Abstract
The invention discloses an unwinding tension control device of a wound film capacitor. The unwinding tension control device comprises a rack, an unwinding shaft, a fixed ring and a movable ring. The fixed ring is fixed to the rack, the movable ring is arranged on one side of the fixed ring and can rotate synchronously or asynchronously along with the unwinding shaft, a friction ring is arranged between the movable ring and the fixed ring, a spring is arranged on one side of the movable ring and connected with an adjusting nut, the adjusting nut is installed at one end of the unwinding shaft, and the unwinding shaft is provided with threads matched with the adjusting nut. According to the unwinding tension control device of the wound film capacitor, torque is transmitted to the unwinding shaft by generating friction force so as to control unwinding tension, namely, the torque is transmitted to the unwinding shaft through friction between the fixed ring and the movable ring so as to control the unwinding tension; the movable ring and the unwinding shaft can rotate asynchronously, so that it is guaranteed that the torque transmitted to the unwinding shaft is constant, and the tension control effect is good. The unwinding tension control device is simple in structure and low in cost.
Description
Technical field
The present invention relates to film capacitor production equipment technical field, specifically belong to a kind of unreeling tension control device of coiled film electric capacity.
Background technology
In the manufacture process of film capacitor, fuse winding is a very crucial production process.This operation roll up be placed on unreeling shaft with light film film metallized film film volume or aluminium pool, and the film that film is rolled up is through guide roller around on core axle, and namely core axle is wound into thin-film capacitor core after rotating a fixing turn.In winding process, unwinding tension controls bad meeting and causes face loose, directly affects film capacitor electrical property.Existing unwinding tension control method has: 1. automated manner, utilizes floating roller or follow the tracks of arm to detect tension force, and closed-loop control servo system realizes winding tension and regulates, though effect is good, and complex structure, cost is high; 2. Non-follow control, utilizes pneumatic braking device or magnetic powder brake unreeling arm generation moment of torsion, thus the tension force needed for obtaining, though save certain equipment cost, tension force control effects is poor.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, provide the unreeling tension control device of high a kind of coiled film electric capacity, tension force control effects is good, and structure is simple, and cost is low.
The technical solution used in the present invention is as follows:
A kind of unreeling tension control device of coiled film electric capacity, comprise frame, unreeling shaft, retainer ring and loose collar, described retainer ring is fixed in frame, retainer ring side is provided with loose collar, and loose collar along with unreeling shaft is synchronous or asynchronous rotation, can be provided with drag ring between described loose collar and retainer ring, loose collar side is provided with spring, spring connects adjusting nut, and described adjusting nut is arranged on one end of unreeling shaft, and unreeling shaft is provided with the screw thread matched with adjusting nut.
Described drag ring material is wool felt material.
When the present invention uses, the film of coiled film electric capacity volume is inserted in unreeling shaft and locks, the film rolled up by film causes the core of thin-film capacitor to be spooled, rotating adjusting nut makes spring contraction, compress loose collar and drag ring makes there is certain frictional force between itself and retainer ring, start coiler device, make the core of thin-film capacitor to be spooled rotarily drive unreeling shaft to rotate, loose collar and drag ring rotate with unreeling shaft, itself and retainer ring produce certain moment of torsion and pass to unreeling shaft, when membrane tension is moderate, loose collar and drag ring and unreeling shaft synchronous rotary, when membrane tension is excessive, loose collar and drag ring and unreeling shaft asynchronous rotation, and then reach the object of unwinding tension control.
Compared with the prior art, beneficial effect of the present invention is as follows:
The unreeling tension control device of coiled film electric capacity of the present invention controls unwinding tension by producing frictional resistance to unreeling shaft transmitting torque, namely the friction between retainer ring and loose collar is utilized to produce moment of torsion to unreeling shaft, reach the object that unwinding tension controls, loose collar and unreeling shaft can asynchronous rotations, ensure to pass to the constant moment of torsion of unreeling shaft, tension force control effects is good, and structure is simple, and cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
