Abstract

This invention relates to the field of cable cleaning, specifically to a surface cleaning device for power cable production, comprising a cleaning fluid tank internally divided into two independent sealed spaces, and a support platform mounted above the cleaning fluid tank. This invention achieves automatic matching of the cleaning fluid supply volume with the copper wire conveying speed through the cooperation of an internal sealing plug on the roller, a spring, and centrifugal force, avoiding excessive waste from fixed fluid supply. The cleaning fluid tank has two independent sealed spaces, allowing excess cleaning fluid from the coating section to be recycled. Furthermore, the deoxidizing cleaning fluid and the polishing rinsing water are stored separately to prevent contamination, extending the service life of the cleaning fluid and reducing waste discharge.

The composite cleaning method, employing chemical dissolution followed by gentle reciprocating polishing, results in more thorough and efficient cleaning without damaging the copper wire substrate, ensuring its conductivity and mechanical properties.

Description

Technical Field

[0001] This invention relates to the field of cable cleaning, and more specifically to a surface cleaning device for power cable production. Background Technology

[0002] The core conductive medium of wires and cables is copper conductor, and its surface cleanliness directly determines the cable's conductivity, insulation interface bonding strength, and long-term operational reliability. During the drawing, storage, and transportation of copper wires, drawing lubricant, dust, and metal debris can easily remain on the surface, and react with oxygen and moisture in the air to form an oxide layer.

[0003] In patent application CN118543577B, published on 2024-09-27 and entitled "A Cable Surface Cleaning Device and Cleaning Method for a Cable Production Line," this application discloses a cable surface cleaning device and cleaning method for a cable production line. The device includes a base, with a dry cleaning mechanism mounted on top of the base. The dry cleaning mechanism includes a first support, which is fixedly mounted on the top of the base. The first support is hollow, and a mounting cylinder is movably mounted on the first support via bearings. A stiff brush is fixedly mounted inside the mounting cylinder. A first sliding groove is formed on the surface of the base, and a first support is slidably mounted inside the first sliding groove. A first gear is rotatably mounted on the right side of the first support. A baffle is fixedly mounted on the surface of the mounting cylinder. This invention, through the dry cleaning mechanism, can scrape and clean stubborn stains on the cable surface. Using a scraping method can more effectively remove these difficult-to-clean substances, ensuring that the cleaning mechanism thoroughly cleans every corner of the cable surface, thus improving cleaning quality.

[0004] Among the aforementioned patents or prior art, existing copper wire cleaning methods are mainly divided into purely mechanical cleaning and chemical cleaning. Existing chemical cleaning involves spraying a cleaning machine onto the surface of the copper wire, and after a reaction, the oxide layer on the surface is peeled off. However, existing chemical cleaning requires a long time to produce a reaction after spraying, which greatly reduces the cleaning efficiency. Moreover, both spraying and immersion cleaning require a large amount of cleaning solution, thereby increasing the cleaning cost.

[0005] Therefore, it is necessary to invent a surface cleaning device for power cable production to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a surface cleaning device for power cable production. This device solves the problems of serious waste of cleaning solution, low efficiency of oxide layer removal, uneven cleaning effect and easy damage to copper wires in the prior art by adaptive centrifugal quantitative liquid coating, immediate heating after liquid coating to accelerate oxidation reaction, single motor synchronous drive reciprocating brushing, and partitioned recycling of cleaning solution.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a surface cleaning device for power cable production, comprising a cleaning liquid tank, the cleaning liquid tank being divided into two independent sealed spaces, a support platform being installed above the cleaning liquid tank, and symmetrical grid grooves being provided above the support platform, with the two sets of grid grooves located above the corresponding independent sealed spaces, an inlet pipe being symmetrically installed through one side of the cleaning liquid tank, and an outlet pipe being symmetrically installed through the other side of the cleaning liquid tank, with the two sets of inlet and outlet pipes respectively communicating with the interior of the corresponding independent spaces, and fixed seats being symmetrically installed on one side above the support platform, with rollers symmetrically rotatably connected between the two sets of fixed seats, and absorbent cotton tubes being sleeved on both sets of rollers, with both sets of rollers located above a set of grid grooves; A protective frame is installed on the other side above the bearing platform. Cleaning brushes are symmetrically arranged inside the protective frame. A heating chamber is installed between the protective frame and the fixed seat, and the heating chamber, the two sets of cleaning brushes, and the two sets of rollers are at the same horizontal position.

