Description

Technical Field

[0001] This invention relates to the field of lamination equipment technology, and in particular to lamination equipment for inorganic non-metallic materials and metal substrates. Background Technology

[0002] With the trend towards integrated waterproofing and building envelope, single waterproofing or enclosure materials are no longer sufficient to meet the comprehensive requirements of modern buildings for "waterproofing performance + structural strength + construction efficiency." Among them, fiberglass mesh-based asphalt shingles, due to their fiberglass mesh base, possess excellent tensile strength, waterproof durability, and compatibility with asphalt coatings, making them one of the mainstream materials for roof waterproofing projects. Meanwhile, metal substrates, with their high strength, wind uplift resistance, and ease of installation, are widely used in building envelope systems.

[0003] Chinese patent application CN116409047A discloses a fiberboard lamination processing device, including a forming base, a U-shaped frame, a lifting cylinder, a lamination mold, a connecting cylinder, and an output mechanism. The U-shaped frame is installed on the upper end of the forming base, and the lifting cylinder connects the U-shaped frame to the lamination mold. The lamination mold is connected to the output mechanism via the connecting cylinder. During the first lamination, evenly distributed embedding tubes are inserted from top to bottom into the raw material layer, ensuring that the adhesive is evenly injected into all areas of the raw material layer, thus increasing the adhesive distribution area. After injection, the embedding tubes rise to a suitable height for a second lamination, until the lower end face of the embedding tube is at the same horizontal level as the lower end face of the laminate. At this point, the second lamination is complete. The two laminations increase the extrusion density and also fill the holes left by the embedding tubes when they were first inserted into the raw material layer. The second lamination and the even injection of adhesive improve the coagulation degree of each area of ​​the fiberboard blank, thus improving the quality of the finished product.

[0004] In existing lamination equipment, the pressure rollers are prone to radial bending due to uneven force or insufficient processing precision, resulting in uneven contact pressure on the roller surface. At the same time, the thickness fluctuation between the metal substrate and the woven inorganic fiber cotton leads to uneven compaction of the composite board, affecting the quality.

[0005] To address these issues, this invention proposes an inorganic non-metallic material and metal substrate lamination device. Summary of the Invention

[0006] In view of the problems existing in the prior art, the present invention is proposed.

[0007] To solve the above technical problems, an inorganic non-metallic material and metal substrate lamination equipment was designed, including: a frame body supporting two horizontally arranged linear pressure roller structures; a floating pressure roller structure connected to the frame body and parallel to the linear pressure roller structures, forming a lamination gap between the floating pressure roller structures that allows the composite material to pass through; and two sets of gap adjustment structures arranged perpendicular to the linear pressure roller structures, which suspend the floating pressure roller structures and adjust the size of the lamination gap through their own expansion and contraction, driving the floating pressure roller structures to press against the composite material with constant pressure.

[0008] A dynamic pressure compensation structure, assembled within the floating pressure roller structure, senses the pressure exerted by the floating pressure roller structure against the composite material and compensates for the pressure exerted on the composite material by the floating pressure roller structure through its own expansion and contraction. The floating pressure roller structure includes an action rod mounted on a frame and arranged parallel to the linear pressure roller structure; multiple sets of flexible couplings linearly laid on the action rod; and multiple flexible rollers interlaced between the sets of flexible couplings. The flexible rollers are connected via adjacent sets of flexible couplings. The composite material presses against the flexible rollers to transmit force to the flexible couplings, causing the flexible couplings to extend or retract to dynamically adjust the distance between the flexible rollers and the linear pressure roller structure.

[0009] The dynamic pressure compensation structure includes a cylinder connecting plate mounted on an acting bending rod and arranged horizontally, an adjusting cylinder mounted on the cylinder connecting plate, a pressure response unit connected to the output shaft end of the adjusting cylinder, and a pressure sensing unit connected to the end of the pressure response unit away from the adjusting cylinder; wherein, the pressure sensing unit abuts against the surface of the floating roller and moves up and down with the floating roller to transmit force to the pressure response unit, and the pressure response unit controls the length of the adjusting cylinder to adjust the output end according to the pressure fluctuation value.

