所述上料系统1包括采用上料电机8驱动的上料架7，上料架7通过定位转子定位PVC原片，上料架7侧部设有物料有无检测传感器9，上料架7将PVC原片上料至输送链条11后，物料有无检测传感器9检测到PVC原片，物料有无检测传感器9向PLC控制系统10发送信号，PLC控制系统10接收信号后向上料电机8发送指令，上料电机8暂停运行。The feeding system 1 includes a feeding rack 7 driven by a feeding motor 8. The feeding rack 7 positions the PVC original sheet by a positioning rotor. A material presence detection sensor 9 is provided on the side of the feeding rack 7. After the feeding rack 7 feeds the PVC original sheet to the conveying chain 11, the material presence detection sensor 9 detects the PVC original sheet. The material presence detection sensor 9 sends a signal to the PLC control system 10. After receiving the signal, the PLC control system 10 sends an instruction to the feeding motor 8, and the feeding motor 8 stops running.
通过加热装置2对PVC原片进行加热，具体为，PVC原片通过输送链条11输送至加热装置2处，输送链条11通过伺服电机14驱动，所述加热装置2采用上下移动式加热砖对PVC原片进行加热，加热砖为通过PLC控制系统10控制的电加热砖，电加热砖可更换，从而与淋水片长度相匹配，加热装置2入口处设有用于检测淋水片位置的位置检测传感器，当淋水片被输送至与电加热砖上下正对位置时，位置检测传感器向PLC系统发送到位信号，PLC系统控制伺服电机停止运转，加热砖对淋水片进行加热，电加热砖与淋水片长度相同，上下正对进行直接加热，减少热量的损失，提高热利用效率。所述加热装置中设有温度传感器，温度传感器与PLC控制系统10电连接，温度传感器检测到温度达到加热温度上限时，向PLC控制系统10发送信号，PLC控制系统10向电加热砖发送停止指令，电加热砖停止加热，当温度降至加热温度下限时，温度传感器向PLC控制系统10发送信号，PLC控制系统10向电加热砖发送加热指令，电加热砖开始加热。电加热砖可同时或单独加热工作，即可单独对每块加热砖控温，也可分区分片宏观控温。独立控温加热区域温度灵活可调。The PVC original sheet is heated by the heating device 2. Specifically, the PVC original sheet is transported to the heating device 2 through the conveying chain 11. The conveying chain 11 is driven by the servo motor 14. The heating device 2 uses an up and down movable heating brick to heat the PVC original sheet. The heating brick is an electric heating brick controlled by the PLC control system 10. The electric heating brick is replaceable to match the length of the water sprinkling sheet. A position detection sensor for detecting the position of the water sprinkling sheet is provided at the entrance of the heating device 2.

When the temperature drops to the lower limit of the heating temperature, the temperature sensor sends a signal to the PLC control system 10, and the PLC control system 10 sends a heating command to the electric heating brick, and the electric heating brick starts heating. The electric heating bricks can be heated simultaneously or individually, that is, each heating brick can be temperature-controlled individually, or the temperature can be controlled macroscopically in different zones and sections. The temperature of the independently controlled heating area is flexible and adjustable.

The upper and lower molds of the forming mold move relatively to extrude and pre-form the surface of the water-spraying sheet. The hydraulic system is controlled by the PLC control system 10. The hydraulic forming system 3 also includes an in-place sensor for monitoring the forming mold. After the in-place sensor detects that the forming mold moves into place and performs a forming operation, it sends a signal to the PLC control system 10. After receiving the signal, the PLC control system 10 delays for a predetermined period of time and then sends a command to the hydraulic mechanism and the servo motor 14. The hydraulic mechanism opens the mold, and the conveyor chain 11 runs to transport the formed PVC sheet to the vacuum forming machine for vacuum forming.
