Description

Impact printer

Technical field

Bill printing field is the utility model is related to, more particularly, to a kind of impact printer.

Background technology

At present, there is miscellaneous impact printer on the market, species is various；Wherein there is the cover of an impact printer Opened split typely towards the right and left, and cutting knife is arranged on the centre of cover and uncapped place, the position of printhead cutting knife corresponding with carbon ribbon Put be arranged on cover covering support on, the pin type motor of this kind of structure, can Fast Installation printing paper in paper storehouses, installation side Just；But cutting knife is arranged on cover, the regular needs of cover are repeatedly opened and closed, and the cover at both ends is hinged on casing, Therefore the cutting knife on the cover is in cover closure state, easily occur built on the sand, the phenomenon of displacement, cause operator to enter During row paper-tear picture, it is difficult to impetus is found, so as to which printing paper is difficult to tear.

The content of the invention

Main purpose of the present utility model be to provide it is a kind of can quick paper-tear picture impact printer.

To realize above-mentioned main purpose, impact printer provided by the utility model, including casing and cover, cover hinge Pick shell；

Free end in casing close to casing is provided with movement, and paper storehouses, paper are provided between movement and the hinged end of casing Roll shaft is installed, roller bearing crosses paper storehouses in the side wall in storehouse；Movement includes support, and close paper storehouses are provided with guide plate on support, lead It is obliquely installed to plate towards support, the first paper feed passage is formed between guide plate and support, paper advance mechanism is provided with paper feed passage； Fixture is provided with support, fixture includes vertical plate, the raised plate vertical with vertical plate, guide rail is provided with vertical plate, The bearing of trend of guide rail is consistent with the direction of principal axis of roll shaft, and the word car that can be slided along the direction of principal axis of guide rail is provided with guide rail, described Word car connects printhead, is arranged with carbon tape box on fixture, and printhead is towards the carbon ribbon of carbon tape box and adjacent with the carbon ribbon of carbon tape box Connect；Gap between the carbon ribbon and guide plate of carbon tape box is the exit slot of paper feed passage；

Paper cutting mechanism is additionally provided with support, paper cutting mechanism is hinged support；Paper cutting mechanism includes the first cut paper block and second Cut paper block, the first cut paper block are provided with the first hand papercutter close to the side of the second cut paper block, and the second cut paper block is close to the first cut paper The side of block is provided with the second hand papercutter, and the gap between the first hand papercutter and the second hand papercutter is the paper delivery of the second paper feed passage Mouthful；Paper cutting mechanism also includes the connecting plate of be hinged support both sides, and the first end of connecting plate is fixed with the second cut paper block, the first cut paper Block is movably disposed on the second end of connecting plate.

From such scheme, impact printer of the present utility model is simple in construction, and cutter mechanism is hinged on support, Directly paper cutting mechanism can be opened when printing paper is set, it is easy to operate；The paper cutting mechanism of one has two hand papercutters, wherein the Two hand papercutters are in stationary state, therefore the paper cutting mechanism of one ensures the steadiness of hand papercutter in print procedure, avoids out The problem of now caused paper-tear picture is not quick built on the sand due to hand papercutter, transportable first cut paper block can be according to actual use feelings Condition is adjusted, and improves the using flexible degree of paper cutting mechanism.

Further scheme is that paper advance mechanism includes two series cylinders, and two series cylinders are collinearly set, and a series cylinder, which is arranged on, leads To on plate, another series cylinder is arranged on support.

As can be seen here, printing paper moves along paper feed passage, i.e. intermittent motion of the printing paper between two series cylinders, two In the presence of series cylinder, quickly printing paper can be arranged in paper feed passage, and printing paper motion is driven in print procedure.

Further scheme is that the bottom of the second cut paper block is provided with limiting plate towards guide plate.

As can be seen here, the limiting plate in the second cut paper block bottom is carried out spacing to paper cutting mechanism, avoids paper cutting mechanism from shifting, The exit slot of the gap between two cut paper blocks and paper feed passage is caused to produce the situation of dislocation.

Further scheme is that the carbon ribbon of carbon tape box is set between support and raised plate.

As can be seen here, carbon ribbon is arranged using the distance between raised plate and support, effectively carries out carbon ribbon spacing, avoid carbon It is excessive that band moves up and down scope in print procedure.

Further scheme is that the both sides of support are provided with locking piece, and carbon tape box is arranged between locking piece.

It can be seen that the box body of carbon tape box can be fixed on support by locking piece, carbon tape box is avoided to be vibrated in print procedure, from And cause carbon ribbon unstable, the situation of printing effect difference.
