Abstract
The invention belongs to a needle printer printing head capable of continuously printing. The needle printer printing head comprises a convex part assembly (3), a guide body (17), a retainer compression ring (6), a circuit board (24), a magnetic yoke assembly (20), a clapper (18), an iron pressure plate (12) and a pressure plate spring (21), and is characterized in that an aluminum housing (4) for heat dissipation is arranged on the exterior of the magnetic yoke assembly (20); a fan base (9) is mounted on the iron pressure plate (12); a fan (9-1) is mounted on the fan base (9), or is replaced with cooling fins. The heat generated by the printing head during working is dissipated through the aluminum housing, the fan base, the fan or the cooling fins, so that the printing head does not have a rise in temperature and can continuously perform printing for a long time, shut-down for cooling is avoided, the service life of the printing head is greatly prolonged.
Description
Technical field
The invention belongs to a kind of parts of printer, particularly a kind of needle type printer printing head that can print continuously.
Background technology
Can the parts of printer be a lot, and wherein printer port of printer is one of printer most critical parts, service life of printer and continual continuous printing be the important indicator weighing printer quality.160 needle type print heads that existing people use, printhead prints easy heating for a long time, particularly in high temperature environments; easy shutdown, after temperature reduces, then row prints; can print speed be affected like this, damage printhead can be caused if do not shut down, affecting service life.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, provide one can continuous operation and can quick heat radiating, the needle type printer printing head that can print continuously of long service life.
The technical scheme that technical solution problem of the present invention adopts is: a kind of needle type printer printing head that can print continuously, comprise boss assembly, guide way, retainer pressure ring, circuit board, yoke assembly, clappers, iron pressing plate and rag iron spring, it is characterized in that the aluminum hull of heat transmission is equipped with in yoke assembly outside, above iron pressing plate, fan base is housed, fan base is equipped with fan, or changes fan into fin.
The invention has the beneficial effects as follows: the heat produced during the work of this invention printhead, come out by aluminum hull, fan base, fan or fin, printhead can not generate heat, and can long-time continuous print, need not shut down cooling, service life extends greatly.
Accompanying drawing explanation
Illustrate with embodiment below in conjunction with accompanying drawing.
Fig. 1 is the sectional front view of the needle type printer printing head that can print continuously.
In figure: 1-pin guide card; The secondary guide card A of 2-; 3-boss assembly; 4-aluminum hull; The secondary guide card B of 5-; 6-retainer pressure ring; 7-has the final say compressing tablet; 8-locating snap ring; 9-fan base; 9-1-fan; 10-stop rubber ring; 11-partition; 12-iron pressing plate; The secondary guide card C of 13-; 14-copper packing; 15-pressure ring; 16-felt; 17-guide way; 18-has the final say; 19-print needle; 20-yoke assembly; 21-rag iron spring; 22-skeleton; 23-compression spring; 24-circuit board.
Detailed description of the invention
Embodiment, with reference to accompanying drawing, a kind of needle type printer printing head that can print continuously, comprise boss assembly 3, guide way 17, retainer pressure ring 6, circuit board 24, yoke assembly 20, clappers 18, iron pressing plate 12 and rag iron spring 21, it is characterized in that the aluminum hull 4 of heat transmission is equipped with in yoke assembly 20 outside, iron pressing plate 12 is equipped with fan base 9 above, fan base 9 is equipped with fan 9-1, or changes fan 9-1 into fin.Yoke assembly 20 is contained in aluminum hull 4; The center lower end of boss assembly 3 is equipped with pin guide card 1, and secondary guide card A2 is equipped with at middle part, and secondary guide card B5 is equipped with on top; Secondary guide card B5, built with compression spring 23 and print needle 19, is equipped with secondary guide card C13 above; The upper end of boss assembly 3 is built with aluminum hull 4, and aluminum hull 4 is built with yoke assembly 20, and yoke assembly 20 is built with skeleton 22; Guide way 17 yoke assembly 20 is equipped with, guide way 17 is built with clappers 18, clappers 18 are equipped with retainer pressure ring 6 above, groove above retainer pressure ring 6 is built with felt 16, and retainer pressure ring 6 is equipped with clappers compressing tablet 7 above, and the centre bore of clappers compressing tablet 7 is built with locating snap ring 8, the in-built copper packing 14 of central recess of locating snap ring 8, copper packing 14 is equipped with stop rubber ring 10 above, and partition 11 is housed on stop rubber ring 10, and partition 11 is equipped with pressure ring 15 above; Pressure ring 15 is equipped with iron pressing plate 12, boss assembly 3, is fixed together with rag iron spring 21 between aluminum hull 4 and iron pressing plate 12.
The course of work of this invention is: when the drive coil in yoke assembly 20 is energized, magnetic force attracts clappers 18 to move, 18 impact print needles 19 of simultaneously having the final say clash into along the pin hole on secondary guide card C13, secondary guide card B5, secondary guide card A2 and pin guide card 1 to colour band, ink on colour band is clashed into by print needle 19 and penetrates on printing paper, stays next round dot.When after the current vanishes in drive coil, the elastic reset of the compression spring 23 that print needle 19 is reset goes back to home position, completes and once prints action.Print needle 19 utilizes the software of establishment in advance automatically to control, and completes print job.
