Description

Technical Field

[0001] This invention relates to the field of cable core coating technology, specifically to a cable core coating forming device for cable processing. Background Technology

[0002] Cable core coating molding equipment is a core piece of equipment in cable production. It is mainly used to uniformly coat the cable core with insulation, sheath, or shielding layers to meet the electrical insulation, mechanical protection, and special functional requirements of the cable. The most commonly used type is the extrusion coating molding device. The coating material is added to the hopper and enters the barrel. The screw rotates and pushes the material forward. At the same time, the heating system outside the barrel and the shearing action of the screw generate heat, causing the material to gradually melt into a uniform viscous flow. The molten material forms a continuous and uniform flow in the screw groove and enters the die head. The cable core passes through the center of the die core. The molten material is pushed into the die head by the screw and extruded through the annular gap between the die core and the die sleeve to form a continuous tubular coating layer. Under pressure, the molten material is tightly adhered to the surface of the preheated cable core to form a dense insulation or sheath layer. The coated cable enters a cooling water tank and is rapidly cooled and solidified by cold water. The solidified coating layer maintains a stable shape and possesses the required physical and electrical properties.

[0003] However, existing extrusion-type cable core coating molding devices use molten plastic that flows evenly from the annular gap of the mold to wrap the wire core passing through the center of the mold. While this can fill in the unevenness of the wire core surface to some extent, it cannot compensate for the bending, skewing, or vibration of the wire core. When the wire core bends and enters the mold, it cannot maintain its center and will stick to one side of the mold core. In addition, the unevenness of the surface and the fluctuating gaps in some areas result in one side of the wire core being covered very thinly and the other side being too thick. Furthermore, the mold exit is in direct contact with the air, and the temperature is lower than that inside the barrel and mold cavity. When the molten plastic reaches the mold opening, it cools down locally and its viscosity increases, making it impossible for it to be completely carried away by the wire core. It will gradually stick to the edge of the mold opening, accumulate and solidify, forming residual material. When the wire core passes through the mold opening after coating, it will catch and drag the residual material from the mold opening, tearing off the semi-solidified molten material and sticking it to its own surface, directly forming lumps, particles, and burrs, which cannot meet the smooth requirements of the cable insulation layer and sheath layer. Summary of the Invention

[0004] To address the existing technical problems of wire core bending, skewness, and vibration, which result in one side of the wire core being excessively thin and the other side being excessively thick after wire core wrapping, as well as the formation of lumps, particles, and burrs on the outer wall of the wire core after wrapping, this invention provides a cable core wrapping and forming device for cable processing.

[0007] The base has a cavity that moves in conjunction with a bevel gear, a bevel gear ring, and a movable column. The movable column is fixedly connected to the inner wall of the cavity. One end of the fixed plate is fixedly connected to the abutment plate. The protruding part of the outer wall of the fixed frame is fixedly connected to the second piston rod.

[0008] The arc adjustment assembly includes a first oil tank fixed to one side of the delivery wheel, a first piston rod slidably connected to the first oil tank, a movable seat fixed to one end of the first piston rod, a plurality of rotating plates hinged at equal angles to one end of the movable seat, a fixed block hinged to one side of the rotating plate, a push plate fixed to one side of the fixed block, and the push plate movably connected to the arc plate.

[0009] The push plate has an arc-shaped cross-section. A spring is provided between the push plate and the fixed shaft. One end of the spring is fixedly connected to the outer wall of the fixed shaft, and the other end of the spring is fixedly connected to the inner wall of the push plate.

[0010] The first oil tank and the second oil tank are connected by a hose, and the movable seat is slidably connected to the fixed shaft.

[0011] The cleaning assembly includes a turntable fixed to one side of one of the delivery wheels via a connecting shaft. A fixed rod is eccentrically fixed to one end of the turntable. A movable frame is slidably connected to the fixed rod. An elastic telescopic rod is fixed to one side of the movable frame. One side of the elastic telescopic rod is fixedly connected to a fixed frame. A connecting frame is fixed to one side of the movable frame. A movable ring is fixed to one side of the connecting frame. A rotating ring is rotatably connected inside the movable ring. One end of the rotating ring is fixedly connected to the cleaning wire.

