Description

Technical Field

[0001] This invention relates to the field of power cable manufacturing technology, and more particularly to a cross-linking device for the insulation production of power cables. Background Technology As the core carrier of electrical energy transmission, the insulation layer of power cables directly determines the insulation performance, operational stability, and service life of the cables. During the production process of power cable insulation, the insulation layer must be tightly and uniformly wrapped around the conductor surface, while meeting key technical requirements such as thickness consistency and strong bonding with the conductor, in order to avoid safety hazards such as leakage and breakdown caused by insulation defects during operation.

[0002] In practical applications, existing cross-linking equipment for power cable insulation production has gradually revealed several technical limitations: Firstly, the linkage control accuracy between cable transmission speed and extruder output is insufficient. Most devices rely on screw speed to indirectly adjust the extrusion amount. This method has a lag in response. When the cable transmission speed fluctuates, it can easily lead to the insulation layer being too thick or too thin, affecting the stability of insulation performance. Secondly, the bonding strength between the conductor and the insulation material is insufficient. In traditional production, the bonding is achieved solely by the natural adhesion of the melted material. Under conditions of cable bending, stretching, or long-term thermal expansion and contraction, the insulation layer is prone to detachment and slippage from the conductor surface, reducing the structural stability of the cable. Third, the concentricity detection and abnormal handling mechanism is imperfect. When the cable conductor deviates from the center of the extruder die, the existing devices mostly only issue an alarm or make passive fine adjustments, which cannot stop the cable transmission and material extrusion in time, resulting in a batch of unqualified products, increasing material waste and production costs. Fourth, there are oversights in the quality inspection process. Most devices only perform single inspections on the insulation layer thickness, making it difficult to simultaneously check for debonding issues between the insulation layer and the conductor. This can easily lead to products with hidden defects entering the market, creating operational risks. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cross-linking device for the production of insulation in power cables.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A cross-linking device for producing insulation of power cables includes a base, on both sides of the top of the base, conveying rollers for transmitting cables are fixedly provided, and between the two sets of conveying rollers, from left to right, are a moving speed detection mechanism for detecting the transmission speed of the cable, a welding machine and an anchoring mechanism for increasing the connection strength between the cable surface and the material, an extruder mechanism for extruding the material and connecting it to the cable surface, a center detection mechanism for detecting whether the center of the cable coincides with the center of the extruder die, a thickness detection mechanism for detecting whether the thickness of the material wrapped on the cable surface is uneven, and a material integrity detection mechanism for detecting whether the material on the cable surface has fallen off.

[0013] The present invention has the following beneficial effects: This device captures the cable transmission speed signal in real time through a moving speed detection mechanism, and directly controls the valve opening of the extruder mechanism to adjust the output rate—reducing the output when the speed slows down and increasing the output when the speed speeds up. Compared with the existing method that relies on screw speed adjustment, the response is more direct and the adaptation is more precise, effectively avoiding the problem of excessively thick or thin insulation layer caused by mismatch between speed and output, and ensuring the consistency of insulation layer thickness.

[0014] This device adds a welding machine and an anchoring mechanism before the extrusion process. The welding machine firmly fixes the anchoring mechanism to the cable surface, forming a mechanical anchoring foundation. When the insulating material is coated by the extruder, the anchoring mechanism can physically interlock with the material. Combined with the material's own adhesion, this significantly improves the bonding strength between the insulation layer and the cable surface, effectively reducing the risk of insulation layer detachment or slippage due to bending or stretching during subsequent processing or operation, and extending the cable's service life.

[0015] This device, by incorporating a center detection mechanism, can monitor the relative position of the cable center and the extruder die center in real time. When a deviation is detected, it can quickly trigger an alarm and control the cable to stop transmission and the extruder to shut down. Compared to existing methods that only alarm or passively fine-tune, this design can terminate abnormal production at its source, avoid batches of defective products caused by persistent deviations, reduce material waste and rework costs, and improve the production pass rate.

