Description

Technical Field

[0001] The utility model belongs to the technical field of yarn feeders, and in particular relates to a yarn fixing device for a yarn feeder. Background Art

[0002] With the development of the textile industry, automated production has become a trend, placing higher demands on the accuracy and stability of the yarn feeding system. The traditional manual method of fixing yarn is not only inefficient, but also easily causes the yarn to loosen or break, seriously affecting product quality and production efficiency. Currently, several commonly used yarn fixing methods include the use of spring clamping mechanisms and magnetic adsorption fixing structures. The former uses spring pressure to maintain the yarn position, but the spring is prone to fatigue failure due to long-term stress, resulting in a decrease in clamping force; while the latter can avoid clamping damage to a certain extent, the magnetic field strength is difficult to adjust and has poor adaptability to yarns of different materials. Existing yarn fixing devices generally have short service lives and are prone to aging. They also cause knots and breakage during yarn transportation, affecting production efficiency. Utility Model Content

[0003] The purpose of the utility model is to solve the above-mentioned technical problems and provide a yarn fixing device for a yarn feeder, so as to avoid knotting and breaking of the yarn in this process, thereby achieving the effect of improving production efficiency.

[0004] In view of this, the utility model provides a yarn fixing device for a yarn feeder, comprising a yarn feeder, and also comprising: a mounting frame, the mounting frame being arranged on the yarn feeder; a wire ring, the wire ring being arranged on the mounting frame; a wire inlet, the wire inlet being designed on the mounting frame; a wire inlet fixer, the wire inlet fixer being movably arranged on one side of the mounting frame; and a wire outlet fixer, the wire outlet fixer being arranged at the bottom of the yarn feeder.

[0005] In this technical solution, the yarn passes through the wire loop and enters the wire inlet. The yarn passes through the wire inlet and enters the wire inlet fixture. The wire inlet fixture fixes the path of the yarn entering the yarn feeder. The yarn passes through the wire inlet fixture and enters the yarn feeder. The yarn passes through the yarn feeder and enters the wire outlet fixture. The wire outlet fixture fixes the path of the yarn entering the yarn feeder. The amount of yarn output by the yarn feeder varies during operation. To prevent the yarn from knotting and breaking during this process, the wire inlet fixture and the wire outlet fixture are provided to fix the yarn path, thereby improving production efficiency.

[0006] In the above technical solution, further, the incoming line fixer includes a first lever bar, the first lever bar is movably provided with a first mounting hole, the first mounting is rotatably provided on the first fixed column, the two first fixed columns are symmetrically provided on the mounting frame, the other first fixed column is rotatably provided with a second mounting hole, the second mounting hole is provided on the second lever bar, the first lever bar is provided with a first limiting ring at the bottom, and the second lever is provided with a second limiting ring at the bottom.

[0007] In this technical solution, the yarn passes through the wire inlet and passes through the first limiting ring and the second limiting ring in sequence. The first lever bar and the second lever bar rotate relative to each other under the influence of gravity from the top. The first limiting ring and the second limiting ring pull the yarn against each other to keep the yarn in a taut state, thereby preventing the yarn from getting entangled and knotted when it is relaxed.

[0008] In the above technical solution, further, a first mounting plate is fixedly provided at the bottom of the first lever bar, a second mounting plate is fixedly provided at the bottom of the second lever bar, the first mounting plate is provided with a first limiting ring in a linear array along the length direction of the first mounting plate, the second mounting plate is provided with a second limiting ring in a linear array along the length direction of the second mounting plate, and the first limiting ring and the second limiting ring are staggered with each other.

[0009] In this technical solution, the first and second limiting rings are increased in number to improve the handling of slack caused by the withdrawal of excess yarn. When the length of the withdrawn yarn is appropriate, the first and second limiting rings act on the top of the first and second lever bars to pull the yarn tightly, and the yarn path forms multiple 'S' shapes. When the length of the withdrawn yarn is excessive, the 'S'-shaped path of the yarn becomes wider, and when the length of the withdrawn yarn is excessive, the 'S'-shaped path of the yarn becomes narrower. The first and second limiting rings change the yarn path as the amount of yarn withdrawn changes, preventing the yarn from becoming entangled when it is in a slack state.

