Adaptive label merging device for labeling machine

Abstract

The invention relates to an adaptive label merging device for a labeling machine, and belongs to the technical field of folded labeling. According to the adaptive label merging device for the labelingmachine, labeling objects with different pipe diameters can be subjected to folded pasting of labels, and the working efficiency and the labeling quality of the folded labeling machine can be significantly improved. According to the technical scheme, the adaptive label merging device for the labeling machine is used in the folded labeling machine, two label-merging suction plates are symmetrically arranged on the two sides of a folded axis, a plurality of air holes are formed in the label-merging suction plates in a penetrating mode, the two label-merging suction plates are flexibly connectedthough wrapping leather, the wrapping leather is in an inverted-U shape, two L-shaped elastic pressing strips are symmetrically fixed to the inner wall of the wrapping leather along the two sides ofthe folded axis, the long edges of the L-shaped elastic pressing strips serve the compressing ends and are used for attaching the wrapping leather and the labels on the wrapping leather to the circumferences of the labeling objects in a fastened mode in the labeling process.

Description

technical field [0001] The invention relates to an adaptive labeling device for a labeling machine, which belongs to the technical field of double-fold labeling. Background technique [0002] The half-fold labeling machine is widely used for automatic labeling of cables, air pipes and water pipes. The half-fold labeling machine mainly consists of a feeding mechanism, a label delivery mechanism, a standard compliance mechanism and a bottom belt recovery mechanism. Among them, the standard conforming mechanism is the key component of the half-fold labeling machine, which determines the quality of the labeling. The unreasonable design of the standard conforming mechanism will cause quality defects such as air bubbles, misalignment, and loose bonding during the label pasting process. Therefore, the optimization of the standard conforming mechanism plays an important role in improving the performance of the half-fold labeling machine. [0003] The existing standard conforming me...

Problems solved by technology

However, in order to maintain the suction function, it is necessary to manually make ventilation holes on the film at the position of the air holes corresponding to the standard suction plate before pasting the film. The process is cumbersome, and the film will break after a period of time, affecting continuous production.

[0006] The length of the gap between the standard suction plates determines the diameter of the labeling object. When the circumference of the labeling object is smaller than the gap length, there will be a large gap during the wrapping process, which will affect the labeling quality; when the labeling object With a circumference greater than this gap, the label will not fully adhere to the surface

The distance between the above two standard-compliant suction plates cannot be adjusted adaptively. For different pipe diameters, it is necessary to manually adjust the gap between the standard-compliant suction plates, and the adjustment process is complicated.
