Description

Technical Field

[0001] This application belongs to the technical field of glass fiber production equipment, and particularly relates to a wear-resistant yarn guide that can be disassembled and replaced. Background Art

[0002] The wire arranging mechanism of a direct yarn drawing machine is the core component of the drawing machine. In particular, the grooved drum (cam) has a direct impact on the formation of the yarn bobbin. Since the glass fiber direct yarn is wound by a sliding shuttle reciprocating wire arrangement, the reciprocating motion of the sliding shuttle depends on the positive and negative double spiral grooves on the grooved drum. The positive and negative double spiral grooves push the sliding shuttle as the grooved drum rotates. Under the guidance of the guide plate, the sliding shuttle makes high-frequency reciprocations in the positive and negative double spiral grooves of the grooved drum to achieve linear reciprocating wire arrangement motion. However, this wire arrangement by the double spiral grooves of the grooved drum has two fatal defects: one is that the service life of the sliding shuttle is too short, the impact at both ends of the double spiral grooves of the grooved drum is large and it is easy to wear, the sliding shuttle needs to be replaced frequently during shutdown, and the speed cannot be increased, etc., which cannot meet the high wire speed drawing process; the second is the material and processing. Since the multi-strand drawing process is basically adopted for drawing now, the grooved drum also needs to meet the multi-strand drawing process, so the grooved drum will be longer. In order to increase its own rigidity and wear resistance, the grooved drum is usually processed and hardened as a whole, but it is easy to deform during the overall processing and the deformation is even greater after the hardening treatment, making it difficult to control. There are also contradictions in the material selection: since the double spiral grooves are suitable for milling cutter processing and the inner grooves are small, it is easy to wear or break the cutter, but the base material must have the characteristics of strong corrosion resistance, wear resistance and impact resistance. At present, in order to reduce the consumption of the sliding shuttle, the frequent shutdown for replacing the sliding shuttle and appropriately increase the running speed, the nylon sliding shuttle material is made by adding fibers or resin fibers to increase wear resistance and extend the life of the sliding shuttle. However, while increasing the wear resistance of the sliding shuttle, the hardness is also increased, resulting in excessive impact and too fast wear at both ends of the spiral grooves of the grooved drum.

[0003] The wire arranging plate, also known as the yarn guide piece, wire guide piece, wire guiding piece, etc., is an important component on the sliding shuttle. The reciprocating wire arrangement of the sliding shuttle is completed through the wire arranging port on the wire arranging plate. The above paragraph introduces one of the reasons why the sliding shuttle is easy to be damaged. Another reason for damage is that during the working process of the drawing machine, especially the high-speed drawing machine, since the wire arranging port is always in contact with the glass fiber yarn for wire arranging guidance, the wire arranging port becomes another easily damaged part. Utility Model Content

[0004] In view of this, this application provides a wear-resistant yarn guide that can be disassembled and replaced to solve all or part of the technical problems described in the background art part of this application.

[0005] The solution provided by this application to solve its technical problems is as follows:

[0006] A wear-resistant yarn guide that can be disassembled and replaced, including a yarn guide nozzle. The yarn guide nozzle has a U-shaped structure, and a snap groove and a locking portion are provided on the yarn guide nozzle.

[0007] Preferably, the buckle groove is arranged on the outer side surface of the yarn guide nozzle, and the locking head is arranged at the opening part of the yarn guide nozzle and extends to both sides.

[0008] Preferably, the detachable and replaceable wear-resistant yarn guide further comprises a wire arranging plate, on which a wire arranging opening is arranged, and a locking cooperation part is arranged at the opening part of the wire arranging opening; the yarn guide nozzle is arranged in the wire arranging opening, both sides of the wire arranging opening are arranged in the buckle groove, and a locking connection is formed between the locking part and the locking cooperation part. Further preferably, the locking part is a locking head, and the locking cooperation part is a locking groove or a locking hole.

[0009] Preferably, the wire arranging plate is further provided with assembly holes. The assembly holes are used for fixedly assembling the wire arranging plate to the shuttle.

[0010] Preferably, the wire arranging plate comprises a square part and an arc part, and the square part and the arc part are integrally formed. Further preferably, the assembly holes are arranged on the square part, and the wire arranging opening is arranged on the arc part. Further preferably, the arc part is of a semi-circular structure.

[0011] Preferably, a weight reduction structure is arranged on the wire arranging plate. The weight reduction structure can be in a honeycomb shape, a fan shape or an irregular shape.

