Description

Technical Field

[0001] This utility model relates to a chemical solution circulation system, specifically a roll-type film developing chemical solution circulation system, belonging to the field of photosensitive film developing equipment. Background Technology

[0002] Existing roll-type photographic film processors typically include a developing tank, fixing tank, washing tank, drying chamber, blowing chamber, and heating chamber. During the processing, developing and fixing solutions are placed in the corresponding developing and fixing tanks. The film's development and fixing processes are controlled by adjusting the time and depth of immersion in these tanks. However, this method suffers from several drawbacks. The movement of the developing rack and film, along with film adhesion and the carrying of solutions, causes variations in the solution levels in the developing and fixing tanks. This results in inconsistent immersion times for the continuously moving roll of film in the developing and fixing solutions, affecting the developing and fixing results. Furthermore, chemical reactions occur during the contact between the film and the solutions, potentially impacting the performance of the solutions in certain areas.

[0003] Therefore, how to achieve consistency in the time when the film enters the developing tank and fixing tank, while ensuring uniform and stable chemical properties during the developing process, has always been a problem to be solved in the developing process of roll film. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a roll-type film developing and processing chemical solution circulation system, which solves the problems in the prior art where the chemical solution in the developing tank or / and fixing tank is lost due to the entry and exit of the developing support and film, resulting in inconsistent chemical solution processing time and uneven chemical reaction of the chemical solution.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a roll-type photosensitive film developing and processing chemical solution circulation system, including a main chemical solution tank, an auxiliary chemical solution tank, a main chemical solution outlet circulation pipe, an auxiliary chemical solution outlet circulation pipe, a circulation connecting pipe, a one-way valve and a circulation pump, wherein the upper end of the main chemical solution tank is provided with an overflow port, and the overflow port is connected to the auxiliary chemical solution tank;

[0007] The beneficial effects of this invention are as follows: By simultaneously connecting the main drug solution outlet circulation pipe and the auxiliary drug solution outlet circulation pipe to the bottom of both the main drug solution tank and the auxiliary drug solution tank, and by using a circulation pump to concentrate only into the main drug solution tank, this invention ensures that the level of the drug solution in the main drug solution tank remains constant during the uniform movement of the roll-type photosensitive film through the drug solution support. This guarantees that each part of the continuously moving film is immersed in the drug solution for a consistent time. Furthermore, the flow of the drug solution agitates the solution, improving the uniformity of contact between the film and the drug solution and enhancing the stability of the chemical reaction between the drug solution and the film.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, it also includes a first solenoid valve, which is installed on the circulation connecting pipe between the main drug solution outlet circulation pipe and the circulation pump to simultaneously return the liquid in the main drug solution tank and the auxiliary drug solution tank from their bottoms to the top of the main drug solution tank.

[0010] Furthermore, it also includes a medicine tank, which is connected to the circulation connection pipe between the circulation pump and the first solenoid valve via a connecting pipe.

[0011] Furthermore, it also includes a second solenoid valve, which is installed on the connecting pipe.

[0012] Furthermore, the liquid level in the medicine tank is lower than the bottom of the main medicine tank and the auxiliary medicine tank.

[0013] Furthermore, the main drug solution tank and the auxiliary drug solution tank are integrally formed and share a common wall panel, with the overflow port at the upper end of the wall panel.

Detailed Implementation

[0022] 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.

[0023] like Figure 1-2 As shown, the roll-type photosensitive film developing and processing chemical solution circulation system according to an embodiment of the present invention includes a main chemical solution tank 1, an auxiliary chemical solution tank 2, a main chemical solution outlet circulation pipe 3, an auxiliary chemical solution outlet circulation pipe 4, a circulation connecting pipe 6, a one-way valve 5, and a circulation pump 7. The upper end of the main chemical solution tank 1 is provided with an overflow port 131, which is connected to the auxiliary chemical solution tank 2.

[0024] The inlet end of the main drug solution outlet circulation pipe 3 is connected to the bottom of the main drug solution tank 1 and is in communication with it; the inlet end of the auxiliary drug solution outlet circulation pipe 4 is connected to the bottom of the auxiliary main drug solution tank 1 and is in communication with it; one end of the circulation connecting pipe 6 is connected to the outlet ends of the main drug solution outlet circulation pipe 3 and the auxiliary drug solution outlet circulation pipe 4, and the other end is connected to the upper part of the main drug solution tank 1; the one-way valve 5 is installed on the auxiliary drug solution outlet circulation pipe 4 and its liquid flow direction is from the inlet end to the outlet end of the auxiliary drug solution outlet circulation pipe 4; the circulation pump 7 is installed on the circulation connecting pipe 6.

[0025] Therefore, in this embodiment of the present invention, the main medicine liquid outlet circulation pipe 3 and the auxiliary medicine liquid outlet circulation pipe 4 can be combined through two channels via the circulation pump 7 to enter the main medicine liquid tank 1. At the same time, the one-way valve ensures that the medicine liquid in the main medicine liquid tank 1 will not enter the auxiliary medicine liquid tank 2 through the main medicine liquid outlet circulation pipe 3 and the auxiliary medicine liquid outlet circulation pipe 4. This ensures that the amount of medicine liquid entering the main medicine liquid tank 1 is the sum of the amount of liquid flowing out of the main medicine liquid outlet circulation pipe 3 and the auxiliary medicine liquid outlet circulation pipe 4. This fully ensures the stability of the medicine liquid level in the main medicine liquid tank 1 at the highest position. At the same time, the medicine liquid is drawn out through the main medicine liquid outlet circulation pipe 3 and the auxiliary medicine liquid outlet circulation pipe 4 and flows into the main medicine liquid tank 1 from above, ensuring the uniformity of the medicine liquid performance and minimizing the time for uniform mixing of the medicine liquid.

