Description
Technical field
The present invention relates to the paper sheet positioning mechanism in a kind of document feeder.
Background technology
Document feeder is a kind of device for automatic transport paper, and it is right that it comes in paper is transported to the devices such as drawing folding machine one by one
Paper is for further processing, and is typically provided with after placing paper on sheet holding member paper is carried out horizontal stroke in document feeder
To the paper sheet positioning mechanism of location, after paper is placed on sheet holding member, typically require that paper is positioned in the center of sheet holding member
Position, above-mentioned detent mechanism generally comprises the baffle plate that two block gaps are arranged, and two pieces of baffle plates are separately positioned on the longitudinal direction of sheet holding member
The both sides of center line, two pieces of baffle plates all can slide laterally, and after placing paper on sheet holding member, makes two pieces of baffle plates to phase
To direction transverse shifting, make two pieces of baffle plates clamp paper, make paper be laterally positioned.Above-mentioned paper sheet positioning mechanism is logical
Cross and move two pieces of baffle plates respectively and make two pieces of baffle plates clamp paper, after moving two pieces of baffle plates respectively, it is impossible to ensure two pieces
The position at baffle plate place is symmetrical about the longitudinal centre line of sheet holding member, and this is easy for so that two pieces of baffle plates are by paper clamping position
After, two pieces of baffle plates are not about the longitudinal centre line symmetry of sheet holding member, and this allows for paper and is not located at sheet holding member
Center, this will make the position of paper produce deviation so that document feeder is by paper sheet delivery to the devices such as drawing folding machine
Rear next step carried out process for producing deviation.
Summary of the invention
The technical problem to be solved is to provide the defeated original text of the center that paper can be accurately positioned sheet holding member
Paper sheet positioning mechanism in device.
For solving above-mentioned technical problem, the paper sheet positioning mechanism in the document feeder that the present invention provides, including:
Sheet holding member；
Parallel two long slot bore being horizontally installed on sheet holding member；
It is arranged on the upper surface of sheet holding member and relatively can slide along two long slot bores and relative to the longitudinal centre line of sheet holding member
Symmetrically arranged two pieces of baffle plates；
Being provided with two Mobile bases being connected with two pieces of baffle plates respectively on the lower surface of described sheet holding member, two Mobile bases are equal
Connect and have a tooth bar, between two Mobile bases, be provided with a rotating gear, two tooth bars respectively with the both sides phase of gear
Engagement；
Be provided with two parallel slide bars on the lower surface of described sheet holding member, two Mobile bases all include respectively with two
Two sliding seats that sliding bar coordinates, two pieces of baffle plates all connect, often by long slot bore is fixing with two corresponding sliding seats
Two sliding seats in individual Mobile base are all connected by connecting plate, and one end of two toothed rack is respectively fixedly connected with in two pieces of companies
On fishplate bar；
The position of the close gear of the lower surface of sheet holding member is provided with gripper shoe, and two slide bars all wear on the supporting plate.
After using above structure, the present invention compared with prior art, has the advantage that
In the present invention, two pieces of baffle plates are connected with two Mobile bases respectively, and two Mobile bases are connected with two toothed rack respectively, and two
Toothed rack engages with the both sides of same gear so that when the mobile two pieces of baffle plates of needs, two pieces of baffle plate sync directions move,
After placing paper on sheet holding member, one of baffle plate, between two pieces of baffle plates, is promoted by paper to paper orientation,
Now another block baffle plate moves with this baffle plate synchronous backward so that two pieces of baffle plates are all the time relative to the longitudinal centre line of sheet holding member
Symmetry, after two pieces of baffle plates are by paper clamping position, paper is accurately positioned the center of sheet holding member so that document feeder
Will not Production deviations by next step process carried out rear in paper sheet delivery to the devices such as drawing folding machine.

Detailed description of the invention
With detailed description of the invention, the present invention is described in more detail below in conjunction with the accompanying drawings.
By shown in Fig. 1 to Fig. 5, the paper sheet positioning mechanism in document feeder of the present invention, including sheet holding member 1, it is horizontally installed on
Parallel two long slot bore 101 on sheet holding member 1, be arranged on sheet holding member 1 upper surface and can be along two long slot bores 101
Relatively sliding and two piece baffle plates 2 symmetrically arranged relative to the longitudinal centre line of sheet holding member 1, wherein in Fig. 2, A is and puts
The longitudinal centre line of paper platform 1, two long slot bores 101 are divided into two sections, say, that two long slot bores 101 all can be divided into
It is arranged on the first long slot bore of the side of the longitudinal centre line of sheet holding member 1 and is arranged on longitudinal centre line another of sheet holding member 1
Second long slot bore of side, the first long slot bore in same long slot bore 101 and the second long slot bore are on the same line.
Two Mobile bases 3 being connected respectively, two shiftings it are provided with two pieces of baffle plates 2 on the lower surface of described sheet holding member 1
Dynamic seat 3 is respectively connected with a tooth bar 4, is provided with a rotating gear 5 between two Mobile bases 3, two tooth bars 4 points
It is not meshed with the both sides of gear 5, the lower surface of sheet holding member 1 is provided with a fixed plate 6, fixed plate 6 and sheet holding member
Leaving spacing between the lower surface of 1, gear 5 is rotating to be arranged in fixed plate 6, gear 6 be positioned at fixed plate 6 with
