The fixed plate 8 and the movable plate 9 are also flush. A fixed guide bucket 11 is fixedly installed on the fixed plate 8, and the lower side of the front end plate of the fixed guide bucket 11 is movably abutted against the upper surface of the movable plate 9. The lower side of the fixed guide bucket 11 is mounted above the fixed spiral roller 4. A movable guide bucket 12 is fixedly installed on the movable plate 9, and the front side of the movable guide bucket 12 is movably abutted against the rear side wall of the front end plate of the fixed guide bucket 11. The lower side of the movable guide bucket 12 is mounted above the movable spiral roller 5. A mounting frame 13 is fixedly installed on the fixed plate 8, and the top plate of the mounting frame 13 is mounted above the movable plate 9. An electric screw pair 14 is fixedly installed on the mounting frame 13, and a limit plate 15 is fixedly installed on the output shaft of the electric screw pair 14. The left side of the limit plate 15 is mounted above the fixed spiral roller 4, and the right side of the limit plate 15 is mounted above the movable spiral roller 5. The rear side of the fixed guide bucket 11 and the rear side of the movable guide bucket 12 are both abutted against the front side wall of the limit plate 15. A pneumatic rod 6 is fixedly installed on the base 1, and the pneumatic rod 6 is mounted above the movable plate 9. A wedge seat 7 is fixedly installed on the output shaft of the pneumatic rod 6, and the wedge seat 7 is mounted above the fixed spiral roller 4 and the movable spiral roller 5.

A spline sleeve 22 is screwed onto the movable frame 3 via bearings. The spline shaft 21 is movably inserted into the spline sleeve 22. The spline sleeve 22 is connected to the front end shaft of the movable spiral roller 5 via a bevel gear set.
[0017] When using this device, the distance between the fixed spiral roller 4 and the moving spiral roller 5 is set according to the size of the bolt workpiece to be transferred. The locking nut 17 is loosened and the movable frame 3 is slid to adjust its position, thereby adjusting the position of the moving spiral roller 5. After adjustment, the locking nut 17 is tightened to complete the adjustment of the distance between the fixed spiral roller 4 and the moving spiral roller 5. The height position of the limiting plate 15 is set according to the size of the bolt workpiece to be transferred, and the height position of the limiting plate 15 is adjusted by the electric screw pair 14. The bolt workpiece is placed in the hopper composed of the fixed guide hopper 11, the moving guide hopper 12, and the limiting plate 15, so that the bolt workpiece is positioned between the fixed spiral roller 4 and the moving spiral roller 5, with the cap end of the bolt workpiece positioned on the fixed spiral roller 4 and the moving spiral roller 5, and the rod end of the bolt workpiece extending between the fixed spiral roller 4 and the moving spiral roller 5.

The fixed spiral roller 4 and the movable spiral roller 5 rotate in opposite directions. Through the cooperation between the rotating fixed spiral roller 4 and the movable spiral roller 5, the bolt workpiece mounted on the fixed spiral roller 4 and the movable spiral roller 5 is pushed backward. After the cap end of the bolt workpiece moves away from the area between the fixed guide bucket 11 and the movable guide bucket 12, the cap end of the bolt workpiece is clamped between the limiting plate 15 and the fixed spiral roller 4 and the movable spiral roller 5 until the bolt workpiece moves backward and abuts against the front side wall of the inclined wedge seat 7. During unloading, the inclined wedge seat 7 is moved by the pneumatic rod 6. The inclined wedge seat 7 moves away from above the fixed spiral roller 4 and the movable spiral roller 5, and then the bolt workpiece moves backward. After one bolt workpiece has moved backward, the inclined wedge seat 7 is reset by the pneumatic rod 6, thereby blocking the subsequent bolt workpiece.
