Description

Inking mechanism of color ribbon

Technical Field

The utility model particularly relates to an inking mechanism of a color ribbon.

Background

Color bands are a type of printing consumable that we are familiar with. From the earliest mechanical impact type English printers to the later computer needle type printers, color bars were used. The ribbon is made by using nylon yarn as raw material to weave ribbon base and making it undergo the process of ink colouring treatment. The ink ribbon works on the principle that dot matrix firing pins in the head of a needle printer or letter striking pieces in an English typewriter are utilized to strike the printing ink ribbon, so that a printing effect is generated on printing paper. In order to add the printing ink on the ribbon, the inking mechanism used in the existing production comprises a mounting frame, an operating platform is arranged on the mounting frame, inking rollers are arranged on the mounting frame, guide structures are fixedly arranged on two sides of the operating platform respectively, the ribbon is pulled by a tractor and then conveyed and attached to the outer surface of the inking roller through the guide structures, and the ink on the inking roller is used for inking the ribbon. However, when the guide structure has an assembly error, the ink ribbon is guided to a reduced contact area with the inking cylinder by the guide structure, and the inking quality is affected.

The utility model provides an inking mechanism of typewriter ribbon, refers to fig. 1-2, including mount 1, be provided with operation panel 2 on mount 1, be provided with on the mount 1 and be used for inking the typewriter ribbon 30 cylinder 3 that inking, inking cylinder 3's one side intercommunication has ink horn 4, is provided with guide structure 5 respectively in the both sides of mount 1, and every guide structure 5 is the slip setting with mount 1, be provided with a plurality of locking position 6 on the mount 1, the last retaining member 7 that matches of locking position 6, two guide structure 5 can remove respectively for mount 1 to typewriter ribbon 30 all laminate on guide structure 5 and inking cylinder 3's surface, and typewriter ribbon 30 is in same horizontal line from left to right, and rethread retaining member 7 passes guide structure 5 and inserts locking position 6 so that guide structure 5 is fixed on mount 1.

Further, a guide groove 10 is formed in the fixing frame 1, a limiting block 8 is arranged on the guide structure 5, and the guide structure 5 can drive the limiting block 8 to move in the guide groove 10 in the horizontal direction under the action of external force.

Further, the limiting block 8 is provided with a ball 511, and the limiting block 8 drives the ball 511 to be in rolling fit with the guide groove 10 when moving relative to the fixing frame 1.

Further, a refining roller 12 is arranged on the fixing frame 1, the refining roller 12 is positioned at one side of the inking roller 3, and the lower end surface of the refining roller 12 is attached to the color ribbon 30.

Further, the guiding structure 5 includes a mounting seat 51, the limiting block 8 is disposed on the mounting seat 51, a fixing shaft 52 is disposed on the mounting seat 51, and a guiding wheel 53 is rotatably connected to the fixing shaft 52.

The working principle of the utility model is as follows:

before the ink ribbon 30 needs to be inked, the guiding structure 5 moves relative to the fixing frame 1 under the action of external force (the external force can be realized by means of a telescopic cylinder or manual pushing mode), when the ink ribbon 30 is adjusted to be attached to the outer surfaces of the two guiding wheels 53, the ink feeding roller 3 and the refining roller 12 (as shown in fig. 1), the ink ribbon 30 is positioned on the same horizontal line from left to right, and the locking piece 7 is inserted into the locking position 6 through the mounting seat 51 so as to fix the guiding structure 5 on the fixing frame 1. The locking member 7 and the locking position 6 described above can be implemented as embodiment 1 by selecting bolts and bolt holes. At this time, the tractor is started, the ribbon 30 is pulled to move onto the operating platform 2 along the guide wheel 53 under the action of the tractor, and when the ribbon 30 continues to move, the inking cylinder 3 is driven to rotate; the ink on the ink cartridge 4 can be ejected on the outer surface of the ink-applying cylinder 3 by the ink-jet head, and the ink ribbon 30 contacts the ink on the outer surface of the ink-applying cylinder 3 during rightward movement, thereby applying ink to the ink ribbon 30. The material-homogenizing cylinder 12 is arranged on one side of the inking cylinder 3, when the inked ribbon 30 continues to move rightwards, the material-homogenizing cylinder 12 can squeeze out the redundant ink on the ribbon 30 to two sides, so that the influence of the excessive thickness of the ink on the inking effect is prevented; in order to make the inking cylinder 3 better ink the ink ribbon 30, the periphery of the inking cylinder 3 is optionally sleeved with an inking cotton sleeve 50, so that the inking cotton sleeve 50 adsorbs the ink on the ink box 4, and the ink ribbon 30 can be more conveniently inked. The position of the guide structure 5 on the fixing frame 1 is adjusted, so that the color ribbon 30 cannot generate position deviation with the inking cylinder 3 in inking, the color ribbon 30 is better attached to the outer surface of the inking cylinder 3, and inking effect is improved.

On the basis of the above technical scheme, considering that when the limiting block 8 moves in the guide groove 10, the surface friction force of the limiting block 8 and the guide groove 10 can enable the limiting block 8 to be blocked or generate noise in the moving process, the ball 511 is arranged on the limiting block 8, and the smoothness of the movement of the guide structure 5 relative to the fixing frame 1 can be improved through the cooperation of the ball 511 and the guide groove 10.

While the present utility model has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications can be made therein without departing from the spirit and scope of the utility model as defined in the following claims.
