Description

A spout mucilage binding and put for compound aerogel self preservation temperature template

Technical Field

The invention relates to the technical field of heat insulation plate manufacturing, in particular to a glue spraying device for a composite aerogel self-insulation template.

Background

Aerogels, also known as xerogels. When most of the solvent is removed from the gel, the liquid content in the gel is much less than the solid content, or the space network structure of the gel is filled with gas, and the appearance is solid, namely xerogel, also called aerogel. Such as gelatin, gum arabic, silica gel, hair, fingernails, and the like. Aerogels also have the properties of gels, i.e., swelling, thixotropic, de-sizing.

The preparation of the aerogel comprises three stages: one is the preparation of wet gel: the wet gel is prepared by a sol-gel process, and nanoparticles dispersed in a liquid are agglomerated together during the reaction to form a continuous three-dimensional network throughout the solution. Secondly, aging of the wet gel: when the sol reaches the gel point, the silica polymer fills the entire sol-containing vessel. However, there are still many reactive groups on the silicon backbone in the gel that have not yet been reacted. The hydrolysis and condensation reactions may continue and, for a sufficient time, strengthen the silica network. Thirdly, drying the wet gel: drying is the last and most critical step in the aerogel production process, and capillary tension is a critical factor in the overall drying process. The most common drying methods include normal pressure drying and supercritical drying, the normal pressure drying method is simple and convenient in process, but the liquid capillary tension in the pores of the skeleton in the wet gel drying process can cause the shrinkage and even cracking of the gel in the drying process. The supercritical drying method is to discharge the liquid in the skeleton pores under the condition of the critical temperature and the critical pressure of the liquid, and to eliminate the tension of solvent capillary in the drying process, so that the ultra-low density aerogel can be prepared, but the process and the equipment are complex and the cost is high.

The aerogel thermal insulation board, also called composite thermal insulation board, is a flexible and high-efficiency thermal insulation material, takes nano-silica aerogel as a main material, and is compounded in inorganic fiber through a special process. The fine nano-mesh structure of the heat insulating material effectively reduces the solid heat conduction of the material, the abundant nano-mesh structure effectively inhibits the convection conduction of gas molecules, and the functional material absorbs and reflects heat radiation, so that the material has extremely low heat conductivity coefficient, and compared with the conventional common heat insulating material, the heat insulating effect can be improved by 2-10 times.

Aerogel insulation board heat insulation principle: when the diameter of the pores in the material is less than 50nm, the air molecules in the pores lose the free flow capacity and are relatively attached to the pore walls, which means that the material is in a nearly vacuum state. Meanwhile, the air holes in the material are all nano-scale air holes, and the material has extremely low volume density, so that the material contains a great number of reflecting interfaces and scattering particles, and the thermal insulation plate is modified in the aspect of heat radiation absorption, so that the aerogel thermal insulation plate has a heat conductivity coefficient lower than that of static air at high temperature and normal temperature.

Traditional wall and roof insulation materials are divided into inorganic materials and organic materials, the organic insulation material polyphenyl foam board occupying 80% of the insulation material market has poor fireproof and flame-retardant properties, and most of inorganic insulation materials such as rock wool and glass wool have large density and poor insulation effect. Aerogel panels have low thermal conductivity, low density, and high flame retardancy, and are ideal insulating materials for walls and roofs.

In conclusion, the aerogel serving as a new solid material with a nano-porous structure has the excellent characteristics of ultralight weight, heat insulation, transparency, fire resistance and the like. The aerogel has great application value in the field of building energy conservation, and can remarkably improve the heat preservation effect and save energy. Along with the research extension and the application expansion in recent years, the application of the aerogel in the building field can improve the energy-saving effect by orders of magnitude.

