Hot-melt glue labelling machine

Abstract

The invention discloses a hot-melt glue labelling machine. The hot-melt glue labelling machine comprises a machine frame, a dispensing mechanism, a label cutting mechanism, a labelling mechanism, a control box, a conveying belt and a label conveying mechanism. The label conveying mechanism comprises a label wheel and a vacuum drum. A negative pressure space with one face being provided with an opening is arranged in the vacuum drum, and the opening is connected with a draught fan. Air suction holes communicating with the negative pressure space are formed in the side face of the vacuum drum. Labelled paper can be adsorbed onto the side face of the vacuum drum after extending out of the label wheel, and the vacuum drum rotates to drive the labelled paper to pass through the dispensing mechanism, the label cutting mechanism and the labelling mechanism in sequence. The dispensing mechanism coats glue onto the labelled paper, the label cutting mechanism can cut off the labelled paper and the labelling mechanism can paste the labelled paper onto bottles. According to the hot-melt glue labelling machine, the labelled paper can be adsorbed through the air suction holes in the side face of the vacuum drum, and the effect of fixed conveyance of labels can be achieved; and meanwhile, the labels can be conveyed flatly due to arrangement of the multiple air suction holes, wrinkling of the labels is prevented, the labels can be pasted onto the bottles more flatly and firmly, and thus labelling quality is improved.

Description

Technical field [0001] The invention relates to a packaging machine, and more specifically to a hot melt adhesive labeling machine. Background technique [0002] Hot melt adhesive labeling machine is a kind of packaging machinery used to label bottles and is widely used in various fields. The existing hot-melt adhesive labeling machine conveys the label paper after the label paper is tightened by the runner and the label wheel. However, the label paper is prone to skew during the conveying process, which leads to problems such as wrinkles and incorrect position after the label is attached to the bottle. Summary of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a hot melt adhesive labeling machine to prevent the label from shifting during the transfer process. [0004] In order to achieve the above objectives, the present invention provides the following technical solutions: a hot melt adhesive labeling machin...
