In order to achieve the purpose, the invention provides the following technical scheme that the packaging and printing device combination structure comprises a unreeling part, a printing part, a drying part and a reeling part which are sequentially arranged, wherein the printing part comprises a printing box and a printing part arranged in the printing box, a feeding hole and a discharging hole are respectively formed in two sides of the printing box, which are close to the unreeling part and the drying part, the top of the printing box is provided with an upper partition plate, the printing box is divided into a dedusting cavity close to the unreeling part and a printing cavity close to the drying part by the upper partition plate, and the printing part is arranged in the printing cavity; the top in dust removal chamber is equipped with a honeycomb duct, and the intercommunication has the inlet tube on the honeycomb duct, and the intercommunication has a plurality of atomizer on the bottom surface of honeycomb duct, and the bottom of going up the baffle is rotated and is connected with the dust removal roller, and the outside of dust removal roller is provided with the cotton flannel.

The technical principle of the technical scheme is as follows:

the film to be printed enters a dust removal cavity of the printing box from the unreeling part, water is introduced into the dust removal cavity through the atomizing nozzle, static electricity on the film is eliminated by the water, and the film is prevented from continuously adsorbing dust; and along with the removal of film, the film can contact with the dusting roller, clears up the film surface through the cotton flannel on the dusting roller, promotes the cleanliness factor on film surface. When the film enters the printing cavity, the amount of dust adhered to the surface is small, and further the influence on the printing effect is small. After the film printing is finished, the film is led out from the discharge port, enters the drying part to dry the ink, and is wound by the winding part.

The beneficial effects of the technical scheme are as follows:

1. according to the technical scheme, the printing box is divided into the dust removal cavity and the printing cavity by the upper partition plate, so that the dust of the film can be removed before printing, the cleanliness of the surface of the film is improved, the printing effect is improved, and the defective rate of printing is reduced;

2. by spraying the liquid above the film, the static electricity on the surface of the film can be eliminated, so that the amount of dust adhered to the film is reduced, and the liquid can also wash and clean the dust on the surface of the film;

3. the dust removing roller is arranged at the bottom of the upper partition plate, so that the lint on the dust removing roller can be utilized to generate relative friction with the thin film in the thin film transmission process, and water stains and dust on the surface of the thin film can be cleaned;

4. set up the baffle, can separate dust removal chamber and printing chamber, the water smoke receives blockking of film moreover, can block water smoke and get into the printing chamber, and then the influence that the film printing that reduces caused promotes the effect of printing.

To sum up, this technical scheme is separated for the dust removal chamber and is printed the chamber through the printing case with printing portion, can clear up dust and impurity including the surface adhesion before the printing to reduce the printing back because of the dust drops the condition appearance that appears printing blank point, promote the quality of printing, reduce the defective percentage.

In the whole development process, the inventor conducts multiple tests and searches for reasons, and finds out that the reasons for the occurrence of printing blank spots mainly comprise three reasons, wherein one of the three reasons is that a film is wrinkled or offset in the conveying process; secondly, ink of the printing part is unevenly smeared; thirdly, more dust is adhered to the film, so that the ink is isolated from the film, and the ink falls along with the dust. The inventor carries out gradual research and treatment on the three reasons, and the technical scheme is mainly developed and solved aiming at the third reason.

In the course of research and development, the applicant has conducted a great deal of market research and technical search, and found that the most currently used way is negative pressure adsorption, so the inventor has conducted continuous research and development on the basis of the prior art, and suction is performed by arranging negative pressure devices above and below the film. However, in the specific experimental process, the suction gas can generate a pulling force on the film, so that the film is easily damaged; and the position of the film is deviated due to a pulling force given to the film by the suction, so that the film is in a deviated state when entering the printing part, and the printing deviation can occur. And through specific use, the effect of adsorbing and removing dust by using the negative pressure device is limited, and the film can continuously adsorb dust after moving out of the negative pressure part. After many times of experiments, the inventor has obtained the reason, because the film is at the in-process of production and transportation, the surface produces static, and static can adsorb the dust, even removed dust, still can continue the adhesion dust, leads to whole effect not good enough.

In this regard, the inventors used another method of blowing air to the surface of the film by an ion blower to remove static electricity from the film and blowing up dust so that the dust is detached from the film. However, this method also causes dust to be diffused in the whole space, a negative pressure device needs to be additionally arranged to suck air, and the air sucked can affect the air blown out by the ion blower, so that the whole dust removal effect is affected. And the ion blower blows on the surface of the film, so that the film is impacted and damaged.

In the whole development process, the research and development of the inventor meet the bottleneck, but at this moment, the inventor suddenly thinks that the very effective effect of removing static electricity is water, but through technical search, the field usually does not use water to remove static electricity, so the water can be adhered to the surface of the film to influence the subsequent printing effect. But the inventor sets up and improves the structure, after utilizing water to eliminate static, carries out the drying to the surface of film, and water can also subside the dust simultaneously, avoids the dust to diffuse in the air, causes the condition of follow-up step adhesion dust to appear.
