Description

Technical Field

[0001] This invention relates to a method and system for adjusting the pressure of a roller press based on continuous pressing, belonging to the field of composite board processing. Background Technology

[0002] Continuous pressing production of composite panels is a key process for improving the production capacity and quality of building decoration materials. It uses multiple roller presses to roll and convey the panels in sequence, aiming to achieve efficient and stable panel forming.

[0003] Currently, most composite board pressing adopts a static pressure holding method: the board is fixed and pressed in a single press until the adhesive is completely cured before it can be removed and the next board can be produced. However, this method has obvious limitations: on the one hand, the pressure holding time is long and the production efficiency is low; on the other hand, the traditional pressing process does not have continuity and process parameter self-adaptation capabilities, and it is impossible to adjust the pressing height and conveying speed in real time according to the board thickness and surface material type, so it is difficult to achieve efficient continuous operation while ensuring quality. Summary of the Invention

[0004] This invention provides a method and system for adjusting the pressure of a roller press based on continuous pressing. Its main purpose is to realize the continuous operation of composite board pressing and to adaptively adjust process parameters to meet the production needs of different types of composite boards.

[0005] To achieve the above objectives, the present invention provides a method for regulating the pressure of a roller press based on continuous pressing, comprising: Obtain the thickness information and surface material type of the material to be pressed, and determine the set pressing height and conveying speed of the target roller press based on the thickness information and surface material type; According to the set pressing height, the upper moving main frame on a single roller press in the target roller press unit is adjusted, and the plate to be pressed is pressed down to obtain a flattened plate. After configuring the belt motor unit of a single roller press in the target roller press unit, the automatic mode corresponding to the belt motor unit is configured based on the preset PLC automation control system. In the automatic mode, the target roller press units are controlled to be arranged in sequence to form a continuous pressing production line. The flattened sheet is input through the first roller press in the continuous pressing production line and clamped and pressed by the upper and lower belts of the remaining roller presses to obtain a continuously pressed sheet. After the continuously pressed sheet passes through all the roller presses in sequence, the continuously pressed sheet is shaped and cut according to the preset sheet length to obtain the finished composite sheet.

[0006] Optionally, in the automatic mode, controlling the target roller press units to be arranged sequentially to form a continuous pressing production line includes: Based on the physical layout of each roller press in the target roller press unit, determine the installation sequence of each roller press along the conveying direction; The installation station sequence is bound to the equipment number of each roller press to obtain the roller press sequence table; Based on the roller press sequence table, after establishing start / stop interlock signals between target roller press units in the PLC automated control system, the target roller press units are controlled to interlock sequentially to form a continuous pressing production line.

[0007] Optionally, the start / stop interlock signal represents an electrical control association signal established between each roller press. Each roller press must receive a ready signal from the previous roller press before starting. Only when the ready signal is valid can the next roller press start and run. At the same time, if any roller press stops or malfunctions, its interlock signal will prevent the start of subsequent roller presses and control the already running roller presses to stop in sequence, thereby ensuring that each roller press starts and stops strictly in sequence.

[0008] Optionally, determining the set pressing height and conveying speed of the target roller press based on the thickness information and the surface material type includes: Based on the thickness information, determine the theoretical pressing gap required for each roller press in the target roller press unit; Based on the theoretical pressing gap, the set pressing height of the roller press in the target roller press unit is set; Obtain the reference conveying rate that matches the surface material type in the preset process parameter table, and determine the conveying speed of the target roller press unit by combining the equipment calibration parameters of the target roller press unit.

[0009] Optionally, adjusting the upper moving main frame on a single roller press in the target roller press unit according to the set pressing height includes: According to the set pressing height, after driving the height adjustment motor on the roller press in the target roller press unit, the transmission screw connected to the height adjustment motor is rotated for adjustment to obtain specific adjustment parameters. Based on the specific adjustment parameters, the vertical displacement corresponding to the screw nut seat assembled on the transmission screw is analyzed. Based on the vertical displacement, after connecting the nut seat connecting plate on the lead screw nut seat to the T-shaped slider connecting plate fixed to the upper moving main frame, the slider on the T-shaped slider connecting plate is controlled to slide along the T-shaped slider guide rail, so that the upper moving main frame descends to a position corresponding to the set pressing height.

