Description

Technical Field

[0001] This invention belongs to the field of film application equipment technology, specifically relating to a processing equipment and working method for applying film to six sides of rock wool boards. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Rock wool has become an ideal thermal insulation material widely used in construction, industry, and other fields. However, rock wool products have revealed certain durability defects during actual transportation, storage, and long-term use. Due to its porous, hydrophilic fiber structure, the surface of rock wool is prone to fiber pulverization and shedding when exposed to the atmosphere for extended periods, and it also absorbs moisture from the air, leading to hygroscopicity. This significantly reduces the material's thermal insulation performance and, more importantly, adversely affects its crucial fire resistance performance—the presence of moisture may accelerate structural aging and affect its fire resistance integrity when exposed to fire, shortening the material's service life.

[0004] To address this issue, existing technologies commonly employ a composite protective layer on the rock wool surface. Among these, applying aluminum foil is currently the most common surface treatment method. This coating can, to some extent, prevent moisture intrusion and reduce direct exposure of surface fibers, thereby delaying the performance degradation of the rock wool. However, problems remain, such as uneven adhesion between the film and the rock wool substrate, incomplete sealing, and the inability to achieve automatic film application on all six sides. Summary of the Invention To address the aforementioned problems, this invention provides a processing equipment and method for applying film to six sides of rock wool boards, which solves the problems of uneven bonding strength between the film material and the rock wool substrate, incomplete coverage, and inability to achieve automatic film application on all six sides.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, the present invention provides a processing equipment for applying film to six sides of rock wool boards, comprising: a spray adhesive film-coating machine, a side film-coating machine, a flying saw, a reversing conveyor, and a film-coating and cutting machine, wherein a roller conveyor is provided between the spray adhesive film-coating machine, the side film-coating machine, the flying saw, the reversing conveyor, and the film-coating and cutting machine, and the rock wool boards are conveyed and transferred through the roller conveyor. The glue spraying and laminating machine includes a glue spraying frame with multiple conveying rollers arranged parallel to each other in the horizontal direction. Along the upper edge of the glue spraying frame in the feeding direction, a glue spraying cover, a glue spraying pipeline system, a membrane pressing roller, a membrane guide roller, and a membrane assembly are sequentially arranged. The rock wool board passes through the glue spraying cover, and the glue from the glue spraying pipeline system is sprayed onto the surface of the rock wool board through a fan-shaped nozzle assembly. The fan-shaped nozzle assembly consists of multiple fan-shaped nozzles and is fixedly installed in the glue spraying cover. The laminating film on the membrane assembly is adhered to the upper and lower surfaces of the rock wool board by the membrane guide roller and the membrane pressing roller.

[0006] As a further implementation, the adhesive spraying cover is divided into an upper adhesive spraying cover and a lower adhesive spraying cover; the adhesive spraying pipeline system is divided into an upper adhesive spraying pipeline system and a lower adhesive spraying pipeline system; the membrane pressing roller is divided into an upper membrane pressing roller and a lower membrane pressing roller; the membrane guide roller is divided into an upper membrane guide roller and a lower membrane guide roller; and the membrane assembly is divided into an upper membrane assembly and a lower membrane assembly. The upper adhesive spraying cover, the upper adhesive spraying pipeline system, the upper membrane pressing roller, the upper membrane guide roller, and the upper membrane assembly are sequentially arranged above the adhesive spraying frame along the feeding direction, and the lower adhesive spraying cover, the lower adhesive spraying pipeline system, the lower membrane pressing roller, the lower membrane guide roller, and the lower membrane assembly are sequentially arranged below the adhesive spraying frame along the feeding direction.

[0007] As a further implementation, the side-coating machine includes a frame, with a front pressure roller at one end of the top of the frame and a rear pressure roller at the other end. A length measuring wheel and a large pressure roller are provided at the end of the frame near the rear pressure roller. A side film assembly, a first guide wheel, a second guide wheel, a side film constraint block, and a side film heating block assembly are arranged sequentially on both sides of the top of the frame along the material travel direction, and are all arranged between the front and rear pressure rollers.

