and the problems of shaking, abrasion, noise and the like can be caused to disturb the printing quality.

When the housing 20 is also locked with the machine body 100, the unlocking mechanism may be used to unlock both the carbon ribbon supply end and the carbon ribbon recovery end, and the locking between the machine body 100 and the housing 20. The connection lock or limit between the housing 20 and the body 100 may be achieved by a structure such as a snap.
In the present example shown in fig. 5 to 8, the carbon ribbon supply end includes a hollow carbon ribbon shaft 221 and a carbon ribbon paper shaft 225 sleeved on the carbon ribbon shaft 221, the two shafts are in interference fit, and a carbon ribbon coil 226 is arranged outside the carbon ribbon paper shaft 225; the carbon tape recovery end comprises a hollow carbon tape shaft 221 and a carbon tape paper shaft 225 sleeved on the carbon tape shaft 221, and the hollow carbon tape shaft 221 and the carbon tape paper shaft are in interference fit; the shell 20 is provided with an axial limiting structure for axially limiting the carbon ribbon shaft 221 (or the carbon ribbon supply end and the carbon ribbon recovery end), and the carbon ribbon supply end and the carbon ribbon recovery end have floating gaps in the axial direction of the shell 20, the first locking structure is a circumferential limiting structure for limiting the circumferential rotation of the carbon ribbon shaft 221, and when the carbon ribbon cartridge 200 is connected with the machine body 100, the disengagement executing mechanism releases the constraint of the circumferential limiting structure on the circumferential movement of the carbon ribbon shaft 221, so that the carbon ribbon supply end and the carbon ribbon recovery end can rotate along the axes thereof along with the corresponding support shafts, thereby working during printing.
The window 21 corresponding to the carbon tape shaft 221 is formed on one side of the shell 20 close to the machine body 100, the mandrel 251 is arranged on the inner wall of one side of the shell 20 far away from the machine body 100, one end of the mandrel 251 is connected with the inner wall of the shell 20, the other end of the mandrel is suspended, a limiting part 252 is arranged on the periphery of the mandrel 251 on the inner wall of the shell 20, a baffle 222 is arranged at the proximal end of the carbon tape shaft 221, the distal end of the carbon tape shaft 221 or the carbon tape paper shaft 225 is sleeved on the mandrel 251, the edges of the limiting part 252 and the window 21 are respectively blocked outside the distal end of the carbon tape paper and the baffle 222, the carbon tape shaft 221 is axially limited, gaps are reserved between the two ends of the carbon tape supply end and the carbon tape recovery end in the axial direction of the shell 20, and interference with the shell 20 can be avoided when the shell 20 is dropped and when the shell 20 is rotated in printing.
In this example, the end of the carbon ribbon shaft 221 near the window 21 is provided with a fluted disc 223 with external teeth, the first locking structure includes a clip 241 and an elastic element 242 which are disposed on the housing 20, the elastic element 242 is a spring wire or an elastic sheet, the clip 241 and the elastic element 242 are both located at the periphery of the fluted disc 223, the elastic element 242 applies an elastic force to the clip 241, so that the clip 241 stretches into and is kept in the tooth slot of the fluted disc 223, and the circumferential movement of the carbon ribbon shaft 221 is limited, thereby limiting the rotation of the carbon ribbon supply end and the carbon ribbon recovery end. In this example, the clips 241 are cantilever structures arranged on the housing 20, and the number of the clips 241 is two, corresponding to the fluted discs 223 of the two carbon ribbon shafts 221 respectively; the resilient member 242 snaps the free end of the catch 241 into the slot. The toothed disc 223 has a gap between it and the window 21 in the radial direction, avoiding interference when it is separated from the housing 20.
