Description

Technical Field

[0001] This invention relates to the field of LNG ship containment systems, specifically to a main layer bridging plate adhesive coating device and adhesive coating method. Background Technology

[0002] Currently, some LNG carriers, LNG bunkering vessels, and LNG-powered ships use Mark III membrane-type containment systems in their fuel tanks. Mark III membrane-type containment systems typically consist of a secondary insulation layer, a secondary shield, a primary insulation layer, and a primary shield. During fabrication, the primary insulation layer is prefabricated on the secondary insulation layer. The secondary shield includes rigid and flexible secondary shields, with the rigid secondary shield prefabricated between the primary and secondary insulation layers. Primary bridging plates fill the spaces between adjacent primary insulation modules, and these bridging plates are pressed onto the flexible secondary shield above the secondary insulation layer. Existing technology, such as the invention patent publication CN117842286A, discloses a membrane-type cryogenic liquid cargo containment system in which bridging modules are installed on the flexible secondary shield; these bridging modules are also the primary bridging plates.

[0003] Before installation, the main layer bridging plate needs to be water-coated and then fixed by adhesive. Currently, the main method of applying adhesive to the main layer bridging plate is to manually position it and then apply it with adhesive application equipment. However, the adhesive application width varies for different main layer bridging plates, and the adhesive application equipment cannot meet the adhesive application requirements of different main layer bridging plates. Summary of the Invention

[0004] To address the issues of poor positioning and adaptability in existing adhesive coating equipment, this invention provides a main layer bridging plate adhesive coating device and method. This device enables automatic positioning during the main layer bridging plate adhesive coating process and can be adjusted to meet the adhesive coating requirements of different main layer bridging plates.

[0005] The technical objective of this invention is achieved through the following technical solution:

[0006] A main layer bridging plate adhesive coating device includes a coating platform, which includes a coating platform frame, a movable roller conveyor, an adhesive supply pipe fixing frame, an adhesive support frame, and an adhesive coating mechanism.

[0007] The moving roller conveyor is set above the coating platform frame to realize the transfer of the main layer bridging plate;

[0008] The adhesive application support frame includes a gantry bracket and a slide rail adjustment mechanism for adjusting the position of the adhesive application mechanism. The gantry bracket is installed on the coating platform frame, and the moving roller conveyor passes under the gantry bracket. The adhesive application mechanism is installed on the gantry bracket above the moving roller conveyor via the slide rail adjustment mechanism.

[0009] The glue supply tube fixing frame includes a first bearing seat, a support rod, and a fixing ring for supporting the glue supply tube. The vertically arranged support rod is rotatably connected to the coating platform frame through the first bearing seat, and the fixing ring is installed at the upper end of the support rod. The glue supply tube passes through the fixing ring and is connected to the glue coating mechanism.

[0010] The glue application mechanism includes a glue mixer and a glue application tube connected to the glue mixer. The glue supply tube includes a first glue supply tube and a second glue supply tube. The first glue supply tube and the second glue supply tube are connected to one end of the glue mixer. The other end of the glue mixer is connected to the middle of the glue application tube. The glue application tube and the glue mixer are arranged in a T-shape. A glue cavity is formed inside the glue application tube. A glue outlet is provided along the length of the glue application tube and is connected to the glue cavity.

[0011] A first positioning plate is also provided on one side of the moving roller conveyor for positioning the main layer bridging plate. The height of the first positioning plate is higher than that of the moving roller conveyor. When the main layer bridging plate moves along the moving roller conveyor, it moves against the first positioning plate.

[0012] Furthermore, the adhesive applicator includes a top cover plate, a tube body with an opening, an adhesive mixer connected to the top cover plate, and the opening of the top cover plate and the tube body are detachably connected.

[0013] Furthermore, a first driving block and a second driving block are respectively provided at both ends of the glue-applying tube inside the glue cavity. The first driving block and the second driving block are respectively connected to a driving unit that drives the first driving block and the second driving block to move along the length direction of the glue-applying tube inside the glue cavity. The first driving block and the second driving block are disposed in contact with the inner wall of the glue cavity, and the driving unit drives the first driving block and the second driving block to move to adjust the glue outlet size.

