Description

Technical Field

[0001] This utility model relates to the field of yarn production technology, specifically to a device for an oiling roller to drive a bundling wheel to rotate. Background Technology

[0002] In the production of high-end wind power yarn, yarn quality is the core factor determining the final composite material performance. Among these factors, the sizing agent coating process is a crucial step in improving the compatibility between the yarn and the resin matrix and protecting the fibers. However, a key piece of equipment in this process—the bundling wheel—has long plagued manufacturers, becoming a bottleneck affecting product qualification rates.

[0003] One of the core processes in a wind turbine yarn production line is that after multiple bundles of raw yarn are fully impregnated in a sizing agent tank, they need to be gathered, guided, and tension-controlled by a bundling wheel to facilitate subsequent drying and winding. However, as the yarn passes through the bundling wheel, it experiences continuous friction and scraping against the wheel groove surface. This friction scrapes off tiny fibers, known as fuzz (commonly called "fly hairs" or "feathers"), from the yarn surface and adheres to the bundling wheel. This yarn containing impurities not only affects the appearance but also severely damages the interfacial bonding between the fiber and the resin matrix, leading to a decline in the mechanical properties of the final composite material components such as wind turbine blades, posing a significant safety hazard.

[0004] To address this thorny issue, manufacturers currently employ the following two methods, but both have significant drawbacks:

[0005] Option 1: Shorten the replacement cycle of the cluster wheels

[0006] Operating Method: The replacement cycle of the clustering wheels is drastically shortened from the designed value (e.g., 3 months) to 1 month or even less. When noticeable fuzz appears on the wheel surface, the machine is immediately stopped and a new clustering wheel is replaced. However, this method severely reduces production efficiency: frequent replacement of clustering wheels means frequent production line shutdowns. Each shutdown involves a series of processes such as equipment cooling, disassembly, installation, debugging, and reheating, resulting in significant production time loss, disrupting the production rhythm, and reducing the effective operating rate of the equipment. It also increases operating costs: frequent replacements lead to a surge in the consumption of spare parts (graphite clustering wheels), directly driving up the procurement cost of spare parts. Simultaneously, energy consumption during downtime (e.g., reheating the impregnating agent tank and drying oven) and labor costs also increase. Maintenance workload is high: frequent disassembly and assembly operations place higher demands on equipment maintenance personnel, increasing the labor intensity of maintenance and potential operational risks.

[0007] Option 2: The motor drives the cluster wheel to rotate.

[0008] Operating Method: A separate motor drives the bundling wheel to rotate, creating "rolling friction" between it and the yarn instead of the original "sliding friction," reducing the lint adhering to the bundling wheel. However, this method poses a significant safety hazard: this is the most fatal flaw of the solution. The bundling wheel is typically located near high-voltage (thousands or even tens of thousands of volts) electrostatic discharge equipment, or it may itself be charged due to friction. Directly connecting the motor to the rotating bundling wheel can easily lead to high-voltage electricity being conducted to the ground through the drive shaft and motor housing, posing a fatal threat of electric shock to operators. Even with insulation measures, the reliability of insulation is difficult to guarantee in humid and dusty production environments, posing an extremely high risk. Furthermore, this method also suffers from structural complexity and reduced reliability: adding an independent drive system to already complex spinning equipment further complicates the equipment structure and increases potential points of failure. Failures in the added components such as the motor, couplings, and bearings can also cause unexpected shutdowns of the production line.

[0009] In conclusion, the two existing mainstream solutions—shortening replacement cycles and motor-driven rotation—sacrifice efficiency and introduce safety risks in exchange for lint control, respectively, and neither is an ideal or sustainable solution. Faced with this industry-wide challenge, a more fundamental and safer solution is urgently needed. Utility Model Content

[0032] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model.

[0033] Example 1

[0034] like Figure 9-10 As shown, this embodiment provides a device for rotating an oiling roller to drive a cluster wheel, including a transmission kit 1 disposed at one end of the rotating shaft 1 of the oiling roller. The transmission kit 1 is flexibly connected to the transmission kit 2 via a flexible spring rod 4. The transmission kit 2 is connected to the cluster wheel, so that the rotating shaft 1 of the oiling roller drives the cluster wheel to rotate through the transmission kit 1 and the transmission kit 2.

