Printing machine leading edge
Servo leading edge control, automatic size adjustment
leading edge double bellows
The front edge double bellows structure is used to make the cardboard adhere more smoothly to the paper, so that it can reach the printing department more smoothly and improve the printing quality. And it's a servo leading edge, with automatic adjustment of various sizes

Above is the doctor blade structure, which is matched with the ceramic roller; The following is the bellows, which is also responsible for conveying cardboard. The advantages of bellows conveying cardboard have just been explained. It also has a function in the printing group, which is to make the entire surface of the cardboard adhere to the bellows and print the entire cardboard in the left and right directions. This is something that common printing machines cannot achieve. From the cardboard in the right picture, it can be seen that the entire surface needs to be printed, so printing such cardboard requires a fully suction structure printing group, and each group structure requires a bellows structure, which is servo adjusted
Let me explain the structure of ceramics and doctor blade again.vacuum transfer printing machines are usually equipped with ceramics and doctor blade because ceramics and doctor blade are also used for better printing effects, just like luxury cars always have luxurious interiors
slotting unit
ordinary printing machines are generally equipped with two rows of wire pressing wheels, one set of pre pressing and one set of solid pressing. The vacuum transfer structure is generally equipped with three rows of wire pressing wheels, two sets of pre pressing and one set of solid pressing. The design of three rows of wire pressing wheels makes the cardboard more evenly stressed during the forming process. Increasing the number of pre pressing can effectively reduce the phenomenon of wire bursting, especially on thick cardboard or high weight materials. The compression wheel undergoes final shaping after two pre presses, ensuring clear indentation and accurate folding, improving the stability of subsequent die cutting and forming. The overall structural accuracy can be controlled within ± 0.5mm, significantly better than the ± 1mm error range of ordinary printing machines.
At the same time, the slotting group of the vacuum transfer structure will be equipped with independent drivers, which means that the drivers of the printing group and the slotting and die-cutting group are independent of each other. Because slotting and die-cutting are subject to vibration during operation, it will affect the printing effect of the printing group. In this way, independent drivers will not affect the printing effect.
Side discharge of waste belt
folding gluing unit
1) The folding belt adopts independent power and can adjust the scissor mouth of the cardboard at any differential speed.
2) Excellent spray adhesive system. Accurate to millimeters at any speed, the glue is sprayed onto the required adhesive positions on the cardboard box, minimizing cleaning and installation time during the production process and reducing waste
3) The printing department and the glue box department can achieve differential linkage, input the total width of the cardboard, and the glue box belt can automatically track
4) The straight out paper receiving section adopts variable frequency differential adjustment to adjust the paper box scissors mouth.
Circular fork paper delivery section
The cardboard first goes up, then falls down to collect the cardboard, and is then transported to the packaging section through a circulating fork structure. This structure has two main functions. The first is that the falling structure does not damage the printing surface, especially for high-quality cardboard. The second is that it will not cause cardboard jams for special-shaped cardboard with die-cutting or perforated cardboard
