[0018] Furthermore, the material holding platform is provided in combination with the second material ejecting mechanism to realize automatic material collection of the pipe material that has completed the head shrinking process, thereby improving work efficiency.

[0019] Furthermore, the rotating setting of the V-shaped roller can reduce the rolling friction of the pipe material in contact with it, and the upper end of the first vertical plate is set to be higher than the upper end of the second vertical plate, which can perform a unilateral limiting effect on the pipe material when it rolls onto each V-shaped roller, ensuring that the pipe material can accurately fall onto each V-shaped roller.

When the first lifting mechanism lifts the tube to be processed, the tube to be processed can fall on the sliding guide slope. That is, the setting of the sliding guide slope can prevent the tube to be processed from being stably fed to each V-shaped roller due to the fact that the lifted tube to be processed fails to roll toward the V-shaped roller in time after the first lifting mechanism descends because the tube itself is not completely straight. The tube to be processed can fall on the sliding guide slope and roll along the sliding guide slope to each V-shaped roller, thereby improving the stable feeding effect of the tube to be processed.

[0022] Furthermore, a conveying mechanism is arranged at the pre-placement platform, and through the contact friction between the conveyor belt and the tube to be processed, the conveyor belt drives the tube to be processed to move forward together when it is conveyed forward, so as to achieve the effect of stably conveying the tube to be processed forward and ensure the continuous feeding effect of the first pushing mechanism.

[0023] Furthermore, the third material blocking bracket can ensure that the tube to be processed located on the placement and conveying plane can be stably placed, thereby preventing the tube to be processed from falling from the side due to rolling.

[0024] Furthermore, the setting of the positioning swing table can achieve the effect of aligning one end of each tube to be processed placed on the conveying plane, thereby improving the stable lifting of the tube to be processed and more precise position clamping of the clamped moving mechanism.

[0025] Furthermore, the setting of the sensor can sense whether there is a pipe to be processed at the first material blocking bracket, and control the conveying mechanism through the controller to convey the pipe to be processed forward in time, thereby ensuring a continuous and stable feeding effect of the pipe to be processed.

[0026] Furthermore, the second limiting protrusion arranged on the first material lifting guide slope can limit the rolling speed of the lifted tube to be processed at the end of the first material lifting guide slope due to gravity, reduce its fluctuation when rolling onto each V-shaped roller, make it stabilize on each V-shaped roller as soon as possible, and improve work efficiency.
