[0002] Screws are indispensable industrial necessities in daily life. They are tools that use the physical and mathematical principles of the inclined plane, circular rotation, and friction to gradually fasten objects and machine parts. In order to classify screws, screw sorting devices are usually used to screen screws of different specifications.

[0003] Among them, a screw sorting device with announcement number CN202490781 U includes a square plate with baffles around its perimeter, the baffles being connected end to end; and a plurality of through holes are evenly distributed on the square plate.

[0004] However, existing screw sorting devices usually use flat screens to screen screws, so larger screws can easily clog the screen holes, requiring staff to clean the screens regularly. Utility Model Content

[0005] In view of the problems existing in the above-mentioned screw sorting devices, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a screw sorting device that solves the problem that existing screw sorting devices usually use flat screens to screen screws, so larger bolts can easily clog the screen holes, requiring staff to clean the screen regularly.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A screw sorting device includes a base, with two support plates fixedly connected to the upper surface of the base. Each of the two support plates has a first mounting hole on one side, and a screening cylinder is rotatably connected inside the two first mounting holes. A second mounting hole is opened on one side of the screening cylinder, and a screening screen is rotatably connected inside the second mounting hole. Some of the support plates are provided with a driving mechanism, and the screening cylinder and the screening screen are rotated by the driving mechanism. A support mechanism is provided between the screening cylinder and the screening screen.

[0009] Preferably, the drive mechanism includes a motor, a gear, an external gear ring, a first pulley, a second pulley, and a belt. The motor is fixedly connected to one side of one of the support plates, and the output end of the motor passes through one side of the support plate. The gear is fixedly sleeved on the output end of the motor. The external gear ring is fixedly sleeved on the outer surface of the screening cylinder, and the gear meshes with the external gear ring. The first pulley is fixedly sleeved on the rod wall at one end of the motor output end. The second pulley is fixedly sleeved on the outer surface of the screening screen, and the belt is sleeved on the outer surfaces of the first pulley and the second pulley.

[0010] Preferably, the support mechanism includes an annular slide rail and a slider.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model involves inserting a screw into the inside of a screening screen, and then rotating the screening cylinder and the screening screen. Here, the mesh openings of the screening screen are larger than the mesh openings of the screening cylinder. Subsequently, the smaller screw falls into the inside of the screening cylinder, thereby completing the screening work. At the same time, the rotation of the screening screen and the screening cylinder allows the screw stuck in the mesh openings to fall off when it is at the top.

[0016] 2. In this utility model, by starting the motor, the gear rotates, which in turn rotates the external gear ring, thereby driving the screening cylinder to rotate. Then, the screening screen can be rotated by the transmission of the first pulley, the second pulley and the belt, so as to facilitate the screening of screws. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a screw sorting device.

[0025] This utility model provides, for example Figure 1-3 The screw sorting device shown includes a base 1, on the upper surface of which two support plates 2 are fixedly connected. Each of the two support plates 2 has a first mounting hole on one side, and a screening cylinder 3 is rotatably connected inside the two first mounting holes. A second mounting hole is opened on one side of the screening cylinder 3, and a screening screen 4 is rotatably connected inside the second mounting hole. A driving mechanism is provided on some of the support plates 2, and both the screening cylinder 3 and the screening screen 4 are rotated by the driving mechanism. A support mechanism is provided between the screening cylinder 3 and the screening screen 4. Both the screening cylinder 3 and the screening screen 4 are cylindrical.

[0026] Insert the screw into the screen 4, then rotate the screen cylinder 3 and the screen 4. Here, the mesh of the screen 4 is larger than the mesh of the screen cylinder 3. The smaller screw then falls into the screen cylinder 3, thus completing the screening work. At the same time, by rotating the screen 4 and the screen cylinder 3, the screw stuck in the mesh can fall off when it is at the top.

[0027] To make the screening cylinder 3 and the screening screen 4 rotate, such as Figure 1-2 As shown, the driving mechanism includes a motor 5, a gear 6, an external gear ring 7, a first pulley 8, a second pulley 9, and a belt 10. The motor 5 is fixedly connected to one side of one of the support plates 2, and the output end of the motor 5 passes through one side of the support plate 2. The gear 6 is fixedly sleeved on the output end of the motor 5. The external gear ring 7 is fixedly sleeved on the outer surface of the screening cylinder 3, and the gear 6 meshes with the external gear ring 7. The first pulley 8 is fixedly sleeved on the rod wall at one end of the output end of the motor 5. The second pulley 9 is fixedly sleeved on the outer surface of the screening screen 4. The belt 10 is sleeved on the outer surfaces of the first pulley 8 and the second pulley 9.

[0028] Start motor 5 to make gear 6 rotate, which in turn makes external gear ring 7 rotate, thereby driving screening cylinder 3 to rotate. Then, the screening screen 4 can be rotated by the transmission of first pulley 8, second pulley 9 and belt 10, so as to facilitate the screening of screws.

[0029] To make screening mesh 4 more stable, such as Figure 2-3 As shown, the support mechanism includes an annular slide rail 11 and a slider 12. The annular slide rail 11 is fixedly sleeved on the outer surface of the screening cylinder 3, and the slider 12 is slidably engaged with the outer surface of the annular slide rail 11. The slider 12 is fixedly connected to the inner wall of the screening cylinder 3. The cross-section of the annular slide rail 11 is T-shaped.

[0030] The slider 12 can be used to provide support, thereby preventing one end of the screen 4 from collapsing during operation.

[0031] To facilitate screw movement, such as Figure 1-2 As shown, the base 1 is inclined.

[0032] Because the base 1 is tilted, the screw can be moved to one side.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