[0012] The outer wall of the rotating ring is fixed with a protrusion, and the moving ring has a threaded groove that moves in conjunction with the protrusion.

[0013] The fixed ring is fixedly connected to the fixed seat, the rotating ring is limited to the fixed seat for rotation, and the fixed seat has a cavity that cooperates with the fixed plate and the contact plate.

[0014] A motor is fixed to one end of the delivery wheel, the outer wall of the cleaning wire is wrapped with an elastic abrasive bristle layer and is arranged at an angle toward the wire core, and the arc plate is a metal sheet with elastic deformation capability.

[0015] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following: 1. This invention achieves synchronous rotation of the lead screws on both sides through the meshing transmission of bevel gears and bevel gear rings, thereby driving the moving column, fixed frame, delivery wheel, and contact plate to move synchronously. The contact plate adopts an outwardly convex arc-shaped cross-section design, which cooperates with the staggered and symmetrically distributed delivery wheels to not only reliably straighten the cable core, but also to achieve centered clamping of the cable core, ensuring that the cable core always travels in a straight line along the center of the mold. This solves the technical defects such as eccentricity and uneven thickness of the coating layer caused by wire core bending, skewing, and shaking, significantly improves the concentricity and density of the coating layer, effectively protects the electrical insulation performance of the cable, and reduces the safety hazards caused by insulation layer defects in the cable.

[0016] 2. This invention achieves stable hydraulic oil transmission through the sliding of the piston rod within the oil tank, which in turn drives the piston rod and moving seat on the other side. This movement, via the rotating plate and push plate, drives the arc-shaped plate. Combined with a spring reset structure, the arc-shaped plate can adaptively deform elastically according to changes in the cable core diameter, further enhancing the stability of the core clamping. Simultaneously, the convex arc-shaped structure of the contact plate, the elastic deformation characteristics of the arc-shaped plate, and the elastic abrasive bristles of the cleaning wire form a triple adaptive structure, automatically adapting to cable cores of different thicknesses. This eliminates the need for manual mold replacement or clamp adjustment, significantly expanding the applicable wire diameter range of the equipment, effectively reducing line changeover and debugging time, and improving production flexibility and continuity. Furthermore, the stable, centered posture of the core greatly reduces friction between it and the inner wall of the mold, not only reducing mold wear and extending mold life but also preventing scratches on the core and ensuring its integrity.

[0017] 3. This invention uses a turntable and an eccentric fixing rod to drive the moving frame to reciprocate. The moving ring is displaced via a connecting frame. The moving ring, through a threaded groove and a protrusion on the outer wall of the rotating ring, cleverly converts linear motion into rotational motion, which in turn drives the cleaning wire to rotate synchronously. The outer wall of the cleaning wire is covered with radially arranged elastic abrasive bristles, which have good self-adaptive bending elasticity and can closely fit the surface of cable cores of different diameters. This allows for simultaneous cable core coating and surface cleaning. Through continuous scraping and polishing by the elastic abrasive bristles, surface defects such as lumps, particles, and burrs in the coating layer caused by residual material accumulation at the die opening can be effectively removed, ensuring a smooth and flat coating surface that fully meets the appearance and performance requirements of the cable insulation and sheath layers. This avoids downtime and rework due to surface defects, significantly improves production efficiency and product qualification rate, and reduces production energy consumption and costs.

[0022] The technical solutions of the present invention will now be described with reference to the accompanying drawings. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0023] like Figures 1 to 11As shown, the present invention provides a cable core coating and forming device for cable processing, including a main body 1, a mold 2 fixed at the head of the main body 1, a base 3 at the entrance of the mold 2, a fixed seat 15 at the exit of the mold 2, symmetrically arranged size adjustment components inside the mold 2, a contact plate 5 fixed at one end of the size adjustment components, and the contact plate 5 having an outwardly convex arc surface cross-section, a plurality of delivery wheels 6 symmetrically arranged in a staggered manner inside the mold 2, an arc adjustment component inside the delivery wheels 6, a fixed shaft 8 fixed between two delivery wheels 6, and an arc plate 9 fixed to the outer wall of the two delivery wheels 6, a cleaning component inside the fixed seat 15, a plurality of cleaning wires 11 fixed at equal angles on one side of the cleaning component, a fixed ring 12 fixed at one end of the cleaning wires 11, a second oil tank 14 on one side of the size adjustment component, the second oil tank 14 being fixedly connected to a protruding position on the inner wall of the mold 2, and a second piston rod 13 being slidably connected inside the second oil tank 14.

