The control servo motor 18 is activated; the temperature control module 20 is installed around the automatic moving mechanism 5 of the longitudinal sealing hot knife and the automatic moving mechanism 6 of the transverse sealing hot knife; the temperature control module 8 includes a second CAN interface unit, an MCU controller, a driver chip, a temperature sensor and an IGBT tube; the MCU controller is connected to the CAN branch line via the second CAN interface unit; the MCU controller is connected to the temperature sensor via the temperature acquisition circuit; the MCU controller is connected to the driver chip; the driver chip is connected to the gate of the IGBT tube, the emitter of the IGBT tube is grounded, and the collector of the IGBT tube is connected to the heating wire of the longitudinal heat sealing component and the transverse heat sealing component, and then connected to the CAN bus human-machine interface through the CAN bus, and connected to the power module through the power cord. The temperature control module receives the CAN bus human-machine interface temperature control instructions through the CAN bus, controls the IGBT tube, powers on or off the heating wire, and collects the current radiator temperature through the temperature sensor (thermocouple). After the MCU controller performs PID calculation, the power-on / power-off action is adjusted in a closed loop, thereby controlling the radiator temperature to quickly reach and maintain the temperature required by the human-machine interface instruction.

[0040] The present invention utilizes a CAN bus approach, utilizing the CAN bus and CAN branch lines to connect servo motors, input / output modules, and temperature control modules. This achieves unified signal transmission, eliminating the need for cables connecting different control components to the electrical control box. The CAN bus can also be bundled with power cables, reducing the number of cables required for automated control. Furthermore, this effectively reduces electromagnetic interference between various high-voltage and low-voltage cables in traditional solutions, improving system stability and reliability. Due to the use of a distributed control system, adding or removing control components is very convenient without affecting the existing system hardware and software architecture, greatly facilitating product serialization and upgrades.

The running gear 504 moves along the rack 501, driving the longitudinal heat-sealing assembly 3 to adjust its position. The automatic movement mechanism for the transverse heat-sealing blade also utilizes a gear and rack mechanism. To prevent the longitudinal heat-sealing assembly from deviating from its track, a limit switch is located at the bottom of the motor mount. When the limit switch contacts contact a limit plate, the motor stops, halting the longitudinal heat-sealing assembly.

The second controller monitors the output signal of the driving motor of the controller traction roller 11 in real time, and the second controller drives the tension swing arm 10 to move according to the monitored output signal. When the traction roller 11 pulls the material forward, the second controller controls the swing arm adjustment mechanism 12 to drive the tension swing arm 10 to move upward or downward, thereby reducing the traction tension of the material and avoiding the material in the conveying channel 2 from wrinkling or cracking due to excessive traction force.

The guide assembly 125 includes a fixed block 1231 disposed on the inner side of the frame 1, a polished rod 1232 is disposed on the fixed block 1231, one end of the movable plate 124 is disposed on the polished rod 1232, the movable plate includes a gusset plate connected to the belt and a sliding block disposed on the polished rod, the sliding block and the gusset plate are provided with a base plate, and the tension swing arm is disposed on the base plate.

The first adjusting roller 101 is connected to the first portion 1241, and the second adjusting roller 102 is connected to the second portion 1242. The film material is divided into two layers, the upper and lower layers, so the tension swing arm roller group is provided with two adjusting rollers, corresponding to the two layers of film material respectively. Figure 7 As shown in the figure, it mainly shows the overall workflow of each component. First, the visual probe is used to detect whether the material position is offset. If offset occurs, the image signal is sent to the controller, which controls the operation of the two automatic moving mechanisms, thereby driving the displacement of the two heat sealing components, synchronizing the positions of the heat sealing components and the material, thereby ensuring the heat sealing quality. Figure 8As shown, the visual probe detects whether the material position is offset and compares the material position with the standard image. If there is any inconsistency, the system controls the movement of two automatic moving mechanisms, which in turn drives the movement of the heat sealing component and moves the heat sealing component to a position synchronized with the material to ensure the heat sealing quality.

[0044] The working principle of the present invention is as follows: the image information collected by the visual probe is received by the first controller, and then the longitudinal sealing hot knife automatic moving mechanism and / or the transverse sealing hot knife automatic moving mechanism are triggered to move, the longitudinal sealing hot knife automatic moving mechanism drives the longitudinal heat sealing component to move, and the transverse sealing hot knife automatic moving mechanism drives the transverse heat sealing component to move, and the positions of the longitudinal heat sealing component and the transverse heat sealing component are corrected in real time to ensure the accuracy of the longitudinal and transverse heat sealing of the material, improve the sealing effect, and ensure the quality of the finished product; secondly, the tension of the film material is monitored by the distributed control system, and then corresponding instructions are issued to control the movement of the corresponding drive mechanism to adjust the position of the tension floating roller or the tension swing arm, so as to achieve effective adjustment of the tension of the film material.
