Description

Technical Field

[0001] This utility model belongs to the field of photosensitive film processing and developing, specifically relating to a roll-type photosensitive film processing and developing structure and a roll-type photosensitive film processing and developing machine having the same structure. Background Technology

[0002] In existing technology, film processing refers to the process by which the latent image on the film needs to be transformed into a visible image through development and fixing. Film processing is another important step that determines the quality of the photograph. During processing, the processing time, chemical temperature, and chemical concentration all affect the density, contrast, tone, and tonal range of the negative. Therefore, "timed, temperature-controlled, and concentration-controlled" have become the basic requirements for film processing.

[0003] In traditional film developing machines, the concentration and level of the chemicals change as the film reacts with the chemicals, which affects the reaction time and effectiveness between the film and the chemicals, thus compromising the quality of the film developing.

[0004] Therefore, how to provide a new roll-type photosensitive film developing and processing machine that can ensure the stability of the chemical solution level and concentration is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

The film guide is installed at the lifting end of the lifting frame. Two or more chemical tanks are arranged in the inner cavity of the chemical tank along the film's forward direction.

[0008] Each of the aforementioned medicine tanks is internally arranged with a partition that divides it into a main medicine tank and an auxiliary medicine tank. The upper end of the partition is provided with an overflow channel from the main medicine tank to the auxiliary medicine tank. The film guide is arranged corresponding to the main medicine tank. The one-way circulation section connects the bottom of the main medicine tank and the auxiliary medicine tank with the upper port of the main medicine tank and allows one-way flow, with the flow direction being one-way from the bottom of the main medicine tank and the auxiliary medicine tank to the upper opening of the main medicine tank.

[0009] Preferably, the one-way circulation section includes a main drug solution outlet circulation pipe, an auxiliary drug solution outlet circulation pipe, a circulation connecting pipe, a one-way valve, and a circulation pump.

[0010] Preferably, the roll-type photosensitive film developing structure further includes a water heating tank, wherein the liquid tank is located inside the water heating tank and a space is arranged between its outer wall and the inner wall of the water heating tank to accommodate temperature-controlled liquid.

[0011] Preferably, it also includes a water rinsing tank, which is divided into a main tank and an auxiliary tank by a partition. The water capacity of the main tank is smaller than that of the auxiliary tank. There is an overflow gap between the lower end of the partition and the bottom of the water rinsing tank. The main tank is provided with a water inlet, and the auxiliary tank is provided with a water outlet. The water outlet is rotatably connected to a water outlet pipe so that the water level can be controlled by rotating the height of the water outlet pipe. The main tank and the auxiliary tank are connected by the overflow gap.

[0017] Through the above technical solution, this utility model solves the problem of unstable washing quality caused by the unstable liquid level of traditional film developing machines. The unidirectional circulation section, with its interconnected structure and circulation direction, ensures that the liquid level in the main liquid tank is always flush with the upper end of the partition and in an overflow state, thus keeping the liquid level at the same height and making the film washing quality more stable. The film guide section is installed at the lifting end of the lifting frame. The lifting frame lifts the film washing bracket above the liquid tank, allowing the film to be threaded onto the film washing bracket first, and then lowered into the liquid tank or water rinsing tank by the lifting frame, facilitating the arrangement of the film in the lifting frame. The design of multiple liquid tanks and water rinsing tanks allows the film to be soaked in different liquids in sequence to complete the film washing, and then the residual liquid on its surface is rinsed in the water rinsing tank. It has a high degree of integration, high efficiency, and stable structure.

[0018] This utility model also provides a roll-type photosensitive film developing and processing machine, comprising:

[0030] Preferably, in the film blowing structure, the air outlets of the two nozzles correspond to the two side surfaces of the image surface of the film; the length direction of the air outlet of the nozzle is arranged at an angle to the direction of film movement; the blowing direction of the air outlet of the nozzle is arranged at an angle to the plane of the film, and its air outlet length is adapted to the width of the film.

