Description

Technical Field

[0001] This invention relates to the technical field of thermal insulation material production, specifically to a composite production process for an AA structure composite thermal insulation board. Background Technology

[0002] Currently, building exterior wall insulation systems have increasingly higher requirements for fire safety and energy-saving performance. The composite structure of Class A fireproof rock wool board and vacuum insulation composite insulation board (VIP) has become an important development direction for high-performance insulation materials.

[0003] However, existing composite processes mostly employ manual stacking and simple pressing methods, which suffer from problems such as low positioning accuracy, easy delamination at the bonding interface, and susceptibility of the vacuum core material to impact damage. Especially in the process of laminating large-size panels, the lack of adaptive clamping and non-destructive pressing mechanisms makes it difficult to balance bonding strength and the integrity of the vacuum insulation panel.

[0004] In addition, the lack of effective pressure restraint during the curing stage often leads to warping and deformation of the boards, affecting the flatness of the finished product.

[0005] Therefore, there is an urgent need for a composite production process and supporting equipment that is highly automated, has strong process controllability, and can achieve "precise stacking - non-destructive compaction - shaping and pressure holding" in one integrated manner. Summary of the Invention

[0006] The purpose of this invention is to provide a composite production process and special equipment for AA structure composite insulation boards, so as to solve the problems of easy breakage of vacuum insulation boards, unreliable bonding of composite interfaces, rock wool fiber leakage and low degree of automation in the prior art, and to achieve high safety, high precision and high efficiency non-destructive composite manufacturing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A composite production process for an AA structure composite insulation board includes the following steps: S1. Precast Class A fireproof insulation board: With reinforcing ribs as the internal reinforcing skeleton, special structural adhesive is evenly coated on the left and right sides of the reinforcing ribs, and two rock wool boards are symmetrically bonded to the two sides of the reinforcing ribs. After preliminary curing, a Class A fireproof insulation board with an internal reinforcing skeleton is formed. S2. Precise stacking: Apply adhesive mortar to the upper surface of the vacuum insulation composite insulation board, and use the stacking mechanism of a special composite equipment to precisely align and stack the Class A fireproof insulation board on top of the vacuum insulation composite insulation board, ensuring that the edges of the two are aligned and the adhesive surfaces are completely covered. S3. Non-destructive pressing and bonding: The pressing mechanism of the bonding equipment applies uniform and controllable vertical pressure to make the Class A fireproof insulation board and the vacuum insulation composite insulation board fit tightly together without damaging the vacuum insulation core material, thus completing the initial bonding and obtaining the AA structure composite insulation board process part. S4. Shaping and pressure-holding curing: The AA structure composite insulation board process component is installed into the pressure-holding fixture and left to cure under constant pressure and standard temperature and humidity environment, so that the bonding mortar can be fully cured and form a stable bonding interface. S5. Demolding and Output of Finished Products: After curing is completed, release the constraints of the pressure-holding fixture, remove the molded AA-structure composite insulation board, and complete the production process.

[0008] Furthermore, in step S4, the curing time is 2-24 hours, the temperature is 10-35℃, and the relative humidity is 40-70%.

[0009] Preferably, the stacking mechanism includes a support frame, with multiple support feet evenly distributed at the bottom of the support frame, and two rows of inverted L-shaped support frames symmetrically arranged at the top of the support frame. A universal ball is installed at the top of each support frame, and a linear guide rail is horizontally fixed to the upper side of each support frame. A guide rail slider is slidably fitted onto the linear guide rail. All guide rail sliders on the same side are connected to a moving plate.

Its piston rod is connected upwards to a lifting plate. Hinge seats one are symmetrically connected to both sides of the lifting plate, and hinge seats two are respectively connected to the lower sides of the two moving plates. Hinge seats one and hinge seats two on the same side are hinged together by hinge strips.

[0010] Preferably, the pressing mechanism includes a pair of rodless cylinders, which are respectively installed on the upper part of the two side movable plates. A moving bar is vertically connected to the slider of each rodless cylinder. A fixed plate is provided between the two moving bars. Guide posts are vertically connected to both sides of the fixed plate. The guide posts slide with the moving bar on the same side through guide sleeves, and a helical spring is sleeved on the guide posts.

