Description

Technical Field

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

[0002] PE pipe cooling equipment mainly involves the cooling process in the production of polyethylene (PE) pipes, and its development relies on advancements in plastic processing technology, materials science, and industrial automation. In the pipe production process, the cooling of pipe fittings is crucial. Rapid and effective cooling of fittings ensures uniform shrinkage, which is of great significance for improving product qualification rates, saving manpower, and increasing labor productivity.

[0003] Most existing PE pipe cooling equipment involves immersing the pipe in coolant for cooling. This method results in slow cooling speed and uneven cooling, affecting efficiency. Utility Model Content

[0004] To overcome the shortcomings of uneven cooling in most existing PE pipe cooling equipment, the technical problem to be solved is to provide a cooling equipment for PE pipe production.

[0005] The technical solution is as follows: A cooling device for PE pipe production includes a frame, a liquid storage tank, a base frame, a support, a cylinder, a tree-shaped frame, extrusion blocks, support columns, cooling cylinders, a motor, and magnets. The four frames are symmetrically distributed, and a liquid storage tank is fixedly connected between the four frames. The bottom of the liquid storage tank is rotatably connected to the base frame. A support is fixedly connected to the rear side of the liquid storage tank. A cylinder is installed on the upper part of the support, and the cylinder is perpendicular to the top of the liquid storage tank. The cylinder's extension rod is connected to the tree-shaped frame. Two extrusion blocks are symmetrically fixedly connected to the bottom of the tree-shaped frame. A support column is fixedly connected through the middle of the base frame. Two cooling cylinders are also symmetrically connected through the base frame. The four cooling cylinders are distributed circumferentially outside the support columns, and the cooling cylinders are located inside the liquid storage tank and perpendicular to the extrusion blocks above. A motor is installed on the top of the support columns, and the motor output shaft is connected to the four cooling cylinders respectively. Magnets are fixedly connected to the outer side of the cooling cylinder and the inner side of the liquid storage tank that are close to each other.

[0006] Furthermore, it also includes hinges, torsion springs, and opening / closing plates. Two hinges are symmetrically fixed to the inner side wall of the bottom frame. The hinges are divided into two parts, which are connected by a torsion spring. An opening / closing plate is fixed to the other end of the hinge, and the opening / closing plate is located at the bottom of the cooling cylinder.

[0007] Furthermore, it also includes a sliding frame, a spring, a slider, and a limiting block. A sliding frame is symmetrically fixed to the lower part of the outer wall of the liquid storage tank. A spring is provided inside the sliding frame on the side near the liquid storage tank. The other end of the spring is connected to a slider, and the slider is slidably disposed inside the sliding frame. The other end of the slider is fixed to a limiting block, which is located at the bottom of the liquid storage tank and at the bottom of the opening and closing plate.

[0008] Furthermore, it also includes a transmission block and a propulsion block. The transmission block is fixedly connected to the rear side of the tree-shaped frame. The transmission block passes through the middle of the support and extends downward. The other end of the transmission block is fixedly connected to a propulsion block, which is located between the tops of the two limiting blocks.

[0009] Furthermore, it also includes a controller, which is installed in the middle of the front side of the liquid storage tank. The controller is electrically connected to the cylinder and the motor.

[0010] Furthermore, both the cooling cylinder and the liquid storage tank are made of corrosion-resistant materials.

[0011] This invention has the following advantages: The invention uses a cylinder telescopic rod to drive the extrusion block and the push block to press down, so that the limiting block moves back and forth at the bottom of the opening and closing plate, achieving the effect of automatic material picking. In addition, the motor drives the cooling cylinder to rotate, making the cooling effect more uniform and faster. Attached Figure Description

[0019] A cooling device for PE pipe production, such as Figures 1-3 and Figure 5As shown, the device includes a stand 1, a liquid storage tank 2, a base frame 13, a support 3, a cylinder 4, a tree-shaped frame 5, an extrusion block 6, a support column 7, a cooling cylinder 9, a motor 8, and a magnet 10. The four stands 1 are symmetrically arranged, and the liquid storage tank 2 is fixedly connected between them. The bottom of the liquid storage tank 2 is rotatably connected to the base frame 13. The support 3 is fixedly connected to the rear side of the liquid storage tank 2. A cylinder 4 is fixedly installed on the upper part of the support 3, and the cylinder 4 is perpendicular to the top of the liquid storage tank 2. The telescopic rod of the cylinder 4 is connected to the tree-shaped frame 5, and the bottom of the tree-shaped frame 5 is symmetrically fixed with... Two extrusion blocks 6 are connected to a support column 7 through the middle of the bottom frame 13. Two cooling cylinders 9 are also symmetrically connected to the bottom frame 13. The four cooling cylinders 9 are distributed circumferentially outside the support column 7 and are located inside the liquid storage tank 2 and perpendicular to the extrusion block 6 above. A motor 8 is fixedly installed on the top of the support column 7. The output shaft of the motor 8 is connected to the four cooling cylinders 9 respectively. Magnets 10 are fixedly connected to the outer side of the cooling cylinder 9 and the inner side of the liquid storage tank 2 on the side that are close to each other. The cooling cylinders 9 and the liquid storage tank 2 are both made of corrosion-resistant material.