[0031] Preferably, the film receiving mechanism includes a drive housing and a film drive shaft, an LED light, an LED light adjustment switch, and an encoder mounted on the front of the drive housing. The LED light is located at the bottom of the film and parallel to the film. The film drive shaft and the encoder are electrically connected to the control unit.

[0032] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a roll-type photosensitive film developing and processing structure and a roll-type photosensitive film developing and processing machine having the same structure, which has the following beneficial effects:

[0033] 1. The liquid level of this invention remains constant during the rinsing process, making the liquid level a constant variable. The reaction time between the film and the liquid can be adjusted by changing the film movement speed, thereby optimizing the film output effect.

Detailed Implementation

[0063] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0064] Example 1

[0065] See appendix Figure 1-4 This utility model discloses a roll-type photosensitive film developing structure, including: a lifting frame 24, a film guide 23, a liquid tank 21, and a one-way circulation section 25;

[0066] The film guide 23 is installed on the lifting end 241 of the lifting frame 24; two or more medicine tanks 211 are arranged in the inner cavity of the medicine tank 21 along the film advancing direction;

[0067] Each medicine tank 211 has a partition 2110 inside, which divides it into a main medicine tank 2111 and an auxiliary medicine tank 2112. The upper end of the partition 2110 is provided with an overflow channel for the main medicine tank 2111 to flow to the auxiliary medicine tank 2112. The film guide part 23 is arranged corresponding to the main medicine tank 2111. The one-way circulation part 25 connects the bottom of the main medicine tank 2111 and the auxiliary medicine tank 2112 with the opening end of the main medicine tank 2111. The liquid flows only out of the bottom of the main medicine tank 2111 and the auxiliary medicine tank 2112. It can connect to the opening end of the main medicine tank 2111 for one-way flow. And through the overflow channel, a circulation path is formed that can ensure the liquid level of the main medicine tank 2111 and realize rapid mixing.

[0068] In this embodiment, the bottom of the medicine tank 211 is inclined from the partition plate 2110 to both ends, and the one-way circulation part 25 is located at the lowest point of the bottom of the medicine tank 211, thereby reducing the residue of medicine in the medicine tank 211.

[0069] Specifically, it may also include a water rinsing tank 22, which is located in front of the liquid tank 21 along the film movement direction 203.

[0070] To further optimize the above technical solution, the one-way circulation section 25 includes a main drug liquid outlet circulation pipe 251, an auxiliary drug liquid outlet circulation pipe 252, a circulation connecting pipe 253, a one-way valve 254, and a circulation pump 255. The inlet end of the main drug liquid outlet circulation pipe 251 is connected to the bottom of the main drug liquid tank 2111 and is in communication with it; the inlet end of the auxiliary drug liquid outlet circulation pipe 252 is connected to the bottom of the auxiliary drug liquid tank 2112 and is in communication with it; one end of the circulation connecting pipe 253 is connected to the outlet ends of the main drug liquid outlet circulation pipe 251 and the auxiliary drug liquid outlet circulation pipe 252, and the other end is connected to the upper part of the main drug liquid tank 2111; the one-way valve 254 is installed on the auxiliary drug liquid outlet circulation pipe 252 and its liquid flow direction is from the inlet end to the outlet end of the auxiliary drug liquid outlet circulation pipe 252; the circulation pump 255 is installed on the circulation connecting pipe 253.

[0071] Therefore, the medicinal liquid in the main medicinal liquid tank 2111 and the auxiliary medicinal liquid tank 2112 is transferred to the main medicinal liquid tank 2111 by the circulation pump 255. Since a one-way valve 254 is installed on the auxiliary medicinal liquid outlet circulation pipe 252, the arrangement of the one-way valve 254 prevents the medicinal liquid in the main medicinal liquid tank 2111 from entering the auxiliary medicinal liquid tank 2112 through the main medicinal liquid outlet circulation pipe, thus maintaining the height difference of the medicinal liquid levels in the main medicinal liquid tank 2111 and the auxiliary medicinal liquid tank 2112. On the one hand, the circulating pump 255 draws the liquid from the main liquid tank 2111 and the auxiliary liquid tank 2112, which results in the circulating pump 255 drawing less liquid from the main liquid tank 2111 than the amount of liquid injected into the upper part of the main liquid tank 2111. This ensures that the liquid in the main liquid tank 2111 is always overflowing into the auxiliary liquid tank 2112, keeping the liquid level constant. This makes the film quality controllable during the developing process and makes the film developing quality more stable.

