Abstract

A printing medium discharging and feeding mechanism of thermal-sensitive printer which mainly resolves the problem that the thermal-sensitive scroll printers can only carry out single color printing comprises a frame, a thermal-sensitive printing head, a printing rubber-covered roll and discharging and feeding mechanisms which are arranged on the frame and mutually parallel to each other, whereinthe discharging and feeding mechanisms which are arranged in pairs comprise discharging shafts and feeding shafts. The printing medium discharging and feeding mechanism of thermal-sensitive printer ischaracterized in that a pair or a multiple pairs of the discharging and feeding mechanisms can be arranged. Because the discharging and feeding mechanisms can be arranged in multiple pairs, each paircan support consumables with one color or multiple colors, each color band and cloth are synchronous charged and printed between the thermal-sensitive printing head and the printing rubber-covered roll, thereby realizing two-color or multi-color printing and satisfying the making needs of colorful scrolls.

Description

The print media material retractable mechanism of thermal printer

Technical field

The utility model relates to a kind of thermal printer, specifically a kind of print media material retractable mechanism of thermal printer.

Background technology

At present, thermal printer especially in the vertically hung scroll thermal printer, can only print at a kind of color, is provided with a pair of dispensing shaft and collecting shaft at the print media of this a kind of color.In actual applications, users require to print double-colored and the polychrome vertically hung scroll, but present vertically hung scroll thermal printer obviously can not reach this requirement.

The utility model content

The purpose of this utility model is to overcome the supporting construction that the deficiencies in the prior art provide a kind of print media of thermal printer, and this mechanism can realize monochrome or polychrome thermal printing.

Technical solution adopted in the utility model is: the material retractable mechanism of this thermal printer, comprise frame, be arranged on material retractable mechanism parallel to each other on the frame, material retractable mechanism is provided with in pairs, comprises collecting shaft and dispensing shaft, it is characterized in that material retractable mechanism can be made as one or more pairs of.

How right described material retractable mechanism be, each supports the consumptive material of one or more colors respectively to collecting shaft and dispensing shaft, and the consumptive material of every kind of color is staggered in its corresponding position.

The beneficial effects of the utility model are: because how right dispensing shaft and corresponding collecting shaft are, each is to supporting the consumptive material of one or more colors respectively, each colour band and cloth be charging synchronously between thermal printing head and rubber roll, print simultaneously, realized double-colored or multi-color printing, satisfied the making needs of multicolour vertically hung scroll.

Description of drawings

Fig. 1 is a two color thermal printing machine structural principle schematic diagram of the present utility model;

Fig. 2 is a two color thermal printing machine perspective view of the present utility model.

Among the figure: 1 frame, 21 first tensioning shafts, 22 second tensioning shafts, 3 rubber rolls, 4 thermal printing heads, 51 first colour band dispensing shafts, 52 first colour band collecting shafts, 61 second colour band dispensing shafts, 62 second colour band collecting shafts, 71 cloth dispensing shafts, 72 cloth collecting shafts.

The specific embodiment

Be illustrated in figure 1 as the print media material retractable mechanism of two color thermal printing machine, it comprises frame 1, colour band dispensing shaft and colour band collecting shaft, cloth dispensing shaft 71 and cloth collecting shaft 72, axle head at colour band dispensing shaft, colour band collecting shaft, cloth dispensing shaft and cloth collecting shaft respectively is connected an independently motor, under motor effect separately, each colour band and cloth be charging synchronously between thermal printing head and rubber roll, has realized double-colored printing.

Respectively one of cloth dispensing shaft 71 and corresponding cloth collecting shaft 72.

Colour band dispensing shaft and corresponding colour band collecting shaft are two pairs, the i.e. first colour band dispensing shaft 51 and the first colour band collecting shaft 52, the second colour band dispensing shaft 61 and the second colour band collecting shaft 62, each is to supporting the colour band of one or more colors respectively, and the position of the colour band of different colours on its corresponding colour band dispensing shaft and colour band collecting shaft is staggered.

Feed side at rubber roll 3 and thermal printing head 4 also is provided with first tensioning shaft 21, and this first tensioning shaft 21 is positioned at the top of colour band and cloth, plays vertical tensioning and laterally flattening effect, has improved print quality.Exit side at rubber roll 3 and thermal printing head 4 also is provided with second tensioning shaft 22, and this second tensioning shaft 22 is positioned at the top of cloth, cloth is played vertical tensioning and laterally flattens booster action, so that prepare for the cloth heat sublimation.

Its installment state is, cloth is nested with on cloth dispensing shaft 71 by feedstock direction, the colour band of two kinds of different colors is nested with respectively on the first colour band dispensing shaft 51 and the second colour band dispensing shaft 61, and mutually noninterfere is staggered in the position of the colour band of two kinds of different colors above cloth.Cloth and two kinds of colour bands enter between rubber roll 3 and the thermal printing head 4 after through first tensioning shaft 21, print finish after, the colour band of two kinds of different colors curls respectively on the first colour band collecting shaft 52 and the second colour band collecting shaft 62; Cloth enters in the heat sublimation device through second tensioning shaft 22, curls on cloth collecting shaft 72 after heating.

The utility model is not limited to the foregoing description, by increasing the quantity of colour band dispensing shaft and colour band collecting shaft, can realize multi-color printings such as three looks, four look printings.To this, those skilled in the art implement not difficult.

Claims

1, a kind of print media material retractable mechanism of thermal printer, comprise frame, thermal printing head, printing rubber roll, be arranged on material retractable mechanism parallel to each other on the frame, material retractable mechanism is provided with in pairs, comprises collecting shaft and dispensing shaft, it is characterized in that: material retractable mechanism can be made as one or more pairs of.

2, the print media material retractable mechanism of thermal printer according to claim 1, it is characterized in that: how right described material retractable mechanism be, each supports the consumptive material of one or more colors respectively to collecting shaft and dispensing shaft, and the consumptive material of every kind of color is staggered in its corresponding position.
