The specific embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, the present invention is described in more detail.
As shown in Figure 1, wherein, set square adopts the part decomposing to combine to the structure of set square, comprises side air cushion cylinder 11, covers plate 12, nose 14.Described illiteracy plate is arranged on the front of set square, contacts the one side of paper tape.Side air cushion cylinder 11 has two, is arranged on respectively on two sides of set square, with flathead screw, side air cushion cylinder 11 and illiteracy plate 12 is linked together.The surface of described side air cushion cylinder 11 is smooth curved surface, and what assurance paper tape can be level and smooth passes through.The pore 23 that offers air flue 22 in side air cushion cylinder 11 and nose 14 and be communicated with air flue 22.In paper tape high-speed mobile, in air flue 22, pass into pressurized air, compressed air inlet is that air flue entrance 24 is at the connecting portion of nose 14 and set square, pressurized air is in the interior circulation of air flue 23 and go out from pore 23, between paper tape and set square, form air cushion, removed the hard friction of paper tape and set square, prevent from printing the picture and text set-off in printing, guaranteed printing print quality, the real device of realizing coupling high speed web printing folding apparatus.
Optionally, the diameter of pore 23 is 1.5-5mm.
Optionally, the connection mode of described nose 14 and described set square as shown in Figure 4 and Figure 5, nose adapter plate 16 is arranged on the back side of set square, and the fore-end of nose adapter plate 16 extends the drift angle end of set square, nose connecting element 15 next-door neighbour's set square drift angle ends are arranged on the extendible portion of nose adapter plate 16, and nose 14 is arranged on nose connecting element 15.
Position adjusting mechanism, as shown in Fig. 1 and Fig. 3 institute, comprises pivot shaft 3, supporting seat 1, stay bearing plate 2 and adjusts screw 4.Pivot shaft 3 is arranged between both sides wallboard 5, and the two ends of stay bearing plate 2 are separately installed with 1, two supporting seat 1 of supporting seat and are enclosed within on pivot shaft 3, and set square is arranged on stay bearing plate 2.On two supporting seats 1, all install and adjust screw 4, the axially parallel 1 of the axial and described pivot shaft 3 of described adjustment screw 4, described adjustment screw 4 contacts with described body of wall 5 through described supporting seat 1, when the relative supporting seat 1 of adjustment screw 4 turns, turn two simultaneously and adjust screws 4.When supporting seat 1 need to be adjusted left, unscrew the adjustment screw 4 on the left side, tighten the adjustment screw 4 on the right simultaneously, because the adjustment screw 4 on the right contacts with wallboard 5, cannot move right again, therefore force supporting seat 1 along pivot shaft 3 be axially that X axis in Fig. 1 moves left, thereby drive whole set square to move left along X axis.Same, in the time of need to adjusting the position of supporting seat 1 to the right, unscrew the adjustment screw 4 on the right, tighten the adjustment screw 4 on the left side simultaneously and can realize.
Optionally, as shown in Figure 2, described set square and described stay bearing plate 2 fixedly mount by attaching parts 9, attaching parts 9 is connected with stay bearing plate 2 with connecting panel 10 by bolt, connecting panel 10 is arranged on the back side of set square, and attaching parts 9 is a bending attaching parts, makes set square downward-sloping.
As shown in Figure 5, actuating device 6 is with described adjusting screw mandrel 8 by a pair of gear 7 engagements for set square angle-adjusting mechanism, and actuating device 6 driven gears 7 rotate, and gear 7 connects the one end that regulates screw mandrel 8, and gear 7 can drive and regulate screw mandrel 8 to rotate thereupon while rotating.Bearing 21 and fixed mount 20 next-door neighbour's gears 7 are installed, and in the middle of adjusting screw mandrel 8 is enclosed within, due to the restriction of bearing 21 and fixed mount 20, regulate screw mandrel 8 can not move on axial location, can only original position rotate.Regulate the other end of screw mandrel 8 to be threaded with adjusting nut 9, the other end of adjusting nut 9 connects hinge-rod 13, the other end connecting hinge chain rivet 18 of hinge-rod 13, hinge axis 18 is arranged between two mounting blocks 17, two mounting blocks 17 are arranged on the back side of nose adapter plate 16, the i.e. one side relative with nose connecting element 15 attachment faces, or be directly installed on the back side of set square.Regulating screw mandrel 8 rotation processes owing to regulating screw mandrel 8 axially can not move, therefore can force the adjusting nut 19 coordinating with it along regulating moving axially of screw mandrel 8, and then drive the hinge-rod 13 and the hinge axis 18 that are attached thereto to move along adjusting screw mandrel 8, because mounting blocks 17 is arranged on the back side of set square, hinge axis 18 can drive set square to take described X-axis as axis rotation, and causing described set square and vertical direction is the variable angle of Y-axis.Therefore the rotation of adjusting screw mandrel 8 finally can drive the angle α of set square and Y-axis to change, and adjusts the pressure between paper tape and described set square.This device of while can be realized actuating device 6 and automatically control.Can according to technological requirement, to its angle α, adjust in process of production, effectively prevent that at a high speed vertical folding process, paper tape is wrinkling.
As can be seen from above, folding set square device provided by the invention, air flue 22 and pore 23 on side air cushion cylinder 11 and nose 14, have been designed, during work, at its air flue 22, pass into pressurized air, pressurized air is gone out from pore 23 in the interior circulation of air flue 22, between set square side air cushion cylinder 11, nose 14 and paper tape, forms air film, has removed the hard friction of paper tape and set square, prevent from printing the picture and text set-off in printing, guaranteed printing print quality.In order to reach the angle of set square and position, must require the object through row adjustment along with paper breadth size and thickness and typography, under high speed printing speed, paper tape is indulged folding by nose 14, by simple set square position adjusting mechanism and set square angle-adjusting mechanism, according to technological requirement, can prolong X-axis to the position of set square and setting device thereof and move adjustment; According to paper tape situation, adjust the angle α of set square, reach the pressure of adjusting set square and paper tape, keep suitable pressure, guarantee that paper tape is in vertical folding process, not sideslip, do not produce fold and tear, reducing the wastage rate of paper, the real device of realizing coupling high speed web printing folding apparatus.The integral structure of set square adopts combination mechanism, has reduced the accurately machined difficulty of high-volume parts, has saved cost simultaneously.
Those of ordinary skill in the field are to be understood that: the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any modification of making, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
