Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of copper wire processing equipment, specifically to a dewatering device for a metal wire drawing machine. Background Technology
[0002] Electricity is transmitted through cables, and the key component of a cable is the conductor. The most important parameter of a conductor is its electrical conductivity. In actual production, moisture may adhere to the surface of the conductor after certain processing steps. In subsequent processes, due to the combined effects of various environmental conditions and the conductor's own physicochemical factors, oxidation can occur on the conductor surface.
[0003] During the copper monofilament drawing process, the temperature of the copper monofilament is extremely high. Therefore, the drawn monofilament is cooled at the end of the drawing process. This cooling step causes the monofilament to come into contact with the coolant. Due to the very high conductor speed, the coolant adhering to the conductor surface contains moisture. After winding, this moisture easily oxidizes inside the high-temperature, sealed coil, forming copper rust. Monofilaments with copper rust cannot be used and must be scrapped, increasing the company's operating costs.
[0004] In the wire drawing process, to prevent oxidation caused by coolant adhesion, the cable industry typically adds a drying process, using high-pressure gas to blow away the coolant adhering to the conductor surface. Other existing drying methods also add a drying step to remove moisture or wipe away water. However, existing air-blowing drying methods cannot effectively blow air from all directions, creating blind spots. Furthermore, the single drying method results in insufficient drying. Moreover, most existing drying equipment has a monolithic structure, making operation inconvenient during wire drawing assembly and installation, and the inconvenient disassembly design makes maintenance difficult. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a dehydration device for metal wire drawing machines, which solves the problem of insufficient drying caused by the current method of drying coolant adhering to the conductor surface through a blowing process in the wire drawing process.
[0006] This utility model provides a dewatering device for a metal wire drawing machine, comprising:
[0007] The enclosure has an inlet and an outlet through-hole on its outer wall, and contains an aqueous solution.
[0008] A partition is disposed inside the box, and there is a gap between the bottom of the partition and the box, so that the two sides of the partition are connected to each other. The inlet hole and the outlet hole are respectively located on the two sides of the partition.
[0009] A guide wheel is disposed on the partition plate; the liquid level of the deionized water solution is higher than the bottom height of the guide wheel.
[0010] As can be seen from the above technical solution, the metal wire drawing machine dewatering device provided by this utility model solves the problem that in the production of cable wire drawing, the copper wire often turns black due to oxidation after a certain period of time because the water stains and other chemical residues attached to its surface are not dried, which leads to an increase in its resistivity and even scrapping of the batch of copper wire.
[0011] Optionally, the line connecting the inlet and outlet through-holes is located in the same vertical plane as the axial center point of the guide wheel. The inlet through-hole passes through the outlet through-hole of the guide wheel to prevent the wire from detaching from the guide wheel and to ensure the reliability of the device.
[0012] Optionally, the outer wall of the guide wheel is concave arc-shaped. This is used to prevent the metal wire from detaching from the guide wheel and to ensure the reliability of the device.
[0013] Optionally, the bottom of the partition plate has a groove, and a bearing is provided between the two sides of the groove. The guide wheel is mounted on the partition plate via the bearing. Positioning the guide wheel within the groove at the bottom of the partition plate facilitates installation compared to positioning it in the middle of the partition plate.
[0014] Optionally, the aqueous solution is industrial ethanol, 1,2-propanediol, or glycerol.
[0015] By adopting the above technical solution, this application has the following technical effects:
[0016] The dewatering device for metal wire drawing machines provided by this utility model changes the previous dewatering methods such as blowing and heating drying. It adopts an aqueous solution. Based on the principle that organic solvents and water are miscible, after the monofilament enters the dewatering solution, the water on the surface of the monofilament can be miscible with the dewatering solution. The water attached to the monofilament is dissolved in the dewatering solution, so that the water is removed from the surface of the monofilament.
[0017] In addition to aqueous solutions, organic solvents are chosen so that they do not react with the metal wire, can remove heat from the surface of the metal wire, and lower the temperature of the single wire. Attached Figure Description

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0025] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.