[0008] As a further implementation, the distances from the center points of the side membrane assembly, the first guide wheel, and the second guide wheel to the side of the rock wool board decrease sequentially.

[0009] As a further implementation, the flying saw includes a first frame, a second frame, a cutting assembly, a walking drive mechanism, and a tracking assembly. The cutting assembly includes a cutting saw blade, which is mounted on a cutting motor via a saw blade clamping assembly. The cutting motor is mounted on a guide slider assembly via a cutting motor mount, and the end of the slider assembly is fixed to the first frame. The first frame and the second frame are connected by the tracking assembly. A support plate for supporting the sheet metal is embedded in the first frame, and the support plate is located below the slider assembly. The walking drive mechanism is located on the first frame.

[0010] As a further implementation, the cutting and walking drive mechanism includes saw blade walking timing pulleys disposed at both ends of the slider assembly, and a saw blade walking timing belt surrounding the saw blade walking timing pulleys. The saw blade walking timing belt is fixedly connected to the cutting motor base through a timing belt pressure plate.

[0011] As a further implementation, the tracking component includes a tracking motor, a tracking timing pulley arranged back and forth along the material travel direction, a tracking timing belt surrounding the tracking timing pulley, a tracking slider assembly connected to the tracking timing belt, the tracking timing belt being fixedly connected to the first frame through a tracking timing belt pressure plate, and the tracking motor being connected to the tracking timing pulley and providing power to the tracking timing belt. As a further implementation, the reversing conveyor includes a reversing frame and a reversing tray; sliding units are respectively arranged on both sides of the reversing frame in the discharge direction, and trays are slidably arranged on the sliding units and driven by reversing cylinders; the moving direction of the reversing cylinders is perpendicular to the feeding direction in the horizontal plane, so as to receive materials from the flying saw; a conveying roller conveyor is arranged below the reversing tray, and the conveying direction of the conveying roller conveyor is perpendicular to the feeding direction in the horizontal plane, thereby realizing reversal.

[0012] As a further implementation, the cutter head is connected to the drive end of the cutting cylinder; an upper support plate is provided on the cutting frame, and the upper support plate is connected to the cutting frame through an upper support plate frame; an upper silicone plate is provided below the upper support plate, and the upper silicone plate is located below the cutter head to provide cushioning when the cutter head rises to perform the cutting action; a material support plate for supporting materials is provided below the upper silicone plate; the device also includes an encoder for providing a length signal, which is installed on the side laminating machine and controlled to the cutting cylinder so that the cutting action of the cutting cylinder corresponds to the gap position between adjacent rock wool boards.

[0013] Secondly, the present invention also provides a working method for a rock wool board six-sided film lamination processing equipment, comprising the following steps: Step 1: After cleaning, the rock wool board enters the glue spraying and laminating machine and is conveyed to the glue spraying area by the conveying roller. The fan-shaped nozzles of the upper and lower glue spraying pipeline system spray glue evenly on the upper and lower surfaces of the rock wool board. Then, the upper and lower films are pressed onto the upper and lower surfaces of the rock wool board by the upper film pressing roller and the lower film pressing roller, respectively. Step 2: The coated rock wool board enters the first side coating machine. The rock wool board is placed on the base plate and pushed forward by the subsequent board. The side film is guided by the side film assembly and is heated by the side film constraint block and the side film heating block assembly in sequence before being attached to one side of the rock wool board. It is then pressed by the rear pressure roller. At the same time, the length measuring wheel contacts the board and drives the encoder to record the conveying length of the board. Step 3: The rock wool board enters the flying saw station. The flying saw control unit identifies the gap of the board according to the length data provided by the encoder. When the gap moves to the bottom of the cutting saw blade, the tracking motor starts, so that the cutting saw blade moves synchronously with the board. At the same time, the travel motor drives the cutting saw blade to move laterally, cutting the upper and lower films and a set of side films on the upper and lower surfaces of the board vertically along the gap. Step 4: The cut rock wool board enters the reversing conveyor. The board is pushed onto the pallet, and then the reversing cylinder drives the reversing pallet to move to both sides, so that the rock wool board falls into the conveying rollers below, and the conveying direction becomes perpendicular to the board feeding direction. Step 5: After reversing, the rock wool board enters the second side laminating machine, and the side film is heated and applied to the other side of the rock wool board using the same method as in Step 3; Step Six: The rock wool board enters the film-coating and cutting machine. Based on the length data provided by the encoder, when the board moves to the cutting position through the gap, the cutting cylinder drives the cutter head to rise and cut the side film, thus completing the film application of the rock wool board.