A pressing roller is rotatably installed in the mounting shell, and suction pipes are symmetrically connected to its upper side.

[0011] Preferably, the pressure-holding fixture includes a placement frame and a telescopic frame disposed above the placement frame. The placement frame has symmetrical positioning plates at its front and rear ends. The telescopic frame is composed of multiple X-shaped telescopic joints that are hinged together in sequence. A pressure bar is connected below the central hinge point of each telescopic joint, and side pressure rollers are respectively hinged to the lower ends of its four overhanging ends. The two ends of the pressure bar are detachably connected to the placement frame through industrial fasteners. Multiple notches are provided at horizontal intervals along the moving plate, and a lifting ring is connected above the central hinge point of each telescopic joint.

[0012] Furthermore, all the conveying rollers located on the same side are connected by a conveyor belt, and motors are mounted on the front and rear ends of the moving plate via motor mounts. The motors are coaxially connected to the corresponding end of the transmission rollers via couplings.

[0015] Furthermore, an inverted T-shaped buffer strip is fixedly connected to the front side of the limiting strip.

[0016] Compared with the prior art, the present invention has the following advantages: 1. Achieve non-destructive, high-strength composite of vacuum insulation board and rock wool board: By rolling and pressing, air bubbles in the bonding mortar are expelled while avoiding impact or vibration, effectively protecting the integrity of the vacuum core material and ensuring the bonding strength and thermal performance of the composite interface are stable.

[0017] 2. Integrated automated positioning and adaptive clamping functions: The stacking mechanism can automatically adapt to different width plates and pressure holding fixtures through hydraulic linkage and universal ball support. With the help of the limit linkage mechanism, it can achieve millimeter-level precise alignment and eliminate misalignment and hollow areas.

[0018] 3. Improve operational safety and production efficiency: During the pressing process, negative pressure is simultaneously applied to absorb rock wool fiber debris, reducing the risk of dust exposure; the pressure holding fixture adopts a quick-installation X-type telescopic frame and industrial buckles, which are easy to install and disassemble, support continuous flow maintenance, and significantly improve the production line cycle time and finished product consistency.

Detailed Implementation

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] like Figures 1 to 12 As shown, this embodiment provides a composite production process for an AA structure composite insulation board, including the following steps: S1. Precast Class A fireproof insulation board: Using reinforcing ribs 403 as the internal reinforcing skeleton, special structural adhesive is evenly coated on the left and right sides of the reinforcing ribs 403, and two rock wool boards 402 are symmetrically bonded to the two sides of the reinforcing ribs 403. After preliminary curing, a Class A fireproof insulation board with an internal reinforcing skeleton is formed. The built-in reinforcing ribs 403 improve the overall bending strength and dimensional stability of the rock wool boards 402, avoid deformation or cracking of large-sized boards during handling or pasting, and ensure uniform stress on the structural adhesive, thus improving bonding reliability.

[0034] S2. Precise stacking: Apply adhesive mortar to the upper surface of the vacuum thermal insulation composite insulation board 401, and precisely align and stack the Class A fireproof insulation board on top of the vacuum thermal insulation composite insulation board 401 using the stacking mechanism 10 of the special composite equipment, ensuring that the edges of the two are aligned and the adhesive surfaces are completely covered; avoid local hollow areas or stress concentration caused by misalignment, and ensure the overall flatness and thermal performance continuity of the composite board.

[0035] S3. Non-destructive pressing and bonding: The pressing mechanism 20 of the bonding equipment applies uniform and controllable vertical pressure, so that the Class A fireproof insulation board and the vacuum insulation composite insulation board 401 are tightly bonded and initially bonded without damaging the vacuum insulation core material, thus obtaining the AA structure composite insulation board process component; while protecting the core function (vacuum degree) of the vacuum insulation composite insulation board 401 from damage, air bubbles in the bonding mortar are expelled, and the interface bonding strength is improved.

[0036] S4. Shaping and Pressure Curing: The AA-structured composite insulation board component is placed into the pressure-holding fixture 30 and cured under constant pressure and standard temperature and humidity to allow the bonding mortar to fully solidify and form a stable bonding interface; to prevent interlayer displacement due to its own weight or environmental disturbance during the curing process, and to ensure that the mechanical properties of the bonding interface meet the standards.

