Description

Technical Field

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

[0002] A cable is an electrical or signal transmission device, typically composed of several or groups of conductors. It is internally energized and externally insulated, used to transmit electrical (magnetic) energy and information, and to achieve electromagnetic energy conversion. It is widely used in urban underground power grids, power plant lead-out lines, internal power supply in industrial and mining enterprises, and underwater power transmission lines across rivers and seas. During cable manufacturing, a layer of polymer material with specific properties, such as plastic or rubber, is continuously and uniformly wrapped around the surface of the cable core, primarily serving as insulation or a sheath.

[0003] A cable core coating molding device for civilian cable production, with patent publication number CN120473257A, mainly includes an installation frame, an extrusion assembly, a cooling assembly, and a pretreatment assembly. The pretreatment assembly is used to heat and clean the cable core wire, and the cable core wire passes through the extrusion cylinder of the extrusion assembly and is coated inside the extrusion cylinder. After the treatment, the cable core wire is cooled by the cooling assembly.

[0004] Although the above-mentioned device can achieve the coating and cooling treatment of cable cores, the cable cores are in a horizontal state during the movement process. After the coating treatment is carried out by the extrusion cylinder, the coating material on the cable core wire will shift towards the bottom of the cable core due to gravity and other factors. After cooling and forming, an uneven cable coating layer is formed, which affects the quality of the coating layer and the subsequent protective insulation effect.

[0005] Based on this, the present invention designs a cable core covering molding equipment to solve the above problems. Summary of the Invention

[0054] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] Example 1: Please refer to the accompanying drawings. This invention provides a technical solution:

[0056] A cable core coating molding equipment, such as Figure 1 , Figure 2 As shown, it includes a workbench 100 and support frames 103 symmetrically fixed on both sides of the top surface of the workbench 100. The top ends of the two support frames 103 are jointly fixed with a top plate 200, and the top plate 200 is provided with a covering component.

[0057] The top of the workbench 100 is uniformly provided with multiple extrusion cooling mechanisms arranged in a row, and a circular cooling water tank 101 is provided on the workbench 100 corresponding to the position of each extrusion cooling mechanism. A vertical central pipe 102 is fixed at the bottom center of the cooling water tank 101.

[0058] like Figure 6 As shown, the extrusion cooling mechanism includes a rotating seat 300 rotatably connected to the top of the cooling water tank 101, and multiple rotating seats 300 have a common rotating component connected to one side. Multiple movable extrusion components are evenly arranged along the circumferential direction on the top of the rotating seat 300, and each movable extrusion component is connected to a cooling water pipe 500. Figure 3 As shown, the bottom end of the cooling water pipe 500 passes through the rotating seat 300 and is connected to the piston assembly. The bottom of the piston assembly is connected to the water inlet pipe 502, and the bottom end of the water inlet pipe 502 is close to the bottom of the cooling water tank 101. The inner side wall of the cooling water tank 101 is provided with a fixed toothed ring 109, and the end of the piston assembly is correspondingly connected to the fixed toothed ring 109.

[0059] Each movable extrusion assembly is provided with an elastic pushing assembly on its outer side. A lifting adjustment assembly is provided on both support frames 103, and the lifting adjustment assembly is connected to the top of the multiple elastic pushing assemblies.

[0060] A central hole 302 is provided at the center of the rotating seat 300. The top end of the central tube 102 passes through and extends out of the central hole 302, so that the cable core can pass vertically through the rotating seat 300 and the central tube 102. A moving groove 304 is provided on the rotating seat 300 along the radial direction corresponding to the position of each movable extrusion assembly, so as to provide guidance and moving space for the movable extrusion assembly.

[0061] During the sheathing process of the cable core, the combination of the external unwinding device and the winding device allows multiple cable cores to pass vertically through the inside of the equipment and be located at their respective extrusion and cooling mechanisms.