[0014] Furthermore, the dispensing port includes a first dispensing port, a second dispensing port, and a third dispensing port. The third dispensing port is located between the first dispensing port and the second dispensing port. The first driving block and the second driving block are used to adjust the lengths of the first dispensing port and the second dispensing port, respectively.

[0015] Furthermore, the width of the third dispensing port is greater than the width of the first dispensing port and the second dispensing port.

[0016] Furthermore, a conveying platform is also provided adjacent to the coating platform at one end of the moving roller conveyor. The conveying platform includes a conveying platform frame, a conveying roller conveyor, a second positioning plate, and a side push plate. The second positioning plate is located on one side of the conveying roller conveyor, and the side push plate is located on the other side of the conveying roller conveyor. The side push plate is connected to a linear drive device for driving the side push plate to move toward the second positioning plate. The second positioning plate and the side push plate are located at the starting end of the conveying roller conveyor, and the conveying end of the conveying roller conveyor is connected to the moving roller conveyor.

[0017] Furthermore, a third positioning plate is provided at the end of the conveying roller conveyor. The third positioning plate is flipped and set at the end of the conveying roller conveyor. When there is no main layer bridging plate on the moving roller conveyor, the third positioning plate flips to be lower than the upper surface of the conveying roller conveyor. When there is a main layer bridging plate on the moving roller conveyor, the third positioning plate flips to be higher than the upper surface of the conveying roller conveyor.

[0018] Furthermore, a cleaning device for removing dust from the surface of the main layer bridging plate is installed above the middle area of ​​the conveyor roller conveyor.

[0019] Furthermore, the coating platform frame of the coating platform is provided with a first positioning block on its side, and the conveying platform frame of the conveying platform is provided with a second positioning block on its side corresponding to the first positioning block. The first positioning block is provided with a protruding plug, and the second positioning block is provided with a slot that matches the plug. The plug is provided with a socket, and the bottom of the slot is provided with a socket. The plug is inserted into the slot, and the socket of the plug is aligned vertically with the socket at the bottom of the slot. A pin is inserted into the vertically aligned socket to connect the plug and the slot.

[0020] The present invention also provides a method for applying adhesive to a main layer bridging plate, the method comprising applying adhesive using the aforementioned adhesive application apparatus, and the method comprising:

[0021] Step 1: Adjust the lateral position of the glue application mechanism according to the width of the main layer bridging board to be glued, so that the center of the glue application mechanism is aligned with the center of the width of the main layer bridging board.

[0022] Step 2: When the main layer bridging plate to be coated with adhesive moves along the moving roller track and approaches below the adhesive coating mechanism, the height of the adhesive coating mechanism is adjusted according to the thickness of the main layer bridging plate so that the adhesive coating mechanism is close to the upper surface of the main layer bridging plate.

[0023] Step 3: When the main layer bridging plate moves to the bottom of the glue application mechanism, the glue application mechanism releases glue onto the upper surface of the main layer bridging plate. During the glue release process, the main layer bridging plate moves at a constant speed under the action of the moving roller conveyor. The glue application mechanism forms three glue channels on the upper surface of the main layer bridging plate. The thickness of the middle glue channel is greater than the thickness of the glue channels on both sides. The glue channels extend from one end of the main layer bridging plate to the other end along the length direction of the main layer bridging plate. The glue channels on both sides leave a margin gap from the width edge of the main layer bridging plate.

[0024] Step 4: After the main layer bridging plate has completely passed under the glue application mechanism, the glue application mechanism stops dispensing glue and moves upward to reset via the slide rail adjustment mechanism. When the next main layer bridging plate moves under the glue application mechanism, step 3 is executed.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. The main layer bridging plate adhesive coating device of the present invention realizes the movement and positioning of the main layer bridging plate through the cooperation of the moving roller and the first positioning plate. When the main layer bridging plate moves to the bottom of the coating mechanism, the automatic coating operation is performed, which facilitates batch coating operation and uniform coating standards.

