Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0042] The present application provides a film developing device for developing films.

[0043] The specific embodiment of the film developing device of the present application is described in detail below with reference to the accompanying drawings.

[0044] Figure 1 Schematic diagram of the structure of the film developing device in this embodiment. Figure 2 yes Figure 1 Schematic diagram of the AA direction, Figure 3 Schematic diagram of the exploded structure of the film developing device in this embodiment.

[0045] refer to Figure 1 to Figure 3 The film developing device comprises at least two developing tanks 1, at least two film cores 2, and at least one cascade 3. Each developing tank 1 contains a liquid for developing film. A film core 2 is arranged in each developing tank 1, and the film core 2 is rotatably connected to the corresponding developing tank 1, and the film core 2 is used to wind the film. At least two developing tanks 1 are arranged in sequence, and the rotation axes of the film cores 2 in each developing tank 1 are coaxially arranged. At least one cascade 3 is provided between two adjacent developing tanks 1, and the ends of the cascade 3 are connected to the film cores 2 in the corresponding developing tank 1, so that multiple film cores 2 are linked through the cascade 3. One of the cores 2 rotates relative to the developing tank 1, which can drive the cascade 3 and the remaining film cores 2 to rotate, thereby realizing the synchronous rotation of all the film cores 2.

[0046] When a user uses the above-mentioned film developing device to develop films, the user can connect a film to be developed to each core 2, and then connect two adjacent developing tanks 1 through a cascade 3, and connect the ends of the cascade 3 to the cores 2 in the corresponding developing tanks 1, so that when one of the cores 2 is rotated relative to the developing tank 1, the cascade 3 and the remaining cores 2 can be driven to rotate. During this process, each core 2 can simultaneously drag and wrap the film, and drive the film to roll in the chemical solution in the corresponding developing tank 1 and contact with the chemical solution, thereby achieving simultaneous developing of at least two rolls of film, thereby improving the film developing efficiency, so as to meet the film developing needs of users with a large number of films to be developed, and enhancing the user experience.

[0047] In addition, when the user only needs to develop one roll of film, the developing operation can also be performed using a single developing tank 1 and a film core 2.

[0048] refer to Figure 2 and Figure 3 The film developing device includes a shell 4, and the shell 4 includes a shell body 41 and a cover body 42.

[0049] One side of the housing 41 is open. The interior of the housing 41 has an accommodation space for accommodating the flushing tank 1. Exemplarily, the top of the housing 41 is open.

[0050] The cover 42 is detachably connected to the shell 41 and is used to open and close the opening of the shell 41. When the cover 42 is connected to the shell 41 and closed at the opening of the shell 41, the cover 42 can shield external light and prevent external light from entering the accommodating space of the shell 41 through the opening, so as to ensure that the brightness of the accommodating space meets the environmental conditions required for film development. When the cover 42 is removed from the shell 41, the opening of the shell 41 allows the accommodating space to communicate with the outside, and the user can use the opening of the shell 41 as a medium for the accommodating space of the shell 41 to interact with the outside. For example, the user can put a film into or take it out of the accommodating space of the shell 41 through the opening of the shell 41.

[0051] The cover 42 is sealedly connected to the shell 41, so that when the cover 42 is closed at the opening of the shell 41, it can prevent external light from entering the interior of the shell 41 through the gap between the cover 42 and the shell 41 and affecting the brightness of the accommodating space, thereby enhancing the light-proof ability of the outer shell 4 and ensuring that the brightness of the accommodating space meets the environmental conditions required for film developing.

[0052] Exemplarily, a limiting groove is provided on the shell 41, and a limiting platform matching the limiting groove is convexly provided on the cover body 42. When the cover body 42 is covered on the shell 41, the limiting platform engages with the limiting groove to achieve a sealed connection between the shell 41 and the cover body 42.

[0053] In other embodiments, a sealing ring may be provided between the connection between the shell 41 and the cover 42 to seal the gap between the shell 41 and the cover 42 , so as to achieve a sealed connection between the shell 41 and the cover 42 .

[0054] In this embodiment, the number of the housings 4 may be at least two.

[0055] In other embodiments, the number of the housing 4 may also be one.

[0056] In this embodiment, the developing tank 1 is arranged inside the housing 4. The interior of the developing tank 1 is hollow and has an opening at the top, so as to be convenient for containing the chemical solution for developing the film. The opening of the developing tank 1 is communicated with the opening of the housing 41 and the accommodating space. In actual use, the film contacts the chemical solution inside the developing tank 1 to achieve the developing of the film. In addition, the design of the opening at the top of the housing 41 is convenient for the user to directly take out the developed film from the developing tank 1 through the opening of the housing 41 and the opening of the developing tank 1.

