Description

Technical Field

[0001] This utility model relates to the technical field of film rolling machine equipment, and specifically to an intelligent fault alarm device suitable for film rolling machines. Background Technology

[0002] The invention of the professional film developing machine was a product of the standardization and industrialization needs of photographic technology and the evolution of the market (commercial mass production and niche personalization). Its development has witnessed the transformation of film photography from manual to automated, and from mass to niche. It continues to play a key role in professional developing and film enthusiast communities, and is an indispensable part of the history of imaging technology.

[0003] In related technologies, professional film developing machines integrate developing, bleaching, fixing, and stabilizing processes. The film is placed inside the machine, and internal gears and other transmission mechanisms drive the lead film and the film through various chemical tanks at a constant speed. The lead film enters the machine first, then the film sequentially passes through the developing tank, bleaching tank, fixing tank, and stabilizing tank. The chemicals stored in the chemical cylinders connected to the bottom of each tank have different functions: developing reveals latent images on the film, bleaching removes silver images (for color negatives), fixing fixes the image, and stabilizing makes the film more durable. During transport, the machine automatically controls the film's movement speed to ensure the dwell time in each chemical tank meets the processing requirements. For example, the Noritsu QSF-30S developing machine uses a specific C-41 process, with precise time and temperature control, allowing for stable film developing and restoring the film's color accuracy.

[0004] However, its fault alarm device has defects. When the liquid in the dosing cylinder is almost used up, the equipment will alarm to remind the personnel, who will then manually add the prepared liquid into the cylinder and manually turn off the alarm button. If the operator does not hear the alarm or is unable to add liquid because they are operating other equipment, the equipment will run out of liquid, causing unnecessary losses and resulting in a low level of intelligence in the equipment. To solve the above problems, an intelligent fault alarm device suitable for film processing machines is proposed to solve the above problems. Utility Model Content

[0005] In view of this, the present invention provides an intelligent fault alarm device suitable for film developing machines. The present invention uses a high liquid level gauge to provide feedback on the high liquid level signal of the filling cylinder and a low liquid level gauge to provide feedback on the low liquid level signal of the filling cylinder. When the liquid level in the filling cylinder is low, the electric valve automatically opens, allowing the liquid from the replenishment cylinder to be replenished into the filling cylinder in an emergency. At the same time, an audible and visual alarm alerts the operator, and the specific alarm unit can be identified through the alarm indicator light group. Thus, the operator does not need to replenish the liquid immediately, improving the intelligence of the equipment.

[0006] To solve the above-mentioned technical problems, this utility model provides an intelligent fault alarm device suitable for film developing machines, including a liquid storage tank at the bottom of the developing machine, a door panel on one side of the liquid storage tank, a maintenance panel on the other side of the liquid storage tank, an operating base at the front of the developing machine, an operating panel on the top of the operating base, an audible and visual alarm on one side of the operating panel, an alarm indicator light group on the other side of the operating panel, multiple liquid filling cylinders in the liquid storage tank, each liquid filling cylinder having a first liquid level group, a water replenishment tank in the liquid storage tank near the operating base, and a second liquid level group on the water replenishment tank.

[0007] Each liquid filling cylinder has a replenishment cylinder on the side near the door panel. The replenishment cylinder is used to store the liquid used in different rolling processes, and is also used to replenish the liquid in the liquid filling cylinder on the same side after an alarm is triggered. Each replenishment cylinder has a filling nozzle on the top side near the door panel. The filling nozzle is used to manually replenish the liquid in the replenishment cylinder.

[0008] Each replenishment cylinder has a connecting pipe at the bottom of its side away from the door panel. The connecting pipe connects the bottom of the replenishment cylinder to the bottom of the filling cylinder. When the filling cylinder has a low liquid level, the electric valve can be opened to automatically replenish the filling cylinder through the replenishment cylinder. The other end of the connecting pipe is connected to the filling cylinder. Each connecting pipe is equipped with an electric valve to control the opening and closing of the connecting pipe, thereby controlling when the replenishment cylinder replenishes the filling cylinder.

