It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the drawings, not all of them.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] In the description of the embodiments disclosed herein, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings, and are used only for ease of description and simplification of operation. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are merely used for distinction in description and have no special meaning. In one embodiment, this utility model provides a prepreg rack, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, Figure 1 The left and right directions in the middle correspond to the first direction, and the up and down directions correspond to the second direction. The prepreg rack includes a support frame 1 and a fixed shaft 2 detachably mounted on the support frame 1. The fixed shaft 2 is arranged along the first direction and is used to mount a feeding roller. The feeding roller is used to release fibers or fabrics.

[0034] A set of fixing components 3 is provided at both ends of the fixed shaft 2 to fix the feeding roller;

[0035] At least one set of the fixing components 3 is slidably disposed on the fixing shaft 2 to adjust the distance between the two sets of fixing components 3.

[0036] One embodiment of this disclosure provides a prepreg rack that, by providing a slidable fixing component on a fixed shaft, allows for adjustment of the prepreg rack to accommodate prepregs of different widths. This reduces the large floor space required due to the need for multiple prepreg racks of different sizes for prepregs of varying widths. Furthermore, this prepreg rack facilitates the retrieval of prepregs of different lengths.

[0037] In one embodiment, the prepreg rack provided in this embodiment can be used for prepreg lamination technology. By adjusting at least one set of fixing components 3 to adjust the distance between them, prepregs of different widths can be adapted, so that the preparation of prepregs of different widths can be completed using a single device.

[0038] In one embodiment, each set of fixing components 3 includes a baffle 31 and a fixing member 32, with the baffle 31 located near the feeding roller. The baffle 31 can limit the two ends of the feeding roller, and the fixing member can fix it in place. Therefore, by cooperating with the two sets of fixing components, the distance between the fixing components 3 can be adjusted as needed according to the width of the feeding roller, thereby adapting to the preparation of prepregs of different widths.

[0039] In one embodiment, the projection of the baffle 31 onto the fixed shaft 2 extends 15mm-20mm beyond the edge of the fixed shaft 2. If the distance beyond the edge is too small, the baffle may enter the hollow shaft of the feeding roller and fail to provide proper positioning; if the distance beyond the edge is too large, the released fibers or fabric may be squeezed during the rotation of the feeding roller.

[0040] In one embodiment, the fixed shaft 2 is a fully threaded bearing, with the threads on both sides of the fully threaded bearing having opposite directions starting from the center position of the fixed shaft 2; the fixing member 32 is a nut, which is tightened along the direction close to the feeding roller. In one embodiment, because the fixed shaft 2 is a fully threaded bearing, the fixing components 3 on both sides of the feeding shaft can slide inward toward the feeding shaft, so that the feeding shaft is located in the middle position of the fixed shaft 2, making the structure more stable and helping to ensure the consistency of prepreg preparation. Moreover, because the fixing member 32 is a nut and the fixed shaft 2 is a fully threaded bearing, the sliding of the fixing components is easier and the fixing member 32 has good fixation.

[0041] In one embodiment, the support frame 1 includes a first support member 11 and a second support member 12 arranged at intervals along a first direction;

[0042] A third support 13 is provided between the first support 11 and the second support 12. The third support 13 is arranged along the second direction with the first support 11 and the second support, and the third support 13 is connected to the first support 11 and the second support 12.

[0043] The support frame 1 also includes a fourth support member 14, which is connected to the first support member 11, the second support member 12, and the third support member 13 respectively.

[0044] One embodiment of this disclosure constructs a support frame 1 using a first support member 11, a second support member 12, a third support member 13, and a fourth support member 14. These four support members are connected in a detachable manner or are integrally formed, and those skilled in the art can choose according to their needs.

[0045] In one embodiment, the first support member 11 includes a first frame and a first reinforcing member 111 connected to the first frame. The first reinforcing member 111 is parallel to the second direction, and a first U-shaped groove 4 is provided above the connection position of the first reinforcing member 111 and the first frame. The second support member 12 includes a second frame and a second reinforcing member 121 connected to the second frame. The second reinforcing member 121 is parallel to the second direction, and a second U-shaped groove 5 is provided above the connection position of the second reinforcing member 121 and the second frame. The first U-shaped groove 4 and the second U-shaped groove 5 are used for detachable connection with the fixed shaft 2.

[0046] In one embodiment, the first frame, the second frame, the third frame, and the fourth frame are all rectangular frames formed by connecting rods, wherein the rectangle can be either a square or a rectangle.

