Description

Technical Field

[0001] This invention belongs to the field of board processing technology, and specifically relates to a film coating device for rock wool board production. Background Technology

[0002] Rock wool board coating is used to prevent moisture intrusion, avoid moisture absorption and efflorescence that could lead to reduced insulation performance and corrosion of surrounding components, and also to fix the mineral fibers, preventing fiber detachment during construction and use. Rock wool board coating mainly includes three methods: manual coating, hot-applied coating, and cold-press coating, to suit different production scales and precision requirements.

[0003] For example, in the prior art (Chinese patent with publication number CN118952689B), a film coating device for rock wool board production is disclosed. It adopts a hot-adhesive film coating method. Through the structural design of a reciprocating mechanism, a scraper, and a glue collection box, the reciprocating mechanism is driven by a sprocket drive. The scraper moves back and forth to scrape away the glue accumulated on the edge of the coating roller, avoiding glue waste. At the same time, it can achieve the operation of scraping glue evenly, improving the uniformity of glue coating. The glue collection box effectively collects the scraped glue, preventing glue from contaminating the conveyor belt, reducing maintenance costs, extending the service life of the conveyor belt, and improving production efficiency.

[0004] The cold-pressing laminating equipment for rock wool board production transports the rock wool board and film to the laminating station during operation. Stable pressure is applied to the bonding surfaces of the film and rock wool board using pressure rollers. Through mechanical extrusion, the film, which is pre-coated with room-temperature curing adhesive, is tightly bonded to the rock wool board, thus achieving the laminating process.

[0005] However, the aforementioned rock wool board cold-pressing and laminating equipment uses a combination of intermittent conveying and stop-and-cutting to achieve die-cutting. This means the film cutting process requires a simultaneous pause in the conveying system, utilizing the time window created by interrupting continuous board conveying to allow the cutter to descend and cut. This process results in stoppages in the laminating process, leading to poor process continuity. Compared to continuous conveying laminating solutions, it reduces processing efficiency per unit time and is prone to causing board positioning deviations due to frequent start-stop cycles, affecting laminating and cutting accuracy and product consistency. Summary of the Invention

[0006] To address the problems of existing rock wool board coating processes, such as downtime, poor process continuity, reduced processing efficiency per unit time compared to continuous conveyor coating solutions, and frequent start-stop cycles leading to board positioning deviations that affect coating cutting accuracy and product consistency, this invention provides a rock wool board coating device. This device uses the rock wool board's own conveying motion to trigger the film cutting action, eliminating the need to interrupt the conveying process or set up additional downtime. This ensures seamless connection between continuous coating of multiple rock wool boards and subsequent film cutting processes, improving processing efficiency per unit time, while avoiding positioning deviations caused by frequent start-stop cycles, optimizing coating cutting accuracy and product consistency. Furthermore, it simplifies equipment control logic and extends the service life of traditional frequently start-stop components. The specific technical solution is as follows:

[0007] A film-coating device for producing rock wool boards is used for film-coating processing by pressing a film onto the surface of a rock wool board. It further includes: a conveying device, a linkage system, and a film-cutting system. Two sets of conveying devices are arranged correspondingly on the left and right sides to convey a plurality of rock wool boards at equal intervals from left to right. Two sets of linkage systems are arranged correspondingly on the front and rear sides of the upper surface of the right-side conveying device. The film-cutting system is located between the two sets of conveying devices and is used to cut the film on the rock wool board after film coating.

[0008] Under the premise that the conveying device continuously and without interruption, the linkage system is triggered by the conveying movement of the rock wool board itself after the film is covered, so as to automatically realize the film cutting system tilting and descending to cut the film.

[0009] In the above technical solution, each group of the linkage system includes: a first mounting base, a through groove, a first strip groove, a drive pin, a first moving rod, a moving arm, a first sleeve, a sliding plate, a first spring, a second sleeve, a second moving rod, a second spring, a fixing block, and an inclined surface. The first mounting base is fixedly installed on the upper surface edge of the conveying device; the through groove is opened through the middle of the first mounting base along the width direction of the first mounting base; the first strip groove is inclinedly opened on the upper surface of the first mounting base and communicates with the inner cavity of the through groove; the drive pin is slidably embedded in the inner cavity of the first strip groove; the first moving rod is slidably embedded in the inner cavity of the through groove, and the drive pin is fixed and vertically installed on the first moving rod; the first sleeve and the moving arm are sequentially fixedly installed on the end of the first moving rod, and the first sleeve is horizontally... A through cavity is provided in the direction of the rock wool board. The movable arm is slidably disposed on the right side wall of the rock wool board. A sliding plate is slidably sleeved on the first movable rod and disposed inside the first mounting base. A first spring is sleeved on the first movable rod and its two ends are respectively fixedly connected to the sliding plate and the side wall of the first mounting base. A second mounting base is slidably sleeved on the movable arm. The second movable rod slides horizontally through the left side wall of the first mounting base and is fixedly connected to the left side wall of the second mounting base. A second spring is sleeved on the second movable rod and its two ends are respectively fixedly connected to the left side wall of the first mounting base and the left end of the second movable rod. A fixing block is fixedly installed on the inner side wall of the first mounting base. An inclined surface is inclinedly disposed on the side wall of the fixing block, and the first mounting base is slidably sleeved on the fixing block.

[0010] In the above technical solution, when the rock wool board moves to the right and the linkage system is linked to achieve the downward cutting of the film cutting system, the first sleeve is driven to gradually be fitted onto the fixed block along the outer wall of the inclined surface, so that the rock wool board displacement drives the moving arm to gradually detach from the side wall of the rock wool board.

[0011] In the above technical solution, the inclination angle of the first strip groove is the same as that of the inclined surface.

