Embodiment
Below will combine Figure of description and specific embodiment that the present invention is done further explain.
As shown in Figure 1; Large-volume infusion soft bag production lines of the present invention covers heating control system with weldering; Comprise Control Component 2 and the heat regulation executive module 3 that links to each other with heating plate 5 with weldering lid, Control Component 2 and is used for detecting and welds the detection components of covering with heating plate 5 heated conditions 4 and link to each other and according to the detection signal of detection components 4 heat regulation executive module 3 is controlled.
In the present embodiment, detection components 4 detects the current detecting unit of weldering lid with heating plate 5 working currents in real time for being used for, and promptly this detection components 4 can be for being installed in the current transformer 41 on heat regulation executive module 3 outlet lines.Current transformer 41 links to each other with an alarm unit (not shown) with a current displaing unit 42.In the present embodiment, adopt digital ammeter to realize the function of current displaing unit 42 and alarm unit.
In the present embodiment; Heat regulation executive module 3 comprises the AC voltage adjusting module 31 and heating transformer 32 that links to each other successively; AC voltage adjusting module 31 links to each other with the output terminal of Control Component 2 and receives control signal, and the output terminal of heating transformer 32 links to each other with heating plate 5 with the weldering lid.Control Component 2 is Programmable Logic Controller 21 (PLC), the analog output module 23 that Programmable Logic Controller 21 is provided with the digital quantity input module 22 that is used for linking to each other with detection components 4 and is used for linking to each other with heat regulation executive module 3.