[0057] In this embodiment, the washing tank 1 and the shell 4 are arranged in a one-to-one correspondence, that is, each shell 4 is provided with a washing tank 1, so that each washing tank 1 and the corresponding shell 4 can form an independent whole. When the user only needs to develop a roll of film, it is convenient for the user to use the independent whole alone to perform the film developing operation.

[0058] In other embodiments, at least two flushing tanks 1 may be disposed in one housing 4, that is, at least two flushing tanks 1 are integrated inside one housing 4 to facilitate overall carrying and storage.

[0059] In this embodiment, the developing tank 1 and the housing 4 may be an integrated structure. When the film is being developed, the developing tank 1 and the housing 4 remain stationary and do not rotate.

[0060] In other embodiments, the washing tank 1 and the housing 4 can be detachably connected. When the washing tank 1 is connected to the housing 4, the washing tank 1 and the housing 4 remain stationary, and when the film is being washed, the washing tank 1 and the housing 4 do not rotate. In addition, the washing tank 1 can also be removed from the housing 4 to facilitate cleaning alone.

[0061] In this embodiment, there is a gap between the bottom of the flushing tank 1 and the bottom of the housing 4 , so that the flushing tank 1 can be completely accommodated in the housing 4 to protect the flushing tank 1 .

[0062] In this embodiment, the bottom of the flushing tank 1 is arc-shaped to facilitate the collection of the liquid medicine. In other embodiments, the bottom of the flushing tank 1 can also be flat.

[0063] In this embodiment, a core 2 is provided in each washing tank 1, and the core 2 is rotatably connected to the corresponding washing tank 1, and the core 2 is used to wind the film. The bottom arc surface of the washing tank 1 is adapted to the outer periphery of the core 2, so as to gather the liquid medicine, so as to facilitate the core 2 to drive the film to immerse in the liquid medicine. In addition, when the core 2 is installed on the washing tank 1, there is a gap between the core 2 and the inner peripheral wall of the washing tank 1, so as to facilitate the smooth rotation of the core 2.

[0064] Specifically, the core 2 includes a first core 21 and a second core 22 arranged at intervals, and the first core 21 and the second core 22 are arranged corresponding to the opposite side walls of the flushing tank 1, and the first core 21 and the second core 22 are rotatably connected to the corresponding side walls of the flushing tank 1, and the first core 21 and the second core 22 rotate synchronously relative to the flushing tank 1. The first core 21 is provided with a plurality of first annular grooves, and the side wall of each first annular groove has a notch, which is used to achieve communication between two adjacent first annular grooves. The second core 22 is correspondingly provided with a plurality of second annular grooves, and the side wall of each second annular groove has a notch, which is used to achieve communication between two adjacent second annular grooves.

[0065] In actual application, the two sides of one end of the film to be washed are first clamped in the first annular groove located in the middle of the first core 21 and the second annular groove located in the middle of the second core 22. As the first core 21 and the second core 22 rotate synchronously relative to the washing tank 1, the first core 21 and the second core 22 will drag the film, and make the film be wound outward along the middle of the first core 21 and the second core 22 in sequence and clamped in each first annular groove and the corresponding second annular groove. In this process, the film enters the first annular groove located in the outer layer through the notch of the first annular groove, and at the same time, the film enters the second annular groove located in the outer layer through the notch on the side wall of the second annular groove. In this way, the side walls of each first annular groove and the second annular groove can separate the washed and wound parts of the film on the core 2 to prevent the stacked films from contacting each other and causing the films to stick together, and even affecting the clarity of the pictures carried on the films, thereby improving the film imaging yield.

[0066] In this embodiment, the structures of the cores 2 may be the same or different. For example, the spacing, shape and size between the first core 21 and the second core 22 of each core 2 may be the same, so that the same type of film can be processed at the same time. The spacing, shape and size between the first core 21 and the second core 22 of each core 2 may also be different, so that different types of films can be processed at the same time, with high adaptability and strong versatility.

[0067] The core 2 also includes a connecting shaft 23, which passes through the first core 21 and the second core 22. The end of the connecting shaft 23 is rotatably connected to the flushing tank 1 to achieve coaxial connection between the first core 21 and the second core 22, and enable the first core 21 and the second core 22 to rotate synchronously relative to the flushing tank 1.

[0068] In actual application, at least two washing tanks 1 are arranged in sequence, and the rotation axes of the cores 2 in each washing tank 1 are coaxially arranged, so as to realize the coaxial and synchronous rotation of all the cores 2 .

