Problems solved by technology

The above-mentioned equipment usually has only one bellows, and the air box is sucked by the exhaust fan to realize the vacuum adsorption of the cardboard. Also carry out ventilation, so must choose high-power exhaust fan, and is not conducive to energy saving
Therefore, this vacuum adsorption method in the prior art has high energy consumption and needs further improvement

Abstract

A printing machine and its paper feeding mechanism. The paper feeding mechanism includes a frame, a bellows part, a conveying part, an exhaust part and a detection part. The bellows part includes a plurality of bellows arranged side by side in succession and transversely to the paperboard conveying direction, each bellows is connected to the suction source through a switching mechanism, and a pair of bellows are arranged above the end of the paper feeding stroke. Photoelectric sensor, during the paper feeding process, the position of the cardboard is checked by the photoelectric sensor, so as to control the action of the cutting mechanism, so that the suction source only needs to exhaust the bellows under the cardboard, which is beneficial to reduce energy consumption, and can choose a higher Low-power suction source equipment, and when the cardboard is sent crookedly, it can stop the machine in time to reduce waste and improve the printing yield.

Description

technical field [0001] The invention relates to the technical field of cardboard printing, in particular to a printing machine and a paper feeding mechanism thereof. Background technique [0002] At present, the printing industry is developing rapidly. In the printing industry, especially the color printing industry with high quality requirements, the requirements for cardboard are getting higher and higher. The cardboard should be avoided from being damaged during the transmission process, so as not to affect the printing effect of the cardboard. Therefore, the vacuum suction paper feeding method that can better protect the cardboard is widely used in printing equipment. The above-mentioned equipment usually has only one bellows, and the air box is sucked by the exhaust fan to realize the vacuum adsorption of the cardboard. Also carry out exhaustion, must select the exhaust fan of high power like this for use, and is unfavorable for energy-saving. Therefore, this vacuum a...
