[0033] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner. Therefore, they only show the components related to the present utility model. Directions and references (such as up, down, left, right, etc.) can only be used to assist in the description of the features in the drawings. Therefore, the following detailed implementation manners are not adopted in a restrictive sense, and the scope of the claimed subject matter is only defined by the appended claims and their equivalent forms.
[0034] As Figures 1 - 3 shown, a yarn guiding rod of a carbon fiber fiber spreading yarn holder is arranged between the yarn holder 3 of the fiber spreading warping machine and the fiber spreading device. A plurality of bobbins 2 are installed on the yarn holder 3. The plurality of bobbins 2 correspond to a plurality of yarn guiding rods 1 one by one, and each yarn guiding rod 1 is used to guide the yarn unwound from the corresponding bobbin 2. The yarn guiding rod 1 includes a rod body. The middle part of the rod body is bent away from the bobbin 2 so that an arc-shaped concave wire routing area 101 is formed on the side of the rod body close to the bobbin 2. The wire routing area 101 is a centrosymmetric structure. The wire routing area 101 divides the rod body into a first limiting part 102 at one end and a second limiting part 103 at the other end. The wire routing area 101 is located between the first limiting part 102 and the second limiting part 103. The first limiting part 102 and the second limiting part 103 are at the same height and are horizontal. The yarn guiding rod 1 is fixed on the yarn holder 1 through the first limiting part 102 or the second limiting part 103. When the yarn is unwound from the bobbin 2, the concave wire routing area 101 can control the yarn within a preset interval, effectively controlling the direction of the yarn, preventing it from slipping out, and adjusting the yarn tension.
[0035] In some examples, the extension length of the wire routing area 101 is greater than the axial extension length of the corresponding bobbin 2, that is, both ends of the wire routing area 101 extend beyond the bobbin 2, so as to prevent the yarn unwound from the bobbin 2 from slipping.
[0036] In some examples, the center line of the routing area 101 is the first center line A1, the center line of the yarn drum 2 is the second center line A2, and the first center line A1 of the routing area 101 and the second center line A2 of the corresponding yarn drum 2 are collinear to ensure that the yarn unwound from the yarn drum 2 can all enter the routing area 101 and be arranged in an orderly manner.
[0037] In some examples, the distance H between the routing area 101 and the first limiting portion 102 does not exceed 50 mm.
[0038] In some examples, the radial cross-section of the yarn guide rod 1 is circular to prevent the yarn from breaking due to the contact between the angular yarn guide rod 1 and the yarn.
[0039] In some examples, a fiber spreading warping machine includes the above-mentioned carbon fiber spreading yarn frame guide rod, and also includes a yarn frame 3, on which a plurality of yarn tubes 2 and a rotary drive mechanism 4 are installed. The plurality of rotary drive mechanisms 4 correspond one-to-one to the plurality of yarn tubes 2, and each rotary drive mechanism 4 is used to drive the corresponding yarn tube 2 to rotate to realize the unwinding of the yarn on the yarn tube 2 and keep the tension of the unwound yarn.
[0040] In some examples, the rotary drive mechanism 4 is a magnetic powder brake. Currently, most domestic carbon fiber spreading creels are passive creels. Even those that use active creels typically use torque motors. Torque motors typically utilize torque controllers, which require on-site voltage adjustment to control output torque in order to maintain constant yarn tension. This approach is only suitable for tension control with a single motor, while a single yarn unwinding creel may require at least dozens, or as many as one or two hundred, torque motors and their corresponding control systems, significantly increasing implementation costs. If motor control systems were grouped, each motor would have different characteristics and could not be individually adjusted. This embodiment utilizes a low-cost, small magnetic powder brake instead of a torque motor. Each bobbin 2 can be individually controlled, and by adjusting the voltage, different torque values can be achieved. During this process, feedback data can be generated based on the bobbin 2 diameter to continuously control its output constant tension in real time. The yarn on the bobbin 2 is collected and transferred to the fiber spreading device via a yarn guide. When the machine stops, the output torque can be increased, achieving a reliable stop. Furthermore, the embodiment has the advantages of fast response, simple structure, no pollution, and no noise.
[0041] In some examples, the yarn bobbins 2 are arranged in multiple rows along the longitudinal direction, and at least one yarn guide plate 5 is installed at the position of each row of yarn bobbins 2 on the yarn rack 3. The yarn guide plate 5 is provided with a yarn guide hole 501 for the yarn unwound from the row of yarn bobbins 2 to pass through, and the yarn guide plate 5 is located between the yarn guide rod 1 and the fiber spreading device. The yarn unwound from the yarn bobbin 2 passes through the routing area 101 of the yarn guide rod 1 and the yarn guide hole 501 of the yarn guide plate 5 in turn and enters the fiber spreading device.
[0042] In some examples, the rotary drive mechanism 4 is mounted on the yarn rack 3 through a mounting base 6. A yarn bobbin holder 7 is arranged inside the yarn bobbin 2. A connecting seat 8 is arranged between the output end of the rotary drive mechanism 4 and the yarn bobbin holder 7. A clamping groove for the yarn bobbin holder 7 to be inserted into is formed at one end of the connecting seat 8 close to the yarn bobbin holder 7. After the yarn bobbin holder 7 is inserted into the clamping groove, the connecting seat 8 and the yarn bobbin holder 7 are locked by bolts.
[0043] In some examples, rollers 9 are mounted at the bottom of the yarn rack 3. The position of the yarn rack 3 can be conveniently adjusted through the rollers 9, and a locking mechanism for locking the rollers 9 is mounted on the rollers 9.
[0044] Based on the inspiration of the ideal embodiments of the present invention, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of the present invention. The technical scope of the present invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
