Abstract

The utility model provides a rewinder tenslator. The utility model can control paper retreating tensile force according to the requirement of inside tightness and outside looseness in the finished product paper roll, and the utility model is of simple structure, low cost and convenient operation. The utility model is composed of a power transfering device, a driving roller, a radius sensor which is connected to one end of the scroll of the finished product paper, a base paper roll and a tenslator. The utility model is characterized in that a shaft of the base paper roll 7 is connected with a brake which is composed of two couples of gears 8, 10, 11, a magnetic powder brake 9 and a brake velometer 12. A gear 11 is connected with a gear 8 via a gear 10, the brake velometer 12 is arranged on a shaft of the gear 11, and the gear 10 is arranged on a shaft of the magnetic powder brake 9.

Description

The Winder's Tension Control device

The utility model belongs to the papermaking equipment field, is a kind of Winder's Tension Control device specifically.

The present rewinding machine that uses, particularly go up the paper injection rewinding machine, mostly adopt the mechanical friction type drg manually to control the paper power of moving back, though also occurred in recent years controlling the paper power of moving back with electromagnetic power brake, but still be manual actuating, be permanent Tension Control, the high-quality paper roll of tight outer pine is realized by control brake device moment of torsion because move back paper power in can not rolling out.If move back paper power is T, and brake torque is M, and the paper roll radius is r, so, T=M/r, because r is diminishing gradually continuously, if want T to keep constant, M also must be with the reducing and reduce of r, with manually controlling and can't realizing.Some T are according to the curvilinear motion of tight outer pine in the finished roll, and that is extremely difficult, so, move back paper power with manual control, can not roll out the high-quality paper roll.Can and survey warp tension ratio according to theoretical tension force though the patent No. is 90224529.5 rewinding machines, control the paper power of moving back, because of workman in the rewinding working process will pass jockey pulley to paper, paper injection trouble, and cost height, it is also relatively more difficult to transform old rewinding machine.

The purpose of this utility model then is the problem at above-mentioned existence, and a kind of Winder's Tension Control device is provided, and it can move back paper power according to the requirement control of tight outer pine in the finished roll, and simple in structure, cost is low, easy to operate.

The utility model technical solution:

A kind of Winder's Tension Control device, it is by torque transfer, rewinding machine driven roller 4, finished roll 5, be connected in the radius sensor 6 of 5 one ends of finished roll, paper roll 7, tenslator is formed, it is characterized in that being associated with drg on 7 of the paper rolls, drg is made up of two pairs of

gears

8,10,11, electromagnetic power brake 9 and drg velometer 12, gear 11 connects with gear 8 by gear 10, on the axle of gear 11 drg velometer 12 is housed, and gear 10 is contained on the axle of electromagnetic power brake 9.

Fig. 1 is the utility model rewinding machine transmission scheme drawing.

Fig. 2 is the utility model radius sensor construction scheme drawing.

Fig. 3 is the utility model brake structural scheme drawing.

Below in conjunction with accompanying drawing the utility model is further described:

Main motor (comprising velometer) 1 drives rewinding machine driven roller 4 by a pair of

gear

2 and 3, and finished roll 5 rotates finished roll 5 under the effect of driven roller 4.Finished roll 5 drives paper roll 7 by paper web and rotates, and is associated with drg on 7 of the paper rolls, and the moment of torsion M of control brake device is with regard to may command web tension Tk.Drg is by two pairs of

gears

8,10,11, electromagnetic power brake 9 and drg velometer 12 are formed, and gear 8 links with 7 of paper rolls, and a pair of gear 11 connects with gear 8 by gear 10, on the axle of gear 11 drg velometer 12 is housed, gear 10 is contained on the axle of electromagnetic power brake 9.

Electromagnetic power brake 9 adopts CZ type electromagnetic power brake, drg velometer 12 adopts JZT2 type or YCT type electromagnetic adjustable speed motor to make tachogenerator, available other any type of tachogenerator of this device, also available photoelectric interrupter and optical disc, optical disc is associated on the drg main shaft, make it to react its rotating speed, make tach signal with photoelectric interrupter.

Radius sensor 6 is made up of sprocket wheel 13,

gear

14,16 and potential device 15.Sprocket wheel 13 is fixed on the sprocket shaft, rotate with sprocket shaft, sprocket wheel 13 connects with coil paper plunger tip 17 by chain, gear 14 is fixed on the sprocket shaft, and the corner of its corner and sprocket wheel 13 is synchronous, and gear 16 is fixed on the axle of potential device 15, with potential device 15 coaxial rotation, potential device 15 is fixed in lathe bed by support, gear 16 directly and gear 14 nibble order, promptly the rotational angle of potential device 15 has just reflected the radius size of (adjustable height of coil paper plunger tip 17) finished roll 5.

The radius that is set as product paper roll 5 increases to R by O, and the pitch circle of sprocket wheel 13 is d, and the speed ratio of

gear

14,16 is i, and the ultimate angle of potential device 15 is α, then should satisfy relational expression:

α > \frac{R}{πdi} \times 360^{o}

If d is enough big, can potential device 15 directly be connected with sprocket shaft without

gear

14,16.

This device is equally applicable to the occasion that un-derfeed winder and textile printing and dyeing, printing, cutting machine etc. need Tension Control.

Advantage of the present utility model:

Use the utility model, price is lower, and the workman is easy to operate, and the coil paper Functionality, quality and appealing design.