[0024] It should be noted that the cable core passes sequentially through the base 3 at the entrance of the mold 2 at the head of the main body 1, the mold 2, and the fixed seat 15 at the exit. The size adjustment component inside the mold 2 drives the contact plate 5 to move, which cooperates with the multiple delivery wheels 6 arranged symmetrically and offset inside the mold 2 to clamp the cable core. The convex arc surface of the contact plate 5 is adapted to the wire core. The arc adjustment component inside the delivery wheel 6, together with the fixed shaft 8 between the two delivery wheels 6 and the arc plate 9 on the outer wall, adjusts the arc of the wire core. The second piston rod 13 on one side of the size adjustment component slides and limits the adjustment in the second oil tank 14. The cleaning component inside the fixed seat 15 drives the multiple cleaning wires 11 fixed at equal angles to rotate, cleaning the wrapped cable core and realizing the wrapping and forming of the cable core.

[0025] The size adjustment assembly includes bevel gears 401 symmetrically arranged in the base 3. One end of one bevel gear 401 is fixed with a motor, and a bevel gear ring 402 meshes with one side of the bevel gear 401. One end of the bevel gear 401 is fixed with a lead screw 403. The lead screw 403 is threadedly connected to a moving column 404. One end of the moving column 404 is fixed with a fixing frame 405. The fixing frame 405 is rotatably connected to the delivery wheel 6, and a fixing plate 406 is fixed to one side of the fixing frame 405.

[0026] It should be noted that the motor drives one of the bevel gears 401 to rotate. This bevel gear 401 meshes with the bevel gear ring 402, driving the other bevel gear 401 to rotate synchronously. The bevel gear 401 drives the lead screw 403 fixed at one end to rotate. The lead screw 403 drives the moving column 404 to move through the thread. The moving column 404 drives the fixed frame 405 fixed at one end to move synchronously. The fixed frame 405 drives the delivery wheel 6 rotatably connected to it to move, and also drives the fixed plate 406 fixed on one side to move synchronously, thereby realizing the adjustment of the clamping size of the cable core.

[0027] The base 3 has a cavity that moves with the bevel gear 401, bevel gear ring 402 and moving column 404. The moving column 404 is fixedly connected to the inner wall of the cavity. One end of the fixed plate 406 is fixedly connected to the contact plate 5. The outer wall of the fixed frame 405 is fixedly connected to the second piston rod 13 at the protruding position.

[0028] It should be noted that the base 3 has a cavity inside to allow the bevel gear 401, bevel gear ring 402 and moving column 404 to be installed and moved. The moving column 404 is limited and slidably engaged with the inner wall of the cavity. The end of the fixed plate 406 is fixedly connected to the contact plate 5. The protruding part of the outer wall of the fixed frame 405 is fixedly connected to the second piston rod 13, so that the movement of each structure is linked and coordinated synchronously.

[0029] The arc adjustment assembly includes a first oil tank 701 fixed to one side of the delivery wheel 6. A first piston rod 702 is slidably connected inside the first oil tank 701. A movable seat 703 is fixed to one end of the first piston rod 702. Multiple rotating plates 704 are hinged at equal angles to one end of the movable seat 703. A fixed block 705 is hinged to one side of the rotating plate 704. A push plate 706 is fixed to one side of the fixed block 705. The push plate 706 is movably connected to the arc plate 9.

[0030] It should be noted that the first piston rod 702 in the first oil tank 701 slides to limit the movement, which drives the movable seat 703 fixed at one end to move. The movable seat 703 drives multiple rotating plates 704 hinged at equal angles at one end to rotate synchronously. The rotating plates 704 drive the fixed block 705 hinged on one side to move. The fixed block 705 pushes the push plate 706 fixed on one side to move. The push plate 706 drives the arc plate 9 movably connected to it to adjust the curvature to adapt to cable cores of different thicknesses.

[0031] The push plate 706 has an arc-shaped cross section. A spring is provided between the push plate 706 and the fixed shaft 8. One end of the spring is fixedly connected to the outer wall of the fixed shaft 8, and the other end of the spring is fixedly connected to the inner wall of the push plate 706.