[0010] Optionally, after pressing the sheet material to be pressed to obtain a flattened sheet material, the process includes: The rolling zone of the material to be pressed is defined in the roller press by the upper belt and the lower belt. After the upper belt and upper roller press the material to be pressed in the rolling area, a flattened material with a flatness that meets the preset standard is obtained.

[0011] Optionally, the preset PLC automation control system configures the automatic mode corresponding to the belt motor group, including: The control start command is generated in the preset PLC automation control system; The operating speed parameters preset for the belt motor group in the PLC automation control system are invoked. The operating speed parameter is sent to the driver of the belt motor group through the output port of the PLC automation control system; Based on the driver and the control start command, the belt motor group is configured to enter a continuously controlled automatic mode.

[0012] Optionally, the step of feeding the flattened sheet material into the first roller press in the continuous pressing production line, and clamping and pressing it via the upper and lower belts of the remaining roller presses to obtain a continuously pressed sheet material includes: Start the upper and lower belts of the first roller press so that the flattened plate forms an initial pressing section under the roller press; After the initial pressing section enters the pressing area of ​​the adjacent roller press, the initial pressing section is overlapped and pressed, and each subsequent roller press synchronously starts its upper and lower belts when the initial pressing section arrives, ensuring that the initial pressing section is always under the clamping and pressing action of at least one roller press throughout the entire conveying path. After the tail of the sheet material detaches from the penultimate roller press and fully enters the last roller press to complete the final pressing, the continuously pressed sheet material is output.

[0013] Optionally, the step of shaping and cutting the continuously pressed sheet based on a preset sheet length to obtain a finished composite sheet includes: Based on the preset plate length, the position of the front end of the plate output from the last roller press is detected. When the front end of the plate reaches the cutting entrance of the preset cutting machine, the cutting stroke corresponding to the continuous pressing plate is determined. When the cutting stroke reaches its end point, the continuously pressed sheet is formed and cut to obtain the finished composite sheet.

[0014] To address the aforementioned problems, the present invention also provides a pressure regulating system for a roller press based on continuous pressing, the system comprising: The sheet material setting module is used to obtain the thickness information and surface material type of the sheet material to be pressed, and to determine the set pressing height and conveying speed of the target roller press based on the thickness information and surface material type. The pressing module is used to adjust the upper moving main frame on a single roller press in the target roller press unit according to the set pressing height, and to press the plate to be pressed to obtain a flattened plate. The mode configuration module is used to configure the belt motor group of a single roller press in the target roller press group, and then configure the automatic mode corresponding to the belt motor group based on the preset PLC automation control system. The continuous pressing module is used in the automatic mode to control the target roller press units to be arranged in sequence to form a continuous pressing production line. The flattened sheet material is input through the first roller press in the continuous pressing production line and clamped and pressed by the upper and lower belts of the remaining roller presses to obtain a continuously pressed sheet material. The forming and cutting module is used to form and cut the continuously pressed sheet material according to a preset sheet length after the continuously pressed sheet material has passed through all the roller presses in sequence, so as to obtain the finished composite sheet material.

