This box is lightweight, durable, and easy to clean, so it has been widely used in various occasions. In the production process of plastic folding boxes, an ultrasonic plastic welding machine is required for welding operations. Ultrasonic welding is a process that uses high-frequency vibration energy to achieve the connection of plastic materials. This equipment can generate high-frequency vibrations, causing the plastic material to generate high temperature and pressure locally, thereby achieving welding. In the production process of plastic folding boxes, it is often necessary to use an ultrasonic plastic welding machine to perform multi-point welding inside the plastic folding box. Whether the welding points are neat depends entirely on the operating experience of the operator. At the same time, the neatness of the welding points will affect the aesthetics of the finished plastic folding box. Therefore, the quality of the finished plastic folding box has a certain randomness. In order to make the finished plastic folding boxes have good quality, an internal welding device for the plastic folding box is required. Utility Model Content
