TECHNICAL FIELD
[0001] The utility model relates to copper wire shielded cable production technical field especially is a distribution board. BACKGROUND
[0002] Under the development trend of diversified and high-density distribution of power grid construction, copper wire shielded cables carrying larger fault short-circuit current are more and more widely used. The role of copper wire shielding is to balance the magnetic field and limit the electric field, so that the direction of the electric field is consistent with the direction of the insulation radius, which requires the copper wire to be evenly and neatly arranged on the cable insulation core.
[0003] The existing method is to use a distribution disc. Before entering the threading die together with the cable insulation core, the copper wire passes through the threading hole provided on the distribution disc. Since the number of threading holes is an integer multiple of the number of copper wires, positioning through the threading hole can make the copper wire evenly and neatly arranged on the cable insulation core when entering the threading die together with the cable insulation core. When producing different types of shielded cables, only different distribution discs need to be replaced to ensure that the threading holes on the distribution disc correspond to the number of copper wires of the shielded cable to be produced. The existing distribution disc has a fixed number of holes, so during the production process of the copper wire shielding process of the wire and cable, multiple specifications (different number of threading holes) of distribution discs need to be prepared to adapt to different specifications of cables and different numbers of copper wires. This not only has high cost, but also requires additional purchase when producing new specifications of cables, which is slow.
[0004] With the trend of product customization, the number of copper wires is increasingly inconsistent, and each product has its specific design structure. In actual production process, equipment is constantly updated and replaced. The new equipment generally has electromagnetic wire feeding tension, and the tension of each copper wire can be visualized, adjustable and controllable. The copper wire can be better evenly arranged on the surface of the insulation core. However, with the development of the equipment industry, more and more production plants still use old equipment for production. The old equipment generally uses belt tension control, and the adjustment of tension is only controlled by hand feeling or experience, which cannot meet the requirements of fine production. If the existing old equipment needs to be updated to realize the visualization of tension, the whole stranding cage needs to be modified, which is basically the same as replacing new equipment, and the cost is very high.
[0005] The existing technology cannot monitor the tension of the copper wire and cannot meet the use scenarios of different numbers of copper wires. UTILITY MODEL CONTENTS

[0039] The utility model will be further described below in combination with the drawings and specific embodiments, so that those skilled in the art can better understand the utility model and can be implemented, but the embodiments are not as the limitation of the utility model.
[0040] It should be noted that the distribution disc 100 is located at the front side of the center pipe of the stranding cage 600, and the distribution disc 100 is located at the rear side of the sizing die 700.
[0041] The distribution plate is installed at the front end of the center pipe of the stranding cage of the metal wire shielding process production equipment (for example, a cage stranding machine, a frame stranding machine, etc.), and is mainly used for regularly arranging the copper wires that are drawn out of the stranding cage. It is mainly used in the metal wire shielding process (such as copper wire shielding, aluminum wire shielding, and steel wire armor). In the production process, it is necessary to ensure that the copper wires drawn out can be uniformly and regularly arranged on the insulating cable core after passing through the distribution plate. Firstly, the consistency of the tension of each copper wire is ensured; secondly, after being distributed and arranged by the distribution plate, the multiple copper wires can be evenly distributed for 360°, so as to ensure the production quality. The stranding cage in the comparative example generally has tension, and the common old stranding cage generally uses belt tension, which can manually adjust the tension, but cannot display the tension value in real time. Each stranding cage is adjusted independently, and the tension of each copper wire cannot be ensured to be consistent.
[0042] In order to solve the above problems, with reference to Figures 1-8 The utility model discloses a distribution plate, which comprises:
[0043] A distribution disc 100;
[0044] A plurality of wire passing modules 200 are connected on the distribution disc 100 at equal intervals along the circumference of the distribution disc 100; the wire passing modules 200 extend in the X direction; the wire passing modules 200 comprise a main body 210, a pressure sensor 220, a wire passing module 230 and an elastic member 240; the main body 210 is provided with a mounting chamber 211; along the X direction, the pressure sensor 220 is connected in the mounting chamber 211 at one end close to the distribution disc 100; the wire passing module 230 is arranged at one side of the pressure sensor 220, and the wire passing module 230 reciprocates in the X direction in the mounting chamber 211; the wire passing module 230 is provided with a wire passing hole 231 for the copper wire 400 to pass through. One end of the elastic member 240 is connected with the wire passing module 230, and the other end is in contact with the pressure sensor 220;
[0045] The PLC wireless control module 300 is electrically connected with the wire passing module 200;
[0046] A display screen (not shown in the figure) is electrically connected with the PLC wireless control module 300.
[0047] Specifically, a plurality of wire passing modules 200 are arranged in the embodiment, so that the same number of wire passing modules 200 can be selected according to the number of copper wires 400 to be connected on the distribution disc 100, thereby meeting the use of different products (different number of copper wires 400) and promoting the uniformity of the copper wire 400 winding arrangement on the insulating core. In addition, the wire passing module 200 of the present application is provided with a pressure sensor 220 and a wire passing module 230, the wire passing module 230 is connected with an elastic member 240, and the wire passing module 230 moves back and forth in the mounting chamber 211. When the copper wire 400 passes through the wire passing module 230, the tension of the copper wire 400 will give the wire passing module 230 a force towards the axis of the distribution disc 100, so that the wire passing module 230 moves in the direction of the axis of the distribution disc 100 in the mounting chamber 211. During the movement, the elastic member 240 will apply a corresponding force to the pressure sensor 220, so that the tension of each copper wire 400 can be indirectly monitored, the difference in the tension of the copper wire 400 can also be reflected, and the tension can be output to the PLC wireless control module 300 and the display screen, realizing the visualization of the tension of the copper wire 400, better serving the production, ensuring the uniformity of the tension of each copper wire 400, and improving the quality of the product.
