Description

Technical Field

[0001] This invention relates to the technical field of thermal insulation materials, specifically to a production process and equipment for reinforcing ribs in AA structure composite thermal insulation boards. Background Technology

[0002] In the field of building energy conservation, AA structural composite insulation boards are widely used due to their excellent thermal insulation performance. They are usually embedded with lightweight and high-strength reinforcing ribs to improve the overall bending and shear resistance.

[0003] Existing reinforcing ribs mostly use ordinary cement-based materials or single fiber reinforced structures, which have problems such as high density, high thermal conductivity, and easy formation of thermal bridges, making it difficult to meet the requirements of green buildings for "low energy consumption and high durability".

[0004] Meanwhile, the production of reinforcing ribs generally employs single-rib casting or cutting methods, which are inefficient. After cutting, multiple products are closely attached, making side surface cleaning difficult, and residual dust affects subsequent bonding or assembly quality. In addition, during high-speed dry cutting, the cutting tool is prone to heating due to friction, causing polystyrene particles to melt and stick to the tool, and glass fibers to break and scatter, which not only reduces cutting accuracy but also accelerates tool wear and pollutes the working environment.

[0005] Existing equipment lacks an integrated solution that combines precise cutting, automatic separation, synchronous cleaning, and tool cooling, making it difficult to achieve high-quality, high-efficiency, and green mass production.

[0006] Therefore, there is an urgent need for a new process and equipment for manufacturing reinforcing ribs that integrates material formulation with intelligent production equipment optimization. Summary of the Invention

[0007] The purpose of this invention is to provide a production process and equipment for reinforcing ribs in AA structural composite insulation boards, so as to solve the problems in the prior art such as poor thermal performance of reinforcing rib materials, low cutting efficiency, difficulty in cleaning due to multiple reinforcing ribs being close together, easy wear of cutting tools, and harsh working environment.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A manufacturing process for reinforcing ribs in AA structural composite insulation boards includes the following steps: S1: Ingredient Preparation Weigh the following raw materials by weight: 280-320 parts gray silicate cement, 0.8-1.2 parts concrete water-soluble fiber, 45-50 parts non-woven fabric, 1.5-2.5 parts microcrystalline nucleated early-strength cement, 7-9 parts polystyrene particles, 1.5-2.5 parts glass fiber, 1.5-2.5 parts reinforcing agent, 0.8-1.2 parts foaming agent, and 0.4-0.6 parts cellulose; also prepare 85-95 meters of glass fiber mesh. S2: Slurry Preparation The gray silicate cement, concrete water-soluble fiber, microcrystalline nucleated early-strength cement, polystyrene particles, reinforcing agent and cellulose are put into a mixing tank and dry-mixed for 3-5 minutes; then 35%-45% of the total solid phase mass of mixing water is added and the mixture is stirred for 8-12 minutes to form a uniform slurry; then the glass fiber and foaming agent are added and stirred at low speed for 2-3 minutes to obtain a lightweight composite slurry. S3: Multi-layer composite molding In a long strip mold, a bottom layer of nonwoven fabric and a first layer of glass fiber mesh are laid from bottom to top; a portion of the lightweight composite slurry is injected, and after vibration to compact it, the surface is smoothed; then a second layer of glass fiber mesh and a top layer of nonwoven fabric are laid in sequence, and the remaining slurry is injected to fill the top of the mold, and after vibration to compact it again, the surface is smoothed to form a multi-layer composite preform with an upper and lower nonwoven fabric-mesh sandwich structure; S4: Phased Maintenance The mold is placed in a curing environment with a temperature of 20-30℃ and a relative humidity of ≥90% and left to cure for 24-48 hours. When the compressive strength of the preform reaches 60%-70% of the design strength, it is demolded to obtain a semi-finished board. The semi-finished board is then transferred to a standard curing room and cured at a temperature of 20±2℃ and a relative humidity of ≥95% until it reaches the design strength. S5: Precision cutting and slitting Using specialized production equipment, the semi-finished sheet material is cut into multiple finished reinforcing ribs of the same size at a preset interval along its length, and simultaneously cleaned.

[0009] A dedicated production equipment for the aforementioned production process includes a collection tank, a cutting mechanism, a pair of dispersing mechanisms, and a cleaning mechanism. The collection pool is used to collect dust particles, debris, and dirty water generated during the cutting process; The cutting mechanism is located above the collection pool and includes a rodless cylinder, a motor, and a cutting blade assembly. The motor drives the cutting blade assembly to cut the semi-finished sheet material, and the rodless cylinder drives the cutting blade assembly to move along the length of the semi-finished sheet material, thereby simultaneously cutting out multiple reinforcing ribs of the same size at one time. A pair of the dispersion mechanisms are symmetrically arranged inside the collection pool. Each dispersion mechanism includes a biaxial cylinder and a plurality of dispersion strips arranged in a transverse direction. The biaxial cylinder drives the dispersion strips to be supported below each of the reinforcing ribs and to expand synchronously in a transverse direction so that a uniform gap is formed between adjacent reinforcing ribs. The cleaning mechanism is located above the collection pool and includes a dual-axis cylinder and multiple cleaning rollers arranged laterally. The dual-axis cylinder drives the cleaning rollers to be in contact with the sides of each reinforcing rib. The rodless cylinder then drives the cleaning rollers to move along the length of the reinforcing ribs to remove dust particles, debris and dirty water adhering to the surface of the reinforcing ribs.

A second pulley is installed at the end of the rotating shaft, and the first pulley and the second pulley are connected by a transmission belt.

[0011] Furthermore, the cutting blade assembly includes a pair of flange seats symmetrically sleeved on the rotating shaft. Each flange seat is locked and fixed to the rotating shaft by a set screw. The two flange seats are connected by multiple threaded rods evenly distributed circumferentially. Multiple cutting blades are sequentially mounted on the threaded rods, and a separator ring is coaxially provided between two adjacent cutting blades.

[0012] Furthermore, a protective cover is provided above the cutting blade assembly, and connecting strips are symmetrically connected to both sides of the protective cover, with a guide post two vertically fixed on each connecting strip; The two sides of the longitudinal frame are symmetrically connected with connecting pieces, and each of the guide posts 2 slides with the corresponding connecting piece through the guide sleeve 2.

[0013] Preferably, one of the pair of twin-shaft cylinders is vertically mounted on the inner side of the collection tank via a fixing plate; The piston rod of the first dual-axis cylinder extends upward and is connected to a movable plate. A movable frame is provided above the movable plate, and a guide rod is fixed parallel inside the movable frame. A pair of sliding bars are slidably fitted on the guide rod, and a compression spring is provided between each sliding bar and the movable frame. A hinge seat is installed on the lower side of each sliding bar. The upper side of the movable plate is symmetrically provided with hinge seat two, and the hinge seat one and the corresponding hinge seat two are hingedly connected by a hinge strip. The movable plate is symmetrically provided with limiting strips on both sides, and each limiting strip is connected to the corresponding hinge strip by a compression spring. Multiple dispersion strips are arranged laterally and slidably connected between two of the aforementioned sliding strips. Each dispersion strip has a limiting plate symmetrically connected to both sides. The limiting plate is provided with multiple through grooves, and a spring sheet is connected between two adjacent dispersion strips.

[0014] Preferably, the pair of dual-axis cylinders are mounted on the transverse frame via a fixing frame; The piston rod of the dual-axis cylinder 2 extends upward and is connected to a lifting plate. A mounting plate is provided below the lifting plate. Guide pillars 3 are symmetrically fixed on the mounting plate. Each guide pillar 3 slides with the lifting plate through a guide sleeve 3. A compression spring 3 is sleeved on each guide pillar 3. A water collection pipe is horizontally fixed on the lower side of the mounting plate. Multiple water spray pipes are evenly connected to the lower side of the water collection pipe along the axial direction. Multiple water spray holes are provided on the side of each water spray pipe. A water inlet pipe is connected to the end of the water collection pipe. The mounting plate is supported by multiple mounting shafts that rotate laterally, and the lower end of each mounting shaft is coaxially connected to a cleaning roller. Multiple mounting rods are fixedly connected to the horizontal side of the lifting plate, and a water squeezing ring is connected to the lower end of each mounting rod. The water squeezing ring is sleeved on the outer periphery of the corresponding cleaning roller.

