Before using the ultrasonic lace machine, it must be tested. This is to give full play to the performance of the ultrasonic lace machine and maintain the normal use of the machine itself, thereby adjusting the vibration frequency between the generator and the transducer system. this point is very important. Next, REHOW Machinery will share with you the testing method of the ultrasonic lace machine to help you make better use of the ultrasonic lace machine.
Before adjusting the vibration frequency between the generator and the transducer system, as a user, you need to ensure that the position between the welding head and the sub-rod of the ultrasonic lace machine is completely locked. After adjusting the vibration frequency, the welding head used cannot touch other objects. If contact occurs, it needs to be wiped clean. Then, turn on the power switch of the ultrasonic lace machine. At this time, after the power indicator light is on, it can indicate that it has been turned on. If it does not open, it may be that the joint is loose and needs to be adjusted in time. Otherwise, the machine may malfunction and the following steps cannot be performed at this time.
If the indicator light is normal, you can press the switch of ultrasonic detection. At this point, keep an eye on the load meter. Generally speaking, when the pointer of the ammeter exceeds two amperes or exceeds 30%, the test switch will be pressed. This time is quite short, the operator must observe carefully. Then adjust the inductance part of the vibration frequency, and rotate it left and right until it reaches the parameter of the ammeter, which is above the relatively small part. Usually between 5% and 15% of the ammeter. Since the ultrasonic lace machine itself has a fixed clamping position, the adjustment range is usually only between 360 degrees. If it is found that the frequency of the welding head is far from the original parameters, it is necessary to open the top cover of the ultrasonic lace machine and remove it for a new adjustment. If you are not a professional, you can seek help from the manufacturer, and do not disassemble it at will, so as not to damage the parts of the ultrasonic lace machine.
In order to improve the production efficiency of the ultrasonic lace machine, generally speaking, the distance between the welding head and the plastic parts should be reduced as much as possible, but enough space should be left for everyone to take and place the plastic parts anytime and anywhere.
In the past two years, people’s demand for masks has increased, so many mask manufacturers have paid more attention to the working efficiency of ultrasonic lace machines. In order to improve the production efficiency of the ultrasonic lace machine, it is generally necessary to adjust the distance between the welding head and the plastic part to shorten the distance, but it is also necessary to leave a certain space for picking and placing materials.
In the process of producing masks, the operator needs to put the plastic parts on the base of the ultrasonic lace machine, adjust the air pressure to about 2 kg, and then use the welding head part of the ultrasonic lace machine to control its movement up and down through the lifting switch, so that the probe and the plastic Align the parts, then select the appropriate distance between the welding head and the plastic part, and lock the fixed handle. At this time, the staff will adjust the limit bolt to lower it. After the plastic is pressed, there is a certain space, generally about 0.2 mm. For some parts with a high welding depth, this space should be increased. You can adjust the welding holding time, test welding Press pressure etc. to control this space.
Then observe the manufactured samples. If the welding is found to be uneven, the base balance of the ultrasonic lace machine needs to be adjusted. Generally speaking, if the welding part dissolves seriously, it should be lowered. Otherwise, you need to place a piece of paper on the base, and adjust the position by raising the base to make it fit. Generally speaking, there are mainly 9 factors that affect the processing of plastic parts, namely, the design of the welding line, the contact surface, the shape and size of the plastic part, the material of the plastic part, the distance between the welding surface and the welding head, the size of the welding head, The design size and precision of the welding head, the pressure of the welding pressure, the selection of time parameters, etc.
As we all know, the ultrasonic lace machine forms a certain wave on the object through vibration, and the conditions for the formation of this wave must meet two conditions, namely, the propagation medium and the vibration source. The classification of waves is mainly divided into transverse waves and longitudinal waves according to the direction of vibration and propagation, and can also be divided into sound waves, infrasound waves and ultrasonic waves.