[0012] In the above technical solution, the film cutting system includes: a second mounting base, a second strip groove, a slide rod, a connecting rod, a mounting plate, a tension spring, a mounting arm, a cutter, a drive frame, a first connecting arm, and a second connecting arm. Two sets of the second mounting base are arranged correspondingly at the front and rear. Two sets of the second strip groove are obliquely and parallelly penetrating the second mounting base. The slide rods are slidably embedded within the cavities of the two sets of the second strip grooves. The connecting rods are fixedly installed at the ends of the two sets of slide rods. Two sets of the mounting plate are vertically arranged correspondingly at the front and rear. The two ends of the tension spring are respectively connected to the top of the side wall of the mounting plate and the side wall of the connecting rod. Multiple sets of mounting arms are provided, with their top ends fixedly installed on the slide rods. The cutter is installed at the bottom of the multiple sets of mounting arms. Two sets of drive frames are provided, slidably sleeved on the two sets of slide rods correspondingly at the front and rear, and each set of drive frames has a rectangular cavity penetrating from front to back. The first connecting arm is fixedly installed on the right side wall of each set of drive frames. The second connecting arm is fixedly installed on the right end of the first connecting arm and fixedly connected to the left end of the second moving rod.

[0013] In the above technical solution, the bottom end of the cutter is configured with a serrated shape.

[0014] The above technical solution also includes four sets of corrective conveying components. Each pair of corrective conveying components is symmetrically inclined about the horizontal central axis of the conveying device. Each set of corrective conveying components includes: a U-shaped seat, a first rotating shaft, a rotating roller, a conveyor belt, and a micro motor. Two sets of first rotating shafts are provided and are rotatably disposed in the inner cavity of the U-shaped seat. The rotating rollers are fixedly installed on the two sets of first rotating shafts. The conveyor belt is sleeved on the two sets of rotating rollers, and its sidewall is in relative rotatable contact with the sidewall of the rock wool board. The micro motor is installed on the lower surface of the U-shaped seat, and its output end is connected to one of the sets of first rotating shafts.

[0015] The conveyor belt rotates relative to the direction of travel of the rock wool board.

[0016] In the above technical solution, the inclination angle between the conveyor belt and the side wall of the rock wool board is set to 5°-15°.

[0017] The above technical solution also includes an adjustment system, which comprises: a vertical plate, a first guide rod, an adjusting arm, a crossbar, a second guide rod, a fixed seat, a first cylinder, a drive rod, and a connecting rod. Four sets of vertical plates are vertically arranged. The first guide rods are fixedly installed between two corresponding sets of vertical plates along the front-rear direction. Two sets of adjusting arms are arranged, symmetrically slidably mounted on each set of first guide rods, and the U-shaped seat is fixedly installed on the adjusting arm. The crossbar is installed horizontally between two corresponding sets of adjusting arms. The second guide rod is fixedly installed between the two sets of first guide rods. The fixed seat is fixedly installed on the second guide rod. The first cylinder is installed on the fixed seat. The drive rod is installed at the output end of the first cylinder and is parallel to the first guide rod. Two sets of connecting rods are symmetrically arranged around the middle of the drive rod, and both ends of each set of connecting rods are rotatably connected to the drive rod and the adjusting arm, respectively.

[0018] The above technical solution also includes: a drive system, a rolling assembly, and a PLC controller. The drive system and the rolling assembly are disposed between the two sets of conveying devices, and the rolling assembly is disposed above the drive system. The membrane is attached to the upper surface of the rock wool board under the action of the drive system and the rolling assembly. The PLC controller is installed on the drive system and is used to control electrical components.

[0019] The rock wool board production coating device of the present invention has the following advantages compared with the prior art:

[0020] I. Addressing the issues of poor process continuity, low processing efficiency, and frequent start-stop cycles causing board positioning deviations that affect lamination and cutting accuracy and product consistency in existing lamination equipment, this invention employs a continuous conveying method. Under continuous conveying of rock wool boards along the conveying device, the natural conveying displacement of the lamination-completed rock wool boards triggers a linkage system, thereby driving the film cutting system to perform automated film cutting. This invention achieves the linkage triggering of the film cutting action through the rock wool board's own conveying motion, eliminating the need to interrupt the conveying process or set additional stop intervals. This ensures seamless connection between continuous lamination of multiple rock wool boards and subsequent film cutting processes, improving processing efficiency per unit time. It also avoids rock wool board positioning deviations caused by frequent start-stop cycles, optimizing lamination and cutting accuracy and product consistency. Furthermore, it simplifies equipment control logic and extends the service life of traditional frequently start-stop components.

[0021] II. In this invention, the moving arm of the linkage system, under the pushing action of the rock wool board that has been coated, moves to the right along the conveying direction and simultaneously releases the limiting constraint on the side wall of the rock wool board. When the moving arm moves to the gap area of ​​the next set of adjacent rock wool boards with the conveying rhythm, it automatically resets to the initial position, completing the linkage trigger cycle and preparing for the subsequent film cutting process of the coated rock wool board. This invention achieves an automated cycle of triggering, displacement, and reset by directly driving the moving arm through the conveying displacement of the rock wool board. This allows the linkage system to repeatedly perform film cutting linkage on the continuously conveyed rock wool board. The linkage process is highly coordinated with the continuous conveying rhythm of the rock wool board, ensuring seamless connection between the coating and film cutting processes, further enhancing the efficiency of continuous processing, and helping to steadily increase the processing capacity per unit time. In addition, the pure mechanical linkage structure does not rely on electronic signal transmission and control. The triggering timing is precisely determined by the actual displacement of the rock wool board, avoiding the film cutting timing deviation caused by signal delay or interference, and significantly improving the accuracy of the film cutting position.