[0027] 2. The adhesive coating mechanism in this invention can mix the two components of a two-component adhesive through an adhesive mixer. The mixed adhesive directly enters the coating tube to await coating. The adhesive components do not come into contact before entering the coating tube. The two-component adhesive can be mixed according to the actual usage, reducing the waste of adhesive.

[0028] 3. The glue application mechanism in this invention, through the cooperation of the first driving block, the second driving block and the driving unit, can adjust the size of the glue outlet according to the width of the main layer bridging board, which can meet the glue application needs of main layer bridging boards of different specifications.

[0029] 4. In the main layer bridging plate adhesive coating device of the present invention, the coating platform and the conveying platform can be used in combination or the coating platform can be used alone, which is highly flexible. The continuous coating operation of the main layer bridging plate can be realized by the cooperation of the conveying platform and the coating platform, which is suitable for large-scale coating operations.

[0030] 5. The present invention also provides a method for applying adhesive to a main layer bridging board. The method involves forming three adhesive channels on the surface of the main layer bridging board using an adhesive application mechanism. The thickness of the middle adhesive channel is greater than that of the two side adhesive channels. When the main layer bridging board is installed between the main layer insulation modules, the adhesive in the middle adhesive channel diffuses outward to ensure that the adhesive on the mounting surface of the main layer bridging board is fully covered. At the same time, it avoids the situation where too much adhesive cannot overflow, which would result in the main layer bridging board not being able to guarantee the flatness with the upper surface of the main layer insulation module after installation.

[0050] The technical solution of the present invention will be further described below with reference to specific embodiments:

[0051] A primary bridging plate adhesive coating apparatus includes a coating platform, such as... Figure 1 As shown, the coating platform includes a coating platform frame 1, a moving roller conveyor 2, a glue supply tube fixing frame 3, a glue application support frame 4, and a glue application mechanism 5.

[0052] The moving roller conveyor 2 is set above the coating platform frame 1 to realize the transfer of the main layer bridging plate 9;

[0053] The glue application support frame 4 includes a portal frame 6 and a slide rail type adjustment mechanism 7 for adjusting the position of the glue application mechanism. The portal frame 6 is installed on the coating platform frame 1, and the moving roller conveyor 2 passes through the bottom of the portal frame 6. The glue application mechanism 5 is installed on the portal frame 6 above the moving roller conveyor 2 via the slide rail type adjustment mechanism 7.

[0054] Specifically, the adhesive-coated support frame, such as Figure 3 As shown, the portal frame 6 includes a vertical support 601 and a horizontal support 602. The vertical support 601 is supported below both ends of the horizontal support 602 to form the portal frame 6.

[0055] The slide rail type adjustment mechanism 7 is used to adjust the position of the glue application mechanism, including the height position and horizontal lateral position of the glue application mechanism. Specifically, the slide rail type adjustment mechanism 7 includes a horizontal track mounting plate 701, a horizontal track 702 mounted on the horizontal track mounting plate 701, a vertical track mounting plate 703 that cooperates with the horizontal track 702, a vertical track 704 mounted on the vertical track mounting plate 703, and a glue application mechanism mounting plate 705 that cooperates with the vertical track 704, on which the glue application mechanism 5 is mounted.

[0056] The horizontal track mounting plate 701 is installed on the side of the portal frame 6, and the vertical track mounting plate 703 is provided with a slider that slides with the horizontal track 702. In this embodiment, a horizontal track 702 is provided at the upper and lower positions near the horizontal track mounting plate 701, and a drive screw 706 is provided between the two horizontal tracks 702. The drive is such as a motor. The two ends of the screw 706 are supported and fixed on the horizontal track mounting plate 701 by bearings. A screw nut that is threaded with the screw 706 is provided on the back of the vertical track mounting plate 703. The screw nut is displaced by the rotation of the screw 706, thereby realizing the horizontal movement of the vertical track mounting plate 703 along the horizontal track 702.

