Description

Technical Field

[0001] The utility model relates to the technical field of steel cord production, in particular to a broken wire detection device for twisting steel wires. Background Art

[0002] During the production process of steel wire products, wire breakage is inevitable. In order to ensure that wire breakage can be discovered in time and production can be stopped, various types of wire breakage alarm devices are needed. Usually, the wire breakage alarm device detects the surface of the entire rope after the wire is twisted into a rope to confirm whether there is wire breakage. Different wire pay-off devices will also have different detection devices. For example, an alarm is realized by detecting whether the pay-off wheel stops rotating (when the wire is broken, there is no wire on the surface of the pay-off wheel, and it will no longer rotate).

[0003] However, in the actual production process, the wire breaking points are different, especially between pay-off and rope formation. The wires often break when twisting into ropes, especially in the twisting process of multi-layer structures. The outermost layer has no broken wires normally, but the inner layer of steel wire is broken. If the detection device does not detect any broken wires on the surface, it may cause serious quality risks. Utility Model Content

[0024] In order to better understand the technical content of the present invention, specific embodiments are given and described below with reference to the accompanying drawings.

[0025] Combine Figure 1 As shown, the first aspect of the utility model proposes a broken wire detection device for twisted steel wire, including a support plate 1, a copper ring structure 2 and an alarm circuit 3. A wire passing component 14, a wire branching component and a wire collection nozzle 13 are provided above the support plate 1. The copper ring structure 2 is arranged on the side of the wire branching component close to the wire passing component 14. The steel wire passes through the copper ring structure 2, the wire branching component and the wire collection nozzle 13 in sequence through the wire passing component 14.

[0026] It should be understood that when the steel wire is twisted, it is twisted according to a certain structure, such as a double or triple layer structure. The wire splitting component is intended to distribute multiple steel wires in predetermined positions, such as Figure 2 As shown, the wire dividing component includes a plurality of wire holes 121 distributed according to predetermined positions, which are used to divide the steel wires into several annular areas, and then pass through the wire collection nozzle 13 together to be twisted.

[0027] Optionally, the branching component includes a support frame 11 and a branching plate 12, wherein the branching plate 12 is provided with a plurality of branching holes 121, and the branching plate 12 is detachably connected to the support frame 11. In this way, different branching plates 12 can be replaced according to production specifications to form steel cords of different specifications.

[0028] like Figure 2 As shown, the dividing plate 12 includes three layers of dividing holes, namely the inner layer, the middle layer and the outer layer, which are used to produce steel cords with specifications of 3*8*15. It can be understood that the three steel wires in the inner layer are in the first annular area, the eight steel wires in the middle layer are in the second annular area, and the 15 steel wires in the outer layer are in the third annular area.

[0029] Furthermore, the positive lead 31 of the alarm circuit 3 is connected to the copper ring structure 2, and the negative lead 32 of the alarm circuit 3 is connected to the wire-passing component 14. The copper ring structure 2 is configured to include multiple layers of copper rings, and the copper rings are located at the boundary of the annular areas (for example, the boundary of the first annular area 12a, the second annular area 12b or the third annular area 12c). The alarm circuit 3 is configured to contact the copper ring when the steel wire in different annular areas breaks, so that the alarm circuit 3 is closed and an alarm signal is emitted.

[0030] Optionally, the alarm circuit 3 can provide an audible and visual alarm after being closed.

[0031] In this way, when any layer of steel wires in the middle layer breaks, it will come into contact with the nearby copper rings, causing the alarm circuit 3 to close and send out an alarm signal.

[0032] For a double-layer structure, the distance between layers is large, and after the inner layer steel wire breaks, it is not easy to be caught by the outer layer steel wire. A copper ring can be set on the outer layer of the double-layer structure, or a copper ring can be set outside each of the two layers of steel wire. Figure 3 As shown, the first copper ring 23 is arranged outside the three layers of steel wires in the inner layer, and the second copper ring 22 is arranged outside the nine steel wires in the outer layer.

[0033] However, for the three-layer steel wire structure, the spacing between the inner, middle and outer steel wires is small. When the inner or middle steel wire breaks, it is easily transported forward by the outer steel wire and will not fall off. Therefore, at least two copper rings are required.

[0034] like Figure 4 As shown in the figure, if the distance between the middle and outer steel wires is close, the inner steel wire will be easily caught by the middle or outer steel wire when it breaks. Therefore, a copper ring is set between the inner and middle layers, and another copper ring is set on the outermost layer. In this way, when the inner, middle or outer steel wire breaks, it will contact the copper ring in time to generate an alarm, and the detection of broken wires will be more sensitive.

[0035] like Figure 5 As shown, if the distances between the inner layer, the middle layer and the outer layer are roughly the same, in order to increase the detection sensitivity, a copper ring can be set outside the inner layer, the middle layer and the outer layer respectively. In this way, when the steel wire of the inner layer, the middle layer or the outer layer is broken, it will contact the copper ring in time to activate the alarm, and the detection of broken wires will be more sensitive.

[0036] In the above embodiment, the length and diameter of the copper ring correspond to the product specifications. Preferably, after arrangement, the distance between the copper ring and the steel wire is less than or equal to 5 mm to ensure detection sensitivity.

[0037] In an optional embodiment, the surface of the support plate 1 is provided with a strip groove, the length direction of the strip groove being the direction in which the steel wire passes through. The copper ring structure 2 is connected to the strip groove and can change the spacing between it and the branching component. It should be understood that due to the branching function of the branching plate 12, the closer the position is to the branching plate 12, the more obvious the stratification of the multiple steel wires. The obvious stratification is more conducive to the effectiveness of the copper ring to achieve alarm. Preferably, the spacing between the copper ring structure 2 and the branching component is 10-20 cm.

[0038] In an optional embodiment, the copper ring structure 2 includes a copper rod 21 and multiple copper rings, the first end of the copper ring is connected to the copper rod 21, the second end of the copper ring is a free end 24, and a closable gap 25 is formed between the free end 24 of the copper ring and the copper rod 21.

[0039] Thus, when arranging the copper ring, the free end 24 is broken open, and the steel wire is filled into the corresponding position, and the free end 24 is closed to make the gap 25 as small as possible to prevent the steel wire from falling from the gap 25 after breaking.

[0040] Optionally, an insulating gasket 15 is provided between the copper ring structure 2 and the support plate 1. Specifically, the bottom of the copper rod 21 is provided with a thread, and the copper ring structure 2 is fixed to the support plate 1 by providing a nut and an insulating gasket at the bottom of the copper rod 21.

[0041] In an optional embodiment, the line passing component 14 includes a line passing roller or a line passing wheel.

[0042] In combination with the above embodiments, the present device sets a contact alarm device composed of multiple layers of open copper rings in front of the distribution disk, and uses multiple copper rings of different sizes to specifically detect whether the steel wires of each layer of the double-layer or triple-layer structure cord are broken, ensuring that the inner and outer layers of steel wire can be broken and the machine can be stopped in time to ensure the sensitivity of the detection.

[0043] While the present invention has been described above with reference to preferred embodiments, this is not intended to limit the present invention. Persons skilled in the art will readily appreciate that various modifications and variations may be made without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
