Therefore, the above terms should not be understood as limiting the present invention.

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments cannot be described one by one here, but the embodiments of the present invention are not therefore limited to the following embodiments.

[0025] like Figure 1 As shown, according to one embodiment of the present invention, a device for parallel arrangement of micron-diameter filament fibers of the present invention comprises: a support structure 1, a clamping structure 2 installed on the support structure 1 for arranging fiber monofilaments; wherein the support structure 1 is provided with a plurality of parallel guide rails 11; the clamping structure 2 is supported on the upper side of the guide rails 11 in a one-to-one correspondence with the guide rails 11, thereby, the fiber monofilaments can be regularly clamped by the provided clamping structure 2 for preparing the corresponding fiber dry yarn; wherein, the interval between adjacent guide rails 11 can be set according to the size of the fiber dry yarn to be prepared, which will not be repeated here. In this embodiment, two guide rails 11 are provided, and correspondingly, two clamping structures 2 are also provided for corresponding arrangement with the guide rails 11. Of course, in other arrangement modes, the laying range can be expanded by arranging more guide rails 11 and corresponding clamping structures 2 side by side, thereby fully improving the flexibility of use of the present invention.

[0026] Combination Figure 1 and Figure 2As shown, in this embodiment, the clamping structure 2 includes: an elastically stretchable elastic matrix 21; wherein, a clamping groove 211 for arranging fiber monofilaments is provided on the upper side of the elastic matrix 21; the extension direction of the clamping groove 211 is perpendicular to the length direction of the elastic matrix 21, so that, in order to facilitate the arrangement of the fiber monofilaments, the clamping groove 211 has an opening for installing the limiting monofilament on the upper side of the elastic matrix 21; further, in order to facilitate the arrangement of the fiber monofilaments, the opposite ends of the clamping groove 211 also form openings on the opposite sides of the elastic matrix 21, thereby ensuring the reliable arrangement of the fiber monofilaments. In this embodiment, when the elastic matrix 21 is at a free length, the interval between adjacent clamping grooves 211 is the interval distance between the fibers in the fiber dry yarn to be prepared. Further, in order to ensure the parallelism between adjacent fiber monofilaments, the parallelism error between adjacent clamping grooves 211 is at the micron level (such as less than 10μm), thereby effectively ensuring the arrangement accuracy required in the preparation process.

[0027] In this embodiment, one end of the elastic base 21 is connected to one end of the guide rail 11, and the other end can be stretched and moved along the guide rail 11; thus, a force can be applied to the stretchable end of the elastic base 21 to generate a corresponding extension along the guide rail 11, thereby making it easier to arrange the corresponding fiber monofilaments on the elastic base 21. Furthermore, when the elastic base 21 is stretched, the opening of the clamping groove 211 is enlarged to facilitate the arrangement of the fiber monofilaments (see Figure 3 and Figure 4 ), when the elastic matrix 21 recovers its free length, the clamping groove 211 recovers elastically to clamp and fix the arranged fiber monofilaments (see Figure 5 ).

[0028] In this embodiment, the clamping groove 211 can be configured to have a rectangular cross-sectional shape (see Figure 2 ), trapezoid, rhombus, circle, triangle (see Figure 7 ) groove structure; wherein, the maximum position of the size of the clamping groove 211 is set to match the radial size of the arranged fiber monofilament, thereby achieving reliable clamping of the fiber monofilament when the clamping groove 211 returns to its initial state.

[0029] In this embodiment, the side surfaces of the clamping groove 211 on the opposite sides for clamping the fiber monofilament can be set as planes, and the plane error of the two planes is less than 1μm, and the parallelism error between the two planes is also in the micron level (such as less than 10μm), thereby achieving reliable clamping of the fiber monofilament with a small diameter. Of course, in different embodiments, wave-like protrusions that can be mutually offset and embedded can be further set on the side surfaces on the opposite sides of the clamping groove 211, thereby, when clamping the fiber monofilament, further reliable restriction of the fiber monofilament can be achieved based on the mutually matching and embedded wave-like protrusions; wherein, the wave-like protrusion can be set as a rectangular wave-like protrusion, a triangular wave-like protrusion, a trapezoidal wave-like protrusion, etc., and its setting method can be selected according to actual needs, which will not be repeated here.

[0030] like Figure 6 As shown, according to one embodiment of the present invention, the elastic matrix 21 satisfies: the length of the elastic matrix 21 when stretched is 5 to 10 times the free length of the elastic matrix 21.

