The computer printer is characterized in that a transverse paper pressing wheel connected with an electric control device of the transverse paper pressing wheel and a transverse paper roller connected with a transverse paper roller motor are installed on the two sides of the paper feeding channel and located on the side of the printing roller; the two sides of the paper feeding channel are not closed; a circular paper drum is arranged on the end portion of the paper feeding channel; paper supporting frames matched with the paper feeding channel are arranged on one side or the two sides of the paper feeding channel. The computer printer is capable of completing printing tasks with any width.
Description
Technical field
The present invention relates to a kind of computer printer that can increase arbitrarily print span.
Background technology
At present, the paper feed mode of common computer printer is as follows: front loaded from printer of printing paper, by friction pressure roller below marking roll upwards, pushed down by pressure roller after printhead.The dolly of printhead moves horizontally, printhead is the array of dot matrix, meter primary drying as impact printer hits colour band, color dot is imprinted on printing paper, ink-jet printer sprays tiny ink dot on printing paper, after completing a line pattern like this, print dolly and get back to original position, marking roll rotates a unit clockwise, by a printing paper mobile unit backward, starts the printing of the second row, go round and begin again like this, be printed on paper by a width width pattern or word, last printing paper exports from the lower end of printer, completes the printing of a piece of paper.Move horizontally owing to printing dolly, its track is across on printing paper, and printer only has upper and lower to be open, and printing paper moves both vertically, and so just makes the amplitude of printing or Breadth Maximum be very restricted.After printer is produced, its printing amplitude or title Breadth Maximum have just been determined to get off, and can not increase print span again, the work that the wide cuts such as this gives engineering drawing, advertisement design, demonstration board for teaching print brings great inconvenience.If print wider pattern, just have to adopt larger printer, and the cost of wide-format printer is higher, price is also very expensive, and the volume of printer is also very roomy, takes up room also very large.
Summary of the invention
For solving above-mentioned existing shortcoming, main purpose of the present invention is the computer printer that can increase arbitrarily print span providing a kind of practicality, can complete the print out task of any width.
For reaching above-described object, a kind of computer printer that can increase arbitrarily print span of the present invention takes following technical scheme:
A kind of computer printer that can increase arbitrarily print span, comprise the housing of printer, inner support, paper-finding frame, paper-advance unit, paper feed passage, the marking roll connected with chart drive motor, the printhead connected with word vehicle motor, the upper pressure paper that the electric control gear of taking turns with upper pressure paper connects is taken turns, the lower pressure roller connected with the electric control gear of lower pressure roller, it is characterized in that, the horizontal paper bowl being provided with in the side of marking roll the horizontal pressure roller connected with horizontal pressure roller electric control gear in the both sides of paper feed passage and connecting with horizontal paper bowl motor, the both sides of paper feed passage are not closed, the chart drum of a circle is provided with in paper feed channel end, the paper support that to match with paper feed passage is provided with in the one or both sides of paper feed passage.
Adopt the present invention of as above technical scheme, there is following beneficial effect:
The present invention by making paper feed passage both sides open, and increases horizontal form feeding device, thus can realize the object of the paper printing any width.

Fig. 2 is supporting plate structure schematic diagram of the present invention.
Fig. 3 is paper support structural representation of the present invention.
detailed description of the invention
In order to further illustrate the present invention, be described further below in conjunction with accompanying drawing:
As shown in Figure 1-Figure 3, a kind of computer printer that can increase arbitrarily print span of the present invention, for ease of fed printing sheet 11, the end of paper feed passage is provided with the chart drum 10 of a circle, so that printed paper roll enters in chart drum 10.Each parts of printer are arranged on the base plate 15 of two pieces, left and right.The course of work of the present invention is: first, utilize software that figure to be printed is separated into two parts (partner part > according to the horizontal printable width of printer, we are defined as the first width, second width figure, paper-advance unit makes printing paper 11 send into from paper-finding frame 1, chart drive motor 14 drives marking roll 13 to rotate clockwise, printing paper 11 is imported marking roll 13 and printhead 3 and pressure roller 12, between 5, printhead 3 starts printing curve on paper, the printing paper 11 printed is through horizontal pressure roller 8 and horizontal paper rod 9, at this moment horizontal pressure roller 8 is opened, printing paper can pass through smoothly.Because printing paper is long, printing paper is involved in chart drum at leisure.When the first width figure print intact after, at this moment the electromagnet 2 of upper pressure paper wheel and electromagnet 6 action of lower pressure roller, upper pressure paper wheel 12 and lower pressure roller 5 are unclamped, electromagnet 7 also action simultaneously, compressed by horizontal pressure roller 8, horizontal paper bowl motor 16 drives horizontal paper bowl 9 to be dragged to by paper and the facing of width printed meets place.Subsequently, the electromagnet 2 of upper pressure paper wheel and electromagnet 6 action of lower pressure roller, upper pressure paper wheel 12 and lower pressure roller 5 are compressed, electromagnet 7 action, unclamped by horizontal pressure roller 8, chart drive motor 14 drives marking roll 13 counterclockwise to rotate, and printhead starts the printing of the second width figure, certainly, the direction of the second width figure is contrary with the first width figure.Like this, two width figure have been combined into a width pattern, make the amplitude of printing add one times.If after having printed the second width figure, have the image printed or not, we have claimed the 3rd width figure, and at this moment, printing paper is entered the starting position of the second width figure by marking roll 13, again the action of duplicate printing second width figure, start to print the 3rd width figure ...So, go round and begin again, then the printable any width of the present invention.
Theoretically, can repetitive operation many times, the width of printing can be as far as possible wide, but due to the error manufactured and install, marking roll 13 can have error with the perpendicularity of horizontal paper bowl 9, the circularity of marking roll.Like this, the combination of two width figure can be made to produce deviation, and number of times is more, and deviation is larger.In general, twice or thrice print, naked eyes do not see that deviation is come.Because printing paper is larger, in order to paper feed is smooth and easy, load onto the paper support of the activity matched with paper feed passage on the right side of printer or both sides, paper support can be that plastics are made, and also can make by other material.Base plate can be cast aluminium or aluminium alloy casting die or other material.This printer also can be the same with common computer printer, installs various detection and protected location.Because this printer has horizontal paper feed, its paper feed passage must be smooth and easy, and the material higher by fineness is made.Object can not be had to stop between feed slot, the line between plate is upper and lower all should pass behind from chart drum simultaneously.
Drive motors generally adopts pulse step motor, adds the adjustment that cogs, and the precision of action can be made very high, is convenient to control.The printhead of this printer can be click type stylus printer or multi-color ink jet printhead.This printer print media applicatory be engineering drawing, copy paper, common paper and other can be curling paper.The support that need drive circuit and the software of being correlated with the same as common computer printer of this printer, is namely equipped with relevant driver.
