[0030] Waste collecting guiding roller 701, waste collecting shaft 702, peeling roller group 703.

[0031] This embodiment is an explanation and / or description made according to the intuitive expression in the drawings, and the protection scope of the present invention is not limited to the situations listed in this embodiment. For the intermittent and / or full-rotation multi-functional combined digital printing device, see the attached Figure 1 , which is composed of components such as a feeding unit 1, a flexographic printing and cold stamping lamination unit 2, an external industrial control computer 3, multiple groups of digital printing units 4, a flexographic varnishing / laminating unit 5, an intermittent die-cutting unit 6, and a winding and waste collecting unit 7 from left to right in sequence.

[0032] The feeding unit 1 is placed at the leftmost side of this device. The material wound on the feeding shaft 101 in the feeding unit 1 reaches the feeding roller group 219 in the intermittent / full-rotation printing unit and cold stamping unit after passing through multiple feeding guiding rollers 102, a corona treatment device 103, and a deviation rectifying device 104.

[0033] The unwinding shaft holds the printing material and keeps the material tension stable. After passing through multiple guide rollers, the material unfolds smoothly. After passing through the corona treatment equipment and the deviation rectifying device, the ink affinity of the material surface increases and is suitable for printing, and the paper edge is in a straight line state and is stably conveyed to the next station.

[0034] In the intermittent / full-rotation flexographic printing and cold stamping lamination unit, the pulling roller part is placed at the lower part, and the feeding roller group in the pulling roller part On one side of 219, there is a swing rod group , the swing rod group On one side of there is a pulling roller group 218, above the swing rod group there is a flexographic printing part. On one side of the flexographic printing part, there is a cold stamping lamination roller group 211 in the cold stamping lamination part. The flexographic printing part is provided with a bottom roller 202, a plate roller 201, a scraper 204, an ink tank 205, etc. Above the bottom roller 202, there is a plate roller 201. A flexible plate is sleeved on the outer circumferential surface of the plate roller 201. The flexible plate is a whole-circle structure or a partial structure.

[0035] The first swing rod servo motor 206 can rotate clockwise and counterclockwise alternately, or it can also not rotate. When the first swing rod servo motor 206 rotates clockwise and counterclockwise alternately, the flexographic printing part is in an intermittent working mode, and the flexible plate only adheres to a part of the outer circle of the plate roller; when the first swing rod servo motor 206 does not rotate, the flexographic printing part is in a full-rotation working mode, and the flexible plate adheres to the whole circle of the plate roller.

[0036] Below the cold stamping lamination roller 214, there is a first UV lamp 212. The material passes through the feeding roller group 219, passes through the swing rod roller group , enters the cold stamping lamination roller group 211, and then enters the swing rod group , and then enters the pulling roller group 218; the servo motor in the swing rod group adopts two working modes of rotating or not rotating; the material passing through the pulling roller group 218 enters the digital printing unit. The first color mark electric eye 401 in the digital printing unit locates the color mark part of the material, and then sends a positioning instruction to the digital printing unit for printing at the specified part. After that, it reaches the cold water roller 403, is cured by the second UV lamp 404, and then enters the pulling roller group II 405.

[0037] The feeding roller group 219 consists of two upper and lower rollers. After the material passes smoothly through the gap between the two upper and lower rollers, it enters the space between the plate cylinder 201 and the bottom roller 202 through the first guide roller 208, the second guide roller 221, and the flexographic guide roller 213 and can pass through smoothly. A anilox roller 203 is arranged on the left side of the plate cylinder 201. A doctor blade 204 is arranged on the left side of the anilox roller, and an ink sump 204 is arranged below the doctor blade 204. The ink sump 204 is placed above the material. After the material is printed, it is bonded together with the cold stamping film material released from the cold stamping frame material shaft 215 through the gap between the two rollers of the cold stamping laminating roller group 211; after being irradiated and cured by the first VU lamp 212, it then passes through the third guide roller 222, the fourth guide roller 223 and other guide rollers and the pulling roller group and then enters the space of the two roller groups in 218 and passes through smoothly. Among them, the waste material is wound on the cold stamping waste shaft 216 through the waste collection guide roller 217.

