Description

Technical Field

[0001] This utility model belongs to the field of color steel sandwich panel production and processing technology, specifically, it relates to a color steel sandwich panel production line. Background Technology

[0002] Color-coated steel sandwich panels are a new type of building envelope material that integrates load-bearing, thermal insulation, waterproofing, and decoration. They can be widely used in various construction applications, including roofs and walls of industrial plants, public buildings, warehouses, special buildings, and large-span steel structure houses, as well as interior and exterior wall decorations. Color-coated steel sandwich panels use color-coated steel sheets as the face material and self-extinguishing polystyrene, polyurethane, glass wool, rock wool, etc., as the core material. During production, the core material and the top and bottom face materials are fixed together with adhesive, and then composited and trimmed in sequence to form the color-coated steel sandwich panel.

[0003] Color steel sandwich panels typically include two types. One type consists of a color steel wall panel bottom material 13 (color steel bottom plate), a core material 12, and a color steel top plate 11 arranged sequentially from bottom to top (e.g., Figure 1 and Figure 2 (As shown); another type consists of a color steel roofing sheet with the following components arranged sequentially from bottom to top: lower color steel sheet 14 (lower color steel sheet), core material 12, and upper color steel sheet 11 (as shown). Figure 3 As shown), the lower material 14 of the color steel roofing sheet is provided with several guide strips 15. It should be noted that "lower color steel sheet" in this paragraph refers to the sheet material initially located at the bottom in the production process; however, in actual applications (such as as roofing or wall panels), this sheet material is located at the top / outer side after installation. To ensure consistency with the production line operation logic below, this document will consistently use the naming from this process perspective.

[0004] Existing color steel sandwich panel production lines include uncoiling stations, forming stations, core material conveying stations, adhesive dispensing stations, and verification and trimming stations. Because the specifications of color steel wall panels and color steel roofing sheets are different, the forming equipment at the forming stations cannot be shared. To address this issue, existing manufacturers typically use two methods: First, setting up multiple independent production lines, each dedicated to producing color steel wall panels or color steel roofing sheets. This approach results in high equipment investment costs, a large footprint, and the dedicated production line is easily idle when there are insufficient orders for a particular product, leading to resource waste. Second, setting up multiple forming machines of different models side-by-side at the forming station (e.g., one roofing sheet forming machine and multiple wall panel forming machines). While this approach reduces the footprint, switching products requires the use of gantry cranes or other lifting equipment to transport the target forming machine to the work center position on the production line. The current operation is cumbersome, time-consuming, and labor-intensive, and has the following inherent drawbacks: 1. Poor positioning accuracy: Overhead crane transport cannot achieve precise positioning, and after the forming machine is in place, a large amount of tedious manual adjustment is often required to ensure alignment with the production line center, resulting in extremely low debugging efficiency; 2. Low automation: The entire changeover process heavily relies on the operator's experience, making automated control impossible, which contradicts the concept of modern intelligent manufacturing; 3. Safety hazards: Frequent hoisting and movement of heavy equipment poses a high safety risk. Therefore, it is necessary to provide an integrated solution that enables rapid, accurate, and automatic switching and positioning of multiple forming machines. Utility Model Content

At the same time, the use of this structure makes the process efficient, realizes the seamless connection of multiple processes, reduces intermediate transfers, and improves production efficiency and automation level.

[0046] According to this utility model, the adhesive application device is a reciprocating sprayer, which is located on one side of the color steel upper plate forming machine.

[0047] The reciprocating spraying machine includes a first support body, on which are provided the A glue pipe, the B glue pipe, the first air pipe and the composite nozzle. The composite nozzle is provided with an A glue inlet, a B glue inlet, an air inlet and a mixing chamber.

[0049] Furthermore, the first and second solenoid valves are designed so that when the production line encounters a fault, the first and second solenoid valves close and stop the liquid supply, which can prevent the glue from continuing to be supplied to the adhesive and avoid problems such as glue backflow or air mixing into the pipeline.

[0050] According to this utility model, the reciprocating spraying machine further includes a first detection element, a second detection element, and a fifth trigger block. The first and second detection elements are disposed on the first support body. The fifth trigger block moves synchronously with the composite nozzle. In use, the first and second detection elements are triggered sequentially by the fifth trigger block, thereby accurately controlling the spray origin and spray end point of the nozzle, and thus controlling the spraying range of the composite nozzle.

[0051] Furthermore, in this embodiment, the fifth trigger block is disposed on the connector, and the first detection element and the second detection element are disposed on the linear slide rail.

[0052] Furthermore, both the first and second detection elements are photoelectric sensors, and the fifth trigger block is a baffle.

[0053] Furthermore, the first support body is provided with a telescopic arm and a first drive mechanism for controlling the linear movement of the telescopic arm, and the front end of the telescopic arm is provided with the composite nozzle.

[0054] Furthermore, the first drive mechanism includes a linear slide rail, a timing belt, a connector, and a motor that drives the timing belt to rotate. The connector is fixed on the timing belt, and a slider is provided below the connector, which can slide relative to the linear slide rail. The connector is fixed above the telescopic arm.

[0055] According to this utility model, the composite nozzle includes a connector and a nozzle body. The nozzle body is provided with the mixing chamber, and the connector is provided with the A glue inlet, the B glue inlet, and the air inlet. The connector and the nozzle body are detachably connected.

[0056] Furthermore, the connector and the nozzle body are connected by a threaded connection; or,

[0057] The connector and the nozzle body are snap-fitted together; or...

[0058] The connector and nozzle body are connected by fasteners (nuts and bolts).

[0059] According to this utility model, the mixing structure is a spiral mixing structure, which consists of spiral blades. The spiral blades and the mixing chamber form a spiral mixing chamber, which mixes adhesive A and adhesive B under the drive of compressed air. When adhesive A, adhesive B and gas flow through the spiral blades 5255, they are repeatedly divided, sheared and recombined, thereby achieving thorough mixing; or, the mixing structure is a spiral pipe.

[0060] According to this utility model, the first support body is provided with a toolbox for storage.

[0061] According to this utility model, when the adhesive application device is used to drip or apply adhesive A and adhesive B onto the upper and lower plates or core material of the color steel sandwich panel, the color steel sandwich panel production line further includes an adhesive leveling device. The adhesive leveling device includes a second support body, on which is provided a mounting frame for mounting an adhesive leveling strip, a second driving mechanism for driving the mounting frame to move horizontally, and an adhesive leveling strip disposed on the mounting frame. The second driving mechanism is used to drive the adhesive leveling strip to reciprocate linearly along the width direction of the color steel plate. The adhesive leveling strip is a silicone strip made of silicone material. The coating surface of the adhesive leveling strip is a plane, which is beneficial for applying adhesive A and adhesive B. The adhesive leveling strip 534 can be obtained commercially.

