Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a high-frequency device for welding and forming a PVC folder. Background Art

[0002] PVC folders are folders made of PVC plastic. Currently, folders used in offices are basically made of this material. High-frequency welding machines are the preferred equipment for plastic heat sealing. The plastic folders to be welded are placed in the mold for positioning. The machine converts electrical energy into high-frequency electromagnetic field energy, and uses a specially designed electrode head to apply the electromagnetic field to the plastic parts to be welded. Under the action of the electromagnetic field, the molecules on the surface of the plastic parts will be subjected to strong vibration and friction, thereby generating heat, causing the plastic parts to reach the melting point in a short time. When the plastic parts reach the melting point, the electrode heads will quickly pressurize the plastic parts to further contact and form a weld in the molten state. Through the above steps, the high-frequency plastic welding machine can efficiently complete plastic parts in a short time. Therefore, the high-frequency device plays an important role in the welding and molding of PVC folders.

[0003] The existing high-frequency device for welding and forming PVC folders has some disadvantages. First, it is not easy to position the plastic parts. It is easy to cause the welding position to shift when the plastic parts of the folder are touched, affecting the welding effect. Second, the welding range cannot be adjusted, and the practicality is poor. Utility Model Content
