Description
Technical field
This utility model relates to rolling screen door technical field, particularly relates to a kind of modified model exchange door roller.
Background technology
Rolling screen door lifting is driven by door roller, and rolling screen door lifting puts in place or midway stops, and not only door roller motor to shut down, and also to brake door roller, and otherwise due to the weight of rolling screen door self, rolling screen door can down be fallen.
Existing exchange door roller braking control device is mainly made up of brake disc, brake block, brake spring and solenoid (electric magnet), under door roller halted state, the thrust of spring promotes brake block and brake disc to be in close contact and brakes；During door roller work, solenoid energising attracts brake block, makes brake disc separate with brake block, is maintained to door roller and shuts down.Solenoid is general and door roller motor winding parallel, owing to the voltage at solenoid two ends is fixing, therefore, it is no matter solenoid energising moment of being sucked away from brake block, or maintaining brake block and the released state of brake disc, the size of current of solenoid is identical.Actually, before electric magnet is not operating, owing to iron core and the armature of electric magnet exist magnetic gap, the most also there is a certain distance, so the moment of electric magnet action needs bigger electric current, and after electric magnet Guan Bi, unshakable in one's determination and armature tightly combines, and does not has therebetween magnetic gap, forms closed magnetic circuit, magnetic flux increases, and maintains the electric current of electric magnet Guan Bi just can be greatly reduced.It is, solenoid energising is sucked away from the moment of brake block, it is desirable to there is bigger electromagnetic attraction, namely requires that solenoid has bigger electric current, and maintenance is sucked away from state and has only to less electric current.Therefore, the solenoid of existing Parallel Design wastes a part of electric energy, also results in solenoid excessive heating；Secondly, the control circuit of existing exchange door roller is typically provided 3-4 relay, its objective is to make motor can rotate forward, invert, and makes interlock between relay, it is ensured that relay will not misoperation, so make circuit structure become complexity, expense is the highest.
