Description

Technical Field

[0001] This invention relates to the field of spinning equipment technology, and more particularly to a bundling device for spinning. Background Technology

[0002] Spinning and bundling is an important process in the textile industry, involving combining multiple fine fibers or single yarns into a thicker yarn. This process not only enhances the strength and uniformity of the yarn but also improves its appearance, making it more suitable for subsequent weaving or other processing steps.

[0003] In existing technologies, yarn doubling and twisting typically requires multiple pieces of equipment such as doubling machines and spinning machines. Furthermore, during doubling and twisting, two or more yarns are often fed into the spindle at different angles, resulting in significant resistance to the yarn, uneven yarn feeding, and easily uneven tension between the yarns on the left and right sides. To address the inability to adjust the tension, existing devices disclose a spinning bundle device with tension adjustment function. This device applies pressure to the yarn via a tension adjustment wheel to adjust the yarn tension during the bundle process. However, this tension adjustment inevitably causes changes in the yarn spacing.

[0004] The spacing between yarns directly affects the control of fibers during the drafting process, thus impacting yarn evenness and bundling effect. If the spacing is too large, the fibers are prone to becoming uncontrollable during drafting, leading to uneven yarn; if the spacing is too small, the fibers are prone to entanglement, also affecting yarn evenness. Therefore, we propose a bundling device for spinning. Summary of the Invention

[0005] Based on the technical problems existing in the background technology, the present invention proposes a yarn bundling device, which has the characteristics of adjusting the yarn tension during the bundling process and keeping the yarn spacing constant to ensure yarn evenness. This solves the problem that the existing bundling device inevitably causes changes in the yarn spacing when adjusting the yarn tension during the bundling process, thus affecting the yarn evenness and bundling effect.

[0006] The present invention provides the following technical solution: a yarn bundling device, comprising a housing, an inlet ring for yarn to pass through, and a bundling mechanism; the inlet ring is installed on one side of the housing, and an outlet hole is provided on the other side of the housing; A fixing plate is installed inside the inlet ring, and a clustering mechanism is provided inside the outer shell. A telescopic rod is fixed on the fixing plate, and the telescopic end of the telescopic rod is connected to the clustering mechanism. The bundling mechanism has several rollers inside, and each roller is equipped with a pressure sensor at the connection point with the bundling mechanism. The yarn passes through the inlet ring, and after being bundled by the rollers of the bundling mechanism, it passes through the outlet hole. The diameter of the inlet ring is larger than the diameter of the bundling mechanism. The telescopic rod is used to adjust the distance between the bundling mechanism and the infeed ring, thereby adjusting the yarn traction force by pressing and releasing the yarn through the rollers while keeping the yarn outlet spacing constant. The pressure sensor is used to detect changes in the traction force of the yarn.

[0007] Preferably, the infeed ring includes an outer ring and an inner ring, which are fixed together by a connecting rod, and a wire sleeve for the yarn to pass through is provided between the outer ring and the inner ring.

[0008] Preferably, the clustering mechanism is equipped with a plurality of telescopic rods II corresponding to the rollers, and the rollers are installed at the telescopic ends of the telescopic rods II; The second telescopic rod is fixed to the bundling mechanism by a support rod, and the telescopic direction of the second telescopic rod is parallel to the yarn exit path.

[0009] Preferably, the telescopic end of the telescopic rod 2 is provided with a rotating shaft, the roller is sleeved on the rotating shaft, and a pressure sensor for detecting the pressure of the roller is provided on the rotating shaft.

[0010] Preferably, the support rod is connected to an annular oil groove via a bracket. The oil groove contains a sponge and spinning oil. The oil groove is also sleeved on the telescopic ends of several telescopic rods. The telescopic rods are used to bring the roller into contact with the spinning oil in the oil groove after retraction to achieve oiling.

[0011] Preferably, the support rod is connected to an annular oil trough via a telescopic rod three. The oil trough contains a sponge and spinning oil. The oil trough is located at the bottom of several rollers. The telescopic rod three is used to drive the oil trough to rise and contact the rollers to achieve oiling.