[0015] Furthermore, the inner side of the collection pool is provided with multiple conveyor belts arranged at intervals and flush with each other. The outer wall of each conveyor belt is provided with multiple annular blade avoidance grooves evenly distributed along the circumference.

[0016] Furthermore, the protective cover is provided with multiple cooling pipes on its side, and the outlet of each cooling pipe corresponds one-to-one with the blade area of ​​the cutting blade assembly.

[0017] Compared with the prior art, the present invention has the following advantages: 1. Material-structure-process synergistic optimization to achieve lightweight, high-strength and low thermal bridge: Through the scientific proportion and sandwich structure design of gray silicate cement, microcrystalline nucleus early-strength cement, polystyrene particles and double-layer glass fiber mesh, the density (≤800 kg / m³) and thermal conductivity are significantly reduced while ensuring compressive strength, effectively suppressing the thermal bridge effect and improving the overall energy efficiency of the insulation board.

[0018] 2. One-time multi-rib precision cutting, improving both efficiency and accuracy: The modular adjustable-distance cutting blade set, combined with rodless cylinder feeding and hydraulic height adjustment, enables the simultaneous cutting of multiple reinforcing ribs in a single stroke, with a width tolerance of ≤±0.5 mm, increasing production efficiency by more than 3 times.

[0019] 3. The entire process of cutting, dispersing, and cleaning is automated, eliminating cleaning dead corners: The dispersing mechanism immediately expands laterally after cutting, forcibly forming uniform gaps; the cleaning mechanism simultaneously sprays, rolls and wipes, and squeezes water for self-cleaning, ensuring that the side surface of each reinforcing rib is free of dust, water stains, and scratches, achieving an industrial-grade cleanliness standard.

Detailed Implementation

[0033] 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.

[0034] This embodiment provides a manufacturing process for reinforcing ribs in AA structural composite insulation boards, including the following steps: S1: Ingredient Preparation Weigh the following raw materials by weight: 280-320 parts gray silicate cement, 0.8-1.2 parts concrete water-soluble fiber, 45-50 parts non-woven fabric, 1.5-2.5 parts microcrystalline nucleated early-strength cement, 7-9 parts polystyrene particles, 1.5-2.5 parts glass fiber, 1.5-2.5 parts reinforcing agent, 0.8-1.2 parts foaming agent, and 0.4-0.6 parts cellulose; also prepare 85-95 meters of glass fiber mesh. S2: Slurry Preparation The gray silicate cement, concrete water-soluble fiber, microcrystalline nucleated early-strength cement, polystyrene particles, reinforcing agent and cellulose are put into a mixing tank and dry-mixed for 3-5 minutes; then 35%-45% of the total solid phase mass of mixing water is added and the mixture is stirred for 8-12 minutes to form a uniform slurry; then the glass fiber and foaming agent are added and stirred at low speed for 2-3 minutes to obtain a lightweight composite slurry. S3: Multi-layer composite molding In a long strip mold, a bottom layer of nonwoven fabric and a first layer of glass fiber mesh are laid from bottom to top; a portion of the lightweight composite slurry is injected, and after vibration to compact it, the surface is smoothed; then a second layer of glass fiber mesh and a top layer of nonwoven fabric are laid in sequence, and the remaining slurry is injected to fill the top of the mold, and after vibration to compact it again, the surface is smoothed to form a multi-layer composite preform with an upper and lower nonwoven fabric-mesh sandwich structure; S4: Phased Maintenance The mold is placed in a curing environment with a temperature of 20-30℃ and a relative humidity of ≥90% and left to cure for 24-48 hours. When the compressive strength of the preform reaches 60%-70% of the design strength, it is demolded to obtain a semi-finished board 50. The semi-finished board 50 is then transferred to a standard curing room and cured at a temperature of 20±2℃ and a relative humidity of ≥95% until it reaches the design strength. S5: Precision cutting and slitting Using specialized production equipment, multiple finished reinforcing ribs 60 of the same size are cut along the length of the semi-finished sheet 50 at a preset interval in one go, and they are cleaned simultaneously.

[0035] This process, through scientific proportioning and layered composite structure design, enables the reinforcing rib 60 to significantly reduce density while ensuring compressive strength and reducing thermal bridging effect; the phased curing system takes into account both demolding efficiency and final strength development, ensuring product dimensional stability and mechanical properties meet standards.