[0015] Compared to the problems described in the background art, the embodiments of the present invention can accurately capture the core characteristics of the sheet material, providing a reliable basis for setting the pressing process parameters, and achieving precise adaptation between the process parameters and the sheet material characteristics. This ensures the stability and controllability of the pressing process and effectively avoids molding problems caused by parameter mismatch. Furthermore, the embodiments of the present invention allow the pressing action to precisely match the pressing requirements of the sheet material, ensuring a tight fit between the layers of the sheet material and preventing gaps or misalignment between layers. This lays a stable foundation for subsequent continuous pressing of the sheet material and ensures a regular structure of the formed sheet material. Finally, the embodiments of the present invention allow the power output of the upper and lower belts to remain coordinated, providing a stable power foundation for sheet material conveying and pressing, while also enabling belt motor operation. Precise control of the group's operating parameters ensures stable operation of the roller press, guaranteeing smooth and orderly pressing and conveying. Furthermore, this embodiment of the invention, by inputting the flattened sheet material from the first roller press and clamping it with the upper and lower belts of the remaining roller presses, allows the sheet material to receive uniform and continuous pressure throughout the process. This results in stronger adhesion between the layers of the sheet material, ensuring the overall forming quality of the continuously pressed sheet material. Moreover, this embodiment of the invention performs forming and cutting according to a preset sheet material length, ensuring that the dimensions of the finished composite sheet material precisely match application requirements. This avoids waste or non-compliance due to improper dimensional control after pressing, guaranteeing the dimensional uniformity of the finished sheet material. Therefore, this invention achieves continuous operation of composite sheet material pressing, with adaptively adjustable process parameters to meet the production needs of different types of composite sheets.

[0021] The term "board to be pressed" refers to a pre-formed board blank formed by initially bonding structural materials, fiberglass, aluminum honeycomb core, and decorative surface materials with polyurethane foam, before continuous pressing by a roller press. It possesses a basic layered structure but has not yet undergone final pressing and curing. The "thickness information" refers to the pre-designed or measured thickness of the board before pressing, a core parameter characterizing its thickness. Its value ranges from 18mm to 50mm, directly reflecting the required spatial dimensions for pressing. The "surface material type" refers to the material category of the outer decorative surface material of the board, i.e., the material properties used for decoration or functional enhancement on the surface of the composite board, including ceramic tiles, stone, slabs, ceramic tiles, wood veneer, etc. Specific material types include glass and metal; the target roller press unit refers to a combination of multiple roller presses arranged in a preset order, specifically used for continuous pressing of specific sheet materials, including roller presses #1 to #9, forming a continuous pressing unit; the set pressing height refers to the target distance parameter between the upper movable main frame and the lower fixed main frame of the roller press, determined based on the thickness information and surface material type of the sheet material to be pressed, used to adapt the spatial size setting to the pressing requirements of the sheet material; the conveying speed refers to the rate at which the upper and lower belts of the roller press drive the sheet material to be pressed forward during the pressing process, determined by matching the sheet material thickness and surface material type, and is a key operating parameter for controlling the pressing time of the sheet material in the roller press.

[0022] Optionally, the thickness information and surface material type of the sheet to be pressed can be obtained by retrieving preset thickness information and surface material type identifiers of the sheet to be pressed through a touch input terminal associated with the production order system; then, a laser thickness sensor is deployed at the feed end of the roller press to detect the distance between the upper and lower surfaces of the sheet by emitting a laser beam, obtain the actual thickness and verify it with the preset value; at the same time, a visual recognition component is used to photograph the surface of the sheet, extract features such as texture and color, and compare them with the preset surface material feature library to confirm the type; finally, the verified thickness data and matching results are summarized to achieve accurate acquisition of the thickness information and surface material type of the sheet to be pressed.

[0023] As an embodiment of the present invention, determining the set pressing height and conveying speed of the target roller press group based on the thickness information and the surface material type includes: determining the theoretical pressing gap required for each roller press in the target roller press group according to the thickness information; setting the set pressing height corresponding to the roller press in the target roller press group based on the theoretical pressing gap; obtaining the reference conveying rate that matches the surface material type in a preset process parameter table, and determining the conveying speed of the target roller press group in combination with the equipment calibration parameters of the target roller press group.