[0010] As a preferred embodiment of the inorganic non-metallic material and metal substrate lamination equipment of the present invention, the floating pressure roller structure further includes lateral connecting shafts disposed on both sides of the flexible coupling. The lateral connecting shafts are movably connected to the frame body and are linked by the gap adjustment structure to move linearly up and down.

[0011] The gap adjustment structure includes a sensing cylinder, a telescopic structure connected to the output end of the sensing cylinder, and a connecting block connected to the telescopic structure opposite to the end of the sensing cylinder. The sensing cylinder is connected to a side connecting shaft through the telescopic structure and the connecting block to adjust the position of the floating pressure roller structure.

[0012] As a preferred embodiment of the inorganic non-metallic material and metal substrate lamination equipment of the present invention, the flexible roller includes a floating roller shaft, a plurality of bearings evenly distributed along the axial direction of the floating roller shaft, and a floating roller wheel sleeved on the bearings; during operation, the composite board passes through the lamination gap and rubs to drive the floating roller wheel to rotate.

[0013] As a preferred embodiment of the inorganic non-metallic material and metal substrate lamination equipment of the present invention, the flexible coupling includes a three-axis connector connected to the bending rod, a bending shaft connected to the floating roller shaft, and an adaptive displacement adjustment unit disposed between the three-axis connector and the bending shaft; the adaptive displacement adjustment unit includes a displacement spring, spring washers connected to both ends of the displacement spring, and a telescopic short rod assembled between the two spring washers.

[0014] As a preferred embodiment of the inorganic non-metallic material and metal substrate lamination device of the present invention, the pressure response unit includes an upper support plate connected to the output end of the regulating cylinder, a lower support plate connected to the pressure sensing unit, and a pressure sensor stacked between the lower support plate and the upper support plate. The pressure sensor is provided with a strain gauge array and a signal output terminal for measuring the pressure transmitted by the lower support plate in real time and controlling the movement of the output end of the regulating cylinder.

[0015] As a preferred embodiment of the inorganic non-metallic material and metal substrate lamination equipment of the present invention, the pressure sensing unit includes a three-way rod connected to the end of the lower support plate away from the pressure sensor, a roller movably connected to the three-way rod, and a limiting piece assembled on the three-way rod; wherein the roller rolls against the surface of the floating roller shaft, and the limiting pieces are respectively disposed on both sides of the roller to limit the displacement of the roller.

[0016] As a preferred embodiment of the inorganic non-metallic material and metal substrate lamination equipment of the present invention, it further includes a drive structure: the drive structure includes a drive motor mounted on the frame body and a drive gear connected to the drive motor, the drive motor synchronously drives two linear pressure roller structures to rotate synchronously through the drive gear;

[0017] Both linear pressure roller structures include a linear pressure roller shaft that is mounted through the frame, a linear pressure roller wheel integrally connected to the linear pressure roller shaft, and driven gears assembled at both ends of the linear pressure roller shaft; the two driven gears located on the same side of the frame are respectively meshed with the drive gear so as to be driven by the drive gear to rotate in the same direction.

[0018] As a preferred embodiment of the inorganic non-metallic material and metal substrate lamination equipment of the present invention, two sets of floating pressure roller structures are staggered along the conveying direction of the composite material, and the radial projection of the roller of the first set of floating rollers and the roller of the second set of rollers form a complementary phase difference along the conveying direction of the composite material.

[0019] Two sets of parallel linear pressure roller structures are arranged along the transmission direction of the composite board. The two sets of linear pressure roller structures are connected by a linkage structure, and the two sets of linear pressure roller structures are synchronously transmitted through the linkage structure.

