Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher manufacturing technology, and in particular to a fire extinguisher anti-corrosion inner plastic molding machine. Background Technology

[0002] Fire extinguishers are common fire-fighting equipment. There are many types of fire extinguishers, including those that use various chemical agents as extinguishing agents. However, these chemical agents are corrosive to the fire extinguisher cylinder. Therefore, before filling with the extinguishing agent, the inner wall of the fire extinguisher cylinder needs to be treated with anti-corrosion measures. The process of treating the inner wall of the fire extinguisher cylinder with anti-corrosion measures is called "inner plastic treatment".

[0003] A search revealed that Chinese patent application CN222329049U discloses a fire extinguisher anti-corrosion inner plasticizing machine, which mainly adapts to fire extinguishers of different sizes for inner plasticizing by adjusting the size of the installation area.

[0004] Compared with existing technologies in related fields, it can be seen that the nozzle angle of existing devices is fixed. When dealing with tanks of different sizes, the nozzles need to be changed frequently, which is not only cumbersome to operate, but also reduces production efficiency and increases costs.

Detailed Implementation

[0026] like Figures 1-6 As shown, a fire extinguisher anti-corrosion inner plastic coating machine includes a base 1 and a placement platform 2. A lifting unit and a reciprocating unit are fixedly installed on the base 1. A sleeve 9 is fixedly installed on the lifting unit. A spraying unit, a conveying unit, and a measuring unit are fixedly installed at the lower end of the sleeve 9. The placement platform 2 is fixedly installed on the reciprocating unit. A limit unit is fixedly installed on the placement platform 2. The conveying unit is connected to an external conveying device. The fire extinguisher tank to be processed is placed on the placement platform 2 and clamped and fixed by the limit unit. The reciprocating unit drives the placement platform 2 to rotate, and the placement platform 2 rotates the tank to the bottom of the spraying unit. The lifting unit drives the spraying unit, conveying unit, and measuring unit to move through the sleeve 9, so that the spraying unit, conveying unit, and measuring unit enter the tank. The measuring unit detects the size of the tank. The external conveying device delivers the anti-corrosion coating to the spraying unit through the conveying unit. The spraying unit sprays the anti-corrosion coating onto the inner wall of the tank, completing the anti-corrosion treatment of the tank.

[0027] like Figures 2-5 As shown, the spraying unit includes a first motor 301, a hydraulic lifting mechanism 305, and a nozzle 304. Both the first motor 301 and the hydraulic lifting mechanism 305 are fixedly installed at the lower end of the sleeve 9. A mounting base 302 is fixedly installed on the output shaft of the first motor 301. The mounting base 302 is slidably connected to the lower end of the sleeve 9. Support rods 303 are rotatably arranged on the mounting base 302. A transmission rod 308 is rotatably installed on the support rod 303. A slip ring 307 is fixedly installed on the transmission rod 308. A guide ring 306 is slidably installed on the slip ring 307. The guide ring 306 is fixedly connected to the telescopic end of the hydraulic lifting mechanism 305. The nozzle 304 is fixedly installed at the lower end of the support rod 303 and is connected to the material conveying unit. After the sleeve 9 is driven into the tank by the first motor 301 and the mounting base 302, the guide ring 306 is moved up and down according to the size of the tank by the hydraulic lifting mechanism 305. The slip ring 307 moves up and down. During this movement, the slip ring 307 pushes one end of the support rod 303 via the transmission rod 308. The other end of the support rod 303 drives the nozzle 304 to move in the opposite direction, thereby automatically adjusting the spraying direction of the nozzle 304. This facilitates the processing of cans of different sizes, eliminates the need for frequent nozzle replacements, improves production efficiency, reduces costs, and ensures that the nozzle 304 sprays the can at a suitable angle, guaranteeing the quality of the anti-corrosion coating. After the nozzle 304 is adjusted, the material conveying unit delivers the anti-corrosion coating into the nozzle 304, which then sprays it out, completing the anti-corrosion processing of the can. The first motor 301 drives the nozzle 304 to rotate via the mounting base 302 and the support rod 303, causing the nozzle 304 to rotate and spray the can, ensuring the uniformity and quality of the coating.

