DETAILED DESCRIPTION

[0016] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0017] In one embodiment, Figure 1-Figure 8 As shown: This embodiment provides a humidification and static removal system for a printing press, including a conveyor frame 1, a printing press body 12 is provided on the discharge side of the conveyor frame 1, and the conveyor frame 1 includes a support frame part 2, a conveying part 3, a humidification part 4, a loading part 5 and a static removal part 6; The conveying part 3 includes a first conveying roller 7 and a second conveying roller 8 mounted on the support part 2, and the first conveying roller 7 and the second conveying roller 8 are located on the feeding side of the printing machine body 2; The humidifying part 4 includes a humidifying tube 9 fixed on the support part 2 and a plurality of atomizing nozzles 10 arranged on the humidifying tube 9, the atomizing nozzles 10 are located above the feeding side of the first conveying roller 7, and the spray direction is toward the outside of the printing paper; the plurality of atomizing nozzles 10 are arranged in a row, and the mist outlet ends of the plurality of atomizing nozzles 10 are in the tangential direction of the first conveying roller 7; The feeding part 5 includes a material roller 11 connected to the support part 2, the material roller 11 is located above the second conveying roller 8, the material roller 11 is wound with printing paper, and is used to convey the printing paper to the first conveying roller 7, and the discharge end of the printing paper is conveyed to the second conveying roller 8 through the first conveying roller 7 and enters the printing machine body 12 through the feeding port; The static electricity removal part 6 includes a humidifying plate 13 fixed in the support part 2, one end of the humidifying plate 13 is inclined upward and close to the atomizing nozzle 10, and the other end of the humidifying plate 13 extends to the bottom side of the first conveying roller 7 and the second conveying roller 8; The static electricity removal part 6 further includes a horizontal section 14 formed on the humidifying plate 13 at one time, and also includes a raised end 15 formed along the horizontal section 14 at one time; The static electricity removal part 6 further includes a liquid seepage tube 24 connected to the raised end 15 , and the other end of the liquid seepage tube 24 is connected to the printer body 12 .

[0018] The atomizing nozzle 10 directs the mist toward the first conveying roller 7 to spray the mist, so as to atomize and moisturize the paper surface being conveyed toward the second conveying roller 8. The existing mist method for eliminating static electricity on the paper surface can also be applied in the present invention to eliminate static electricity when the paper is conveyed toward the printing machine body 12. For example, a printing machine with a static electricity removal device disclosed in Chinese patent application number 202020723437.9 discloses a humidification technology of a humidifier method, which is consistent with the humidification principle of the present invention. However, the present invention not only provides a humidifying element, but also provides a humidifying plate 13 at the bottom of the first conveying roller 7 and the second conveying roller 8, and provides a wick cotton 17 in the horizontal section 14 of the humidifying plate 13. The wick cotton 17 is rectangular, one side of which falls in the horizontal section 14, and the other side is passed through the humidifying tube 18. Due to the feedback of humidified water vapor When it reaches the paper, it will fall into the horizontal section 14 of the humidifying plate 13 as the paper is transported downward, and will be intercepted by the raised end 15 and collected in the horizontal section 14. This part of the water vapor will be absorbed by the wick cotton 17. Since the wick cotton 17 is a linear material with strong water absorption, the wick cotton 17 will absorb the water vapor collected in the horizontal section 14. According to the water absorption principle of the wick cotton 17, the water vapor will fill the entire wick cotton 17. Since the top part of the wick cotton 17 is passed through the humidifying tube 18, and the tube wall of the humidifying tube 18 contacts the inner side of the printing paper, and the humidifying tube 18 is inserted on the inner side of the printing paper, and the humidifying tube 18 is provided with a humidifying hole 19 that contacts the inner surface of the printing paper, when the water vapor is sucked into the humidifying tube 18, it will act on the inner surface of the paper through the humidifying hole 19, so that the static layer existing on the inner side of the paper disappears.

[0019] In addition, part of the water vapor in the humidifying plate 13 will be sent to the anchor bolt mounting hole 23 opened at the bottom of the printing machine body 12 through the seepage pipe 24. Since the anchor bolt mounting hole 23 is used to install the anchor bolt, in order to reduce vibration during installation of the printing machine body 12, it is necessary to fix it to the ground through the anchor bolt. Moreover, the anchor bolt is also equivalent to a grounding bolt, which is used to release the static electricity generated when the printing machine body 12 is working to the ground. It is often found in the prior art that the static electricity released when the printing machine body 12 is working causes discomfort to the staff. The traditional way is to manually pour some water on the anchor bolt to form a grounding protection between the equipment and the ground. It can be seen that in order to make water seep into the anchor bolts, the water used in the present invention comes from the humidifying plate 13, and when the seepage pipe 24 is injected into the anchor bolts, a large displacement is not required. It is only necessary to have water seep into the anchor bolts to ground the anchor bolts to the ground, and then the anchor bolts release the static electricity on the printer body 12 to the ground to solve this problem. Since the water in the present invention comes from the humidifying plate 13, and the water in the humidifying plate 13 comes from the atomizing nozzle 10 on the conveying side, the present invention realizes the unified combination of static electricity elimination on the paper conveying side and static electricity elimination on the printer body 12 on the printing side. In addition, in order to release static electricity from the printer body 12, there is no need to manually pour water into the anchor bolts as in the prior art, which is easy to operate and saves labor.