[0062] The cable core moves intermittently and passes through the sheathing assembly, allowing the molten sheathing material to evenly coat the surface of the cable core. Then it moves to the corresponding extrusion and cooling mechanism. During the pause in the movement of the cable core, the lifting adjustment assembly moves multiple elastic pushing components on each rotating seat 300 and adjusts the position of the movable extrusion assembly, so that multiple movable extrusion assemblies on the same rotating seat 300 simultaneously contact the sheathing layer of the cable core.

[0063] Then, the rotating assembly rotates the rotating seat 300. During the rotation, the moving extrusion assembly extrudes the cable core wire sheath, making the cable core sheath thickness more uniform and the sheath material more tightly attached to the cable core wire. At the same time, the fixed toothed ring 109 causes the piston assembly to move, drawing cooling water from the cooling water tank 101 into the moving extrusion assembly through the cooling water pipe 500. This cools the sheath while it is being extruded, improving the sheath forming effect.

[0064] After the extrusion cooling molding is completed, the lifting adjustment component moves upward and disengages from the elastic pushing component, thereby causing the elastic pushing component and the movable extrusion component to return to their original positions and disengage from the cable core wire. This allows the cable core wire to move again under the action of the winding and unwinding devices and pass through the central tube 102. The cable core wire stops moving once every certain distance and repeats the above process to perform segment-by-segment extrusion cooling molding of the cable core wire.

[0065] After the cooling water enters the moving extrusion assembly through the piston assembly for cooling, it is discharged from the moving extrusion assembly and returns to the cooling water tank 101, so that the water in the cooling water tank 101 can be circulated repeatedly. In order to ensure the cooling effect of the cooling water, a structure with cooling or refrigeration function can be set in the cooling water tank 101 to prevent the cooling water temperature from becoming too high after multiple cycles, which would affect the subsequent cooling effect.

[0066] Among them, such as Figure 6 As shown, the movable extrusion assembly includes a limiting guide frame 303 fixed to the top of the rotating seat 300 and a spring frame 604 connected to the limiting guide frame 303 by a spring. The middle part of the spring frame 604 is vertically arranged, and the top and bottom are horizontally arranged. The two horizontal ends pass through the limiting guide frame 303 and are rotatably connected to a vertical roller 601. The bottom end of the roller 601 passes through the moving groove 304 and extends into the cooling water tank 101.

[0067] like Figure 10 As shown, a cooling pressure roller 600 is fixed on the outer side of the roller shaft 601. The top and bottom ends of the roller shaft 601 are respectively provided with an upper cavity and a lower cavity. The side walls of the upper cavity and the lower cavity are provided with multiple through holes, which are connected to the inner cavity of the cooling pressure roller 600. One end of the cooling water pipe 500 extends into the upper cavity of the roller shaft 601, and a flow-limiting structure is provided in the lower cavity of the roller shaft 601. The bottom end of the flow-limiting structure extends out of the roller shaft 601.

[0068] When the cable core and sheathing layer move down to the cooling roller 600, the movement is paused. Then, through the action of the lifting adjustment component and the elastic pushing component, the spring frame 604 compresses the spring and drives the cooling roller 600 to move towards the cable core and contact the sheathing layer of the cable core. The rotating component causes the rotating seat 300 to drive the multiple cooling rollers 600 on it to rotate. During the rotation, the cooling roller 600 squeezes the sheathing layer. At the same time, through the action of the piston component and other structures, the cooling water in the cooling water tank 101 enters the cooling roller 600 to cool the cooling roller 600 and the contacting sheathing layer, thereby realizing the extrusion cooling molding process of the cable core sheathing layer.

[0069] After the cooling water enters the cooling roller 600, the water pressure causes the flow-limiting structure to move and open the bottom of the cooling roller 600 so that the cooling water can return to the cooling water tank 101. When the piston assembly stops moving, the flow-limiting structure returns to its original position and closes the cooling roller 600 to prevent the cooling water inside the cooling roller 600 from being discharged when there is no cooling water input.

[0070] like Figure 12 As shown, multiple horizontal first partitions 602 are uniformly fixed in the vertical direction in the inner cavity of the cooling roller 600. A horizontal second partition 603 is fixed between two adjacent first partitions 602. Multiple through holes are provided on the first partitions 602 near the outer edge and on the second partition 603 near the inner edge. As the cooling water enters the cooling roller 600 and flows downward, the movement path of the cooling water in the cooling roller 600 is increased by the restriction of the first partitions 602 and the second partitions 603, so as to fully cool the cooling roller 600 and improve the cooling effect.