[0020] As a preferred embodiment of the inorganic non-metallic material and metal substrate lamination equipment of the present invention, the linkage structure includes two pulleys located at the ends of the linear pressure roller shaft, and a belt sleeved on the two pulleys. The belt synchronously drives the two pulleys to rotate, thereby synchronously driving the two sets of linear pressure roller structures to rotate synchronously.

[0021] The beneficial effects of this invention are as follows: This invention solves the problem of uneven pressure distribution caused by insufficient straightness of the pressure rollers and fluctuations in material thickness in traditional lamination equipment through a multi-level collaborative design integrating a frame, linear pressure roller structure, floating pressure roller structure, gap adjustment structure, and dynamic pressure compensation structure. Specifically, two sets of linear pressure roller structures support and directionally transport the composite material through synchronous rotation. The parallel floating pressure roller structure forms a dynamic compensation mechanism through the linkage design of acting bending rods, flexible couplings, and flexible rollers. Flexible couplings are linearly distributed on the acting bending rods, and the staggered flexible rollers are connected by adjacent flexible couplings. When the composite material presses the flexible rollers, the flexible couplings extend and retract to dynamically adjust the gap between the flexible rollers and the linear pressure roller structure, achieving adaptive local pressure balance. Two sets of gap adjustment structures symmetrically suspend the floating pressure roller structure. Through the coordinated extension and retraction of the sensing cylinder and the telescopic structure, the lamination gap size is globally adjusted and a constant pressure output is maintained. Simultaneously, the dynamic pressure compensation structure, assembled within the floating pressure roller structure, senses changes in the material pressure in real time. Through closed-loop control of the pressure sensor and the adjusting cylinder, it actively compensates for local pressure deviations, improving lamination quality. Attached Figure Description

Detailed Implementation

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0035] Existing equipment for laminating inorganic non-metallic materials with metal substrates typically includes an alignment and feeding module, a metal substrate conveying module, a surface pretreatment device module, an adhesive coating module, and a lamination device.

[0036] The alignment and feeding modules are respectively set at the input and output ends of the metal substrate conveying module. They are used to tension the woven inorganic fiber cotton roll and achieve uniform unwinding. This structure usually includes a tension motor and a tension adjustment device to ensure stable feeding.

[0037] The metal substrate conveying module includes a conveying platform that carries the metal substrate and moves it linearly, and a positioning guide rail disposed on the conveying platform. The positioning guide rail is used to laterally limit the metal substrate to ensure that the substrate maintains a straight motion trajectory during the conveying process and avoids deviation that affects the composite accuracy.

[0038] The surface pretreatment device module is configured as a dust removal fan and is located at the conveying inlet end of the conveying platform. It removes dust, debris and other impurities from the surface of the metal substrate by blowing with high-speed airflow, thereby cleaning the surface of the metal substrate and improving the adhesion during subsequent lamination.

[0039] The adhesive application module, located in the middle of the conveying module, is used to apply adhesive to the surface of a metal substrate or a fiberglass mesh-based asphalt shingle substrate. The fiberglass mesh-based asphalt shingle substrate adopts a fiberglass mesh structure. The adhesive application module includes a dispensing machine, a precision metering pump, and a multi-axis robotic arm. The multi-axis robotic arm drives the dispensing machine to apply the adhesive to the metal substrate in an array by dotting. The precision metering pump is used to accurately control the output of the adhesive to ensure that the amount of adhesive applied is uniform and stable.

[0040] In this application, it can be used not only for bonding glass fiber mesh structures made of asphalt shingles to metal substrates, but also for bonding woven reinforced inorganic fiber cotton to metal substrates.

[0041] The laminating equipment has a winding module near the output end of the metal substrate conveying module. Through heating and pressurization, the glued metal substrate and the glass fiber mesh are melted, bonded, and cured to form a composite board, achieving high-strength bonding between the two. A cutting module is also set between the alignment winding module and the laminating equipment. The cutting module cuts the glass fiber mesh along the edge of the metal substrate to output the composite board. The woven inorganic fibers continue to be wound by the alignment winding module to ensure the tension of the woven inorganic fibers and the recovery of excess material.

