The round hole is viewed in the plane projection direction of the mounting plate 1.
Referring to fig. 2 and 5, in this embodiment, the adjusting member 7 includes a threaded cylinder 71, a threaded shaft 72, a fixing plate 73 fixed on the mounting plate 1, and a guiding member 74, the threaded cylinder 71 is rotatably connected to the fixing plate 73, one end of the threaded shaft 72 is connected to the baffle 5, the other end is connected to the threaded shaft 72 in a threaded manner, the baffle 5 is slidably connected to the mounting plate 1 through the guiding member 74, and the guiding direction of the guiding member 74 is the same as the extending direction of the threaded shaft 72. In addition, in order to facilitate the hand to rotate the threaded cylinder 71, one end of the threaded cylinder 71, which is far away from the baffle 5, penetrates through the fixing plate 73 and is connected with a rotating handle 75. During adjustment, the baffle 5 can move under the limit of the guide piece 74 by rotating the threaded cylinder 71, so that the baffle 5 and the semicircle of the long circular hole 4 can form a complete circular hole under normal operation conditions, the driven platen roller 3 can be installed, or the baffle 5 can be moved, so that the long circular hole 4 is completely exposed, the driven platen roller 3 can be moved, the gap between the driven platen roller 3 and the driving platen roller 2 can be increased, and the operation is simple and convenient.
The specific structure of the guide 74 described above is: the device comprises two guide rails 741 arranged on the mounting plate 1 and two slide grooves 742 which are arranged on the baffle 5 and are respectively matched with the slide rails in a sliding manner, wherein the extending direction of the slide rails is the same as the extending direction of the threaded shaft 72. In addition, in order to facilitate the positioning and limiting of the baffle 5, the mounting plate 1 is provided with a limiting plate 76 which stops the baffle 5 from continuing to move forwards after the baffle 5 is in place, so that the baffle 5 just forms a round hole with the long round hole 4 of the mounting plate 1 under the limiting and blocking of the limiting plate 76 during the moving adjustment, and the situation that the baffle 5 is over-positioned or not in position is avoided.
The implementation process, i.e., the implementation principle, of the embodiment is as follows: before the roll paper is cut, the roll paper is firstly installed at an installation position, then the baffle 5 is moved to one side far away from the driving press roll by rotating the threaded cylinder 71, the long round holes 4 on the installation plate 1 are completely exposed, then the two driven press rolls 3 are all pushed to one side far away from the driving press roll 2, at the moment, the gap between the driven press roll 3 and the driving press roll 2 is increased, then the free ends of the roll paper respectively penetrate through the gaps between the driven press roll 3 and the driving press roll 2 and then are pulled to a cutting mechanism, after the roll paper sequentially penetrates through the gaps between the driven press roll 3 and the driving press roll 2, the rotating threaded cylinder 71 is adjusted, the baffle 5 is moved to the limiting plate 76, at the moment, the semicircular hole 6 of the baffle 5 and the semicircle of the long round holes 4 on the installation plate 1 just form a whole round hole, the rotating shaft of the driven press roll is just rotatably limited in the whole round hole, and after other mechanisms of the cutting machine are ready, the cutting machine is started. When the roll paper passes through the reverse bending mechanism, the gap between the driven paper pressing roller 3 and the driving paper pressing roller 2 is changed, so that the roll paper passes through the reverse bending mechanism relatively easily, and the efficiency is improved.
Example 2:
in this embodiment, except that the installation mode of the baffle 5 is different from that of the mounting plate 1, the other structures are the same as those of embodiment 1, specifically, in this embodiment, as shown in fig. 6, the baffle 5 is detachably connected with the mounting plate 1 through a bolt, a semicircular hole 6 on the baffle 5 and a semicircle of the long circular hole 4 on the mounting plate 1 form a whole circular hole, and the rotating shaft of the driven platen roller 3 is rotatably inserted into the whole circular hole. When the roll paper passes through the anti-bending mechanism, the baffle 5 is directly detached, the long round holes 4 of the mounting plate 1 are completely exposed, after the roll paper passes through the anti-bending mechanism, the baffle 5 is mounted on the mounting plate 1, and the semicircular holes 6 on the baffle and the semicircle of the long round holes 4 on the mounting plate 1 just form a whole round hole. In this embodiment, the structure is simple as compared with embodiment 1, but the baffle 5 needs to be attached and detached during adjustment.
