According to the utility model, when the die cutting drum and the die cutting blade work, the trace cutting line performs micro-circumferential displacement each circle, the tangential point position can be changed to enable the transverse cutting roll to be worn evenly, after the die cutting precision is reduced by the abrasion of the die cutting drum, the velocity compensation is performed for the die cutting drum to enable the die cutting drum to keep the synchronous linear velocity with the main drive gear, and the die cutting precision is kept, thereby greatly improving the service life of the die cutting drum and holding the working efficiency of the high precision die cutter.
Description
Technical field
The utility model relates to a kind of gear drive of packed in cases machinery, specifically is meant a kind of planet gear differential mechanism.
Background technology
Traditional circular pressing and cutting mechanism as shown in Figure 2, it adopts cross cutting tube 51, lower die cut tube 52 on a pair of cross cutting cylinder, load onto die cutting plate 2 and die-cutting rubber mat 4 compositions respectively, and by gear 6, gear 7 transmissions, wherein lower die cut tube 52 is equipped with band cross cutting blade 1 and die cutting plate 2, last cross cutting tube 51 is equipped with die-cutting rubber mat 4, and during cardboard 3 process lower die cut cylinders 52, cross cutting cylinder 52 is finished the cross cutting operation to cardboard 3.Because wear and tear after die-cutting rubber mat 4 uses a period of time, die-cutting rubber mat 4 working diameters diminish, cross cutting cylinder 5 linear differential mutation increases up and down, and progressively reduce mould-cutting precision, and cause die-cutting rubber mat 4 to be scrapped very soon, die-cutting rubber mat is short 4 service lifes, changes frequent.
At present advanced in the world die cutting technique is to install sliding bearing (balanced device) between last cross cutting tube 51 and die-cutting rubber mat 4 additional, makes die-cutting rubber mat 4 and last cross cutting roll 5 and can be free to slide and carry out velocity compensation, can't promote but technology is with high costs.
The utility model content
The purpose of this utility model is to provide a kind of motion mode that adopts planetary gears and main transmission stack, keep and main transmission speed together with the linear velocity after keeping cross cutting plastic roll pad because of wearing and tearing, improve the service life of die-cutting rubber mat cylinder, keep the service precision of die-cutting machine.
To achieve these goals, technical solution of the present utility model is:
A kind of planet gear differential mechanism, roll main drive gear and planetary gears is formed by cross cutting, additional planetary gears on main drive gear, described planetary gears includes: activity centre wheel, fixed center wheel, planetary gear, tie-rod form compound motion.
Former cross cutting roller drive gear increases (or minimizing) one to three tooth, and travelling gear angular speed changes, and the speed of the planetary gears by the few tooth difference of one to three tooth can superpose and carry out velocity compensation again.
The compound transmission of main drive gear and planetary gears transmission stack can make die-cutting rubber pad roller speed and cross cutting rod linear velocity synchronous.
After adopting such scheme, because employing said structure of the present utility model, it has following advantage:
Cut-crease lines was done small circumferential displacement weekly when 1, cross cutting cylinder 5 was with 1 work of cross cutting blade, changed the position, point of contact and made crosscut roll uniform wear;
2, after 5 wearing and tearing of cross cutting cylinder reduce mould-cutting precision, cross cutting cylinder 5 is carried out velocity compensation, make it to keep synchronous, keep mill to cut precision, roll service life, keep high accuracy die-cutting machine operating efficiency thereby greatly improve cross cutting with main drive gear 7 linear velocities.
The utility model is described in further detail below in conjunction with drawings and embodiments:
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the prior art structural representation.
The figure number explanation:
1 cross cutting blade, 2 templates, 3 corrugated boards
4 cross cutting plastic roll pads, 5 cross cuttings roll 6 lower die cut hobbing machines
9 fixed centers wheel is taken turns in cross cutting hobbing machine 8 activity centres on 7
10 planetary gears, 11 tie-rods, 10 ' planetary gears
The specific embodiment
A kind of planet gear differential mechanism, roll main drive gear 7 and planetary gears 10 ' is formed by cross cutting, cooperate shown in Figure 1, it is on the existing structure basis of (as shown in Figure 2), additional active centre wheel 8 on main drive gear 7, fixed center wheel 9, planetary gear 10, tie-rod 11, constitute planetary gears, form compound motion, former cross cutting cylinder 5 travelling gears are increased (or minimizing) one to three tooth, travelling gear angular speed changes, take turns 8 by the planetary gear activity centre of the few tooth difference of one to three tooth again, fixed center wheel 9, planetary gear 10, velocity compensation is carried out in the speed stack of tie-rod 11 transmissions, make the linea angulata speed of cross cutting cylinder 5 approach cross cutting cylinder 5 linear velocities of former transmission mechanism, thereby reach the purpose of cross cutting rubber roll speed difference compensation.Specifically look as follows:
As, former cross cutting diameter of cylinder is φ 440, the modulus M=5 of main drive gear 7, tooth number Z=88, change differential attachment into after, main drive gear 7 changes tooth number Z=86 into, modulus M=5, activity centre wheel 8, fixed center wheel 9, planetary gear 10, tie-rod 11 are planet circular system, modulus M=3, and wherein fixed center is taken turns 9 tooth number Z=84; 8 tooth number Z=86 are taken turns in the activity centre.
When cross cutting cylinder 5 does not wear and tear, tie-rod 11 unpowered inputs (fixing), the utility model is a fixed shaft gear train, gearratio is I1=1.00054.
The small speed difference of the utility model is approached former mechanism angular speed, and purpose is modulus of conversion cutting knife cut-crease lines position, makes die-cutting rubber mat 4 uniform wears.
After die-cutting rubber mat 4 wearing and tearing, diameter diminishes, and then gear is imported power, and the utility model produces compound motion, carries out the speed stack.The planetary mechanism gearratio is I2=-0.024.Cross cutting rolling curve speed was identical about tie-rod 11 inputs one suitable power can reach, and guaranteed mould-cutting precision, improved the die-cutting rubber mat life-span.
Its transmission principle of above-mentioned the utility model is finished by main drive gear 7 and planetary gears 10 ' stack.Be characterized in: cross cutting cylinder 5 and main drive gear 7 stack planetary gears 10 ', planetary gears 10 ' approaches the main transmission linear velocity with a small speed official post cross cutting rolling curve speed.So purpose is to roll cut channel position with die-cutting rule work in order to change cross cutting.After 5 wearing and tearing of cross cutting cylinder, linear velocity changes, and planetary gears 10 ' additional auxiliary power is superimposed upon on the main drive gear 7, makes the die cutting roller linear velocity keep synchronous with the main transmission linear velocity.
Said structure of the present utility model has following advantage:
Cut-crease lines was done small circumferential displacement weekly when 1, cross cutting cylinder 5 was with 1 work of cross cutting blade, changed the position, point of contact and made crosscut roll uniform wear;
2, after 5 wearing and tearing of cross cutting cylinder reduce mould-cutting precision, cross cutting cylinder 5 is carried out velocity compensation, make it to keep synchronous, keep mill to cut precision, roll service life, keep high accuracy die-cutting machine operating efficiency thereby greatly improve cross cutting with main drive gear 7 linear velocities.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique under the situation that does not break away from spirit and scope of the present utility model, can also be made various conversion or variation.Therefore, all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
