Description

Technical Field

[0001] This utility model relates to the field of knitted fabric technology, specifically a rolling machine for knitted fabric processing. Background Technology

[0002] Knitted fabric is a type of fabric formed by bending yarns into loops and interlocking them using knitting needles. It is divided into warp-knitted and weft-knitted fabrics. Knitted fabrics are characterized by their soft texture, moisture absorption and breathability, and sweat-wicking and warmth retention. They generally possess excellent elasticity and extensibility. Compared to woven fabrics, they offer higher production volume and are suitable for small-batch production. The main functions of a knitted fabric winding machine include improving production efficiency, reducing labor costs, improving product quality, and increasing production process safety. Specifically, by automatically winding and unwinding textiles, a knitted fabric winding machine significantly improves production efficiency, reduces manual operation, and thus lowers the company's labor costs.

[0003] Existing rolling machines are only suitable for rolling knitted fabrics of specific sizes, which has a narrow range of applications. Furthermore, when rolling narrower knitted fabrics, deviations can easily occur, resulting in uneven rolling. In addition, existing rolling machines do not have the function of removing impurities and dust from the knitted fabric during the rolling process. If the surface of the knitted fabric is contaminated with dust or impurities during the rolling process, it will affect the overall rolling quality. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 1 and Figure 2As shown in this embodiment, a winding machine for knitted fabric processing includes a base 1. The base 1 is characterized by two symmetrically distributed mounting frames 2 on its upper surface, both sets of mounting frames 2 being slidably connected to the base 1. A first bidirectional lead screw 6 is provided inside the base 1. A winding rod 4 is provided between the two sets of mounting frames 2. Two symmetrically distributed limiting plates 5 are provided on the winding rod 4, and the two sets of limiting plates 5 are slidably connected to the winding rod 4. A second bidirectional lead screw 7 is provided on the winding rod 4. Two symmetrically distributed positioning frames 8 are provided on the base 1, and the two sets of positioning frames 8 are slidably connected to the base 1. The base 1 has two sets of symmetrically distributed bidirectional screws 9. Each of the two positioning frames 8 has a scraper 10. The two ends of the scraper 10 are rotatably connected to the positioning frame 8 via mounting shafts 11. The positioning frame 8 has two sets of symmetrically distributed fixing seats 15. Each fixing seat 15 contains a scraper block 17, which is correspondingly positioned to the scraper 10 and slidably connected to it. The motor on the base 1 drives the first bidirectional screw 6 to rotate. Under the limiting action of the base 1, the distance between the two sets of mounting frames 2 changes. By changing the distance between the two sets of mounting frames... The spacing between the frames 2 allows different types of winding rods 4 to be engaged between the two sets of mounting brackets 3 for winding different types of knitted fabrics. The two ends of the first bidirectional screw 6 pass through the base 1 and are rotatably connected to it via bearings. The two ends of the first bidirectional screw 6 also pass through the mounting frame 2 and are threadedly connected to it. Mounting brackets 3 are rotatably mounted on both sets of bases 1. The two ends of the winding rod 4 are movably engaged with the two sets of mounting brackets 3. The two ends of the second bidirectional screw 7 pass through the winding rod 4 and are rotatably connected to it via bearings. Two sets of limiting plates 5 pass through each end and are threadedly connected to the two sets of limiting plates 5 respectively. The second bidirectional lead screw 7 is driven to rotate by the motor inside the winding rod 4. Under the limiting action of the winding rod 4, the two sets of limiting plates 5 slide inward or outward synchronously. During the winding process of the winding rod 4 rotating with the card seat 3, the two sets of limiting plates 5 limit the two sides of the knitted fabric on the winding rod 4 to prevent the knitted fabric from shifting during the winding process, which would reduce the winding quality. In addition, the adjustment of the distance between the two sets of limiting plates 5 can also expand the range of knitted fabric that the winding rod 4 can wind.

