Description

Technical Field

[0001] The utility model relates to the technical field of photography, in particular to a film developing device. Background Art

[0002] In recent years, film cameras have experienced a resurgence as photography enthusiasts pursue a retro and unique image quality. Film photography offers a unique grain and color reproduction that is difficult to replicate with digital photography. This resurgence has also led to a surge in demand for portable film processors for home use. These portable processors allow photography enthusiasts to develop film at home, eliminating the need for a professional darkroom and bulky automated processing equipment. This provides greater convenience and privacy, while also increasing the enjoyment of photography.

[0003] At present, the shell of a portable developing machine mainly includes a shell and a cover. One side of the shell is open and has independent developing slots, film placement slots and other structures formed inside it. The cover is mainly used to open and close the opening of the shell to cooperate with the shell to form a closed dark space.

[0004] In actual use, when the film is placed in the slot, there is a gap between it and the housing. During film development, the film backing paper needs to be separated. That is, after passing the backing paper through the paper outlet of the film module, it is manually pulled to separate the backing paper from the photosensitive film. However, due to the gap between the housing and the film, the film can easily loosen and move during the pulling process. In severe cases, it can even push the cover out and separate from the housing, causing light leakage and affecting subsequent film development. Utility Model Content

[0035] The present application provides a film developing device for developing a film.

[0036] The following will describe in detail the specific embodiments of the film developing device of the present application with reference to the accompanying drawings.

[0037] Figure 1 is a schematic structural diagram of the film developing device in this embodiment, Figure 2 is Figure 1 a cross-sectional view of the film developing device along the A-A direction in Figure 3 is Figure 2 a schematic enlarged view of the structure at B in Figure 4 is a schematic exploded view of the film developing device in this embodiment.

[0038] Referring to Figures 1 to 4 , the film developing device 100 includes a developing mechanism 1, a light-shielding cover 2, and a crimping member 3. The top of the developing mechanism 1 is open. A film slot 11 communicating with the opening of the developing mechanism 1 is formed on the developing mechanism 1 for accommodating the film to be developed 200. The light-shielding cover 2 is detachably provided at the open end of the developing mechanism 1 for opening and closing the opening of the developing mechanism 1. The crimping member 3 is provided on the light-shielding cover 2, and the arrangement position of the crimping member 3 on the light-shielding cover 2 corresponds to the arrangement position of the film slot 11 on the developing mechanism 1. The crimping member 3 is used for crimping the film to be developed 200 located in the film slot 11.

[0039] In this application, a crimping member 3 is provided on the light-shielding cover 2 corresponding to the film slot 11 on the developing mechanism 1. When the light-shielding cover 2 is placed on the developing mechanism 1, the crimping member 3 can crimp the film to be developed 200 placed in the film slot 11, so as to apply a downward pressure on the film to be developed 200. In this way, the film to be developed 200 can be limited in the up and down direction, so that during the process of separating the backing paper of the film to be developed 200, the film to be developed 200 can only rotate along its own axis, ensuring the smoothness of the backing paper separation, thus facilitating the separation of the backing paper of the film to be developed 200 and effectively ensuring the quality of film development.

[0040] Reference Figure 2 and Figure 4 , the top of the developing mechanism 1 is open. A film slot 11 is formed on the developing mechanism 1. The film slot 11 communicates with the opening of the developing mechanism 1 and is used to accommodate the film to be developed 200.

[0041] A film strip slot 13 is also formed on the developing mechanism 1. The film strip slot 13 is located at the bottom of the film slot 11. The film strip slot 13 has an opening, the bottom of the film slot 11 has an opening, and the opening of the film strip slot 13 communicates with the opening at the bottom of the film slot 11. Among them, the film strip slot 13 is used to receive the film strip after the backing paper of the film to be developed 200 is separated.

[0042] Exemplarily, the developing mechanism 1 includes a housing. Among them, the top of the housing is open, and the inside of the housing is hollow to form a film slot 11 that is the same as the opening of the housing. A film strip slot communicating with the film slot is also formed at the bottom of the film slot inside the housing.