[0014] Compared with the prior art, the advantages and positive effects of this invention are: The rock wool board six-sided wrapping and laminating equipment of this invention connects a spray adhesive laminating machine, a side laminating machine, a flying saw, a reversing conveyor, and a laminating and cutting machine in series via a roller conveyor. This achieves continuous and automated conveying and transfer of rock wool boards on the production line, significantly improving production efficiency and process continuity. The spray adhesive laminating machine uses a spray adhesive system composed of multiple fan-shaped nozzles, which can uniformly and quickly spray adhesive onto the upper and lower surfaces of the rock wool board and simultaneously complete the smooth lamination of the upper and lower surfaces, ensuring the stability of the lamination quality. Its step-by-step wrapping process is rationally designed, following the process of "first laminating the upper and lower surfaces, then laminating the two sides, reversing after the first cut, and finally laminating the remaining two sides," systematically fulfilling the complete requirements of six-sided lamination. The production line integrates the precise cutting of the flying saw and the automatic reversing function of the reversing conveyor, ensuring the consistency of board dimensions and the continuity of the process. Necessary manual intervention was retained in the processes of loading, unloading, and cutting the film edges. This avoided the need for manual pressing to address potential issues of incomplete bonding after the film was cut on the opposite side. This resulted in a flexible human-machine collaboration model that ensured both automation efficiency and quality control. Attached Figure Description

[0018] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0019] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof. Example 1 This embodiment provides a processing device for applying film to six sides of rock wool boards, such as... Figure 1 - Figure 12 As shown, the production line includes: a glue spraying and laminating machine 1, a side laminating machine 2, a flying saw 3, a reversing conveyor 4, and a laminating and cutting machine 5. A roller conveyor 7 is installed between the glue spraying and laminating machine 1, the side laminating machine 2, the flying saw 3, the reversing conveyor 4, and the laminating and cutting machine 5, conveying and transferring rock wool boards 6 via the roller conveyor 7. The roller conveyor 7 connects the glue spraying and laminating machine 1, the side laminating machine 2, the flying saw 3, the reversing conveyor 4, and the laminating and cutting machine 5 in series, achieving continuous automated conveying and transfer of rock wool boards 6 on the production line, improving production efficiency and process continuity. The process involves first laminating the top and bottom sides, then the two sides, performing an initial cut, reversing the direction, and finally laminating the remaining two sides, fulfilling the complete requirement of six-sided lamination. The production line integrates the precise cutting of the flying saw 3 and the automatic reversing function of the reversing conveyor 4, ensuring the consistency of board dimensions and the continuity of the process.