[0023] like Figure 3 , Figure 4 and Figure 5As shown, the two ends of the two sets of bidirectional screws 9 pass through the base 1 and are rotatably connected to the base 1. The two ends of the two sets of bidirectional screws 9 pass through the two sets of positioning frames 8 and are threadedly connected to the two sets of positioning frames 8. By rotating the bidirectional screws 9 on the base 1, the distance between the two sets of positioning frames 8 is adjusted, thereby adjusting the gap between the upper and lower sets of scrapers 10. This allows the winding machine to be suitable for surface cleaning during the winding process of different types of knitted fabrics. A gear 12 is sleeved on the mounting shaft 11, a rack 13 is provided on the positioning frame 8, and a cylinder 14 is provided on the positioning frame 8. The rack 13 and the positioning frame 8. A sliding connection is established, with rack 13 connected to the output end of piston rod of cylinder 14. Rack 13 meshes with gear 12. After scraper 10 has been used for a period of time, cylinder 14 is activated to drive rack 13 to slide, which, in conjunction with gear 12, causes scraper 10 to rotate 120 degrees, completing the switching between scraper 10 and maintaining the cleaning effect of the winding machine on the surface of the knitted fabric. Both sets of fixed seats 15 are slidably connected to positioning frame 8. Positioning frame 8 is provided with two sets of threaded rods 16 corresponding to fixed seats 15. The two ends of threaded rods 16 pass through positioning frame 8 and are rotatably connected to positioning frame 8. The base 15 is threadedly connected to the fixed base 15. The converted scraper 10 faces upwards and corresponds to the fixed base 15 and the scraper block 17. During the rotation of the threaded rod 16, the fixed base 15 drives the scraper block 17 to slide on the positioning frame 8. The fixed base 15 is provided with a slide rod 18. The scraper block 17 is slidably sleeved with the slide rod 18 through a slider 19. A spring 20 is sleeved on the slide rod 18. The two ends of the spring 20 are fixedly connected to the slider 19 and the fixed base 15, respectively. The fixed base 15 is provided with a cam 21. The cam 21 is rotatably connected to the fixed base 15 through a rotating shaft. The cam 21 is in contact with the surface of the slider 19. The scraper block 17... As the fixed base 15 slides, the motor inside the fixed base 15 is activated to drive the cam 21 to rotate and intermittently push the slider 19. In conjunction with the slide rod 18 and the spring 20, the scraper block 17 slides back and forth on the fixed base 15 to clean the surface of the scraper 10. When the fixed base 15 moves the scraper 10 to both ends of the positioning frame 8 and disengages from the scraper 10, the scraper block 17 will remove the impurities adhering to the surface of the scraper 10 during the vibration process, thus maintaining the cleaning effect of the scraper block 17 on the scraper 10 and the cleaning effect of the scraper 10 on the knitted fabric.

[0024] This utility model provides a winding machine for knitted fabric processing. The specific working principle is as follows: The motor on the base 1 drives the first bidirectional lead screw 6 to rotate. Under the limiting action of the base 1, the distance between the two sets of mounting frames 2 changes. By changing the distance between the two sets of mounting frames 2, winding rods 4 of different models can be engaged between the two sets of mounting seats 3 for winding different models of knitted fabric. The motor inside the winding rod 4 drives the second bidirectional lead screw 7 to rotate. Under the limiting action of the winding rod 4, the two sets of limiting plates 5 move synchronously inward or outward. During the rolling process, as the winding rod 4 rotates with the card holder 3, two sets of limiting plates 5 limit the two sides of the knitted fabric on the winding rod 4, preventing the knitted fabric from shifting during rolling and reducing the rolling quality. Adjusting the distance between the two sets of limiting plates 5 also expands the range of knitted fabric that the winding rod 4 can roll. The distance between the two sets of positioning frames 8 is adjusted by rotating the bidirectional screw 9 on the base 1, thereby adjusting the gap between the upper and lower scraper plates 10. This allows the winding machine to be suitable for various applications. During the surface cleaning process of the same type of knitted fabric during the rolling process, after the scraper 10 has been used for a period of time, the cylinder 14 is activated to drive the rack 13 to slide, which, in conjunction with the gear 12, causes the scraper 10 to rotate 120 degrees, completing the conversion between scraper 10 and maintaining the cleaning effect of the rolling machine on the surface of the knitted fabric. After conversion, the scraper 10 faces upward and corresponds to the fixed seat 15 and the scraper block 17 respectively. During the rotation of the threaded rod 16, the fixed seat 15 drives the scraper block 17 to slide on the positioning frame 8. As the scraper block 17 slides with the fixed seat 15, the fixed seat is activated simultaneously. The motor inside 15 drives the cam 21 to rotate and intermittently pushes the slider 19. Together with the slide rod 18 and the spring 20, the scraper 17 slides back and forth on the fixed seat 15. While cleaning the surface of the scraper 10, when the fixed seat 15 moves the scraper 10 to both ends of the positioning frame 8 and disengages from the scraper 10, the scraper 17 will remove the impurities adhering to the surface of the scraper 10 during the vibration process, thus maintaining the cleaning effect of the scraper 17 on the scraper 10 and the cleaning effect of the scraper 10 on the knitted fabric.