[0057] A vertical track 704 is installed near the left and right sides of the vertical track mounting plate. A lead screw 707 with a drive is also installed between the two vertical tracks 704. Referring to the setting of the lead screw 706, a corresponding slider is set on the glue application mechanism mounting plate to cooperate with the vertical track. A lead screw nut is set on the lead screw between the vertical tracks 704. The rotation of the lead screw 707 drives the glue application mechanism mounting plate 705 to move up and down along the vertical track 704.

[0058] A clamping part for fixing the glue application mechanism 5 is provided on the glue application mechanism mounting plate 705, and the glue application mechanism mounting plate 705 is fixed by the clamping part. More specifically, in one embodiment, the clamping part is such as a clamping block 708 with a clamping groove, the clamping groove clamps the outside of the glue mixer 501, and the clamping block is fixed to the glue application mechanism mounting plate 705 by screws.

[0059] To increase the stability of the portal frame 6, diagonal bracing brackets 603 are also provided on both sides of the vertical bracket 601.

[0060] The glue supply tube fixing frame 3 includes a first bearing seat 301, a support rod 302, and a fixing ring 303 for supporting the glue supply tube. The support rod 302 is vertically arranged and is mounted on the side of the coating platform frame 1 via the first bearing seat 301. The fixing ring 303 is installed at the upper end of the support rod 302. In use, the glue supply tube passes through the fixing ring and connects to the glue coating mechanism 5. The fixing ring 303 supports the glue supply tube to avoid affecting the operation on the coating platform. When the position of the glue coating mechanism 5 is adjusted, the support rod 302 is rotated relative to the first bearing seat 301 to adjust the direction of the glue supply tube. In this embodiment, the lower end of the support rod 302 is supported by the first bearing seat 301, and a crossbeam 304 perpendicular to the support rod 302 is provided at the upper end of the support rod 302. The fixing ring 303 is fixed below the crossbeam 304.

[0061] like Figure 2 As shown, the glue application mechanism 5 includes a glue mixer 501 and a glue application tube 502 connected to the glue mixer 501. The glue supply tube includes a first glue supply tube and a second glue supply tube. The first glue supply tube and the second glue supply tube are connected to one end of the glue mixer 501. The other end of the glue mixer 501 is connected to the middle of the glue application tube 502. The glue application tube 502 and the glue mixer 501 are arranged in a T-shape. A glue cavity is formed inside the glue application tube 502. A glue outlet is provided along the length of the glue application tube 502 and is connected to the glue cavity. The glue components in the first glue supply tube and the glue components in the second glue supply tube are mixed in the glue mixer 501. With the conveying of raw materials in the first glue supply tube and the second glue supply tube, the mixed glue moves into the glue cavity and is then applied to the main layer bridge plate from the glue cavity through the glue outlet.

[0062] A first positioning plate 8 for positioning the main layer bridging plate is also provided on one side of the moving roller conveyor 2. The height of the first positioning plate 8 is higher than that of the moving roller conveyor 2. When the main layer bridging plate 9 moves along the moving roller conveyor 2, it moves against the first positioning plate 8.

[0063] Specifically, the moving roller conveyor 2 includes several rollers, a motor, and a transmission mechanism. The rollers are arranged in parallel on the coating platform frame 1. The motor drives the rollers to rotate synchronously through the transmission mechanism. The transmission mechanism can be a gear drive, a chain drive, or a sprocket drive. In this embodiment, a transmission wheel is provided at the end of the roller. The motor drives the transmission wheel to rotate through a chain or a transmission belt.

[0064] As a preferred option, such as Figure 4 and Figure 5 As shown, the glue applicator 502 includes an upper cover plate 503 and a tube body 504 with an opening. A glue mixer 501 is connected to the upper cover plate 503. The opening 505 of the upper cover plate 503 and the tube body 504 are detachably connected, and the glue outlet is located on the tube body 504. In this embodiment, the glue mixer 501 is a hollow tube. The glue mixer 501 connects to one side of the upper cover plate corresponding to the opening 505 of the tube body. The upper cover plate 503 is connected to the opening 505 by screws or the like to form a relatively closed glue cavity. The detachable connection between the upper cover plate 503 and the tube body 504 facilitates opening the glue cavity for cleaning and maintenance.

