[0039] As Figure 3 And Figure 5As shown, each swing assembly includes a fixed plate 14 and a rotating strip 15, the top end of the fixed plate 14 is fixedly connected to the inside top end of the shaping box 2, the fixed plate 14 is designed to facilitate the fixation of the rotating strip 15, the rear end of the rotating strip 15 is rotatably connected to the front side of the fixed plate 14, and the rotating strip 15 is designed to connect the sprayer 16.

[0041] Working principle: when the PE pipe needs to be vacuum shaped, first insert a complete PE pipe into the inside of the shaping pipe 3, and tear off the hot residual material extruded from the PE pipe hot melting machine, and stick it to the PE pipe for traction to preheat it, then tear off the residual material from the traction PE pipe again and place it into the collecting frame 26, repeat the preheating for three to four times, the residual material and the traction PE pipe are difficult to tear off again, at this time, the extruded traction PE pipe and the newly extruded pipe can be connected, and the newly extruded PE pipe can be moved into the shaping pipe 3 in the vacuum shaping device for shaping. When shaping, the motor 20 drives the rotating piece 21 to rotate, thereby driving the driving sleeve 22, so that the driving sleeve 22 is continuously swung under the driving of the rotating piece 21, thereby making the sprayer 16 in a continuously swinging state. At this time, start the water pump 18, so that the water pump 18 sends the cooling water accumulated at the bottom end of the shaping box 2 into the sprayer 16 through the water pipe 17, and sprays it to the outside of the shaping pipe 3 through the sprayer 16, so as to shape the PE pipe in the shaping box 2. By continuously rotating the rotating piece 21 to drive the driving sleeve 22, the rotating strip 15 and the sprayer 16 are continuously swung, so that the water sprayed by the sprayer 16 can be more uniformly sprayed to the outside of the shaping box 2, thereby improving the cooling efficiency of the PE pipe.

[0042] When the shaped PE tube comes out of the shaping tube 3, the electric push rod 9 will push the sliding bar 10, allowing the sliding bar 10 to drive the fixed wheel 2 11 to support the bottom end of the PE tube, and in this process, the trapezoidal block 12 will also squeeze the fixed wheel 1 6 at the bottom end of the two clamping strips 5, so that the clamping strip 5 drives the fixed wheel 1 6 at the top to clamp the PE tube. By allowing the sliding bar 10 and the fixed wheel 2 11 to support the PE tube, and allowing the two clamping strips 5 to drive the fixed wheel 1 6 to clamp it, the PE tube can be prevented from being scratched or dented by the outlet of the vacuum shaping device during the removal process, thereby ensuring that the appearance and quality of the PE tube are not affected.
