The working method comprises the following steps: the front section of the gripper bars clamps the paper to be processed; the front-back reciprocating mechanism drives the gripper bars to operate backwards to place the clamped paper at a working station of the host machine and then release the paper; the dental row returns to the original position; when the operation of the host machine is finished, the gripper bars are opened, the front sections clamp the paper to be processed, and the rear sections clamp the processed paper; when the paper to be processed moves to the working station of the host machine, the gripper bar stops moving and opens, the gripper bar front section places the clamped paper to be processed at the working station of the host machine, and the gripper bar rear section places the processed paper on the conveying device. The patent utilizes a single set of gripper bar devices to carry new paper to be processed into a host machine working station, and simultaneously carries the processed paper to a conveying device. However, this technique does not allow for continuous feeding of the paper to be processed into the host machine station.

When the gripper bar device disclosed in the patent works, after paper reaches a designated position, grippers on the upper plate of the reciprocating gripper bar grip the paper on the upper plate of the reciprocating gripper bar, the servo motor starts to rotate anticlockwise, and the upper plate of the reciprocating gripper bar starts to move from right to left; at the moment, the reciprocating gripper bar lower plate synchronously moves from left to right to prepare for next paper taking; finally, the upper plate of the reciprocating gripper bar moves to a processing area, and the lower plate of the reciprocating gripper bar moves to a paper taking area; when the second paper reaches the paper taking area, the paper is gripped to the lower plate of the reciprocating gripper bar by the grippers on the lower plate of the reciprocating gripper bar, the grippers on the upper plate of the reciprocating gripper bar start to be released, and the processed paper is delivered to the next working procedure; the servo motor starts to rotate clockwise, at the moment, the reciprocating gripper bar lower plate starts to move right to left, and the reciprocating gripper bar upper plate synchronously moves back from left to right, so that preparation is made for next paper taking; finally, the reciprocating gripper bar lower plate moves to the processing area, and the reciprocating gripper bar upper plate moves to the paper taking area.
The patent technology utilizes the upper tooth row and the lower tooth row, and drives the two tooth rows to alternately perform linear reciprocating motion by alternately performing forward rotation and reverse rotation through the motor, so that continuous paper conveying is realized, and the working efficiency is improved. However, in the technology of the patent, the upper and lower rows of teeth respectively carry out the paper conveying work on different height planes, which requires that the paper heights of the initial position and the processing position are required to be continuously changed so as to adapt to the height planes of the upper and lower rows of teeth, thereby causing inaccurate positioning of the paper or inconvenience in processing the paper and affecting the working efficiency.
