Fixed-angle pressing and folding mechanism for packaging carton

Abstract

The invention relates to a fixed-angle pressing and folding mechanism for a packaging carton. The fixed-angle pressing and folding mechanism comprises a bottom plate, wherein a flat panel is mounted on the upper end surface of the bottom plate; the left end of the flat panel is equipped with a folding plate through a hinge; the folding plate can freely rotate at the left end of the flat panel; a precision shaft is arranged on the middle shaft of the front end of the folding plate; a limiting arc frame is mounted on the outer wall of the precision shaft in a sliding fit mode; an L-shaped bracket is welded on the back of the limiting arc frame; the bottom end of the L-shaped bracket is mounted on the bottom plate; the L-shaped bracket achieves the effect of fixing and supporting the arc-shaped frame rack; an angle value is set on the front end surface of the limiting arc frame, and angle rotated by the precision shaft can be seen through the angle value; and lug bases I are mounted on the back of the folding plate, and a hydraulic cylinder I is mounted between the lug bases I through a pin roll. The fixed-angle pressing and folding mechanism can realize the fixed-angle automatic pressing-folding function of cartons, and has the advantages of being simple and convenient in operation, high in pressing-folding speed, flat in pressing-folding, precise in pressing-folding angle, high in working efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of carton processing, in particular to a fixed-angle creasing mechanism for packing cartons. Background technique [0002] In the existing carton processing process, after the batch processing is completed, it is often encountered that certain cartons are creased at a specified angle. Since the number of cartons that need to be creased and folded at a specific position is small, it will not be on the assembly line. Automatic creasing, usually manual creasing, but the existing carton manual creasing and punching methods have defects such as complicated operation, slow creasing speed, uneven creasing, difficult control of creasing angle and low work efficiency. Contents of the invention [0003] In order to solve the above problems, the present invention provides a fixed-angle creasing mechanism for packaging cartons, which can solve the problems of complex operation, slow creasing speed, uneven creasing, di...