However, in the production of the existing aerogel board, the glue layer has the important functions of improving the wettability of the surface of the aerogel composite material, bonding the nano-scale particles on the surface of the material together, improving the high temperature resistance and the flame retardancy of the material, and the like, but the glue spraying process in the existing aerogel board is quite backward, the constructors often spray glue and/or glue in the production process, or spray glue by the traditional machine, and the constructors only carry out visual inspection after glue spraying is finished, so that the quality of the glue layer of the aerogel board is uneven, the important functions of high temperature resistance, flame retardancy and the like cannot be ensured, and even the nano-scale particles on the surface of the board are scattered in the construction environment, so that the safety problem caused by suction of the constructors is caused, or the nanometer-scale particles enter a machine to be linked, and the service life of equipment is shortened due to the fact that the gear parts enter. Therefore, how to improve the glue spraying device of the composite aerogel self-insulation template is an urgent problem in the technical field of insulation board manufacturing.

Detailed Description

This is described in detail below with reference to fig. 1-4.

Example 1

As shown in fig. 1, the invention provides a glue spraying device for a composite aerogel self-insulation template, which at least comprises a glue spraying platform 1 and a glue spraying part 2 arranged on the glue spraying platform 1. The glue spraying platform 1 can be used for placing the conveying part 4, so that the composite aerogel felt 19 can be placed on the conveying part 4. When the transmission belt 4 rotates, the composite aerogel felt 19 can be driven to move along the set direction. For example, as shown in FIG. 1, when the conveyor rotates clockwise, the composite aerogel blanket 19 can be entrained to move to the right. Alternatively, the composite aerogel blanket 19 can be driven to the left as the conveyor rotates counterclockwise. The glue spraying part 2 is used for spraying a layer of adhesive with a first set thickness on the surface of the composite aerogel felt, so that a covering layer such as a cement board can be conveniently adhered to the composite aerogel felt. After the covering layer is arranged on the front side and/or the back side of the composite aerogel felt to increase the overall structural strength of the composite aerogel felt, the required composite aerogel self-insulation template can be formed. Preferably, the present invention may further include an adhesive supply mechanism (not shown) used in cooperation with the adhesive spray part 2. The glue supply mechanism may be constituted by a pump and a storage container for storing the adhesive. The storage container is connected to the glue spraying portion via a pump, and the adhesive in the storage container can be sprayed out of the glue spraying portion at a set pressure by the pump.

Preferably, the glue-spraying device further comprises a second placing table 52 and a support 14 defined by an L-shape. The stent 14 includes at least a first strut 14a and a second strut 14 b. The direction of extension of the first strut 14a can be perpendicular to the direction of extension of the second strut 14 b. The first supporting bar 14a can be connected to the second placing table 52 in such a manner that the extending direction thereof is perpendicular to the second placing table 52, so that the extending direction of the second supporting bar 14b can be parallel to the second placing table 52. The glue-spraying portion 2 can be provided on the second support bar 14b so that the outgoing direction of the adhesive sprayed from the glue-spraying portion 2 can be perpendicular to the transmission belt.

Preferably, referring again to fig. 1, a glue application section 15 is provided downstream of the glue injection section 2. The glue application portion 15 is used to apply a layer of adhesive of a second set thickness on the surface of the composite aerogel blanket. The first set thickness may be the same as the second set thickness or may be different from each other. The composite aerogel blanket can be a flexible insulation material formed by compounding silica aerogel, for example, into glass fiber wool, the surface of which is typically porous. The glue spraying part 2 can spray the adhesive to the surface of the composite aerogel felt through set pressure, so that the adhesive can be effectively filled in the pores to achieve the effect of leveling the surface of the composite aerogel felt. Compound aerogel felt spouts gluey processing back rethread rubberizing portion 15 and carries out the rubber coating through spouting gluey portion 2, can reach better surface smoothness under the single rubber coating, and then can reduce the risk of doing over again and mending gluey. The conveying part 4 can drive the composite aerogel felt 19 thereon to move along the first direction by means of rotation so as to enter the working ranges of the glue spraying part 2 and the glue coating part 15 in sequence. The working range is a coverage range in which the adhesive in the glue-spraying portion or the glue-applying portion can be formed.