[0009] Each filling cylinder has a label on the top side near the door panel. The label is used to indicate the abbreviation of the name of the liquid in each filling cylinder, so as to prevent personnel from adding the wrong liquid. Each label has a main flashing light on its side wall. The main flashing light is connected to the low liquid level gauge, so the main flashing light flashes when the low liquid level gauge sends a feedback signal.

[0010] Each first liquid level group includes a high liquid level gauge and a low liquid level gauge. The high liquid level gauge is located on the side of the same-side filling cylinder closest to the door panel, and the low liquid level gauge is located on the side of the same-side filling cylinder furthest from the door panel. The high liquid level gauge is used to detect the high liquid level signal of the filling cylinder, and the low liquid level gauge is used to detect the low liquid level signal of the filling cylinder. When the liquid level in the filling cylinder is low, the electric valve automatically opens, allowing the medicine in the replenishment cylinder to be replenished in an emergency. After the emergency replenishment, the medicine in the replenishment cylinder can be manually replenished by opening the filling nozzle. At this time, the electric valve is in the open state, connecting the replenishment cylinder and the filling cylinder. When the high liquid level signal of the filling cylinder is detected, the electric valve closes, thus forming a closed loop, so that the operator does not need to replenish the medicine immediately.

[0011] The second level group includes an upper level gauge and a lower level gauge. The upper level gauge is used to detect the high level signal of the water replenishment tank, and the lower level gauge is used to detect the low level signal of the water replenishment tank. The upper level gauge is located on the side of the water replenishment tank closest to the door panel, and the lower level gauge is located on the side of the water replenishment tank furthest from the door panel.

[0012] The alarm indicator group includes multiple secondary flashing lights, which are used to follow the flashing of the main flashing light. Each main flashing light is electrically connected to one secondary flashing light, and the main flashing light and the secondary flashing light flash the same color.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. The system uses a high-level gauge to provide feedback on the high-level signal of the filling cylinder and a low-level gauge to provide feedback on the low-level signal. When the filling cylinder reaches a low level, the electric valve automatically opens, allowing the medicine in the replenishment cylinder to be replenished in an emergency. After emergency replenishment, the medicine in the replenishment cylinder can be manually replenished by opening the filling nozzle. At this time, the electric valve is open, connecting the replenishment cylinder and the filling cylinder. When the high-level signal of the filling cylinder is detected, the electric valve closes, forming a closed loop. This eliminates the need for operators to replenish the medicine immediately. Simultaneously, when the filling cylinder alarms for a low level, its corresponding main flashing light flashes, and the corresponding auxiliary flashing light also flashes. The audible and visual alarm also flashes synchronously, allowing for emergency replenishment while alerting personnel to the alarm. This avoids the need for operators to perform two tasks simultaneously without interference, thus improving the intelligence of the equipment.

[0015] 2. The upper level gauge is used to detect the high level signal of the water supply tank, and the lower level gauge is used to detect the low level signal of the water supply tank. When the lower level gauge detects a low level signal, the water supply pump is started to supply water to the water supply tank. When the upper level gauge detects a high level, the water supply pump stops and the water supply pipeline is closed. Thus, water can be automatically replenished when the water supply tank level alarm is triggered, which improves the intelligence of the equipment.

