[0033] In this embodiment, the slow pressure mechanism on the packaging and printing production line, the slow pressure mechanism through the column 1, beam 2, pneumatic push rod 5, etc., forms a stable pressure covering system, the fixed connection of the column 1 and the beam 2 ensures the stability of the mechanism, and the telescopic end of the pneumatic push rod 5 provides flexible pressure covering power.

[0035] The working principle of the above embodiment is as follows:

[0036] When the packaging and printing products are conveyed to the pressure covering seat 18, the slow pressure mechanism is started by the signal of the production line or control system. The pneumatic push rod 5 starts to extend after receiving the signal, pushing the moving plate 6 to move downward. The moving plate 6 drives the spring 10 and the second limiting column 9 fixedly connected thereto to move downward, and the second limiting column 9 slides in the first positioning hole 7 to ensure the stable movement of the moving plate 6 in the vertical direction. As the moving plate 6 descends, the spring 10 begins to be compressed, absorbing part of the vibration in the pressure covering process. When the pressure covering head 12 and the buffer pad 13 thereon contact the packaging and printing products, the spring 10 and the air bag 11 are further compressed, the air pump 14 is started or adjusted to output, and compressed air is filled into the air bag 11 through the connecting pipe 19 to make the air bag 11 expand and provide additional buffering effect. The buffer pad 13 ensures the gentleness of the contact with the printed matter, avoiding damage. When the predetermined pressure covering time or pressure is reached, the pneumatic push rod 5 begins to retract, driving the moving plate 6, the lower pressing plate 8 and other components to rise to the initial position. The air pump 14 stops working, and the air pressure in the air bag 11 is gradually released. The packaging and printing products are completed by pressure covering and conveyed to the next process by the production line.
