Automatic coating and labeling machine with constant tension mechanism

Abstract

The invention discloses an automatic coating and labeling machine with a constant tension mechanism. The automatic coating and labeling machine comprises a frame plate box, a pasting mechanism and a discharging mechanism, the pasting mechanism and the discharging mechanism are arranged on the upper side and the lower side of the interior of the frame plate box respectively, the discharging mechanism comprises two sets of fixing boxes and a plurality of sets of transmission bearing components, and the invention relates to the technical field of laser holographic anti-counterfeiting marks. According to the automatic coating and labeling machine with the constant tension mechanism, a transmission roller is pushed by an arc-shaped notch, so that the transmission roller and a linear notch slide and contract, a columnar product is clamped through a rubber roller sleeve, a rotating disc drives an auxiliary hinge rod to push a sliding plate connected with an auxiliary connecting rod to move downwards, and thus a driving motor drives a driving wheel to move downwards; and the driving wheel, a positioning wheel and two sets of driven wheels are all kept in a tight state with a transmission belt all the time, the driving wheel is driven by the driving motor to rotate, the rubber roller sleeve drives the product to rotate, the structure is simple, labeling treatment of the columnar product is facilitated, the automation degree is high, and the labeling efficiency and the labeling quality are greatly improved.

AI Technical Summary

Benefits of technology

This patented device has several technical featments: 1) an auto-coating/labelging machine with a steady tensional movement system where multiple pairs of conveyors can be moved together without interferring; 2) a variable length linkage connection between the machines' components such as fixing frames or drums, which allows them to slide freely when changing directions while maintaining their alignment. 3) a buffer hoop bar attached to each chain module, allowing the labels to pass over slip rings and come into close proximity before being transferred onto objects like rods. 4) a special design for these devices makes sure they have consistency in terms of size and shape of the items being processed (such as tubular goods).

Problems solved by technology

This patented describes two main problem areas where current labeling methods have limitations - they can result in poorly marked products when applied manually onto packages without properly fixing them during printing processes; while others require expensive automated systems like those currently available at this time.