[0072] Specifically, the circulation pump 255 is a peristaltic pump. Therefore, the functions of circulating and recovering the medicine solution can be achieved during the forward and reverse switching of the peristaltic pump.

[0073] Specifically, the one-way circulation section 25 may also include a first solenoid valve 256. The first solenoid valve 256 is installed on the circulation connecting pipe 253 between the main medicine liquid outlet circulation pipe 251 and the circulation pump 255 to simultaneously return the liquid in the main medicine liquid tank 2111 and the auxiliary medicine liquid tank 2112 from their bottoms to the top of the main medicine liquid tank 2111. Thus, the first solenoid valve 256 can switch the connection between the main medicine liquid tank 2111, the auxiliary medicine liquid tank 2112 and the circulation pump 255 to control the circulation time of the medicine liquid.

[0074] Specifically, the one-way circulation unit 25 may further include a medicine tank 257, which is connected to the circulation connection pipe 253 between the circulation pump 255 and the first solenoid valve via a connecting pipe 258. Specifically, it also includes a second solenoid valve 259, which is installed on the connecting pipe 258. More specifically, the liquid level in the medicine tank 257 is lower than the bottom of the main medicine tank 2111 and the auxiliary medicine tank 2112. Therefore, the medicine in the main medicine tank 2111 and the auxiliary medicine tank 2112 can be recovered into the medicine tank 257 by gravity, resulting in a simple structure and easy operation.

[0075] More specifically, the one-way circulation section 25 may also include a filter box, which is installed at the upper inlet of the main medicine tank 2111 and located at the other end of the circulation connecting pipe 253.

[0076] In some specific examples, a water heating tank 213 may also be included, with a medicine tank 211 located inside the water heating tank 213. A space is provided between the outer wall of the medicine tank 211 and the inner wall of the water heating tank 213 to accommodate the temperature-controlled liquid. Specifically, a water heating tank circulation section and a water heating tank heating section are provided at the bottom of the water heating tank 213. Thus, the medicine tank 211 is completely immersed in the water heating tank, resulting in a more uniform temperature and faster heating.

[0077] The chemical tanks may include developing agent tanks, stop developing agent tanks, and fixer agent tanks, all immersed in a water-heated tank. Heat is transferred through the warm water in the water-heated tank to heat the various chemicals in each tank. The temperature of the chemicals in each tank is controlled by regulating the temperature of the warm water in the water-heated tank, ensuring a stable and consistent temperature across all tanks. The water-heated tank uses circulating heated water, heating the chemicals through heat conduction.

[0078] See appendix Figure 5-10 The film guide 23 is detachably mounted on the lifting end 241 of the lifting frame 24. This detachable design of the film guide facilitates subsequent cleaning and maintenance.

[0079] To further optimize the above technical solution, the film guide section 23 includes a connecting frame 231, three or more film guide frames 232, and a film guide shaft assembly 111. The connecting frame 231 is detachably connected to the lifting end 241 of the lifting frame 24. The three or more film guide frames 232 are sequentially fixed on the connecting frame 231 along the film movement direction 203. The film guide shaft assembly 111 is detachably and rotatably connected to the corresponding film guide frames 232 to guide the film 200. Thus, the three or more film guide frames 232 and the film guide shaft assembly 111 corresponding to the film guide frames 232 correspond to multiple chemical tanks 211 and water rinsing tanks 22, respectively, so that the film is sequentially immersed in different chemical solutions on the film guide section 23 to complete the film rinsing, and then the residual chemical solution on its surface is rinsed in the water rinsing tank 22. This method has a high degree of integration and high efficiency. The connecting frame 231 and the guide plate shaft assembly 111 are assembled and connected to the lifting end 241 of the lifting frame 24, which is easy to disassemble. The whole material is made of lightweight material that is resistant to chemical corrosion and rust, which is convenient for quick disassembly, rinsing, and soaking, and easy to clean.