[0062] The color steel sandwich panel production line is equipped with two sets of glue-applying devices, which are respectively located at the front and rear middle sections of the conveying direction of the upper plate forming and glue-applying stations, and are used for applying glue to the upper and lower materials of the color steel panels.

[0063] According to this utility model, the second driving mechanism includes a drive motor and a crank-connecting rod mechanism; the output shaft of the drive motor is connected to the crank of the crank-connecting rod mechanism, and the connecting rod of the crank-connecting rod mechanism is hinged to the mounting frame to convert the rotational motion of the drive motor into the reciprocating linear motion of the mounting frame; or,

[0064] The drive mechanism includes a drive motor, an eccentric wheel, a rocker arm, and a connecting rod. One end of the rocker arm is hinged to the bracket body, and the other end is hinged to the eccentric wheel. One end of the connecting rod is hinged to the eccentric wheel, and the other end is hinged to the mounting frame. The rotational motion of the eccentric wheel is converted into the reciprocating linear motion of the mounting frame, and then into the direct reciprocating motion of the adhesive strip.

[0065] According to this utility model, the mounting bracket includes a first mounting plate and a second mounting plate. The first and second mounting plates are respectively provided with oblong holes. The applicator strip is provided with corresponding oblong holes. In use, a fixing component (e.g., a wing nut) passes sequentially through the second mounting plate, the applicator strip, and the first mounting plate, thereby fixing the applicator strip to the mounting bracket. The oblong holes allow adjustment of the position of the applicator strip, ensuring that both adhesive A and adhesive B can be applied.

[0066] Furthermore, the second bracket body is also equipped with a third lifting device for controlling the up and down movement of the mounting frame. When it is necessary to wipe the adhesive strip, simply raise the mounting frame to move the adhesive strip away from the steel plate to be coated, and then the operator can wipe the adhesive strip without having to remove it. This is convenient to use, and the overall wiping time is very short, which can avoid the problem of the entire color steel plate being scrapped due to the interruption of adhesive application.

[0067] To further optimize the problem caused by the lifting mechanism used to drive the lifting strip in traditional spin coaters needing to move horizontally along with the spin coater, this embodiment adopts a split design for the mounting frame.

[0068] The mounting bracket includes an active bracket and a transmission bracket. The active bracket is provided with the first mounting plate and the second mounting plate. The active bracket is connected to the second drive mechanism, which drives the glue-spreading strip to perform a horizontal reciprocating glue-spreading motion. The transmission bracket is connected to a third lifting device. A rotating structure is provided between the active bracket and the transmission bracket, allowing the active bracket to move horizontally relative to the transmission bracket, thereby separating the horizontal glue-spreading motion from the vertical lifting motion.

[0069] Furthermore, the rotating structure includes a first rotating member mounted on the active support with a first shaft and sleeved on the first shaft, and a second rotating member mounted on the transmission support with a second shaft and sleeved on the second shaft. The first and second rotating members are connected together, thereby separating the lifting motion of the third lifting device from the horizontal motion of the uniform adhesive strip driven by the drive mechanism. In use, the third lifting device controls the transmission support to move up and down, thereby causing the active support to move up and down accordingly.

[0070] Furthermore, the third lifting device includes a cylinder and a second air pipe, and the piston rod of the cylinder is connected to the transmission bracket.

[0071] The uniform adhesive strip is provided with a cutting slit to facilitate the uniform passage of adhesive A and adhesive B.

[0072] The beneficial effect of this utility model's color steel sandwich panel production line is that it enables rapid and precise switching between the production of different specifications of color steel wall panels and roofing sheets on a single production line, greatly enhancing production flexibility and market responsiveness. Specifically, this is reflected in:

[0073] 1. This embodiment arranges various specifications of color steel wall panel underlay forming machines in a row, and sets them side by side with color steel roofing sheet underlay forming machines. During use, by combining the drive device and positioning components, the color steel roofing sheet underlay forming machine or the color steel wall panel underlay forming machine can move relative to the slide rail, and stops moving when it reaches the target position, achieving precise positioning. Compared with the traditional method, this not only eliminates the hassle of traditional overhead crane handling but also solves the problem of precise positioning, greatly reducing production costs. During use, the operator only needs to select the forming machine to be used via a button, and the system will automatically move it and precisely position it to the target location, while simultaneously moving the forming machine at the target location to the waiting area, achieving the "no need for repositioning" problem. This greatly improves production efficiency and equipment utilization, reduces operational difficulty and reliance on operator experience.

[0074] 2. The setting of the lower plate forming station, through equipment integration and sharing, significantly reduces the total investment in equipment and the factory floor area, while avoiding the idleness of dedicated production lines due to insufficient orders, and greatly improving equipment utilization.

[0075] 3. The color steel sandwich panel production line of this utility model is particularly suitable for multi-variety, small-batch production mode, which can effectively help enterprises adapt to diversified market demands while controlling costs.

[0076] In addition, the color steel sandwich panel production line of this utility model also has other beneficial effects:

[0077] 1. The upper plate pressing and adhesive application station of this utility model integrates upper plate pressing, multi-material conveying (conveying the upper color steel plate, core material, and lower color steel plate) and adhesive application functions into a single station, which has significant effects: First, the structure is compact, adopting a three-dimensional layered layout, which greatly reduces the footprint of the equipment; second, the process is efficient, concentrating multiple processes such as upper plate pressing, core material introduction, and upper and lower plate adhesive application, which originally needed to be carried out in multiple independent stations, into one place, realizing seamless connection of multiple processes, simplifying the material flow path, and improving production efficiency and automation level; third, the quality is controllable, shortening the process from adhesive application to lamination, and ensuring the bonding reliability of the color steel sandwich panel.

[0078] 2. The adhesive application device is a reciprocating sprayer. Through the coordinated arrangement of a first solenoid valve, a second solenoid valve, a third solenoid valve, and a throttle valve, during production, the compressed air entering the mixing chamber collides and mixes with the adhesive within the mixing chamber. Simultaneously, the mixed adhesive is broken down into fine mist particles, ultimately providing the propulsion for forward spraying. When production stops, compressed air enters the composite nozzle directly through the third solenoid valve at high speed and large flow rate. This is used to quickly spray any remaining two-component adhesive from inside the composite nozzle onto the upper or lower material of the color steel sheet, preventing the two-component adhesive from solidifying in the mixing chamber after flow ceases, thus ensuring that the composite nozzle is not clogged upon the next startup.

