Description

Technical Field

[0001] This invention relates to the technical field of rock wool composite board processing and production equipment, specifically to a mesh wrapping and folding system for processing rock wool composite boards and its usage method. Background Technology

[0002] The rock wool composite board is wrapped with fiberglass mesh on all four sides along its length, with a polymer cement mortar finishing layer on the inner and outer sides. Its rock wool core is either a board made of vertically woven rock wool strips or a horizontally woven rock wool core. Compared to ordinary bare rock wool boards, rock wool composite boards offer advantages such as high strength, water resistance, strong adhesion, and good labor protection. Installation is convenient and pollution-free, and it adheres firmly to the base wall. It solves problems associated with bare rock wool boards, such as settling upon contact with water, delamination and slippage, low tensile strength, and skin irritation caused by rock wool fibers, effectively improving project quality. It can be widely used in wall insulation projects for various building structures. During the production and processing of rock wool composite boards, fiberglass mesh needs to be installed on all four sides along the length of the rock wool core, and a polymer cement mortar finishing layer needs to be applied to the inner and outer sides. Currently, rock wool composite panels are typically produced manually. This involves cutting the rock wool core material to the designed dimensions, manually wrapping fiberglass mesh around all four sides of the assembled rock wool core material along its length, and then manually applying a polymer cement mortar finish to the inner and outer surfaces. This method is inefficient, produces inconsistent products, and is costly in terms of labor. In rock wool composite panel production lines, the quality of the fiberglass mesh wrapping directly affects product quality; therefore, manual wrapping is commonly used, impacting production line efficiency and increasing labor costs. In existing rock wool composite panel production lines, fiberglass mesh is first laid on a conveyor belt, followed by a polymer cement mortar finish. The rock wool core material is then laid on top of this finish, and mechanical devices are used to naturally wrap the fiberglass mesh. A pressing mechanism is then used to press the surface, improving the adhesion between the polymer cement mortar finish and the rock wool core material. However, in actual operation, the tightness of the fiberglass mesh wrapping cannot be guaranteed by natural folding alone, resulting in a large number of defective or waste products. Summary of the Invention

[0003] The purpose of this invention is to provide a wrapping and folding system and method for processing rock wool composite panels. This system can realize continuous natural wrapping and inward extrusion of glass fiber mesh, improve the tightness of the glass fiber mesh wrapping, ensure the yield rate, has good adjustability, can adapt to products of different specifications, and is highly practical.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A system for wrapping and folding fiberglass mesh for processing rock wool composite panels includes a first transmission device and a second transmission device arranged sequentially. Lateral limiting plates are adjustable on both sides of the first and second transmission devices. A closing support device, a folding and pressing device, and a layering device are installed on the first transmission device. The folding and pressing device includes a first gantry support, a transverse support adjustable on the first gantry support, a pressing roller adjustable on the transverse support, an outer folding roller on the first gantry support, and an inner folding roller on the transverse support. A folding gap exists between the outer and inner folding rollers. The fiberglass mesh passes through the folding gap via the closing support device and is layered and folded by the layering device. One or more sets of bidirectional folding devices are installed on the second transmission device. Each bidirectional folding device includes a second gantry support, a vertical adjustment component mounted on the second gantry support, a support plate mounted on the vertical adjustment component, a drive mechanism fixedly mounted on the support plate, and two sets of folding roller shafts mounted on the drive mechanism. The two sets of folding roller shafts rotate relative to each other, folding the fiberglass mesh towards the center.

[0006] Preferably, the first transmission device includes a first support frame, a plurality of first transmission shafts rotatably mounted on the first support frame, and a first transmission belt mounted on the first transmission shafts.

[0007] Preferably, the surface of the first transmission belt is provided with a plurality of protrusions.

[0008] Preferably, the second transmission device includes a second support frame, multiple second transmission shafts rotatably mounted on the second support frame, and a second transmission belt mounted on the second transmission shafts, wherein the second transmission shafts are dynamically connected to the first transmission shafts.

[0009] Preferably, the transverse support is mounted on the first gantry support via a lifting adjustment assembly, which is a worm gear screw jack, a hydraulic cylinder, or an electric push rod.

[0010] Preferably, the layering device includes an upper support plate and a lower support plate arranged vertically, with both ends of the fiberglass mesh located on the upper support plate and the lower support plate, respectively.

[0011] Preferably, the closing support device consists of two fiberglass mesh support plates fixedly mounted on the lateral limiting plate. The two fiberglass mesh support plates are arranged in a V-shape. The fiberglass mesh first passes through the two fiberglass mesh support plates in an upward open shape, then passes through the folding gap to make the fiberglass mesh vertical or slightly inward, and finally passes through the two upper support plates and the lower support plate to make the two ends of the fiberglass mesh fold inward.

