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.

[0029] 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.

[0030] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The shown embodiment is a rotary separation and screening device for fastener production, comprising a main frame 1 and a drive motor 2 mounted on the main frame 1, wherein the drive motor 2 is fixed to the outside of the main frame 1, and a rotary screening device 3 controlled by the drive motor 2 is mounted on one side of the upper surface of the main frame 1, and an electrically controlled side loading device 4 is arranged at the loading port of the rotary screening device 3 on the upper surface of the main frame 1, and a plurality of detachable bottom collecting boxes 5 are installed on one side of the rotary screening device 4 at the bottom of the main frame 1.

[0031] Working principle: people guide the fasteners into the electric-controlled lateral feeding device 4 at the specified position through the external guide rail, and then guide the fasteners from right to left into the rotating screening device 3 through the electric-controlled lateral feeding device 4, and the driving motor 2 controls the rotating screening device 3 to rotate, and then utilizes the rotation to guide the imported fasteners by gravity and sliding, controls the fasteners during the sliding process, and then screens the fasteners, guides them from the outside to the inside, and then slides and falls into the detachable bottom collecting box 5 to complete the screening.

[0032] In order to cooperate with lateral assembly, a lateral assembly groove 6 is opened on the main frame 1 at the assembly end of the rotary screening device 3. The rotary screening device 3 is movably assembled with the main frame 1 by inserting the assembly axes on the connecting surfaces on both sides into the mounting blind holes in the lateral assembly groove 6.

[0033] In order to cooperate with rotation adjustment, the rotary screening device 3 includes a central adjustment disk 31 with assembly shafts on both sides, a lateral fixed frame 32 fixed on the outer arc surface of the central adjustment disk 31, an external material guide cover shell 33 fixedly assembled on the outer side of the central adjustment disk 31 and an external screening frame 34 fixedly sleeved on the lateral fixed frame 32.

[0034] An annular adjustment tooth groove is provided on the outer surface of the central adjustment disk 31. The driving motor 2 is inserted into the annular adjustment tooth groove through the driving gear on the driving shaft to mesh with the central adjustment disk 31 for transmission. The central adjustment disk 31 is driven by the driving motor 2 to control the rotation of the central adjustment disk 31, and then the central adjustment disk 31 is used to control the rotation of the lateral fixed frame 32, so as to synchronously control the external screening frame 34 fixed by bolts on the outer side of the lateral fixed frame 32 to flip. When the external screening frame 34 flips to the unloading position of the electric-controlled lateral loading device 4, the electric-controlled lateral loading device 4 transports the fasteners to the upper surface of the external screening frame 34, and screens the material through the screening holes on the external screening frame 34. The fasteners with smaller structures fall onto the external screening frame 34 of the lower layer, and then slide to the right to the rightmost end due to gravity, and then flip upward with the external screening frame 34, and then slide from right to left for the second round of screening. According to the type and specification of the fasteners, different numbers of external screening frames 34 are set, and then interval settings are adopted, so that the effect of circulating screening can be achieved.

[0039] The fastener receives the limit of the external screening frame 34, and then slides toward the external material guide cover shell 33 while flipping the external screening frame 34. After sliding into the inside of the lateral material guide cover 331, it receives the lateral limit of the side guide cover 332, and then discharges the material along the discharge guide rail 333 to the detachable bottom collecting box 5.

[0040] In order to cooperate with the bottom sliding guide, a bottom translation guide rail 8 is installed at the bottom of the main frame 1 below the detachable bottom collection box 5, and a bottom translation support plate 9 for supporting the detachable bottom collection box 5 is slidably assembled inside the bottom translation guide rail 8.

[0041] The bottom translation support plate 9 is movably connected to the bottom translation guide rail 8 through the guide wheels at the bottom of both sides, and is adjusted and translated along the bottom translation guide rail 8.

[0042] In order to improve the structural stability and firmness in the assembled state, a downwardly recessed positioning groove 10 is opened inside the bottom translation support plate 9, and the detachable bottom collection box 5 is inserted into the positioning groove 10 and is clamped and limited with the bottom translation support plate 9 through the bottom positioning block 11.

[0043] In order to coordinate the weighing and measurement of the fasteners, an embedded weighing module 12 is installed on the upper surface of the bottom translation support plate 9 .

[0044] In order to cooperate with the outer side control, a flip control handle 13 is installed on the side wall of the detachable bottom collecting box 5.

[0045] By pulling the flip control handle 13, the removable bottom material collection box 5 and the bottom translation pallet 9 can be controlled to slide and adjust along the bottom translation guide rail 8, and the removable bottom material collection box 5 can be pulled out of the outside of the main frame 1, and then the removable bottom material collection box 5 can be easily separated from the bottom translation pallet 9.