[0022] Third, this invention achieves linkage through the rock wool board driven linkage system after film coating, which drives the cutter in the film cutting system to perform film cutting action in an inclined downward posture, instead of using a vertical falling film cutting method; this inclined film cutting method can significantly reduce the relative displacement between the cutter and the continuously horizontally conveyed film, effectively avoiding the long tear defect of film that is easily caused by vertical cutting, which can not only ensure a smooth cut, but also reduce the risk of film stretching damage to the rock wool board, and enhance the stability and reliability of the film cutting process;

[0023] Fourth, in the process of covering and conveying rock wool boards on the conveying device, the present invention adds a corrective conveying component for limiting and correcting the travel direction of the rock wool boards. On the one hand, by guiding and standardizing the travel trajectory of the rock wool boards, it effectively avoids the problems of misalignment of the covering and cutting deviation caused by the offset during the conveying process, thus ensuring processing accuracy. On the other hand, it simultaneously provides auxiliary pushing power, reduces the frictional resistance between the rock wool boards and the conveying device, and improves the smoothness and stability of the conveying. The corrective conveying component has both guiding and limiting and auxiliary pushing functions. The integrated dual-function design eliminates the need for additional dedicated guiding or pushing devices, simplifying the equipment structure.

[0024] V. In this invention, the two sets of straightening conveyor components arranged in front of and behind the rock wool board are both inclined relative to the side wall of the rock wool board. Specifically, the inclination angle between the conveyor belt in the straightening conveyor component and the side wall of the rock wool board is set to 5°-15°. This angle range can accurately guide and push the rock wool board, ensuring conveying stability. It can also provide reasonable tolerance space through the inclined structure when the rock wool board enters between the two sets of straightening conveyor components with a slight inclination, avoiding entry obstruction caused by the initial posture deviation of the rock wool board. At the same time, this angle range can ensure that the conveyor belt rotates normally to push the rock wool board, effectively avoiding the problem of rock wool board jamming caused by excessive inclination angle, improving the smoothness of equipment operation, and further ensuring the efficient advancement of continuous coating processing.

[0025] VI. In this invention, two sets of corrective conveying components are arranged in a corresponding manner at both the feeding station before and the discharge station after the rock wool board is coated. The corrective conveying components before coating can pre-correct and precisely guide the rock wool board to ensure that it enters the coating station in a standardized posture. The corrective conveying components after coating can continuously maintain the positive conveying state of the rock wool board, avoiding the impact of positional deviation on processing quality during the coating process. This dual-point layout realizes the control of the position of the rock wool board before and after coating, forming a closed-loop guiding guarantee from feeding to discharge, improving the accuracy of the coating position and product consistency, and reducing material waste caused by positional deviation, laying the foundation for the precise execution of the subsequent film cutting process.

[0026] VII. This invention achieves synchronous adjustment of the relative spacing between two sets of corresponding correction conveying components through an adjustment system. Specifically, the adjustment system links the relative positions of the two sets of correction conveying components arranged at two points, maintaining a symmetrical distribution of the two sets of components relative to the horizontal centerline of the conveying device throughout the adjustment process. This method not only adapts to rock wool boards of different widths, ensuring that the rock wool boards can still be centered, corrected, and pushed after adjustment, guaranteeing the positional accuracy of processes such as lamination and cutting, but also achieves synchronous adjustment of the two-point correction conveying components through the same adjustment mechanism. This simplifies the operation process, improves adjustment convenience, and strictly ensures that the adjustment range of each correction conveying component is consistent, avoiding guide imbalance caused by deviations in a single set of adjustments. This further enhances the equipment's adaptability and processing stability for rock wool boards of different specifications, reducing operational difficulty and debugging costs.

[0027] In summary, this invention employs a continuous conveying and mechanically linked film-cutting design to replace the traditional intermittent stop mode, achieving seamless connection between film coating and film cutting, improving processing efficiency per unit time, avoiding positioning deviations caused by frequent start-stop cycles, optimizing product consistency, and simplifying control logic while extending equipment life. The pure mechanically linked cyclic structure relies on the precise triggering of film cutting based on the displacement of the sheet material conveying, avoiding electronic signal interference. Combined with an inclined film cutting method, it reduces the relative displacement between the cutter and the film, avoiding tearing defects, ensuring a smooth cut, and reducing the risk of sheet material damage. The integrated dual-function corrective conveying component, through a specific angled inclined arrangement and a closed-loop layout of dual-point inlet and outlet, combines guiding and limiting functions with auxiliary pushing functions. This avoids conveying jamming and deviation while ensuring that the sheet material is conveyed in the center throughout the entire process, improving processing accuracy and reducing material waste. The adjustment system achieves symmetrical linkage adjustment of the dual-point guiding components, easily adapting to sheets of different widths, ensuring adjustment consistency, enhancing processing stability, reducing operation and debugging costs, and fully meeting the needs of continuous, high-precision, and multi-specification film coating processing.

[0044] The following are specific implementation cases and appendices. Figures 1 to 15 The present invention will be further described, but the present invention is not limited to these embodiments.

[0045] A film-coating device for producing rock wool boards is used for pressing a film 2 onto the surface of a rock wool board 1. It further includes a conveying device 3, a linkage system 4, and a film-cutting system 5. Two sets of conveying devices 3 are arranged on the left and right sides respectively, conveying several rock wool boards 1 at equal intervals from left to right. Specifically, multiple rock wool boards 1 are conveyed and arranged at equal intervals on the conveying device 3 by manual labor or existing mature robotic arms. This is achieved using existing common technical means, and will not be elaborated or limited here. The conveying device 3 adopts a commercially mature conveying device, which mainly consists of a power system, conveyor rollers, conveyor belts, and other core components. It falls within the scope of existing technology and only needs to meet the conveying function requirements of the rock wool boards 1; therefore, no further elaboration or limitation is made here. The linkage system 4 is set in two sets, which are respectively set on the front and rear sides of the upper surface of the right conveyor device 3; the film cutting system 5 is set between the two sets of conveyor devices 3 and is used to cut the film body 2 after the rock wool board 1 is covered with film; wherein, under the premise that the conveyor device 3 continuously conveys without interruption, the linkage system 4 is triggered by the conveying movement of the rock wool board 1 after the film is covered, and the film cutting system 5 is automatically realized to tilt down and cut the film body 2.