[0037] S5. Demolding and Output of Finished Product: After curing, release the constraints of the pressure-holding fixture 30, remove the molded AA-structure composite insulation board 40, and complete the production process. This achieves efficient and non-destructive demolding, ensuring the appearance quality and structural integrity of the finished product.

[0038] Furthermore, in step S4, the curing time is 2-24 hours, the temperature is 10-35℃, and the relative humidity is 40-70%. This temperature and humidity range takes into account both the hydration reaction rate of the cement-based bonding mortar and the feasibility of on-site construction, avoiding high-temperature cracking or low-temperature slow setting, and ensuring that the bonding strength reaches the design requirements within a reasonable period.

[0039] In this embodiment, the stacking mechanism 10 includes a support frame 101. A plurality of support feet 102 are evenly distributed at the bottom of the support frame 101. Two rows of inverted L-shaped support frames 103 are symmetrically arranged at the top of the support frame 101. A universal ball joint 104 is mounted on the top of each support frame 103. A linear guide rail 105 is horizontally fixed to the upper side of each support frame 103. A guide rail slider 106 is slidably fitted on the linear guide rail 105. All guide rail sliders 106 located on the same side are connected to a moving plate 107. The moving plate 107... The upper part is supported by multiple conveying rollers 108 that rotate laterally, and the lower part is fixedly connected to multiple clamping tubes 113 along the lateral direction. The middle part of the support frame 101 is provided with a support plate 114 horizontally. The upper side of the support plate 114 is vertically connected to a hydraulic cylinder 115, and its piston rod is connected upward to a lifting plate 116. The two sides of the lifting plate 116 are symmetrically connected to hinge seats 117, and the lower sides of the two moving plates 107 are respectively connected to hinge seats 118. The hinge seats 117 and the hinge seats 118 on the same side are hinged together by hinge strips 119. Support feet 102 provide stable support for the whole machine; universal balls 104 are used to support the pressure holding fixture 30; hydraulic cylinders 115 drive lifting plates 116 and link the moving plates 107 on both sides through hinge bars 119, so that the two rows of conveyor rollers 108 can be synchronously retracted or expanded, thereby realizing adaptive clamping and precise positioning of plates of different widths and pressure holding fixtures 30, significantly improving the equipment's versatility, stacking accuracy and operational stability.

[0040] In this embodiment, the pressing mechanism 20 includes a pair of rodless cylinders 201, which are respectively installed on the upper part of the two side movable plates 107. The slider of each rodless cylinder 201 is vertically connected to a moving bar 202. A fixed plate 203 is provided between the two moving bars 202. The two sides of the fixed plate 203 are vertically connected to guide posts 204. The guide posts 204 are slidably engaged with the moving bar 202 on the same side through guide sleeves 205. A helical spring 206 is sleeved on the guide post 204. A double-axis cylinder 207 is vertically installed on the fixed plate 203. Its piston rod is connected downward to a lifting bar 208. The lower part of the lifting bar 208 is connected to a mounting shell 209 with a bottom opening. A pressing roller 210 is rotatably installed in the mounting shell 209. A suction pipe 211 is symmetrically connected to its upper side. The rodless cylinder 201 provides long-stroke, high-rigidity lateral synchronous adjustment capability, adapting to composite insulation boards of different widths; the dual-axis cylinder 207 drives the pressing roller 210 to press vertically downwards, achieving controllable and gentle contact pressure to avoid impact damage to the vacuum insulation core material; the helical spring 206 ensures that the fixed plate 203 is always at the symmetrical center position of the two moving strips 202, even when the moving plates 107 move closer or further apart due to the adjustment of the board width, the pressing roller 210 can still maintain the center alignment, ensuring uniform pressing; the suction pipe 211 is connected to an external negative pressure source, which can adsorb floating dust on the board surface, such as fiber debris falling off the surface of the rock wool board 402, during pressing, ensuring a clean environment; the pressing roller 210 adopts a rolling contact method, which can roll slightly with the board surface during the pressing process, effectively dispersing local stress, preventing indentations or core material damage, and achieving a "uniform, damage-free, and efficient" composite compaction effect.

