Anti-counterfeiting label outer surface laminating machine

Abstract

The invention relates to an anti-counterfeiting label outer surface laminating machine. The laminating machine comprises a base, wherein the left end of the base is provided with a power mechanism, the top surface of the base is provided with an upper pressing roller and a lower pressing roller through a driving shaft, a gap is left between the upper pressing roller and the lower pressing roller to ensure the passage of an anti-counterfeiting label and a membrane, the driving shaft is connected with the power mechanism by a coupling, a driven shaft is arranged above the base by a left side plate and a right side plate, the driven shaft is connected with the power mechanism, a membrane roll is arranged on the periphery of the driven shaft, and the top surface of the base is provided with apre-heating mechanism through two mounting mechanisms. According to the provided anti-counterfeiting label outer surface laminating machine, a gap is left between pre-heating rollers and the membraneroll, the membrane roll temperature is reduced, the inner structure of the membrane is protected, the service life of the membrane is prolonged, the membrane roll is uniformly pre-heated, the pre-heating effect is good, the laminating quality is improved, the membrane is prevented from falling off, the pre-heating hot air flow impact force is small, and the risk of breaking the membrane is reduced.

Description

technical field [0001] The invention relates to the technical field of laminating machines, in particular to a laminating machine for the outer surface of an anti-counterfeit label. Background technique [0002] Anti-counterfeiting label is a kind of label with anti-counterfeiting function. The anti-counterfeiting features and identification methods of anti-counterfeiting labels are the soul of anti-counterfeiting labels. preventive measures. In daily life, people can identify the authenticity of products through the anti-counterfeiting code of the anti-counterfeiting label. In order to protect the anti-counterfeiting code from being scratched, it is necessary to cover a protective film on the surface of the anti-counterfeiting label, which requires the use of a laminating machine. [0003] The laminating machine can be divided into two categories: the coating type laminating machine and the pre-coating type laminating machine. It is a special equipment for paper and board...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a laminating machine for the outer surface of an anti-counterfeit label, which can solve the problem that the above-mentioned middle preheating roller is close to the film roll, and the temperature of the film roll is too high, which will damage the internal structure of the film and reduce the service life of the film; The preheating of the film roll is uneven and the preheating effect is poor, resulting in poor quality of the film and the film is easy to fall off. In addition, the hot air flow preheated by the film laminating machine has a large impact force and there is a risk of damaging the film.