[0046] This invention innovatively employs a continuous conveying process. When the rock wool board 1 is continuously conveyed along the conveying device 3, the natural conveying displacement of the rock wool board 1 after film coating directly triggers the linkage system 4, which in turn drives the film cutting system 5 to automatically perform the film cutting operation. This design achieves the linkage triggering of the film cutting action through the conveying motion of the rock wool board 1 itself, without interrupting the conveying process or setting additional stop intervals. On the one hand, it ensures seamless connection between the continuous film coating of multiple rock wool boards 1 and the subsequent film cutting process, significantly improving the processing efficiency per unit time. On the other hand, it effectively avoids the positioning deviation problem of the rock wool board 1 caused by frequent start-stop, optimizing the film coating and cutting accuracy and product consistency. At the same time, it simplifies the equipment control logic, reduces the wear and tear of traditional frequently start-stop components, and extends the service life of key equipment components.

[0047] For details, please refer to the main references. Figure 2 , Figure 3 , Figure 5 , Figures 6 to 9As shown, each linkage system 4 includes: a first mounting base 401, a through groove 402, a first strip groove 403, a drive pin 404, a first moving rod 405, a moving arm 406, a first sleeve 407, a sliding plate 408, a first spring 409, a second sleeve 410, a second moving rod 411, a second spring 412, a fixing block 413, and an inclined surface 414. The first mounting base 401 is fixedly mounted on the edge of the upper surface of the conveying device 3; the through groove 402 runs along the first mounting base 401. A through-slot 403 is formed in the middle of the first mounting base 401 in the width direction; a first strip-shaped groove 403 is inclinedly formed on the upper surface of the first mounting base 401 and communicates with the inner cavity of the through-slot 402; a drive pin 404 is slidably embedded in the inner cavity of the first strip-shaped groove 403; a first moving rod 405 is slidably embedded in the inner cavity of the through-slot 402, and the drive pin 404 is fixed and vertically installed on the first moving rod 405. Under the joint limiting of the first strip-shaped groove 403 and the through-slot 402, the drive pin 404 can drive the first moving rod 405. A movable rod 405 slides along the trajectory of the inner cavity of the through groove 402 in an inclined direction; a first sleeve 407 and a movable arm 406 are sequentially fixedly installed at the end of the first movable rod 405, and the first sleeve 407 has a through cavity in the horizontal direction. The movable arm 406 is relatively slidably disposed on the right side wall of the rock wool board 1, that is, the movable arm 406 slides relative to the side wall of the rock wool board 1 at different positions in different states; a sliding plate 408 is slidably sleeved on the first movable rod 405, and is provided with The first spring 409 is sleeved on the first moving rod 405 and its two ends are fixedly connected to the sliding plate 408 and the side wall of the first sleeve 407, respectively. When the moving arm 406 and the first sleeve 407 move towards the through groove 402, the first spring 409 is forced to compress. Conversely, the elastic force of the first spring 409 can push the first moving rod 405, the first sleeve 407 and the moving arm 406 to return to the position away from the through groove 402. The second sleeve 410 is slidably sleeved on the movable arm 406; the second movable rod 411 slides horizontally through the left side wall of the first mounting base 401 and is fixedly connected to the left side wall of the second sleeve 410; the second spring 412 is sleeved on the second movable rod 411 and its two ends are fixedly connected to the left side wall of the first mounting base 401 and the left end of the second movable rod 411, respectively; the fixing block 413 is fixedly installed on the inner side wall of the first mounting base 401; the inclined surface 414 is inclinedly arranged on the side wall of the fixing block 413, and the first sleeve 407 is slidably sleeved on the fixing block 413.

[0048] The coated rock wool board 1 is conveyed to the right by the conveying device 3, adhering to the moving arm 406 and driving it to move synchronously, thereby driving the second sleeve 410 and the second moving rod 411 to move and compress the second spring 412. At the same time, the moving arm 406 carries the first sleeve 407 to the inclined side wall of the inclined surface 414, where the fixing block 413 is sleeved and tilted away from the rock wool board 1, releasing the limit.

[0049] In this invention, the moving arm 406 in the linkage system 4, pushed by the completed film-coated rock wool board 1, moves to the right and gradually disengages from the limiting position on the side wall of the rock wool board 1. When it reaches the gap between the next set of adjacent rock wool boards 1, the moving arm 406 automatically resets to its original position, preparing for the next linkage of the next set of film-coated rock wool boards 1. That is, in this invention, the linkage system 4 can repeatedly play a linkage role in the film-cutting process of the film-coated rock wool board 1. Moreover, this linkage role is driven by the displacement of the film-coated rock wool board 1. The triggering timing of the purely mechanical linkage is more accurate, with no signal transmission delay, which is more conducive to ensuring the accuracy of the film-cutting timing. Furthermore, the repeated linkage role of a set of linkage systems 4 allows the linkage system 4 to repeatedly play a film-cutting linkage role on the continuously conveyed rock wool board 1. This linkage process is highly coordinated with the continuous conveying rhythm of the rock wool board 1, ensuring seamless connection between the film-coating and film-cutting processes, and further enhancing the efficiency of continuous processing.

[0050] For details, please refer to the main references. Figures 7 to 9 As shown, when the rock wool board 1 moves to the right, the linkage system 4 drives the film cutting system 5 to cut downwards at an angle. This causes the first sleeve 407 to gradually mount onto the fixed block 413 along the outer wall of the inclined surface 414, thus displacing the rock wool board 1 and driving the moving arm 406 to gradually detach from the side wall of the rock wool board 1. After film cutting is completed, the two sets of moving arms 406 detach from the right side wall of the rock wool board 1 and abut against its front and rear side walls. Once the rock wool board 1 is completely detached, the elastic forces of the second spring 412 and the first spring 409 respectively drive the second sleeve 410 and the first sleeve 407 to reset, causing the moving arm 406 to return to its initial position, preparing for the next trigger.

