Bead sorting machine

Abstract

The invention discloses a bead sorting machine. A support plate is arranged at the top of a base box through a vertical column, screw rods are arranged on the support plate through a group of rotatingmounting seats, spiral grooves are formed in the outer walls of the screw rods, a separation feeding assembly is arranged at one end of the upper portions of the screw rods, a guide plate is arrangedbelow the separation feeding assembly along the moving direction of the spiral grooves, and a visual detection assembly is arranged above the guide plate. An electromagnetic sorting mechanism abuts against the guide plate and is parallel to the screw rods, the electromagnetic sorting mechanism is provided with an electromagnet corresponding to the screw pitch of each spiral groove, and the electromagnets are used for driving a limiting end to separate beads in the spiral grooves to a discharge pipe below the support plate. The beads can be independently and regularly conveyed, and the movement of the beads is driven by the rotation of the screw rods, so that the problem that two beads meet is avoided, and the synchronous operation of the two screw rods greatly improves the working efficiency.

Description

technical field [0001] The invention relates to the field of bead sorting, in particular to a bead sorting machine. Background technique [0002] At present, some sorting techniques of beads use the difference in the diameter of the beads, and set holes with a certain small diameter so that the small beads can pass through and the large beads cannot pass through to sort the beads, but this method is limited to two different sizes of beads And it is not easy to achieve continuous screening; some use the principle that the beads are in the gravitational field or other force fields, because the position of the center of gravity is different, so the resultant force of the external field force is also different during the movement, and the trajectory and height of the beads are also different. Falling into different regions for classification, but this method is less accurate and difficult to grasp for beads with small differences in ball diameters. [0003] Therefore, a kind of...
