In order to achieve the aim, the scheme provides a printing device with the paper jamming prevention function, which comprises a rack, wherein a paper feeding mechanism and a printing machine are arranged on the rack; the paper feeding mechanism comprises a box body, a conveying belt and a cylinder; the box body is connected to a rack, a slide rail is arranged on the rack, a paper suction machine is connected to the slide rail in a sliding mode, and the paper suction machine is connected with the air cylinder; the paper suction machine is arranged above the box body and the conveying belt, the conveying belt is arranged between the box body and the printing machine, the part, in contact with paper, of the paper suction machine is made of metal, the paper suction machine is provided with a cation releaser, the rack is provided with a switch used for controlling the cation releaser, the paper suction machine is periodically contacted with the switch, the conveying belt is provided with an anion releaser, and the acting force of cations on anions is larger than that of the paper suction machine on the paper.
The principle of the scheme is as follows: the paper printing method includes the steps that firstly, paper required for printing is placed on a box body, then a paper suction machine is started to adsorb the paper, at the moment, a cation releaser is in a power-off state, after the paper suction machine adsorbs the paper, a cylinder works to push the paper suction machine to move towards a printing machine along a sliding rail until the paper suction machine is in contact with a switch for controlling the cation releaser, at the moment, the cation releaser is electrified to release cations and enable the paper tape on the paper suction machine to have cations, a conveying belt below the paper suction machine is in contact with the anion releaser, the conveying belt is enabled to have anions, the paper with the cations is sucked onto the conveying belt through the anions on the conveying belt, and then the cations on the paper are neutralized through the anions. Then the paper is conveyed to a printer through a conveyor belt for printing, and after the paper is put down by the paper suction machine, the air cylinder pulls the paper suction machine to move back to the upper part of the box body for continuously sucking the paper.
When the paper suction machine sucks two pieces of paper, the air cylinder works to push the paper suction machine to move towards the printing machine along the slide rail until the paper suction machine is contacted with a switch for controlling the cation releaser, at the moment, the cation releaser is electrified to release cations so that the two pieces of paper carry the cations at the same time, according to the principle that like poles repel each other, the lower paper is actively dropped on the conveying belt under the repulsive force of the upper paper and the attractive force of anions on the conveying belt, and then the cations on the lower paper are neutralized through the anions on the conveying belt, so that the lower paper is uncharged. The upper paper is attracted to the conveyor belt by the suction of anions on the conveyor belt, while cations on the upper paper are neutralized. Then, the paper on the conveying belt enters a printing machine for printing through the conveying of the conveying belt, and after the paper is put down by the paper suction machine, the air cylinder pulls the paper suction machine to move back to the upper part of the box body in a return way so as to continuously suck the paper.
