[0002] The pipe extrusion device is a commonly used equipment for processing plastic tubular parts. The heated plastic granular raw materials are extruded by the extruder equipment under high pressure, so that the plastic granular raw materials are extruded through the metal tubular mold to obtain continuous plastic tubular products.

[0022] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1-Figure 3As shown, the embodiment of the utility model proposes an extruded pipe cooling device, including a processing base 1, a uniform air cooling component and a pipe support component: the processing base 1 is fixedly connected to an extruder body 2; the uniform air cooling component includes an annular plate 3 rotatably connected to the circumferential outer wall of the extruder body 2 through an annular bearing, and a plurality of high-speed fans 4 are fixedly connected to the annular plate 3 through a fixed bracket, and an air guide duct 12 is arranged at the air outlet end of the high-speed fan 4, and a rotating driving component is arranged on the outer wall of the extruder body 2, and the rotating driving component includes a servo motor 8 installed on the outer wall of the extruder body 2, and the output end of the servo motor 8 is fixedly connected to a first gear 9, and an outer gear ring 10 is fixedly connected to the annular plate 3, and the outer gear ring 10 and the first gear 9 are meshed with each other;

[0024] When the pipe is extruded, the servo motor 8 and the plurality of high-speed fans 4 can be started, and the first gear 9 can be driven to rotate by the servo motor 8. The engagement of the first gear 9 and the outer gear ring 10 can be used to drive the annular plate 3 to rotate, so that the plurality of high-speed fans 4 on the annular plate 3 can perform surrounding air blowing cooling on the extruded pipe, so as to replace the cooling method of single-point air blowing, thereby improving the air cooling uniformity and air cooling effect of the pipe extrusion.

[0025] like Figure 1 and Figure 2 As shown, the pipe support assembly includes a rotating bracket fixedly connected to the processing base 1, a moving screw 5 is rotatably connected to the rotating bracket, a slider 6 is threadedly connected to the moving screw 5, a limiting rod 13 is fixedly connected to the bottom of the slider 6, a limiting slide rail 14 is fixedly connected to the processing base 1, the lower end of the limiting rod 13 matches the limiting slide rail 14, a supporting rod 7 is fixedly connected to the top of the slider 6, the upper end of the supporting rod 7 is arranged in an arc structure, and a silicone pad is arranged on the arc structure surface of the supporting rod 7, and a second gear 11 is fixedly connected to the end of the moving screw 5 close to the annular plate 3, and the second gear 11 is meshed with the outer gear ring 10;

[0026] When the outer gear ring 10 rotates, it can drive the movable screw 5 to rotate synchronously through its meshing with the second gear 11, so that the slider 6 on the movable screw 5 starts to move horizontally, and then drives the supporting rod 7 to move synchronously. The supporting rod 7 is used to fully support the extruded pipe to avoid deformation of the extruded pipe after cooling, thereby ensuring the processing quality of the extruded pipe.

[0027] The detailed working process of the utility model is as follows:

[0028] 1. When in use, the pipe is extruded through the extruder body 2. When the initial end of the pipe is extruded from the outlet end of the extruder body 2, the servo motor 8 and the plurality of high-speed fans 4 can be started, and the first gear 9 is driven to rotate by the servo motor 8. The engagement of the first gear 9 and the outer gear ring 10 is used to drive the annular plate 3 to rotate, so that the plurality of high-speed fans 4 on the annular plate 3 can perform surrounding air blowing cooling on the extruded pipe, so as to replace the cooling method of single-point air blowing, and improve the air cooling uniformity and air cooling effect of the pipe extrusion;

[0029] 2. When several high-speed fans 4 rotate to perform surrounding air blowing cooling on the extruded pipe, the meshing of the outer gear ring 10 and the second gear 11 can drive the movable screw 5 to rotate synchronously, so that the slider 6 on the movable screw 5 starts to move horizontally, and then drives the supporting rod 7 to move synchronously. The supporting rod 7 is used to fully support the extruded pipe to avoid deformation of the extruded pipe after cooling, thereby ensuring the processing quality of the extruded pipe.
