Specifically, the guide rollers 4 are arranged side by side in parallel, and a gap may be formed between two adjacent guide rollers 4, or the adjacent guide rollers may be in close contact with each other. Each guide roller 4 is rotatable relative to the support device 1 to roll the wire past the guide rollers 4. The number of the guide rollers 4 can be determined according to practical situations, and the embodiment does not limit the number.

Specifically, the first limiting mechanism 2 and each guide roller 4 have a preset vertical distance therebetween, and the preset vertical distance is used for limiting the wire between the first limiting mechanism 2 and each guide roller 4 and preventing the wire from being separated from the first limiting mechanism 2. In specific implementation, the preset vertical distance may be determined according to actual situations, and this embodiment does not limit this. Preferably, the first limiting mechanism 2 is located at the middle position of each guide roller 4 to better limit the wire jumping.
The second limiting mechanism 3 is connected to the supporting device 1, and the second limiting mechanism 3 is used for limiting the transverse movement (the vertical direction shown in fig. 6) of the wire, that is, the second limiting mechanism 3 is used for limiting the left-right shaking of the wire, so that the wire is conveyed into the paying-off reel of the tension machine along each guide roller 4.
When the wire guiding device is used, wires on the wire guiding disc pass through the guiding rollers 4 and are conveyed into the wire releasing winding drum along the guiding rollers 4. In the process of conveying, the inevitable wire can jump up and down, and in order to prevent the wire from being separated from the guide device, the first limiting mechanism 2 limits the upward jump of the wire, so that the wire is driven along each guide roller 4. In the use, the position of placing of tensioner and wire dish probably is not standard, just so makes the wire rock about easily, and then second stop gear 3 restricts the lateral shifting of wire, ensures that the wire rolls 4 conveying along each direction.
It can be seen that in the embodiment, by arranging at least two guide rollers 4 arranged in parallel, the bending radian of the guide device can be effectively increased, so that the lead can be smoothly conveyed along each guide roller 4, the lead is prevented from bearing large bending stress, the lead can be stably conveyed to a paying-off reel from each guide roller 4 without bending to a large extent, even if the lead is a carbon fiber lead, the lead can be stably conveyed, the damage of the lead is avoided, the lead is effectively protected, the normal use of the lead is ensured, the problem that the lead is easily damaged due to the fact that the diameter of a main support guide roller in the lead guide device for paying-off of a tensioner in the prior art is small, and the lead is subjected to large bending stress is solved, and moreover, the guide rollers 4 are arranged in parallel, the diameter of each guide roller 4 is not required to be increased, and the requirement of the transport height; in addition, the arrangement of the first limiting mechanism 2 and the second limiting mechanism 3 can avoid the jumping of the lead, and the lead is effectively ensured to be conveyed into the paying-off reel along each guide roller 4.
Referring to fig. 5, in the present embodiment, which shows a preferred structure of the supporting device, the supporting device 1 may include: a support shaft 11 and two support plates 12. Wherein, the two support plates 12 are arranged in parallel, and a preset distance is arranged between the two support plates 12. In specific implementation, the preset distance may be determined according to an actual situation, and this embodiment does not limit this. The first limiting mechanism 2 and the second limiting mechanism 3 are both connected with the supporting plate 12.
The support shaft 11 is disposed horizontally and connected to the bottom portions of the two support plates 12, specifically, the support shaft 11 is disposed vertically to the two support plates 12, and the support shaft 11 is connected to the bottom portions of the two support plates 12. In order to better connect the support shaft 11 with the two support plates 12, the bottom of each support plate 12 may be provided with an arc-shaped opening, the arc of which matches the diameter of the support shaft 11, and the two support plates 12 are both connected with the support shaft 11 through the arc-shaped openings.
Each guide roller 4 is disposed between the two support plates 12, and both ends of each guide roller 4 are rotatably connected to the two support plates 12 one by one, respectively. Specifically, each guide roller 4 is transversely arranged between two support plates 12, the axis of each guide roller 4 is perpendicular to the central axis of each support plate 12, and each guide roller 4 is parallel to the support shaft 11. One end of each guide roller 4 is rotatably connected to one of the support plates 12, and the other end of each guide roller 4 is rotatably connected to the other support plate 12.
It can be seen that, in the present embodiment, the supporting device 1 has a simple structure, and can support each guide roller 4, and the rolling of each guide roller 4 is not limited, so as to ensure the normal operation of each guide roller 4.
