Description

Technical Field

[0001] This utility model belongs to the field of spinning machine technology, specifically relating to a feeding positioning mechanism and a fine spinning machine. Background Technology

[0002] The ring spinning frame is a crucial piece of equipment in the spinning process. It is responsible for drafting, twisting, and winding semi-finished roving or sliver into fine yarn bobbins. On the roving frame, the sliver is transformed into roving after drafting and twisting. The combing machine then combs the fibers to produce combed sliver. The carding machine combines the sliver and improves its structure through card drafting. Subsequently, the roving is further twisted on the ring spinning frame to produce fine yarn. The output and quality of fine yarn reflect the overall level of each stage of the spinning process. For ease of use, the yarn needs to be guided by a yarn guide device.

[0003] In existing technology, guide rods on spinning frames typically use smooth stainless steel pipes to guide rovings, but they often lack a mechanism to fix the roving's guide path. Therefore, the roving suspended on the spindle inevitably encounters irregular friction during its descent, leading to excessive fuzz in the yarn and affecting its quality. Furthermore, this irregular friction can cause the roving to deviate from its conveying path, which is detrimental to the normal operation of the device. Utility Model Content

[0004] In view of this, the present invention provides a feeding positioning mechanism and a fine yarn machine. Its purpose is to limit the roving during the conveying process by adding a positioning component to the yarn guide rod, thereby ensuring the stability and straightness of the roving during the descent, reducing fuzz caused by friction, and improving the quality of the yarn.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A feeding and positioning mechanism includes a yarn guide rod and positioning components. The yarn guide rod is used to guide the roving conveying path, and the yarn guide rod is provided with a plurality of positioning components.

[0007] The positioning component includes a sleeve, an adjusting tube, and a limiting ring. The sleeve is fitted onto the yarn guide rod, and the two adjusting tubes are coaxially fitted onto the sleeve. Each of the two adjusting tubes has a limiting ring on its opposite side, and the two limiting rings arranged opposite each other form a groove for positioning the roving conveying path.

[0008] As a preferred technical solution, each of the mutually facing sides of the limiting rings is provided with a sponge layer.

[0009] Furthermore, the limiting ring is provided with a slot that is compatible with the sponge layer.

[0010] Furthermore, the inner wall of the slot is provided with a seepage hole, and the outer wall of the limiting ring is provided with a water inlet that communicates with the seepage hole.

[0011] Furthermore, the sleeve and the adjusting tube are connected by threads.

[0012] A fine yarn spinning frame includes a roving spool, a guide wheel, a yarn spool, and a feeding and positioning mechanism. The roving spool and the yarn spool are arranged opposite each other in the fine yarn spinning frame. The guide wheel is located between the roving spool and the yarn spool and is used to stretch the roving. The yarn guide rod is located between the roving spool and the guide wheel, and the groove is vertically opposite to the guide wheel.

[0013] Furthermore, it also includes a positioning frame for assembling the guide wheel, wherein the guide wheel includes two discs and a rotating shaft, wherein the two ends of the rotating shaft pass through the center of the two discs and are connected to the positioning frame.

[0014] Furthermore, the ratio of the inner diameter length of the rotating shaft to that of the wheel is 0.7 to 1.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0016] 1. By setting the limiting rings and adjusting tubes, the roving is placed between two oppositely set limiting rings when it comes into contact with the yarn guide rod, and the two limiting rings are attached to both sides of the roving. This achieves the purpose of limiting the horizontal movement of the roving, which helps to avoid large positional deviation of the roving on the yarn guide rod. At the same time, by adjusting the relative position between the two adjusting tubes, the width between the two limiting rings can be changed to accommodate rovings of different thicknesses.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] In existing technology, guide rods on spinning frames typically use smooth stainless steel pipes to guide rovings, but they often lack a mechanism to fix the roving's guide path. Therefore, the roving suspended on the spindle inevitably encounters irregular friction during its descent, leading to excessive fuzz in the yarn and affecting its quality. Furthermore, this irregular friction can cause the roving to deviate from its conveying path, which is detrimental to the normal operation of the device.

