Description

Technical Field

[0001] The utility model belongs to the technical field of warping machines, and particularly relates to a beating device and a fiber spreading warping machine for carbon fiber spreading warping machines. Background Technique

[0002] A carbon fiber spreading warping machine is a warping machine that evenly spreads multiple bundles of untwisted filament raw materials into a sheet yarn of a certain gram weight and then winds it onto a beam head at a constant speed and constant tension.

[0003] General principle of the carbon fiber spreading warping machine: Fibers are passively unwound from the wound yarn bobbins. There are several yarn bobbins wound with carbon fiber yarns installed on the passive unwinding yarn frame. After passing through the guide tube and the yarn dividing reed, they enter the roller device, and then enter the jitter heating and fiber spreading area for high-frequency jittering and heating. After fiber spreading, they enter the pulling area, and finally are wound onto the beam head at a constant speed and constant tension.

[0004] Since the fibers are arranged orderly along the axial direction and are passively unwound from the wound yarn bobbins before arrangement, it is inevitable that the fibers are bent and not straight or uneven during unwinding.

[0005] The original ordinary guide roller has defects: During the fiber spreading process, it is inevitable that the carbon fiber distribution is uneven, the gaps between adjacent yarns are inconsistent, or the yarns are inclined disorderly and folded randomly, resulting in incomplete fiber spreading and poor fiber spreading effect, as Figure 1 shown; in addition, if manual intervention is not timely and the accumulation and removal of wool yarn scraps are not timely, the yarns will stick together. The above phenomena have a great impact on the quality of fiber spreading on the beam head. At present, the above problems need to be solved by timely manual intervention and manual processing, which wastes labor, has low warping efficiency and unstable quality. Content of the Utility Model

[0016] Further, the guiding device is a guiding roller.

[0036] The present utility model will now be described in further detail with reference to the 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 embodiments are not adopted in a restrictive sense, and the scope of the claimed subject matter is only defined by the appended claims and their equivalents.

[0037] As Figure 2 and Figure 3 shown, a beating device of a carbon fiber spreading warping machine is arranged between a yarn rack 2 and a winding bobbin 8 of the spreading warping machine and is used for beating the yarn 10 unwound from the yarn rack 2 to make the fiber spreading uniform. The beating device 1 includes a centrally rotating roller body 101, and at least one boss 102 is formed on the outer peripheral wall of the roller body 101 protruding radially. The boss 102 can be fixedly connected or detachably connected to the roller body 101. The detachable connection method includes but is not limited to snap connection, etc. Each boss 102 extends along the axial direction of the roller body 101. A guiding surface 1011 for guiding the yarn 10 is formed on the outer peripheral wall of the roller body 101, and a beating surface 1021 for beating the yarn 10 is formed on the outer peripheral wall of the boss 102. The beating surface 1021 protrudes from the guiding surface 1011 to form an eccentric structure. Each time the roller body 101 rotates one circle, each boss 102 can beat the passing yarn 10 once. Therefore, the number of bosses 102 can be but is not limited to one, two, three, etc. This embodiment does not limit this, and the number of bosses 102 can be set according to the actual required beating frequency, such as Figure 3 shown in FIGS. 3a and 3b.

[0038] During the rotation of the roller body 101, the boss 102 is driven to rotate synchronously. When the guiding surface 1011 contacts the yarn 10, the guiding surface 1011 can guide the yarn 10. When the beating surface 1021 contacts the yarn 10, the protruding beating surface 1021 can beat the yarn 10 to make the yarn 10 always evenly distributed in the axial direction, as Figure 5 shown.

[0039] In some examples, the beating surface 1021 is an arc structure, and the diameter of the beating surface 1021 is much smaller than that of the guiding surface 1011, so as to slightly beat the yarn 10 during the running of the yarn 10, with a small beating amplitude, and avoid breaking the yarn 10 during the beating process.

[0040] In some examples, a groove 1022 is formed inside the boss 102. The groove 1022 extends along the axial direction of the boss 102 to form a hollow boss 102. The hollow boss 102 can reduce its own weight, thereby reducing the overall weight of the beating device 1. Of course, the boss 102 can also be a solid structure to improve its own structural strength.

[0041] In some examples, the axial extension length of the boss 102 is the same as that of the roller body 101, so that the boss 102 can beat all the yarns 10 arranged along the axial direction of the roller body 101.

[0042] In some examples, there are two bosses 102, and the two bosses 102 are symmetrically distributed along the axis of the central roller 101. That is, during the rotation of the central roller 101, it evenly pats the passing yarn twice for each rotation, as Figure 3 shown in Fig. b.

[0043] In some examples, the beating device 1 further includes a base 103, a motor 104 installed on the base 103, a mandrel 105 inserted into the central roller 101, and a coupling 106 for connecting the output shaft of the motor 104 and the mandrel 105. A bearing 107 is installed between the mandrel 105 and the base 103. The motor 104 is installed on the base 103 through a motor base, and the motor 104 is directly connected to a speed reducer and connected to the mandrel 105 of the central roller 101 through the coupling 106 to drive the central roller 101 to rotate continuously.

[0044] In some examples, a fiber spreading warping machine includes the above-mentioned beating device 1, and further includes a yarn rack 2, a guiding tube 3, a yarn dividing reed 4, a roller device 5, a fiber spreading device 6, a drawing device 7, and a winding bobbin 8 that are sequentially distributed along the fiber spreading path of the yarn 10. A plurality of yarn bobbins 201 wound with carbon fiber yarns 10 are installed on the yarn rack 2. The beating device 1 is arranged between the fiber spreading device 6 and the drawing device 7. After the yarn 10 is unwound from the wound yarn bobbin 201, it enters the roller device 5 through the guiding tube 3 and the yarn dividing reed 4, then enters the fiber spreading device 6 for high-frequency jittering and heating to achieve fiber spreading, and then enters the drawing device 7, and finally is wound on the winding bobbin 8.

[0045] In some examples, the fiber spreading device 6 includes a jittering unit for performing high-frequency jittering on the yarn 10 and a heating unit for heating the yarn 10. The jittering unit includes a plurality of jittering rollers 601 arranged at intervals, and the heating unit includes a plurality of heating rollers 602 arranged at intervals. The jittering unit and the heating unit are distributed on both sides of the yarn 10, and the jittering rollers 601 and the heating rollers 602 are arranged at intervals so that jittering and heating are performed alternately.

[0046] In some examples, guiding devices 9 for guiding the yarn 10 are provided between adjacent ones of the yarn dividing reed 4, the roller device 5, the fiber spreading device 6, the drawing device 7, and the winding bobbin 8 to improve the stability of the yarn 10 during operation. The guiding device 9 can be a guiding roller.

[0047] Based on the ideal embodiments of the present invention as inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
