The structure of the rockwool sandwich panel machine with double belt press system is relatively complex, and each component cooperates closely to complete the production process of rockwool sandwich panels. Generally speaking, the whole machine is composed of feeding system, double belt press system, heating and curing system, cutting system, conveying system and electrical control system, and each part undertakes different functions to ensure the smooth progress of the production line. The feeding system is the starting link of the production process, which is mainly responsible for transporting the raw materials required for the production of rockwool sandwich panels to the subsequent processing links in an orderly manner. The raw materials involved mainly include rockwool core material, surface protective layer materials (such as metal sheets, composite sheets, etc.) and bonding agents. The feeding system is usually equipped with special feeding devices for different raw materials, such as the unwinding device for metal sheets, the conveying device for rockwool core material, and the gluing device for bonding agents. The unwinding device can stably unfold the coiled metal sheets and adjust the tension to ensure that the surface of the metal sheets is flat and free of wrinkles, which lays a foundation for the subsequent lamination quality. The conveying device for rockwool core material adopts a continuous conveying structure, which can accurately control the feeding speed and thickness of the rockwool core material, ensuring that the core material can be evenly distributed between the two surface layers. The gluing device adopts a precise dosing system, which can evenly coat the bonding agent on the surface of the rockwool core material or the surface protective layer, and the coating amount can be adjusted according to the production requirements to ensure the bonding strength between the layers and avoid problems such as delamination of the finished panels.

The double belt press system is the core component of the entire machine, which directly determines the bonding quality, flatness and structural stability of the rockwool sandwich panels. This system is mainly composed of upper and lower press belts, driving devices, pressure adjustment devices, guiding devices and supporting rollers. The press belts are usually made of high-strength, high-temperature resistant and wear-resistant materials, which can withstand the high pressure and high temperature during the production process and have a long service life. The driving device is composed of a motor, a reducer and a transmission mechanism, which can drive the upper and lower press belts to run synchronously at a constant speed, ensuring that the rockwool sandwich panel blank can be pressed uniformly during the conveying process. The pressure adjustment device adopts a hydraulic control system, which can accurately adjust the pressure between the upper and lower press belts according to the thickness of the finished panels and the performance requirements of the raw materials. The pressure adjustment range is wide, and the pressure can be kept stable during the production process, avoiding the problems of uneven pressure leading to uneven thickness of the panels or insufficient bonding strength. The guiding device is used to ensure that the press belts run along a fixed track, preventing the deviation of the press belts during operation, which affects the production quality. The supporting rollers are evenly distributed under the lower press belt and above the upper press belt, which can support the press belts and ensure that the pressure is evenly applied to the entire surface of the rockwool sandwich panel blank. In addition, some advanced double belt press systems are also equipped with edge pressing devices, which can press the edges of the rockwool sandwich panel blank to prevent the edge of the core material from being exposed or the bonding agent from overflowing, ensuring the integrity and aesthetics of the finished panels.

The heating and curing system is closely connected with the double belt press system, which is mainly responsible for heating the rockwool sandwich panel blank during the pressing process to promote the curing of the bonding agent and enhance the bonding strength between the layers. This system is usually composed of heating elements, temperature control devices and thermal insulation layers. The heating elements are evenly arranged inside the upper and lower press belts or around the pressing area, which can generate uniform heat and transfer it to the rockwool sandwich panel blank through the press belts. The heating method can be electric heating, hot oil heating or steam heating, and different heating methods can be selected according to the actual production conditions and the performance of the bonding agent. The temperature control device adopts an intelligent temperature control system, which can accurately detect the temperature of the pressing area and the surface of the press belts in real time, and adjust the heating power according to the set temperature parameters to ensure that the temperature during the production process is kept within the optimal curing temperature range of the bonding agent. The thermal insulation layer is arranged outside the heating and curing system, which can effectively reduce heat loss, save energy consumption, and avoid the impact of high temperature on the surrounding equipment and operators. The heating and curing system and the double belt press system work together, so that the rockwool sandwich panel blank can be pressed and cured at the same time, which greatly shortens the production cycle and improves the production efficiency.

The cutting system is the terminal link of the production line, which is mainly responsible for cutting the continuous rockwool sandwich panels produced by the double belt press system into finished products of specified lengths according to the user's requirements. The cutting system is usually composed of a cutting device, a length measuring device and a control device. The cutting device adopts high-precision cutting tools, such as circular saw blades, band saws or knife blades, which can make clean and smooth cuts, avoiding the problems of burrs, cracks or uneven cuts on the section of the panels. The length measuring device adopts a non-contact measuring method, which can accurately measure the length of the continuous panels in real time and send the measured data to the control device. The control device can automatically control the cutting device to start cutting when the panels reach the specified length, and the cutting speed is synchronized with the conveying speed of the panels, ensuring that the length of the finished products is accurate and the error is within the allowable range. In addition, the cutting system is also equipped with a waste collection device, which can collect the waste generated during the cutting process in a centralized manner, avoiding environmental pollution and ensuring the cleanliness of the production site.

The conveying system runs through the entire production line, which is mainly responsible for transporting the rockwool sandwich panel blanks and finished products between different processing links. The conveying system is composed of multiple conveying rollers, conveyor belts and driving devices, which can realize the continuous and stable conveying of materials. The conveying speed can be adjusted according to the production speed of the entire line to ensure the coordination between each link. The conveying rollers and conveyor belts are made of wear-resistant and corrosion-resistant materials, which can adapt to the harsh working environment of the production line and have a long service life. The electrical control system is the "brain" of the entire machine, which is mainly responsible for controlling the operation of each component of the production line, realizing automatic control and intelligent adjustment. The electrical control system is composed of a PLC controller, a touch screen, a sensor and an actuator. The PLC controller is the core of the control system, which can process the signals sent by various sensors and issue control commands to the actuators according to the preset program. The touch screen is a human-machine interaction interface, through which operators can set production parameters (such as production speed, pressure, temperature, panel length, etc.), monitor the operation status of the production line in real time, and view the production data and fault information. The sensors are used to detect various parameters during the production process, such as pressure, temperature, speed, length, etc., and send the detected signals to the PLC controller. The actuator receives the control commands from the PLC controller and executes corresponding actions, such as starting and stopping the motor, adjusting the pressure, adjusting the temperature, and controlling the cutting device. The electrical control system has the characteristics of high control precision, stable operation and easy operation, which can greatly reduce the labor intensity of operators and improve the automation level and production efficiency of the production line.