[0020] The adhesive spraying and laminating machine 1 includes an adhesive spraying frame 112. Multiple conveying rollers 111 are arranged parallel to each other in the horizontal direction on the adhesive spraying frame 112. Along the upper edge of the adhesive spraying frame 112 in the feeding direction, an adhesive spraying cover, an adhesive spraying pipeline system, a membrane pressing roller, a membrane guide roller, and a membrane assembly are sequentially arranged. The rock wool board 6 passes through the adhesive spraying cover, and the adhesive from the adhesive spraying pipeline system is sprayed onto the surface of the rock wool board 6 through a fan-shaped nozzle 113 assembly. The fan-shaped nozzle 113 assembly consists of multiple fan-shaped nozzles 113 and is fixedly installed in the adhesive spraying cover. The film on the membrane assembly is adhered to the upper and lower surfaces of the rock wool board 6 by the membrane guide roller and the membrane pressing roller. The adhesive spraying and laminating machine 1 uses an adhesive spraying system composed of multiple fan-shaped nozzles 113, which can uniformly and quickly spray adhesive onto the upper and lower surfaces of the rock wool board 6 and simultaneously complete the smooth adhesion of the film on both sides, ensuring the stability of the laminating quality.

[0021] As a further implementation, the adhesive spraying cover is divided into an upper adhesive spraying cover 107 and a lower adhesive spraying cover 108; the adhesive spraying pipeline system is divided into an upper adhesive spraying pipeline system 109 and a lower adhesive spraying pipeline system 110; the membrane pressing roller is divided into an upper membrane pressing roller 105 and a lower membrane pressing roller 106; the membrane guide roller is divided into an upper membrane guide roller 103 and a lower membrane guide roller 104; and the membrane assembly is divided into an upper membrane assembly 101 and a lower membrane assembly 102. The upper adhesive spraying cover 107, the upper adhesive spraying pipeline system 109, the upper membrane pressing roller 105, the upper membrane guide roller 103, and the upper membrane assembly 101 are sequentially arranged above the adhesive spraying frame 112 along the feeding direction. The lower adhesive spraying cover 108, the lower adhesive spraying pipeline system 110, the lower membrane pressing roller 106, the lower membrane guide roller 104, and the lower membrane assembly 102 are sequentially arranged below the adhesive spraying frame 112 along the feeding direction. By symmetrically arranging complete systems for spraying adhesive, pressing film, guiding, and film assembly at the top and bottom, the upper and lower surfaces of the rock wool board 6 can be coated simultaneously. This improves production efficiency and coating quality: simultaneous double-sided processing avoids the flipping process after single-sided operation, significantly enhancing the continuity and efficiency of the production line. Simultaneously, the symmetrical layout helps ensure consistent tension and alignment between the upper and lower coatings.

[0022] As a further implementation, the side-coating machine 2 includes a frame 211. A front pressure roller 201 is located at one end of the top of the frame 211, and a rear pressure roller 207 is located at the other end. A length-measuring wheel 208 and a large pressure roller 209 are located at the end of the frame 211 closest to the rear pressure roller 207. On both sides of the top of the frame 211, along the material travel direction, a side film assembly 202, a first guide wheel 203, a second guide wheel 204, a side film constraint block 205, and a side film heating block assembly 206 are sequentially arranged, all positioned between the front pressure roller 201 and the rear pressure roller 207. This completes the functional sequence of unfolding the film via the side film assembly 202 (guided and positioned by the first and second guide wheels 204), constraining and tidying it via the side film constraint block 205, and heating and bonding it via the side film heating block assembly 206. The stability and adhesion of the coating are ensured by the front and rear pressure rollers 207 and the large pressure roller 209, which ensure smooth material conveying and provide sufficient pressing force and shaping conditions for the side film. The measuring roller 208 facilitates precise control of the coating length.

[0023] As a further implementation, the distances from the center points of the side membrane assembly 202, the first guide wheel 203, and the second guide wheel 204 to the side of the rock wool board 6 decrease sequentially. By making the distances between the center points of the guide wheels and the side of the board decrease sequentially, the side membrane is guided to gradually and smoothly approach the edge of the board.