[0024] The theoretical pressing gap refers to the theoretical distance that needs to be reserved between the upper and lower main frames of each roller press in the target roller press unit, based on the actual thickness information of the board to be pressed, combined with the distribution requirements of the interlayer adhesive and the small deformation allowance during the pressing process, after eliminating invalid gaps. The preset process parameter table refers to a table that is structured and stored in advance through experiments and practice, containing various basic process data related to pressing for different surface material types, such as ceramic tiles, stone, and slabs. The data is categorized and indexed by surface material type, and can be directly matched and queried for key parameters such as the reference conveying rate of the corresponding surface material. The reference conveying rate refers to the standard conveying rate value that uniquely matches the surface material type of the board to be pressed in the preset process parameter table. This value is the basic rate parameter that adapts to the pressing process requirements of the surface material type under standard equipment conditions and conventional pressing environment. The equipment calibration parameters refer to the equipment's own characteristic parameters obtained through professional calibration tests before the target roller press unit is put into formal operation or during periodic maintenance. These parameters include roller speed error, belt drive efficiency, and mechanical clearance compensation value, and are used to correct the reference parameters to adapt to the actual operating state of the equipment.

[0025] S2. According to the set pressing height, adjust the upper moving main frame on the single roller press in the target roller press unit, and press down the plate to be pressed to obtain a flattened plate.

[0026] The embodiments of the present invention enable the pressing action to precisely match the pressing requirements of the board, which can make the structure of each layer of the board fit tightly and avoid gaps or misalignment between layers, thereby laying a stable foundation for the subsequent continuous pressing of the board and ensuring the regularity of the structure of the formed board.

[0027] The upper moving main frame refers to the movable load-bearing structure on the upper layer of the roller press, which is connected to the upper support frame, the screw drive assembly, and the T-shaped slider assembly. It is driven by a height adjustment motor and can move up and down along a preset guide rail. Its position adjustment is directly related to the size of the pressing gap and is the core execution component for realizing the pressing of the sheet material. The flattened sheet material refers to the intermediate sheet material formed after the sheet material to be pressed is pressed down by the upper moving main frame of a single roller press in the target roller press unit at a set pressing height. Its interlayer structure has been initially bonded, the thickness meets the preset standard, and the surface material properties and basic structure of the original sheet material are preserved.

[0028] As an embodiment of the present invention, adjusting the upper moving main frame on a single roller press in the target roller press group according to the set pressing height includes: driving a height adjustment motor on the roller press in the target roller press group according to the set pressing height, and then driving the transmission screw connected to the height adjustment motor to rotate and adjust to obtain specific adjustment parameters; based on the specific adjustment parameters, analyzing the vertical displacement corresponding to the screw nut seat mounted on the transmission screw; and connecting the nut seat connecting plate on the screw nut seat to the T-shaped slider connecting plate fixed to the upper moving main frame according to the vertical displacement, and then controlling the slider on the T-shaped slider connecting plate to slide along the T-shaped slider guide rail, so that the upper moving main frame descends to a position corresponding to the set pressing height.

[0029] The height adjustment motor refers to the power output component in the roller press used to drive the upper moving main frame to rise and fall. It is connected to one end of the transmission screw and can receive control signals corresponding to the set pressing height. It drives the transmission screw to rotate by outputting torque. Its structure is adapted to the power transmission requirements of the roller press and is the core power source for realizing the position adjustment of the upper moving main frame. The transmission screw refers to the core component of the roller press screw transmission assembly. It is threaded rod shaped, with one end connected to the height adjustment motor and the other end equipped with a screw nut seat. It transmits power through threaded engagement and can convert the rotational motion of the height adjustment motor into linear motion. It is a key transmission component connecting the power output and the displacement of the upper moving main frame. The specific adjustment parameters refer to the quantitative data generated by the transmission screw during the rotation adjustment process after driving the height adjustment motor based on the set pressing height, including rotation angle, speed, and rotation time. The screw nut seat is an adapter component mounted on the transmission screw, with internal threads that match the transmission screw. The internal thread structure allows the lead screw to move axially along the lead screw as it rotates. It is externally fixed to the nut seat connecting plate and is a key conversion component that transforms the rotational motion of the lead screw into linear displacement. The vertical displacement refers to the distance the lead screw nut seat moves vertically along the lead screw axis, determined based on the specific adjustment parameters of the lead screw. Its value directly corresponds to the required lifting stroke of the upper moving main frame. The T-shaped slider connecting plate is a plate-shaped connecting component with one end fixed to the nut seat connecting plate on the lead screw nut seat and the other end fixed to the upper moving main frame. It is fitted with T-shaped sliders and can transmit the vertical displacement force of the lead screw nut seat, allowing the upper moving main frame to move synchronously with the sliders. The T-shaped slider guide rail is a guide component fixed to the upper support frame or related structure of the lower fixed main frame of the roller press. It is T-shaped and adapts to the T-shaped sliders on the T-shaped slider connecting plate, providing stable guidance and limiting for the vertical sliding of the sliders, ensuring the upper moving main frame rises and falls smoothly along a preset trajectory.

