Detailed Description
The turn-over structure of the printing machine according to the present invention will be described in further detail with reference to fig. 1 to 3.
The turnover structure of the printing machine comprises a support 1, wherein a first conveying roller 2, a second conveying roller 3 and a third conveying roller 4 for conveying printing stocks are sequentially arranged on the support 1; the first conveying roller 2 and the second conveying roller 3 are arranged in parallel, and a turnover support 5 for turning over the printing stock is arranged between the first conveying roller 2 and the second conveying roller 3;
the turnover bracket 5 comprises a left steering rod 51 and a right steering rod 52, and the left steering rod 51 and the right steering rod 52 are arranged to be opened outwards towards the second conveying roller 3;
the printing stock which finishes the front printing moves to the second conveying roller 3 by bypassing the first conveying roller 2, moves to the left steering rod 51 by bypassing the second conveying roller 3, moves to the right steering rod 52 by bypassing the left steering rod 51, moves to the third conveying roller 4 by bypassing the right steering rod 52, and finally bypasses the third conveying roller 4, so that the back surface of the printing stock faces upwards, and the turn-over operation of the printing stock is realized; the paper is conveyed forwards by a third conveying roller 4, and reverse printing is carried out by a printer; realize the positive and negative quick printing of stock, need not the manual work and carry out the turn-over operation, improve printing efficiency.
