Working principle is described in detail
Each device all in initial position debug in advance, entire mechanism positions in tealeaves conveyer belt side suitably away from
From tealeaves drops in conveyer belt from the discharge port of tea frying machine, the lower section for connecing object spoon movement travel and being in discharge port of mechanism, passes
Send the top of band.When connecing object spoon and being in maximum stroke movement, tealeaves can just be fallen in the concavity slot for connecing object spoon；When connecing
When object spoon is in minimum movement stroke, connect the least significant end of object spoon just at the most edge of delivery section and in video camera just under
Side.
With the whole circle of motor rotation two for a research cycle, each circle is divided into half-turn and lower branch again to be illustrated.
Half way on first lap, motor rotate upper half-turn, the belt wheel transmission for being 1:1 by transmission ratio, matched driven V
The active V belt wheel of the active partial gear and longitudinal intermittent rotary mechanism of belt wheel and coaxially connected lateral interval telescoping mechanism
Half-turn is rotated simultaneously, active partial gear has rotated part with teeth, while driven stop being engaged with locks complete gear turn
Dynamic half-turn, by the Synchronous Transmission of crank, connecting rod slider push-pull rod, the object spoon that connects for catching tealeaves is pulled, tealeaves is rested on
The underface of visual pattern collecting mechanism；At the same time, the active V belt wheel of longitudinal intermittent rotary mechanism drives its matched
Driven V belt wheel rotates half-turn, changes transmission direction by bevel gear, drives the level-one of longitudinal intermittent rotary mechanism actively incomplete
Gear has turned half-turn with teeth, and matched level-one is driven only to lock complete gear rotation half-turn, coaxially connected second level with this
Active partial gear has turned anodontia half-turn, and second level is driven only to lock complete gear and do not rotate, and connects object spoon and does not rotate.
Half way under first lap, motor rotate the rotation that lower branch completes a whole circle, and the active of lateral interval telescoping mechanism is not
Complete gear rotates anodontia half-turn, does not realize transmission, and driven stop locks complete gear and do not rotate, and connects that object spoon is static to rest on vision
Immediately below image acquisition mechanism, the period completes the acquisition of tealeaves image at this time；The level-one active of longitudinal intermittent rotary mechanism is not
Complete gear has turned anodontia half-turn, is not driven, connects object spoon and do not rotate.
Second encloses upper half way, and motor rotates upper half-turn, and the active partial gear rotation of lateral interval telescoping mechanism is with teeth
Half-turn, while what is be engaged with only locks complete gear rotation half-turn, by the Synchronous Transmission of crank, connecting rod slider push-pull rod,
Catch the lower section for connecing object spoon and being sent back to discharge port of tealeaves；During sending back to, due to the one of longitudinal intermittent rotary mechanism
Grade active partial gear rotates half-turn with teeth, and driven stop of level-one locks complete gear rotation half-turn, and coaxially connected with this two
Grade active partial gear has turned half-turn with teeth, so second level is driven only to lock complete gear rotation half-turn, drive telescopic shaft with
Object spoon rotation half-turn is connect, so that tealeaves is poured into conveyer belt.
Second encloses lower half way, and motor rotates the rotation that lower branch completes a whole circle, and the active of lateral interval telescoping mechanism is not
Complete gear rotates anodontia half-turn, does not realize transmission, and driven stop locks complete gear and do not rotate, and connects that object spoon is static to rest on discharging
The lower section of mouth connects dress collection of the another side realization to tealeaves of object spoon (two sides for connecing object spoon is all in symmetrical concave face)；Between longitudinal direction
The level-one active partial gear of rotating mechanism of having a rest has turned anodontia half-turn, is not driven, connects object spoon and do not rotate.
As described above, in actual motion, the run duration in each period can be with for each periodic motion of entire mechanism
It is controlled and the control to motor speed.The movement that entire mechanism moves in circles, in the tea of visual pattern collecting mechanism acquisition
Leaf image when instrument thinks tea frying qualification after testing, controls motor stalls, and whole device stops fortune
Row.
