Description

Technical Field

[0001] This utility model relates to the field of cable processing, and in particular to a cooling device for cable insulation extrusion. Background Technology

[0002] According to the patent document with publication number CN222335695U, water overflows from the water tank to the water collection chambers at both ends, and the water is pushed into the water tank by a circulation pump to accelerate the water flow. Then, a vortex air pump is used to transport nitrogen gas from the liquid nitrogen bottle to the aeration pipe at the bottom of the tank at a certain flow rate through the gas delivery pipe. The liquid nitrogen is used to cool the water and the diffused bubbles can also agitate the water to a certain extent.

[0003] The patent document states that when cooling water with liquid nitrogen, the cost of the liquid nitrogen is relatively high, which is very uneconomical. The high cost also means that because the temperature of liquid nitrogen is relatively low, even when it diffuses into the water in the form of bubbles, the temperature is still relatively low. Therefore, ice may form at the point where the bubbles overflow, affecting the subsequent overflow of bubbles. In addition, at the point where the cable insulation layer is just squeezed out and has not yet entered the water, the insulation layer may be soft and unable to cool quickly, making it prone to deformation and affecting the subsequent cooling and solidification effect of the cable insulation layer.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1-8 As shown, a cooling device for cable insulation extrusion includes a water tank 5, a plurality of limiting mechanisms 1 on the upper side of the water tank 5, a circulation mechanism 4 on the lower side of the water tank 5, a cooling mechanism 3 at the water outlet end of the circulation mechanism 4, and a support mechanism 2 located inside the water tank 5.

[0031] In this embodiment: the support mechanism 2 includes multiple support rollers 21, each support roller 21 has three water-dispensing plates 22 fixed on its front and rear sides, and each support roller 21 has a rotary joint 23 on its front and rear sides. A water inlet pipe 24 is provided on the front side of the water tank 5, and a water outlet pipe 25 is provided on the rear side of the water tank 5. An annular spray frame 26 is fixedly installed at one end of the water outlet pipe 25, and the annular spray frame 26 is fixed to one end of the water tank 5. A conical surface is opened at the other end of the annular spray frame 26, and multiple nozzles for cooling the freshly extruded insulation are fixed on the conical surface. Each support roller 21 is rotatably connected to the inside of the water tank 5 at both its front and rear ends. Both the support rollers 21 and the annular spray frame 26 are hollow. Branch pipes for supplying water to the rotary joint 23 are provided on both the water inlet pipe 24 and the water outlet pipe 25. Multiple nozzles on the annular spray frame 26... The heads are arranged in a ring around the cable. The winding of the cable drives multiple support rollers 21 inside the water tank 5 to rotate synchronously. The rotation of the support rollers 21 agitates the water in the water tank 5 through the water-dispersing plates 22 on both sides, thereby making the water temperature in the water tank 5 uniform. In addition, the cooled water is sent into the hollow support rollers 21 through the water inlet pipe 24 and the rotary joint 23 on the front side of the water tank 5. At this time, the support rollers 21 cool the water in the vicinity. At the same time, the water in the support rollers 21 enters the water outlet pipe 25 through the rotary joint 23 on the rear side of the water tank 5, and is sent into the annular spray frame 26 through the water outlet pipe 25. Then, the water is sprayed onto the outside of the newly extruded cable insulation layer through multiple nozzles on the annular spray frame 26, thereby preventing the newly extruded insulation layer from deforming.

[0032] In this embodiment: the limiting mechanism 1 includes a limiting frame 11, a limiting seat 12 is slidably connected to the inner side of the limiting frame 11, and a limiting wheel 13 for pressing on the upper side of the cable is rotatably connected to the lower end of the limiting seat 12. The top of the limiting seat 12 is provided with a spring for abutting against the inner top side of the limiting frame 11. The spring pushes the limiting seat 12 to move downward along the limiting frame 11, so that the limiting wheel 13 presses the cable on the upper side of the support roller 21.

