Three, technical characterictic and operation principle:

Printer is installed on the terrace rail of beam-and-rail factory production line roller groove one side, arranges with roller fluted shaft line parallel.Movable cantilever 4 grades are stretched to roller groove center top.By the axially-movable of holder car 1 and the transverse movement of rocking arm stand 2, realize and the basic contraposition of supplied materials and separating of character head.Rocking arm stand 2 is connected with movable cantilever 4 usefulness horizontal hinge, oscillating cylinder 3 helps the coaster 5 usefulness slide rails under basic contraposition, movable cantilever 4 and the arm to be connected with the amplitude of oscillation of an angle of 90 degrees degree, coaster 5 and four connecting rod cylinders 6, connecting rod pendulum 7, character arm 8, character cylinder 10, character head 9.A.H (two kinds of specifications); And positioning and guiding groove 32, etc. the corresponding cooperation of work structuring.Realize accurate contraposition and effectively printing.Its technological process is that supplied materials stops--contraposition--print--return---supplied materials stops replacing character--the circumference steel transports--, the technological requirement of going round and beginning again, realization is accurately located and effective the printing automatically.

Complete machine in length and breadth after move realizing basic contraposition, by oscillating cylinder 3, movable cantilever 4, sliding hammer 5, character arm 8, character arm cylinder 10, (the vertical contraposition of flexible realization of character arm cylinder 10) character head 9, positioning and guiding groove 23, fine setting accurately locate.Its fine setting positioning principle is: positioning and guiding groove 23 (shape and tangent plane size according to the fork-like farm tool used in ancient China supplied materials are dovetail groove or flared channels), contact with supplied materials gradually, the friction counter-force of quickenings, the guiding coaster that passes to 5 also increases thereupon, forces coaster 5 laterally to horizontally slip, positioning and guiding groove 23 is just accurately located voluntarily at this moment along with the amplitude of oscillation of character arm 8 is pushed the speed and produced the friction counter-force.Be located at stroke Closing Switch 33 on the character head 9AH after locating and send the printing of can dropping hammer of sound and light signal, signal driver.Again because four connecting rod cylinders 6, connecting rod pendulum 7, coaster 5, the displacement of character arm 8 is identical, so the strike character is not only fast but also accurate.The water of cooling water pipe 15 and tracheae 16 and compressed air are by the workshop pumping plant, and the wind station is supplied with.

Character head 9 has two kinds of versions: i.e. A type and H type.The A type is the adjustable plate chain type, and it is by character frame 24, character 25, character key 26, star tooth connection wheel 27, sprocket shaft 28, mutilation symbol gear 29, hand wheel shaft 30, fixed character 31, travel switch 33 backhaul bullet Huangs 34, fixedly Xiao's 35 compositions such as grade.A ocra font ocr head is with a plurality of angles tooth connection wheel 27, rotates many character keys 26,14 characters of layout on the chain, and any one star connection gear 60 degree angle will change a character as long as rotate wherein, comes the Rapid Combination coding.(Fig. 2)

H ocra font ocr head is the boxlike elasticity backhaul character head of double arrangement, and it is by character 25 (general with the A type), positioning wire 35, travel switch 33 (general), backhaul bullet Huang 34 with the A type,, formation such as slip character box 36.Changing former artificial print cartridge is the chute box, adds backhaul spring and travel switch.Make it to match, it both can single replacing character, also can integral replacing character head.

More than the appearance and size of two kinds of character heads basic identical, can arbitrarily exchange in the character head groove 32, when changing character head or character, but operant activity arm valve 22 revolves movable cantilever 4 and turn 90 degrees and can change.A ocra font ocr head is useful for the circumference steel of big section and prints technology: H ocra font ocr head is useful for the printing technology of light section circumference steel.

This printer is according to technological requirement, utilize compressed air for power, adopt frictional reaction follower fork-like farm tool used in ancient China to guarantee the synchronous location and the printing of character head 9AH and pendulum, utilization quadric chain, hinge connect, slide rail connects to be connected with cylinder etc. and finishes each action request.Adopt the plate chain type structure, star connection gear 27 drives character vessel used to hold grain at the imperial sacrifice 26 and rotates, thereby, change character and encode.The form that adopts monocase and whole character to change first watch satisfies connecting rod pendulum or pneumatic pick and prints, and its printing is clear fast.(print speed is no more than 15 seconds) finishes contraposition accurately, prints return three road main technique.Can satisfy many specifications, requirement is printed in the reproduction of many kinds (square steel, round steel, tetrad square steel and round steel).

Four, the course of work
