The laminating machine is to apply the adhesive to the plastic film and combine it with the printed matter using paper as the substrate, pressurized by the rubber roller and the heating roller, and form a product of paper and plastic. Due to the thin and transparent plastic film on the surface of the printed product, the surface is smoother and brighter, which not only improves the gloss and fastness of the printed product, but also extends the service life of the printed product. At the same time, the plastic film is waterproof and Protection against dirt, abrasion, folds, and chemical corrosion.
Detailed description of laminating machine:
1. The base, wall plate, etc. are made of cast iron, never deformed, to ensure that the accuracy will not be affected during the use and repair and replacement of parts.
2. The glue roller and glue roller are manufactured with precision, and the concentricity error of the roller surface is controlled within 0.01mm to ensure even glue application and save glue consumption.
3. The hot composite steel roller is processed by mirror surface treatment, and the finished film is excellent.
4. Electronic automatic constant temperature device.
5. Unique design of hydraulic system, precise and stable.
The development of the water-based laminating machine has greatly promoted the application of the water-based laminating process. The water-based wet laminating film is favored by customers because of its high strength, high grade, easy recycling, and no pollution. When the water-based coating process was just promoted, because the customer didn't know much about the process, he had more concerns and was afraid of problems. In view of this, he had done a lot of tests for the customer in advance, for example: to test the temperature resistance of the printed product after water-based coating , Moisture resistance, oil resistance and other properties, the relevant coating test was done in the early stage of the machine, regardless of temperature resistance, humidity resistance, oil resistance, can meet the requirements of the coating product.
The water-based laminating machine is an effective method for processing the surface of the printed matter to improve the gloss and strength of the printed matter, enhance the aesthetic effect, temperature resistance, water resistance and wear resistance, improve the quality of the printed matter and the value of the commodity, so the quality of the film is weighed , Also need to examine the brightness, strength, adhesion and other aspects of the film.
The laminating process of laminating machine refers to the whole process of laminating pictures and photos, including film selection, film making, and cutting. Mainly used for post-production of advertising pictures and wedding photos. The pictures covered with film have high anti-corrosion, waterproof, dustproof, anti-wrinkle and anti-ultraviolet erosion performance, which can produce strong three-dimensional sense and artistic appeal. The cold laminating machine is the main equipment to complete the laminating, and it is also the necessary supporting equipment for the computer inkjet machine and electrostatic photo machine. The commonly used equipments for lamination include manual cold laminator, electric cold laminator, self-exposed film cold laminator and automatic cold and hot laminator. There are also transfer equipment.
1. Overlay the protective film on the picture to improve the strength of the picture and the wear resistance of the surface.
2. Isolate the picture from the outside air to prevent deformation and cracking caused by corrosion, humidity, and drying of corrosive gases in the atmosphere, fading and discoloration caused by rain scouring and ultraviolet radiation, and keep the bright color of the picture screen enduring, Extend the life of picture display.
3. Paste the picture on the display board or fabric to make a hanging advertising picture.
4. Press a special mask or sheet on the picture to form a picture with special artistic effects such as bright light, matt, oil painting, virtual and three-dimensional.
Post-press laminating or post-printing refers to the use of a laminating machine to cover the surface of the printed product with a layer of 0.012-0.020 mm thick transparent plastic film to form a paper-plastic integration product processing technology. The laminating machine is the equipment used to complete the laminating process. Generally speaking, it can be divided into two types: instant coating film and pre-coating film according to the process used, and two kinds of bright film and matte film according to the different film materials. The main problems affecting the laminating process: affecting the health of the operators, there is a potential fire hazard; the paper and film materials after the lamination are difficult to recycle, wasting resources.
The temperature control of the laminating process of the pre-coating and pre-coating machine also affects and determines the hot-melt adhesive used for laminating to solve the changes when heated, and the resistance to the new heat. Therefore, strict temperature control is the primary key to the pre-coating film machine. According to the practical process, it is found that the quality of the pre-coating laminator is mainly affected by three factors: temperature, pressure, and speed. Therefore, the relationship between the three is correctly handled to ensure the quality of the pre-coating laminator and to the production process of the next process. The impact is very important. The paper-plastic coating will be the comprehensive result of the physical function of thermocompression. Temperature, pressure, and speed are the three basic factors for achieving this physical comprehensive effect. Correctly handling the relationship between the three is the process operation. The key to technology.
Temperature is the first key to laminating. The adhesive used for pre-coating is hot-melt adhesive. Temperature determines the melting state of hot-melt adhesive, the leveling performance of hot-melt adhesive, and the molecules of hot-melt adhesive to the film. , The printing ink layer, the paper substrate and other three molecules of the diffusion capacity of molecules, but also determines the crystallinity of the hot melt adhesive, only the correct control of the temperature of the working area can make the pre-coated film on the film of solid hot melt adhesive The layer is completely melted into a viscous state, with suitable fluidity to achieve wetting and bonding to the surface of the printed matter, and at the same time to ensure immediate solidification after compounding, so that the laminated film product has a smooth appearance, bright enough, and the adhesive layer is melted well without folding mark. And can peel the ink.
The hot film of the hot laminating machine relies on the intimate combination with the surface of the paper and is packaged in a roll package. The hot film used by the hot laminator is thinner and softer. The paper after the hot film is not as hard as the plastic film. The paper is still flexible and can be curled. There is no need to worry about over-plastic curling when using a laminator, but cold laminators and single-sided hot laminators are prone to warp for thin paper lamination (unless a professional, high-cost anti-roll single-sided is used Hot film), if the paper is curled and then unfolded after cold lamination, bubbles and wrinkles may appear. Single-sided cold lamination is also easy to curl the paper, and the laminating curling is also used with the functions of temperature and speed adjustment of the hot laminator. There are relationships.
On the one hand, in the field of membranes, seeking high-performance membranes in a wide range of industrial fields, the development of new raw material resins, the development of processing technologies such as compounding and multi-layering are currently prevalent. However, global issues such as energy saving, from the perspective of the environment, the use of membranes in parallel with solvent-free membrane technology and energy-saving manufacturing methods in terms of electron beam irradiation. Film-coated steel sheets are aimed at the industrial field, and are related to IT and optics, automotive, and building decoration, and other fields, and are widely used. Examples of specific contents are film production method, physical properties, durability, other characteristics, etc.
