Abstract

The utility model belongs to a part of a paper roll splitting machine, and relates to a tension controlling device different from a prime magnetic powder clutch tension control and electronic tension control in structure. The utility model adopts a structure that the difference of number of teeth of a paper tape rewinding drive gear is one. Therefore, the aim that the linear velocity of the paper tape is a constant value as the paper tape rewinding diameter becoming large is realized, and the tension borne by the paper tape in a paper tape rewinding process is a constant value. Consequently, a paper roll is difficult to break in the rewinding process of splitting a paper roll into strips, and the utility model is also capable of rewinding a paper disk with a large diameter. The utility model has the advantages of simple structure, capable of splitting somewhat narrow paper tape, and good service performance.

Description

Tenslator in a kind of novel paper tape after-combustion

The utility model relates to a kind of tenslator that is used for the after-combustion of paper roll cutting machine tape loading.Structurally entirely different with tenslator in the past.

Tenslator in the paper roll cutting machine paper tape after-combustion at present is electronic tensile control and adopts magnetic-powder clutch to control the moment of torsion that changes the after-combustion axle with diameter variation in the paper tape after-combustion.But often the tension force that paper tape bore changes, and is easily broken in the paper tape after-combustion process.Thereby just limited the width of cutting paper tape can not be narrower, simultaneously present electronic tensile control and magnetic-powder clutch are structurally all complicated.

The purpose of this utility model is to provide that tension force and linear velocity are the tenslator of steady state value in a kind of paper tape after-combustion.Make paper roll cut in the paper tape after-combustion of back not broken belt, and can cut narrower paper tape.

The utility model purpose is achieved in that the paper tape after after-combustion is cut on the take-up roll, and the fixing pressure roller in tooth bar upper end compresses paper tape on the take-up roll and two imput shaft, and the tooth bar lower end is connected with cylinder.The tooth bar both sides are equipped with center bearing pilot bearing.The two flower wheel number of teeth differences of installing respectively on two imput shaft be 1 and with same driving wheel engagement.One imput shaft axle head is equipped with adjusting hand wheel, between handwheel and the friction lining is to adjust spring.

Owing to adopt the said structure scheme, make tension force and linear velocity constant in the paper tape rewinding after cutting, be difficult for broken belt when cutting narrower width paper tape, thereby can the large diameter paper disc of after-combustion.This is simple in structure, and in-use performance is good.

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is the utility model tenslator lateral plan.

Fig. 2 is the utility model tenslator imput shaft cutaway view.

1. tooth bars, 2. driving wheels, 3. flower wheels, 4. imput shaft, 5. pressure rollers, 6. paper tapes, 7. take-up rolls, 8. flower wheels, 9. imput shaft, 10. sprocket wheels, 11. centers bearing pilot bearing, 12. cylinders, 13. handwheels 14. are adjusted spring 15. friction linings 16. friction linings among the figure.

In the drawings, take-up roll (7) is gone up after-combustion paper tape (6).After-combustion paper tape (6) and two imput shaft (4) after the fixing pressure roller (5) in guiding tooth bar (1) upper end will be cut tightly, (9) compress.Tooth bar (1) lower end is connected with cylinder (12), and with the diameter increase of the after-combustion paper tape (6) on the take-up roll (7), tooth bar (1) is along center bearing pilot bearing (11) vertical shifting.This hour rack (1) upper end pressure roller (5) compresses take-up roll (7) all the time and goes up after-combustion paper tape (6), makes it to lean on all the time and imput shaft (4), and (9) rub and rewinding.Two imput shaft (4) are equipped with two transmission gears (3) respectively on (9), (8) its number of teeth difference is 1, thereby two gears (3), and (8) rotating speed is different down with same driving wheel (2) engagement, and rewinding paper tape (6) can be tightened up.The paper tape linear velocity is constant in the rewinding process.Along with the increase of the diameter of paper roll (6), imput shaft (4), (9) also are constant with the friction force size of paper roll (6).The tension force that paper tape bore is constant.Imput shaft (4), (9) are to utilize the handwheel (13) that is contained on the imput shaft (9) to adjust spring (14) with pressing friction sheet (15) with the friction force of paper roll (6), realize (16).

Claims

1. tenslator in the novel paper tape after-combustion, paper tape (6) after the last after-combustion of take-up roll (7) is cut, it is characterized in that: the pressure roller (5) that tooth bar (1) upper end is fixed is with paper tape (6) on the take-up roll (7) and imput shaft (4), (9) compress, tooth bar (1) lower end is connected with cylinder (12), in tooth bar (1) both sides center bearing pilot bearing (11) is installed, two imput shaft (4), driven gear (3) is installed respectively (9), and it is 1, two gear (3) that (8) its number of teeth differs, (8) with same driving wheel (2) engagement, imput shaft (9) axle head is equipped with handwheel (13), and handwheel (13) and friction lining (15) are to adjust spring (14) between (16).