Preferably, the glue application portion 15 can be provided on the second strut 14b, and the perpendicular distance of the glue application portion 15 from the transmission belt 14 can be increased or decreased. Specifically, the glue spraying platform 1 is further provided with a support plate 16, and the conveying part 4 is arranged on the support plate 16. The shape of the glue platform 1 and the support plate 16 can be defined by a rectangle. Four apex angles of the glue spraying platform 1 are respectively provided with a first push rod motor 17, four apex angles of the supporting plate 16 are respectively connected with the corresponding first push rod motors 17, and then the vertical distance between the gluing part 15 and the conveying part 14 can be increased through the extension of the first push rod motors 17, or the vertical distance between the gluing part 15 and the conveying part 14 can be reduced through the shortening of the first push rod motors 17. For example, as shown in fig. 1, when the first pusher motor 17 is extended, the support plate 16 can be moved upward, so that the vertical distance between the applying section 15 and the transferring section 14 is reduced. The purpose of adjusting the thickness of the adhesive can be achieved by adjusting the vertical distance between the gluing part 15 and the transmission belt 14 through the first push rod motor.

Preferably, as shown in fig. 1 and 2, the glue application portion 15 includes at least a glue application mechanism 15a, a first barrier 15b, and a second barrier 15 c. When the glue coating mechanism 15a abuts against and contacts with the surface of the composite aerogel felt 19 and the composite aerogel felt 19 moves in the first direction under the driving of the conveying part 4, the glue coating mechanism 15a can rotate based on the friction force generated by the abutting contact of the glue coating mechanism and the composite aerogel felt 19, so that the glue coating part can be in a contact state generating rolling friction with the composite aerogel felt, and finally, the adhesive on the glue coating mechanism 15a can be uniformly coated on the surface of the composite aerogel felt 19. As shown in fig. 1, the first direction may be a horizontal right direction. The first blocking body 15b is arranged on a first side 20 of the glue application mechanism 15 a. The second blocking body 15c is arranged on a second side 21 of the gluing mechanism 15a, corresponding to the first side 20 thereof. The lines connecting the first side 20 and the second side 21 can be parallel to each other with the first direction. When the composite aerogel blanket 19 is moved in the first direction such that the glue application mechanism 15a applies glue to the surface of the composite aerogel blanket 19, a first region 19a of the composite aerogel blanket 19 corresponding to the first side 20 can be glued at a first time, and a second region 19b of the composite aerogel blanket 19 corresponding to the second side 21 can be glued at a second time, wherein the first time is later than the second time. For example, as shown in FIG. 1, the first side 20 is located on the right side of the glue mechanism 15a and the second side 21 is located on the left side of the glue mechanism 15a, such that when the composite aerogel blanket 19 is moved horizontally to the right, the second section 19b on the left side of the glue mechanism 15a can be glued earlier than the first section 19a on the right side of the glue mechanism.

Preferably, the first stopper 15b having a flat plate shape is spaced from the glue applying mechanism 15a by a first set distance to form the first passage 22. The second stopper 15c having a flat plate shape and the glue applying mechanism 15a may be spaced apart from each other by a third set distance to form the second passage 23. The first channel 22 can be used for containing the adhesive, so that the adhesive can contact with the circumferential surface of the glue mechanism 15a and be attached to the glue mechanism in the self-rotating process of the glue mechanism 15 a. The residual adhesive left after the glue application attached to the glue application mechanism 15a can enter the second channel 23 for temporary storage and collection. Preferably, as shown in fig. 1, an end portion of the second barrier 15c in a direction perpendicular to the surface of the composite aerogel blanket 19 (i.e., a lower end portion of the second barrier) can be spaced a second set distance from the surface of the composite aerogel blanket 19, and the end portion of the second barrier 15c can be defined by a plane parallel to the surface of the composite aerogel blanket 19, so that in the case where the composite aerogel blanket 19 is moved in the first direction to coat the adhesive of a second set thickness on the surface of the composite aerogel blanket 19, the second barrier 15c can flatten the adhesive by making a relative displacement with the adhesive of the second set thickness to improve the surface flatness thereof. That is, since the lower end portion of the composite aerogel blanket is planar, when the composite aerogel blanket is swept across the surface of the composite aerogel blanket, excess adhesive can be scraped off, and the surface flatness of the adhesive can be improved.

