Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
A screw size automatic screening mechanism is shown in figures 1-5 and comprises a bottom plate 1, a first side plate 2, a second side plate 3 and a detection plate 4, wherein the first side plate 2 and the second side plate 3 are arranged on the bottom plate 1 in parallel to form a guide groove 5 for guiding the movement of a screw; the concave trough 22 that leads to of establishing in one side of the relative first curb plate 2 of second curb plate 3, pick-up plate 4 are the cuboid structure, and pick-up plate 4 sets up on second curb plate 3, and is located the top that leads to trough 22. Screws enter the guide groove 5 through the vibration disc in an arrayed mode, then enter the detection plate 4 for size detection, and can continue to move forwards along the guide groove 5 if the detection is qualified; otherwise, it will fall down in the trough 22 and leave the channel 5. According to the invention, through the distance between the screw rod of the screw and the edge of the screw head, when the distance is larger than the distance between the first side plate 2 and the second side plate 3, the screw can continuously move along the guide groove 5. Otherwise, the material falls from the material passing groove 22. As shown in fig. 3, when the screw enters the guide groove 5, the lower surface of the screw head is placed on the first side plate 2 and the second side plate 3, and the screw cannot fall from the gap between the two side plates. When the screw enters the detection part of the guide groove 5, as shown in fig. 4, if the size of the screw is qualified, the screw rod of the screw is attached to the first side plate 2, and the periphery of the screw head is attached to the detection plate 4, so that the screw smoothly passes through the detection part. As shown in fig. 5, if the screw head cannot be supported by the detection plate 4, the screw cannot be supported by the first side plate 2 alone, and falls down along the trough 22. When the screw rod and the screw head product are not coaxial, the screw can rotate due to the vibration transmitted by the vibration disc, and then the direction is changed to the unqualified side, and the screw still falls from the material passing groove 22.
