Description

Technical Field

[0001] This utility model relates to the field of twisting machine technology, and in particular to a multi-strand adjustable FDY polyester semi-dull retwisted black yarn twisting machine. Background Technology

[0002] FDY semi-dull retwisted black polyester yarn is widely used in the textile industry. It has advantages such as high strength, good abrasion resistance and color fastness. It is often used to make high-end clothing fabrics, functional textiles and industrial yarns. In the production process of FDY semi-dull retwisted black polyester yarn, the twisting machine is a crucial piece of equipment. It can twist multiple strands of monofilament into multifilament with a certain strength and twist to meet the needs of different products. For example, the adjustable twisting mechanism of a twisting machine disclosed in Publication No. CN223176300U discloses a technical solution including "a base, a first fixing block, a first motor, a first electro-hydraulic rod, a second electro-hydraulic rod, a second fixing block, and a second motor, which has the technical effect of adjusting the twisting length."

[0003] Although the design has technical advantages such as the ability to adjust the twist length, during the twisting process, the yarn drives the raw material bobbin to rotate on the first threaded post. The raw material bobbin is prone to rotating too fast under the pull of the yarn, resulting in excessive yarn release and slack, which in turn causes problems such as tangling and knotting, affecting the effect of FDY polyester semi-dull retwisted black yarn twisting. Utility Model Content

[0004] To overcome the technical defects of existing technologies, this utility model provides a multi-strand adjustable FDY polyester semi-dull retwisted black yarn twisting machine. The technical solution adopted by this utility model is: a multi-strand adjustable FDY polyester semi-dull retwisted black yarn twisting machine, including a base, a first support block fixedly connected to the upper surface of the base, and a first connecting column rotatably connected to a rotating hole opened in the top of the first support block. The surface of the first connecting column is fixedly fitted with a connecting block, and threaded rods are fixedly connected to the four sides of the connecting block. A raw material bobbin is fitted on the surface of each threaded rod. A long rod is inserted into a rectangular groove opened at the end of the threaded rod away from the connecting block. A square plate is inserted into a square groove opened at one end of the long rod. A spring is fixedly connected to one end of the square plate. The spring is used to provide resistance to the rotation of the raw material bobbin. An L-shaped rod is fixedly connected to the surface of the long rod. A threaded column is inserted into a threaded hole opened on the upper surface of the L-shaped rod. The threaded column is rotatable. Rotating the threaded column is used to change the resistance to the rotation of the raw material bobbin.

[0005] By adopting the above technical solution, through the cooperation of long rod, square plate, spring, L-shaped rod and threaded column, the resistance encountered when the raw material drum rotates can be flexibly adjusted, ensuring a stable wire release speed and avoiding wire loosening and tangling caused by the raw material drum rotating too fast.

[0006] Preferably, a hemispherical block is fixedly connected to the bottom end of the square plate, and an arc raceway is opened on one side of the raw material spool, with the hemispherical block inserted inside the arc raceway.

[0007] By adopting the above technical solution, the combination of the hemispherical block and the arc raceway provides resistance while reducing wear on the raw material drum, thus ensuring the smooth rotation of the raw material drum.

[0008] Preferably, the end of the spring away from the square plate is fixedly connected to a connecting plate, one end of the threaded column is rotatably connected to the connecting plate through a bearing, and one side of the connecting plate is in contact with the surface of the L-shaped rod.

[0009] By adopting the above technical solution, the connecting plate converts the rotational motion of the threaded column into a linear force on the spring. At the same time, the L-shaped rod guides the connecting plate, ensuring the stability of the spring's extension and contraction direction and guaranteeing the accuracy of resistance adjustment.

[0010] Preferably, a ruler rod is inserted into the longitudinal groove on the surface of the L-shaped rod, one end of the ruler rod is fixedly connected to the connecting plate, and the ruler rod and the L-shaped rod are fixedly connected.

[0011] By adopting the above technical solution, the scale rod moves synchronously with the connecting plate, which can intuitively reflect the positional changes of the connecting plate, and thus reflect the degree of spring extension and contraction, providing a clear reference for operators to adjust the rotational resistance of the raw material drum.

[0012] Preferably, the surface of the scale rod is inlaid with graduation lines.

