Problems solved by technology
The variable-speed paper feeding mechanism must be equipped with a compensation mechanism to reduce vibration, which makes the mechanism more complicated. The variable-speed paper feeding mechanism cannot realize the constant-speed running section of the paper in the movement cycle to improve the efficiency when the paper receiving roller and the paper delivery nozzle mechanism are handed over. Paper feeding stability

The invention discloses a variable speed paper feed mechanism and a fixed groove cam plate thereof. The mechanism comprises a power input shaft, a planetary swing arm, a planetary gear swing arm, a first intermediate shaft, a cam roller, a first transmission gear, the fixed groove cam plate and a paper feed line tape roller, wherein the planetary swing arm is fixed on the power input shaft; the left end of the planetary swing arm is hinged with the planetary gear swing arm; the right end of the planetary gear swing arm is meshed with the first transmission gear fixed on the first intermediate shaft; the left end of the planetary gear swing arm and the cam roller are meshed in a cam groove of the fixed groove cam plate; and the first intermediate shaft is fixed on the fixed groove cam plate and drives the paper feed line tape roller to rotate. The mechanism can achieve that the paper has constant speed operation sections in the period of motion so as to improve the paper skip stability during joint of a paper receiving roller and a paper transferring suction nozzle mechanism while achieving the aim of variable speed paper feed and has simple mechanical structure.
Description
technical field [0001] The invention relates to the field of printing, in particular to a variable-speed paper feeding mechanism and a fixed groove cam plate thereof. Background technique [0002] As the speed of the sheet-fed printing machine continues to increase, the conveying speed of the paper on the feeder table of the paper feeder is also continuously increased. Before each sheet of paper enters the printing unit, it must be accurately positioned by the front gauge and side gauge to ensure accurate overprinting. The front edge of the paper needs to directly lean against the stationary front positioning plate during motion to complete the circumferential positioning of the printed sheet. Therefore, when the conveying speed of the paper is too high, it is very easy to cause faults such as curling of the paper edge and paper rebound when the paper is in contact with the previous positioning plate for positioning, which affects the normal operation of printing. In order ...