[0043] The developing mechanism 1 is provided with a paper outlet 14. The paper outlet 14 is located at the end of the developing mechanism 1 in the length direction where the film slot 11 is provided. The axial direction of the paper outlet 14 is consistent with the length direction of the developing mechanism 1. In actual application, the backing paper of the film to be developed 200 located in the film slot 11 is separated from the film, and the backing paper is pulled out of the developing mechanism 1 through the paper outlet 14. The end of the film strip extends into the film strip slot 13. Then, by pulling the backing paper, the film to be developed 200 located in the film slot 11 rotates so that the backing paper and the film strip are gradually separated. During this process, the film strip will be wound up in the film strip slot 13.

[0044] Among them, taking Figure 2 the direction shown as an example, the film slot 11 is located on the left side of the paper outlet 14. The backing paper of the film to be developed 200 will pass through the paper outlet 14 from left to right. When pulling the backing paper, the film to be developed 200 rotates in the clockwise direction to ensure the smoothness of the backing paper outlet.

[0045] A rinsing tank 12 is also formed on the rinsing mechanism 1. The rinsing tank 12 communicates with the opening of the rinsing mechanism 1. The rinsing tank 12 is adjacent to the film tank 11 and is used to hold the rinsing liquid. Among them, the rinsing tank 12 and the film tank 11 are independent of each other to prevent the rinsing liquid in the rinsing tank 12 from overflowing into the film tank 11 and affecting the imaging of the film. Specifically, the rinsing tank 12 is formed on one side of the film tank 11 inside the housing along the length direction of the housing.

[0046] The rinsing mechanism 1 includes a spool core rotatably disposed inside the rinsing tank 12 for winding the film. In the actual application process, one end of the film 200 to be rinsed placed in the film tank 11 is connected and fixed to the spool core. As the spool core rotates, the spool core will drag and wind the film. During the process of the spool core winding the film, the film wound on the outer layer of the spool core can come into contact with the liquid medicine in the rinsing tank, thereby realizing the rinsing of the film.

[0047] Figure 5 It is a schematic structural diagram of the light-shielding cover 2 in this embodiment.

[0048] Reference Figure 1 、 Figure 2 、 Figure 4 and Figure 5 The light-shielding cover 2 is detachably disposed at the opening end of the rinsing mechanism 1 for opening and closing the opening of the rinsing mechanism 1. Among them, when the light-shielding cover 2 is connected to the opening end of the rinsing mechanism 1, the light-shielding cover 2 cooperates with the housing to isolate and block external light, thereby ensuring that the brightness of the accommodation space meets the environmental conditions required for film rinsing.

[0049] In this embodiment, the light-shielding cover 2 is snap-connected to the rinsing mechanism 1. Exemplarily, a card slot 15 is provided on the end face of the rinsing mechanism 1. The card slot 15 is located on the periphery of the film tank 11. The edge of the light-shielding cover 2 is placed in the card slot 15 so that the edge of the light-shielding cover 2 fits against the side wall of the card slot 15 to prevent external light from penetrating into the accommodation space through the gap between the light-shielding cover 2 and the side wall of the card slot 15, thereby enhancing the light-shielding ability of the film rinsing device 100. Specifically, the light-shielding cover 2 has a shell-like structure with an open bottom, and its open end cooperates with the card slot 15 so that the light-shielding cover 2 can cover the rinsing mechanism 1.

[0050] Reference Figure 2 、 Figure 3 and Figure 5, the crimping member 3 is provided on the light-shielding cover 2. The arrangement position of the crimping member 3 on the light-shielding cover 2 corresponds to the arrangement position of the film slot 11 on the developing mechanism 1. The crimping member 3 is used to crimp the film to be developed 200 located in the film slot 11, so as to apply a downward pressure to the film to be developed 200. In this way, the film to be developed 200 can be limited in the up-down direction, so that during the process of separating the film backing paper, the film can only rotate along its own axis, so as to ensure the smoothness of the backing paper separation, so as to facilitate the separation of the backing paper of the film. Specifically, the crimping member 3 is connected to the bottom surface of the light-shielding cover 2 and is located inside the light-shielding cover 2.

