Description

Technical Field

[0001] The present invention relates to the technical field of fabric impregnation, and more particularly to a fabric impregnation device and an impregnation method thereof. Background Art

[0002] Fabric impregnation refers to the process of forcing liquid treatment agents (such as resins, latex, flame retardants, waterproofing agents, softeners, dyes, functional nanomaterial dispersions, etc.) to penetrate into the fabric fibers or fully adhere to the fiber surface. Its core goal is to allow the treatment agent to be evenly and fully distributed inside the fabric, rather than just staying on the surface, thereby giving or enhancing the fabric specific properties (such as strength, hardness, flame retardancy, waterproofing, antibacterial, conductivity, etc.). The impregnation process is widely used in industrial textiles (such as coated base fabrics, filter materials, reinforcement materials), functional clothing fabrics, home decoration fabrics, composite material prepregs and other fields.

[0003] The existing fabric impregnation device directly immerses the fabric into the impregnation liquid. When the fabric is an elastic fabric, impurities adhere to the surface of the elastic fabric during the production process. When the elastic fabric is wound, the impurities will penetrate deep into the gaps of the elastic fabric and are difficult to remove. Therefore, during the impregnation, the impurities deep in the gaps of the elastic fabric block the penetration of the impregnation liquid, thereby affecting the impregnation effect of the fabric and causing the fabric impregnation to be unqualified. Summary of the Invention

[0031] It should be noted that the fabric unwound by the unwinding mechanism 6 is elastic fabric, the immersion box 3 is open at the top, the supporting seat 4 is movably arranged above the immersion box 3, the winding mechanism 5 is located in the middle of the supporting seat 4, the unwinding mechanism 6 is located at one end of the supporting seat 4, the fabric surrounds the supporting seat 4, the bottom of the flushing seat 8 is provided with a spray hole, the tensioning mechanism 9 rolls and clamps the side of the fabric, and the impregnation box 1 is also provided with a smoke box 11 to facilitate the discharge of smoke, and the control panel 12 is convenient for control and adjustment.

[0032] Furthermore, an installation box 2 is provided at the bottom of the impregnation box 1, and a first linear drive 21 is installed inside the installation box 2. The output end of the first linear drive 21 is connected to a connecting plate 41, and the connecting plate 41 is fixed on both sides of the supporting seat 4. A rotation drive 42 is installed on the connecting plate 41, and the output end of the rotation drive 42 is connected to the winding mechanism 5. A liquid storage tank 22 is installed inside the installation box 2, and an output pipe 81 is connected between the liquid storage tank 22 and the flushing seat 8.

[0033] It should be noted that the first linear drive 21 drives the supporting seat 4 to rise through the connecting plate 41 to facilitate loading, and the connecting plate 41 drives the supporting seat 4 to descend for impregnation operation. The liquid storage tank 22 stores impregnation liquid inside, and the impregnation liquid is transported to the flushing seat 8 through the output pipe 81.

[0034] Furthermore, the tensioning mechanism 9 includes an upper clamping plate 91 and a lower clamping plate 92, and the lower clamping plate 92 is located below the upper clamping plate 91. Rolling wheels 93 are installed on the opposite side of the upper clamping plate 91 and the lower clamping plate 92, and the rolling wheels 93 roll the side of the bottom fabric of the supporting seat 4.

[0035] It should be noted that the upper clamping plate 91 and the lower clamping plate 92 are respectively arranged above and below the side of the fabric, and the rolling wheel 93 is rotatably arranged on the corresponding upper clamping plate 91 and the lower clamping plate 92.

[0036] Furthermore, the tensioning mechanism 9 also includes a third linear drive 43, and the third linear drive 43 is installed at both ends of the immersion tank 3. A fixing plate 94 is provided between the upper clamping plate 91 and the lower clamping plate 92, and the fixing plate 94 is connected to the output end of the third linear drive 43.

[0037] It should be noted that the third linear drive 43 drives the fixed plate 94 to push and pull the fixed plate 94 at a set frequency. The upper clamping plate 91 and the lower clamping plate 92 are installed on the corresponding fixed plate 94 by bolts, and the distance between the upper clamping plate 91 and the lower clamping plate 92 can be flexibly adjusted.

The rolling of the rolling wheel 93 facilitates the transmission of the fabric, and the third linear drive 43 drives the fixing plate 94 to push and pull according to the frequency, so that the fabric can be "breathed" and stretched, so that the fabric pores can be dynamically opened and reset. After opening, the fabric pores expand by 20%-40%, the fiber gaps open, and the impurities are released. The adsorption force of the mass, after the tension is released, the fabric shrinks and resets, and the impregnation liquid is transported to the flushing seat 8 through the liquid storage tank 22 and the output pipe 81, and the impregnation liquid is sprayed to the fabric when the pores of the fabric are opened, which can perform directional liquid flow impact. The impregnation liquid impacts from top to bottom to form pressure penetration, flushing large particles of impurities on the surface of the fabric, and cooperating with the micro-pump effect generated by the dynamic breathing of the fabric to squeeze out some trapped bubbles and free impurities. The whole can be impact-immersed in the impregnation liquid after the pores of the fabric are expanded, cleaning impurities in the pores of the fabric, so that the impregnation liquid can be better immersed in the interior of the fabric, thereby improving the impregnation effect of the fabric.
