After the rolled material passes through, it is reeled up by the wire take-up machine. During the whole process, the center distance between the first rolling roller shaft 12 and the second roller shaft 13 remains unchanged. When it is necessary to adjust the center distance between the first roller ring 2 and the second roller ring 3, the telescopic part 7 is extended and retracted, the power part remains stationary, and the second rocker arm 5 drives the outer peripheral surface of the second eccentric sleeve to rotate, and the first sector tooth end 18 of the first eccentric sleeve engages and rotates with the second sector tooth end 19 of the second eccentric sleeve, driving the outer peripheral surface of the first eccentric sleeve to rotate, realizing the rotation of the first eccentric sleeve and the second eccentric sleeve, thereby driving the center distance of the first rolling roller shaft 12 and the second rolling roller shaft 13 to change, and then adjusting the size of the roller ring channel 201 formed between the first roller ring 2 and the second roller ring 3 to provide resistance or thrust to the rolled material passing through the roller ring channel 201.

[0049] The front clamping roller device of the wire take-up machine provided by the present invention has the following advantages: (1) the front clamping roller device of the wire take-up machine is arranged in front of the wire take-up machine, so that the force on the rolled material conveyed to the wire take-up machine is more uniform; (2) by arranging the first eccentric sleeve and the second eccentric sleeve, the size of the roller ring channel 201 formed between the first roller ring 2 and the second roller ring 3 can be adjusted; (3) when the distance between the first roller ring 2 and the second roller ring 3 increases, the roller rings can be quickly replaced; (4) due to the telescopic member 7, the roller ring channel 201 formed between the first roller ring 2 and the second roller ring 3 can be maintained, so that the clamping force and time of the roller ring channel 201 can be controlled; (5) the center distance between the first roller ring 2 and the second roller ring 3 of the clamping roller device can be adjusted in a box, which reduces the occupied area during use, makes the overall structure simpler, and has a compact layout.

[0050] As an alternative embodiment, the telescopic member 7 may also be other components such as a telescopic air cylinder, a telescopic hydraulic cylinder, etc.

[0051] As an alternative embodiment, the limit rod 6 can also be replaced by a telescopic member 7, that is, the telescopic end of the telescopic member 7 is connected to the first connecting end 402 of the first rocker arm 4 to achieve synchronous adjustment of the two telescopic members 7.

[0052] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description.
