The laminating machine is divided into two categories according to different equipments and processes, one is "coated film" and the other is "pre-coated film"; there are two kinds of film and sub film.
        Instant-coated film is a process that uses instant-coated film machine to immediately stick film with glue to carry out paper-plastic compounding. It mainly consists of a coating film processing plant or a processing workshop, where the roll plastic film is coated with an adhesive as required, dried (slightly) compounded, and after pressure, the paper film is adhered together to form a coated product. That is, there are two types of film coating equipment: automatic and semi-automatic. The basic working principles are the same; the process flow mainly includes unwinding → sizing and coating → drying → compounding → slitting → finished product accumulation.
        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. So what should we do before the lamination process?
        Inspection work before laminating machine:
        1. Check before laminating machine to confirm whether the machine is in a safe state.
        2. Film transport adjustment to make the film tension even to adapt to the film transport tension.
        3. Check whether the gap between the glue roller and the glue is parallel.
        4. Check the temperature of the heating roller to avoid inaccurate thermometer.
        5. The pressure that the pressure gauge must reach, otherwise the pressure will affect the product.
        6. Clean the sundries on the rubber roller, so as not to cause waste in the finished product.

        After completing the preparation work, close the main power switch, turn on the heating cylinder and the motor, then turn on the oil pump, adjust the flow rate of the laminating glue, and adjust the parallelism between the rollers. Adjust the measurement position of the paper on the feeding table, apply the film-coated glue, and turn on the drying tunnel for heating. After testing several sheets of film, adjust the heating temperature, pressure and air intake of the heating roller again until the effect is good, and then start normal work.