[0013] By adopting the above technical solution, the scale line setting allows operators to accurately read the movement of the scale rod, thereby precisely controlling the compression or extension of the spring, realizing quantitative adjustment of the rotational resistance of the raw material drum, and ensuring that the resistance of multiple raw material drums remains consistent.

[0014] Preferably, the threaded rod has an inner slot that communicates with the rectangular groove, and an inner insert block is inserted into the inner slot, which is fixedly connected to the surface of the long rod.

[0015] By adopting the above technical solution, the cooperation between the inner insert block and the inner slot enhances the stability of the connection between the long rod and the threaded rod, preventing the long rod from shaking or falling off during equipment operation, and ensuring the stable operation of the resistance adjustment structure.

[0016] Preferably, a nut and an auxiliary ring are fitted onto the surface of the threaded rod. The nut and the threaded rod are threadedly connected, and the auxiliary ring and the threaded rod are slidably connected. The auxiliary ring is located between the nut and the long rod and is used to increase the height of the nut to prevent the L-shaped rod from affecting the efficiency of the nut's rotation.

[0017] By adopting the above technical solution, the auxiliary ring effectively solves the problem of the L-shaped rod hindering the rotation of the nut, enabling the nut to rotate quickly and smoothly to fix the raw material drum, thus improving the efficiency of raw material drum installation and replacement.

[0018] Preferably, a planar bearing is fitted onto the surface of the threaded rod, and the planar bearing is located between the raw material drum and the connecting block. The planar bearing is used to assist the rotation of the raw material drum.

[0019] By adopting the above technical solution, the flat bearing greatly reduces the friction coefficient between the raw material drum and the connecting block, reduces the resistance and wear during the rotation of the raw material drum, extends the service life of the raw material drum and the connecting block, and ensures the smooth rotation of the raw material drum.

[0020] The beneficial effects of this utility model are as follows: by setting a resistance adjustment structure composed of a long rod, a square plate, a spring, a threaded column, an L-shaped rod, etc., the resistance to the rotation of the raw material bobbin can be controlled. When the threaded column is rotated, the force of the spring on the square plate can be changed. Then, through the cooperation of the hemispherical block and the arc rolling track on one side of the raw material bobbin, the friction force on the raw material bobbin can be adjusted, so as to prevent the raw material bobbin from rotating too fast under the pull of the yarn, and to prevent the yarn from being released too much and loose, resulting in problems such as tangling and knotting. This significantly improves the effect and quality of FDY polyester semi-dull retwisted black yarn. The scale rod inserted in the longitudinal groove on the surface of the L-shaped rod is fixedly connected to the connecting plate at one end and has scale lines embedded on its surface. Operators can intuitively understand the degree of compression or tension of the spring through the scale, thereby accurately controlling the resistance of the raw material drum rotation. No experience is required for operation, which reduces the difficulty of operation and improves the accuracy of adjustment. At the same time, it can make the resistance of multiple raw material drums rotate in a consistent manner. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings: like Figures 1 to 8 As shown, this embodiment provides a multi-strand adjustable FDY polyester semi-dull retwisted black yarn twisting machine, including a base 1, a first support block 4 fixedly connected to the upper surface of the base 1, and a first connecting post 2 rotatably connected to a rotating hole on the top of the first support block 4. A connecting block 3 is fixedly sleeved on the surface of the first connecting post 2. Threaded rods 5 are fixedly connected to the four sides of the connecting block 3. A raw material bobbin 6 is sleeved on the surface of each threaded rod 5. A long rod 10 is inserted into a rectangular groove 9 at the end of the threaded rod 5 away from the connecting block 3. A square plate 17 is inserted into a square groove 18 at one end of the long rod 10. A spring 22 is fixedly connected to one end of the square plate 17. The spring 22 is used to provide resistance to the rotation of the raw material bobbin 6. An L-shaped rod 14 is fixedly connected to the surface of the long rod 10. A threaded post 13 is inserted into a threaded hole on the upper surface of the L-shaped rod 14. The threaded post 13 is rotatable, and rotating the threaded post 13 is used to change the resistance to the rotation of the raw material bobbin 6.