[0036] This embodiment also provides a special production equipment for the production process, including a collection tank 10, a cutting mechanism 20, a pair of dispersing mechanisms 30 and a cleaning mechanism 40; The collection pool 10 is used to collect dust particles, debris and dirty water generated during the cutting process; By setting up collection pool 10 to centrally collect and process pollutants, dust diffusion is avoided, the working environment is improved, and waste disposal is facilitated, which meets the requirements of green manufacturing.

[0037] The cutting mechanism 20 is disposed above the collection pool 10 and includes a rodless cylinder 201, a motor 208, and a cutting blade assembly 213. The motor 208 drives the cutting blade assembly 213 to cut the semi-finished sheet 50, and the rodless cylinder 201 drives the cutting blade assembly 213 to move along the length of the semi-finished sheet 50, so as to simultaneously cut out multiple reinforcing ribs 60 of the same size at one time. This structure enables multi-blade synchronous feed cutting, which greatly improves production efficiency. The fixed blade spacing ensures that the width of each reinforcing rib is consistent, meeting the assembly accuracy requirements of AA insulation boards.

[0038] A pair of the dispersion mechanisms 30 are symmetrically arranged on the inner side of the collection pool 10. Each dispersion mechanism 30 includes a biaxial cylinder 302 and a plurality of dispersion strips 313 arranged in the transverse direction. The biaxial cylinder 302 drives the dispersion strips 313 to be supported below each of the reinforcing ribs 60 and to expand synchronously in the transverse direction so that a uniform gap is formed between adjacent reinforcing ribs 60. This structure can automatically separate the side-by-side reinforcing ribs 60 immediately after the cutting process, effectively preventing the subsequent cleaning mechanism 40 from being unable to fully contact the side surfaces of each reinforcing rib 60 due to the initial spacing being too small or the ribs being too close to each other. This ensures that the cleaning roller 412 achieves comprehensive and thorough cleaning of the side surfaces of each reinforcing rib 60, significantly improving the cleanliness of the product surface and the reliability of subsequent processes.

[0039] The cleaning mechanism 40 is located above the collection pool 10 and includes a dual-axis cylinder 402 and a plurality of cleaning rollers 412 arranged laterally. The dual-axis cylinder 402 drives the cleaning rollers 412 to be attached to the sides of each of the reinforcing ribs 60, and the rodless cylinder 201 drives the cleaning rollers 412 to move along the length of the reinforcing ribs 60 to remove dust particles, debris and dirty water attached to the surface of the reinforcing ribs 60.

[0040] Through the above structure, the cleaning roller 412, under the synergistic effect of elastic pressing and axial movement, can efficiently remove dust particles, cutting debris and residual moisture adhering to the surface of the reinforcing rib 60. At the same time, the flexible material of the cleaning roller 412 and continuous rolling contact can achieve self-adsorption and self-cleaning effects, avoid secondary transfer of contaminants, ensure that the surface of each reinforcing rib 60 is clean, dry and free of scratches, significantly improve the appearance quality of the product, and provide reliable protection for subsequent packaging, stacking or assembly processes.

[0041] In this embodiment, a pair of rodless cylinders 201 are fixed in parallel on the front and rear sides of the collection pool 10. The sliders of the two rodless cylinders 201 are connected to a transverse frame 202. A hydraulic cylinder 203 is vertically installed in the middle of the transverse frame 202. The piston rod of the hydraulic cylinder 203 extends downward and is connected to a longitudinal frame 204. A guide post 205 is symmetrically connected to the longitudinal frame 204. The guide post 205 slides with the transverse frame 202 through a guide sleeve 206. The motor 208 is fixed to the upper part of the longitudinal frame 204 by the motor base 207, and a pulley 209 is installed on the output shaft of the motor 208; The cutting blade assembly 213 is rotatably supported on the lower part of the longitudinal frame 204 via a rotating shaft 210. A second pulley 211 is installed at the end of the rotating shaft 210. The first pulley 209 and the second pulley 211 are connected by a transmission belt 212.

[0042] This dual-degree-of-freedom drive architecture enables the cutting blade assembly 213 to feed precisely along the length direction and flexibly adjust the cutting depth according to the thickness of the sheet material, adapting to the production of products of different specifications and improving the versatility of the equipment.

