[0016] A method for intelligently adjusting a scanning drive of a film digitizing scanning system comprises the following steps:

[0017] S1: The film to be scanned is fed from the front end of the conical input sleeve. The power is turned on. The infrared sensor probe installed on the inner side of the front end of the conical input sleeve senses the film and simultaneously starts the two transmission motors. Under the support of the mounting frame, the transmission motors drive the two transmission shafts to rotate in opposite directions. Then, the transmission shafts drive the silicone layer to rotate through the feeding wheel to transport the film horizontally.

[0018] S2: The support frame and the guide column are slidably connected via a support spring, and one end of the guide column passes through the support frame and the support spring and is fixedly connected to the mounting frame, so that the mounting frame maintains a close fit between the two adjacent silicone layers and the film under the elastic support of the support spring through the guide column, and maintains a stable driving of the film by the feed wheel through the silicone layer;

[0019] S3: The material box is connected to the conical input sleeve and the conical discharge sleeve through a material guide trough. The material guide trough facilitates the input and output of the film inside the material box. Two elastic pressure plates are used to press the film tightly to keep it in close contact with the upper end surface of the transparent carrier. Then, a scanning camera is used to perform a preliminary scan of the edge of the film to ensure that the film is accurately positioned under the drive of the feed wheel, thereby improving the accuracy of subsequent digitization.

[0020] S4: A plurality of lamp beads are provided on the upper end surface of the light board, so that the light board emits light in an array through the lamp beads and evenly fills the film with light through the filter and the transparent carrier, so that the plurality of scanning cameras can further scan the film through the lens under the support of the mounting sleeve and transmit the image information to the circuit board provided in the electrical box, and then the image information can be converted into digital form through the circuit board;

[0021] S5: The protective box, material box and light-shielding cover can prevent the scanning camera from being affected by external light when scanning the film. By rotating the adjustment knob, the adjustment knob can synchronously drive multiple lenses to slide vertically at the bottom end of the mounting sleeve through the connecting plate, thereby realizing the adjustment of the focal length of the scanning camera.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention senses the film through an infrared sensing probe provided on the inner side of the front end of the conical input sleeve. The transmission motor drives two transmission shafts to rotate in opposite directions. Then, the transmission shaft drives the silicone layer to rotate through the paddle wheel, which can transport the film horizontally. The mounting frame maintains the close fit of the two adjacent silicone layers and the film under the elastic support of the support spring through the guide column, and maintains the stable driving of the film by the paddle wheel through the silicone layer. The film is pressed tightly by two elastic pressing sheets, and the film is kept in close fit with the upper end surface of the transparent carrier. Then, the edge of the film is preliminarily scanned by the scanning camera to ensure that the film is accurately positioned under the driving action of the paddle wheel, thereby improving the accuracy of subsequent digitization.

[0024] 2. The present invention uses the array of lamp beads on the light board to emit light and uses filters and transparent carriers to evenly fill in the light for the film, so that multiple scanning cameras can further scan the film through the lens under the support of the mounting sleeve and transmit the image information to the circuit board provided inside the electrical box, and then the image information can be converted into digital form through the circuit board. The protective box, the material box and the light-shielding cover can prevent the scanning camera from being affected by external light when scanning the film. When the adjustment knob is rotated, the connecting plate synchronously drives the multiple lenses to slide vertically at the bottom end of the mounting sleeve, thereby realizing the control of the focal length of the scanning camera.

7. A scanning driving method for an intelligently adjusting film digitizing scanning system according to claim 6, characterized in that: The following steps are involved: S1: The film to be scanned is fed progressively from the front end of the conical input sleeve (201), the power is turned on, the film is sensed by the infrared sensing probe provided on the inner side of the front end of the conical input sleeve (201), and two transmission motors (206) are started synchronously, so that the transmission motors (206) drive two transmission shafts (210) to rotate in opposite directions under the support of the mounting frame (207), and then the transmission shafts (210) drive the silicone layer (208) to rotate through the feeding wheel (209), so that the film can be transported horizontally; S2: The support frame (211) and the guide column (212) are slidably connected via the support spring (213), and one end of the guide column (212) passes through the support frame (211) and the support spring (213) and is fixedly connected to the mounting frame (207), so that the mounting frame (207) maintains the close fit between the two adjacent silicone layers (208) and the film under the elastic support of the support spring (213) through the guide column (212), and maintains the stable driving of the film by the paddle wheel (209) through the silicone layer (208); S3: The material box (401) is connected to the conical input sleeve (201) and the conical discharge sleeve (106) through the material guide trough (405). The material guide trough (405) facilitates the input and output of the negative film inside the material box (401). The two elastic pressing pieces (404) facilitate the pressing of the negative film to keep the negative film and the upper end surface of the transparent carrier film (402) in close contact. Then, the edge of the negative film is preliminarily scanned by the scanning camera (306) to ensure that the negative film is accurately positioned under the driving action of the feeding wheel (209), thereby improving the accuracy of subsequent digitization. S4: A plurality of lamp beads are provided on the upper end surface of the lamp board (107), so that the lamp board (107) emits light in an array through the lamp beads and evenly fills the film with light through the filter (108) and the transparent carrier (402), so that the plurality of scanning cameras (306) can further scan the film through the lens (305) under the support of the mounting sleeve (303) and transmit the image information to the circuit board provided inside the electrical box (301), and then the image information can be converted into digital form through the circuit board; S5: The protective box (102), the material box (401) and the light shielding sleeve (403) can keep the scanning camera (306) from being affected by external light when scanning the film, and the adjusting knob (302) is rotated so that the adjusting knob (302) synchronously drives the multiple lenses (305) to slide vertically at the bottom end of the mounting sleeve (303) through the connecting plate (304), thereby achieving the adjustment of the focal length of the scanning camera (306).
