[0033] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0034] The present utility model provides a Figures 1 to 4 kind of automatic electrode bender and its smooth turning and anti-extrusion damage mechanism as shown in the figure, including a turning frame 1. A fixed frame 2 is fixedly connected to the right end of the turning frame 1. A transmission assembly is arranged at the rear side of the turning frame 1 and the fixed frame 2. The transmission assembly includes a support bar 12, a first transmission shaft 15, a transmission motor 16, a first guide belt 17, a first conveyor belt 18 and a second conveyor belt 21. The first conveyor belt 18 is arranged inside the turning frame 1, and the second conveyor belt 21 is arranged inside the fixed frame 2. A support plate 11 is fixedly connected to the upper surface at the rear side of the turning frame 1 and the fixed frame 2. The support bar 12 is fixedly connected to the upper surface of the support plate 11. The first guide belt 17 is arranged on the side surface of the support bar 12. A limit plate 13 is fixedly connected to the upper surface of the support bar 12. A stop bar 14 is fixedly connected to the front side surface of the limit plate 13. The stop bar 14 is stuck at the front side of the first guide belt 17. The first transmission shaft 15 is rotatably connected to both the left and right ends between the limit plate 13 and the support plate 11. The transmission motor 16 is fixedly installed at the right end position on the upper surface of the limit plate 13. The output end of the transmission motor 16 is fixedly connected to the right first transmission shaft 15.

[0035] Among them, the first conveyor belt 18 and the second conveyor belt 21 are respectively driven by motors to rotate, and the electrode is conveyed from left to right. When the electrode moves to the surface of the first conveyor belt 18, since the first conveyor belt 18 is fan-shaped, the electrode is turned, improving the stability of the electrode turning and reducing the phenomenon of disordered electrodes. At the same time, the transmission motor 16 cooperates with the two groups of first transmission shafts 15 to drive the first guide belt 17 to slide on the surface of the support bar 12.

[0036] In addition, when the electrode near the edge of the first conveyor belt 18 may touch the edge of the turning frame 1 during the turning process, at this time, since the first guide belt 17 rotates synchronously with the first conveyor belt 18 and the second conveyor belt 21, the first guide belt 17 drives the end of the electrode to move, avoiding wear at the end of the electrode and reducing the phenomena of damaged electrodes and stuck electrodes.

[0037] Refer to Figure 1 、 Figure 5 and Figure 6 As shown in FIGS.

[0038] Specifically, the motor drives the third conveyor belt 31 to convey the welding rods to the right. The driving motor 37 drives the third transmission shaft 36 to rotate. The third transmission shaft 36 cooperates with two second transmission shafts 35 on the same side to drive the second guiding belt 38 to rotate. The second guiding belt 38 converges the welding rods inward, thereby facilitating the alignment of the disordered welding rods and being more conducive to the subsequent sorting and packing of the welding rods.

[0039] The working principle of the present utility model: Through the fan-shaped first conveyor belt 18, the welding rods are automatically turned, avoiding the phenomenon of disordered welding rods. At the same time, the first guiding belt 17 on the side wall rotates synchronously with the first conveyor belt 18 and the second conveyor belt 21, avoiding the friction between the surface welding rods and the side walls of the turning frame 1 and the fixing frame 2, avoiding wear on the welding rods, and avoiding the phenomenon of stuck bars, realizing the smoothness and non-damage of the welding rods during the turning process, greatly improving the production efficiency and reducing the rejection rate.

[0040] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and do not limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
