Problems solved by technology
[0003] The problem of this conveying mechanism is that in the printing process, under the driving of the roller 22, the printing medium is easy to pass through the second passage plate 16 with the opening 161 for the roller on the second passage plate 16, and is wound around the roller. 22, because the printing device cannot detect the blockage of the printing medium in time, which causes equipment failure of the printing device, and the reliability is poor
In the conveying mechanism, if there is a gap between the roller and the end of the channel plate forming the conveying channel, the above problems may also occur

The invention provides a conveying mechanism and a printing device. The conveying mechanism comprises a conveying channel and a roller, wherein the conveying channel comprises channel plates; a clearance is reserved between the roller and the channel plates; part of the roller is located in the conveying channel; the conveying mechanism further comprises a detection plate and a sensor; the detection plate and the roller are located on the same side of the conveying channel, and are oppositely arranged at an interval; and the detection plate is used for moving to trigger the sensor when a printing medium is stuffed between the detection plate and the roller. Compared with the prior art, the conveying mechanism and the printing device can immediately detect a paper stuffing problem, prevent equipment failures caused by the reason that the printing medium is wound on the roller, and therefore, are high in reliability.
Description
technical field [0001] The invention relates to a conveying mechanism and a printing device. Background technique [0002] like figure 1 As shown, a common printing device includes a conveying mechanism and a printing mechanism, wherein the conveying mechanism includes a conveying channel and a roller 22 for driving the printing medium to move along the conveying channel, and the conveying channel is composed of a first channel plate 15 and a second channel plate 15 arranged at a distance from each other. Two channel plates 16 are formed, and one end of the delivery channel communicates with the outlet P of the printing device; the printing mechanism includes a print head 211 arranged tangentially with the roller 22, wherein the print head 211 is located on one side of the first channel plate 15, and passes through The opening on the first channel plate 15 stretches into the conveying channel; the roller 22 is positioned at a side of the second channel plate 16, and stretch...
