[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a roll-up and unwinding rack for carbon fiber cloth production, comprising a base 1 and a connecting rod 12, a U-shaped frame 3 is fixedly connected to the left side of the base 1, an opening groove 4 is provided on the inner top of the U-shaped frame 3, a servo motor 5 is fixedly connected to the front side of the U-shaped frame 3, an output end of the servo motor 5 passes through the opening groove 4 and is fixedly connected to a bidirectional screw rod 6, a movable block 7 is threadedly connected to the front and rear sides of the outer wall of the bidirectional screw rod 6, a first movable shaft 8 is fixedly connected to the bottom of the movable block 7, a hollow frame 9 is provided on the inner side of the U-shaped frame 3, The front and rear sides of the top of the hollow frame 9 are fixedly connected with a U-shaped plate 10, the inside of the U-shaped plate 10 is rotatably connected with a second movable shaft 11, and the two second movable shafts 11 are respectively connected to the corresponding first movable shaft 8 through a connecting rod 12, and the inner side of the hollow frame 9 is rotatably connected with a rotating roller 13, and a limiting mechanism 2 is provided on the right side of the front end of the base 1, and the setting height of the rotating roller 13 is less than the setting height of the winding roller 208, and the rear end of the bidirectional screw rod 6 is rotatably connected to the inner rear side of the opening slot 4, and the two movable blocks 7 are both slidably connected to the inside of the opening slot 4;

[0030] Specifically, the bidirectional screw rod 6 can be driven to rotate by the servo motor 5. When the bidirectional screw rod 6 starts to rotate, the movable block 7 thereon will move toward the middle accordingly. The accuracy of this action is crucial to the stability of the entire system. At the same time, the first movable shaft 8 will rotate with the rotation of the bidirectional screw rod 6. Driven by the first movable shaft 8, the second movable shaft 11 will also rotate through the transmission of the connecting rod 12. This series of transmission designs enables the power to be efficiently transmitted, thereby driving the operation of the entire system. With the rotation of the second movable shaft 11, the hollow frame 9 will move downward, and this action is very important for the shrinkage of the carbon fiber cloth. The winding process is crucial. The movement of the hollow frame 9 can ensure that the carbon fiber cloth is always kept in a tensioned state during winding, avoiding uneven or loose winding. In addition, the rotating roller 13 will also move downward with the movement of the hollow frame 9 to squeeze the carbon fiber cloth. This squeezing action not only helps to improve the tightness of the winding, but also ensures that the carbon fiber cloth remains flat during the winding process without wrinkles or distortion, thereby achieving precise control of the carbon fiber cloth during the winding process. This control method ensures that the rolled carbon fiber cloth is evenly wound around the outside of the winding roller 208, laying a solid foundation for subsequent normal use.

[0031] Reference Figure 1 and Figure 2 The limiting mechanism 2 includes a fixed plate 201, which is fixedly connected to the right side of the front end of the base 1, and a hollow rod 202 is rotatably connected to the front side of the fixed plate 201. The rear end of the hollow rod 202 penetrates the fixed plate 201, and a gear 203 is fixedly connected to the outer side of the hollow rod 202. A support plate 204 is fixedly connected to the middle and upper part of the front side of the fixed plate 201, and a T-shaped rod 205 is arranged on the top of the support plate 204. The bottom end of the T-shaped rod 205 penetrates the support plate 204 and is fixedly connected to a gear ring 206, which is meshed with the gear 203. A spring 207 is arranged on the outer side of the T-shaped rod 205, and one end of the spring 207 is fixedly connected to the top of the support plate 204, and the other end of the spring 207 is fixedly connected to the inner top of the T-shaped rod 205;

[0032] Specifically, before the winding work is performed, the T-shaped rod 205 is pulled upwards first. The purpose of this action is to make the gear ring 206 separate from the gear 203. Once the gear ring 206 is separated from the gear 203, we can rotate the hollow rod 202. The hollow rod 202 is connected to the first winding roller 208. Therefore, when the hollow rod 202 rotates, the first winding roller 208 will also rotate accordingly. This rotation process will make the carbon fiber cloth tightly rolled on the winding roller 208 to complete the winding work. After the winding work is completed, the T-shaped rod 205 is released. At this time, the T-shaped rod 20 The spring 207 on the outside plays a role. The elastic force of the spring 207 causes the gear ring 206 to rebound and realign with the position of the gear 203. The purpose of this is to prevent the winding roller 208 from rotating automatically without external interference, thereby maintaining the tightly wound state of the carbon fiber cloth and preventing it from loosening when the unwinding work is not performed. This design not only simplifies the operating steps of the winding work, but also improves the practicality of the device, which not only avoids the production problems that may be caused by the loosening of the carbon fiber cloth, but also improves the working efficiency and product quality of the entire device.

[0033] Reference Figure 2 and Figure 3 The limiting mechanism 2 further includes a winding roller 208, which is arranged on the inner side of the hollow rod 202. The rear side of the outer wall of the hollow rod 202 is threadedly connected with a bolt 209, and the bottom end of the bolt 209 passes through the hollow rod 202 and the winding roller 208 in sequence;

[0034] Specifically, the wound winding roller 208 can be easily disassembled and replaced by the bolt 209, thereby improving the practicality of the device.

[0035] Reference Figure 1 and Figure 2A switch 14 is fixedly connected to the middle and lower part of the front side of the fixed plate 201, and the switch 14 is electrically connected to the servo motor 5. A protective cover 15 is arranged on the outer side of the switch 14, and the top of the protective cover 15 is rotatably connected to the front side of the fixed plate 201 through a rotating shaft;

[0036] Specifically, the operation of the servo motor 5 can be controlled by the switch 14 , and the protective cover 15 can protect the switch 14 from being damaged by external factors.

[0037] Working principle: When using the device, first pass one end of the carbon fiber cloth to be rolled through the bottom of the rotating roller 13, and then connect it to the winding roller 208. At this time, rotating the hollow rod 202 can drive the winding roller 208 to rotate and roll the carbon fiber cloth. Then start the servo motor 5, which can drive the bidirectional screw rod 6 to rotate. The movable block 7 on the bidirectional screw rod 6 will move toward the middle. At this time, the first movable shaft 8 will rotate accordingly, and the second movable shaft 11 will also rotate through the connecting rod 12, so as to drive the hollow frame 9 to move downward, and the rotating roller 13 will also move downward to squeeze the carbon fiber cloth, so that the carbon fiber cloth can be kept in a tensioned state when rolled, so that the rolled carbon fiber cloth can be evenly rolled. The carbon fiber cloth is wound around the outside of the winding roller 208, which will not affect the normal use of the subsequent carbon fiber cloth. Before the winding work is performed, the T-bar 205 is first pulled upward to make the toothed ring 206 disengage from the gear 203. At this time, the hollow rod 202 is rotated to drive the first winding roller 208 to rotate, and the winding roller 208 will rotate accordingly, so that the carbon fiber cloth can be wound. After the winding work is completed, the T-bar 205 is released, and the spring 207 on the outside of the T-bar 205 will drive the toothed ring 206 to rebound to limit the gear 203. The winding roller 208 will not rotate easily, and the carbon fiber cloth on the winding roller 208 will not loosen easily, so as not to affect the unwinding work of the subsequent carbon fiber cloth processing, thereby improving the practicability of the device.