[0080] The water rinsing tank 22 ensures a sufficient flow of clean water and a stable temperature. In order to increase the film rinsing cycle, two sets of guide shafts 111 can be set in the water rinsing tank, which increases the time cycle of film immersion in water.

[0081] The water rinsing tank 22 can be divided into a main tank and an auxiliary tank. The water capacity of the main tank is smaller than that of the auxiliary tank. The two tanks are separated by a non-enclosed partition. Water can overflow from the bottom of the non-enclosed partition of the main tank to the auxiliary tank. The drain outlet of the auxiliary tank is connected to a water outlet pipe. The upper water outlet pipe is fixed to the water outlet of the auxiliary tank with a spiral joint. The water level of the main tank and the auxiliary tank in the water rinsing tank is the same. The water level is controlled by rotating the height of the upper water outlet pipe.

[0082] Clean water is introduced into the main tank to dilute any residual chemicals on the film. It then flows into the auxiliary tank from below a partially enclosed partition and is drained through an upper outlet pipe above the water surface to a lower drain pipe. Since the main tank's water capacity is smaller than the auxiliary tank's, clean water is continuously added to the main tank's inlet. To maintain the cleanliness of the water in the main tank and ensure unidirectional flow, the water in the main tank continuously flows into the auxiliary tank without stopping, diluting any remaining chemicals on the film.

[0083] All guide shaft assemblies 111 in this invention are non-powered shafts. The film experiences little resistance as it passes through the guide shaft assemblies 111, and the film is in a relatively loose state. This avoids situations such as the film getting tangled during movement and also reduces the chance of the film being scratched by the guide shafts.

[0084] To further optimize the above technical solution, the guide plate holder 232 includes a first guide plate holder 2321 corresponding to each medicine tank 211 and a second guide plate holder 2322 corresponding to the water rinsing tank 22. The first guide plate holder 2321 corresponds to the main medicine tank 2111.

[0085] The guide shaft assembly 111 is detachably and rotatably connected to the guide frame 232. The guide shaft assembly 111 includes multiple guide shafts 100 forming an upper guide shaft 112 and a lower guide shaft 113. Each lower guide shaft 113 is located on the perpendicular bisector of the line connecting two adjacent upper guide shafts 112. Depending on the arrangement of the guide shaft assembly 111, the film can be wound in a W-shape. The upper film shaft can contact the photosensitive coating surface of the film, and the lower film shaft can contact the back of the film. This ensures that the photosensitive film is immersed in the solution and its back contacts the film shaft, preventing scratches on the photosensitive coating surface.

[0086] It may also include a sponge roller assembly, which is rotatably mounted on the film guide frame and arranged below the upper film guide shaft 112 where the film is output.

[0087] The film guide frame 232 is divided into a first film guide frame 2321 and a second film guide frame 2322 corresponding to the medicine tank 211 and the water rinsing tank 22. The length or number of the film guide frames can be changed according to the needs of different functional areas, which also facilitates later maintenance and cleaning. The lower film guide shaft 113 of the film guide shaft assembly 111 is located on the vertical line of the line connecting two adjacent upper film guide shafts 112, which changes the direction of film movement, so that the film can be immersed in the medicine tank 211 or the water rinsing tank 22.

[0088] To further optimize the above technical solution, the guide shaft 100 includes a shaft body and two radially protruding annular first film mating portion 102 and second film mating portion 103 at both ends of the outer surface of the shaft body along the axial direction. The first film mating portion 102 and second film mating portion 103 at both ends are distributed in a mirror symmetrical manner relative to the center of the guide shaft. The two ends of the film 200 in the width direction can be engaged with the second film mating portion 103 or the first film mating portion 102 for transmission, and a gap is reserved between the image position and the shaft body.

