Description

Technical Field

[0001] This utility model relates to the field of guide wheels, specifically a guide component for the production of micro-enameled wire. Background Technology

[0002] In the production process of fine enameled wire, the guiding component plays a crucial role. The guide wheel is a key component of the guiding component, and its main function is to guide the wire body to be transported stably along a predetermined path, ensuring the smooth progress of the production process.

[0003] However, in actual production, the guide wheel is in direct contact with the production line. During long-term operation, the surface of the guide wheel is easily worn due to friction between the line and the guide wheel. Therefore, developing a guide assembly for micro-enameled wire production that allows for easy replacement of wear-resistant sleeves is of significant practical importance. Utility Model Content

[0004] The purpose of this invention is to provide a micro-enameled wire production guide component to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a micro-enameled wire production guide assembly, comprising a guide wheel, one end of which is fitted with a wear-resistant sleeve and a retaining ring, the wear-resistant sleeve being clamped between the retaining ring and the other side plate of the guide wheel, and one end of the guide wheel being provided with a screw connection structure, the screw connection structure fixing the wear-resistant sleeve and the retaining ring to one end of the guide wheel.

[0006] Preferably, the guide wheel is a T-shaped annular plate, and one end of the guide wheel has a side groove, which is an annular groove. The wear-resistant sleeve is a T-shaped round tube, which is fitted behind the guide wheel, with one end of the wear-resistant sleeve inserted into the side groove.

[0007] Preferably, the other end of the wear-resistant sleeve is integrally formed with a plug ring, which is inserted into a slot at the other end of the guide wheel, and the slot is an annular groove.

[0008] Preferably, the retaining ring is sleeved in the side groove, and a reserved groove is opened on the side of the retaining ring away from the wear-resistant sleeve. The reserved groove is an annular groove, and the screw connection structure is located inside the reserved groove.

[0009] Preferably, one end of the wear-resistant sleeve is provided with multiple through holes II, and the surface of the reserved groove is provided with multiple through holes I. Through holes I and through holes II correspond one to one, and through holes I and through holes II allow the screw connection structure to pass through.

[0010] Preferably, the screwed structure includes a screw and a nut. The screw passes through the first through hole and the second through hole and is fixed to the surface of the reserved groove. The nut is screwed onto the end of the screw away from the wear-resistant sleeve.

[0011] Preferably, a rubber sealing sheet is fixed to the outer ring surface of the reserved groove, and the inner ring opening of the rubber sealing sheet is sleeved on the inner ring surface of the reserved groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model proposes a micro-enameled wire production guide assembly that achieves convenient replacement of the wear-resistant sleeve through a unique structural design. During replacement, simply fold the rubber seal outwards from its inner ring to expose the pre-drilled groove, then unscrew the nut, sequentially remove the retaining ring and wear-resistant sleeve, install the new wear-resistant sleeve and retaining ring, and finally tighten the nut and fold the rubber seal back to complete the replacement process. The entire operation is simple and easy to understand, requiring no complex tools or professional skills, greatly shortening replacement time and improving production efficiency. The design of replacing the wear-resistant sleeve separately avoids the need to replace the entire wheel body due to wear-resistant sleeve damage. The wear-resistant sleeve is relatively inexpensive compared to the wheel body; replacing only the wear-resistant sleeve restores the guide assembly to normal use, effectively reducing production costs and improving the company's economic benefits.

[0014] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] Please see Figures 1-5This utility model provides a technical solution: a micro-enameled wire production guide assembly, including a guide wheel 1. One end of the guide wheel 1 is fitted with a wear-resistant sleeve 3 and a retaining ring 6. The wear-resistant sleeve 3 is clamped between the retaining ring 6 and the other side plate of the guide wheel 1. One end of the guide wheel 1 has a screw connection structure that fixes the wear-resistant sleeve 3 and the retaining ring 6 to one end of the guide wheel 1. When the surface of the wear-resistant sleeve 3 is scratched and shows obvious damage, in order to prevent the sharp edges at the damaged area from scratching the conveyed wire, the wear-resistant sleeve 3 needs to be replaced in time. After loosening the screw connection structure, the retaining ring 6 and the wear-resistant sleeve 3 are pulled away from one end of the guide wheel 1. After the new wear-resistant sleeve 3 is fitted onto the end of the guide wheel 1, the retaining ring 6 is fitted onto the end of the guide wheel 1 to clamp the wear-resistant sleeve 3, and the screw connection structure is tightened to complete the assembly. Replacing the wear-resistant sleeve 3 separately avoids replacing the entire wheel body.

[0016] The material selection for wear-resistant sleeve 3 should refer to the following requirements: If the equipment operating temperature is ≤155℃ and high-frequency winding is required: polyurethane or nylon composite coating material should be preferred to balance wear resistance and cost. If the equipment operating temperature is >155℃ or anti-corona performance is required: polyamide-imide substrate should be selected to meet the requirements of high temperature resistance and electrical stability. If solvent resistance and scratch resistance are required: nylon composite coating (such as polyester / nylon) can provide additional protection and extend service life.

