Description

Technical Field

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

[0002] With the resurgence of film cameras, the demand for portable home processing machines has also increased. These portable processing machines allow photography enthusiasts to develop film at home without the need for professional darkrooms and bulky automatic processing equipment, providing greater convenience and privacy while also increasing the fun of photography.

[0003] Existing home or small film processors typically include a processing box, a film core, and a guide assembly. The processing box is provided with a processing chamber and a mounting chamber. The film to be processed is installed in the mounting chamber and is wound onto the film core disposed in the processing chamber via the guide assembly. The rotation of the film core then drives the film on the roll to be processed in the processing chamber. After the film is completely pulled out of the mounting chamber, the tail end of the film needs to be cut off to separate it from the film roll. At this time, a small portion of the tail of the film remains outside the film core. In existing designs, after the film is cut, the guide assembly will fall toward the film core due to its own gravity, pressing on the film on the core, causing the core to only rotate forward or reverse. When the user needs to complete the film processing by switching between forward and reverse directions, the guide assembly will block the tail end of the film and cause it to become stuck, seriously affecting the user experience and the processing effect.

[0037] See also Figures 1 to 3 , a camera film 10 developing device includes a developing box 100, a film core 122 and a guide assembly.

[0038] The developing box 100 is internally provided with a mounting cavity 230 for accommodating the film 10 and a rinsing cavity 121 for accommodating the developing solution. Initially, the film 10 is placed in the mounting cavity 230 and subsequently wound onto the film core 122 in the rinsing cavity 121 for developing.

[0039] In some embodiments, the film core 122 is rotatably disposed in the washing chamber 121. When the film 11 on the film roll 10 is completely wound onto the film core 122, the film core 122 rotates in the washing chamber 121, so that the film 11 can be evenly immersed in the washing liquid for washing.

[0040] Furthermore, the guide assembly includes a guide portion 130 and an elastic member 140. The guide portion 130 is disposed in the developing box 100 and has opposing first and second ends. The first end of the guide portion 130 faces the film core 122, and the second end of the guide portion 130 is movably connected to the developing box 100. The films 11 in the film roll 10 are sequentially wound onto the film core 122 via the second and first ends of the guide portion 130, thereby gradually transferring the films 11 on the film roll 10 from the mounting cavity 230 to the developing cavity 121 under the guidance of the guide portion 130. It should be noted that when the films 11 are guided by the guide portion 130, they press against the guide portion 130, exerting a downward force on the guide portion 130.

[0041] In this embodiment, one end of the elastic member 140 is connected to the developing box 100, and the other end of the elastic member 140 is connected to the guide portion 130. After the film 11 is completely transferred from the spool on the film roll 10 to the film core 122, the film 11 at the trailing end of the film roll 10 is cut off, and the film 11 is separated from the guide portion 130. The pressure exerted by the film 11 on the guide portion 130 is released, and the elastic member 140 can exert a force on the guide portion 130 to move away from the film core 122, thereby driving the guide portion 130 away from the film core 122. After the film 11 is completely wound onto the film core 122, the guide portion 130 remains separated from the film 11. At this time, the film core 122 can freely switch between forward and reverse rotation without interference from the guide portion 130, which is beneficial to the rolling of the film 11 and ultimately improves the film 11 processing effect and user experience.

[0042] In some embodiments, the processing box 100 includes a processing box body 120 and a top cover 110. The processing box body 120 defines the processing chamber 121. An opening communicating with the processing chamber 121 is provided at the top of the processing box body 120, allowing processing fluid to be added to the processing chamber 121 and for film 11 to be removed and placed in the processing chamber. The top cover 110 detachably covers the top of the processing box body 120 to open and close the opening.

[0043] The entire flushing box body 120 can be made of an opaque material, and a flushing knob can be provided on the outside of the flushing box body 120 for manually driving the tablet core 122. The upper cover 110 can also be made of an opaque material so that when the upper cover 110 is placed on the top of the flushing box body 120, a dark flushing space can be formed between the two.

[0044] The camera film developing device of the present application can be used for both electric and manual development. Users can choose between electric and manual development based on their actual needs. In particular, when the internal battery of the device is low, the user can manually develop the film 10. Therefore, the camera film developing device of the present application is more convenient to use and can meet the needs of users in various scenarios.

[0045] In some embodiments, the camera film developing device further includes a rotary cutting assembly 200. The rotary cutting assembly 200 includes a housing 210 and a cutter 220. The housing 210 defines the aforementioned mounting cavity 230, and the camera film 10 is initially placed in the mounting cavity 230. The housing 210 has a rim portion on one side of the mounting cavity 230, and the inner sidewall 123 of the rim portion can extend to connect with the mounting cavity 230. The cutter 220 is movably disposed within the housing 210. A side of the rim portion, adjacent to the mounting cavity 230, defines an opening for the cutter 220 to pass through. The cutter 220 can move toward the upper surface of the rim portion to cut the film 11.

