Description

Technical Field

[0001] This utility model relates to the technical field of fire extinguisher processing equipment, specifically to an automatic fire extinguisher inflation processing production line. Background Technology

[0002] As a commonly used fire-fighting equipment, the stability of fire extinguishing performance of fire extinguishers directly affects the effectiveness of fire suppression. During the production process of fire extinguishers, a certain amount of air or nitrogen needs to be filled into the canister before it leaves the factory. By establishing a stable internal pressure, it is ensured that the extinguishing medium, such as dry powder, can be sprayed quickly and evenly during use, thereby achieving long-term stable fire extinguishing function.

[0003] Currently, the industry generally uses manual methods to complete the inflation of fire extinguisher canisters. The specific operation process is as follows: Before inflation, the fire extinguisher canister needs to undergo two key pre-treatment processes: First, vibration processing. Since the dry powder inside the canister is prone to sedimentation and compaction during storage and transportation, vibration is needed to loosen and fluff the dry powder to avoid the accumulation of dry powder during inflation, which would affect pressure establishment and spray effect. Second, canister positioning. It is necessary to ensure that the valve interface of the canister is accurately aligned with the inflation clamp, otherwise it will lead to inflation leakage or docking failure.

[0004] However, in existing technologies, vibration processing, bottle positioning, and inflation are independent processes that require multiple steps and multiple machines to complete, lacking a coherent workflow. Furthermore, there is no integrated production line on the market specifically designed for fire extinguisher inflation, which cannot simultaneously achieve integrated operation of vibration pretreatment, precise bottle positioning, and automated inflation. This results in cumbersome process connections, further reducing production efficiency and increasing the probability of problems such as positioning deviations and secondary compaction of dry powder caused by inter-process transfer.

[0048] like Figure 1-11The automatic fire extinguisher inflation production line shown includes a frame, a conveyor belt 1 mounted on the frame, a pushing component 2 positioned next to the input end of the conveyor belt 1, a tilting component 3 positioned opposite the pushing component 2, a powder loosening component 5 positioned above the tilting component 3, a lifting handle pressing component 6 positioned next to the pushing component 2, a lifting handle positioning component 7 positioned next to the end of the lifting handle pressing component 6 away from the pushing component 2, the lifting handle positioning component 7 positioned at both ends of the conveyor belt 1, and an inflation component positioned next to the end of the lifting handle positioning component 7 away from the lifting handle pressing component 6, positioned above the conveyor belt 1. It should be noted that the tilting component 3 is designed to quickly clamp fire extinguishers of different sizes for subsequent tilting and powder loosening processing. The tilting component 3, powder loosening component 5, lifting handle positioning component 7, and inflation component are suitable for processing two fire extinguishers simultaneously, ensuring processing efficiency. A fire extinguisher positioning sensor is positioned opposite the tilting component 3 to detect whether the fire extinguisher has reached the designated position, so that the conveyor belt 1 stops working and the tilting component 3 starts working.

[0049] Specifically, the pushing assembly 2 includes a fire extinguisher placement plate 201, which is positioned beside the conveyor belt 1. A cylinder mounting base is located at the end of the fire extinguisher placement plate 201 furthest from the conveyor belt 1. A fire extinguisher pushing cylinder 202 is mounted on the cylinder mounting base. A pushing plate 203 is located at the output end of the fire extinguisher pushing cylinder 202. There are two pushing plates 203, one on the left and one on the right. A fire extinguisher auxiliary positioning sensor 204 is positioned above each pushing plate 203, and the auxiliary positioning sensor 204 is located at the top of the cylinder mounting base. It should be noted that the fire extinguisher placement plate 201 can be replaced by a conveyor belt containing the fire extinguishers to be processed. This, combined with the fire extinguisher pushing cylinder 202 and the conveyor belt 1, enables automated conveying. Simultaneously, it works with the fire extinguisher auxiliary positioning sensor 204 to achieve rapid positioning of the fire extinguishers, and with the fire extinguisher pushing cylinder 202 and the pushing plate 203, facilitates transfer, thus aiding subsequent processing operations.

