Automatic packaging film corner cutter for packaging box

Abstract

The invention discloses an automatic packaging film corner cutter for a packaging box. The automatic packaging film corner cutter comprises a flattening device and two corner cutting devices which arearranged in sequence, and a transport mechanism for transporting materials is installed above the flattening device and the corner cutting devices; the flattening device comprises four sets of flattening units separately corresponding to the four sides of the packaging box, each set of the flattening units comprises two slidably arranged moving parts and the sliding directions of the two moving parts are opposite, and the sliding directions of the moving parts of the adjacent flattening units are perpendicular; and the corner cutting devices each comprise two sets of symmetrically arranged corner cutting units, each set of the corner cutting units comprises a straightening device for straightening a packaging film and a corner cutting clamping knife assembly for corner cutting, the cornercutting clamping knife assemblies each comprise a first clamping knife and a second clamping knife which are correspondingly disposed on both sides of the straightening devices, and heating members are mounted on the sides, close to the straightening devices, of the first clamping knifes. The automatic packaging film corner cutter can effectively cut the sharp corners of the packaging film on thepackaging box, the process is simple, the degree of automation is high, and the packaging film has a good coating effect after corner cutting.

Description

technical field [0001] The invention relates to the field of packaging, in particular to an automatic angle cutting machine for packaging film used for packaging boxes. Background technique [0002] After many products are put into the packaging box, a layer of packaging film needs to be covered on the surface to prevent the surface of the packaging box from being worn or scratched. Such as figure 1 As shown, the packaging box generally has a cuboid structure, and the packaging film covers the packaging box. The packaging film protrudes at the four sides of the packaging box to form sharp corners, which need to be processed. The general processing method is to fold the corners. This method has complicated procedures and needs to be equipped with many devices to cooperate with it. The cost is also high, and the degree of automation is low, and the work efficiency is also slow. Contents of the invention [0003] In order to solve the above technical problems, the present i...
