Description

Technical Field

[0001] The utility model relates to the technical field of yarn flattening machines, in particular to a yarn flattening device for a sizing machine. Background Art

[0002] Polyester-cotton cloth not only maintains the characteristics of high strength and good elastic recovery of polyester fiber, but also has the characteristics of strong hygroscopicity of cotton fiber. It is easy to dye, does not need ironing and dries quickly after washing. An important process in the production of polyester-cotton cloth is warp sizing, which applies sizing to the warp yarn to improve its weavability. Weavability refers to the ability of the warp yarn to withstand repeated friction, stretching, bending, etc. of the warp stop piece, heald, reed, etc. on the loom without causing a lot of pilling or even breaking. After sizing is completed, the yarn is flattened using a yarn flattening mechanism, which is mainly squeezed by the rotating rollers of the yarn flattening mechanism.

[0003] However, the common yarn-leveling mechanism of a sizing machine cannot adjust the gap between the two yarn-leveling rollers, resulting in the mechanism being only usable for yarns with a fixed diameter, limiting its scope of use. Therefore, to address the problem that the yarn-leveling mechanism of a sizing machine cannot adjust the gap between the two yarn-leveling rollers, resulting in the mechanism being only usable for yarns with a fixed diameter, we propose a yarn-leveling device for a sizing machine.

[0023] The adjusting mechanism includes an adjusting groove 7, an adjusting screw 8, a connecting block 9 and a threaded groove 10. An adjusting groove 7 is provided on the wall surface of the adjusting block 5 close to the extrusion roller 3. The inner bottom surface of the adjusting groove 7 is connected to the adjusting screw 8 through a bearing. The top of the adjusting screw 8 extends upward through the interior of the adjusting block 5 to the top of the adjusting block 5. A connecting block 9 is provided inside the adjusting groove 7. A threaded groove 10 is provided on the connecting block 9 at a position corresponding to the adjusting screw 8. The connecting block 9 is threadedly connected to the adjusting screw 8 through the threaded groove 10. The end of the connecting block 9 away from the adjusting block 5 is fixedly connected to the side wall surface adjacent to the corresponding linkage rod 6.

[0024] A limiting groove 11 is defined inside the adjusting groove 7 , and one end of the connecting block 9 close to the limiting groove 11 is movably engaged in the limiting groove 11 .

[0025] Since the connecting block 9 is threadedly connected to the adjusting screw rod 8 through the threaded groove 10, and one end of the connecting block 9 is movably clamped inside the limiting groove 11, it can limit the connecting block 9. Therefore, when in use, by rotating the adjusting screw rod 8 clockwise or counterclockwise, the connecting block 9 can be driven to move upward or downward inside the adjusting groove 7. The connecting block 9 drives the linkage rod 6 to move up and down, which can achieve the effect of adjusting the position of the extrusion roller 3 up and down, so that it can be used for yarns of multiple diameters, solving the problem that the existing sizing machine flat yarn mechanism can only be used for yarns of fixed diameter.

[0026] The dust removal mechanism includes a connecting rod 12, a scraper 13, a connecting column 14 and a connecting groove 15. The two linkage rods 6 are fixedly connected to the position of the extrusion roller 3 on the side wall surface away from the driving roller 2. A scraper 13 is arranged between the two connecting rods 12. Both ends of the scraper 13 are fixedly connected to the connecting column 14. The linkage rod 6 is provided with a connecting groove 15 at the position corresponding to the connecting column 14 on the scraper 13.

The free end of the spring 17 is fixedly connected to the side wall connected to the top block 18, and the spring 17 is in a tensioned state.

[0028] The blade edge of the scraper 13 contacts the outer wall surface of the squeezing roller 3. When in use, the spring 17 will apply an upward thrust to the top block 18, and the top block 18 will drive the scraper 13 to always contact the outer wall surface of the squeezing roller 3 through the connecting column 14.

[0029] Working principle:

[0030] When in use, by rotating the adjusting screw rod 8 clockwise or counterclockwise, the connecting block 9 can be driven to move upward or downward in the adjusting groove 7. The connecting block 9 drives the linkage rod 6 to move up and down, which can achieve the effect of adjusting the position of the squeezing roller 3 up and down, so that it can be used for yarns of multiple diameters, solving the problem that the existing sizing machine flat yarn mechanism can only be used for yarns of fixed diameter.

[0031] When in use, the scraper 13 can scrape off dust and impurities on the outer wall surface of the squeezing roller 3, and since the movable groove 16 is internally movably clamped with a top block 18, and the top block 18 is connected to the free end of the spring 17 inside the movable groove 16, and the spring 17 will apply an extrusion force to the scraper 13 through the top block 18, so that the scraper 13 will fit tightly with the outer wall surface of the squeezing roller 3 under the action of the elastic force of the spring 17, thereby further improving the scraper 13 The cleaning effect of the dust and impurities on the squeezing roller 3 is further improved.
