Description

Technical Field

[0001] This utility model belongs to the field of winding machine technology, and in particular relates to a friction roller for a winding machine. Background Technology

[0002] The function of a winding machine is to wind materials such as yarn and filament into regular packages. In the textile industry, it is mainly responsible for winding the nascent fibers spun by the spinning machine or the yarn after the spinning process into the form of yarn bobbins or cones after oiling, drafting and other treatments, so as to facilitate subsequent processing or storage.

[0003] The utility model patent with authorization announcement number CN222974559U discloses a variable stroke grooved cylinder structure for a winding machine, wherein the friction roller is used to press on the outside of the grooved cylinder to limit the yarn and prevent the yarn wrapped on the outside of the grooved cylinder from loosening or moving.

[0004] However, there are still some problems with the above-mentioned patent. During the operation of the winding machine, the yarn bundle breaks from time to time. The yarn bundle may get tangled on the friction roller, which affects the production efficiency. When cleaning the tangled yarn, it is necessary to cut the yarn bundle on the friction roller with a blade. However, the blade is easy to scratch the friction roller during the cutting process, thereby damaging the surface of the roller. Sometimes sharp edges will appear at the scratches on the surface of the roller. When the sharp edges come into contact with the yarn, they can easily cause the yarn to break. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a friction roller for a winding machine, comprising: Roller body, used for friction winding; Grooving: A groove is horizontally formed on the outer circumference of the roller body along the axial direction; Inserts are inserted into slots; A guide component, through which the insert is guided; The insert is fixedly connected to the roller body via a fixing component; The outer surface of the insert and the outer surface of the roller form a complete circle.

[0006] Furthermore, the guiding component includes: Slide bar, with slide bars on both sides of the insert bar; A groove is formed on the roller body, the groove is connected to the slot, and the slide bar is matched with the groove; The insert is positioned within the slot by moving left and right through the cooperation of a slider and a groove.

[0007] Furthermore, the fixing component includes: A semi-circular plate is fixedly provided at one end of the insert, and the semi-circular plate abuts against the end face of the roller body; The semi-circular plate is fixed to the end face of the roller body by screws.

[0008] Furthermore, the insert, slot, guide assembly, and fixing assembly are all symmetrically arranged in two sets.

[0009] Furthermore, it also includes: A limiting ring is fixedly sleeved on one end of the roller body; The outer circle formed by the two semicircular plates and the outer circle of the limiting ring are both larger than the outer circle of the roller.

[0010] Furthermore, the outer surfaces of both the roller body and the insert strip have a Teflon coating.

[0011] Furthermore, both the semicircular plate and the limiting ring have chamfered edges.

[0012] The beneficial effects of this utility model are as follows: 1. When filaments appear on the surface of the friction roller, the insert can be removed from the slot by disassembling the fixing component. Then, the filaments can be cut by slicing through the slot with a blade. This avoids scratching the outer surface of the roller body with the blade, solving the problem of easy damage to the roller body when cleaning filaments with traditional friction rollers, while ensuring the normal performance of the friction roller.

[0013] 2. It realizes the guiding and positioning function between the insert and the roller body, which not only makes the disassembly and assembly of the insert more convenient and labor-saving, but also ensures the positional accuracy of the insert after installation, and avoids unevenness of the friction roller surface due to the installation offset of the insert, which in turn affects the yarn winding quality.

[0014] 3. This design achieves reliable fixing between the insert and the roller body, preventing the insert from loosening or falling off during high-speed operation of the friction roller, thus ensuring the stability of the equipment. Simultaneously, the screw removal method is simple, allowing operators to quickly complete the disassembly and assembly of the insert, improving the efficiency of wire winding removal and reducing equipment downtime.

[0015] 4. The optimized stress performance of the friction rollers reduces vibration and noise during operation, improving equipment stability and service life. Simultaneously, the symmetrical component layout makes maintenance operations more flexible and convenient, reducing the difficulty of operation for staff and increasing production efficiency.

[0016] 5. It achieves axial positioning of the yarn, ensuring the stability of the yarn winding process and avoiding problems such as irregular winding or tangling caused by yarn deviation. At the same time, the cooperation between the positioning ring and the semi-circular plate forms a complete axial protection structure, further improving the performance of the friction roller.

