Description

Technical Field

[0001] The invention relates to the technical field of cable manufacturing, in particular to a cable conductor surface pretreatment device used in cable manufacturing. Background Art

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which can be defined as one or more insulated cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors.

[0003] When the cable is produced, there will be a lot of oily substances on the surface. If this thin oily layer remains on the conductor during cable production, the substance will expand rapidly when the conductor passes through the high-temperature mold and cause bubbles to appear on the surface of the cable insulation. In some cases, the bubbles will burst directly, causing defects in the cable and breakdown. Therefore, the oily substance needs to be cleaned. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a cable conductor surface pretreatment device for cable manufacturing in view of the deficiencies in the above-mentioned prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a cable conductor surface pretreatment device for cable manufacturing, comprising a bottom plate, two guide wheels are arranged on the top of the bottom plate, the top of the bottom plate is fixedly connected to a box body, the left and right sides of the box body are respectively provided with sealing ports, an oil cleaning mechanism is arranged inside the box body, a water-based degreasing agent is arranged inside the box body, and the water-based degreasing agent can remove the oil on the cable, the oil cleaning mechanism comprises an electric push rod, the electric push rod is fixedly connected to the inner wall of the box body, the back of the electric push rod is fixedly connected to a fixing plate, the bottom of the fixing plate is fixedly connected to a first connecting plate, the bottom of the first connecting plate is fixedly connected to a first cleaning brush, the inner wall of the box body is fixedly connected to a fixing sleeve, and the The fixing sleeve is internally slidably connected with a second connecting plate, a limiting spring is arranged between the back of the second connecting plate and the fixing sleeve, the top of the second connecting plate is fixedly connected with a second cleaning brush and a vertical plate, the back of the fixing plate is fixedly connected with a resistance rod, the first cleaning brush and the second cleaning brush are staggered, the electric push rod is started, the electric push rod drives the fixing plate to move backward, the fixing plate drives the first connecting plate at its bottom to move backward, thereby driving the first cleaning brush to move, when the fixing plate moves backward, it drives the resistance rod to move backward, thereby driving the second connecting plate at the bottom of the vertical plate to move backward through the resistance rod to resist the vertical plate, thereby driving the second cleaning brush to move backward, since the first cleaning brush and the second cleaning brush are staggered, the cable can be fully cleaned and the oil stain can be removed.

[0006] Preferably, two vertical grooves are formed inside the box body. First sliders are respectively slidably connected inside the two vertical grooves. A first spring is fixedly connected between the bottoms of the two first sliders and the vertical grooves. A moving plate is fixedly connected between the two first sliders.

[0007] Preferably, an inclined hole is formed inside the moving plate. A cross bar is fixedly connected to the right side of the first connecting plate. The cross bar movably penetrates through the inclined hole and extends outward. A sleeve plate is fixedly connected to the bottom of the moving plate. The sleeve plate sleeves the outer wall of the cable. When the first connecting plate moves backward, it will drive the cross bar to move backward. When the cross bar moves backward, it will drive the moving plate to lift under the action of the inclined hole, thereby driving the sleeve plate to lift. By reciprocating in this way, the up-and-down movement of the sleeve plate can be realized, so that the cable can be driven to shake up and down. The up-and-down shaking of the cable can effectively break the adhesion between the oil stain and the cable surface.

[0008] Preferably, a stirring mechanism is arranged inside the box body. The stirring mechanism includes a first connecting rod. The first connecting rod is fixedly connected to the left side of the first connecting plate. A first rack is fixedly connected to the bottom of the first connecting rod. A first rotating rod is rotatably connected to the bottom side inside the box body. A first gear is fixedly connected to the top of the first rotating rod. The first gear meshes with the first rack. A stirring blade is fixedly connected to the outer wall of the first rotating rod. When the first connecting plate moves back and forth, it will drive the first connecting rod to move back and forth. When the first connecting rod moves back and forth, it will drive the first rack to move, so as to drive the first rotating rod at the bottom of the first gear to rotate. When the first rotating rod rotates, it will drive the stirring blade to rotate. By the positive and negative rotation of the stirring blade, eddy currents are generated. The centrifugal force and tangential force of the eddy currents can effectively peel off the oil stain on the cable surface.

