[0020] By moving the slide bar 72, the grinding wheel 74 can be brought into contact with the shaping cylinder 6, and then the motor 75 is started to rotate the grinding wheel 74, so that the grinding wheel 74 grinds the outer surface of the shaping cylinder 6, and the burrs on the outer wall of the shaping cylinder 6 can be removed, thereby facilitating the cooperation between the shaping cylinder 6 and the pipe to achieve sealing.

[0021] Among them, the clamping mechanism 4 includes a bidirectional screw 41, which is rotatably connected to the inner side of the movable frame 3, and both ends of the bidirectional screw 41 are threadedly connected with sliders 42, and the ends of the two sliders 42 away from the bidirectional screw 41 are fixedly connected with clamps 43, the inner side of the movable frame 3 is fixedly connected to a guide rail 45 arranged parallel to the bidirectional screw 41, and the two sliders 42 are slidably connected to the guide rail 45, and one end of the outer side of the movable frame 3 is fixedly installed with a motor 2 44, and the output shaft of the motor 2 44 is fixedly connected to the bidirectional screw 41, and the inner walls of the two clamps 43 are both arc structures, and the two clamps 43 are symmetrically distributed along the center line of the movable frame 3.

[0022] By starting the second motor 44, the bidirectional screw 41 can be rotated, which allows the two sliders 42 to slide toward each other along the guide rail 45, so that the two clamps 43 clamp the pipe, and then the cylinder 2 is controlled to drive the movable frame 3 to approach the shaping cylinder 6, so that the two clamps 43 drive the pipe to approach the shaping cylinder 6 and cooperate with it.

[0023] Among them, the grinding mechanism 7 also includes a wedge block 76, which is fixedly connected to the other end of the slide rod 72, and a return spring 77 is sleeved on the slide rod 72.
