Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example

[0035] See also Figure 1-Figure 8 As shown, the purpose of this embodiment is to provide a carbon fiber cloth winding device based on double-end alignment, including two device stands 1, a horizontal slide bar 11 is fixedly connected to the top of the two device stands 1, a rotating wheel 12 is installed on the side of the two device stands 1 close to the horizontal slide bar 11, a core mold roller 13 for fixing the core mold is connected between the two rotating wheels 12, a sliding table 14 is slidably provided at the bottom of the horizontal slide bar 11, a vertical plate 15 is fixedly connected to the bottom of the sliding table 14, two extension members 16 are installed on the surface of the vertical plate 15, three pressure rollers 17 for auxiliary limiting the carbon fiber cloth are installed on the side of the two extension members 16 away from the vertical plate 15, an angle adjustment component 2 for adjusting the winding angle is installed on the end of the two extension members 16 close to the vertical plate 15, a winding component 3 is sleeved on the surface of the outer pressure roller 17, and the angle adjustment component 2 and the winding component 3 operate in combination to adjust the tension of the carbon fiber cloth.

[0036] First, the specific structure of the angle adjustment component 2 is disclosed. The angle adjustment component 2 includes a mounting hole 21 provided on the surface of the vertical plate 15. A driven gear 22 is slidably installed inside the mounting hole 21. The extension 16 is located inside the driven gear 22. A driving gear 23 is meshingly installed on the surface of the driven gear 22. The driving gear 23 is movably installed on the side surface of the vertical plate 15 close to the core mold roller 13. The rotating shaft of the driving gear 23 is fixedly connected to the output shaft of the motor 24. The motor 24 is fixedly connected to the other side surface of the vertical plate 15. When the carbon fiber cloth inserted in the extension 16 needs to be adjusted in angle, the motor 24 installed on the other side surface of the vertical plate 15 is started to drive the driving gear 23 fixedly connected to the output shaft of the motor 24 to rotate. The driving gear 23 is meshed and connected with the driven gear 22, so that the driven gear 22 can drive the extension 16 installed inside it to rotate in angle, which is more convenient for adjusting the winding angle of the carbon fiber cloth.

[0037] Next, the specific structure of the winding assembly 3 is disclosed. The winding assembly 3 includes a sleeve rod 31 sleeved on the outer wall of the outer pressure roller 17. The sleeve rod 31 is formed by splicing a first semicircular rod 32 and a second semicircular rod 33. The ends of the first semicircular rod 32 and the second semicircular rod 33 are both installed with side wall mounting parts 34. The insides of two adjacent side wall mounting parts 34 are connected by a mounting shaft 35. The surface of the sleeve rod 31 is provided with a thread groove 36, and the carbon fiber cloth is wound inside the thread groove 36. By using the side wall mounting parts 34 installed at the ends of the first semicircular rod 32 and the second semicircular rod 33, the first semicircular rod 32 and the second semicircular rod 33 can be spliced ​​together to form a sleeve rod 31. By using the thread groove 36 opened on the surface of the sleeve rod 31, the carbon fiber cloth can be wound inside the thread groove 36, so as to achieve the effect of limiting the carbon fiber cloth and reduce the situation where the carbon fiber cloth changes position during the winding process and causes repeated winding.

[0038] Taking into account that the sleeve rod 31 is movably installed on the surface of the outer pressure roller 17, and the pressure roller 17 is in a stationary state when the device is operating as a whole, in order to improve the installation stability of the sleeve rod 31 and reduce the rotation of the sleeve rod 31 on the surface of the pressure roller 17, the first semicircular rod 32 and the second semicircular rod 33 are both provided with positioning grooves 4 on the side close to the pressure roller 17, and the surface of the outer pressure roller 17 is fixedly connected with two positioning blocks 41 that are in contact with the surface of the positioning grooves 4.

[0039] The improvement lies in that: by utilizing the positioning grooves 4 opened on the inner walls of the first semicircular rod 32 and the second semicircular rod 33 and the two positioning blocks 41 fixedly installed on the surface of the outer pressure roller 17, when the sleeve rod 31 is installed, the positioning blocks 41 can be engaged with the positioning grooves 4, which effectively reduces the situation where the sleeve rod 31 rotates on the surface of the pressure roller 17 after installation.

[0040] Since the driven gear 22 is relatively large in size, it has a relatively wide contact with the air. Therefore, impurities are more likely to remain on the surface of the driven gear 22, affecting the normal operation of the driven gear 22. In order to facilitate the operation of the driven gear 22, support rods 5 are fixedly installed on both sides of the vertical plate 15, and gear lubricating cotton 51 for lubricating the surface of the driven gear 22 is movably installed on one side of the two support rods 5 close to the middle of the vertical plate 15.

[0041] The improvement lies in: by utilizing the support rods 5 arranged on both sides of the vertical plate 15, the gear lubricating cotton 51 can be installed at one end of the support rod 5 close to the middle of the vertical plate 15, and the gear lubricating cotton 51 fits with the surface of the driven gear 22. When the driven gear 22 rotates, the outer wall of the driven gear 22 can be lubricated and cleaned, thereby further improving the rotation effect of the driven gear 22.