[0043] Furthermore, the cutting blade assembly 213 includes a pair of flange seats 2131 symmetrically sleeved on the rotating shaft 210. Each flange seat 2131 is locked and fixed to the rotating shaft 210 by a set screw. The two flange seats 2131 are connected by multiple threaded rods 2132 evenly distributed in the circumferential direction. Multiple cutting blades 2133 are sequentially mounted on the threaded rods 2132. A separator ring 2134 is coaxially provided between two adjacent cutting blades 2133.

[0044] The modular blade assembly structure allows for easy adjustment of the blade spacing 2133 to accommodate different reinforcing rib width requirements. The separator ring 2134 ensures the parallelism of the blades 2133, improving the perpendicularity of the cutting surface and dimensional accuracy.

[0045] Furthermore, a protective cover 214 is provided above the cutting blade assembly 213, and connecting strips 215 are symmetrically connected on both sides of the protective cover 214, with guide posts 216 vertically fixed on each connecting strip 215; The longitudinal frame 204 is symmetrically connected to two sides with connecting pieces 217, and each of the guide posts 216 slides with the corresponding connecting piece 217 through the guide sleeve 218.

[0046] The protective cover 214 can be raised and lowered synchronously with the cutting mechanism 20, completely enclosing the cutting area, effectively blocking dust and debris from splashing, ensuring operational safety, and providing a closed space for cooling and cleaning.

[0047] In this embodiment, a pair of dual-shaft cylinders 302 are vertically mounted on the inner side of the collection pool 10 via a fixing plate 301; The piston rod of the dual-axis cylinder 302 extends upward and is connected to a movable plate 303. A movable frame 304 is provided above the movable plate 303, and a guide rod 305 is fixed in parallel inside the movable frame 304. A pair of sliding bars 306 are slidably fitted on the guide rod 305. A compression spring 307 is provided between each sliding bar 306 and the movable frame 304. A hinge seat 308 is installed on the lower side of each sliding bar 306. The upper side of the movable plate 303 is symmetrically provided with hinge seat 2 309, and the hinge seat 1 308 and the corresponding hinge seat 2 309 are hingedly connected by hinge strip 310. The movable plate 303 is provided with symmetrical limiting strips 311 on both sides, and each limiting strip 311 is connected to the corresponding hinge strip 310 by a compression spring 312. Multiple dispersion strips 313 are arranged laterally and slidably connected between two sliding strips 306. Each dispersion strip 313 has a limiting plate 314 symmetrically connected on both sides. The limiting plate 314 has multiple through grooves 314a. A spring sheet 315 is connected between two adjacent dispersion strips 313.

[0048] This structure can immediately and automatically separate the closely arranged reinforcing ribs 60 to a preset spacing after cutting. When the dispersing strips 313 rise to the support position, the dual-axis cylinder 302 continues to extend, converting the linear motion into the reverse translation of the sliding strip 306 through the hinged linkage mechanism. Combined with the elastic reset action of the spring plate 315, this ensures that each dispersing strip 313 is subjected to balanced force and unfolds uniformly. As a result, a stable and uniform gap is formed between adjacent reinforcing ribs 60, which not only prevents cleaning dead corners caused by close contact, but also provides a reliable spatial reference for subsequent sorting, conveying or stacking, greatly improving the continuous operation capability and product consistency of the automated production line.

[0049] In this embodiment, a pair of dual-axis cylinders 402 are mounted on the transverse frame 202 via a fixing frame 401; The piston rod of the dual-axis cylinder 402 extends upward and is connected to a lifting plate 403. A mounting plate 404 is provided below the lifting plate 403. Guide pillars 405 are symmetrically fixed on the mounting plate 404. Each guide pillar 405 slides with the lifting plate 403 through a guide sleeve 406. A compression spring 407 is sleeved on each guide pillar 405. A water collection pipe 408 is horizontally fixed on the lower side of the mounting plate 404. A plurality of water spray pipes 409 are uniformly connected along the axial direction on the lower side of the water collection pipe 408. A plurality of water spray holes 409a are provided on the side of each water spray pipe 409. A water inlet pipe 410 is connected to the end of the water collection pipe 408. The mounting plate 404 is supported by multiple mounting shafts 411 that rotate laterally, and the lower end of each mounting shaft 411 is coaxially connected to a cleaning roller 412. Multiple mounting rods 413 are fixedly connected to the upper edge of the lifting plate 403 in the horizontal direction. Each mounting rod 413 has a water squeezing ring 414 connected to its lower end. The water squeezing ring 414 is sleeved on the outer periphery of the corresponding cleaning roller 412.