[0018] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In the description of this application, it should be noted that the terminology used herein is only for describing specific implementations and is not intended to limit the exemplary implementations according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings indicate similar items, and therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings. Example 1

[0019] This embodiment provides a friction roller for a winding machine, comprising: Roller 1, which is used for friction winding; Groove 2: A groove 2 is horizontally formed on the outer circumference of the roller body 1 along the axial direction; Insert 3 is inserted into the slot 2; The guide component guides the insert 3; The fixing component is used to fix the insert 3 to the roller body 1. The outer surface of the insert 3 and the outer surface of the roller 1 form a complete circle.

[0020] In this technical solution, the roller body 1 is the core component of friction winding. The slot 2 on its outer circumference provides an installation base for the insert 3. The cooperation between the insert 3 and the slot 2 makes the friction roller form a detachable structure. The guide component ensures that the insert 3 moves along a fixed direction during installation and removal, preventing misalignment that could result in an uneven surface after installation; The fixing component ensures a stable connection between the insert 3 and the roller body 1, preventing the insert 3 from becoming loose during the operation of the friction roller; When cleaning the tangled wire, the insert strip 3 can be removed and the blade can be slid through the slot 2 to avoid touching the outer circle of the roller body 1. At the same time, after the tangled wire is wrapped around the friction roller, it is usually in a tight state. By removing the insert strip 3, the outline of the roller body 1 can be reduced, thereby making the tangled wire loose and easy to cut. After cleaning up the tangled yarn, insert strip 3 is reinstalled. The circular structure formed by insert strip 3 and the outer surface of roller body 1 ensures the stability of the friction roller in limiting the yarn and meets the requirements of the winding process for the flatness of the friction roller surface.

[0021] With this structural design, when tangled wires appear on the surface of the friction roller, the insert 3 can be removed from the slot 2 by disassembling the fixing component after the machine is stopped. Then, the tangled wires can be cut by slicing through the slot 2 with a blade, avoiding the blade from scratching the outer surface of the roller body 1. This solves the problem that the traditional friction roller is prone to damaging the roller body 1 when cleaning tangled wires, while ensuring the normal performance of the friction roller. Example 2

[0022] This embodiment provides a friction roller for a winding machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0023] Furthermore, the guiding component includes: Slide 4, both sides of the insert 3 have slide 4; A groove 5 is formed on the roller body 1, and the groove 5 is connected to the slot 2. The slide bar 4 is matched with the groove 5. The insert 3 is positioned in the slot 2 by moving left and right through the cooperation of the slide bar 4 and the slide groove 5.

[0024] In this technical solution, the sliding strips 4 on both sides of the insert 3 and the sliding groove 5 on the roller body 1 form a sliding fit structure. The through design of the sliding groove 5 and the slot 2 allows the insert 3 to be smoothly inserted into the slot 2 from one end face of the roller body 1.

[0025] This structural design enables the guiding and positioning function between the insert strip 3 and the roller body 1. This not only makes the disassembly and assembly of the insert strip 3 more convenient and labor-saving, but also ensures the positional accuracy of the insert strip 3 after installation, avoiding unevenness on the surface of the friction roller due to the installation offset of the insert strip 3, which in turn affects the yarn winding quality. Example 3

[0026] This embodiment provides a friction roller for a winding machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0027] Furthermore, the fixing component includes: A semi-circular plate 6 is fixedly provided at one end of the insert 3, and the semi-circular plate 6 abuts against the end face of the roller body 1. The semi-circular plate 6 is fixed to the end face of the roller body 1 by screws.

[0028] In this technical solution, the semi-circular plate 6 is fixedly connected to the insert strip 3. When the insert strip 3 is inserted into the slot 2, the semi-circular plate 6 and the end face of the roller body 1 are in close contact. The semi-circular plate 6 and the roller body 1 are fixed by screws, thereby realizing the stable installation of the insert strip 3 in the slot 2. The design of the semi-circular plate 6 serves a fixing function. At the same time, during installation, the semi-circular plate 6 abuts against the end face of the roller body 1, resulting in better stability. The screw connection method has the characteristics of convenient disassembly and reliable fixation, which meets the needs of rapid maintenance in the production process.

[0029] This structural design ensures reliable fixation between the insert strip 3 and the roller body 1, preventing the insert strip 3 from loosening or falling off during high-speed operation of the friction roller, thus guaranteeing the stability of the equipment operation. Simultaneously, the screws are easy to remove, allowing operators to quickly disassemble and reassemble the insert strip 3, improving the efficiency of wire entanglement removal and reducing equipment downtime. Example 4

[0030] This embodiment provides a friction roller for a winding machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0031] Furthermore, the insert 3, the slot 2, the guide component, and the fixing component are all symmetrically arranged in two sets.