[0051] In this embodiment, the crimping member 3 is movably connected to the light-shielding cover 2. The crimping member 3 can rotate relative to the light-shielding cover 2 or move along the thickness direction of the light-shielding cover 2, so that one end of the crimping member 3 away from the light-shielding cover 2 can approach or move away from the light-shielding cover 2, so as to adaptively abut against the film to be developed 200 with different thicknesses located in the film slot 11, so as to ensure that during the process of separating the backing paper of the film to be developed 200, the crimping member 3 can always keep abutting against the surface of the film to be developed 200, so as to improve the limiting effect on the film to be developed 200 in the thickness direction of the light-shielding cover 2.

[0052] Among them, the film to be developed 200 initially placed in the film slot 11 has the maximum thickness. At this time, there is the minimum distance between the film to be developed 200 and the bottom surface of the light-shielding cover 2, so that the crimping member 3 arranged between the bottom surface of the light-shielding cover 2 and the top of the film to be developed 200 has the minimum size in the thickness direction of the light-shielding cover 2. As the backing glue of the film to be developed 200 is separated, the thickness of the film to be developed 200 will gradually decrease. During this process, the distance between the film to be developed 200 and the bottom surface of the light-shielding cover 2 gradually increases, and one end of the crimping member 3 arranged between the bottom surface of the light-shielding cover 2 and the top of the film to be developed 200 will gradually move away from the light-shielding cover 2, so that the size of the crimping member 3 in the thickness direction of the light-shielding cover 2 gradually increases, so as to adaptively abut against the film to be developed 200 with different thicknesses located in the film slot 11.

[0053] It should be particularly noted that the crimping member 3 is movably connected to the light-shielding cover 2. Among them, the movable connection here includes direct movable connection and indirect movable connection.

[0054] In this embodiment, the crimping member 3 is indirectly movably connected to the light-shielding cover 2, that is, the crimping member 3 can move along the thickness direction of the light-shielding cover 2 through its own structure so that one end of it away from the light-shielding cover 2 can move.

[0055] In this embodiment, the crimping member 3 includes a connecting portion 31 and a crimping portion 32 that are connected to each other. One end of the connecting portion 31 is connected to the light-shielding cover 2, and the other end of the connecting portion 31 is connected to the crimping portion 32. The crimping portion 32 can move toward the light-shielding cover 2, so that the opposite ends of the connecting portion 31 can approach each other, and the connecting portion 31 is in a compressed state. Alternatively, the crimping portion 32 can move away from the light-shielding cover 2 so that the opposite ends of the connecting portion 31 move relatively away from each other, and the connecting portion 31 expands.

[0056] In the actual application process, the unprocessed film 200 initially placed in the film slot 11 has the maximum thickness. At this time, there is the minimum distance between the unprocessed film 200 and the bottom surface of the light-shielding cover 2. The crimping member 3 abutting between the bottom surface of the light-shielding cover 2 and the top of the unprocessed film 200 has the minimum dimension in the thickness direction of the light-shielding cover 2. At this time, the connecting portion 31 is in a compressed state and can store elastic potential energy. As the backing paper of the unprocessed film 200 is drawn out, the thickness of the unprocessed film 200 located in the film slot 11 will gradually decrease. During this process, the connecting portion 31 is in the process of restoring its natural telescopic state, and releases the elastic potential energy to gradually expand, driving the crimping portion 32 to move so that the end of the crimping portion 32 away from the light-shielding cover 2 moves away from the light-shielding cover 2 to maintain the crimping of the unprocessed film 200.

[0057] Specifically, the connecting portion 31 is arc-shaped. The crimping portion 32 is inclined in the direction from the top surface of the light-shielding cover 2 toward the bottom surface of the light-shielding cover 2. In actual application, for example, as the thickness of the unprocessed film 200 gradually decreases, the connecting portion 31 will gradually expand and release the elastic potential energy. During this process, the crimping portion 32 will rotate downward relative to the light-shielding cover 2 so that its end away from the light-shielding cover 2 gradually moves away from the light-shielding cover 2.

