Description

Technical Field

[0001] This utility model relates to the field of glass fiber production technology, and in particular to a glass fiber winding spool. Background Art

[0002] Currently, Teflon-wound spools are used in fiberglass production to reduce oil migration from the inner ring of the spool, thus reducing the problem of yellow and white fibers. However, after 1-2 months of use, significant fiber adhesion and a large amount of waste fiber appear on the Teflon-wound spools. Cleaning is necessary at this point, but even after cleaning, a small amount of fiber adhesion remains. After another 0.5-1 month of use, significant fiber adhesion reappears, making further cleaning more difficult. Furthermore, after cleaning, the Teflon-wound spools show more fuzz and breakage, necessitating the use of new Teflon-wound spools.

[0003] Therefore, the problem of Teflon filament sticking in existing technology affects its service life. Frequent replacements will lead to reduced production efficiency and increased operating costs. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the Teflon winding spools in the background art by providing a glass fiber winding spool.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A glass fiber winding spool includes a Teflon winding spool, the two ends of which are provided with coated cloth, and the coated cloth and the Teflon winding spool are bonded together by hot melt film.

[0007] Furthermore, the hot melt film is made of Teflon film. Preferably, the Teflon film is bonded to the Teflon-coated cloth and the Teflon winding bobbin under the action of a high-temperature hot knife and pressure, while maintaining a certain degree of flexibility. Using Teflon film to make the hot melt film can ensure the bonding effect between the coated cloth and the Teflon winding bobbin after hot melting.

[0008] Furthermore, the width of the coated fabric is: (width of Teflon winding bobbin - width of original yarn bobbin) / 2+1cm. If the width is too narrow, the risk of yarn sticking increases, and if the width is too wide, slippage is likely to occur, affecting the yarn drawing operation and the drying effect of the original yarn bobbin.

[0009] Preferably, the width of the coated fabric is 4-6cm. For example, it can be 4cm, 4.5cm, 5cm, 5.5cm, 6cm, etc., as long as it is within the range of 4-6cm.

[0010] Furthermore, the coated fabric is coated with Teflon material.

[0011] Furthermore, the surface of the Teflon winding bobbin is provided with several evenly distributed bumps and recesses.

[0012] Furthermore, the protrusions and grooves of the bumps are shaped as circles, ellipses, or regular polygons.

[0013] Furthermore, the shapes of the protrusions and grooves of the bump block are set to be different.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. The special wire spool designed in this utility model has no obvious sizing agent particles on both sides after long-term use, which reduces the occurrence of wire sticking to the spool and saves waste wire costs;

[0016] 2. The surface of the coated fabric on this winding bobbin is smoother than the middle part, and 53EF effectively reduces the generation of skin particles, thereby reducing the sticking of yarn on both sides, so that it basically does not need to be cleaned, reducing the cost of cleaning.

[0017] 3. This winding bobbin does not affect the production, drying, or product quality of glass fiber. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings. The technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0022] like Figure 1 and Figure 2 As shown, a glass fiber winding spool includes a Teflon winding spool 3, which is the base of the winding spool of this utility model. The two ends of the Teflon winding spool 3 are provided with coated cloth 1, and the coated cloth 1 and the Teflon winding spool 3 are thermally bonded together by a hot melt film 2.

[0023] Furthermore, the hot melt film 2 is made of Teflon film. Preferably, the Teflon film is bonded to the Teflon-coated cloth 1 and the Teflon winding bobbin 3 under the action of high temperature hot knife and pressure, and maintains a certain degree of flexibility. The use of Teflon film to make the hot melt film 2 can ensure the bonding effect between the coated cloth 1 and the Teflon winding bobbin 3 after hot melting.

[0024] Furthermore, the width of the coated fabric 1 is: (Teflon winding bobbin width - original yarn bobbin width) / 2 + 1cm. A width that is too narrow increases the risk of yarn sticking, while a width that is too wide can easily cause slippage, affecting the yarn drawing operation and the drying effect of the original yarn bobbin. In this embodiment, the width of the coated fabric 1 is set to 5cm.

[0025] Furthermore, the surface of the Teflon winding bobbin 3 is provided with several evenly distributed bumps 4. The design of the bumps helps to fix the winding bobbin to the drawing machine head, and at the same time facilitates the winding of glass fiber without slippage.

[0026] Furthermore, the protrusions and grooves of the bump block 4 are shaped as one of circles, ellipses, or regular polygons.

[0027] Furthermore, the protrusions and grooves of the bump block 4 can be set to different shapes, such as the protrusions being circular and the grooves being elliptical, etc.

[0028] Furthermore, the coated fabric 1 is coated with Teflon material, which makes the surfaces of both ends of the Teflon-coated bobbin 3 relatively smooth. This prevents the coating agent from remaining on the surface excessively during fiber production, thus preventing the formation of granular skin and effectively reducing the problem of yarn sticking on both sides. The yarn bobbin is thicker in the middle and thinner on both sides. The appropriate use of Teflon-coated fabric on both sides has virtually no impact on the drying effect of the yarn bobbin.

[0029] Working Principle: This utility model of a fiber winding spool consists of a Teflon winding spool 1, a heat-melting film 2, and a Teflon-coated fabric 3, and is a type of glass fiber winding spool. The design employs a Teflon-coated fabric 3 of a certain width, which is bonded to both sides of the Teflon winding spool with the heat-melting film 2, essentially flush with the raised surface of the Teflon winding spool. The relatively smooth surface of the Teflon-coated fabric 3 reduces the formation of skin particles. The heat-melting film 2 is used to fix the Teflon-coated fabric 3, reducing damage to the Teflon-coated fabric 3. This winding spool meets production needs while reducing fiber adhesion; without fiber adhesion, cleaning is unnecessary, reducing cleaning costs.

[0030] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