[0031] Through the above-mentioned arrangement, the stretched length of the elastic matrix 21 is within the range of 5 to 10 times the free length, so that the elongation range of the elastic matrix 21 can be effectively increased, thereby being able to more flexibly control the stretched length of the elastic matrix 21, so that the opening of the clamping groove 211 is flexible and controllable, thereby facilitating the arrangement of fiber monofilaments of different sizes, and effectively ensuring the flexibility and applicability of the present invention.

[0032] like Figure 6 As shown, according to one embodiment of the present invention, the elastic base 21 is a columnar structure with a regular cross section. In this embodiment, the elastic base 21 adopts a columnar structure with a flat upper side surface, thereby, it is convenient to set the clamping groove 211 on the upper side of the elastic base 21, which is more beneficial to improving the positioning accuracy and processing accuracy of the clamping groove 211. In this embodiment, the cross-sectional shape of the elastic base 21 can be set to a rectangle, thereby, the length of the clamping groove 211 can be adapted to the width of the elastic base 21, thereby ensuring that the clamping groove 211 has a sufficient support length, and reliable and stable support for the fiber filaments can be achieved.

[0033] Combination Figure 1 , Figure 3 and Figure 5As shown, according to one embodiment of the present invention, the clamping structure 2 also includes: a first base fixing member 22 and a second base fixing member 23 arranged at opposite ends of the elastic base 21; wherein the first base fixing member 22 and the second base fixing member 23 are respectively fixedly connected to the ends of the elastic base 21, and the first base fixing member 22 and the second base fixing member 23 are respectively coaxially arranged with the elastic base 21; in this embodiment, the first base fixing member 22 and the second base fixing member 23 can both be set as plate-like structural members, and they are bonded to achieve reliable fixation with the ends of the elastic base 21, thereby ensuring that the first base fixing member 22 and the second base fixing member 23 are respectively connected to the elastic base 21 tightly and reliably, so as to achieve stability during repeated use.

[0034] In this embodiment, a first connection structure for detachably connecting with the end of the guide rail 11 is provided on the side of the first base fixing member 22 away from the elastic base 21; a second connection structure is provided on the side of the second base fixing member 23 away from the elastic base 21. The first connection structure and the second connection structure can be conveniently disassembled and assembled between the clamping structure 2 and other structures, which greatly improves the flexibility of the present invention and allows it to be replaced according to fiber dry yarns of different sizes.

[0035] Combination Figure 1 , Figure 3 and Figure 5 As shown, according to one embodiment of the present invention, along the length direction of the elastic substrate 21, the end surface error of the first substrate fixing component 22 at two opposite ends is less than 1 μm, and the end surface parallelism error of the first substrate fixing component 22 at two opposite ends is in the micron level (such as less than 10 μm), and the end surface error of the second substrate fixing component 23 at two opposite ends is less than 1 μm, and the end surface parallelism error of the second substrate fixing component 23 at two opposite ends is in the micron level (such as less than 10 μm).

[0036] Through the above arrangement, the accuracy of the positioning and mounting surfaces of the first substrate fixing member 22 and the second substrate fixing member 23 is effectively guaranteed, and the bonding tightness between the first substrate fixing member 22 and the second substrate fixing member 23 and the end surface of the elastic substrate 21 can be fully guaranteed, which is especially beneficial for eliminating the gap that may exist at the bonding position. In addition, through the above arrangement, the connection accuracy can be further guaranteed, which is more beneficial for accurately controlling the stretching length of the elastic substrate 21.

[0037] Combination Figure 1 , Figure 3 and Figure 5As shown, according to one embodiment of the present invention, a fixing seat 111 for connecting the first base fixing member 22 is provided at one end of the guide rail 11, and a control paddle 112 for connecting the second base fixing member 23 and capable of adjusting the position is provided on the guide rail 11; wherein the fixing seat 111 and the clamping structure 2 are on the same side of the guide rail 11, so that the fixing seat 111 is opposite to the first base fixing member 22, thereby facilitating the connection between the fixing seat 111 and the first base fixing member 22; specifically, the fixing seat 111 is provided with a first fixing structure corresponding to the first connecting structure; wherein the first fixing structure is a through hole, the first connecting structure is a threaded hole, and the fixing seat 111 and the first base fixing member 22 are screwed together based on a threaded connector passing through the first fixing structure.

