Description

Technical Field

[0001] This utility model relates to the field of PE pipe processing technology, specifically a PE pipe sizing sleeve assembly. Background Technology

[0002] The sizing sleeve (also known as the sizing device or sizing ring) in the production of PE (polyethylene) pipes is a key component in the extrusion molding process, mainly used to ensure the accuracy of the outer diameter and surface quality of the pipe.

[0003] However, to ensure the processing quality of PE pipes, cooling pipes are installed inside the sizing sleeve of the PE pipe to enhance the cooling effect. At this time, the cooling pipes are set up to provide a channel for the flow of cooling water within the sizing sleeve of the PE pipe. During the flow of cooling water, impurities will also be carried into the interior of the cooling pipes. After the impurities enter the interior of the cooling pipes with the flow of water, they are very easy to fall into the interior of the cooling pipes under the action of gravity. As the number of times the cooling pipes are used increases, the amount of impurities accumulated in the cooling pipes will also increase, and may even cause the cooling pipes to be blocked by impurities, thereby affecting the normal use of the cooling pipes. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a PE pipe sizing sleeve assembly, which has the advantages of improving the cooling effect of the sizing sleeve, preventing impurities in the water from clogging the nozzle, and ensuring the cooling effect of the cooling water, thus solving the problems mentioned in the background art.

[0029] Working principle: In use, first, turn on the power to the water pump 4. After the water pump 4 is turned on, it drives the flow of water inside the cooling water tank 6. The water in the cooling water tank 6 enters the transition pipe 5. The water in the transition pipe 5 first passes through the primary filter screen 8 and then enters the secondary filter screen 9 for further filtration. The filtered water then flows from the inlet pipe 15 through the water pump 4 into the main pipe 13. The water in the main pipe 13 flows into the outlet pipe 12 and the branch pipe 20. The water in the branch pipe 20 enters the horizontal pipe 19 and then is sprayed from the nozzle 7 to the cooling pipe 3. The water inside the outer pipe 2 flows from the connecting... Water flows back into the cooling water tank 6 through pipe 17. Then, water from the main pipe 13 enters the outer pipe 2 and then enters the cooling water tank 6 through the inlet pipe 11, allowing the water in the cooling water tank 6 to be recycled. Finally, when it is necessary to clean the impurities generated after filtration in the transition pipe 5, the fastening bolt 24 is rotated out from the inside of the upper clamp 101 and the lower clamp 102. At this time, the upper clamp 101 and the lower clamp 102 can be removed from the transition pipe 5, and the transition pipe 5 can be taken out from between the water guide pipe 18 and the water inlet pipe 15, so that the transition pipe 5 can be replaced, thereby preventing impurities from clogging the nozzle 7.
