How to use high frequency welding machine

There are nine steps in the use of high frequency welding machine, which need to be operated in order

method/step

Connect the air source first:

Turn up the knob of the gas regulating valve to adjust the air pressure to the range of 4~7Kg.

Finally check the switch on the panel of the high frequency fusion splicer:

The high-frequency switch is in the "off" position, the manual/automatic selection switch is in the "manual" position, and the power switch is in the "off" position. Turn on the power inlet air switch and the main power switch on the side of the machine, and hear the sound of the fan rotating inside the machine. Turn on the power switch on the panel, observe that the power indicator light (green) is on, and the voltmeter indicates about 220V.

Up button adjustment:

Press the red up button on the motorized panel of the high-frequency welding machine to raise the upper template to the highest position. Push a push plate into the working position, and the magnets on the side of the push plate will attract the support plate to position the push plate.

Install upper mold:

Install the upper mold of the high frequency welding machine on the upper template, and the lower mold on the turntable.

Adjust the mold after installing the upper mold:

Press the green drop button on the panel to lower the upper die to a position close to the lower die. Turn the hanging mold screws at both ends of the upper mold lifting plate to adjust the left and right balance of the upper mold, and turn the four corner handle screws on the upper mold lifting plate to adjust the balance of the four corners of the upper mold. After adjusting the balance, tighten the adjustment screws. Move the position of the lower mold on the turntable, align it with the upper mold, and lock the pipe position screws on both sides after adjustment. Adjust the position of the other lower die on the turntable in the same way.

Wait for the high frequency mold to warm up and the thermostat:

A heating device and a temperature controller are arranged on the lifting plate of the upper mold. When preheating is required according to the product situation, it is necessary to turn on the thermostat and adjust the knob to set the temperature about 20 minutes before production. At this time, the red indicator light on the thermostat is on, and when the temperature reaches the indicator light, it goes out, and the production can begin. The preheating temperature should be determined according to the material and thickness of the object to be welded. Generally, PVC materials are preheated at about 120°C, and PET materials are preheated at about 80°C. Mold preheating can speed up production and increase output.

Place the spliced product in:

Put the lower half of the blister cover into the lower mold, put the packaged object, then align the upper half of the blister cover with the lower blister cover, turn the turntable to position the lower mold in the working area, press the down button, Make the upper mold descend and press the blister cover. Then install the grounding aluminum plate with the brass ring on the grounding bracket (note: the brass ring must be in reliable contact with the push plate). Turn the coherent knob on the front of the machine clockwise to make the pointer point to zero, set the descending delay time to about 1.5 seconds, the welding time to 10 seconds, the setting time to about 1.5 seconds, and the rising time to about 1 second. First put the high-cycle switch in the "OFF" position, then turn the automatic/manual selection switch to the "Automatic" position, the machine enters an automatic working process, and the welding time starts after a delay of 1.5 seconds. Rotate in several directions, observe the pointer of the ammeter rises slowly, observe the plastic cover being welded, press the red stop/up button when it is welded, the machine stops welding immediately, and the upper mold rises to the highest position. At this time, turn the automatic/manual selection switch back to the "manual" position, push the push plate to make the lower mold leave the working area, and take out the material to check the packaging welding effect. Re-set the welding time according to the actual situation (generally about 2~4 seconds), test the pressure again according to the previous method, and increase the welding current appropriately, so that the machine can weld the material well within the set welding time.

After the welding time is completed, it enters the cooling and setting time (set according to the situation). After the setting time is completed, the upper mold rises, and the rising height is determined by the set rising time. After several pressure tests and adjustments meet the requirements, the automatic/ The manual selection switch is placed in the "automatic" position for normal production. During normal production, the lowering time should be adjusted. It is required that the upper mold should lower and press the material within the lowering time, and it should not be too long to waste time. Note: Before each production, the machine must be powered on, and the electronic tube can be preheated for 15 minutes before production.

High frequency machine protection action and emergency stop switch:

No matter in the welding process of pressure test or normal production, if the mold sparks or the current exceeds the allowable value of the machine, the machine will automatically stop the welding process immediately to protect the mold, materials and precious parts of the machine. When an abnormality occurs during the welding process, the red emergency stop button can be pressed immediately, and the machine will immediately stop the welding process.

Follow-up of high frequency welding machine shutdown:

When shutting down, first turn off the power switch on the panel, and then turn off the power switch after the cooling fan continues to work for 5 minutes.