[0024] By adopting the above technical solution, through the cooperation of the long rod 10, square plate 17, spring 22, L-shaped rod 14 and threaded column 13, the resistance encountered by the raw material drum 6 when rotating can be flexibly adjusted to ensure the stable speed of the wire release and avoid the wire from loosening and tangling due to the raw material drum 6 rotating too fast.

[0025] Preferably, a hemispherical block 19 is fixedly connected to the bottom end of the square plate 17, and an arc raceway 20 is opened on one side of the raw material spool 6, with the hemispherical block 19 inserted inside the arc raceway 20.

[0026] By adopting the above technical solution, the cooperation between the hemispherical block 19 and the arc raceway 20 provides resistance while reducing wear on the raw material drum 6, thus ensuring the smooth rotation of the raw material drum 6.

[0027] Preferably, the end of the spring 22 away from the square plate 17 is fixedly connected to the connecting plate 15, and one end of the threaded column 13 is rotatably connected to the connecting plate 15 through a bearing. One side of the connecting plate 15 is in contact with the surface of the L-shaped rod 14.

[0028] By adopting the above technical solution, the connecting plate 15 converts the rotational motion of the threaded column 13 into a linear force on the spring 22. At the same time, the L-shaped rod 14 guides the connecting plate 15, ensuring the stability of the extension and retraction direction of the spring 22 and guaranteeing the accuracy of resistance adjustment.

[0029] Preferably, a ruler rod 16 is inserted into the longitudinal groove on the surface of the L-shaped rod 14, one end of the ruler rod 16 is fixedly connected to the connecting plate 15, and the ruler rod 16 and the L-shaped rod 14 are fixedly connected.

[0030] By adopting the above technical solution, the scale rod 16 moves synchronously with the connecting plate 15, which can intuitively reflect the positional change of the connecting plate 15, and thus reflect the degree of extension and contraction of the spring 22, providing a clear reference for operators to adjust the rotational resistance of the raw material drum 6.

[0031] Preferably, the surface of the scale rod 16 is inlaid with graduation lines.

[0032] By adopting the above technical solution, the scale line setting enables the operator to accurately read the movement of the scale rod 16, thereby precisely controlling the compression or extension of the spring 22, realizing quantitative adjustment of the rotational resistance of the raw material drum 6, and ensuring that the resistance of multiple raw material drums 6 remains consistent.

[0033] Preferably, the threaded rod 5 has an inner slot 12 that communicates with the rectangular groove 9, and an inner insert block 11 is inserted into the inner slot 12. The inner insert block 11 is fixedly connected to the surface of the long rod 10.

[0034] By adopting the above technical solution, the cooperation between the inner insert block 11 and the inner slot 12 enhances the stability of the connection between the long rod 10 and the threaded rod 5, prevents the long rod 10 from shaking or falling off during equipment operation, and ensures the stable operation of the resistance adjustment structure.

[0035] Preferably, a nut 7 and an auxiliary ring 8 are fitted onto the surface of the threaded rod 5. The nut 7 and the threaded rod 5 are threadedly connected, and the auxiliary ring 8 and the threaded rod 5 are slidably connected. The auxiliary ring 8 is located between the nut 7 and the long rod 10. The auxiliary ring 8 is used to raise the height of the nut 7 and prevent the L-shaped rod 14 from affecting the rotation efficiency of the nut 7.

[0036] By adopting the above technical solution, the auxiliary ring 8 effectively solves the problem of the L-shaped rod 14 hindering the rotation of the nut 7, enabling the nut 7 to rotate quickly and smoothly to fix the raw material drum 6, thereby improving the efficiency of the installation and replacement of the raw material drum 6.

[0037] Preferably, a planar bearing 21 is fitted on the surface of the threaded rod 5. The planar bearing 21 is located between the raw material drum 6 and the connecting block 3. The planar bearing 21 is used to assist the rotation of the raw material drum 6.

[0038] By adopting the above technical solution, the plane bearing 21 greatly reduces the friction coefficient between the raw material drum 6 and the connecting block 3, reduces the resistance and wear when the raw material drum 6 rotates, extends the service life of the raw material drum 6 and the connecting block 3, and ensures the smooth rotation of the raw material drum 6.