[0042] In the lamination process of fiberglass mesh and metal substrate, the straightness of the pressure roller structure and the consistency of the composite thickness further restrict the lamination quality. Existing lamination equipment generally adopts an integral extrusion structure composed of one or two pressure roller shafts. During long-term use, the pressure rollers are prone to radial bending due to uneven stress or insufficient processing precision, resulting in non-uniform distribution of contact pressure between the roller surface and the metal substrate and fiberglass mesh. The bending protrusions create local overpressure, which may damage the coating on the surface of the metal substrate or crush the pore structure of the fiberglass mesh; the depressions, on the other hand, suffer from insufficient pressure, resulting in insufficient melting and penetration of the adhesive, and weak bonding at the composite interface.

[0043] Meanwhile, even with an adaptive pressure adjustment structure to match the material thickness by matching the spacing between the two pressure rollers, if the metal substrate has rolling tolerances or local warping, or if the fiberglass mesh exhibits thickness fluctuations due to the mesh laying process, the thickness of the laminated board will be inconsistent along its length or width. The rigid extrusion mode of traditional pressure rollers cannot dynamically compensate for this thickness deviation, resulting in excessive pressure in thick areas and insufficient compaction in thin areas, severely affecting the flatness and uniformity of the mechanical properties of the composite board. This uneven extrusion problem caused by pressure roller straightness defects and material thickness fluctuations makes it difficult for existing lamination equipment to achieve uniform compaction across the entire width using an adaptive pressure structure when processing high-precision composite boards.

[0044] Example 1

[0045] Reference Figures 1-8 As shown, this is the first embodiment of the present invention. This embodiment provides an apparatus for laminating inorganic non-metallic materials with a metal substrate, comprising:

[0046] The frame 11 supports two horizontally arranged linear pressure roller structures 41. The two sets of linear pressure roller structures 41 rotate to support the composite board horizontally and directionally convey the composite board.

[0047] A floating pressure roller structure 51 connected to the frame body 11 and parallel to the linear pressure roller structure 41 forms a lamination gap between itself and the linear pressure roller structure 41 that allows the composite board to pass through.

[0048] Two sets of gap adjustment structures 31 are set perpendicular to the straight pressure roller structure 41, and a floating pressure roller structure 51 is suspended. The floating pressure roller structure 51 is adjusted in coordination by its own extension and contraction to drive the floating pressure roller structure 51 to press against the composite board with constant pressure.

[0049] The dynamic pressure compensation structure 61, which is assembled in the floating pressure roller structure 51, senses the pressure of the floating pressure roller structure 51 pressing against the composite material, and compensates the pressure of the floating pressure roller structure 51 on the composite material by its own extension and contraction.

[0050] The control system, which is connected to the gap adjustment structure 31 and the dynamic pressure compensation structure 61, is used to sense the overall thickness and local thickness of the composite board so as to adjust the overall lamination gap through the gap adjustment structure 31 and to achieve local pressure compensation through the dynamic pressure compensation structure 61.

[0051] The floating pressure roller structure 51 includes an action rod 514 mounted on the frame body 11 and arranged parallel to the linear pressure roller structure 41, multiple sets of flexible couplings 513 linearly laid on the action rod 514, and multiple flexible rollers 512 interlaced between the multiple sets of flexible couplings 513. The flexible rollers 512 are connected by two adjacent sets of flexible couplings 513. The composite plate presses the flexible rollers 512 to transmit force to the flexible couplings 513, so as to drive the flexible couplings 513 to extend or retract to dynamically adjust the distance between the flexible rollers 512 and the linear pressure roller structure 41.

[0052] Specifically, there are multiple sets of dynamic pressure compensation structures 61, which are interspersed between multiple sets of flexible couplings 513, with the dynamic pressure compensation structure 61 located in the middle of two adjacent flexible couplings 513.

