Description

Technical Field

[0001] This invention specifically relates to a nonwoven quilted cement-based composite material blanket and its production equipment, belonging to the field of cement blanket production technology. Background Technology

[0002] Cement blankets typically consist of a mesh structure comprised of a top layer, a bottom layer, and a connecting layer. The cavity between the top and bottom layers is filled with cement-based dry powder. After installation, the cement blanket hardens upon contact with water, forming a concrete-like structure. In the application of cement blankets, they are first laid in the desired location, and then water is poured on them to allow the cement within to harden, forming a concrete-like structure. However, most existing cement blankets use pure cement and lack the aggregate found in concrete, making them prone to cracking during the hardening process. Due to the limitations of the upper and lower layers of cement blankets, it is generally difficult to add conventional aggregates to the middle of the cement blanket. This means that during the curing process, the cement inside the cement blanket can only rely on the upper and lower layers and the middle connecting layer as adhesion points to prevent cracking. However, the interior of the cement blanket can still form some dry cracked lumps due to the curing of pure cement, which reduces the overall performance of the cement blanket. To address this, Chinese Patent Publication No. CN116876454A discloses a high-strength, ultra-fast curing cement blanket, in which the middle matrix includes a skeleton and a curable mixture, solving the problem in the prior art where the pure cement inside the cement blanket is prone to dry cracking and clumping, reducing the performance of the cement blanket. However, when existing cement blankets are used in waterproofing applications, leakage is prone to occur at the seams, resulting in reduced waterproofing performance. In addition, existing cement blankets are generally thin and have low erosion resistance, making them unsuitable for applications such as irrigation canals, drainage ditches, and embankment drainage ditches. When the filling core of the cement blanket is thick, continuous production cannot be achieved. Summary of the Invention

[0003] To address the aforementioned issues, this invention proposes a nonwoven quilted cement-based composite material blanket and its production equipment, which can adapt well to and fit various terrains; it can be tightly bonded to the base surface, the cement blanket has a large filling core thickness, it can adapt to various water storage or canal applications, and it can achieve continuous production of composite material blankets.

[0004] The nonwoven quilted cement-based composite material blanket of the present invention comprises: The outer sheath comprises a top layer and a bottom layer made of nonwoven fabric; the top and bottom layers are made of anti-aging polyester or polypropylene fibers and have a certain thickness (≥1.8mm) and a unit area mass (≥220g / ㎡); the bottom surface of the top layer and the top surface of the bottom layer are coated with waterproof adhesive by roller at intervals; the outer edges of the top and bottom layers are integrally sewn together; the waterproof adhesive surfaces of the top and bottom layers are pressed together and sewn together by fiber sewing thread; the fiber sewing thread is made of synthetic fibers such as polyester, which has high strength, wear resistance and anti-aging properties; A dry concrete mix core layer is filled inside the outer layer and disposed between the waterproof adhesive surfaces.

[0005] A computerized quilting machine is used to sew the top layer, bottom layer, and dry concrete core layer (10kg / ㎡) together with a stitch spacing of 1~12mm and a micro-wavy curve pattern, thus stitching the top layer, bottom layer, and dry concrete core layer into one piece; the position of the waterproof adhesive surface on the dry concrete core layer is limited; a non-woven quilted cement-based composite material blanket with a certain width (≥1.0m) and thickness (≥10mm) and uniform thickness is produced; the elastic pressing of the waterproof adhesive surface is used to wrap the fiber sewing thread; thus, the sewn position has a waterproof effect.

[0006] Furthermore, the dry concrete mix core layer includes dry concrete mix containing cellulose; the cellulose content is 12-20%; the dry concrete mix core layer is pre-filled into the inner side of the outer layer, requiring no on-site preparation and avoiding over-hydration issues. The dry concrete mix core layer undergoes a hydration reaction upon contact with water, and due to the addition of 12-20% cellulose in the mix, the size and shape of the composite material blanket can still be adjusted on-site within 2 hours to ensure close adhesion to the base surface. It can harden to 80% strength within 24 hours, forming a concrete structural layer with a certain thickness (≥10mm) and possessing compressive and flexural strength.

[0007] A production equipment for nonwoven quilted cement-based composite material blankets, used to produce nonwoven quilted cement-based composite material blankets, comprising: A production platform, wherein an inlet roller is provided at one end of the production platform and a shaping groove is provided at the other end; The fabric hopper has a hollow bottom and is located on the top surface of the production platform, near one end of the inlet roller.

A sewing pressing unit includes a roller groove on a production platform and perpendicular to the forming groove; a lower pressing roller is provided inside the roller groove, a bracket is fixed above the lower pressing roller, and an upper pressing roller is installed on the bracket; A computerized quilting machine, wherein the computerized quilting machine is mounted on the output end of the sewing pressing unit via a frame; the sewing end of the computerized quilting machine is directly opposite the shaping groove; A winding and traction device is located at the outer end of the production platform and at the output end of the computer quilting machine.

[0008] During production, two sets of nonwoven fabric rolls that have been glued and cured are first fed to the guide roller and the top surface of the frame. Next, the nonwoven fabric rolls on the side of the guide roller are pulled to the winding and traction equipment as the bottom layer of the outer sheath. Then, the nonwoven fabric rolls on the top surface of the frame are pulled to the winding and traction equipment as the top layer of the outer sheath. Next, the fabric hopper, outer sheath shaping and sealing unit, and sewing and pressing unit are lowered. Then, the material is fed into the feeding hopper through the feeding unit and feeding pipe, feeding the raw material of the dry concrete mixture core layer into the fabric hopper. Next, the electric dispersing paddle unit is activated, and the winding and traction equipment is activated with a delay. The bottom layer passes through the thickness-fixing channel, and after passing through the thickness-fixing channel carrying the raw material, it undergoes secondary thickness fixing through the pressure roller, and is then sealed... While the top and bottom layers are pressed together by the edge pressure rollers, the top and bottom layers are sewn together by an edge-sealing sewing machine. Then, the material continues to move into the sewing and pressing unit, where the waterproof adhesive surfaces of the top and bottom layers are pressed together by the lower and upper pressing rollers. When the bottom layer carrying the material moves to the lower and upper pressing rollers, the ends of the two sets of nonwoven fabric rolls are sealed by a computerized quilting machine. Next, the waterproof adhesive surface is sewn together by the computerized quilting machine while it is pressed together. After the winding and traction equipment winds up to the set thickness, the computerized quilting machine stitches two lines on the two sets of nonwoven fabric rolls, with the middle of the two lines being the cut-off point. After the cut-off point is wound back to the winding and traction equipment for production winding.

[0009] Furthermore, both the upper and lower pressing rollers include a roller frame, on which a pressing roller body driven by a motor is mounted via bearings.

[0014] Furthermore, the first elastic pressing unit and the second elastic pressing unit include a mounting plate fixed to the frame or fabric bin. Multiple guide columns are slidably installed on the mounting plate at intervals. A first floating plate or a second floating plate is fixed to the bottom of each guide column. A limit nut is screwed onto the top surface of the mounting plate. A spring body is provided on the bottom surface of the mounting plate. The spring body can push the first floating plate or the second floating plate downward, so that the edge sealing roller on the first floating plate adaptively presses against both sides of the top surface of the top layer, and the pressure roller on the second floating plate adaptively presses against both sides of the bottom surface of the bottom layer. The bottom of the edge sealing roller or the pressure roller is subjected to force, which can push the first floating plate or the second floating plate upward, so that the guide column can slide upward.

[0015] Furthermore, a top-level unwinding frame is fixed on the frame base, which is used to support the top-level nonwoven fabric roll.
