[0020] Preferably, a method for using a film digitization processing terminal comprises the following steps:
[0021] Step A: When the films to be digitized are of various sizes, the films of various sizes are placed on the upper end surface of the film placement table from front to back. The first downward pressing plate from front to back is then pulled upward until the lower end surface of the rubber strip fixed to its lower end surface is higher than the upper end surface of the film placed on the upper end surface of the film placement table. When the downward pressing plate is pulled upward, it will squeeze the return spring indirectly connected to it. When the lower end surface of the rubber strip is higher than the upper end surface of the film, it is moved to above the front end of the first film from front to back, and then the downward pressing plate is released. After the pressing and fixing plate is released, the pressing and fixing plate is pulled downward by the reaction force of the compressed return spring. When the rubber strip fixed to the lower end surface of the pressing and fixing plate contacts the upper end surface of the front end surface of the first film from the front to the back, the front end of the film can be fixed. Then, the rear end of the first film from the front to the back is fixed by the same method. When the front end and the rear end of the film are both fixed, the film is fixed.

Then, a plurality of side baffles respectively fixed to the lower end surfaces of the two strip plates are pushed toward the square of the roll of negative film by a synchronous moving mechanism until the two are in contact with each other. By pushing the side baffles respectively fixed to the lower end surfaces of the two strip plates, the roll of negative film can be positioned in the middle of the upper end surface of the first sponge cleaning sleeve and kept parallel to the first sponge cleaning sleeve.
[0023] Step C: After the roll film positioning operation is completed, the downward pressure cylinder is started to push the downward pressure roller downward until the lower end surface of the downward pressure roller is in contact with the upper end surface of the roll film, thereby flattening the roll film. Finally, the roll film located between the first sponge cleaning sleeve and the downward pressure roller is driven by the conveyor belt to move. When the pattern on the roll film moves to the bottom of the strip through hole, the pattern on the roll film can be digitized through the scanning chamber.
[0024] Compared with the prior art, the present invention has the following beneficial effects:
[0025] 1. The present invention provides a plurality of downward pressing fixing plates connected to a movable elastic downward pressing mechanism on one side of a film placement table for placing films. When the device needs to be used to scan a large number of films of different sizes, the multiple films are placed on the upper end surface from front to back in sequence. Then, the two downward pressing fixing plates are pulled upward and moved respectively above the front and rear ends of the first film from front to back, and then released to fix the film. Then, all the remaining films are fixed in the same fixing manner. Through the above technical solution, multiple films of different sizes can be fixed to the upper end surface of the film placement table during the same digitization process, thereby improving the processing efficiency of the device for large quantities of films of different sizes.
[0026] 2. When a long roll of negative film needs to be digitized, the present invention places its front end on the upper end surface of the rear end surface of the first sponge cleaning sleeve, and then automatically positions and flattens it through the roll film scanning device, and moves multiple images on the flattened roll film one by one to the lower end surface of the strip through hole, so as to continuously perform digitization processing on this long roll film. The above technical solution improves the processing efficiency of the equipment for long roll films. BRIEF DESCRIPTION OF THE DRAWINGS

The outer surface of the reset rod 14 is sleeved with a reset spring 15, and the upper and lower end surfaces of the reset spring 15 are respectively connected to the inner wall of the cylindrical groove 9 and the upper end surface of the reset metal sleeve 13, and the upper end surface of the reset rod 14 is fixed to the downward pressing fixed plate 10 located above it; since the movable sleeve 8 indirectly connected to the downward pressing fixed plate 10 is movably sleeved on the outer surface of the slide rod 7, the downward pressing fixed plate 10 itself can move parallel to the slide rod 7.
