[0027] The exemplary embodiments will be described in detail herein with reference to the accompanying drawings. In the following description, unless otherwise indicated, like numbers in the different drawings represent the same or similar elements. The following exemplary embodiments described in the detailed description are not meant to be an all-inclusive description of all aspects of the application. Rather, they are merely examples that can illustrate some aspects of the application as detailed in the appended claims.

[0028] In the field of carbon fiber production, the tightness and end face flatness of the fiber yarn after spooling are extremely critical technical indicators. Once these indicators do not meet the standards, a series of problems will be caused during the fiber yarn transfer and carbonization unwinding process, affecting the subsequent processing, or causing the entire spool of fiber yarn to be scrapped and unable to be put into use, greatly increasing the production cost.

[0029] The traditional unwinding method is to rotate the unwinding frame. When the spooled fiber yarn that does not meet the technical indicators is rewound, this method has obvious defects. The rotation of the unwinding frame can easily cause the spooled fiber yarn to be further deformed and loose, making it difficult to smoothly perform the rewinding, severely restricting the product quality and production efficiency, and causing waste of resources and economic losses.

[0030] Among them, the rewinding refers to the operation process of rewinding the fiber yarn that does not meet the standards after unwinding based on the initial winding that does not meet the requirements, to form a standard spool of fiber yarn for use in the carbonization process.

[0031] In order to solve the technical problems existing in the related art, the present application provides an unwinding and winding device, which comprises a frame assembly 1, a winding assembly 2, an unwinding assembly 3 and a guide assembly 4.

[0032] The frame body assembly 1 is a support structure of the whole device, can stably fix other assemblies, ensures the relative position of each assembly in the running process is accurate, and is usually made of high-strength metal material such as aluminum alloy or steel to ensure sufficient strength and rigidity. According to the actual needs of the fiber unwinding process, the frame body assembly 1 is arranged as a plurality of annular frames, which jointly support the winding assembly 2, the fiber unwinding assembly 3 and the guide wire assembly 4 and the like.

[0033] The fiber unwinding assembly 3 includes a fiber bobbin to be processed and realizes the fiber unwinding operation of the fiber 5. The fiber unwinding assembly 3 revolves around the rotation point without rotation, and in the revolving process, the fiber 5 is gradually unwound from the fiber unwinding assembly 3. That is, the fiber unwinding assembly 3 makes a circular motion on the frame body assembly 1 to unwind the fiber 5. The fiber unwinding assembly 3 revolves to unwind the fiber, compared with the technical solution of realizing fiber unwinding by rotation in the related art, avoids the problems of fiber 5 deformation and loosening caused by traditional rotation unwinding, ensures that the fiber 5 is stably unwound in the unwinding process, provides guarantee for subsequent accurate guidance of the fiber 5 to the winding assembly 2 by the guide wire assembly 4 to realize high-quality winding, and further improves the winding quality of the fiber bobbin and reduces the waste yarn rate.

[0034] The winding assembly 2 is arranged on the frame body assembly 1, and the central axis of the winding assembly 2 is the winding shaft, and the rotation point is located on the winding shaft, that is, the fiber unwinding assembly 3 revolves around the winding assembly 2. The winding assembly 2 is used for winding the fiber 5 guided by the guide wire assembly 4 to form a required bobbin. The winding assembly 2 includes a central shaft which is detachably arranged at the middle position of the frame body assembly 1, facilitating replacement of the central shaft. The detachable arrangement can be bolted or clamped. After the central shaft is installed on the frame body assembly 1, the central shaft no longer rotates, so that it stably receives the winding of the fiber 5.

