Technical Field

The invention belongs to the field of printers, and particularly relates to a weight type direct-reading printer for paper allowance.

Background

The printer is used as a common office supply at present, the use frequency of the printer is quite frequent, the number of consumed paper is quite large, and in order to respond to the call of state paperless office work, the printer can also play a role in saving resources and protecting the environment by performing double-sided printing on part of paper with a single printed side.

However, in the actual work, some files must use single-sided printing, some files can use double-sided printing, people often count some required specific paper quantity of oneself when using the secondary to print the paper, count a few after, when other people used once more, need count a few again, so troublesome process for in the high rhythm's office environment, in addition, because the paper after the single-sided printing often is waste paper, there is the condition that the fold was kneaded mostly, for count a few quantity further increased the degree of difficulty, to sum up the condition, make the rate of utilization of paper two-sided printing very low.

Disclosure of Invention

In order to solve the problems, the direct-reading printer with the weight type paper allowance is manufactured, and the direct-reading printer is convenient for counting the quantity of waste paper.

In order to achieve the above purpose, the invention is solved by the following technical scheme: the utility model provides a weight formula paper surplus direct-reading printer, includes the printer, and the printer includes printer body and weight charge level indicator, and the weight charge level indicator sets up on printer body, and the weight charge level indicator includes weight drive arrangement and survey hammer, and weight drive arrangement fixed mounting is on the printer, and the survey hammer hangs in weight drive arrangement below through the stay cord, and the below of survey hammer is the paper box of printer body.

Furthermore, the heavy hammer driving device comprises a motor, a rope winding wheel and a heavy hammer circuit board, the motor drives the rope winding wheel to rotate, one end of the traction rope is fixed on the rope winding wheel, the motor rotates to generate a motor rotation value, and the heavy hammer circuit board applies a conversion formula to obtain a paper residue value according to the motor rotation value.

Furthermore, the weight level meter is arranged in the printer shell, and the weight circuit board is connected with the printer processor.

Furthermore, the weight charge level indicator is detachably connected with the outside of the printer shell, and a display screen for displaying the residual paper value is arranged on the weight charge level indicator shell.

Further, the conversion formula is:

setting the position of the measuring hammer reaching the bottom of the paper box as an initial value H0;

setting the total height of the paper in a flat state as Hp;

setting the thickness of a single sheet in a flat state of the paper to be P0;

the paper residue value Cm = (Hp-H0)/P0, when Cm is an integer, the paper residue value is obtained, and when Cm contains a residue, the paper residue value is obtained after rounding.

Furthermore, a waste paper detection device is arranged below the heavy hammer level gauge.

Further, waste paper monitoring devices includes color sensor and fixed plate, and the fixed plate is put in the paper box top of flat, and a plurality of color sensor are fixed on the fixed plate.

Furthermore, a monitoring circuit board is arranged on the fixing plate, and the circuit board transmits the detection signal to the printer processor.

Furthermore, a through hole for the measuring hammer to pass through is further formed in the fixing plate.

Furthermore, the measuring hammer is a steel ball of 0.3kg-0.5 kg.

The invention has the advantages that:

(1) through setting up the weight charge level indicator on the printer, the weight charge level indicator reachs paper quantity according to the high paper conversion, adopts the measured benefit of weight charge level indicator to lie in, to having the fold or by the unevenness paper of kneading, relies on the weight of survey hammer itself, can play the effect of the paper that flattens for measured data is enough accurate.

(2) Still be equipped with waste paper detection device in the top of paper box, be provided with a plurality of color sensor on the waste paper detection device, detection range can cover more than 95% of A4 paper, can avoid the positive and negative orientation of paper to misplace.