[0008] As a preferred embodiment of the present invention, cavities are symmetrically provided in both sets of rollers, and a pulley is sleeved on the upper roller. Annular grooves are provided on the surfaces of both sets of rollers, and the absorbent cotton tube is fitted into the annular grooves. Through holes are provided in an annular arrangement between the cavities and the inner walls of the annular grooves.

[0009] As a preferred embodiment of the present invention, limit cylinders are installed in a ring-shaped arrangement on the inner wall of the cavity, and each set of limit cylinders is slidably connected to a limit rod. A sealing plug is installed on one side of each set of limit rods, and each set of sealing plugs passes through the corresponding through hole.

[0010] As a preferred embodiment of the present invention, each group of sealing plugs has a flat surface on the side away from the limiting cylinder, and each group of limiting cylinders is fitted with a spring between itself and the corresponding limiting rod.

[0011] As a preferred embodiment of the present invention, two sets of sealing cylinders are sequentially installed on the side of the two sets of fixed seats away from the roller shaft, and the sealing cylinders on the same side are connected by pipes. The sealing cylinders are also connected to the liquid supply pipe. Each set of sealing cylinders is located at both ends of the corresponding roller shaft. Each set of roller shafts is axially connected to a connecting cylinder at both ends. The surface of the connecting cylinder is symmetrically provided with openings, and the connecting cylinder is rotatably connected to the inner wall of the corresponding sealing cylinder.

[0012] As a preferred embodiment of the present invention, a drive motor is installed on one side of one set of the sealing cylinders, and the output end of the drive motor is connected to the corresponding connecting cylinder shaft. Drive gears are fixedly sleeved on both sets of roller shafts, and the two sets of drive gears mesh with each other.

[0013] As a preferred embodiment of the present invention, guide shafts are symmetrically installed on one side of both sets of cleaning brushes, and each set of guide shafts is connected through the inner wall of the protective frame. A second spring is sleeved on each set of guide shafts, and the two ends of the second spring are respectively attached to the inner wall of the protective frame and the cleaning brush.

[0014] As a preferred embodiment of the present invention, push rods are installed on the other side of both sets of cleaning brushes, and the push rods are connected through the inner wall of the protective frame. A rotating disk is rotatably connected to the side of the protective frame near the push rod. Multiple sets of trapezoidal grooves are arranged in a ring on the side of the rotating disk near the protective frame, and the inner wall of the trapezoidal grooves fits against the corresponding push rods.

[0015] As a preferred embodiment of the present invention, a pulley is installed on the side of the rotating disk away from the protective frame, and a connecting belt is attached between the pulley and the second pulley.

[0016] As a preferred embodiment of the present invention, a high-pressure water pump is installed above the protective frame, and a nozzle is installed above the inner wall of the protective frame. The nozzle is connected to the high-pressure water pump pipeline and is oriented between the two sets of cleaning brushes.

[0017] Compared with the prior art, the technical effects and advantages provided by the present invention in the above technical solution are as follows: 1. By coordinating the sealing plug, spring, and centrifugal force inside the roller, the flow rate of the cleaning fluid is automatically matched with the speed of the copper wire conveying. The faster the copper wire moves, the higher the roller speed, the wider the sealing plug opens, and the more fluid is supplied; conversely, the fluid supply decreases, avoiding excessive waste at low speeds in a fixed fluid supply system. Furthermore, the cleaning fluid tank is divided into two independent sealed spaces. Excess cleaning fluid dripping from the coating section flows directly back to the corresponding cleaning fluid storage chamber through a grid channel, achieving recycling. Separate storage of the oxidation cleaning fluid and the polishing rinse water prevents contamination, extending the service life of the cleaning fluid and reducing wastewater discharge and treatment costs.

[0018] 2. By arranging the heating chamber adjacent to the coating section, the copper wire immediately enters a heated environment at a set temperature after coating. This accelerates the chemical reaction between the cleaning solution and the oxide layer, allowing most of the oxide layer to be completely dissolved within the heating chamber, significantly reducing the subsequent polishing load. Furthermore, by accelerating the chemical reaction through heating to dissolve most of the oxide layer, and then using gentle, reciprocating polishing to remove any remaining stubborn residue, this method is more thorough than pure chemical cleaning and more efficient than pure physical polishing, without damaging the copper wire substrate, thus ensuring the conductivity and mechanical properties of the copper wire.