[0065] Preferably, to facilitate adjustment of the glue outlet size, a first driving block 506 and a second driving block 507 are respectively provided at both ends of the glue cavity near the glue application tube 502. The first driving block 506 and the second driving block 507 are respectively connected to a driving unit 508 that drives the first driving block 506 and the second driving block 507 to move along the length of the glue application tube 502 within the glue cavity. The driving unit 508 is like a cylinder. The first driving block 506 and the second driving block 507 are disposed against the inner wall of the glue cavity. In this embodiment, the glue cavity is a cylindrical cavity, and the first driving block and the second driving block are also cylindrical structures adapted to the size of the glue cavity. The first driving block 506 and the second driving block 507 are moved by the driving unit 508 to cover part of the glue outlet, so that the size of the glue outlet can be adjusted.

[0066] The glue outlet can be a single outlet along the length of the glue applicator 502, or it can be segmented. This embodiment provides a three-segment glue outlet, such as... Figure 5 As shown, the dispensing port includes a first dispensing port 509, a second dispensing port 510, and a third dispensing port 511. The third dispensing port 511 is located between the first dispensing port 509 and the second dispensing port 510. The first driving block 506 and the second driving block 507 are used to adjust the lengths of the first dispensing port 509 and the second dispensing port 510, respectively.

[0067] Preferably, the width of the third adhesive outlet 511 is greater than the width of the first adhesive outlet 509 and the second adhesive outlet 510. When adhesive is dispensed simultaneously, the amount of adhesive dispensed at the third adhesive outlet 511 is greater than the amount of adhesive dispensed at the first adhesive outlet 509 and the second adhesive outlet 510. This results in three adhesive channels being formed on the surface of the main layer bridging board. The adhesive thickness of the middle adhesive channel is greater than the adhesive thickness of the two side adhesive channels. When the main layer bridging board is subsequently installed between the main layer insulation modules, the adhesive channels are squeezed, and the adhesive in the middle adhesive channel overflows to both sides, filling the space between the adhesive channels with adhesive and ensuring the bonding quality of the main layer bridging board installation.

[0068] In one embodiment, the three dispensing ports are all the same length of 85mm, that is, the maximum width of the adhesive channel formed by the coating of the first dispensing port 509 and the second dispensing port 510 is 85mm, and the distance between adjacent dispensing ports is 10mm.

[0069] Preferably, a waste collection box 10 is also provided below the moving roller conveyor. The waste collection box is located below the glue application mechanism 5. After the glue is applied to each main layer bridging board, excess glue may flow out from the glue outlet of the glue application mechanism, and the flowing glue falls into the waste collection box 10. When setting up the glue application mechanism, it is preferable to align the glue outlet of the glue application mechanism between two adjacent rollers to avoid glue dripping onto the rollers.

[0070] As a preferred option, such as Figure 6 and Figure 8 As shown, a conveying platform is also provided adjacent to the coating platform at one end of the moving roller conveyor 2. The conveying platform includes a conveying platform frame 11, a conveying roller conveyor 12, a second positioning plate 13, and a side push plate 14. The second positioning plate 13 is located on one side of the conveying roller conveyor 12, and the side push plate 14 is located on the other side of the conveying roller conveyor 12. The side push plate 14 is connected to a linear drive device for driving the side push plate 14 to move towards the second positioning plate 13. The linear drive device is such as a cylinder or an electric cylinder. The second positioning plate 13 and the side push plate 14 are located at the starting end of the conveying of the conveying roller conveyor 12, and the conveying end of the conveying roller conveyor is connected to the moving roller conveyor 2. The conveying roller conveyor 12 also includes several rollers, and their arrangement can refer to the arrangement of the moving roller conveyor.

[0071] Preferably, to avoid having multiple main layer bridging plates on the coating platform, such as Figure 7 As shown, a third positioning plate 15 is also provided at the end of the conveying roller 12. The third positioning plate 15 is flipped and set at the end of the conveying roller 12. When there is no main layer bridging plate on the moving roller 2, the third positioning plate 15 flips to be lower than the upper surface of the conveying roller 12. When there is a main layer bridging plate on the moving roller 2, the third positioning plate 15 flips to be higher than the upper surface of the conveying roller 12.