[0050] Specifically, the flipping component 3 includes two clamping block pushing cylinders 301, which are disposed on the end of the mounting plate 3001 away from the conveyor belt 1. A base plate 4 is disposed at the bottom of the mounting plate 3001, and the base plate 4 is mounted on a sliding adjustment component, which is mounted on a frame. The output ends of the two clamping block pushing cylinders 301 are positioned opposite each other, and each output end of the two clamping block pushing cylinders 301 is respectively provided with an active rack 302. The active racks 302 are slidably disposed within limiting rectangular holes, which are respectively opened at the left and right ends of the mounting plate 3001. Two gears 302 and 304 are respectively engaged with one end of gear 303. Gear 303 is rotatably mounted on mounting plate 3001 via a rotating shaft. The other ends of the two gears 303 are respectively connected to driven rack 304. Drive rack 302 and driven rack 304 are respectively connected to clamping block mounting base 305. The upper and lower ends of clamping block mounting base 305 are respectively connected to slide rails via slide blocks. Two slide rails are respectively set on the upper and lower ends of mounting plate 3001. Clamping blocks 306 are respectively set on the upper and lower ends of clamping block mounting base 305. One end of mounting plate 3001 is connected to the output end of flipping drive assembly. Flipping drive assembly is set on base plate 4. It should be noted that the clamping block push cylinder 301 works to drive drive rack 302 to move within the limiting rectangular hole. In conjunction with the rotation of gear 303, driven rack 304 moves, thereby moving clamping block mounting base 305, achieving the effect of adjusting the working position of clamping block 306, which is convenient for clamping fire extinguishers of different specifications and models, and facilitates subsequent processing.

[0051] There are four clamping block mounting seats 305 in total, two in a group. The two groups are symmetrically arranged with the center line of the mounting plate 3001 as the center of symmetry. The two clamping block mounting seats 305 in each group move away from or towards each other through the cooperation of the sliding seat and the sliding rail, so as to cooperate with the clamping block 306 to clamp and release the fire extinguisher.

[0052] The clamping blocks 306 are arranged in a V-shape with anti-slip pads on the contact surface with the fire extinguisher. The V-shape of the clamping blocks 306 and the anti-slip pads facilitate clamping and fixing the fire extinguisher, ensuring its stability when the powder is released after it is turned over, and preventing the fire extinguisher from falling off during the manufacturing process.

[0053] Specifically, the flip drive assembly includes a drive motor 310, the output end of which is connected to the input end of a reducer 309. The reducer 309 is connected to the base plate 4 via a mounting bracket. A drive gear 308 is provided at the output end of the reducer 309. A driven gear 307 is meshed below the drive gear 308. A rotating shaft is provided on the driven gear 307 and connected to one end of a mounting plate 3001. The left and right ends of the mounting plate 3001 are respectively connected to bearing seats 311 via rotating shafts. The bearing seats 311 are provided on a shock absorber seat 312, which is provided on the base plate 4. A rotation positioning sensor is provided at the end of the mounting plate 3001 away from the driven gear 307. It should be noted that the setting of the rotation positioning sensor will cause the drive motor 310 to work in conjunction with the active gear 308 and the driven gear 307 to precisely rotate the mounting plate 3001 by 180 degrees to achieve the required rotation effect of the fire extinguisher, so that the fire extinguisher is rotated to be directly below the powder loosening component 5. At this time, the bottom of the fire extinguisher is facing upward, which is convenient for subsequent powder loosening processing. At the same time, it is convenient for the drive motor 310 to work after the powder loosening is completed to drive the mounting plate 3001 to rotate and reset.

[0054] Specifically, the sliding adjustment assembly includes a first servo motor 313, which is mounted on the frame. An auxiliary lead screw 314 is mounted on the output end of the first servo motor 313. A transmission block 315 is threadedly connected to the auxiliary lead screw 314. The top of the transmission block 315 is connected to the base plate 4. The left and right ends of the bottom of the base plate 4 are connected to guide rails via sliders, and the guide rails are mounted on the frame. It should be noted that the operation of the first servo motor 313 drives the auxiliary lead screw 314 to rotate, thereby causing the transmission block 315 to move the base plate 4 on the guide rails, thus moving the tilting assembly 3 to the desired working position.

[0055] Specifically, the powder loosening component includes a U-shaped mounting bracket mounted on the base plate 4. A lifting cylinder 501 is mounted at the top of the U-shaped mounting bracket, and a connecting frame 502 is mounted at the output end of the lifting cylinder 501. Shock-absorbing rods 503 are mounted on the left and right ends of the connecting frame 502, respectively, and are connected to a pressure plate 504. Vibration motors 505 are mounted on the pressure plate 504. It should be noted that when the lifting cylinder 501 operates, it lowers the pressure plate 504 to the bottom of the fire extinguisher. The vibration motors 505 then vibrate the pressure plate 504 and the fire extinguisher to loosen the powder. After processing, the lifting cylinder 501 returns to its original position, and the pressure plate 504 moves away from the fire extinguisher.