[0069] In this embodiment, a cascade 3 is provided between two adjacent washing tanks 1. The ends of the cascade 3 are connected to the film cores 2 in the corresponding washing tanks 1, so that the multiple film cores 2 are linked through the cascade 3. One of the cores 2 rotates relative to the washing tank 1, which can drive the cascade 3 and the remaining film cores 2 to rotate, and realize the synchronous rotation of all the film cores 2. In this process, each film core 2 can drag and wrap the film at the same time, and drive the film to roll in the liquid medicine in the corresponding washing tank 1 and contact with the liquid medicine, so as to realize the synchronous washing of at least two rolls of film, improve the film washing efficiency, so as to meet the film washing needs of users with a large number of films to be washed, and improve the user experience.

[0070] The cascade member 3 is detachably connected to the washing tank 1, and the cascade member 3 is detachably connected to two adjacent film cores 2. Specifically, the cascade member 3 includes a first rotating part 31 and a second rotating part 32. A perforation is provided on the side wall of each washing tank 1 for the first rotating part 31 or the second rotating part 32 to pass through. The first rotating part 31 passes through the perforation of one of the washing tanks 1 and is detachably connected to the film core 2 located inside the washing tank 1, and the second rotating part 32 passes through the perforation of another washing tank 1 and is detachably connected to the film core 2 located inside the washing tank 1. When installing the film washing device, the two washing tanks 1 and the corresponding film cores 2 can be connected through the cascade member 3, so that at least two film cores 2 can be linked, and the operation is convenient and simple. When the film washing device is not in use, the cascade member 3 can be removed from the two adjacent washing tanks 1 and the corresponding film cores 2 at the same time, so that the disassembly between the two adjacent washing tanks 1 and the corresponding film cores 2 can be realized, so that each washing tank 1 and the film core 2 can be cleaned and stored separately.

[0071] Exemplarily, the cascade member 3 is connected with two adjacent cores 2 by snapping. Specifically, a connecting groove is provided on the connecting shaft 23 of each core 2, and the connecting groove is communicated with the through hole. The first rotating part 31 passes through the through hole of one of the rinsing tanks 1 and can be clamped in the connecting groove communicated with the through hole of the rinsing tank 1; the second rotating part 32 passes through the through hole of the other rinsing tank 1 and can be clamped in the connecting groove communicated with the through hole of the rinsing tank 1. Alternatively, the first rotating part 31 and the second rotating part 32 are provided with connecting grooves, and after the first rotating part 31 or the second rotating part 32 passes through the through hole, the connecting shaft 23 can be clamped in the connecting groove.

[0072] The cascade member 3 is sealed and connected to the washing tank 1. The outer diameters of the first rotating part 31 and the second rotating part 32 are both adapted to the perforations. The cascade member 3 also includes an abutment portion 33, which is connected between the first rotating part 31 and the second rotating part 32. The outer diameter of the abutment portion 33 is larger than the outer diameter of the first rotating part 31 and the outer diameter of the second rotating part 32, and the outer diameter of the abutment portion 33 is larger than the inner diameter of the perforations, so that when the first rotating part 31 and the second rotating part 32 pass through the corresponding perforations respectively, the axial ends of the abutment portion 33 can abut against the side walls of the corresponding washing tank 1, thereby preventing the liquid from splashing during the film washing process and seeping out from the gap between the first rotating part 31 and the perforations or between the second rotating part 32 and the perforations. In addition, it can further prevent light from entering the washing tank 1 to ensure that the brightness in the washing tank 1 meets the environmental conditions for film washing.

[0073] The cascade member 3 is detachably connected to the housing 4. In this embodiment, the cascade member 3 further includes a fixing portion 34, which is arranged around the outer periphery of the abutting portion 33, and the fixing portion 34 is rotatably connected to the abutting portion 33. A through hole 43 is provided on the side wall of each housing 4, and the fixing portion 34 is inserted into the through holes 43 of two adjacent housings 4 and is detachably connected to the two adjacent housings 4. This design enables the cascade member 3 to be connected and fixed to each housing 4, which can improve the stability of the rotation of the first rotating portion 31 and the second rotating portion 32, thereby ensuring the stability of the rotation of all the cores 2.

[0074] Exemplarily, the cascade member 3 is snap-connected with the housing 4. Specifically, a boss 35 is convexly provided on the outer periphery of the fixing portion 34, and a positioning groove 44 is correspondingly provided on the side wall of the housing 4. The positioning groove 44 is located on the peripheral side of the through hole 43 and communicates with the through hole 43. The inner diameter of the through hole 43 is larger than the outer diameter of the abutting portion 33. After the first rotating portion 31, the second rotating portion 32 and the abutting portion 33 all pass through the corresponding through hole 43, the boss 35 on the fixing portion 34 can be snapped into the corresponding positioning groove 44, thereby limiting the fixing portion 34 from rotating relative to the housing 4, and keeping the fixing portion 34 and the housing 4 relatively fixed.

