DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0023] Reference Figure 1-5 A printing device for high-precision digital printing includes a digital printing machine 1. The end of the digital printing machine 1 is connected to a mounting plate 2, and a motor 3 is installed on the side of the mounting plate 2. The printing principle of the digital printing machine 1 is the existing technology and will not be described in detail here. The output end of the motor 3 is connected to a winding roller 4, and a paper roll 5 is sleeved on the outer side of the winding roller 4. A rectangular block 6 is provided on the lower side of the digital printing machine 1, and a slot is opened inside the rectangular block 6. The inner wall of the slot is connected to a cross bar 7, and the outer side of the cross bar 7 is respectively sleeved with a sliding sleeve 8. The bottom end of the sliding sleeve 8 is connected to a limit plate 9 through a connecting rod. A slideway adapted to the connecting rod is opened at the bottom end of the rectangular block 6. A moving block 10 is distributed on the side away from the limit plate 9, and the moving block 10 A limit rod 11 is symmetrically connected to the upper side, and a card slot compatible with the limit rod 11 is equidistantly provided at the bottom end of the rectangular block 6. A slider is connected to the inner side of the movable block 10, and a slide slot compatible with the slider is provided on the side of the limit plate 9. A flip mechanism is provided inside the rectangular block 6. Through the setting of the flip mechanism, the rectangular block 6 and the cross bar 7 can be rotated ninety degrees so that the staff can remove the paper roll 5 from the winding roller 4 or install it on the outside of the winding roller 4. The outer wall of the winding roller 4 is provided with limit teeth, similar to the spline shaft in the prior art. A limit groove compatible with the limit teeth is provided at the paper core at the center of the paper roll 5, which is not shown in the figure. Therefore, when the winding roller 4 rotates, the paper roll 5 can be driven to rotate at the same time to realize the transportation of paper.
[0024] Further, see Figure 5It can be seen that the bottom end of the slider is vertically connected to the first spring 12, and the other end of the first spring 12 is connected to the inner wall of the slide groove. Through the connection of the first spring 12, the tightness of the limit rod 11 when it is engaged in the limit groove at the bottom end of the rectangular block 6 can be effectively guaranteed.
[0025] Further, see Figure 3 and Figure 4 It can be known that the flipping mechanism includes a rotating rod 13, and a receiving groove adapted to the rectangular block 6 is opened at the end of the digital printing machine 1. The end of the digital printing machine 1 is inserted with a rotating rod 13, and one end of the rotating rod 13 is connected to the inner wall of the receiving groove through a bearing, and the other end of the rotating rod 13 is connected to a rotating block 14. The top end of the rectangular block 6 is sleeved on the outside of the rotating rod 13. When in use, the rectangular block 6 and the limit plate 9 can be quickly flipped by the mutual cooperation of the rotating rod 13 and the rotating block 14.
[0026] Further, see Figure 4 It can be known that a limit shaft 15 is symmetrically inserted inside the rotating block 14, and the cross-section of the limit shaft 15 is set to a T-shaped structure. The side wall of the digital printing machine 1 is symmetrically provided with positioning grooves adapted to the limit shaft 15. There are four groups of positioning grooves, so that the limit shaft 15 rotated ninety degrees can be limited. The ends of the limit shaft 15 are connected by a linkage rod 17. Through the mutual cooperation of the limit shaft 15 and the second spring 16, the position of the rectangular block 6 and the limit plate 9 can be maintained after rotation.
[0027] Further, see Figure 4 It can be known that a second spring 16 is connected to the outer side of the rotating block 14 , and the other end of the second spring 16 is connected to the limit shaft 15 . The connection of the second spring 16 can ensure the tightness of the limit shaft 15 when it is engaged with the side wall of the digital printing machine 1 .
[0028] Further, see Figure 2 and Figure 3 It can be known that the side of the rectangular block 6 is connected to a support rod 18, and the inner side of the support rod 18 is connected to a scraper 20 through a third spring 19. Brushes are evenly distributed on the side of the scraper 20 close to the paper roll 5. The brush connected to the outside of the scraper 20 can scrape off the paper scraps on the paper roll 5. The elastic characteristics of the third spring 19 itself can make the scraper 20 and the brush always in contact with the paper roll 5.
[0029] Further, see Figure 3 It can be known that the guide rod 21 is symmetrically connected to the side of the scraper 20 away from the paper roll 5, and a groove hole adapted to the guide rod 21 is opened inside the support rod 18. When in use, the scraper 20 can be guided by the mutual cooperation of the guide rod 21 and the groove hole, thereby ensuring the stable translation of the scraper 20.
[0030] Working principle: When the utility model is in use, the staff can first place the device at a suitable position, and then insert the paper roll 5 to the outside of the winding roller 4. After the insertion is completed, the staff can first pull the linkage rod 17, thereby driving the two sets of limit shafts 15 to be forced out from the side wall of the digital printing machine 1 to release the limit on the rotating rod 13, and then the staff can rotate the rotating block 14, so that the rotating rod 13 and the rectangular block 6 can be rotated ninety degrees at the same time. After the rotation is completed, the limit shaft 15 can correspond to the position of the other two sets of positioning grooves opened on the side wall of the digital printing machine 1, so as to realize the limit of the rectangular block 6, and then the staff can pull down the moving block 10 in turn, so that The two groups of limit rods 11 are forced to be pulled out from the bottom end of the rectangular block 6, and then the staff can push the limit plate 9 to make it abut against the side of the paper roll 5. After completing the adjustment of the two groups of 0 positions, the paper roll 5 can be limited. Therefore, when the motor 3 drives the paper roll 5 to be transported, the deviation of the paper roll 5 can be effectively prevented. In addition, through the scraper 20 arranged on the inner side of the support rod 18 and the third spring 19 connected to the side of the scraper 20, the brush distributed on the outer wall of the scraper 20 can always be in contact with the paper roll 5, so that the paper scraps on its outer surface can be scraped off. Since the length of the support rod 18 is relatively long, it can meet the cleaning needs of a narrower paper roll 5. The above is the entire working principle of the utility model.
[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
