Description
Technical field
The utility model relates to film packing material manufacture field, specifically a kind of magnetic braking apparatus being applicable to film transmission deflector roll.
Background technology
At present, in the film product course of processing, need film repeatedly to transmit operation, in the transmitting procedure of film roll, change due to film roll thickness can make the speed that film transmits change, film roll is easily caused to roll up the not high situation of film planeness, existing film transmits deflector roll and is mostly to be directly fixed on film transmission equipment, stable tension force can not be provided to promote the smooth transport of film according to the film that is changed to of film roll thickness, reduce the planeness of film and the work efficiency of film transmission.
Utility model content
The purpose of this utility model overcomes existing film transmission deflector roll to be changed to according to film roll thickness the defect that film provides stable tension force, provide a kind of rational in infrastructure, work efficiency is high, the magnetic braking apparatus being applicable to film transmission deflector roll of Be very effective.
A kind of magnetic braking apparatus being applicable to film transmission deflector roll, comprise deflector roll and magnetic brake, it is characterized in that: described magnetic brake comprises yoke, back-up ring, armature, flange ring, described yoke is provided with knock hole, and coil is provided with in yoke, knock hole can improve the installation firmness of yoke, and then improve the firmness of magnet stopper, be convenient to the rotation of deflector roll, described coil is connected with lead-in wire, described back-up ring is arranged in yoke, back-up ring avoids the leakage field phenomenon of yoke, be conducive to the efficiency improving magnetic brake, described armature is arranged between yoke and flange ring, and by rivet by yoke, armature, flange ring links together, rivet improves armature and yoke, Joint strenght between flange ring, and then improve the capability and performance of magnetic brake, the stability that further raising adapter shaft rotates in magnet stopper, described deflector roll two ends are provided with adapter shaft, and be provided with except electric groove in guide roller surface, except the electrostatic carried in film transmitting procedure can be removed by electric groove in time, be conducive to planeness when improving film roll volume film, described adapter shaft is arranged in flange ring, coil in yoke is by producing magnetic force after lead-in wire energising, magnetic force orders about adapter shaft and rotates, and then drive deflector roll to rotate, deflector roll is enable to provide required tension force for film transmits, promote that the smooth sequential of film transmission runs.
Further, described removes electric groove, and its quantity is 2-6 bar.
Beneficial effect: the utility model is provided with magnetic brake on the adapter shaft at deflector roll two ends, can the rotative speed of control linkage axle by magnetic brake, and then the rotative speed of deflector roll can be controlled, deflector roll is enable to provide required tension force for film transmits, promote the smooth running of film transmission, by guide roller surface except electric groove, the electrostatic produced in film transmitting procedure can be removed in time, be conducive to the planeness that improve film roll.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. deflector roll, 2. yoke, 3. back-up ring, 4. armature, 5. flange ring, 6. knock hole, 7. coil, 8. lead-in wire, 9. rivet, 10. adapter shaft, 11. are except electric groove.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in detail.
As shown in drawings: a kind of magnetic braking apparatus being applicable to film transmission deflector roll, comprise deflector roll 1 and magnetic brake, it is characterized in that: described magnetic brake comprises yoke 2, back-up ring 3, armature 4, flange ring 5, described yoke 2 is provided with knock hole 6, and coil 7 is provided with in yoke 2, knock hole 6 can improve the installation firmness of yoke 2, and then improve the firmness of magnet stopper, be convenient to the rotation of deflector roll 1, described coil 7 is connected with lead-in wire 8, described back-up ring 3 is arranged in yoke 2, back-up ring 3 avoids the leakage field phenomenon of yoke 2, be conducive to the efficiency improving magnetic brake, described armature 4 is arranged between yoke 2 and flange ring 5, and by rivet 9 by yoke 2, armature 4, flange ring 5 links together, rivet 9 improves armature 4 and yoke 2, Joint strenght between flange ring 5, and then improve the capability and performance of magnetic brake, the stability that further raising adapter shaft 10 rotates in magnet stopper, described deflector roll 1 two ends are provided with adapter shaft 10, and be provided with except electric groove 11 on deflector roll 1 surface, described removes electric groove 11, its quantity is 4, except the electrostatic carried in film transmitting procedure can be removed by electric groove 11 in time, be conducive to planeness when improving film roll volume film, described adapter shaft 10 is arranged in flange ring 5, coil 7 in yoke 2 produces magnetic force after being energized by lead-in wire 8, magnetic force orders about adapter shaft 10 and rotates, and then drive deflector roll 1 to rotate, make deflector roll 1 can provide required tension force for film transmission, promote that the smooth sequential of film transmission runs.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art and is realized.