[0058] The inclination direction of the crimping portion 32 is consistent with the concave surface orientation of the connecting portion 31, so as to facilitate the force conversion between the connecting portion 31 and the crimping portion 32, improve the cooperation effect of the connecting portion 31 and the crimping portion 32, and enable the crimping member 3 to better adapt to the thickness change of the unprocessed film 200 located in the film slot 11 during the separation of the backing paper of the unprocessed film 200, and maintain the crimping limit of the unprocessed film 200 with different thicknesses.

[0059] Exemplarily, the crimping portion 32 is inclined from the top surface of the light-shielding cover 2 toward the bottom surface of the light-shielding cover 2 in the direction of the developing tank 12. That is, the crimping portion 32 is inclined from the top surface of the light-shielding cover 2 toward the bottom surface of the light-shielding cover 2 in the direction of the paper outlet 14. This setting makes the inclination direction of the crimping portion 32 consistent with the paper outlet direction of the backing paper of the unprocessed film 200, so that while the crimping portion 32 realizes the crimping of the unprocessed film 200, it can ensure the smoothness of the separation of the backing paper and the film.

[0060] The crimping member 3 may further include a mounting portion 33. The mounting portion 33 and the crimping portion 32 are respectively located at opposite ends of the connecting portion 31, and the mounting portion 33 is used to connect with the light-shielding cover 2. Among them, the mounting portion 33 may be directly fixedly connected to the light-shielding cover 3. Or, the mounting portion 33 is detachably connected to the light-shielding cover 2. For example, the mounting portion 22 may be snap-connected to the light-shielding cover 2. At this time, the film developing device 100 further includes a connecting member 4, and the mounting portion 33 is connected to the light-shielding cover 2 through the connecting member 4. The connecting member 4 is fixed to the light-shielding cover 2. The connecting member 4 is provided with a connecting groove with an opening on one side. One end of the crimping member 3 extends into the connecting groove and is snap-connected to the connecting member 4. Exemplarily, the connecting member 4 opens on one side facing the developing tank 12 along the length direction of the light-shielding cover 2. One end of the mounting portion 33 away from the connecting portion 31 extends into the connecting groove and is snap-connected to the connecting member 4, and the mounting portion 33 is parallel to the bottom surface of the light-shielding cover 2.

[0061] An included angle is formed between the mounting portion 33 and the crimping portion 32. Specifically, the included angle formed between the mounting portion 33 and the crimping portion 32 is less than 90°. Since the mounting portion 33 is parallel to the bottom surface of the light-shielding cover 2, it is convenient to realize the inclined arrangement of the crimping portion 32.

[0062] The crimping member 3 may further include a bending portion 34. The bending portion 34 is connected to the end of the crimping portion 32 away from the connecting portion 31. An included angle is formed between the bending portion 34 and the crimping portion 32, which is used to improve the strength of the end of the crimping portion 32 away from the light-shielding cover 2. The bending portion 34 is located on the side of the crimping portion 32 facing the light-shielding cover 2 to avoid damaging the film 200 to be developed and preventing the rotation of the film 200 to be developed, so as to ensure the smoothness of the separation of the backing paper.

[0063] In this embodiment, the mounting portion 33, the connecting portion 31, the crimping portion 32 and the bending portion 34 are of an integral structure, so that the crimping member 3 has high strength.

[0064] In other embodiments, the crimping member 3 may be composed of a mounting portion 33, a crimping portion 32 and an elastic portion. Exemplarily, the mounting portion 33 is fixed to the bottom surface of the light-shielding cover 2, and the mounting portion 33 extends along the thickness direction of the light-shielding cover 2. The bottom of the mounting portion 33 is open and hollow to form a sliding groove. The crimping portion 32 is limited in the sliding groove of the mounting portion 33 and is in sliding fit with the sliding groove. The crimping portion 32 can slide along the sliding groove to make the end away from the light-shielding cover 2 approach or move away from the light-shielding cover 2. The elastic portion is limited in the sliding groove. One axial end of the elastic portion abuts against the mounting portion 33, and the other end abuts against the crimping portion 32. When the crimping portion 32 slides along the sliding groove towards the direction close to the light-shielding cover 2, the two axial ends of the elastic portion approach each other relatively and deform and are in a compressed state. During this process, the elastic portion accumulates elastic potential energy; when the crimping portion 32 slides along the sliding groove towards the direction away from the light-shielding cover 2, the elastic portion restores deformation and releases elastic potential energy, which is convenient to improve the sliding stability of the crimping portion 32. Among them, the elastic portion described here may be a spring.