[0072] This embodiment provides a method for flipping a third positioning plate. The third positioning plate is connected to a robotic arm, which is fixed on a bracket for mounting the conveyor rollers. The robotic arm achieves the flipping via a motor, hydraulic rod, cylinder, servo motor, etc. To automate the flipping, sensors can be installed on the moving rollers to assist in the operation, such as infrared sensors and pressure sensors. When a main layer bridging plate is detected on the moving rollers, the PLC controls the robotic arm to flip the third positioning plate to a position higher than the upper surface of the conveyor roller 12, preventing the main layer bridging plate on the conveyor roller 12 from transferring to the moving roller 2. When no main layer bridging plate is detected on the moving rollers, the third positioning plate flips to a position lower than the upper surface of the conveyor roller 12, allowing the main layer bridging plate on the conveyor roller 12 to transfer to the moving roller 2 for the next coating operation.

[0073] Preferably, a cleaning device 16 for removing dust from the surface of the main layer bridging plate is also provided above the middle area of ​​the conveyor roller 12. In this embodiment, the cleaning device includes a cleaning device support frame 1601 and a dust removal host 1602 mounted on the support frame 1601. The dust removal host is equipped with an exhaust fan system and a suction head connected to the exhaust fan system. A detection device, such as a pressure sensor or infrared sensor, is also provided at the starting end of the cleaning device support frame 1601 near the conveyor roller 12 to detect the main layer bridging plate. When a main layer bridging plate is detected on the conveyor roller 12 and reaches the detection range of the detection device, the exhaust fan system starts operating and uses the suction head to clean the upper surface of the main layer bridging plate.

[0074] As a preferred option, such as Figure 8 and Figure 9 As shown, to facilitate the combined use of the conveying platform and the coating platform, the coating platform frame 1 of the coating platform is provided with a first positioning block 17 on its side, and the conveying platform frame 11 of the conveying platform is provided with a second positioning block 18 on its side corresponding to the first positioning block 17. The first positioning block 17 is provided with a protruding plug 1701, and the second positioning block 18 is provided with a slot 1801 that is adapted to the plug 1701. The plug 1701 is provided with a socket 1702, and the bottom of the slot 1801 is provided with a socket corresponding to the socket of the plug 1701. After the plug 1701 is inserted into the slot 1801, the socket of the plug 1701 and the socket at the bottom of the slot 1801 are aligned vertically. A pin 19 is inserted into the vertically aligned socket to connect the plug 1701 and the slot 1801.

[0075] The conveying platform can also be equipped with a second positioning block 18 at one end and a first positioning block 17 at the other end, so that the length of the conveying platform can be extended through the cooperation of the first positioning block 17 and the second positioning block 18.

[0076] Preferably, a barcode reader 20 can be installed near the input end of the moving roller conveyor. Correspondingly, barcodes, QR codes, etc. containing coating information are affixed to the main layer bridging plate. When the main layer bridging plate reaches the barcode reader 20 at a fixed position, the barcode reader reads the barcodes and QR codes on the main layer bridging plate to obtain coating information. The coating information includes the size information of the main layer bridging plate, coating width, etc. The PLC control system of the coating mechanism adjusts the position of the coating mechanism, the size of the glue outlet, coating time, etc. according to the obtained coating information.

[0077] A barcode reader 21 can also be installed near the end of the conveyor rollers, specifically at the rear end of the cleaning device 16. When the conveyor platform is used in conjunction with the coating platform, the main layer bridging plate reaches the barcode reader 21 after passing through the cleaning device 16, acquiring coating information. This information is then used by the PLC control system of the coating mechanism to adjust the position of the coating mechanism, the size of the glue outlet, and the coating time. When both barcode readers 20 and 21 are present, only one needs to be used. Barcode readers 20 and 21 can be handheld barcode scanners or fixed barcode scanners.