Referring to fig. 5 and 6, another preferred construction of the support device is shown. As shown, the supporting device 1 may include: a support shaft 11, a third limiting mechanism 13 and two support plates 12. Wherein, the two support plates 12 are arranged in parallel, and a preset distance is arranged between the two support plates 12. In specific implementation, the preset distance may be determined according to an actual situation, and this embodiment does not limit this. The first limiting mechanism 2 and the second limiting mechanism 3 are both connected with the supporting plate 12.
The support shaft 11 is provided transversely and rotatably connected to the bottom portions (lower portions shown in fig. 7) of the two support plates 12, specifically, the support shaft 11 is disposed perpendicularly to the two support plates 12, and the support shaft 11 is rotatably connected to the bottom portions of the two support plates 12.
Each guide roller 4 is disposed between the two support plates 12, and both ends of each guide roller 4 are rotatably connected to the two support plates 12 one by one, respectively. Specifically, each guide roller 4 is transversely arranged between two support plates 12, the axis of each guide roller 4 is perpendicular to the central axis of each support plate 12, and each guide roller 4 is parallel to the support shaft 11. One end of each guide roller 4 is rotatably connected to one of the support plates 12, and the other end of each guide roller 4 is rotatably connected to the other support plate 12.
Since the supporting shaft 11 is rotatably connected to the bottom portions of the two supporting plates 12, the third limiting mechanism 13 is configured to limit the two supporting plates 12 to rotate along the supporting shaft 11 within a first preset angle, that is, the third limiting mechanism 13 is configured to limit the rotating range of the two supporting plates 12 relative to the supporting shaft 11, so that the rotation of the two supporting plates 12 is limited within a certain range. In specific implementation, the first preset angle may be determined according to an actual situation, and this embodiment does not limit this.
It can be seen that, in the embodiment, the supporting shaft 11 is rotatably connected with the bottoms of the two supporting plates 12, so that the two supporting plates 12 can rotate along the supporting shaft 11, and further drive each guide roller 4 to rotate, thereby better adapting to the bending radian of the wires, reducing the bending stress of the wires, ensuring the smooth conveying of the wires, and being beneficial to protecting the wires; in order to prevent the two support plates 12 from rotating arbitrarily along the support shaft 11, the third limiting mechanism 13 limits the two support plates 12 to rotate within a first preset angle, so that the two support plates 12 can rotate around the support shaft 11 within the first preset angle to reduce the bending of the wires.
With continued reference to fig. 5 and 6, in the above embodiment, the third limiting mechanism 13 may include: a stopper plate 131 and a stopper rod 132. Wherein, a notch 121 is arranged at the bottom of each supporting plate 12 corresponding to the supporting shaft 11, the shape of the notch 121 is matched with the shape of the supporting shaft 11, and the notch 121 is contacted with the supporting shaft 11. Specifically, two support plates 12 are provided with notches 121, two support plates 12 are erected on support shaft 11 through notches 121, and two notches 121 are in close contact with support shaft 11, and the contact surface between notches 121 and support shaft 11 is set smoothly. In the present embodiment, the supporting shaft 11 is circular, and the notch 121 is a U-shaped notch.
Since the two support plates 12 have a predetermined distance therebetween, the position limiting plate 131 is horizontally disposed between the two support plates 12, the position limiting plate 131 is vertically disposed to the two support plates 12, the position limiting plate 131 is parallel to each guide roller 4, and the position limiting plate 131 is disposed below each guide roller 4 (with respect to fig. 7). The two ends of the limiting plate 131 are connected with the notches 121 of the two supporting plates 12 in a one-to-one correspondence. Specifically, one end of the position restriction plate 131 is connected to the notch 121 of one support plate 12, and the other end of the position restriction plate 131 is connected to the notch 121 of the other support plate 12. The position limiting plate 131 is in contact with the supporting shaft 11, and the two supporting plates 12 are not only erected on the supporting shaft 11 through the notches 121, but also erected on the supporting shaft 11 through the position limiting plate 131. The shape of the contact part of the limiting plate 131 and the supporting shaft 11 is matched with the shape of the supporting shaft, so that the limiting plate 131 is better contacted with the supporting shaft 11 without influencing the rotation between the limiting plate 131 and the supporting shaft 11, and the contact surface of the limiting plate 131 and the supporting shaft 11 is smooth. In the embodiment, the supporting shaft 11 is circular, and the position limiting plate 131 may be circular or U-shaped. Preferably, the position limiting plate 131 is a U-shaped plate, which is easy to install.
