DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figure 1-Figure 5 A device for capturing image text information includes a panel 1, a bracket 2 installed on the panel 1, and a scanning head 3 installed on the bracket 2. The scanning head 3 is located directly above the panel 1. The upper surface of the panel 1 is connected with a conveying mechanism and a moving mechanism. The output end of the conveying mechanism is connected with a conveyor belt 5. The conveyor belt 5 is located directly below the scanning head 3. The output end of the moving mechanism is connected with two clamping assemblies. The other ends of the two clamping assemblies are both against the upper surface of the conveyor belt 5.

[0024] The device for capturing image and text information in the utility model is similar in structure to the existing device for capturing image and text information, such as the high-speed camera model E3318. Figures 1 to 5As shown, when the device for capturing image text information in the utility model scans text or patterns on a paper placed on a panel 1 through a scanning head 3, if the paper is long, first manually rotate the two clamping components toward the panel 1 until the clamping components are tightly attached to the paper above the conveyor belt 5 and then stop, then turn on the switch of the moving mechanism through the internal controller of the bracket 2, and the moving mechanism is started, which will move the two clamping components to both sides, so that the warped paper can be flattened on the surface of the conveyor belt 5, which can not only increase the scanning effect, but also increase the contact area between the conveyor belt 5 and the paper, thereby increasing the friction between the conveyor belt 5 and the paper, and then turn on the conveying mechanism through the controller again. After the conveying mechanism is started, the output end will drive the conveyor belt 5 to move, and when the conveyor belt 5 moves, the paper on its surface will passively move with the conveyor belt 5 due to the friction, so that another part of the paper can be moved to the bottom of the scanning head 3, and then subsequent scanning can be performed. In addition, in the above manner, the scanning can be completed automatically without manually pushing the paper, which is convenient and fast.

[0025] It should be noted here that the internal controller of the bracket 2 is a very mature technology at present, so it will not be described in detail.

[0026] Please refer to Figure 2 A conveying cavity 101, a moving cavity 103 and two motor cavities 102 are provided on the upper surface of the panel 1. The moving mechanism is located in the moving cavity 103 and one of the motor cavities 102, and the conveying mechanism is located in the conveying cavity 101 and the other motor cavity 102.

[0027] More specifically, by providing the conveying chamber 101, the moving chamber 103 and the two motor chambers 102, the moving mechanism and the conveying mechanism can be accommodated to avoid occupying external space.

[0028] Please refer to Figure 1 , Figure 3 and Figure 5 The moving mechanism includes a moving motor 6 and a bidirectional screw rod 9. The outer wall of the moving motor 6 is fixedly connected to the inner wall of one of the motor cavities 102. The output shaft of the moving motor 6 is fixedly connected to one end of the bidirectional screw rod 9. The other end of the bidirectional screw rod 9 passes through the motor cavity 102, the moving cavity 103 and two clamping assemblies, and is rotatably connected to the inner wall of the moving cavity 103.

[0029] More specifically, when it is necessary to flatten the paper on the panel 1, it is only necessary to turn on the switch of the movable motor 6 through the internal controller of the bracket 2. The output shaft of the movable motor 6 drives the bidirectional screw rod 9 to rotate. As the bidirectional screw rod 9 rotates, the two clamping components connected to the surface can be driven to move to both sides, so that the paper on the panel 1 can be flattened to both sides.

[0030] Please refer to Figure 1 , Figure 3 and Figure 5 The clamping assembly includes a moving block 7 and a caressing plate 8. The lower end of the moving block 7 is sleeved and threadedly connected to the outer wall of the bidirectional screw 9. The other end of the moving block 7 is connected to one end of the caressing plate 8. The bottom surface of the other end of the caressing plate 8 is against the upper surface of the conveyor belt 5.

[0031] More specifically, when placing a paper on the panel 1, the smoothing plate 8 can be erected first, and then the paper can be placed on the panel 1, and then the moving block 7 can be rotated downward to press the paper onto the conveyor belt 5; at this time, the paper may be warped on both sides, affecting the scanning effect. When the bidirectional screw 9 rotates, the moving block 7 moves passively, which can drive the smoothing plate 8 to move, so that the paper can be flattened on both sides to avoid warping.

[0032] The moving block 7 and the caressing plate 8 are close to each other and are rotationally connected through a damping shaft.

[0033] More specifically, by providing a damping shaft, not only can the caressing plate 8 be rotated as required, but also after the caressing plate 8 is turned down, the paper below can be limited to a certain extent by the characteristics of the damping shaft.

[0034] Please refer to Figure 5 A rolling cavity 801 is provided on one side of the smoothing plate 8 close to the conveyor belt 5 , and a smoothing rod 11 is rotatably connected to the inner wall of the rolling cavity 801 , and the outer wall of the smoothing rod 11 abuts against the upper surface of the conveyor belt 5 .

[0035] More specifically, by providing the rolling chamber 801 and the smoothing rod 11, the paper can be flattened and the friction between the smoothing plate 8 and the paper can be reduced. When the conveyor belt 5 rotates and the paper moves, the smoothing rod 11 will slide on the surface of the paper and will not hinder the movement of the paper.

[0036] Please refer to Figure 1 , Figure 3 and Figure 4 The conveying mechanism includes a conveying motor 4 and two transmission rods 10. The outer wall of the conveying motor 4 is fixedly connected to the inner wall of another motor cavity 102. The output shaft of the conveying motor 4 is fixedly connected to one end of one of the transmission rods 10. The two transmission rods 10 are arranged in parallel, and both ends of the two transmission rods 10 are rotatably connected to the inner wall of the conveying cavity 101. The two transmission rods 10 are respectively located at both ends of the conveyor belt 5, and both roll against the inner wall of the conveyor belt 5.

[0037] More specifically, when it is necessary to control the movement of the conveyor belt 5, it is only necessary to turn on the switch of the conveying motor 4 through the controller. After the output shaft of the conveying motor 4 rotates, it can drive the connected transmission rod 10 to rotate, so that it can cooperate with another transmission rod 10 at both ends of the conveyor belt 5 to drive the conveyor belt 5 to rotate.

[0038] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
