Description

Technical Field

[0001] This utility model belongs to the field of cooling devices, and relates to a cooling device for an extrusion machine used in the production of wire sheaths. Background Technology

[0002] The cooling device of the conductor sheath extruder is a key component of the entire production line. Its core function is to rapidly, uniformly and controllably cool and solidify the plastics such as PVC, PE and PP that are extruded from the die and wrapped around the conductor and are in a high-temperature molten state, so as to ensure that the final product obtains stable geometric dimensions, excellent electrical properties, smooth surface quality and sufficient mechanical strength.

[0003] Traditional cooling devices employ a single cooling method, often using conventional spray heads or immersion cooling on one side. This results in uneven water flow distribution, low cooling efficiency, and difficulty in adapting to high-speed extrusion scenarios. Furthermore, the utilization rate of cooling water is low, and impurities easily accumulate and clog the pipes, requiring frequent shutdowns for cleaning and resulting in short maintenance cycles. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a cooling device for an extruder used in the production of wire sheaths with high cooling efficiency.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A cooling device for an extruder used in the production of conductor sheaths includes a linear cooling water tank. The linear cooling water tank has symmetrically arranged feed inlets at its left and right ends. Lateral protruding horizontal bars are symmetrically fixedly connected to both ends of the linear cooling water tank. A circulating bottom water tank is fixedly connected to the lower end of the linear cooling water tank, and a circulating pump is connected externally to the circulating bottom water tank. Multiple spray column pipes are fixedly connected to the upper ends of the lateral protruding horizontal bars, and these spray column pipes are horizontally arranged on both sides of the linear cooling water tank. Protruding lugs are symmetrically fixedly connected to both sides of the output ends of the spray column pipes. Supporting and limiting frames are fixedly connected to the lower ends of two of the protruding lugs. A spiral vortex shaft is fixedly connected to the outer end of the supporting and limiting frames. A load-bearing base plate is fixedly connected to the lower end of the circulating bottom water tank.

[0007] In the cooling device of the extruder for producing wire sheaths described above, multiple limiting inner shafts are fixedly connected to the left and right inner walls of the linear cooling water tank, and a wire roller is installed between two horizontally corresponding limiting inner shafts.

[0008] In the cooling device of the extruder for producing wire sheaths described above, the spiral vortex shaft is located directly below the liquid outlet end of the spray column pipe, and a flat bottom plate is fixedly connected to the middle of the lower inner wall of the linear cooling water tank.

[0009] In the cooling device of the extruder for producing wire sheaths described above, side guide plates are symmetrically fixedly connected to the front and rear ends of the flat base plate, and the surface of the flat base plate is provided with a plurality of filter mesh holes.

[0010] In the cooling device of the extruder for producing conductor sheaths described above, the flat bottom plate is located at the connection between the linear cooling water tank and the bottom circulating water tank, and the conductor sheath passes through the inner end of the linear cooling water tank.

[0011] In the cooling device of the extruder for producing conductor sheaths described above, the conductor sheath is wound around multiple conductor rollers, and the spiral vortex shaft is located directly above the linear cooling water tank.

[0012] In the cooling device of the extruder for producing conductor sheaths described above, the linear cooling water tank is filled with a number of cooling liquids, and the multiple spray column pipes and multiple conductor rollers are arranged in sequence at intervals.

[0013] Compared with existing technologies, the cooling device of this extruder for producing conductor sheaths uses a linear cooling water tank with an inlet that engages with the conductor roller shaft and is fixed by a limiting inner shaft to ensure stable conductor sheath conveying and avoid uneven cooling caused by deviation. Furthermore, the horizontally distributed spray columns on both sides are spaced apart from the conductor roller shaft, and combined with the swirling effect of the spiral vortex shaft, the cooling water forms a three-dimensional, enveloping cooling effect, which is more efficient than traditional single-sided spraying. The circulating pump and the bottom circulating water tank form a closed-loop system, which, together with the filter mesh holes on the flat bottom plate and the side guide plates, achieves purified and reused cooling water, resulting in high water saving rate and high impurity filtration efficiency, reducing equipment blockage and failure rates, and extending maintenance cycles.