[0022] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] This invention provides, for example Figure 1-9The surface cleaning device for power cable production shown includes a cleaning liquid tank 101, which is divided into two independent sealed spaces. A support platform 102 is installed above the cleaning liquid tank 101. A grid groove 103 is symmetrically opened above the support platform 102, and the two sets of grid grooves 103 are respectively located above the corresponding independent sealed spaces. A water inlet pipe 104 is symmetrically installed through one side of the cleaning liquid tank 101, and a water outlet pipe 105 is symmetrically installed through the other side of the cleaning liquid tank 101. The two sets of water inlet pipes 104 and water outlet pipes 105 are respectively connected to the interior of the corresponding independent spaces. A fixed seat 201 is symmetrically installed on one side of the support platform 102. A roller 202 is symmetrically rotatably connected between the two sets of fixed seats 201. A water-absorbing cotton tube 204 is sleeved on each set of rollers 202, and the two sets of rollers 202 are both located above a set of grid grooves 103. A protective frame 301 is installed on the other side above the carrying platform 102. Cleaning brushes 302 are symmetrically arranged inside the protective frame 301. A heating chamber 313 is installed between the protective frame 301 and the fixed seat 201. The heating chamber 313, the two sets of cleaning brushes 302, and the two sets of rollers 202 are at the same horizontal position.

[0024] The two independent sealed spaces inside the cleaning fluid tank 101 allow for separate storage of the deoxidizing cleaning fluid and the polishing rinsing water, preventing cross-contamination. Two sets of grid channels 103 collect liquids dripping from the coating and cleaning sections, allowing them to flow back to their respective independent sealed spaces for liquid recycling. The inlet pipe 104 and outlet pipe 105 facilitate quick replacement of the liquids in their respective spaces. Symmetrically arranged rollers 202 drive the absorbent cotton cylinders 204 to rotate synchronously, ensuring uniform coating of the copper wire's upper and lower surfaces. The absorbent cotton cylinders 204 are located within the grid channels 101. Above section 3, excess cleaning fluid can be directly returned to the cleaning fluid tank 101 through the grid groove 103, avoiding liquid accumulation and waste; the cleaning brushes 302 arranged symmetrically above and below can scrub the oxide pool on the surface of the copper wire, removing the stubborn oxide layer remaining after the heating reaction; the protective frame 301 can prevent oxide particles and copper chips generated during the polishing process from splashing; the heating chamber 313 is installed between the coating section and the polishing section, so that the copper wire after coating immediately enters the heating environment, accelerating the chemical reaction between the cleaning fluid and the oxide layer, dissolving most of the oxide layer, and significantly reducing the subsequent polishing load.

[0025] Furthermore, in the above structure, cavities 215 are symmetrically opened in both sets of rollers 202, and a pulley 309 is sleeved on the upper roller 202. Annular grooves 203 are opened on the surfaces of both sets of rollers 202, and the absorbent cotton tube 204 is fitted into the annular groove 203. Through holes 205 are opened in an annular distribution between the cavity 215 and the inner wall of the annular groove 203.

[0026] The cavity 215 inside the roller 202 serves as a temporary storage chamber for the cleaning fluid, providing a continuous and stable supply of fluid to the absorbent cotton cylinder 204. The annularly distributed through holes 205 allow the cleaning fluid in the cavity 215 to penetrate evenly into the absorbent cotton cylinder 204, ensuring that the absorbent cotton cylinder 204 remains moist and preventing dry rubbing.

[0027] Furthermore, in the above structure, limit cylinders 209 are installed in a ring on the inner wall of cavity 215. Each set of limit cylinders 209 is slidably connected to a limit rod 208. Each set of limit rods 208 has a sealing plug 206 installed on one side, and each set of sealing plugs 206 passes through the corresponding through hole 205.

[0028] By cooperating with the limiting cylinder 209 and the limiting rod 208, the movement direction of the sealing plug 206 is precisely limited, ensuring that it can only move axially along the through hole 205; the sealing plug 206 can automatically open according to the centrifugal force of the rotating roller 202, thereby controlling the flow rate of the cleaning fluid, and the rotation speed of the roller 202 can be adjusted according to the flow rate of the copper wire, and the flow rate of the cleaning fluid can also be adjusted accordingly.

[0029] Furthermore, in the above structure, each set of sealing plugs 206 has a flat surface 207 on the side away from the limiting cylinder 209, and each set of limiting cylinders 209 is connected to the corresponding limiting rod 208 with a spring 210.

