Bar segment one coordinates realization location with positioning unit, and what bar segment one can be stable crosses positioning unit thus conveniently regulating.
In above-mentioned draught fan impeller processing unit (plant) in the position-limit mechanism of baffle plate, described spring is positioned at outside locating slot, and described bar segment one has the gear edge of protrusion, above-mentioned spring housing in bar segment two and the two ends of spring push up respectively be pressed in gear edge and guide post on.
Spring and gear are along between guide post and frame, and such setting makes spring and gear along more hidden, improves the compactedness of whole mechanism.
In above-mentioned draught fan impeller processing unit (plant) in the position-limit mechanism of baffle plate, described upper block is integral type structure.
In above-mentioned draught fan impeller processing unit (plant) in the position-limit mechanism of baffle plate, described guide post is integral type structure.
In above-mentioned draught fan impeller processing unit (plant) in the position-limit mechanism of baffle plate, described contiguous block being connected to the contact plate of a flexibility, above-mentioned upper block can be resisted against on contact plate.
Flexible contact plate can reduce the noise sent when contiguous block contacts with upper block.
In above-mentioned draught fan impeller processing unit (plant) in the position-limit mechanism of baffle plate, described contact plate is rubber slab.
In above-mentioned draught fan impeller processing unit (plant) in the position-limit mechanism of baffle plate, described contact plate is plank.
Compared with prior art, in this draught fan impeller processing unit (plant), the position-limit mechanism of baffle plate can be adjusted due to the position of upper block, thus improve the suitability of mechanism, can process the draught fan impeller of various different model.
Meanwhile, in adjustment during stop location, it is only necessary to applying external force and overcome spring force, easy to adjust have significantly high practical value.
