Abstract
The utility model relates to a tension control printer. The homogeneous product is not capable of guaranteeing stable tension while printing continuous medium in the prior art, and the instability is developed during the movement of the medium. The utility model is provided with a middle roller (7) between a medium intake pressure roller (3) and a wrap-up device (5), and the middle roller (7) is out of the straight connecting line of the medium intake pressure roller (3) and the wrap-up device (5), the middle roller (7) is provided with a pressure sensing device (8), thereby achieving the purpose of that the medium is capable of moving under the stable tension, and the control on the continuous medium tension.
Description
Technical field
The utility model relates to a kind of printer, particularly a kind of printer with tension force control, it mainly is applicable to the tension force of the various ink-jet printing medias of control in print procedure on the various ink-jet printers, is particularly useful for controlling the tension force of continuous media in print procedure.
Background technology
Its structure of like product of the prior art as shown in Figure 1, this printer mainly by unwinding device 1 ', slide rail 2 ', medium transport pressure roller 3 ', shower nozzle 4 ' and wrap-up 5 ' form, shower nozzle 4 ' slide rail 2 ' on move around, print media 6 ' carry by thrust unit, shower nozzle 4 ' pressing the computer control instruction sprays ink, forms required literal or pattern.In ink-jet printer in order to guarantee printing precision in shower nozzle 4 ' direction of motion and medium 6 ' direction of motion, usually in shower nozzle 4 ' direction of motion grating (linear grating or rotating grating) is set, directly obtain the movement position grating signal during shower nozzle 4 ' motion, therefore in the control accuracy of shower nozzle 4 ' direction of motion than higher.But medium 6 ' motion by medium transport pressure roller 3 ' transmission, though medium transport pressure roller 3 ' rotation can accurately control by rotating grating, the medium 6 that is transmitted ' be can be selected different media for use according to the difference of the demand of printing.Rigidity owing to common printing paper when printing individual sheets (for example: A3, A4 paper) is bigger, and the quality of single-sheet stationery is little, therefore can also reach the purpose of accurate conveyance of sheets by test and fine adjustment, when carrying continuous media, when particularly soft plastic foil or textile, because continuous media is with the package form, is unwinding device 1 ' release, also be with the package form, be wrap-up 5 ' collect, therefore medium 6 ' tension variation can cause medium 6 ' elongation, and differential tension, the degree difference of medium 6 ' elongation.This unsettled elongation can cause medium 6 ' in when motion instability, thus stable tension must be arranged when printing continuous media, otherwise can cause the decline of print media quality.
Summary of the invention
Technical problem to be solved in the utility model is to keep (continuously) medium to have stable tension in print procedure, reaches the purpose of control (continuously) medium tension force.
The technical scheme that the utility model adopted is that an intermediate calender rolls is set between medium transport pressure roller and wrap-up, this intermediate calender rolls is outside the straight line line between medium transport pressure roller and the wrap-up, pressure sensor is installed on the intermediate calender rolls, be used for measuring the pressure that causes by medium tension force, so that control to intermediate calender rolls.
Pressure sensor of the present utility model links to each other with control device, and control device with furl motor and link to each other so that the signal input control device that pressure sensor produces, finally control the electric current of coiler motor.
The beneficial effects of the utility model are that the tension force of continuous media is under control, and can keep continuous media to have stable tension in print procedure, have improved the quality of print media.
Description of drawings
Fig. 1 is the structural representation of existing printer.
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 2, the utility model mainly contains unwinding device 1, slide rail 2, medium transport pressure roller 3, shower nozzle 4, intermediate calender rolls 7, pressure sensor 8, control device 10 and wrap-up 5 and forms, intermediate calender rolls 7 is between medium transport pressure roller 3 and wrap-up 5, and this intermediate calender rolls 7 is equipped with pressure sensor 8 at the two ends of intermediate calender rolls 7 outside the straight line line 9 between medium transport pressure roller 3 and the wrap-up 5; Control device 10 respectively with pressure sensor 8 with furl motor 11 and be connected.
During use, the print media 6 of ink-jet printer has a pressure to intermediate calender rolls 7 by intermediate calender rolls 7 time, the pressure sensor of installing at intermediate calender rolls 7 two ends 8 is used for measuring the pressure to intermediate calender rolls 7 that is caused by medium tension force, the signal input control device 10 that pressure sensor 8 produces, the electric current of control device 10 control coiler motors 11.If pressure is too small, expression medium tension force is too small, and control device 10 just strengthens the electric current that drives coiler motor 11, thereby tightens up print media 6, reaches the purpose that adds hightension; If pressure is suitable, expression print media 6 tension force are suitable, and control device 10 just keeps driving the electric current of coiler motor 11, keep the stable of tension force; If pressure is excessive, expression print media 6 overtensions, control device 10 just reduces to drive the electric current of coiler motor 11, reduces tension force thus.
Said print media 6 can be various paper, plastic foil, textile and other composite etc. in the present embodiment.
Claims (2)
1. one kind has the printer that tension force is controlled, it comprises unwinding device, slide rail, medium transport pressure roller, shower nozzle and wrap-up, it is characterized in that: between medium transport pressure roller (3) and wrap-up (5), an intermediate calender rolls (7) is set, this intermediate calender rolls (7) is equipped with pressure sensor (8) on the intermediate calender rolls (7) outside the straight line line (9) between medium transport pressure roller (3) and the wrap-up (5).
2. printer according to claim 1 is characterized in that: pressure sensor (8) links to each other with control device (10), and control device (10) links to each other with coiler motor (11).
