Description

Technical Field

[0001] This utility model relates to the field of sizing machines, specifically a yarn roll holder for a sizing machine. Background Technology

[0002] A sizing machine is a piece of equipment used in the textile industry. It is mainly used to sizing warp yarns to enhance their strength and abrasion resistance, ensuring that the yarns will not break during weaving. To ensure the smooth implementation of the sizing process, a yarn roll holder is used to provide stable support.

[0003] In the textile industry, sizing machines play a crucial role. By sizing yarn, they can significantly improve yarn strength and reduce surface friction, thereby enhancing fabric quality during subsequent weaving. The yarn cassette, as a key component of the sizing machine, undertakes the important tasks of supporting the yarn cassette and controlling yarn transport and winding. During the production process of the sizing machine, the yarn cassette needs to be compatible with yarn cassettes of different sizes. However, traditional yarn cassettes have some shortcomings. The installation spacing of traditional yarn cassettes is fixed, making it difficult to accommodate yarn cassettes of different widths. Changing the yarn cassette specifications requires manual disassembly and reassembly, which is time-consuming and labor-intensive, making it difficult to meet the adjustment needs of high-speed production.

[0022] According to one embodiment of the present invention, in conjunction with the appended drawings Figures 1-4 As shown.

[0023] A yarn roll holder for a sizing machine includes a square support 1. A support box 2 is fixedly connected to the bottom surface of the square support 1. A servo motor 8 is fixedly connected to the outer surface of the support box 2. A bidirectional lead screw 9 is fixedly connected to the output end of the servo motor 8. Two transmission screw plates 10 are threadedly connected to the outer surface of the bidirectional lead screw 9. Two sliding rods 11 are fixedly connected to the inner wall of the support box 2. Each sliding rod 11 is slidably connected to the transmission screw plate 10. A bottom square plate 12 is fixedly connected to the top of each of the two transmission screw plates 10. The top of each bottom square plate 12 passes through the support box 2 and the square support 1 and extends to the top of the square support 1. A side connecting box 13 is fixedly connected to the top of each bottom square plate 12. A set of long columns 15 are fixedly connected to the inner wall of each 13. A convex sliding seat 16 is slidably connected to the outer surface of each set of long columns 15. A connecting plate 17 is fixedly connected to one side of each convex sliding seat 16 through the side connecting box 13. Two fastening screws 21 are fixedly connected to the outer surface of each convex sliding seat 16. A fastening nut 22 is provided on the outer surface of each fastening screw 21. This constitutes the core adjustment structure of the yarn roll frame. The threads of the two-way screw 9 at the left and right ends are in opposite directions. The servo motor 8 drives the two-way screw 9 to realize automatic adjustment of the horizontal spacing. The long columns 15 and the convex sliding seats 16 cooperate to realize the vertical height adjustment to meet the installation requirements of yarn rolls of different sizes.

[0024] In this embodiment, the bottom surface of the square bracket 1 is fixedly connected with multiple mounting plates 5 with openings. The outer surface of each connecting plate 17 is provided with multiple connecting screws 18. The mounting plates 5 with openings provide standardized installation interfaces. The connecting screws 18 ensure that the yarn roll is tightly connected to the connecting plate 17 to prevent the yarn roll from falling off. The upper surface of the square bracket 1 has two sliding openings 14. Each bottom square plate 12 is slidably connected to the sliding opening 14. The sliding opening 14 provides a lateral movement channel for the bottom square plate 12, restricting its movement trajectory and ensuring that the two side connecting boxes 13 move synchronously and smoothly to avoid deviation. The upper surface of the square bracket 1 is fixedly connected with a support sliding column 6. The outer surface of the support sliding column 6 is slidably connected with two side sliding plates 7. The outer surface of each side sliding plate 7 is fixedly connected to the outer surface of the side connecting box 13. The support sliding column 6 and the side sliding plate 7 enhance the stability of the side connecting box 13, prevent the side connecting box 13 from shaking during lateral movement, and improve the reliability of the adjustment process.

[0025] In this embodiment, each side connecting box 13 has a side opening 19 on its outer surface that matches the convex sliding seat 16, and a side opening 20 on its outer surface that matches the fastening screw 21. The side opening 19 facilitates the adjustment of the height of the convex sliding seat 16 extending out of the side connecting box 13, while the side opening 20 facilitates the installation and locking of the fastening screw 21, improving operational convenience. A connecting collar 23 is rotatably connected to the outer surface of the bidirectional screw 9. The bottom surface of the connecting collar 23 is fixedly connected to the inner bottom wall of the support box 2, and the connecting collar 23 supports the bidirectional screw 9. The middle section of the lead screw 9 reduces the cantilever length, decreases bending deformation during transmission, and ensures the transmission accuracy and service life of the bidirectional lead screw 9. A scale 4 is fixedly connected to the upper surface of the square bracket 1, and an operation button 3 is fixedly installed on the outer surface of the square bracket 1. The operation button 3 is electrically connected to the servo motor 8 through a wire. The scale 4 provides a quantitative reference for the spacing, allowing operators to directly read and adjust the spacing according to the yarn roll width, reducing visual error and improving adjustment accuracy. The operation button 3 controls the start and stop of the servo motor 8, simplifying the adjustment process and reducing manual labor intensity.

[0026] Working principle: In use, the servo motor 8 is started by operating button 3 according to the size of the yarn roll to be supported, so that it drives the bidirectional lead screw 9 to rotate. When the bidirectional lead screw 9 rotates, it can drive the two transmission screw plates 10 to slide along the slide bar 11. The two transmission screw plates 10 move closer to each other or further apart. It can move the side connecting box 13 through the bottom square plate 12. After the two side connecting boxes 13 are adjusted to a suitable lateral distance, the convex sliding seat 16 can slide up and down along the long column 15. After the convex sliding seat 16 and the connecting plate 17 are adjusted to a suitable longitudinal height, the adjusted longitudinal height is fixed by multiple fastening nuts 22 and fastening screws 21. Then, the yarn roll is installed on the connecting plate 17 by connecting screws 18.

[0027] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