[0079] 3. The setting of the coating strip in the coating device makes cleaning particularly convenient. When the coating strip is covered with two-component adhesive, the residue can be removed by simply wiping it, reducing the material and labor costs caused by frequent replacement of disposable foam strips or sound insulation cotton.

[0080] 4. The first and second baffles of the second sheet conveyor at the core material conveying station allow for staggered joints between adjacent core sheets as multiple sets of core sheets sequentially enter the upper plate forming and adhesive application stations. This effectively improves the flexural strength of the final formed color steel sandwich panel. The coordinated arrangement of the suction cup device, material detection device, first plate feeding machine, and second plate feeding machine at the core material conveying station enables automated continuous feeding of core sheets, effectively solving the problem of sheet handling control caused by inconsistent raw material stack heights, and improving production stability and efficiency.

Additionally, features described with reference to certain examples may be combined in other examples.

[0110] In the following embodiments, the color steel lower plate is the lower material of color steel wall panel or color steel tile panel.

[0111] Example 1

[0112] like Figure 4 As shown, a color steel sandwich panel production line includes a lower plate uncoiling station 2, a lower plate forming station 3, an upper plate uncoiling station 4, and an upper plate forming and adhesive application station 5 arranged sequentially along the production line.

[0113] like Figure 1-3 As shown, the lower plate uncoiling station 2 is used for uncoiling the lower material 13 of the color steel wall panel or the lower material 14 of the color steel roofing sheet. It should be noted that the specifications of the lower material 13 of the color steel wall panel and the lower material 14 of the color steel roofing sheet are usually varied. Therefore, after determining the specifications, different specifications of color steel coils can be replaced at the lower plate uncoiling station 2. The structure of the lower plate uncoiling station 2, which can be applied to color steel coils of different specifications, is existing technology and will not be elaborated upon here.

[0114] like Figure 1-4 As shown, the upper plate uncoiling station 4 is used for uncoiling the color steel upper plate 11; it should be noted that the specifications of the color steel wall panel surface material and the color steel roofing sheet surface material are usually the same, therefore, this utility model embodiment uniformly uses the name "color steel upper plate". If the color steel upper plate also includes multiple specifications, the lower plate uncoiling station can be used to set up color steel coils suitable for multiple specifications.

[0115] The upper plate forming and adhesive application station 5 includes a color steel upper plate forming machine 51 for forming a color steel upper plate 11 from a flat steel strip and an adhesive application device, which is used to apply adhesive to the upper surface of the color steel upper plate and the lower surface of the color steel lower plate / upper surface of the core material.

[0116] like Figures 4-7 As shown, the lower plate forming station 3 includes several color steel tile lower plate forming machines 31 for forming flat steel strips into color steel tile lower plates and several color steel wall panel lower plate forming machines 32 for forming flat steel strips into color steel wall panel lower plates. A guide rail 33 is installed on the floor of the station. A first driving device is used to drive the color steel tile lower plate forming machines 31 to slide along the guide rail 33, and a second driving device is used to drive the color steel wall panel lower plate forming machines 32 to slide along the guide rail 33. A positioning component is used to limit the movement of the color steel tile lower plate forming machine 31 or the color steel wall panel lower plate forming machine 32 to a target position. The positioning component includes a sensor and a trigger block for triggering the sensor to emit a signal. The sensor is electrically connected to the first driving device and / or the second driving device. It should be noted that the target position here refers to the position where the color steel tile lower plate forming machine 31 or the color steel wall panel lower plate forming machine 32 needs to be positioned for connection with the lower plate unwinding station. In use, the first drive device moves the corrugated steel sheet undercoat forming machine, or the second drive device moves the corrugated steel wall panel undercoat forming machine. When the trigger block on the corrugated steel sheet undercoat forming machine or the corrugated steel wall panel undercoat forming machine reaches the sensor position, the sensor sends a signal, the first drive device or the second drive device stops, and the corrugated steel sheet undercoat forming machine or the corrugated steel wall panel undercoat forming machine is precisely positioned in the working position.

[0117] Several of the aforementioned color steel tile sheet forming machines 31 and several color steel wall panel forming machines 32 are respectively equipped with pulleys 34 that match the guide rails 33 (e.g., Figure 8 (As shown).

[0118] like Figure 8 As shown, the color steel tile sheet forming machine 31 includes a first movable base at the bottom, and the color steel wall panel forming machine 32 includes a second movable base 35 at the bottom. The bottom of the first movable base and the second movable base are respectively provided with pulleys 34 that cooperate with the guide rail 33 on the ground. In use, the first driving device drives the first movable base to move along the guide rail 33, and the second driving device drives the second movable base to move along the guide rail 33, thereby driving the color steel tile sheet forming machine 31 or the color steel wall panel forming machine 32 to move along the guide rail.

[0119] The positioning component in this embodiment has multiple methods, and several positioning methods are listed below:

[0120] The first method involves installing a first sensor and a second sensor at the target position of the lower plate forming station. A first trigger block is installed at the bottom of the color steel tile lower plate forming machine 31. When the color steel tile lower plate forming machine 31 reaches the target position, the first trigger block triggers the first sensor. A second trigger block is installed at the bottom of the color steel wall panel lower plate forming machine 32. When the color steel wall panel lower plate forming machine reaches the target position, the second trigger block triggers the second sensor. During use, the positioning components can be switched according to the product production requirements.

[0121] The second method: A third sensor is set at the target position of the lower plate forming station 3, and a third trigger block is set on the color steel tile lower material forming machine 31; a fourth trigger block is set on the color steel wall panel lower material forming machine 32. When the color steel tile lower material forming machine 31 or the color steel wall panel lower material forming machine 32 reaches the target position, the third trigger block or the fourth trigger block triggers the sensor.

[0122] It should be noted that when the first, second, and third sensors are photoelectric switches, the first, second, third, and fourth trigger blocks are light-blocking plates; when the first, second, and third sensors are proximity switches, the first, second, third, and fourth trigger blocks are metal sheets.