[0020] In summary, when the paper is conveyed from the first conveying roller 7 and the second conveying roller 8 to the printing machine body 12, the outer side of the paper is atomized and humidified by the water vapor sprayed from the atomizing nozzle 10, and the static electricity on the outer side is eliminated. The present invention collects the mist through the humidifying plate 13 and then reapplies it to the inner side of the paper through the wick cotton 17, so that the static electricity on the inner side of the paper is also eliminated, so that the static electricity on both the inner and outer sides of the paper is eliminated, which is better than the prior art.

[0021] In order to improve the humidification efficiency of the humidification tube 18 on the inner side of the paper, the number of humidification holes 19 opened on the humidification tube 18 is several, and in order to make the inner side of the paper evenly heated and better eliminate static electricity, Figure 3 , Figure 4 As shown, the humidification holes 19 are evenly opened along the circumference of the humidification tube 18 .

[0022] like Figure 3 , Figure 4 , Figure 7 as well as Figure 8As shown, the humidifying tube 18 is filled with a reinforcing rod 20, the part of the wick cotton 17 located in the humidifying tube 18 passes through the reinforcing rod 20, and the two ends of the reinforcing rod 20 are installed on the two hanging ears 16. When the inner surface of the paper is transported toward the printing machine body 2, the inner surface of the paper will rub against the humidifying tube 18 to rotate, and the humidifying tube 18 will rotate around the periphery of all the wick cotton 17, and at the same time, it will also rotate with all the humidifying holes 19. All the humidifying holes 19 will throw water vapor to the inner surface of the paper, so that the efficiency of static electricity elimination on the inner surface of the paper is further improved. Figure 7 , Figure 8 As shown, the wick cotton 17 is wound by a plurality of wick cotton units 22, and the two ends of the wick cotton unit 22 are locked and fixed by lock buckles 21. Since the wick cotton 17 is installed with lock buckles 21 at both ends in the humidifying tube 18, and the two ends of the reinforcing rod 20 pass through the two lock buckles 21, and the inner ends of the two lock buckles 21 are buckled on the two ends of the humidifying tube 18, when the inner surface of the paper rubs against the humidifying tube 18 and rotates, the two ends of the humidifying tube 18 will rotate with the lock buckles 21 at both ends as the rotation points, and the middle of the lock buckles 21 at both ends is provided with a perforation, and the two ends of the reinforcing rod 20 pass through the two lock buckles 21 and are installed on the ears 16 at both sides, all the two ends of the wick cotton unit 22 are locked. The ends are fixed by two lock buckles 21, and the inner parts of all the wick cotton units 22 are located in the humidifying tube 18. The reinforcing rod 20 is also inserted into all the wick cotton units 22. The reinforcing rod 20 supports the wick cotton units 22 and is also used to support the two lock buckles 21, so that the installation position of the wick cotton 17 is fixed. When the inner side of the paper is transported, the humidifying tube 18 can only be driven to rotate by the friction effect. When the humidifying tube 18 rotates, a friction effect is formed between the inner wall of the tube cavity and the wick cotton 17, and the water vapor absorbed in the wick cotton 17 is more effectively thrown to the inner side of the paper through the humidifying hole 19, so as to effectively eliminate the static electricity on the inner side of the paper. Of course, during the actual assembly, the outside of the two lock buckles 21 will be fixed with screws between the same side ear 16 to prevent the lock buckle 21 from rotating with the humidifying tube 18, and also to prevent the two lock buckles 21 from moving back and forth in the width direction, so as to ensure that the positions of the two lock buckles 21 are fixed.

[0023] As a further preferred embodiment, one end of the seepage tube 24 connected to the horizontal section 14 is vertically downward, and an anchor bolt mounting hole 23 is provided at the bottom of the printing machine body 12. The other end of the seepage tube 24 extends toward the printing machine body 12 and is inserted into the anchor bolt mounting hole 23. The end of the seepage tube 24 inserted into the anchor bolt mounting hole 23 is attached to the inner wall of the anchor bolt mounting hole 23. When part of the moisture collected in the humidifying plate 13 leaks along the seepage tube 24 to the anchor bolt mounting hole 23, it will flow along the hole wall of the anchor bolt mounting hole 23 to the ground, while also avoiding obstacles to the installation of the anchor bolts.

[0024] One end of the humidifying plate 13 close to the atomizing nozzle 10 is located at the bottom of the atomizing nozzle 10, and the two sides of the humidifying plate 13 are connected to the two inner wall surfaces of the support frame part 2. The mist sprayed by the atomizing nozzle 10 acts on the outside of the paper, and after being reflected by the outside of the paper, it falls into the humidifying plate 13 in the form of water droplets. Of course, because the water acts on the paper surface in the form of an atomized spray, it is not sprayed on the paper surface in the form of a nozzle, and the industrial printing paper is thicker, the mist will not cause the paper surface to be excessively moist and break. When the paper is electrostatically treated and conveyed from the feed port to the printing machine body 12, a drying device will be set near the feed port of the printing machine body 12 like the prior art (application number 202020723437.9), and the paper surface is dried or fed into the printing machine body 12 when the printing machine body 12 is printed.

This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field.