[0039] Working principle: The first connecting column 2 is rotatably connected to the rotating hole opened on the top of the first support block 4 and can rotate freely. The connecting block 3 is fixedly sleeved on the surface of the first connecting column 2 and rotates together with the first connecting column 2. Threaded rods 5 are fixedly connected to the four sides of the connecting block 3 respectively. The corresponding number of raw material bobbins 6 can be sleeved on the threaded rods 5 as needed for the required number of twists. When installing the raw material spool 6, first put the raw material spool 6 on the threaded rod 5. The plane bearing 21 is located between the raw material spool 6 and the connecting block 3, which can effectively assist the rotation of the raw material spool 6 and reduce the problem of damage caused by friction between the raw material spool 6 and the connecting block 3 when the raw material spool 6 rotates. Insert the long rod 10 into the rectangular groove 9 opened at the end of the threaded rod 5 away from the connecting block 3. At this time, the inner insert block 11 fixedly connected to the surface of the long rod 10 will be inserted into the inner slot 12 opened inside the threaded rod 5 and connected to the rectangular groove 9. Then, the auxiliary ring 8 and the nut 7 are put on in sequence. The nut 7 is threadedly connected to the threaded rod 5. By rotating the nut 7, the raw material spool 6, the plane bearing 21 and the auxiliary ring 8 can be fixed in a suitable position. The auxiliary ring 8 is located between the nut 7 and the long rod 10, which can raise the height of the nut 7 and avoid the L-shaped rod 14 affecting the rotation efficiency of the nut 7, so as to achieve a stable connection between the long rod 10 and the threaded rod 5. After the equipment is started, the first connecting column 2 begins to rotate, driving the connecting block 3 and the threaded rod 5 to rotate together, providing power for the twisting process. The filaments on the raw material spool 6 are released under tension. As the filaments are released, the raw material spool 6 rotates on the threaded rod 5. When it is necessary to adjust the resistance to rotation of the raw material drum 6, the threaded column 13 is rotated. The threaded column 13 moves within the threaded hole of the L-shaped rod 14, causing the connecting plate 15 to move. The connecting plate 15 then compresses or stretches the spring 22, changing the force exerted by the spring 22 on the square plate 17. A hemispherical block 19 is fixedly connected to the bottom end of the square plate 17. The hemispherical block 19 is inserted into the arc raceway 20 opened on one side of the raw material drum 6. The force of the spring 22 is transmitted to the hemispherical block 19 through the square plate 17, causing the hemispherical block 19 to generate a certain frictional force on the raw material drum 6, thereby providing friction for the raw material drum. 6. Rotation provides resistance. Meanwhile, a scale rod 16 is inserted into the longitudinal groove on the surface of the L-shaped rod 14. One end of the scale rod 16 is fixedly connected to the connecting plate 15. The surface of the scale rod 16 is inlaid with scale lines. The operator can intuitively understand the degree of compression or tension of the spring 22 through the scale of the scale rod 16, and accurately control the resistance of the rotation of the raw material spool 6. This prevents the raw material spool 6 from rotating too fast under the pull of the silk thread, and prevents the silk thread from being released too much and becoming loose, thereby avoiding problems such as tangling and knotting. At the same time, it can make the resistance of the rotation of multiple raw material spools 6 consistent. During the twisting process, the first connecting column 2 rotates continuously, driving the connecting block 3 and the threaded rod 5 to rotate, causing the filaments released from each raw material bobbin 6 to approach each other and twist together. As the twisting proceeds, the twisted filaments are continuously pulled, completing the entire twisting process of FDY polyester semi-dull retwisted black yarn. The twisting machine also includes, according to publication (announcement) number CN223176300U, an adjustable twisting mechanism for a twisting machine, comprising a first fixed block, a first motor, a first electro-hydraulic rod, a second electro-hydraulic rod, a second fixed block, and a first... The components include a two-motor, a twisting disc, a motor, a second connecting column, a driving gear, a driven gear, a second threaded column, an adjusting disc, an inner ring of the adjusting disc, a rotating disc, an inner ring of the rotating disc, a second support block, an L-shaped fixing frame, a sliding plate, a twisting wheel, a first U-shaped column, a first pressure roller, a second U-shaped column, a second pressure roller, a sliding block, a third U-shaped column, an auxiliary take-up roller, a third connecting column, and a take-up drum.
