The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 1 rolls the two draw rollers mechanism structure scheme drawings of sanction formula folding machine for the utility model;

Fig. 2 is an A-A cutaway view among Fig. 1.

Among the figure: 1 operating surface wallboard, draw rollers on 2,3 pressure rollers, 4 times draw rollers, 5 cut-off knife pressure rollers, 6 upper pressure papers wheel bolster, 7 times pressure roller bolsters, 8 start the face wall plate, 9 first gears, 10 second gears, 11 the 3rd gears, 12 the 4th gears, 13 gear box casinies, 14 servomotors, 15 cylinders, 16 base plates, 17 pressure roller bars, 18 paper, 19 cut-off knife pressure roller bars.

(5) specific embodiment

Referring to Fig. 1, Fig. 2, a kind of two draw rollers mechanisms of sanction formula folding machine of rolling, comprise the draw rollers 2,4 that is installed on the bolster and be installed in pressure roller 3 on the

pressure roller bolster

6,7, bolster and

pressure roller bolster

6,7 are installed in operating surface wallboard 1 and start between the face wall plate 8.Draw rollers and pressure roller bolster respectively comprise two up and down, and upper pressure paper wheel bolster 6 is corresponding to

last draw rollers

2,3, three pressure rollers 3 of three pressure rollers are housed on upper pressure paper wheel bolster 6 paper 18 is pressed in finishes top in the draw rollers 2 and draw the paper function; Following pressure roller bolster 7 is corresponding to draw rollers 4 down, on the pressure roller bolster 7 two pressure rollers 3 and cut-off knife pressure roller 5 are being housed down, cut-off knife pressure roller 5 places in the middle of two pressure rollers 3, two pressure rollers 3 and cut-off knife pressure roller 5 are pressed in down paper 18 and finish the bottom in the draw rollers 4 and draw the paper function, and cut-off knife pressure roller 5 also has the function of cutting.The power of last draw rollers 2 and following draw rollers 4 is driven through gear cluster by servomotor 14.Gear cluster comprises four gears, the 3rd gear 11 connects servomotor 14 output shafts as power gear,

first gear

9 and 10 engagements of second gear,

second gear

10 and 11 engagements of the 3rd gear, the

3rd gear

11 and 12 engagements of the 4th gear, the 3rd gear 11 is identical with second gear, 10 numbers of teeth, and first gear 9 is identical with the 4th gear 12 numbers of teeth, and the ratio of number of teeth of first gear 9, second gear 10, the 3rd gear 11, the 4th gear 12 is 38: 24: 24: 38.First gear 9 connects upward draw rollers 2 bolsters, and the 4th gear 12 connects draw rollers 4 bolsters down, makes that going up draw rollers 2 is drive roll with following draw rollers 4, and five pressure rollers 3 and a cut-off knife pressure roller 5 are follower, drive the latter by the former and rotate.Gear cluster is installed on the gear box casing 13 and is fixed on the lateral surface that starts face wall plate 8, and servomotor 14 is installed on the gear box casing 13.

On pressure roller 3 and the cut-off knife pressure roller 5 cylinder 15 is housed, cylinder 15 is packed on the base plate 16, base plate 16 is installed on the

pressure roller bolster

6,7,3 of pressure rollers connect pressure roller bar 17, pressure roller bar 17 other ends are connected on the base plate 16 and can rotate around

base plate

16,5 of cut-off knife pressure rollers are connected in cut-off knife pressure roller bar 19, and cut-off knife pressure roller bar 19 other ends are connected on the base plate 16 and can rotate around base plate 16, and cylinder 15 piston rods are connected in pressure roller bar 17 and cut-off knife pressure roller bar 19.

It is as follows that the utility model rolls the two draw rollers working process of mechanism of sanction formula folding machine:

The power of servomotor 14 passes to draw rollers 2, draw rollers 4 rotations down by one group of

gear

9,10,11,12, owing to adopt a pair of transition gear transmission, upper and lower draw rollers 2,4 rotation directions are same direction, as anticlockwise direction, the paper that folding mechanism paper bowl comes out is introduced between draw rollers 2 and the pressure roller 3.Pressure roller 3 has certain precompressed compression with respect to last draw rollers 2, this precompressed compression can be adjusted by the bleed pressure of regulating cylinder 15, because friction force effect, last draw rollers 2 drive pressure rollers 3 rotate and spur paper 18 together and are moved into down forward between draw rollers 4 and the pressure roller 3, in like manner spur the set square part that paper 18 enters folding machine.Because the gear pair transmitting ratio is 38: 24: 24: 38, last draw rollers 2 is consistent with the velocity of rotation and the direction of following draw rollers 4.If paper knife work can be two halves with the paper cutting by following draw rollers 4.

When folding machine was worn paper or Installation and Debugging, the cylinder 15 of pressure roller 3 and cut-off knife pressure roller 5 lifted, and made itself and upper and lower draw rollers 2,4 gapped, was convenient to wear the paper action.During work, electricity, gas effect make cylinder 15 drive pressure roller 3 and contact and produce certain pressure with upper and lower draw rollers 2,4, compress paper 18, because the buffer action of cylinder 15, two draw rollers mechanism can adapt to thickness and list, plurality of sheets of paper 18 and produce constant compression force.

When paper cutting apparatus was not worked, cut-off knife pressure roller 5 descended draw rollers 4 to lift relatively, in the time of need cutting a sheet of paper, and cylinder 15 ventilations, the pressure roller of cut-off knife pressure roller 5 is depressed, and the cut-off knife incision is the side of draw rollers 4 median slot down, carries out the action of cutting a sheet of paper.