[0020] like Figure 3 and Figure 4 As shown, it also includes a hinge 12, a torsion spring 1201 and an opening and closing plate 11. Two hinges 12 are symmetrically fixed to the inner side wall of the bottom frame 13. The hinge 12 is divided into two parts, which are connected by a torsion spring 1201. The other end of the hinge 12 is fixed to an opening and closing plate 11, which is located at the bottom of the cooling cylinder 9.

[0021] like Figure 3 and Figure 5 As shown, it also includes a sliding frame 14, a spring 17, a slider 16 and a limiting block 15. The sliding frame 14 is symmetrically fixed to the lower part of the outer side wall of the liquid storage tank 2. A spring 17 is provided in the sliding frame 14 near the side of the liquid storage tank 2. The other end of the spring 17 is connected to the slider 16, and the slider 16 is slidably disposed in the sliding frame 14. The other end of the slider 16 is fixed to the limiting block 15. The limiting block 15 is located at the bottom of the liquid storage tank 2 and at the bottom of the opening and closing plate 11.

[0022] like Figure 2 and Figure 5 As shown, it also includes a transmission block 18 and a propulsion block 19. The transmission block 18 is fixedly connected to the rear side of the tree frame 5. The transmission block 18 passes through the middle of the support 3 and extends downward. The other end of the transmission block 18 is fixedly connected to the propulsion block 19, which is located between the tops of the two limit blocks 15.

[0023] like Figures 1-3 As shown, it also includes a controller 20. The controller 20 is installed in the middle of the front side of the liquid storage tank 2. The controller 20 is electrically connected to the cylinder 4 and the motor 8.

[0024] When workers need to cool the produced PE pipes, they first pour coolant into the storage tank 2, then pour the molten PE pipe material into the four cooling cylinders 9, and prepare containers below the storage tank 2. Then, they start the motor 8, whose output shaft drives the four cooling cylinders 9, the base frame 13, the hinge 12, and the opening and closing plate 11 to rotate. During rotation, the surface of the cooling cylinder 9 continuously contacts the coolant, and the opening and closing plate 11 remains against the top of the two limit blocks 15. The solidification speed of the molten PE pipe material inside the cooling cylinder 9 increases as it rotates. After the PE pipe has solidified in the cooling cylinder 9, the motor 8 is turned off, and it stops rotating. When the cooling cylinder 9 runs out of power, it is attracted by the magnet 10 on the inner wall of the storage tank 2 and returns to directly below the extrusion block 6. At this time, the cylinder 4 is activated, and its extension rod extends, driving the tree-shaped frame 5, the extrusion block 6, the transmission block 18, and the propulsion block 19 to descend. During the descent, the propulsion block 19 pushes the two limit blocks 15 towards... When the two ends of the tube are pushed apart, the two push blocks 19 drive their respective connected sliders 16 to move within the slide frame 14. During this movement, the spring 17 is stretched, and at this time, the opening and closing plate 11 is not blocked by the limiting block 15. Then, the pressing block 6 extends into the cooling cylinder 9 and presses the solidified PE tube. Then, the opening and closing plate 11 is pushed open by the PE tube. When it is pushed open, the torsion spring 1201 deforms and causes the hinge 12 to rotate. At this time, the PE tube falls vertically into the container. When the PE tube has completely fallen into the container, the torsion spring 1201... 01 Deformation occurs again to reset, and the hinge 12 is rotated to return to the bottom of the cooling cylinder 9. Finally, the cylinder 4 is activated, the cylinder 4 telescopic rod retracts and drives the tree-shaped frame 5, the extrusion block 6, the transmission block 18 and the push block 19 to move upward and reset. At this time, the limit block 15 is not affected by the push block 19. The spring 17 resets and retracts, and drives the slider 16 and the limit block 15 to reset. Finally, the limit block 15 is pressed against the bottom of the opening and closing plate 11 again. At this time, the cooling of the PE pipe is completed.
