Description

A kind of thermal printer

Technical field

The utility model relates to a kind of printer, is a kind of thermal printer specifically.

Background technology

In the prior art, the critical piece of thermal printer is a thermal printing head, the operation principle of thermal printer is to use heat-sensitive paper on the one hand, thermal printing head heating in the print procedure, heat is transmitted on the heat-sensitive paper, because be heated display text and the pattern of heat-sensitive paper come out, is applicable to that postal service, fax, retail business etc. promptly beat the i.e. field of usefulness, but because literal and pattern on the heat-sensitive paper are faded by the influence of environment and time easily, the holding time is short has limited its application; Be to use colour band on the other hand, thermal printing head heating and heat passed on the colour band in the print procedure, the thermal transfer ink layer of colour band backing layer is heated and is transferred on the print media, can be on print media printing character and pattern, because the thermal transfer ink layer rub resistance on the print media, corrosion-resistant, heat-resisting, cold-resistant, make that the holding time of these literal and pattern is relative longer, use more extensive, such as bar code printing, train ticket is printed, luggage check etc., and, owing to used the colour band medium, print media can use plain paper, adhesive sticker series, thin polymer film or the like.Widely used bar code printer mainly adopts colour band to print.At present colour band mainly adopts polyester film as tape base, and tape base applies thermal transfer ink layer and back coating on large-scale coating machine, cuts and packs after having applied thermal transfer ink layer and back coating, and packaging product just can use on thermal printer.This process more complicated, operation is more, and man power and material's loss is big, colour band has only a spot of thermal transfer ink layer to be transferred on the print media during printing, makes that the thermal transfer ink layer utilization rate on the colour band is not high, has waste of material, and the degradability of polyester film is relatively poor, forms environmental pollution.

The utility model content

Goal of the invention: in order to overcome the deficiencies in the prior art, the purpose of this utility model be can save cost, environmental protection, simple in structure, easy operating in order to provide a kind of, tape base can reusable thermal printer.

Technical scheme: for realizing above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of thermal printer, thermal printing mechanism are provided with the tape base device that can repeat to apply.

Described thermal printing mechanism comprises thermal printing head and prints rubber roll; The described tape base device that repeats to apply comprises reusable tape base, puts the tape base device, applying device, take-up based devices; One end of described reusable tape base is connected to be put on the tape base device, is connected on the take-up based devices after between the coated device of the other end, thermal printing head and the printing rubber roll.

Operation principle of the present utility model: the tape base of certain-length is placed on the tape base device, one end connects puts the tape base device, be connected on the take-up based devices after between the coated device of the other end, thermal printing head and the printing rubber roll, during work, tape base moves to the take-up based devices from putting the tape base device under the pulling function of take-up based devices, simultaneously, during the coated device of tape base, application roll is coated to thermal transfer ink layer on the tape base, thermal printing head is pressed in to be printed on the rubber roll, and the thermal transfer ink layer on the tape base is transferred on the print media under the printhead effect.After putting tape base on the tape base device and using, stop coating and print job, and will put tape base device backward rotation, tape base on the take-up based devices is moved to putting tape base device direction by the take-up based devices, can print operation once more after tape base moves and finishes, so just can realize reusing tape base.
