Technical Field

[0001] This utility model relates to the field of PE pipe technology, and in particular to a cooling device for PE pipe production. Background Technology

[0002] PE pipe is a plastic pipe made from polyethylene resin as the main raw material, with the addition of antioxidants, ultraviolet stabilizers and other auxiliary materials, through an extrusion process.

[0003] The cooling device in PE pipe production is a crucial link in the entire extrusion production line. It directly affects the dimensional stability, roundness, surface quality, residual stress, and final performance of the pipe. However, current cooling devices often cool PE pipes by spraying water onto the surface of the pipe. This cooling method is insufficient and uneven, which can lead to problems such as pipe deformation, surface defects, and internal stress concentration. Therefore, a cooling device for PE pipe production is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing cooling devices that cool PE pipes by spraying water onto the surface of the pipes. This cooling method is insufficient and uneven, leading to problems such as pipe deformation, surface defects, and internal stress concentration.

[0008] Preferably, the lifting mechanism includes a second drive motor mounted on the top of the L-shaped block, the L-shaped block is rotatably connected to a second threaded rod fixed to the output end of the second drive motor, the second threaded rod is threadedly connected to a lifting block, and one side of the lifting block is fixedly connected to the placement frame.

[0009] Preferably, the placement frame has a circular hole, a spring is fixedly connected to the inner bottom of the placement frame, and a trapezoidal block is fixedly connected to one end of the spring.

An L-shaped block 3 is provided on one side of the rectangular block 2. A placement frame 4 is provided on one side of the L-shaped block 3. When the PE pipe needs to be cooled after processing, it is placed into the placement frame 4, so that the placement frame 4 can drive the PE pipe to move.

[0016] A rectangular groove 5 is provided on one side of the rectangular block 2. A moving mechanism is provided on one side of the rectangular block 2, which moves the placement frame 4 by driving the L-shaped block 3. After the PE pipe is cooled, the moving mechanism moves one end of the PE pipe to the outside of the cooling box 1.

[0017] The L-shaped block 3 is equipped with a lifting mechanism that drives the placement frame 4 to move up and down. A rectangular plate 6 is fixedly connected to one side of the cooling box 1. A water pump 7 is installed on the rectangular plate 6. Water is added to the cooling box 1 by the water pump 7. Then, the PE pipe on the placement frame 4 is immersed in the water by the lifting plate, so that the PE pipe can be cooled fully and evenly.

[0018] The moving mechanism includes a first drive motor 8 installed in a rectangular slot 5. The output end of the first drive motor 8 is connected to a first threaded rod 9. The first threaded rod 9 is threadedly connected to an L-shaped block 3. By rotating the first threaded rod 9, the L-shaped block 3 can drive the placement frame 4 to move. After the PE pipe is cooled, the PE pipe is moved so that one end comes outside the cooling box 1, making it easy to take it out.

[0019] One end of the L-shaped block 3 is slidably connected to the rectangular groove 5. A circular opening 10 is provided on one side of the cooling box 1, and a rectangular opening 11 is provided on the other side of the cooling box 1. The PE pipe enters the cooling box 1 through the circular opening 10. After cooling is completed, the PE pipe is taken out through the rectangular opening 11.

[0020] The lifting mechanism includes a second drive motor 12 mounted on the top of the L-shaped block 3. The L-shaped block 3 is rotatably connected to a second threaded rod 13 fixed to the output end of the second drive motor 12. The second threaded rod 13 is threadedly connected to a lifting block 14. One side of the lifting block 14 is fixedly connected to the placement frame 4. The rotation of the second threaded rod 13 allows the lifting block 14 to drive the placement frame 4 to rise and fall. After the PE pipe is placed on the placement frame 4, the placement frame 4 drives the pipe to descend and immerse it in water for cooling.

[0021] The placement frame 4 has a circular hole 15. A spring is fixedly connected to the bottom of the placement frame 4. A trapezoidal block 16 is fixedly connected to one end of the spring. The PE pipe enters the circular hole 15, and the spring causes the trapezoidal block 16 to fix the PE pipe.

[0022] A water pump 7 is fixedly connected to a water suction pipe on one side and a water outlet pipe on the other side. One end of the water outlet pipe extends into the cooling tank 1. Water is drawn from the water pump 7 through the water suction pipe and then placed into the cooling tank 1.

[0023] A drain pipe 17 is fixedly connected to one side of the cooling box 1. A solenoid valve 18 is installed on the drain pipe 17. After cooling is completed, water is discharged from the drain pipe 17 through the solenoid valve 18.

[0024] The specific model and specifications of the first drive motor 8 and the second drive motor 12 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0025] The working principle of this utility model: The processed PE pipe enters the cooling box 1 through the circular opening 10 until the PE pipe passes through the circular hole 15 on the placement frame 4. The elasticity of the spring allows the trapezoidal block 16 to fix the PE pipe. Subsequently, the second drive motor 12 drives the second threaded rod 13 to rotate, the second threaded rod 13 drives the lifting block 14 to descend, the lifting block 14 drives the placement frame 4 to descend, the placement frame 4 drives the PE pipe to descend, allowing it to be completely immersed in water. After cooling, the lifting block 14 drives the placement frame 4 to rise, the first drive motor 8 drives the first threaded rod 9 to rotate, the first threaded rod 9 drives the L-shaped block 3 to move, the L-shaped block 3 then drives the placement frame 4 to move until one end of the PE pipe on the placement frame 4 protrudes from the rectangular opening 11, and the staff removes it.