[0089] Therefore, the image position of the film 200 does not come into contact with the body of the guide shaft 100 during the film's movement, thus avoiding scratches on the image surface of the film 200 due to contact.

[0090] Specifically, the guide shaft 100 has a guide shaft hole 104 extending through both ends at the central axis position, and bearing mounting slots 101 can be provided at both end faces.

[0091] In this embodiment, the guide shaft 100 is equidistantly arranged on the upper guide shaft 1111 along the film movement direction 203. The film is wound around the first guide shaft of the lower guide shaft 1112 in sequence from the first guide shaft of the upper guide shaft 1111, and then around the second guide shaft of the upper guide shaft 1111, and so on.

[0092] The specific principle and usage of the roll-type photosensitive film developing and processing structure provided in this embodiment are as follows:

[0093] 1. Control the lifting frame 24 to raise the film guide section 23;

[0094] 2. The film enters through the upper guide shaft 112 at the inlet of the film guide frame 232, passes through the lower guide shaft 113, and exits through the upper guide shaft 112 at the outlet of the film guide frame 232. The film is wound sequentially on multiple film guide frames in this order along the film movement direction 203.

[0095] 3. Control the lifting frame 24 to lower the film guide 23 into the medicine tank 21 and the water rinsing tank 22.

[0096] Example 2

[0097] See appendix Figure 11-12 According to an embodiment of the present invention, a roll-type photosensitive film processing and developing machine includes: a housing 1, the roll-type photosensitive film processing and developing structure described in Embodiment 1, a drying unit 3, a film output mechanism 4, a film take-up mechanism 5, and a control unit 6.

[0098] The top of the box 1 is provided with an openable cover 11, and its opposite side walls are respectively provided with a film inlet and a film outlet;

[0099] The roll-type photosensitive film developing and processing structure is located inside the box 1, and the chemical solution tank 21 is arranged on the side corresponding to the film inlet.

[0100] The drying section 3 is located inside the housing 1 and is in front of the water rinsing tank 22 along the film movement direction 203;

[0101] The film output mechanism 4 is arranged on the outer wall of the housing 1 and corresponds to the film inlet;

[0102] The film receiving mechanism 5 is arranged on the outer wall of the housing 1 and corresponds to the film outlet;

[0103] The control unit 6 is electrically connected to the film output mechanism 4 and the film receiving mechanism 5.

[0104] Specifically, square barrel-shaped windows extending into the interior of the box 1 are provided at the film inlet and film outlet positions; this reduces the amount of ambient light entering the interior of the box 1.

[0105] See appendix Figure 13-14 The film output mechanism 4 includes a light-shielding box 41 and a film driven shaft 42 and a film sensing part 43 installed inside the light-shielding box 41. The outlet of the light-shielding box 41 corresponds to the film inlet of the box 1.

[0106] The film sensing unit 43 includes a support rail 432, a sliding bracket 431, a photoelectric switch 433, and a guide sleeve shaft 434. The support rail 432 is fixed to the inner wall of the light-shielding box 41 along its height direction. One end of the sliding bracket 431 is vertically slidably connected to the support rail 432. The guide sleeve shaft 434 is fixedly sleeved on the sliding bracket 431 and can abut against the upper surface of the horizontally conveyed film 200. The photoelectric switch 433 is electrically connected to the control unit 6 and is located at the bottom of the support rail 432. It can sense the sliding state of the sliding bracket 431 and control the film take-up mechanism 5 to stop operating through the control unit 6. Thus, the mechanical film sensing unit avoids the influence on the film caused by direct contact between the optical inspection equipment and the film.

[0107] In this embodiment, after the film receiving mechanism 5 stops operating, the tail of the film remains in the light-shielding box 41, thereby facilitating the connection of the next batch of film for further processing.