[0012] Beneficial technical effects:

[0013] 1. In the present application, by arranging a yarn guide nozzle at the wire arranging opening of the shuttle wire arranging plate, when the yarn guide nozzle is severely worn and needs to be replaced, the yarn guide nozzle can be replaced through simple operations for equipment update, without having to replace the entire shuttle or the wire arranging plate. Thereby, the replacement time is reduced, and the equipment maintenance difficulty, the overhaul cost and the production cost are lowered.

[0014] 2. Since a separately formed yarn guide nozzle is adopted, more wear-resistant and impact-resistant materials such as titanium alloy, tungsten steel or non-metallic super wear-resistant materials can be selected for the yarn guide nozzle, further improving the service performance of the shuttle, without having to upgrade the materials of the entire shuttle or the wire arranging plate.

[0015] 3. In the prior art, generally, the wear time of the wire arranging opening is prolonged by thickening the wire arranging plate, but the thickened and heavier wire arranging plate has a large impulse, and when the shuttle performs wire arranging movement and commutation movement, the impact force on the matching components or parts on the grooved drum is also large, thus being easily damaged. In the present application, since a separately formed wear-resistant yarn guide nozzle is adopted, the wire arranging plate is allowed to be designed in a lightweight and flat shape. The lightweight wire arranging plate helps to reduce the overall running impulse of the shuttle, reduce the wear degree of the equipment, and at the same time can also reduce the equipment power consumption.

[0029] Please refer to Figures 1-8 , the wear-resistant yarn guide that can be disassembled and replaced includes a yarn guide nozzle 10. The yarn guide nozzle 10 has a U-shaped structure, and a snap groove 110 and a locking part 120 are provided on the yarn guide nozzle 10. The snap groove 110 is arranged on the outer side surface of the yarn guide nozzle 10, and the locking part 120 is arranged at the U-shaped opening part of the yarn guide nozzle 10 and extends to both sides.

[0030] The wire arranging board 20 includes a square part 240 and an arc part 250, and the square part 240 and the arc part 250 are integrally formed. The arc part 250 is a semi-circular structure. A wire arranging port 210 is provided on the arc part 250, and a locking cooperation part 220 is provided at the opening part of the wire arranging port 210. An assembly hole 230 is provided on the square part 240.

[0031] The yarn guide nozzle 10 is arranged in the wire arranging port 210, both sides of the wire arranging port 210 are arranged in the snap groove 110, and a connection is established between the locking part 120 and the locking cooperation part 220 through locking cooperation.

[0032] The locking part 120 is a locking head, and the locking mating part 220 is a locking groove. In a variant embodiment, the locking part 120 can be a locking groove and the locking mating part 220 can be a locking head.

[0033] To reduce the weight of the flexible printed circuit board 20, a weight reduction structure 260 is provided on the flexible printed circuit board 20. The weight reduction structure 260 can be honeycomb-shaped, fan-shaped or other shapes.

[0034] Principle and effect description:

[0035] The flexible printed circuit board 20 is fixedly assembled to the shuttles through the assembly holes 230. When the shuttles perform reciprocating wire laying, the glass fiber yarn and the U-shaped opening on the yarn guide nozzle 10 produce wire laying cooperation. When the yarn guide nozzle 10 is severely worn and needs to be repaired, the equipment can be maintained by simply replacing the yarn guide nozzle 10 without having to replace the entire shuttle or the flexible printed circuit board 20, which is beneficial to reducing the difficulty of equipment maintenance, as well as the overhaul cost and production cost.

[0036] At the same time, since the separately formed yarn guide nozzle 10 is adopted, more wear-resistant and impact-resistant materials such as titanium alloy, tungsten steel, silicon carbide and other expensive materials can be selected for the yarn guide nozzle 10, further improving the service performance of the shuttles without having to upgrade the materials of the entire shuttle or the flexible printed circuit board.

[0037] Moreover, since the separately formed yarn guide nozzle 10 is adopted, it also allows the flexible printed circuit board 20 to be designed to be lightweight and flat. The lightweight flexible printed circuit board 20 helps to reduce the overall running impulse of the shuttles, reduce the wear degree of the equipment, and at the same time can also reduce the power consumption of the equipment operation.

[0038] The technical solutions and technical effects of the present application have been elaborated in detail above in conjunction with the specification drawings and specific embodiments. It should be noted that those skilled in the art can also develop other embodiments on this basis; any simple deformation and equivalent replacement that do not deviate from the innovative concept of the present application are covered by the present application and belong to the protection scope of this patent.
