Description

[0002] The cartons produced by packing manufacturers are usually sheet cartons, that is, cartons folded along the diagonal, such as Figure 1 Before using these cartons, a carton opener is needed to open the sheet cartons into a three-dimensional structure and seal the bottom. Figure 1 Bend the four paper covers on the middle and rear sides inwards by 90° and seal them with tape.

[0003] When the existing carton opener is used, when it is necessary to open and seal the bottom of sheet cartons of different specifications and sizes, it is necessary to manually adjust the structure of multiple positions of the carton opener according to the actual size of the sheet cartons, such as manually adjusting the distance between the suction cups on the clamping mechanism, the distance between the clamping conveyor belts, etc. Since there are many adjustment points and they need to be adjusted manually, it is impossible to quickly change and adjust the applicability according to the actual size of the carton, which affects the opening efficiency and also reduces the scope of application of the carton opener.
