The implementation principle of the paper roll for the printer for preventing ink adhesion of the embodiment of the application is as follows: when the paper is in the time of through paper roll body 1, barb tooth 3 in the isolation layer 2 outside can support the paper, because the area of contact of every barb tooth 3 and paper is less, has the space between the adjacent barb tooth 3, and the paper is at the in-process of conveying, and barb tooth 3 is difficult for smearing the printing ink of printing at the paper dirty.
Example two:
the embodiment of the application discloses antiseized black paper roll for printing machine.
Referring to fig. 2 and 3, the difference between the second embodiment and the first embodiment is: the isolation layer 2 is made of hard material, such as plastic or metal material. The isolation layer 2 comprises a left half shell 21 and a right half shell 22 which are buckled together, and the left half shell 21 and the right half shell 22 are buckled together to form a cylindrical structure capable of sheathing the paper roller body 1 inside. The barb teeth 3 are densely distributed on the outer side surfaces of the left and right half shells 21 and 22. The barb teeth 3 are densely distributed on the outer side surfaces of the left half shell 21 and the right half shell 22.
Referring to fig. 3 and 4, the outer sides of both ends of the left half shell 21 and the right half shell 22 are provided with clamping grooves 23, and when the left half shell 21 and the right half shell 22 are fastened together, the clamping grooves 23 at both ends of the left half shell 21 and the right half shell 22 are opposite to each other one by one and form a complete annular groove structure. Both ends of the left half shell 21 and the right half shell 22 are fixed together by a clamp 4 sleeved outside the left half shell 21 and the right half shell 22. The clip 4 is inserted into the annular groove structure formed by the clip groove 23.
Two insertion grooves 11 with the length arranged along the axial direction of the paper roller body 1 are arranged on the outer side surface of the paper roller body 1, and the two insertion grooves 11 are symmetrically arranged along the axis of the paper roller body 1. The inner side surfaces of the left half shell 21 and the right half shell 22 are provided with plug blocks 24 which are matched with the plug grooves 11. The plug block 24 on the left housing half 21 is integrally formed with the left housing half 21. The insert block 24 on the right half shell 22 is integrally formed with the right half shell 22. When the left half housing 21 and the right half housing 22 are snapped together and the paper roll body 1 is fitted inside, the insertion block 24 inside the left half housing 21 is inserted into one of the insertion grooves 11, and the insertion block 24 inside the right half housing 22 is inserted into the other insertion groove 11.
Referring to fig. 5, the interior of the roll body 1 is provided with a cavity 12 disposed along the axial direction of the roll body 1, and the cavity 12 communicates the end faces of both ends of the roll body 1. And the air inlet pipe 5 is arranged at two ends of the paper roller body 1, one end of the air inlet pipe is connected with the air inlet pipe 5 which is coaxial with the paper roller body 1 in a rotating mode, and an inner hole of the air inlet pipe 5 is communicated with the inside of the cavity 12. The other end of the paper roller body 1 is connected with an air outlet pipe 6 which is coaxial with the paper roller body 1 in a rotating mode, and the inner hole of the air outlet pipe 6 is communicated with the inside of the cavity 12.
When paper printing, let in hot-air to the inside of paper roll body 1, when hot-air when the cavity 12 inside of flowing through paper roll body 1, hot-air's heat transfer is to paper roll body 1 on, when paper passes through paper roll body 1 to can dry the printing ink on the paper, make the printing ink on the paper be difficult for gluing on the paper roll.
Located inside the cavity 12 is a spiral structure 7 arranged along the axial direction of the roll body 1, the spiral structure 7 including a central shaft 71 arranged along the axial direction of the roll body 1, the axis of the central shaft 71 coinciding with the axis of the roll body 1. The central axis 71 is spaced from the walls of the cavity 12. The helical blade 72 is arranged between the central shaft 71 and the cavity wall of the cavity 12, the helical blade 72 is welded and fixed with the central shaft 71, and the helical blade 72 is welded and fixed with the cavity wall of the cavity 12.
When the hot air enters the inside of the cavity 12, the hot air flows along the spiral blade 72, so that the flowing time of the air in the cavity 12 can be prolonged, and the heat of the hot air can be better transferred to the paper roll body 1.
The implementation principle of the paper roll for the printer of this application embodiment anti-sticking ink is: when the paper prints, be linked together intake pipe 5 with hot-blast wind regime to inject hot-blastly to paper roller body 1 inside cavity 12, hot-blastly when flowing through paper roller body 1 inside cavity 12, make paper roller body 1's temperature rise, when the paper is when passing through paper roller body 1, the heat can be dried the printing ink on the paper.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
