DETAILED DESCRIPTION

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0023] like Figures 1-3 As shown, this utility model provides a cooling and drying device for plastic tubes after shaping, including a water cooling mechanism 4 and an air cooling mechanism 5 arranged side by side, and a corrugated pipe transmission mechanism is provided at the input end of the water cooling mechanism 4 and the output end of the air cooling mechanism 5.

[0024] The transmission mechanism includes two transmission rollers 2 that are positioned vertically opposite each other;

[0025] like Figure 2 The water cooling mechanism 4 includes a base frame, a water pipe 7 is provided on the top of the base frame, the water pipe 7 is arranged in a figure-eight shape with the opening facing downwards, multiple water nozzles 8 are provided on the lower sides of the water pipe 7, and side supports 10 are vertically fixed on both sides of the water pipe 7. The side supports 10 are slidably installed on the base frame of the water cooling mechanism 4.

[0026] The base frame of the water cooling mechanism 4 is provided with a track 12 on both sides along the conveying direction, and the lower end of the side support 10 is provided with a track wheel 11, which is rolled on the track 12.

[0027] The inner side of the base frame of the water cooling mechanism 4 has two V-shaped inner plates, and each inner plate is provided with multiple rollers 9 along the conveying direction. When the corrugated pipe 1 is conveyed on the base frame, the rollers 9 arranged at an angle on both sides of the corrugated pipe 1 support the corrugated pipe 1 to prevent the corrugated pipe 1 from shifting during the conveying process.

[0028] like Figure 3 An air pipe 13 is located directly above the base of the air cooling mechanism 5. The air pipe 13 is arranged in a V-shape with its opening facing downwards. Multiple air nozzles 14 are located below both sides of the air pipe 13. Side supports 10 are vertically fixed on both sides of the air pipe 13, and the side supports 10 are slidably mounted on the base of the air cooling mechanism 5. The base structure of the air cooling mechanism 5 is the same as that of the water cooling mechanism 4. A track 12 is provided on both sides of the base of the air cooling mechanism 5 along the conveying direction. Track wheels 11 are provided at the lower end of the side supports 10, and the track wheels 11 are rotatably mounted on the track 12.

[0029] A side connecting rod 15 is fixedly connected between the side supports 10 of the water cooling mechanism 4 and the air cooling mechanism 5, thereby enabling the water pipe 7 and the air pipe 13 to move synchronously. A linkage bracket 17 is installed on the side connecting rod 15, and the linkage bracket 17 is threadedly driven by a nut and a lead screw 16, which is driven by a motor 18. The motor 18 drives the linkage bracket 17 and the side connecting rod 15 to move back and forth through the lead screw 16, thereby driving the water cooling mechanism 4 and the air cooling mechanism 5 to move back and forth along the conveying direction of the corrugated pipe 1. During the back and forth movement, the water cooling mechanism 4 and the air cooling mechanism 5 gradually cool the surface of the corrugated pipe 1, and the combination of water cooling and air cooling results in a better cooling effect.

[0030] A water tank 6 is also provided directly below the water cooling mechanism 4 and the air cooling mechanism 5 to recycle cooling water.

[0031] like Figure 4 The transmission roller 2 is a rotating body structure with a smaller middle and larger ends along the axial direction. Raised ribs 3 are arranged at equal intervals on the surface of the transmission roller 2. When conveying the corrugated pipe 1, the raised ribs 3 engage with the grooves on the surface of the corrugated pipe 1.

[0032] The upper and lower drive rollers 2 rotate in opposite directions, thereby driving the bellows 1 between the two drive rollers 2, thus effectively controlling the feed speed of the bellows.