[0012] Preferably, the support rod is connected to an oil trough by several telescopic rods. The oil troughs are correspondingly set at the bottom of several rollers. The oil troughs contain sponges and spinning oil. Each telescopic rod is used to drive the corresponding oil trough to contact the corresponding roller, so as to achieve oiling of one or more rollers.

[0013] Preferably, the oil tank is connected to the oil reservoir via an oil injection pipe, and the oil reservoir is used to supply oil to the oil tank via the oil injection pipe.

[0014] Preferably, the clustering mechanism has a built-in infrared thermometer, the probe of which is aligned with the roller to detect temperature changes in the roller.

[0015] Preferably, the wire sleeve is provided with a limiting member, the outer ring is provided with a plurality of limiting grooves one that match the limiting member, and the inner ring is provided with a plurality of limiting grooves two that match the limiting member. The wire sleeve is fixed at any position between the outer ring and the inner ring by the limiting member cooperating with the limiting grooves one and two. The outer ring is provided with a scale line one for positioning the wire sleeve, and the inner ring is provided with a scale line two for positioning the wire sleeve.

[0016] This invention provides a yarn bundling device. A telescopic rod drives the bundling mechanism to move parallel to the yarn outlet direction. This not only allows for yarn tension adjustment by pressing the yarn with rollers, but also, because the rollers move parallel to the yarn outlet direction, the tension adjustment process only affects the yarn direction between the inlet ring and the bundling mechanism, without affecting the yarn spacing, the inlet position and spacing of the inlet ring, or the yarn outlet position and spacing of the outlet hole. This solves the problem in existing bundling devices where adjusting yarn tension during the bundling process inevitably leads to changes in yarn spacing, thus affecting yarn evenness and bundling effect.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1 As shown, the present invention provides a technical solution: a yarn bundling device, including a housing 1, an inlet ring for yarn 10 to pass through, and a bundling mechanism 8; the inlet ring is installed on one side of the housing 1, and an outlet hole 9 is provided on the other side of the housing 1; the inlet ring is used for the yarn 10 to enter the bundling device, and the outlet hole 9 is the yarn outlet after bundling.

[0030] The fixing plate 6 is installed inside the inlet ring. The purpose of the fixing plate 6 inside the inlet ring is to install the bundling mechanism 8. The bundling mechanism 8 is located inside the outer shell 1. The telescopic rod 7 is installed on the fixing plate 6. Then, the telescopic end of the telescopic rod 7 is connected to the bundling mechanism 8, which can fix the bundling mechanism 8. The extension and retraction of the telescopic rod 7 can drive the bundling mechanism 8 to rise and fall, thereby adjusting the pressure of the yarn 10.

[0031] like Figure 2 As shown, the bundling mechanism 8 has several rollers 81 arranged in a ring, corresponding one-to-one with the wire sleeves 4 in the inlet ring. A yarn 10 passes through each roller 81, and a pressure sensor 82 is installed at the connection between each roller 81 and the bundling mechanism 8. The yarn 10 passes through the inlet ring, and after being bundled by the rollers 81 of the bundling mechanism 8, it passes through the outlet hole 9. The diameter of the inlet ring is larger than the diameter of the bundling mechanism 8, which facilitates the inlet and bundling of the yarn.

[0032] Telescopic rod 7 is used to adjust the distance between the bundling mechanism 8 and the inlet ring. Thus, while maintaining a constant yarn exit spacing, the rollers 81 press and release the yarn 10, adjusting the traction force of the yarn 10. During the extension and retraction of telescopic rod 7, the distance between the rollers 81 remains constant, ensuring that the spacing of the bundled yarn 10 output from the bundling mechanism 8 and the outlet hole 9 remains unchanged. Then, during the retraction of telescopic rod 7, the bundling mechanism 8 and the rollers 81 simultaneously press the yarn 10 upwards, increasing the tension of the bundled yarn 10 and achieving tension adjustment. This adjustment also simultaneously regulates the tension of the yarn 10 on all rollers 81. When it is necessary to reduce the tension of the yarn 10, the extension of telescopic rod 7 reduces the pressure on the yarn 10 from the rollers 81, thereby reducing the bundle tension of the yarn 10. The pressure sensor 82 on the rollers 81 detects changes in the traction force of the yarn 10, enabling precise control of the yarn tension.

