DETAILED DESCRIPTION OF THE EMBODIMENTS

The embodiments of the present utility model are given for the purpose of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations will be obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

[0017] Embodiment: Please refer to Figure 1 - Figure 4 The present utility model provides a technical solution: A paper flattening device for document scanning, comprising: a triangular base 1; a placement plate 2, the outer wall of the placement plate 2 is fixedly connected to the outer wall of the triangular base 1; a windproof cover 3, the outer wall of the bottom of the windproof cover 3 is fixedly connected to the outer wall of the top of the triangular base 1; a flattening device 4, the outer wall of the flattening device 4 is fixedly connected to the outer wall of the windproof cover 3; a conveying device 5, the outer wall of the conveying device 5 is rotatably connected to the outer wall of the triangular base 1; the flattening device 4 includes a servo motor 41, the output end of the servo motor 41 is fixedly connected to a drive shaft 42, a slider 43 is slidably connected to the inner wall of the drive shaft 42, a bidirectional telescopic rod 44 is fixedly connected to the outer wall of the slider 43, a compression spring 45 is arranged outside the bidirectional telescopic rod 44, a connecting rod 46 is rotatably connected to the outer wall of the slider 43, one end of the connecting rod 46 away from the slider 43 is rotatably connected to a connecting ring 47, and a flattening roller 48 is rotatably connected to the inner wall of the connecting ring 47. Start the servo motor 41 to drive the drive shaft 42 to rotate slowly. During the rotation, the flattening roller 48 will contact the document. Due to the extrusion of the document, at this time, the flattening roller 48 flattens the document through the extrusion force and approaches the drive shaft 42 at the same time. During this process, the connecting rings 47 at both ends of the flattening roller 48 will transmit the force to the slider 43 through the connecting rod 46. At this time, the sliders 43 in the drive shaft 42 will approach each other under the force, and at this time, both ends of the compression spring 45 and the bidirectional telescopic rod 44 will be squeezed at the same time. At this time, the compression spring 45 is squeezed and contracts, and the bidirectional telescopic rod 44 shortens synchronously. The compression spring 45 provides a certain elastic restoring force on the one hand, and plays a buffering and stabilizing role during the sliding of the slider 43 on the other hand. The setting of the bidirectional telescopic rod 44 makes the movement of the flattening roller 48 more stable, and at the same time, the force is transmitted back to the flattening roller 48 along the original path through the reaction force, so that the flattening roller 48 has both a movable stroke and can stably flatten the document.

[0018] A guiding triangular strip 6 is fixedly connected to the inner side wall of the windproof cover 3. Both ends of the compression spring 45 are fixedly connected to the outer wall of the slider 43. One end of the drive shaft 42 away from the servo motor 41 is rotatably connected to the inner wall of the windproof cover 3. The outer wall of the servo motor 41 is fixedly connected to the outer wall of the windproof cover 3.

[0019] The conveying device 5 includes a support frame 51. The outer wall of the top of the support frame 51 is fixedly connected with a DC motor 52. The output end of the DC motor 52 is fixedly connected with a driving rod 53. The outer wall of the driving rod 53 is rollingly connected with a conveyor belt 54. The outer wall of the conveyor belt 54 is rollingly connected with a tensioning roller 55. The outer wall of the driving rod 53 is rollingly connected with a transmission belt 56. The outer wall of the transmission belt 56 is rollingly connected with a flattening roller 57. After the flattening is completed, the DC motor 52 on the support frame 51 is started. The DC motor 52 is symmetrically arranged on the driving rod 53, so that the driving rod 53 can obtain a stable rotational force. At this time, the rotating driving rod 53 rotates. Among them, the driving rod 53 drives the conveyor belt 54 to move so that the paper can be stably transported.

