Referring to fig. 4, the conveying track 240 is located below the two rollers 220, the conveying track 240 includes two parallel guide plates 241 and two parallel support plates 242 integrally connected to one end of the guide plates 241, the two guide plates 241 are located right below the two rollers 200, the two support plates 242 are located at positions where the lateral sides of the rollers 220 are biased downward, and as further described with reference to fig. 7, the top of the guide plates 241 is bent outward to form a guide section 2411, as shown in fig. 5, in the present embodiment, the guide section 2411 is in a circular arc shape, the guide plates 241 are configured such that when the screw 300 falls between the two rollers 220, a part of the screw slides down from the gap between the two rollers 220 and is placed between the two guide plates 241 under the combined action of the self-weight and the vibration of the tray body 100, the guide section 2411 can freely expand the aperture of the gap on the two guide plates 241, the screw 300 is made to fall more easily with its shank 320 between the two guide plates 241; the top of the supporting plate 241 is bent outwards to form a lifting section 2421, in this embodiment, the lifting section 2421 is a straight structure, and the lifting section 2421 is used for lifting the head 310 of the screw 300, so that the screw 300 maintains the posture that the head 310 faces downwards towards the upper rod part 320 between the two supporting plates 242, and the screw 300 is forced to move along the axial direction of the conveying rail 240 along with the vibration of the tray body 100; the rollers 220 have a height difference from the support plates 242, so that only the screws 300, whose shanks 320 were located between the two guide plates 241, can move further along the guide plates 241 between the support plates 242, while other screws 300, which cannot be aligned vertically on the rollers 220, cannot rest on the support plates 242.

The material returning plate 250 is fixedly connected to the mounting seat 210 and is inclined slightly downward toward the tray body 100, and the material returning plate 250 penetrates the material returning opening 150 and extends into the tray body 100, so that the screws 300 which cannot be left on the rollers 220 or the conveying rails 240 fall onto the material returning plate 250 and are guided by the material returning plate 250 to slide into the tray body 100.

The output assembly 200 further includes two stabilizing bars 260 fixedly mounted on the upper end surface of the mounting base 210, and the two stabilizing bars 260 are symmetrically disposed and respectively connected with the two guide plates 241 in an abutting manner for stabilizing the guide plates 241.

Referring to fig. 1, the output assembly 200 further includes a baffle 270 mounted at a position outside the mounting base 210 for shielding the mounting base 210 from the screws 300 falling out of the apparatus.

The working process of the screw vibrating disk of the invention is described below with reference to the accompanying drawings:

when the tray body 100 runs, the vibration module at the bottom of the tray body 100 drives the tray body 100 to run (the vibration feeding structure of the tray body 100 is the existing mature technology, and no redundant description is given), and at the same time, the motor 230 slowly rotates to drive the two rollers 220 to rotate from bottom to top, so that the screws 300 in the tray body 100 move towards the position of the blanking port 130 along the spiral material rail 110, due to the existence of the limiting port 120, only the screws 300 attached to the inner side wall part of the tray body 100 can continuously move towards the blanking port 130, so that the screws 300 moved to the position of the blanking port 130 approximately keep the posture of being axially arranged along the rollers 220, the screws 300 fall from the blanking port 130 to the gap between the two rollers 220, the screws 300 falling between the two rollers 220 make the rod part 320 of the screws 300 move downwards through the gap between the two rollers 220 under the synergistic effect of gravity and the vibration of the tray body 100, and finally move between the two guide plates 241, and keep the head part 310 erected posture of the rod, the screw 300 which keeps the head part 310 facing the upper rod part 320 downwards on the roller 220 moves gradually to be separated from the roller 220, and simultaneously, because the rod part 320 of the screw 300 is still positioned between the two guide plates 241, the screw 300 will continuously fall between the two support plates 242 and be lifted by the support plates 242, and the screw 300 which can not keep the vertical posture on the roller 220 can not be aligned with the position between the two support plates 242, so the screw 300 can fall onto the material returning plate 250 and be returned into the tray body 100 again; since the vibrating disk of the present embodiment always keeps the two rollers 220 rotating during operation, even if the screw 300 is jammed in the gap between the two rollers 220 at a moment, the moving roller 220 will give an upward resultant force to the screw 300 through contact friction, forcing the screw 300 to have a moving tendency of being disengaged upward from between the two rollers 220, and preventing the screw 300 from being jammed on the roller 200 and being unable to move forward.

Therefore, the screw vibration disk provided by the invention has at least the following beneficial effects:

the tray body 100 is provided with a blanking opening 130 at a position corresponding to the end of the spiral material rail 110, the output assembly 200 is correspondingly positioned below the blanking opening 130, the output assembly 200 comprises two rollers 220 capable of rotating oppositely, a conveying track 240 is arranged below the rollers 220, the conveying track 240 comprises a guide plate 241 directly below the two rollers 200 and a support plate 242 arranged at the side of the rollers 220 and biased downwards, the moving rollers 220 give an upward resultant force to the screws 300, so that the screws have a moving tendency of being separated upwards from the space between the two rollers 220, thereby preventing the screw 300 from jamming against the roller 200 and not moving further, the guide plate 241 will guide the orderly aligned screw falling onto the roller 220 and prevent the screw from deflecting, the support plate 242, which engages the guide plate 241, will again carry the ordered screw that is disengaged from the roller 220 so that the disordered screw cannot continue to move on the output assembly 200.

In light of the foregoing description of preferred embodiments in accordance with the invention, it is to be understood that numerous changes and modifications may be made by those skilled in the art without departing from the scope of the invention. The technical scope of the present invention is not limited to the contents of the specification, and must be determined according to the scope of the claims.
