Anti-counterfeit label making robot assembly line based on expansion and stretching

Abstract

The invention discloses an anti-counterfeit label making robot assembly line based on expansion and stretching. The anti-counterfeit label making robot assembly line based on expansion and stretchingcomprises a bottom plate, an expansion mandrel, an inner expansion and stretching mechanism as well as a stretching film roll, a primary material pulling mechanism, a particle attaching groove, a secondary material pulling mechanism, an outer expansion and stretching mechanism and a film layer slitting mechanism; the expansion core shaft comprises a feeding part, a material absorbing bending part,a conical expansion part and a forming slitting part which are connected sequentially; the feeding part faces towards the stretching film roll and passes through the primary material pulling mechanism; the material absorbing bending part stretches into the particle attaching groove; the secondary material pulling mechanism is connected between the material absorbing bending part and the conical expansion part; the inner expansion and stretching mechanism is arranged in the forming slitting part; left and right side regions of a tubular plastic stretching film of the stretching film roll are coated with adhesive layers respectively; upper and lower side regions of the tubular plastic stretching film of the stretching film roll are stretching parts without viscosity; and the anti-counterfeit label making robot assembly line based on expansion and stretching can achieve the aim of eliminating the lap joint phenomenon of the particles, can improve the identifiability of the anti-counterfeit label and has more excellent anti-counterfeit effect.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting technology, in particular to a robot assembly line for making anti-counterfeiting labels based on expansion and stretching. Background technique [0002] The production method of the existing anti-counterfeiting labels is usually to sprinkle anti-counterfeiting particles directly on the material coated with an adhesive layer, which will lead to the phenomenon that the anti-counterfeiting particles overlap together, and the overlapping between the particles It will seriously affect the recognizability of the anti-counterfeiting label, and then fail to achieve the purpose of distinguishing the authenticity. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings, and provide a robot assembly line for making anti-counterfeit labels based on expansion and stretching. [0004] To achieve the above object, the specific scheme of the pr...
