Description

Technical Field

[0001] This utility model belongs to the field of fiber processing technology. Specifically, this utility model relates to a non-woven fabric winding surface flatness adjustment device. Background Technology

[0002] As a core material in modern personal protective equipment (PPE), the performance and quality of ballistic nonwoven fabric directly affect the overall effectiveness of the equipment. With technological advancements and increasing protection demands, ballistic materials have undergone a transformation from traditional materials to high-performance materials. Traditional ballistic materials, such as aramid and carbon fiber, while exhibiting certain advantages in ballistic performance, suffer from inherent drawbacks, such as high density and high price, which limit their widespread application and further development.

[0003] To address these issues, ultra-high molecular weight polyethylene (UHMWPE) fiber was developed. This new fiber, with its lightweight, high strength, and high modulus properties, has shown great potential in the field of bulletproof materials. Compared to traditional bulletproof materials, UHMWPE fiber not only significantly reduces material weight but also substantially improves bulletproof performance, making it an ideal choice for bulletproof non-woven fabrics.

[0004] However, the high modulus and rigidity of UHMWPE fibers also present new challenges. UHMWPE fibers are one of the main raw materials for UD fabric (non-woven fabric). During the production of UD fabric, the high modulus of the fibers makes the fabric surface less prone to deformation under force. This means that slight errors in equipment traction, position level control, and unwinding tension control can easily lead to inconsistent fabric tension. Especially during the winding process, unevenness in the fabric surface can easily cause creases, which not only reduces product quality but also severely affects its appearance, thus reducing its market competitiveness.

[0005] For example, Chinese Patent Application No. 202222969329.1 discloses a polyethylene nonwoven fabric winding device, belonging to the field of nonwoven fabric manufacturing technology. The key technical points of the device include a base plate. The polyethylene nonwoven fabric winding device is equipped with a base plate, a winding mechanism, an auxiliary tensioning mechanism, a tensioning and winding component, and a flattening component. The winding mechanism winds up the nonwoven fabric. The vertical winding method allows the dust attached to the nonwoven fabric to be shaken off during winding. The auxiliary tensioning mechanism can help tighten the nonwoven fabric during winding to prevent the gap from widening and to prevent dirt from getting inside the outer nonwoven fabric roll. The tensioning and winding component straightens the nonwoven fabric to be wound during winding to prevent wrinkles and affect the use effect of the nonwoven fabric.

[0006] The aim is to provide a non-woven fabric roll-up flatness adjustment device, specifically regarding how to effectively adjust the flatness of the non-woven fabric surface before roll-up to effectively eliminate creases. Utility Model Content

[0007] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention provides a non-woven fabric roll-up flatness adjustment device, the purpose of which is to effectively adjust the flatness of the non-woven fabric surface before roll-up and effectively eliminate creases.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a non-woven fabric winding fabric surface flatness adjustment device, including a knob mounting plate, a fixing mechanism, a self-lubricating guide component disposed on the fixing mechanism and used to provide support for the non-woven fabric, and an adjustment knob that is threadedly connected to the knob mounting plate and used to adjust the height of the fixing mechanism. The adjustment knob is in contact with the fixing mechanism, and the surface of the self-lubricating guide component is provided with twill micro-protrusions that guide the non-woven fabric to spread out to both ends.

[0009] The self-lubricating guide fabric component has an arc-shaped structure, and the surface of the self-lubricating guide fabric component is an arc surface.

[0010] The self-lubricating guide cloth is made of self-lubricating resin material.

[0011] The materials of the self-lubricating guide fabric include, but are not limited to, nylon, polytetrafluoroethylene, polyoxymethylene, and polyetheretherketone.

[0012] The non-woven fabric winding flatness adjustment device also includes a fixing rod. The fixing mechanism is provided with a groove through which the fixing rod passes. At least two fixing rods are provided, and all fixing rods are arranged sequentially along the length of the groove.

[0013] The non-woven fabric winding surface flatness adjustment device also includes a stop bar, which is set on the fixed bar, and the fixing mechanism is located between the two stop bars.

[0014] The non-woven fabric winding fabric surface flatness adjustment device also includes a gantry frame, and the fixing rod and the knob mounting plate are set on the gantry frame, with the fixing rod located above the knob mounting plate.

[0015] The surface of the self-lubricating guide fabric is provided with two micro-protrusion areas. The twill micro-protrusions in the two micro-protrusion areas are symmetrically arranged, and the twill micro-protrusions in the micro-protrusion areas extend obliquely in the same direction.

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of this utility model, and to facilitate its implementation.

[0023] like Figures 1 to 3 As shown, this utility model provides a non-woven fabric winding surface flatness adjustment device for the non-woven fabric prepreg winding process. It includes a knob mounting plate 6, a fixing mechanism 3, a self-lubricating guide 2 set on the fixing mechanism 3 for providing support for the non-woven fabric, and an adjustment knob 5 that is threadedly connected to the knob mounting plate 6 for adjusting the height of the fixing mechanism 3. The adjustment knob 5 is in contact with the fixing mechanism 3. The surface of the self-lubricating guide 2 is provided with twill micro-protrusions 11 that guide the non-woven fabric to spread out to both ends.

