The high cyclic-wave generator has the advantages that: by utilizing the monitoring of the PLC controller, an electric motor is controlled to push the movable capacitor plate to move to the set position, so as to realize automatic adjusting of the high cyclic-wave output intensity, reduce operation steps of workers, and increase the production efficiency.
Description
Technical field:
The utility model relates to a kind of high frequency generator.
Background technology:
When utilizing the high frequency heat sealing machine that plastic products are carried out welding, required intensity high-frequency is determined by the size of welding area, when running into twice of product needed or repeatedly welding different area, carry out welding with regard to the high frequency that needs varying strength, medical infusion bags for example, it needs first welding plastic pipeline and film during production, around back welding two plastic sheetings, and preceding step welding area is different with back step welding area, so the required high frequency intensity in front and back is inequality, this regulates the intensity of high frequency output with regard to requiring, the adjusting of prior art high frequency output intensity is by movable capacitor board on the adjusting generator and the distance between the fixed capacity plate, change the capacitance of two capacitor boards, and then change output intensity size high-frequency, and the mode of regulating is to utilize the manual turn of workman to regulate button, makes movable capacitor board move to the position of setting, automaticity is low, greatly influences production efficiency.
Summary of the invention:
The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, a kind of high frequency generator that can regulate output intensity automatically to be provided.
For achieving the above object, the technical scheme that the utility model provides is: a kind of high frequency generator that can regulate output intensity automatically, include mounting, generator main body, fixed capacity plate and movable capacitor board, mounting is provided with drive motors, this drive motors is connected with movable capacitor board, and movable capacitor board is connected with the PLC controller by circuit.
The main shaft of described drive motors is connected with screw rod, and this screw rod is connected with movable capacitor board.

The specific embodiment:
Now elaborate the utility model in conjunction with the accompanying drawings:
The high frequency heat sealing machine of present embodiment is to be used to produce medical infusion bags, the plastic conduit of this infusion bag during with the plastic sheeting welding the welding area and two plastic sheetings around welding area during welding different, two kinds of high frequencies that intensity is different before and after this will seek survival and need when producing, the high frequency that intensity is little is used for welding plastic pipeline and plastic sheeting, the high frequency that intensity is big is used for around welding two plastic sheetings, this high frequency generator includes mounting 1, generator main body 2, movable capacitor board 3 and fixed capacity plate 4, mounting 1 is provided with drive motors 5, this drive motors 5 is positioned at the below of generator main body 2, the main shaft of drive motors 5 is equipped with screw rod 6, cross-under has along the slide block 7 that can move back and forth along screw rod 6 on screw rod 6, this slide block 7 is fixedlyed connected with movable capacitor board 3, movable plate 8 is installed on slide block 7, the motion path of movable plate 8 is provided with travel switch 9, and movable plate 8 places between the two switch plectrums 10 of travel switch 9, if break down, movable plate 8 is run into switch plectrum 10, travel switch 9 will be at once drive motors 5 outages, prevent to damage drive motors 5 or destroy other part, movable capacitor board 3 is connected by circuit and PLC controller, movable capacitor board 3 whenever moves to a position, movable capacitor board 3 can produce corresponding capacitance with fixed capacity plate 4, movable capacitor board 3 is near more with fixed capacity plate 4 distances, capacitance is big more, the high frequency that passes through is strong more, otherwise distance is far away more, capacitance is more little, the high frequency intensity of passing through is more little, this infusion bag needs the high frequency of two kinds of intensity, movable capacitor board 3 moves to two different positions when just requiring work, one and fixed capacity plate close together, one far away with fixed capacity plate distance, capacitance value on the PLC controller sampling activity capacitor board 3, like this by setting the capacitance value of PLC controller, the accurate position of control activity capacitor board 3 just, thereby two kinds of high frequency output intensities that obtain setting
The high frequency output of this heat sealing machine requires weak earlier back strong, this is because infusion bag is wanted earlier plastic conduit and plastic sheeting welding, again around welding two plastic sheetings, but sometimes because mechanical disorder or error in operation, before welding, movable capacitor board 3 is not in initial position, just with the position of fixed capacity plate 4 close together, this just requires the machine position of monitor activities capacitor board constantly, so be provided with linear resistance 11 on the next door of movable capacitor board 3, the resistance of this linear resistance 11 is along with the mobile linearity that is of movable capacitor board 3 changes, the PLC controller is connected by circuit and linear resistance 11, to the contrast of taking a sample of the resistance of linear resistance 11, thereby determine the position of movable capacitor board 3 on screw rod 6, before each work, by the resistance on the PLC controller sampling linear resistance 11, control drive motors 5 driving activity capacitor boards 3 are to the initial position of setting, guarantee the strong order output in the weak earlier back of high frequency output, the running of entire machine all is subjected to the monitoring of PLC controller, improves the automaticity of producing.