[0053] like Figure 2 and Figure 3 As shown, the floating pressure roller structure 51 also includes a side connecting shaft 511 of the flexible coupling 513 on both sides. The side connecting shaft 511 is movably connected to the frame body 11 and is linked by the gap adjustment structure 31 to move linearly up and down to adjust the gap between the floating pressure roller structure 51 and the linear pressure roller structure 41 to adapt to composite boards of different thicknesses.

[0054] like Figures 7-8 As shown, the two sets of gap adjustment structures 31 are symmetrical about the frame body 11, and are respectively arranged vertically on the side connecting shafts 511. The gap adjustment structure 31 includes a sensing cylinder 311, a telescopic structure connected to the output end of the sensing cylinder 311, and a connecting block 317 connected to the end of the telescopic structure opposite to the sensing cylinder 311. The sensing cylinder 311 is connected to the side connecting shaft 511 through the telescopic structure and the connecting block 317 to adjust the position of the floating pressure roller structure 51.

[0055] Specifically, the gap adjustment structure 31 also includes a mounting base 312 assembled on the frame body 11, and the telescopic structure is assembled on the mounting base 312 to achieve its own stability.

[0056] In one embodiment, the telescopic structure includes a lower insertion rod 313 connected to the output end of the sensing cylinder 311, an outer cylinder 315 sleeved on the surface of the lower insertion rod 313, and a sensing spring 314 disposed between the outer cylinders 315. The inner diameter of the outer cylinder 315 is the same as the diameter of the lower insertion rod 313, and the lower insertion rod 313 extends into the inner cavity of the outer cylinder 315 by a certain distance.

[0057] Specifically, during the process of hoisting the floating pressure roller structure 51 by the telescopic structure, the force is stretched, and the length of the extension of the sensing spring 314 under the force is less than the distance that the lower insertion rod 313 extends into the outer cylinder 315.

[0058] Specifically, the sensing spring 314 is configured as a high-strength spring.

[0059] Specifically, the end of the sensing spring 314 away from the connecting block 317 is connected to a spring seat, and a pressure sensor 316 is provided between the spring seat and the lower insertion rod 313; the lower insertion rod 313 is connected to the sensing spring 314 through the pressure sensor 316 and the spring seat, and the sensing spring 314 is fixed to the bottom of the inner wall of the outer cylinder 315.

[0060] Working principle: The gap adjustment structure 31 is used to globally adjust the lamination gap between the floating pressure roller structure 51 and the linear pressure roller structure 41, and transmit constant pressure. The sensing cylinder 311 is connected to the side connecting shaft 511 via a telescopic structure to drive the floating pressure roller structure 51 to move up and down as a whole, adapting to the thickness of composite panels of different thicknesses. Meanwhile, the lower insertion rod 313 is inserted into the inner cavity of the outer cylinder 315, forming a sliding fit to ensure stable telescopic direction. The sensing spring 314 is located inside the outer cylinder 315, and its stiffness must match the lamination pressure requirements of the composite panel. When the floating pressure roller structure 51 is subjected to the reaction force of the panel, the sensing spring 314 compresses or extends, absorbing pressure fluctuations through elastic deformation to maintain a constant contact pressure. The spring seat is fixed to the bottom of the inner wall of the outer cylinder 315. The pressure sensor 316 is located between the spring seat and the lower insertion rod 313, monitoring the compression of the sensing spring 314 in real time and feeding the signal back to the control system. When the pressure deviates from the set value, the sensing cylinder 311 adjusts the position of the output end to rebalance the compression of the sensing spring 314 and maintain the constant pressure output of the floating pressure roller structure 51 to the composite material.

