Abstract
The utility model discloses a printer, which comprises a printing head and a paper feeding table corresponding to the printing head. An upper paper feeding roll is arranged on the upper part of the paper feeding table, a lower paper feeding roll is arranged on the lower part of the paper feeding table, the upper paper feeding roll and the lower paper feeding roll are contacted and mated, at least two separation pieces are arranged on the paper feeding table, an open groove is formed between two separation pieces, and the upper paper feeding roll and the lower paper feeding roll are contacted and mated at the open groove. According to the printer disclosed by the utility model, paper jam of the printer can be effectively avoided, and the waste of printing paper and the damage to the printer can be lessened.
Description
Technical field
The utility model relates to a kind of printer.
Background technology
Be equipped with paper advance mechanism in the existing printer, its structure mainly comprises transport roller and lower transport roller, and upper transport roller contacts cooperation with lower transport roller, and printing paper is clamped, and drives printing paper when upper transport roller and lower transport roller rotate and advances.
As everyone knows, upper transport roller and lower transport roller are cylindrical, and printing paper slightly has distortion or bending, just might enter in the slit between lower transport roller and the paper feed platform and cause paperboard, have both caused printing paper to waste, and can shorten again the service life of printer.
Summary of the invention
Based on this, the utility model is to overcome the defective of prior art, and a kind of printer is provided, and the utility model can effectively be avoided the printer paperboard, reduces the waste of printing paper and the damage of printer.
Its technical scheme is as follows:
A kind of printer, comprise printhead and the paper feed platform corresponding with printhead, be provided with transport roller on the top of paper feed platform, be provided with lower transport roller in the bottom of paper feed platform, upper transport roller contacts cooperation with lower transport roller, be provided with at least two partitions at the paper feed platform, form fluting between two partitions, described upper transport roller contacts cooperation with lower transport roller at this fluting place.
The below describes further technical scheme:
Described paper feed platform comprises the first platform and the second platform, is provided with contraposition at the first platform and lacks, and described partition is located on the second platform, and partition stretches in contraposition lacks.
Described upper transport roller is cylindric, and described lower transport roller is provided with at least two axle journals, and described partition is positioned at axle journal.
The below describes advantage or the principle of aforementioned techniques scheme:
1, owing to be provided with partition at the paper feed platform, form fluting between the partition, upper transport roller contacts at this fluting place to cooperate and drive printing paper with lower transport roller and advances, and partition can stop the printing paper last volume and snap in printer; The waste of printing paper and the damage of printer have been reduced;
2, the paper feed platform is formed by the first platform and the docking of the second platform, processes and install more convenient;
3, lower transport roller is provided with a plurality of axle journals, and this axle journal can be stepped down to partition.

The specific embodiment
The below is elaborated to embodiment of the present utility model:
Extremely shown in Figure 5 such as Fig. 1, a kind of printer, comprise printhead 10 and the paper feed platform 20 corresponding with printhead 10, be provided with transport roller 30 on the top of paper feed platform 20, be provided with lower transport roller 40 in the bottom of paper feed platform 20, upper transport roller 30 contacts cooperation with lower transport roller 40, is provided with at least two partitions 221 at paper feed platform 20, form fluting 222 between two partitions 221, described upper transport roller 30 contacts cooperation with lower transport roller 40 at these 222 places that slot.
Wherein, described paper feed platform 20 comprises the first platform 21 and the second platform 22, is provided with contraposition at the first platform 21 and lacks 211, and described partition 221 is located on the second platform 22, and partition 221 stretches into contraposition and lacks in 211.Described upper transport roller 30 is cylindric, and described lower transport roller 40 is provided with at least two axle journals 41, and described partition 221 is positioned at axle journal 41.
Present embodiment has following advantage:
1, owing to be provided with partition 221 at paper feed platform 20, form fluting 222 between the partition 221, upper transport roller 30 contacts at these 222 places that slot to cooperate and drive printing paper with lower transport roller 40 and advances, and partition 221 can stop the printing paper last volume and snap in printer; The waste of printing paper and the damage of printer have been reduced;
2, paper feed platform 20 is formed by the first platform 21 and 22 docking of the second platform, processes and install more convenient;
3, lower transport roller 40 is provided with a plurality of axle journals 41, and this axle journal 41 can be stepped down to partition 221.
The above embodiment has only expressed the specific embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
