By adopting technique scheme, in view of produced problem in prior art, cutter assembly is increased in a rear step in sheet movement direction, in time being carried to next step by transfer roller after paper one end is folded, utilize the cooperation of horizontal cutting roller and cylinder, when paper is by the gap between horizontal cutting roller and cylinder, paper can be squeezed on the flexible block on cylinder by the cutting knife of horizontal cutting roller, then paper can shape spaced tiny circular hole in a row in this process, and then paper is passed in next step, because blade defines the tiny circular hole of a row on paper, so time follow-up roller carries out extruding transmission to paper, gas just can discharge from these tiny circular holes, gas of the prior art is there will not be to be disturbed paper by being squeezed, some corners of paper are made to occur the problem of flanging, intervene afterwards mechanism paper is out made to have had very large improvement in folding effect, also improve printing quality effect from another angle, also improve corresponding printing efficiency.
Accompanying drawing explanation
Fig. 1 is the cutter assembly structural representation of the utility model web press sheet folding mechanism embodiment;
Fig. 2 is the overall structure schematic diagram of the utility model web press sheet folding mechanism embodiment;
Fig. 3 is the blade structure schematic diagram of the utility model web press sheet folding mechanism embodiment.
Detailed description of the invention
Referring to figs. 1 through Fig. 3, the utility model web press sheet folding mechanism embodiment is described further.
A kind of web press sheet folding mechanism, comprise live-roller group, described live-roller group includes two transfer rollers 11 arranged in gap, described live-roller group also includes for the cutter assembly of paper perforating, described cutter assembly includes the horizontal cutting roller 1 and cylinder 3 that rotate in opposite directions, the gap passed through for paper is provided with between described horizontal cutting roller 1 and cylinder 3, described horizontal cutting roller 1 is provided with the blade 2 of indentation and the axis of described blade 2 transversely cutting roller 1 is arranged, the surface of described cylinder 3 is fixedly installed flexible block 4, when paper passes through between horizontal cutting roller 1 and cylinder 3, paper and blade 2 are mutually conflicted and described paper is simultaneously inconsistent with flexible block 4.
After paper is by printing unit, paper can take the lead in being delivered to top margin of a page mechanism 9, top margin of a page mechanism 9 is being delivered on set square 10, paper direction is earthward transmitted, so in the utility model, the preferred below that cutter assembly can be positioned in positional structure transfer roller 11, do not limit its concrete arrangement in practice, because when paper folds from set square 10, if now directly carry out the punching work of cutter assembly, corresponding Transfer Quality can be affected, punch so preferably still first utilize transfer roller 11 paper to be carried out stable folding rear recycling cutter assembly.
Described cutter assembly comprises horizontal cutting roller 1 and cylinder 3, described horizontal cutting roller 1 is provided with two cavitys 7, the axial direction of two cavitys 7 transversely cutting roller 1 is arranged, longitudinal tangent plane of described horizontal cutting roller 1 can be seen, the shape of described cavity 7 is preferably right angled triangle, two cavitys 7 according to the center of circle in being oppositely arranged, be provided with mounting blocks 6(mounting blocks 6 in one of them cavity 7 to be mainly used for blade 2 and flexure strip 5 are installed), corresponding balancing weight 8 is provided with in cavity 7 corresponding thereto, two right-angle sides of described cavity 7 inside can be installed easily to mounting blocks 6 and balancing weight 8, facilitate and produce and assembling.
In the cavity 7 installing blade 2 side, setting direction along cavity 7 is provided with some screwed holes, described screwed hole is positioned on unified straight line, described mounting blocks 6 utilizes securing member to be removably fixed in corresponding cavity 7, described blade 2 modes be directly threaded connection are positioned on mounting blocks 6, if blade 2 occurs that wearing and tearing can be convenient for changing.
Described cylinder 3 and horizontal cutting roller 1 rotate in opposite directions, namely horizontal cutting roller 1 rotates clockwise, then 3, cylinder is for rotating counterclockwise, along the rotation direction of described horizontal cutting roller 1, described blade 2 and flexure strip 5 set gradually, described flexure strip 5 is fixed on horizontal cutting roller 1 by securing member, one end of described flexure strip 5 extends towards cylinder 3 side, because the flexible block 4 on cylinder 3 adopts elastomeric material to make, when paper is between blade 2 and flexible block 4 when process, paper can be squeezed on flexible block 4 by blade 2, paper can certain probability and flexible block 4 stick mutually in together with, like this, paper easily with the rotation of cylinder 3 coiling on cylinder 3, so set up flexure strip 5, the Main Function of flexure strip 5 is exactly after blade 2 carries out transverse direction punching for paper, flexure strip 5 is conflicted the scraps of paper, the scraps of paper and cylinder 3 are separated, can pass through between horizontal cutting roller 1 and cylinder 3 smoothly, it should be noted that herein, the punching of paper and the conflict of flexure strip 5 all complete instantaneously, described flexure strip 5 also only needs to lay a finger on for paper paper just can be made to come off, because between paper and flexible block 4 is not paste very tight.
The main operational principle of this web press sheet folding mechanism is exactly when paper is by the gap between horizontal cutting roller 1 and cylinder 3, paper can be squeezed on the flexible block 4 on cylinder 3 by the cutting knife of horizontal cutting roller 1, then paper can shape spaced tiny circular hole in a row in this process, and then paper is passed in next step, the circular hole defining a row tiny on paper due to blade 2 (it should be noted that herein, in order to better expression, circular hole in accompanying drawing is for amplifying process), so time follow-up roller carries out extruding transmission to paper, gas just can discharge from these tiny circular holes, gas of the prior art is there will not be to be disturbed paper by being squeezed, some corners of paper are made to occur the problem of flanging, intervene afterwards mechanism 12 paper is out made to have had very large improvement in folding effect, also improve printing quality effect from another angle, also improve corresponding printing efficiency.
Arrange tiny circular hole in view of this and can bring apparent impact to the whole structure of printing, horizontal cutting roller 1 and cylinder 3 can be controlled and coordinate with the rotating speed of live-roller to control the position that this arranges tiny circular hole, preferably this can be arranged tiny circular hole beats in the position needing the later stage to cut, so also facilitate cutting of later stage, and can not outward appearance be affected.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