Preferably, again with reference to fig. 1, the glue application means 15a, the first stop 15b and the second stop 15c can be provided on the second strut 14 b. Specifically, the glue applying mechanism 15a at least includes a base 150a, a roller 151a, and a first glue supplier 152 a. The circumferential surface of the glue application mechanism 15a can be defined by the outer surface of the roller body 151 a. The base 150a is disposed on the second leg 14 b. The roller body 151a is rotatably provided on the base 150a in such a manner as to be rotatable about its own central axis. For example, rolling bearings may be provided on both ends of the roller body 151a, fixing holes may be provided on both ends of the base 150a corresponding to both ends of the roller body, respectively, and the rotation of the roller body 151a may be achieved by placing the rolling bearings in the fixing holes. The first glue supplier 152a serves to store the adhesive. The first glue supplier 152a can be disposed on the second strut 14b and can communicate with the first channel 22, thereby allowing the adhesive to enter the first channel 22.

Preferably, at least one elastic brush piece 24 is further arranged on the side of the second barrier 15c close to the gluing mechanism. The resilient brush 24 can be made of a material such as rubber, plastic to give a certain resilience. The elastic brush piece 24 can be brought into abutting contact with the circumferential surface of the roller body 151a to divide the second passage 23 into a first space 23a near the second strut 14b and a second space 23b near the composite aerogel blanket 19. During the rotation of the roller body 151a, the residual adhesive on the roller body can be retained in the second space 23b by the elastic brush piece 24. By providing the second blocking body 15c with the elastic brush piece 24, at least the following technical effects can be achieved: in the prior art, the rear side of the roller body 151a with respect to the advancing direction (i.e., the left side of the roller body 151 a) is in an empty state where the second stopper 15c is not provided, and when the roller body 151a rotates, the residual adhesive on the roller body 151a adheres to the roller body 151a and is brought into the first passage 22 by the rotation of the roller body 151 a. The residual binder is contaminated with debris particles on the surface of the composite aerogel blanket 19 as a result of the residual binder having made contact with the composite aerogel blanket 19. When the contaminated residual adhesive enters the first passage 22 again, it may aggravate the unevenness of the adhesive layer formed by the adhesive on the first region 19a of the composite aerogel blanket, which may easily cause bubbles to form before the cover layer and the adhesive layer when the cover layer is attached to the surface of the composite aerogel blanket, thereby reducing the bonding strength between the cover layer and the composite aerogel. By arranging the elastic brush piece 24, the invention can prevent the residual adhesive from being brought into the first channel 22 by the rotation of the roller body 151a, namely, the residual adhesive can be ensured to be positioned at the left side of the roller body 151a, and further, the first area of the composite aerogel felt 19 can not be influenced. In both cases, the thickness of the glue layer formed by the adhesive on the composite aerogel blanket 19 is usually achieved by adjusting the distance between the roller body 151a and the composite aerogel blanket 19, i.e., in the theoretical case, the thickness of the glue layer is equal to the distance between the roller body and the composite aerogel blanket. Or the thickness of the glue layer can be realized by controlling the supply amount of the adhesive. However, because the roller body 151a has the residual adhesive, the thickness of the adhesive layer is often smaller than the distance between the roller body and the composite aerogel felt, and therefore, in the actual production process, the thickness of the adhesive layer is supplemented by increasing the supply amount of the adhesive, and further, the loss of the adhesive is increased. According to the invention, by arranging the elastic brush piece 24, the residual adhesive on the roller body 151a can be scraped and then coated on the composite aerogel felt again through the second space 23b, so that the problem of reduced adhesive layer thickness caused by residual adhesive on the roller body 151a can be avoided. In addition, the second blocking body 15c can play a role in leveling the adhesive layer on the second area 19b, and the adhesive layer can be ensured to reach the required thickness by adjusting the distance between the second blocking body 15c and the composite aerogel felt. Three, the supply amount of adhesive can be appropriately larger than the amount required to achieve the set glue line thickness, so that part of the adhesive can be buffered in the second space 23 b. Because the composite aerogel felt may have a state of uneven surface, the recessed area needs more adhesive, and the adhesive buffered in the second space 23b can supplement the extra adhesive, so that the flatness of the adhesive layer is further increased.