[0039] A rubber strip 12 is fixed to the lower end surface of the pressing and fixing plate 10, and a plurality of protective stripes are provided on the lower end surface of the rubber strip 12;
[0040] The upper end surface of the pressing and fixing plate 10 is fixed with a handle 11; when there are multiple types of films of different sizes to be digitized, the films of different sizes are placed on the upper end surface of the film placement table 5 in sequence from front to back, and then the first pressing and fixing plate 10 from front to back is pulled upward until the lower end surface of the rubber strip 12 fixed to its lower end surface is higher than the upper end surface of the film placed on the upper end surface of the film placement table 5. When the pressing and fixing plate 10 is pulled upward, the reset metal sleeve 13 connected to it by the reset rod 14 will move upward together and squeeze the reset spring 15. When the lower end surface of the rubber strip 12 is higher than the upper end surface of the film, it is moved to above the front end of the first film from front to back, and then the pressing and fixing plate 10 is released. After the pressing and fixing plate 10 is released, the reset metal sleeve 13 The reaction force of the squeezed return spring 15 can pull the pressing fixing plate 10 downward. When the rubber strip 12 fixed to the lower end surface of the pressing fixing plate 10 contacts the upper end surface of the front end surface of the first negative film from the front to the back, the front end of the negative film can be fixed. Then, the rear end of the first negative film from the front to the back can be fixed by the same method. When the front end and the rear end of the negative film are fixed, the negative film is fixed. Finally, the same fixing method can be used to fix multiple negative films of different sizes placed on the upper end surface of the negative film placement table 5. Through the above technical solution, multiple negative films of different sizes can be fixed to the upper end surface of the negative film placement table 5 during the same digitization process, thereby improving the processing efficiency of the equipment for large quantities of negative films of different sizes.
[0041] The handle 11 fixed to the upper end surface of the pressing fixing plate 10 can be used to more conveniently pull the pressing fixing plate 10 upwards to perform the fixing operation;
[0042] When all the films placed on the upper end surface of the film placement table 5 are fixed, the slide 4 with a multi-size film fixing mechanism fixed inside is pushed into the interior of the scanning cavity 3 through the slot 17, and then the film scanner body 1 is started to perform digital scanning and processing on the fixed films, and the converted digital images are transmitted to the cloud, the user's mobile phone or the user's computer.
[0043] A roll film scanning device 2 is provided on one side of the slot 17 and is fixedly mounted on the outer surface of the film scanner body 1. The roll film scanning device 2 includes a conveyor belt 201, a first sponge cleaning sleeve 202, two strip plates 204, multiple side guards 205, multiple pressing cylinders 217, the same number of pressing rollers 218 as the pressing cylinders 217, and a synchronous moving mechanism. The first sponge cleaning sleeve 202 is sleeved on the outer surface of the conveyor belt 201.
[0044] The two strip plates 204 are respectively located on both sides above the first sponge cleaning cover 202, and the multiple side baffles 205 are respectively fixed to the lower end surfaces of the two strip plates 204, and the lower end surfaces of the strip plates 204 are in contact with the upper end surface of the first sponge cleaning cover 202;
[0045] Multiple pressing cylinders 217 are respectively fixed inside the two strip plates 204, and multiple pressing rollers 218 are respectively fixed between the piston rods of the multiple pressing cylinders 217, and the lower end surface of the pressing roller 218 is half a centimeter away from the upper end surface of the first sponge cleaning sleeve 202. The synchronous moving mechanism can synchronously move the two strip plates 204 inward or outward; a control panel 16 is fixedly installed on one side of the outer surface of the film scanner body 1, and the roll film scanning device 2 and the film scanner body 1 are electrically connected to the control panel 16; the roll film scanning device 2 and the film scanner body 1 can be controlled by the control panel 16.
