Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.
[0020] Please refer to Figure 1-6, the present utility model provides a technical solution: a hot drawing device for PE plastic pipes, including a bottom plate 1, a box body 2 is fixedly connected to the top of the bottom plate 1, a storage cavity 201 is penetrated and opened at the lower end of the box body 2, a double-shaft motor 21 is fixedly connected to the middle of the inner wall of the storage cavity 201, and reciprocating lead screws 22 are fixedly connected to both output ends of the double-shaft motor 21. Clamping assemblies 24 are threadedly connected to the rod walls of one ends of the two reciprocating lead screws 22;

Rotating rings 41 are fixedly connected to both sides of the gear ring 4, and the rotating rings 41 are all rotatably connected to the inner wall of the box body 2. A connecting block 42 is fixedly connected to the inner surface of the gear ring 4, a scraping knife 5 is fixedly connected to the top of the connecting block 42, and sliding rods 51 are fixedly connected to both bottom sides of the scraping knife 5.
[0022] Furthermore, movable support seats 11 are fixedly connected to both side edges of the top of the bottom plate 1, and both of the two movable support seats 11 are rotatably connected to the reciprocating lead screws 22. The movable support seats 11 can support the reciprocating lead screws 22.
[0023] Furthermore, limiting assemblies 23 are fixedly connected to the upper ends of the openings on both sides of the box body 2. Cooling fans 25 are installed inside both sides of the box body 2. A plurality of heating tubes 26 are installed on the inner surface of the box body 2 near both sides of the gear ring 4. The limiting assemblies 23 can limit the clamping assemblies 24. By starting the plurality of heating tubes 26, the plastic pipes can be heated by melting, and the hot-drawn PE plastic pipes can be cooled by the cooling fans 25.
[0024] Furthermore, a through hole 203 is penetrated and opened on one side of the groove 202 near the inside of the box body 2. Through the through hole 203, the gear ring 4 can be meshed with the transmission gear 32.
[0025] Furthermore, circular grooves 204 are opened on the inner surfaces of both sides of the box body 2 at the lower ends of the sliding rods 51, and the sliding rods 51 are all stuck in the circular grooves 204.

The rotating ring 41 drives the scraper 5 to rotate through the connecting block 42. The scraper 5 will slide along the circular groove 204 through the sliding rod 51. Thus, the scraper 5 scrapes the impurities and oxide layer on the outer wall of the PE plastic pipe, avoiding the influence of the oxide layer and impurities on the heating effect. Then start several heating tubes 26 to perform hot melting heating on the plastic pipe. After the PE plastic pipe is hot melt heated, immediately start the double-shaft motor 21 to drive the reciprocating screw rods 22 at both ends to rotate. The rotation of the reciprocating screw rods 22 at both ends stretches the clamping components 24 towards the outside of the box body 2. Then, through the cooling fan 25, the hot-stretched PE plastic pipe can be cooled.