[0047] One embodiment of this disclosure provides a first reinforcing member 111, a second reinforcing member 121, a first U-shaped groove 4, and a second U-shaped groove 5 in the manner described above. This approach helps to reduce the mass and complexity of the frame and better ensures the stability of the support shaft 2 on the support frame 1.

[0048] In one embodiment, the third support member 13 includes a third frame and a third reinforcing member 131 connected to the third frame, the third reinforcing member 131 being parallel to the second direction; the fourth support member 14 includes a fourth frame and a cross-shaped fourth reinforcing member 141 connected to the fourth frame, the fourth reinforcing member 141 being connected to the first reinforcing member 111, the second reinforcing member 121 and the third reinforcing member 131 respectively.

[0049] By setting the third reinforcing member 131 and the fourth reinforcing member 141, the structural stability of the support frame 1 can be further improved.

[0050] In one embodiment, the support frame 1 is further provided with a material-laying rod 6. The material-laying rod 6 is arranged parallel to the first direction and is connected to the first support member 11 and the second support member 12 respectively. The material-laying rod 6 is parallel to the plane of the third support member 13 and does not contact it. The height of the material-laying rod 6 from the ground is a, and the height of the fixed shaft 2 from the ground is b. <b。

[0051] By setting up the feeding rod 6, the free end of the fiber or fabric released by the feeding roller can be placed on the feeding rod 6 to prevent the fiber or fabric from touching the ground and getting contaminated.

[0052] In one implementation, a is 350mm-550mm.

[0053] If this height value is too small, it may not be able to effectively prevent fibers or fabrics from hitting the ground; if this height value is too large, it may be detrimental to the rotation of the feed roller and the impregnation process.

[0054] In one embodiment, the plane formed by the connection of the material support rod 6 with the first support member 11 and the second support member 12 is a first plane, and a corner reinforcement member 7 is provided in the first plane, the corner reinforcement member 7 being connected to the adjacent side in the first plane.

[0055] By setting the corner reinforcement 7, the structural stability of the support frame 1 can be improved.

[0056] The dimensions of the support frame 1 are not specifically limited in this embodiment, and those skilled in the art can adjust them according to the size requirements of the prepreg.

[0057] In one embodiment, the distance between the two baffles 31 is m1, where m1 = 1100 mm. This distance also represents the distance between the fixing components 3. In another embodiment, this distance can be reduced as needed for prepregs with narrower widths, thereby achieving the purpose of adapting to prepregs of different widths.

[0058] In one embodiment, the total length of the fixed shaft 2 is m2, where m2 = 1000mm-1500mm, and can be, for example, 1000mm, 1050mm, 1100mm, 1150mm, 1200mm, 1250mm, 1300mm, 1350mm, 1400mm, or 1500mm, etc.

[0059] In one implementation, m2 = 1277 mm.

[0060] In one embodiment, the frame (i.e., the first frame and the second frame) arranged along the left-right direction (i.e. the first direction) is square in shape with a side length of n, n = 700mm-1000mm, for example, it can be 700mm, 750mm, 800mm, 850mm, 900mm, 950mm or 1000mm, etc.

[0061] In one implementation, n = 800 mm.

[0062] In one implementation, see Figure 3 The height 'a' of the support pole from the ground is 450mm.

[0063] In one embodiment, the frame (i.e., the fourth frame) arranged along the vertical direction (i.e., the second direction) is rectangular in shape, with a length of p1, where p1 = 1000mm-1500mm, for example, it can be 1000mm, 1050mm, 1100mm, 1150mm, 1200mm, 1250mm, 1300mm, 1350mm, 1400mm, or 1500mm, etc., and a width of p2, where p2 = 700mm-1000mm, for example, it can be 700mm, 750mm, 800mm, 850mm, 900mm, 950mm, or 1000mm, etc.

[0064] In one implementation, p1 = 1277 mm and p2 = 800 mm.

[0065] It should be noted that the above examples of the dimensions of the various parts of the support frame 1 are merely illustrative and are not intended to limit the present invention.

[0066] In summary, the prepreg rack provided in one embodiment of this disclosure, by providing a slidable fixing component on a fixed shaft, can be adjusted to accommodate prepregs of different widths, thereby reducing the large floor space required due to the need for multiple prepreg racks of different sizes for prepregs of different widths. Furthermore, this prepreg rack facilitates the retrieval of prepregs of different lengths.

[0067] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
