[0002] The laying of wind turbine blade fabrics (such as carbon fiber and glass fiber fabrics) is a key step in blade manufacturing, and the unwinding device is the core equipment for achieving efficient and high-quality laying.

[0003] Traditional wind turbine blade fabric laying and unwinding devices cannot automatically adjust the unwinding speed while maintaining the fabric transmission tension. They usually rely on manual intervention based on the operator's experience, which not only results in delayed adjustment and poor control accuracy, but also increases labor costs and labor intensity. To solve the above problems, we provide an unwinding device for wind turbine blade fabric laying. Utility Model Content

[0004] The purpose of this invention is to provide an unwinding device for laying wind turbine blade fabric, so as to solve the problem mentioned in the background art that traditional wind turbine blade fabric laying unwinding devices cannot automatically adjust the unwinding speed while maintaining the fabric transmission tension.

[0011] This utility model has the following beneficial effects: This device allows the eccentric block to rotate and store energy after the user installs the fabric loops and threads the fabric. This maintains the tension during fabric transport. When the fabric tension changes, the eccentric block triggers the first or second sensor, which in turn adjusts the unwinding speed of the unwinding mechanism. This achieves automatic acceleration of unwinding when the tension increases and automatic deceleration when the tension decreases. This design not only effectively ensures the stability and tension uniformity of fabric transport but also achieves automatic adaptive adjustment of the unwinding speed, improving laying efficiency and fabric quality while reducing the need for manual intervention.

Detailed Implementation

[0014] The present invention will be further described in detail below with reference to the accompanying drawings.

[0015] Example 1: refer to Figure 1-6 A wind turbine blade fabric laying unwinding device includes a support platform 1, support rods 2 on both sides of the support platform 1, an unwinding mechanism 3 bolted to the top of the support rods 2, a first adjusting roller 4 on the top of the support platform 1, connecting frames 5 rotatably connected to both ends of the first adjusting roller 4, a second adjusting roller 6 rotatably connected between the two connecting frames 5, a rotating shaft 7 fixedly connected to one side of the connecting frame 5, a first support seat 8 rotatably connected to the surface of the rotating shaft 7, the back of the first support seat 8 bolted to the support rod 2, an eccentric block 9 fixedly sleeved on the surface of the rotating shaft 7, a screw 10 fixedly connected to one side of the eccentric block 9, a sensing plate 11 sleeved on the surface of the screw 10, a fixing nut 12 threadedly connected to the surface of the screw 10, a bracket 13 on one side of the support rod 2, a through groove 14 opened inside the bracket 13, and a first sensor 15 and a second sensor 16 respectively sleeved inside the through groove 14.

[0016] Specifically, after the user installs the fabric loops and threads the fabric, the device drives the eccentric block 9 to rotate and store energy by relying on the traction force of the fabric, thereby continuously maintaining the tension during the fabric transmission process. When the fabric tension changes, the eccentric block 9 drives the sensing plate 11 to trigger the first sensor 15 or the second sensor 16 respectively, and the controller adjusts the unwinding speed of the unwinding mechanism 3 accordingly, realizing automatic acceleration of unwinding when the tension becomes tight and automatic deceleration of unwinding when the tension becomes loose. This design not only effectively ensures the stability and tension uniformity of fabric transmission, but also realizes automatic adaptive adjustment of the unwinding speed, improving laying efficiency and fabric quality, while reducing the need for manual intervention.

[0017] refer to Figure 6 The surfaces of the first sensor 15 and the second sensor 16 are both threaded with a first nut 17, and the surfaces of the first sensor 15 and the second sensor 16 are both threaded with a second nut 18. By setting the first nut 17 and the second nut 18, the first sensor 15 and the second sensor 16 can be fixedly installed, and the sensing distance can also be adjusted.

[0018] refer to Figure 6 The bracket 13 is fitted with a fixing bolt 25 inside. One end of the fixing bolt 25 is threaded to the support rod 2. By setting the fixing bolt 25, the bracket 13 can be effectively installed.

[0019] refer to Figure 3The top of the support platform 1 is provided with a first transmission roller 19, and the two ends of the first transmission roller 19 are rotatably connected to a second support seat 20. The front of the second support seat 20 is bolted to the support rod 2. By setting the first transmission roller 19, the fabric can be effectively guided and transmitted.

[0020] refer to Figure 3 The top of the support platform 1 is provided with a second transmission roller 21. Both ends of the second transmission roller 21 are rotatably connected to a third support seat 22. The back of the third support seat 22 is bolted to the support rod 2. By setting the second transmission roller 21, the fabric can be effectively guided and transmitted.

[0021] refer to Figure 3 A mounting base 23 is fixedly sleeved on one side of the support rod 2. A mounting bolt 24 is sleeved inside the mounting base 23. One side of the mounting bolt 24 is threadedly connected to the support platform 1. By setting the mounting base 23 and the mounting bolt 24, the support rod 2 and the support platform 1 can be effectively fixed and installed.

[0022] Brief description of usage: After the user installs the fabric loop with the unwinding mechanism 3, one end of the fabric is passed sequentially through the first transmission roller 19, the first adjusting roller 4, the second adjusting roller 6, and the second transmission roller 21. The traction force at one end of the fabric drives the eccentric block 9 to rotate. The eccentric block 9 drives the rotating shaft 7 to rotate inside the first support base 8. At the same time, the connecting frame 5 drives the eccentric block 9 to deflect and store energy. When the tension of the fabric loop becomes tighter, the rotating shaft 7 drives the eccentric block 9 to continue rotating. Simultaneously, the eccentric block 9 drives the sensing plate 11 to reach the sensing range of the second sensor 16, causing the second sensor 16 to transmit a signal to the controller for control. The unwinding mechanism 3 gradually increases the unwinding speed, causing the eccentric block 9 to drive the sensing plate 11 back to the normal working range. When the tension of the fabric loop loosens, the eccentric block 9 drives the rotating shaft 7 to rotate by gravity. By setting the eccentric block 9, the tension of the fabric transmission can be maintained at all times. At the same time, the eccentric block 9 drives the sensing plate 11 to the sensing range of the first sensor 15, so that the first sensor 15 transmits a signal to the controller to control the unwinding mechanism 3 to gradually reduce the unwinding speed, so that the eccentric block 9 drives the sensing plate 11 back to the normal working range. Thus, the unwinding speed can be automatically adjusted while maintaining the tension of the fabric transmission.
