Abstract
The utility model relates to an improved one-way drive member that is used in binary paper system of digital printing machine, which comprises a drive shaft (2) arranged on fixed plate (1); a rotational binary paper tooth plate (3) arranged on fixed plate (1); a binary paper gear (4) arranged on the drive shaft (2) and meshed with binary paper tooth plate. The structure of binary paper gear (4) arranged on drive shaft (2) is: one end of the drive shaft (2) nests a one way bearing (5); the one way bearing is embedded in the binary paper gear (4) and can drive the binary paper gear (4) following with the one way bearing (5). For the substitution of one-way torsion spring into one way bearing, the one way bearing not only guarantees flexible drive, good one way performance, but also overcomes the disadvantages of the torsion spring being easy to break after prolonged using.
Description
Technical field
The utility model belongs to the technical field of duplicating machine, relates in particular to a kind of improved duplicating machine two paper feed system one-way driving mechanisms that are used for.
Background technique
Shown in Fig. 4～5, existing integrated duplicating machine (mimeograph a kind of) all has two paper feed systems, one-way driving mechanism in this two paper feeds system generally comprise the transmission shaft 1 that is located on the fixed plate ', the rotatable two paper feed tooth plates that are arranged on the fixed plate, and one be arranged on transmission shaft 1 ' go up and and two paper feed tooth plates be meshed two paper feed gears 2 ', two paper feed tooth plates then link to each other with a series of transmitting assembliess, for the purpose that two paper feeds are carried out smoothly, what two paper feed gears needed is one way engagement, for this reason two paper feed gears 2 ' and transmission shaft 1 ' between be provided with a unidirectional torsion spring 3 ', this two paper feed gears 2 ' and transmission shaft 1 ' between be provided with unidirectional torsion spring 3 ' structure be routine techniques, unidirectional drive mechanism in the above-mentioned two paper feed systems is a prior art, and its unidirectional drive mechanism in the two paper feed systems that claimant oneself has sold on market is identical.
As a patent No. is a kind of duplicating machine one paper feed driving mechanism so the Chinese utility model patent " duplicating machine one paper feed driving mechanism " of ZL02215952.5 (notification number is CN2526173Y) has just disclosed, it is characterized in that this mechanism includes a paper feed switch base, seat is provided with oilite bushing and oil-containing axle bed, one paper feed minor axis is bearing in wherein, axle is provided with the paper feed small gear with the engagement of adjacent component one paper feed tooth plate, ratchet, the check spring, the check spring of one paper feed minor axis one-way rotation closely is sleeved on a paper feed small gear and the paper feed minor axis, check spring elbow is inlaid in the ratchet slot, ratchet is sleeved on again outside the check spring, paper feed small gear and ratchet are made axial limiting by jump ring on the axle and liner simultaneously, one paper feed minor axis links to each other with stranding paper major axis with pin by connecting sleeve simultaneously, with the ratchet interlock be lever-type ratchet, it is a rotating fulcrum with the pawl base on the support axle, the support axle is fixed on the paper feed switch base, be provided with the ratchet extension spring between a ratchet and the paper feed switch base, the other end of ratchet links to each other with magnetic core, and the electromagnet that it is fixed on the paper feed switch base is switched on and adhesive.This patent has just disclosed the purpose that realizes making paper feed minor axis (transmission shaft) one-way rotation by check spring (unidirectional torsion spring).
Realize making the defective of paper feed minor axis (transmission shaft) one-way rotation to be by check spring (unidirectional torsion spring): unidirectional torsion spring in use between long its not only can lose the unidirectional function of reversing and lost efficacy, even rupture easily and damage, cause whole duplicating machine not use, need maintenance significantly.
At above-mentioned reason, existing world support also can improve further.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of improved duplicating machine two paper feed system one-way driving mechanisms that are used for fragile and not simple in structure at above-mentioned prior art present situation, and this driving mechanism has also that user cost is low, the advantage of easy assembling.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of improved duplicating machine two paper feed system one-way driving mechanisms that are used for, include the transmission shaft that is located on the fixed plate, rotatable be arranged on two paper feed tooth plates on the fixed plate, and one be arranged on the transmission shaft and and two paper feed tooth plates, the two paper feed gears that are meshed, it is characterized in that the structure that described two paper feed gears are arranged on the transmission shaft is: be nested with a unilateral bearing at transmission shaft one end, this unilateral bearing then is embedded in two paper feed gears and can drives two paper feed gears and plays rotation with one.
Compared with prior art, advantage of the present utility model is: it replaces the function of original unidirectional torsion spring with unilateral bearing, because unilateral bearing is compared with unidirectional torsion spring and had that can to protect positive drive flexible, one-way is good, can overcome the button spring again and grow disconnected easily advantage service time; Only need during assembling unilateral bearing is set on the transmission shaft, two paper feed gears tightly are nested on this unilateral bearing get final product again, assemble simply so also have.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
A kind of improved duplicating machine (mimeograph a kind of) two paper feed system one-way driving mechanisms that are used for shown in Fig. 1～3, include the transmission shaft 2 that is located on the fixed plate 1, rotatable be arranged on two paper feed tooth plates 3 on the fixed plate 1, and one be arranged on the transmission shaft 2 and and two paper feed tooth plates 3, the two paper feed gears 4 that are meshed, two paper feed tooth plates 3 link to each other with a series of transmitting assembliess 6, this transmitting assemblies 6 can adopt the existing transmitting assemblies that is used for duplicating machine, and it is identical with unidirectional drive mechanism in the two paper feed systems on the duplicating machine that claimant oneself has sold on market;
As shown in Figure 3, the structure that described two paper feed gears 4 are arranged on the transmission shaft 2 is: be nested with a unilateral bearing 5 at transmission shaft 2 one ends, this unilateral bearing 5 then is embedded in two paper feed gears 4 and can drives two paper feed gears 4 and plays rotation with one, unilateral bearing 5 is a standard piece, can buy according to the model of transmission shaft 2.
Working principle of the present utility model is identical with two paper feed systems on the existing duplicating machine, drive two paper feed tooth plates 3 by transmitting assemblies and rotate, two paper feed gears 4 on the transmission shaft 2 rotate again, under the effect of unilateral bearing 5, transmission shaft 2 unidirectional transmissions are to realize the purpose of two paper feeds.