[0046] By providing the rotary cutter assembly 200, the camera film developing device is able to shear the trailing end of the film 11 of the film roll 10, separating it from the spool, eliminating the need for manual cutting. Because the film 11 cutting process is performed within the camera film developing device, there is no need to remove the film 10 for shearing, effectively preventing the exposure of portions of the negative film during shearing. When the camera film 10 is fully wound onto the film core 122, guided by the guide 130, the rotary cutter assembly 200 shears the trailing end of the film 11, separating it from the spool. Subsequently, the film core 122 rotates within the developing chamber 121, evenly immersing the film 11 in the developing solution for processing.

[0047] In the present application, the rotary cutting assembly 200 is provided on the developing box body 120, which is used to install the camera film 10 and to cut and separate the tail end of the film 11 from the reel. The rotary cutting assembly 200 can be provided between the upper cover 110 and the developing box body 120 and is located outside the developing space.

[0048] The peeling assembly 200 can be detachably connected to the flushing box body 120. Specifically, the housing 210 of the peeling assembly 200 is detachably connected to the flushing box body 120. After the housing 210 and the flushing box body 120 are connected in place, the upper cover 110 is placed over the housing 210 and the flushing box body 120.

[0049] The flushing box body 120 can be roughly rectangular in shape. The flushing box body 120 is provided with a mounting position for mounting the peeling assembly 200. The mounting position is roughly stepped, for example, it can be a one-step structure (L-shaped). For example, the side of the flushing box body 120 close to the flushing space is provided with a vertically arranged side wall 123 and a bottom wall 124 perpendicularly connected to the bottom of the side wall 123. The bottom wall 124 and the side wall 123 can form a stepped mounting position. The peeling assembly 200 is removably mounted in this mounting position. As an example, the bottom wall 124 is at a certain height from the bottom surface of the flushing box body 120.

[0050] In other embodiments, the peeling assembly 200 may also be fixedly connected to the flushing box body 120, that is, the housing 210 and the flushing box body 120 are an integral structure and the two cannot be separated.

[0051] Continue to see Figures 4 to 7 In some embodiments, the second end of the guide portion 130 is configured to be movably disposed on the developing box 100 in a vertical direction. Specifically, the second end of the guide portion 130 is connected to the developing box body 120. The elastic member 140 is connected to the guide portion 130. When the film 11 is cut from the film roll 10 to release the pressure of the film 11 on the guide portion 130, the elastic member 140 can apply a force to the guide portion 130 to move the guide portion 130 upward and away from the film core 122. Therefore, after the film is completely wound onto the film core, the guide portion 130 and the film are separated and remain separated.

[0052] In some embodiments, the elastic member 140 can be a compression spring, one end of which is connected to the bottom of the guide portion 130 and the other end is connected to the washing box body 120. When the film 11 is pressed against the guide portion 130, the elastic member 140 is compressed and stores force, so that when the film 11 is cut, the elastic member 140 can release the elastic force and push the guide portion 130 away from the film core 122. When the second end of the guide portion 130 can be moved in the vertical direction to be connected to the washing box 100, the elastic member 140 is connected to the bottom of the second end of the guide portion 130, so that the guide portion 130 can be lifted upward to move it away from the film core 122.

[0053] In some embodiments, when two elastic members 140 are provided and connected to the bottom of the first end and the second end of the guide portion 130 respectively, the guide portion 130 can be pushed upward as a whole, so that the guide portion 130 moves in a direction away from the core 122.

[0054] In this embodiment, the elastic member 140 can also be connected to the second end of the guide portion 130 to apply a torsional force to the rotation of the guide portion 130, so that it drives the guide portion 130 to rotate in a direction away from the film core 122, thereby making the first end of the guide portion 130 away from the film core 122 and remain separated from the film on the film core.

[0055] Specifically, the guide portion 130 includes a body 131 and a mounting shaft 135. The body 131 is the main structure of the guide portion 130 and has a first end and a second end. The first end of the body 131 constitutes the first end of the guide portion 130 and faces the tablet core 122, while the second end of the body 131 constitutes the second end of the guide portion 130. The mounting shaft 135 is fixedly connected to the second end of the body 131 and is vertically movable on the flushing box 100. Therefore, upward movement of the mounting shaft 135 can move the body 131 upward and away from the tablet core.