[0050] The dual-axis cylinder 402 drives the water collection pipe 408 to descend above the reinforcing rib 60, and the water spray pipe 409 descends to the side of the reinforcing rib 60. The water spray pipe 409 sprays mist-like water droplets to clean the surface of the reinforcing rib 60. When the cleaning mechanism 40 moves to the right end of the collection tank 10, the dual-axis cylinder 402 drives the mounting plate 404 to abut against the upper edge of the collection tank 10. As the piston rod of the dual-axis cylinder 402 continues to extend, the squeezing ring 414 passes through the cleaning roller 412 from top to bottom, squeezing out dust particles, debris and dirty water on the cleaning roller 412 and letting them fall into the collection tank 10, thus achieving self-cleaning.

[0051] Furthermore, the inner side of the collection pool 10 is provided with a plurality of conveyor belts 101 arranged at intervals and flush with each other. The outer wall of each conveyor belt 101 is provided with a plurality of annular blade avoidance grooves 101a evenly distributed along the circumference. The blade avoidance grooves 101a correspond one-to-one with the blade positions of the cutting blade assembly 213.

[0052] These conveyor belts 101 transport and support the semi-finished sheet 50 and the reinforcing ribs 60. The blade avoidance grooves 101a effectively avoid the high-speed rotating cutting blades 2133, preventing the conveyor belts 101 from being cut and extending their service life. At the same time, they ensure continuous bottom support for the reinforcing ribs 60 and prevent cutting deformation.

[0053] Furthermore, the protective cover 214 is provided with a plurality of cooling pipes 219 on its side, and the outlet of each cooling pipe 219 corresponds one-to-one with the blade area of ​​the cutting blade assembly 213.

[0054] This cooling structure effectively suppresses localized temperature rise caused by friction during cutting, preventing polystyrene particles from softening or melting and adhering to the tool surface, while also reducing the emission of fine dust generated by glass fiber breakage. It not only significantly improves the smoothness and dimensional accuracy of the cutting edge, but also reduces the tool wear rate, extends its service life, and effectively improves the working environment, ensuring the health of operators and production safety.

[0055] The working principle of a production equipment for reinforcing ribs in AA-structure composite insulation boards is as follows: First, the lightweight composite slurry mixed according to the formula is injected into a long strip mold. After multiple layers are laid and vibrated to compact, a multi-layer composite blank is formed. Then, after initial curing and demolding, a semi-finished board 50 is obtained, and it continues to be cured until the design strength is reached.

[0056] During cutting, the semi-finished sheet 50 is placed on the conveyor belt 101 above the collection pool 10. A pair of rodless cylinders 201 drive the transverse frame 202 to move along the length of the sheet, and the hydraulic cylinder 203 adjusts the height of the longitudinal frame 204 to ensure precise positioning of the cutting blade assembly 213. The motor 208 drives the rotating shaft 210 to rotate at high speed through pulley 209, transmission belt 212 and pulley 211, and the cutting blades 2133 rotate synchronously, cutting out multiple reinforcing ribs 60 in one operation.

[0057] After cutting, the dual-axis cylinder 302 drives the movable plate 303 to rise, and pushes the sliding bar 306 to unfold laterally through the hinge bar 310, which drives the dispersing bar 313 to move outward synchronously, so that a uniform gap is formed between each reinforcing rib 60, avoiding the gap being too small, which would result in incomplete cleaning.

[0058] At the same time, the dual-axis cylinder 402 drives the lifting plate 403 to press down, so that the cleaning roller 412 fits against the side of the reinforcing rib 60; the rodless cylinder 201 drives the transverse frame 202 to move back, and the cleaning roller 412 rolls along the length direction. The water spray pipe 409 sprays clean water through the water spray hole 409a, and the water squeezing ring 414 scrapes off the excess water, so as to achieve simultaneous cleaning and drying of dust, debris and dirty water on the surface of the reinforcing rib 60.
