Installation and debugging of ultrasonic plastic welding machine

Ultrasonic plastic welding machine installation procedures:

1. The welding machine should be placed on a solid, level workbench. There should be more than 150mm of space behind the machine to facilitate ventilation and heat dissipation.

2. To ensure safe operation, the machine must be reliably grounded, and the resistance to ground must be less than 4 ohms.

3. Insert both ends of the Sanyi control wire into the three-pin socket at the rear of the welding machine, and tighten the nut.

4. Place the selector switch in the manual position.

5. Tighten the four lifting screws to fix the ultrasonic vibrator head, but do not use excessive force to avoid slipping the teeth.

6. Clean the contact surface between the upper welding mold and the ultrasonic vibrator head, connect it with screws, and lock it with the special wrench that comes with it. The locking force distance is 25 Newton/meter.

7. Connect the air pipe of the external air source to the air filter of the welding machine.

8. Sonic inspection procedure:

In order to maximize the use of the welding machine and maintain the performance of the welding machine and safe production, every time the machine is used or the welding mold is replaced, The vibration system and vibration level of the welding machine must be adjusted, so this sonic testing procedure is very important.

A. Before inspection, the upper welding mold and the ultrasonic vibrator head must be tightly locked and the upper welding mold must not touch the workpiece during inspection.

B. Turn on the power switch, and the power indicator light will be on.

C. Open the door of the side cover.

D. Press the selector switch to the sonic detection position and observe the indication value of the amplitude meter. The sonic detection switch cannot be pressed continuously for more than 3 seconds each time.

E. Rotate the sonic detection screw clockwise and counterclockwise so that the amplitude meter pointer is at the lowest scale value. Note: The amplitude meter pointer can be adjusted below the 1.2 (or 100) scale value, and ensure that it is at the lowest scale position. The vibration system and vibration system spectrum of the welding machine are the best.

[Note]:

⒈ Adjust the sound wave selection screw, and the pointer of the amplitude meter will swing left and right, but it does not indicate the size of the power output, but only indicates the vibration system and vibration The degree of resonance of the system. The smaller the scale value, the better the degree of resonance.

⒉ The amplitude meter indicates the degree of resonance when oscillating with no load, and indicates the output energy when oscillating with load.

⒊ Sound testing must be done before welding to ensure the resonance of the oscillation system and the vibration system.

⒋ After replacing the welding mold, remember to do the sonic testing procedure.

⒌ During adjustment, if the overload indicator light is on, immediately release the sonic check button. After about 1 second, turn the sonic adjustment screw for sonic selection adjustment.

⒍ Correct tuning is very important. If it cannot be adjusted to the normal state and cannot meet the requirements of item 5 of the sonic detection procedure, please send it for repair immediately. Do not use it reluctantly to avoid expanding the fault.

⒎ The working air pressure cannot exceed 5kg/cm.

⒏ Mold calibration procedure:

In order to achieve the maximum energy of the machine, the space between the upper welding mold and the workpiece The distance should be shortened as much as possible, but the necessary distance should still be left to facilitate the placement and removal of the workpiece. The maximum stroke of the lifting table is 75mm, so before mold calibration, when the upper welding mold is determined to be at its maximum stroke, it will not touch the workpiece.

a) Place the selector switch in the manual position and adjust the pressure adjustment knob so that the pressure gauge indicates about 0.2Mpa (approximately the minimum pressure that can make the welding head rise)

b) Place the lower welding mold on the work surface, and then place the workpiece in the lower welding mold.

c) Loosen the locking handle of the machine body, turn the lifting handwheel so that the distance between the upper welding mold and the workpiece is greater than 75mm, and tighten the locking handle.

d) Press the two lowering buttons with both hands to lower the upper welding mold.

e) Loosen the four vibrating head fixing screws, rotate the upper welding mold to match the workpiece, and then tighten the four vibrating head fixing screws.

f) Loosen the stop screw and rotate the stop screw (M12x1) so that it contacts the lifting platform. Press the emergency rising button to raise the upper welding mold, and then rotate the stop screw about 7mm.

g) Press the two lowering buttons with both hands to lower the upper welding mold. Loosen the locking handle of the machine body, turn the lifting handwheel, slowly lower the upper welding mold, and move the lower welding mold at the same time to make the working surface and the upper welding mold contact evenly, and lock the locking handle of the machine body.

h) Press the emergency rise button to raise the welding head, rotate the stop screw, and lower it about 2mm. The specific size depends on the workpiece, so that the stop screw is out of contact with the lifting during operation. But when there is no workpiece in the lower welding mold, the stop screw can prevent the upper welding mold from touching the lower welding mold and protect the machine parts from damage.

i) Fix the lower welding mold on the workbench with a screw pressure plate Above.

j) The above operation is the mold calibration step. For more accurate mold calibration, you must observe and adjust while doing the trial welding. You can use copy paper between the workpiece and the upper weld to observe the upper weld. After the mold is pressed down, according to the indentation shown on the white paper, use a thin gasket to adjust the bottom of the welding mold according to the depth of the indentation, so that the welding surface of the workpiece is evenly pressed.

k) Belt Plane adjustment method for adjusting the direction and level of the welding head of the screw model: (outline as shown)

1. The accumulated water in the air filter should be discharged in time before it overflows.

2. Every time the welding machine is used for one month, the sliding parts should be wiped clean and re-coated with high-quality lubricating grease.

3. It is strictly forbidden to use various fluxes when cleaning the side panels and surfaces of the welding machine. Use neutral detergent and wipe gently.

4. Every six months, the dust in the machine should be blown away with dry compressed air.

Common sense identification method:

1. Look at the length of time the company has been producing ultrasonic plastic welding machines. Generally speaking, the more experienced it is , the more technically proficient the person is.

2. Look at brand awareness. Of course, the most famous brands have been tested by the market and their credibility is worthy of trust.

3. Look at the production process of ultrasonic plastic welding machine. Good production process can create better products.
