The specific embodiment

Below by embodiment the utility model is described in further detail.

Embodiment 1

As shown in Figure 1, 2, the conveyer of this embodiment comprises single motor transmission mechanism, the coil paper 1 that can do positive and negative twocouese and rotate, two winding shafts 2 that are used to install described coil paper 1, and winding shaft synchronizing wheel 21, the two ends of described coil paper 1 are wound on respectively on described two winding shafts 2; Two groups of driven shafts 5 and driven synchronizing wheel 51 thereof that described single motor transmission mechanism comprises axle drive shaft 4 and active synchronization thereof wheel 41 and is attached thereto by synchronous belt 6 are installed in two power-transfer clutchs 7 on the described driven synchronizing wheel 51 respectively.Described winding shaft synchronizing wheel 21 is connected with described driven synchronizing wheel 51 by synchronous belt 6 and rotates thereupon, and in two adjacent rotational action of described transmission device, the distance that described coil paper 1 is passed by on positive and negative both direction equates.51, two driven shafts of two driven synchronizing wheels about 5 that every group of driven shaft 5 and driven synchronizing wheel 51 thereof comprise two driven shafts 5 and be set in driven shaft 5 ends relatively, be arranged in parallel, be used.

Active synchronization wheel 41 by the folding of power-transfer clutch 7, can be realized the positive and negative transmission of paper by being with 6 to link together with driven synchronizing wheel 51 synchronously.When left side power-transfer clutch 7 closures and the right power-transfer clutch 7 is opened, then active synchronization wheel 41 drives coil papers 1 according to advancing the transmission of sheet direction, realizes advancing the sheet action before the printing of battery sheet; When left side power-transfer clutch 7 closures and the right power-transfer clutch 7 is opened, then active synchronization wheel 41 drives driven synchronizing wheel 51, and driven synchronizing wheel 51 drives winding shafts 2, and coil paper 1 is realized the slice action after the battery sheet is completed for printing according to the transmission of slice direction.The first coil paper of installing 1 all is positioned at the winding shaft of the right power-transfer clutch 7 sides, through repeated use, more renew paper, the coil paper 1 of the right power-transfer clutch 7 sides is rolled on the winding shaft 2 of left side power-transfer clutch 7 sides gradually, the use that does not stop by coil paper 1, coil paper 1 on the power-transfer clutch 7 side winding shafts 2 of the right is by original tailing off at most gradually, to the last all coil papers 1 are used up, the coil paper 1 of left side power-transfer clutch 7 side winding shafts 2 is minimized on the winding shaft 2 that all coil papers 1 all are wound up into left side power-transfer clutch 7 sides by original, because coil paper 1 diameter on coil paper 1 diameter on the right power-transfer clutch 7 side winding shafts 2 and the left side power-transfer clutch 7 side winding shafts 2 is along with working process gradually changes, what have used so can't calculate coil paper 1 by motor, machine tool control system also can't be judged the coil paper 1 that when more renews, this just need can get back to original position by the counting encoder 8 that links to each other with winding shaft 2 when advancing sheet and slice, calculate the actual use amount of coil paper 1 simultaneously and judge the coil paper 1 that when more renews.