[0046] The synchronous movement mechanism includes a bar-shaped metal shell 203, an adjustment motor 206 is fixedly installed on one side of the inner part of the bar-shaped metal shell 203, the output shaft of the adjustment motor 206 is connected to a transmission shaft 207 through a coupling, a first bevel gear 208 is fixedly sleeved on the outer surface of the transmission shaft 207, and a second bevel gear 209 is meshed on both sides of the outer surface of the first bevel gear 208, and a threaded rod 210 is connected to the axis of the second bevel gear 209, and a concave rod 211 is installed on one side of the outer surface of the threaded rod 210 through a threaded structure; when it is necessary to digitize a long roll of film as a whole, During cleaning operations, the front end portion is placed on the upper end surface of the rear end portion of the first sponge cleaning sleeve 202 fixedly sleeved on the outer surface of the conveyor belt 201, and then the adjustment motor 206 is started. The adjustment motor 206 can drive the transmission shaft 207 connected thereto and the first bevel gear 208 fixedly sleeved on the outer surface of the transmission shaft 207 to rotate. When the first bevel gear 208 rotates, the two second bevel gears 209 meshing therewith will rotate together with it. The rotating second bevel gear 209 can drive the threaded rod 210 connected to the axis of the second bevel gear 209 to rotate synchronously.
[0047] The concave rod 211 is concave in shape as a whole, and the two concave rods 211 are fixed between the two strip plates 204 respectively; since the two concave rods 211 respectively mounted on the two threaded rods 210 by means of a threaded structure are fixed between the two strip plates 204 respectively, the concave rod 211 itself cannot rotate. When the threaded rod 210 rotates, the concave rod 211 which is threadedly connected to it but cannot rotate by itself will move inward or outward under the drive of the threaded structure, and at this time, the two strip plates 204 will be moved inward synchronously. In the process of the strip plates 204 moving inward, the multiple side baffles 205 fixed to the lower end surfaces of the two strip plates 204 will push toward the square of the roll film until the two are in contact with each other. By pushing the side baffles 205, the roll film can be positioned in the middle position of the upper end surface of the first sponge cleaning sleeve 202 and kept parallel to the first sponge cleaning sleeve 202;
[0048] When the roll film positioning operation is completed, the pressing cylinder 217 is started to push the pressing roller 218 downward until the lower end surface of the pressing roller 218 is in contact with the upper end surface of the roll film, thereby flattening the roll film. Finally, the roll film located between the first sponge cleaning sleeve 202 and the pressing roller 218 is driven by the conveyor belt 201 to move. When the pattern on the roll film moves to the bottom of the strip-shaped through hole 216, the pattern on the roll film can be digitized by the scanning chamber 3. The above technical solution can continuously perform digitization operations on longer roll films, thereby improving the processing efficiency of the device for longer roll films.
[0049] When the pressing cylinder 217 is just started to push the pressing roller 218 downward to flatten the roll film, only the pressing cylinder 217 located above the film will be started. The other pressing cylinders 217 will not be started to flatten the roll film until the roll film is conveyed to the bottom thereof by the conveyor belt 201. This operation mode can prevent the front end of the roll film from being blocked by the rear end face of one of the pressing rollers 218 when the roll film is just being conveyed by the conveyor belt 201, thereby causing a large amount of roll film to be blocked at a certain position and be conveyed;
[0050] Finally, the roll film after digital processing will pass through the first sponge cleaning sleeve 202 and be discharged from the rear end surface of the film scanner body 1.
[0051] A strip groove 212 is provided on one side of the lower end surface of each of the two strip plates 204. The interior of the two strip grooves 212 contains a conveyor belt 213 for cleaning the upper end surface of the roll film. The outer surface of the conveyor belt 213 for cleaning the upper end surface of the roll film is fixedly covered with a second sponge cleaning sleeve 214.
[0052] A concave fixing sleeve 215 is fixedly provided on the outer side of the second sponge cleaning sleeve 214. The upper end surface of the concave fixing sleeve 215 is fixedly connected to a plurality of support rods, and the upper end surfaces of the support rods are fixed to the strip-shaped metal shell 203. When the roll film moves on the first sponge cleaning sleeve 202, the first sponge cleaning sleeve 202 can clean its lower end surface.
[0053] As the roll film moves, before being scanned, its upper end surface will contact the second sponge cleaning sleeve 214 fixed to the outer surface of the roll film upper end surface cleaning conveyor belt 213. The second sponge cleaning sleeve 214 can clean the upper end surface of the roll film. With the above technical solution, the upper and lower end surfaces of the roll film can be cleaned before scanning, thereby ensuring the quality of the scanned image.