[0009] Preferably, a second rack is fixedly connected to the top of the moving plate. Two second rotating rods are rotatably connected inside the box body. A second gear is fixedly connected to the outer wall of the second rotating rod. The second gear meshes with the second rack. A flow guiding plate is fixedly connected to the outer wall of the second rotating rod. When the moving plate descends, it will drive the second rack to descend. By the descent of the second rack, the second gear will be driven to rotate, thereby driving the second rotating rod inside it to rotate. When the second rotating rod rotates, it will drive the flow guiding plate to rotate. By the rotation of the flow guiding plate, the flow path and velocity distribution of the fluid can be changed. The flow guiding plate ensures that the water-based degreasing agent evenly covers the cable surface and reduces the cleaning blind area.

[0010] Preferably, an oil stain removing mechanism is arranged inside the box body. The oil stain removing mechanism includes a first sliding groove. The first sliding groove is formed on the left and right inner walls of the box body. A second slider is slidably connected inside the first sliding groove.

[0011] Preferably, a cross plate is fixedly connected to the right side of the second slider. A second sliding groove is formed in the right side of the cross plate. A first oil-loving activated carbon plate and a second oil-loving activated carbon plate are slidably connected inside the second sliding groove. The first oil-loving activated carbon plate and the second oil-loving activated carbon plate are fixedly connected. The first oil-loving activated carbon plate and the second oil-loving activated carbon plate can adsorb the oil stains floating on the surface of the solvent, and at the same time will not adsorb the solvent. The first oil-loving activated carbon plate and the second oil-loving activated carbon plate float on the surface of the water-based degreasing agent and change with the height of the water-based degreasing agent.

[0012] Preferably, contact plates are fixedly connected to the front and rear sides of the fixing plate respectively. The contact plates are in contact with the first oil-loving activated carbon plate. A second spring is fixedly connected between the second oil-loving activated carbon plate and the inner wall of the second sliding groove. When the fixing plate moves backward, it will contact the first oil-loving activated carbon plate, causing the first oil-loving activated carbon plate and the second oil-loving activated carbon plate to move back and forth. By dynamically adjusting the adsorption position, the adsorption area is significantly enlarged. When the fixing plate is separated from the first oil-loving activated carbon plate, it will automatically reset under the action of the second spring.

[0013] The present invention adopts the above technical solutions and can bring the following beneficial effects: 1. For the cable conductor surface pretreatment device for cable manufacturing, by setting the water-based degreasing agent, the oil stains on the cable surface can be effectively removed. The combined use of the first cleaning brush and the second cleaning brush can clean the cable surface in all directions to ensure that the oil stains are completely removed, thereby improving the surface quality of the cable conductor. Moreover, the up-and-down shaking of the cable can effectively break the adhesion between the oil stains and the cable surface, making the oil stains easier to detach from the cable surface. This design significantly improves the removal efficiency of oil stains, especially when dealing with stubborn oil stains, and the shaking mechanism can accelerate the separation of oil stains.

[0014] 2. For the cable conductor surface pretreatment device for cable manufacturing, by the forward and reverse rotation of the stirring blades to generate eddy currents, the centrifugal force and tangential force of the eddy currents can effectively peel off the oil stains on the cable surface. The eddy current effect not only enhances the impact force of the water-based degreasing agent on the oil stains but also forms a peeling force on the cable surface to completely remove the stubborn oil stains. And by the rotation of the guide plate, the flow path and velocity distribution of the fluid can be changed. The guide plate ensures that the water-based degreasing agent evenly covers the cable surface and reduces the cleaning blind area.

