Description

Automatic book leaf turner

Technical field

The utility model relates to a kind of automatic book leaf turner, is specifically related to a kind of frame for movement that realizes turning over the book function by circuit control.

Background technology

Along with the progress and the development of science and technology in epoch, people not only rest on the material life of enriching them to the concern of disadvantaged group, and are deep into the spiritual need that how to satisfy them.For the friends of both hands deformity, it is very difficult wanting to read a book.Equally, for the bound wounded of both hands, play music commander or player, turning over the so simple action of book also becomes a very inconvenient thing.So book leaf turner should need and give birth to automatically.The automatic book leaf turner of formally coming at present market is few in number, and all exists cost an arm and a leg, inconvenience is carried or insecure drawback of working, and therefore needs a kind of inexpensive, portable, working stability, easy to operate automatic book leaf turner newly of design.

Chinese patent ZL99222849.2 discloses the automatic book leaf turner of a kind of cam, connect transmission case by micromotor, transmission case connects bevel gear and cam, bevel gear connects twists with the fingers paper web, twists with the fingers the paper web top sth. made by twisting paper bowl is set, and twists with the fingers and studs with little shape thorn on the paper bowl periphery, twisting with the fingers the tooth that pulls out that studs with distribution according to certain rules on the paper web periphery, twisting with the fingers in the paper web has piston rod, connecting rod, bullet paper bar and back-moving spring, stings and pulls out tooth page has been dialled by little shape, by playing the paper bar page is bound to another side again.Its complicated integral structure, cost are higher relatively.

The viscosity of Chinese patent ZL200620074756.1 by adhesive tape takes up page and realizes turning over the book function, for guaranteeing the reliable and stable of work, need whenever turn over a page and upgrade one section adhesive tape, thereby produce a large amount of discarded adhesive tapes, the step of upgrading adhesive tape also makes the design complexity of mechanical part.

Summary of the invention

The purpose of this utility model is to provide the automatic book leaf turner that a kind of work is more reliable and more stable, structure is simpler, price is more cheap.

Automatic book leaf turner of the present utility model, comprise and pinch mechanism of paper 23, page turning arm 17 and transmission system separately, the page turning arm can rotate around the axis, pinch mechanism of paper and be positioned at the upper end of page turning arm, wherein: the described mechanism of paper of pinching comprises that two are in contact with one another and the

friction pulley

1,2 of backscrolling, and described friction pulley surface is an elastomeric material.

The utility model is the friction pulley of being in contact with one another of rubber, backscrolling by two surfaces, anthropomorphic dummy's finger pinch the paper action, successful design goes out simple in structure, the automatic book leaf turner of stable and reliable operation also greatly reduces the production cost of book leaf turner simultaneously.

Automatic book leaf turner of the present utility model, wherein: described pinch paper structure also comprise near each friction pulley and with the scraping blade of friction pulley coaxial rotation wheel 5,6, the axle of described scraping blade wheel is provided with radiation shape projection, each projection is provided with scraping blade 10, described scraping blade and projection are the θ angle, 90 °≤θ＜180 °, described scraping blade free-end is made the radius of the radius of circular motion greater than friction pulley.

Link to each other by elasticity hinge A between described scraping blade and the projection.

The friction pulley of described two backscrollings drives counter-rotational two

gears

7,8 by worm screw 12 and drives.

Described worm screw is driven by non-circular shaft.

The driving crank 18 coaxial with described page turning arm links to each other with its power crank 15 with spring 16.

The installation of the automatic book leaf turner of the utility model and working method can be carried out in the following manner:

As shown in Figure 7, the mechanical part of book leaf turner is installed the centered beneath position of holding book plate 22 in the drawings, so that book leaf turner can turn over book by both direction, 23 for pinching mechanism of paper among the figure, and 17 are the page turning arm.

Page turning arm 17 can make the friction pulley of pinching mechanism of paper 23 can touch the page on both sides by clockwise, both direction swing counterclockwise under the effect of motor.The wherein beginning of page turning arm 17, the manner of execution of pinching mechanism of paper 23, action and finish to control automatically by correspondent control circuits, being controlled at this and not doing detailed description of circuit, only the course of action to mechanical part describes.

The course of action that turns over one page paper left is as follows:

1. page turning arm 17 swing to the right earlier makes and pinches mechanism of paper 23 and can touch books right side page to be turned over, and page turning arm 17 stops action;

2. pinch mechanism of paper 23 then and do and pinch paper action, will treat that leaf through a book pinched, pinch mechanism of paper 23 and stop to move;

3. page turning arm 17 is swung left, makes simultaneously to be pinched mechanism of paper 23 and pinch and treat that leaf through a book translates into the left side, and when pinching mechanism of paper 23 and touching books left sides page, page turning arm 17 stops action;

4. pinch the page relieving that mechanism of paper 23 backward rotation will be pinched, pinch mechanism of paper 23 and stop action; So far, once turn over the book release.

This mechanism is symmetrical, and the process of stirring one page paper to the right is identical with the page turning process left of the above, and just direction is opposite.

The utility model beneficial effect is:

1. use two rubber wheels to rolling, cooperate with two scraping blades wheel simultaneously and simulate action that two fingers pinch page and realized accurate control page.

2. scraping blade makes the radius of the inswept radius of a circle of scraping blade greater than friction pulley in the elasticity hinge design of corner, can prolong scraping blade operating distance on paper, simultaneously paper is not caused damage.

3. drive the worm screw that friction pulley rotates and adopt non-circular hole, the through-drive that the available cross-section shape is corresponding with it also can be pinched the position of mechanism of paper on the page turning arm according to the adjusting of the flexible in size of books breadth simultaneously.

4. realize neatly automatically the book that turns over of the right and left page is operated by the page turning arm that sways.

5. link to each other with its power crank with spring with the coaxial driving crank of page turning arm, impact that can the kicking motion process is simultaneously for providing collectable displacement signal in the course of work.

6. the action of pinching mechanism of paper and page turning arm by touch switch and automatic control circuit control makes that action control is accurate and simple to operate.

7. the utility model is simple in structure, cost is low, be easy to carry.