[0027] Therefore, in order to solve the above problems and achieve the function of maintaining the stability of roving during the conveying process and reducing the generation of fuzz, this utility model discloses a feeding and positioning mechanism, see reference. Figure 1 and Figure 2 The yarn guide rod 1 and the positioning assembly 2 are provided. The yarn guide rod 1 is used to guide the roving conveying path, and the yarn guide rod 1 is provided with a plurality of positioning assemblies 2. The positioning assembly 2 includes a sleeve 3, an adjusting tube 4 and a limiting ring 5. The sleeve 3 is sleeved on the yarn guide rod 1, and two adjusting tubes 4 are coaxially sleeved on the sleeve 3. A limiting ring 5 is provided on the opposite side of the two adjusting tubes 4. A groove for positioning the roving conveying path is formed between the two oppositely arranged limiting rings 5.

[0028] In this embodiment, the trough can limit the contact area of ​​the roving on the guide rod 1, so that the roving can only move within the trough during the conveying process, thereby effectively avoiding irregular friction with the guide rod 1 and large positional shifts during the conveying process.

[0029] In a specific implementation, when the roving comes into contact with the yarn guide rod 1, it is placed between two opposing limiting rings 5, and the two limiting rings 5 ​​are attached to both sides of the roving, so as to limit the horizontal movement of the roving and help avoid large positional deviations of the roving on the yarn guide rod 1.

[0030] Furthermore, for rovings of different thicknesses, the width of the trough can be changed by adjusting the relative position between the two adjusting tubes 4. Specifically, the sleeve 3 and the adjusting tube 4 are threadedly connected, allowing the user to adjust the width of the trough by rotating the adjusting tube 4 according to the diameter of the roving, thus accommodating rovings of different thicknesses. This improves the applicability of the feeding positioning mechanism, simplifies the adjustment process, and makes operation more convenient.

[0031] It should be noted that the sleeve 3 is fixed to the yarn guide rod 1 with screws. The user can disassemble and assemble the positioning component 2 with the screws. In this way, the user can assemble the corresponding number of positioning components 2 on the yarn guide rod 1 according to the amount of roving to be conveyed.

[0032] Meanwhile, in order to reduce the wear of the roving on the guide rod 1, the surface of the guide rod 1 is polished to ensure that its surface is smooth and reduce friction with the roving.

[0033] Example 2

[0034] Based on Example 1, in order to reduce the possibility of the roving being snapped due to hard contact between the roving and the limiting ring 5 during the descent, refer to... Figure 2 and Figure 3 The present invention also includes a sponge layer 6. Specifically, the limiting rings 5 ​​are provided with a sponge layer 6 on the side facing each other.

[0035] In this embodiment, the sponge layer 6 helps absorb the impact force generated when the roving descends, thereby buffering the contact pressure between the roving and the limiting ring 5 and protecting the roving from damage. This improves the protection effect on the roving, ensuring stability during the production process and the quality of the roving.

[0036] In one embodiment, the limiting ring 5 is provided with a slot 11 that matches the sponge layer 6, which improves the convenience of replacing the sponge layer 6. When the sponge layer 6 is worn or damaged due to long-term use, the user only needs to remove the sponge layer 6 from the slot 11 and then insert the new sponge layer 6 into the slot 11 without the need for tools, thereby ensuring the long-term stable operation of the feeding positioning mechanism and the continuous protection of the roving.

[0037] Furthermore, during the descent of the roving, friction between the roving and the guide rod 1 and the sponge layer 6 generates static electricity, posing a safety hazard. Therefore, the inner wall of the slot 11 is provided with drainage holes 11, and the outer wall of the limiting ring 5 is provided with a water inlet 12 connected to the drainage holes 11. Through these drainage holes 11 and water inlets 12, the user can inject water into the water inlet 12, allowing the drainage holes 11 to guide the water into the slot 11, thereby wetting the sponge layer 6 within the slot 11 to increase its conductivity and effectively neutralize or reduce static electricity generated by friction. This not only protects the roving from damage caused by static electricity but also avoids potential safety hazards caused by static electricity accumulation. In addition, by controlling the amount of water injected, the humidity of the sponge layer 6 can be adjusted, thereby improving its cushioning performance to adapt to the needs of different roving materials and production environments.