[0051] For details, please refer to the main references. Figure 8 As shown, the first slot 403 is inclined at the same angle as the inclined surface 414 to ensure that during the displacement of the drive pin 404 along the inner cavity of the first slot 403, the first sleeve 407 is displaced at the same angle along the outer wall of the inclined surface 414. This ensures that the first moving rod 405, the moving arm 406, and the first sleeve 407 move at the same amplitude and that there is no twisting or tilting between them.

[0052] For details, please refer to the main references. Figures 4 to 6 , Figure 10As shown, the film cutting system 5 includes: a second mounting base 501, a second strip groove 502, a slide rod 503, a connecting rod 504, a mounting plate 505, a tension spring 506, a mounting arm 507, a cutter 508, a drive frame 509, a first connecting arm 510, and a second connecting arm 511. Two sets of the second mounting base 501 are arranged correspondingly at the front and rear. Two sets of the second strip groove 502 are obliquely and parallelly penetrating the second mounting base 501. The slide rod 503 is slidably embedded within the inner cavity of the two sets of second strip grooves 502. The connecting rod 504 is fixedly installed at the ends of the two sets of slide rods 503. The mounting plate 505 is vertically arranged correspondingly at the front and rear. Two sets of springs; the two ends of the tension springs 506 are respectively connected to the top of the side wall of the mounting plate 505 and the side wall of the connecting rod 504; multiple sets of mounting arms 507 are provided, and the top ends are fixedly installed on the slide rod 503; the cutter 508 is installed at the bottom of the multiple sets of mounting arms 507; two sets of drive frames 509 are provided, which are respectively slidably sleeved on the two sets of slide rods 503 in front and behind, and each set of drive frames 509 has a rectangular inner cavity extending from front to back; the first connecting arm 510 is fixedly installed on the right side wall of each set of drive frames 509; the second connecting arm 511 is fixedly installed on the right end of the first connecting arm 510 and is fixedly connected to the left end of the second moving rod 411.

[0053] During the displacement of the second moving rod 411 driven by the rock wool board 1, the second moving rod 411 moves to the right in conjunction with the second connecting arm 511 and the drive frame 509, pushing the slide rod 503 to move along the inner cavity of the second strip groove 502. This causes the mounting arm 507 and the cutter 508 to move down along the inclined path and stretch the tension spring 506. Finally, the cutter 508 cuts the film 2 on the left edge of the rock wool board 1, realizing the automated film cutting of the rock wool board 1 after film covering by triggering the linkage system 4 and the film cutting system 5. In addition, the second moving rod 411 returns to its original position with the elastic force of the second spring 412 and moves to the left in conjunction with the second connecting arm 511 and the drive frame 509. Under the synergistic effect of the tension spring 506, the connecting rod 504, the slide rod 503, the mounting arm 507, and the cutter 508 move up and return to their original position along the inclined path of the second strip groove 502, preparing for the next set of film cutting operations on the left side of the rock wool board 1 after film covering.

[0054] In this invention, the linkage of the rock wool board 1 after film coating and the linkage system 4 is used to enable the cutter 508 in the film cutting system 5 to cut the film in an inclined downward manner, rather than directly triggering the cutter 508 to fall vertically to cut the film. Compared with the method of directly cutting the film in the vertical direction, the method of this invention can reduce the relative displacement between the vertical cutting of the cutter 508 and the film that is still moving horizontally, and avoid the cutter 508 from making long tear cuts on the film.

[0055] For details, please refer to the main references. Figure 6As shown, the bottom end of the cutter 508 is designed with a serrated structure. This serrated design enables the cutter 508 to quickly pierce the membrane 2. With the help of the continuously distributed sharp serrated shape, the opening gradually expands after piercing the membrane 2, thereby achieving instantaneous cutting of the membrane 2 and ensuring the efficiency of the cutting action and the integrity of the cut.

[0056] For details, please refer to the main references. Figure 3 , Figure 4 , Figure 11 , Figure 12 As shown, it also includes four sets of straightening conveying assemblies 6. Each pair of straightening conveying assemblies 6 is symmetrically arranged at an angle about the horizontal central axis of the conveying device 3. Each set of straightening conveying assemblies 6 includes: a U-shaped seat 601, a first rotating shaft 602, a rotating roller 603, a conveyor belt 604, and a micro motor 605. Two sets of first rotating shafts 602 are provided, each rotatably mounted within the U-shaped seat 601 via bearings. The rotating rollers 603 are fixedly mounted on the two sets of first rotating shafts 602. The conveyor belt 604 is sleeved on the two sets of rotating rollers 603, with its sidewall in relative rotatable contact with the sidewall of the rock wool board 1. The rotating rollers 603 and conveyor belt 604 are commercially available models, and their standard fit enables synchronous rotation of the two sets of rotating rollers 603. In practical applications, it is only necessary to ensure that the two maintain relatively synchronized rotational motion within the design tolerance range, ultimately stably driving the conveyor belt 604 to rotate. There is no need to impose special limitations on its specific model, specifications, or additional performance parameters. This selection not only meets the usage requirements of this application but also reduces design and procurement costs by relying on mature general-purpose components, while simplifying subsequent maintenance procedures. Its specific structural details will not be elaborated here. The micro motor 605 is mounted on the lower surface of the U-shaped base 601, and its output end is connected to one of the first rotating shafts 602.

