Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1, 2, and 3: an automatic sucker supply device comprises a main shell 1, wherein the top of the main shell 1 is connected with a hopper 2, the hopper 2 is in a horn shape with an upward opening, a lifting motor 3 is arranged in the main shell 1, a working end of the lifting motor 3 is connected with a screw rod 4, the screw rod 4 is in threaded connection with a baffle plate 5 movably connected at a discharge port of the hopper 2, a guide rod 6 is also arranged in the main shell 1, the guide rod 6 is in sliding connection with a guide hole arranged on the baffle plate 5, the top end of the screw rod 4 is also provided with a limit block 7,

an ultraviolet lamp 21 is also provided within the main housing 1,

The utility model discloses suction head automatic supply device's working process as follows: all the suction heads 16 are first poured into the hopper 2, and the apparatus is activated by the control system,

firstly, the lifting motor 3 works to drive the screw rod 4 to rotate, when the screw rod 4 rotates forwards, the material blocking plate 5 connected with the screw rod 4 in a threaded mode cannot rotate under the action of the guide rod 6, so that the material blocking plate 5 can ascend relative to the hopper 2, and because the hopper 2 is in a horn shape with an upward opening, when the material blocking plate 5 ascends, the gap between the edge of the material blocking plate 5 and the inner wall of the hopper 2 is gradually enlarged, a part of suction heads 16 fall into the main shell 1 through the gap, and when the screw rod 4 rotates reversely, the material blocking plate 5 descends to block the suction heads 16 again;

the suction heads 16 entering the main shell 1 can be sterilized and disinfected under the action of ultraviolet light emitted by the ultraviolet lamp 21, meanwhile, the control system can also control the vibration motor 10 to work to drive the vibration plate 9 to swing back and forth, and the action of the vibration plate 9 can disperse a part of the suction heads 16 which are mutually nested together, so that each suction head 16 is independent; the separate suction head 16 will fall from the edge of the vibrating plate 9, into the transition 11,

the suction head 16 entering the transition part 11 enters the posture adjusting channel 14, the posture adjusting channel 14 is in a horn shape with an upward opening in the longitudinal direction, and the section of the posture adjusting channel 14 in the horizontal direction forms an outlet matched with the outer contour of the suction head 16, so that the posture of the suction head 16 can be automatically adjusted along with the shape of the posture adjusting channel 14 in the process of sliding downwards in the posture adjusting channel 14,

meanwhile, the adjusting cylinder 17 can drive the push plate 18 to perform pushing-out action according to a certain time interval, so that a part of suction heads 16 with unqualified postures are pushed to the direction of the insertion ports of the suction heads facing to the required end;

finally enters the suction head 16 of the inclined material channel 12 through the discharge hole 15, and the postures are consistent theoretically;

because the width of the inclined material channel 12 is m, the width of the widest part of the suction head 16 is n, and n is less than m and less than 2n, namely, the inclined material channel 12 only allows one suction head 16 to enter at a time; the suction head 16 entering the inclined material channel 12 is supported by the material guide slide rail 19 to slide downwards and finally slide into the material taking opening 20, and an operator directly extends the gun nozzle of the liquid transfer gun into the material taking opening 20 and inserts the gun nozzle into the insertion port of the suction head 16, so that the connection between the suction head 16 and the gun nozzle is completed;

after the lowermost nozzle 16 is removed, the upper nozzles 16 are sequentially lowered to ensure that there are always free nozzles 16 at the material removal opening 20.