[0123] When a change in production specifications is required, taking the target forming machine as the color steel tile sheet forming machine 31, and the color steel wall panel sheet forming machine 32 parked at the target location as an example: The second drive device is activated, and the color steel wall panel sheet forming machine 32 moves along the guide rail 33, moving out of the working center position of the sheet forming station 3. Simultaneously, the color steel tile sheet forming machine 31 moves along the guide rail 33 towards the target location until the first sensor on the color steel tile sheet forming machine 31 detects the first trigger block fixed at the station. The first sensor then sends a signal to the control device, which immediately cuts off the power to the first drive device corresponding to the color steel tile sheet forming machine 31, thus precisely stopping the color steel tile sheet forming machine 31 at the target location.

[0124] like Figure 5 and Figure 6 As shown, the corrugated steel sheet underbody forming machine 31 includes several first forming die units arranged side by side, used to progressively roll out the guide strips 15 (such as...) required for the corrugated steel sheet underbody on a flat steel strip. Figure 3(As shown); the first forming die unit includes a first upper die and a first lower die; the first upper die is provided with a plurality of first upper rollers 315, and the first upper rollers 315 are provided with a plurality of convex rollers 311. It should be noted that the shape of the convex rollers 311 is determined according to the cross-sectional shape and size of the target guide convex strip, which is prior art in the art and will not be described in detail here; the first lower die is correspondingly provided with a plurality of first lower rollers 316, and the first lower rollers 316 are provided with a plurality of concave rollers 312, and the concave rollers 312 are provided with forming grooves 313 that match the convex rollers of the first upper die. The plurality of first upper rollers and the plurality of first lower rollers are connected to a third drive device 314 through a belt drive system, and the convex rollers 311 and the roller group 312 are driven by the third drive device to realize synchronous rotation. The method of synchronously driving the first upper rollers and the first lower rollers through the belt drive system is prior art and will not be described in detail here.

[0125] In use, the flat steel strip passes between the relatively rotating first upper die and the first lower die. Through the step-by-step and continuous rolling of multiple sets of convex rollers 311 and multiple sets of concave rollers 312, the flat steel strip is gradually cold-bent into shape, thereby efficiently pressing several parallel guide strips 15 on its surface, thus forming the required color steel tile sheet material.

[0126] like Figure 7 As shown, the color steel wall panel underbody forming machine 32 includes several second forming die units arranged side by side, used to roll out the required shape of the color steel wall panel underbody on a flat steel strip. For example, it is usually necessary to press out interfaces on both sides of the color steel wall panel underbody for overlapping with another color steel wall panel underbody. The second forming die unit includes several first upper forming rollers 321 and several first lower forming rollers 322. The first upper forming rollers 321 and several first lower forming rollers 322 are connected to a fourth drive device 323 through a belt conveyor system, and are driven by the fourth drive device to achieve synchronous rotation of the first upper forming rollers 321 and the first lower forming rollers 322. During operation, the space between the first upper forming rollers 321 and the first lower forming rollers 322 is the forming space, used for the flat steel strip to pass through and be formed. The first upper forming rollers 321 and the first lower forming rollers 322 gradually press the flat steel strip into the color steel wall panel underbody under the power of the drive device.

[0127] like Figure 8 As shown, the second forming die unit further includes a first lifting device 324 for driving the first upper forming roller to rise or fall; and / or a second lifting device for driving the first lower forming roller to rise or fall.

[0128] like Figure 10 and Figure 11As shown, the color steel plate forming machine 51 includes several third forming mold units arranged side by side, used to roll out the required shape of the color steel plate 11 on the flat steel strip. For example, it is usually necessary to press out interfaces on both sides of the color steel plate 11 for connection with another color steel plate. The third forming mold unit includes several second upper forming rollers 511 and several second lower forming rollers 512. The second upper forming rollers 511 and the second lower forming rollers 512 are connected to the fifth drive device 513 through a belt conveyor system. During operation, the space between the second upper forming rollers 511 and the second lower forming rollers 512 is the forming space, used for the flat steel strip to pass through and be formed. Under the power of the fifth drive device, the second upper forming rollers 511 and the second lower forming rollers 512 gradually press the flat steel strip into a color steel plate.

[0129] Example 2: Lower Plate Forming Station

[0130] To accommodate the limited width of the production line, this design still allows for the switching of a small number of wall panel forming machines or roof tile forming machines to share the same workstation. This invention arranges two or more different specifications of color steel wall panel forming machines in one row, and simultaneously arranges two or more different specifications of color steel roof tile forming machines in one row. This layout ensures that the forming station only has two parallel forming machine modules: one for color steel wall panel forming machines and one for color steel roof tile forming machines. Each movement simply requires swapping the positions of these two modules. The overall width occupied is relatively small, and moving to the desired position is more convenient compared to multiple parallel forming machines.

[0131] like Figure 8 and Figure 9 As shown, the lower plate forming station includes a color steel wall panel lower material forming machine module 36 and a color steel tile lower material forming machine module. The color steel wall panel lower material forming machine module 36 is composed of several color steel wall panel lower material forming machines arranged in a row, and the color steel tile lower material forming machine module is composed of several color steel tile lower material forming machines arranged in a row.

[0132] This embodiment illustrates a color steel wall panel underlay forming machine module 36 consisting of two different specifications of color steel wall panel underlay forming machines 32 arranged in a row, and its usage.

[0133] The color steel wall panel undercoat forming machine module 36 is composed of a first color steel wall panel undercoat forming machine 361 and a second color steel wall panel undercoat forming machine 362 arranged in a row. The first color steel wall panel undercoat forming machine 361 and the second color steel wall panel undercoat forming machine 362 are arranged sequentially. In use, when the production line needs to produce color steel wall panel blanks using the first color steel wall panel blank forming machine 361, the first upper forming roller 321 on the second color steel wall panel blank forming machine 362 is raised or the first lower forming roller 322 on the second color steel wall panel blank forming machine 362 is lowered. This increases the height of the space between the first upper forming roller 321 and the first lower forming roller 322 on the second color steel wall panel blank forming machine 362. As a result, the color steel wall panel blank 13 formed by the first color steel wall panel blank forming machine 361 is not formed when passing through the second color steel wall panel blank forming machine 362. At this time, the first lower forming roller 322 of the second color steel wall panel blank forming machine 362 is equivalent to a conveyor roller and only performs the function of conveying. Similarly, when the production line needs to use the second color steel wall panel lower profile forming machine 362 to produce color steel wall panel lower profile 13, the first upper forming roller 321 on the first color steel wall panel lower profile forming machine 361 can be raised or the first lower forming roller 322 on the first color steel wall panel lower profile forming machine 361 can be lowered. This method is convenient to adjust and is suitable for production lines with relatively long spaces.

