A circuit board is provided inside the power connection box (301), and the circuit board is electrically connected to the plurality of scanning cameras (306).

10. A scanning driving method for an intelligent adjustable negative film digital scanning system according to any one of claims 1-9, characterized in that, It includes the following steps: S1: Feed the negative film to be scanned from the front end of the conical input sleeve plate (201). Connect the power supply. The infrared induction probe provided inside the front end of the conical input sleeve plate (201) senses the negative film and synchronously starts two driving motors (206), so that the driving motors (206) drive two of the transmission shafts (210) to rotate in opposite directions under the supporting action of the mounting frame (207). Then, when the transmission shafts (210) drive the silica gel layer (208) to rotate through the material feeding wheels (209), the negative film can be horizontally conveyed. S2: The support frame (211) is slidably connected to the guide post (212) through the support spring (213). One end of the guide post (212) penetrates 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) can keep the adjacent two silica gel layers (208) in close contact with the negative film under the elastic support of the support spring (213) through the guide post (212), and keep the stable driving of the negative film by the material feeding wheels (209) through the silica gel layer (208). S3: The material placing box (401) is connected to both the conical input sleeve plate (201) and the conical output sleeve plate (106) through the material guiding grooves (405). The material guiding grooves (405) facilitate the input and output of the negative film inside the material placing box (401). The two elastic pressing pieces (404) facilitate pressing the negative film to keep the negative film in close contact with the upper end surface of the transparent carrier (402). Then, the edge of the negative film is preliminarily scanned by the scanning camera (306) to ensure the accurate positioning of the negative film under the driving action of the material feeding wheel (209) and improve 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 uniformly supplements light to the negative film through the filter lens (108) and the transparent carrier (402). The plurality of scanning cameras (306) can further scan the negative film through the lenses (305) under the supporting action of the mounting sleeves (303) and transmit the image information to the circuit board provided inside the power connection box (301). Then, the circuit board can convert the image information into digital form. S5: By means of the protective box body (102), the material placing box (401) and the light-shielding sleeve (403), it is possible to keep the scanning camera (306) from being affected by external light when scanning the negative film. Rotate the adjustment knob (302) so that the adjustment knob (302) synchronously drives a plurality of lenses (305) to slide vertically at the bottom end of the mounting sleeve (303) through the connecting plate (304), thereby realizing the adjustment of the focal length of the scanning camera (306).