[0035] Specifically, such as Figure 1-2 As shown, the transmission assembly includes a plug 2, which is fixed to one end of the rotating shaft 1. The plug 2 has a through hole 201, and a connecting shaft is placed inside the through hole 201; as shown... Figure 3-4 As shown, a through hole 303 is provided inside the connecting shaft, and the connecting shaft includes a thick section 301 and a thin section 302, as shown. Figure 7 As shown, the rotating shaft 1 is fixed inside the thick section 301 of the connecting shaft. The specific method of fixing the rotating shaft 1 within the thick section 301 of the connecting shaft is as follows: Figure 1-5As shown in Figure 7, a through hole 202 is provided on the side wall of the plug 2. A threaded hole 304 is provided at the through hole 202 in the thick section 301 of the connecting shaft. A set screw 7 is threaded into the threaded hole 304. A groove 103 is provided at the set screw 7 in the thick section 301 of the connecting shaft. The set screw 7 abuts in the groove 103, thereby fixing the shaft 1 in the thick section 301 of the connecting shaft.

[0036] like Figure 9-10 As shown, plug 2 achieves a soft connection with transmission kit 2 via flexible spring rod 4, as... Figure 8 As shown, one end of the flexible connecting spring rod 4 is provided with a plug rod 5, which is inserted into the thin section 302 of the connecting shaft, enabling the connecting shaft to drive the plug rod 5 to rotate. The rotating shaft 1 of the oiling roller rotates under the drive of the motor, thereby driving the connecting shaft fixed on the rotating shaft 1 to rotate, which in turn drives the flexible connecting spring rod 4, which is inserted into the connecting shaft via the plug rod 5, to rotate. Finally, the rotation of the cluster wheel is achieved through the rotation of the transmission kit 2.

[0037] And, as Figure 9 As shown, the end of the plug-in 2 that connects to the flexible connecting spring rod 4 has an external thread. A protective sleeve 9 is fitted over the flexible connecting spring rod 4, and a nut 10 is provided at one end of the protective sleeve 9. The protective sleeve 9 is threaded onto the plug-in 2. The protective sleeve 9, which is located outside the flexible connecting spring rod 4, serves to protect the flexible connecting spring rod 4.

[0038] Transmission assembly two includes a worm gear connected to a worm wheel, which is mounted on a rotating shaft two connected to a cluster wheel. The worm gear and worm wheel are enclosed by a housing 11, such as... Figure 10 As shown, a threaded rod 12 is provided on the outer shell 11, and a nut 13 is provided on the other end of the protective sleeve 9. The protective sleeve 9 is threadedly connected to the threaded rod 12. A plug rod 6 is provided on the other end of the flexible connecting spring rod 4. The plug rod 6 is inserted into the worm gear, so that the rotating shaft 1 can drive the worm gear to rotate through the flexible connecting spring rod 4, and finally drive the rotating shaft 2 to rotate through the worm wheel to realize the rotation of the cluster wheel.

[0039] Working principle:

[0040] During normal operation, the motor drives the rotating shaft 1 of the oiling roller to rotate. Since the rotating shaft 1 is fixed in the thick section 301 of the connecting shaft by the set screw 7, it can drive the connecting shaft to rotate. The insert rod 5 inserted in the thin section 302 of the connecting shaft rotates accordingly, thereby realizing the rotation of the flexible connecting spring rod 4. Under the drive of the flexible connecting spring rod 4, the worm gear rotates with the insert rod 6 on the flexible connecting spring rod 4, thereby driving the worm wheel to rotate, and finally realizing that the rotating shaft 2 drives the bundling wheel to rotate. The device of this embodiment uses the rotation of the existing oiling roller to drive the rotation of the bundling wheel, thereby reducing the friction of the yarn at the bundling wheel, reducing the generation of fuzz, and extending the online time of the bundling wheel from the original 5 hours to 168 hours.

[0041] Example 2

[0042] Based on Example 1, such as Figure 5 , 7 As shown, the existing coating roller's rotating shaft 1 includes a coarse section 101 and a fine section 102, with the fine section 102 extending into the connecting shaft and fixed within the coarse section 301; as Figure 6-7 As shown, a bushing 8 is provided inside the insert 2, and the bushing 8 fits over the thick section 101 of the rotating shaft 1. When assembling the transmission kit, the connecting shaft is first placed into the insert 2, and then the bushing 8 is hammered into the insert 2 to fix it in place. The positional relationship between the connecting shaft and the bushing 8 is such that the end of the thick section 301 of the connecting shaft extends into the bushing 8 but does not contact the inner wall of the bushing 8. Because the bushing 8 is tightly fitted inside the insert 2, it does not rotate when the rotating shaft 1 rotates, thus providing rotational support. It can be made of wear-resistant copper alloy.
