Abstract
The utility model discloses a constant tension pay-off rack which comprises a bottom plate, a stand column arranged on the bottom plate, and a variable frequency motor system. A driving wheel and a driven wheel are arranged on the stand column. The variable frequency motor system drives the driven wheel to rotate through the driving wheel. The driven wheel is fixed on a one-way bearing. One side, close to the stand column, of the one-way bearing is provided with a friction wheel. A brake device is arranged on the circumference where the friction wheel is located in a matched mode and fixed on the stand column. The one-way bearing is movably connected with a supporting shaft at one side of the stand column. As a further improvement, a pressure adjusting wheel is arranged on the brake device. The constant tension pay-off rack can achieve reversal rewinding, and enables a wire to maintain the tension required by winding of coils so as to ensure compactness of the wound coils.
Description
Technical field
The utility model relates to the electrical circuitry equipment manufacturing, relates in particular to a kind of supporting unwrapping wire equipment of coil winding machine.
Background technology
Coil winding machine is the important production equipment of electrical circuitry equipment industry, indispensable equipment in the manufacturing of the power products such as transformer, instrument transformer, inductor.The development of social productive forces is more and more higher to the requirement of coil winding.Determined the service behaviour of power product in the quality of the coiling of coil.And in coil winding, pay off rack is an important corollary equipment.
There is the problem of the following aspects in existing pay off rack:
(1) function singleness can only realize simple tension force to wire rod, in case line falling or coil winding machine revolution, wire rod is just loose; (2) can't realize reclaiming in real time wire rod, need to coordinate take-up more than 2 people as reclaiming, cost of labor is high; (3) coil of coiling is not tight, and quality is unstable.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of permanent tension pay-off creel, and this pay off rack structure can realize reclaiming in real time wire rod, and permanent tension force is provided in the coil winding process, and the mass of coil that closely causes of preventing from winding the line is unstable.
For solving the problems of the technologies described above, permanent tension pay-off creel of the present utility model comprises base plate, is arranged on column and variable-frequency motor system on described base plate; Column is provided with driving wheel, driven pulley, and the variable-frequency motor system drives driven pulley by driving wheel and rotates; Driven pulley is fixed on unilateral bearing, is provided with friction pulley near a side of column on unilateral bearing, and friction pulley mate on the circumference at its place and is provided with brake gear, and the car device that brakes is fixed on column; Unilateral bearing is flexibly connected in column one side and bolster;
As to further improvement of the utility model, be provided with the pressure regulating wheel on brake gear.
Permanent tension pay-off creel of the present utility model can realize by unilateral bearing the take-up of reversing owing to being provided with unilateral bearing; Owing to being provided with brake gear with the driven pulley coupling, can exert pressure to friction pulley by brake gear in the process of forward unwrapping wire, produce braking moment, make wire keep the needed tension force of coiling, tight with the coil that guarantees coiling.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
In conjunction with Fig. 1 as can be known, permanent tension pay-off creel of the present utility model comprises base plate 1, is arranged on column 7 and variable-frequency motor system 3 on described base plate 1; Column 7 is provided with driving wheel 2, driven pulley 4, and variable-frequency motor system 3 drives driven pulleys 4 by driving wheel 2 and rotates; Driven pulley 4 is fixed on unilateral bearing 5, is provided with friction pulley 6 near a side of column 7 on unilateral bearing 5, and friction pulley 6 mates on the circumference at its place and is provided with brake gear 9, and brake gear 9 is fixed on column 7; Unilateral bearing 5 is flexibly connected in column 7 one sides and bolster 8; Be provided with the pressure regulating wheel on brake gear 9.
The specific works state description:
This pay off rack coil is fixed on bolster 8 and the rotation of rotating simultaneously with it:
During forward, bolster 8 drives unilateral bearing 5 rotations that are embedded in friction pulley 6, unilateral bearing 5 drives friction pulley 6 rotations, and at this moment, 9 pairs of friction pulleys 6 of brake gear are exerted pressure, produce thus the anti-restrained force to bolster 8, thereby drum is produced braking moment, and wire rod is tensioning due to braking moment, if braking moment that need to be larger can be by regulating the handwheel on brake gear 9, frictional disk is applied larger pressure compacting friction pulley 6, thereby obtain larger braking moment.
During counter-rotating, due to the unilateral bearing 5 in friction pulley 6, bolster 8 can rotate, and friction pulley 6 does not turn, thereby breaks away from braking moment, and this moment, variable-frequency motor system 3 was by driving wheel 2 rotations, drive driven pulley 4, driven pulley 4 drives bolster 8 reverse rotations, can realize the function of timely take-up.
Permanent tension pay-off creel of the present utility model can also make wire keep the needed tension force of coiling when can realize reversing take-up, tight with the coil that guarantees coiling.
