[0001] The utility model relates to the technical field of digital printing, in particular to a winding structure for digital printing. Background Art

[0002] Digital printing, also known as digital printing or direct imaging printing, is a technology that uses digital information to control the printing process. Compared with traditional analog printing technology, digital printing has higher flexibility and efficiency, and is especially suitable for short-run printing and personalized printing needs. During the printing process, workers need to use a winding structure to wind the printed matter, so as to facilitate subsequent transportation.

[0003] In most of the existing winding devices for digital printing, they often only play a role in winding the printed matter. When it is necessary to divide the printed matter according to the required specifications, additional equipment is required, which directly leads to an increase in production costs, and also increases the complexity of operation and maintenance costs, reducing the overall production efficiency. Summary of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1-4 shown, a rewinding structure for digital printing includes a rewinder body 1;

[0024] A slitting assembly 2 for dividing printed matter is provided on the rewinder body 1;

[0025] Among them, the strip component 2 includes: support side plates 21 symmetrically arranged on one side of the coiling machine body 1, a bottom supporting roller 22 and a cutting roller 23 rotatably arranged between the support side plates 21, and the bottom supporting roller 22 and the cutting roller 23 are symmetrically distributed up and down. One end of the bottom supporting roller 22 and the cutting roller 23 is provided with end gears 24 meshing with each other. At least one set of support socket seats 25 is arranged on the bottom supporting roller 22. One side of the support socket seat 25 is provided with a differential ring seat 26 surrounding the outside of the bottom supporting roller 22. A fixing seat 28 matching the support socket seat 25 is arranged on the cutting roller 23. One side of the fixing seat 28 is provided with a cutting circular knife 29 surrounding the outside of the bottom supporting roller 22. And when cutting, the cutting circular knife 29 closely adheres to one side of the support socket seat 25 close to the differential ring seat 26. A notch part 210 is formed on the fixing seat 28, and a tightening groove 211 penetrating through the notch part 210 is formed on the fixing seat 28. When the device winds the printed matter, the printed matter enters between the bottom supporting roller 22 and the cutting roller 23, and the printed matter is transported by the rotation of the bottom supporting roller 22 and the cutting roller 23. During the transportation process, the support socket seat 25 arranged on the bottom supporting roller 22 supports the printed matter. At this time, the cutting circular knife 29 rotates together with the cutting roller 23, and the division of the printed matter can be realized. A certain height difference is formed between the support socket seat 25 and the differential ring seat 26, which provides space for the movement of the cutting circular knife 29 and avoids the cutting circular knife 29 damaging the support socket seat 25. The cutting circular knife 29 is fixed on the cutting roller 23 by means of bolt fastening. Therefore, the staff can not only adjust the position of the cutting circular knife 29 according to the work needs, but also increase or decrease the number of the cutting circular knives 29 arranged, so as to meet the changeable work needs in actual production. The formed notch part 210 enables the fixing seat 28 to have a certain deformation space, which is convenient for installation and disassembly.

[0026] In this embodiment, specifically, a motor for driving the bottom supporting roller 22 and the cutting roller 23 to rotate is arranged on the support side plate 21, and the tightening groove 211 is used to install bolts to fix the fixing seat 28 on the cutting roller 23.

[0027] In this embodiment, specifically, a positioning pin groove 27 is formed on the support socket seat 25, and the positioning pin groove 27 is used to install bolts to fix the positioning pin groove 27 on the bottom supporting roller 22.

[0028] In this embodiment, specifically, lifting slide rods 3 are symmetrically arranged at the input end of the coiling machine body 1. A protective cover 4 is slidably sleeved on the outer side of the lifting slide rods 3. The protective cover 4 is located on one side of the slitting assembly 2. A viewing window 5 is arranged on the protective cover 4. The viewing window 5 is a transparent acrylic board. On the side of the coiling machine body 1 where the lifting slide rods 3 are arranged, jacking cylinders 6 for driving the protective cover 4 to lift and lower are symmetrically arranged. The driving end of the jacking cylinder 6 is connected to the bottom of the protective cover 4. A limiting roller 7 is arranged at the input end of the coiling machine body 1. The limiting roller 7 is located below the jacking cylinder 6. By arranging the protective cover 4 on one side of the slitting assembly 2, it can effectively prevent the staff from accidentally touching the cutting circular knife 29 during the use of the device, reducing the safety hazards of the device and providing good protection for the staff. When it is necessary to adjust and repair the components in the slitting assembly 2, the protective cover 4 can be driven by the jacking cylinder 6 to descend along the lifting slide rods 3. The arranged viewing window 5 facilitates observing the internal working conditions of the slitting assembly 2.

[0029] In this embodiment, specifically, a deviation rectifier 8 is arranged at the output end of the coiling machine body 1. The deviation rectifier 8 is located on one side of the limiting roller 7. After the material completes the printing process, it enters the deviation rectifier 8 installed in the coiling machine body 1. The position of the material is adjusted by the deviation rectifier 8 to ensure the smooth progress of subsequent conveying. A number of groups of guiding and conveying rollers 9 are arranged inside the coiling machine body 1. By arranging the number of groups of guiding and conveying rollers 9, the printed matter moves along a predetermined path. An upper coiling roller 10 and a lower coiling roller 11 are symmetrically arranged at the output end of the coiling machine body 1. The upper coiling roller 10 and the lower coiling roller 11 are symmetrically distributed up and down. The upper coiling roller 10 and the lower coiling roller 11 are used for coiling printed matter of different widths.