[0030] Spring 210 provides a reset force to the sealing plug 206, ensuring that the sealing plug 206 is in its initial position when no external force is applied. The design of the plane 207 of the sealing plug 206 allows the sealing plug 206 to maintain its initial position inside the through hole 205. At this time, there is still a gap between the plane 207 and the inner wall of the through hole 205, so that the cleaning fluid can pass through even if the rotation speed of the roller 202 is low.

[0031] Furthermore, in the above structure, two sets of sealing cylinders 211 are sequentially installed on the side of each of the two sets of fixed seats 201 away from the roller shaft 202, and the sealing cylinders 211 on the same side are connected by pipes. The sealing cylinders 211 are also connected to the liquid supply pipe. Each set of sealing cylinders 211 is located at both ends of the corresponding roller shaft 202. Each set of roller shafts 202 has a connecting cylinder 212 axially connected to both ends. The surface of the connecting cylinder 212 is symmetrically provided with openings, and the connecting cylinder 212 is rotatably connected to the inner wall of the corresponding sealing cylinder 211.

[0032] The sealing cylinder 211 and the connecting cylinder 212 cooperate to form a rotary sealing structure, which prevents the cleaning fluid from leaking from both ends of the roller shaft 202 and provides rotational support for the roller shaft 202. Furthermore, by continuously replenishing the cleaning fluid into the sealing cylinder 211 and allowing external cleaning fluid to enter the cavity 215 inside the roller shaft 202 through the opening on the surface of the connecting cylinder 212, the cleaning fluid can be continuously replenished.

[0033] Furthermore, in the above structure, a drive motor 213 is installed on one side of a set of sealing cylinders 211, and the output end of the drive motor 213 is axially connected to the corresponding connecting cylinder 212. Drive gears 214 are sleeved and fixed on both sets of rollers 202, and the two sets of drive gears 214 mesh with each other.

[0034] The drive motor 213 provides power to the entire device, and drives the lower roller 202 to rotate through the connecting cylinder 212; the two sets of meshing drive gears 214 can make the upper and lower rollers 202 rotate synchronously, ensuring that the linear speed of the upper and lower absorbent cotton cylinders 204 is completely consistent with the copper wire conveying speed, and also ensuring that no pulling force is generated on the copper wire. Furthermore, in the above structure, guide shafts 303 are symmetrically installed on one side of each of the two sets of cleaning brushes 302, and each set of guide shafts 303 is connected through to the inner wall of the protective frame 301. A second spring 304 is sleeved on each set of guide shafts 303, and the two ends of the second spring 304 are respectively attached to the inner wall of the protective frame 301 and the cleaning brush 302.

[0035] The guide shaft 303 precisely guides the movement direction of the cleaning brush 302, ensuring that it can only move radially along the copper wire and will not deviate; the spring 304 provides a constant preload pressure for the cleaning brush 302, while ensuring uniform brushing pressure.

[0036] Furthermore, in the above structure, push rods 305 are installed on the other side of both sets of cleaning brushes 302, and the push rods 305 are connected through the inner wall of the protective frame 301. A rotating disk 306 is rotatably connected to the side of the protective frame 301 near the push rods 305. Multiple sets of trapezoidal grooves 307 are arranged in a ring on the side of the rotating disk 306 near the protective frame 301, and the inner wall of the trapezoidal grooves 307 fits against the corresponding push rods 305.

[0037] When the rotating disk 306 rotates, the trapezoidal groove 307 on its surface pushes the push rod 305 to reciprocate linearly through the inclined plane, and under the reset action of the spring 304, it drives the cleaning brush 302 to reciprocate along the copper wire axis; this reciprocating brushing method can effectively remove stubborn oxide spots remaining after the heating reaction.

[0038] Furthermore, in the above structure, a pulley 308 is installed on the side of the rotating disk 306 away from the protective frame 301, and a connecting belt 310 is attached between the pulley 308 and the pulley 309.

[0039] The power of pulley 309 is transmitted to pulley 308 via belt 310, thereby driving the rotating disk 306 to rotate, achieving synchronous drive of the coating mechanism and the washing mechanism; at the same time, it ensures the precise synchronization of the copper wire conveying speed, coating speed and polishing speed, ensuring consistent cleaning effect.

