[0002] Packaging boxes are containers used to package goods. They are usually made of materials such as paper, plastic, metal, and glass. They serve to protect goods, facilitate transportation, and promote sales. Plastic materials have good flexibility, transparency, and water resistance, and can be made into packaging boxes of various shapes. Because plastics are thermoplastic, common plastic packaging boxes are generally formed by thermoforming.

[0003] In the modern packaging industry, plastic packaging boxes are widely used in many industries such as food, medicine, and electronics due to their good plasticity, water resistance, and cost advantages. As one of the mainstream production processes for plastic packaging boxes, thermoforming is favored for its ability to efficiently produce packaging boxes with regular shapes and precise dimensions. However, existing thermoforming equipment still has some problems that need to be solved in actual production.

[0004] Because plastic materials adhere tightly to the mold surface during thermoforming, they generate significant adhesion and friction, which can easily lead to quality problems such as scratches, deformation, and breakage of the packaging boxes, reducing the product yield.

[0005] Therefore, a highly efficient fully automatic packaging box forming equipment is proposed to address the above problems. Utility Model Content

[0031] The ejection assembly 10 includes mounting grooves 101 respectively opened on the hot pressing male mold 9 and the hot pressing female mold 4. A spring telescopic rod 102 is provided in the mounting groove 101, and the end of the spring telescopic rod 102 is connected to the ejection plate 103.

[0032] The airflow assembly 11 includes an annular pipe 111 located at the bottom edge of the ejector plate 103. An airflow nozzle 112 is provided on the outside of the annular pipe 111. The annular pipe 111 is connected to a vertical pipe 113. The end of the vertical pipe 113 passes through the hot-pressing mold 9. The end of the vertical pipe 113 is connected to a flexible hose 114. The end of the flexible hose 114 is connected to a guide pipe 115. The guide pipe 115 is connected to an air pump 116.

[0033] Specifically, guide holes 12 are provided at the four corners of the bottom movable frame 3 and the top movable frame 8, and support rods 5 are provided in the guide holes 12 to ensure the stability of the hot pressing male mold 9 and the hot pressing female mold 4 when they are displaced.

[0039] Working principle and process: When the plastic sheet passes through the corresponding position between the hot-pressing male mold 9 and the hot-pressing female mold 4, the bottom hydraulic cylinder 2 and the top hydraulic cylinder 7 are activated, causing the hot-pressing male mold 9 and the hot-pressing female mold 4 to move closer together and close. Under the action of hot pressing, the plastic sheet gradually forms a packaging box shape. During demolding, the hot-pressing male mold 9 and the hot-pressing female mold 4 move away from each other. Under the pressure release of the spring telescopic rod 102 of the ejection assembly 10, the ejection plate 103 moves, thus lifting part of the packaging box. At the same time, the airflow assembly 1... When the airflow nozzle 112 of 1 is exposed, the air pump 116 is started. The airflow passes through the guide pipe 115, hose 114, vertical pipe 113, and annular pipe 111 and is then sprayed out from the airflow nozzle 112. The airflow flows along the gap between the packaging box and the mold to achieve the demolding effect. While improving the demolding effect, the airflow flows along the surface of the packaging box, which can quickly remove the heat on the packaging box and achieve the cooling effect.
