Abstract

The invention relates to a paper feeding device capable of conducting two-way paper flattening. The paper feeding device comprises a paper transmission device, a drive device, a negative pressure device and an air blowing device. The paper transmission device comprises a conveyor belt, a first drive wheel and a second drive wheel. The conveyor belt surrounds the first drive wheel and the second drive wheel. The first drive wheel and the second drive wheel drive the conveyor belt to rotate. The drive device is arranged on one side of the first drive wheel. An output shaft of the drive device is linked with the first drive wheel. The negative pressure device comprises a negative pressure draught fan, a negative pressure pipeline and a negative pressure port. The suction opening of the negative pressure draught fan is communicated with one end of the negative pressure pipeline. The other end of the negative pressure pipeline is communicated with the negative pressure port. The negative pressure port is fixedly arranged on the inner side of the conveyor belt. The opening of the negative pressure port is upwards. A plurality of vent holes are formed in the conveyor belt. The air blowing device is arranged above the conveyor belt. The air blowing opening of the air blowing device is downwards. As paper is flattened through air blowing and negative pressure, the paper can be laid on the conveyor belt more flatly, and the printing quality can be improved.

Description

technical field [0001] The invention relates to the technical field of printing machinery, in particular to a paper feeding device for two-way flattening paper. Background technique [0002] In the commonly used paper feeding device of the printing machine, the paper needs to be sent to the paper inlet through the transmission device. During the transmission process, the paper is required to be laid flat on the conveyor belt after it is lowered to the conveyor belt. However, due to the elasticity and flatness of the paper , or environmental influences, the paper may not fit properly, such as the end of the paper is upturned, the middle is raised, etc. Due to the height restriction of the paper inlet at the end of the belt, if the paper is warped or raised, it may cause paper feeding obstacles. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a paper feeding device that flattens the paper by blowing air and negati...
