CN-122004076-A - Draw curtain stroke high accuracy control mechanism

Abstract

The invention belongs to the technical field of greenhouse, in particular to a curtain pulling stroke high-precision control mechanism which comprises a fixed support, wherein a main driving gear is arranged at the top of the fixed support, a less-eating-difference gear set is arranged at the top of the fixed support, the main driving gear is meshed with the less-eating-difference gear set, an adjusting driving plate is arranged in the middle of the less-eating-difference gear set, a locking bolt is arranged in the middle of the adjusting driving plate, a wiring terminal is arranged at the top of the fixed support, an error-proofing trigger piece is arranged at the top of the fixed support, the stroke control principle is that the main driving gear drives three less-eating-difference gear sets to rotate when rotating positively, when the preset stop position of a motor is reached, the grooves of the three driving plates are adjusted to the position that roller contacts can be just clamped into the grooves of the driving plate, then locking screws on the driving plates are screwed, and if the set motor is started when the wiring sequence is wrong, the stroke is driven reversely, the error-proofing trigger microswitch to stop equipment, so that the motor is prevented from damaging external facilities of users, and reverse rotation and debugging is identical.
