Abstract
The utility model provide a kind of in the same way, the pickup roller set of synchronous, synchronized rotation, comprise the driving gear be connected with motor output shaft, first, second driven gear be connected with two pickup roller shafts respectively, it is characterized in that the driving gear be connected with motor output shaft is between first, second driven gear, and first, second driven gear is meshed with driving gear respectively by first, second travelling gear.Achieve synchronously, in the same way, the requirement of synchronized rotation, make multiple pickup rollers on two pickup roller shafts and wheel shaft in the same way, synchronous, synchronized rotation, thus evenly rubbing printing paper normotopia moves, and print quality is protected.Reduce associated gear, the kind of part and quantity to greatest extent simultaneously, reduce costs, simplify structure.
Description
Technical field
The utility model relates to a kind of pickup roller set, especially a kind of impact printer in the same way, the pickup roller set of synchronous, synchronized rotation, belong to printer Design and manufacturing technology field.
Background technology
Pickup roller is a main components of impact printer, make print media in printer, carry out the movement of longitudinal direction by this roller, so that after moving combine with the transverse direction of needle type print head, print needing the content printed in any position of print media.The pickup roller of prior art completes rolling usually under the driving of a motor, and the pickup roller that existing printer has two rows above.Therefore, how to ensure that the above pickup roller of two rows can move according to same fast rubbing print media normotopia of rolling, avoiding occurring printing, departing from the print quality problems such as desired location because misplacing mobile, is an emphasis of pickup roller structure design.Existing impact printer normally by motor, drive, driving-belt by power transmission on the pickup roller shaft of two or more rows.Such kind of drive easily because of drive belt slip or tension force inconsistent and cause two rows and above pickup roller thereof to exist to roll speed poor, and then cause print media dislocation and affect print quality.Therefore, be necessary to be improved prior art.
Summary of the invention
From the angle of overall design, for improving print quality to greatest extent, simplifying structure, the utility model proposes a kind of in the same way, the pickup roller set of synchronous, synchronized rotation.
The utility model is realized by following technical proposal: one in the same way, synchronously, the pickup roller set of synchronized rotation, comprise the driving gear be connected with motor output shaft, be connected with two pickup roller shafts respectively first, second driven gear, it is characterized in that the driving gear be connected with motor output shaft is positioned at first, between second driven gear, and first, second driven gear is respectively by first, second travelling gear is meshed with driving gear, so that under driving gear drives, drive first, second travelling gear and first, second driven gear synchronous axial system, again by first, second travelling gear engages with driving gear, and first, second driven gear is respectively with first, the engagement of the second driven gear, realize first, the rotating in same direction of the second driven gear, make multiple pickup rollers on two pickup roller shafts and wheel shaft in the same way, synchronous axial system.
First, second travelling gear described is identical with the speed ratio of first, second driven gear, so that under driving gear drives, realizes the synchronized rotation of first, second travelling gear and first, second driven gear.
The utility model compared with prior art has following advantages and effect: adopt such scheme, namely the driving gear and first by being connected with motor output shaft, the engagement of the second travelling gear, again by first, second travelling gear is respectively with first, the engagement of the second driven gear, achieve synchronous, the requirement of rotating in same direction, add first, second travelling gear and first, the speed ratio of the second driven gear is identical, achieve the requirement of synchronized rotation, make multiple pickup rollers on two pickup roller shafts and wheel shaft in the same way, synchronously, synchronized rotation, thus evenly rubbing printing paper normotopia moves, print quality is protected.Reduce associated gear, the kind of part and quantity to greatest extent simultaneously, reduce costs, simplify structure.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
The utility model provide in the same way, the pickup roller set of synchronous, synchronized rotation, comprise the driving gear 4 be connected with motor output shaft, first, second driven gear 1,6 be connected with two pickup roller shafts 2,7 respectively, the driving gear 4 be wherein connected with motor output shaft is between first, second driven gear 1,6, and first, second driven gear 1,6 is meshed with driving gear 4 respectively by first, second travelling gear 3,5.So that under driving gear 4 rotates clockwise, drive first, second travelling gear 3,5 to make inhour synchronously, in the same way and rotate, then drive first, second driven gear 1,6 synchronously, in the same way to rotate clockwise; Vice versa.First, second travelling gear 3,5 described is identical with the speed ratio of first, second driven gear 1,6, thus under driving gear 4 drives, realizes the synchronized rotation of first, second travelling gear 3,5 and first, second driven gear 1,6.Make multiple pickup rollers on two pickup roller shafts 2,7 and wheel shaft 2,7 in the same way, synchronous, synchronized rotation.
Claims (2)