[0017] Based on the actual operating conditions of the micro-enameled wire guide assembly (low vibration, frequent disassembly and assembly, temperature resistance ≤150℃), the following combined measures can be adopted to prevent loosening of screw 10 and nut 11: Prioritize the use of locking nuts (nylon inserts): This simplifies the installation process while meeting the requirements for anti-loosening and reusability. Supplement with thread-locking adhesive: Apply a small amount of Loctite 243 adhesive to the surface of the locking nut to further improve reliability. Control the tightening torque: Use a torque wrench to tighten to the recommended value (e.g., 5 N·m) to ensure consistent preload. If the assembly experiences significant vibration or requires long-term operation, the combination of a stop washer and thread-locking adhesive can be used instead, sacrificing a small amount of ease of disassembly and assembly in exchange for higher anti-loosening stability.

[0018] To facilitate convenient replacement of the wear-resistant sleeve 3, the following proposed method is proposed: The guide wheel 1 is a T-shaped annular plate. One end of the guide wheel 1 has a side groove 2, which is an annular groove. The wear-resistant sleeve 3 is a T-shaped cylindrical tube. The wear-resistant sleeve 3 is fitted onto the guide wheel 1, and one end of the wear-resistant sleeve 3 is inserted into the side groove 2. The other end of the wear-resistant sleeve 3 has an integrally formed insert ring 4, which is inserted into a slot 5 at the other end of the guide wheel 1. The slot 5 is an annular groove. The retaining ring 6 is fitted into the side groove 2, and the side of the retaining ring 6 away from the wear-resistant sleeve 3 has a reserved groove 7. The reserved groove 7 is an annular groove, and the screw connection structure is located inside the reserved groove 7. Multiple through holes 9 are provided at one end of the wear-resistant sleeve 3, and multiple through holes 8 are provided on the surface of the reserved groove 7. Through holes 8 and 9 correspond one-to-one, allowing the screw connection structure to pass through. The screw connection structure includes a screw rod 10 and a nut 11. The screw rod 10 passes through through holes 8 and 9 and is fixed to the surface of the reserved groove 7. The nut 11 is screwed onto the end of the screw rod 10 away from the wear-resistant sleeve 3. A rubber sealing plate 12 is fixed to the outer annular surface of the reserved groove 7, and the inner annular opening of the rubber sealing plate 12 is fitted onto the inner annular surface of the reserved groove 7.

[0019] When replacing the wear-resistant sleeve 3, turn the rubber seal 12 outward from the inner ring opening of the rubber seal 12. At this time, the reserved groove 7 is exposed. Remove the nut 11 from the end of the screw 10. Then, pull the retaining ring 6 and the wear-resistant sleeve 3 out from the end of the guide wheel 1 in sequence. Then, put a new set of wear-resistant sleeves 3 on the guide wheel 1 and push the wear-resistant sleeve 3 until the insertion ring 4 at the end of the wear-resistant sleeve 3 is inserted into the slot 5 and the screw 10 passes through the corresponding through hole 2 9. Then, put the retaining ring 6 in the side groove 2 and make the screw 10 pass through the through hole 1 8. Then, screw the nut 11 back onto the end of the screw 10. Finally, turn the rubber seal 12 back to cover the reserved groove 7.

[0020] Method for replacing the wear-resistant sleeve in the guide assembly for micro-enameled wire production: Fold the rubber seal 12 outwards from its inner ring opening to fully expose the pre-drilled groove 7. Use a suitable tool to unscrew the nut 11 from the end of the screw 10. Remove the retaining ring and wear-resistant sleeve: Sequentially remove the retaining ring 6 and wear-resistant sleeve 3 from the end of the guide wheel 1. During removal, ensure smooth movement to avoid damage to the guide wheel 1 and other components. Place a new set of wear-resistant sleeves 3 onto the guide wheel 1. Slowly push the wear-resistant sleeve 3 until the insertion ring 4 at the end of the wear-resistant sleeve 3 is accurately inserted into the slot 5 at the other end of the guide wheel 1, while ensuring that the screw 10 passes through the corresponding perforation 9 on the wear-resistant sleeve 3. Place the retaining ring 6 into the side groove 2 at one end of the guide wheel 1, ensuring that the screw 10 passes through the perforation 8 on the surface of the pre-drilled groove 7 on the retaining ring 6. Using a tool, tighten the nut 11 back onto the end of the screw 10, ensuring that the nut 11 is securely tightened, thus firmly fixing the retaining ring 6 and the wear-resistant sleeve 3 onto the guide wheel 1. Flip the rubber sealing plate 12 back so that it re-covers the reserved groove 7, ensuring that the rubber sealing plate 12 completely covers the reserved groove 7 for protection. By following the above steps, the replacement of the wear-resistant sleeve 3 can be completed, preventing the conveyor line from being scratched due to damage to the wear-resistant sleeve 3. At the same time, replacing the wear-resistant sleeve 3 separately avoids replacing the entire wheel body, reducing costs and replacement difficulty.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
