How do you know the parameters of the ultrasonic welder? Do you know?

Setting the wave time:

The specific time should be determined according to the stroke and speed of the ultrasonic mold (welding head), and the purpose is to make the ultrasonic wave (the welding head) fall, and the ultrasonic wave is emitted immediately before the plastic part is hit.

Welding time setting :

According to the 'pressure of the pressure of the plastic parts' and 'the effect of welding' to determine; {for example: 1, if the plastic mouth of the welding joint 'splashing flash' means that the 'welding time' is too long or the pressure is too high or The 'falling stroke adjustment (limit) screw' limit is too low; if the weld is not melted enough, it happens to be the opposite of the former. 2. If the welding parts of the welded joint are inconsistent, it means that the pressure is different. This may be because the pressure is low, and the plastic parts are deformed more, the pressure test is increased, or the 'ultrasonic bottom mold' cannot make the plastic parts. The two halves can not be completely matched, and the film can be used to make the position of the 'ultrasonic bottom mold' insufficiently melted, and the test is repeated to achieve a good welding effect}.

Special attention should be paid to:

       When the 'welding time' and the 'falling stroke adjustment (limit) screw position' are the same, adjusting the air pressure value of the air pressure can also adjust the welding effect. Therefore, during normal use, it is necessary to keep the air pressure of the air pressure source higher than the set air pressure value.

Pressure (cooling) time setting:

       If the plastic part 'no deformation' 'no internal stress after welding' 'solidification is not very slow', usually do not select the cooling time value (or only take 1/5 seconds).

Trigger should be advanced; soldering should not be delayed; cooling should be as short as possible, probably choose time [about 0.3 seconds] and maintain pressure (cooling) time [0 seconds - exception for slow-setting plastics].

Adult back massage Pedicure Spa Chair It is divided into electric and robotic. Difference between robot and electric: 1. The robot has one more function than electric to insert audio data. 2. The back of the robot only has 4 massage bead up and down activities massage, electric backrest has 8 massage beads fixed massage. 3. The price of the robotic arm is 1,000 yuan more than that of the electric motor. There is an eggshell outside the massage chair. It mainly looks like high-end atmosphere. The chair neck and shoulder chair 4 kneading balls and the back waist a set of four kneading balls. Pinch massage, buttocks vibrating four vibrating cycle massage, the back of the chair lying back, the seat before and after manual remote adjustment, chair armrests have open cup holes, armrests can be up and down 90 degrees activities. The principle of the massage chair is to use mechanical rolling force and mechanical force to massage. For normal people, artificial massage can enhance the body's natural resistance to disease and achieve health effects. However, the mechanical massage of the massage chair is different from the manual massage. Although the massage chair has several contacts, it cannot select points, acupuncture points, and perform similar artificial massage actions, but imitates the actions of [kneading" and [pinching" by humans. Therefore, the massage chair can only eliminate fatigue, relieve discomfort, and play a relaxing role, and its strength is not easy to control, the strength is small, and the effect is not great. When the strength is large, muscle pain will be caused.
