When ultrasonic equipment is used, depending on the material and the welding environment, sometimes it is some special conditions of the ultrasonic welding machine itself, and some adjustments and preparations need to be made before welding. How to do it in detail, let's take a look.

1. Assemble the welding head:

(1) First wipe the transducer (CONE), the welding head (HORN) and the welding head screw with alcohol or gasoline, and then apply a thin layer of the welding head screw, the transducer and the welding head joint surface. Yellow grease then locks the welding head screw on the welding head. Note: If the joint surface of the transducer and the welding head is damaged, the transmission efficiency of vibration will decrease, so care should be taken for maintenance.

(2) Tighten 4 welding head level adjustment screws to fix the transducer at the middle position of its rotation range.

(3) Screw the welding head into the transducer by hand until it cannot rotate.

(4) Tighten the welding head with the welding head locking wrench (about 300Kg/cm torque). At this time, pay special attention to not allowing the transducer to rotate to prevent the tip from twisting. (If rotation is found, the 4 welding head level adjustment screws should be tightened more).

2. Welding head adjustment:

(1) Preparation for adjustment:

a. Turn on the air pressure source and adjust the pressure to 2kg/C㎡;

b. Turn on the main power switch on the vibration box, and the power indicator light is on.

(2) Adjustment of welding head direction:

Loosen the 4 horizontal adjustment screws, align the position of the welding head with the work object, and then press the body lift switch to press the welding head against the work object.

(3) Level adjustment of welding head:

Gently pat around the welding head to make the welding head match the working object, and fix 4 horizontal adjustment screws on average.

(4) Adjust the height of the welding head:

If the welding of the work requires preparation for the height, adjust the lowest point fine-tuning screw to the most appropriate position of the lifting cylinder after welding.

(5) Preparation for welding of ultrasonic plastic welder:

According to the condition of the work, set the number of output stages in the appropriate position. (The life should be maintained from the low stage count) Press the sonic check switch again, and turn the sonic adjustment screw, so that the indication of the amplitude meter is at the lowest scale. Note: Press the sonic check switch and press it for three seconds to stop the one-second intermittent mode to maintain the life of the vibrator.

Through the introduction of the above knowledge, we have a more detailed understanding of the ultrasonic welding machine. When welding plastic and plastic products, the ultrasonic welding machine can also be better used to maximize the efficiency while ensuring the service life of the ultrasonic welding machine.
