In order to realize that the driving roller support 23 and the fixed part can integrally rotate by taking the output shaft of the sheet feeding motor 28 as a rotation center. The fixed support 27 is provided with a disengaging motor 29, an output shaft of the disengaging motor 29 is fixed with a disengaging cam 25, and when color changing is needed, the driving roller support 23 is driven by the disengaging cam 25 to rotate by taking the output shaft of the sheet feeding motor 28 as a rotation center, so that the driving roller 26 is disengaged from the sheet feeding driven wheel 38 for transmission contact.
In order to ensure that the driving roller 26 is in fit transmission with any one of the sheet feeding driven wheels 38, a driving roller support is connected between the fixed support and the driving roller support to rotate, so that the driving roller is in fit transmission with any one of the sheet feeding driven wheels. When the machine starts to operate, the driving roller 26 is tightly attached to one of the sheet feeding driven wheels 38 due to the acting force of the driving spring, and the sheet feeding motor 28 transmits power to the driving roller 26, so that the sheet feeding driven wheel 38 and the sheet feeding roller 36 are matched to pull the material belt.
When color changing is needed, the output shaft of the disengaging motor 29 rotates for a certain angle, so that the disengaging cam 25 fixed on the disengaging motor rotates to be tightly attached to the inner wall of the driving roller support 23, the output shaft of the sheet feeding motor 28 is taken as a rotating center, the output shaft is ejected for a certain distance, the sheet feeding driving roller 26 is separated from the sheet feeding driven wheel 38, and then color changing operation is carried out; after the color change is completed, the disengaging motor 29 is rotated back to the original position under the action of the driving spring.
Specifically, the fixing support 27 includes a fixing plate, two parallel motor mounting plates are vertically connected to the fixing plate, and the sheet feeding motor 28 and the separation motor 29 are respectively mounted on the motor mounting plates on two sides. The driving roller wheel support 23 comprises a U-shaped part, two groups of bearing mounting holes are formed in two side edges of the U-shaped part, rolling bearings 24 are mounted in the bearing mounting holes, one group of rolling bearings are matched with the driving wheel shaft, and the other group of rolling bearings are matched with an output shaft of the sheet feeding motor. The U-shaped portion is provided with lugs at the corners of the open end, the lugs being provided with bearing mounting holes 231 for seating the rolling bearings 24.
The sheet feeding driving assembly 2 is integrally fixed on the rear side inclined plane at the bottom of the machine head shell, and particularly, the fixing plate can be connected with the rear side inclined plane at the bottom of the machine head shell through screws.
As a variation of the above-described sheet feeding driving assembly 2, it will be understood by those skilled in the art that the sheet feeding motor 28 may also be mounted on the driving roller support 23, and may drive the driving wheel shaft 22 through a synchronous belt transmission mechanism or a gear transmission mechanism, as well as other conventional transmission methods. Meanwhile, the disengaging motor 29 can be installed on the fixed support 27, and directly use its output shaft or disengaging cam, or drive the driving roller support 23 to rotate relative to the fixed support 27 by other means. Or the driving roller support 23 may be slidably connected to the fixed support 27, and the driving roller support 23 linearly moves relative to the fixed support 27 by a linear driving method.
As will be appreciated by those skilled in the art, the sheet feeding drive roller 26 and the sheet feeding driven roller 38 can be frictionally driven in a snug manner, as described above, so that the driving contact and disengagement can be easily switched. Of course, it is not excluded to use a gear mesh transmission, preferably a friction transmission. The gear transmission mode may have some problems, and mainly the piece-feeding driven gear can rotate due to the vibration of the machine operation, so that the piece-feeding driving gear and the piece-feeding driven gear are staggered and cannot be meshed smoothly in the color changing process.
Referring to fig. 9, the principle of the feeding and punching of the material tape 1001 is as follows: the sheet feeding driven wheel 38 and the sheet feeding roller wheel 36 are matched to pull the tape 1001, after the tape 1001 is discharged from the tape reel, the tape passes through the thread passing hole in the iron sheet middle thread 18 and the thread passing hole in the iron sheet lower thread 19 from top to bottom, is guided by the front guide wheel 101 to be fed into the tape limiting groove 151 between the needle bar frame bottom beam 113 and the punching sheet base 15, passes through the rear guide wheel 33, and then passes between the sheet feeding driven wheel 38 and the sheet feeding roller wheel 36. Furthermore, the waste material can freely fall on the ground by gravity after passing between the sheet feeding driven wheel 38 and the sheet feeding roller 36 without providing a collecting tray, and of course, a waste material collecting box can be provided on the ground to collect the waste material. When the material tape 1001 passes through the position between the needle bar frame bottom beam 113 and the punching sheet base 15 corresponding to the punching sheet blanking hole, the needle bar driving assembly 41 drives the punching needle bar assembly 12 to reciprocate up and down, and the punching sheet with the corresponding specification is punched through the punching needle 122.
Compared with the prior art, the sheet feeding driving assembly 2 and the sheet feeding roller assembly 3 have the advantages that the sheet feeding driven wheel 38 and the sheet feeding roller 36 are easy to separate, the sheet feeding driving roller 26 and the sheet feeding driven wheel 38 are easy to separate, and the material belt can be easily threaded.