[0035] The guide wire assembly 4 is arranged on the frame body and revolves around the rotation point, that is, revolves around the winding assembly 2. The fiber 5 unwound from the fiber unwinding assembly 3 is wound on the winding assembly 2 after passing through the guide wire assembly 4. In the radial direction of the circle formed by the revolution of the fiber unwinding assembly 3, the guide wire assembly 4 can be located on the inner side of the radial direction or on the outer side of the radial direction, and of course the guide wire assembly 4 can also have the same radius as the circle formed by the revolution of the fiber unwinding assembly 3. The guide wire assembly 4 is used to guide the fiber 5, so that the fiber 5 is smoothly wound on the winding assembly 2 from the fiber unwinding assembly 3, and plays a role in adjusting the tension of the fiber 5. The tension of the fiber 5 can be adjusted by adjusting the revolution speed of the guide wire assembly 4 and the fiber unwinding assembly 3. When the fiber 5 is loose, the revolution speed of the guide wire assembly 4 or the fiber unwinding assembly 3 is adjusted, and the distance between the guide wire assembly 4 and the fiber unwinding assembly 3 is increased to tension the fiber 5; when the fiber 5 is too tight, the revolution speed of the guide wire assembly 4 or the fiber unwinding assembly 3 is adjusted, and the distance between the guide wire assembly 4 and the fiber unwinding assembly 3 is reduced to loosen the fiber 5.

[0036] A fiber yarn unwinding and winding device comprises a frame assembly 1, an unwinding assembly 3, a winding assembly 2 and a guide assembly 4 arranged on the frame assembly 1, and the fiber yarn 5 on the unwinding assembly 3 is wound on the winding assembly 2 through the guide assembly 4. The unwinding assembly 3 and the guide assembly 4 revolve around the rotation point, and the central axis of the winding assembly 2 is the winding shaft, and the rotation point is located on the winding shaft.

[0037] The revolution of the unwinding assembly 3 in the present application avoids the deformation, loosening and even complete opening of the fiber yarn 5, and ensures the stable unwinding of the fiber yarn 5. The guide assembly 4 enables the fiber yarn 5 to be smoothly wound on the winding assembly 2, and simultaneously performs flattening and tension adjustment on the fiber yarn 5, thereby ensuring the consistent tension of the fiber yarn 5. The present application unwinds and secondarily winds the non-standard fiber yarn 5 on the spindle, thereby producing the standard fiber yarn 5 on the spindle, improving the product utilization rate, greatly reducing the amount of waste yarn and reducing economic losses.

[0038] In some embodiments, the frame assembly 1 comprises a circular track 11 coaxially arranged with the winding assembly 2, and the center of the circular track 11 is located on the central axis of the winding assembly 2, which is the rotation point. The circular track 11 is made of wear-resistant materials such as alloy steel or metal materials with surface hardening treatment, so as to ensure that the movement accuracy of the unwinding assembly 3 will not be affected by wear during long-term use. The unwinding assembly 3 is slidingly arranged in the circular track 11, and slides along the circular track 11 to realize the revolution around the winding assembly 2.

[0039] The circular track 11 provides an accurate movement track for the revolution of the unwinding assembly 3, thereby ensuring the movement accuracy of the unwinding assembly 3. The accurate movement track enables the fiber yarn 5 to leave the unwinding assembly 3 at a stable speed during the unwinding process.

[0040] In some embodiments, the unwinding assembly 3 comprises an unwinding shaft and a sliding block, the unwinding shaft is wound with the unqualified fiber yarn 5, the sliding block is slidingly arranged in the circular track 11, and the unwinding shaft is detachably arranged on the sliding block. The detachable connection mode can be bolt connection or clamping block connection, and the axis of the unwinding shaft is parallel to the winding shaft.

[0041] The detachable setting of the yarn withdrawing shaft can quickly and conveniently replace the yarn withdrawing shaft in the production process, thereby improving the production efficiency. The setting of the sliding block and the circular track 11 together ensures the stability of the yarn withdrawing assembly 3 in the yarn withdrawing process, which helps the uniformity of the yarn withdrawing speed and provides stable fiber yarn 5 supply for the subsequent winding process. The axis of the yarn withdrawing shaft is parallel to the winding shaft, which ensures the relative stability of the path of the fiber yarn 5 in the unwinding and winding processes, reduces the deviation and twisting of the fiber yarn 5, and makes the fiber yarn 5 arranged more neatly and closely on the winding assembly 2, thereby improving the winding quality and reducing the product quality problems caused by the irregular arrangement of the fiber yarn 5, such as the inconsistent tightness of the yarn shaft and the uneven end face.