[0061] Example 2

[0062] Reference Figure 2 and Figure 3As shown, this is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the flexible roller 512 includes a floating roller shaft 5122, a plurality of bearings 5123 distributed at equal intervals along the axial direction of the floating roller shaft 5122, and a floating roller 5121 sleeved on the bearings 5123. During operation, the composite board passes through the lamination gap and rubs to drive the floating roller 5121 to rotate.

[0063] Reference Figure 2 and Figure 3 As shown, the flexible coupling 513 includes a three-axis connector 5131 connected to the bending rod 514, a bent shaft 5134 connected to the floating roller shaft 5122, and an adaptive displacement adjustment unit disposed between the three-axis connector 5131 and the bent shaft 5134. The adaptive displacement adjustment unit includes a displacement spring 5133, spring washers 5132 connected to both ends of the displacement spring 5133, and a telescopic short rod assembled between the two spring washers 5132. Specifically, the three-axis connector 5131 is vertically arranged, the two spring washers 5132 are horizontal, the telescopic short rod is perpendicular to the two spring washers 5132, the displacement spring 5133 is sleeved on the telescopic short rod, and the telescopic short rod and the displacement spring 5133 move synchronously to drive the flexible coupling 513 to extend and retract in the longitudinal direction in response to the different thicknesses of the composite material at different positions.

[0064] Working Principle: By optimizing the structural design of the flexible roller 512 and the flexible coupling 513, the dynamic compensation capability of the laminating equipment for local thickness fluctuations in the composite board is further improved, ensuring uniform pressure across the entire width. Specifically, the flexible roller 512 consists of a floating roller shaft 5122, bearings 5123 distributed axially at equal intervals, and sleeved floating rollers 5121. The flexible roller 512 is arranged parallel to the bending rod 514 and is connected to the bending rod 514 through the flexible couplings 513 on both sides. Multiple bearings 5123 are distributed axially at equal intervals along the floating roller shaft 5122, and each bearing 5123 has an independent floating roller 5121 sleeved on its outer ring. When the composite board passes through the lamination gap, the moving friction of the board drives the floating roller 5121 to rotate around the bearing 5123, reducing the sliding friction between the roller and the board and avoiding scratches on the material surface. Each floating roller 5121 and its corresponding bearing 5123 constitute an independent floating unit. When the thickness of the composite board increases in a local area, such as when glass fiber accumulation at the corresponding lamination position causes fluctuations in the composite board thickness, the floating roller 5121 in that area is lifted, causing the corresponding bearing 5123 to slightly deflect or rise on the floating roller shaft 5122, and the flexible coupling 513 contracts. Conversely, when the thickness decreases, the floating roller 5121 sinks, and the flexible coupling 513 relatively extends. This segmented floating design allows each floating roller 5121 to independently adjust its height according to local pressure changes, forming a "multi-point adaptive" local pressure compensation.

[0065] Example 3

[0066] For reference Figures 1-8 As shown, this is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that the inorganic non-metallic material and metal substrate lamination equipment further includes a dynamic pressure compensation structure 61. The dynamic pressure compensation structure 61 includes a cylinder connecting plate 612 mounted on the actuating bending rod 514 and arranged horizontally, an adjusting cylinder 611 mounted on the cylinder connecting plate 612, a pressure response unit connected to the output shaft end of the adjusting cylinder 611, and a pressure sensing unit connected to the end of the pressure response unit away from the adjusting cylinder 611. The pressure sensing unit abuts against the surface of the floating roller 5121 and moves up and down with the floating roller 5121 to transmit force to the pressure response unit. The pressure response unit controls the adjusting cylinder 611 to adjust the length of the output end according to the pressure fluctuation value.

[0067] In one embodiment, the pressure response unit includes an upper support plate 613 connected to the output end of the regulating cylinder 611, a lower support plate 615 connected to the pressure sensing unit, and a pressure sensor 614 stacked between the lower support plate 615 and the upper support plate 613. The pressure sensor 614 is provided with a strain gauge array and a signal output terminal for measuring the pressure transmitted by the lower support plate 615 in real time and controlling the movement of the output end of the regulating cylinder 611.