[0020] The outer wall of the tensioning roller 55 and the outer wall of the driving rod 53 are both rotatably connected to the inner wall of the triangular base 1. The outer wall of the support frame 51 is fixedly connected to the outer wall of the triangular base 1. The side wall of the conveyor belt 54 is slidably connected to the inner wall of the triangular base 1. The two ends of the flattening roller 57 are rotatably connected to the inner wall of the windproof cover 3. The paper flattened by the flattening roller 48 has been attached to the top of the triangular base 1. Therefore, under the conveyance of the conveyor belt 54, the paper can easily pass through the guiding triangular strip 6 and move towards the flattening roller 57. At the same time, the driving rod 53 also drives the flattening roller 57 to rotate through the transmission belt 56. The paper conveyed by the conveyor belt 54 will be flattened again by the flattening roller 57 to ensure the complete flattening of the document and reduce the time of repeated operations.

[0021] Working principle:

[0022] During use, first, the document placed on the placement board 2 is pushed into the gap between the triangular base 1 of the windproof cover 3. Since the edge of the document is warped at this time, it is blocked after sliding to the position of the guiding triangular strip 6 and then stops moving. The flattening device 4 is activated to flatten the document. At this time, the servo motor 41 is started to drive the driving shaft 42 to rotate slowly. During the rotation, the flattening roller 48 will come into contact with the document. Due to the extrusion of the document, the flattening roller 48 flattens the document through the extrusion force and approaches the driving shaft 42 at the same time. During this process, the connecting rings 47 at both ends of the flattening roller 48 will transmit the force to the slider 43 through the connecting rod 46. At this time, the sliders 43 in the driving shaft 42 will approach each other under the force. At this time, both ends of the compression spring 45 and the double telescopic rod 44 will be squeezed at the same time. At this time, the compression spring 45 is squeezed and contracts, and the double telescopic rod 44 shortens synchronously. The compression spring 45 provides a certain elastic restoring force on the one hand, and plays a buffering and stabilizing role during the sliding of the slider 43 on the other hand. The setting of the double telescopic rod 44 makes the movement of the flattening roller 48 more stable. At the same time, through the reaction force, the force is transmitted back to the flattening roller 48 along the original path, so that the flattening roller 48 has a movable stroke and can also flatten the document stably, so as to adapt to papers of different thicknesses. The flattening roller 48 flattens the paper during the movement process. Through continuous rolling and extrusion, the wrinkles on the paper are flattened, providing a flat paper surface for document scanning. When the driving shaft 42 squeezes the flattening roller 48 that presses the document away during the rotation, the slider 43 is connected to the connecting ring 47 through the connecting rod 46. The compression spring 45 and the double telescopic rod 44 push the slider 43 to both ends. At this time, the slider 43 moves, and the connecting rod 46 drives the connecting ring 47 to move, thereby making the flattening roller 48 move away from the driving shaft 42. At the same time, to prevent the stroke from being too long and hitting the windproof cover 3 during the moving away process, a square block is provided on the connecting ring 47 to limit the moving distance of the flattening roller 48.

[0023] After the flattening is completed, the DC motor 52 on the support frame 51 starts. The DC motors 52 are symmetrically arranged on the driving rod 53, enabling the driving rod 53 to obtain a stable rotational force. At this time, the rotating driving rod 53 rotates. The driving rod 53 drives the conveyor belt 54 to move, allowing the paper to be transported stably. The conveyor belt 54 is used to transport the paper and simultaneously drives the tension roller 55 to rotate. The function of setting the tension roller 55 is to maintain the tension of the conveyor belt 54 and prevent the conveyor belt 54 from loosening, thereby ensuring that the paper can move stably on the conveyor belt 54. At this time, the paper flattened by the flattening roller 48 has already adhered to the top of the triangular base 1. Therefore, under the transportation of the conveyor belt 54, the paper can easily pass through the guiding triangular strip 6 and move towards the flattening roller 57. At the same time, the driving rod 53 also drives the flattening roller 57 to rotate through the transmission belt 56. The paper conveyed by the conveyor belt 54 will be flattened again by the flattening roller 57 to ensure the complete flattening of the document and reduce the time for repeated operations. The tension roller 55 in the conveying device 5 ensures the tension of the conveyor belt 54 and improves the stability of paper transportation. The flattening roller 57 performs secondary flattening on the paper during the transportation process, improving the overall flattening efficiency.