[0056] Specifically, the lifting handle pressing assembly 6 includes a column 601 mounted on the frame. A pressing cylinder 602 is mounted at the top of the column 601, and a pressing plate 603 is mounted at the output end of the pressing cylinder 602. It should be noted that the column 601 is also equipped with a sensor to facilitate sensing the arrival of the fire extinguisher. This sensor activates the pressing cylinder 602, pressing down and resetting the lifting handle of the fire extinguisher after the powder has been loosened, facilitating subsequent inflation and ensuring proper inflation.

[0057] Specifically, the lifting handle positioning component 7 includes a mounting base 701, which is located beside one end of the conveyor belt 1. An upper slide plate 702 is slidably mounted on the mounting base 701. The upper slide plate 702 is connected to a screw adjusting handwheel 703, which is mounted on the mounting base 701. Guide rails are respectively provided on the left and right ends of the upper slide plate 702 to cooperate with sliders. A motor mounting base 704 is mounted on the slider. One end of the motor mounting base 704 is connected to the output end of an adjusting cylinder 705. The adjusting cylinder 705 is mounted on the upper slide plate 702, and a second servo motor 706 is mounted on the motor mounting base 704. The output end of the second servo motor 706 is equipped with a pulley, which is connected to the driven wheel via a belt. The driven wheel is located at the bottom of the drive roller 707. The drive roller 707 is rotatably mounted on the motor mounting base 704 via a mounting bracket. An auxiliary adjusting cylinder 708 is set on the opposite side of the mounting base 701. The auxiliary adjusting cylinder 708 is mounted on the frame. An auxiliary mounting bracket is set at the output end of the auxiliary adjusting cylinder 708. Driven rollers 709 are respectively set on the left and right ends of the auxiliary mounting bracket. A lifting handle positioning sensor 710 is set above the driven rollers 709. The lifting handle positioning sensor 710 is mounted on the frame via a mounting rod. It should be noted that the setting of the screw adjusting handwheel 703 can adjust the distance between the driven roller 709 and the driving roller 707 according to the fire extinguisher specifications, so as to be suitable for the use of different specifications and models of fire extinguishers. At the same time, the setting of the adjusting cylinder 705 will cause the driving roller 707 to move and fit against one end of the fire extinguisher after the fire extinguisher is in position. Simultaneously, the auxiliary adjusting cylinder 708 will drive the driven roller 709 to move and fit against the other end of the fire extinguisher. At this time, the fire extinguisher is located between the driving roller 707 and the driven roller 709.

[0058] The second servo motor 706 works in conjunction with the pulley, belt, and driven wheel to make the active roller 707 drive the fire extinguisher to rotate until the lifting handle positioning sensor 710 senses that the lifting handle is in place, at which point the second servo motor 706 stops working, thus achieving the desired lifting handle positioning effect.

[0059] Two driven rollers 709 are grouped together, and the driving roller 707 is set between the two driven rollers 709 on opposite sides, which facilitates the positioning and clamping of the fire extinguisher, and works in conjunction with the second servo motor 706 to achieve effective rotation of the fire extinguisher;

[0060] Above the second servo motor 706, there is also an air blowing pipe mounting bracket. The air blowing pipe mounting bracket is set on the frame, and the air blowing pipe is set on the air blowing pipe mounting bracket to connect to the gas station. The air blowing pipe is aligned with the pressure gauge of the fire extinguisher so that after the fire extinguisher pressure handle is positioned, it is easy to blow air to clean the outer surface of the pressure gauge, which is convenient for the subsequent work of the inflation component.

[0061] Specifically, the inflation assembly includes a mounting frame, with fire extinguisher positioning and clamping components 8 installed at both the front and rear ends of the mounting frame, an inflation lifting drive assembly 10 installed at the top of the mounting frame, and a pressure gauge detection vision assembly 9 installed at the bottom of the inflation lifting drive assembly 10. It should be noted that the working heights of both the inflation lifting drive assembly 10 and the pressure gauge detection vision assembly 9 can be adjusted according to the height of the fire extinguisher, with the pressure gauge detection vision assembly 9 aligned with the fire extinguisher's pressure gauge.

[0062] Specifically, the fire extinguisher positioning and clamping assembly 8 includes a clamping drive cylinder 801, which is mounted on the mounting frame. Roller mounting brackets 802 are respectively mounted on the output end of the clamping drive cylinder 801, and rollers 803 are respectively mounted at the four corners of the opposite ends of the front and rear roller mounting brackets 802. It should be noted that the fire extinguisher will rotate slightly during the limiting phase before inflation. The combination of the roller mounting brackets 802 and the rollers 803 ensures that the fire extinguisher can rotate during the limiting phase without damaging the paint on the outer wall of the fire extinguisher.