[0022] like Figure 1 As shown in Figure 4, the cooling device of the extruder for producing the outer sheath of the conductor includes a linear cooling water tank 1. The linear cooling water tank 1 has symmetrically arranged feed inlets 11 at its left and right ends. Side-protruding horizontal bars 13 are symmetrically fixedly connected to the left and right ends of the linear cooling water tank 1. A circulating bottom water tank 3 is fixedly connected to the lower end of the linear cooling water tank 1. A circulating pump 4 (model ISG50-125) is connected to the external of the circulating bottom water tank 3. Multiple spray column pipes 5 are fixedly connected to the upper end of the side-protruding horizontal bars 13, and the multiple spray column pipes 5 are horizontally arranged on both sides of the linear cooling water tank 1. Protruding lugs 6 are symmetrically fixedly connected to both sides of the output end of the spray column pipes 5. A support limiting frame 7 is fixedly connected to the lower end of two of the protruding lugs 6. A spiral vortex shaft 14 is fixedly connected to the outer end of the support limiting frame 7. A load-bearing base plate 12 is fixedly connected to the lower end of the circulating bottom water tank 3.

[0023] Multiple limiting inner shafts 2 are fixedly connected to the left and right inner walls of the linear cooling water tank 1, and a guide roller shaft 15 is installed between two horizontally corresponding limiting inner shafts 2.

[0024] The spiral vortex shaft 14 is located directly below the liquid outlet end of the spray column pipe 5, and a flat bottom plate 9 is fixedly connected to the middle of the lower inner wall of the linear cooling water tank 1.

[0025] The front and rear ends of the flat base plate 9 are symmetrically fixedly connected with side guide inclined plates 8, and the surface of the flat base plate 9 is provided with a plurality of filter mesh holes 10.

[0026] The flat bottom plate 9 is located at the connection between the linear cooling water tank 1 and the circulating bottom water tank 3, and the inner end of the linear cooling water tank 1 is penetrated by the outer sheath of a wire.

[0027] The outer sheath of the conductor is wound around multiple conductor rollers 15, and the spiral vortex shaft 14 is located directly above the linear cooling water tank 1.

[0028] The linear cooling water tank 1 is filled with a number of cooling water liquids, and the multiple spray column pipes 5 and multiple guide rollers 15 are arranged in sequence at intervals.

[0029] In this design, the outer sheath of the conductor enters the device through the symmetrical inlet ports 11 at both ends of the linear cooling water tank 1, and is wound around the outside of multiple conductor rollers 15. The conductor rollers 15 are fixed to the left and right inner walls of the linear cooling water tank 1 by two horizontally corresponding limiting inner shafts 2, achieving stable support and conveying of the conductor sheath. After the circulating pump 4 starts, it extracts the cooling water from the circulating bottom water tank 3 connected to the lower end of the linear cooling water tank 1 and conveys it to multiple spray column pipes 5 fixed to the upper end of the side protruding horizontal bar 13. The multiple spray column pipes 5 are horizontally arranged on both sides of the linear cooling water tank 1 and are distributed sequentially and at intervals with the multiple conductor rollers 15, so that the cooling water can cool the conductor sheath from both sides. The protruding lugs 6 on both sides of the output end of the spray column pipe 5 fix and support the limiting frame 7. The spiral vortex shaft 14 at the outer end of the supporting limiting frame 7 is located directly below the liquid outlet end of the spray column pipe 5, which can form a vortex on the sprayed cooling water to enhance cooling. Uniformity is ensured, and the spiral vortex shaft 14 is also positioned directly above the cooling water tank 1, further enhancing the cooling effect. The cooling water filling the linear cooling water tank 1 flows under gravity to the flat bottom plate 9 fixed in the middle of its lower inner wall. The side guide inclined plates 8, which are symmetrically fixed at both ends of the flat bottom plate 9, guide the water flow, allowing it to be filtered through several filter screen holes 10 on the surface of the flat bottom plate 9 before flowing back to the bottom circulation water tank 3. The flat bottom plate 9 is located at the connection between the cooling water tank 1 and the bottom circulation water tank 3, serving as a transition and support. The filter screen holes 10 can remove impurities in the water, ensuring the cleanliness of the cooling water. The load-bearing bottom plate 12 connected to the lower end of the bottom circulation water tank 3 provides load-bearing and stable support for the entire device. Through the synergistic action of the above components, the cooling water continuously circulates under the drive of the circulating pump 4. With the cooperation of the spray column pipe 5 and the spiral vortex shaft 14, efficient cooling of the wire sheath is achieved, while water resource utilization is improved through recycling.
