Description

Long-hair vibration ultrasonic system refers to an ultrasonic system that continuously works for a long time, mainly used for automatic machinery, such as non-woven mask equipment, non-woven bag production equipment, plastic bag equipment, etc. Due to production needs, the working current of the ultrasonic system is about 2 amperes, and long-term operation will generate a large amount of heat. If the heat cannot be effectively dissipated, faults such as mold overheating, ultrasonic overload, and frequent cracking of transistors will occur after a long time, which will affect the entire equipment. Operation, the product qualification rate is greatly reduced, therefore, must choose an excellent ultrasonic system. Different from other manufacturers, RPS-SONIC has been focusing on the optimization and upgrading of the ultrasonic system, using electronic components with better temperature resistance, using imported transistors, installing high-speed fans, speeding up the cooling speed, etc. At the same time, it creatively conducts overload destructive tests , adjust the working current of the system to 8 amps and then work continuously for 72 hours to test the load capacity of the entire ultrasonic system. After this test, the ultrasonic system of RPS-SONIC can output more stably and continuously to ensure product quality.

The ultrasonic hand welder transmits ultrasonic energy to the welding area through the upper weldment. Due to the large acoustic resistance of the welding area, that is, the interface between the two welding, local high temperature will be generated. In addition, due to the poor thermal conductivity of the plastic, it cannot be distributed in time, and it gathers in the welding area, causing the contact surface of the two plastics to melt rapidly. When the ultrasonic wave stops working, let the pressure continue for a few seconds to make it solidify and form, thus forming a strong molecular chain to achieve the purpose of welding, and the welding strength can be close to the strength of the raw materials.

Product principle

The ultrasonic welding machine converts the 50/60hz current into high-frequency alternating current through the ultrasonic generator, and inputs the electric energy into the ultrasonic transducer to generate mechanical motion of the same frequency. The mechanical motion is transmitted to the ultrasonic welding head through the amplitude modulator device, and the welding head transmits the received vibration energy to the joint of the workpiece to be welded. In the area of action, the energy is converted into heat energy by friction, which melts the plastic. The short-term pressure maintained on the workpiece after the vibration stops makes the two weldments solidify as a whole in a molecular link. Generally, the welding time is less than 1 second, and the obtained welding strength is comparable to that of the body.

Features

Compared with traditional processes (such as gluing, electric ironing or screw fastening, etc.), Skerry ultrasonic spot welding has significant advantages such as high production efficiency, good welding quality, environmental protection and energy saving. Portable ultrasonic welding machine is specialized in welding and riveting process of plastics, non-woven fabrics, leather products, chemical fiber cotton, etc. It has completely replaced the traditional organic melting point agent pasting process, and has the advantages of low energy consumption, high efficiency, no deformation, no pollution, firm welding, and easy operation. The hand-held ultrasonic welding machine can replace different ultrasonic welding heads according to the size of the riveting point of the welded product and the welding requirements, which is fast and convenient, and the cost is much lower than that of the special-purpose ultrasonic welding machine for automobile door panels, which meets the needs of customers.

Ultrasonic spot welding machine greatly shortens the processing time, the bonding between plastics can be completed in a few milliseconds using ultrasonic processing, the process is clean, stable and reliable, and the energy consumption is low. Ultrasonic energy is only used in the area that needs to be welded. Consumption, efficient and economical operation without preheating and heat preservation; no excess heat generated by the use of ultrasonic waves No need to use expensive and easily contaminated auxiliary materials such as adhesives, clasps or adhesives; environmentally friendly packaging after processing And it can be regenerated and can be sealed and welded through dirt (such as liquid, grease, powder, etc.) without affecting the welding effect.