[0068] In one embodiment, a strain gauge array is attached to a pressure sensor 614 to convert the mechanical pressure transmitted by the floating roller 5121 into a change in resistance value; a signal output terminal is used to convert the resistance change signal into an electrical signal and transmit it to the control system.

[0069] In one embodiment, the pressure sensing unit includes a three-way rod 616 connected to the lower support plate 615 at the end opposite to the pressure sensor 614, a roller 617 movably connected to the three-way rod 616, and a limiting piece 618 mounted on the three-way rod 616; wherein the roller 617 rolls against the surface of the floating roller shaft 5122, and the limiting pieces 618 are respectively disposed on both sides of the roller 617 to limit the displacement of the roller 617.

[0070] Specifically, the pressure sensing unit achieves precise monitoring and dynamic compensation of local pressure on the floating roller 5121 through a coordinated design of mechanical linkage and electrical signal feedback. When the composite board passes through the lamination gap, if the local thickness of the composite board increases, the floating roller 5121 in that area is lifted, pushing the roller 617, which is in rolling contact with its surface, upward. Conversely, when the thickness decreases, the floating roller 5121 sinks, and the roller 617 descends accordingly. The rolling friction between the roller 617 and the surface of the floating roller shaft 5122 reduces wear while ensuring the sensitivity of pressure transmission and avoiding interference with pressure sensing accuracy due to frictional resistance.

[0071] After receiving the pressure transmitted by the three-way rod 616, the lower support plate 615 applies the force to the pressure sensor 614 stacked on it. When pressure is applied, the elastic body of the sensor undergoes slight deformation, causing a change in the resistance value of the strain gauge. The change in resistance is converted into a voltage signal proportional to the pressure via a Wheatstone bridge circuit. This voltage signal is transmitted to the control system, completing the conversion from analog to digital signal. The control system compares the real-time pressure signal with a preset threshold. If a pressure deviation is detected, an adjustment command is generated to drive the cylinder to compensate for the pressure.

[0072] Based on the mechanical compensation of Example 2, Example 3 introduces dynamic pressure closed-loop control to achieve active pressure compensation: by adjusting the cylinder 611 to actively apply pressure, it is ensured that the floating roller 5121 always adheres to the plate with the set pressure, preventing the flexible coupling 513 of Example 2 from releasing pressure excessively due to avoidance, which would lead to insufficient pressure between the glass fiber mesh and the metal substrate. The sensing cylinder 311 can actively supplement the pressure to avoid insufficient adhesive penetration.

[0073] In Example 2, the flexible coupling 513 and the segmented floating roller 5121 passively absorb local material thickness fluctuations through spring deformation and the deflection of the flexible roller 512 shaft, forming a first-level basic pressure buffer to avoid stress concentration on the rigid pressure roller. In Example 3, the dynamic pressure closed-loop control structure, based on this mechanical compensation, uses roller 617, three-way rod 616, and pressure sensing unit to collaboratively capture the micro-displacement changes of the floating roller 5121 in real time. Combined with the response of the strain gauge array and adjusting cylinder 611, it actively regulates the local pressure intensity, forming a second-level precise pressure compensation. This not only compensates for the instantaneous pressure deviation caused by spring avoidance in Example 2, but also achieves constant pressure fluctuations across the entire width through the linkage of global clearance adjustment and local dynamic compensation. With the synergy of both, the mechanical deformation of the flexible coupling 513 reduces dependence on the electrical control system and energy consumption, while the closed-loop control gives the passive compensation structure adaptive adjustment capabilities, protecting the metal substrate coating and glass fiber porous structure from excessive compression, and ensuring consistent adhesive penetration depth and improved interfacial bonding strength.

[0074] like Figure 1 and Figure 2 As shown, the inorganic non-metallic material and metal substrate lamination equipment also includes a drive structure 21: the drive structure 21 includes a drive motor 211 mounted on the frame 11 and a drive gear 212 connected to the drive motor 211. The drive motor 211 drives two linear pressure roller structures 41 to rotate synchronously through the drive gear 212.

