Screws are a common fastener that is widely used in machinery, electrical appliances and buildings. They are generally made of metal or plastic, cylindrical in shape, and have concave and convex grooves on the surface called threads. The thread rolling process is required in the screw production process. The thread rolling process is a processing method in which the blank between two washboards moves relative to each other, so that the screw can quickly form threads.

Specifically, the driving member comprises a motor 11, and the output end of the motor 11 is coaxially fixedly connected to the first gear 13.
[0019] As a preferred technical solution, a slide groove 18 is horizontally opened on one side of the fixed plate 9 close to the second rack 16, and a slider 17 is slidably connected in the slide groove 18. One side of the slider 17 is fixedly connected to one side of the second rack 16. Specifically, through the cooperation between the slider and the slide groove 18, the circumferential rotation of the second rack 16 is limited, so that the second rack 16 is subjected to the spiral transmission of the screw 14 to make a linear movement.
[0020] As a preferred technical solution, a guide rod 4 is horizontally provided on one side of the fixed plate 9 close to the lower wash board 3, and a through hole is provided on the upper wash board 2. The upper wash board 2 is slidably sleeved on the guide rod 4 through the through hole. Specifically, the guide rod 4 plays a guiding and limiting role in the moving direction of the upper wash board 2. Preferably, multiple groups of guide rods 4 and through holes can be set to make the horizontal sliding of the upper wash board 2 more stable and prevent the upper wash board 2 from flipping over.
[0021] As a preferred technical solution, a connecting plate 19 is provided on the side of the upper rubbing board 2 away from the fixed plate 9, and a plurality of brushes 12 are provided at the bottom of the connecting plate 19. A debris collection box 5 is provided on the base 1, and the debris collection box 5 is located on the side of the lower rubbing board 3 away from the fixed plate 9.

[0022] The first gear 13 is meshed with the second gear 15 to drive the rotating rod 8 to rotate, so that the lower scrubbing plate 3 rotates and the screws are dumped into the screw collection box 6, which is convenient for quickly collecting screws and improving working efficiency. The upper scrubbing plate 2 moves in the direction away from the fixed plate 9 again, and the second rack 16 slides in the opposite direction to make the lower scrubbing plate 3 rotate in the opposite direction back to the initial position.
[0023] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that 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.