[0015] 3. The surface pretreatment device for cable conductors in cable manufacturing can adsorb the oil stains floating on the surface of the solvent through the setting of lipophilic activated carbon plates, while avoiding adsorbing the solvent itself. This design not only improves the removal effect of oil stains, but also reduces the waste of degreasing agents, lowers the production cost, and the lipophilic activated carbon plates can automatically adjust their height according to the amount of the solvent and always float on the surface of the solvent. This design ensures that the activated carbon plates can maximize contact with the oil stains on the surface of the solvent, thereby achieving precise adsorption and improving the oil stain removal efficiency.

[0016] 4. The surface pretreatment device for cable conductors in cable manufacturing allows the lipophilic activated carbon plates to move back and forth. By dynamically adjusting the adsorption position, the adsorption area is significantly expanded. This design not only improves the adsorption efficiency, but also avoids the problem of local adsorption saturation, ensuring the uniformity and continuity of the adsorption process.

Sealing openings 4 are respectively arranged on the left and right sides of the box body 3. An oil stain cleaning mechanism 5 is arranged inside the box body 3. A water-based degreasing agent is arranged inside the box body 3. The water-based degreasing agent can remove the oil stains on the cable. The oil stain cleaning mechanism 5 includes an electric push rod 511. The electric push rod 511 is fixedly connected to the inner wall of the box body 3. A fixing plate 512 is fixedly connected to the back of the electric push rod 511. A first connecting plate 513 is fixedly connected to the bottom of the fixing plate 512.

A second connecting plate 516 is slidably connected inside the fixing sleeve 515. A limiting spring is arranged between the back of the second connecting plate 516 and the fixing sleeve 515. A second cleaning brush 517 and a vertical plate 518 are fixedly connected to the top of the second connecting plate 516. A resisting rod 519 is fixedly connected to the back of the fixing plate 512. The first cleaning brush 514 and the second cleaning brush 517 are arranged in an interleaved manner. When the electric push rod 511 is started, the electric push rod 511 drives the fixing plate 512 to move backward. The fixing plate 512 drives the first connecting plate 513 at its bottom to move backward, thereby driving the first cleaning brush 514 to move. When the fixing plate 512 moves backward, it will drive the resisting rod 519 to move backward, so as to drive the vertical plate 518 through the resisting rod 519, and drive the second connecting plate 516 at the bottom of the vertical plate 518 to move backward, thereby driving the second cleaning brush 517 to move backward. Since the first cleaning brush 514 and the second cleaning brush 517 are arranged in an interleaved manner, the comprehensive cleaning of the cable can be realized, and the oil stain can be separated. Two vertical grooves 520 are opened inside the box body 3. First sliders 521 are respectively slidably connected inside the two vertical grooves 520.

The sleeve plate 526 is sleeved on the outer wall of the cable. When the first connecting plate 513 moves backward, it will drive the cross bar 525 to move backward. When the cross bar 525 moves backward, it will drive the moving plate 523 to lift under the action of the inclined hole 524, thereby driving the sleeve plate 526 to lift. By reciprocating in this way, the up and down movement of the sleeve plate 526 can be realized, so as to drive the cable to shake up and down.

Start the electric push rod 511, and the electric push rod 511 drives the fixed plate 512 to move backward. The fixed plate 512 drives the first connecting plate 513 at its bottom to move backward, thereby driving the first cleaning brush 514 to move. When the fixed plate 512 moves backward, it will drive the contact rod 519 to move backward, so as to drive the vertical plate 518 through the contact rod 519, and drive the second connecting plate 516 at the bottom of the vertical plate 518 to move backward, thereby driving the second cleaning brush 517 to move backward. Since the first cleaning brush 514 and the second cleaning brush 517 are arranged in an interleaved manner, the cable can be comprehensively cleaned to achieve oil stain detachment. When the contact rod 519 is separated from the vertical plate 518, it will automatically reset. When the first connecting plate 513 moves backward, it will drive the cross bar 525 to move backward. When the cross bar 525 moves backward, it will drive the moving plate 523 to lift under the action of the inclined hole 524, thereby driving the sleeve plate 526 to lift. By reciprocating in this way, the up and down movement of the sleeve plate 526 can be realized, thereby driving the cable to vibrate up and down. The up and down vibration of the cable can effectively break the adhesion between the oil stain and the cable surface.
