Abstract
The utility model discloses an electromagnetism tension control unwinding device, including unreeling the main shaft, it has connected gradually brake disc, supporting seat to unreel main shaft one side), braking sprocket, clutch and motor, the braking sprocket is connected with the magnetic powder brake sprocket through the chain, magnetic powder brake sprocket coaxial coupling has magnetic powder brake, the brake disc is connected with brake equipment. Keep the tension of steel band steady through magnetic powder brake, also the steel band scarifying can not appear even meet the equipment scram, prevent that the steel band surface from wiping the flower.
Description
Technical field
The utility model relates to a kind of electromagnetism tension force and controls unwinding device.
Background technology
During cold-rolling steel is produced, the first step is exactly that steel band unreels, and the moment that unreels that steel band unreels needs charging tray stable ensures that steel band has certain tensile force, and can brake in time and prevent steel band from getting loose.It is that constant speed unreels that the unwinding device of current use belongs to, and relies on the rotating speed controlling motor to control to unreel speed, then relies on brake facing on main shaft to carry out braking and stop unreeling in case of exceptional circumstances, tension force controls poor, easily occur that steel band loosens, cause steel strip surface to wipe flower, affect product design.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of electromagnetism tension force to control unwinding device, controls tension force in real time, prevent scarifying by electromagnetic power brake.
The utility model solves the technical scheme that its technical matters adopts:
A kind of electromagnetism tension force controls unwinding device, include and unreel main shaft, the described main shaft side that unreels is connected with brake disc, supporting seat in turn), braking sprocket wheel, power-transfer clutch and motor, described braking sprocket wheel is connected with electromagnetic power brake sprocket wheel by chain, described electromagnetic power brake sprocket coaxiality is connected with electromagnetic power brake, and described brake disc is connected with brake gear.
As the improvement of technique scheme, described braking sprocket wheel is identical with the number of teeth of electromagnetic power brake sprocket wheel.
As the further improvement of technique scheme, the axle center of described electromagnetic power brake is arranged on sustained height with the axis unreeling main shaft.
Further, described braking sprocket wheel both sides respectively arrange a supporting seat, and two described supporting seats are as the support of the rotating shaft of braking sprocket wheel.
The beneficial effects of the utility model are: by unreeling the electromagnetic power brake that main shaft connects; the unwinding tension of real-time control steel band; electromagnetic power brake fast response time; output tension force is steady; steel band scarifying can be prevented and occur that flower is wiped on surface; improve the quality of products, production procedure is more smooth and easy, the power generating ratio time.Electromagnetic power brake volume is little in addition, from heavy and light, easy for installation, and long service life is easy to maintenance, is convenient to transform existing unwinding device.The utility model is simple and practical, implements simple, highly efficient durable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is front view of the present utility model;
Fig. 2 is upward view of the present utility model.
Detailed description of the invention
With reference to Fig. 1 ~ Fig. 2, a kind of electromagnetism tension force controls unwinding device, include and unreel main shaft 1, described main shaft 1 side that unreels is connected with brake disc 2, supporting seat 3, braking sprocket wheel 4, power-transfer clutch 5 and motor 6 in turn, described braking sprocket wheel 4 is connected with electromagnetic power brake sprocket wheel 7 by chain, described electromagnetic power brake sprocket wheel 7 is coaxially connected with electromagnetic power brake 8, and described brake disc 2 is connected with brake gear 9.Keep the tension force of steel band steady by electromagnetic power brake 8, stop also there will not be steel band scarifying even if chance equipment is anxious, prevent steel strip surface from wiping flower; And electromagnetic power brake 8 volume is little, from heavy and light, easy for installation, be convenient to the transformation of existing unwinding device, be suitable for promoting on a large scale.
In the present embodiment, preferably, described braking sprocket wheel 4 is identical with the number of teeth of electromagnetic power brake sprocket wheel 7.The identical number of teeth ensures that synchronism is good, and brake response speed is faster.
In the present embodiment, preferably, the axle center of described electromagnetic power brake 8 is arranged on sustained height with the axis unreeling main shaft 1.
In the present embodiment, preferably, described braking sprocket wheel 4 both sides respectively arrange the support of a supporting seat 3, two described supporting seats 3 as the rotating shaft of braking sprocket wheel 4.Adopt said structure, former and later two supporting seats 3 ensure braking sprocket wheel 4 stress balance, stable.
The above, just better embodiment of the present utility model, but the utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, all should fall within protection domain of the present utility model.