[0016] After the insulation layer is formed, this device forms a dual detection closed loop by setting up a thickness detection mechanism and a material integrity detection mechanism. The thickness detection mechanism checks for problems with the uniformity of the insulation layer, while the material integrity detection mechanism simultaneously verifies the bonding state between the insulation layer and the cable surface. Compared with the existing single detection method, it realizes comprehensive monitoring of the insulation layer thickness and bonding firmness, effectively preventing defective products such as uneven thickness and hidden debonding from leaving the market, and ensuring the reliability of cable insulation performance.

[0020] 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.

[0021] The system includes a base 1, with conveyor rollers 2 fixed on both sides of the top of the base 1 for transmitting cables. Between the two sets of conveyor rollers 2, from left to right, are a moving speed detection mechanism 3 for detecting the transmission speed of the cable, a welding machine 4 for increasing the connection strength between the cable surface and the material, an anchoring mechanism 5, an extruder mechanism for extruding the material and connecting it to the cable surface, an extruder mechanism 6, a center detection mechanism 7 for detecting whether the center of the cable coincides with the center of the extruder die 65, a thickness detection mechanism 8 for detecting whether the thickness of the material wrapped on the cable surface is uneven, and a material integrity detection mechanism 9 for detecting whether the material on the cable surface has fallen off.

[0022] Before starting the device, complete the equipment debugging: According to the diameter of the cable to be processed, adjust the first electric push rod 32 of the moving speed detection mechanism 3 so that the three pressure rollers 34 are in contact with the cable surface to ensure smooth rotation; adjust the initial length of the elastic telescopic rod 721 of the center detection mechanism 7 so that the four pressure rollers 723 are on the same circumferential surface and the distance sensor 726 is set to zero; adjust the second electric push rod 81 of the thickness detection mechanism 8 so that the abutment roller 86 lightly touches the cable surface, set the preset threshold of each detection mechanism and the linkage logic of the controller, pass one end of the cable to be processed through the left conveyor roller 2, through the center of the positioning frame 31 of the moving speed detection mechanism 3, the working area of ​​the welding machine 4, the extruder die head 65, the detection frame 71 of the center detection mechanism 7, the abutment roller 86 of the thickness detection mechanism 8, and the fixing frame 91 of the material integrity detection mechanism 9, and finally be clamped and fixed by the right conveyor roller 2. Start the drive motor of the conveyor roller 2, and the cable is transmitted at a stable speed along the length direction of the base 1.

[0023] The moving speed detection mechanism 3 includes a positioning frame 31, a first electric push rod 32, a first C-shaped frame 33, a pressing roller 34, and a speed sensing component 35. The positioning frame 31 is fixedly connected to the top of the base 1. Multiple first electric push rods 32 are provided and are evenly arranged around the center of the cable along its circumference. The first electric push rods 32 are fixedly connected to the inner wall of the positioning frame 31, and the output end of the first electric push rod 32 is fixedly connected to the first C-shaped frame 33. Both ends of the pressing roller 34 are rotatably set to the two sides of the inner wall of the first C-shaped frame 33 through bearings. The speed sensing component 35 is fixedly connected to the output end of one of the first electric push rods 32.

[0024] The speed sensing component 35 includes a connecting slide plate 351, a fixing plate 352, a vertical plate 353, a rotating cam 354, a first switch 355, a first display screen 356, and a first alarm 357. The connecting slide plate 351 is fixedly connected to the top of one of the first C-shaped frames 33. The fixing plate 352 is fixedly connected to the inner wall of the positioning frame 31, and a sliding groove for the connecting slide plate 351 to slide through the inside of the fixing plate 352. The vertical plate 353 is fixedly connected to the bottom of the connecting slide plate 351. The rotating cam 354 is rotatably connected to one side of the outer wall of the vertical plate 353 through a bearing, and the rotating cam 354 is fixedly connected to the rotating shaft of the pressure roller 34. The first switch 355, the first display screen 356, and the first alarm 357 are all fixedly connected to one side of the outer wall of the vertical plate 353.

[0025] The moving speed detection mechanism 3 starts synchronously, and the pressure roller 34 rotates with the cable transmission, driving the rotating cam 354 to periodically trigger the first switch 355. The speed data is displayed in real time on the first display screen 356. If the speed exceeds the preset range, for example, the normal conveying range is within 50-100. If it is greater than 100, it means the speed is too fast, and if it is less than 50, it means the speed is too slow. Both can activate the first alarm 357, which will immediately issue a warning.

