[0030] like Figures 1 to 4 As shown, an economical fiber spreading structure includes: a movable fiber spreading assembly 1, a fixed fiber spreading assembly 2 and a fixed bracket 3;

[0031] The movable fiber spreading assembly 1 includes a plurality of movable fiber spreading rollers 11 and a plurality of movable brackets 12. The movable brackets 12 can be fixed at both ends of the movable fiber spreading rollers 11.

[0032] The fixed fiber spreading assembly 2 includes a plurality of fixed fiber spreading rollers 21, and the plurality of fixed fiber spreading rollers 21 are fixed on the fixed bracket 3;

[0033] The movable bracket 12 can be fixed on the fixed bracket 3 .

[0034] By designing a movable fiber spreading component 1, the fiber spreading structure can be quickly adjusted according to changes in fiber materials and processing requirements. The movable bracket 12 is fixed on the fixed bracket 3, and can adjust the distance between the movable fiber spreading roller 11 and the fixed fiber spreading roller 21 to increase its flexibility, so that the fiber spreading structure can adapt to various application scenarios and improve the versatility and utilization efficiency of the fiber spreading structure; the fixed fiber spreading roller 21 is fixed on the fixed bracket 3, which ensures the stability of the fiber spreading process and improves the processing quality and product consistency.

[0035] As a preferred embodiment of the above, U-shaped blocks 11A are provided at both ends of the movable fiber spreading roller 11, and a U-shaped bayonet 12A is provided in the middle of the movable bracket 12;

[0036] The U-shaped block 11A matches the U-shaped bayonet 12A.

[0037] The matching design of the U-shaped block 11A and the U-shaped bayonet 12A makes the connection between the movable fiber spreading roller 11 and the movable bracket 12 simple and quick. The movable fiber spreading roller 11 can be easily fixed to or removed from the movable bracket 12 without using additional tools or complicated operating steps, making the maintenance and replacement of the movable fiber spreading roller 11 more convenient and improving production efficiency. In addition, during the fiber spreading process, the movable fiber spreading roller 11 can be effectively prevented from loosening or falling off, thereby ensuring the stable transmission and processing quality of the fiber material. By adopting the U-shaped block 11A and the U-shaped bayonet 12A, the additional connectors or fasteners that may be required in the traditional connection method are reduced, thereby reducing the manufacturing cost.

[0038] In this embodiment, a plurality of first through holes 32 are provided on both outer side surfaces of the fixing bracket 3 along the horizontal direction, and both ends of the fixing fiber spreading roller 21 are disposed in the first through holes 32 .

[0039] The fixed fiber spreading roller 21 is installed by directly inserting it into the first through holes 32 on both sides of the fixed bracket 3, which greatly reduces the difficulty of installation. The design of the first through holes 32 makes the position of the fixed fiber spreading roller 21 on the fixed bracket 3 fixed and accurate. Each through hole corresponds to a specific position, ensuring that the fixed fiber spreading roller 21 can maintain a stable horizontal position and spacing after installation.

[0040] As a preferred embodiment of the above embodiment, first key slots 21A are provided at both ends of the fixed fiber spreading roller 21, and second key slots 33 are provided on both outer sides of the fixed bracket 3, and the second key slots 33 cover the plurality of first through holes 32 on the outer side.

[0041] The first key groove 21A matches the second key groove 33 , and by providing a fixed key 4 in the second key groove 33 , the fixed fiber spreading roller 21 can be completely fixed on the fixed bracket 3 .

[0042] By designing the first keyway 21A and the second keyway 33, and combining the use of the fixed key 4, the fixed fiber spreading roller 21 can be firmly fixed on the fixed bracket 3, which not only ensures the stability of the fixed fiber spreading roller 21, but also effectively reduces the shaking and displacement of the fixed fiber spreading roller 21, thereby ensuring the stable transmission and uniform spreading of the fiber material; the matching of the first keyway 21A and the second keyway 33 makes the positioning of the fixed fiber spreading roller 21 on the fixed bracket 3 more precise; by adjusting the size and shape of the keyway and the fixed key 4, different models of fixed fiber spreading rollers 21 can be adapted, thereby increasing the versatility and applicability of the fiber spreading structure.

[0043] In this embodiment, a plurality of slots 34 are provided on the inner side surface of the fixed bracket 3 along the vertical direction. The width of the slots 34 matches the width of the movable bracket 12 .

[0044] Since the slot 34 is arranged in the vertical direction, the movable bracket 12 can be connected to any position of the slot 34 as needed, so that the distance between the movable fiber spreading roller 11 and the fixed fiber spreading roller 21 can be flexibly adjusted to adapt to changes in different fiber materials and processing requirements. Whether it is necessary to increase or decrease the spacing between the fiber spreading rollers, it can be achieved by simply moving the movable bracket 12 to a different position of the slot 34; the matching design of the slot 34 and the width of the movable bracket 12 makes the installation process simple and quick, and the movable bracket 12 can be easily inserted into or removed from the slot 34, reducing installation time; the simple matching design of the slot 34 and the movable bracket 12 reduces the need for additional connectors and fixing devices, thereby reducing manufacturing costs.

[0045] In this embodiment, the movable bracket 12 can be engaged at any position of the engaging slot 34 as needed to adjust the distance between the movable fiber spreading roller 11 and the fixed fiber spreading roller 21 .

[0046] By flexibly engaging the movable bracket 12 in the slot 34, the distance between the movable fiber spreading roller 11 and the fixed fiber spreading roller 21 can be easily adjusted, so that the fiber spreading structure can adapt to changes in different fiber materials and processing requirements. Whether it is processing fibers of different thicknesses and lengths, or adjusting the tension of the fiber spreading process, it can be achieved by adjusting the roller spacing, thereby ensuring uniform fiber spreading and high-quality processing.

[0047] In this embodiment, two cross bars 31 are fixedly provided on the fixed bracket 3 , and a temperature control probe bracket 31A is fixedly provided on one cross bar 31 .

[0048] By arranging a cross bar 31 on the fixed bracket 3 and fixing the temperature control probe bracket 31A on the cross bar 31, the temperature control probe can be easily installed and positioned. The temperature control probe can monitor the temperature changes in the fiber spreading process in real time, making temperature monitoring more convenient and efficient, and improving the controllability of production; the fixed connection between the cross bar 31 and the fixed bracket 3 ensures the stability of the temperature control probe bracket 31A. During the fiber spreading process, even if it is affected by external force or vibration, the temperature control probe bracket 31A can remain stable, avoiding measurement errors caused by loosening or displacement; using the cross bar 31 on the fixed bracket 3 to install the temperature control probe bracket 31A makes full use of the space, avoids the additional support structure of the fiber spreading structure, reduces the overall volume and floor area, and improves space utilization.

[0049] In this embodiment, the surfaces of the movable fiber spreading roller 11 and the fixed fiber spreading roller 21 are both covered with anti-slip and wear-resistant materials.

[0050] The use of anti-slip and wear-resistant materials can increase the friction between the fiber spreading roller and the fiber, allowing the fiber to slide more smoothly on the roller surface, reducing slippage, helping to evenly spread the fiber, improving the fiber spreading efficiency, and ensuring the stability and continuity of the fiber material during the processing; and the anti-slip and wear-resistant material has excellent wear resistance and can effectively resist the wear of the fiber on the roller surface during the fiber spreading process, which can not only reduce the wear rate of the roller and extend its service life, but also reduce the frequency of roller replacement and reduce maintenance costs.

The above-described embodiments and the specification are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