[0134] It should be noted that the usage of the corrugated steel sheet undercoat forming machine module is the same as that of the corrugated steel wall panel undercoat forming machine module 36, and will not be repeated here.

[0135] Example 3: Lower Plate Forming Station

[0136] The color steel sandwich panel production line in this embodiment is wide enough to accommodate multiple forming machines arranged side by side.

[0137] The lower plate forming station 3 includes several corrugated steel sheet lower material forming machines 31 arranged side by side and several corrugated steel wall panel lower material forming machines 32 arranged side by side, a guide rail 32 set on the ground of the station, and several driving devices for driving the corrugated steel sheet lower material forming machine 31 or the corrugated steel wall panel lower material forming machine 32 to slide along the guide rail 33.

[0138] Example 4: Lower Plate Forming Station

[0139] In this embodiment, when the width of the lower plate forming station is moderate and the length of the production line is moderate, the color steel sandwich panel production line can be laid out by mixing the color steel wall panel lower material forming machine module 36 and color steel tile lower material forming machine module of embodiment 2 with the color steel tile lower material forming machine 31 and color steel wall panel lower material forming machine 32 of embodiment 3.

[0140] Specific combination methods include:

[0141] Method 1: Several corrugated steel sheet undercoat forming machines 31 arranged side by side and several corrugated steel wall panel undercoat forming machine modules 36 arranged in a row; or,

[0142] Method 2: Several corrugated steel wall panel forming machines 32 arranged side by side and several corrugated steel roof tile forming machine modules arranged in a row; or;

[0143] Method 3: Several color steel roofing sheet forming machine modules arranged in a row, several color steel wall panel forming machine modules 36 arranged in a row, and several color steel wall panel forming machines 32 arranged side by side; or;

[0144] Method 4: Several color steel roofing sheet forming machine modules arranged in a row, several color steel wall panel forming machine modules arranged in a row, and several color steel roofing sheet forming machines 31 arranged side by side; or;

[0145] Method 5: Several color steel tile sheet under-material forming machine modules arranged in a row, several color steel wall panel under-material forming machine modules arranged in a row, several color steel wall panel under-material forming machines 32 arranged side by side, and several color steel tile sheet under-material forming machines 31 arranged side by side.

[0146] The layout of this embodiment allows for flexible arrangement of the lower plate forming station, which can be configured according to a specific production line.

[0147] Example 5

[0148] like Figure 8 and Figure 13 As shown, in this embodiment of the color steel sandwich panel production line, a first embossing station 6 is also provided between the lower plate uncoiling station 2 and the lower plate forming station 3. The first embossing station 6 includes a first embossing machine 61, which includes a first upper embossing roller 611 and a first lower embossing roller 612, as well as driving devices for driving the first upper embossing roller 611 and the first lower embossing roller 612 to rotate. When embossing is required, the first upper embossing roller 611 and the first lower embossing roller 612 with a specific pattern are selected. The flat steel strip passes between the first upper embossing roller 611 and the first lower embossing roller 612 and is pressed into a specific pattern under the power of the driving device.

[0149] like Figure 12As shown, in this embodiment of the color steel sandwich panel production line, a second embossing station 7 is also provided between the upper plate uncoiling station 4 and the upper plate forming and adhesive application station 5. The second embossing station 7 includes a second embossing machine 71, which includes a second upper embossing roller 711 and a second lower embossing roller 712, as well as driving devices for driving the second upper embossing roller 711 and the second lower embossing roller 712 to rotate. When embossing is required, the second upper embossing roller 711 and the second lower embossing roller 712 with a specific pattern are selected. The flat steel strip passes between the second upper embossing roller and the second lower embossing roller and is pressed into a specific pattern under the power of the driving device.

[0150] In actual production, embossing can be selected based on customized requirements. If embossing is required, a suitable embossing roller can be selected according to the actual requirements.

[0151] Example 6 Core Material Conveying Station

[0152] like Figures 14-17 As shown, the color steel sandwich panel production line of this embodiment also includes a core material conveying station 8 for conveying core materials.

[0153] The core material conveying station 8 is located on the side of the upper plate forming and adhesive application station 5. The core material conveying station 8 is equipped with two plate feeding machines to address the problem of insufficient core board width: given that the factory-made core boards are typically small, while the finished color steel sandwich panels require wider core materials, two core boards need to be fed between the upper and lower color steel plates 11 for bonding. In the traditional method, the ends of the two core boards are flush, resulting in low flexural strength of the finished product at that point. The design goal of this embodiment is to overcome this technical challenge by optimizing the core board conveying method and relative position setting.

[0154] The core material conveying station 8 includes a first plate feeding machine 81, a second plate feeding machine 82, a first suction cup device 83, a second suction cup device 84, a first plate conveyor 85, a grooving machine 86, and a second plate conveyor 87.

[0155] The first board feeding machine 81 and the second board feeding machine 82 are respectively used to transport the first core board and the second core board to the core board waiting area 88, which is located on the side of the first board conveyor 85.

[0156] The first suction cup device 83 is used to pick up the first core board conveyed by the first board feeding machine 81 and place it on one side of the first board conveyor 85;

[0157] The second suction cup device 84 is used to pick up the second core board conveyed by the second plate feeding machine 82 and place it on the other side of the first plate conveyor 85; the grooving machine 86 is set behind the first plate conveyor 85 and is used to groove the first core board and / or the second core board so as to cooperate with the color steel upper plate 11 and / or the color steel lower plate; it should be noted that the grooving machine is prior art and will not be described in detail here.

[0158] The second sheet material conveyor 87 is used to transport the slotted first and second core boards to the upper plate forming and adhesive application station 5 (e.g., ...). Figure 4 (As shown).

[0159] To further optimize structural strength, a first baffle 871 is provided in the middle of the side of the second sheet conveyor 87 away from the upper sheet forming and adhesive application station 5 to limit the second core board. A second baffle 872 is provided in the rear end of the second sheet conveyor 87 near the upper sheet forming and adhesive application station 5 to limit the first core board.

[0160] Its working process is as follows:

[0161] The second core board is stopped by the first baffle 871 on the second sheet material conveyor 87, while the first core board continues to be conveyed forward until it is blocked by the second baffle 872. This limiting mechanism ensures that the ends of the first and second core boards are non-parallel and staggered when they are conveyed to the upper plate forming and adhesive application station 5. When multiple sets of core boards enter the upper plate forming and adhesive application station 5 in sequence, a staggered splicing structure is formed between adjacent core boards, thereby effectively improving the bending resistance of the final formed color steel sandwich panel.