[0030] Furthermore, as another embodiment of the present invention, the step of pressing the material to be pressed to obtain a flattened material includes: determining the rolling area of ​​the material to be pressed in the roller press formed by the upper belt and the lower belt; and pressing the material to be pressed in the rolling area by the upper belt and the upper roller to obtain a flattened material that meets the preset standard flatness.

[0031] The upper and lower belts refer to the rubber transmission belts respectively mounted on the upper movable main frame and the lower fixed main frame in the roller press. The upper belt is connected to the upper belt motor, the upper roller, and the upper belt tensioning roller, while the lower belt is connected to the lower belt motor, the lower roller, and the lower belt tensioning roller. The two are arranged opposite to each other and are used to clamp the sheet material to be pressed and transmit the pressing force and conveying power. The roller pressing area refers to the closed space area formed between the upper and lower belts in the roller press. Its range is adapted to the effective pressing length of the roller press. After the sheet material to be pressed enters this area, it will be subjected to the combined action of the upper and lower belts and the corresponding rollers. It is the core working space for achieving the flatness of the sheet material under pressure. The preset standard flatness refers to the quantitative index of the flatness of the sheet material surface set in advance based on the application scenario and production process requirements of the composite sheet material. Specifically, it is manifested as the unevenness deviation between any two points on the sheet material surface not exceeding the preset threshold. This index needs to be clearly defined in combination with factors such as the surface material type and the sheet material thickness. It is the key basis for judging whether the sheet material meets the pressing requirements.

[0032] S3. After configuring the belt motor unit of a single roller press in the target roller press unit, configure the automatic mode corresponding to the belt motor unit based on the preset PLC automation control system.

[0033] The embodiments of the present invention enable the power output of the upper and lower belts to remain coordinated, providing a stable power foundation for the conveying and pressing of the sheet metal. At the same time, it enables precise control of the operating parameters of the belt motor group, allowing the roller press to maintain a stable operating state, thereby ensuring the smooth and orderly operation of pressing and conveying.

[0034] The belt motor unit refers to the set of power components in the roller press used to drive the belt, including an upper belt drive motor and a lower belt drive motor, which are respectively connected to the upper pulley, the lower pulley, the reducer, and the transmission belt.

The preset PLC automatic control system refers to the programmable logic control unit pre-configured to realize the continuous pressing of composite materials. It is linked with the roller press's motor unit, sensors, and touch screen control terminal. It can receive signals such as material process parameters and equipment operating status, and output control commands through preset programs to coordinate the actions and operating parameters of multiple roller presses. It is the core control module for the intelligent operation of the system. The automatic mode refers to the roller press operation mode based on the preset program of the PLC automatic control system. After startup, no real-time manual intervention is required. The system can automatically coordinate the orderly operation of components such as the belt motor unit and the height adjustment mechanism according to the preset pressing height, conveying speed, and other parameters, so that the roller press completes the pressing and conveying of the material according to the predetermined process. It is the key operating state to achieve continuous operation.

