DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the application more obvious and easy to understand, the specific embodiments of the application will be described in detail below with reference to the accompanying drawings.

[0033] In the following description, many specific details are set forth in order to provide a thorough understanding of the application, but the application can 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 application, therefore the application is not limited to the specific embodiments disclosed below.

[0034] Second, the "one embodiment" or "embodiments" referred to herein are intended to encompass a particular feature, structure, or characteristic in at least one implementation of the application. The appearances of the "in one embodiment" or "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive.

[0035] Generally, the existing equipment for laminating inorganic non-metallic materials and metal substrates usually includes a register feeding module, a metal substrate conveying module, a surface pretreatment device module, a glue applying module, and a laminating device, wherein;

[0036] The register feeding module is arranged at the input end and the output end of the metal substrate conveying module respectively, and is used for tensioning the inorganic fiber cotton roll and achieving uniform feeding. The structure usually includes a tension motor and a tension adjusting device to ensure stable feeding.

[0037] The metal substrate conveying module includes a conveying platform for carrying the metal substrate and linearly moving the metal substrate, and a positioning guide rail arranged on the conveying platform. The positioning guide rail is used for limiting the metal substrate in the transverse direction, so as to ensure that the substrate maintains a linear motion track during the conveying process and avoids deviation to affect the composite accuracy.

[0038] The surface pretreatment device module is configured as a dust removal fan and is arranged at the conveying inlet end of the conveying platform. The dust removal fan blows away the dust, debris and other impurities on the surface of the metal substrate by means of high-speed airflow, so as to clean the surface of the metal substrate and improve the adhesion during the subsequent compounding.

[0039] The glue applying module is arranged in the middle part of the conveying module, and is used for applying adhesive on the surface of the metal substrate or the glass fiber mesh structure asphalt shingle base. The glass fiber mesh structure asphalt shingle base uses a glass fiber mesh structure. The glue applying module includes a dispensing machine, a precision metering pump, and a multi-axis mechanical arm. The multi-axis mechanical arm drives the dispensing machine to move so that the dispensing machine points and applies the adhesive on the metal substrate in an arrayed manner. The precision metering pump is used for accurately controlling the output amount of the adhesive, so as to ensure uniform and stable glue applying amount.

[0040] In the present application, not only the glass fiber mesh structure made of asphalt shingle material and the metal substrate can be combined, but also the mesh reinforced inorganic fiber cotton and the metal substrate can be combined.

[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 Fig. 1~Fig. 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 material to pass through.

[0048] Two sets of gap adjustment structures 31 arranged perpendicularly to the linear pressing roller structure 41, the hoisting floating pressing roller structure 51 adjusts the size of the laminating gap by itself and drives the floating pressing roller structure 51 to abut on the composite board with constant pressure;

[0049] The dynamic compensation structure assembled in the floating pressing roller structure 51 senses the pressure of the floating pressing roller structure 51 abutting on the composite board and compensates the pressure of the floating pressing roller structure 51 to the composite board by itself;

[0050] The control system connected with the gap adjustment structure 31 and the dynamic compensation structure senses the overall thickness and local thickness of the composite board to adjust the overall laminating gap through the gap adjustment structure 31 and realize local pressure compensation through the dynamic compensation structure;

[0051] The floating pressing roller structure 51 includes the action bending rod 514 arranged on the frame body 11 and arranged in parallel with the linear pressing roller structure 41, the multiple sets of flexible couplings 513 linearly laid on the action bending rod 514, the multiple flexible rollers 512 staggered and inserted between the multiple sets of flexible couplings 513, the flexible rollers 512 connected through the adjacent two sets of flexible couplings 513, the composite board extruding the flexible rollers 512 to transmit force to the flexible couplings 513 to drive the flexible couplings 513 to expand or contract to dynamically adjust the distance between the flexible rollers 512 and the linear pressing roller structure 41.

[0052] Specifically, the number of the dynamic compensation structure is multiple sets, the multiple sets of dynamic compensation structures are inserted between the multiple sets of flexible couplings 513, and the dynamic compensation structure is located in the middle of the adjacent two flexible couplings 513.

