Description
Technical field
This utility model relates to rolling screen door technical field, particularly relates to a kind of 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 stop
Operating, also to brake to 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 by brake disc, brake block, brake spring and solenoid (electricity
Magnet) composition, under door roller halted state, the thrust of spring promote brake block and brake disc to be in close contact and brake；Volume
During door machine work, solenoid energising attracts brake block, makes brake disc separate with brake block, is maintained to door roller and stops fortune
Turn.Solenoid is general and door roller motor winding parallel, owing to the voltage at solenoid two ends is fixing, therefore, no matter
It is that solenoid energising is sucked away from moment of brake block, or maintains brake block and the released state of brake disc, the electricity of solenoid
Stream size is identical.It practice, before electric magnet is not operating, owing to iron core and the armature of electric magnet exist magnetic gap, therebetween
Also having a certain distance, so the moment of electric magnet action needs bigger electric current, and after electric magnet Guan Bi, iron core and armature are tight
Tight knot is closed, and does not has therebetween magnetic gap, forms closed magnetic circuit, and magnetic flux increases, and the electric current maintaining electric magnet Guan Bi just can be significantly
Reduce.It is, solenoid energising is sucked away from the moment of brake block, it is desirable to have bigger electromagnetic attraction, namely require electricity
Magnetic coil 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
Waste a part of electric energy, also result in solenoid excessive heating；Secondly, the control circuit of existing exchange door roller typically sets
There is 3-4 relay, its objective is to make motor can rotate forward, invert, and make interlock between relay, it is ensured that relay will not miss
Action, so makes circuit structure become complicated, and expense is the highest.
