[0002] As described in the published patent CN119502414A, "A carbon fiber impregnation device", "In the process of carbon fiber from carbon fiber to fiber prepreg to carbon fiber prepreg, it needs to go through steps such as yarn feeding, yarn spreading, impregnation and pressing, and some also include processes such as film coating, edge trimming and winding".

[0003] The support frame 100 is connected to a shaft seat that mates with the shaft. The shaft seat consists of two elastic clamping plates, with an adjustable shaft hole between the two plates that mates with the shaft. The two elastic clamping plates are connected by a clamping adjustment bolt. One of the elastic clamping plates b has a connecting hole that mates with the clamping adjustment bolt, and the other elastic clamping plate a has a screw hole that mates with the clamping adjustment bolt. By tightening / loosening the clamping adjustment bolt, the shaft seat can clamp and release the shaft, thereby allowing the angle of the tensioning column on the shaft to be adjusted (paragraph 0057 of the instruction manual).

Based on the above, the applicant found through actual use that the tensioning column can only rotate circumferentially, and the angle adjustment effect is limited. Moreover, the tensioning column cannot be adjusted in height, thus limiting its applicability in actual processing. Utility Model Content

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-7 An adjustable carbon fiber wrinkle-reducing mechanism includes a support frame 100, a lifting adjustment component 101 on the support frame 100, and a shaping component 102 on the lifting adjustment component 101. The lifting adjustment assembly 101 includes an upper mounting plate 103 and a lower mounting plate 104 respectively fixedly mounted on the upper and lower ends of the support frame 100. A guide rail 105 is fixedly mounted between the upper mounting plate 103 and the lower mounting plate 104, and a threaded adjustment rod 106 is rotatably mounted between the upper mounting plate 103 and the lower mounting plate 104. A slider 107 is slidably mounted on the guide rail 105. The slider 107 is screwed into the threaded adjusting rod 106. A motor 108 that drives the threaded adjusting rod 106 to rotate is mounted on the lower mounting plate 104. The shaping component 102 includes a shaping support plate 109 fixedly mounted on the slider 107, and a first side plate 110 is formed on the shaping support plate 109. A first adjusting rod 111 and a second adjusting rod 112 are rotatably connected to the first side plate 110, and the lower ends of the first adjusting rod 111 and the second adjusting rod 112 are engaged in transmission. The upper ends of the first adjusting rod 111 and the second adjusting rod 112 are respectively rotatably connected to the third adjusting rod 113 and the fourth adjusting rod 114. The upper ends of the third adjusting rod 113 and the fourth adjusting rod 114 are rotatably connected to the second side plate 115. The upper ends of the third adjusting rod 113 and the fourth adjusting rod 114 are engaged in transmission. A telescopic adjustment assembly 116 is installed between the first adjusting rod 111 and the second adjusting rod 112. The telescopic adjustment assembly 116 is used to adjust the deflection of the first adjusting rod 111 and the second adjusting rod 112. The vertical height of the shaping component 102 is adjusted by the lifting adjustment component 101, which allows for the application of longitudinal tension forces at different positions to carbon fiber fabrics or prepregs of different thicknesses and layers. At the same time, the pitch angle of the third adjustment rod 113 and the fourth adjustment rod 114 can be controlled by the linkage-meshing transmission system driven by the telescopic adjustment component 116 inside the shaping component 102. This combined height and angle adjustment capability allows the mechanism to flexibly adjust the position and posture of its tensioning working end in three-dimensional space from a fixed support point, achieving precise control of the tension force vector of the carbon fiber material. Because it can make precise adjustments in multiple dimensions, this mechanism can handle various wrinkle patterns that occur in carbon fiber during the unwinding, spreading and impregnation process. Whether it is a slight wave caused by uneven local tension or a deep wrinkle caused by a blocked path, the operator can use the method of "first raising and lowering for positioning, then adjusting the angle for alignment" to allow the tensioning mechanism to intervene in the appropriate posture and evenly spread the fiber. This targeted wrinkle reduction capability can effectively eliminate internal stress concentration and reduce the risk of defects such as dry yarn, white thread or uneven resin distribution in carbon fiber prepreg. Its wide lifting stroke enables it to adapt to the requirements of various carbon fiber product production lines, from thin to thick layers. At the same time, its flexible angle adjustment function allows it to not only handle straight fiber bundles, but also better adapt to layup processes with certain curvature or special orientation. This means that the same anti-wrinkle mechanism can be applied to more diverse production scenarios and product types. In the shaping assembly 102, the first and second adjusting rods 112 and the third and fourth adjusting rods 114 are engaged by meshing transmission. This design ensures that when the telescopic adjusting assembly 116 is activated, the movement of the connecting rods on both sides is synchronous and symmetrical, reducing the material deviation, lateral slippage or new asymmetrical wrinkles that may be caused by unilateral adjustment, and ensuring that the tension force always acts on the centerline of the material. This invention's wrinkle reduction mechanism achieves wrinkle reduction through the synergistic action of the lifting adjustment component 101 and the shaping component 102. The motor component 108 drives the threaded adjusting rod 106 to rotate, causing the slider component 107 to slide up and down along the guide rail component 105, thereby adjusting the height of the shaping component 102 and achieving longitudinal tension adjustment. Through meshing transmission, the first adjusting rod 111 and the second adjusting rod 112 are driven to deflect synchronously, thereby adjusting the angles of the third adjusting rod 113 and the fourth adjusting rod 114, achieving multi-directional tension control. This overcomes the limitations of related technologies where the tensioning column can only rotate circumferentially and cannot be raised or lowered. Through flexible adjustment of height and angle, it effectively adapts to the processing needs of different carbon fiber materials.