[0056] Furthermore, the elastic member 140 is a torsion spring. The torsion spring is mounted on the mounting shaft 135, and the tail end of the torsion spring is connected to the processing box 100, specifically, to the processing box body 120. When guiding the film 11, the film 11 is sequentially wound from the second end to the first end of the body 131 onto the film core 122. The film 11 presses against the body 131, causing the body 131 to press downward toward the film core 122. At this time, the torsion spring accumulates force. When the film 11 is cut from the film roll and the contact film presses against the body 131, the torsion spring exerts a force on the mounting shaft 135. This force, generated by the elastic deformation of the torsion spring, is applied to the mounting shaft 135, causing the mounting shaft 135 to move the body 131 upward and away from the film core 122, and maintain separation from the film on the film core 122 during the subsequent processing process.

[0057] It can be understood that after the film 11 is cut from the film roll 10, the last section of the film is still attached to the main body 131. At this time, the core 122 can continue to be rotated, so that the film 11 is completely separated from the main body 131. The main body 131 is pulled away from the core 122 due to the drive of the installation shaft 135, and due to the torsion of the torsion spring, the main body 131 remains separated from the film on the core 122.

[0058] In some embodiments, the mounting shaft 135 can be integrally formed with the second end of the body 131, and the two are a whole, with the side portion of the second end of the body 131 protruding from the body 131 to form the mounting shaft 135. The mounting shaft 135 can also be a separate component from the body 131, and the mounting shaft 135 is fixedly mounted on the second end of the body 131.

[0059] In some embodiments, a vertically extending retaining groove 125 is defined within the flushing box body 120. The mounting shaft 135 is disposed at the bottom of the retaining groove 125 and is movable along the retaining groove 125. The walls of the retaining groove 125 limit and guide the mounting shaft 135, ensuring that the mounting shaft 135 can only move vertically within the retaining groove 125. The retaining groove 125 is in communication with the flushing chamber 121, allowing the mounting shaft 135 to extend into the retaining groove 125.

[0060] In some embodiments, a ring portion may be provided on the top end wall of the flushing cavity 121 in the flushing box body 120, and a certain gap may be provided between the outer side of the ring portion and the outer peripheral wall of the flushing box body 120 so that the edge of the upper cover 110 can be inserted into the gap, thereby facilitating the installation of the upper cover 110.

[0061] In this embodiment, the limiting groove 125 is opened on the inner side wall 123 of the ring part, so that the installation shaft 135 can be set on the upper side of the washing chamber 121, and the main body 131 can be set in the upper space of the washing chamber 121. After the main body 131 is driven by the installation shaft 135 to move upward, it can have a larger distance from the film core 122, thereby avoiding interference with the rolling of the film 11, and making the film core 122 drive the film 11 to rotate forward and reverse more smoothly.

[0062] It should be noted that two opposite limit grooves 125 can be provided in the flushing box body 120. The two limit grooves 125 can be symmetrically arranged about the flushing cavity 121. Accordingly, the two ends of the installation shaft 135 are respectively connected to the two limit grooves 125, so that the movement of the main body 131 is more stable.

[0063] In some embodiments, a pressing portion 111 may be further provided at the bottom of the upper cover 110. The pressing portion 111 corresponds to the position of the limiting groove 125 so that when the upper cover 110 is closed on the top of the developing box body 120, it extends into the limiting groove 125 and defines a space for the installation shaft 135 to move together with the groove wall of the limiting groove 125, allowing the installation shaft 135 to move within a certain space. The space for the body 131 to move is controllable, and it is also convenient to install the installation shaft 135 in the limiting groove 125. At the same time, the provision of the pressing portion 111 can limit the height difference between the body 131 and the outermost circle of the film core 122 after the body 131 moves upward, so that the height difference does not affect the correct winding of the last section of the film onto the film core 122.

[0064] In some embodiments, the pressing portion 111 can be adapted to the cross-sectional shape of the limiting groove 125 so as to fit neatly into the limiting groove 125. When the film 11 is cut, the pressing force of the film 111 on the body 131 is released, and the torsion force of the torsion spring causes the mounting shaft 135 to move upward, thereby driving the body 131 upward. However, since the mounting shaft 135 is vertically restricted by the pressing portion 111, it is restricted in movement after driving the body 131 upward for a certain distance. The torsion force of the torsion spring keeps the body 131 separated from the film on the core 122.

