The vibration of the laminator mechanism is one of the important factors that affect the accuracy of the laminating machine. With the rapid development of the printing and packaging industry at home and abroad, all kinds of printing equipment and post-press processing equipment have developed by leaps and bounds. In the post-press processing technology, the laminating technology is widely used. With the continuous improvement of customers' requirements for laminating technology, a high-precision laminating machine is urgently needed.
        In the existing domestic laminating equipment, it is difficult to improve the accuracy as the main reason restricting its development. In the post-press processing process, the laminating technology is widely used, and the market urgently needs high-speed, high-precision laminating machines. On the basis of analysis and testing technology principles, based on the signal test analysis system software, a more complete laminator vibration test program was selected, and the vibration of the main mechanism components of the laminator was tested. The results show that the vibration at the wallboard is the largest, followed by the front gauge shaft, the side gauge shaft moves more smoothly, and the vibration is the smallest.
        Main functions and features of automatic laminating machine
        Automatic laminating machine is a kind of special equipment used for paper, board and laminating film. Next, let me talk about the main functions and features of the automatic laminating machine.
        1. Automatic paper feeder: The precise design of the feeder feeder enables smooth feeding of thick and thin paper. It adopts a stepless speed change device and is equipped with automatic edge control to adapt to different paper feeds. Sophisticated wind head, it is very convenient to adjust the relative position of the wind head and the paper stack during operation. The unique non-stop paper feed device, which is equipped with an auxiliary table, can replenish the paper while feeding it to ensure continuous production.
        2. Powder removal device (optional combination): adopts two-stage powder removal structure of powder sweeping and pressing powder, the paper passes through the conveyor belt by the brush roller and the brush sweeping powder, so that the dust on the surface is sucked away by the suction fan, and then passes through the electric heating After the pressing roller is rolled, it effectively removes the dust attached to the paper during the printing; the tightly arranged design of the conveyor belt combined with the high-efficiency suction prevents the paper from being out of position or misaligned, so that the paper can be accurately delivered to the nip of the host.
        3. The hard chromium composite roller of the fully automatic laminating machine is equipped with an electric heating system and an automatic temperature control device to make the temperature distribution even. The design of the enlarged composite roller increases the pressing surface: the diameter of the electric heating roller is 420mm, and the inner wall of the roller core is round, so that the roller is not biased and the heating surface is uniform; the diameter of the pressing rubber roller is 360 mm, which ensures smooth OPP film pressing Stable operation. The hand pressure hydraulic cylinder controls the compound pressure, which can balance the pressure of the left and right rollers. The high-precision hard chrome plated mirror heating roller cooperates with the high-performance pressing rubber roller to perfectly realize the hot laminating process.
        4. The coating oil head is controlled by imported frequency converter. The glue roller is subjected to high-precision grinding and special balancing treatment on the inner wall to more effectively maintain the stability of the coating amount. The coating and metering hard chrome rollers manufactured by high precision The barrel ensures uniform coating amount and achieves precise coating effect. The laminator is equipped with two sets of oil pumps and stainless steel oil tanks at the same time, which is suitable for the use of water-based and oil-based glue. It adopts DC motor pressure film coating device, which is stable, fast and easy to operate.
        5. The film unwinding shaft adopts magnetic powder brake to maintain stable tension, and the unique pneumatic film stretching device ensures the tightness of the film during film pressing and film lifting, which effectively prevents the film rolling failure.
        6. Automatic cutting device: The cutting length can be set freely according to the paper size, and the speed can be freely controlled. The linkage operation system of the unit, with the speed of the host, automatically increases and decreases, the operation is simple, the labor cost is saved, and the labor intensity of the operator is reduced. Knife disc rotating blade design, 4 sets of blades of rotary knife seat, can be fine-tuned and controlled, easy to operate; when adjusting, cooperate with the pressure roller to interact. Equipped with a reverse paper roller, it can cut thin paper, and paper with more than 128 grams can be automatically cut online; equipped with an automatic winding device, which can be rolled into a roll for paper with poor quality and hardness.
        7. The drying system adopts special horizontal drying box design and manual constant temperature control system (convenient operation, fast heating speed, and effective saving of auxiliary time from 30 ° to 90 ° in only about 15 minutes), this design can make OPP The film runs stably and dry without causing the film to shift or shrink. It is suitable for the drying system of water-based glue. It has high heat and wide distribution, completely distributing the heat energy evenly on the OPP glue film, prompting the glue to dry quickly, and the reaction speed is fast.
        8. The advanced circuit adopts FATEK original PLC programming control, and the whole machine is mechatronically controlled. The touch screen can automatically adjust the overlap size without manual operation, reducing the error of paper overlap. The man-machine interface displays speed, mechanical working status, and fault prompts to achieve humanized operation; the motor adopts frequency conversion control, which is stable, energy-saving, safe and reliable.

        9. Automatic paper take-up machine (optional combination): pneumatic double-sided paper aligning device, with paper counter; conveying table with vacuum suction air belt; paper thin paper guide device; chain suspended hanging board paper table, photoelectric induction automatic Descent; the paper collection table is equipped with an auxiliary carrier, which can collect paper without stopping the machine. (If there is no optional automatic take-up machine, add a counter before receiving the cardboard to measure the alarm.)