Example 2

This embodiment is a further improvement of the foregoing embodiment, and repeated contents are not described in detail.

Preferably, the glue spraying device further includes an engaging portion 25, and an external force for urging the roller body 151a to rotate can be applied to the roller body 151a through the engaging portion 25, so as to avoid a sliding friction state in which the roller body 151a does not rotate due to an excessively small friction force between the roller body 151a and the composite aerogel blanket 19. Specifically, the engaging portion 25 includes at least a first engaging body 25a and a second engaging body 25 b. The first engaging body 25a is provided on the roller body 151a, and the second engaging body 25b is provided on the conveying portion 4. Specifically, as shown in fig. 1, the first engaging body 25a may be an external gear. The first engaging body 25a is nestably provided on an end portion of the roller body 151a in the axial direction thereof. The second engaging body 25b can be a rack. The shape of the second engaging body 25b can be defined by a ring shape so that the second engaging body 25b can be nestingly disposed on the conveying portion 4. The outer diameter of the first engaging body 25a can be larger than the diameter of the roller body 151a, so that the first engaging body 25a can come into abutting contact with the second engaging body 25b to assume an engaged state of engagement with each other when the roller body 151a is in abutting contact with the composite aerogel blanket 19. When the composite aerogel blanket 19 is moved in the first direction, the second engaging body 25b can apply an external force in the first direction to the first engaging body 25a based on the engaged state, so that the glue applying mechanism 15a can assume a contact state generating rolling friction with the composite aerogel blanket 19 in response to the external force rotating in the third direction. Specifically, when the composite aerogel felt 19 moves in the first direction, the roller body 151a can rotate counterclockwise, and at the same time, the first engaging body 25a and the second engaging body 25b engage with each other, so that the second engaging body 25b applies an external force in the first direction to the first engaging body 25a, and the first engaging body 25a is further caused to rotate counterclockwise. That is, as shown in fig. 1, the third direction may be a counterclockwise direction. The roller 151a can be prevented from slipping by the engagement of the first engaging body and the second engaging body with each other. For example, when the rotating shaft of the roller body 151a is worn, it may cause an increase in frictional resistance that the roller body 151a needs to overcome to rotate. When frictional resistance increases to being greater than the frictional force between roll body and the compound aerogel felt, roll body 151a will not rotate, is in the slip friction state between roll body 151a and the compound aerogel felt this moment, and the roll body can slide but can not produce the rotation for compound aerogel felt promptly to lead to the glue film that the adhesive formed on compound aerogel felt to appear discontinuous problem. According to the invention, by arranging the meshing part, the second meshing body and the first meshing body are meshed with each other, so that extra external force is provided for the rotation of the roller body, and the rolling friction between the roller body and the composite aerogel felt can be ensured, thereby ensuring the continuity of the glue layer.