[0035] Optionally, the configuration of the belt motor unit of a single roller press in the target roller press group can be achieved by selecting the upper and lower belt drive motors of the target roller press through the touch operation terminal of the roller press, and entering the preset speed and torque parameters that match the sheet metal process; then starting the motor for no-load test run, and collecting real-time operating data through the speed sensor of the motor; finally comparing the preset parameters with the actual data, fine-tuning the output of the motor drive module to ensure coordinated operation of the upper and lower motors, and ultimately achieving precise configuration of the belt motor unit corresponding to the target roller press.

[0036] As an embodiment of the present invention, configuring the automatic mode corresponding to the belt motor group based on the preset PLC automation control system includes: generating a control start command in the preset PLC automation control system; calling the running speed parameters preset for the belt motor group in the PLC automation control system; sending the running speed parameters to the driver of the belt motor group through the output port of the PLC automation control system; and configuring the belt motor group to enter a continuously controlled automatic mode according to the driver and the control start command.

[0037] The control start command refers to a signal generated and sent by a pre-set PLC automated control system based on the pressing process requirements. It triggers the switching of the belt motor group, height adjustment motor, and other actuators in the roller press from standby to operating state. This signal includes key information such as the action trigger sequence and actuator identification, and is the core trigger signal for starting the operation of related components. The operating speed parameter refers to quantitative data pre-set and stored in the control system based on the thickness of the sheet material to be pressed, the surface material type, and the pressing process standards. It covers key indicators such as belt conveyor speed and motor speed, directly regulating the operating speed of the belt motor group, conveyor rollers, and other moving parts in the roller press. The basic parameters ensure that the components operate according to the preset rhythm; the output port refers to the physical or logical interface in the PLC automation control system used to transmit signals and data to the outside. It establishes a signal connection with the actuators such as the driver and motor of the roller press, and can accurately transmit information such as control start commands and running speed parameters to the target components; the driver refers to the drive device that is matched with the power components such as the belt motor and height adjustment motor of the roller press. One end receives the control commands and speed parameters of the control system through the output port, converts the electrical signal into a power signal adapted to the motor operation, and provides stable drive power to the motor. It is an intermediate conversion component that connects the control signal and the actual action of the motor.

[0038] S4. In the automatic mode, the target roller press units are arranged sequentially to form a continuous pressing production line. The flattened sheet is input through the first roller press in the continuous pressing production line and clamped and pressed by the upper and lower belts of the remaining roller presses to obtain a continuously pressed sheet.

[0039] In this embodiment of the invention, the flattened sheet material is input from the first roller press and then clamped and pressed by the upper and lower belts of the remaining roller presses. This allows the sheet material to receive uniform and continuous pressure throughout the process, making the bonding of each layer of the sheet material more stable and ensuring the overall forming quality of the continuously pressed sheet material.

[0040] The continuous pressing production line refers to an integrated operation line formed by multiple roller presses in the target roller press unit, such as No. 1 to No. 9, arranged in a preset order. It is linked with the control module, and the pressing height and conveying speed parameters of each roller press are matched to form an uninterrupted pressing channel, which is specifically used for the flattened sheet material to pass through in sequence to complete the continuous pressing operation. The continuously pressed sheet material refers to the intermediate sheet material formed after the flattened sheet material is input from the first roller press of the continuous pressing production line, and is clamped by the upper and lower belts of all subsequent roller presses and subjected to continuous pressure. Its interlayer structure is further bonded, and the original surface material properties and basic specifications are retained.

[0041] As an embodiment of the present invention, the step of controlling the target roller press units to sequentially arrange to form a continuous pressing production line in the automatic mode includes: determining the installation station sequence of each roller press along the conveying direction according to the physical layout of each roller press in the target roller press unit; binding the installation station sequence with the equipment number of each roller press to obtain a roller press sequence table; and, based on the roller press sequence table, after establishing start-stop interlock signals between the target roller press units in the PLC automatic control system, controlling the target roller press units to sequentially interlock to form a continuous pressing production line.