[0038] When the flexographic printing department is printing, a color block will be printed on the blank edge of the material as a color mark for positioning in the subsequent processes. When the flexographic printing department is in the full-rotation working mode, the cold stamping laminating department can work simultaneously. The printed material reaches the cold stamping laminating roller group 211, and the cold stamping film on the cold stamping frame material shaft 215 also reaches the cold stamping laminating roller group 211 after being flattened by multiple guide rollers. The two materials are pasted together here and then go down and are cured by the first UV lamp 212. At the pulling roller group 218, the two materials are peeled off. The cold stamping film goes upward through the waste collection guide roller 217 and is wound on the cold stamping waste shaft 216; the printed material after cold stamping continues to go downward and enters multiple digital printing units for digital printing.

[0039] When the flexographic printing department is in the full-rotation working mode, the cold stamping laminating department can stop working (mostly controlled by a pneumatic clutch device to make one moving roller leave the other fixed roller). When the flexographic printing department is in the intermittent working mode, the cold stamping laminating department cannot work, and the two rollers in the cold stamping laminating roller group 211 are not pressure-bonded. The printed material passes downward through the gap between the two rollers of the cold stamping laminating roller group 211, is cured by the first UV lamp 212, and enters multiple digital printing units for printing.

[0040] The feeding roller group 219, the pulling roller group 218, and the pulling roller group II 405 have the same rotation speed and direction; they are respectively controlled uniformly by the external industrial control computer 3. The feeding servo motor driving the feeding roller group 219 and the pulling servo motor driving the pulling of the pulling roller group 218 rotate continuously respectively.

[0041] The pulling roller group Feed the printed material into the digital printing unit. The digital unit consists of the first color mark electric eye 401, multiple groups of digital printing machines 406, printing guide rollers 402, cold water rollers 403, the second UV lamp 404, the material pulling roller group II 405, etc. There are multiple printing guide rollers 402.

[0042] The material pulling roller group II 405 and the material pulling roller group 218 are mounted on the frame in parallel. The second UV lamp 404 irradiates on the cold water roller 403. The first color mark electric eye 401 identifies the color mark of the first printing unit (flexographic printing) and transmits the position information to the digital printing machine 406 for positioning printing. The material after digital printing passes through multiple printing guide rollers 402 and is cured by the second UV lamp 404 at the cold water roller 403. The material pulling roller group II 405 conveys the material after digital printing to the flexographic varnishing / laminating unit.

[0043] Multiple digital printing machines 406 can be arranged sequentially or staggered. After passing through the cold water roller 403 behind the last digital printing machine (the cold water roller 403 is placed on one side of the second UV lamp 404, and the position of the cold water roller 403 is slightly lower than that of the printing guide roller 402, which is set to ensure the tension of the material), it enters the gap between the upper and lower rollers in the material pulling roller group II 405 and passes through smoothly.

[0044] The material enters the flexographic varnishing / laminating unit from the material pulling roller group II 405. The flexographic varnishing / laminating unit is a full-rotation working unit. A laminating part is arranged on one side of the flexographic varnishing part 501. A film unwinding shaft 503 is arranged above the laminating part, a pressing roller group 502 is arranged below the film unwinding shaft 503, and a varnishing bottom roller 505 is arranged above the side of the pressing roller group 502. The flexographic varnishing part 501 can be controlled by a clutch to achieve the state of whether the varnishing bottom roller 505 and the flexographic varnishing part 501 are separated or pressed. A third UV lamp 506 is arranged below the pressing roller group 502. On one side of the third UV lamp 506 is the feeding roller group III 602 of the intermittent die-cutting unit.

[0045] The flexographic varnishing part and the laminating part can work simultaneously or one of them can be selected to work alone. Both parts are to achieve the surface finishing effect of the printed matter, and which part to work is determined according to the different requirements of the printed matter. When the flexographic varnishing part works alone, the moving roller 507 in the pressing roller group 502 is separated from the fixed roller (the left roller in the figure) to achieve off-pressing. The material for printing and varnishing passes through the gap of the pressing roller group and is cured by the third UV lamp 506 and then conveyed to the intermittent die-cutting unit. When the laminating part works alone, the flexographic varnishing part and the third UV lamp 506 do not work.

