The utility model has the advantages of simple structure, convenient installation and low making cost.
Description
Technical field
The utility model relates to a kind of driving mechanism of reversing of preventing, relates in particular to the anti-transmission device that reverses of a kind of timing rubber roll.
Background technique
The anti-transmission device that reverses of existing timing rubber roll only is provided with one-level check torsion spring, and the purpose that the check torsion spring is set is to make the unidirectional running of direction that it as far as possible can only be as requested, increases the Location accuracy of paper, makes the paper of the manuscript paper that prints out measure-alike.But when it runs up, still there is the rotation of its small direction, causes the location of paper inaccurate, make the position of the literal of beginning and last printing that bigger difference be arranged, promptly locate inaccurately, even literal is printed on the manuscript paper fully.
Summary of the invention
The utility model is at the existing in prior technology deficiency, and provide a kind of timing rubber roll that adopts two-stage to prevent reversing gearbox the anti-technological scheme that reverses transmission device, its anti-better effects if that reverses, the paper Location accuracy is higher, can reach when using 100 manuscript paper of the utility model printing, manuscript paper after first printing is controlled within the 0.1mm with the error of the paper of the manuscript paper of last printing, and the utlity model has simple in structure, easy for installation, advantage of low manufacturing cost.
The utility model is realized by following technical measures: it comprises the small gear that connects with drive unit, small gear is fixedly connected with axle sleeve, small gear and axle sleeve are sleeved on the one-level step axle and the location of stepped timing rubber roll power intake, the diameter of the two stage steps axle of the external diameter of axle sleeve and adjacent rubber roll input end is suitable, axle sleeve and the stressed joint of two stage steps axle, and be set with one-level check torsion spring thereon, three grades of step axle places at the rubber roll input end are equipped with bearing, be set with the secondary check torsion spring identical with one-level check torsion spring rotation direction in the outside of bearing, the left end of secondary check torsion spring upwards stretches and connects firmly with the machine front side plate.
Above-mentioned one-level check torsion spring and secondary check torsion spring are left-handed torsion spring.The rotation direction of torsion spring can be chosen as required, and so regularly the installation of rubber roll is relevant with sense of rotation.
The internal diameter of above-mentioned one-level check torsion spring is less than the external diameter of axle sleeve.Transmitting torque so better.
Above-mentioned small gear and the engagement of the elevating arc of drive unit.Such mechanical transmission reliable in action, the sequential between each action is accurate, error free.
The length of above-mentioned one-level check torsion spring is corresponding with the total length of axle sleeve and two stage steps axle.Guaranteed that like this driving moment that the elevating arc transmission comes is applied to regularly on the rubber roll reliably.
The left end of secondary check torsion spring extends upward the back and forms a positioning ring, and is fixed on front side plate top by fastening screw trip bolt and cover, and wherein fastening screw trip bolt passes to overlap and is fixed on the front side plate, and the thickness of cover is corresponding with the length of secondary check torsion spring.This means of fixation is simple and reliable, prevents that regularly rubber roll produces reverse when high speed printing, has guaranteed the paper accurate positioning.
The beneficial effect of this programme can be learnt according to the narration to such scheme, the anti-technological scheme that reverses transmission device of the timing rubber roll of the anti-reversing gearbox of two-stage, its anti-better effects if that reverses, the paper Location accuracy is higher, can reach when using 100 manuscript paper of the utility model printing, manuscript paper after first printing is controlled within the 0.1mm with the error of the paper of the manuscript paper of last printing, and the utlity model has simple in structure, easy for installation, advantage of low manufacturing cost.