[0026] The anchoring mechanism 5 is provided in multiple sets. The anchoring mechanism 5 includes an elastic protrusion 51 and a connecting rod 52. The bottom of the connecting rod 52 is fixedly connected to the surface of the cable, and the top of the connecting rod 52 is fixedly connected to the elastic protrusion 51. Multiple irregular guide grooves are passed through the inside of the connecting rod 52. A return spring is fixedly provided between the two sides of the inner wall of the elastic protrusion 51 in a vertical direction.

[0027] During normal cable transport, welding machine 4 starts, and the robotic arm drives the welding head to move, welding and fixing the connecting rods 52 of the anchoring mechanism 5 one by one to the cable surface. The welding points are evenly distributed along the length of the cable, forming a continuous anchoring array. The anchoring mechanism 5 enhances the bonding strength through "mechanical anchoring + material guidance": welding machine 4 fixes the connecting rods 52 to the cable surface to form a rigid connection base. The hollow structure of the elastic protrusion 51 and the internal return spring give it elastic deformation capability, which can adaptively shrink with pressure when the material is wrapped, increasing the contact area with the material. The irregular guide groove in the connecting rod 52 can guide the molten material to fill the gap between the anchoring structure and the cable, so that the material and the anchoring mechanism 5 form a physical interlock. Combined with the material's own viscosity, it greatly improves the bonding firmness between the insulation layer and the cable. Based on this structural design, when the molten material is wrapped by the inner cavity of the die head 65, it can fully fill the gaps of the anchoring structure through the guide groove. The elastic protrusion 51 shrinks under the material pressure and is compacted by the spring rebound, ultimately ensuring that the material and the cable surface form a tight and firm bond.

[0028] The extruder mechanism 6 includes a material tank 61, a spiral conveying pipe 62, a connecting pipe 63, a valve 64, and a die head 65. Support legs are fixedly provided on both sides of the material tank 61, and the bottom of the support legs is fixedly connected to the base 1. The spiral conveying pipe 62 is fixedly connected to the bottom discharge port of the material tank 61. The connecting pipe 63 is fixedly connected to the bottom discharge port of the spiral conveying pipe 62. The inside of the connecting pipe 63 is fixedly connected to the valve 64, and the outlet of the connecting pipe 63 is fixedly connected to the die head 65. The die head 65 has a through hole for a cable to pass through, and the bottom of the die head 65 is fixedly connected to the top of the base 1.

[0029] The extruder mechanism 6 starts, and the insulating material in the material bucket 61, after being pre-mixed by stirring, is conveyed to the connecting pipe 63 by the spiral conveyor pipe 62. The controller automatically adjusts the opening of the valve 64 in the connecting pipe 63 according to the real-time speed signal transmitted by the moving speed detection mechanism 3: when the cable speed is detected to increase, the valve 64 opening increases, increasing the material output; when the speed decreases, the valve 64 opening decreases, reducing the material output.

[0030] The center detection mechanism 7 includes a detection frame 71 and a detection component 72. The detection component 72 includes an elastic telescopic rod 721, a second C-shaped frame 722, a pressure roller 723, an extension plate 724, a reference plate 725, a distance sensor 726, a second display screen 727, and a second alarm 728. The detection frame 71 is fixedly connected to the top of the base 1. Multiple detection components 72 are provided and are evenly arranged around the center of the cable along its circumference and fixedly connected to the inner wall of the detection frame 71. The elastic telescopic rod 721 is fixedly connected to the inner wall of the detection frame 71, and the output end of the elastic telescopic rod 721 is fixedly connected to the second C-shaped frame 722. Both ends of the pressure roller 723 are rotatably connected to the two sides of the inner wall of the second C-shaped frame 722 through bearings. The extension plate 724 is fixedly connected to the top of the second C-shaped frame 722. The reference plate 725 is fixedly connected to one side of the outer wall of the detection frame 71. The distance sensor 726, the second display screen 727, and the second alarm 728 are all fixedly connected to one side of the outer wall of the reference plate 725.