[0032] It should be noted that the push plate 706 has an arc-shaped cross section. A spring is provided between the push plate 706 and the fixed shaft 8. One end of the spring is fixed to the outer wall of the fixed shaft 8, and the other end is fixed to the inner wall of the push plate 706. The elastic reset and adaptive adjustment of the push plate 706 are achieved by the extension and contraction of the spring.

[0033] The first oil tank 701 and the second oil tank 14 are connected by a hose, and the movable seat 703 is slidably connected to the fixed shaft 8.

[0034] It should be noted that the first oil tank 701 and the second oil tank 14 are connected by a hose to realize the transmission of oil and pressure linkage. At the same time, the movable seat 703 is slidably engaged with the fixed shaft 8, so that the movable seat 703 can slide stably along the fixed shaft 8.

[0035] The cleaning assembly includes a turntable 101 fixed to one side of one of the delivery wheels 6 via a connecting shaft. A fixed rod 102 is eccentrically fixed to one end of the turntable 101. A movable frame 103 is slidably connected to the fixed rod 102. An elastic telescopic rod 104 is fixed to one side of the movable frame 103. One side of the elastic telescopic rod 104 is fixedly connected to a fixed frame 405. A connecting frame 105 is fixed to one side of the movable frame 103. A movable ring 106 is fixed to one side of the connecting frame 105. A rotating ring 107 is rotatably connected inside the movable ring 106. One end of the rotating ring 107 is fixedly connected to the cleaning wire 11.

[0036] It should be noted that the delivery wheel 6 drives the turntable 101 to rotate through the connecting shaft. The fixed rod 102 eccentrically set on the turntable 101 rotates accordingly and drives the moving frame 103 to move. The moving frame 103 reciprocates under the limiting and elastic cooperation of the elastic telescopic rod 104, and then drives the moving ring 106 to move through the connecting frame 105. The moving ring 106 then drives the internal rotating ring 107 to rotate. Finally, the rotating ring 107 drives the cleaning wire 11 to rotate synchronously, so as to realize the cleaning operation of the wrapped cable core.

[0037] The outer wall of the rotating ring 107 is fixed with a protrusion 108, and the moving ring 106 has a threaded groove that moves in conjunction with the protrusion 108.

[0038] It should be noted that the protrusion 108 fixed on the outer wall of the rotating ring 107 cooperates with the threaded groove on the moving ring 106. When the moving ring 106 moves axially, the protrusion 108 slides along the threaded groove, thereby driving the rotating ring 107 to generate rotational motion.

[0039] The fixed ring 12 is fixedly connected to the fixed seat 15, and the rotating ring 107 is limited to the fixed seat 15 in a rotating connection. The fixed seat 15 has a cavity that cooperates with the fixed plate 406 and the contact plate 5.

[0040] It should be noted that the fixed ring 12 is fixedly connected to the fixed seat 15, and the rotating ring 107 is in a limited rotational engagement with the fixed seat 15. At the same time, a cavity is provided on the fixed seat 15 to allow the fixed plate 406 and the contact plate 5 to move through.

[0041] The delivery wheel 6 is fixed with a motor at one end, the cleaning wire 11 is wrapped with an elastic abrasive bristle layer on its outer wall and is arranged at an angle toward the wire core, and the arc plate 9 is a metal sheet with elastic deformation capability.

[0042] It should be noted that the delivery wheel 6 is driven by a motor to rotate and thus transport the wire core. The elastic abrasive bristle layer wrapped on the outer wall of the cleaning wire 11 is arranged at an angle towards the wire core, which can adaptively fit the surface of the wire core for grinding and cleaning. The arc plate 9 is made of a metal sheet that can be elastically deformed and can adaptively adjust with the change of wire diameter, thereby adapting to cable cores of different thicknesses.

