Description

Prevent to stick up hot melt labeller of mark Technical Field The utility model relates to the technical field of container labeling machines, in particular to a hot-melting labeling machine capable of preventing label tilting. Background The outer surfaces of various container packages are generally labeled to introduce relevant information of products. The label is pasted in various ways, such as hot melt adhesive labeling, self-adhesive labeling and the like, wherein the hot melt adhesive labeling is suitable for quick labeling of a production line, and has the advantages of simple process, low cost, firm adhesion, low storage environment requirement and the like, so that most of the hot melt adhesive labeling ways such as milk barrels, drinking water bottles and the like are adopted. In chinese patent entitled "container labelling machine", application number "CN202180037723.7", a hot melt adhesive labelling machine is disclosed, "the label 6 obtained after cutting can be carried to a carrying drum 25 using a cutting drum 9, the carrying drum is adapted to bring the label 6 received from the cutting drum 9 into sequential contact with the corresponding container 4 transported by the transporting device 3, the adhesive applying roller 24 adjacent to the carrying drum 25 applies the adhesive to both ends of the label 6", in actual production, the label sticking phenomenon, that is, the edge of the label attached to the container is lifted or misplaced, the label is re-stuck to be repaired once the label sticking phenomenon occurs, the label is seriously even required to be torn off, and then the label is returned to the production line for re-labeling, seriously affecting the production progress, which is the labelling machine employing the above technical scheme. The reason for this is that in the existing labeling machine, both ends of the cut label cannot be well attached to the carrying roller, and when in contact with the adhesive applying roller, wrinkles are generated, so that the end of the label cannot be fully coated with the glue. In order to solve the defects in the existing labeling machine, a hot-melt labeling machine capable of preventing label from being tilted is improved and developed. Disclosure of utility model The utility model aims to provide a hot-melt labeling machine capable of preventing label from being tilted, which is used for solving the label tilting phenomenon in the container labeling process.
