These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Figure 1 , Figure 2 and Figure 3 The fastener conveying equipment shown in the figure has an automatic screening and sorting device, including a horizontal main frame 1 and an electrically controlled conveyor belt 2 installed on the horizontal main frame 1, an upper assembly frame 3 with an N-shaped structure is fixedly mounted on the upper surface of the horizontal main frame 1, an electrically controlled flip frame 4 is movably mounted on the upper assembly frame 3, a detachable screening plate 5 is fixedly mounted on the outer side surface of the electrically controlled flip frame 4, and a lateral material guide frame 6 is movably mounted on the upper end of the horizontal main frame 1 located on one side of the electrically controlled flip frame 4.

[0029] Working process: the fasteners are adjusted in translation through the electric-controlled conveyor belt 2, and then receive the screening material from the electric-controlled flip frame 4. A plurality of upper assembly frames 3 are arranged at different positions of the horizontal main frame 1, and then detachable screening plates 5 with different gaps are installed on different electric-controlled flip frames 4. Fasteners of different specifications are screened at different positions, and the gap gradually decreases along the traveling direction of the electric-controlled conveyor belt 2.

[0030] In order to facilitate assembly and adjustment, an annular assembly groove for mounting the electric-controlled flip frame 4 is provided at the upper end of the upper assembly frame 3 .

[0031] In order to cooperate with the rotation control, the electrically controlled flip frame 4 includes a transverse assembly cylinder 41 movably mounted inside the annular assembly groove, an external assembly frame 42 fixed on the outer arc surface of the transverse assembly cylinder 41, an external worm gear 43 axially fixed on the outer sides of the two ends of the transverse assembly cylinder 41, a transverse assembly seat 44 fixed on both sides of the upper end of the upper assembly frame 3, and an electrically controlled worm 45 installed inside the transverse assembly seat 44.

[0032] In order to facilitate loading and unloading, the detachable screening plate 5 is fixedly installed on the inner side of the external assembly frame 42 by means of bolts.

[0033] In order to cooperate with installation and screening, the detachable screening plate 5 includes an external fixing frame 51 bolted to the inner side of the external assembly frame 42, 6 internal screening frames 52 fixed inside the external fixing frame 51, and a detachable lateral material removing arm 53 inserted and fixed on the inclined surfaces on both sides of the internal screening frame 52.

[0034] The fasteners are translated along with the electrically controlled conveyor belt 2 and then pass through the gap inside the internal screening frame 52 to perform a screening operation. Fasteners that meet the specifications pass through the gap, while fasteners that do not meet the specifications are blocked.

[0035] For installation, lateral assembly grooves for fixing the detachable lateral material-moving arms 53 are provided on the inclined surfaces on both sides of the internal screening frame 52 , and internal threaded assembly blind holes communicating with the inside of the lateral assembly grooves are provided inside the internal screening frame 52 .

[0036] In order to facilitate loading and unloading, the assembly surface of the detachable lateral material-moving arm 53 has an internal limit frame 54 of an integral structure, and the internal thread of the internal thread assembly blind hole is inserted with a limit bolt 7 that matches the internal limit frame 54.

[0037] The limiting bolt 7 is screwed into the internal thread assembly blind hole and then passes through the internal limiting frame 54, so as to fix the detachable lateral material removing arm 53 at the lateral assembly groove position.

[0038] In order to cooperate with the flipping control, arc guide rails 8 for installing the lateral material guide frame 6 are fixedly installed on both sides of the horizontal main frame 1, and a lateral control worm 9 for controlling the lateral material guide frame 6 is provided on the outer arc surface of the arc guide rail 8.

[0042] When the pressure of the gravity sensor modules 11 on the upper surface of more than half of the detachable lateral material removing arms 53 gradually increases, proving that the screening port is blocked, the electrically controlled worm 45 will be started at this time, and the electrically controlled worm 45 will drive the external worm gear 43 to rotate, thereby synchronously controlling the rotation of the horizontal assembly cylinder 41, driving the external assembly frame 42 to flip counterclockwise, and flipping the external assembly frame 42 originally vertically at the bottom upward, thereby guiding the fasteners blocking the surface upward, and then the fasteners slide onto the detachable screening plate 5, and are guided outward through the detachable screening plate 5.