[0016] 3. The label is used to indicate the abbreviation of the name of the liquid in each liquid filling cylinder, so as to prevent personnel from adding the wrong liquid. The main flashing light is connected to the low liquid level gauge, so the main flashing light flashes when the low liquid level gauge sends a feedback signal. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-7 The technical solutions of the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0026] like Figure 1-7As shown: This embodiment provides an intelligent fault alarm device suitable for film developing machines, including a liquid storage tank 100 at the bottom of the developing machine, a door panel 101 on one side of the liquid storage tank 100, the door panel 101 being connected to the liquid storage tank 100 via a hinge, a maintenance plate 102 on the other side of the liquid storage tank 100, the maintenance plate 102 having a split upper and lower structure and being bolted to the liquid storage tank 100, an operating base 103 at the front end of the developing machine, the operating base 103 being vertically fixed at the front end of the developing machine, an operating panel 104 on the top of the operating base 103, the operating panel 104 being fixedly installed on the inclined surface of the top of the operating base 103, an audible and visual alarm 200 on one side of the operating panel 104, the audible and visual alarm 200 being electrically connected to an alarm indicator light, the audible and visual alarm 200 using alternating red and yellow flashing lights, the audible and visual alarm 200... The alarm will sound an alarm. An alarm indicator group 201 is provided on the other side of the operation panel 104. The alarm indicator group 201 is used to gather multiple different auxiliary flashing lights 202 together. A voice broadcaster can be provided at the bottom of the alarm indicator group 201. The voice broadcaster can announce the name of the triggered main flashing light 307. Multiple liquid filling cylinders 300 are provided in the liquid storage tank 100. The bottom of the liquid filling cylinder 300 is provided with a groove to place the liquid filling cylinder 300 and prevent it from shaking. Each liquid filling cylinder 300 is provided with a first liquid level group 301. The first liquid level group 301 is used to detect the liquid level in the liquid filling cylinder 300. A water replenishment tank 400 is provided on the side of the liquid storage tank 100 near the operation base 103. The water replenishment tank 400 is used to store clean water. A second liquid level group 401 is provided on the water replenishment tank 400. The second liquid level group 401 is used to detect the liquid level in the liquid replenishment cylinder 302.

[0027] In operation, the high-level gauge 309 provides feedback on the high-level signal of the filling cylinder 300, and the low-level gauge 308 provides feedback on the low-level signal of the filling cylinder 300. When the filling cylinder 300 reaches a low level, the electric valve 305 automatically opens, allowing the medicine in the replenishment cylinder 302 to be replenished into the filling cylinder 300 in an emergency. After emergency replenishment, the medicine in the replenishment cylinder 302 can be manually replenished by opening the filling nozzle 303. At this time, the electric valve 305 is open, connecting the replenishment cylinder 302 and the filling cylinder 300. When the high-level signal of the filling cylinder 300 is detected, the electric valve 305 closes, forming a closed loop. This eliminates the need for immediate replenishment by the operator. Simultaneously, when the filling cylinder 300 triggers a low-level alarm, its corresponding main flashing light flashes, and the corresponding auxiliary flashing light 202 also flashes. The audible and visual alarm 200 also flashes synchronously, allowing for emergency replenishment while simultaneously alerting the operator to the alarm. This avoids the need for the operator to perform two tasks at the same time, thus improving the intelligence of the equipment.

[0028] This embodiment provides an intelligent fault alarm device suitable for film processing machines.

[0029] like Figure 2 , 3 As shown in Figures 4 and 5: Each liquid filling cylinder 300 is provided with a replenishing cylinder 302 on the side near the door panel 101. The replenishing cylinder 302 is placed on the bottom plate inside the liquid storage chamber 100. The replenishing cylinder 302 is used to store different liquids used during rolling and is also used to replenish the liquid after the alarm of the liquid filling cylinder 300 on the same side.

[0031] like Figure 2 , 5 As shown: Each replenishment cylinder 302 has a connecting pipe 304 on the side of its bottom away from the door panel 101. The connecting pipe 304 is used to connect the bottom of the replenishment cylinder 302 to the bottom of the filling cylinder 300. The connecting pipe 304 and the replenishment cylinder 302 are heat-fused together. When the filling cylinder 300 has a low liquid level, the electric valve 305 can be opened to automatically replenish the filling cylinder 300 through the replenishment cylinder 302. The other end of the connecting pipe 304 is heat-fused together with the filling cylinder 300. Each connecting pipe 304 is equipped with an electric valve 305. The electric valve 305 and the connecting pipe 304 can be connected by a flange or thread seal. The electric valve 305 is used to control the opening and closing of the connecting pipe 304, thereby controlling when the replenishment cylinder 302 replenishes the filling cylinder 300.

