Description

Technical Field

[0001] This utility model belongs to the technical field of chemical fiber equipment, specifically relating to a polyester filament guide assembly. Background Technology

[0002] Polyester industrial yarn refers to high-strength, coarse-denier polyester filaments used in industry. Based on their properties, they can be classified into high-strength low-elongation, high-modulus low-shrinkage, high-strength low-shrinkage, and reactive types. Polyester industrial yarn possesses advantages such as high breaking strength, high initial modulus, low elongation, and good impact resistance. It is widely used in industry, serving as the reinforcing material for rubber and plastic coated fabrics such as tire cords, cable sheaths, and conveyor belts. It can also be used to make ropes, automotive seat belts, conveyor belts, tarpaulins, coated fabrics, and geotextiles.

[0003] Polyester industrial yarn requires oiling during production and processing; currently, oiling devices are used for this purpose. However, the structural design of current oiling devices on the market is not reasonable enough, resulting in poor oiling continuity and uneven oiling of polyester industrial yarn, making them inconvenient to use. Moreover, these oiling devices have complex structures, are difficult to maintain, and have high operating costs. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a polyester filament guide assembly.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: A polyester filament guide assembly includes a take-up assembly and a spiral guide rail. The take-up assembly includes a mounting plate, on which two sets of guide rings are arranged at the front and rear. Each set of guide rings includes multiple guide rings. The spacing between the multiple guide rings in the front set is greater than the spacing between the multiple guide rings in the rear set. A tightening ring is also provided on the mounting plate behind the two sets of guide rings. The tightening ring is centered with the two sets of guide rings. A guide bend is provided on the mounting plate behind the tightening ring. The guide wire bend is bent at 90°. The inlet of the guide wire bend is located on the upper surface of the mounting plate, and the opening is aligned with the tightening ring. The outlet of the guide wire bend is located on the lower surface of the mounting plate and is vertically downward. The spiral guide rail is connected to the lower side of the mounting plate. The spiral guide rail is cylindrical and includes a spiral groove on its outer surface. Multiple oil grooves are provided on both the top of the spiral guide rail and the cylindrical surface. The oil grooves and the spiral groove intersect each other. An oil tank is provided on the lower surface of the mounting plate. An oil delivery pipe is provided at the bottom of the oil tank. The end of the oil delivery pipe is located in the oil groove at the top of the spiral guide rail.

[0006] Preferably, the edges of the spiral groove and the oil groove are smoothly transitioned by rounded corners.

[0007] Preferably, a rotating ring is provided at the outlet of the guide wire bend, and the outer surface of the rotating ring has a toothed structure. The rotating ring is rotatably connected to the outlet of the guide wire bend.

[0008] Preferably, the mounting plate is provided with a drive motor, and the drive shaft of the drive motor is fixedly connected to a gear, which meshes with a toothed structure.

[0009] The beneficial effects of this utility model are as follows: The spiral guide rail adopts a top-down spiral structure, which allows for rapid wire guiding and reduces the risk of wire breakage. Multiple oil grooves are provided on the surface of the spiral guide rail, interlacing with the spiral grooves used for wire guiding. When the wire bundle slides in the spiral grooves on the surface of the spiral guide rail, it will generate a certain rotation, which, combined with the oil grooves, allows for even oiling of the wire bundle, improving the uniformity of oil application. Furthermore, by providing a rotatable rotating ring, the rotation of the rotating ring can prevent friction on the same part of the rotating ring during the movement of the wire bundle, increasing the service life of the rotating ring.

[0013] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0014] Example: A polyester filament guide assembly, such as Figures 1-2As shown, the device includes a convergence assembly and a spiral guide rail 1. The convergence assembly includes a mounting plate 2, on which two sets of guide wire rings are arranged, one at the front and one at the back. Each set of guide wire rings includes multiple guide wire rings 3. The spacing between the multiple guide wire rings 3 in the front set is larger than the spacing between the multiple guide wire rings 3 in the rear set. A tightening ring 4 is also provided on the mounting plate 2 behind the two sets of guide wire rings. The tightening ring 4 is centered with the two sets of guide wire rings. A guide wire bend 5 is provided on the mounting plate 2 behind the tightening ring 4. The guide wire bend 5 is bent at 90°. The guide wire bend 5... The inlet is located on the upper surface of the mounting plate 2, and the inlet is aligned with the tightening ring 4. The outlet of the guide wire bend 5 is located on the lower surface of the mounting plate 2 and is vertically downward. The spiral guide rail 1 is connected to the lower side of the mounting plate 2. The spiral guide rail 1 is cylindrical and includes a spiral groove 6 on its outer surface. Multiple oil grooves 7 are provided on both the top and cylindrical surface of the spiral guide rail 1. The oil grooves 7 and the spiral groove 6 intersect each other. An oil tank 8 is provided on the lower surface of the mounting plate 2. An oil delivery pipe 9 is provided at the bottom of the oil tank 8. The end of the oil delivery pipe 9 is located in the oil groove 7 at the top of the spiral guide rail 1.

[0015] The edges of the spiral groove 6 and the oil groove 7 are smoothly transitioned by rounded corners; a rotating ring 10 is provided at the outlet of the guide wire bend 5, and a toothed structure 11 is provided on the outer surface of the rotating ring 10. The rotating ring 10 is rotatably connected to the outlet of the guide wire bend 5; a drive motor 12 is provided on the mounting plate 2, and a gear 13 is fixedly connected to the drive shaft of the drive motor 12. The gear 13 meshes with the toothed structure 11.

[0016] The principle of this invention: A single strand of filament is first gathered by two sets of guide rings, and then wound into the spiral groove 6 on the surface of the spiral guide rail 1 through the tightening tube and the guide bend tube 5. The spiral groove 6 can prevent the filament from breaking due to uneven force during the guiding process, and can further improve the speed of filament transmission. The oil in the oil tank 8 is transported to the oil groove 7 at the top of the spiral guide rail 1 through the oil supply pipe 9. The evenly distributed top oil groove 7 can guide the oil to the oil groove 7 on the circular surface, thereby wetting the filament. When the filament slides in the spiral groove 6 on the surface of the spiral guide rail 1, it will generate a certain rotation. With the help of the oil groove 7, the oil can be evenly wetting the filament, improving the uniformity of oil on the filament. In use, an oil receiving hopper is set at the bottom of the spiral guide rail 1.
