The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Operation principle of the present utility model is as follows:
A kind of journal printer with paper tension detection mechanism, comprise print member 13, support 1, take-up roll 9, collection motor 30, transmission mechanism, sheet feed shaft 28, paper locating shaft 3, baffle plate 4 and control circuit, take-up roll 9 can be rotated to support on the support 1, and paper roll baffle plate 15 is installed in take-up roll 9 both sides, take-up roll 9 is connected with collection motor 30 by transmission mechanism, transmission mechanism is by motor gear 29, three travelling gears 7 and a gear wheel 17 are formed, motor gear 29 is fixedly mounted on the main shaft of collection motor 30, motor gear 29 and first travelling gear 7 engagements, first travelling gear 7 also meshes with second travelling gear 7, second travelling gear 7 meshes with the 3rd travelling gear 7 again, the 3rd travelling gear 7 also meshes with gear wheel 17, gear wheel 17 is fixedly mounted on the take-up roll 9, sheet feed shaft 28 can be rotated to support on the support 1, paper locating shaft 3 and baffle plate 4 are installed in take-up roll 9 belows, paper locating shaft 3 is supported by support 1, the control end of the control end of collection motor 30 and print member 13 is connected with control circuit, also comprise the paper force checking device that is installed in print member 13 places, this paper force checking device is by photoelectric sensor 24, survey reel 33, hinging supporting shaft 32, driver blade 36, extension spring 38 and extension spring fixed axis 34 are formed, hinging supporting shaft 32 is fixedlyed connected with support 1, driver blade 36 is hinged with hinging supporting shaft 32, and an end of driver blade 36 is connected with survey reel 33, the other end is connected with extension spring 38, the other end of extension spring 38 is connected with extension spring fixed axis 34, extension spring fixed axis 34 is fixed on the support 1, photoelectric sensor 24 is installed in driver blade 36 places, and the transducing signal input of control circuit links to each other with photoelectric sensor 24.
As shown in Figure 1, 2, a side that is connected with extension spring 38 of driver blade 36 top is equipped with alignment pin 35, and alignment pin 35 is fixedlyed connected with support 1.
As shown in Figure 3, control circuit comprises: single-chip microcomputer, the serial port circuit that links to each other with the computer printout signal input part of single-chip microcomputer, first drive circuit that is used to drive collection motor 30 that links to each other with the control output end of single-chip microcomputer, second drive circuit that is used to drive print member 13 that links to each other with the control output end of single-chip microcomputer; Single-chip microcomputer the transducing signal input link to each other with photoelectric sensor 24.The model of single-chip microcomputer is S3C44BOX01.
Shown in Fig. 1～4, the temperature-sensitive paper roll is fixed on the sheet feed shaft 28, and the guiding by paper locating shaft 3 and baffle plate 4 is admitted to print member 13, is pressed in then to survey on the reel 33, and an end of final paper roll is fixed on the take-up roll 9.When print member 13 is not worked, one end of paper is fixed on the take-up roll 9, its other end is fixed on the sheet feed shaft 28, thereby the two ends of paper are fixed and are in a kind of tension like this, heat-sensitive paper is pressed in to be surveyed on the reel 33, the pulling force that paper overcomes extension spring 38 by self tension force will be surveyed reel 33 by driver blade 36 by extension spring 38, extension spring fixed axis 34 and locating shaft 35 and be pressed onto a position, this position is called position of rest, position of rest can detect by photoelectric sensor 24, after photoelectric sensor 24 detected position of rest, collection motor 30 was not worked; When this structure receives the type information order that computer sends by serial port circuit after, print member 13 is just started working, because heat-sensitive paper promptly is sent after printing, and collection motor 30 is not received the collection signal, therefore take-up roll 9 does not carry out collection work, this just makes the heat-sensitive paper that is pressed on the survey reel 33 constantly fluff and arch upward gradually backward, surveys the effect that therefore reel 33 has removed paper power.At this moment, surveying the pulling force of reel 33 by extension spring 38 returns to and is not subjected to the paper masterpiece time spent by the initial position of extension spring 38, extension spring fixed axis 34 and locating shaft 35 location, photoelectric sensor 24 does not detect the signal of position of rest, just detection signal is passed to single-chip microcomputer, single-chip microcomputer rotates by first drive circuit control collection motor 30.After collection motor 30 rotates, drive the rotation of take-up roll 9 by driving motor 7, thereby realize the recovery of paper, when print member 13 stops to print, take-up roll 9 reclaims heat-sensitive papers and detects position of rest and control collection motor 30 back that shuts down and finish the recovery task up to photoelectric sensor 24.
The utility model not only effectively solves the type fount distortion that paper in the removal process causes the pulling of print member, the flimsy problem of printing of parts; And can select the collection motor of any big or small power according to the size that reclaims paper roll.