[0028] like Figure 1 , Figure 6 As shown, the limiting unit includes a second motor 401 and a bidirectional screw 402. There are two second motors 401, both of which are fixedly mounted on the placement platform 2. The bidirectional screw 402 is rotatably mounted on the placement platform 2. The output shafts of the two second motors 401 are respectively fixedly connected to the corresponding bidirectional screws 402. The two ends of the bidirectional screw 402 have opposite thread directions. The two ends of the bidirectional screw 402 are fitted with limiting frames 403 through threaded engagement. The can to be processed is placed on the placement platform 2, so that the can is positioned between the two limiting frames 403. The second motor 401 drives the bidirectional screw 402 to rotate, and the bidirectional screw 402 drives the two limiting frames 403 to move and adjust their positions. The two limiting frames 403 can clamp and fix cans of different sizes, improving the stability of the can during processing.

[0029] like Figure 6 As shown, the reciprocating unit includes a mounting cavity 501 and a third motor 502. The mounting cavity 501 is located inside the base 1, and the third motor 502 is fixedly installed inside the mounting cavity 501. The output shaft of the third motor 502 is rotatably connected to the base 1, and the output shaft of the third motor 502 is fixedly connected to the placement platform 2. The third motor 502 drives the placement platform 2 to reciprocate and rotate, thereby simultaneously loading and unloading the processed tanks, reducing waiting time and improving production efficiency.

[0030] like Figure 1 , Figure 6 As shown, the lifting unit includes a bracket 601, which is fixedly mounted on the base 1. A fourth motor 602 is fixedly mounted on the bracket 601, and a lead screw 603 is rotatably mounted on the bracket 601. The lead screw 603 is fixedly connected to the output shaft of the fourth motor 602, and a movable frame 604 is threadedly connected to the lead screw 603. The movable frame 604 is slidably connected to the bracket 601 and is fixedly connected to the sleeve 9. According to the size and height of the tank, the fourth motor 602 drives the lead screw 603 to rotate, which in turn drives the movable frame 604 to move. The movable frame 604 then drives the sleeve 9 to move up and down, thereby adjusting the height of the spraying unit. This allows for the handling of different height positions for tanks of different sizes.

[0031] like Figures 3-5As shown, the material conveying unit includes a mounting box 704, a material conveying ring 705, and a guide tube 706. The mounting box 704 and the material conveying ring 705 are fixedly mounted on the sleeve 9. The mounting boxes 704 are arranged in an orderly manner, and a movable part 702 is slidably mounted on the mounting box 704. The material conveying ring 705 is divided into an upper stabilizing part and a lower movable part, which are rotatably connected. The upper stabilizing part of the material conveying ring 705 is fixedly connected to the sleeve 9. The guide tube 706 passes through the mounting box 704 and is fixedly connected to the mounting box 704. The two ends of the guide tube 706 are respectively connected to... The nozzle 304 and the feeding ring 705 are connected. One end of the guide tube 706 is fixedly connected to the nozzle 304, and the other end of the guide tube 706 is fixedly connected to the lower movable part of the feeding ring 705, so that the guide tube 706 can always be connected to the feeding ring 705. A roller mechanism 701 is fixedly installed at the end of the movable part 702. The movable part 702 is slidably connected to the guide tube 706. A spring 703 is sleeved on the movable part 702. The two ends of the spring 703 are connected to the mounting box 704 and the roller mechanism 701. The upper stabilizing part of the feeding ring 705 is fixedly connected to the external feeding part. The device includes a flexible guide tube 706 and a roller mechanism 701 that slidably connects a support rod 303 and a mounting base 302. During processing, an external material conveying device delivers the anti-corrosion coating to the guide tube 706 via a material conveying ring 705, and then to the nozzle 304, completing the delivery of the anti-corrosion coating. Simultaneously, under the elastic force of a spring 703, the spring 703 pushes the roller mechanism 701 to adhere to the support rod 303. The support rod 303, through the roller mechanism 701, drives the movable part 702 to adhere to the guide tube 706, thus completing the processing. During the process, when the tilt angle of the support rod 303 is adjusted, the support rod 303 pushes the roller mechanism 701 and squeezes the spring 703. The roller mechanism 701 drives the movable part 702 to move, so that the movable part 702 squeezes the guide pipe 706, reducing the inner diameter of the guide pipe 706. By reducing the pipe diameter, the speed of the anti-corrosion coating when passing through is increased. Thus, when processing tanks with different pipe diameters, the speed of coating spraying is automatically compensated and adjusted, so as to uniformly spray the tank and ensure the speed and quality of anti-corrosion coating spraying.

