In a traditional battery piece printing table, the table surface is exposed outside, and a battery piece is in direct contact with the table surface of the battery piece printing table. The traditional battery piece printing table has the following defects: firstly, after printing is finished, the battery piece is manually taken down from a battery piece printing table so as to carry out blanking on the battery piece; secondly, printing paste on the battery piece directly drops on the table-board, so that frequent cleaning of the table-board is needed, and printing efficiency is affected.

In order to overcome the defects of the traditional battery piece printing table, the applicant develops a novel battery piece printing table, wherein a paper placing reel and a paper collecting reel are additionally arranged on two sides of the battery piece printing table, roll paper is arranged on the paper placing reel, and the roll paper discharged from the paper placing reel bypasses the table board of the battery piece printing table and then is wound on the paper collecting reel. When the printed battery piece needs to be driven to horizontally discharge or the printed polluted roll paper needs to be replaced, the paper releasing reel and the paper collecting reel are driven to rotate in the same direction, so that the roll paper is released by the paper releasing reel and is wound by the paper collecting reel.

In order to enable the roll paper to be attached to the table top of the battery piece printing table in a tightening state all the time, the unwinding speed of the paper unwinding reel and the winding speed of the paper winding reel must be ensured to be the same. However, the thickness of the roll paper on the paper feeding roll and the thickness of the roll paper on the paper delivery roll are both in a changing state, so in order to keep the unwinding speed of the paper feeding roll and the winding speed of the paper delivery roll consistent, the current method is: the two sets of driving mechanisms are arranged to respectively drive the paper placing reel and the paper collecting reel to rotate, and then the two sets of driving mechanisms are subjected to matching control through a complex control algorithm, so that the mode undoubtedly increases the production cost of the battery piece printing table and increases the operation difficulty.
