Concerning the maintenance of the vacuum laminator, there is a variety of opinions, and we will briefly introduce the maintenance methods. Any machine equipment needs to be regularly inspected, especially the parts of the vacuum laminator. We need to regularly check whether there is damage. If any damage is found It is necessary to replace the new parts immediately; it is also very important for the cleaning of the machine. It is not allowed to be surrounded by people during the operation of the machine, and it is not possible to put debris on the equipment. This is also to prevent the machine from automatically returning to the heating hood. Human approach.
        The last point is to operate in accordance with the instruction manual, and prohibit incorrect operation, so as not to cause greater losses to the machine.
        For personal safety and product safety, everyone should follow the correct method and procedures when using any product to avoid unnecessary accidents. The company here explains the main points of the correct operation of the vacuum laminator.
        First of all, we must ensure that the rotating parts of the pressing device are not damaged, and we must clean the work table frequently without dust, and prepare necessary items, such as product pads. To adjust the temperature of the film from time to time, make sure that the pressing frame is locked when opening the heating hood. There are no objects on or around the guide rails, and the hands of the personnel must be away. It is strictly forbidden to stand around when the laminator is working. If the machine makes an abnormal sound, it should be turned off immediately. The protective items such as safety covers cannot be removed at will. Turn off the power after the final work.

        The pre-coating laminating machine is a special equipment that combines printed materials with pre-coated plastics. Compared with the instant coating laminator, the biggest feature is that there is no sizing and drying parts, so this type of laminator is compact in structure, small in size, low in cost, easy to operate, and has good product quality stability.
        The pre-coating laminating machine consists of four main parts: pre-coating plastic film unwinding, automatic input of printed matter, hot-press area compounding, and automatic rewinding, as well as mechanical transmission, pre-coating plastic film flattening, vertical and horizontal slitting, and computer control system And other auxiliary devices.
        1. The automatic conveying mechanism of the printed matter input part can ensure that the printed matter does not overlap during the transmission and enter the composite part at an equal distance. It is generally controlled by pneumatic or friction methods. The conveyance is accurate and high precision. It can also be used when the printed product with a small composite format is small Meet the above requirements.
        2. The composite part includes a composite roller group and a calender roller group. The composite roller group is composed of silicon rubber heating pressure roller pressure roller. The hot pressure roller is a hollow roller, which is equipped with a heating device inside, and the surface is forged with hard chrome, and is polished and refined. The temperature of the hot roller is tracked by the sensor and corrected by the computer at any time. The compound pressure is adjusted by an eccentric cam mechanism. Stepless adjustment. The calender roller group is basically the same as the composite roller group, that is, it is composed of a chrome-plated pressure roller and a silicone pressure roller, but without a heating device. The main function of the calender roller group is: after the pre-coated plastic film and the printed matter are compounded by the composite roller group, the surface brightness is not high. After the secondary extrusion of the calender roller group, the surface brightness and adhesion strength are greatly improved.
        3. Transmission system The transmission system is driven by a high-power motor controlled by a computer. After one-stage gear reduction, it is driven by a three-stage chain to drive the movement of the paper feed mechanism and the rotation of the silicone pressure roller of the composite part and the calendering mechanism. The pressure roller set maintains a suitable working pressure under the action of steplessly adjusted pressure.
        4. Computer control system The computer control system uses a microprocessor. The hardware configuration consists of a main board, digital key board, optical isolation board, power board, stepper motor power driver board, etc.

        Problems and solutions in the laminating process of the laminating machine.
        One: crumpled paper
        1. The film pulling force produces vertical folds of folded folds. Adjust the film tightness;
        2. The film itself is loose and uneven. Adjust the film transmission stick;
        3. The pressure is too high, the temperature is too high, horizontal wrinkle, adjust the pressure, and temperature;
        4. The rubber pressure stick is deformed, disassemble the pressure stick, and regrind;
        5. The paper is damp, keep the working environment and paper products dry or use drying in laminating;
        Two: wrinkled film
        1. If the temperature is too high, reduce the temperature appropriately and reduce the pressure to adjust the temperature required for various membranes;
        2. Adjust the imbalance of the film feeding stick, adjust the balance of the film feeding stick;
        3. The film stacking time is too long, replace the film;
        4. The film tension is too large or too small, adjust the film tightness;
        Three: There are snowflakes on the product
        1. Too much powder sprayed on the printed matter, sweep away the powder sprayed on the printed matter before laminating;
        2. The pressure of the pressure roller is inappropriate, the solution is to adjust the pressure of the pressure roller correctly;
        3. If the temperature is too low, adjust to an appropriate temperature;
        Four: bubbles appear
        The pre-coating laminating machine consists of four main parts: pre-coating plastic film unwinding, automatic input of printed matter, hot-press area compounding, and automatic rewinding, as well as mechanical transmission, pre-coating plastic film flattening, vertical and horizontal slitting, and computer control system And other auxiliary devices. The automatic conveying mechanism can ensure that the printed products do not overlap and enter the composite part at an equal distance during transmission. Generally, pneumatic or friction methods are used to achieve control. The conveying is accurate and high precision. The same requirements can also be met when printed products with small composite width.

        The laminator has high requirements for temperature control. If the temperature is too high and the heating time is too long, the film quality will decrease without heating. If the drying temperature is too high, the adhesive surface will form a skin, which will cause blistering of the film. Excessive thermal stress will also cause the film to lose its elasticity, resulting in reduced performance and easy tearing.
        There are three methods of heat dissipation in physics: conduction, convection and radiation. The first two have been excluded. That can only be solved by thermal radiation. Radiation heat dissipation can not be affected by the temperature of the medium around the object. As long as the temperature of the object exceeds zero degrees, the object must go out Radiating heat, but the heat radiation amount of the object itself is very small, which can not solve the object's heat dissipation and cooling, only increase the heat radiation amount of the object to reduce the temperature of the object, so apply a layer of heat dissipation coating on the surface of the object Thermal paint greatly enhances the heat radiation of objects to reduce the temperature of objects.
        The heat dissipation coating improves the heat exchange in the form of infrared radiation, and the heat dissipation is not affected by the surrounding medium. The heat dissipation of the paint can be used in a vacuum environment. The radiation heat dissipation cooling coating can improve the heat exchange and also have good self-cleaning properties. Insulation, corrosion resistance, water resistance, acid and alkali resistance, and convenient construction.