[0040] Furthermore, in the above structure, a high-pressure water pump 311 is installed above the protective frame 301, and a nozzle 312 is installed above the inner wall of the protective frame 301. The nozzle 312 is connected to the high-pressure water pump 311 through a pipe, and the nozzle 312 is oriented between the two sets of cleaning brushes 302.

[0041] High-pressure air is generated by the high-pressure water pump 311 and sprayed through the nozzle 312 onto the contact area between the copper wire and the cleaning brush 302. This can promptly blow away the oxide particles and copper shavings that have been polished off, preventing particles from embedding into the cleaning brush 302 and causing secondary scratches on the copper wire. At the same time, it can keep the surface of the cleaning brush 302 clean, prevent the accumulation of debris from affecting the polishing effect, and effectively extend the service life of the cleaning brush 302.

[0042] like Figure 1-9 As shown, the drive motor 213 is started, causing its output end to drive the connecting cylinder 212 connected to its shaft to rotate; the connecting cylinder 212 drives the lower roller shaft 202 to rotate synchronously, and through two sets of meshing drive gears 214, the upper and lower roller shafts 202 achieve synchronous reverse rotation; at the same time, the second pulley 309 on the upper roller shaft 202 drives the first pulley 308 to rotate through the connecting belt 310, thereby driving the rotating disk 306 to rotate synchronously.

[0043] At this time, the external liquid supply end continuously supplies deoxidizing cleaning fluid into the sealing cylinder 211. The cleaning fluid enters the cavity 215 inside the roller 202 through the opening on the surface of the connecting cylinder 212. When the roller 202 rotates, the sealing plug 206 in the cavity 215 is subjected to centrifugal force, overcoming the reset force of the spring 210 and moving outward along the limiting cylinder 209, thus opening the through hole 205. The faster the roller 202 rotates, the greater the centrifugal force, the greater the opening amplitude of the sealing plug 206, and the more cleaning fluid passes through, thus achieving the desired liquid supply and flow rate. Automatic matching of copper wire conveying speed; even if the roller 202 rotates at a low speed, the gap between the sealing plug 206 plane 207 and the inner wall of the through hole 205 can ensure the basic liquid supply; the cleaning liquid permeates evenly through the through hole 205 into the absorbent cotton cylinder 204 in the annular through groove 203, and when the copper wire passes between the upper and lower absorbent cotton cylinders 204, the cleaning liquid is evenly applied in all directions; excess cleaning liquid flows back to the corresponding independent sealed space of the cleaning liquid tank 101 through the lower grid groove 103 to achieve recycling.

[0044] At this point, the copper wire, after the coating is completed, enters the heating chamber 313 in a horizontal straight line. It remains in the set temperature environment for a predetermined time. The cleaning solution reacts rapidly with the copper oxide and cuprous oxide layers on the surface of the copper wire, dissolving most of the oxide layer. The heated copper wire then enters the protective frame 301 and passes between the upper and lower cleaning brushes 302. As the rotating disk 306 continues to rotate, the trapezoidal grooves 307 on its surface periodically push the push rod 305 towards the copper wire through the inclined plane. Combined with the restoring force of the second spring 304, this drives the cleaning brush 302 to perform a high-speed reciprocating linear motion along the copper wire axis. The second spring 304 simultaneously provides a constant pre-tightening pressure to the cleaning brush 302, ensuring it remains tightly fitted to the copper wire surface and thoroughly removing any remaining stubborn oxide spots. The guide shaft 303 ensures that the cleaning brush 302 moves only radially along the copper wire and does not deviate.

[0045] Finally, the high-pressure water pump 311 generates a high-pressure airflow, which is continuously sprayed through the nozzle 312 onto the contact area between the copper wire and the cleaning brush 302. This promptly blows away the oxide particles and copper shavings washed off the surface of the copper wire, preventing particles from embedding into the cleaning brush 302 and causing secondary scratches on the copper wire. At the same time, it keeps the surface of the cleaning brush 302 clean, preventing debris accumulation from affecting the cleaning effect. The protective frame 301 blocks the splashing of oxide particles and copper shavings, protecting the operators and the workshop environment. The wastewater containing oxide particles generated during the brushing process flows back to another independent sealed space of the cleaning liquid tank 101 through the corresponding grid groove 103 below the protective frame 301, completely isolating it from the deoxidation cleaning liquid and avoiding cross-contamination. The liquids in the two independent spaces can be replaced and replenished respectively through the corresponding inlet pipe 104 and outlet pipe 105.

[0046] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
