[0018] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed description is given in conjunction with the embodiments.
[0019] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0020] Please refer to Figure 1 and Figure 2 A wire breaking protection device 100 for a stranding machine includes a rear deformer 1 capable of outputting a steel wire rope 101 along a first direction X, a fixing plate 2, an adjusting bolt 3, an adjusting nut 4, a first insulating washer 5, a second insulating washer 6, a shutdown copper block 7 and a shutdown conductor 8.
[0021] The fixing plate 2 is fixed on one side of the output wire rope 101 of the rear deformer 1. The rear deformer 1 is the last position on the stranding machine that is prone to wire breakage and wire shortage. The wire breakage protection device 100 is arranged here to better ensure the final wire rope product quality.
[0022] The adjusting bolt 3 passes through the fixing plate 2 , the first insulating washer 5 , the shutdown copper block 7 and the second insulating washer 6 along the first direction X and is then locked in the adjusting nut 4 , so as to fix the shutdown copper block 7 on the fixing plate 2 in an insulated manner.
[0023] A wire through hole 71 and a bolt hole 72 are provided on the shutdown copper block 7 along the first direction X, and a lateral wire entry groove 73 is provided on the side wall of the wire through hole 71 to facilitate the wire rope 101 to pass into the wire through hole 71 from the side of the shutdown copper block 7, and the adjusting bolt 3 passes through the bolt hole 72 without contact.
[0024] One end of the shutdown wire 8 is connected to the shutdown copper block 7, and the other end is connected to the power-off switch of the stranding machine.
[0025] Among them, the steel wire rope 101 passes through the wire through hole 71 of the shutdown copper block 7 without contact. When the wire breaks, as long as it touches the shutdown copper block 7, the stranding machine will immediately stop under the action of the power-off switch, thereby reducing the probability of the steel wire rope 101 being short of wire, reducing defective products, and thus reducing losses.
[0026] Optionally, the bolt hole 72 is a waist-shaped hole, and the adjusting bolt 3 can move up and down through the bolt hole 72 along the waist edge of the bolt hole 72. This arrangement is convenient for adjusting the height position of the wire through hole on the shutdown copper block to adapt to steel wire ropes of different output heights.
[0027] Optionally, the broken wire protection device 100 further comprises an insulating sleeve 9, which is sleeved on the adjusting bolt 3 and located in the bolt hole 72. This facilitates the insulation of the bolt and the shutdown copper block.
[0028] Preferably, the length of the insulating sleeve 9 along the first direction X is equal to the thickness of the shutdown copper block 7 along the first direction X. Such arrangement of the adjusting bolt and the shutdown copper block has a better insulation effect and does not affect the fastening installation of the shutdown copper block.
[0029] Optionally, the wire-passing through hole 71 is a circular hole, and the inner diameter of the wire-passing through hole 71 is larger than the diameter of the steel wire rope 101. This facilitates the wire rope to pass through and facilitates better detection of broken wires.
[0030] Optionally, the bolt hole 72 is located at the lower side of the wire through hole 71. This arrangement facilitates the wire rope to pass through the wire through hole without interference.
[0031] Optionally, the first insulating gasket 5 and the second insulating gasket 6 have the same model and specification. This arrangement is convenient for purchase and maintenance.
[0032] Optionally, the lateral wire inlet groove 73 is vertically connected to the side wall of the wire through hole 71 along the second direction Y, and the first direction X is perpendicular to the second direction Y. This arrangement is more convenient for wire rope threading.
[0033] Optionally, the shutdown wire 8 is connected to the bottom of the shutdown copper block 7. This arrangement facilitates the laying of the shutdown wire and reduces bending.
[0034] The broken wire protection device for the stranding machine of the utility model has a simple structure, is easy to operate and the broken wire protection is timely and reliable. As long as broken wires on the wire rope touch the shutdown copper plate, the stranding machine will stop immediately, which greatly reduces the problem of insufficient wires in the wire rope caused by the failure of the broken wire protection. It not only improves product quality but also improves work efficiency and reduces losses.
[0035] The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any changes and modifications made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
