Label cutting device for hot melt adhesive labeling machine

Abstract

The embodiment of the invention provides a label cutting device for a hot melt adhesive labeling machine. The label cutting device comprises a frame body of a rectangular frame structure, a label cutting shaft is rotatably arranged in the frame body, moving cutters are symmetrically arranged on the label cutting shaft, a label cutting rotary drum is arranged on the label cutting shaft and located between the moving cutters, and cutting edges of the moving cutters are higher than the peripheral face of the label cutting rotary drum; and an air distribution disc is arranged on the inner wall of the top face of the frame body and arranged on the periphery of the label cutting shaft in a sleeving manner, the bottom face of the air distribution disc is attached to the top face of the label cutting rotary drum, vent holes are formed in the top face of the label cutting rotary drum, and label suction holes communicated with the vent holes are formed in the side face of the label cutting rotary drum. A static cutter mounting seat is arranged on the side surface of the frame body, a static cutter is arranged on the static cutter mounting seat, and the cutting edges of the moving cutters can be tangent to a cutting edge of the static cutter in the process that the moving cutters are driven by the label cutting shaft to rotate. According to the scheme provided by the embodiment of the invention, after the gap between the moving cutters and the static cutter is adjusted, the label cutting shaft only needs to drive the moving cutters to rotate according to the constant rotating speed, so that continuous and stable label cutting can be carried out, and the label cutting stability is high.

Description

technical field [0001] The invention relates to the technical field of labeling machine equipment, in particular to a label cutting device for a hot melt adhesive labeling machine. Background technique [0002] The hot melt adhesive labeling machine can be used for full-circle labeling, and is widely used in the labeling of mineral water bottles and other bottles. As an important part of the hot melt adhesive labeling machine, the label cutting device is used to cut the label. [0003] In the related art, in order to improve the efficiency of label cutting, a double-flying knife label cutting device is proposed. The device adopts a double-moving knife cutting label combination structure. This requires that the driving coordination between the two power mechanisms have a high degree of synergy. Once the driving coordination deviates, it will lead to the failure of the label cutting and the poor stability of the label cutting. Contents of the invention [0004] Aiming at t...