Preferably, at least one buffer chamber 27 is provided on the end of the first barrier 15b perpendicular to the first direction and capable of abutting contact with the composite aerogel blanket 19. The vertical distance of the buffer chamber 27 from the roller body 151a can be greater than the vertical distance of the first channel 22 from the roller body 151 a. That is, as shown in FIG. 1, the buffer chamber 27 is located on the right side of the first channel 22. The buffer chamber 27 can be spaced apart from the first passage 22 by a set distance, and thus a partition plate 28 for separating the buffer chamber 27 and the first passage 22 is formed. With the roller body 151a in abutting contact with the composite aerogel blanket 19, the partition plate 28 and the composite aerogel blanket 19 can be spaced a set distance apart to form the connecting passage 29. The buffer chamber 27 can communicate with a second glue supplier 30 provided on the second strut 14b so that the adhesive can enter the buffer chamber 27. Preferably, the first glue supplier 152a may inject the adhesive into the first passage 22 at a first pressure, and the second glue supplier 30 may inject the adhesive into the buffer chamber 27 at a second pressure, wherein the first pressure may be greater than the second pressure, so that the pressure of the first passage 22 may be greater than the pressure of the buffer chamber 27. Preferably, the first and second glue feeders may each be constituted by a pump and a storage container for storing the adhesive. The storage container is connected with the first channel or the buffer cavity through a pump, and the adhesive in the storage container can be conveyed to the first channel or the buffer cavity through the pump at set pressure. Through the above setting mode, can reach following technological effect at least: one, as shown in fig. 1, in the prior art, when the composite aerogel blanket 19 moves to the right to cause the roller body 151a to rotate counterclockwise, the adhesive is accumulated in the first channel 22 on the right side of the roller body 151a, and when the moving speed of the composite aerogel blanket 19 is too high, the replenishing speed of the adhesive may be lower than the consumption speed thereof, so that a negative pressure is formed in the first channel 22, which causes air on the right side of the first channel 22 to enter the first channel 22, and finally, bubbles are generated in the formed adhesive layer. According to the invention, by arranging the buffer cavity 27, the adhesive in the buffer cavity 27 can isolate the adhesive in the first channel from air, so that the adhesive in the first channel 22 can be in an isolated state without contacting with the external environment along the second direction, and finally bubbles can be prevented from being formed in the adhesive layer, and the first direction can be opposite to the second direction. For example, as shown in FIG. 1, when the first direction is horizontal to the right, the second direction is horizontal to the left. In the two methods, when the moving speed of the composite aerogel felt 19 is too fast, the replenishing speed of the adhesive may be less than the consumption speed thereof to generate negative pressure in the first channel, and when the negative pressure is greater than the pressure difference between the first channel and the buffer cavity, the adhesive in the buffer cavity 27 can be promoted to enter the first channel, so that the replenishing speed of the adhesive can be approximately equal to the consumption speed thereof, and the defect of discontinuous adhesive layer can be avoided. Three, the pressure of the first passage 22 can be greater than the pressure of the buffer chamber 27, so that when the consumption speed of the adhesive and the replenishment speed of the adhesive in the first passage are approximately constant, the adhesive in the buffer chamber 27 moves in the first direction and is inhibited from flowing into the first passage 22, that is, the adhesive in the buffer chamber can be prevented from entering the first passage, and even if bubbles exist in the buffer chamber, the bubbles cannot flow into the first passage.

The laser measuring portion 3 may be provided on the second stem 14 b. The laser measuring unit 3 includes at least an emitter 34 and a receiver 35, and when the emitter 34 emits laser light to the surface of the composite aerogel blanket, the receiver 35 can receive scattered light generated by diffuse reflection of the laser light on the surface of the composite aerogel blanket. Preferably, the emitter 34 may be a continuous laser with good monochromaticity, such as: helium neon, argon ion, krypton cadmium and other gas lasers.

Preferably, the data processor 11 may be implemented in hardware, firmware, or as software or computer code storable in a recording medium such as a CD ROM, a RAM, a floppy disk, a hard disk, or a magneto-optical disk, or as computer code originally stored in a remote recording medium or a non-transitory machine-readable medium downloaded through a network and to be stored in a local recording medium, so that the method described herein may be stored in such software processing on a recording medium using a general-purpose computer, a dedicated processor, or programmable or dedicated hardware such as an ASIC or FPGA. It will be appreciated that the computer, processor, microprocessor controller or programmable hardware includes memory components such as RAM, ROM, flash memory, etc. that can store or receive software or computer code that, when accessed and executed by the computer, processor or hardware, implements the processing methods described herein. Further, when a general-purpose computer accesses code for implementing the processes shown herein, execution of the code transforms the general-purpose computer into a special-purpose computer for performing the processes shown herein.

