Title:
TONGUE FOLDING ASSEMBLY, BOX SEALING DEVICE, PACKAGING MACHINE AND COMPUTER-READABLE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/169097
Kind Code:
A1
Abstract:
A tongue folding assembly, a box sealing device, a packaging machine, and a computer-readable medium. The tongue folding assembly (1) is used for bending a main cover (1012) of a packaging box (101) to form an insertion tongue (1016), and comprises a first base plate (11) having a first inclined face (111), a second base plate (12) which can bend the main cover to a first preset position in the direction of the first inclined face, and a pressing member (13) which can press the main cover onto the first inclined face. The box sealing device (2) comprises the tongue folding assembly, and a tongue inserting assembly (21) for inserting the insertion tongue into the packaging box. The packaging machine comprises the box sealing device. The computer-readable medium comprises a preset program, wherein the preset program is executed to implement the following steps: the first base plate and the second base plate are clamped to bend the main cover toward the first inclined face to the first preset position, and the pressing member presses the main cover onto the first inclined face to form the insertion tongue. The insertion tongue formed in two steps effectively avoids damage to the main cover during one-step bending, and can also prevent the situation wherein the insertion tongue is too large or too small due to the bending position during one-step forming not being correct.
