[0002] Plastic pipes are chemical building materials made of high-tech composites. Chemical building materials are the fourth largest category of new building materials in contemporary times after steel, wood, and cement. Chemical building materials have made great progress and rapid development in my country, especially the widespread use of new environmentally friendly plastic pipes, which has set off a revolution to replace traditional building materials. Plastic pipes are widely used in building water supply and drainage, urban water supply and drainage, and gas pipes due to their advantages such as low water loss, energy saving, material saving, ecological protection, and convenient completion. They have become the main force of urban construction pipelines in the new century.

[0003] The currently published patent: CN215040140U, discloses a forming device for PVC plastic pipe production. The coolant in the box can be extracted through the pump body to cool the plastic pipe. At the same time, the fan is used to blow out cold air to dry the moisture on the surface of the plastic pipe, and the temperature can be lowered again. The cooling effect is good, which can increase the forming speed of PVC plastic pipes and improve the production quality of PVC plastic pipes.

[0004] Based on the above search, it was found that the above patent has the following problems when used: when the forming device is in use, the fan can blow out cold air to dry the moisture on the surface of the plastic pipe, and at the same time it can cool it down again, with a good cooling effect. Since the air disc is fixedly installed on the upper side of the pipe, the fan can only blow air on the upper side of the pipe, and the cold air cannot be blown evenly on the surface of the pipe, which affects the uniformity of the pipe cooling, easily causes the pipe to deform, and reduces the production quality of the pipe. Utility Model Content

[0005] The purpose of the present utility model is to solve at least one of the technical problems existing in the prior art and to provide a PVC pipe production and molding equipment, which can solve the problem that since the wind disk is fixedly installed at the upper side of the pipe, the wind can only be blown at the upper side of the pipe through the fan, and the cold air cannot be blown evenly on the surface of the pipe, which affects the uniformity of pipe cooling, easily causes pipe deformation, and reduces the production quality of the pipe.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a PVC pipe production and molding equipment, comprising an extruder body and a pipe cooling and molding device; PVC pipe is extruded at the left end of the extruder body; the pipe cooling and molding device comprises a molding frame, two mounting bases, a cooling ring sleeve, an exhaust pipe, a cooling fan and a connecting pipe, the molding frame is arranged at the left end of the extruder body, the two mounting bases are fixedly connected to the top of the molding frame, the cooling ring sleeve is fixedly connected to the top of the two mounting bases, the interior of the cooling ring sleeve is a hollow structure, the inner wall of the cooling ring sleeve is evenly provided with exhaust holes, the exhaust pipe is fixedly connected to the surface of the cooling ring sleeve, the cooling fan is fixedly installed on the bottom wall of the molding frame, the left end of the connecting pipe is fixedly installed on the output end of the cooling fan, and the right end of the connecting pipe is fixedly connected to the surface of the exhaust pipe.

The molding frame 3 is arranged at the left end of the extruder body 1, the two mounting bases 4 are fixedly connected to the top of the molding frame 3, the cooling ring sleeve 5 is fixedly connected to the top of the two mounting bases 4, the interior of the cooling ring sleeve 5 is a hollow structure, the inner wall of the cooling ring sleeve 5 is evenly provided with exhaust holes 6, the exhaust pipe 7 is fixedly connected to the surface of the cooling ring sleeve 5, the cooling fan 8 is fixedly installed on the bottom wall of the molding frame 3, the left end of the connecting pipe 9 is fixedly installed on the output end of the cooling fan 8, and the right end of the connecting pipe 9 is fixedly connected to the surface of the exhaust pipe 7.

[0025] After the staff starts the cooling fan 8, the cooling fan 8 discharges cold air into the interior of the exhaust pipe 7 through the connecting pipe 9. The cold air enters the interior of the cooling annular sleeve 5 through the exhaust pipe 7 and is ejected toward the center of the cooling annular sleeve 5 through the exhaust hole 6. After the PVC pipe 2 is extruded from the left end of the extruder body 1, the PVC pipe 2 gradually moves to the left and enters the interior of the cooling annular sleeve 5. At this time, the cold air ejected from the exhaust hole 6 can be blown on the surface of the PVC pipe 2, thereby cooling the PVC pipe 2. In this way, the cold air can be evenly blown on the surface of the PVC pipe 2, thereby ensuring that the cooling speed of different positions of the PVC pipe 2 is the same, thereby improving the uniformity of cooling of the PVC pipe 2, avoiding deformation of the PVC pipe 2, and improving the production quality of the PVC pipe 2.

[0026] Two chutes 10 are provided on the top of the extruder body 1, and two sliders 11 are slidably connected inside the chutes 10. The internal threads of the two sliders 11 are sleeved with double-threaded rods 12, and the front and rear ends of the double-threaded rods 12 are provided with threads in opposite directions. The rear end of the double-threaded rods 12 rotates through the interior of the forming frame 3 and extends to the outside. The rear end of the double-threaded rods 12 is fixedly connected to a circular turntable 13, and the tops of the two sliders 11 are fixedly connected to arc-shaped support blocks 14. The surfaces of the two arc-shaped support blocks 14 are provided with three spherical grooves 15. The internal sliding installation of balls 16 is carried out in the spherical grooves 15.

[0027] The PVC pipe 2 can be supported by the two arc-shaped support blocks 14 during its gradual movement to the left, and the ball 16 can be driven to roll during the movement of the PVC pipe 2. The staff rotates the double-threaded rod 12 through the circular turntable 13. The rotation of the double-threaded rod 12 can drive the two sliders 11 to slide relative to and opposite to each other. The sliding of the two sliders 11 can drive the two arc-shaped support blocks 14 to slide relative to and opposite to each other to support PVC pipes 2 of different diameters, thereby increasing the applicable scope of the molding equipment, so that the molding equipment can cool and mold PVC pipes 2 of different diameters.

[0028] Working principle: After the staff starts the cooling fan 8, the cooling fan 8 discharges cold air into the exhaust pipe 7 through the connecting pipe 9, and the cold air enters the interior of the cooling ring sleeve 5 through the exhaust pipe 7 and is ejected to the center position of the cooling ring sleeve 5 through the exhaust hole 6. The PVC pipe 2 gradually moves to the left and enters the interior of the cooling ring sleeve 5. At this time, the cold air is ejected from the exhaust hole 6 and can be blown on the surface of the PVC pipe 2 for cooling. In the process of the PVC pipe 2 gradually moving to the left, it can be supported by the two arc-shaped support blocks 14, and the ball 16 can be driven to roll in the process of the movement of the PVC pipe 2. The staff rotates the double-threaded rod 12 through the circular turntable 13. The rotation of the double-threaded rod 12 can drive the two sliders 11 to slide relative to and oppositely. The sliding of the two sliders 11 can drive the two arc-shaped support blocks 14 to slide relative to and oppositely to support PVC pipes 2 of different diameters, thereby increasing the applicability of the molding equipment so that the molding equipment can perform cooling molding on PVC pipes 2 of different diameters.