[0010] In the present technical solution, further, it includes a first contact block, which is symmetrically arranged on the mounting frame, and the first contact block is arranged corresponding to the bottom of the first mounting plate and the second mounting plate.

[0011] In this technical solution, if the yarn breaks during transport, the first limiting ring and the second limiting block no longer pull on the yarn, and the tension is lost. Gravity acting on the tops of the first and second lever bars causes the first and second mounting plates to rotate, and the bottoms of the first and second mounting plates contact the first contact block, causing the entire yarn feeder to sound an alarm. This provides a timely alarm for yarn breaks, preventing maximum losses during production.

[0012] In the above technical solution, further, configuration blocks are provided at the top of the first lever bar and the second lever bar, and the two grids of the configuration blocks are staggered with each other.

[0013] In this technical solution, the increase in weight of the counterweight block further increases the rotational power of the first lever bar and the second lever bar, improves durability during use, and avoids performance degradation caused by aging.

[0014] In the above technical solution, further, the wire outlet fixer includes a support plate, the support plate is arranged at the bottom of the yarn feeder, a third limiting ring is vertically fixedly provided at the bottom of the support plate, a second fixing column is fixedly provided between the two support plates, the second fixing column is rotatably provided with a third mounting hole, the third mounting hole is provided on one side of the third lever bar, a fourth limiting ring is fixedly provided on the other side of the third lever bar, a counterweight bar is provided at the bottom away from one side of the third lever bar, and a stepped weight block is provided on the top of the counterweight bar.

[0015] In this technical solution, the yarn passes under the third limiting ring and through the fourth limiting ring. Under the gravity of the stepped weight, the third lever bar drives the fourth limiting ring to rotate upward. The fourth limiting ring cooperates with the third limiting ring to pull and tighten the yarn during delivery. This simple structure prevents the yarn from being broken due to excessive speed during delivery.

[0016] In the above technical solution, further, a second contact block is provided on the support plate.

[0017] In this technical solution, if a yarn breaks during delivery, the fourth stop ring, driven by the configured weight bar and trapezoidal weight block, rotates upward. When the fourth stop ring contacts the second contact block, it stops rotating and the yarn feeder sounds an alarm. This provides a timely alarm for yarn breakage, minimizing losses during production.

[0018] The beneficial effects of the utility model are:

[0019] 1. By setting the first limiting ring and the second limiting ring, the yarn path changes when the amount of yarn drawn out changes, thereby preventing the yarn from being entangled when it is relaxed.

[0020] 2. By setting the configuration block, the increase in weight of the counterweight block further increases the rotational power of the first lever bar and the second lever bar, thereby improving durability during use and avoiding performance degradation caused by aging.

[0021] 3. By setting the second contact block, the yarn breakage can be promptly alarmed, avoiding maximum loss in the production process. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Example 1:

[0035] This embodiment provides a yarn fixing device for a yarn feeder 1, such as Figure 1As shown, it includes a yarn feeder 1, and also includes: a mounting frame 2, the mounting frame 2 is set on the yarn feeder 1; a wire loop 5, the wire loop 5 is set on the mounting frame 2; a wire inlet 6, the wire inlet 6 is designed and mounted on the mounting frame 2; a wire inlet fixture 3, the wire inlet fixture 3 is movably set on one side of the mounting frame 2; and a wire outlet fixture 4, the wire outlet fixture 4 is set at the bottom of the yarn feeder 1. The yarn passes through the wire loop 5 and enters the wire inlet 6, the yarn passes through the wire inlet 6 and enters the wire inlet fixture 3, the wire inlet fixture 3 fixes the path of the yarn entering the yarn feeder 1, the yarn passes through the wire inlet fixture 3 and enters the yarn feeder 1, the yarn passes through the yarn feeder 1 and enters the wire outlet fixture 4, the wire outlet fixture 4 fixes the path of the yarn entering the yarn feeder 1. The amount of yarn output by the yarn feeder 1 varies during operation. In order to prevent the yarn from knotting and breaking during this process, an inlet fixture 3 and an outlet fixture 4 are provided to fix the yarn path, thereby improving production efficiency.