According to a preferred embodiment, the glue-spraying device further comprises at least one placing table 5, the sorting section 12 performing the sorting comprising at least the following steps: the rotation based on conveying portion 4 drives compound aerogel felt and removes along setting for the direction, evenly spouts the glue based on spouting gluey portion 2 to the surface of compound aerogel felt, detects compound aerogel felt based on laser measurement portion 3, and letter sorting portion 12 sorts compound aerogel felt and removes to correspondingly placing on the platform 5 based on detected signal 3.

According to a preferred embodiment, the specific work flow of the glue spraying device at least comprises the following steps:

s1: in the case where the operator places the composite aerogel blanket on the conveying section 4, the composite aerogel blanket moves in a set direction along with the rotation of the conveying section 4, and a layer of adhesive is sprayed on the surface of the composite aerogel blanket through the glue spraying section 2.

S2: the laser measurement unit 3 continuously detects the sprayed composite aerogel felt, and the data processor 11 generates a detection signal 3 based on the detection result.

Specifically, since the detection results generated by the receiver 35 of the laser measuring unit 3 are continuous, the data processor 11 fits the detection result images and averages the detection result images, and the detection signal in the present invention is the average value.

S3: in the case where the data processor 11 generates the first signal 32, the data processor 11 sends a sorting signal that can move the first placing table 51 toward the conveyor 4, so that the composite aerogel that has completed the glue-spraying process can be moved onto the first placing table 51 by the conveyor 4. In the case where the data processor 11 generates the second signal 33, the data processor 11 sends a sorting signal that enables the first placing table 51 to move away from the conveyor 4, so that the composite aerogel that has completed the glue-spraying process can be moved onto the second placing table 52 by the conveyor 4.

S4: in the case where the composite aerogel blanket is moved to the first placing table 51, the user can heat and roll the composite aerogel blanket through the heating roller to form a composite aerogel board.

S2: the laser measuring unit 3 detects the composite aerogel blanket of the thickest gel layer in the standard, and the receiver 35 generates the second light intensity P2.

S3: the laser measuring unit 3 detects the composite aerogel blanket having the thinnest layer of the standard, and the receiving body 35 generates the third light intensity P3.

Preferably, the predetermined value interval P is [ P3/P1, P2/P1 ].

Preferably, the step of generating the preset value interval P is a step of calibrating the thickness of the standard adhesive layer, and the preset value interval P needs to be calibrated again before each production due to the difference in the thickness of the adhesive layer conforming to the aerogel plate caused by different production batches and/or different application fields.

Preferably, the laser light scatters in the glue layer and diffusely reflects as it travels to the composite aerogel blanket surface. Therefore, when the laser is driven into the glue layers with different thicknesses, scattering occurs to different degrees, and the light intensity received by the receiver 35 is correspondingly increased or decreased. I.e. the thicker the glue layer, the less light intensity is detected by the receiver 35. Correspondingly, the thinner the glue layer, the greater the intensity of light detected by the receiver 35.

Preferably, the first detected light intensity P1 can effectively measure the influence of the ambient light and the diffuse reflection of the laser on the surface of the composite aerogel felt on the laser, and the first detected light intensity P1 can be regarded as the light intensity of the diffuse reflection when the composite aerogel felt is not sprayed with glue. Preferably, P3/P1 is the ratio of the light intensity P3 to P1 detected by the receiver after the laser light is scattered in the standard thinnest adhesive layer through diffuse reflection, and P2/P1 is the ratio of the light intensity P2 to P1 detected by the receiver 35 device after the laser light is scattered in the standard thickest adhesive layer through diffuse reflection.

Preferably, the standard thickest glue layer and the standard thinnest glue layer are selected by an operator according to actual production needs.

Preferably, in the production of the existing aerogel plate, the adhesive layer has the important functions of improving the wettability of the surface of the aerogel composite material, bonding the nano-scale particles on the surface of the material together, improving the high temperature resistance and the flame retardance of the material and the like, however, the glue spraying process in the current aerogel plate is quite laggard, the constructors often carry out manual glue spraying and/or gluing in the production process, or spraying glue by a traditional machine, and only carrying out visual observation by constructors to carry out quality inspection after the glue spraying is finished, therefore, the quality of the glue layer of the aerogel plate is uneven, important functions such as high temperature resistance, flame retardance and the like cannot be guaranteed, and even the safety problem that nano-scale particles on the surface of the plate are scattered in the construction environment is caused, so that the safety problem is caused by suction of constructors, or the equipment service life is shortened due to the fact that the nano-scale particles enter a machine link and gear parts.

