[0002] In the field of road maintenance and construction, crack patching tape is a commonly used material used to repair road cracks, prevent moisture penetration, and extend the service life of roads. However, in actual applications, traditional crack patching tape has some shortcomings. First, existing crack patching tape production equipment can usually only cut a single size, which limits its adaptability to cracks of different widths. For example, when faced with narrower or wider cracks, products of different specifications are often required, which increases construction costs and inventory management difficulties. Secondly, the bonding properties of crack patching tape directly affect the repair effect and durability. Due to the limitations of its formula and process, traditional crack patching tape does not have strong enough adhesion to the surface of asphalt roads, and is prone to falling off, especially in severe weather conditions.

[0003] Furthermore, existing seam tapes have poor environmental adaptability. Their performance can deteriorate under varying climatic conditions, such as high humidity, strong UV exposure, or extreme temperature fluctuations. For example, while traditional PE film offers some waterproofing properties, it can age and become brittle under prolonged UV exposure, thus losing its protective properties. Summary of the Invention

[0004] The utility model aims to provide a laminating machine for glass fiber cloth, so as to solve the problems of poor bonding effect, insufficient durability and environmental adaptability of existing seam tapes caused by uneven application of tackifiers.

[0005] To achieve the above-mentioned purpose, a laminating machine for glass fiber cloth is provided, which includes a box body, a film feed port is provided on one side wall of the box body, and a rolling spraying mechanism is provided inside the box body on the side of the film feed port. The rolling spraying mechanism includes a viscosity enhancer spraying roller provided on the upper part of the box body, and a heating roller is also provided at a corresponding position below the viscosity enhancer spraying roller inside the box body. A driving mechanism is connected to one side of the viscosity enhancer spraying roller and the heating roller.

[0006] As a further improvement of this technical solution, the drive mechanism includes a bottom plate arranged on an outer wall of the box body, and a drive motor is provided on the bottom plate. The drive motor is fixedly connected to the driving gear through a first connecting shaft. The first connecting shaft is inserted into the interior of the box body and is also fixedly connected to the heating roller.

[0007] As a further improvement of this technical solution, a second connecting shaft is provided at a corresponding position above the side wall of the box body. The upper end of the driving gear is engaged with a driven gear, and the driven gear is fixedly connected to the second connecting shaft. The second connecting shaft is inserted into the interior of the box body and is also fixedly connected to the viscosity enhancer spraying roller.

[0008] As a further improvement of this technical solution, a thickener feeding chamber is provided inside the thickener spraying roller, a thickener tank is provided at the upper end of the box body, the thickener feeding chamber is connected to the thickener tank through a connecting pipe, and the thickener spraying roller is also provided with several first small holes leading to the thickener feeding chamber.

[0009] As a further improvement of the present technical solution, an electric heating rod is provided inside the heating roller, and a plurality of second small holes leading to the electric heating rod are also provided on the heating roller.

[0010] As a further improvement of the present technical solution, a discharge conveyor is provided inside the box body on one side of the rolling spraying mechanism, and side panels are provided on both sides of the discharge conveyor.

[0011] As a further improvement of the present technical solution, a fan is provided at the top of the interior of the box at a position corresponding to the discharge conveyor device.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This fiberglass cloth laminating machine features equipment improvements that enable the slitting of road crack tape in multiple sizes, from 3cm to 5cm to 7cm. This improvement allows the tape to flexibly address crack repair needs of varying widths, reducing construction costs and inventory management difficulties. This multi-size cutting function improves construction efficiency and flexibility, adapting to a wider range of application scenarios, thereby reducing overall construction costs and increasing construction convenience.

[0014] 2. This fiberglass cloth laminating machine significantly improves the product's viscosity by optimizing the seam tape formula and introducing a highly effective tackifier. This enhanced bonding ensures a stronger bond between the seam tape and the asphalt road surface, maintaining excellent adhesion even in adverse weather conditions such as rain, snow, and high temperatures. This not only enhances repair effectiveness but also extends the tape's service life, reducing the need for frequent repairs and thus lowering maintenance costs.

[0015] 3. This fiberglass cloth laminating machine replaces traditional PE film with fiberglass cloth, significantly improving the durability and environmental adaptability of the seam tape. Fiberglass cloth offers higher tensile strength, improved weather and UV resistance, and can maintain excellent performance in harsh environments such as high and low temperatures and high humidity. This makes the seam tape less susceptible to aging, cracking, or shedding over long-term use, extending its service life and ensuring stable performance in various climates.

[0016] 4. This fiberglass cloth laminating machine features an optimized tackifier spray roller and internal feed chamber, combined with evenly distributed apertures, ensuring uniform application of the tackifier to the fiberglass cloth, enhancing the bond strength and consistency between the tape and the road surface. The uniform heat transfer from the heated roller further enhances the tackifier's adhesion, while the two pressure rollers effectively flatten the film, reducing wrinkles and significantly improving the overall quality and durability of the product.

