The vibration seat bottom plate 126 is screwed to the bottom plate 11 of the housing.

In operation, referring to fig. 1-13, screws are placed into the chute chamber 17, and an inclined U-shaped chute plate 172 is assembled into the chute chamber, and the screws are slid into the drum 18 from the U-shaped chute plate 172. After the power is turned on, the drum motor 111 operates to drive the driving gear 112 to operate, and the driving gear 112 operates to engage with the transmission gear 181 of the drum 18 and drive the drum to operate. The screw enters the inner wall of the drum, is driven to the top end along the drum by a scooping plate 182, and then freely falls into the screw machine track body 151 (guided by the track guide piece 155) from the drum scooping plate. The track body 151 of the screw machine is mounted on the screw machine track vibration seat 12, the vibration motor 121 in the track vibration seat 12 operates and vibrates, and the screws are guided to be conveyed out of the trough chamber one by one. The screws are individually inserted into the notches 1331 of the turntable 133 along the track body, and the first sensor 135 detects whether the screws are in place. After the screw is in place, the second sensor 138 detects the screw direction, so as to determine the rotation direction (direction a or direction B) of the rotary disc 133, and if the head of the screw (the portion with the hexagonal hole) faces the second sensor 138, the rotary disc 133 rotates in the direction a, and the air inlet at the corresponding position is ready to blow air. If the tail of the screw is facing the second sensor 138, the rotary disc 133 rotates in the direction B, and the air inlet at the corresponding position is ready to blow air. After the rotation to the position, the turntable 133 stops and waits, after receiving the signal, the air is blown to the designated position after correspondingly air intake, and after the blowing is finished, the turntable 133 continues to detect the rotation.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