[0033] like Figure 3 As shown, the infeed ring includes an outer ring 2 and an inner ring 3. The outer ring 2 and the inner ring 3 are fixed together by a connecting rod 5. Multiple connecting rods 5 are provided and are evenly distributed at intervals between the yarns 10. On the one hand, this ensures the stability between the inner ring 3 and the outer ring 2, and on the other hand, it avoids blocking the yarn 10 from entering.

[0034] Furthermore, a guide sleeve 4 is provided between the outer ring 2 and the inner ring 3 for the yarn 10 to pass through. Several guide sleeves 4 are provided, which can be arranged in a ring at equal intervals as needed.

[0035] The telescopic rod 7 is connected to the bundling mechanism 8 via the fixed rod 71, and the fixed rod 71 is located between two adjacent rollers 81 to avoid the path of the yarn 10. There are also several rollers 81, the number of which is the same as the number of wire sleeves 4, and they correspond one-to-one, so that each yarn 10 passing through the wire sleeve 4 can enter the rollers 81 for bundling.

[0036] like Figure 4 As shown, the bundling mechanism 8 has several telescopic rods 83 corresponding to rollers 81 installed inside. Rollers 81 are mounted on the telescopic ends of the telescopic rods 83. The telescopic rods 83 are fixed to the bundling mechanism 8 via support rods 84, and the telescopic direction of the telescopic rods 83 is parallel to the yarn exit path of the yarn 10. The telescopic rods 83 can drive rollers 81 to move along the yarn exit direction of the yarn 10. When the yarn moves, pressure can be applied to one yarn 10 individually to adjust its tension. Because rollers 81 move along the yarn exit direction of the yarn 10, the tension of the yarn 10 passing through rollers 81 increases, but the distance between the yarn and other yarns 10 does not change when it exits. Figure 4As shown, the left roller 81 is lower than the right roller 81, and the tension of the yarn 10 on the right roller 81 is greater than that on the left roller 81. However, the exit positions and spacing of the yarns on both rollers remain unchanged, and they are parallel to each other. This allows for tension adjustment of any one or more yarns 10 without affecting their exit positions or spacing, thus avoiding uneven yarn count caused by changes in the yarn spacing.

[0037] like Figure 4 As shown, the telescopic end of the telescopic rod 83 is equipped with a rotating shaft, and the roller 81 is sleeved on the rotating shaft. A pressure sensor 82 for detecting the pressure of the roller 81 is also installed on the rotating shaft. Since the direction of force inevitably changes during the up-and-down movement of the roller 81, by placing the pressure sensor 82 on the rotating shaft, the pressure change transmitted from the roller 81 to the telescopic rod 83 can be detected more accurately, thereby determining the tension of the yarn 10.

[0038] like Figure 5 and 6 As shown, a circular oil groove 85 is fixed to the support rod 84 by a bracket. The oil groove 85 contains a sponge and spinning oil. When the friction is too strong, the yarn experiences excessive resistance during drafting, causing it to be unable to change speed and run normally, and also resulting in thick and thin spots. The amount of oil applied has a significant impact on the fiber friction and yarn bundle cohesion. When poor bundling occurs, the oiling effect of the spinning oil needs to be checked first. By setting up the oil groove 85, oiling of the yarn 10 can be achieved.

[0039] The oil trough 85 is simultaneously fitted onto the telescopic ends of several telescopic rods 83. After retraction, any one of the telescopic rods 83 can lower the roller 81 to contact the spinning oil in the oil trough 85, thus achieving oiling. The oil trough 85 is connected to the oil tank 88 via an oil injection pipe 87. The oil injection pipe 87 is made of a small-diameter thin tube or fiber material, utilizing capillary action to guide the oil from the oil tank 88 into the oil trough 85. The sponge in the oil trough 85 effectively transfers the oil to the roller 81, thereby oiling the yarn 10. Oiling can be applied to a single yarn 10 or multiple yarns 10 simultaneously.