[0075] Both linear pressure roller structures 41 include a linear pressure roller shaft 412 that is mounted through the frame body 11, a linear pressure roller wheel 411 integrally connected to the linear pressure roller shaft 412, and driven gears 413 assembled at both ends of the linear pressure roller shaft 412; the two driven gears 413 located on the same side of the frame body 11 mesh with the drive gear 212 respectively, so as to be driven by the drive gear 212 to rotate in the same direction.

[0076] In one embodiment, two sets of floating pressure roller structures 51 are staggered along the conveying direction of the composite material. The two sets of floating pressure roller structures 51 are arranged in a spatially staggered manner. The radial projection of the roller of the first set of floating rollers 5121 and the roller of the second set form a complementary phase difference distribution along the conveying direction of the composite material. That is, the installation position of the second set of floating rollers 5121 is offset laterally by half the distance of the first set of floating rollers 5121. At the same time, the assembly gap of the dynamic pressure compensation structure 61 is reserved between the adjacent floating rollers 5121, thereby ensuring that the compression blind area not covered by the first set of floating rollers 5121 is completely filled by the second set of floating rollers 5121 during the continuous conveying process of the composite material, realizing uninterrupted relay pressure application across the entire width.

[0077] There are two sets of gap adjustment structure 31 and dynamic pressure compensation structure 61, and the two sets of gap adjustment structure 31 and dynamic pressure compensation structure 61 correspond to the two sets of floating pressure roller structure 51 respectively.

[0078] Two sets of parallel linear pressure roller structures 41 are arranged along the transmission direction of the composite board. The two sets of linear pressure roller structures 41 correspond to two sets of floating pressure roller structures 51. The two sets of linear pressure roller structures 41 are connected by a linkage structure 71, and the two sets of linear pressure roller structures 41 are synchronously driven through the linkage structure 71.

[0079] In one embodiment, the linkage structure 71 includes two pulleys 711 located at the end of the linear pressure roller shaft 412, and a belt 712 sleeved on the two pulleys 711. The belt 712 synchronously drives the two pulleys 711 to rotate, thereby synchronously driving the two sets of linear pressure roller structures 41 to rotate synchronously.

[0080] The inorganic non-metallic material and metal substrate lamination equipment also includes a connecting structure: the connecting structure includes a first connecting structure 81 and a second connecting structure 82 connected to the frame body 11, and two sets of linear pressure roller structures 41 are respectively the first pressure roller structure and the second pressure roller structure. The first connecting structure 81 is disposed on the side of the first pressure roller structure away from the second pressure roller structure, and the second connecting structure 82 is disposed between the first pressure roller structure and the second pressure roller structure.

[0081] In the example, the first connecting structure 81 includes a first connecting frame 811 mounted on the frame body 11, and two curved guide plates 812 disposed on the first connecting frame 811. A waist-shaped channel is formed between the two sets of curved guide plates 812 to support and guide the composite material. The minimum channel width of the waist-shaped channel formed by the two curved guide plates 812 is slightly larger than the width of the metal substrate. The composite material is transitioned and straightened by the first connecting structure 81 into the lamination gap and is laminated by the first pressure roller structure.

[0082] The second connecting structure 82 includes a second connecting plate 821 mounted on the frame 11, and two straight guide plates 822 mounted on the second connecting plate 821. A channel width slightly larger than the thickness of the metal substrate is provided between the two straight guide plates 822. The composite board is transitionally driven by the second connecting structure 82 into the lamination gap of the second pressure roller structure to compensate for the part of the laminated composite board that was not laminated by the first pressure roller structure. At the same time, the composite board is laminated a second time to make the adhesion between the limiting cotton and the metal substrate tighter.

The present invention is also not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of the present invention should fall within the patent coverage of the present invention.