[0162] In actual production, the first core board and the second core board are usually stacked on the first board placement machine 81 and the second board placement machine 82, respectively. Because their dimensions are different, the number of boards in each stack also differs. For example, core boards with dimensions of 3000mm×350mm×50mm are typically stacked in stacks of 10, while core boards with dimensions of 3000mm×600mm×50mm are typically stacked in stacks of 8.

[0163] In traditional processes, two core boards are typically picked up simultaneously using the same suction cup device. To facilitate this simultaneous use, the heights of the first and second stacks of core boards must be leveled. This operation requires two workers, one specifically responsible for leveling the smaller stack with padding to ensure both stacks are at the same height. This method not only consumes manpower and increases labor intensity but also reduces the automation level and efficiency of the production line.

[0164] If the first board feeding machine and the second board feeding machine alternately feed the first core board and the second core board, respectively, then the first board feeding machine 81 and the second board feeding machine 82 need to frequently lift and lower to feed the material piece by piece. This not only makes the control system complex, but also easily leads to an increased equipment failure rate and higher overall operating costs.

[0165] Therefore, this utility model employs a first suction cup device 83 and a second suction cup device 84, respectively, for independently gripping the first core board and the second core board located on the core board waiting area 88. The core board waiting area 88 is equipped with a material detection device, which can monitor in real time whether there is a core board in the core board waiting area.

[0166] Specifically, when a suction cup device removes the last core board from the core board stack, the material detection device detects the disappearance of pressure in that area, indicating that there is no core board left at that location, and then sends a signal to the control system. Upon receiving the signal, the control system drives the corresponding board feeding machine to continue conveying the next stack of core boards, thereby achieving automated continuous feeding. This effectively solves the board picking control problem caused by inconsistent raw material stack heights, and improves production stability and efficiency.

[0167] Example 7 Upper plate pressing and adhesive application station

[0168] like Figures 18-21 As shown, the upper plate forming and adhesive application station of the color steel sandwich panel production line in this embodiment includes a color steel upper plate forming machine 51 for forming a color steel upper plate 11 by pressing a flat steel strip into a color steel upper plate 11 and an adhesive application device. The adhesive application device is used to apply adhesive to the upper surface of the color steel upper plate and the lower surface of the color steel lower plate / the upper surface of the core material.

[0169] The upper plate pressing and adhesive application station includes:

[0170] The color steel upper plate forming machine 51 is located above the upper plate forming and adhesive application station;

[0171] The color steel upper plate conveying roller 54 is set above the upper plate forming and adhesive application station and is used to convey the color steel upper plate;

[0172] The color steel lower plate conveying roller 55 is located below the upper plate forming and adhesive application station and is used to convey the color steel lower plate.

[0173] The core material conveying roller 56 is located in the middle of the upper plate forming and adhesive application station and is used to convey the first core board and the second core board.

[0174] The adhesive application device is used to drip or apply adhesive A and adhesive B onto the upper surface of the upper color steel plate and the lower surface of the lower color steel plate, and to apply them evenly; or, it is used to drip or apply adhesive A and adhesive B onto the upper surface of the upper color steel plate and the upper surface of the core material, and to apply them evenly; or, it is used to mix adhesive A and adhesive B and spray them evenly onto the upper surface of the upper color steel plate and the lower surface of the lower color steel plate; or, it is used to mix adhesive A and adhesive B and spray them evenly onto the upper surface of the upper color steel plate and the upper surface of the core material.

[0175] The upper plate pressing and adhesive application station in this embodiment integrates upper plate pressing, multi-material conveying (conveying color steel upper plate, core material and color steel lower plate) and adhesive application functions into a single station. Its structure is compact and adopts a three-dimensional layered layout, which greatly reduces the footprint of the equipment. At the same time, this structure makes the process efficient, realizes the seamless connection of multiple processes, reduces intermediate transfers, and improves production efficiency and automation level.

[0176] Example 8 Adhesive Application Device

[0177] The adhesive application device is a reciprocating sprayer, which is located on one side of the color steel upper plate forming machine 51.

[0178] The reciprocating spraying machine includes a first support body 521. The first support body 521 is provided with an A-adhesive pipe 522, a B-adhesive pipe 523, a first air pipe 524, and a composite nozzle 525. The composite nozzle 525 is provided with an A-adhesive inlet 5251, a B-adhesive inlet 5252, an air inlet 5253, and a mixing chamber 5254. The A-adhesive pipe 522 is connected to the A-adhesive inlet 5251 on the composite nozzle, the B-adhesive pipe 523 is connected to the B-adhesive inlet 5252 on the composite nozzle, the first air pipe 524 is connected to the air inlet 5253 on the composite nozzle, and the mixing chamber 5254 is provided with a mixing structure for mixing A-adhesive and B-adhesive.

[0179] The A-type adhesive pipe 522 is equipped with a first solenoid valve 5221, the B-type adhesive pipe 523 is equipped with a second solenoid valve 5231, and the first air pipe 524 is equipped with a third solenoid valve 5241 and a throttle valve 5242 connected in parallel. It should be noted that in this embodiment of the reciprocating spraying machine for color steel sandwich panels, when adhesive needs to be sprayed onto the lower material of the color steel panel, the composite nozzle faces downwards; when adhesive needs to be sprayed onto the upper material of the color steel panel, the composite nozzle faces upwards.

[0180] During production, the first solenoid valve 5221 and the second solenoid valve 5231 are open, the third solenoid valve 5241 is closed, and the throttle valve 5242 is open. Under the pump pressure of their respective pipelines, adhesive A and adhesive B flow through the open first solenoid valve 5221 and second solenoid valve 5231 to the compounding nozzle 525. Compressed air generated by the compressor enters the compounding nozzle 525 through the throttle valve. It should be noted that the throttle valve 5242 is designed to limit airflow and pressure, ensuring a suitable and stable value. During production, the compressed air entering the mixing chamber collides and mixes with the adhesive within, simultaneously breaking the mixed adhesive into fine mist particles, ultimately providing the propulsion for forward spraying. When production stops, the first solenoid valve 5221 and the second solenoid valve 5231 are closed, the third solenoid valve 5241 is open, and the throttle valve 5242 is closed. At this time, the A and B adhesives stop being fed into the mixing chamber. Simultaneously, compressed air enters the composite nozzle 525 directly, at high speed and with a large flow rate through the third solenoid valve 41. This is used to quickly spray the remaining two-component adhesive inside the composite nozzle onto the upper or lower material of the color steel plate, preventing the two-component adhesive from solidifying in the mixing chamber after it stops flowing, thus ensuring that the composite nozzle will not be blocked when the machine is started up next time.

