Description

Technical Field

[0001] The invention relates to the technical field of PVC-U pipes, in particular to a PVC-U low-density composite reinforced pipe and cooling equipment. Background Art

[0002] PVC-U pipe is made of sanitary polyvinyl chloride (PVC) resin as the main raw material, with appropriate amount of stabilizer, lubricant, filler, color enhancer, etc., extruded by plastic extruder and injection molded by injection molding machine, and completed through cooling, curing, shaping, inspection, packaging and other processes to produce pipes and pipe fittings;

[0003] However, in the prior art, after the PVC-U pipe is exposed to light for a long time, the main body of the pipe is prone to material aging, which can easily affect the strength and pressure resistance of the main body of the pipe, and the overall flame retardant effect is poor;

[0004] When PVC-U pipes are extruded during production, the extruded pipes need to be cooled. However, existing equipment only adds a water spray pipe on the upper side of the cooling trough, and sprays cooling water on the pipe surface at a fixed angle.

After cooling, there is a blank area between the subsequent pipe processing equipment and the cooling structure.

[0034] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0035] Example

[0036] See also Figure 1-10 , a PVC-U low-density composite reinforced pipe, comprising, by mass percentage, 60% of PVC resin, 3% of calcium zinc stabilizer, 20% of light calcium carbonate, 2% of acrylic ester impact modifier, 5% of chlorinated polyvinyl chloride, 1% of glycerol monostearate, 0.5% of bisphenol A antioxidant, 0.5% of zinc oxide, 1% of dioctyl phthalate, 5% of hydroxide flame retardant and 1% of glass fiber;

[0037] In the specific implementation process, most of the existing PVC-U pipes are made of PVC resin, calcium zinc stabilizer, light calcium carbonate and chlorinated polyvinyl chloride as the main components. However, as the PVC-U pipe is exposed to light for a long time and for a long time, the main body of the pipe is prone to material aging, which is easy to affect the strength and compressive resistance of the main body of the pipe. At the same time, the overall flame retardant effect is poor. Based on this, this case preferably adds bisphenol A antioxidant to protect the PVC resin from oxidation and extend the service life of the pipeline. Zinc oxide is added as a UV shielding agent, which has good anti- It can improve the ability to radiate and scatter ultraviolet rays, and at the same time improve the heat resistance and weather resistance of the material. Secondly, the addition of dioctyl phthalate plasticizer can increase the flexibility, plasticity and processing performance of PVC materials, and further increase the hydroxide flame retardant to give the pipeline flame retardant properties and improve safety. Finally, a small amount of glass fiber is added to significantly improve the strength and pressure resistance of the pipeline while maintaining good flexibility. After adding the above materials, the overall performance and service life of the pipeline can be increased, while the pipeline's antioxidant property, light stability, flame retardant effect and strength and pressure resistance are increased respectively.

A spline 27 is arranged on one side of the first driven teeth 26. A columnar bin 28 is arranged on the inner side of the second gear ring 23. An annular plate 29 is sleeved on the outer side of the columnar bin 28. One side of the annular plate 29 is connected to the wall of one side of the cooling bin 1 through an electric push rod 30. A winding roller 31 is rotatably connected to one side of the annular plate 29. A spline sleeve 32 corresponding to the spline 27 is arranged on one side of the winding roller 31. A guide assembly is rotatably connected inside the columnar bin 28. A rope 33 is connected to the upper side of the guide assembly. The upper side of the rope 33 passes through the wall of the columnar bin 28 and is connected to the winding roller 31. One side of the guide assembly is connected to the inner wall of the columnar bin 28 through a spring 34.

[0043] The guide assembly includes a rotating frame 35 rotatably connected to the inner wall of the columnar bin 28, a guide wheel 36 with a recessed middle portion is rotatably connected to the lower side of the rotating frame 35, a second driven tooth 37 is arranged on one side of the guide wheel 36, a third driving member 38 is arranged on one side of the rotating frame 35, a third driving tooth 39 is connected to the driving end of the third driving member 38, and the lower side of the third driving tooth 39 passes through the lower side of the rotating frame 35 and meshes with the second driven tooth 37;

[0044] It should be noted that after the PVC-U pipe is extruded, the pipe needs to be cooled. In the prior art, in most cases, a single water pipe is added to the upper side of the PVC-U pipe cooling trough, and an opening is made at the lower side of the water pipe to allow cooling water to fall on the PVC-U pipe for cooling. However, this method results in uneven cooling and low overall efficiency. It is easy for the pipe to be cooled unevenly as a whole, which will lead to uneven overall temperature after the pipe is discharged from the cooling trough. This may easily lead to slight deformation of the pipe as a whole, affecting the overall production quality of the pipe. For this reason, during the operation of the present case, one side of the pipeline enters the interior of the cooling bin 1 through a through hole on one side of the cooling bin 1, and passes through the middle part of the annular rotating seat 19. At this time, the suction pump 5 is running, and cooling water is extracted from the storage tank 4 through the cross pipe 6, and The cooling water is fed into the annular outer tube 9 through the delivery pipe 7, and then enters the cavity 12 of the inner wall of the inner tube 11 through the openings 13 on the upper and lower sides of the inner tube 11, and further enters the hollow tube 16, and finally sprayed out through a circle of nozzles 18 on the inner side of the annular tube 17. The support seat 10 is used to provide vertical support force for the annular outer tube 9. At the same time, the first driving member 20 operates, cooperates with the first gear ring 22 and the first rotating gear, and drives the inner tube 11, the first flange 14, the second flange 15, the multiple hollow tubes 16, the multiple annular tubes 17, the multiple nozzles 18 and the annular rotating seat 19 to perform concentric rotation operations, so that the PVC-U pipe extending into the cooling bin 1 can be evenly and rotatingly sprayed with cooling water, so that the PVC-U pipe can be efficiently cooled;

