Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
A paper scanning device shown in fig. 1 and 2 includes a central controller, and a paper feeding device, a scanning device, a sensing device and a transparent scanning platform 1 which are respectively in communication connection with the central controller, wherein the paper feeding device includes a conveying device for conveying paper to the scanning platform 1, sensing devices for sensing the position of the paper on the scanning platform 1 are respectively arranged on two sides of the scanning platform 1, and the scanning device is arranged above and below the scanning platform 1.
The principle of the paper scanning device provided by the invention is as follows:
the conveying device under the control of the central controller firstly conveys paper to the scanning platform 1, and the scanning platform 1 is transparent, so that after the sensing devices positioned at two sides of the scanning platform sense the paper, the central controller controls the scanning devices respectively positioned above and below the scanning platform 1 to respectively scan the front and the back of the paper and transmit the paper to the central controller.
In this embodiment, lighting devices 2 are installed on both sides above scanning platform 1, and lighting devices 2 are installed on both sides below scanning platform 1, wherein lighting devices 2 are preferably bar-shaped lighting lamps capable of covering whole scanning platform 1, and the bar-shaped lighting lamps on both sides of scanning platform 1 are arranged perpendicularly in opposite directions, so that paper on scanning platform 1 can be prevented from having shadows.
In this embodiment, the two sides of the scanning platform 1 are both provided with the pressing plates 3, and the sensing device comprises a first paper in-place sensor 4 arranged close to the conveying device and a second paper in-place sensor 5 arranged far away from the conveying device; wherein, the pressing plate 3 can press the paper fed into the scanning platform 1 by the paper feeding device, so that when the paper feeding device just feeds the paper onto the scanning platform 1, the paper in-place sensor one 4 close to the conveying device can sense the paper, the paper in-place sensor two 5 far away from the conveying device does not sense the paper, the scanning device does not start to operate, along with the paper feeding device further feeds the paper into the scanning platform 1, not only the paper in-place sensor one 4 close to the conveying device can sense the paper, but also the paper in-place sensor two 5 far away from the conveying device can sense the paper, the central controller receives signals of the paper in-place sensor one 4 and the paper in-place sensor two 5, and simultaneously the central controller also needs to receive signals of two groups of sensing devices respectively positioned on the pressing plates 3 at two sides of the scanning platform 1 to ensure the position of the paper on the scanning platform 1, then a signal is sent to stop the paper feeding of the paper feeding device and start the scanning of the scanning device, so that the front and the back of the paper on the scanning platform 1 are scanned simultaneously.
In this embodiment, two side edges of the scanning platform 1 are respectively provided with a baffle 6 parallel to the paper feeding direction of the paper feeding device; thus, the baffle 6 and the pressing plate 3 are matched with the paper feeding device, and the paper is guaranteed to be flat on the scanning platform 1 after the paper feeding device feeds the paper into the scanning platform 1.
In this embodiment, the ion wind power generation device further comprises an ion wind machine 7 located above the scanning platform 1, and a plurality of ion wind outlets 8 matched with the ion wind machine 7 are further arranged on the side edge of the scanning platform 1; before the scanning device scans, the central controller controls the ion fan 7 to blow out ion wind on the front surface of the paper on the scanning platform 1, and meanwhile, the ion wind outlet 8 on the side edge of the scanning platform 1 can suck away paper fragments blown out by the ion wind on the front surface of the paper; thus, a row of ion wind outlets 8 arranged in parallel can be arranged on the side of the scanning platform 1.
In this embodiment, the scanning device disposed right above the scanning platform 1 is a CCD camera 9, and the scanning device disposed right below the scanning platform 1 is a CCD camera 9; thus, the content of the front and back sides of the paper can be scanned and transmitted to the central controller through the CCD camera 9.
In this embodiment, the conveying device includes a conveying belt 12 driven by a conveying roller 11 driven by a transmission device 10, and a gap between a conveying belt pressing strip 13 and the conveying belt 12 above the conveying roller 11 is greater than or equal to a gap between the conveying belt pressing strip 13 and the conveying belt 12 above the scanning platform 1; in this way, it is possible to facilitate the paper that has just been transported by the transport device into the scanning platform 1 to enter the gap between the conveyor belt batten 13 and the conveyor belt 12 above the scanning platform 1.
In the embodiment, the conveyor belt pressing strips 13 and the conveyor belt 12 which are positioned above the scanning platform 1 are arranged in parallel; this ensures the flatness of the paper on the scanning platform 1.
In the present embodiment, the frictional force between the conveying belt 12 and the sheet is larger than the frictional force between the belt trim 13 and the sheet; thus, when the paper flows into the conveying belt 12, the paper is located between the conveying belt 12 and the conveying belt pressing strip 13, the conveying belt pressing strip 13 can generate a downward pressure on the paper, and the paper can be conveyed forwards along with the conveying belt 12 because the friction force between the paper and the conveying belt 12 is greater than the friction force between the paper and the conveying belt pressing strip 13.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, it should be noted that, for those skilled in the art, many modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
