Description

Technical Field

[0001] This utility model relates to the field of solid aluminum electrolytic capacitor production technology, specifically to an air intake device that prevents reverse exhaust. Background Technology

[0002] The general production process of solid aluminum electrolytic capacitors is as follows: cutting → nailing and winding → welding → formation → impregnation → polymerization → assembly → aging → stamping → cutting leads or tape → external inspection and packaging → warehousing.

[0003] During the polymerization process, materials such as monomers, oxidants, and dispersions are baked at high temperatures, containing volatile substances such as anhydrous ethanol and additives. To ensure production quality, a blower at the bottom of the oven is used to blow air upwards during high-temperature baking, ensuring continuous and even heat distribution within the oven. Simultaneously, the volatile substances such as anhydrous ethanol and additives are blown towards the exhaust vents and discharged into the corresponding exhaust dust ducts. Additionally, some of the exhausted air is replenished through the air inlets on both sides of the oven.

[0004] Because the mechanical equipment inside the oven operates continuously every day, equipment failures are inevitable, such as fan blades sinking or motor reversal. When this happens, the air inlets on both sides of the oven will not be able to supply some air, and may even discharge volatile substances such as anhydrous ethanol and additives into the air. These volatile substances cannot be blown to the air outlet and discharged into the corresponding exhaust and dust collection pipes, resulting in potential quality problems in the produced products, and in severe cases, even the entire batch of products may be scrapped.

[0005] An intake device to prevent reverse exhaust is proposed in order to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide an air intake device to prevent reverse exhaust, in order to solve the problem mentioned in the background art. Currently, due to the continuous daily production and operation of the mechanical equipment inside the oven, equipment failures are inevitable, such as fan blades sinking or motor reversal. When such situations occur, the air intakes on both sides of the oven will not be able to replenish some air, and even volatile substances such as anhydrous ethanol and additives will be discharged into the air from both sides. These volatile substances cannot be blown to the air outlet and discharged into the corresponding exhaust and dust collection pipes, resulting in potential quality problems in the produced products, and in severe cases, even the scrapping of the entire batch of products.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an air intake device for preventing reverse exhaust, including an oven;

[0008] The oven has a fan at the bottom of its interior, and air inlets are symmetrically connected to both sides of the oven, while an air outlet is connected to the top of the oven.

[0010] An alarm is installed on one side of the oven, and proximity sensors are fixedly installed on both sides of the oven above the two air inlets. Indication components are installed on both sides of the oven between the proximity sensors and the air inlets.

[0011] The prompting component includes a mounting plate disposed on one side of the oven, and a fixing bracket is symmetrically mounted on one side of the mounting plate. A rotating rod is hinged between the fixing brackets, and a lightweight foam board is fixedly mounted at the bottom of the rotating rod.

[0012] The mounting plate is symmetrically mounted on both sides of the two fixed frames. A cylinder is fixedly mounted on one side of the mounting frame. A suction cup is connected through one end of the cylinder, and an air outlet is connected through one side of the cylinder. A piston is slidably connected inside the cylinder, and the piston is slidably connected to the cylinder.

[0013] Preferably, a fixed sleeve is fixedly installed on the side of the cylinder away from the suction cup, and a movable rod is slidably connected to the inside of the cylinder, and the piston is fixedly connected to the movable rod, and a fixed frame is fixedly installed on the end of the movable rod away from the piston.

[0014] Preferably, a telescopic spring is sleeved on the outer side of the movable rod, and one end of the telescopic spring is fixedly connected to the fixed sleeve, and the other end of the telescopic spring is fixedly connected to the fixed frame.

[0015] Preferably, a positioning rod is slidably connected to one side of the inner side of the fixed sleeve, and a plurality of positioning grooves are provided on one side of the movable rod, and the positioning rod is engaged with the positioning grooves.

[0016] Preferably, a return spring is sleeved on the outer side of the positioning rod, and one end of the return spring is fixedly connected to the fixing sleeve, and a fixing block is fixedly installed on the other end of the return spring, and the fixing block is fixedly connected to the positioning rod.

[0017] Preferably, a sliding rod is fixedly installed on one side of the fixed block, and a moving block is slidably connected to the inside side of the fixed frame. The sliding rod and the moving block are slidably connected. Limiting blocks are symmetrically installed on one side of the moving block, and a connecting rod is hinged to the side of the moving block away from the sliding rod. A movable plate is hinged to the end of the connecting rod away from the moving block.

[0018] Preferably, a guide rod is fixedly installed on the other side of the interior of the fixed frame, and the movable plate is slidably connected to the guide rod. A push rod is fixedly installed on one side of the movable plate, and the push rod is slidably connected to the fixed frame. A handle is fixedly installed on the end of the push rod away from the movable plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This anti-reverse exhaust air intake device has symmetrically arranged indicator components on both sides of the oven. If air is escaping from the air inlet, the rotating rod can approach the proximity sensor to trigger an alarm, promptly detecting and alerting to abnormal air intake, allowing for timely troubleshooting, reducing quality risks, and saving production costs. The specific details are as follows:

[0020] 1. Indicator components are symmetrically installed on both sides of the oven. During high-temperature baking, air is drawn in through the air inlet, which is typically fitted with a filter to prevent dust from entering. When installing the indicator components, the mounting plate is aligned with the oven, with the lightweight foam board positioned on one side of the air inlet. This ensures the suction cups are in contact with the oven. Pressing the suction cups adheres them to the oven, initially securing the mounting plate. Then, pulling the fixing frame moves the movable rod, stretching the telescopic spring and causing the piston to move inside the oven cavity. Air on one side of the cavity is expelled through the air outlet. The piston's movement draws air from the suction cups, ensuring they are securely fixed to the oven. During the movement of the movable rod, the positioning groove pushes the positioning rod, stretching the return spring. After the movable rod stops moving, the positioning rod aligns with the corresponding positioning groove. Under the action of the return spring, the positioning rod engages with the positioning groove, preventing the movable rod from resetting. This allows the mounting plate to be fixed on the oven. If air is escaping from the air inlet, the lightweight foam board can be blown to rotate, causing the rotating rod to rotate on the fixed frame. After the rotating rod rotates, it will approach the proximity sensor. At this time, the signal on the proximity sensor is transmitted to the alarm, causing the alarm to sound. This can provide a warning when air is escaping from the air inlet. Through the warning component, if air is escaping from the air inlet, the rotating rod can approach the proximity sensor to trigger an alarm, promptly detecting and alerting to abnormal air intake at the air inlet, identifying potential problems in time, reducing quality risks, and saving production costs.

[0021] 2. To ensure the air intake efficiency, the dust outside the air intake needs to be cleaned regularly. During cleaning, hold the fixed frame and push the handle to move the push rod, which in turn moves the movable plate. The movable plate moves the connecting rod, which in turn moves the moving block. The moving block moves the limiting block into contact with the fixed frame. At the same time, the moving block moves the sliding rod, which in turn moves the fixed block, causing the positioning rod to move and disengage from the positioning groove. This causes the movable rod to lose its limit, allowing it to reset and move again. This allows the suction cup to be inflated, detaching it from the oven, making it easier for staff to remove the indicator component and clean the dust outside the air intake, thus improving the convenience of cleaning.

The other end is fixedly connected to the fixed frame 213, so that the movable rod 209 can automatically return to its original position after moving. A positioning rod 214 is slidably connected to one side of the fixed sleeve 208, and several positioning grooves 215 are provided on one side of the movable rod 209. The positioning rod 214 engages with the positioning grooves 215, allowing the movable rod 209 to be positioned after moving. A return spring 216 is sleeved on the outer side of the positioning rod 214, and one end of the return spring 216 is fixedly connected to the fixed sleeve 208.

A handle 225 is fixedly installed on the end of the push rod 224 away from the movable plate 222, so that the staff can push the movable plate 222 to move.

[0031] Working principle: Before using this type of anti-reverse exhaust intake device, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5As shown, indicator components 2 are symmetrically arranged on both sides of oven 1. When oven 1 is baking at high temperature, air is introduced through air inlet 101. Air inlet 101 is usually equipped with a filter to prevent dust from entering. When installing indicator components 2, mounting plate 201 is attached to oven 1, so that lightweight foam board 204 is on one side of air inlet 101, so that suction cup 207 is attached to oven 1. Press suction cup 207 to adhere to oven 1, and mounting plate 201 is initially fixed. Then, the fixing frame 213 can be pulled to move movable rod 209, so that the telescopic spring 212 can be stretched, which in turn drives piston 210 to move inside cylinder 206. Air on one side of cylinder 206 is discharged through air outlet 211. The movement of piston 210 can suck air from suction cup 207, so that suction cup 207 can be firmly fixed on oven 1. During the movement of movable rod 209, positioning groove 215 can push positioning rod 214 to move and stretch reset spring. After the spring 216 and the movable rod 209 stop moving, the positioning rod 214 is aligned with the corresponding positioning groove 215. Under the action of the return spring 216, the positioning rod 214 is engaged with the positioning groove 215, which can prevent the movable rod 209 from resetting. This allows the mounting plate 201 to be fixed on the oven 1. If the air inlet 101 is emitting air, it can blow the lightweight foam board 204 to rotate, causing the rotating rod 203 to rotate on the fixed frame 202. After the rotating rod 203 rotates, it will approach the proximity sensor 104. At this time, the signal on the proximity sensor 104 is transmitted to the alarm 103, causing the alarm 103 to sound an alarm. This allows the air inlet 101 to emit air and provide a reminder. Through the reminder component 2, if the air inlet 101 emits air, the rotating rod 203 can approach the proximity sensor 104, which can sound an alarm. This allows for timely detection and reminder of abnormal air intake at the air inlet 101, timely investigation of potential hazards, reduction of quality hazards, and saving of production costs.

[0032] To ensure the air intake efficiency of the air inlet 101, the dust on the outside of the air inlet 101 needs to be cleaned regularly. During cleaning, the fixed frame 213 can be held and the handle 225 can be pushed to move the push rod 224, which in turn moves the movable plate 222. The movement of the movable plate 222 causes the connecting rod 221 to rotate. After the connecting rod 221 rotates, it can push the moving block 219 to move. The movement of the moving block 219 makes the limiting block 220 fit with the fixed frame 213. At the same time, the movement of the moving block 219 can also push the sliding rod 218. The sliding rod 218 moves, which in turn moves the fixed block 217, causing the positioning rod 214 to move and disengage from the positioning groove 215. This causes the movable rod 209 to lose its limit, allowing it to reset and move further. This allows the suction cup 207 to be inflated, disengaging it from the oven 1. This makes it easier for staff to remove the indicator component 2 and clean the dust outside the air inlet 101, improving the ease of cleaning.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