[0046] The feeding roller group Ⅲ 602 in the intermittent die-cutting unit is located at the lower left of the unit. Above the feeding roller group Ⅲ 602, a second color mark electric eye 601 is transposed. The swing rod group Ⅲ in the unit is located at the bottom. Above the swing rod group Ⅲ, a flat-bed die-cutting part and / or a rotary die-cutting roller part are arranged. On one side of the flat-bed die-cutting part and / or the rotary die-cutting roller part, a pulling roller group Ⅲ 612 is arranged. On one side of the pulling roller group Ⅲ 612, a winding and waste collecting unit is arranged.

[0047] The swing rod group Ⅲ consists of a second swing rod servo motor 603, a second toothed belt 604, a second swing rod guide roller 605 and other guide rollers, and has the same structure as the swing rod group in the flexographic printing and cold stamping laminating unit. The structure is the same.

[0048] The printed material passes through the feeding roller group Ⅲ 602 and then adheres to the surface of the left part of the guide rollers of the swing rod group Ⅲ. When manually controlled to pass through the detection guide roller 609, the second color mark electric eye 601 performs detection and positioning to determine whether to enter the rotary die-cutting roller group 610 (if the rotary die-cutting roller group is used in large quantities) for die-cutting or enter the flat-bed die-cutting part 611 (if entering the flat-bed die-cutting for small batches) for die-cutting.

[0049] The second color mark electric eye 601 identifies the color mark of the first printing unit (flexographic printing) and transmits the position information to the rotary die-cutting roller group (or the flat-bed die-cutting part) for positioning die-cutting; the printed material passes through the detection guide roller 609. If it is conveyed upward into the rotary die-cutting roller group 610, rotary die-cutting is realized; if it is conveyed to the right, it enters the flat-bed die-cutting part 611 to realize flat-bed die-cutting. Which die-cutting method to specifically select is determined by the output of the printed matter and the actual situation of the customer. The feeding roller group Ⅲ 602 and the pulling roller group Ⅲ 612 have the same rotation speed and the same rotation direction. When the third swing rod servo motor 603 rotates clockwise and counterclockwise alternately, the die-cutting unit is in an intermittent working mode. In the intermittent working mode, any one of the rotary die-cutting roller group or the flat-bed die-cutting part can be selected for work. At this time, only a part of the die-cutting knife lines can be pasted on the surface of the rotary die-cutting roller. When the third swing rod servo motor 603 does not rotate, the die-cutting unit is in a full-rotation working mode. In the full-rotation working mode, only the rotary die-cutting roller group 610 works, and the surface of the rotary die-cutting roller can be covered with a full circle of die-cutting knife lines.

[0050] The printed material after die-cutting passes through the pulling roller group Ⅲ 612 and is peeled off at the peeling roller group 703 in the winding and waste collecting unit through multiple guide rollers. The waste edge is wound up by the waste collecting shaft upward, and the finished product goes downward and is wound up at the winding shaft through the guide rollers.

The content such as the left side or the right side expressed is also in the order from left to right as shown in the drawing, and does not mean that it must be set on the left side in the protection scope.

[0052] In addition to the examples given in the above embodiments, an offset printing unit, a hot stamping unit, etc. can also be arranged. The overall structure of each unit includes a color mark electric eye, an intermittent (fully rotating) material pulling part, and a related printing unit or a surface finishing unit. The operating principles of the color mark electric eye, the intermittent (fully rotating) material pulling part, and the related printing unit are also the same as the foregoing content.

No matter which units are selected and configured together, they are all uniformly controlled by the program A of the external industrial control computer. A flexographic printing unit, a surface finishing hot stamping unit, etc. can also be installed in front of the die-cutting unit, and a slitting unit, etc. can be installed behind the die-cutting unit. The above units are installed in parallel on the frame. The layout sequence of printing units such as the intermittent (fully rotating) flexographic printing and cold stamping laminating unit, the digital printing unit, and the screen printing unit, as well as the finishing units can be arbitrarily arranged according to the usage of customers, and their positions (before the equipment is formed) can be replaced. The printing and surface finishing units are placed on the left side (front side), and the post-printing forming units (such as die-cutting, slitting, etc.) are placed on the right side (rear side).
