[0026] Automated Control System 4 Detailed Implementation

[0027] The following description of the embodiments is with reference to the accompanying drawings, which illustrate specific embodiments in which the present invention can be implemented.

[0028] like Figure 1 As shown, this embodiment discloses a high-efficiency PUR laminating machine, which includes a tension control system 1, an adhesive application system 2, a heating and pressurizing system 3, and an automatic control system 4. The tension control system 1 includes an unwinding device 11, a winding device 12, and multiple tension detection components 13. The adhesive application system 2 is located between the unwinding device 11 and the heating and pressurizing system 3. The unwinding device 11 is used to release material to the adhesive application system 2 so that the adhesive application system 2 can evenly apply adhesive and then convey it to the heating and pressurizing system 3. The heating and pressurizing system 3 is used to heat and pressurize multiple materials to laminate them together. The winding device 12 is located in the next process after the heating and pressurizing system 3, and the winding device 12 is used to wind up the laminated materials. Multiple tension detection components 13 are respectively set on the unwinding device 11 and the winding device 12 and monitor the tension of the materials in real time. The input end of the automatic control system 4 is electrically connected to the multiple tension detection components 13, and the output end of the automatic control system 4 is electrically connected to the unwinding device 11 and the winding device 12 and is used to control the rotation speed of the unwinding device 11 and the winding device 12.

[0029] Before using the high-efficiency PUR laminating machine, materials need to be prepared. According to the lamination process requirements, the materials to be laminated are prepared and installed on the unwinding device 11. When the high-efficiency PUR laminating machine is started, the unwinding device 11 releases the material, which flows into the gluing system 2. After being evenly coated by the gluing system 2, the material enters the heating and pressurizing system 3 in the lamination area. Under the action of the heating and pressurizing system 3, the two materials are laminated together, and finally, the winding device 12 rewinds them. Tension detection components 13 are installed on both the unwinding device 11 and the winding device 12. These components monitor the tension of the material on the unwinding and winding devices 11 and 12 in real time. When the tension changes, the automatic control system 4 automatically adjusts the speed of the motors on the unwinding and winding devices 11 and 12, thereby adjusting the unwinding and rewinding speeds to maintain stable material tension. The tension control system 1 can monitor and adjust the material tension in real time, effectively avoiding material wrinkling and stretching deformation problems, and improving the yield rate. The automatic control system 4 reduces manual operation, lowers labor intensity and production costs, and simultaneously improves production efficiency and product quality consistency. The heating and pressurizing system 3 can adapt to different materials and process requirements, expanding the application range of the high-efficiency PUR laminating machine. Among them, the tension detection component 13 can be a tension sensor.

[0030] The adhesive application system 2 includes an adhesive tank, an adhesive roller, and a spreading device. The adhesive tank stores the adhesive, and the adhesive roller is rotatably mounted inside the adhesive tank to transfer the adhesive from the tank to the surface of the material to be laminated. The spreading device is movable and the gap between it and the adhesive roller can be adjusted. By adjusting the gap between the spreading device and the adhesive roller, the amount of adhesive applied can be precisely controlled, ensuring uniform application. Specifically, the adhesive tank stores PUR adhesive, and the adhesive roller transfers the adhesive from the tank to the surface of the composite material.

[0031] In this embodiment, the automated control system 4 is electrically connected to the coating device and is used to drive the squeegee on the coating device to move, thereby adjusting the gap between the squeegee and the glue roller. By automatically controlling the movement of the squeegee to adjust the gap between the squeegee and the glue roller through the automated control system 4, the amount of glue applied can be precisely controlled, ensuring uniform glue application. At the same time, it reduces manual operation, lowers labor intensity and production costs, and improves production efficiency and product quality consistency.

[0032] The heating and pressurizing system 3 includes a heating roller and a pressure roller, both located between the adhesive application system 2 and the winding device 12, and are used to heat and pressurize the material, respectively. The heating roller heats the PUR adhesive on the material, activating it and enhancing its bonding properties. The pressure roller applies appropriate pressure to the material, ensuring close adhesion between the two materials. Under the action of the heating and pressure rollers, the two materials are bonded together, and finally, the winding device 12 winds them up.

[0033] The automated control system 4 is electrically connected to the heating roller and is used to control the heating temperature of the heating roller. The automated control system 4 is also electrically connected to the pressure roller and is used to control the pressure applied by the pressure roller to the material. Both the temperature of the heating roller and the pressure of the pressure roller can be adjusted by the automated control system 4 to adapt to different material and process requirements.

[0034] In this embodiment, the automated control system 4 is a PLC. The automated control system 4 uses a PLC control system to achieve automated control of various components of the high-efficiency PUR laminating machine. Operators can set various parameters through the human-machine interface, such as adhesive application amount, laminating speed, and tension. The PLC automatically controls the actions of various actuators such as motors and cylinders according to the set parameters, improving production efficiency and product quality stability.

[0035] In this embodiment, during the installation and commissioning of the high-efficiency PUR laminating machine, the various components of the high-efficiency PUR laminating machine are first assembled according to the design requirements, and the electrical wiring and pipes are connected. During commissioning, first check whether the operation of each component is normal, and then set the initial parameters, such as adhesive application amount, lamination speed, tension, etc., through the human-machine interface.

[0036] During the lamination process, the high-efficiency PUR laminating machine is started, and the unwinding device 11 releases the material. After being evenly coated with adhesive by the gluing system 2, the material enters the lamination area. Under the action of the heating roller and the pressure roller, the two materials are laminated together, and finally, the winding device 12 rewinds them. During the lamination process, the tension control system 1 monitors the material tension in real time and automatically adjusts the unwinding and rewinding speeds to ensure the stability of the lamination process.

[0037] During quality inspection, high-efficiency PUR laminating machines regularly test the laminated products to check whether indicators such as bonding strength and appearance meet the requirements. If problems are found, the equipment parameters are adjusted or the equipment's operating status is checked in a timely manner.

[0038] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
