Description

Paper separating device Technical Field The utility model relates to the technical field of printer paper separation, in particular to a paper separation device. Background The paper separating device is an important part for ensuring that paper can accurately enter a printing channel one by one in a printer, and paper is separated when the printer feeds paper through matching of a paper rubbing wheel and a paging device. After the existing paper separating device is used for a period of time, due to the fact that the springs and the paging devices are used for extruding paper and matching the paper rubbing wheels to separate the paper, the rubber sleeves on the surfaces of the paper rubbing wheels are inevitably worn out with the paper to a large extent, once the rubber sleeves of the traditional paper rubbing wheels are worn out to a certain extent, the distance between the paper rubbing wheels and the paper is too large, a series of problems that paper cannot be fed and the like occur, the rubber sleeves need to be replaced in time to be used normally, and the paper separating device is very troublesome. Disclosure of utility model In view of the above problems, the present application has been made to provide a sheet separating apparatus that overcomes the problems or at least partially solves the problems set forth in the background art. The embodiment of the application provides a paper separating device, which comprises a printer and a paging device, wherein the paging device is arranged in the printer; The paper rubbing wheel is rotatably arranged in the printer, a rubber sleeve is arranged on the outer side of the paper rubbing wheel, and air holes communicated with the inside of the rubber sleeve are formed in the surfaces of the rubber sleeve and the paper rubbing wheel; The supporting tube is slidably arranged in the printer, one end of the supporting tube extends into the paper rubbing wheel, and the supporting tube is communicated with the inside of the paper rubbing wheel; The elastic compensation unit comprises a spring sleeved on the outer side of the support tube, one end of the spring is abutted against the fixed shell, and the other end of the spring is abutted against the support plate fixedly connected with the support tube; The negative pressure adsorption unit comprises a powerful fan arranged on the printer and a shaft sleeve communicated with the supporting tube, wherein the powerful fan is communicated with the supporting tube through the shaft sleeve, and when the fan is started, negative pressure is generated at an air hole on the surface of the paper rubbing wheel to adsorb paper.