[0065] In some embodiments, the retaining groove 125 includes a first groove 126 and a second groove 127, which are arranged sequentially from the second end to the first end of the body 131. The first groove 126 and the second groove 127 are interconnected. The mounting shaft 135 is disposed at the bottom of the first groove 126. The pressing portion 111 corresponds to the first groove 126, so that when the upper cover 110 is closed on the top of the developing box body 120, it extends into the first groove 126 and defines a space for the mounting shaft 135 to move together with the groove wall of the first groove 126. The tail end of the torsion spring abuts the bottom of the second groove 127. When the first end of the body 131 is pressed by the film 11, the torsion spring begins to deform and accumulate force. When the film 11 is cut from the film roll, the torsion force of the torsion spring acts on the mounting shaft 135, causing it to move upward.

[0066] In some embodiments, a first slot body 126 and a second slot body 127 are provided to define the positions of the mounting shaft 135 and the torsion spring, respectively, so that they are disposed in corresponding slot bodies. The slots of the first slot body 126 and the second slot body 127 both face the flushing cavity 121 to communicate with the flushing cavity 121. A stopper 128 may be provided at the connection between the first slot body 126 and the second slot body 127. The stopper 128 is located at the edge of the top end wall of the flushing cavity 121, and a certain gap is formed between the stopper 128 and the sidewalls 123 of the first slot body 126 and the second slot body 127 to form a limiting channel for the tail end of the torsion spring to pass through. The tail end of the torsion spring enters the second slot body 127 through the limiting channel, thereby further defining the position of the torsion spring.

[0067] In some embodiments, the body 131 includes a guide plate 132 and two stop plates 133. The guide plate 132 may be a flat plate, with one end facing the film core 122 and constituting the first end of the body 131. The other end of the guide plate 132 is fixedly connected to a mounting shaft 135, constituting the second end of the body 131. The film 11 passes over the guide plate 132 and is pressed against its surface. The two stop plates 133 are connected to opposite sides of the guide plate 132. The distance between the two stop plates 133 matches the width of the film 11 to be processed. The two stop plates 133 and the guide plate 132 form a guide channel for the film 11 to pass through. The film 11 is wound onto the film core 122 through the guide channel. The two stop plates 133 limit the sides of the film 11, ensuring that the film 11 can only pass along the guide channel onto the film core 122, maintaining alignment between the film 11 and the film core 122.

[0068] In some embodiments, the limiting plate 133 protrudes upward from the guide plate 132, and the top ends of the two limiting plates 133 are bent toward each other to form a bending portion 134. There is a gap between the two bending portions 134 and the surface of the guide plate 132, allowing the film 11 to pass through it, thereby preventing the film 11 from easily falling out of the limiting channel upward.

[0069] In some embodiments, a mounting hole 1323 is formed through the end of the guide plate 132 facing away from the core 122. A mounting shaft 135 is disposed in the mounting hole 1323. The mounting shaft 135 can be fixedly connected to the mounting hole 1323 so that the mounting shaft 135 drives the guide plate 132 to mount the shaft 135. The ends of the mounting shaft 135 extend into the ends of the mounting hole 1323 and each has a mounting area 136 for mounting a torsion spring.

[0070] In some embodiments, the mounting hole 1323 can also be a blind hole. Mounting holes 1323 are provided on opposite sides of the guide plate 132. Two mounting shafts 135 are correspondingly provided and respectively connected to the two mounting holes 1323 to drive the guide plate 132 to move.

[0071] In this embodiment, the mounting areas 136 at both ends of the mounting shaft 135 are respectively installed with the above-mentioned torsion springs, and the tail ends of the two torsion springs are respectively arranged in the corresponding second grooves 127, so that both ends of the mounting shaft 135 can be connected to the torsion springs. After the film is cut, the torsion force applied to the mounting shaft is stronger and more balanced, and the guide plate can be driven away from the film core 122 faster and to a greater extent.

[0072] In some embodiments, the mounting area 136 is a groove provided at the end of the mounting shaft 135 , and the main body of the torsion spring is sleeved in the groove, thereby limiting the torsion spring in the axial direction of the mounting shaft 135 to prevent it from falling off the mounting shaft 135 .

[0073] In some embodiments, to accommodate films 11 of varying widths, the distance between the two limiting plates 133 needs to be adjustable. Therefore, the guide plates 132 include a first guide plate 1321 and a second guide plate 1322. One end of each of the first and second guide plates 1321 and 1322 faces the film core 122. Mounting holes 1323 are defined on the other ends of each of the first and second guide plates 1321 and 1322. The mounting shaft 135 passes through the mounting holes 1323 of each of the first and second guide plates 1321 and 1322, connecting the mounting shaft 135 to both the first and second guide plates 1321 and 1322. By positioning the first and second guide plates 1321 and 1322 at different positions on the mounting shaft 135, the distance between the first and second guide plates 1321 and 1322 can be adjusted.