[0031] After being coated with material, the cable enters the center detection mechanism 7. Four pressure rollers 723, under the action of the elastic telescopic rod 721, adhere to the cable surface. The distance sensor 726 detects the distance between the extension plate 724 and the control plate 725 in real time and transmits the data. The controller compares the four distance values. If the difference exceeds the preset range, the second alarm 728 is immediately triggered to issue a warning, and simultaneously, control commands are issued: the left and right conveyor rollers 2 stop rotating, cable transmission is terminated; the valve 64 of the extruder mechanism 6 closes, material output stops, and the eccentricity is prevented from causing a batch of defective products. After the staff investigates and corrects the eccentricity problem, the equipment can be restarted.

[0032] The thickness detection mechanism 8 includes a second electric push rod 81, a C-shaped plate 82, a fixed cylinder 83, an undulating rod 84, a third C-shaped frame 85, an abutting roller 86, a protruding plate 87, and a height sensor 88. The second electric push rod 81 is fixedly connected to the top of the base 1, and its output end is fixedly connected to one side of the outer wall of the C-shaped plate 82. There are two fixed cylinders 83, which are symmetrically arranged on both sides of the inner wall of the C-shaped plate 82 and fixedly connected to the inner wall of the C-shaped plate 82. The undulating rod 84 is slidably arranged inside the fixed cylinder 83 through an elastic element and extends out of the fixed cylinder 83. The bottom of the undulating rod 84 is fixedly connected to the third C-shaped frame 85, and both ends of the abutting roller 86 are rotatably connected to both sides of the inner wall of the third C-shaped frame 85 through bearings. The protruding plate 87 is fixedly connected to one side wall of the third C-shaped frame 85. There are two height sensors 88, which are symmetrically arranged on both sides of the inner wall of the C-shaped plate 82 and fixedly connected to the inner wall of the C-shaped plate 82.

[0033] Cables that pass the center detection continue to be transmitted. After entering the thickness detection mechanism 8, the abutment roller 86 moves the undulation rod 84 along with the surface of the insulation layer, and the protruding plate 87 moves synchronously. The height sensor 88 captures the displacement signal and converts it into thickness data. If the thickness difference exceeds the preset range, the corresponding alarm is triggered. For example, if the normal thickness value is 10-20, the second alarm 728 will be triggered if the undulation is less than 10 or more than 20.

[0034] The material integrity testing mechanism 9 includes a fixed frame 91 and integrity testing components 92. The bottom of the fixed frame 91 is fixedly connected to the top of the base 1, and a hole for cable extension is passed through it. The integrity testing components 92 are provided in multiples and are evenly arranged around the center of the cable along its circumference and are fixedly connected to one side of the outer wall of the fixed frame 91.

[0035] The integrity inspection component 92 includes a horizontal plate 921, a probe 922, a display rod 923, a contact head 924, an arc plate 925, a sliding plate 926, and a third switch 927. The horizontal plate 921 is fixedly connected to one side of the outer wall of the fixed frame 91. One end of the probe 922 is rotatably connected to one side of the outer wall of the horizontal plate 921 through a bearing and a torsion spring. The display rod 923 is fixedly connected to one end of the probe 922. The contact head 924 is fixedly connected to one side of the outer wall of the display rod 923. The arc plate 925 is fixedly connected to one side of the outer wall of the horizontal plate 921. Multiple sliding plates 926 are provided. The arc plate 925 has a groove for the sliding plate 926 to slide. The third switch 927 is fixedly connected to one side of the outer wall of the sliding plate 926.

[0036] The cable then enters the material integrity detection mechanism 9. Multiple probes 922 are attached to the surface of the insulation layer from different directions via torsion springs. When a detachment or bulge occurs, the probe 922 deflects, causing the contact 924 on the display rod 923 to trigger the third switch 927. The controller activates an alarm signal. The position of the third switch 927 can be adjusted according to specific values. For example, if a 10-degree rotation of the probe 922 indicates a problem, the position of the third switch 927 can be adjusted so that the angle between the third switch 927 and the contact 924 is 10 degrees. This adjustment can be made according to different detection environments.

[0037] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