[0036] like Figure 3 As shown, the feeder fixture 3 includes a first lever bar 9, which is movably provided with a first mounting hole 10. The first mounting hole is rotatably provided on a first fixing column 7. Two first fixing columns 7 are symmetrically provided on the mounting frame 2. Another first fixing column 7 is rotatably provided with a second mounting hole 16. The second mounting hole 16 is provided on a second lever bar 15. A first limiting ring 12 is provided at the bottom of the first lever bar 9, and a second limiting ring 18 is provided at the bottom of the second lever bar. The yarn passes through the feeder port 6 and passes through the first limiting ring 12 and the second limiting ring 18 in sequence. The first lever bar and the second lever bar 15 rotate relative to each other under the influence of gravity from the top. The first limiting ring 12 and the second limiting ring 18 pull the yarn against each other, keeping the yarn in a taut state and preventing the yarn from tangling and knotting when it is relaxed.

[0037] like Figure 3As shown, a first mounting plate 11 is fixedly mounted at the bottom of the first lever bar 9, and a second mounting plate 17 is fixedly mounted at the bottom of the second lever bar 15. The first mounting plate 11 is provided with a linear array of first limiting rings 12 along the length of the first mounting plate 11, and the second mounting plate 17 is provided with a linear array of second limiting rings 18 along the length of the second mounting plate 17. The first limiting rings 12 and the second limiting rings 18 are arranged in an alternating manner. The increased number of first limiting rings 12 and second limiting rings 18 improves the handling of slack caused by excess yarn withdrawal. When the length of the withdrawn yarn is appropriate, the first limiting rings 12 and second limiting rings 18 at the top of the first lever bar 9 and the second lever bar 15 act to pull the yarn tautly, forming multiple "S"-shaped paths. When the length of the withdrawn yarn is excessive, the "S"-shaped paths of the yarn become wider, and when the length of the withdrawn yarn is excessive, the "S"-shaped paths of the yarn become narrower. The first limiting ring 12 and the second limiting ring 18 change the yarn path as the amount of yarn drawn out changes, thereby preventing the yarn from being entangled when the yarn is in a relaxed state.

[0038] like Figure 2 As shown, the yarn feeder 1 includes a first contact block 8, which is symmetrically arranged on the mounting frame 2 and corresponds to the bottom of the first mounting plate 11 and the second mounting plate 17. When the yarn breaks during transport, the first limit ring 12 and the second limit block no longer pull on the yarn, and the tension is lost. Gravity acts on the top of the first and second lever bars 15, causing the first and second mounting plates 11 and 17 to rotate. The bottoms of the first and second mounting plates 11 and 17 contact the first contact block 8, and the entire yarn feeder 1 starts to alarm. The yarn break can be promptly alarmed, avoiding maximum losses during the production process.

[0039] like Figure 3 As shown, the tops of the first and second lever bars 15 are provided with configuration blocks, and the two configuration blocks are arranged in an interlaced manner. The increased weight of the counterweight blocks 13 further increases the rotational power of the first and second lever bars 15, improves durability during use, and avoids performance degradation caused by aging.

[0040] like Figure 4As shown, the outlet fixture 4 includes a support plate 19, which is mounted on the bottom of the yarn feeder 1. A third retaining ring 24 is vertically fixed to the bottom of the support plate 19. A second fixing post 25 is fixed between the two support plates 19. The second fixing post 25 is rotatably provided with a third mounting hole. The third mounting hole is located on one side of a third lever bar 20. A fourth retaining ring 21 is fixed to the other side of the third lever bar 20. A counterweight bar 22 is located at the bottom of the third lever bar 20 on the far side, and a stepped weight block 23 is installed on the top of the counterweight bar 22. The yarn passes under the third retaining ring 24 and through the fourth retaining ring 21. Under the action of the gravity of the stepped weight block 23, the third lever bar 20 drives the fourth retaining ring 21 to rotate upward. The fourth retaining ring 21 cooperates with the third retaining ring 24 to pull and tighten the yarn during delivery. This simple structure prevents the yarn from being broken due to excessive speed during delivery.

[0041] like Figure 5 As shown, the support plate 19 is provided with a second contact block 26. If a yarn break occurs during yarn delivery, the fourth limiting ring 21 rotates upward under the action of the configured weight bar and trapezoidal weight block. When the fourth limiting ring 21 contacts the second contact block 26, rotation stops, and the yarn feeder 1 sounds an alarm. This provides a timely alarm for yarn breakage, minimizing losses during production.

[0042] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