[0038] like Figure 8 As shown, in the present embodiment, the control paddle 112 is slidably connected to the guide rail 11; wherein, the control paddle 112 is arranged relative to the second base fixing member 23 to facilitate the connection with the second base fixing member 23; accordingly, the control paddle 112 is provided with a second fixing structure corresponding to the second connection structure, wherein the second fixing structure is a through hole, and the second connection structure is a threaded hole, thereby, the control paddle 112 and the second base fixing member 23 are screwed together with the second connection structure based on the threaded connector passing through the second fixing structure.

[0039] Furthermore, in order to facilitate the positioning of the control paddle 112 after it is moved into position, a position locking piece corresponding to the guide rail 11 may be provided on the control paddle 112. In the present embodiment, the control paddle 112 is in a plate-like structure as a whole, and is slidably connected to the guide rail 11 by sleeve arrangement. Specifically, a sliding through hole matching the guide rail 11 is provided on the control paddle 112, so that the control paddle 112 and the guide rail 11 can be sleeved, wherein the sliding through hole on the control paddle 112 and the guide rail 11 slide by a clearance fit. In the present embodiment, the sliding through hole is located below the second fixed structure.

[0040] In this embodiment, the position locking member is arranged corresponding to the sliding through hole, wherein a threaded hole penetrating the control paddle 112 can be arranged on the side wall of the sliding through hole, and accordingly, the position locking member can adopt a threaded connecting member, and then it can be screwed with the threaded hole to achieve abutment or disengagement with the guide rail 11 to achieve locking or unlocking the position of the control paddle 112.

[0041] In this embodiment, the threaded hole is arranged on the side of the control paddle 112 facing away from the other guide rail 11; thus, the arranged position locking member can be conveniently operated to improve the convenience of use of the present invention. In another embodiment, the threaded hole is arranged on the side of the control paddle 112 facing the other guide rail 11; thus, the position locking members of the control paddles 112 on the two adjacent guide rails 11 can be opposite to each other, and thus, the synchronous locking and synchronous unlocking of the two relative control paddles 112 can be realized by driving the control link by connecting the control link and other structures between the relative position locking members, which greatly solves the problem of synchronous locking and unlocking of the two spaced control paddles 112, effectively ensures its synchronization performance and improves the speed of synchronous operation, which is more beneficial to ensuring the fiber arrangement effect of the present invention.

[0042] Combination Figure 1 , Figure 3 and Figure 5 As shown, according to one embodiment of the present invention, the plane error of the side of the fixing seat 111 opposite to the first substrate fixing member 22 is less than 1 μm, and the side parallelism errors of the fixing seat 111 on opposite sides are in the micron level (e.g., less than 10 μm); the plane error of the side of the control paddle 112 opposite to the second substrate fixing member 23 is less than 1 μm, and the side parallelism errors of the control paddle 112 on opposite sides are in the micron level (e.g., less than 10 μm).

[0043] The above arrangement effectively ensures the matching accuracy between the fixing seat 111 and the first base fixing member 22 and the matching accuracy between the control paddle 112 and the second base fixing member 23, which is more beneficial to improving the elongation control accuracy of the present invention.

In this embodiment, the connecting beam 12, the guide rail 11 and the fixing seat 111 are integrally formed, thereby realizing the overall processing and forming of the support structure 1, thereby conveniently ensuring the forming accuracy of the overall structure, and furthermore, being more beneficial to ensuring the precision of the prepared fiber dry yarn.

[0045] Furthermore, along the length direction of the guide rail 11, a scale for marking the position of the control paddle 112 is provided on the side of the guide rail 11, which effectively ensures the synchronous elongation accuracy of the multiple elastic substrates 21 and further improves the molding accuracy of the present invention.

[0046] Combination Figure 1 , Figure 3 and Figure 5 As shown, according to one embodiment of the present invention, the clamping structure 2 can achieve stretching of the elastic base 21 based on manually driving the second base fixing member 23 to move along the guide rail 11.

In this embodiment, the ends of the fiber monofilament and the weights are fixed to each other by bonding to ensure the reliability of the connection. In this embodiment, the selection criteria of the weights are: when the fiber monofilament can be straightened, the mass of the weights is as small as possible to avoid damage to the fiber monofilament, and to avoid the influence of the total mass of all weights on the retraction of the elastic matrix 21 after the fiber monofilament is arranged, which can effectively ensure the performance of the elastic matrix 21.