An opening 1311 is opened at a predetermined position of the position limiting plate 131, and the opening 1311 has a predetermined width. One end of the stopper rod 132 is connected to the support shaft 11, and the other end of the stopper rod 132 is placed in the opening 1311. Specifically, the opening 1311 penetrates the plate thickness of the stopper plate 131. The predetermined width of the opening 1311 corresponds to the first predetermined angle, so that the position-limiting plate 131 can rotate within the width of the opening 1311, that is, the position-limiting plate 131 can rotate within the first predetermined angle, and further the two support plates 12 can be driven to rotate within the first predetermined angle. The stopper rod 132 serves to limit the angle of rotation of the stopper plate 131, preventing any rotation between the stopper plate 131 and the support shaft 11.
It can be seen that, in this embodiment, the two support plates 12 contact with the support shaft 11 through the notch 121 to realize the relative rotation between the two support plates 12 and the support shaft 11, and the limiting rod 132 is disposed in the opening 1311 of the limiting plate 131, so that the limiting rod 132 plays a role in limiting the limiting plate 131, and the limiting plate 131 is prevented from rotating around the support shaft 11 at will, that is, the two support plates 12 are prevented from rotating around the support shaft 11 at will, and meanwhile, the opening 1311 has a preset width, and the preset width can limit the rotation of the limiting plate 131 within a certain range, and corresponds to the first angle, so that the two support plates 12 are limited to rotate within the first preset angle, and the structure is simple and convenient to implement.
With continued reference to fig. 5 and 6, in the above embodiment, the openings 1311 are formed at two symmetrical preset positions of the limiting plate 131, and each opening 1311 has a preset width. Specifically, the two preset positions are symmetrically arranged, each opening 1311 penetrates through the plate thickness of the limit plate 131, and the preset width of each opening 1311 is the same. In specific implementation, the preset width corresponds to the first preset angle.
The limiting rod 132 penetrates through the supporting shaft 11, and two ends of the limiting rod 132 are disposed outside the supporting shaft 11 and are disposed in the two openings 1311 in a one-to-one correspondence manner. Specifically, the limiting rod 132 is inserted into the supporting shaft 11, two ends of the limiting rod 132 extend out of the supporting shaft 11, and two ends of the limiting rod 132 are in one-to-one correspondence with the two openings 1311.
It can be seen that, in the present embodiment, the structure of the limiting plate 131 and the limiting rod 132 is simple and easy to operate.

Each guide unit may include: a connecting component 5, a fourth limiting mechanism and a guide roller group 6. Each guide roller group 6 comprises two adjacent guide rollers 4, when the number of the guide rollers 4 is at least two and is even, the M guide rollers 4 form M/2 guide roller groups 6 arranged side by side, and the guide roller groups 6 are sequentially arranged.
Each of the connecting members 5 is rotatably connected to a corresponding one of the guide roller sets 6, and each of the connecting members 5 is rotatably connected to two support plates 12. In particular, the connecting assembly 5 in each guide unit is rotatably connected with two support plates 12, so that the connecting assembly 5 can rotate relative to the support plates 12. And, the connecting assembly 5 in each guide unit is rotatably connected with the guide roller set 6 in the guide unit so that the guide roller set 6 can rotate relative to the connecting assembly 5.
Each fourth limiting mechanism corresponds to one connecting assembly 5, and each fourth limiting mechanism is used for limiting the corresponding connecting assembly 5 to rotate within a second preset angle. Specifically, the fourth limiting mechanism in each guide unit corresponds to the connecting assembly 5 in the guide unit, and since the connecting assembly 5 is rotatably connected with the two support plates 12, the fourth limiting mechanism limits the rotation amplitude of the connecting assembly 5 so as to limit the rotation of the connecting assembly 5 within the second preset angle.
For any one guide unit, the connecting assembly 5, the guide roller group 6 and the fourth limiting mechanism are in one-to-one correspondence, and the connecting assembly 5 is rotatably connected with the guide roller group 6, that is, the connecting assembly 5 is rotatably connected with the two guide rollers 4 in the guide roller group 6. The connecting assembly 5 is rotatably connected with the two support plates 12, and a fourth limiting mechanism corresponds to the connecting assembly 5 to limit the rotation amplitude of the connecting assembly 5. The structures of the guide units are the same, and the guide units are sequentially arranged between the two support plates 12 in order.