[0045] In the above operation process, after the PVC-U pipe enters the cooling chamber 1, the present invention can complete the coaxially rotating annular cooling water spraying operation on the PVC-U pipe through the cooperation of multiple groups of components. Compared with the simple cooling device in the prior art, the present invention has uniform cooling as a whole, thereby preventing the PVC-U pipe from being deformed due to uneven cooling during the cooling process.

[0046] After the cooling operation is completed, the PVC-U pipe extends from the through hole on the other side of the cooling bin 1 into the columnar bin 28. Before that, the second driving member 24 operates, cooperates with the second active tooth 25 to drive the gear ring to rotate, and drives the spline 27 and the spline sleeve 32 plugged with the spline 27 to rotate through the first driven tooth 26, thereby driving the winding roller 31 to rotate and winding the rope 33, thereby driving the rotating frame 35 to rise and stretching the spring 34. After the PVC-U pipe extends out of the guide hole of the columnar bin 28, the electric push rod 30 operates and pushes the annular plate 29 to move the columnar bin 28, and then the spline sleeve 32 separates from the spline 27. The spring 34 will pull the guide wheel 36 on the lower side of the rotating frame 35 to fit tightly against the surface of the PVC-U pipe, and at the same time, the winding roller 31 will be pulled through the rope 33 to perform an automatic unwinding operation;

[0047] At the same time, the third driving member 38 operates, cooperates with the third active tooth 39 and the second driven tooth 37, and can drive the guide wheel 36 to rotate, thereby assisting the PVC-U pipe to move, and can realize the guiding and pulling operation of the PVC-U pipe, to prevent the pipe from being deformed under the action of gravity after cooling, and facilitate the subsequent processing operation of the PVC-U pipe;

[0048] When guiding and pulling operations are performed on pipes of different specifications, the electric push rod 30 contracts and drives the spline 27 groove to reconnect with the spline 27 through the annular plate 29. Since there may be misalignment between the two, a circle of inclined surface is opened on one side of the spline sleeve 32. As the annular plate 29 moves, the spline sleeve 32 and the winding roller 31 will rotate in a small range, so that the spline sleeve 32 and the spline 27 can be smoothly plugged in. Then the above operation is repeated in reverse, the rotating frame 35 can be stretched and reset, and the pulling and guiding operations can be performed on pipes of different diameters subsequently.

[0049] Exhaust racks 40 are provided on both sides of the upper side of the partition 8, and exhaust pipes 41 are evenly connected to the lower side of the exhaust racks 40. The lower side of the exhaust pipes 41 penetrates the partition 8, and the two exhaust racks 40 are connected through pipelines. A fan 42 is provided on one side of the upper cover 2, and the fan 42 is connected to the exhaust rack 40 through a pipeline. The lower side of the exhaust pipe 41 is set to be inclined. When the pipe is efficiently cooled, the fan 42 runs, and high-pressure gas is introduced into the exhaust rack 40 and discharged through the exhaust pipe 41. The lower side of the exhaust pipe 41 is set to be inclined, and the inclination direction is toward the center of the pipe. While the pipe is cooled, the high-pressure gas can be blown toward the pipe, thereby further increasing the cooling effect of the pipe.

[0050] Support blocks 43 are provided on both sides of the upper side of the storage tank 4. A filter plate 44 is connected to the upper side of the support block 43 by bolts, which can filter the cooling water. A movable plate is provided on the front side of the cooling bin 1. After the device has been running for a period of time, the movable plate can be removed and the filter plate 44 can be cleaned.

[0051] Sealing rings 45 are sleeved on both sides of the inner tube 11 , and the outer side of the sealing ring 45 is rotatably connected to the inner wall of the annular outer tube 9 , so as to increase the sealing performance between the annular outer tube 9 and the inner tube 11 .

[0052] The upper and lower sides of the annular plate 29 are slidably connected to the inner walls of the upper and lower sides of the protective cover 3 to increase the stability of the movement of the annular plate 29;

[0053] The technical solution adds a rotatable cooling structure inside the cooling bin 1, and performs uniform and efficient cooling operations on the pipe after the pipe is extruded to prevent the pipe from being deformed due to uneven cooling. At the same time, a guiding and traction structure is added on one side of the cooling bin 1. After the cooling of the PVC-U pipe is completed, the pipe is guided and limited to ensure the normal transportation of the pipe. At the same time, the structure is simple, which reduces the manufacturing difficulty and processing cost of the guiding and traction part, and facilitates the subsequent processing operations of the pipe.