[0057] When the activated micro motor 605 drives the first rotating shaft 602 connected to its output end to rotate, the two sets of rotating rollers 603 are rotated by the transmission of the conveyor belt 604. The conveyor belt 604 rotates relative to the direction of travel of the rock wool board 1. Specifically, the conveyor belts 604 in the two sets of straightening conveyor assemblies 6 located behind the horizontal central axis of the conveying device 3 rotate counterclockwise to apply a rightward thrust to the rear wall of the rock wool board 1; the conveyor belts 604 in the two sets of straightening conveyor assemblies 6 located in front of the horizontal central axis of the conveying device 3 rotate clockwise to apply a rightward thrust to the front wall of the rock wool board 1.

[0058] In this invention, two sets of corrective conveying components 6 are provided at the work station before the rock wool board 1 is coated and at the discharge position after the rock wool board 1 is coated. These components can respectively ensure that the rock wool board 1 is corrected and guided before entering the coating process, and ensure that it continues to move in the positive direction during the coating process. The corrective conveying components 6 with dual positions can ensure that the rock wool board 1 is kept in the accurate conveying position before and after the coating process, thereby ensuring the accuracy of the subsequent coating position.

[0059] For details, please refer to the main references. Figure 3 As shown, the inclination angle between the conveyor belt 604 and the side wall of the rock wool board 1 is set to 5°-15°. This angle range can accurately guide the movement trajectory of the rock wool board 1 and realize the pushing function, ensuring stable conveying; it can also provide error tolerance for the initial slight inclination of the rock wool board 1 to avoid obstruction; at the same time, it can ensure that the conveyor belt 604 rotates and pushes normally, avoiding jamming problems caused by excessive angle, improving the smoothness of equipment operation, and ensuring the efficient progress of continuous coating processing.

[0060] For details, please refer to the main references. Figure 2 , Figure 4 , Figure 11 As shown, it also includes an adjustment system 7, which includes: a vertical plate 701, a first guide rod 702, an adjusting arm 703, a horizontal bar 704, a second guide rod 705, a fixed seat 706, a first cylinder 707, a drive rod 708, and a connecting rod 709. The vertical plate 701 has four sets of vertically arranged components. The first guide rods 702 are fixedly installed between two corresponding sets of vertical plates 701 along the front-rear direction. Two sets of adjusting arms 703 are provided, and are symmetrically slidably sleeved on each set of first guide rods 702. A U-shaped seat 601 is fixedly installed on the adjusting arm 703. Rod 704 is installed horizontally between two sets of corresponding adjusting arms 703; second guide rod 705 is fixedly installed between two sets of first guide rods 702; fixed seat 706 is fixedly installed on second guide rod 705; first cylinder 707 is installed on fixed seat 706; drive rod 708 is installed at the output end of first cylinder 707 and is arranged parallel to first guide rod 702; two sets of connecting rods 709 are symmetrically arranged about the middle of drive rod 708, and the two ends of each set of connecting rods 709 are rotatably connected to drive rod 708 and adjusting arm 703 respectively through pins.

[0061] The first cylinder 707 is activated to drive the drive rod 708 to move, which in turn drives two sets of symmetrical linkage rods 709, thereby driving the corresponding adjusting arm 703 to slide along the outer wall of the first guide rod 702. When the right adjusting arm 703 moves, it is linked by the crossbar 704 to move the two sets of adjusting arms 703 on the left side in a synchronous manner, so as to realize the synchronous relative movement of the front and rear adjusting arms 703. This drives the two sets of straightening and conveying components 6 to precisely adjust the spacing until the conveyor belt 604 is tightly attached to the side wall of the rock wool board 1, laying a solid foundation for the subsequent straightening, guiding and conveying of the rock wool board 1.

[0062] By adjusting the system 7, this invention can synchronously adjust the relative spacing between the two sets of corresponding correction and conveying components 6. In other words, by adjusting the system 7, the relative positions of the two sets of correction and conveying components 6 with dual positions can be synchronously adjusted, ensuring symmetry with respect to the horizontal centerline of the conveying device 3 before and after adjustment. This ensures that rock wool boards 1 of different widths can be centered, corrected, and pushed before and after adjustment. Moreover, the same mechanism can adjust the correction and conveying components 6 with dual positions, which is more convenient and ensures the consistency of the adjustment range of each correction and conveying component 6.

[0063] For details, please refer to the main references. Figure 1 , Figures 13 to 15 As shown, this solution also includes: a drive system 8, a rolling assembly 9, and a PLC controller 10. The drive system 8 and the rolling assembly 9 are located between the two sets of conveying devices 3, with the rolling assembly 9 positioned above the drive system 8. Under the action of the drive system 8 and the rolling assembly 9, the membrane 2 is attached to the upper surface of the rock wool board 1. The PLC controller 10 is installed on the drive system 8 and is used to control the electrical components. Specifically, the PLC controller 10 can control the start and stop of the conveying device 3 and its running speed, the start and stop of the micro motor 605 and its output rotation speed, the start and stop of the first cylinder 707, the start and stop of the relevant circuits inside the housing 801, the start and stop of the stepper motor 807 and its output rotation speed, and the start and stop of the second cylinder 901 and its stroke speed, etc. In other words, the PLC controller 10 enables the normal operation and use of the various components in this solution. These are all existing technologies and will not be elaborated or limited here.