[0071] like Figure 11 As shown, a sealing ring platform 509 is fixed on the outer wall of the section of the cooling water pipe 500 located in the upper cavity of the roller shaft 601. The circumferential side of the sealing ring platform 509 contacts the inner wall of the upper cavity of the roller shaft 601 through a sealing ring, which improves the sealing performance of the cooling pressure roller 600 and the roller shaft 601 when they rotate relative to the cooling water pipe 500, and prevents the cooling water from leaking out from the top of the upper cavity of the roller shaft 601.

[0072] Among them, such as Figure 7As shown, the elastic pushing assembly includes a pushing wheel 400 and rotating rods 401 rotatably connected to both ends of the pushing wheel 400. The pushing wheel 400 contacts the outer surface of the spring frame 604. The two rotating rods 401 are arranged in parallel and inclined relative to the top surface of the rotating seat 300. The bottom end is rotatably connected to the top surface of the rotating seat 300, and a torsion spring is provided at the rotatable connection. A pressure groove 402 is provided on the rotating rod 401 along the length direction. A pressure wheel 403 is provided in the pressure groove 402. A connecting shaft 404 is connected to the center of the two pressure wheels 403. A vertical lifting column 405 is rotatably connected to both ends of the connecting shaft 404. A ball bearing 407 is provided at the top of the lifting column 405. The bottom end is connected to the top surface of the rotating seat 300 through a spring. A vertical limiting shaft 406 is slidably connected inside the lifting column 405. The bottom ends of the two limiting shafts 406 extend out of the lifting column 405 and are fixedly connected to the top surface of the rotating seat 300.

[0073] When the lifting adjustment assembly presses down on the lifting column 405, the lifting column 405 drives the connecting shaft 404 and the pressure roller 403 to move down. Through the action of the pressure groove 402, the rotating rod 401 rotates and drives the push wheel 400 to move. This causes the push wheel 400 to push the spring frame 604 and the cooling pressure roller 600 on the spring frame 604 to move towards the center of the rotating seat 300 and contact the cable core. During the rotation, the sheathing layer on the cable core is pressurized and cooled to form. The top of the lifting column 405 is provided with a ball bearing 407. The ball bearing 407 contacts the lifting adjustment assembly so that the top of the lifting column 405 can move flexibly relative to the lifting adjustment assembly.

[0074] After the extrusion operation on the upper section of the cable is completed, the lifting and adjusting assembly moves upward, and the lifting column 405, rotating rod 401, and spring frame 604 return to their original positions under the action of the spring, driving the cooling pressure roller 600 to move outward and disengage from the cable core wire so that the cable core wire can continue to move.

[0075] Among them, such as Figure 1 , Figure 3 As shown, the lifting adjustment assembly includes vertical lifting hydraulic rods 104 symmetrically fixed on two support frames 103. The bottom ends of the two lifting hydraulic rods 104 are jointly fixed with a lifting frame, and an annular adjusting pressure plate 105 is fixed on the lifting frame corresponding to the position of each rotating seat 300. The top ends of multiple lifting columns 405 on the same rotating seat 300 are all located below the corresponding adjusting pressure plate 105.

[0076] When it is necessary to adjust the position of structures such as the push wheel 400 and the cooling pressure roller 600, the lifting hydraulic rod 104 drives the lifting frame and the adjusting pressure plate 105 to move downward. By adjusting the contact between the pressure plate 105 and the top of the lifting column 405, the lifting column 405 moves downward, thereby causing the elastic push assembly to move and adjusting the position of the cooling pressure roller 600. When the rotating seat 300 and the lifting column 405 rotate, the top of the lifting column 405 contacts the bottom surface of the adjusting pressure plate 105 through the ball bearing 407, reducing contact friction during movement and improving movement flexibility.