[0042] In some embodiments, the yarn guiding assembly 4 includes a tensioning wheel 41, which revolves around the winding assembly 2 with the revolving point as the center, and the axis of the tensioning wheel 41 is parallel to the winding shaft. The fiber yarn 5 withdrawn from the yarn withdrawing assembly 3 is wound on the tensioning wheel 41, and in order to make the fiber yarn 5 move more smoothly, the number of winding turns is preferably less than one turn, and in another embodiment, it can be greater than one turn, but it is necessary to ensure the smooth movement of the fiber yarn 5.

[0043] In order to ensure the stable revolution of the yarn guiding assembly 4, the frame assembly 1 can also include a first track 12, which is circular, and the center of the first track 12 is on the winding shaft. The tensioning wheel 41 is arranged on the first track 12 through the first sliding block.

[0044] In one embodiment, the tensioning wheel 41 does not rotate, which simplifies the structure and improves stability. In another embodiment, the tensioning wheel 41 rotates, which can reduce the wear of the fiber yarn 5 and protect the fiber yarn 5.

[0045] The tension of the fiber yarn 5 is adjusted by adjusting the revolution speed of the tensioning wheel 41 and the yarn withdrawing assembly 3. The tensioning wheel 41 is arranged on the frame assembly 1 along the radial direction of the circle formed by the revolution of the yarn withdrawing assembly 3, and the tensioning wheel 41 can be located on the inner side or the outer side of the radial direction, and the radius of the circle formed by the revolution of the tensioning wheel 41 can also be the same as the radius of the circle formed by the revolution of the yarn withdrawing assembly 3. When the fiber yarn 5 is loose, the revolution speed of the tensioning wheel 41 or the yarn withdrawing assembly 3 is adjusted to increase the distance between the yarn withdrawing assembly 3 and the tensioning wheel 41, so as to tension the fiber yarn 5. When the fiber yarn 5 is too tight, the revolution speed of the tensioning wheel 41 or the yarn withdrawing assembly 3 is adjusted to reduce the distance between the yarn withdrawing assembly 3 and the tensioning wheel 41, so as to loosen the fiber yarn 5.

[0046] In some embodiments, the yarn guiding assembly 4 includes a supporting wheel 42, which is arranged along the radial direction of the circle formed by the revolution of the tensioning wheel 41. The supporting wheel 42 revolves around the winding assembly 2 with the revolving point as the center, that is, the supporting wheel 42 also revolves around the winding assembly 2, and the revolution speed of the supporting wheel 42 is the same as that of the tensioning wheel 41.

[0047] In some embodiments, the frame assembly 1 further comprises a second track 13, the second track 13 is a circle, the center of the circle of the second track 13 is on the winding shaft, and the supporting wheel 42 is arranged on the second track 13 through a second sliding block.

[0048] In one of the embodiments, the supporting wheel 42 does not rotate by itself, which simplifies the structure and improves the stability. In another embodiment, the supporting wheel 42 rotates by itself, which can reduce the wear and tear of the fiber yarn 5 and protect the fiber yarn 5.

[0049] The arrangement of the supporting wheel 42 improves the stability of the fiber yarn 5 during movement, reduces the problems of irregular winding and entanglement caused by the shaking or deviation of the fiber yarn 5, and makes the wound fiber yarn 5 more compact and uniform.

[0050] In some embodiments, the number of supporting wheels is two, and along the radial direction of the circle formed by the rotation of the tensioning wheel, one of the two supporting wheels is located on the inner side of the radial direction, and the other supporting wheel is located on the outer side of the radial direction. The fiber yarn withdrawn from the yarn withdrawing assembly passes through one of the supporting wheels, the tensioning wheel and the other supporting wheel in sequence, and is wound on the winding assembly. The rotation speed of the two supporting wheels can be adjusted according to the movement of the fiber yarn, and the rotation speed of the two supporting wheels can be the same or different.

[0051] The arrangement of the two supporting wheels can provide a more stable support system for the fiber yarn, ensuring that the fiber yarn will not shake or deviate due to insufficient support during operation.

