Description

Technical Field

[0001] The utility model relates to the technical field of steel cord production, in particular to a device for online detection of steel cord groove dropout. Background Art

[0002] The steel cord production process begins with the pay-off of a single filament, which is then formed into a rope at the wire-collecting nozzle pressure shoe. The rope then passes through a twister to relieve stress, a straightener to adjust the arc height and straightness, and finally a torsion control feedback device before winding up. During this process, the cord passes through dozens of pulleys of various sizes, and any of these pulleys carries the risk of falling, making it crucial to perform a thorough inspection before starting the machine.

[0003] During long-term production, the inventors discovered that the cord pulley below the torsion control (ATC) device frequently lost its groove. Often, the cord was discovered to be lost only after the reel had fully stopped. Such reels would need to be rewound and rewound to confirm the problem. Furthermore, when the cord was not within the positioning guide groove, the torsion sensed by the ATC device was not the actual cord torsion. Based on the erroneous torsion sensing signal, the ATC would make incorrect adjustments, which could easily cause the cord torsion to exceed customer standards, resulting in scrap and increased market costs.

[0004] Therefore, it is very necessary to be able to promptly and effectively detect when the wire wheel under the ATC device falls out of the groove. Utility Model Content

[0020] The accompanying drawings are not intended to be drawn to scale. In the accompanying drawings, each identical or nearly identical component shown in various figures may be represented by the same reference numeral. For the sake of clarity, not every component is labeled in every figure. Embodiments of various aspects of the present invention will now be described by way of example and with reference to the accompanying drawings, in which:

[0021] Figure 1 This is a structural diagram of a device for online detection of steel cord groove failure shown in the present invention;

[0022] Figure 2 It is a wiring diagram of the signal trigger circuit shown in the present invention. DETAILED DESCRIPTION

[0023] 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.

[0024] Combine Figure 1 As shown, the first aspect of the utility model proposes an online device for detecting steel cord groove falling, including a wire roller support plate 10, a metal plate 20, a pair of wire rollers and a signal trigger circuit 40, the metal plate 20 is connected to the top of the wire roller support plate 10, and a wire groove 201 is provided on the metal plate 20; a pair of wire rollers are connected to the wire roller support plate 10, and the pair of wire rollers include a first wire roller 31 and a second wire roller 32 connected to the wire roller support plate 10, and the cord passes around the first wire roller 31, the torsion control feedback device 30 above the metal plate 20 and the second wire roller 32 in sequence.

[0025] In this way, after the steel cord passes around the first wire wheel 31, it passes through the wire groove 201 on the metal plate 20, and then passes around the torsion control feedback device 30, passes through the wire groove 201 on the metal plate 20, and then passes around the second wire wheel 32 to exit the line. Since it is easy for the line to fall out of the groove at the positions of the first wire wheel 31 and the second wire wheel 32, when the connecting line falls out of the groove on the first wire wheel 31 and the second wire wheel 32, the torsion sensed by the ATC device is not the objective torsion of the cord. Therefore, it is necessary to detect in time when the cord falls out of the groove.

[0026] Furthermore, the signal trigger circuit 40 is provided with a first lead 42 and a second lead 43 , and the signal trigger circuit is configured to trigger an action signal when the first lead 42 and the second lead 43 come into contact with each other.

[0027] Among them, the wire passing wheel support plate 10 and the metal plate 20 are insulated from each other, the first lead 42 is connected to the metal plate 20, the second lead 43 is electrically connected to the first wire passing wheel 31 and the second wire passing wheel 32, and the width of the wire passing groove 201 is smaller than the width of the first wire passing wheel 31 and the second wire passing wheel 32.

[0028] In this way, when the steel cord falls out of the groove at the first passing wheel 31 or the second passing wheel 32, it will inevitably move to the side of the first passing wheel 31 or the second passing wheel 32. At this time, the steel cord will contact the side wall of the passing groove 201, and through the conductive effect of the metal plate 20, the first lead 42 and the second lead 43 of the signal trigger circuit 40 will be electrically connected to each other, closing the circuit and triggering the action signal.

[0029] In an optional embodiment, the signal trigger circuit is connected to the alarm and / or the machine driving component to generate an alarm and / or stop the machine.

[0030] In this way, the machine can be stopped quickly and an alarm can be sounded, and workers can deal with the fallen groove to avoid quality risks caused by continuous winding.

[0031] When the first lead 42 and the second lead 43 of the signal trigger circuit 40 form a closed circuit with each other, and the first lead 42 is connected to the metal plate 20, the second lead 43 needs to be connected to the surface of the metal part in contact with the steel cord, such as the first wire wheel 31, the second wire wheel 32 and the wire wheel support plate 10.

[0032] Furthermore, it is necessary to ensure that the wire roller support plate 10 and the metal plate 20 are insulated from each other. Furthermore, a first insulating pad 21 is provided between the metal plate 20 and the wire roller support plate 10. Preferably, the first insulating pad 21 comprises a rubber pad. In this way, the metal plate 20 and the wire roller support plate 10 are insulated from each other.

[0033] Combine Figure 1-2 As shown, in a specific embodiment, a first lead wire 42 is provided with a wiring clamp 41 at one end thereof, and the wiring clamp 41 is fixed to the surface of the metal plate 20 by a pressing screw 22 .

[0034] Among them, the clamping screw 22 not only plays the role of fixing the wiring clamp 41, but also plays the role of fixing the wire wheel support plate 10 and the metal plate 20 together. Therefore, a second insulating pad 23 is provided between the clamping screw 22 and the wiring clamp 41 to insulate the clamping screw 22 and the wiring clamp 41 from each other. At the same time, the hole on the wire wheel support plate 10 is larger than the diameter of the clamping screw 22, so that the clamping screw 22 does not contact the wire wheel support plate 10 when passing through the hole. Therefore, the clamping screw 22 is insulated from the wire wheel support plate 10 as a whole.

[0035] In an optional embodiment, the second lead 43 includes two wires, a first wire connected to the rotating shaft of the first wire-passing wheel 31, and a second wire connected to the rotating shaft of the second wire-passing wheel 32. In this way, when the steel cord on the first wire-passing wheel 31 or the second wire-passing wheel 32 falls out of the groove, the steel cord will contact the wire-passing wheel support plate 10, and the steel cord will also be electrically connected to the second lead 43, so that the first lead 42 and the second lead 43 close the trigger circuit with each other.

[0036] In other embodiments, the rotating shafts of the first and second wire passing wheels 31, 32 are metal rotating shafts, which are connected to the wire passing wheel support plate 10, and the second lead wire 43 is connected to the wire passing wheel support plate 10. In this way, the conductive path of the second lead wire 43 is the second lead wire 43 - wire passing wheel support plate 10 - the first and second wire passing wheels 31, 32 - the steel cord.

[0037] In combination with the above embodiments, the utility model arranges a metal plate with a wire passing groove above the first wire passing wheel and the second wire passing wheel where the groove is likely to fall out, and connects the metal plate and the steel cord to the positive and negative poles of the signal trigger circuit respectively. Once the steel cord falls out of the groove, the steel cord will contact the side wall of the metal plate wire passing groove, closing the signal trigger circuit. The staff can deal with the groove falling in time, avoiding the subsequent rewinding caused by the failure to detect the groove falling in time and possible quality risks.

[0038] 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.