[0181] The first solenoid valve 5221 and the second solenoid valve 5231 are designed so that when the production line encounters a fault, the first solenoid valve and the second solenoid valve close and stop the liquid supply. This can prevent the glue liquid from continuing to be supplied to the adhesive and avoid problems such as glue liquid backflow or air mixing into the pipeline.

[0182] It should be noted that in this embodiment, the first solenoid valve 5221, the second solenoid valve 5231, and the third solenoid valve 5241 are directly connected to the PLC on the color steel sandwich panel production line to achieve fully automatic control. When a system malfunction occurs, multiple valves can be simultaneously closed within seconds through PLC control, preventing continuous leakage of adhesive and avoiding significant waste. Simultaneously, it will not cause a serious imbalance in the mixing ratio of adhesive A and adhesive B.

[0183] The A-adhesive pipe 522 is also equipped with a first controllable speed regulating valve 5222; the B-adhesive pipe 523 is also equipped with a second controllable speed regulating valve 5232. Before production, the mixing ratio of A-adhesive and B-adhesive is tested, and the flow rates of the A-adhesive pipe and the B-adhesive pipe are set by the first controllable speed regulating valve 5222 and the second controllable speed regulating valve 5232. The setting of the first controllable speed regulating valve 5222 and the second controllable speed regulating valve 5232 ensures that when the production line is restarted after a shutdown, A-adhesive and B-adhesive are always supplied at a specific flow rate, so that the mixing ratio of A-adhesive and B-adhesive entering the composite nozzle is constant, and there will be no problems such as discontinuous adhesive, glue breakage, or mixing ratio deviation, which will ultimately affect the bonding quality.

[0184] The reciprocating spraying machine further includes a first detection element 5261, a second detection element 5262, and a fifth trigger block 5263. The first detection element 5261 and the second detection element 5262 are mounted on the first support body 521. The fifth trigger block 5263 moves synchronously with the composite nozzle 525. In use, the fifth trigger block 5263 sequentially triggers the first detection element 5261 and the second detection element 5262, thereby precisely controlling the spray origin and spray endpoint of the nozzle, and thus controlling the spraying range of the composite nozzle 525. In this embodiment, the fifth trigger block 5263 is mounted on the connector 5214, and the first detection element 5261 and the second detection element 5262 are mounted on a linear slide rail.

[0185] When adjusting the width, it is only necessary to adjust the installation position of the first detection element 5261 and the second detection element 5262 on the first bracket body 521. After installation, the first detection element 5261 and the second detection element 5262 are fixed on the first bracket body 521, and the fifth trigger block 5263 moves together with the nozzle.

[0186] The first detection element 5261 and the second detection element 5262 are both photoelectric sensors, and the fifth trigger block 5263 is a baffle.

[0187] The first support body 521 is provided with a telescopic arm 5211 and a first drive mechanism for controlling the linear movement of the telescopic arm. The front end of the telescopic arm 5211 is provided with the composite nozzle 525.

[0188] It should be noted that there are various drive mechanisms for controlling the linear movement of the telescopic arm. For example, the first drive mechanism includes a linear slide rail 5212, a timing belt 5213, a connecting member 5214, and a motor 5215 that drives the timing belt 5213 to rotate. The connecting member 5214 is fixed to the timing belt 5213, and a slider 5216 is provided below the connecting member 5214. The slider 5216 can slide relative to the linear slide rail 5212. The upper part of the connecting member 5214 is fixed to the telescopic arm 5211. During operation, the motor 5215 starts, driving the drive pulley to rotate, which in turn drives the timing belt 5213 to move. The movement of the timing belt 5213 causes the connecting member 5214 to slide along the linear slide rail, while simultaneously driving the telescopic arm 5211 to move linearly. It should be noted that in this embodiment, the connecting member 5214, the fifth trigger block 5263, and the slider 5216 can be integrated into one unit during processing.

[0189] The composite nozzle 525 includes a connector 5256 and a nozzle body 5257. The nozzle body 5257 is provided with the mixing chamber. The connector 5256 is provided with an A-glue inlet 5251, a B-glue inlet 5252, and an air inlet 5253. The connector 5256 and the nozzle body 5257 are detachably connected.

[0190] It should be noted that there are several ways in which the connector 5256 and the nozzle body 5257 can be detachably connected:

[0191] In one embodiment, the connector 5256 and the nozzle body 5257 are threadedly connected.

[0192] In another embodiment, the connector and the nozzle body are snap-fitted together;

[0193] In another embodiment, the connector and the nozzle body are connected by fasteners (nuts and bolts).

[0194] The mixing structure is a spiral mixing structure, which consists of a spiral blade 5255. The spiral blade 5255 and the mixing chamber form a spiral mixing chamber. Under the drive of compressed air, the A-liquid and B-liquid are mixed. The A-liquid, B-liquid and gas are repeatedly divided, sheared and recombine when flowing through the spiral blade 5255, thereby achieving thorough mixing.

[0195] In another embodiment, the hybrid structure is a spiral pipe.

[0196] The mixing structure described in this embodiment can, in principle, be a mixing structure that utilizes fluid kinetic energy to achieve thorough mixing. This embodiment employs a spiral mixing structure, which, with the assistance of compressed gas, achieves thorough mixing. It is low in cost and simple in structure.

[0197] The first support body 521 is equipped with a toolbox 527 for storage.

[0198] It should be noted that the installation position of the composite nozzle in this embodiment is adjustable. Installation grooves are provided on all four sides of the telescopic arm of the aluminum profile. When it is necessary to bond the upper material of the color steel sandwich panel to the core material, the liquid outlet of the composite nozzle is installed facing upwards (e.g., Figure 18 (As shown); When bonding the lower material of the color steel sandwich panel to the core material, the composite nozzle should be installed with the liquid outlet facing downwards (as shown). Figure 19 (As shown).

[0199] Example 8 Adhesive Application Device

[0200] The adhesive application device includes an adhesive applicator and an adhesive spreading device. The adhesive applicator is located in the middle of the upper plate pressing and adhesive application station, and is used to drip or apply adhesive A and adhesive B onto the upper and lower color steel plates or core plates. The glued upper and lower color steel plates and core material are then laminated in the subsequent lamination station, ultimately bonding the upper color steel plate, core material, and lower color steel plate together to form a complete color steel sandwich panel. It should be noted that the adhesive applicator is prior art, for example, Chinese patent document CN104874521A, and will not be described further here.