[0038] Example 3

[0039] Based on Embodiments 1 and 2, this utility model also provides a fine yarn spinning machine, including a roving spool 9, a guide wheel 8, a yarn spool 10, and a feeding and positioning mechanism. The roving spool 9 and the yarn spool 10 are arranged opposite to each other in the fine yarn spinning machine. The guide wheel 8 is located between the roving spool 9 and the yarn spool 10 and is used to stretch the roving. The yarn guide rod 1 is located between the roving spool 9 and the guide wheel 8, and the groove is vertically opposite to the guide wheel 8.

[0040] In this embodiment, the roving is connected to the positioning component and the guide wheel 8 in sequence from the roving roll 9 downwards. The roving is stretched into fine yarn by the rotation of the guide wheel 8 and introduced into the fine yarn roll 10.

[0041] In one embodiment, to improve the stretching effect of the guide roller 8 on the roving, a positioning frame for assembling the guide roller 8 is also included. The guide roller 8 includes two opposing discs and a rotating shaft. The two ends of the rotating shaft pass through the center of the two discs and are connected to the positioning frame. A gap is left between the two opposing discs. The roving is placed between the gap and fits against the rotating shaft. This arrangement can further reduce the positional deviation of the roving on the guide roller 8, thereby helping to improve the stretching effect.

[0042] As a preferred technical solution, the ratio of the inner diameter length of the shaft to that of the wheel is 0.7 to 1. This setting shortens the depth of the gap between the two wheels, thereby ensuring that the roving can be more evenly distributed on the surface of the shaft during the stretching process.

[0043] In summary, based on Embodiments 1 to 3, the working steps of the feeding positioning mechanism and the fine yarn spinning machine are as follows:

[0044] First, according to the required amount of roving to be conveyed, the corresponding number of sleeves 3 are fixed to the guide rod 1 with screws to complete the assembly of the positioning component 2. At the same time, according to the thickness of the roving, the width of the groove formed by the two limiting rings 5 ​​is adjusted by rotating the adjusting tube 4 (using the threaded connection between the sleeve 3 and the adjusting tube 4) to accommodate roving of different thicknesses, and to ensure that the surface of the guide rod 1 is polished to reduce wear of the roving.

[0045] Secondly, based on Embodiment 2, the limiting ring 5 with the sponge layer 6 is installed, and an appropriate amount of water is injected into the water inlet 12 on the outer wall of the limiting ring 5, so that the water is introduced into the slot 11 through the seepage hole 11 to wet the sponge layer 6, thereby increasing the conductivity of the sponge layer 6 to neutralize or reduce static electricity. At the same time, the humidity of the sponge layer 6 can be adjusted by controlling the amount of water injected to meet different needs. When the sponge layer 6 is worn or damaged due to long-term use, the old sponge layer 6 can be removed and replaced with a new sponge layer 6 without the aid of tools by using the slot 11 on the limiting ring 5 that is compatible with the sponge layer 6.

[0046] Finally, in embodiment three, the roving is connected from the roving roll 9 downwards to the guide rod 1 with positioning components and the guide wheel 8 in sequence. The rotation of the guide wheel 8 stretches the roving into fine yarn and introduces it into the fine yarn roll 10. The guide rod 1 is located between the roving roll 9 and the guide wheel 8, and the groove is vertically opposite to the guide wheel 8. The positioning frame that assembles the guide wheel 8 ensures that the guide wheel 8 works stably and reduces the positional deviation of the roving on the guide wheel 8. This completes the entire feeding positioning mechanism and the fine yarn machine's workflow, realizing stable roving conveying, stretching and yarn forming operations, ensuring the stability of the production process and the quality of the yarn.
