Full-automatic plastic bag labeller

Abstract

Disclosed is a full-automatic plastic bag labeller. The full-automatic plastic bag labeller comprises a machine frame, a labelling mechanism, a stacking mechanism and a turnover mechanism, wherein thelabelling mechanism, the stacking mechanism and the turnover mechanism are arranged on the machine frame. The stacking mechanism comprises a stacking platform. The labelling mechanism is located above the stacking platform, and comprises a label covering assembly. The label covering assembly comprises at least one label covering air cylinder, wherein the stroke of each label covering air cylinderis perpendicular to the stacking platform. The turnover mechanism comprises a lifting air cylinder, at least one vacuum suction device, a press rod and a poking rod, wherein the lifting air cylinderis fixed to one side of the machine frame, the stroke of the lifting air cylinder is perpendicular to the stacking platform, the vacuum suction devices are driven by the lifting air cylinder to ascendand descend, the press rod can be attached to the stacking platform, and the poking rod can get close to / keep away from one side of the press rod to conduct reciprocating movement. Due to the fact that the turnover mechanism is arranged to conduct paging labelling operation on plastic bags placed on the stacking platform so as to replace an existing conveying type labelling mode, the full-automatic plastic bag labeller is suitable for labelling operation of large-sized plastic bags or ultra-thin plastic bags, and the labelling efficiency is substantially improved.

Description

technical field [0001] The invention relates to a labeling pen, in particular to an automatic plastic bag labeling machine. Background technique [0002] Labeler is a device that pastes rolls of self-adhesive paper labels (paper or metal foil) on PCBs, products or prescribed packaging. Labeling machines are an integral part of modern packaging. The utility model whose notification number is CN205470192U discloses a kind of "automatic card labeling machine", including a frame, a conveying mechanism, a card dividing mechanism and a header module. The target objects are coded on the card sorting mechanism, pushed to the conveying mechanism one by one, and then conveyed to the header module through the conveying mechanism, and the label is attached to the surface of the object by the header module. [0003] The card sorting mechanism of the existing labeling machine generally adopts the form of upper and lower transmission rollers plus a conveyor belt, which relies on the fric...
