Description

Technical Field

[0001] This utility model relates to the field of cable core braiding technology, and specifically to a cable core braiding device. Background Technology

[0002] A braiding device is a machine that forms a braided structure by mechanically winding multiple fibers. The braiding device needs to braid a certain number of fibers, and the braided fiber structure will form the braided layer of the cable core.

[0003] Currently, during the braiding process, braiding devices typically use braiding fiber wheels to pull fibers from the spools of the braiding machine. Multiple braiding fiber wheels simultaneously weave to form a braided layer. After the braided layer is completed, it, along with the outer copper wire of the cable core, forms the cable's braided layer. The quality of the braided layer directly affects the overall cable quality. Breakage of the fibers during the braiding process directly impacts the quality of the braided layer, and consequently, the quality of the cable.

[0004] During the current fiber weaving process, the sensor comes into contact with the weaving fiber. The wear on the sensor itself is related to the detection signal of the broken fiber. When the sensor itself is worn, the detection signal of the sensor will deviate to a certain extent, which will affect the quality and efficiency of the weaving layer. Utility Model Content

[0005] This utility model provides a cable core braiding device to solve the problems of poor braiding quality and low braiding efficiency caused by broken wires in the prior art.

[0006] To address the aforementioned problems, this utility model provides a cable core braiding device, comprising: a lower frame, on which a cable body is wound on a feed reel; an upper frame is fixedly installed on the upper part of the lower frame; a braiding worktable is installed inside the upper frame; the braiding worktable is equipped with a rotating component, a support, and several braiding fiber placement devices; a wire bundling mold is provided on the support; braided cables are wound on a winding reel inside the upper frame; and braided cables are wound on a take-up reel inside the lower frame; the braiding worktable is also equipped with an oil baffle plate, on which at least three wire breakage sensing devices are fixedly installed.

[0007] The above solution involves installing an oil baffle on the braiding workbench and fixing at least three wire breakage sensors on the oil baffle to achieve automatic detection of wire breakage during the cable braiding process. When the cable breaks, the wire breakage sensor can issue an alarm signal in time, avoiding poor braiding quality due to wire breakage, thereby improving the braiding efficiency and quality of the cable core wire.

[0008] According to one embodiment of this utility model, the above-mentioned braided fiber placement device is provided with a mounting plate, a braided fiber wheel at the rear end of the mounting plate, a plurality of limiting rods and a plurality of guide rods, and a fiber sensor at the front end of the mounting plate. Through the above scheme, by setting a fiber sensor on the braiding workbench of the cable core braiding device, the fiber breakage during the braiding process can be detected. Once a breakage is detected, an alarm can be issued in time or measures can be taken to adjust it, thereby effectively preventing the problem of reduced braiding layer quality caused by breakage and improving the efficiency and product quality of cable core braiding.

[0009] According to one embodiment of the present invention, a guide wheel is installed at the front end of the aforementioned wire sensor. By setting the guide wheel, the wear caused by the longitudinal tension between the braided fibers and the wire sensor is reduced, thereby minimizing the signal deviation of the wire sensor and improving the braiding efficiency and quality of the cable core wire.

[0010] According to one embodiment of the present invention, the above-mentioned wire sensor and wire breakage detection device are both electrically connected to the cable core braiding device. With the above solution, when the wire sensor and wire breakage detection device alarm, the braiding device can be stopped immediately for inspection to control the quality of the braided layer.

[0011] According to one embodiment of the present invention, the above-mentioned thread breakage sensing device is provided with a sensing head, which is placed above the braided fiber. Through the above scheme, when the thread breaks during high-speed operation, the braided fiber is ejected by tension and hits the sensing head. The sensing head sends a signal to the thread breakage sensing device, thereby stopping the operation of the braiding device and further improving the accuracy of thread breakage sensing.

[0012] According to one embodiment of the present invention, at least three sets of the limiting rods are provided, each set consisting of two single rods. Through the above scheme, the path through which the braided fibers pass is restricted, thereby preventing the problem of signal deviation in the wire breakage sensing device.

[0013] According to one embodiment of the present invention, at least three guide rods are provided, and the braided fibers pass through the upper and lower parts of the guide rods in an S-shaped path, so that the cable core braiding device can more accurately control the arrangement of fibers and the braiding path, thereby effectively avoiding wire breakage and improving the braiding quality of the braided layer.

[0014] According to one embodiment of the present invention, a braided cable passes through the above-mentioned wire harness mold.

