Description

Technical Field

[0001] The utility model specifically relates to the technical field of pipe production cooling, in particular to a cooling device for producing PE pipes. Background Art

[0002] The production process of PE pipe is generally divided into several steps, including raw material preparation, extrusion molding, cooling and shaping, cutting and inspection. In the cooling and shaping process, the PE pipe after extrusion will pass through the cooling system to quickly reduce the surface temperature of the pipe to keep it in a solid state. It is usually cooled by water cooling or air cooling.

[0003] The water cooling methods in the prior art are divided into complete immersion cooling and spray cooling water. However, the complete immersion cooling water has a large water resource loss, and the cooling water after use is not easy to be recycled, which easily leads to poor water quality of the cooling water, thereby affecting the cooling effect of the PE pipe. The spray cooling method is more widely used.

[0004] However, in one of the spray cooling methods in the prior art, the spray direction is always relatively fixed, and uneven cooling may occur in some areas of the surface of the PE pipe during cooling. In another method, the spray direction remains unchanged, and the PE pipe is driven by an external force to make a circular motion. In this case, the PE pipe just extruded is soft, so it is very easy to be damaged when it moves in a circular motion, thereby affecting the quality of the final PE pipe production. At the same time, after the nozzle in the spray method in the prior art is used for a long time, the cooling water contains impurities due to incomplete purification of the cooling water, so the nozzle is blocked when it is used, which leads to the inability of some nozzles to effectively spray cooling water during water spraying, which also causes uneven cooling.

[0005] In view of this, the utility model provides a cooling device for producing PE pipes to make up for and improve the deficiencies of the prior art. Utility Model Content

[0012] Furthermore, the guide component is threadedly connected to the upper surface of the filter plate through an adjustable frame, and the adjustable frame is an adjustable telescopic structure, and the adjustable frame can achieve height adjustment in the vertical direction.

[0013] Furthermore, the intermittent turbulence processing mechanism includes a servo motor fixedly installed on the horizontal plane of the upper end of the cooling box, the output shaft end of the servo motor is coaxially fixedly connected with the intermittent disk, and an inverted concave support plate is arranged below the intermittent disk, the lower end of the inverted concave support plate is slidably connected to the cooling box, an outer wall of one side of the inverted concave support plate is fixedly connected with an elastic member, the elastic member is specifically implemented as a spring, and one end of the spring is fixedly connected to the outer wall of the cooling box, and the other end of the spring is fixedly connected to the outer wall of the inverted concave support plate, and the lower end of the inverted concave support plate is fixedly connected with a combined support plate, and the combined support plates are evenly arranged with no less than six, and the six combined support plates are parallel to each other, and the outer walls of the six combined support plates are annularly and evenly fixedly connected with a connecting frame, and the outer wall of the connecting frame is evenly fixedly connected with a processing disk, the processing disks all correspond to each other, and the upper end surface of the processing disk close to the nozzle is snap-connected with the processing head, and the inner surface of the center ring close to each other is evenly fixedly connected with a limiting plate, and multiple combined support plates are slidably connected to the limiting plate.

[0014] Furthermore, the outer ring surface of the intermittent disk is evenly provided with partial teeth, and the center of the upper end surface of the inverted concave support plate is provided with convex teeth, and the intermittent disk is meshed with the convex teeth on the upper end surface of the inverted concave support plate through the partial teeth on its outer ring surface.

[0019] The cooling device for producing PE pipes can reduce the pressure of the cooling water when the nozzle sprays cooling water, which is blocked and intercepted by the processing disk, so as to avoid the damage to the surface of the PE pipe caused by excessive pressure when the cooling water is sprayed out. At the same time, the processing head can be reciprocated horizontally intermittently against the bottom surface of the nozzle, so as to automatically scrape off impurities adhering to the bottom surface of the nozzle, so as to avoid the blockage of the nozzle due to impurities in the cooling water over time. The intermittent reciprocating horizontal displacement of the processing head can ensure that the nozzle has a good water output effect every time the water is sprayed for cooling, so as to improve the comprehensive cooling effect of the water spray cooling of the PE pipe.

The outer wall of the concave support plate 23 is fixedly connected, and the lower end of the inverted concave support plate 23 is fixedly connected with a combined support plate 25. The combined support plates 25 are evenly arranged with no less than six, and the six combined support plates 25 are parallel to each other. The outer walls of the six combined support plates 25 are annular and evenly fixedly connected with a connecting frame 26. The outer wall of the connecting frame 26 is evenly fixedly connected with a processing disk 27. The processing disks 27 correspond to the nozzles 18, and the upper end surface of the processing disk 27 close to the nozzle 18 is snap-connected with a processing head 28.

[0040] The inner surface of the central ring 1101 on one side close to each other is evenly fixedly connected to the limit plate 29, and the plurality of combined support plates 25 are all slidably connected to the limit plate 29;

[0041] Specifically, the outer ring surface of the intermittent disk 22 is evenly provided with partial teeth, and the center of the upper end surface of the inverted concave support plate 23 is provided with convex teeth, and the intermittent disk 22 is meshed with the convex teeth on the upper end surface of the inverted concave support plate 23 through the partial teeth on its outer ring surface;

[0042] Specifically, the processing head 28 is a plastic brush, and the plastic brush is distributed in a rectangular shape as a whole, and the upper end surface of the processing head 28 is attached to the lower end surface of the nozzle 18;

[0043] The power water pump 13 and the servo motor 21 are both controllably connected to the controller.