[0032] Its effect is as follows: the connecting pipe 304 is used to connect the bottom of the replenishing cylinder 302 and the filling cylinder 300. When the filling cylinder 300 has a low liquid level, the electric valve 305 can be opened to automatically replenish the filling cylinder 300 through the replenishing cylinder 302. The electric valve 305 is used to control the opening and closing of the connecting pipe 304, thereby controlling when the replenishing cylinder 302 replenishes the filling cylinder 300.

[0033] like Figure 2 , 3As shown in Figures 4, 5, and 6: Each liquid filling cylinder 300 has a label 306 on the top side near the door panel 101. The label 306 can be heat-fused to the liquid filling cylinder 300. The label 306 is used to mark the abbreviation of the name of the liquid in each liquid filling cylinder 300, so as to prevent personnel from adding the wrong liquid. Each label 306 has a main flashing light 307 on its side wall. The main flashing light 307 and the label 306 can be fixed by bolts. The main flashing light 307 is connected to the low liquid level gauge 308, so the main flashing light 307 flashes when the low liquid level gauge 308 sends a feedback signal.

[0034] Its effect is as follows: the nameplate 306 is used to mark the abbreviation of the name of the medicine liquid on each liquid filling cylinder 300, so as to prevent personnel from adding the wrong liquid. The main flashing light 307 is connected to the low liquid level gauge 308, so the main flashing light 307 flashes when the low liquid level gauge 308 sends a feedback signal.

[0035] like Figure 2 , 3 As shown in Figures 4, 5, and 6: Each first liquid level group 301 includes a high liquid level gauge 309 and a low liquid level gauge 308. The high liquid level gauge 309 and the filling cylinder 300 can be connected by adhesive, and the low liquid level gauge 308 and the filling cylinder 300 can be connected by adhesive. The high liquid level gauge 309 is located on the side of the filling cylinder 300 closest to the door panel 101, and the low liquid level gauge 308 is located on the side of the filling cylinder 300 furthest from the door panel 101. The high liquid level gauge 309 is used to detect the high liquid level signal of the filling cylinder 300, and the low liquid level gauge 308... The device is used to detect the low liquid level signal of the filling cylinder 300. When the liquid level in the filling cylinder 300 is low, the electric valve 305 automatically opens, so that the medicine in the replenishment cylinder 302 is replenished into the filling cylinder 300 in an emergency. After the emergency replenishment, the medicine in the replenishment cylinder 302 is manually added by opening the filling nozzle 303. At this time, the electric valve 305 is in the open state and the replenishment cylinder 302 is connected to the filling cylinder 300. When the high liquid level signal of the filling cylinder 300 is detected, the electric valve 305 closes, thus forming a closed loop, so that the operator does not need to replenish the medicine immediately.

[0036] The effect is as follows: the high level gauge 309 is used to detect the high level signal of the filling cylinder 300, and the low level gauge 308 is used to detect the low level signal of the filling cylinder 300. When the filling cylinder 300 is at a low level, the electric valve 305 automatically opens, so that the medicine in the replenishment cylinder 302 is replenished into the filling cylinder 300 in an emergency. After emergency replenishment, the medicine in the replenishment cylinder 302 is manually added by opening the filling nozzle 303. At this time, the electric valve 305 is in the open state and the replenishment cylinder 302 is connected to the filling cylinder 300. When the high level signal of the filling cylinder 300 is detected, the electric valve 305 closes, thus forming a closed loop, so that the operator does not need to replenish the medicine immediately.