[0063] Specifically, the inflatable lifting drive assembly 10 includes a lifting slide 1001, which is slidably mounted on the mounting frame at its four corners. One end of the lifting slide 1001 is threadedly connected to a lead screw 1002, which is rotatably connected to the mounting frame via bearings. An auxiliary driven gear 1003 is mounted at the top of the lead screw 1002, which is connected to an auxiliary driving gear 1004 via a chain. The auxiliary driving gear 1004 is located at the output end of a lifting drive motor 1005, which is mounted on the mounting frame. A lifting drive cylinder 1006 is mounted on the lifting slide 1001, and a transmission plate 1007 is mounted at the output end of the lifting drive cylinder 1006. The four corners of the transmission plate 1007 are connected to the lifting slide 1001 via guide posts. The bottom end of 007 is connected to the auxiliary lower mounting plate 1009 via a buffer rod 1008. One end of the auxiliary lower mounting plate 1009 is equipped with an auxiliary lifting handle pressing cylinder 1015, and the output end of the auxiliary lifting handle pressing cylinder 1015 is equipped with a pressure block 1016. The other end of the auxiliary lower mounting plate 1009 is equipped with an inflation head adjusting cylinder 1012, and the output end of the inflation head adjusting cylinder 1012 is equipped with an inflation head 1013. The inflation head 1013 is connected to an air station 1014, which is mounted on the mounting frame. Next to the inflation head 1013 is a lifting handle clamping plate 1010, which is located at the bottom of the auxiliary lower mounting plate 1009. Opposite to the lifting handle clamping plate 1010 is a lifting handle positioning cylinder 1011, which is mounted on the auxiliary lower mounting plate 1009. It should be noted that the bottom end of the pressure handle plate 1010 is provided with a pressure gauge opening positioning groove and a positioning rod opening slot. The output end of the pressure handle positioning cylinder 1011 is provided with a positioning rod located in the positioning rod opening slot. When the pressure handle plate 1010 is lowered to the required working position, the pressure gauge rod is located in the pressure gauge opening positioning groove. The pressure handle positioning cylinder 1011 extends the positioning rod and inserts it into the positioning rod opening slot. At this time, the fire extinguisher is fixedly positioned on the pressure handle plate 1010, which facilitates subsequent inflation.

[0064] The auxiliary lifting handle lowering cylinder 1015 works to drive the pressure block 1016 to descend and press down the lifting handle to open the fire extinguisher for easy inflation.

[0065] The operation of the inflation head adjusting cylinder 1012 drives the inflation head 1013 to connect with the fire extinguisher, ensuring that the inflation head 1013 works with the gas station 1014 to inflate the fire extinguisher;

[0066] When it is necessary to adjust the working position of the lifting slide 1001 to suit fire extinguishers of different heights, the lifting drive motor 1005 works in conjunction with the auxiliary drive gear 1004, chain, and auxiliary driven gear 1003 to drive the lead screw 1002 to rotate, thereby raising and lowering the lifting slide 1001 from the mounting frame to the required working position, thus achieving the effect of adjusting the inflation position.

[0067] Specifically, the pressure gauge detection vision component 9 includes a vision sensor mounting bracket 901, which is located at one end of the lifting slide 1001. A ring light source 902 is positioned at the bottom of the vision sensor mounting bracket 901. A vision sensor 903 is positioned at the end of the ring light source 902 furthest from the fire extinguisher, and is mounted on the vision sensor mounting bracket 901, located on the center line of the ring light source 902. It should be noted that when the vision sensor 903 is working, it senses the pressure gauge pointer moving to a safe area, causing the pressure block 1016 to rise and reset, moving away from the pressure handle, thus closing the fire extinguisher. Subsequently, the inflation head 1013 stops inflating, and the inflation head adjusting cylinder 1012 operates, causing the inflation head 1013 to reset, achieving a precise and automatic inflation effect.

[0068] The working principle of this specific implementation is as follows: First, the fire extinguisher to be processed is placed on the fire extinguisher placement plate 201. The fire extinguisher auxiliary positioning sensor 204 senses that the fire extinguisher is in place. The fire extinguisher pushing cylinder 202 works to move the pushing plate 203 and push the fire extinguisher to the conveyor belt 1. The fire extinguisher is then transported to the next processing station via the conveyor belt 1.