[0053] As shown in Fig. 2 and Fig. 3 The floating pressing roller structure 51 further includes the side connecting shaft 511 arranged on the flexible couplings 513 on both sides, the side connecting shaft 511 movably connected in the frame body 11 and linked with the gap adjustment structure 31 to move linearly up and down to adjust the gap size between the floating pressing roller structure 51 and the linear pressing roller structure 41 to adapt to the composite board with different thicknesses.

[0054] As shown in Fig. 7~Fig. 8 The two sets of gap adjustment structures 31 are symmetrical about the frame body 11 and are respectively arranged vertically on the two side connecting shafts 511, the gap adjustment structure 31 includes the sensing cylinder 311, the expansion structure connected to the output end of the sensing cylinder 311, the connecting block 317 connected to the end of the expansion structure away from the sensing cylinder 311, and the sensing cylinder 311 connected to the side connecting shaft 511 through the expansion structure and the connecting block 317 to adjust the position of the floating pressing roller structure 51.

[0055] Specifically, the gap adjustment structure 31 further comprises a mounting base 312 assembled on the frame body 11, and a telescopic structure assembled on the mounting base 312 to realize its own stability.

[0056] In an embodiment, the telescopic structure comprises a lower insertion rod 313 connected to the output end of the induction cylinder 311, an external cylinder 315 sleeved on the surface of the lower insertion rod 313, and an induction spring 314 arranged between the external cylinders 315. The inner diameter of the cylinder body of the external cylinder 315 is consistent with the diameter of the rod body of the lower insertion rod 313, and the lower insertion rod 313 extends into the inner cavity of the external cylinder 315 by a certain distance.

[0057] Specifically, the telescopic structure is stretched during the hoisting of the floating pressure roller structure 51, and the length of the induction spring 314 stretched under stress is less than the distance of the lower insertion rod 313 extending into the external cylinder 315.

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

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

[0060] Working principle: the gap adjustment structure 31 is used for globally adjusting the laminating gap between the floating pressure roller structure 51 and the linear pressure roller structure 41 and transmitting constant pressure; wherein the induction cylinder 311 is connected with the side connecting shaft 511 through the telescopic structure to drive the whole floating pressure roller structure 51 to move up and down, so as to adapt to the thickness of the composite board of different thicknesses; in the process, the lower insertion rod 313 is inserted into the inner cavity of the external cylinder 315 to form a sliding fit, so as to ensure the stability of the telescopic direction; the induction spring 314 is arranged in the external cylinder 315, and its stiffness needs to match the laminating pressure requirement of the composite board. When the floating pressure roller structure 51 is subjected to the reaction force of the board, the induction spring 314 is compressed or stretched, absorbs the pressure fluctuation through elastic deformation, maintains constant contact pressure, the spring seat is fixed to the inner wall bottom of the external cylinder 315, the pressure measuring sensor 316 is located between the spring seat and the lower insertion rod 313, and the compression amount of the induction spring 314 is monitored in real time, and the signal is fed back to the control system. When the detected pressure deviates from the set value, the induction cylinder 311 adjusts the position of the output end to rebalance the compression amount of the induction spring 314, so as to maintain the constant pressure output of the floating pressure roller structure 51 to the composite board.

[0061] Embodiment 2

[0062] Reference Fig. 2 and Fig. 3As shown, the second embodiment of the application is based on the previous embodiment, but the flexible roller 512 comprises a floating roller shaft 5122, a plurality of bearings 5123 distributed equidistantly along the floating roller shaft 5122 in the axial direction, and a floating roller wheel 5121 sleeved on the bearing 5123; in operation, the composite board passes through the laminating gap to drive the floating roller wheel 5121 to rotate by friction.