[0026] Specifically, it may also include a first solenoid valve 8, which is installed on the circulation connecting pipe 6 between the main drug liquid outlet circulation pipe 3 and the circulation pump 7 to simultaneously return the liquid in the main drug liquid tank 1 and the auxiliary drug liquid tank 2 from their bottoms to the top of the main drug liquid tank 1. Thus, the first solenoid valve 8 can switch the connection between the main drug liquid tank 1, the auxiliary drug liquid tank 2 and the circulation pump 7 to control the circulation time of the drug liquid.

[0027] In some specific embodiments, a medicine liquid tank 10 is included, which is connected to a circulation connection pipe 6 between the circulation pump 7 and the first solenoid valve 8 via a connecting pipe 11. Specifically, a second solenoid valve 9 is also included, which is installed on the connecting pipe 11.

[0028] Specifically, the liquid level in the medicine tank 10 is lower than the bottom of the main medicine tank 1 and the auxiliary medicine tank 2. Therefore, the medicine in the main medicine tank 1 and the auxiliary medicine tank 2 can be recovered into the medicine tank 10 by gravity. The structure is simple and easy to operate.

[0029] Specifically, the main drug solution tank 1 and the auxiliary drug solution tank 2 are integrally formed and share a wall panel 13, with an overflow port 131 at the upper end of the wall panel 13. As a result, the flow rate of the overflow port 131 can be set to be large, ensuring that the drug solution at the highest liquid level quickly overflows into the auxiliary drug solution tank 2, and ensuring the precise consistency of the highest liquid level in the main drug solution tank 1.

[0030] In some examples, a filter box 12 is also included, which is installed on the upper end of the main medicine tank 1 and whose inlet is connected to the other end of the circulation pipe 6.

[0031] Specifically, the circulation pump 7 is a peristaltic pump. Therefore, the function of circulating and recovering the medicine solution can be achieved through the forward and reverse switching of the peristaltic pump.

[0032] This utility model also provides a roll-type photosensitive film developing and processing machine, including the above-mentioned roll-type photosensitive film developing and processing chemical solution circulation system.

[0033] Furthermore, the roll-type photosensitive film developing and processing chemical solution circulation system consists of multiple sets; the main chemical solution tank and auxiliary chemical solution tank 2 in each set can respectively be the main chemical solution tank 1 and auxiliary chemical solution tank 2 of the developing tank; and the main chemical solution tank 1 and auxiliary chemical solution tank 2 of the fixing tank.

[0034] The working process of the roll-type photosensitive film developing and imaging chemical solution circulation system of this utility model:

[0035] The main medicine tank and the auxiliary medicine tank 2 are connected at the bottom by a main medicine outlet circulation pipe 3 and an auxiliary medicine outlet circulation pipe 4. The auxiliary medicine outlet circulation pipe 4 is equipped with a one-way flow valve and is connected to the top of the main medicine tank through a circulation connecting pipe 6, on which a peristaltic pump is installed to form a medicine circulation. The inlet of the peristaltic pump is connected to the bottom of the main medicine tank and the auxiliary medicine tank 2.

[0036] The second path can be connected to the medicine tank 10 located at a lower position below the main medicine tank and the auxiliary medicine tank 2, which can realize the absorption and release of medicine in the medicine tank 10 and return to the medicine tank 10.

[0037] When the second valve opens and the first valve closes, the peristaltic pump operates, creating suction; the medicine can be drawn from the medicine tank 10 into the main medicine tank; when the main medicine tank 1 is full, the medicine overflows through the baffle into the auxiliary medicine tank 2. The flow rate and velocity of the peristaltic pump can control the time of medicine extraction, thereby controlling the dosage of medicine extracted.

[0038] When the preset amount of medicine solution is drawn, the second valve is closed and the first valve is opened. The peristaltic pump continues to operate, forming a loop through which the medicine solution flowing from the main medicine solution tank 1 to the auxiliary medicine solution tank 2 is drawn back into the main medicine solution tank 1. The overflow port 131 ensures that the liquid level in the main medicine solution tank is kept at the same level as the overflow port 131, thus ensuring that the main medicine solution tank 1 is always fully loaded. By controlling the liquid level in the main medicine solution tank 1, the time each unit length of the roll-type photographic film spends in the medicine solution is consistent as it moves at a uniform speed through the medicine solution support. Simultaneously, the flow of the medicine solution agitates the solution, improving the uniformity of contact between the film and the medicine solution and enhancing the stability of the chemical reaction between the medicine solution and the film.

[0039] Once the film has been developed, open the second valve and then the first valve, causing the peristaltic pump to reverse its movement. Gravity will then allow the chemicals in the chemical tank to flow back to the lower chemical tank 10, completing the chemical recovery process. The reverse movement of the pump also promotes the complete return of any residual chemicals in the pipeline.

[0040] After all the medicine is recovered, the tube inserted into the medicine tank 10 is inserted into the drain pipe to facilitate the rinsing and cleaning of the medicine tank and medicine pipeline after the film processing is completed.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
