Abstract
The utility model relates to the technical field of printing equipment, in particular to a printer capable of adapting to medium thickness. In order to achieve the purpose of adapting to medium thickness, the utility model adopts the technical scheme that the printer comprises a printer body, wherein a carriage unit of a printing head, a carriage unit guide shaft, as well as a slide guiding rail used for guiding the sliding of the carriage unit are mounted on the printer body; the carriage unit can rotate by going around the carriage unit guide shaft so as to adjust the clearance between the print head and a printing rubber roll; a paper guide plate which is in contact with a paper surface directly is arranged at the lower end of the carriage unit; and the upper side of the carriage unit is in slide contact with the slide guiding rail through an elastic sliding bearing system. The elastic sliding bearing system comprises a first sliding bearing and a second sliding bearing which are arranged on the two sides of the front lateral plate of the slide guiding rail, as well as a compression spring. The printer has a high degree of automation, simple and convenient operation, simple structure and good using effect.
Description
Technical field
The utility model relates to the printing device of PRN device technical field, particularly a kind of self-adapting medium thickness.
Background technology
Impact printer is widely used in prints single-sheet stationery, continuous paper, single-part stationery, multilayer carbon paper, envelope, postcard, certificate, bill and bankbook etc.But different print media has different thickness, even also has different thickness with a kind of media, such as bankbook, and certificate, along with the variation of the page, thickness also can have greatly changed.Traditional printer relies on eccentric structure, and manual adjustments realizes the variation in printhead gap, adapting to the paper of different-thickness, but can't adjust the variation in printhead gap according to the thick variation of paper automatically.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of printing device of self-adapting medium thickness is provided, and this printing device is the automaticity height not only, and is easy and simple to handle, and simple in structure, and result of use is good.
For achieving the above object, the technical solution of the utility model is: a kind of printing device of self-adapting medium thickness, comprise the printer body, described printer body is provided with word car, word car guide shaft and the rail plate in order to the slip of word car is led that printhead is installed, described word car can be around the rotation of word car guide shaft to adjust printhead and the gap of printing rubber roll, described word car lower end is provided with the lateral paper guide that directly contacts with paper, and described word car upside is through elastic sliding bearing system and described rail plate sliding-contact.
Described elastic sliding bearing system comprises first sliding bearing and second sliding bearing and a compression spring that is divided into both sides, rail plate front side board front and back, described compression spring one end is connected with first sliding bearing, the other end is connected with the carriage or the ribbon cartridge support of word car upside, the leading flank sliding-contact of described first sliding bearing and rail plate front side board, to transmit the elastic force of compression spring, the trailing flank sliding-contact of described second sliding bearing and rail plate front side board is with the gap of restriction and adjustment printer.
The utility model characteristics are to adjust printhead and the gap of printing rubber roll automatically according to the thickness of print media, and make word car and rail plate remain sliding-contact with operate as normal, have very strong practical value and wide application prospect.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Description of drawings
Fig. 1 is the organigram of the utility model embodiment;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the front view of Fig. 1;
Fig. 4 is the vertical view of Fig. 1.
Fig. 5 is the overall pattern of the utility model embodiment.
The specific embodiment
The printing device of self-adapting medium thickness of the present utility model, comprise the printer body, described printer body 15 is provided with the word car 14 that printhead 6 is installed, word car guide shaft 10 and rail plate 1 in order to the slip of word car 14 is led, described word car 14 can be around 10 rotations of word car guide shaft to adjust printhead 6 and the gap of printing rubber roll 12, described word car 14 lower ends are provided with the lateral paper guide 9 that directly contacts with paper, realize the rotation of word car with the upwards thrust that relies on paper, driving printhead 6 moves up, thereby change the gap between printhead 6 and the printing rubber roll 12, described word car 14 upsides are through elastic sliding bearing system and 1 sliding-contact of described rail plate.
In preferred embodiment of the present utility model, above-mentioned elastic sliding bearing system comprises the elastic sliding bearing and second sliding bearing 4 that is divided into both sides, rail plate front side board 16 front and back, the leading flank sliding-contact of described elastic sliding bearing and rail plate front side board 16, the trailing flank sliding-contact of described second sliding bearing 4 and rail plate front side board 16 is with the minimum clearance of restriction and adjustment printer.
In preferred embodiment of the present utility model, above-mentioned elastic sliding bearing further is made of first sliding bearing 3 and compression spring 2, described compression spring 2 one ends are connected with first sliding bearing 3, the other end is connected with the ribbon cartridge support 5 of word car upside, the leading flank sliding-contact of described first sliding bearing 3 and rail plate front side board 16 is to transmit the elastic force of compression spring 2.Above-mentioned first sliding bearing 3 and second sliding bearing 4 are divided on the carriage 7 of described word car upside.
Because be provided with compression spring 2 between first sliding bearing 3 and ribbon cartridge support 5, under the state of no paper or thin paper, the trailing flank of rail plate front side board 16 contacts with second sliding bearing 4, guarantee the minimum clearance between printhead 6 and the printing rubber roll 12; Paper is thick in behind this gap, and the trailing flank and second sliding bearing 4 separate, and the stressed increase of the leading flank of rail plate front side board 16 passes to the word car with the elastic force that compresses spring 2.In the work, first sliding bearing 3 slides on rail plate 1 surface, and compression spring 2 produces distortion, and the elastic force that will compress spring 2 by rail plate 1 passes to word car 14, this power is used to make lateral paper guide 9 to be pressed on the paper surface, the reaction force when another effect is 6 work of opposing printhead.
More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