[0052] In some embodiments, the yarn guide assembly 4 comprises a flattening wheel 43 for flattening the fiber yarn 5, the flattening wheel 43 rotates around the center of the rotation point, i.e. the flattening wheel 43 rotates around the winding assembly 2, the axis of the flattening wheel 43 is parallel to the winding shaft, and the rotation speed of the flattening wheel 43 is the same as the rotation speed of the yarn withdrawing assembly 3.

[0053] In one of the embodiments, the frame assembly 1 comprises a third track 14, the third track 14 is a circular track 11, the center of the circle of the third track 14 is on the winding shaft, and the flattening wheel 43 is arranged on the third track 14 through a third sliding block. In this embodiment, as shown in Figure 1 The frame assembly 1 comprises a circular track 11, a first track 12, a second track 13 and a third track 14, the above four tracks are arranged with the same center, along the radial direction of the circular track 11, from the inside to the outside, the third track 14, the second track 13, the first track 12 and the circular track 11 are arranged in sequence, and the third track 14 is closest to the winding assembly 2.

[0054] In one embodiment, the flattening wheel 43 does not rotate, which simplifies the structure and improves stability. In another embodiment, the flattening wheel 43 rotates, which can reduce wear on the fiber filaments 5 and protect the fiber filaments 5.

[0055] The surface of the flattening wheel 43 can be provided with a rubber layer, which can ensure the flattening effect on the fiber filaments 5 and reduce damage to the fiber filaments 5. The surface of the flattening wheel 43 can be provided with grooves or protrusions, which can further comb the fiber filaments 5 and make them more orderly while flattening the fiber filaments 5.

[0056] In some embodiments, the number of flattening wheels 43 is two, and the flattening wheels 43 have the same revolution speed, which can make the fiber filaments 5 transition smoothly between the two flattening wheels 43 and reduce bending, twisting, and the like of the fiber filaments 5. The center axes of the two flattening wheels 43 are parallel, which can make the motion trajectory of the fiber filaments 5 stable during flattening. The fiber filaments 5 adhere to the outer side wall of the flattening wheel 43 and extend to the winding assembly 2 in turn, which can ensure that the fiber filaments 5 can fully contact the flattening wheel 43 and make the flattening effect of the flattening wheel 43 effectively transmitted to the fiber filaments 5.

[0057] In some embodiments, a controller is further included, which is electrically connected to the fiber filament unwinding assembly 3 and the fiber filament guiding assembly 4. The controller is used to control the revolution speed of the fiber filament unwinding assembly 3 and the fiber filament guiding assembly 4. The controller can accurately send instructions to the fiber filament unwinding assembly 3 and the fiber filament guiding assembly 4 according to a preset program or real-time detection data, and control the revolution speed of the fiber filament unwinding assembly 3 and the fiber filament guiding assembly 4. Precise adjustment of the revolution speed of the fiber filament unwinding assembly 3 and the fiber filament guiding assembly 4 can ensure that the fiber filaments 5 are unwound at a uniform speed and avoid stretching, deformation, or breakage of the fiber filaments 5 caused by speed fluctuations.

[0058] In one embodiment, a sensor can be further provided to detect the tension of the fiber filaments 5, so that the controller can more accurately adjust the revolution speed of the fiber filament guiding assembly 4 according to the real-time tension of the fiber filaments 5.

[0059] In some embodiments, the distance between the fiber filament unwinding assembly 3 and the rotation point is a first distance, the distance between the fiber filament guiding assembly 4 and the rotation point is a second distance, the value of the second distance is greater than zero, and the second distance is less than or equal to the first distance. That is, in the radial direction of the circle formed by the revolution of the fiber filament unwinding assembly 3, the fiber filament guiding assembly 4 is located on the inner side, or the radius of the circle formed by the revolution of the fiber filament guiding assembly 4 is the same as the radius of the circle formed by the revolution of the fiber filament unwinding assembly 3. This can effectively guide the fiber filaments 5 by the fiber filament guiding assembly 4.