[0065] In some embodiments, the crimping member 3 can also be directly movably connected to the light shielding cover 2, that is, the crimping member 3 can be movably connected to the light shielding cover 2 with the help of other components, so that the end away from the light shielding cover 2 can move along the thickness direction of the light shielding cover 2.

[0066] For example, in some embodiments, a rotating shaft can be directly provided through the crimping member 3 and the light shielding cover 2, and the crimping member 32 can be rotatably connected to the light shielding cover 2 via the rotating shaft. In this embodiment, the crimping member 3 can include only the crimping portion 32, omitting the connection portion 31, the mounting portion 33, and the bending portion 34 to simplify the structure of the crimping member 3. Alternatively, the crimping member can be composed of the crimping portion 32 and at least one of the connection portion 31, the mounting portion 33, and the bending portion 34.

[0067] In other embodiments, the crimping member 3 can be directly inserted into the light shielding cover 2 along its thickness, with the crimping member 3 being slidably connected to the light shielding cover 2. In this case, an elastic structure can be provided between the crimping member 3 and the light shielding cover 2. The deformation of the elastic structure enables the crimping member 3 to move stably relative to the light shielding cover 2, thereby better adaptively contacting and positioning the film 200 to be processed. The arrangement of the elastic structure can be referred to in the arrangement of the elastic portion in other embodiments above.

[0068] refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 In this embodiment, a locking member 5 is provided on the light shielding cover 2 and is movably connected to the light shielding cover 2. A locking slot is provided on the processing mechanism 1, into which the locking member 5 can extend to lock the light shielding cover 2 and the processing mechanism 1, thereby strengthening the connection between the light shielding cover 2 and the processing mechanism 1. This prevents the light shielding cover 2 from falling off the processing mechanism 1 during film processing, thereby causing light leakage in the storage space and affecting subsequent film development. Alternatively, the locking member 5 can be withdrawn from the locking slot to unlock the light shielding cover 2 and the processing mechanism 1, thereby facilitating removal of the light shielding cover 2 from the processing mechanism 1.

[0069] Exemplarily, the locking member is provided at one end of the light-shielding cover 2 in the length direction. The locking member 5 includes a sliding portion 51, a locking portion 52, and an elastic portion. Among them, the sliding portion 51 penetrates through the light-shielding cover 2 and the locking portion 52 in the thickness direction of the light-shielding cover 2. The sliding portion 51 is slidably connected to the light-shielding cover 2, and the sliding portion 51 can slide along the length direction of the light-shielding cover 2. The sliding portion 51 is fixedly connected to the locking portion 52. The locking portion 52 is located on the bottom surface of the light-shielding cover 2, and the locking portion 52 can move with the sliding portion 51 to extend into or withdraw from the locking groove. One end of the elastic portion is connected to the bottom surface of the light-shielding cover 2 through a mounting plate. Specifically, the mounting plate is perpendicular to the bottom surface of the light-shielding cover 2 and is fixedly connected to the bottom surface of the light-shielding cover 2. The mounting plate extends along the width direction of the light-shielding cover 2. The axial end of the elastic portion is fixed to the side of the mounting plate close to the sliding portion 51, and the axial other end of the elastic portion is fixed to the sliding portion 51. The locking groove is located on the side wall of the card slot 15, and its opening direction is consistent with the length direction of the flushing mechanism 1. In actual application, an external force is applied to the sliding portion 51 to make the sliding portion 51 move relative to the light-shielding cover 2, and drive the locking portion 52 to move in the same direction, so that the locking member 5 is in an unlocked state, so as to place the light-shielding cover 2 in the card slot 15 of the flushing mechanism 1. During this process, the elastic portion is stretched as the sliding portion 51 moves, and elastic potential energy is accumulated. After the light-shielding cover 2 is placed in the card slot 15 of the flushing mechanism 1, the external force applied to the sliding portion 51 is released. At this time, the elastic portion releases elastic potential energy due to restoring its natural stretching state, so as to drive the sliding portion 51 and the locking portion 52 to reset, and make the locking portion 52 extend into the locking groove, so that the locking member 5 is in a locked state, so as to realize the locking of the light-shielding cover 2 and the flushing mechanism 1.