[0077] Among them, such as Figure 13 As shown, the flow-limiting structure includes an annular baffle 605 fixed in the lower cavity of the roller 601. The bottom of the annular baffle 605 is a conical surface, and a corresponding sealing plug 606 is provided at the bottom. A vertical spring shaft 607 is fixed at the bottom center of the sealing plug 606. A spring plate 608 is fixed at the bottom end of the spring shaft 607. A spring is connected between the spring plate 608 and the bottom end of the lower cavity of the roller 601. A vertical spring tube 609 is fixed at the bottom center of the spring plate 608. Multiple through slots are provided on the spring plate 608 corresponding to the inner side of the spring tube 609, and the bottom end of the spring tube 609 passes through and extends out of the roller 601.

[0078] After the cooling water is delivered into the cooling roller 600 by the piston assembly, the water pressure causes the sealing plug 606 and the spring plate 608 to compress the spring and move downward, allowing the cooling water to be discharged through the through groove on the spring plate 608 and the spring tube 609, returning to the cooling water tank 101. When the piston assembly stops moving, there is no cooling water input into the cooling roller 600, the pressure on the sealing plug 606 decreases, and the sealing plug 606 moves upward under the action of the spring and other structures, contacting the annular baffle 605, sealing the bottom of the roller 601, and restricting the outflow of cooling water from the cooling roller 600.

[0079] Among them, such as Figure 8 , Figure 9 As shown, the piston assembly includes a piston box 501 fixed to the bottom of the rotating seat 300. Cooling water pipe 500 and water inlet pipe 502 are respectively connected to the top and bottom of the inner end of the piston box 501. Both cooling water pipe 500 and water inlet pipe 502 are equipped with one-way valves, so that water in the cooling water tank 101 can only enter the piston box 501 along the water inlet pipe 502 and then be discharged from the piston box 501 into the cooling water pipe 500. A piston plate 503 is slidably connected in the piston box 501. One side of the piston plate 503 is connected to the inner wall of the piston box 501 by a spring, and a piston rod 504 is fixed in the middle.

[0080] One end of the piston rod 504 extends out of the piston box 501 and is fixed with a reciprocating rod 505. The reciprocating rod 505 has a straight groove, and a rotating disk 506 is located below it. The rotating disk 506 is rotatably connected to one end of the piston box 501. A vertical reciprocating shaft 507 is eccentrically located at the top and is situated within the straight groove of the reciprocating rod 505. Figure 5 As shown, a transmission gear 508 is fixed at the bottom of the rotating disk 506, and the transmission gear 508 meshes with the fixed gear ring 109.

[0081] During the rotation of the rotating seat 300, the piston box 501 moves accordingly. During this movement, the transmission gear 508 rotates through the fixed gear ring 109, which in turn causes the rotating disk 506 to drive the reciprocating shaft 507 to rotate. The reciprocating shaft 507 drives the reciprocating rod 505, piston rod 504, and piston plate 503 to reciprocate through the straight groove. Thus, through the action of the piston, the water in the cooling water tank 101 enters the piston box 501 through the water inlet pipe 502, and then flows from the piston box 501 into the cooling water pipe 500, and then into the cooling pressure roller 600 to cool and reduce the temperature of the cooling pressure roller 600.

[0082] Example 2: The structure of this example is basically the same as that of Example 1, except that, as shown in Example 2... Figure 1 As shown, the coating assembly includes multiple collecting cylinders 206 uniformly fixed on the top plate 200. The positions of the collecting cylinders 206 correspond one-to-one with the positions of the central tube 102, and the upper sides of the multiple collecting cylinders 206 are connected to a conveying pipe 205 through connecting pipes. A circular hole is provided at the center of the top end of each collecting cylinder 206, and a threaded pipe is provided at the center of the bottom end. The bottom surface of the inner cavity of the collecting cylinder 206 is inclined towards the threaded pipe, and a coating pipe 207 is threadedly connected to the outer side of the threaded pipe. Figure 3 , Figure 4 As shown, the upper part of the covered tube 207 is provided with a threaded hole that mates with the threaded tube, and the lower part is provided with a stepped hole. The upper diameter of the stepped hole is the same as the inner diameter of the threaded tube, and the lower diameter is smaller than the upper diameter. The bottom end of the upper hole is a conical surface and is inclined towards the lower hole.

