AI Technical Summary
In the existing technology, there is a lack of axial positioning of the lead screw after the motor stops rotating, resulting in poor stability after the lead bar moves.
The conveyor pipe is fixed on the mounting shaft, and the lead rod is positioned through the conveyor pipe. The torque is increased by combining the first and second gears. The mounting hole and magnetic absorption compression mechanism are set on the base. Axial fixation is achieved by using springs and positioning rods to avoid damage to the motor.
This improves the stability of the lead bars during the conveying process, avoids damage to the motor, and ensures that the motor can still work normally when it stops rotating.

Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.
[0026] This specific embodiment is a lead bar rotating conveying device, the structural schematic diagram of which is shown below. Figure 1 and Figure 2 As shown, the lead rod rotating conveying device includes a mounting shaft 8 and multiple conveying pipes 1 fixed in a ring array on the mounting shaft 8.

A drive mechanism is meshed below the first gear 5, and a positioning hole 4 is provided on the first gear 5. Multiple mounting holes 13 corresponding to the positioning holes 4 are provided in a ring array on the side wall of the base 6. A positioning rod 15 that is snapped into the positioning hole 4 is elastically inserted into the mounting hole 13, and a magnetic absorption shrinking mechanism is embedded and fixed in the mounting hole 13.
[0027] Multiple mounting plates 7 are fixed at equal intervals on the mounting shaft 8. Multiple grooves 9 are opened on the outer wall of the mounting plate 7.

The second gear 10 is meshed with the first gear 5. The first gear 5 is much larger than the second gear 10, which greatly increases the torque output by the motor 3. A drive shaft 11 is installed between the second gear 10 and the motor 3. A magnetic coupling 12 is installed on the drive shaft 11. When the first gear 5 stops rotating, the magnetic coupling 12 on the drive shaft 11 allows the shaft of the motor 3 to still rotate, avoiding the situation where the motor 3 cannot rotate and is damaged.
[0028] like Figure 3 and Figure 4 As shown, a spring 16 is embedded in the mounting hole 13 and abuts against the positioning rod 15.

The magnetic absorption shrinking mechanism includes an electromagnetic plate 17 fixed to the inner wall of the mounting hole 13 and a magnetic suction rod 14 installed on the inner wall of the positioning rod 15. The magnetic suction rod 14 passes through the spring 16 and is attracted and fixed to the electromagnetic plate 17. The external button closes the electromagnetic plate 17 in the mounting hole 13 near the conveying pipe 1. When the conveying pipe 1 moves to the top, the spring 16 pushes the positioning rod 15 to insert into the positioning hole 4, thereby keeping the first gear 5 and the mounting shaft 8 axially fixed, improving the stability after the lead rod moves. After the lead rod is removed by the clamping device, the electromagnetic plate 17 and the magnetic suction rod 14 are opened to attract each other, thereby causing the positioning rod 15 to retract into the mounting hole 13.