[0070] In some other embodiments, the opening of the locking groove can face the top of the flushing mechanism 1. The locking member 5 can also be composed of a movable portion, an elastic portion, and a limiting portion. At this time, the movable portion penetrates through the light-shielding cover 2 in the thickness direction of the light-shielding cover 2. The elastic portion is sleeved on the outer periphery of the movable portion. The limiting portion is connected to one end of the movable portion facing the bottom surface of the light-shielding cover 2. The edge of the limiting portion extends outwards beyond the movable portion, and the outer diameter of the limiting portion is larger than the inner diameter of the elastic portion, so as to limit the elastic portion on the movable portion. Among them, when the elastic portion is in a natural stretching state, one axial end of the elastic portion abuts against the bottom surface of the light-shielding cover 2, and the other end abuts against the top surface of the limiting portion. In actual application, an external force is applied to the movable portion to pull the movable portion to move towards the top surface of the light-shielding cover 2. During this process, the elastic portion is compressed and elastic potential energy is accumulated. At this time, the locking member 5 is in an unlocked state. Then the external force applied to the movable portion is released, and the elastic portion will release elastic potential energy due to restoring its natural stretching state, so as to drive the movable portion to move towards the bottom surface of the light-shielding cover 2. At this time, the locking member 5 is in a locked state. Among them, the elastic portion can be a spring.

[0071] In this embodiment, the film developing mechanism 1 further includes an elastic member 6. The elastic member 6 is disposed on the light-shielding cover 2 and is used to abut against the open end of the developing mechanism 1. Among them, when the light-shielding cover 2 is separated from the developing mechanism 1, the elastic member 6 is in a natural expansion and contraction state. When the light-shielding cover 2 is placed in the card slot 15 on the developing mechanism 1, there is a minimum gap between the bottom surface of the light-shielding cover 2 and the top surface of the developing mechanism 1. After the light-shielding cover 2 is locked with the developing mechanism 1 through the locking member 5, the light-shielding cover 2 will exert a downward pressure on the elastic member 6, and the developing mechanism 1 will exert an upward force on the elastic member 6. That is, the light-shielding cover 2 and the developing mechanism 1 squeeze the elastic member 6, causing the relative ends of the elastic member 6 to approach each other and deform into a compressed state, so that the elastic member 6 accumulates elastic potential energy. After unlocking the light-shielding cover 2 and the developing mechanism 1 through the locking member 5, the pressure received by the light-shielding cover 2 is removed, and the elastic member 6 returns to its natural expansion and contraction state and releases the elastic potential energy, and the light-shielding cover 2 is pushed upward, so that the light-shielding cover 2 is separated from the developing mechanism 1, facilitating the user to remove the light-shielding cover 2 from the developing mechanism 1.

[0072] In this embodiment, the elastic member 6 can be a spring piece. At this time, the elastic member 6 is inclined from the top surface of the light-shielding cover 2 towards the bottom surface of the light-shielding cover 2 to facilitate its compression under force.

[0073] In other embodiments, the elastic member 6 can also be a spring. At this time, the axial direction of the elastic member 6 extends along the thickness direction of the light-shielding cover 2 to facilitate its compression under force.

[0074] From the above technical solutions, it can be seen that the present utility model has at least the following advantages and positive effects:

[0075] In this application, by providing a pressing member corresponding to the film slot on the developing mechanism on the light-shielding cover, when the light-shielding cover is covered on the developing mechanism, the pressing member can press the film placed in the film slot to exert a downward pressure on the film, so as to limit the film in the up and down directions, so that during the process of separating the backing paper of the film, the film can only rotate along its own axial direction to ensure the smoothness of the backing paper separation, thus facilitating the separation of the backing paper of the film and effectively ensuring the film developing quality.

[0076] Although the present utility model has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present utility model can be embodied in many forms without departing from the spirit or essence of the utility model, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be broadly construed within the spirit and scope defined by the appended claims. Therefore, all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