[0024] As a further implementation, the flying saw 3 includes a first frame 315, a second frame 316, a cutting assembly, a walking drive mechanism, and a tracking assembly. The cutting assembly includes a cutting saw blade 301, which is mounted on a cutting motor 303 via a saw blade clamping assembly 302. The cutting motor 303 is mounted on a guide slider assembly 305 via a cutting motor base 304. The end of the slider assembly 305 is fixed to the first frame 315. The first frame 315 and the second frame 316 are connected by the tracking assembly. A support plate 317 for supporting the sheet metal is embedded in the first frame 315, and the support plate 317 is located below the slider assembly 305. The walking drive mechanism is located on the first frame 315. By combining the independent tracking assembly with the cutting assembly, the entire cutting unit can synchronously track the moving sheet metal for cutting, ensuring the perpendicularity and dimensional accuracy of the cut surface. The support plate 317 embedded in the first frame 315 provides a stable cutting support platform for the sheet material, preventing vibration or sagging during cutting. The slider assembly 305 and the motor base ensure the straightness and stability of the movement of the cutting motor 303 and the saw blade.

[0025] As a further implementation, the cutting and walking drive mechanism includes saw blade walking timing pulleys 306 disposed at both ends of the slider assembly 305, and a saw blade walking timing belt 307 surrounding the saw blade walking timing pulleys 306. The saw blade walking timing belt 307 is fixedly connected to the cutting motor base 304 through a timing belt pressure plate 308. By using a timing belt and timing pulley transmission method, the cutting motor base 304 and the saw blade are driven to move along the slider assembly 305, achieving smoothness, synchronization, and position controllability of the saw blade feed during the cutting process; simultaneously, it can quickly respond to control commands, achieving precise start, stop, and speed control, meeting the process requirements of the flying saw 3.

[0026] As a further implementation, the tracking component includes a tracking motor 314, a tracking timing pulley 310 arranged back and forth along the material travel direction, and a tracking timing belt 311 surrounding the tracking timing pulley 310. The tracking timing belt 311 is connected to a tracking slider assembly 312. The tracking timing belt 311 is fixedly connected to the first frame 315 via a tracking timing belt pressure plate 313. The tracking motor 314 is connected to the tracking timing pulley 310 and provides power to the tracking timing belt 311. By driving the timing belt with the tracking motor 314, the first frame 315 and the carrying cutting assembly move at the same speed as the board material, completing the cutting in a relatively stationary state, thus eliminating cutting errors caused by board material movement.

[0027] As a further implementation, the reversing conveyor 4 includes a reversing frame 403 and a reversing pallet 402. Sliding units 404 are respectively arranged on both sides of the reversing frame 403 in the discharge direction. Pallets are slidably mounted on the sliding units 404 and driven by a reversing cylinder 401. The moving direction of the reversing cylinder 401 is perpendicular to the feeding direction in the horizontal plane, enabling it to receive material from the flying saw 3. A conveying roller conveyor 405 is arranged below the pallet, and the conveying direction of the conveying roller conveyor 405 is perpendicular to the feeding direction in the horizontal plane, thus achieving reversal. After the sliding pallet receives material from the flying saw 3 driven by the reversing cylinder 401, the material is then delivered by the vertically arranged conveying roller conveyor 405 below, cleverly completing a right-angle change in the material's travel direction.

[0028] As a further implementation, the blade 501 in the film-coating and cutting machine 5 is connected to the drive end of the cutting cylinder 503; an upper support plate 505 is provided on the cutting frame 506, which is connected to the cutting frame 506 through an upper support plate frame 507; an upper silicone plate 504 is provided below the upper support plate 505, which is located below the blade 501 and is used to provide cushioning when the blade 501 rises; a material support plate 502 for supporting materials is provided below the upper silicone plate 504; the device also includes an encoder for providing a length signal, which is provided on the side film-coating machine 2 and controlled to the cutting cylinder 503 so that the cutting action of the cutting cylinder 503 corresponds to the gap position between adjacent rock wool boards 6.

