Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a novel FDY main network device with a stable structure. Background Art

[0002] FDY is a synthetic fiber filament made by spinning and stretching. Since the fiber has been fully stretched, it can be directly used for textile processing. FDY fabric feels smooth and soft, and is often used to weave imitation silk fabric. The FDY main networker is one of the important parts of the spinning machine for producing FDY fabric. Its function is to network the tow to increase the strength of the yarn.

[0003] However, most of the existing main network devices are made of metal materials, which will generate great friction when the fibers pass through, which will not only cause great losses and shorten the life of the network device, but will also affect the quality of the fibers. In addition, due to the stability of the wire feeding and collecting device and the tension of the fibers themselves, the fibers will inevitably shake to a certain extent. The shaking amplitude will change the path of the fibers entering the network device, and at some special angles it will even increase the contact with the edges and corners of the inner hole of the network device, causing damage to the fibers. Utility Model Content

[0027] The guide 8 is mounted on the base 1 via a fixing structure.

[0028] See also Figure 1-Figure 3 As shown, the elastic guide assembly includes an outer guide ring 13 arranged above the seat body 1, the central axis of the outer guide ring 13 is opposite to the inner guide ring 12, a sliding rod 14 is connected to the lower part of the outer guide ring 13, and a plurality of anti-rotation convex grooves 15 are evenly arranged on the outer side of the sliding rod 14, and the seat body 1 is provided with a plurality of anti-rotation convex grooves 15 connected to the sliding rod 14 and the anti-rotation convex grooves.

Several fixing holes 1 3 are symmetrically opened in the two fixing plates 2, and several fixing holes 2 10 corresponding to the fixing holes 1 3 are opened in the guide 8. Fixing pins 4 are movably inserted in the fixing holes 1 3 and the fixing holes 2 10, and a through hole is opened at one end of the fixing pin 4. A fixing screw 6 is movably inserted in the through hole. A nut seat 5 is provided on the base body 1 directly below the through hole, and the fixing screw 6 is connected to the nut seat 5 through a thread.

[0031] See also Figure 1-Figure 6 As shown, a plurality of vertical positioning posts 7 are fixed on the seat body 1 below the guide 8, a plurality of positioning grooves 11 matching the vertical positioning posts 7 are provided in the guide 8, a trumpet-shaped guide groove 18 is provided at the mouth of the positioning groove 11, and the vertical positioning posts 7 are movably inserted in the positioning groove 11.

[0033] See also Figure 1-Figure 5 As shown, both side openings of the wire guide groove 9 are provided with arc chamfers.

[0034] The principle and use process of this utility model:

[0035] After the main network device is installed, the fiber filament is passed through the outer guide ring 13, the inner guide ring 12, and the guide groove 9 in sequence, and then passed through the inner guide ring 12 and the outer guide ring 13 on the other side, and the operation can be started after connecting to the other equipment;

[0036] During the operation, due to the influence of tension and the external environment, the fiber filaments shake and press onto the inner wall of one side of the outer guide ring 13, generating a force on the outer guide ring 13, and the two springs 17 can be passively compressed or extended, thereby absorbing the force and generating a reaction force, thereby slowing down the shaking speed of the fiber line and reducing the friction between the highly moving fiber filaments and the outer guide ring 13. Then the inner guide ring 12 guides and straightens the fiber filaments, thereby ensuring that the direction of the fiber filaments is accurate when entering the wire guide groove 9. The chamfers at both ends of the wire guide groove 9 can prevent the fiber filaments from being scratched, and the smooth ceramic guide 8 and guide ring can greatly reduce the friction generated when the fiber passes through, thereby reducing losses and improving product quality.

[0037] When the guide 8 or the seat body 1 needs to be replaced after using it for a period of time, the fixing screw 6 is removed through the thread, and then the fixing pin 4 is pulled out from the other end, and the guide 8 can be lifted up, and the guide 8 or the seat body 1 can be replaced, and then the newly matched guide 8 and the seat body 1 are aligned so that the vertical positioning column 7 is aligned with the guide groove 18, and the guide 8 can be lowered. After the vertical positioning column 7 enters the guide groove 18, it can automatically enter the positioning groove 11 along the inner wall of the guide groove 18, and then the fixing pin 4 and the fixing screw 6 are fixed in sequence to complete the installation, which is simple and quick.
