Description

Technical Field

[0001] This utility model relates to the technical field of egg carton forming equipment, and in particular to a hot press mold connecting device for a packaging machine. Background Technology

[0002] Egg cartons are specialized containers used for packaging and transporting poultry eggs (such as chicken eggs, duck eggs, and quail eggs). Their primary function is to protect eggs from damage and contamination and to facilitate storage and sales. In the production process, waste paper is first vacuum-formed into wet blanks using a forming machine. These wet blanks are then hot-pressed. Existing egg carton forming machines use fixed pipes to connect the pre-pressing mold and the upper hot-pressing mold. This fixed installation of the pre-pressing mold and upper hot-pressing mold to the machine frame makes it difficult to switch their positions relative to the lower hot-pressing mold. Furthermore, the fixed piping requires a large number of pipes for connection to the upper hot-pressing mold, and disassembly and maintenance of these fixed pipes are also inconvenient. Therefore, a new hot-pressing mold connection structure needs to be designed to solve these problems. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a hot press mold connecting device for a packaging machine. The distribution pipes of the hot pre-press mold and the upper hot press mold are equipped with a first rotary joint, and a first flexible hose is rotatably connected to the first rotary joint. This allows the hot pre-press mold and the upper hot press mold to be slidably connected to the machine frame via a sliding block, facilitating the switching of their positions relative to the lower hot press mold. Furthermore, the first flexible hose can move with either the hot pre-press mold or the upper hot press mold. This direct connection of the first flexible hose to the distribution pipes of the hot pre-press mold and the upper hot press mold simplifies the piping setup, reduces the required pipework, and facilitates pipe disassembly and maintenance.

A first rotary joint 6 is provided on the diversion pipe 5, and a first flexible hose 7 is rotatably connected to the first rotary joint 6.

[0014] The working principle of the hot pressing mold connecting device for the packaging machine described in this utility model is achieved through the cooperation of the frame 1, the slide 2, the hot pre-pressing mold 3, and the hot pressing upper mold 4. Figures 1 to 3 As shown, a servo motor can be installed on the frame 1. The servo motor can drive the slide 2 to move back and forth along the frame 1 through a conventional drive structure with a screw and threaded seat. This is not described in detail. It is convenient to switch the positions of the hot pre-pressing mold 3 and the hot pressing upper mold 4 with the hot pressing lower mold. The flow pipe 5 of the hot pre-pressing mold 3 and the hot pressing upper mold 4 is equipped with a first rotary joint 6. A first flexible hose 7 is rotatably connected to the first rotary joint 6. The first flexible hose 7 can move with the hot pre-pressing mold 3 or the hot pressing upper mold 4.