[0075] In other embodiments, a positioning groove 44 may be provided on the fixing portion 34 , and a boss 35 may be provided on the side wall of the housing 4 accordingly.

[0076] In other embodiments, the cascade member 3 may also omit the setting of the fixing portion 34. Specifically, the abutting portion 33 is directly inserted into the through hole 43 of the two adjacent shells 4 and is detachably connected to the two adjacent shells 4. The abutting portion 33 is rotatably connected to the first rotating portion 31 and the second rotating portion 32. In this way, while ensuring the rotation of the first rotating portion 31 and the second rotating portion 32, the structure of the cascade member 3 can be appropriately simplified. At this time, the inner diameter of the through hole 43 is adapted to the outer diameter of the abutting portion 33.

[0077] The cascade member 3 is sealed and connected to the housing 4. Specifically, the cascade member 3 further includes a sealing portion 36, which is arranged around the outer periphery of the fixing portion 34, and the outer diameter of the sealing portion 36 is larger than the outer diameter of the through hole 43, and is used to abut against the housing 4. When the first rotating portion 31 (the second rotating portion 32), the abutting portion 33 and the fixing portion 34 pass through the through hole 43, the axial ends of the sealing portion 36 can abut against the side walls of the two housings 4 respectively, thereby preventing external light from entering the interior of each housing 4 through the gap between the fixing portion 34 and the through hole 43, so as to ensure that the brightness of the accommodating space of each housing 4 meets the environmental conditions for film washing.

[0078] In other embodiments, when the fixing portion 34 is omitted from the cascade member 3, the sealing portion 36 can be arranged around the outer periphery of the abutment portion 33 to prevent external light from entering the interior of each outer shell 4 through the gap between the abutment portion 33 and the through hole 43, so as to ensure that the brightness level in the accommodating space of each outer shell 4 meets the environmental conditions for film developing.

[0079] In other embodiments, when at least two flushing tanks 1 are jointly arranged in a shell 4, the sealing portion 36 and the fixing portion 34 of the cascade member 3 can also be omitted. At this time, the first rotating portion 31, the second rotating portion 32 and the abutting portion 33 are rotatably connected, and the abutting portion 33 is detachably connected to the two adjacent flushing tanks 1.

[0080] In this embodiment, the film developing device further includes a clamping member 5. A clamping slot 51 is formed on the clamping member 5, and the clamping member 5 is arranged through two adjacent shells 4, and the clamping slot 51 is clamped with the side walls of the two adjacent shells 4 with the through holes 43, so as to connect and fix the two adjacent shells 4, so as to ensure that all the shells 4 remain relatively still, and further ensure the stability of the cascade member 3 dragging each chip 2 to rotate.

[0081] Exemplarily, the shell 4 is provided with a plug-in interface, and the side wall provided with the plug-in interface is perpendicular to the side wall provided with the through hole 43. The clamping member 5 includes two clamping parts 52 and a connecting part 53 connected to the ends of the two clamping parts 52. Each clamping part 52 extends into a corresponding plug-in interface, and the clamping part 52 abuts against the side wall provided with the through hole 43 of the corresponding shell 4, and the connecting part 53 abuts against the ends of the side walls provided with the through holes 43 of the two adjacent shells 4, thereby realizing the clamping of the two adjacent shells 4. Specifically, the bottom of the shell 4 is open to form a plug-in interface, and the two clamping parts 52 of the clamping member 5 extend into the corresponding shell 4 from the bottom of the two adjacent shells 4 in a one-to-one correspondence, thereby realizing the clamping of the two adjacent shells 4.

[0082] The side wall of the shell 4 provided with the through hole 43 is provided with a receiving portion 45 with an opening facing the plug-in port, for receiving the connecting portion 53 of the clamping member 5. Specifically, the bottom of the side wall of the shell 4 provided with the through hole 43 forms the receiving portion 45, and when the clamping member 5 is clamped on two adjacent shells 4, the connecting portion 53 is received in the receiving portion 45 of the two adjacent shells 4, and the bottom of the connecting portion 53 is not lower than the lowest point of the side wall of the shell 4 provided with the through hole 43, so that when each shell 4 is placed on the supporting surface, the clamping member 5 will not exceed the lowest point of the shell 4 downward, thereby preventing the bottom plane of the shell 4 from contacting the supporting surface, and affecting the supporting stability of the shell 4. Therefore, this design can improve the supporting stability of each shell 4 while strengthening the connection stability between the two adjacent shells 4, thereby ensuring the stability of the rotation of the chip core 2.

[0083] The film developing device further comprises a knob member 6 .