[0041] In this embodiment, the pressure-holding fixture 30 includes a placement frame 301 and a telescopic frame 303 disposed above the placement frame 301. Positioning plates 302 are symmetrically arranged at the front and rear ends of the placement frame 301. The telescopic frame 303 is composed of multiple X-shaped telescopic joints 304 that are sequentially hinged together. A lower pressure bar 305 is connected below the central hinge point of each telescopic joint 304. Side pressure rollers 306 are respectively hinged to the lower ends of its four overhanging ends. The two ends of the lower pressure bar 305 are detachably connected to the placement frame 301 through industrial fasteners 307. Multiple notches 107a are spaced laterally along the moving plate 107. A lifting ring 308 is connected above the central hinge point of each telescopic joint 304. The X-type telescopic frame 303, based on the geometric deformation characteristics of the linkage mechanism, can adaptively adjust the clamping force within a certain thickness tolerance range to ensure that a uniform and stable pressure-holding load is applied to AA structure composite insulation boards 40 of different batches or specifications. The lower pressure strip 305 is used to uniformly transfer the upper pressure to the top surface of the board, while the side pressure rollers 306 apply lateral restraint force to the side of the board, effectively suppressing warping deformation caused by mortar shrinkage or temperature and humidity changes during the curing process. The industrial fastener 307 realizes quick locking and unlocking between the placement frame 301 and the telescopic frame 303, significantly improving clamping efficiency and suitable for batch continuous production. The lifting ring 308 facilitates the overall handling of the pressure-holding fixture 30 by forklifts or lifting equipment, while the notch 107a provides clearance for operating the industrial fastener 307.

[0042] Furthermore, all the conveyor rollers 108 located on the same side are connected by a conveyor belt 109. Motors 111 are mounted on the front and rear ends of the moving plate 107 via motor mounts 110. The motors 111 are coaxially connected to the corresponding end of the conveyor roller 108 via couplings 112. Since both the vacuum insulation composite insulation board 401 and the Class A fireproof insulation board are lightweight porous materials with low weight and low frictional resistance, they are difficult to stably transport to the rear station of the conveyor roller 108 by inertia. Therefore, the motors 111 actively drive the conveyor roller 108 to rotate, achieving precise, continuous, and controllable feeding of the boards.

[0043] Furthermore, a first conveyor line 120 is provided in front of the two rows of drive rollers 108, and a second conveyor line 121 is provided in front of the two rows of universal balls 104. The first conveyor line 120 is used to convey the vacuum insulation composite insulation board 401 and the Class A fireproof insulation board coated with adhesive mortar backward to the space between the two rows of drive rollers 108, and the second conveyor line 121 is used to convey the lower half of the unloaded pressure holding fixture 30 backward to the space between the two rows of universal balls 104.

[0044] Furthermore, each of the movable plates 107 is fixedly connected to a fixed strip 122 at its rear end. The upper end of the fixed strip 122 is hinged to a movable strip 123, and the lower ends of the movable strips 123 on both sides are hinged to a herringbone-shaped limiting strip 124. When the two movable plates 107 move towards each other and retract inward, the limiting strip 124 is driven to swing downward to a low position through the linkage between the fixed strip 122 and the movable strip 123. At this time, a transverse stop surface is formed at the bottom of the limiting strip 124, which is used to limit the forward limit position of the pressure holding fixture 30, the vacuum thermal insulation composite insulation board 401 coated with adhesive mortar, and the Class A fireproof insulation board at the stacking position, ensuring that the three are accurately aligned and within the effective working range of the pressing mechanism 20. When the two movable plates 107 move in opposite directions and unfold outwards, the limit bar 124 is lifted to a high position by the linkage mechanism, thereby avoiding the rear passage. At this time, the limit bar 124 no longer constitutes an obstacle, so that the pressure holding fixture 30 can smoothly exit backwards or enter the next process, ensuring the continuity of the production line and the efficiency of automated flow.

[0045] Furthermore, an inverted T-shaped buffer strip 125 is fixedly connected to the front side of the limiting strip 124. The buffer strip 125 is made of an elastic material (such as polyurethane). When the pressure holding fixture 30 moves to its limit position and comes into contact with the limiting strip 124, the buffer strip 125 absorbs the impact energy through elastic deformation, effectively reducing collision noise and preventing direct impact of metal parts, thereby protecting the equipment structure and extending its service life.

