[0035] A plurality of rollers 124 arranged longitudinally and rotating in the same direction are rotatably mounted on the housing 101. All rollers 124 are connected by belts 122. The rollers 124 are rotatably mounted on the housing 101. One of the rollers 124 is connected to the output shaft of a motor 123. The motor 123 is mounted on the housing 101. A gap is left between the rollers 124 and the housing 101 for the paper 3 to pass through.

[0036] There are three rollers 124 , and a baffle 118 and a guide long plate 112 are installed on the shell 101 . The baffle 118 is located between two rollers 124 close to the adjustment component. The guide long plate 112 is provided with an arc surface, and a sensor 111 is installed on the guide long plate 112 .

[0037] A stand 104 is mounted on the base 110 , and a wide-angle camera 105 and a fill light 106 are provided on the stand 104 ; a paper receiving tray 103 is mounted on the stand 104 .

[0038] The working principle of the present invention is as follows: the paper 3 is photographed by a wide-angle camera 105, and the photos taken at different positions are combined on the computer software to form a complete scan content. The fill light 106 compensates the light intensity of the scanned paper; the upper protective cover 102 protects the equipment.

[0039] The paper 3 is placed on the strip support plate 121 and the second strip tray 117. The wheels 109 support the first strip tray 108, making it smoother to pull the first strip tray 108. The spring 119 is compressed by pulling the slide 120. After the paper 3 is placed, the slide 120 is released. The slide 120 returns to its original position under the elastic force of the spring 119, pushing the paper 3 into an orderly arrangement. The strip tray 108 is pulled to place a larger paper 3. The strip tray 108 is pulled out to drive the strip support plate 121 to slide on the adjustment slide rail 107 and the second strip tray 117, driving the slide button 115 to slide on the strip support plate 121, driving the connecting rod 116 to swing, thereby lengthening the paper bin. The cross bars on the second strip tray 117, the first strip tray 108, and the strip support plate 121 ensure that the paper 3 remains flat, making it easier to scan larger paper 3.

[0040] The starting motor 123 drives one roller 124 to rotate, and the roller 124 drives the other rollers 124 to rotate through the belt 122; the starting hydraulic cylinder 201 drives the movable slide plate 202 to move, and the movable slide plate 202 drives the grooved guide plate 203 to rotate, and the grooved guide plate 203 drives the movable plate 206 to move in the "L"-shaped slide groove of the mounting plate 204, driving the long slide bar 205 to slide on the shell 101, and at the same time the movable plate 206 slides on the long slide bar 205, and the two movable plates 206 respectively drive a rack 207 to first move relative horizontally, and then move longitudinally. During longitudinal movement, the movable plate 206 drives the connecting plate 210 and the paper pushing rod 211 to move downward, and the second end of the paper pushing rod 211 contacts the paper 3. The movable plate 206 moves downward to compress the spring 209, and then the toothed structure on the rack 207 engages with the gear 208, driving the gear 208 to rotate, and the gear 208 drives the paper pushing rod 211 to rotate. The paper pushing rod 211 rotates to push the paper 3 toward the direction of the guide long plate 112, and the paper 3 contacts the arc surface on the guide long plate 112 and moves upward. The baffle 118 blocks and guides, and then the paper 3 contacts the rotating roller 124, and the roller 124 transports the paper 3 upward and sends it to the paper receiving tray 103. When the paper 3 is transferred, the sensor 111 detects that the transfer is completed, and the device enters the next scanning cycle.

[0041] When the paper feeding mechanism 2 completes the paper feeding action, the hydraulic cylinder 201 drives the movable plate 206 and the long slide bar 205 to reset, so that the paper pushing rod 211 leaves the upper surface of the paper 3 to avoid affecting the wide-angle camera 105 and the fill light 106 from photographing and scanning the paper 3.

[0042] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Those skilled in the art may modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present invention.
