Description

Paperboard forming machine and box manufacturing equipment equipped with the same The present invention relates to a cardboard forming machine. More specifically, it relates to a cardboard forming machine required when folding cardboard to produce a box. Boxes are used to accommodate various contents, facilitating storage and transportation, while protecting the contents from external impacts and foreign substances. Boxes are formed from various materials; in particular, in the case of boxes made of paper materials such as corrugated cardboard, the cardboard is folded to form a rectangular box. Generally, since box manufacturing is performed manually by workers one by one, there is a problem in that work efficiency is significantly low and a large amount of time and labor is required. FIG. 1 is a drawing showing a box manufacturing apparatus including a cardboard forming machine according to one embodiment of the present invention. FIGS. 2 and FIGS. 3 are drawings showing a cardboard forming machine according to an embodiment of the present invention. FIG. 4 is a drawing showing a cardboard being formed in a cardboard forming machine according to one embodiment of the present invention. FIGS. 5 and 6 are drawings showing the cardboard forming section of a cardboard forming machine according to one embodiment of the present invention. FIGS. 7 to 9 are drawings showing a cardboard box making machine of a box manufacturing device according to one embodiment of the present invention. FIGS. 10 to 12 are drawings illustrating the operation of a cardboard box making machine according to an embodiment of the present invention. FIGS. 13 to 15 are drawings showing a tray supply unit and a tray insertion unit in a cardboard box making machine of a box manufacturing device according to one embodiment of the present invention. The present invention is capable of various modifications and may have various embodiments; specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the present invention to specific embodiments, and it should be understood that it includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the present invention.