[0018] In this embodiment of the present invention, the upper end of the first adjusting rod 111 is rotatably mounted with a first adjusting shaft 117, the upper end of the second adjusting rod 112 is rotatably mounted with a second adjusting shaft 118, the third adjusting rod 113 is rotatably connected to the first adjusting shaft 117, and the fourth adjusting rod 114 is rotatably connected to the second adjusting shaft 118. The telescopic adjustment assembly 116 includes a first screw seat 119 and a second screw seat 120 respectively fixedly mounted on a first adjustment shaft 117 and a second adjustment shaft 118. A screw rod 121 is installed between the first screw seat 119 and the second screw seat 120. A knob 122 is fixedly mounted on the screw rod 121. The knob 122 divides the screw rod 121 into a left screw portion 123 and a right screw portion 124. The thread directions of the left screw portion 123 and the right screw portion 124 are opposite. The coordination logic of the first, second, third and fourth adjusting rods 114 is referenced to the published patent "A Scissor Jack" with publication number CN217264509U; The screw rod 121 in the telescopic adjustment assembly 116 has a left screw part 123 and a right screw part 124 with opposite thread directions. When the operator rotates the knob 122, it will force the first screw seat 119 and the second screw seat 120 to move towards or away from each other at the same distance. This ensures that the deflection angles of the first adjustment rod 111 and the second adjustment rod 112 connected to the first and second adjustment shafts 118 remain symmetrical, eliminating the risk of cumulative errors or asynchronous movement that may occur due to adjusting the two sides separately. The second side plate 115 at the top always changes in height without unnecessary lateral drift. This is crucial for maintaining the centering of the carbon fiber bundle during the tensioning process and avoiding new wrinkles caused by unilateral force. Operators do not need to use tools or perform complex double-sided calibrations. They can adjust the entire angle adjustment mechanism simultaneously by simply turning a knob. There is a corresponding relationship between the rotation of the screw rod 121 and the linear displacement of the first screw seat 119 and the second screw seat 120. This makes the angle adjustment controllable. After the adjustment is in place, the angle structure of the entire shaping component 102 will be firmly locked without actively rotating the knob. It will not creep or retract due to the continuous tension of the carbon fiber material. By rotating a single knob 122, the screw rods 121 with opposite thread directions on both sides are driven, causing the first screw seat 119 and the second screw seat 120 to move synchronously towards or away from each other on the screw rod 121. This precisely controls the distance between the first adjusting shaft 117 and the second adjusting shaft 118, which in turn causes the first adjusting rod 111 and the second adjusting rod 112 connected to them to deflect symmetrically and equally, and in turn causes the third adjusting rod 113 and the fourth adjusting rod 114 to deflect symmetrically and equally. This achieves the synchronicity and ease of operation of the tensioning mechanism angle adjustment. A single operation can ensure the symmetrical movement of the two adjusting rods, effectively preventing the carbon fiber material from deviating or developing new wrinkles due to asynchronous adjustment.