[0083] When the cable core passes vertically through the collecting cylinder 206 and the covering tube 207, the molten insulating covering material enters the conveying pipe 205 through the external conveying device and enters the corresponding collecting cylinder 206 through each connecting pipe. When the cable core passes through the collecting cylinder 206, the covering material inside it adheres to the surface of the cable core. After entering the covering tube 207, the covering material of the cable core is initially squeezed through the stepped holes with gradually decreasing radius, making the covering tighter. The covering tube 207 can be removed by twisting and replaced with a covering tube 207 of different hole diameters to adapt to different cable cores.

[0084] Example 3: The structure of this example is basically the same as that of Example 1, except that, as shown in Example 3... Figure 1 As shown, the rotating assembly includes worm gears 301 fixed to the outside of the rotating seat 300. Multiple worm gears 301 mesh with a worm 106 on one side. The worm 106 is rotatably connected to the top surface of the worktable 100, and one end is connected to a first pulley 107. A slot is provided on the worktable 100 corresponding to the position of the first pulley 107, such as... Figure 2 As shown, a second pulley 108 is provided below the slot. The first pulley 107 and the second pulley 108 are connected by a transmission belt. A motor is connected to one side of the second pulley 108. The motor is fixed to the bottom of the workbench 100 and is offset from the position of the cooling water tank 101.

[0085] When it is necessary to rotate the rotating seat 300 and its cooling roller 600 and other structures, the worm gear 106 is rotated by the drive of the motor and the transmission of the first pulley 107 and the second pulley 108, which in turn causes the multiple worm wheels 301 to drive the corresponding rotating seat 300 to rotate, and the cable core wire is cooled and extruded by the rotating cooling roller 600.

[0086] Example 4: The structure of this example is basically the same as that of Example 1, except that, as shown in Example 4... Figure 14 As shown, the cooling water pipe 500 includes a fixed vertical section 500a fixedly connected to the rotating seat 300, a movable vertical section 500c rotatably connected to the top center of the roller shaft 601, and a curved connecting section 500b connecting the top ends of the fixed vertical section 500a and the movable vertical section 500c. The curved connecting section 500b is a flexible hose. The middle part of the movable vertical section 500c is fixedly connected to the top of the spring frame 604 through a movable section limiting bracket 500d, which restricts the movement of the water pipe. The position of the movable vertical section 500c allows the cooling roller 600 and roller shaft 601 to rotate relative to the movable vertical section 500c during operation. By setting the curved connecting section 500b as a flexible hose, the movable vertical section 500c can move along with the cooling roller 600 when its position is adjusted in the radial direction relative to the rotating seat 300. The curved connecting section 500b can withstand a certain degree of deformation and maintain the connection between the movable vertical section 500c and the fixed vertical section 500a, ensuring the smooth delivery of cooling water.

[0087] Example 5: The structure of this example is basically the same as that of Example 1, except that, as shown in Example 5... Figure 1As shown, the top plate 200 has symmetrical and parallel adjusting hydraulic rods 201 on both sides of the top. One end of the adjusting hydraulic rod 201 is fixed with an adjusting block 202. The bottom end of the adjusting block 202 is slidably connected to the top surface of the top plate 200. A horizontal guide roller 203 is rotatably connected between the tops of the two adjusting blocks 202. Multiple limiting ring grooves 204 are evenly provided on the guide roller 203, and the positions of the limiting ring grooves 204 correspond one-to-one with the positions of the central tube 102.

[0088] When the cable core enters the collecting cylinder 206, the position of the guide roller 203 is adjusted by adjusting the hydraulic rod 201 and the adjusting block 202 so that the cable core unwound at a horizontal or inclined angle can be located in the corresponding limiting ring groove 204. After the position is adjusted by the guide roller 203, it is vertically located at the center of the central tube 102 for subsequent coating and extrusion molding.