[0042] The physical layout refers to the actual placement and spatial distribution of each roller press in the target roller press unit within the production site, including the spacing between each roller press, its relative position to the infeed and discharge ends, and its orientation along the preset conveying direction. The installation station sequence refers to the order in which each roller press is arranged in the continuous pressing production line, determined based on the sheet material conveying direction and the physical layout of each roller press; that is, the sequence of roller press stations the sheet material passes through from infeed to discharge. The equipment number refers to a unique identifier pre-assigned to distinguish different roller presses in the target roller press unit, such as 1#, 2#, etc. …9#, each number corresponds to an independent roller press, used for precise identification and control of a single device in the control system; the roller press sequence table refers to a structured list formed by binding the installation position sequence of each roller press with its corresponding device number, clearly recording the sequential operation order of the roller presses in the continuous pressing production line; the start / stop interlock signal refers to the control signal set in the PLC automated control system to associate the start / stop status of each device in the target roller press group, which enables the next roller press to start only after the previous roller press has started, and the subsequent devices to stop synchronously when the previous one stops, ensuring that each roller press operates in sequence in a coordinated manner.

[0043] Furthermore, as another embodiment of the present invention, the start-stop interlock signal represents an electrical control association signal established between each roller press. Each roller press must receive a ready signal from the previous roller press before starting. Only when the ready signal is valid can the next roller press start running. At the same time, if any roller press stops or malfunctions, its interlock signal will prevent the start of subsequent roller presses and control the already running roller presses to stop in sequence, thereby ensuring that each roller press starts and stops strictly in sequence.

[0044] Furthermore, as another embodiment of the present invention, the step of inputting the flattened sheet material through the first roller press in the continuous pressing production line and clamping and pressing it through the upper and lower belts of the remaining roller presses to obtain a continuously pressed sheet material includes: starting the upper and lower belts of the first roller press to form an initial pressing section under the roller press; after the initial pressing section enters the pressing area of ​​the adjacent roller press, overlapping and pressing the initial pressing section, and sequentially starting the upper and lower belts of each subsequent roller press when the initial pressing section arrives, ensuring that the initial pressing section is always under the clamping and pressing action of at least one roller press throughout the entire conveying path; and outputting the continuously pressed sheet material after the tail of the sheet material leaves the penultimate roller press and completely enters the last roller press to complete the final pressing.

[0045] The initial pressing section refers to the first section of the flattened sheet material that has undergone preliminary pressing after entering the first roller press of the continuous pressing production line, under the action of the upper and lower belts of the roller press starting and applying clamping pressure. It retains the basic structure of the flattened sheet material. The pressing area refers to the specific space range defined between the upper and lower belts in each roller press. This range matches the effective pressing length of the roller press and has stable clamping pressure conditions. It is the core working area where the sheet material receives clamping and pressing action after entering a single roller press. The conveying path refers to the complete movement trajectory of the sheet material in the continuous pressing production line, from the input port of the first roller press, through the pressing areas of each roller press and the connecting sections between roller presses, to the output port of the last roller press. Its path direction is consistent with the sheet material conveying direction, ensuring that the sheet material continuously passes through all roller presses.

[0046] S5. After the continuously pressed sheet material passes through all the roller presses in sequence, the continuously pressed sheet material is shaped and cut according to the preset sheet material length to obtain the finished composite sheet material.

[0047] The present invention provides a method for forming and cutting the composite board according to a preset board length, which can ensure that the size of the finished composite board accurately matches the application requirements, avoid waste or non-compliance of the board due to improper size control after pressing, and ensure the size uniformity of the finished board with regular specifications.

[0048] The preset board length refers to the quantitative value of the finished product length set in the control system in advance, which is based on the actual application scenario of the composite board, customer order requirements and production process standards. Its value ranges from 1000mm to 3500mm and is the core dimension basis for the forming and cutting of the board after continuous pressing. The finished composite board refers to the final product that is formed by cutting the continuously pressed board according to the preset board length after it has been fully pressed by all the roller presses in sequence. The interlayer structure is completely bonded and cured by polyurethane foam. It has preset thickness, surface material properties and size specifications and can be directly used in architectural decoration and other scenarios.