[0037] like Figure 2 ,3 As shown in Figures 4 and 5: The second liquid level group 401 includes an upper liquid level gauge 402 and a lower liquid level gauge 403. The upper liquid level gauge 402 and the water supply tank 400 can be connected by adhesive, and the lower liquid level gauge 403 and the water supply tank 400 can be connected by adhesive. The upper liquid level gauge 402 is used to detect the high liquid level signal of the water supply tank 400, and the lower liquid level gauge 403 is used to detect the low liquid level signal of the water supply tank 400. The upper liquid level gauge 402 is located on the side of the water supply tank 400 near the door panel 101, and the lower liquid level gauge 403 is located on the side of the water supply tank 400 away from the door panel 101. A water supply pipe is provided on the side of the water supply tank 400 near the inspection plate 102. A valve is provided on the water supply pipe. The water supply pipe and the water supply tank 400 can be connected by a threaded seal. A water supply pump is provided through the water supply pipe and the water supply pipe. The water supply pump and the water supply pipe can be connected by a flange seal. The water supply pump inlet is connected to the water source by a pipe seal.

[0038] Its effect is as follows: the upper level gauge 402 is used to detect the high level signal of the water supply tank 400, and the lower level gauge 403 is used to detect the low level signal of the water supply tank 400. When the low level signal of the lower level gauge 403 is detected, the water supply pump is started to supply water to the water supply tank 400. When the upper level gauge 402 detects the high level, the water supply pump stops and the water supply pipeline is closed. Thus, water can be automatically replenished when the water supply tank 400 alarms, which improves the intelligence of the equipment.

[0039] like Figure 5 , 7 As shown: The alarm indicator group 201 includes multiple auxiliary flashing lights 202. The auxiliary flashing lights 202 and the main flashing light 307 can be connected wirelessly or both can be connected to the operating base 103 via wires. The auxiliary flashing lights 202 are used to follow the flashing of the main flashing light 307. Each main flashing light 307 is electrically connected to one auxiliary flashing light 202. The main flashing light 307 and the auxiliary flashing light 202 flash in the same color. A support frame is provided in the upper part of the liquid storage tank 100. The support frame is welded to the inner wall of the liquid storage tank 100. A water replenishment pump and multiple liquid replenishment pumps are provided in the support frame. The water replenishment pumps are connected to the water replenishment tank 400. Each liquid replenishment pump is connected to its corresponding liquid filling cylinder 300.

[0040] Its effect is as follows: the secondary flashing light 202 is used to follow the flashing of the main flashing light 307, and each main flashing light 307 is electrically connected to a secondary flashing light 202.

[0041] Working principle: When the liquid level is low and an alarm is triggered, the high liquid level gauge 309 sends a high liquid level signal to the filling cylinder 300, and the low liquid level gauge 308 sends a low liquid level signal to the filling cylinder 300. Consequently, when the liquid level in the filling cylinder 300 is low, the electric valve 305 automatically opens, allowing the liquid in the replenishment cylinder 302 to be replenished into the filling cylinder 300 in an emergency. After the emergency replenishment, the liquid in the replenishment cylinder 302 is manually added by opening the filling nozzle 303. At this time, the electric valve 305 is open, connecting the replenishment cylinder 302 and the filling cylinder 300. When the liquid in the filling cylinder... When a high liquid level signal of 300 is detected, the electric valve 305 closes, forming a closed loop. This eliminates the need for immediate liquid replenishment by the operator. Simultaneously, when a low liquid level alarm is triggered, the main flashing light of the liquid filling cylinder 300 flashes, and the corresponding auxiliary flashing light 202 also flashes. The audible and visual alarm 200 also flashes synchronously. This allows for emergency liquid replenishment while alerting the operator to the alarm, avoiding the need for the operator to perform two tasks simultaneously without interference, thus improving the intelligence of the equipment.

[0042] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0043] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