[0029] Example 2 This embodiment provides a working method for a rock wool board 6 six-sided film lamination processing equipment, including the following steps: Step 1: The cleaned rock wool board 6 enters the glue spraying and laminating machine 1 and is conveyed to the glue spraying area by the conveying roller 111. The fan-shaped nozzles 113 of the upper glue spraying pipeline system 109 and the lower glue spraying pipeline system 110 spray glue evenly on the upper and lower surfaces of the rock wool board 6. Then, the upper film pressing roller 105 and the lower film pressing roller 106 press the upper film and the lower film onto the upper and lower surfaces of the rock wool board 6 respectively. Step 2: The coated rock wool board 6 enters the first side coating machine 2. The rock wool board 6 is placed on the base plate 210 and pushed forward by the subsequent board. The side film is guided by the side film assembly 202 and is heated by the side film constraint block 205 and the side film heating block assembly 206 in sequence before being attached to one side of the rock wool board 6. It is then pressed by the rear pressure roller 207. At the same time, the length measuring wheel 208 contacts the board and drives the encoder to record the conveying length of the board. Step 3: Rock wool board 6 enters the flying saw 3 station. The flying saw 3 control unit identifies the board gap according to the length data provided by the encoder. When the gap moves to below the cutting saw blade 301, the tracking motor 314 starts, so that the cutting saw blade 301 moves synchronously with the board. At the same time, the walking motor 309 drives the cutting saw blade 301 to move laterally, cutting the upper and lower films and a set of side films on the upper and lower surfaces of the board vertically along the gap. Step 4: The cut rock wool board 6 enters the reversing conveyor 4, the board is pushed onto the pallet, and then the cylinder drives the pallet to be pulled away to both sides, so that the rock wool board 6 falls into the lower conveyor roller 405, and the conveying direction becomes perpendicular to the board feeding direction. Step 5: After reversing, the rock wool board 6 enters the second side film covering machine 2, and the side film is heated and covered on the other side of the rock wool board 6 in the same way as in Step 3; Step 6: Rock wool board 6 enters the film-coating and cutting machine 5. According to the length data provided by the encoder, when the board moves to the cutting position, the cylinder drives the cutter head 501 to rise and cut the side film, thus completing the film application of rock wool board 6.

10. The working method of the processing equipment for applying film to six sides of rock wool board as described in any one of claims 1-9, characterized in that, Includes the following steps: Step 1: After cleaning, the rock wool board enters the glue spraying and laminating machine and is conveyed to the glue spraying area by the conveying roller. The fan-shaped nozzles of the upper and lower glue spraying pipeline system spray glue evenly on the upper and lower surfaces of the rock wool board. Then, the upper and lower films are pressed onto the upper and lower surfaces of the rock wool board by the upper film pressing roller and the lower film pressing roller, respectively. Step 2: The coated rock wool board enters the first side coating machine. The rock wool board is placed on the base plate and pushed forward by the subsequent board. The side film is guided by the side film assembly and is heated by the side film constraint block and the side film heating block assembly in sequence before being attached to one side of the rock wool board. It is then pressed by the rear pressure roller. At the same time, the length measuring wheel contacts the board and drives the encoder to record the conveying length of the board. Step 3: The rock wool board enters the flying saw station. The flying saw control unit identifies the gap of the board according to the length data provided by the encoder. When the gap moves to the bottom of the cutting saw blade, the tracking motor starts, so that the cutting saw blade moves synchronously with the board. At the same time, the travel motor drives the cutting saw blade to move laterally, cutting the upper and lower films and side films on the upper and lower surfaces of the board vertically along the gap. Step 4: The cut rock wool board enters the reversing conveyor. The board is pushed onto the pallet, and then the reversing cylinder drives the reversing pallet to move to both sides, so that the rock wool board falls into the conveying rollers below, and the conveying direction becomes perpendicular to the board feeding direction. Step 5: After reversing, the rock wool board enters the second side laminating machine, and the side film is heated and applied to the other side of the rock wool board using the same method as in Step 3; Step Six: The rock wool board enters the film-coating and cutting machine. Based on the length data provided by the encoder, when the board moves to the cutting position through the gap, the cutting cylinder drives the cutter head to rise and cut the side film, thus completing the film application of the rock wool board.
