Satellite gear Z2, Z3 are dynamic gear trains, all the other are fixed shaft gear trains, transmission principle according to the planetary differential train, when sun wheel Z1 rotates, output gear Z4, pinion carrier gear Z5 can rotate by mutual action, make spool gears Z7, spool gears Z9 drive the load first spool 5-R1, the second spool 5-R2 by certain related law running.
As shown in Figure 3, the coupled drive bag is the pinion carrier input structure, comprises input gear Z0, sun wheel Z1, sun wheel Z1 ', satellite gear Z2, satellite gear Z3, output gear Z4, output gear Z4 ', pinion carrier gear Z5, idle pulley Z6, idle pulley Z8, spool gears Z7, spool gears Z9; The output shaft that is socketed on the distribution gear is connected with input gear Z0, pinion carrier gear Z5 up and down in turn, and pinion carrier gear Z5 is in transmission connection mutually with sun wheel Z1, satellite gear Z2, satellite gear Z3, output gear Z4 respectively; Pinion carrier gear Z5 drives pinion carrier rotates the planetary system of being made up of sun wheel Z1, satellite gear Z2, satellite gear Z3, output gear Z4; Satellite gear Z2 and sun wheel Z1 engagement, satellite gear Z3 and the output gear Z4 engagement coaxial with satellite gear Z2, output gear Z4 ' and the idle pulley Z8 engagement coaxial with output gear Z4, idle pulley Z8 meshes with spool gears Z9 again, drives the second spool 5-R2 and rotates; Satellite gear Z2 and sun wheel Z1 engagement, sun wheel Z1 ' and the coaxial socket of sun wheel Z1, sun wheel Z1 ' and idle pulley Z6 engagement, idle pulley Z6 meshes with spool gears Z7 again, drives the first spool 5-R1 and rotates.
Satellite gear Z2, satellite gear Z3 are dynamic gear trains, all the other are fixed shaft gear trains, transmission principle according to the planetary differential train, when pinion carrier gear Z5 rotates, sun wheel Z1, output gear Z4 can rotate by mutual action, make spool gears Z7, spool gears Z9 drive the load first spool 5-R1, the second spool 5-R2 by certain related law running.
Be not limited only to an electrical motor 1 bonded assembly retarder 2 output shafts in the present embodiment by 2 coupled drive bags 4 of distribution gear 3 engagements, can also mesh a plurality of coupled drive bags 4, on each coupled drive bag 4 kinetic moment and speed is delivered on it on two spools 5 of bonded assembly.On each spool 5, distribute a band 6.
As shown in Figure 5, be slitter component bar coiling technique facility location sketch.Connect a band 6 on each spool 5, by separation slewing rollers 7 band 6 is directly sent into spool 5 by each band 6 of circle shear 12 itemizes and carry out tension coiling.
This mechanical transmission method combining that can satisfy the strip coiling actual needs that the present invention proposes.Its strip coiling need be extensive and special.In the band rip cutting, deduct marks, layer grades in the manufacturing line, a band is divided into multi-ribbon, all will roll respectively simultaneously then, and all will can not degree of tightness differ according to identical tension coiling, this application is very extensive.This method can be invented a multireel axle reeler, and with a drive of motor, because the effect of coupled drive bag, each spool can need the running of variable speed ground by load, so both can realize that the isostension of each band batched.
Through theoretical calculation analysis, because the effect of transmission bag, moment can be assigned on each spool by the load size, and the rotating speed of each spool can automatically adjust according to the length difference of volume band, and the characteristics of intelligence coupling are arranged.
In traditional rip cutting, deduct marks, during layer branchs, tie etc. produce because internal stress discharges, difference appears in band length, batches quality in order to guarantee each bar, normally a spool is rolled up one.But this will increase many cover taking-up equipments, is unpractical for the rip cutting unit especially.Tradition way usually is, free kink is set to be stored, lead with withdrawal plate, re-use tensioner and reeler is set up tension force, circle shear 12 is by sending a dolly 11, intermediate equipment kink 10, feeding roller 9, tension force pressing plate 8, through separation slewing rollers 7 band 6 is sent into spool 5 again and carry out tension coiling, see shown in Figure 4.
If adopt multireel axle reeler, only just can play the effect of many cover reel reelers with a set of equipment, only being provided with one in the middle of slitter and reeler separates slewing rollers and gets final product, save kink 10, sent a dolly 11, equipment such as tension force pressing plate 8, feeding roller 9, tension force pressing plate 8 cancellations of tensioner also can be avoided the scratch of strip surface.Make unit contraction in length, compact in design, easy and simple to handle, investment is saved, as shown in Figure 5.For band adjustable pocket bench plane branch, layer branch, tie unit, also be like this.
Equally, because the application of coupled drive bag, for band adjustable pocket bench plane branch, layer branch, tie unit, and the bull of cotton rope coiling, all can realize the flexibility transmission, promptly decide the speed automatically regulating under the tension force.
