Description

Technical Field

[0001] This utility model relates to the field of power pipe cooling, specifically a cooling mechanism for a power pipe extrusion device. Background Technology

[0002] Power conduits are products made by hot-dip plastic coating of PE (modified polyethylene) or internal and external coating of epoxy resin. They have excellent corrosion resistance and excellent electrical insulation, making them suitable for high and low voltage cable wiring. During the production process, power conduits undergo an extrusion molding process. The extruded power conduits are at a high temperature and require cooling to ensure shape stability. Existing power conduit extruders use cooling devices where the extruder nozzle is aligned with the cooling device's mold. The formed power conduit enters the cooling chamber, where it is typically cooled by water. Water cooling usually involves spraying water from nozzles. However, the power conduit cannot rotate during extrusion, and the nozzle position is generally fixed. This makes it difficult to spray water evenly onto the power conduit. To solve this problem, a large number of nozzles are usually installed to spray water onto different parts of the power conduit. However, this results in many overlapping spray areas, consuming a large amount of cooling water. Therefore, we propose a cooling mechanism for power conduit extrusion devices. Utility Model Content

The gear 7 is driven to rotate back and forth by a drive assembly 5, and cooling water is injected into the inner cavity of the hollow water column 3 by a water pumping assembly 6.

[0020] The drive assembly 5 includes a servo motor 501. The drive end of the servo motor 501 is fixedly connected to a circular plate 502. The bottom of the circular plate 502 is rotatably connected to a connecting plate 503. The connecting plate 503 is rotatably connected to a connecting plate 504. The connecting plate 504 is rotatably connected to a rack 505. The rack 505 meshes with a gear 7. An elliptical guide rod 506 slides through the inner side of the rack 505. Both ends of the elliptical guide rod 506 are fixedly connected to the inner wall of the cooling box 1. In use, starting the servo motor 501 will drive the circular plate 502 to rotate. The rotation of the circular plate 502, under the action of the connecting plate 503 and the connecting plate 504, will drive the rack 505 to move back and forth along the elliptical guide rod 506. The back and forth movement of the rack 505 will drive the gear 7 to rotate back and forth.

[0021] The water pumping assembly 6 includes a water pump 601. The outlet end of the water pump 601 is connected to one end of an outlet pipe 602. The other end of the outlet pipe 602 is connected to one end of a spring tube 603. The other end of the spring tube 603 is connected to the inner cavity of the hollow water column 3. The inlet end of the water pump 601 is connected to one end of a pumping pipe 604. The other end of the pumping pipe 604 is connected to the inner cavity of the cooling tank 1. In use, when the water pump 601 is started, the cooling water in the cooling tank 1 will enter the inner cavity of the hollow water column 3 along the pumping pipe 604, the water pump 601, the outlet pipe 602, and the spring tube 603.

[0022] The water pump 601 is fixedly installed on the top of the mounting bracket 8, the mounting bracket 8 is fixedly installed on the top of the cooling box 1, and the servo motor 501 is fixedly installed on the mounting bracket 8, thus making the device installation structure stable.

[0023] A sliding box 9 is slidably installed inside the cooling box 1, and a filter cloth 10 is fixedly installed inside the sliding box 9. During the cooling process, the dripping water will fall into the sliding box 9 and be filtered and recycled through the filter cloth 10. After use, the sliding box 9 can be slid out to clean the filtered impurities.

[0024] One end of the cooling box 1 is connected to the mold tube 11, and the other end of the cooling box 1 is connected to the discharge port 12. Multiple sets of auxiliary rollers 13 are rotatably installed on the inner wall of the cooling box 1 through sealed bearings.

The cooling water in the cooling box 1 enters the inner cavity of the hollow water column 3 along the water suction pipe 604, the water pump 601, the water outlet pipe 602, and the spring tube 603. The cooling water in the hollow water column 3 is sprayed out from the nozzle 4 and sprayed onto the power tube to cool it.

[0027] During the cooling process, starting the servo motor 501 will drive the circular plate 502 to rotate. The rotation of the circular plate 502, under the action of connecting plate 1 503 and connecting plate 2 504, will drive the rack 505 to move back and forth along the elliptical guide rod 506. The back and forth movement of the rack 505 will drive the gear 7 to rotate back and forth. The back and forth rotation of the gear 7 will drive the hollow water column 3 to rotate back and forth, which will in turn drive multiple sets of nozzles 4 to rotate back and forth around the power tube and spray water, thereby uniformly cooling the power tube.
