The driving shaft is connected with the driven synchronizing wheel through the synchronizing belt wheel, and the forward and reverse transmission of the paper rolling component can be realized through the opening and closing of the clutch. When the left clutch is closed and the right clutch is opened, the driving shaft drives the roll paper to transmit along the sheet feeding direction, and the sheet feeding action before the printing of the battery sheet is realized; when the left clutch is closed and the right clutch is opened, the driving shaft drives the driven synchronous wheel, the driven synchronous wheel drives the rotating shaft to rotate, the roll paper is driven in the sheet discharging direction, and the sheet discharging action after the printing of the battery sheet is finished is realized.
The mounted roll paper is positioned on the rotating shaft at the right clutch side, and after being used for multiple times and replaced by new paper, the roll paper at the right clutch side is gradually rolled on the rotating shaft at the left clutch side, the roll paper on the right clutch side rotating shaft gradually decreases from the original roll paper to the maximum through the continuous use of the roll paper until all the roll paper is used up, the roll paper on the left clutch side rotating shaft is wound on the left clutch side rotating shaft from the original minimum to all the roll paper, since the roll paper diameter on the right clutch-side rotating shaft and the roll paper diameter on the left clutch-side rotating shaft are gradually changed with the progress of the operation, therefore, the used amount of the roll paper cannot be calculated through the motor, the machine tool control system cannot judge when the new roll paper is replaced, it is necessary to return to the original position when feeding and discharging sheets by a counting encoder connected to the rotary shaft, and calculate the actual usage amount of the roll paper to determine when to replace the roll paper with new one.
For realizing better effect, this embodiment has still adopted the take-up pulley for the tensioning of the in-process guarantee stock form rotates. Because the stock form is flexible, when the pivot rotated, the stock form can appear the fold phenomenon, and to solve this kind of fold phenomenon, need have certain resistance when the pivot rotated, so this design has increased first take-up pulley 206, second take-up pulley 207 in the one end of first pivot, second pivot respectively. The first tensioning wheel 206 is connected with the first rotating shaft through the first belt 204, the second tensioning wheel 207 is connected with the second rotating shaft through the second belt 205, and the roll paper can be tensioned at any time, so that the roll paper is always in a tensioned state in the forward and reverse rotation processes.
The application also comprises a printing machine arrangement comprising a printing machine and a printing table cooperating with the printing machine for operation, and a printing machine turret as described above. The printing workbench is positioned on the opposite surface of the roll paper assembly, so that roll paper can be effectively conveyed. The printer turret may be rotated along the mounting shaft to adjust the printing of the product on the different support tables.
The application provides a rotary table of a printing machine and a device thereof, which comprises a rotary table body and a paper rolling component arranged on the rotary table body; the turntable body comprises a base and a supporting platform which extends from at least one outer side surface of the base to one side far away from the base, the supporting platform comprises two supporting frames connected with the outer side surface, and the two supporting frames are oppositely arranged and form an accommodating space with the outer side surface; the roll paper assembly comprises at least one rotating shaft, and the roll paper assembly is fixedly arranged in the accommodating space through at least one rotating shaft. Through improving revolving stage body structure, utilize the strengthening rib of revolving stage to do the stock form base, both guaranteed the intensity and the rigidity of revolving stage and made revolving stage body structure small and exquisite again, inertia is little, and the machining precision also is higher than current scheme.
