Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in the application and the feature in embodiment can phases
Combination mutually.Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Fig. 2 is the structural representation of the printing equipment with curling calibration function according to this utility model one embodiment.
As in figure 2 it is shown, along sheet transport direction, printing equipment includes paper roll supporting mechanism 1, curling correction mechanism 2, printing mechanism 3, with
And drive mechanism (not shown).
Paper roll supporting mechanism 1 is used for supporting paper roll, and paper roll supporting mechanism 1 includes support shaft 11, support shaft 11 and paper roll 12
Core cylinder grafting, make when the paper on paper roll 12 is pulled, paper roll 12 can roll relative to support shaft 11.
Printing mechanism 3 is in print on paper printing set in advance content.Printing mechanism 3 can be thermal printer
Structure, it is also possible to be the printing mechanisms such as pin type, ink-jet, laser.In the present embodiment, printing mechanism 3 is thermal print mechanism, including printing
31 and printing rubber roller 32, printhead 31 is tangent with printing rubber roller 32 to be coordinated, and printing rubber roller 32 is at the driving backspin of drive mechanism
Turning, drive paper to printing mechanism 3 downstream transmission between printhead 31 and printing rubber roller 32, meanwhile, printhead 31 is at paper
