Front paper locating device for paper feeding machine of offset machine

The utility model discloses a front paper locating device for a paper feeding machine of an offset machine. Oblique blocks are fixed to the position, close to the ground, on the lower portion of a front left locating plate of the paper feeding machine and the position, close to the ground, on the lower portion of a front right locating plate of the paper feeding machine. Hanging plates are assembled on a hanging plate supporting base. One end of a rolling wheel pin shaft penetrates through a spacer bush and a support hole and is exposed, and the other end of the rolling wheel pin shaft is sleeved with a rolling wheel. The rolling wheel is clamped to a guide rail. The portion, exposed out of the support hole, of the rolling wheel pin shaft is sleeved with an elastic piece and is fixed to one side of the hanging plate support through a locking block. A chain is fixed to a connecting block. The connecting block is connected with the hanging plates. According to the technical scheme, the problem that due to the fact that paper is not well located on the paper feeding machine, the paper is fed in a skew mode is solved; due to the fact that the two oblique blocks are fixed to the positions, close to the ground, on the lower portions of the front locating plates of the paper feeding machine, accurate locating can be carried out once more, the locating precision of a paper pile in the front and back direction is improved, and therefore the paper can be printed well in the printing process.