[0042] Since the device needs to adjust the angle of the sleeve rod 31 when adjusting the tension of the carbon fiber cloth, and the end structure of the threaded groove 36 opened on the surface of the sleeve rod 31 is single, in order to reduce the situation that the carbon fiber cloth is out of the groove when the sleeve rod 31 is adjusting the tension at an angle, a limit buckle 6 is provided on the outer wall of the end of the sleeve rod 31, and a sliding groove 62 is opened on the surface of the sleeve rod 31. A sliding member 61 is slidably provided inside the sliding groove 62, and one end of the sliding member 61 extends out of the sliding groove 62 and is fixedly connected to the surface of the limit buckle 6.

[0043] The improvement lies in that when the sleeve rod 31 follows the pressure roller 17 to adjust the angle of tension, the sliding member 61 slides inside the sliding groove 62 by gravity, and then drives the limiting buckle 6 fixedly connected to the end of the sliding member 61 to slide and block on the surface of the thread groove 36, thereby achieving the effect of limiting the carbon fiber cloth and effectively reducing the situation of the carbon fiber cloth falling out of the groove.

[0044] Taking into account the return of the limit buckle 6 when the pressure roller 17 rotates to return to the horizontal position, in order to improve the return effect of the limit buckle 6 and not affect the normal sliding and winding of the carbon fiber cloth, an elastic member 7 is installed at one end of the sliding member 61 away from the thread groove 36, and the other end of the elastic member 7 is fixedly connected to the inner wall of the sliding groove 62.

[0045] The improvement lies in that when the sleeve rod 31 is in a horizontal position, the limit buckle 6 will slide to the surface of the sleeve rod 31 through the extrusion of the carbon fiber cloth and the pulling of the elastic member 7, without affecting the normal sliding and winding of the carbon fiber cloth.

[0046] The elastic member 7 has the main purpose of assisting in pulling the limit buckle 6 back to its original position when the sleeve rod 31 returns to the horizontal state along with the pressure roller 17. The elastic member 7 is preferably a spiral spring member, and a rubber tube may also be used to achieve the above purpose.

[0047] In summary, the working principle of the present invention is as follows: first, the sliding table 14 sliding at the bottom of the horizontal sliding rod 11 is used to enable the vertical plate 15 to move left and right, and the extension piece 16 and the pressure roller 17 arranged inside the vertical plate 15 can assist the carbon fiber cloth to be pulled and wound on the surface of the core mold roller 13, so as to achieve the effect of carbon fiber cloth winding and molding. When the carbon fiber cloth inserted in the extension piece 16 is wound around the end of the core mold roller 13 and the winding angle needs to be adjusted, the motor 24 installed on the other side surface of the vertical plate 15 is started to drive the driving gear 2 fixedly connected to the output shaft of the motor 24. 3 rotation, the driving gear 23 is meshed and connected with the driven gear 22, so that the driven gear 22 can drive the extension piece 16 installed inside it to rotate at an angle, which is more convenient for adjusting the winding angle of the carbon fiber cloth. The support rods 5 arranged on both sides of the vertical plate 15 are used, so that the gear lubricating cotton 51 can be installed at one end of the support rod 5 close to the middle of the vertical plate 15, and the gear lubricating cotton 51 is in contact with the surface of the driven gear 22. When the driven gear 22 rotates, the outer wall of the driven gear 22 can be lubricated and cleaned, further improving the rotation effect of the driven gear 22;

[0048] By using the side wall mounting member 34 installed at the ends of the first semicircular rod 32 and the second semicircular rod 33, the first semicircular rod 32 and the second semicircular rod 33 can be fitted and spliced ​​to form a sleeve rod 31. By using the thread groove 36 provided on the surface of the sleeve rod 31, the carbon fiber cloth can be wound inside the thread groove 36, so as to achieve the effect of limiting the position of the carbon fiber cloth and reduce the situation where the carbon fiber cloth changes position during the winding process and causes repeated winding.

[0049] When the carbon fiber cloth is wound, in order to improve the quality and performance of the wound product, the starting end and the end of the carbon fiber cloth will be aligned. During the winding process of the carbon fiber cloth, the tension of the carbon fiber cloth can be adjusted to achieve the effect of double-end alignment. When the tension of the carbon fiber cloth needs to be adjusted, the motor 24 is started to drive the driving gear 23 and the driven gear 22 to rotate, so that the extension piece 16 and the three pressure rollers 17 rotate clockwise, driving the sleeve rod 31 to adjust the angle, so that the carbon fiber cloth wound inside the sleeve rod 31 is auxiliary stretched, so as to adjust the tension of the carbon fiber cloth. The angle adjustment method is used to adjust the tension. On the one hand, it reduces the space required for the carbon fiber cloth to be stretched, and on the other hand, it can improve the intuitiveness of the tension adjustment.

[0050] When the sleeve rod 31 follows the pressure roller 17 to adjust the angle of tension, the sliding member 61 uses gravity to slide inside the sliding groove 62, and then drives the limiting buckle 6 fixedly connected to the end of the sliding member 61 to slide and block on the surface of the threaded groove 36, so as to limit the carbon fiber cloth and effectively reduce the situation of the carbon fiber cloth falling out of the groove. When the sleeve rod 31 is in a horizontal position, the limiting buckle 6 will slide to the surface of the sleeve rod 31 through the extrusion of the carbon fiber cloth and the pulling of the elastic member 7, without affecting the normal sliding and winding of the carbon fiber cloth.

The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
