Abstract

Disclosed is a medium control mechanism, wherein a medium is arranged on a first medium support roller and a second medium roller, centers of two ends of the medium are mounted on a sliding sleeve which is sleeved on a column, the lower of the column is provided with a fixed central shaft, the central shaft is provided with a X-shaped device which ends are arranged on the first medium support roller and the second medium roller and are pressed against the first medium support roller and the second medium roller, by a compressing device, and friction coefficients of the X-shaped device ends and the first medium support roller and the second medium roller are less than a presetting value. The invention also discloses an inkjet printer, wherein two ends of each volume medium of the inkjet printer are provided with the medium control mechanism symmetrically, the mediums are limited at fixed positions by the medium control mechanism, and the X-shaped device and the compressing device are arranged between the first medium support roller and the second medium roller, so that the weight and volume of the printer are all reduced.

Description

technical field [0001] The invention relates to the technical field of medium control, in particular to a medium control mechanism and an inkjet printer. Background technique [0002] Most of the roll materials of large inkjet printers are installed on two rotatable cloth rollers, refer to Figure 1a -c, is a schematic diagram of the installation position of the medium in the prior art, where Figure 1a , Figure 1b , Figure 1c All three are of the same size. Media 1 is placed on fabric rollers 2 and 3, see Figure 1a , the medium 1 is affected by the feeding force F and the weight W1, when the printing work starts, there are more medium 1 and the weight is heavier, and the printing work can run relatively smoothly. After working for a period of time, the material becomes thinner and the weight becomes lighter as W2, such as Figure 1b As shown, under the action of the feeding force F, the medium 1 may be pulled out from the gap formed by the two rotatable cloth rest...