[0032] like Figure 2 , Figure 3 As shown, the measuring unit includes a distance sensor 8, which is fixedly arranged at the lower end of the sleeve 9. During the anti-corrosion processing of the inner wall of the tank, the distance sensor 8 detects the inner wall dimensions of the tank, thereby improving the processing of the tank.

[0033] like Figures 3-5As shown, a material collection mechanism 10 is fixedly installed at the lower end of the sleeve 9. The material collection mechanism 10 is fixedly connected to the first motor 301. The material collection mechanism 10 is slidably connected to the mounting base 302. Return holes 11 are arranged inside the mounting base 302. The return holes 11 are connected to the material collection mechanism 10. The material collection mechanism 10 is slidably connected to the mounting base 302. When the mounting base 302 rotates, it will not affect the connection between the return holes 11 and the material collection mechanism 10. The material collection mechanism 10 is connected to an external residual material recovery device. During the anti-corrosion treatment of the inside of the tank, the external residual material recovery device extracts the excess anti-corrosion coating floating in the return holes 11 through the material collection mechanism 10, effectively reducing the waste of anti-corrosion coating and environmental pollution, and improving the utilization rate of anti-corrosion coating.

[0034] Working principle: such as Figure 1 , Figure 6 As shown, the can to be processed is placed on the placement platform 2, and the can is positioned between the two limiting frames 403. The second motor 401 drives the bidirectional screw 402 to rotate, and the bidirectional screw 402 drives the two limiting frames 403 to move, so that the two limiting frames 403 clamp and fix the can.

[0035] like Figures 2-6 As shown, the third motor 502 drives the placement platform 2 to rotate, and the placement platform 2 drives the tank to rotate through two limit brackets 403, so that the tank moves to the direct under the mounting base 302.

[0036] like Figures 1-3 , Figure 6 As shown, based on the dimensions and height of the tank, the fourth motor 602 drives the lead screw 603 to rotate, and the lead screw 603 drives the movable frame 604 to move. The movable frame 604 drives the sleeve 9 to move up and down, so that the sleeve 9 drives the mounting base 302 into the tank through the first motor 301. The inner wall dimensions of the tank are detected by the distance sensor 8.

[0037] like Figures 2-5 As shown, according to the size of the tank, the guide ring 306 is driven to move up and down by the hydraulic lifting mechanism 305. The guide ring 306 drives the slip ring 307 to move up and down. During the movement of the slip ring 307, the slip ring 307 pushes one end of the support rod 303 through the transmission rod 308. The other end of the support rod 303 drives the nozzle 304 to move in the opposite direction, thereby adjusting the tilt angle of the nozzle 304.

[0038] like Figures 3-5As shown, when the tilt angle of the support rod 303 is adjusted, the support rod 303 pushes the roller mechanism 701 and squeezes the spring 703. The roller mechanism 701 drives the movable part 702 to move, so that the movable part 702 squeezes the guide pipe 706, reduces the inner diameter of the guide pipe 706, and adjusts the speed of conveying the anti-corrosion coating in the guide pipe 706. At the same time, after the nozzle 304 is adjusted, the external conveying device conveys the anti-corrosion coating into the guide pipe 706 through the conveying ring 705, and then conveys it into the nozzle 304 through the guide pipe 706. The coating is then sprayed out through the nozzle 304 to spray the anti-corrosion coating onto the inner wall of the tank.

[0039] like Figures 1-6 As shown, the first motor 301 drives the nozzle 304 to rotate through the mounting base 302 and the support rod 303, so that the nozzle 304 rotates and sprays the can body. The fourth motor 602 drives the lead screw 603 to rotate in the opposite direction, and the lead screw 603 drives the movable frame 604 to move in the opposite direction, adjusting the spraying height of the nozzle 304 in the can body, thereby spraying the can body at different heights.

[0040] At the same time, such as Figures 3-5 As shown, after the spraying is completed, the external residual material recovery device extracts the excess anti-corrosion coating floating in the return hole 11 through the collection mechanism 10, thus completing the recovery of the excess coating.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