[0108] See appendix Figure 15 The drying unit 3 includes a drying chamber 31 and a film blowing structure 32 and a heating unit 33 installed inside the drying chamber 31.

[0109] In this embodiment, the drying chamber 31 is a closed structure with an opening on the front, and the front of the drying chamber 31 has an openable door panel arranged on the chamber 1.

[0110] In this embodiment, the drying chamber 31 is connected to the roll-type photosensitive film developing structure 2 through a square film channel. A film light shield is arranged at the end of the film channel inside the drying chamber 31. Specifically, the drying chamber 31 is also equipped with a temperature sensor, which is electrically connected to the controller 6. Thus, the controller 6 can monitor the temperature inside the drying chamber 31 in real time and achieve the optimal temperature required for film drying by controlling the heating unit 33.

[0111] See appendix Figure 16-18 The film blowing structure 32 includes two nozzles 321 arranged in a pincer shape and a Y-shaped ventilation duct 322. The two nozzles 321 are connected to two branch pipes of the Y-shaped ventilation duct 322, and the air outlet of the nozzles 321 is strip-shaped. Thus, the pincer-shaped nozzles 321 and the strip-shaped air outlet of the nozzles 321 increase the air speed at the air outlet and more effectively remove water stains from the film surface.

[0112] In this embodiment, a mounting plate is provided inside the drying chamber 31. The mounting plate has multiple mounting holes. The ends of two branch pipes of the Y-shaped ventilation duct 322 are fixed at two of the mounting holes. More specifically, a connecting locking ring 323 is also provided. The connecting locking ring 323 has multiple locking holes to lock the main pipes of the multiple Y-shaped ventilation ducts 322. Therefore, the number of film blowing structures 32 can be increased or decreased according to requirements.

[0113] In this embodiment, guide shafts 100 are arranged at both ends of the film blowing structure, and the guide shafts 100 are detachably connected to the drying chamber 31. This detachable connection facilitates subsequent cleaning, maintenance, and replacement.

[0114] See appendix Figures 19-20 The film blowing structure 32 has two nozzles 321 whose outlets correspond to the two side surfaces of the image surface of the film 200. The length direction 201 of the nozzle outlet is arranged at an angle to the film movement direction 203; the blowing direction 202 of the nozzle outlet is arranged at an angle to the film plane, and its outlet length is adapted to the width of the film 200. Therefore, the outlets of the nozzles 321 correspond to the two side surfaces of the image surface of the film 200, allowing for simultaneous removal of water stains from both sides of the film 200 with higher efficiency. Simultaneously, the angular arrangement increases the contact area between the air and the film 200, preventing water stains from accumulating on the film 200 surface, resulting in high efficiency and stronger water stain removal capability.

[0115] In this embodiment, the length direction 201 of the nozzle's air outlet is arranged at a 45-degree angle to the film movement direction 203, the air blowing direction 202 of the nozzle's air outlet is arranged at a 45-degree angle to the film plane, and the length of its air outlet is adapted to the width of the film 200.

[0116] See appendix Figure 21The film receiving mechanism 5 includes a drive housing 51 and a film drive shaft 52, an LED light 53, an LED light adjustment switch 54, and an encoder 55 mounted on the front of the drive housing 51. The LED light 53 is located at the bottom of the film 200 and parallel to the film 200. The film drive shaft 52 and the encoder 55 are electrically connected to the control unit 6. Thus, the LED light 53 located on the bottom surface of the film 200 makes it easier for the operator to monitor the quality of the film after development. The encoder detects the running speed of the film 200 in real time, and adjusts the rotation speed of the film drive shaft 52 according to the quality through the control unit 6.

[0117] The specific principle and usage of the roll-type photosensitive film developing and processing machine provided in this embodiment are as follows:

[0118] 1. Install the roll of film onto the film driven shaft 42 inside the film output mechanism 4;

[0119] 2. Open the machine cover 11 and raise the film guide section 23;