[0046] The working principle of a composite equipment for AA structure composite insulation boards is as follows: 1. Tooling Positioning Stage First, the hydraulic cylinder 115 is activated, its piston rod extends upward, pushing the lifting plate 116 to rise. Through the linkage of the hinge bars 119 on both sides, the moving plates 107 on both sides are driven to expand outward synchronously along the linear guide rail 105. Then, the second conveyor line 121 automatically transports the unloaded lower half of the pressure holding fixture 30 (i.e., the placement frame 301 and the front and rear positioning plates 302) above the two rows of universal balls 104. Next, the hydraulic cylinder 115 retracts, the lifting plate 116 descends, and through the hinge bars 119, the moving plates 107 on both sides are driven to retract inward synchronously, so that the clamping tubes 113 on both sides can adaptively center and clamp the placement frame 301.

[0047] 2. Panel Laying Stage Meanwhile, conveyor line 120 sequentially transports the vacuum insulation composite insulation board 401 coated with adhesive mortar 405 and the prefabricated Class A fireproof insulation board, consisting of rock wool board 402 and reinforcing ribs 403, to above the two rows of conveyor rollers 108. Subsequently, hydraulic cylinder 115 pushes the moving plates 107 on both sides to unfold outwards simultaneously, allowing the vacuum insulation composite insulation board 401 and the Class A fireproof insulation board to fall smoothly and sequentially above the placement frame 301, completing precise stacking.

[0048] 3. Non-destructive pressing composite stage After the components are aligned, the pressing mechanism 20 is activated: the piston rod of the dual-axis cylinder 207 extends downward, sequentially driving the lifting bar 208, the mounting shell 209, and the internal pressing roller 210 to slowly descend. During this process: the pressing roller 211 applies uniform and controllable vertical pressure in a rolling contact manner; the suction pipe 211 is simultaneously connected to a negative pressure source to adsorb dust on the board surface and any fiber debris that may fall off the rock wool board 402, ensuring a clean bonding interface; the entire pressing process does not generate impact or vibration, effectively protecting the integrity of the vacuum core material of the vacuum insulation composite insulation board 401, while simultaneously expelling air bubbles from the adhesive mortar 405, achieving tight bonding and initial adhesion, forming the AA structure composite insulation board component.

[0049] 4. Tooling Assembly Stage After the pressing and bonding process is completed, the operator places the telescopic frame 303 over the AA-structure composite insulation board from above, and locks the lower pressure strips 305 to the placement frame 301 using industrial fasteners 307, completing the rapid assembly of the pressure-holding fixture 30. In this state, each lower pressure strip 305 uniformly transfers the vertical load to the top surface of the composite board, while each side pressure roller 306 flexibly adheres to the side edge of the board, applying lateral restraint force. This effectively suppresses warping deformation of the adhesive mortar 405 during the curing process caused by shrinkage or temperature and humidity changes, ensuring the flatness and dimensional stability of the finished product.

[0050] 5. Tooling removal stage Subsequently, the hydraulic cylinder 115 pushes the two side moving plates 107 to unfold outward again, and the limiting strip 124 is raised to the high position, releasing the forward obstruction. At this time, the entire pressure holding fixture 30, carrying the AA structure composite insulation board workpiece, can smoothly slide backward along the universal ball 104 to the curing station.

[0051] 6. Pressure Holding and Curing Stage At the curing station, the pressure-holding fixture 30, along with the AA structural composite insulation board components, is left to cure under standard environmental conditions of 10-35℃ and 40%-70% relative humidity for 2-24 hours. During this period, the bonding mortar 405 is fully hydrated and forms a high-strength, stable bonding interface.

[0052] 7. Demolding and Finished Product Output After the curing is completed, loosen the industrial buckle 307, remove the telescopic frame 303, and the formed AA structure composite insulation board 40 can be taken out from the placement frame 301 to complete the finished product output.

[0053] Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not exhaustive. All modifications within the scope of this invention or its equivalents are included in this invention.
