[0003] like figure 1 As shown, the existing spindle device comprises a freely rotatable spindle shaft 21, a control arm 22, a brake pad 23 and a cylinder 24. The spindle shaft 21 is wound with a steel wire coil, and the steel wire passes through the control arm 22 after unwinding. The guide roller is led out, and in this process, it drives the control arm to move toward the spindle shaft 21, drives the brake pad 23 to loosen, the spindle shaft 21 rotates and drives the steel wire to unwind, and at the same time, the cylinder rod 241 of the cylinder 24 overcomes the resistance and elongates, and the cylinder rod 241 elongates and drives the brake pad 23 to move toward the spindle shaft 21 to generate frictional resistance, so that the spindle shaft 21 stops rotating, and the steel wire drawn out like this has a certain tension, but because the spindle shaft rotates passively under tension, in most cases, the spindle The device is synchronously rotated by multiple groups, so the steel wires drawn out by different groups of spindle devices may have differences, which makes the uniformity of the rolling tension of the steel wires poor, resulting in inconsistent thickness of the steel wires, warping, angles, and discounts, which directly affect the rubber. The quality of the cutting process

Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0023] See Figure 2 to Figure 5 As shown, the present invention discloses a spindle rack 100 for storing and rotationally releasing coils of wire material. In this embodiment, the linear material coil is a steel wire coil. The spindle rack 100 includes a lifting mechanism 1 , a body 2 arranged at the driving end of the lifting mechanism 1 , and a spindle structure 3 installed on the same side of the body 2 . The lifting mechanism 1 is preferably an air cylinder,...

The invention provides a spindle structure, which includes a rotating roller capable of rotating with a center shaft, a support base arranged at one end of the center shaft and used for supporting thecenter shaft, and a first support rod arranged on the support base, as well as a driving mechanism for driving the center shaft to rotate, and a tensioner arranged on the first support rod, wherein the tensioner is provided with a rotating shaft with adjustable damping, and a thread object guided out from the rotating shaft has stable tension through the driving mechanism for controlling the rotating speed of the center shaft and / or the tensioner for controlling the rotating speed of the rotating shaft. The invention further provides a spindle rack with the spindle structure, so that tensionof the spindle structure can be accurately controlled, and the structure is simple, and the cost is lower.
Description
technical field [0001] The invention relates to the field of tire production equipment, in particular to a spindle structure and a spindle frame with the spindle structure. Background technique [0002] The steel wire strip calendering process is one of the important processes in the manufacture of steel wire strips. The qualified steel cord coil passes through the spindle device, and is guided to the warping roller and pressure roller of the corresponding density under the control of its tension, and then with the Corresponding mixer rubber forms steel wire strips with a certain density under the rolling of the calender. [0003] Such as figure 1 As shown, the existing spindle device comprises a freely rotatable spindle shaft 21, a control arm 22, a brake pad 23 and a cylinder 24. The spindle shaft 21 is wound with a steel wire coil, and the steel wire passes through the control arm 22 after unwinding. The guide roller is led out, and in this process, it drives the contro...