[0074] Among them, the two limit plates 133 are respectively connected to the opposite sides of the first guide plate 1321 and the second guide plate 1322. The two limit plates 133, the first guide plate 1321 and the second guide plate 1322 are enclosed to form the above-mentioned guide channel, so that by adjusting the relative positions of the first guide plate 1321 and the second guide plate 1322 on the mounting shaft 135, the distance between the two limit plates 133 can be adjusted to adapt to films 11 of different widths.

[0075] In some embodiments, the guide plate 132 may be an integral component, the guide plate 132 itself does not need to be adjusted, and the two limit plates 133 are movably arranged on the guide plate 132. The two limit plates 133 can be moved closer to or away from each other, thereby directly adjusting the distance between the two limit plates 133 to adapt to films 11 of different widths.

[0076] In this embodiment, a mounting post 1325 and a positioning hole are respectively provided on the opposite side of the first guide plate 1321 and the second guide plate 1322, and the positions of the mounting post 1325 and the positioning hole correspond to each other. When the distance between the first guide plate 1321 and the second guide plate 1322 is adjusted to zero and the two are in contact with each other, the mounting post 1325 is snapped into the positioning hole to fix the first guide plate 1321 and the second guide plate 1322 into a whole. At this time, the distance between the two limit plates 133 is the shortest to adapt to the film 11 with the smallest width, such as the film 11 of the 135 model film 10.

[0077] In some embodiments, a mounting portion 1326 may be formed by protruding downward on one side opposite to the first guide plate 1321 and the second guide plate 1322 , and the mounting posts 1325 and the positioning holes are respectively provided on the corresponding mounting portions 1326 .

[0078] In some embodiments, a buckle 1327 and a slot can be respectively provided on the opposite sides of the first guide plate 1321 and the second guide plate 1322. When the first guide plate 1321 and the second guide plate 1322 are in contact with each other, the buckle 1327 is engaged in the slot, thereby fastening the first guide plate 1321 and the second guide plate 1322, and cooperating with the mounting column 1325 to be engaged in the positioning hole, so that the connection between the first guide plate 1321 and the second guide plate 1322 is more stable.

[0079] When it is necessary to adapt to a wider film 11, for example, to adapt to a film 11 of a 120-size film 10, the first guide plate 1321 and the second guide plate 1322 can be moved in opposite directions along the mounting axis 135 until the distance between the two limit plates 133 is adapted to the width of the film 11 of the 120-size film 10. At this time, the mounting column 1325 and the positioning hole are disengaged.

[0080] In some embodiments, the mounting shaft 135 is provided with a guide groove 137 along its axial direction, and the inner wall of the mounting hole 1323 is provided with a guide post 1324 along its axial direction. The guide post 1324 is engaged with the guide groove 137, thereby connecting the first guide plate 1321 and the second guide plate 1322 to the mounting shaft 135. The first guide plate 1321 and the second guide plate 1322 are prevented from rotating relative to the mounting shaft 135, so that movement of the mounting shaft 135 can drive movement of the guide plate 132. The provision of the guide groove 137 and the guide post 1324 allows the first guide plate 1321 and the second guide plate 1322 to slide in and out along the direction of the guide groove 137, facilitating adjustment of the distance between the first guide plate 1321 and the second guide plate 1322. Once adjusted into place, they can be locked using a locking member, or they can be fastened using the dimensional relationship between the guide groove 137 and the guide post 1324.

[0081] In some embodiments, one end of the guide groove 137 passes through the end of the mounting shaft 135, so that when the first guide plate 1321 and the second guide plate 1322 are installed, they can move inward from the end of the mounting shaft 135, thereby facilitating the installation of the first guide plate 1321 and the second guide plate 1322 onto the mounting shaft 135.

[0082] The process of using the camera film 10 developing device of the present application is as follows:

[0083] Typically, the camera film roll 10 has a free end (head end) and a connecting end (tail end), which is secured to the reel. The camera film roll 10 is first installed in the mounting cavity 230 . The free end of the film 11 is then pulled out of the mounting cavity 230 and wound along the guide portion 130 onto the film core 122 . The top cover 110 is then replaced.

[0084] When the film 11 is completely wound onto the core 122, the film 11 is cut by the rotary cutting assembly 200, so that the tail end of the film roll 10 is separated from the reel. At this time, the pressure of the film on the guide part 130 is released, and the force applied by the elastic member 140 to the guide part 130 causes the guide part 130 to move away from the core 122, thereby decoupling the guide part 130 and the core 122. Afterwards, when the core 122 rotates in the washing chamber 121, the film 11 can be evenly immersed in the washing solution to achieve washing.