[0078] The coating platform can also be equipped with a control box 22, which is equipped with a control switch. By operating the control box, semi-automatic glue coating of the main layer bridging board can be achieved, including manually adjusting the position of the coating mechanism, the size of the glue outlet, and the start and end times of coating.

[0079] This embodiment also provides a method for applying adhesive to a main layer bridging plate. The method utilizes the aforementioned adhesive application apparatus and includes:

[0080] Step 1: The PLC control system of the coating mechanism obtains the coating information of the main layer bridging board to be coated, including the length, width, thickness and coating parameters of the main layer bridging board. According to the width of the main layer bridging board to be coated, the lateral position of the coating mechanism is adjusted by the slide rail adjustment mechanism so that the center of the coating mechanism is aligned with the center of the width of the main layer bridging board.

[0081] During alignment, the width side of the main layer bridging plate is kept in contact with the first positioning plate. With the first positioning plate as the reference, the width of the main layer bridging plate is W, and the distance from the center of the width of the main layer bridging plate to the first positioning plate is W / 2. The coating mechanism moves under the action of the slide rail type adjustment mechanism 7, so that the distance of the center of the coating mechanism relative to the distance of the first positioning plate is equal to W / 2.

[0082] Step 2: When the main layer bridging plate to be coated with adhesive moves along the moving roller track and approaches below the adhesive coating mechanism, the height of the adhesive coating mechanism is adjusted according to the thickness of the main layer bridging plate so that the adhesive coating mechanism is close to the upper surface of the main layer bridging plate.

[0083] When adjusting the height, the thickness D of the main layer bridging plate of different specifications is different, but the height of the moving roller where the main layer bridging plate is located is consistent. The height position of the coating mechanism is adjusted by the slide rail type adjustment mechanism 7 with the height of the upper surface of the moving roller as the reference.

[0084] Step 3: When the main layer bridging plate moves to the bottom of the glue application mechanism, the glue application mechanism releases glue onto the upper surface of the main layer bridging plate. The glue is a two-component polyurethane glue, and the two components are mixed in the glue mixer 501.

[0085] During the glue release process, the main layer bridging plate moves at a uniform speed under the action of the moving roller conveyor, and the glue coating mechanism forms three glue channels 23 on the upper surface of the main layer bridging plate, such as... Figure 10 As shown, the thickness of the middle adhesive channel 23 is greater than the thickness of the two side adhesive channels 23. The adhesive channel 23 extends from one end of the main layer bridging plate to the other end along the length direction of the main layer bridging plate 9. The adhesive channels 23 on both sides have a margin gap from the width edge of the main layer bridging plate.

[0086] Step 4: After the main layer bridging plate has completely passed under the glue application mechanism, the glue application mechanism stops dispensing glue and moves upward to reset via the slide rail adjustment mechanism. When the next main layer bridging plate moves under the glue application mechanism, step 3 is executed.

[0087] After the main layer bridging plate has been coated, it proceeds to the next step of installation. During installation, if... Figure 11 As shown, the main insulation module 25 is prefabricated on the secondary insulation module 24. A rigid secondary shield 26 is laid between the main insulation module 25 and the secondary insulation module 24, and a flexible secondary shield 27 is laid between adjacent secondary insulation modules 24. The flexible secondary shield 27 and the rigid secondary shield 26 form a complete secondary shield. A notch is formed between adjacent main insulation modules 25 for the installation of the main layer bridging plate 9. The adhesive-coated side of the main layer bridging plate 9, which is coated with three adhesive strips, faces the flexible secondary shield 27. The main layer bridging plate 9 is embedded between the main insulation modules. The main layer bridging plate is squeezed so that the upper surface of the main layer bridging plate is flush with the upper surface of the main insulation module. The main layer bridging plate is temporarily fixed, such as by adding pressure blocks to maintain pressure on the main layer bridging plate until the adhesive is cured.

[0088] This embodiment is merely a further explanation of the present invention and is not intended to limit the present invention. Those skilled in the art can make non-inventive modifications to this embodiment as needed after reading this specification, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