[0040] like Figure 7 As shown, a circular oil trough 85 is connected to the support rod 84 via a telescopic rod 86. The oil trough 85 contains a sponge and spinning oil. The oil trough 85 is located at the bottom of several rollers 81. The oil trough 85 is connected to the oil tank 88 via an oil injection pipe 87. The oil injection pipe 87 is made of a thin tube or fiber material with a small diameter. It uses capillary action to guide the oil in the oil tank 88 into the oil trough 85.

[0041] Telescopic rod 86 drives oil tank 85 to rise and contact roller 81. The sponge in oil tank 85 effectively transfers oil to roller 81, thus oiling the yarn 10. By setting telescopic rod 86 to independently drive the entire oil tank 85 up and down, all yarns 10 can be oiled simultaneously. This avoids the need to adjust telescopic rod 83, as adjusting telescopic rod 83 would affect the tension of the yarn 10. Preventing the tension of the yarn 10 from being affected during oiling ensures that the yarn 10 maintains continuous tension while oiling, achieving automated oiling of the yarn 10 without affecting processing efficiency and quality.

[0042] like Figure 8 As shown, an oil trough 85 is connected to a support rod 84 via several telescopic rods 86. These oil troughs 85 are correspondingly positioned at the bottom of several rollers 81. Each oil trough 85 contains a sponge and spinning oil. Each telescopic rod 86 drives the corresponding oil trough 85 to contact the corresponding roller 81, thus oiling one or more rollers 81. The oil trough 85 is connected to an oil tank 88 via an oil injection pipe 87. The oil injection pipe 87 is made of a small-diameter thin tube or fiber material, utilizing capillary action to guide the oil from the oil tank 88 into the oil trough 85.

[0043] By setting up several telescopic rods 86, each telescopic rod 86 is equipped with a separate oil trough 85, so that the oil trough 85 can be adjusted individually by the telescopic rods 86, and thus, when the telescopic rod 83 is stationary, that is, the tension of the yarn 10 remains unchanged, a single yarn 10 can be oiled.

[0044] like Figure 6 , 7 As shown in Figure 8, the bundling mechanism 8 has a built-in infrared thermometer 89. The probe of the infrared thermometer 89 is aimed at the roller 81 to detect the temperature change of the roller 81. When the friction of the yarn 10 is abnormal, it will cause the temperature of the roller 81 to rise. By monitoring the temperature change of the roller 81, the friction of the yarn 10 can be indirectly detected. When the infrared thermometer 89 detects an abnormal temperature of a certain roller 81, it will apply oil to it through the oil tank 85 to ensure that the friction of the yarn 10 is normal during the bundling process.

[0045] like Figure 9 and 10As shown, the wire sleeve 4 is provided with a limiting member 41, the outer ring 2 is provided with several limiting grooves 21 that match the limiting member 41, and the inner ring 3 is provided with several limiting grooves 31 that match the limiting member 41. The wire sleeve 4 is fixed at any position between the outer ring 2 and the inner ring 3 by the cooperation of the limiting member 41 with the limiting grooves 21 and 31. By providing the limiting member 41 and the limiting grooves, the installation and removal of the wire sleeve 4 are convenient, allowing the user to set several fiber sleeves at equal intervals as needed. Then, according to the number of wire sleeves 4, the matching bundling mechanism 8 is replaced.

[0046] The outer ring 2 has a scale line 22 for positioning the wire sleeve 4, and the inner ring 3 has a scale line 32 for positioning the wire sleeve 4. The scale lines make it easy for staff to confirm the distance between two adjacent wire sleeves 4, thus facilitating the replacement and installation of the wire sleeve 4.

[0047] This invention enables tension adjustment of the yarn 10 during the spinning and bundling process, while ensuring that the yarn spacing is not affected during adjustment. A reasonable spacing allows the fibers to maintain good parallelism and straightness during drafting, thus achieving a better bundling effect. This avoids the problem in existing technologies where unreasonable spacing due to yarn tension adjustment affects the fiber bundling effect, leading to a decrease in yarn strength and uniformity.

[0048] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