[0025] See also Figure 1-Figure 3 As shown, the present embodiment aims to provide a laminating machine for glass fiber cloth, comprising a housing 1, a film feed port 13, a rolling spray mechanism 21, a heating roller 15, a drive mechanism 2, and a discharge conveyor 4, among other main components. First, a film feed port 13 is provided on one side wall of the housing 1 for introducing the glass fiber cloth to be processed into the interior of the housing 1. Inside the housing 1, a rolling spray mechanism 21 is provided on one side of the film feed port 13. The rolling spray mechanism 21 comprises a tackifier spray roller 14 located above the interior of the housing 1, and a heating roller 15 located below the tackifier spray roller 14. A tackifier feed chamber 16 is provided inside the tackifier spray roller 14, which is connected to the tackifier tank 3 at the upper end of the housing 1 via a connecting pipe 12. The tackifier spray roller 14 is also provided with a plurality of first small holes 18 leading to the tackifier feed chamber 16, thereby ensuring that the tackifier can be evenly sprayed onto the surface of the glass fiber cloth.

[0026] The drive mechanism 2 is mounted on a bottom plate 5 on one outer wall of the housing 1. A drive motor 6 is mounted on the bottom plate 5. The drive motor 6 is fixedly connected to a driving gear 7 via a first connecting shaft 10. The first connecting shaft 10 extends through the interior of the housing 1 and is fixedly connected to a heating roller 15. Furthermore, a second connecting shaft 11 is positioned above the corresponding side wall of the housing 1. The upper end of the driving gear 7 engages with a driven gear 8, which is fixedly connected to the second connecting shaft 11. The second connecting shaft 11 extends through the interior of the housing 1 and is fixedly connected to a tackifier spray roller 14. This dual-shaft design enables the tackifier spray roller 14 and the heating roller 15 to operate synchronously and in coordination.

[0027] An electric heating rod 17 is provided inside the heating roller 15, and a plurality of second small holes 19 are provided on the heating roller 15, leading to the electric heating rod 17. These small holes not only help to evenly distribute heat, but also can exhaust air between the film and the heating roller 15, reducing the generation of bubbles and wrinkles, thereby improving the flatness and quality of the product.

[0028] Inside the box 1, a discharge conveyor 4 is located on one side of the rolling coating mechanism 21. Side panels 9 are located on either side of the discharge conveyor 4 to ensure the material remains stable during transport. A fan 20 is located at the top of the box 1, corresponding to the discharge conveyor 4, to cool the treated material, ensuring rapid solidification and optimal performance.

[0029] To meet the needs of repairing cracks of varying widths, the device has been improved to enable slicing in various sizes, including 3cm, 5cm, and 7cm. By adjusting the position of the cutting tool or replacing different cutting modules, it can flexibly adapt to various road crack widths, improving construction efficiency and applicability.

[0030] In terms of viscosity improvement, formula optimization and the addition of a tackifier significantly increase the viscosity of the road joint tape, enhancing its adhesion to the asphalt road surface. The design of the tackifier spray roller 14 ensures that the tackifier is evenly sprayed onto the fiberglass cloth, reducing performance inconsistencies caused by localized excess or insufficient tackifier, and improving the overall quality and consistency of the product.

[0031] Furthermore, replacing the traditional PE film with fiberglass cloth has significantly enhanced the mechanical strength and aging resistance of the seam tape. Fiberglass cloth offers improved weather and abrasion resistance, maintaining excellent performance in harsh environments and extending the service life of the seam tape.

[0032] The temperature control and cooling systems throughout the production process have also been optimized, ensuring consistent and stable product quality. Through these improvements, the utility model provides an efficient and versatile road seam tape production solution suitable for a variety of road repair scenarios and has broad application prospects.

[0033] Working principle: First, the glass fiber cloth to be processed enters the interior of the box 1 through the film feed port 13. The viscosity enhancer spraying roller 14 draws the viscosity enhancer from the viscosity enhancer tank 3 and sprays it evenly onto the surface of the glass fiber cloth through the first small hole 18. Subsequently, the glass fiber cloth passes through the heating roller 15, and the electric heating rod 17 evenly transfers heat through the second small hole 19, so that the viscosity enhancer is better solidified and its bonding properties are enhanced. The drive motor 6 drives the heating roller 15 through the first connecting shaft 10 and the driving gear 7, and at the same time drives the viscosity enhancer spraying roller 14 through the second connecting shaft 11 and the driven gear 8 to ensure that the two work synchronously. The treated glass fiber cloth is sent out by the discharge conveyor 4 and cooled and shaped by the fan 20. During the whole process, the side panel 9 ensures the stability of the material during transportation. In addition, by adjusting the position of the cutting tool or replacing different cutting modules, cutting of various sizes such as 3cm, 5cm, 7cm, etc. can be achieved to meet the repair needs of gaps of different widths.