[0048] In some comparative embodiments, the copper wire 400 breakage can only be checked by manual visual inspection, and the failure to find in time will cause a series of production problems. Therefore, in order to solve this problem, further, the application also includes an alarm component; the alarm component includes an electric signal sensor 500 electrically connected with the PLC wireless control module 300; along the X direction, the electric signal sensor 500 is arranged in the installation chamber 211 away from one end of the dividing disc 100, and the electric signal sensor 500 is located on one side of the wire passing module 230. Specifically, the electric signal sensor 500 is arranged in the embodiment, when the copper wire 400 breaks, the tension of the copper wire 400 will disappear, so that in the process of rotating the dividing disc 100, the wire passing module 230 will be thrown away from the axis of the dividing disc 100 under the action of centrifugal force, and the wire passing module 230 after being thrown away will collide with the electric signal sensor 500, so that the electric signal sensor 500 can identify and output the signal to the PLC wireless control module 300, that is, whether the copper wire 400 breaks can be identified.
[0049] Further, the alarm component further includes an audible and visual alarm component (not shown in the figure), and the audible and visual alarm component is electrically connected with the PLC wireless control module 300. Specifically, when the copper wire 400 breaks, the audible and visual alarm component can be used for warning, so that the operator can find in time. In some other embodiments, the PLC wireless control module 300 can be electrically connected with the power part of the stranding cage, and once the copper wire 400 breaks, the power part of the stranding cage can be controlled to stop for maintenance and other operations, thereby reducing product quality defects.
[0050] Further, the wire passing module 200 is detachably connected with the dividing disc 100. The outer side of the dividing disc 100 is provided with a flange 110; the wire passing module 200 further includes a U-shaped clamp 250 arranged at one end of the main body 210, one side of the U-shaped clamp 250 is provided with a threaded hole 251; the U-shaped clamp 250 is clamped on the flange 110, and a tightening screw (not shown in the figure) is threadedly connected in the threaded hole 251. Specifically, the connection mode of the embodiment facilitates the disassembly of the wire passing module 200, and can also ensure that the wire passing module 200 will not tilt or fail under stress.
[0051] Further, the X direction forms a predetermined angle α with the radial direction of the dividing disc 100, and the predetermined angle α is inclined from the rear side to the front side of the dividing disc 100 to the axis of the dividing disc 100. Specifically, the predetermined angle α is related to the distance between the dividing disc 100 and the sizing die 700 and the diameter of the dividing disc 100. Finally, the axis of the copper wire 400 is parallel to the axis of the wire passing module 230, thereby ensuring the accuracy of monitoring the tension value of the copper wire 400.
[0052] Further, the two sides of the installation chamber 211 are provided with a sliding groove 212 extending in the X direction, and the wire passing mold 230 reciprocates in the sliding groove 212. Specifically, the sliding groove 212 provides a guide for the reciprocating movement of the wire passing mold 230, avoiding the wire passing mold 230 from being skewed during movement, which may reduce the accuracy of the copper wire 400 tension value.
[0053] Further, the PLC wireless control module 300 is electrically connected with the wire passing module 200 through a wire.
[0054] Further, the wire distribution disc 100 is bolted to the front end of the stranding cage center tube 600, facilitating installation and disassembly.
[0055] Further, the elastic member 240 is a spring.
[0056] In actual use, first, the copper wire 400 needs to be threaded, and the process is as follows: the same number of wire passing molds 200 as the copper wire 400 is selected, and then the wire passing molds 200 are installed on the wire distribution disc 100. When installing the wire passing molds 200, the alarm assembly is in the off state (to avoid false alarms). In the initial state, the elastic member 240 is in a natural state. Then the wire tension of each stranding cage is manually adjusted before production until the display pressure value remains consistent. In this way, the stability and uniformity of the copper wire 400 tension can be ensured on one side.
[0057] The principle of the broken wire alarm is as follows:
[0058] After normal production, if the copper wire 400 is broken, the elastic member 240 will immediately return to the natural state due to the lack of tension after the copper wire 400 is broken, and at the same time, under the action of the rotating centrifugal force, the wire distribution mold will touch the top electrical signal sensor 500, and through wireless PLC processing and signal transmission, an alarm or automatic shutdown can be issued. This can greatly reduce the quality risk.
[0059] The principle of the copper wire 400 tension monitoring is as follows:
[0060] The reason for the copper wire 400 tension is that the copper wire 400 compresses the elastic member 240 to contact the pressure sensor 220, thereby reading the pressure value, which indirectly reflects the size of the wire tension value, thereby reflecting the difference in tension of each stranding cage.
[0061] The present application is mainly aimed at old equipment or stranding cages that do not use electromagnetic tension. The present application can indirectly realize the visualization of the copper wire 400 tension, has online alarm monitoring, and the number of threaded copper wires 400 can be adjusted. It not only promotes product production quality, but also greatly reduces the cost of equipment upgrading and replacement, is suitable for various stranding machine modifications, and has universality.
[0062] The application can be applied to other metal wires or other materials uniformly arranged in a spiral on the cable. The application indirectly realizes visualization of tension, has a copper wire breakage alarm function, and can realize adjustable number of threading holes, can ensure stability of tension of the copper wire, can meet uniformity of arrangement of the copper wire, and can also serve as a monitoring means to reduce labor.
[0063] Obviously, the above embodiments are only examples for clearly illustrating the application, and are not intended to limit the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. All the embodiments do not need to be exhausted here. The obvious changes or variations derived therefrom are still within the protection scope of the application.