[0043] Working principle: When using the cable core coating and forming device for cable processing, the cable core is sequentially passed through the center of the base 3, mold 2, and fixed seat 15 set on one side of the main body 1, maintaining a linear motion. After the cable core passes through, the motor is started, which drives the bevel gear 401 to rotate. The rotation of the bevel gear 401 drives the bevel ring 402 meshing on one side to rotate, and the rotating bevel ring 402 drives another bevel gear 401 to rotate synchronously. The rotation of the bevel gear 401 drives the lead screw 403 fixed to it to rotate, and then the thread on the lead screw 403 drives the moving column 404 to move in the mold 2. The cavity is designed with a limit sliding mechanism. The movement of the moving column 404 drives the fixed frame 405 to move synchronously. As the delivery wheel 6 moves with the fixed frame 405, the multiple delivery wheels 6, which are symmetrically distributed in a staggered manner, clamp the cable core. When the cable passes through the middle of the delivery wheel 6, it can be straightened. The movement of the moving column 404 drives the fixed plate 406 fixed on one side to move. The movement of the fixed plate 406 drives the contact plate 5 to move synchronously, so that the covered cable core is clamped through the contact plate 5. The contact plate 5 has an outwardly convex arc cross section, which can adapt to cable cores of different thicknesses. It works with the delivery wheel 6 to achieve the centered clamping and stable delivery of the wire core. When the fixed frame 405 moves, it causes the second piston rod 13, which is fixed at the protruding position of the fixed frame 405, to slide within the second oil tank 14, so that the oil in the second oil tank 14 moves through the hose to the first oil tank 701, thereby pushing the first piston rod 702 to move out of the first oil tank 701. The movement of the first piston rod 702 causes the movable seat 703, which is fixed to it, to move on the outer wall of the fixed shaft 8. When the movable seat 703 moves, it causes the multiple rotating plates 704, which are hinged to it at equal angles, to rotate, thereby allowing the oil to flow through the hose. The rotating plate 704 drives the fixed block 705, which is hinged to it, to move towards the outer wall of the delivery wheel 6. The movement of the fixed block 705 pushes the push plate 706 to move synchronously. When the push plate 706 moves, the spring fixed between it and the fixed shaft 8 is stretched. The spring drives the push plate 706 to return to its original position, so that the arc plate 9 connected to the push plate 706 is resisted and undergoes elastic deformation. Thus, when the vertical distance between the two delivery wheels 6 changes, the arc plate 9 changes its curvature synchronously to adapt to cable cores of different thicknesses. The motor on one side of the delivery wheel 6 is started, driving the delivery wheel 6 to rotate, thereby delivering the cable core. The molten material is pushed into the die head by the screw and extruded through the annular gap between the die core and the die sleeve of the die 2, forming a continuous tubular coating layer. Under pressure, the molten material tightly adheres to the surface of the preheated cable core, forming a dense insulation or sheath layer. When the delivery wheel 6 rotates, it drives the turntable 101 to rotate synchronously through the connecting shaft. The rotation of the turntable 101 drives the fixed rod 102, which is eccentrically fixed to one end of it, to rotate. Since the moving frame 103 is fixed to one side of the fixed frame 405 through the elastic telescopic rod 104, the rotating fixed rod 102 drives the moving frame 103 to reciprocate on one side of the fixed frame 405. When the fixed frame 405 reciprocates, the fixed frame 103 is fixed. The rod 102 slides within the movable frame 103, causing the elastic telescopic rod 104 to be stretched or compressed. The movement of the movable frame 103 drives the fixed connecting frame 105 to move, which in turn drives the movable ring 106, fixed to the connecting frame 105, to move within the fixed seat 15. Since the rotating ring 107 is limited and rotatably connected to the fixed seat 15, the movable ring 106 has a threaded groove that engages with the protrusion 108. The protrusion 108 is fixed to the outer wall of the rotating ring 107, allowing the movable ring 106 to rotate, which in turn drives the cleaning wire 11, which is fixed at an equal angle to one side of the rotating ring 107, to rotate. Since the other end of the cleaning wire 11 is fixedly connected to the fixed ring 12, and the fixed ring 12 is fixedly connected to the fixed seat 15, the cleaning wire 11... The radially arranged elastic abrasive bristles wrapped around the outer wall are tilted towards the wire core. Each bristle has bending elasticity and adapts to the changes in the thickness of the wire core by bending and compressing. It always fits the outer wall of the wire core. The abrasive particles at the rotating bristle ends continuously scrape and polish the bumps, particles and burrs on the surface of the coating layer to complete the surface defect cleaning.
