Description

Label printing device Technical Field The utility model relates to the technical field of printing devices, in particular to a label printing device. Background The label is a brief label for marking information such as the name, weight, volume and use of the article, and comprises a traditional printed label and a modern bar code printed label, wherein the traditional printed label prints the information on the label through a printing device. When the existing printing device performs printing operation, label paper is conveyed into a printing machine by a discharging roller to be printed, and is rolled up by a collecting roller after printing is finished, so that the printing quality is ensured in order to keep a tensioning state when the label paper is printed, the label paper between the discharging roller and the collecting roller needs to be kept in a certain tensioning state, but in the later printing stage, the label paper on the discharging roller is gradually reduced, the label paper at the position is in a loose state and cannot be kept in the tensioning state, deviation is easily caused, and the printing quality is influenced. Disclosure of utility model The utility model aims to provide a label printing device which solves the problems in the background technology. The label printing device comprises a machine base, wherein one side of the top end of the machine base is rotatably provided with a discharging roller, the other side of the top end of the machine base is rotatably provided with a receiving roller, the top end of the machine base is provided with a printer and a drying box, the drying box is arranged on the outlet side of the printer, the drying box is internally provided with a drying mechanism, the printer and the drying box are arranged between the discharging roller and the receiving roller, a plurality of groups of material guiding mechanisms are arranged between the discharging roller and the printer and between the drying box and the receiving roller, each material guiding mechanism comprises a bracket and two material guiding rollers, the bracket is arranged on the top end of the machine base, and the two material guiding rollers are vertically rotatably arranged on the bracket. As the preference of this technical scheme, guide mechanism still include actuating mechanism, actuating mechanism drive guide roller slides from top to bottom on the support, realizes the adjustment of interval between two guide rollers. As the preference of this technical scheme, actuating mechanism include expansion bend, drive plate and connecting plate, the expansion bend is located support top or frame top, the drive plate is connected to the output of expansion bend, the axis of drive plate length is parallel with the axis of guide roller length, the both ends of drive plate set up the connecting plate, the connecting plate is connected with the roller of guide roller. As the preference of this technical scheme, the import side of printing machine is equipped with the exhaust mechanism that is used for cleaning label paper surface, and exhaust mechanism is including exhaust hood, tuber pipe, collecting box and the air exhauster that connect gradually, and the exhaust hood is located the top of the label paper of carrying, sets up filter screen I in the collecting box. As the preference of this technical scheme, stoving mechanism include bellows, axial fan and heating pipe, the upper and lower end opening of bellows just connects on the roof in the stoving case, the roof that the stoving case is located in the bellows sets up the opening, sets up filter screen II in the opening, axial fan and heating pipe locate in the bellows from top to bottom, axial fan's air inlet end is towards filter screen II, axial fan's air-out end is towards the heating pipe. Compared with the prior art, the automatic label paper feeding device has the beneficial effects that the multiple groups of the material guiding mechanisms are arranged, the material guiding mechanisms comprise the support and the two material guiding rollers, the two material guiding rollers are arranged on the support in a vertical rotating mode, when label paper is conveyed, the distance between the two material guiding rollers passes, and friction force of the two material guiding rollers on the label paper enables the conveyed label paper to be kept in a tensioning state when the label paper of the discharging rollers is gradually reduced, the label paper is kept straight, and good printing quality is kept.
