Description

Printer for office

Technical Field

The invention belongs to the technical field of printers, and particularly relates to an office printer.

Background

The printer is one of the output devices of the computer, the printer prints the processing result of the computer on the relevant medium, the printer usually uses paper to print various contents, the printer has wide application places, and is used for various occasions, for example, the novel printer disclosed by CN206067193U comprises a printer shell, an ink jet device is arranged in the printer shell, a paper supply mechanism is arranged in the printer shell and positioned below the ink jet device, the paper supply mechanism comprises a paper supply box positioned at the bottom of the printer shell and a guide roller positioned above the paper supply box, a rotating roller is arranged at one side of the guide roller, two opposite paper conveying rollers are arranged at the other side of the guide roller, an electric heating pipe is arranged in each paper conveying roller, a paper receiving box is arranged below each paper conveying roller, the paper passes through the two paper conveying rollers, the electric heating pipe in each paper conveying roller heats the paper when the paper is conveyed, so that ink on the surface of the paper can be dried quickly, preventing the writing from being fuzzy. However, most of the printing is single-sided printing, in order to respond to energy conservation and emission reduction, reduce printing paper and protect forest calls, most office places can print again by using waste paper printed once, when the waste paper is used for printing, if the placed positions are not right, the original printing surface can be printed again, so that the handwriting on the paper cannot be seen clearly, if the printing amount is too large, the paper needs to be picked up independently, corresponding printing contents need to be found, and the printing is carried out again, so that the time consumption is too long and the operation is troublesome, and the enthusiasm of people for recycling the waste paper is influenced.

Based on this, the prior art needs to provide an office printer, which can determine the printing surface and blank surface, and take corresponding measures to process, thereby reducing the complexity of waste paper printing.

Disclosure of Invention

The invention provides an office printer aiming at the defects of the prior art.

The invention relates to an office printer, which comprises a printer shell, wherein a display is arranged on the printer shell, the display is connected with a processor, an ink jet mechanism is arranged in the printer shell, an upper end cover is arranged at the top of the printer shell, a paper outlet is formed in the upper end cover, a paper supply mechanism is arranged in the printer shell and positioned below the ink jet mechanism, the paper supply mechanism comprises a paper supply box positioned at the bottom of the printer shell and a guide roller positioned above the paper supply box, a rotating roller is arranged on one side of the guide roller, two opposite paper conveying rollers are arranged on the other side of the guide roller, and an electric heating pipe is arranged in each paper conveying roller; the paper feeding box is internally provided with a detection mechanism, the detection mechanism comprises a photoelectric sensor and a paper turning device, the paper turning device drives paper to turn, the photoelectric sensor is aligned with one side of the paper turning device, when the photoelectric sensor senses that writing is on the paper in the same orientation, the writing is fed back to the processor, the processor gives an alarm through a display and displays a corresponding page number, and if the writing is not sensed, the paper turning device stops working and is ready for printing.

The working principle of the invention is as follows: when the non-printed printing paper is used, the detection mechanism is not started, the paper feeding box is used for placing the paper, the guide roller is arranged above the paper feeding box, the rotating roller is arranged on one side of the guide roller, the two opposite paper conveying rollers are arranged on the other side of the guide roller, printing is started, the paper passes through the space between the two paper conveying rollers, and when the paper is conveyed, the electric heating pipe in the paper conveying rollers simultaneously heats the paper, so that ink on the surface of the paper is dried quickly, and writing blurring is prevented.

When using waste paper, detection mechanism starts, detection mechanism includes photoelectric sensing ware and paper turner, the paper turner drives the paper upset, photoelectric sensing ware aims at one side of paper upset, has the writing when photoelectric sensing ware senses on the paper of same orientation, will feed back the treater to show and report to the police through the display, the operator hears the back of reporting to the police, takes out waste paper, puts into the paper supply box once more after adjusting the position, continue the inspection, if there is not the writing, then paper turner stop work, prepare to print.

The invention has the beneficial effects that: when more waste paper exists, the orientation of blank pages of the waste paper in the middle position may be inconsistent, and therefore, the detection mechanism is arranged in the paper supply box, specifically, the paper is turned through the paper turning device, whether a handwriting face exists in the same orientation is sensed through the photoelectric sensor, if yes, the detection mechanism gives an alarm and displays to remind people to adjust the position, if not, printing is started, and compared with the situation that the direction is wrong after printing in the prior art and then processing is carried out, the complexity and time for printing the waste paper are effectively reduced.

Further, the paper turning device comprises a shifting sheet and a moving assembly for driving the shifting sheet to move horizontally and upwards, the moving assembly comprises an L-shaped sliding rail and a moving motor, a transmission chain is arranged at the end part of the L-shaped sliding rail through a chain wheel sleeve, one of the chain wheels is connected with a rotating shaft of the moving motor, and one side of the shifting sheet is fixedly connected with the chain.

In one embodiment, the poking sheet can move horizontally and upwards along with the transmission chain, and after the flipping is finished, the moving motor continues to rotate, and the poking sheet returns to the initial position.

Further, the paper turning device comprises a shifting sheet and a moving assembly for driving the shifting sheet to move up and down, the moving assembly comprises a vertical sliding rail and a moving motor, a transmission chain is arranged at the end part of the vertical sliding rail through a chain wheel sleeve, one of the chain wheels is connected with a rotating shaft of the moving motor, and one side of the shifting sheet is fixedly connected with the chain.

In the second embodiment, the shifting piece can move clockwise along with the transmission chain, and after the shifting piece is turned over, the shifting piece returns to the initial position after winding the vertical slide rail for a circle.

Furthermore, the contact surface of the plectrum and the paper is provided with a rugged anti-slip rubber layer. The friction between the paper and the uneven rubber anti-slip layer is increased, and each piece of paper can be turned over sufficiently.

Further, the rubber anti-skid layer is granular or linear.

Further, the display displays data on whether the waste paper contains a staple and a clip. When the photoelectric sensor senses that the staple and the clip exist in the waste paper, the waste paper is processed by the processor and then displayed on the display, corresponding pages are specifically displayed, people take out the waste paper, can quickly find out the corresponding position, and take down the staple and the clip.

Further, a nail removing sheet is arranged outside the printer shell. The staple is removed using a staple removing sheet.

Furthermore, the nail nipping sheet is connected with a turnover sheet, and the nail nipping sheet is hidden in the printer shell after the turnover sheet is turned over. When the nail nipping device is not used, the nail nipping piece is hidden after being turned over.