[0019] In this embodiment of the utility model, a first mounting shaft 125 and a second mounting shaft 126 are rotatably mounted on the first side plate 110, and the lower ends of the first adjusting rod 111 and the second adjusting rod 112 are respectively rotatably mounted on the first mounting shaft 125 and the second mounting shaft 126. The second side plate 115 is rotatably mounted with a third mounting shaft 127 and a fourth mounting shaft 128, and the upper ends of the third adjusting rod 113 and the fourth adjusting rod 114 are respectively rotatably mounted on the third mounting shaft 127 and the fourth mounting shaft 128. By setting the first and second mounting shafts 126 on the first side plate 110 and the third and fourth mounting shafts 128 on the second side plate 115, stable and independent rotation fulcrums are provided for the lower ends of the first and second adjusting rods 112 and the upper ends of the third and fourth adjusting rods 114, thus constructing a robust pivot frame. This allows each adjusting rod to rotate smoothly around its respective mounting shaft, thereby efficiently and reliably converting the linear driving force generated by the telescopic adjusting assembly 116 into the overall angular deflection of the shaping assembly 102. By distributing the force points and ensuring the alignment of the rotation axis, the structural rigidity and motion smoothness of the entire linkage transmission system are significantly enhanced.

[0020] In this embodiment of the utility model, an arc-shaped transition piece 129 is installed at the upper end of the second side plate 115; The arc-shaped transition piece 129 serves as the direct contact and tensioning end of the carbon fiber material. Its smooth and continuous curved surface replaces the sharp edges of the third adjusting rod 113 and the fourth adjusting rod 114, allowing the carbon fiber material to achieve a smooth and impact-free arc transition at the contact point when passing through this component. This significantly reduces the frictional resistance and local stress concentration of the carbon fiber bundle or prepreg during the tensioning adjustment process, and effectively prevents fiber damage, fuzzing, or breakage caused by sharp edges.

[0021] In this embodiment of the utility model, the ends of the third adjusting rod 113 and the fourth adjusting rod 114 that are opposite to each other are respectively equipped with an extension transition member 130; By adding arc-shaped transition pieces 129 to the opposite ends of the third adjusting rod 113 and the fourth adjusting rod 114, an additional, dynamic, smooth contact interface is provided for the carbon fiber material when it passes through the complex multi-link adjusting mechanism. This effectively eliminates the side scratches, hooks, or cuts that the ends of the third adjusting rod 113 and the fourth adjusting rod 114 may cause to the carbon fiber material. Together with the arc-shaped transition piece 129 at the upper end of the second side plate 115, it forms an all-round flexible protection system.

[0022] In this embodiment of the present invention, the upper end surfaces of the third adjusting rod 113 and the fourth adjusting rod 114 are respectively equipped with side baffles 131; By installing side baffles 131 on the upper end faces of the third adjusting rod 113 and the fourth adjusting rod 114, the carbon fiber material conveyed in the area above the third adjusting rod 113 and the fourth adjusting rod 114 is provided with physical lateral restraint, which effectively prevents the carbon fiber bundle from shifting to the left or right, slipping or tangling with adjacent bundles due to tension fluctuations or equipment vibration during tensioning and transmission. This ensures that the material always travels smoothly along the predetermined path, maintaining a uniform tension distribution and neat arrangement.

[0023] In this embodiment of the utility model, a mounting hole 132 is provided on the lower mounting plate 104, and the motor component 108 is fixedly mounted on the lower end surface of the lower mounting plate 104. The output shaft of the motor component 108 passes through the mounting hole 132 upward and is fixedly connected to the threaded adjusting rod 106. The motor component 108 is installed below the lower mounting plate 104, so that its output axis passes through the mounting hole 132 and is directly fixedly connected to the threaded adjusting rod 106. Thus, the motor component 108 drives the threaded adjusting rod 106 to rotate stably at its axial position. This makes full use of the longitudinal space at the bottom of the support frame 100, realizes the compactness of the equipment structure and the reduction of the overall center of gravity, and enhances the stability of the mechanism during operation. At the same time, this layout effectively isolates the motor component 108 from the working area above, reducing the risk of carbon fiber debris or resin contamination to the motor.

[0024] In this embodiment of the utility model, the upper end surface of the lower end mounting plate 104 and the lower end surface of the upper end mounting plate 103 are respectively provided with limit mounting holes 134132, and limit switches 135 are installed in the limit mounting holes 134132. By setting a limit switch 135 on the upper surface of the lower mounting plate 104, the limit switch 135 and the slider 107 that moves up and down in the lifting adjustment assembly 101 form a position sensing cooperation. When the slider 107 moves to the preset lower limit (or upper limit) position during the lifting process, the limit switch 135 will be triggered, thereby automatically sending a signal to the control system and cutting off the power of the motor 108 or stopping its operation. This effectively prevents the slider 107 from being damaged by overload or even jammed due to control errors or circuit failures hitting the lower mounting plate 104 (or the upper mounting plate 103), thus improving the safety and reliability of the equipment operation.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
