Digital Ultrasonic Bonding Machine
Jiayuanda Ultrasonic Plastic Welding Equipment-H80/80S. It is an intelligent digital ultrasound welding machine researched and developed by us. We use perfect and optimized real-time phase-locked loop tracking technology in developing this series, which achieves more stable and reliable operation. Flexible human-machine interface configuration gains more flexible product application....
The Digital Ultrasonic Bonding Machine has the advantages of simple operation, fast welding speed, high welding strength, and high production efficiency. For some products with larger dimensions and higher welding area and strength, the power selection of ultrasonic plastic welding machines is particularly important. For many brands plastic welder, 15KHz 4200W and above power is the most common model, and the biggest drawback of this model is high noise
Which is widely used to solve the welding of various paper bags at the sides, bottom, and other positions. Common products such as wine boxes, takeout boxes, gift bags, archive bags, etc.
Component Function Description of Digital Ultrasonic Bonding Machine
1. Delay time setting: Adjust the start vibration time to start vibration within 0-9.99 seconds after the limit switch is activated.
2. Welding time setting: Adjust the welding time to vibrate within the range of 0-9.99 seconds at the end of the delay time.
3. Curing time setting: Adjust the cooling and setting time at the melting point of the working material after vibration to within the range of 0-9.99 seconds.
4. Pressure regulating valve and pressure gauge: used to indicate the working pressure and adjust the air pressure setting.
5. Power switch and light: Control of power switch and light signal indicating open circuit.
6. Acoustic overload light: It displays abnormal acoustic overload and needs to be adjusted until the overload light does not display. (If it still cannot be lifted, please call for consultation)
7. Welding head: transmits vibration energy to the working object for welding.
8. Rise/fall buffer adjustment: The adjustment hole is located on the side of the machine and can be adjusted appropriately to ensure moderate lifting inertia.
9. Adjustment of descent speed: Adjust the descent working speed reasonably and appropriately.
10. Welding position window: Check the condition of the welding head pressing the working object during normal welding.
11. Fine adjustment screw: used to limit the descent of the cylinder when welding and melting are fast or the overall dimensions need to be precise. 12. Horizontal fine adjustment screw: Adjust these four screws to evenly press the welding head onto the workpiece.
13. Body fixing handle: used to tightly fix the body and support.
14. Output cable and socket: used to connect the body transducer system with the vibration box circuit.
15. Control cable and socket: used to connect the body control unit with the automatic control circuit of the vibration box.
16. Welding lowering button: A button for lowering during automatic/manual operation.
17. Emergency ascent button: used for emergency ascent or manual ascent.

FAQ：
Problems prone to ultrasonic welding:
Improper coordination of ultrasonic welding conditions: the conditions for ultrasonic operation refer to the settings of output power (number of segments), pressure (dynamic pressure and static pressure), welding time, hardening time, delay time, etc. of the machine. Let's take the supersonic waveguide fuse as an example. When we implement ultrasonic welding, if the pressure is too large and the cylinder drops and buffers too fast, it is easy to flatten the ultrasonic waveguide fuse line. Although it seems that the product has been tightly connected, the fuse line has been squeezed and sagged, losing the welding effect, forming a forced welding of plastic surface to surface, rather than a triangular point, which produces a false welding.
Improper coordination of plastic product materials: the melting point of each plastic material is different. For example, the melting point of ABS plastic material is about 115 ℃, the melting point of Nilon is about 175 ℃, the melting point of PC is above 145 ℃, and the melting point of PE is about 85 ℃. For example, the melting point difference between ABS and PE is too large, and ultrasonic welding is bound to be difficult. There is also a gap between ABS and PC materials, but the gap is not so big as the previous one, so they can be welded. However, under the same ultrasonic power and the same energy expansion, different plastic materials can never be better than the same material.
Insufficient ultrasonic output energy: When customers purchase ultrasonic welding machines, it is usually difficult to predict the specifications of future product development, so they will encounter situations where large product objects exceed ultrasonic standard welding. At this time, under the budget of not increasing the cost, we have to use the existing equipment for production. In the case of using a small machine as a large object, the usual methods are several times of welding, increasing the ultrasonic output power (increasing section) or increasing the welding time and pressure. However, this also leads to unstable quality, because voltage and air pressure directly affect the stability of ultrasonic output power.
Unstable quality of welding products: the main reason for unstable quality is that the output power is unstable, which leads to the failure to form stable friction heat energy.