[0044] The complete usage steps and working principle of the above embodiment are as follows:

[0045] Initial definition: When the guide component 19 in this scheme is used, if a large-sized PE pipe is encountered, the guide component 19 of matching size and specification is selected according to the diameter of the PE pipe to be cooled. In specific operation, since the guide component 19 is threadedly connected to the upper surface of the filter plate 1103 through the adjustable frame 1901, and the adjustable frame 1901 is an adjustable telescopic structure, the staff can disassemble the guide component 19 and the adjustable frame 1901 for replacement;

[0046] When in use, the staff starts the power water pump 13 through the controller, and uses the power water pump 13 to pump the cooling water in the water tank 12 through the main pipe body 14 and the branch pipe body 15 and the water delivery ring pipe 16 and the water delivery array pipe 17, and finally sprays it out evenly from the nozzle 18, thereby ensuring that the interior of the cooling box 11 is in a relatively wet and cold state in advance;

[0047] Then, the staff, with the help of the external traction device, gradually feeds the extruded PE tube into the interior of the cooling box 11. During the process, it is necessary to ensure that the center of the PE tube corresponds to the center of the center ring 1101. As the PE tube is fed into the interior of the cooling box 11, the PE tube will contact the outer wall of the guide component 19. Since the guide component 19 can rotate and the outer surface of the guide component 19 is a smooth surface, the guide component 19 can not only ensure the stability of the PE tube during cooling in the cooling box 11, but also reduce the scratches on the outer wall of the PE tube during the transmission process, thereby ensuring the surface quality of the PE tube after forming.

[0048] Thus, after the PE pipe is sent into the cooling box 11, the cooling water is evenly sprayed on the entire outer ring surface of the PE pipe by using the nozzles 18 which are evenly arranged and distributed in a circular shape, so that the cooling water contacts the outer wall of the PE pipe, thereby realizing the cooling treatment. Compared with the single horizontal water spray cooling method in the prior art, it is easy to cause incomplete cooling of the local area of ​​the surface of the PE pipe, and the impact force of the large flow rate of water spray in one direction will cause dents to the incompletely cooled PE pipe. In this scheme, the water spray method is changed to an annular water spray method, so as to maximize the uniform contact between the cooling water and the outer wall of the PE pipe, and at the same time disperse the flow rate sprayed in one direction to reduce the impact force, thereby achieving an effective cooling effect to ensure the surface quality of the PE pipe after forming.

[0049] At the same time as the above-mentioned cooling and temperature reduction, as the nozzle 18 sprays water for cooling, the staff simultaneously starts the servo motor 21 by control, and controls the output shaft of the servo motor 21 to keep rotating at a low speed. When the intermittent disk 22 is driven by the servo motor 21 to rotate at a low speed, the intermittent disk 22 will be driven to rotate synchronously. Since the outer ring surface of the intermittent disk 22 is evenly provided with partial teeth, and a convex tooth is provided at the center of the upper end surface of the inverted concave support plate 23, and the intermittent disk 22 is meshed with the convex teeth on the upper end surface of the inverted concave support plate 23 through the partial teeth of its outer ring surface, as the intermittent disk 22 rotates, as the partial teeth are meshed with the convex teeth, the intermittent disk 22 will drive the inverted concave support plate 23 to slide along the groove between it and the cooling box 11, which can be specifically described as follows Figure 5 As shown, the elastic member 24 is in a compressed state during the process, and as the intermittent disk 22 continues to rotate, some teeth are not engaged with the convex teeth, and the inverted concave support plate 23 will slide back and forth under the elastic force of the elastic member 24, so that the inverted concave support plate 23 and the combined support plate 25 can perform intermittent reciprocating horizontal displacement movement;

[0050] In the above process, the inverted concave support plate 23 will synchronously drive the combined support plate 25 to move on the limit plate 29 during the sliding displacement and sliding reset process, and the combined support plate 25 will drive the connecting frame 26, the processing disc 27 and the processing head 28 to move after the synchronous movement. Since the surface of the connecting frame 26 is evenly fixedly connected with the processing disc 27, and the upper end surface of the processing disc 27 is snap-connected with the processing head 28, and the processing head 28 is a plastic brush, and the upper end surface of the processing head 28 is in contact with the bottom surface of the nozzle 18, as the connecting frame 26 is horizontally displaced, the processing disc 27 and the processing head 28 will be driven to move synchronously;

[0051] Since the processing disk 27 is hollow as a whole, when the nozzle 18 sprays cooling water, if the pressure of the sprayed water is too high, the blocking and intercepting effect of the processing disk 27 will cause the pressure of the sprayed cooling water to be reduced, thereby avoiding the damage to the surface of the PE pipe caused by excessive pressure when the cooling water is sprayed. At the same time, with the help of the intermittent reciprocating horizontal displacement of the processing head 28 against the bottom surface of the nozzle 18, impurities adhered to the bottom surface of the nozzle 18 can be automatically scraped off to avoid the blockage of the nozzle 18 due to impurities in the cooling water over time. With the help of the intermittent reciprocating horizontal displacement of the processing head 28, it can be ensured that the nozzle 18 has a good water output effect every time the water is sprayed for cooling, thereby improving the comprehensive cooling effect of the water spray cooling on the PE pipe.