[0063] Referring to Fig. 2 and Fig. 3 As shown, the flexible coupling 513 comprises a three-axis connector 5131 connected to the action bending rod 514, a bending shaft 5134 connected to the floating roller shaft 5122, and an adaptive displacement adjustment unit arranged between the three-axis connector 5131 and the bending shaft 5134; the adaptive displacement adjustment unit comprises a displacement spring 5133, spring washers 5132 connected to both ends of the displacement spring 5133, and an extension short rod assembled between the two spring washers 5132; specifically, the three-axis connector 5131 is arranged vertically, the two spring washers 5132 are horizontal, the extension short rod is perpendicular to the two spring washers 5132, the displacement spring 5133 is sleeved on the extension short rod, and the extension short rod and the displacement spring 5133 are synchronously linked and displaced to drive the length of the flexible coupling 513 to expand or contract in the longitudinal direction to respond to the different thicknesses of the composite board 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 the local thickness fluctuation of the composite board is further improved, and the uniformity of the full-width pressure is ensured; specifically, the flexible roller 512 is composed of a floating roller shaft 5122, a plurality of bearings 5123 distributed equidistantly in the axial direction, and a sleeved floating roller wheel 5121; the flexible roller 512 is arranged parallel to the action bending rod 514 and connected to the action bending rod 514 through the flexible couplings 513 on both sides, the plurality of bearings 5123 are distributed equidistantly in the axial direction along the floating roller shaft 5122, and each bearing 5123 has an independent floating roller wheel 5121 sleeved on the outer ring; when the composite board passes through the laminating gap, the moving friction of the board drives the floating roller wheel 5121 to rotate around the bearing 5123, reduces the sliding friction between the roller and the board, and avoids scratching the material surface; each floating roller wheel 5121 and its corresponding bearing 5123 constitute an independent floating unit. When the local thickness of the composite board increases, such as the thickness fluctuation of the composite board caused by the accumulation of glass fibers at the laminating position, the floating roller wheel 5121 in this area is lifted, driving the corresponding bearing 5123 to deflect or lift slightly on the floating roller shaft 5122, and the flexible coupling 513 contracts; on the contrary, when the thickness decreases, the floating roller wheel 5121 sinks, and the flexible coupling 513 relatively elongates. This segmented floating design allows each floating roller wheel 5121 to independently adjust the height according to the local pressure change, forming a "multi-point adaptive" local pressure compensation.

[0065] Example 3

[0066] For reference Fig. 1~Fig. 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] The lower force plate 615 receives the pressure transmitted by the three-way lever 616 and then acts on the pressure sensor 614 laminated thereon; when the pressure is applied, the sensor elastomer is slightly deformed, causing the resistance value of the strain gauge to change. Through the Wheatstone bridge circuit, the resistance change is converted into a voltage signal proportional to the pressure. The voltage signal is transmitted to the control system to complete the conversion of the analog signal to the digital signal. The control system compares the real-time pressure signal with the preset threshold value, and generates adjustment instructions to drive the cylinder to act to compensate for the pressure if the pressure deviation is detected.

[0072] Example 3 introduces dynamic pressure closed-loop control on the basis of the mechanical compensation of Example 2 to achieve active pressure compensation: by adjusting the air cylinder 611 to actively apply pressure, it ensures that the floating roller 5121 always adheres to the plate at a set pressure, preventing the flexible coupling 513 of Example 2 from releasing pressure due to excessive avoidance, which in turn causes insufficient pressure between the glass fiber mesh and the metal substrate, and the sensing cylinder 311 can actively supplement the pressure to prevent insufficient adhesive penetration.

[0073] The flexible coupling 513 of Example 2 and the segmented floating roller 5121 passively absorb local material thickness fluctuations through spring deformation and flexible roller 512 shaft deflection, forming a first level of basic pressure buffer to avoid stress concentration of rigid pressure rollers; the dynamic pressure closed-loop control structure of Example 3, based on this mechanical compensation, captures the micro-displacement changes of the floating roller 5121 in real time through the roller 617, the three-way lever 616 and the pressure sensing unit, and actively adjusts the local pressure through the response of the strain gauge array and the adjusting cylinder 611, forming a second level of precise pressure compensation, which not only compensates for the instantaneous pressure deviation caused by the spring avoidance of Example 2, but also achieves constant pressure fluctuation across the full width through the linkage of global gap adjustment and local dynamic compensation. With the cooperation of the two, the mechanical deformation of the flexible coupling 513 reduces the dependence on the electric control system and energy consumption, while the closed-loop control gives the passive compensation structure the ability to adjust adaptively, protecting the metal substrate coating and glass fiber pore structure from excessive extrusion, and ensuring consistent adhesive penetration depth and improved interface bonding strength.