[0201] The adhesive mixing device 53 is located in the middle of the upper plate pressing and adhesive application station, and is used to mix adhesive A and adhesive B into a two-component adhesive.

[0202] like Figures 22-24 As shown, the adhesive application device 53 of the color steel sandwich panel production line in this embodiment includes a second support body 531. The support body 531 is equipped with a mounting frame 532 for mounting an adhesive application strip 534, a second drive mechanism 533 for driving the mounting frame to move horizontally, and an adhesive application strip 534 mounted on the mounting frame 5322. The second drive mechanism 533 drives the adhesive application strip 534 to reciprocate linearly along the width direction of the color steel panel. The adhesive application strip 534 is a silicone strip made of silicone material. The coating surface of the adhesive application strip 534 is a flat plane, which is beneficial for applying adhesive A and adhesive B. The adhesive application strip 534 can be obtained commercially. It should be noted that two sets of adhesive application devices are installed on the production line, respectively used for coating the upper and lower materials of the color steel panel. In use, when applying adhesive to the top layer of the color steel sheet, the adhesive-applying surface of the adhesive strip 534 is set upwards. The second drive mechanism 533 drives the mounting frame 532 to reciprocate linearly, thereby causing the adhesive-applying strip 534 to reciprocate linearly along the width direction of the top layer of the color steel sheet, so as to evenly apply adhesive A and adhesive B. Similarly, when applying adhesive to the bottom layer of the color steel sheet, the coating surface of the adhesive strip 534 is set downwards. The drive mechanism 533 drives the mounting frame 532 to reciprocate linearly, thereby causing the adhesive-applying strip 534 to reciprocate linearly along the width direction of the bottom layer of the color steel sheet, so as to evenly apply adhesive A and adhesive B.

[0203] In this embodiment, the second driving mechanism 533 can drive the adhesive strip 534 to reciprocate linearly along the width direction of the color steel plate in several ways. Four of these methods are listed below:

[0204] Method 1: The second drive mechanism 533 includes a drive motor 5331 and a crank-connecting rod mechanism; the output shaft of the drive motor is connected to the crank 5332 of the crank-connecting rod mechanism, and the connecting rod 5333 of the crank-connecting rod mechanism is hinged to the mounting frame 532 to convert the rotational motion of the drive motor into the reciprocating linear motion of the mounting frame 532.

[0205] Method 2: The drive mechanism includes a drive motor, an eccentric wheel, a rocker arm, and a connecting rod. One end of the rocker arm is hinged to the bracket body, and the other end is hinged to the eccentric wheel. One end of the connecting rod is hinged to the eccentric wheel, and the other end is hinged to the mounting frame. The rotational motion of the eccentric wheel is converted into the reciprocating linear motion of the mounting frame, and then into the direct reciprocating motion of the rubber strip.

[0206] The mounting bracket 532 includes a first mounting plate 53211 and a second mounting plate 53212. The first mounting plate 53211 and the second mounting plate 53212 are respectively provided with oblong holes. The applicator strip 534 is provided with corresponding oblong holes. In use, a fixing component (e.g., a wing nut) 535 passes sequentially through the second mounting plate 53212, the applicator strip 534, and the first mounting plate 53211, thereby fixing the applicator strip to the mounting bracket 532. The oblong holes allow adjustment of the position of the applicator strip, ensuring that both adhesive A and adhesive B can be applied.

[0207] The second support body 531 is also equipped with a third lifting device 536 for controlling the up and down movement of the mounting frame 532. When it is necessary to wipe the adhesive strip, simply raise the mounting frame 532 to move the adhesive strip away from the steel plate to be coated, and then the operator can wipe the adhesive strip without having to remove it. It is convenient to use, and the overall wiping time is very short, which can avoid the problem of the entire color steel plate being scrapped due to the interruption of adhesive application.

[0208] To further optimize the problem in traditional spin coaters where the lifting mechanism driving the spin coater needs to move horizontally along with the spin coater, this embodiment adopts a split-type design for the mounting bracket. In the prior art, the cylinder and its air pipe driving the spin coater need to perform horizontal reciprocating motion along with the spin coater. This makes the air pipe prone to friction with the surrounding supports, leading to severe wear and affecting its service life. To solve this problem, the mounting bracket in this embodiment adopts a split-type design for the active support and the transmission support. Specifically, it includes the following design:

[0209] The mounting bracket 532 includes an active bracket 5321 and a transmission bracket 5322. The active bracket 5321 is provided with the first mounting plate 53211 and the second mounting plate 53212. The active bracket 5321 is connected to the second drive mechanism 533, which is used to drive the glue strip 534 to perform a horizontal reciprocating glue application motion. The transmission bracket 5322 is connected to the third lifting device 536. A rotating structure 5323 is provided between the active bracket 5321 and the transmission bracket 5322, allowing the active bracket 5321 to move horizontally relative to the transmission bracket 5322, thereby separating the horizontal glue application motion from the vertical lifting motion.

[0210] The rotating structure 5323 includes a first rotating member 53231 mounted on the active support 5321 with a first shaft and sleeved on the first shaft, and a second rotating member 53232 mounted on the transmission support 5322 with a second shaft and sleeved on the second shaft. The first rotating member 53231 and the second rotating member 53232 are connected together, thereby separating the lifting movement of the third lifting device 536 from the horizontal movement of the uniform adhesive strip driven by the drive mechanism. In use, the third lifting device 536 controls the transmission support 22 to move up and down, thereby driving the active support 21 to move up and down accordingly.

[0211] The third lifting device 536 includes a cylinder 5361 and a second air pipe 5362, and the piston rod of the cylinder 5361 is connected to the transmission bracket 5322.

[0212] The uniform adhesive strip 534 is provided with a shearing opening 5341 to facilitate the uniform passage of adhesive A and adhesive B.

[0213] In summary, the adhesive applicator for color steel sandwich panels in this embodiment uses silicone strips for the adhesive applicator strips, which makes cleaning the adhesive applicator strips particularly convenient. When two-component adhesive is attached to the adhesive applicator strips, the attached material can be removed by simply wiping it, reducing the material and labor costs caused by frequently replacing disposable foam strips or sound insulation cotton.

[0214] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
