The automatic circular saw offline material preparation device includes a frame 1, a V-shaped roller 2, a material turning hook 3, a material turning cylinder 4, a rotating shaft 5 and a material preparation grid 8. There are multiple V-shaped rollers 2 that are evenly spaced and arranged on the top of the frame 1 for conveying pipe blanks. The rotating shaft 5 is arranged along the arrangement direction of the V-shaped roller 2 and is rotatably connected to the top of the frame 1. There are multiple material turning hooks 3 and they are respectively arranged between two adjacent V-shaped rollers 2. A transmission sprocket 22 is fixedly mounted on the side of the V-shaped roller 2 away from the rotating shaft 5, and a cover shell 7 is provided on the frame 1 to cover the outside of the transmission sprocket 22.

[0022] One end of the material turning hook 3 is provided with an upward hook-shaped portion, and the other end of the material turning hook 3 is fixedly connected to the rotating shaft 5. The material turning cylinder 4 is fixedly connected to the frame 1, and the piston rod of the material turning cylinder 4 extends upward and is hinged on the hook-shaped portion of one of the material turning hooks 3. The top of the piston rod of the material turning cylinder 4 is provided with a hinge seat 41, and the hinge seat 41 is U-shaped. The hook-shaped portion of the material turning hook 3 is located in the hinge seat 41 and is hinged to the hinge seat 41 through a pin. The material preparation grid 8 is arranged on one side of the frame 1, and the top opening of the material preparation grid 8 is close to the rotating shaft 5. The end of the material turning hook 3 away from the hook-shaped portion is provided with a clamp-shaped portion 31, and the clamp-shaped portion 31 is U-shaped. The clamp-shaped portion 31 is sleeved on the rotating shaft 5, and the clamp-shaped portion 31 is fixedly connected to the rotating shaft 5 by locking the bolts connecting the two side plates of the clamp-shaped portion 31. Three bearing seats 6 are provided on the top of the frame 1 , and the rotating shaft 5 is sequentially inserted into the bearings of each bearing seat 6 so as to be rotatably connected to the frame 1 .

[0023] The automatic circular saw conveyor roller of the present embodiment further comprises a reduction motor, which is connected to the drive sprocket 22 of each V-shaped roller 2 through a chain drive. A limit plate 9 is provided at one end of the frame 1 away from the automatic circular saw conveyor roller.
