When the pressing force of one or more movable blocks 303 to the outer layer 315 is too small or too large, the pattern depth pressed by the embossing block 316 on the outer layer 315 corresponding to the movable block 303 is too shallow or too deep, which affects not only the beauty of consistent printed patterns, but also the strength of the printed paper. It is ensured that the pressing force of all the movable blocks 303 to the corresponding embossing blocks 316 on the outer layer 315 is kept substantially identical, so that the embossing quality of the embossing blocks 316 to the paper can be ensured. However, the pressing force of the movable block 303 on the corresponding outer layer 315 depends on various factors, such as inconsistent fatigue strength of the elastic band 307 at different positions when used for a long time, which may cause different binding forces of the movable block 303 corresponding to different positions, and thus may cause the above-mentioned problems; for example, the hard extrusion of each extrusion block 312 and the corresponding movable block 303 for a long time, the wear degree of the contact surface of the two is inconsistent, and the extrusion force of each movable block 303 to the corresponding embossing block 316 on the outer layer 315 is also inconsistent. Moreover, since the slide base 310 drives all the extrusion blocks 312 to synchronously move through the sliding blocks 311, when inconsistent extrusion forces of each extrusion block 312 to the corresponding embossing block 316 on the outer layer 315 occur, effective adjustment cannot be performed, and only relevant parts can be replaced, so that the labor capacity of workers is increased and the production efficiency is affected, and the following improvement is made.
Specifically, an air charging block 313 is arranged outside the extrusion block 312, each air charging block 313 is provided with an air charging valve, and air is pre-stored in the air charging block 313; a pressure sensor is provided below the top spring 305, and the pressure sensor can detect the pressure value of the top spring 305 and transmit the pressure value to the controller. When the gaps of the embossing blocks 316 are adjusted, the sliding seat 310 drives all the extrusion blocks 312 to synchronously move through the sliding blocks 311, the extrusion blocks 312 outwards extrude the movable blocks 303 to enable the movable blocks 303 to outwards move, and the movable blocks 303 stably outwards move along the inserting plates 302 under the limiting action of the corresponding inserting grooves 304 on the inserting plates 302, so that the adjusting positions are finally reached. At this time, because the slots 304 on the movable block 303 reversely press the top spring 305, the pressure sensor under the top spring 305 can detect the pressure value of the corresponding movable block 303 on the top spring 305 and transmit the pressure value to the controller, the controller compares the pressure values corresponding to the pressure sensors on each of the plugboards 302, when the detected values of the pressure sensors on one or more plugboards 302 are smaller than the detected values of the pressure sensors on other plugboards 302, the distance of the outward movement of the movable block 303 corresponding to the plugboards 302 is larger than the distance of the outward movement of the other movable block 303, at this time, the inflatable block 313 on the pressing block 312 corresponding to the movable block 303 is deflated by the inflation valve or the inflatable block 313 on the pressing block 312 corresponding to the other movable block 303 is inflated until the detected pressure values of the corresponding pressure sensors on each plugboard 302 are substantially the same (a certain error is allowed) so as to ensure that the pressing force of each inflatable block 313 on the corresponding movable block 303 is substantially the same (a certain error is allowed) and the distance of the outward movement of each movable block 303 is substantially the same, thereby the final pressing effect of the corresponding movable block 303 on the corresponding outer layer 315 is kept substantially consistent. When the value detected by the pressure sensor on one or more plugboards 302 is greater than the value detected by the pressure sensor on the other plugboards 302, it is indicated that the distance of outward movement of the movable block 303 corresponding to the plugboard 302 is smaller than the distance of outward movement of the other movable blocks 303, at this time, the inflatable block 313 on the pressing block 312 corresponding to the movable block 303 is inflated by the inflation valve or the inflatable block 313 on the pressing block 312 corresponding to the other movable block 303 is deflated by the inflation valve until the pressure value detected by the corresponding pressure sensor on each plugboard 302 is substantially the same (a certain error is allowed to exist), so as to ensure that the extrusion force of each inflatable block 313 to the corresponding movable block 303 is substantially the same (a certain error is allowed to exist), and the distance of outward movement of each movable block 303 is substantially the same, so that the extrusion force of the movable block 303 to the embossed block 316 on the corresponding outer layer 315 is substantially consistent, and finally a relatively consistent embossing effect is achieved, and further, the paper embossing effect is ensured.
In addition, the invention also provides an embossing method of the paper embossing device, which comprises the following steps:
