Abstract
The utility model discloses a scroll unreeling device. A friction pulley (8) is installed on a direct current motor (6), one end of a balance weight (2) is connected with the motor (6) through a fixed pulley (7) mounted at the top of a support (1), the friction pulley (8) is tightly contacted with the excircle of a scroll (9), the friction pulley (8) installed on the direct current motor (6) is used to toggle the excircle of the scroll (9) so as to achieve the scroll unreeling; when the unreeling is so fast that the scroll falls to cover the photoelectric switch, the motor (6) stops; when the falling of the scroll disappears, the photoelectric switch is turned on and the unreeling starts. The unreeling device has simple structure and convenient adjustment of the unreeling speed.
Description
Affiliated technical field
The utility model relates to the paper roll unwinding device in a kind of sheet processing industry.
Background technology
Used paper roll unwinding device generally is that paper roll is fixed on the axle in the sheet processing industry at present, then with the rotation of driven by motor axle, thereby paper roll is unreeled.Make paper reach constant speed or permanent tension force in the process of unreeling to increase constant speed or constant tension device toward contact, structure and the equal more complicated of control for making.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, easy to operate paper roll unwinding device.
In order to achieve the above object, the utility model adopts on a dc motor friction pulley is installed, one end of counterweight links to each other with motor by the fixed pulley that is installed in a top of the trellis, friction pulley closely contacts with the paper roll cylindrical, with the whole pressure of friction pulley on paper roll of suitable adjustable balance weight, paper roll unreels speed thereby the adjusting size of current can change the DC motor rotation speed adjusting.When the speed of unreeling during faster than the paper operating rate, paper is sagging, has blocked optoelectronic switch, cuts off direct current generator and makes its stall, stop to unreel, and after a period of time, sagging contraction, optoelectronic switch is opened, and connects current of electric again, continues to unreel.
The beneficial effects of the utility model are:
1, simple in structure.
2, it is easy to adjust to unreel speed, and a size of current that only needs to regulate direct current generator just can.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further
Fig. 1 is a front view of the present utility model
Fig. 2 is a left view of the present utility model
The specific embodiment
Fig. 2 is a left view of the present utility model, support 1 by four channel-section steels as column, column is fixed with steel plate 4 before and after the middle part, mandrel 3 is housed in the middle of the steel plate 4, at mandrel 3 front ends paper roll 9 is installed, direct current generator 6 is installed on the base plate 5, base plate 5 can slide up and down in four channel-section steels of support 1, friction pulley 8 is fixed on the motor shaft, the cylindrical of friction pulley 8 is close to the paper roll outer ring, the rotating band dynamic friction wheel 8 of direct current generator 6 and paper roll 9 rotations, thereby paper roll is unreeled, and an end of counterweight 2 links to each other with motor 6 by the fixed pulley 7 that is installed in support 1 top, and other end freedom is sagging, the weight of adjusting counterweight 2 can be adjusted the size of frictional force between friction pulley 8 and the paper roll 9, and friction pulley 8 outsides are coated by rubber.The size of current of regulating direct current generator 6 can be regulated its rotating speed, thereby regulate the speed that unreels of paper roll, when the speed that unreels of paper roll during greater than the processed speed of paper, unnecessary paper is sagging, covered optoelectronic switch 10 (among Fig. 1), cut off dc motor power, the motor stall unreels and stops, when sagging paper disappears, optoelectronic switch is opened, and motor rotates again, continues to unreel.
Claims (2)
1. the unwinding device of a paper roll, comprise dc motor, it is characterized in that: dc motor (6) is gone up friction pulley (8) is installed, and an end of counterweight (2) links to each other with motor (6) by the fixed pulley (7) that is installed in support (1) top, and friction pulley (8) closely contacts with paper roll (9) cylindrical.
2. the unwinding device of paper roll according to claim 1, it is characterized in that: the appearance of friction pulley (8) is coated with rubber.