[0049] As an embodiment of the present invention, the step of forming and cutting the continuously pressed sheet based on a preset sheet length to obtain a finished composite sheet includes: detecting the position of the front end of the sheet output from the last roller press relative to the continuously pressed sheet according to the preset sheet length; determining the cutting stroke corresponding to the continuously pressed sheet when the front end of the sheet reaches the cutting inlet of a preset cutting machine; and performing forming and cutting on the continuously pressed sheet when the cutting stroke ends to obtain the finished composite sheet.

[0050] The "front end position of the sheet material" refers to the real-time spatial position of the end of the continuously pressed sheet material that first leaves the conveying area of ​​the roller press during the output process from the last roller press. This position is the core reference for detecting the cutting timing and is directly related to the start determination of the cutting stroke. Its detection is based on the sheet material conveying direction to determine the initial orientation of the sheet material entering the cutting stage. The "pre-set cutting machine" refers to a dedicated cutting device pre-assembled at the discharge end of the last roller press in the continuous pressing production line. It is aligned with the production line conveying path and is suitable for composite sheets with lengths of 1000mm-3500mm, widths of 600mm-1200mm, and thicknesses of 18mm-50mm. It is specifically designed for receiving... The machine receives the cutting command and performs a precise cutting operation on the continuously pressed sheet material. The cutting inlet refers to the channel opening on the pre-set cutting machine that allows the continuously pressed sheet material to enter the cutting work area. Its position is closely connected to the discharge end of the last roller press. The width and height of the channel are adapted to the maximum size of the sheet material, which can ensure that the sheet material enters the effective cutting range of the cutting machine smoothly and without deviation. The cutting stroke refers to a specific distance calculated based on the preset sheet material length. The starting point is the moment when the front end of the continuously pressed sheet material reaches the cutting inlet, and the ending point is when the sheet material moves along the conveying direction to the spatial position corresponding to the preset length. This stroke is the key threshold for triggering the pre-set cutting machine to start the cutting action.

[0051] Compared to the problems described in the background art, the embodiments of the present invention can accurately capture the core characteristics of the sheet material, providing a reliable basis for setting the pressing process parameters, and achieving precise adaptation between the process parameters and the sheet material characteristics. This ensures the stability and controllability of the pressing process and effectively avoids molding problems caused by parameter mismatch. Furthermore, the embodiments of the present invention allow the pressing action to precisely match the pressing requirements of the sheet material, ensuring a tight fit between the layers of the sheet material and preventing gaps or misalignment between layers. This lays a stable foundation for subsequent continuous pressing of the sheet material and ensures a regular structure of the formed sheet material. Finally, the embodiments of the present invention allow the power output of the upper and lower belts to remain coordinated, providing a stable power foundation for sheet material conveying and pressing, while also enabling belt motor operation. Precise control of the group's operating parameters ensures stable operation of the roller press, guaranteeing smooth and orderly pressing and conveying. Furthermore, this embodiment of the invention, by inputting the flattened sheet material from the first roller press and clamping it with the upper and lower belts of the remaining roller presses, allows the sheet material to receive uniform and continuous pressure throughout the process. This results in stronger adhesion between the layers of the sheet material, ensuring the overall forming quality of the continuously pressed sheet material. Moreover, this embodiment of the invention performs forming and cutting according to a preset sheet material length, ensuring that the dimensions of the finished composite sheet material precisely match application requirements. This avoids waste or non-compliance due to improper dimensional control after pressing, guaranteeing the dimensional uniformity of the finished sheet material. Therefore, this invention achieves continuous operation of composite sheet material pressing, with adaptively adjustable process parameters to meet the production needs of different types of composite sheets.