[0033] In this embodiment: the circulation mechanism 4 includes a water suction tank 41, which is fixed at one end of the bottom of the water tank 5. A cooling water tank 43 is fixed at the middle of the bottom of the water tank 5. A heat dissipation grid 45 is fixed at the bottom of the cooling water tank 43. A plurality of semiconductor cooling chips 44 are provided between the heat dissipation grid 45 and the cooling water tank 43. A fan 46 is fixed on the lower side of the heat dissipation grid 45. A circulating water pump 42 is provided between the water suction tank 41 and the cooling water tank 43. A filter screen is provided inside the water suction tank 41. The water inlet and outlet of the circulating water pump 42 are connected to the cooling water tank 43 through... The cooling water tank 43 is connected by a hose, and a water guide pipe is provided on the other side of the cooling water tank 43 for sending water to the other end of the water tank 5. The water in the suction tank 41 is pumped to the cooling water tank 43 by the circulating water pump 42. At this time, the filter screen plate on the upper side of the suction tank 41 will filter the water in one end of the water tank 5, while the semiconductor cooling chip 44 begins to cool the water in the cooling water tank 43. At the same time, the fan 46 dissipates heat from the semiconductor cooling chip 44 through the heat dissipation grid plate 45. In addition, the water in the cooling water tank 43 is sent to the other side of the water tank 5 through the water guide pipe, thereby realizing the circulation and cooling of the water in the water tank 5.

[0034] In this embodiment: the cooling mechanism 3 includes a water supply pump 31, which is fixed on the other side of the cooling water tank 43. The outlet of the water supply pump 31 is provided with a water delivery pipe 32. The end of the water delivery pipe 32 away from the water supply pump 31 is provided with an air-cooled radiator 33. The outlet of the air-cooled radiator 33 is connected to the inlet pipe 24. The inlet of the water supply pump 31 is provided with a bent pipe connected to the cooling water tank 43. The water supply pump 31 pumps the water in the suction tank 41 into the water delivery pipe 32, and then sends it into the air-cooled radiator 33. The air-cooled radiator 33 further reduces the temperature of the water. The water that has been cooled twice flows into the inlet pipe 24 and cools the support roller 21 through the inlet pipe 24, thereby accelerating the cooling speed of the entire cable insulation layer.

[0035] Working principle: In use, the insulation layer is first extruded and wrapped around the outside of the cable using an extrusion device. The cable then passes between multiple support rollers 21 and limit wheels 13. Simultaneously, a spring pushes the limit seat 12 downwards along the limit frame 11, causing the limit wheels 13 to press the cable against the upper side of the support rollers 21. Then, as the cable moves through the water in the tank 5, it simultaneously drives the multiple support rollers 21 and limit wheels 13 to rotate in opposite directions. During this process, the rotation of the support rollers 21 agitates the water in the tank 5 through the water-dispersing plates 22 on both sides, thus ensuring a uniform water temperature within the tank 5.

[0036] In addition, the circulating water pump 42 pumps water from the suction tank 41 to the cooling tank 43. At this time, the filter screen on the upper side of the suction tank 41 filters the water at one end of the water tank 5. Simultaneously, the thermoelectric cooler 44 begins to cool the water in the cooling tank 43. Furthermore, the fan 46 dissipates heat from the thermoelectric cooler 44 through the heat dissipation grille 45. The water in the cooling tank 43 is then sent to the other side of the water tank 5 through the water pipe, thereby achieving the circulation and cooling of the water in the water tank 5. At the same time, the water supply pump 31 pumps water from the suction tank 41 to the water supply pipe 32, and then the water supply pipe 32 sends it to the air-cooled radiator 3. Inside the 3rd section, the water temperature is lowered again by the air-cooled radiator 33. The water that has been cooled twice flows into the inlet pipe 24. The cooled water is then sent through the rotary joint 23 on the front side of the water tank 5 into the hollow support roller 21. At this time, the support roller 21 cools the water in its vicinity. Meanwhile, the water in the support roller 21 enters the outlet pipe 25 through the rotary joint 23 on the rear side of the water tank 5, and is then sent into the annular spray frame 26. The multiple nozzles on the annular spray frame 26 spray water onto the outside of the newly extruded cable insulation layer, thereby preventing the newly extruded insulation layer from deforming.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