[0069] When the fire extinguisher positioning sensor detects that the fire extinguisher is in place, the conveyor belt 1 stops conveying. At this time, the servo motor 313 works to drive the auxiliary lead screw 314 to rotate, thereby causing the clamping block 306 to move to the left and right ends of the fire extinguisher. The clamping block pushes the cylinder 301 to work, which drives the active rack 302 to move in the limiting rectangular hole. In conjunction with the rotation of the gear 303, the driven rack 304 moves, which in turn moves the clamping block mounting seat 305, thereby adjusting the clamping block 306 to clamp the fire extinguisher.

[0070] After the fire extinguisher is clamped, the drive motor 310 works in conjunction with the drive gear 308 and the driven gear 307 to make the mounting plate 3001 rotate precisely 180 degrees, so that the bottom of the fire extinguisher is flipped upwards and directly under the pressure plate 504.

[0071] When the lifting cylinder 501 operates, it drives the pressure plate 504 to descend and press down to the bottom of the fire extinguisher. The vibration motor 505 operates to vibrate and loosen the powder on the pressure plate 504 and the fire extinguisher. After the processing is completed, the lifting cylinder 501 operates to reset and the pressure plate 504 moves away from the fire extinguisher.

[0072] The drive motor 310 works to rotate and reset the mounting plate 3001, and the fire extinguisher returns to the top of the conveyor belt 1. The cylinder 301 is pushed by the clamping block to work the clamping block 306 to move away from each other and release the fire extinguisher. The first servo motor 313 works and resets to move the clamping block 306 away from the conveyor belt 1, so that the conveyor belt 1 can continue to work to transport the processed fire extinguisher to the bottom pressure plate 603, and the unprocessed fire extinguisher is transported to the waiting processing station.

[0073] When the sensor on the column 601 detects that the fire extinguisher is in place, it activates the pressing cylinder 602 to press the fire extinguisher, which has finished flipping and loosening the powder, back down to facilitate subsequent inflation and positioning, and ensure that inflation proceeds normally.

[0074] The conveyor belt 1 operates to transport the fire extinguisher between the active roller 707 and the driven roller 709. The adjusting cylinder 705 operates to move the active roller 707 to fit against one end of the fire extinguisher. At the same time, the auxiliary adjusting cylinder 708 operates to drive the driven roller 709 to move to fit against the other end of the fire extinguisher. At this time, the fire extinguisher is located between the active roller 707 and the driven roller 709.

[0075] The second servo motor 706 works in conjunction with the pulley, belt, and driven wheel to drive the active roller 707 to rotate the fire extinguisher until the lifting handle positioning sensor 710 senses that the lifting handle is in place. Then the second servo motor 706 stops working, allowing the fire extinguisher to rotate to the required positioning position.

[0076] Conveyor belt 1 transports the fire extinguisher, which has been rotated and positioned, to the area below the auxiliary lower mounting plate 1009. Lifting drive cylinder 1006 operates to drive the auxiliary lower mounting plate 1009 to descend, thereby causing the pressure handle plate 1010 to descend to the required working position. The pressure gauge rod is located in the pressure gauge opening positioning slot. The pressure handle positioning cylinder 1011 operates to extend the positioning rod. The positioning rod passes through the bottom of the pressure handle and is inserted into the positioning rod opening slot. At this time, the fire extinguisher pressure handle is fixed and limited on the auxiliary lower mounting plate 1009. At this time, the fire extinguisher nozzle and the inflation head 1013 are on the same center line.

[0077] When the inflation head adjusting cylinder 1012 operates, it drives the inflation head 1013 to connect with the fire extinguisher, ensuring that the inflation head 1013 works in conjunction with the gas station 1014 to inflate the fire extinguisher. At this time, the ball valve of the inflation head 1013 opens. Subsequently, the auxiliary pressure handle pressing cylinder 1015 operates, driving the pressure block 1016 to descend and press down the pressure handle, thus opening the fire extinguisher for inflation. During the inflation process, the ring light source 902 is aligned with the pressure gauge, and the vision sensor 903 operates to sense and detect that the pressure gauge pointer has moved to a safe area. The auxiliary pressure handle pressing cylinder 1015 operates, driving the pressure block 1016 to rise and reset, moving away from the pressure handle, thereby closing the fire extinguisher. Subsequently, the inflation head 1013 closes and stops air intake. The inflation head adjusting cylinder 1012 operates, driving the inflation head 1013 to reset and move away from the fire extinguisher. The pressure handle positioning cylinder 1011 operates, causing the positioning rod to reset and move away from the pressure handle locking plate 1010.

[0078] The lifting drive cylinder 1006 drives the auxiliary mounting plate 1009 to rise and reset away from the fire extinguisher. Once the fire extinguisher is fully charged, it can be transported to the next processing station via the conveyor belt 1.