[0054] The conveyor belt 213 can be fixed at a current position by a concave fixing sleeve 215 located on the outer side of the conveyor belt 213 .
[0055] A plurality of metal rods 219 fixed to the inside of the strip metal shell 203 are provided above the two strip plates 204, and a support sleeve 220 is provided on both sides of the outer surface of the metal rod 219, and the two support sleeves 220 respectively provided on the outer surface of the same metal rod 219 are fixed between the two strip plates 204 respectively; the support sleeve 220 that is fixed on the upper end surface of the strip plate 204 and movably provided on the outer surface of the metal rod 219 can ensure the stability of the moving strip plate 204 and prevent it from tilting, thereby preventing the roll film from being squeezed during the movement.
[0056] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.

The film digitization processing terminal according to claim 5, characterized in that: A plurality of metal rods (219) fixed to the inside of the strip metal shell (203) are provided above the two strip plates (204), and a support sleeve (220) is provided on both sides of the outer surface of the metal rod (219), and the two support sleeves (220) respectively provided on the outer surface of the same metal rod (219) are fixed to the two strip plates (204).
9. The film digitization processing terminal according to claim 1, characterized in that: A control panel (16) is fixedly mounted on one side of the outer surface of the film scanner body (1), and the roll film scanning device (2) and the film scanner body (1) are electrically connected to the control panel (16).
10. A method for using the film digitization processing terminal according to any one of claims 1 to 9, characterized in that: The method of use comprises the following steps: Step A: When the negatives to be digitized are of various sizes, the negatives of various sizes are placed on the upper end surface of the negative placement table (5) from front to back, and then the first downward pressing fixed plate (10) counted from front to back is pulled upward until the lower end surface of the rubber strip (12) fixed to its lower end surface is higher than the upper end surface of the negative placed on the upper end surface of the negative placement table (5). When the downward pressing fixed plate (10) is pulled upward, it will squeeze the return spring (15) indirectly connected to it. When the lower end surface of the rubber strip (12) is higher than the upper end surface of the negative, it is moved to the upper end of the front end of the first negative from front to back, and then the downward pressing fixed plate is released. (10), after the pressing fixing plate (10) is released, the pressing fixing plate (10) can be pulled downward by the reaction force of the compressed return spring (15), and when the rubber strip (12) fixed to the lower end surface of the pressing fixing plate (10) contacts the upper end surface of the front end surface of the first negative film from the front to the back, the front end of the negative film can be fixed, and then the rear end of the first negative film from the front to the back is fixed by the same method. When the front end and the rear end of the negative film are fixed, the negative film is fixed, and finally, the same fixing method is used to fix multiple negative films of different sizes placed on the upper end surface of the negative film placement table (5); Step B: When a long roll of film needs to be digitized, the front end portion thereof is placed on the upper end surface of the rear end portion of the first sponge cleaning sleeve (202) fixedly mounted on the outer surface of the conveyor belt (201), and then a plurality of side baffles (205) respectively fixed on the lower end surfaces of the two strip plates (204) are pushed toward the square of the roll of film through a synchronous moving mechanism until the two are in contact with each other. By pushing the side baffles (205) respectively fixed on the lower end surfaces of the two strip plates (204), the roll of film can be positioned in the middle of the upper end surface of the first sponge cleaning sleeve (202) and kept parallel to the first sponge cleaning sleeve (202); Step C: After the roll film positioning operation is completed, the downward pressure cylinder (217) is started to push the downward pressure roller (218) downward until the lower end surface of the downward pressure roller (218) is in contact with the upper end surface of the roll film, thereby flattening the roll film. Finally, the roll film located between the first sponge cleaning sleeve (202) and the downward pressure roller (218) is driven by the conveyor belt (201) to move. When the pattern on the roll film moves to the bottom of the strip-shaped through hole (216), the pattern on the roll film can be digitized through the scanning chamber (3).