[0012] Preferably, the bidirectional screen-making device is arranged in two sets in sequence, with each set of screen-making rollers in one set having one screen-making roller shaft; and each set of screen-making rollers in the other set having two screen-making roller shafts.

[0013] Preferably, the supporting horizontal plate is provided with sliders at both ends, and vertical supports are fixedly installed on both sides of the second gantry bracket. Slide rails are fixedly installed on the vertical supports, and the sliders are slidably installed on the slide rails.

[0014] A method for using a mesh wrapping and folding system for processing rock wool composite panels, the method comprising the following steps:

[0015] Step 1: Parameter adjustment. Adjust the interval between the pressing roller and the first transmission device and the interval between the rubbing roller shaft and the second transmission device according to the thickness of the semi-finished product. Adjust the interval between the two lateral limiting plates according to the width of the semi-finished product.

[0016] Step 2: Install the fiberglass mesh. Place the fiberglass mesh from both sides of the semi-finished product onto the end support device, the folding gap, and the layering device in sequence. Avoid wrinkling the fiberglass mesh during installation.

[0017] In this invention, the system can naturally fold and tighten an open, upward-facing fiberglass mesh inwards, resulting in good continuity and smoothness of operation. The included end-closing support device, folding and pressing device, and layering device allow the open ends of the fiberglass mesh to naturally fold inwards, achieving a smooth wrapping process and preventing wrinkles in the fiberglass mesh. The height of the pressing rollers and the spacing between the lateral limiting plates can be adjusted as needed, making operation simple and convenient, and applicable to products of different specifications.

[0018] Several protrusions are provided on the surface of the first conveyor belt. When the pressing roller squeezes the semi-finished product consisting of glass fiber mesh, polymer cement mortar plaster layer and rock wool core material on the first conveyor belt, the protrusions cause the glass fiber mesh to be partially squeezed into the polymer cement mortar plaster layer, improving the connection reliability between the two and also increasing the tightness of the bond between the polymer cement mortar plaster layer and the rock wool core material, thereby improving the yield.

[0019] The bidirectional twisting device compresses the fiberglass mesh from both ends towards the center, resulting in a more compact wrapping. This facilitates subsequent fixing of the fiberglass mesh and application of the second layer of polymer cement mortar, improving product consistency and yield. The vertical adjustment component allows for height adjustment of the twisting assembly, adapting to products of different thicknesses and offering good versatility. Two sets of bidirectional twisting devices prevent the fiberglass mesh from springing back, further enhancing the tightening effect. Attached Figure Description

[0032] A layering device 7 is fixedly installed on the first transmission device 1. The fiberglass mesh passes through the closing support device 5, through the folding gap, and then through the layering device 7 to achieve layered folding. In one embodiment, the layering device 7 includes an upper support plate 70 and a lower support plate 71 arranged vertically, with both ends of the fiberglass mesh located on the upper support plate 70 and the lower support plate 71, respectively.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The method of using a mesh wrapping and folding system for processing rock wool composite panels, as shown, includes the following steps:

[0035] Step 1: Parameter adjustment. Adjust the interval between the pressing roller 62 and the first transmission device 1, and the interval between the rubbing roller shaft 84 and the second transmission device 2, according to the thickness of the semi-finished product. Adjust the interval between the two lateral limiting plates 3 according to the width of the semi-finished product, so that the interval between the two lateral limiting plates 3 matches the width of the semi-finished product. Adjust the interval between the pressing roller 62 and the first transmission belt 12 to adjust the extrusion pressure and ensure the adhesion between the rock wool core material and the polymer cement mortar plaster layer. Adjust the interval between the rubbing roller shaft 84 and the second transmission belt 22 to adjust the rubbing force and ensure the rubbing effect.

[0036] Step two: Install the fiberglass mesh. Place the fiberglass mesh from both sides of the semi-finished product sequentially onto the closing support device 5, the folding gap, and the layering device 7, avoiding wrinkles during installation. During operation, the fiberglass mesh first passes through two fiberglass mesh support plates in an upward-opening shape, then passes through the folding gap to make the fiberglass mesh vertical or slightly inward-curving, and finally passes through two upper support plates 70 and lower support plates 71 to fold the two ends of the fiberglass mesh inward.

[0037] This system processes the semi-finished products generated from the three processes of laying fiberglass mesh, laying polymer cement mortar plastering layer on the fiberglass mesh, and laying rock wool core material on the polymer cement mortar plastering layer.

[0038] The above embodiments are merely illustrative of the concept and implementation of the present invention and are not intended to limit it. Under the concept of the present invention, technical solutions without substantial changes are still within the scope of protection.
