Three-roller type yarn guide roller device of warping table

Abstract

The three-roller type yarn guide roller device comprises a yarn guide roller bottom plate (4), a left side plate (5) and a right side plate (5) are arranged on the yarn guide roller bottom plate (4), a front yarn guide roller assembly (6) and a rear yarn guide roller assembly (7) are arranged between the left side plate (5) and the right side plate (5), and a middle yarn guide roller assembly (8) is arranged between the front yarn guide roller assembly (6) and the rear yarn guide roller assembly (7). According to the three-roller type yarn guide roller device of the warping table, the three yarn guide rollers are arranged on the same horizontal plane in a front-middle-rear mode, yarn is wound to the upper portion of the middle yarn guide roller from the bottom of the front yarn guide roller and then wound to the large roller through the bottom of the rear yarn guide roller to be warped, the yarn is warped under the holding of the three yarn guide rollers in the S-shaped winding mode, and therefore the yarn quality is improved. Yarn tension is more uniform and stable, yarn diffusion can be effectively reduced, and strip splicing is more accurate and neat.

Description

technical field [0001] The invention relates to a three-roller type yarn guide roller device for a warping table, which belongs to the technical field of textile machinery. Background technique [0002] At present, the yarn guide roller device of the warping table of the slit warping machine mostly adopts a single yarn guide roller structure, such as figure 1 As shown in the figure, the yarn 1 is wound on the large drum 3 after passing through the yarn guide roller device 2. When this warping process is used for relatively smooth yarns such as chemical fiber filaments, the yarn is prone to slippage during the climbing process. The spread of the yarn leads to the inaccuracy of the splicing and the beading, which makes it difficult for the subsequent reversal of the shaft. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a three-roller type yarn guide roller device for the warping table in view of the above-mentione...

[0002] The current guide roller device of the warping table of the section warping machine mostly adopts a single guide roller structure, such as figure 1 As shown, the yarn 1 is wound on the large drum 3 after passing through the guide roller device 2. When this warping process is used to make relatively smooth yarns such as chemical fiber filaments, the yarn is prone to slipping during the climbing process. Yarn spreading leads to inaccurate splicing and beading, which makes it difficult for the subsequent shaft reversing
