Description

Technical Field

[0001] This utility model relates to a wire feeding device, specifically a device for effectively adjusting the winding speed of the outer wire of steel cord. Background Technology

[0002] Steel cord is a structure composed of two or more steel wires, or a combination of strands or wires. It is primarily used as a carcass material in tires, especially radial tires. Steel cord is made of high-quality high-carbon steel and plated with brass, possessing characteristics such as high strength and corrosion resistance.

[0003] Currently, during the manufacturing process of steel cord, the outer wire needs to be spirally wound onto the center wire. However, the winding speed of the outer wire during unwinding cannot be effectively and quickly adjusted, resulting in the outer wire sometimes being too densely wound onto the center wire and sometimes too sparsely wound, leading to substandard winding quality.

[0004] Therefore, it is desirable to provide a device for effectively adjusting the winding speed of the outer wire of steel cord, so as to effectively solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a device for effectively adjusting the winding speed of the outer wire of steel cord, thereby controlling the winding speed of the outer wire and making the outer wire evenly wound on the center wire.

[0006] To achieve the above-mentioned utility model objectives, this utility model provides a device for effectively adjusting the winding speed of the outer wire of steel cord, including a support shaft, a mounting sleeve, and an adjusting component;

[0007] The support shaft is horizontally fixed on the external wire feeding bracket;

[0008] The mounting sleeve is fitted and fixed on the support shaft to fix the I-beam reel to be laid out;

[0009] The adjusting component includes a first sleeve portion, a support rod, and a second sleeve portion;

[0010] The support shaft is provided with a bearing on the outside of the mounting sleeve, and the first sleeve is rotatably mounted on the support shaft through the bearing;

[0011] The support rod is fixed to the outer wall of the first sleeve along the radial direction of the first sleeve, and the outer end of the support rod is provided with a guide sleeve for the outer thread to pass through;

[0012] The second sleeve is threaded onto the support shaft and is located outside the first sleeve;

[0013] The second socket and the side facing each other are provided with a friction layer.

[0014] Preferably, the guide sleeve is engaged with the outer end of the support rod.

[0015] Preferably, the outer end of the support shaft has a threaded hole, and a bolt is threaded into the threaded hole.

[0016] This utility model discloses a device for effectively adjusting the winding speed of the outer wire of steel cord. By threading a second sleeve onto a support shaft and adjusting the friction between the first sleeve and the second sleeve, the rotation speed of the first sleeve is effectively controlled, thereby allowing the outer wire to be evenly wound on the center wire and accelerating the production efficiency of steel cord.

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0020] Example

[0021] like Figure 1 As shown, this embodiment of a device for effectively adjusting the winding speed of the outer wire of steel cord includes a support shaft 1, a mounting sleeve 2, and an adjusting component.

[0022] The support shaft 1 is horizontally fixed on the external wire feeding bracket;

[0023] The mounting sleeve 2 is sleeved and fixed on the support shaft 1 to fix the I-beam spool 3 to be laid; the adjusting component includes a first sleeve 4, a support rod 5 and a second sleeve 6; the support shaft 1 is provided with a bearing 7 on the outside of the mounting sleeve, and the first sleeve 4 is rotatably mounted on the support shaft 1 through the bearing 7; the support rod 5 is fixed radially to the outer wall of the first sleeve 4, and the outer end of the support rod 5 is provided with a guide sleeve 8 for the outer thread to pass through.

[0024] In this embodiment, the guide sleeve 8 is snapped onto the outer end of the support rod 5 to achieve a detachable connection, which facilitates disassembly.

[0025] like Figure 2As shown, the second sleeve 6 is threaded onto the support shaft 1 and is located outside the first sleeve 4; the second sleeve 6 and the first sleeve 4 are both provided with friction layers on their facing sides.

[0026] When it is necessary to adjust the winding speed of the outer yarn, the position of the second socket 4 on the support shaft 1 is rotated so that the friction layers on the first socket 4 and the second socket 6 come into contact, thereby effectively adjusting the rotation speed of the first socket 4.

[0027] Here, the inventor needs to explain that the first socket 4 is a driven wire release part and has no driving device to drive it to rotate. The external wire take-up device pulls the first socket part to rotate.

[0028] In this embodiment, the outer end of the support shaft 1 has a threaded hole, and a bolt 9 is threaded into the threaded hole. This arrangement limits the second sleeve 6 and prevents it from falling off the support shaft 1.

[0029] The preferred embodiments of this utility model have been described in detail above, but this utility model is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
