The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
First embodiment
Fig. 2 shows the side view according to the printer of band paper curl-correcting device of the present utility model.As shown in Figure 2, printer 1 comprises along the appearance paper assembly 2 of arranging successively on the printing paper throughput direction, curling assembly 3, print components 4, cutter assembly 5, the exit slot 6 proofreaied and correct of paper.
Wherein, hold paper assembly 2 and be used for the storage print roll web; Paper curls and proofreaies and correct the bending that assembly 3 is used to proofread and correct paper, keeps print paper smooth; Print components 4 is used for printing the predefined content of printer on roll web; Cutter assembly 5 is used for continuous roll web is cut off according to predefined length; Exit slot 6 is used for the paper after cutting off is discharged printer.
Under printer transmission system (not shown) drives, the calm paper assembly 2 of paper is delivered to the curling assembly 3 of proofreading and correct of paper, after proofreading and correct flattening, assembly 3 is delivered to print components 4 through curling correction of paper, by print components 4 at paper surface print image or literal, finish printing back paper and be cut off at cutter assembly 5 places, the paper after the cut-out is discharged printers from exit slot 6.
The side view of printer under the state of uncapping that has the curling calibration function of paper shown in Figure 3.As shown in Figure 3, print components 4 comprises printhead 41 and prints rubber roll 42, wherein printhead 41 is fixed on the printer lower house 12, printing rubber roll 42 is fixed on the printer upper shell 11, printer upper shell 11 is hinged with printer lower house 12, can be with respect to printer lower house 12 Unscrews or closure.
When printer upper shell 11 is closed with respect to printer lower house 12, printhead 41 is printed rubber roll 42 and is rotated under transmission system drives with to print rubber roll 42 tangent, drive paper between printhead 41 and printing rubber roll 42 to print components 4 downstream transmission, simultaneously, printhead 41 prints.
Fig. 4 is the structural representation according to first embodiment of the curl-correcting device of printer of the present utility model.As shown in Figure 4, the curling assembly 3 of proofreading and correct of paper comprises correcting member 31, front paper pressing spare 32, and back platen 33.
When printer upper shell 11 was closed with respect to printer lower house 12, along the printing paper throughput direction, front paper pressing spare 32 closed on and holds paper assembly 2, and correcting member 31 is positioned at the downstream of front paper pressing spare 32, and back platen 33 is positioned at the downstream of correcting member 31.
In the present embodiment, front paper pressing spare 32 and back platen 33 all are arranged on the printer upper shell 11, and correcting member 31 is arranged on the printer lower house 12.
When printer upper shell 11 was opened with respect to printer lower house 12, as shown in Figure 3, calibrated 31 top of paper was to exit slot 6 places.
When printer upper shell 11 is closed with respect to printer lower house 12, as shown in Figure 4, print paper is depressed by front paper pressing spare 31 in correcting member 31 upstreams, printing paper is depressed by back platen 33 in correcting member 31 downstreams, printing paper is discharged printer by print components 4, cutter assembly 5 from exit slot 6 then.
When printer upper shell 11 was closed with respect to printer lower house 12, front paper pressing spare 32 flexiblely was pressed on the correcting member 31, and correcting member 31 is with afterwards to be provided with certain altitude between the platen 33 poor.
Along the printing paper throughput direction, in correcting member 31 downstreams, rotate drive owing to print rubber roll 42, paper then is subjected to pulling force f2 effect downstream, and in correcting member 31 upstreams, because will drive paper roll rotates, need overcome the deadweight of paper roll, so paper is subjected to the resistance f1 effect of directed upstream, simultaneously, because the 32 pressure effects of front paper pressing spare, paper also is subjected to the effect of frictional force N on correcting member 31.
Under the effect of stressed N, f1, f2, paper produces curl opposite with original paper curl direction at correcting member 31 places, offset paper and curled, and reaches the curling purpose of proofreading and correct of paper.
Second embodiment:
Fig. 5 is the structural representation according to second embodiment of the curl-correcting device of printer of the present utility model.As shown in Figure 5, present embodiment and the above-mentioned first embodiment difference are that front paper pressing spare 32 is to be with flexible roller shape structure, and correcting member 31 is platy structures, and back platen 33 is shape structures.
Wherein, back platen 33 can be arranged on the printer upper shell 11, also can be arranged on the printer lower house 12.
In the utility model, close on paper storehouse one side by correcting member and increase pressure at the paper curl-correcting device of printer, solved the hypodynamic problem of the curling correction of paper, particularly consumed gradually, under the situation that the correcting member place suffered pulling force of paper diminishes at paper roll.
Be preferred embodiment of the present utility model only below, be not limited to the utility model, for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