[0064] For details, please refer to the main references. Figure 1 , Figure 2 , Figures 13 to 15As shown, the drive system 8 includes: a housing 801, mounting blocks 802, a second rotating shaft 803, a first conveying roller 804, a first synchronous gear 805, a second synchronous gear 806, a stepper motor 807, a synchronous toothed belt 808, a first gear 809, a third rotating shaft 810, and a second gear 811. Two sets of mounting blocks 802 are arranged correspondingly at the front and rear of the housing 801, and the second mounting base 801 and mounting plate 805 are respectively fixedly mounted on the housing 801. Four sets of mounting blocks 802 are arranged, with each pair of blocks fixedly mounted in the inner cavity of the housing 801, corresponding to the left and right sides. The second rotating shaft 803 rotates through the housing 801 in the front-to-back direction. The outer wall of the mounting block 802 is fitted with a first conveying roller 804 fixedly mounted on a second rotating shaft 803; a first synchronous gear 805 fixedly mounted on the free end of the second rotating shaft 803; a stepper motor 807 is disposed within one of the housings 801; a second synchronous gear 806 is mounted on the output end of the stepper motor 807; a synchronous toothed belt 808 is meshed and sleeved on the first synchronous gear 805 and the second synchronous gear 806; the first synchronous gear 805, the second synchronous gear 806, and the synchronous toothed belt 808 are selected from commercially available synchronous belts and pulleys, achieving synchronous rotation of the two sets of synchronous pulleys through standard fit. In practical applications, it is only necessary to ensure that the above components maintain relatively synchronous rotation within the design tolerance range, ultimately stably driving the second rotating shaft 803 to rotate, without special limitations on their specific models, specifications, or additional performance parameters; this selection not only meets the usage requirements of this application but also reduces design and procurement costs by relying on mature general-purpose components, while simplifying subsequent maintenance procedures; its specific structural details will not be elaborated here. Two sets of first gears 809 are provided, each fixedly mounted on one of the two sets of second rotating shafts 803. A third rotating shaft 810 is rotatably connected to the inner cavity of one set of housings 801 via bearings. A second gear 811 is fixedly mounted on the third rotating shaft 810 and meshes with the side walls of both sets of first gears 809. When the equipment is in operation, the stepper motor 807 starts and drives the second synchronous gear 806 to rotate, which in turn drives the first synchronous gear 805 to rotate synchronously via the synchronous toothed belt 808. Through the meshing transmission between the second gear 811 and the two sets of first gears 809, the two sets of second rotating shafts 803 and the first conveyor roller 804 rotate synchronously clockwise.

[0065] For details, please refer to the main references. Figure 1 , Figure 2 , Figures 13 to 15As shown, the rolling assembly 9 includes: a second cylinder 901, a moving block 902, a fourth rotating shaft 903, and a second conveying roller 904. The second cylinder 901 is provided in four sets, with each pair of sets vertically mounted on the housing 801, corresponding to each other on the left and right sides. The moving block 902 is mounted on the output end of the second cylinder 901. The fourth rotating shaft 903 is rotatably connected to the side wall of the moving block 902 via bearings. The second conveying roller 904 is fixedly mounted on the fourth rotating shaft 903, and is vertically aligned with the first conveying roller 804. The rock wool board 1 passes between the second conveying roller 904 and the first conveying roller 804, and the membrane 2 is pressed against the upper surface of the rock wool board 1 during the relative rotation of the second conveying roller 904 and the first conveying roller 804. In this invention, the unwinding of the membrane 2 is achieved using an existing mature unwinding device, which falls within the scope of existing technology. Its core function is to ensure that the film body 2 is smoothly transported between the second conveying roller 904 and the first conveying roller 804, and to complete the film coating operation on the surface of the rock wool board 1. There is no need to impose additional restrictions on the specific structure of the film body 2 and the unwinding device. A conventional model that meets the above-mentioned usage requirements can be selected, which will not be elaborated here.

[0066] When the rock wool board 1 moves to the right under the drive of the conveying device 3, it drives the two sets of second conveying rollers 904 above to rotate counterclockwise, so that the second conveying rollers 904 and the first conveying rollers 804 form a relative rotational relationship, thereby automatically rolling and pressing the film 2 after the film is coated on the surface of the rock wool board 1 to ensure that the film and the board are tightly bonded.

[0067] Furthermore, the present invention uses a second cylinder 901 to drive a moving block 902 to perform vertical displacement, thereby enabling height adjustment of the second conveying roller 904. This design can flexibly adapt the height parameters of the second conveying roller 904 to meet the rolling requirements after coating of rock wool boards 1 of different thicknesses. Compared to the traditional processing method where the distance between the second conveying roller 904 and the first conveying roller 804 is fixed and can only accommodate the coating and rolling of rock wool boards 1 of a single thickness, this design broadens the applicability of the equipment and improves its versatility and adaptability in processing rock wool boards 1 of multiple specifications.

[0068] It is also worth noting that the first cylinder 707 and the second cylinder 901 used in this application are both commonly used self-locking cylinders on the market. Their output ends can stop at any position and lock. As long as they meet the usage requirements of this application, they will not be described or limited here. The micro motor 605 and the stepper motor 807 are both conventional motors on the market. Given that their performance parameters and functions are existing mature technologies and fully meet the usage requirements of this application, their specific power, speed and other parameters will not be further limited or described here.

[0069] In addition, the conveyor belt of the conveying device 3 in this invention does not adopt a fully enclosed structure, but is set as at least two sets of strip conveyor belts, which can rotate on rollers; this design not only ensures stable conveying of rock wool board 1, but also reserves sufficient space for the installation of adjustment system 7 and correction conveying assembly 6, taking into account both conveying reliability and equipment layout rationality.

