Laminator Operating Procedures

1. The sensing element of the temperature controller uses the thermocouple to detect the temperature. Due to the influence of the installation location and the surrounding air temperature and external airflow, the accuracy of the temperature measurement has a large error, which is indicated on the thermometer. The temperature is relative temperature, and the temperature should be selected according to the actual processing experience and the indicated value of the reference thermometer;

2. The site must be supervised when the machine is warmed up;

3. It is necessary to check whether the electrical facilities are in good condition before starting the machine;

4. The safety accessories such as protective covers and plates in the machine must be inspected 【 Film Lamination Machine 】before starting the machine to ensure that they are in good condition and are not allowed to be dismantled at will;

5. When the machine is running, it is forbidden to penetrate the fingers into the two rollers to avoid the hand. The temperature of the press roller of the machine is high. Do not touch the hand to prevent burns. When scrubbing the machine, start it at low speed. It should be scrubbed in the correct position to prevent two rolls. Inside the belt, the cloth in the hand;

6. When replacing the filter screen and adjusting the die and scraping the die, the gloves must be worn. If it is working, it is forbidden to wear gloves.

7. It is strictly forbidden to play bare-chested, shorts, skirts, dresses, etc., must wear tight clothes to work;

8. If there are plastic leakage materials, paper scraps, etc. above the composite roller, 【 Automatic Laminator 】 it should not be removed directly by hand, and should be drawn by means of plastic rods, small wooden sticks, etc.;

9. When cleaning the wrap film on the composite roll, it must be stopped;

10. When unloading, be sure to unload the air pressure system, separate the pressing roller from the rubber roller in time, and loosen the scraper and the pre-pressing roller to prevent the two rollers from being damaged by long-term deformation;

11. When the machine is repaired and inspected, the main power switch of the machine should be turned off. The electrical system of the machine should be well insulated to prevent moisture. When the machine is stopped, the power should be cut off to prevent accidents.

12. It is strictly forbidden to place any tools, devices and sundries on the machine. The working air gap of the rubberizing roller and the rubberizing roller is very small. When any hard object is pressed into the surface of the rubber roller, 【 Lamination Machine Manufacturer 】it will leave a crater on the rubber. Depression or crack. Lighter requires a longer period of natural elastic recovery, and the heavy one directly scraps the rubber roller;

13. Pay attention to electrical leakage and injury. Every employee should be aware of the method of urgently cutting off the main power supply. It is not clear that they are not allowed to work;

14. The machine used for new installation should be strengthened to lubricate the machine. Do not use the machine quickly during the running-in period of the machine drive.
　　

Pre-coated film lamination and Instant film lamination

The pre-coating film refers to a process in which a plastic film is sized and re-rolled before being combined with a paper printed product. It is firstly applied to the film by the pre-coated film processing factory according to the size of the specification. The glue is applied to the film for re-rolling, and then combined with the printed matter.

The pre-coated film was first used in 1989 and has been widely used in Europe and the United States. It entered Asia around 1996. At the same time as entering Asia, Europe and the United States have announced that it is forbidden to use the film as a pre-coating film. Due to the late use, all the countries in Asia except Japan have used pre-coated films, and other countries (such as China, South Korea, etc.) are in the state of pre-coating and film coating.【Roll Laminator Manufacturers】China has only used pre-coated films since 2000, and the market share of pre-coated films in China is still small. Precoat films have many advantages over instant coatings. If the pollution is reduced, there is no damage to the human body; the quality of the film will not be affected by the different properties of the paper or the color of the ink; the pre-coating film laminating machine is simpler to operate, and the processed image is better; the wrinkles are basically eliminated. , bubbles, shedding and other phenomena. Most notably, this is an environmentally friendly process, and the entire production process is harmless to the human body.

However, the promotion of pre-coated film in China is still relatively slow. Among them, the cost issue is a big influential factor, which determines the enthusiasm of investors for the pre-coating process. 【Reel to Reel Lamination Machine】In a recent survey, more than half of the respondents believe that pre-coated products are expensive in terms of price, because pre-coated products are printing consumables, and the cost of printing is a non-negligible problem for printers when selecting consumables. . In addition, due to the lack of paper and film separation technology in China, pre-coated films cannot be completely called an environmentally friendly process in China. In response to this situation, pre-coated products should reduce costs through mass production, so that market prices are getting closer to the needs of printers. At the same time, the research and development or introduction of the paper membrane separation technology should also attract the attention of relevant departments, in order to achieve environmentally friendly coating and rational development of the laminating process without being able to discard the laminating process.【Laminating Machine Supplier】It is a brand-new transfer technology that can cope with complex workpieces and is suitable for different materials. It also greatly increases the added value of products due to vivid patterns and vivid colors. This technology is a special chemical treatment film, after printing a certain color pattern, it is sent to the surface of the water, using water pressure to write the pattern evenly on the surface of the product, while the coated film is automatically dissolved, washed and baked. After drying, a layer of transparent protective coating is applied, and the product has a completely different visual effect.

Development trend of film lamination

The paper after the film lamination process is unrecoverable and becomes a white pollution, and toxic substances such as toluene and water are volatilized during the film coating process, which impairs people's health. Today, advocating "protecting the environment and protecting resources", the plastic film coating process has been eliminated in Europe and the United States, and European and American countries have even refused to import various packaging materials with plastic film. [ Thermal Lamination Machine ] Although there are water-based plastic film coating processes and hot-melt pre-coating film dry plastic compounding processes, the former still fails to solve the problem that the film printing waste cannot be degraded and cannot be recycled. The latter requires a large amount of heat in the production process and is discarded. The material needs to be separated in paper and plastic at 60 ° C, and the cost is high.



With the improvement of environmental awareness, new scientific and technological achievements will eliminate the old process products, so that the film process will undergo qualitative changes. "Non-toxic, harmless, green and environmentally friendly" naturally becomes an inevitable development trend of the film coating process. In addition, the glazing process is therefore optimistic. Glazing is a method of coating, spraying or printing to add a colorless transparent coating on the surface of the printed matter, that is, UV varnish. After calendering and drying, the gloss of the surface of the printed product is increased, and the stiffness is also improved. [ Thermal Laminator ] At the same time, the printed waste after glazing can be recycled or decomposed by itself, and does not pollute the environment. Therefore, glazing is a processing technology with great development potential, and it is possible to gradually occupy the plastic coating process market. Although the dilute machines used in oil glazing and alcohol glazing on the market are toluene and alcohol, respectively, which are harmful to the human body and unfavorable to environmental protection, water glazing has gradually become the mainstream of glazing process.[ Lamination Machine Manufacturer ] The water-based UV glazing process that has been developed so far is an ideal environmentally friendly glazing process and the development direction of glazing process in the future.
