Abstract
The invention discloses a device used for automatically checking and adjusting the printing gap for a printer, comprising a CR frame arranged on a CR eccentric shaft. The eccentric centres at both ends of the CR eccentric shaft are pivotally connected with the printer support which is provided with a stepping motor, a drive gear set, a grating sheet, and a photoelectric sensor corresponding to the grating sheet; wherein, the drive gear set comprises a drive gear I, a drive gear II and a drive gear III; the grating sheet and the drive gear I are coaxially and fixedly arranged on the drive shaft of the stepping motor; the CR eccentric shaft is coaxially and fixedly provided with the drive gear III; the drive gear II is arranged between the drive gear III and the drive gear I. The device of the invention guarantees the accuracy and stability of the printing gap, thus greatly facilitating the users in operation, effectively guaranteeing the printing gap of the printer and guaranteeing the quality and the service life of the printer. Therefore, the device can be widely applied into checking the adjusting the printing gap for the printer.
Description
Technical field
A kind of printer that the present invention relates to is a kind of automatic checking and regulating device at printing interval of printer specifically.
Background technology
Present existing impact printer, the adjusting of its printing interval generally all are to draw the rotation of word car eccentric shaft by stirring the manual adjustments driving lever, being with, thereby band draws the lifting of word vehicle frame, and reach predefined paper sheet thickness gear.But for different types of paper, thickness all changes, and what the user will be frequent like this stirs the manual adjustments driving lever with hand, causes the user inconvenient greatly.And because the difference of paper quality also can cause actual (real) thickness to be difficult to practical problems such as corresponding with paper connection number.Regulate the operation of printing interval of printer by stirring the manual adjustments driving lever to predefined paper sheet thickness gear like this, just will be difficult to the paper sheet thickness of corresponding actual required printing.Tend to make printing interval bigger than normal or less than normal like this, thereby directly have influence on the quality of printing, make printing effect light partially smudgy (printing interval is bigger than normal), or cause printhead card colour band (printing interval is less than normal).These all can have influence on the service property (quality) and the service life of printer.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of effective service property (quality) of printer and automatic checking and regulating device at printing interval in service life of having ensured.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of automatic checking and regulating device at printing interval of printer, it comprises the word vehicle frame that is installed on the word car eccentric shaft, the eccentric pivot at described word car eccentric shaft two ends is connected on the printer stand, described printer stand is provided with stepper motor, driving gear set, lenticular lenses and with the lenticular lenses corresponding photoelectric sensor, described driving gear set comprises travelling gear I, travelling gear II, travelling gear III, described lenticular lenses and travelling gear I be coaxial to be fixedly mounted on the power transmission shaft of stepper motor, the coaxial travelling gear III that is fixed with of described word car eccentric shaft is provided with travelling gear II between described travelling gear III and the travelling gear I.
The invention has the beneficial effects as follows: the present invention is because each detection all requires the word vehicle frame to touch paper, so detected paper sheet thickness all is the actual (real) thickness of paper, the word vehicle frame goes back up to the printing interval height of software set then, thereby the correctness and the stability of printing interval have been guaranteed, therefore can greatly facilitate user's operation, and effectively guarantee the printing interval of printer, ensured the service property (quality) and the service life of printer, thereby can be widely used in printing interval of printer detection and the adjusting.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is stepper motor of the present invention and parts scheme of installation thereof;
Fig. 3 is a travelling gear III scheme of installation of the present invention.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of automatic checking and regulating device at printing interval of printer, it comprises the word vehicle frame 6 that is installed on the word car eccentric shaft 1, the eccentric pivot at described word car eccentric shaft 1 two ends is connected on the printer stand 2, described printer stand 2 is provided with stepper motor 3, driving gear set 4, lenticular lenses 5 and with lenticular lenses 5 corresponding photoelectric sensor 51, described driving gear set 4 comprises travelling gear I41, travelling gear II 42, travelling gear III 43, described lenticular lenses 5 and travelling gear I 41 be coaxial to be fixedly mounted on the power transmission shaft 31 of stepper motor 3, the described word car eccentric shaft 1 coaxial travelling gear III 43 that is fixed with is provided with travelling gear II 42 between described travelling gear III 43 and the travelling gear I 41.
Certain needs according to reality; be not limited to be provided with a travelling gear II 42 between travelling gear III 43 and the travelling gear I 41; also several driving gear set can be set, reach technique effect of the present invention with essentially identical means in a word, all should belong to protection scope of the present invention.
The operation principle of this product is: stepper motor 3 drives driving gear set 4 makes word car eccentric shaft 1 rotate, thereby traction word vehicle frame 6 is done upper and lower moving.When word vehicle frame 6 moves down into paper, be subjected to hindering and continue to descend, cause stepper motor 3 to occur skidding, detect this variation by lenticular lenses 5 and photoelectric sensor 51, driving by control system again, make word vehicle frame 6 rise to the clearance height of software set, thereby guaranteed the correctness and the stability of printing interval.
The present invention is because each detection all requires word vehicle frame 6 to touch paper, so detected paper sheet thickness all is the actual (real) thickness of paper, word vehicle frame 6 goes back up to the printing interval height of software set then, thereby the correctness and the stability of printing interval have been guaranteed, therefore can greatly facilitate user's operation, and effectively guarantee the printing interval of printer to have ensured the service property (quality) and the service life of printer, thereby can be widely used on printing interval of printer detects and regulate.
