Abstract
The utility model relates to a novel revolution roller comprising a mandrel, a sponge sleeve and a gear sleeve, wherein the sponge sleeve is arranged on one end of the mandrel and the gear sleeve is arranged on the other end of the mandrel. The gear sleeve arranged on one end of the mandrel enables the revolution roller to perform forward and reverse rotation when in use so that two-sided printing or copying of a printer is enabled, no man is needed for replacing paper, and the revolution roller is more convenient to use and more humane.
Description
Technical field
The utility model relates to a kind of revolving roll, relates in particular to a kind of printer duplex printing or duplicating novel rotation roller.
Background technology
Along with the arrival of information revolution, computer has obtained using widely in world's all trades and professions, and printer namely is one of topmost output equipment of various computers, and it can record main frame operation result, mimeograph documents copy, make form and generating writing pattern.Though this year, the development speed of printer was very fast, various types of printers are come out one after another, as wire-dot printer, ink jet type, heat-sensitive type, electromechanical, laser type etc., its printing function all is that single face is printed, namely the one side at paper prints character and figure, another side is wasted, and causes very big waste.On the other hand, duplex printing if desired then needs the positive and negative of artificial conversion paper, increases labour intensity, also the efficient printed of influence.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, and a kind of printer duplex printing or duplicating novel rotation roller are provided.
The technical scheme that realizes the utility model purpose is: a kind of novel rotation roller, comprise mandrel, sponges cover and geared sleeve, and described sponges cover is arranged at an end of mandrel, and described geared sleeve is arranged at the other end of mandrel.
Further, described mandrel is the plastics mandrel.
Further, described mandrel is hollow circular cylinder shape mandrel, and circle one end is provided with boss in the described mandrel.
Further, described geared sleeve is plastic gear.
Further, described geared sleeve and described mandrel are one-body molded.
Further, also be provided with plastic septum between described sponges cover and the described geared sleeve.
Further, described plastic septum and mandrel are one-body molded.
The utlity model has positive effect: an end of mandrel is provided with geared sleeve, can rotating during use, thus realize printer duplex printing or duplicating, do not need manually to change paper, more convenient to use, also hommization more.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail below, wherein:
Fig. 1 is structural representation of the present utility model.
Wherein: 1, mandrel, 2, geared sleeve, 3, plastic septum, 4, sponges cover.
The specific embodiment
As shown in Figure 1, the utlity model has a kind of novel rotation roller, comprise mandrel 1, sponges cover 4 and geared sleeve 2, sponges cover 4 is arranged at an end of mandrel 1, and geared sleeve 2 is arranged at the other end of mandrel 1.
In above-described embodiment 1, an end of mandrel 1 is provided with geared sleeve 2, can rotating during use, thus realize printer duplex printing or duplicating, do not need manually to change paper, more convenient to use, also hommization more.
All the other are identical with embodiment 1, and difference is that mandrel 1 is the plastics mandrel, and geared sleeve 2 is plastic gear, and mandrel 1 is hollow circular cylinder shape mandrel, and circle one end is provided with boss in the mandrel 1, and geared sleeve 2 is one-body molded with mandrel 1.
In above-described embodiment 2, plastics mandrel, plastic gear cost are low, and one-body molded processing is simple, and circle one end is provided with boss and can effectively prevents from skidding when mandrel 1 from rotating in the mandrel 1, and is convenient.
All the other are identical with embodiment 1 or 2, and difference is, also is provided with plastic septum 3 between sponges cover 4 and the geared sleeve 2, and plastic septum 3 is one-body molded with mandrel 1.
In above-described embodiment 3, increase the contact that plastic septum 3 can be avoided miscellaneous part, avoid influencing duty, guarantee operating efficiency.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
