Description

Technical Field

[0001] This utility model relates to the field of steel wire processing technology, and in particular to a steel wire traction device. Background Technology

[0002] Steel wire is a reprocessed product made from hot-rolled coils through cold drawing. It is one of the four major types of steel and comes in various shapes, including round, square, oval, and triangular. The main manufacturing method involves cold drawing from hot-rolled coils. Due to its excellent physical and chemical properties, this material is widely used in various fields, such as construction, automobile manufacturing, and wire and cable production. With technological advancements, steel wire production is moving towards higher quality materials, larger coils, higher speeds, continuous production, and energy conservation.

[0003] When stainless steel wire is being wound up, a traction device is needed. However, if a malfunction occurs during the winding process and the equipment needs to be stopped urgently, the wire wound on the traction device is prone to unraveling. After the malfunction is resolved, the unraveled wire needs to be rewound onto the traction wheel, which is time-consuming, laborious, and affects the winding efficiency.

[0004] Therefore, it is necessary to develop a wire traction device to improve the wire winding efficiency. Utility Model Content

[0021] The first gear meshes with two of the second gears.

[0022] Preferably, a plurality of annular grooves are provided at equal intervals on the curved surface of the pair of traction wheels;

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] like Figure 1 and Figure 4 As shown, a wire traction device of this utility model includes a support frame 1, a pair of traction wheels 2, a drive mechanism, and a wire pressing mechanism.

[0041] One end of the support frame 1 is the feeding end, and the other end is the discharging end.

[0042] The pair of traction wheels 2 are located on the same side of the support frame 1, and the centers of the pair of traction wheels 2 are at the same height.

[0043] The drive mechanism is used to drive the pair of traction wheels 2 to rotate.

[0044] In this embodiment, as Figure 4As shown, the driving mechanism includes a motor 3, a reduction gearbox 4, and a rotating shaft 5; both the motor 3 and the reduction gearbox 4 are mounted on the support frame 1; the output end of the motor 3 is connected to the input end of the reduction gearbox 4; the output end of the reduction gearbox 4 is connected to the rotating shaft 5; the rotating shaft 5 is horizontally rotatably mounted on the support frame 1; a first gear 6 is fixed to the outer end of the rotating shaft 5, and a second gear 7 is fixed to the rear side of each pair of traction wheels 2, the second gear 7 sharing the same axis with the traction wheel 2; the first gear 6 meshes with the two second gears 7; thus, under the drive of the motor 3 and the control of the reduction gearbox 4, the first gear 6 on the rotating shaft 5 rotates, thereby causing the two second gears 7 to rotate, ultimately driving the pair of traction wheels 2 to rotate, thus achieving the traction of the steel wire.

[0045] like Figure 1 and Figure 2 As shown, the pressing mechanism includes a base 8, a cylinder 9, a connecting rod 10, and a nylon pressing roller 11; the base 8 is located near the feed end of the support frame 1; the bottom of the cylinder 9 is hinged to the base 8, and the piston rod of the cylinder 9 is hinged to the upper part of the connecting rod 10; the bottom of the connecting rod 10 is hinged to the base 8; the nylon pressing roller 11 is rotatably mounted on the top of the connecting rod 10 and faces the curved surface of the traction wheel near the feed end of the support frame 1.

[0046] When the steel wire is being pulled, it enters from the feed end of the support frame 1 and then winds around a pair of traction wheels 2 in sequence. Under the traction of the traction wheels 2, it is conveyed. When the steel wire malfunctions during the winding process, the cylinder 9 is activated, the piston rod extends, and the connecting rod 10 rotates, so that the nylon pressure roller 11 presses on the traction wheel near the feed end, pressing down on the steel wire and preventing it from unraveling.

[0047] In this embodiment, as Figure 2 As shown, a plurality of annular grooves 12 are provided at equal intervals on the curved surface of the pair of traction wheels 2; at least two annular protrusions 13 are provided at equal intervals on the curved surface of the nylon pressure wheel 11, and the spacing between the annular protrusions 13 is adapted to the spacing between the annular grooves 12; this arrangement allows the nylon pressure wheel 11 to press down on the traction wheels more effectively.

[0048] Furthermore, the nylon pressure roller 11 has two annular protrusions 13, which are directly opposite the two annular grooves 12 at the outermost end of the traction roller, pressing down the steel wire at the outermost end of the traction roller and effectively improving the pressing effect.

[0049] In this embodiment, as Figure 3As shown, the steel wire traction device further includes a meter-counting mechanism; the meter-counting mechanism includes a mounting base 14, a meter counter 15, and a third gear 16; a fourth gear 17 is fixed to the front end of the traction wheel near the discharge end of the support frame 1, and the fourth gear 17 shares the same axis with the connected traction wheel; the meter counter 15 is mounted on the mounting base 14; the third gear 16 is mounted at the input end of the meter counter 15 and meshes with the fourth gear 17; with this configuration, the rotation of the fourth gear 17 drives the rotation of the third gear 16, enabling the meter counter 15 to calculate the length of the traction steel wire and achieve fixed-length wire take-up.

[0050] In this embodiment, as Figure 5 As shown, a protective cover 18 is hinged to the top of the support frame 1. The protective cover covers and closes a pair of traction wheels, which serves to protect them and prevent external foreign objects from colliding with the traction wheels and affecting the traction operation of the steel wire.

[0051] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
