Description
Technical field
What the present invention relates to is a kind of three-knife trimming, in particular the cutter frame regulating mechanism of three-knife trimming.
Background technology
Because a large amount of printings of books, after a large amount of books are printed, the uniformity of its length and width, all adopt three-knife trimming, this three-knife trimming, books are laterally placed on the operating platform, will cut the length of books, cut the width of books with preceding cutter with two side tools of three-knife trimming.And at present, three-knife trimming is more on the market, a kind of three-knife trimming the most commonly used is that two knife rests are installed on a main shaft, side tool is installed on knife rest, cutter before install in operating desk the place ahead of ripper in the above, when main shaft moved down, two side tools were just cut out to books, will be cut into length and unify books, and the ripper of this structure, its knife rest is fixed on the main shaft by the cover reed, is provided with bolt on the reed arm of cover reed, and threaded push rod is set on support, this push rod contacts with knife rest, on main shaft, also be provided with scale, regulate the distance between two side tools, when just regulating the cutoff length of books needs, to unclamp the bolt on the reed arm earlier, make the cover reed on main shaft, to move, again the handle that is connected with push rod of turn, just follow rest, see the distance that the scale upper tool post moves again, could regulate the cutoff length of books, regulate the bolt that will screw after finishing on the reed arm, the reed arm is fastened on the main shaft.And this adjustment structure, its accuracy is very poor, and the cover reed is moved, and is like this, after side tool cuts, bigger with needed error in length.And this employing bolt comes the mode of adapter sleeve reed, and reliability is very low, because when side tool cut books, impulsive force was bigger, thereby just might make the cover reed on main shaft, rotate, so just cause side tool to cut halfway situation and take place, serious cause scrapping of whole book.
Summary of the invention
In view of the deficiency that background technology exists, the technical problem to be solved in the present invention provides a kind of cutter frame regulating mechanism of regulating accurate and stable three-knife trimming.
For this reason, the present invention realizes by the following technical solutions: a kind of cutter frame regulating mechanism of three-knife trimming, comprise main shaft, knife rest and cover reed, described cover reed has left side cover reed and right cover reed, the cover reed is enclosed within on the main shaft about described, the cover reed is connected with described knife rest respectively about described, it is characterized in that being bolted with left screw rod on the cover reed of a described left side, be bolted with right screw rod on the described right cover reed, described left screw rod is connected with right screw rod, and left screw rod is opposite with right screw spiral direction, and described left screw rod or right screw rod and reducing motor are in transmission connection, and described reducing motor is electrically connected with Programmable Logic Controller.
Be equipped with cylinder on the following reed arm of cover reed about described, reed arm connection on the push rod of described cylinder and the corresponding cover reed.
Be connected with connecting rod on the last reed arm of described cover reed, described rod hinge connection fork, the push rod of described fork and described cylinder is hinged.
Described left screw rod is connected by the screw mandrel adapter sleeve with right screw rod.
One end of described left screw rod or right screw rod is equipped with encoder, and described encoder is electrically connected with described Programmable Logic Controller, and described encoder, reducing motor and Programmable Logic Controller form closed-loop control mechanism.
Among the present invention, adopt Programmable Logic Controller to set the distance numeral that knife rest moves, just driving left and right sides screw rod by reducing motor rotates, because the hand of spiral of left and right sides screw rod is opposite, so, the cover reed relatively moves about just can making, reach the purpose of regulating distance between the knife rest of the left and right sides, this regulative mode, accurate and stable, solved the problem that exists in the background technology preferably; And the setting of cover reed casing top half can strut the cover reed or fix easily, the unfailing performance height.

The specific embodiment
With reference to accompanying drawing, the cutter frame regulating mechanism of this three-knife trimming, comprise main shaft 1, knife rest 3,3 ' and the cover reed, described knife rest 3,3 ' on be installed with cut-off knife 5 respectively, 5 ', described cover reed have left side cover reed 2 and right cover reed 2 ', cover reed 2 about described, 2 ' be enclosed within on the main shaft 1, cover reed 2 about described, 2, ' respectively with described knife rest 3,3 ' fixedly connected, be bolted with left screw rod 4 on the cover reed 2 of a described left side, described right cover reed 2 ' on be bolted with right screw rod 4 ', described left screw rod 4 and right screw rod 4 ' be connected by screw mandrel adapter sleeve 6, and left screw rod 4 is opposite with right screw rod 4 ' hand of spiral, described right screw rod 4 ' on be fixed with driven gear 8, driving gear 9 is installed in the rotating shaft on the reducing motor 7, described driving gear 9 and driven gear 8 engagements make reducing motor 7 and right screw rod 4 ' formation be in transmission connection, and described reducing motor 7 is electrically connected with the Programmable Logic Controller (not shown); About described the cover reed 2,2 ' following reed arm 16 chains be connected to installing rack 15, cylinder 14 is installed on installing rack 15, be connected with connecting rod 11 on the last reed arm 10 of described cover reed, described connecting rod 11 hinged forks 12, described fork 12 is hinged with the push rod 13 of described cylinder 14, the push rod 13 of described cylinder 14 and corresponding last reed arm 10 connections; One end of described left screw rod 4 is equipped with encoder 17, and this encoder 17 is electrically connected with Programmable Logic Controller, and described encoder, reducing motor and Programmable Logic Controller form a closed-loop control system.
Among the present invention, in the time need mediating to the distance between the cut-off knife, as long as the man-machine dialog interface of the numeral that will need to regulate input Programmable Logic Controller, Programmable Logic Controller is just controlled air pump work, the air pump gas transmission is to cylinder 14, and the push rod 13 of cylinder 14 is risen, the rising of the push rod 13 of cylinder 14 drives fork 12, fork 12 drivening rods 11, and make connecting rod 11 pullings overlap the last reed arm 10 of reeds, this cover reed that is enclosed within on the main shaft 1 just unclamps, make the cover reed can move at main shaft 1, then, Programmable Logic Controller just instructs reducing motor 7 to work, driving gear 9 on the reducing motor 7 drives driven gear 8 and rotates, thereby drive right screw rod 4 ', driving left screw rod 4 simultaneously rotates, because left and right sides screw rod 4,4 ' the hand of spiral opposite, and left and right sides screw rod 4,4 ' be screwed onto respectively about the cover reed 2,2 ' on, so left and right sides screw rod 4,4 ' when rotating, just cover reed 2 about can passing through, 2 ' make its corresponding knife rest 3,3 ' relative to or move in opposite directions, when left side screw rod 4 rotates, the encoder 17 that is installed in left screw rod 4 one ends just sends pulse signal to Programmable Logic Controller, cover reed 2 about Programmable Logic Controller calculates according to the umber of pulse that obtains, 2 ' in other words knife rests 3,3 ' relative to or the distance that moves in opposite directions, when about the cover reed 2,2 ' or knife rest 3,3 ' relative to or the distance that moves in opposite directions reach input apart from the time, Programmable Logic Controller just instructs reducing motor 7 to quit work, so, just, can be to knife rest 3,3 ' between distance accurately regulate, and stability is good.