According to a preferred embodiment, the sorting section 12 is provided with a second pusher motor 13, the placing table 5 comprises at least a first placing table 51 and a second placing table 52, the second pusher motor 13 being connected to the first placing table 51.

According to a preferred embodiment, the user can heat and roll the composite aerogel blanket through the heating roller when the composite aerogel blanket moves to the first placing table 51, and can perform manual spray correction on the composite aerogel when the composite aerogel blanket moves to the second placing table 52.

Preferably, the sorting part 12 comprises at least a second push rod motor 13, the second push rod motor 13 being able to be arranged on the support 14. The second placing table 25 can be provided on the second pusher motor 13, wherein the composite aerogel felt 19 can be moved to the first placing table 51 or the second placing table 52 based on the sorting by the sorting section 12. Specifically, in the case where the data processor 11 generates the first signal 32, the composite aerogel blanket can be moved onto the first placing table 51 in a manner carried along by the conveying section 4. In the case where the data processor 11 generates the second signal 33 and generates the sorting signal, the sorting section 12 shortens the second pusher motor 13 in such a manner as to receive the sorting signal, thereby bringing the first placing table 51 away from the conveying section 4, and in the case where the first placing table 51 is away from the conveying section 4, the composite aerogel blanket can be moved onto the second placing table 52 in such a manner as to be brought along by the conveying section 4. Alternatively, the composite aerogel blankets can be sorted by manually controlling the extension and contraction of the second push rod motor. That is, when the second pusher motor is manually controlled to be elongated, the composite aerogel blanket on the conveying portion can drop on the first placing table 51. When the second pusher motor is manually controlled to be shortened, the composite aerogel blanket on the conveying portion can drop on the second placing table 52.

Preferably, the present invention effectively improves the sorting efficiency by providing the sorting part 12 and the second push rod motor 13 in cooperation, and adjusts the position of the first placing table 51 by the extension and contraction of the second push rod motor 13, so as to achieve the purpose of sorting and moving the composite aerogel felt onto the corresponding placing table 5. Preferably, the sorting section 12 operates on a principle similar to a servomotor.

Preferably, the thickness of the glue layer made of a material such as gel cannot be effectively measured by the conventional photoelectric detection device, and the loss of light intensity caused by light scattering in the glue layer is non-linearly changed along with the change of the thickness of the glue layer, so that quantitative calculation cannot be performed. The invention obtains the preset value interval P, namely [ P3/P1, P2/P1] by measuring the light intensity P2 reflected by two ends of the standard glue layer thickness interval, namely the thickest glue layer, and the light intensity P3 reflected by two ends of the standard thinnest interval, namely the thinnest glue layer. Therefore, the adhesive layer of the composite aerogel plate in actual production can be measured and compared with P1, and if the detected value is in a preset value interval P, the composite aerogel plate is qualified, otherwise, the composite aerogel plate is unqualified. According to the method, the qualitative calculation of the measured thickness is skillfully converted into the qualitative calculation of whether the measurement belongs to the preset numerical value interval P, so that the direct calculation of the thickness of the adhesive layer of the aerogel plate is effectively avoided, and the accuracy of the detection result is greatly improved.

Preferably, the steps described in this application can be divided into more steps according to the implementation requirement, and two or more steps or partial operations of the steps can be combined into a new step to achieve the purpose of the invention. Meanwhile, each functional unit described in this application may be split into more functional units, or two or more functional units or a part of functions of a functional unit may be combined into a new functional unit, so as to achieve the purpose of the present invention.

It should be understood by those skilled in the art that the present specification and figures are illustrative only and are not limiting upon the claims.