[0070] The working principle of the rock wool board production coating device in this embodiment is as follows:

[0071] The front and rear corresponding correction and conveying components 6 are pre-positioned and adjusted so that the side wall edge of the conveyor belt 604 is in contact with the side wall of the rock wool board 1 to be coated: the first cylinder 707 is activated to drive the drive rod 708 to generate displacement, which in turn drives the two sets of symmetrically arranged linkage rods 709 to drive the corresponding connected adjusting arms 703 to slide along the outer wall of the first guide rod 702; when the right adjusting arm 703 moves, the linkage is achieved through the crossbar 704, so that the two sets of adjusting arms 703 on the left side generate corresponding displacements synchronously; this adjustment mechanism can realize the synchronous relative displacement of the front and rear corresponding adjusting arms 703, thereby driving the front and rear two sets of correction and conveying components 6 to complete the precise adjustment of the relative distance, until the front and rear two sets of conveyor belts 604 are in close contact with the side wall of the rock wool board 1, laying the foundation for the subsequent correction, guidance and conveying of the rock wool board 1;

[0072] When the equipment is working, the free end of the membrane 2 adheres to the right edge of the upper surface of the rock wool board 1 to be coated, and gradually covers the surface of the rock wool board 1 as it moves to the right. After the stepper motor 807 starts, it drives the second synchronous gear 806 to rotate, which in turn drives the first synchronous gear 805 to rotate synchronously via the synchronous toothed belt 808. Through the meshing transmission of the second gear 811 and the two sets of first gears 809, the two sets of second rotating shafts 803 and the first conveying rollers 804 rotate synchronously clockwise. When the rock wool board 1 moves to the right under the drive of the conveying device 3, the friction of the rock wool board 1 causes the two sets of second conveying rollers 904 above to rotate counterclockwise, so that the second conveying rollers 904 and the first conveying rollers 804 rotate relative to each other. Through the rolling action of the two, the membrane 2 is coated on the surface of the rock wool board 1, ensuring that the membrane 2 and the rock wool board 1 are tightly adhered.

[0073] After the film coating is completed, the rock wool board 1 continues to move to the right under the conveying action of the conveying device 3 until its right side wall edge is in contact with the side wall of the moving arm 406, and the moving arm 406 moves to the right synchronously. After being pushed, the moving arm 406 drives the second sleeve 410 and the second moving rod 411 to move in the same direction, causing the second spring 412 to be compressed and deformed; at the same time, the moving arm 406 moving to the right drives the first sleeve 407 on its outer wall to be gradually fitted onto the fixed block 413 along the inclined side wall of the inclined surface 414. During this process, the moving arm 406, the first sleeve 407, and the driving pin 404 all tilt and move along the preset direction of the first strip groove 403 until the moving arm 406 completely detaches from the right side wall of the film-coated rock wool board 1, releasing its limiting constraint. At the same time, during the displacement of the second moving rod 411, the second connecting arm 511, the first connecting arm 510, and the drive frame 509 move to the right in sync, driving the two sets of sliding rods 503 to move along the inner cavities of the two sets of second strip grooves 502 respectively, causing the mounting arm 507 and the cutter 508 to tilt downwards along the inclined path of the second strip groove 502. During this process, the tension spring 506 is stretched; until the cutter 508 cuts the film 2 on the left edge of the coated rock wool board 1, that is, the linkage system 4 is triggered by the coated rock wool board 1 to realize the automated film cutting of the film cutting system 5.

[0074] After the above-mentioned film cutting action is completed, the two sets of moving arms 406 lose the thrust of the right side wall of the rock wool board 1 and instead abut against the front and rear side walls of the rock wool board 1; until the side wall of the rock wool board 1 with the film completed is completely separated from the outer wall of the moving arm 406, the elastic force of the second spring 412 drives the second sleeve 410 to reset towards the direction of the second spring 412, and the elastic force of the first spring 409 causes the first sleeve 407 to gradually separate from the outer wall of the inclined surface 414, thereby pushing the moving arm 406 to reset to the initial position, preparing for the next set of rock wool board 1 with the film completed to move to the right and trigger the moving arm 406. In addition, when the second moving rod 411 is reset towards the direction of the second spring 412 by the elastic force of the second spring 412, it simultaneously drives the second connecting arm 511, the first connecting arm 510, and the drive frame 509 to move to the left; and under the synergistic action of the tension spring 506, it drives the connecting rod 504, the sliding rod 503, the mounting arm 507, and the cutter 508 to synchronously tilt upward along the inclined preset path of the second strip groove 502, thus preparing for the subsequent automatic film cutting operation of the left end of the next set of film-coated rock wool board 1 triggered by the linkage system 4.

[0075] Through the aforementioned mechanical linkage mechanism, the rock wool board 1 after film coating can precisely trigger the moving arm 406, thereby linking the cutter 508 to synchronously perform tilting and descending displacement, realizing automated tilting film cutting operation. The linkage system 4 constructs a closed-loop linkage structure of triggering, displacement, and reset, ensuring that the film cutting action is highly compatible with the conveying rhythm of the rock wool board 1, and guaranteeing the automation, precision, and continuity of the film cutting process.

[0076] This invention employs a continuous conveying and mechanically linked film cutting design, abandoning the traditional intermittent stop-and-go cutting mode. This ensures seamless connection between the laminating and cutting processes, improving processing efficiency per unit time, while avoiding positioning deviations caused by frequent start-stop cycles, optimizing product consistency, and simplifying control logic and extending the service life of key equipment components. The purely mechanically linked trigger, displacement, and reset cyclic structure relies on the sheet material's own conveying displacement to precisely trigger the film cutting action, avoiding electronic signal delays and interference, significantly improving the accuracy of the cutting position. Combined with an inclined cutting method, it effectively reduces the relative displacement between the cutter and the film, avoiding long tear defects in the film, ensuring a smooth and flat cut, and reducing the risk of sheet material damage. (Integrated...) The dual-function correction and conveying component 6 combines guiding and limiting functions with auxiliary pushing functions. While simplifying the equipment structure, its 5°-15° inclined arrangement and dual-point closed-loop layout for feeding and discharging provide reasonable tolerance space for the board's posture, avoiding conveying jams and deviations, and ensuring that the board is conveyed in a centered and positive direction throughout the entire process. This improves the accuracy of lamination and cutting, and reduces material waste. The adjustment system 7 enables symmetrical linkage adjustment of the dual-point guiding components, which not only conveniently adapts to boards of different widths and specifications, but also ensures consistent adjustment range, avoids guiding imbalance, enhances equipment processing stability, reduces operation and debugging costs, and fully meets the needs of continuous, high-precision, and multi-specification rock wool board lamination processing.

[0077] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
