Description
Technical field
A kind of counting gear resetting structure the utility model relates to cartridge, in particular on a kind of cartridge.
Background technique
Counting gear counting on the printer of existing market recognizes machine process and is：The cartridge more renewed on a printer
Afterwards, printer driver gear rotates, and drives counting gear rotation by the gear train assembly on cartridge, then passes through counting
Top foot on gear dials the counter switch of printer.And most of current counting gear is all only less than big half-turn tooth
Shape, counting gear rotates the position-limit foot being arranged thereon after half-turn and blocks, so that a fixing card dead position is parked in, at this point, counting
Gear top top foot plays the counter switch of printer surely, recognizes machine completion, and machinery panel green light is lighted, and equipment is in ready.
When printer cartridge service life exhausts, machinery panel amber light is lighted, at this time the bright cartridge represented in printer of amber light
Service life has use up, and cannot be further continued for printing, and cartridge must take out from printer at this time, carbon dust is added, and reset counting gear
It can be printed to initial position.
In the prior art, counting gear can be parked in a fixing card dead position after the completion of counting, when printer carbon dust and
When service life exhausts, after rejoining carbon dust, print job can just be continued by needing to recognize again by counting gear machine, and
Since counting gear is after recognizing machine for the first time, it is parked in a fixing card dead position, machine is recognized again and gear end cap is then needed to take out, then
Counting gear could be completed by, which reinstalling, recognizes machine, this not only troublesome in poeration, but also wastes time, in order to solve this problem,
Instantly there are Some Enterprises to accomplish not need to tear open counting gear and counting can be completed recognize machine, but occurred a new skill again
Art problem, precisely due to the shape and structure of original counting gear is considerably complicated, the market in face of being full of competitiveness, people are to substance
Cost performance demand it is bigger, and counting gear instantly is unfavorable for product in market since the cost in processing and forming is excessive
On competition get the mastery.
Utility model content
In view of the deficiencies of the prior art, the purpose of this utility model is to provide the counting gear resets on a kind of cartridge

Specific embodiment
In order to make the technical problems, technical solutions and advantages to be solved by the utility model clearer, below in conjunction with attached drawing
And specific embodiment is described in detail.
As shown in Figure 1, the counting gear resetting structure on a kind of cartridge of the utility model, including mounting post 1, setting exist
One end of powder cabin main body can install counting gear 2；Counting gear 2 is set in the mounting post 1, and counting gear 2 is by cartridge
Sliding tooth wheel drive, the excircle tooth of the counting gear 2 and driving gear engaged transmission；Gear end cap 3, is fixed on powder cabin
The end of main body；Wherein, the counting shift fork 4 for driving it to rotate is equipped in the end of the counting gear 2, in the counting gear
It is equipped with elastomeric element 5 that can be isolated with shift fork 4 is counted by the counting gear 2 between 2 and counting shift fork 4, is dialled in described count
Fork 4 is equipped with restriction protrusion 41, is equipped with and cooperates with the restriction protrusion 41 to limit described count and dial on the gear end cap 3
The limited section 31 of starting and final position that 4 control counting gear 2 of fork rotates.
In conjunction with Fig. 2 and Fig. 3, the limited section 31 includes the cylindrical body 311 being located on gear end cap 3, in the cylindrical body
311 inner wall is equipped with the annular retaining ring 312 to match with the counting shift fork 4, and the annular retaining ring 312 is equipped with a notch
313, block 314 is equipped on the notch 313, one end of the block 314 and the annular retaining ring 312 forms locking groove
315, the locking groove 315 is to count shift fork 4 to control the termination positive stop end that counting gear 2 rotates, in the annular retaining ring 312
The other end is equipped with a recess portion 316, and the recess portion 316 is that the counting shift fork 4 controls the starting positive stop end that counting gear 2 rotates.
To make the restriction protrusion 41 be able to achieve better rotation on the recess portion 316, the recess portion 316 along described
One end of 315 direction of rotation of locking groove is the smooth ramped shaped in surface；One end of the recess portion 316 is inclined surface, for blocking
The restriction protrusion 41 prevents from counting the rotation of 4 opposite direction of shift fork.
Further, the rotation for counting shift fork 4 and controlling the counting gear 2 is realized, at the end of the counting gear 2
Portion is equipped with the cylinder 21 with ratchet, the cylinder 21 perpendicular to the counting gear 2 end face, and the ratchet be set to it is described
The end of cylinder 21, it is described count shift fork 4 end be equipped with elastic component 6 (and elastic component can with count shift fork can together at
Type), the end for counting shift fork 4 is equipped with multiple positioning columns 42, and the multiple and positioning column 42 is equipped on the elastic component 6
One-to-one location hole 62 has multiple be embedded on the cylinder 21 to the cylinder 21 bending on the elastic component 6
Elastic slice 61 between helical teeth.In conjunction with Fig. 4, in the counting gear 2 rotation, described in the ratchet drive on the counting gear 2
61 rotary motion of elastic slice so that elastic component 6 be driven to rotate, and then rotates counting shift fork 4 on limited section 31.
It counts in the present case and recognizes machine process and be：Driving gear band on cartridge moves counting gear 2 and rotates, counting gear 2
Rotary force is transferred on elastic component 6 by the cooperation of ratchet and the elastic slice 61 in its main body 21, due to the elastic component 6
It is fixedly connected on described one end for counting shift fork 4, is driven when no doubt the elastic component 6 rotates and counts the rotation of shift fork 4, the counting
Then shift fork 4 makes it turn to the stop on being located at the recess portion 316 (starting positive stop end) at first by rotation
On slot 315 (terminating positive stop end), elastomeric element 5 is separated the counting gear 2 with elastic component 6 by elastic force at this time, i.e., by institute
It states and counts in the pop-up to the locking groove 315 of shift fork 4, then the top foot counted on shift fork 4 dials the counting on printer
Motor-driven complete is recognized in switch, counting.Counting shift fork 4 and 2 onrelevant of counting gear after the completion of recognizing machine is counted to move, it is described
Counting shift fork 4 can normally rotate a certain angle, and the counting gear 2 does not rotate, can only be by the driving gear on cartridge
It drives, when needing replacing carbon dust, cartridge is taken out, carbon dust is then added, carbon dust, which needs to count again after adding, recognizes machine, phase
To the prior art, recess portion 316 is turned to another advantage is that not needing to dismantle gear end cap and can will count shift fork 4 in this case
On (starting positive stop end), it is only necessary to press the rotation of counting shift fork 4 to the recess portion 316 (starting positive stop end), then carbon
Powder box is installed on a printer, is completed to count again and is recognized machine.
The utility model, structure is simple, and machine-shaping is simple, at low cost, easy to operate, recognizes machine process band for repeat count
To facilitate.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art can readily occur in variation in technical scope disclosed by the utility model
Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with the power
Subject to the protection scope that benefit requires.