[0024] Specifically, such as Figure 1 and Figure 3 As shown, the self-lubricating guide fabric component 2 has an arc-shaped structure. Its surface is also arc-shaped. The component is horizontally positioned with its axis horizontal. The surface of the self-lubricating guide fabric component 2 contacts the non-woven fabric, and it is located below the non-woven fabric. The self-lubricating guide fabric component 2 is made of self-lubricating resin, exhibiting low friction. This allows it to maintain a smooth surface during long-term contact with the non-woven fabric, reducing surface damage caused by friction. Materials used for the self-lubricating guide fabric component 2 include, but are not limited to, nylon, polytetrafluoroethylene, polyoxymethylene, and polyetheretherketone.

[0025] like Figure 1 and Figure 3As shown, the surface of the self-lubricating guide fabric 2 is provided with two micro-protrusion areas. The diagonal micro-protrusions 11 in the two micro-protrusion areas are symmetrically arranged with the center plane of the self-lubricating guide fabric 2 as the plane of symmetry. The center plane of the self-lubricating guide fabric 2 is located at the middle position in the length direction of the self-lubricating guide fabric 2 and is perpendicular to the axis of the self-lubricating guide fabric 2. The diagonal micro-protrusions 11 in the micro-protrusion areas extend obliquely in the same direction, and the diagonal micro-protrusions 11 are protrusions protruding outward on the surface of the self-lubricating guide fabric 2. In this embodiment, as shown... Figure 3 As shown, in one micro-protrusion arrangement area, the twill micro-protrusions 11 extend at a gradually decreasing angle from left to right, while in another micro-protrusion arrangement area, the twill micro-protrusions 11 extend at a gradually decreasing angle from right to left. All the twill micro-protrusions 11 in the same micro-protrusion arrangement area are arranged sequentially along the axial direction of the self-lubricating guide fabric 2. The twill micro-protrusions 11 in the same micro-protrusion arrangement area are parallel to each other, and the horizontal distance between two adjacent twill micro-protrusions 11 is equal. The angle between the inclined extension direction of the twill micro-protrusions 11 and the axis of the self-lubricating guide fabric 2 is an acute angle. The direction of the twill micro-protrusions 11 is from the midpoint of the fabric inlet end of the self-lubricating guide fabric 2 outwards in the direction of fabric movement. Through this design structure, the non-woven fabric can be effectively spread out in the vertical movement direction.

[0026] like Figure 1 and Figure 2 As shown, the non-woven fabric winding fabric flatness adjustment device of this utility model also includes a fixing rod 4. A groove 10 is provided on the fixing mechanism 3 for the fixing rod 4 to pass through. At least two fixing rods 4 are provided. All fixing rods 4 are arranged sequentially along the length direction of the groove 10. The groove 10 is a vertically arranged rectangular groove. The length direction of the fixing rod 4 is parallel to the axis of the self-lubricating guide 2. The self-lubricating guide 2 is connected to the upper end of all fixing mechanisms 3 by bolts. The fixing rod 4 is used to guide the fixing mechanism 3 and guide the fixing mechanism 3 to move linearly in the vertical direction. The fixing mechanism 3 causes the part connected to the self-lubricating guide 2 to deform, which helps to adjust the fabric tension and flatness.

[0027] like Figure 1 and Figure 2As shown, the non-woven fabric winding fabric surface flatness adjustment device of this utility model also includes a stop bar 7, which is fixedly mounted on a fixed rod 4. Multiple stop bars 7 are provided, and each fixed mechanism 3 is located between two stop bars 7. The stop bars 7 limit the movement of the fixed mechanism 3 on the fixed rod 4. Each fixed mechanism 3 has an adjustment knob 5 below it. The adjustment knob 5 is vertically mounted on a knob mounting plate 6, with its upper end contacting the bottom surface of the fixed mechanism 3. By rotating the adjustment knob 5, the adjustment knob 5 moves vertically relative to the knob mounting plate 6, thereby pushing the fixed mechanism 3 upwards or causing it to move downwards under its own weight. The fixed mechanism 3 is made of metal.

[0028] like Figure 1 and Figure 2 As shown, the non-woven fabric winding flatness adjustment device of this utility model also includes a gantry frame 8, a fixing rod 4, and a knob mounting plate 6 fixedly mounted on the gantry frame 8. The fixing rod 4 is located above the knob mounting plate 6. Two fixing rods 4 are provided, arranged sequentially along the vertical direction. The fixing rods 4 pass through the slide grooves 10 of all fixing mechanisms 3. All fixing mechanisms 3 are arranged sequentially along the length direction of the fixing rods 4 and are equidistantly distributed. The knob mounting plate 6 is horizontally set and has multiple adjusting knobs 5. All adjusting knobs 5 are arranged sequentially along the length direction of the knob mounting plate 6 and are equidistantly distributed. The length direction of the knob mounting plate 6 is parallel to the axis of the self-lubricating guide fabric component 2.

[0029] The non-woven fabric surface flatness adjustment device is arranged before the winding device. The above design can control the flatness of the adjustable fabric surface flatness device to a certain extent by manually rotating the adjustment knob 5. It can adjust the tension of the non-woven fabric surface to a certain extent, so that the fabric surface is evenly spread out. This helps to make the tension of the non-woven fabric surface uniform at each point during winding, avoids defects such as wrinkles and folds in the non-woven fabric surface, and facilitates subsequent processing steps such as lamination.

[0030] like Figure 1 As shown, the non-woven fabric winding surface flatness adjustment device is located between two pairs of traction guide rollers 1. The two traction guide rollers 1 of the same pair are arranged vertically. The non-woven fabric passes through the two traction guide rollers 1. The axis of the traction guide roller 1 is parallel to the axis of the self-lubricating guide component 2.

[0031] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
