Description

Duplex position cloth welding equipment based on ultrasonic wave processing

Technical Field

The application relates to the field of cloth processing equipment, in particular to double-station cloth welding equipment based on ultrasonic processing.

Background

Ultrasonic welding is to transfer high-frequency vibration waves to the surfaces of two objects to be welded, and under the condition of pressurization, the surfaces of the two objects are rubbed with each other to form fusion between molecular layers. During welding, converting 50/60Hz current into 15, 20, 30 or 40KHz electric energy through an ultrasonic generator; the converted high frequency electrical energy is again converted by the transducer into an equally frequent mechanical motion, which is then transferred to the horn by a set of horn devices that vary the amplitude. The welding head transmits the received vibration energy to the joint of the workpieces to be welded, and the vibration energy is converted into heat energy in the area in a friction mode to form a local high-temperature environment, so that the workpieces to be welded are melted. Ultrasonic waves can be used not only to weld hard thermoplastics, but also to process fabrics and films.

The main components of the ultrasonic welding system comprise an ultrasonic generator, a transducer/horn/welding head triplet and a frame. When the ultrasonic wave acts on the thermoplastic plastic contact surface, tens of thousands of times per second high-frequency vibration can be generated, the high-frequency vibration reaching a certain amplitude is transmitted to the welding area through the upper welding piece, and the local high temperature can be generated because the acoustic resistance of the welding area, namely the interface of two welding areas is large. Thermal energy comes from the reciprocating movement of a workpiece at a certain displacement or amplitude on the other surface under a certain pressure. Once the desired degree of welding is achieved, vibration is stopped while still having some pressure applied to the two workpieces, allowing the just welded portions to cool and solidify, thereby forming a tight bond.

With respect to the related art described above, the inventors consider that there are the following drawbacks: in the process of carrying out cloth processing, the cloth after being cut in advance is required to be welded, the existing ultrasonic welding device comprises a workbench and a welding device arranged on the workbench, when carrying out welding operation, an operator places two groups of cloth on the workbench, the two groups of cloth are overlapped up and down and are positioned below a welding head, and because the space of a workshop is fixed, and each existing welding device can only complete one group of welding operation; there is room for improvement in the welding process because the efficiency of the welding process is low during the welding operation.