[0015] The technical advantages of this application are as follows:

[0016] This application provides a cable core braiding device that automatically detects wire breaks during the braiding process by incorporating multiple wire breakage sensors. Once a breakage is detected, an alarm signal is issued, and the braiding device is stopped immediately, preventing poor braiding quality due to wire breaks and thus improving the efficiency and quality of cable core braiding. Simultaneously, a fiber sensor is installed on each braiding fiber placement device to detect fiber breakage. Guide rollers reduce wear from longitudinal tension, minimizing signal deviation and further improving braiding efficiency and product quality. Attached Figure Description

[0022] The following will be combined with the appendix Figures 1-3 The embodiments of the technical solution of this application are described in detail below. The following embodiments are only used to illustrate the technical solution of this application more clearly, and are therefore only examples and should not be used to limit the scope of protection of this application.

[0023] Example 1

[0024] Reference Figure 1 and Figure 2This utility model provides a cable core braiding device, including: a lower frame 7, on which a cable body is wound on a feed reel 6 inside the lower frame 7; an upper frame 1 is fixedly installed on the upper part of the lower frame 7; a braiding worktable 3 is installed inside the upper frame 1; the braiding worktable 3 is provided with a rotating part 13, a support 8, and several braiding fiber placement devices 10; a wire bundling mold 9 is provided on the support 8; a braided cable 5 passes through the wire bundling mold 9; a winding reel 2 inside the upper frame 1 winds the braided cable 5; and a take-up reel 14 inside the lower frame 7 winds the braided cable 5; the braiding worktable 3 is also provided with an oil baffle 12; at least three wire breakage sensing devices 4 are fixedly installed on the oil baffle 12.

[0025] By installing an oil baffle 12 on the braiding workbench 3 and fixing at least three wire breakage sensing devices 4 on the oil baffle 12, automatic wire breakage detection during the braiding process of the cable body can be achieved. When the cable breaks, the wire breakage sensing device 4 can issue an alarm signal in time, avoiding the problem of poor braiding quality due to wire breakage, thereby improving the braiding efficiency and quality of the cable core wire.

[0026] Reference Figure 3 The braided fiber placement device 10 is equipped with a mounting plate 106. A braided fiber wheel 101 is located at the rear end of the mounting plate 106. The mounting plate 106 is provided with several limiting rods 102 and several guide rods 103. At least three sets of limiting rods 102 are provided, each set consisting of two single rods. At least three guide rods 103 are provided. The braided fiber 107 passes sequentially through the upper and lower parts of the guide rods 103 in an S-shaped path. A fiber sensor 105 is mounted at the front end of the mounting plate 106, and a guide wheel 104 is mounted at the front end of the fiber sensor 105. Through the above scheme… By installing a fiber sensor 105 on the braiding worktable 3 of the cable core braiding device, the fiber breakage during the braiding process can be detected. Once a breakage is detected, an alarm can be issued in time or measures can be taken to adjust it. By setting a guide wheel 104, the wear caused by the longitudinal tension between the braiding fiber 107 and the fiber sensor 105 is reduced, thereby minimizing the signal deviation of the fiber sensor 105 and effectively preventing the problem of the braiding layer quality deterioration caused by the breakage, thus improving the efficiency and product quality of cable core braiding.

[0027] Both the wire sensor 105 and the wire breakage detection device 4 are electrically connected to the cable core braiding device. The wire breakage detection device 4 is equipped with a sensing head 401, which is positioned above the braided fiber 107. Through this design, when the wire sensor 105 and the wire breakage detection device 4 alarm, the braiding device can be immediately stopped for inspection, controlling the quality of the braided layer. Specifically, the wire sensor 105 is a physical contact type, used to detect the braided fiber 107 near the mounting plate 106. By directly contacting the braided fiber 107, it monitors the tension or contact state of the braided fiber 107. When the braided fiber 107 breaks or its tension changes, the internal mechanical structure of the wire sensor 105 (such as a spring or lever) will displace. This displacement will trigger a switch or sensor, thereby generating an electrical signal transmitted to the braiding device, indicating a wire breakage or abnormal tension. The wire breakage sensing device 4 uses mechanical trigger detection. By installing the sensing head 401 above the braided fiber 107, it is used to detect the braided fiber 107 near one end of the braided cable 5. When the braided fiber 107 breaks during the braiding process, the end of the broken braided fiber 107 will fall or swing up and down due to gravity or inertia until it touches the pre-arranged sensing head 401, which controls the opening or closing of the internal micro switch, changes the circuit state, and generates an electrical signal that is transmitted to the braiding device to indicate wire breakage or abnormal tension.

[0028] Working principle:

[0029] The cable body is released from the feed roller 6 in the lower frame 7. The cable body is braided into a layer by the braiding fiber placement device 10 of the braiding workbench 3. The braided cable 5 is wound onto the winding roller 2 through the wire bundling mold 9 and wound onto the take-up roller 14 through the through hole 11. During the braiding process, if the braiding fiber 107 breaks, the wire breakage sensing device 4 or the wire sensor 106 will sense it and output a signal to the cable core wire braiding device to stop the machine for inspection.