[0026] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0027] In one embodiment, such as Figure 1-3 As shown, a dewatering device for a metal wire drawing machine is provided, including a housing 1, a partition 2, and a guide wheel 3. The outer wall of the housing 1 is provided with an inlet hole 11 and an outlet hole 12. A dewatering solution is provided inside the housing 1. The partition 2 is disposed inside the housing 1, and there is a gap between the bottom of the partition 2 and the housing 1, so that the two sides of the partition 2 are connected to each other. The inlet hole 11 and the outlet hole are located on the two sides of the partition 2, respectively. The guide wheel 3 is disposed on the partition 2, and the liquid level of the dewatering solution is higher than the bottom height of the guide wheel 3.
[0028] The dewatering device for the metal wire drawing machine provided in this embodiment solves the problem that during cable wire drawing production, the copper wire surface often oxidizes and turns black after a certain period of time due to the failure to dry the water and chemical residues on the surface, leading to an increase in resistivity and even the scrapping of the entire batch of copper wire. The dewatering solution adhering to the surface of the monofilament in the through-hole 12 does not react with the metal wire, but can remove heat from the surface of the monofilament and reduce its temperature.
[0029] By immersing the metal wire in the dehydration solution, the moisture remaining on the surface of the metal wire can be completely removed, ensuring the dehydration effect and guaranteeing product quality.
[0030] like Figure 3 As shown, the line connecting the inlet through-hole 11 and the outlet through-hole 12 is located in the same vertical plane as the axial center point of the guide wheel 3. This prevents the metal wire from detaching from both sides of the guide wheel 3, ensuring the reliability of the device. Simultaneously, the fact that the inlet through-hole 11, the outlet through-hole 12, and the axial center point of the guide wheel 3 are in the same vertical plane minimizes the distance the metal wire travels, improving the water removal efficiency.
[0031] like Figure 2 As shown, the outer wall of the guide wheel 3 is concave arc-shaped. The concave arc shape is also used to prevent the metal wire from detaching from the guide wheel 3, ensuring the reliability of the device.
[0032] like Figure 2 As shown, a groove 21 is provided at the bottom of the partition 2, and a bearing 22 is provided between the two sides of the groove 21. The guide wheel 3 is mounted on the partition 2 through the bearing 22.
[0033] See Figure 1 The outer edge of the guide wheel 3 can be elliptical, which can prevent the wire from detaching from the guide wheel during the production of monofilaments, thus avoiding scratches on the conductor surface.
[0034] Optionally, the aqueous solution can be industrial ethanol, 1,2-propanediol, or glycerol. Utilizing the principle that organic solvents are miscible with water, after the monofilament enters the organic solvent, the water on the surface of the monofilament is miscible with the organic solvent, and the water attached to the monofilament dissolves into the organic solvent, thus removing the water from the monofilament surface. The organic solvent adhering to the surface of the monofilament at the through-hole 12 does not react with the metal wire and can carry away heat from the surface of the metal wire, lowering the temperature of the monofilament.
[0035] The working principle of the dewatering device for a metal wire drawing machine provided in this embodiment is as follows:
[0036] During operation, the water-cooled copper wire is fed into the dehydration device housing 1 through the inlet hole 11, completely immersing the copper wire in the dehydration solution. The solution absorbs the moisture remaining on the surface of the copper wire. The wire then passes through the guide wheel 3 on the partition 2 and exits through the outlet hole 12. Finally, it enters the take-up reel, thus ensuring the dryness of the metal wire, extending its storage time, and guaranteeing product quality.
[0037] The metal wire drawing machine dewatering device provided in this embodiment solves the problem that during cable wire drawing production, the copper wire often oxidizes and turns black after a certain period of time due to the failure to dry the water stains and other chemical residues on its surface, resulting in an increase in its resistivity and even scrapping the batch of copper wire.
[0038] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