[0032] In this technical solution, two sets of components are symmetrically arranged on the outer circumference of the roller body 1, making the overall structure of the friction roller more balanced and the force more uniform. The symmetrical design ensures that the friction roller will not vibrate due to the shift of the center of gravity during high-speed rotation, thus improving the stability of the equipment operation. At the same time, the arrangement of two sets of inserts 3 makes the cleaning of tangled wire more flexible. The inserts 3 on the corresponding side can be removed for targeted processing according to the location of the tangled wire, without having to remove both sets of inserts 3 at the same time, further improving maintenance efficiency.

[0033] This structural design optimizes the stress performance of the friction roller, reduces vibration and noise during operation, and improves the operational stability and service life of the equipment. At the same time, the symmetrical component layout makes maintenance operations more flexible and convenient, reduces the difficulty of operation for staff, and improves production efficiency. Example 5

[0034] This embodiment provides a friction roller for a winding machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0035] Furthermore, it also includes: Limiting ring 7, one end of the roller body 1 is fixedly sleeved with a limiting ring 7; The outer circles formed by the two semicircular plates 6 and the outer circles of the limiting ring 7 are both larger than the outer circles of the roller body 1.

[0036] In this technical solution, the limiting ring 7 is fixedly sleeved on one end of the roller body 1, and the structure formed by it and the two semi-circular plates 6 is located at both ends of the roller body 1. Because its outer diameter is larger than that of the roller body 1, it can axially limit the yarn during the winding process, preventing the yarn from moving to both ends under the drive of the friction roller, and avoiding situations where the yarn detaches from the friction roller or wraps around the end of the roller body 1. The limiting ring 7 can be fixed to the roller body 1 by welding or interference fit to ensure that it will not loosen during operation.

[0037] Meanwhile, since the friction roller also needs to be used in conjunction with the external grooved cylinder, the width between the limiting ring 7 and the semi-circular plate 6 is greater than the width of the grooved cylinder to avoid interference with its use.

[0038] This structural design achieves axial positioning of the yarn, ensuring stability during the yarn winding process and preventing problems such as irregular winding or tangling caused by yarn deviation. Simultaneously, the cooperation between the positioning ring 7 and the semi-circular plate 6 forms a complete axial protection structure, further enhancing the performance of the friction roller. Example 6

[0039] This embodiment provides a friction roller for a winding machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0040] Furthermore, the outer surfaces of both the roller body 1 and the insert 3 have a Teflon coating.

[0041] In this technical solution, both the outer surfaces of the roller body 1 and the insert strip 3 are coated with Teflon, which reduces the adhesion between the yarn and the friction roller surface, lowering the probability of yarn breakage and entanglement on the friction roller surface. Simultaneously, the low coefficient of friction reduces frictional damage to the yarn during winding, improving yarn quality. The wear resistance of the Teflon coating also extends the service life of the roller body 1 and the insert strip 3, reducing the frequency of maintenance and replacement.

[0042] This structural design reduces the probability of yarn entanglement at its source, while also reducing yarn wear and improving winding quality. The superior performance of the Teflon coating also extends the service life of the friction rollers, reducing equipment maintenance costs. Example 7

[0043] This embodiment provides a friction roller for a winding machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0044] Furthermore, both the semicircular plate 6 and the limiting ring 7 have chamfered edges.

[0045] In this technical solution, the edges of the semi-circular plate 6 and the limiting ring 7 are chamfered to remove sharp corners and prevent scratching damage to the yarn during winding. The chamfered design makes the edges of the semi-circular plate 6 and the limiting ring 7 smoother, preventing cutting force when in contact with the yarn and further protecting the yarn's integrity, reducing the occurrence of yarn breakage. At the same time, the chamfering also prevents workers from being scratched by sharp edges during maintenance operations, improving operational safety.

[0046] This structural design eliminates the sharp edges of the semi-circular plate 6 and the limiting ring 7, preventing scratch damage to the yarn, further reducing the probability of yarn breakage, and improving the yarn winding quality. At the same time, it also enhances the safety of equipment maintenance operations and reduces the operational risks for workers.
