[0034] Example

[0035] like Figure 1-4 As shown, the present invention proposes a device for synchronous cooling and shaping of the inner and outer walls of a multi-layer composite PVC pipe, including a mounting base 1 and a production device 2. The mounting base 1 is provided with multiple conveying rollers 3 for conveying the pipe. The top of the mounting base 1 is provided with a fixing cover 4 for installation. The size of the fixing cover 4 is adapted to the length of the pipe. A sizing sleeve 5 for shaping is provided on one side of the production device 2. The side of the fixing cover 4 near the production device 2 is provided with an air-cooling structure 6 for accelerating the cooling speed and reducing the cooling speed difference.

[0036] The air-cooled structure 6 includes an air pump 601 for blowing air and a fixing ring 602 for installation. Multiple connecting sleeves 603 are movably mounted on the front of the fixing ring 602. The bottom of each connecting sleeve 603 is movably connected to the fixing ring 602. A connecting bracket 6013 is fixedly mounted on the outside of each connecting sleeve 603. The surface of the fixing ring 602 has four sliding grooves, with a scale line on one side of each groove. The scale line can be used to compare whether the distances moved by the multiple connecting brackets 6013 are consistent. A sliding block is movably mounted within each sliding groove and is fixedly connected to the connecting bracket 6013. A threaded rod 6012 is movably mounted on one side of the connecting bracket 6013. A guide block is fixedly mounted on one side of the connecting bracket 6013, and a groove is provided on one side of the guide block. A bearing is fixedly mounted within the groove, and the inner ring of the bearing is fixedly fitted onto the threaded rod 6012. The threaded rod 6012 can push the connecting sleeves 603, thereby changing the diameter of the circle formed by the multiple connecting sleeves 603. The outer surface of the threaded rod 6012... The device is equipped with a vertical plate 6011, which is fixedly connected to a fixing ring 602. The center of the vertical plate 6011 is provided with an internal threaded hole, which is movably connected to a threaded rod 6012. A connecting piece 604 is movably provided between adjacent connecting sleeves 603. The cooperation between the connecting piece 604 and the connecting sleeve 603 can expand the inner diameter of the circle formed by multiple connecting sleeves 603. The top and bottom inner walls of the connecting sleeve 603 are provided with sliding grooves 605. The top and bottom of the connecting piece 604 are fixedly provided with two sliders 606, which are movably connected to the sliding grooves 605. Multiple air collection pipes 607 are fixedly provided on the front of each connecting sleeve 603. A first air guide hose 608 is provided between each air collection pipe 607. A second air guide hose 609 is provided above one of the air collection pipes 607. A three-way pipe 6010 is provided at the other end of the second air guide hose 609. The three-way pipe 6010 is fixedly connected to the exhaust end of the air pump 601.

[0037] Both sides of the fixed cover 4 are provided with pipe holes. The other end of the tee pipe 6010 is fixed with a corrugated hose 8. The bottom end of the corrugated hose 8 is connected to the air guide pipe 7 by a clamp. The outer wall of the air guide pipe 7 is provided with several air outlet holes. The other end of the air guide pipe 7 is fixedly connected to one side of the production device 2, and the air guide pipe 7 is located at the center of the sizing sleeve 5. The cooperation between the corrugated hose 8 and the air guide pipe 7 can achieve cooling of the inside of the pipe, which can accelerate the discharge of high temperature inside the pipe and improve cooling efficiency.

[0038] In this embodiment, the cooling water pipe is first installed on multiple connectors outside the sizing sleeve 5. The other end of each connector is equipped with a spray nozzle for water cooling of the pipe. Then, the diameter of the circle formed by the multiple connecting sleeves 603 is adjusted according to the pipe specifications. Multiple threaded rods 6012 are rotated, driving the connecting frame 6013, which in turn drives the connecting sleeves 603. The multiple connecting sleeves 603 move closer or further apart. Multiple connecting parts 604 serve to connect and guide. When the inner diameter of the circle formed by the multiple connecting sleeves 603 matches the inner diameter of the pipe, the rotation of the threaded rods 6012 stops, and the pipe is extruded from the production device 2. The sizing sleeve 5 cools and sizing the pipe. The extruded pipe enters the fixed cover 4 and comes into contact with the multiple conveying rollers 3. In combination, the conveying roller 3 can convey the pipe material. The air pump 601 delivers air to the corrugated hose 8 and one of the air collection pipes 607, and then multiple air guide hoses 608 deliver it to other air collection pipes 607. Then, the cold air is blown onto the surface of the pipe material to achieve secondary cooling of the pipe material and promote the rapid evaporation of residual moisture on the surface of the pipe material, further reducing the temperature. The combination of the two can effectively improve the problem of uneven cooling speed caused by uneven water flow distribution when using water cooling alone. When the pipe material enters the fixed cover 4, the air in the air guide pipe 7 can blow towards the inner wall of the pipe material to achieve internal cooling of the pipe material, improve the discharge speed of internal high temperature, and improve cooling efficiency. After the pipe material is extruded, the conveying roller 3 is turned off and the corrugated hose 8 is separated from the air guide pipe 7. Finally, the conveying roller 3 is turned on again to output the pipe material.

[0039] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
