AI Technical Summary

Technical Problem

In existing technologies, flaky and curled debris is easily stuck in the sieve holes or screw thread gaps due to its irregular shape. When screws are stacked, the gaps formed can trap debris, resulting in incomplete sorting and affecting screw quality.

Method used

A screw processing and sorting device was designed, comprising a sorting and discharge assembly with a screen plate rotatably connected by a rotating shaft. The screen plate is driven to flip by a gear and rack transmission and an eccentric shaft. Combined with a dust collection assembly and an automatic discharge structure, it can achieve efficient separation of debris and efficient sorting of screws.

Benefits of technology

It improves the thoroughness and efficiency of sorting, reduces debris residue, ensures screw quality, is suitable for efficient sorting of screws of different specifications, and enhances the stability and safety of the sorting device.

Abstract

This disclosure relates to the technical field of screw processing. One embodiment of this disclosure provides a screw processing and sorting device, which includes: a base plate, a sorting box, and a slag discharge port. The sorting box is fixed on the base plate, the slag discharge port is opened at the bottom of the sorting box, a sorting and discharge assembly is disposed in the sorting box, and a dust collection assembly is disposed at the top of the sorting box. The sorting and discharge assembly includes a screen plate, which is rotatably connected to the inside of the sorting box via a rotating shaft. A transmission gear is provided at one end of the rotating shaft of the screen plate. A crossbeam is provided on the side surface of the sorting box, and a movable frame is slidably connected to the crossbeam. A rack is provided at the upper end of the movable frame, and the rack meshes with the transmission gear. Through the above technical solution, the technical problems in the prior art that flaky and curled debris is easily stuck in the screen holes or screw thread gaps due to its irregular shape are solved; on the other hand, the gaps formed when screws are stacked will wrap around the debris, resulting in residues after sorting are also solved.
