Description

The broadening computer printer

Technical field

The utility model relates to a kind of computer printer, particularly a kind of computer printer that can increase print span arbitrarily.

Technical background

At present, the paper feed mode of common computer printer is as follows: printing paper is front loaded from printer, makes progress below marking roll by the friction pressure roller, is pushed down by pressure roller through behind the printhead.The dolly of printhead moves horizontally, printhead is the array of dot matrix, syringe needle as impact printer impacts colour band, color dot is imprinted on the printing paper, ink-jet printer sprays tiny ink dot on printing paper, finish like this after delegation's pattern, print dolly and get back to original position, unit of marking roll clockwise direction rotation moves a unit backward with printing paper, the printing of beginning second row, go round and begin again like this, one width of cloth width of cloth pattern or literal are printed on the paper, and last printing paper is finished the printing of a piece of paper from the lower end output of printer.Move horizontally owing to print dolly, its track is across on printing paper, and it is open that printer has only upper and lower, and printing paper moves both vertically, and the amplitude of printing or Breadth Maximum are very restricted.After printer was produced, its printing amplitude or title Breadth Maximum had just been decided to get off, and can not increase print span again, and this gives engineering drawing, and advertisement design, teaching show that the work of wide cut printings such as plate brings great inconvenience.If the wideer pattern of seal just have to adopt bigger printer, and the cost of wide cut printer is higher, price is also very expensive, and the volume of printer is also very roomy, and it is also very big to take up room.

Summary of the invention

The purpose of this utility model is to provide a kind of broadening computer printer of printable any width.The purpose of this utility model is achieved through the following technical solutions: it comprises the housing of printer, inner support, paper-finding frame 1, the paper feed passage, the marking roll 13 that joins with chart drive motor 14, the printhead 3 that joins with word vehicle motor 4, the upper pressure paper wheel 12 that joins with the electric control gear 2 of upper pressure paper wheel, the following pressure roller 5 that joins with the electric control gear 6 of following pressure roller, it is characterized in that: the side at marking roll 13 is equipped with horizontal pressure roller 8 that joins with horizontal pressure roller electric control gear 7 and the horizontal paper bowl 9 that joins with horizontal paper bowl motor 16 in the both sides of paper feed passage, the both sides of paper feed passage are not sealed.Can also be provided with the chart drum 10 of a circle in the paper feed channel end, and be provided with the paper support that matches with the paper feed passage in the one or both sides of paper feed passage.Hence one can see that, and the utility model is by making paper feed passage both sides open, and increase horizontal form feeding device, thereby can realize printing the purpose of the paper of any width.

The specific embodiment

By Fig. 1 to Fig. 3 as can be known, the utility model is for ease of fed printing sheet 11, and the end of paper feed passage is provided with the chart drum 10 of a circle, so that printed paper roll is gone in the chart drum 10.About each parts of printer are installed on two the base plate 15.The course of work of the present utility model is: at first, utilize the figure that software will be to be printed to be separated into two parts (partner's part) according to the horizontal printable width of printer, we are defined as first width of cloth with it, second width of cloth figure, paper-advance unit makes printing paper 11 send into from paper-finding frame 1, chart drive motor 14 drives the rotation of marking roll 13 clockwise directions, printing paper 11 is imported marking roll 13 and printhead 3 and pressure roller 12, between 5, printhead 3 beginnings printing curve on paper, the printing paper of having printed 11 is through horizontal pressure roller 8 and horizontal paper rod 9, at this moment laterally pressure roller 8 is opened, and printing paper can pass through smoothly.Because printing paper is long, printing paper is involved in the chart drum at leisure.When first width of cloth figure print intact after, at this moment electromagnet 6 actions of the electromagnet 2 of upper pressure paper wheel and following pressure roller, upper pressure paper wheel 12 and following pressure roller 5 are unclamped, electromagnet 7 also moves simultaneously, horizontal pressure roller 8 is compressed, and laterally the horizontal paper bowl 9 of paper bowl motor 16 drivings drags to paper and the facing of width of having printed meets the place.Subsequently, the electromagnet 2 of upper pressure paper wheel and 6 actions of the electromagnet of following pressure roller, upper pressure paper wheel 12 and following pressure roller 5 are compressed, electromagnet 7 actions, horizontal pressure roller 8 is unclamped, and chart drive motor 14 drives marking roll 13 rotation counterclockwise, and printhead begins the printing of second width of cloth figure, certainly, the direction of second width of cloth figure is opposite with first width of cloth figure.Like this, two width of cloth figure have been combined into a width of cloth pattern, make the amplitude of printing increase by one times.If, printed second width of cloth figure after, have the image of having printed or not, we claim the 3rd width of cloth figure, at this moment, marking roll 13 enters the starting position of second width of cloth figure with printing paper, the action of duplicate printing second width of cloth figure again begins to print the 3rd width of cloth figure ...So, go round and begin again, then the printable any width of the utility model.

Theoretically, can repetitive operation many times, the width of printing can be wide as far as possible, but owing to make and installation errors, marking roll 13 can have error with the perpendicularity of horizontal paper bowl 9, the circularity of marking roll.Like this, can make the combination of two width of cloth figure produce deviation, number of times is many more, and deviation is big more.In general, twice or thrice print, naked eyes are not see that deviation is next.Because printing paper is bigger, smooth and easy for paper feed, at the paper support that the activity that matches with the paper feed passage is loaded onto in the right side or the both sides of printer, 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, and various detections and protected location are installed.Because this printer has horizontal paper feed, its paper feed passage must be smooth and easy, make with the higher material of fineness.Simultaneously can not have object to stop between the feed slot, the line of plate between up and down all should pass through from the chart drum back.

Drive motors generally adopts the pulse step motor, adds the adjusting that cogs, and can make the precision of action 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 is engineering drawing, copy paper, common paper and other paper that can curl.This printer is the same with common computer printer to need the drive circuit of being correlated with and the support of software, promptly is equipped with relevant driver.
