[0002] The production of fire extinguisher cylinders usually involves processes such as bottle body rolling, longitudinal seam welding, upper and lower head welding, and bottle valve seat welding. In order to ensure product quality and subsequent use, the fire extinguisher cylinders must generally be tested for air tightness to detect whether the air tightness of the fire extinguisher cylinders is qualified. When testing the air tightness of fire extinguisher cylinders, a corresponding continuous loading device is required to continuously convey multiple fire extinguisher cylinders forward in sequence, making it convenient for the corresponding clamping and conveying mechanism to clamp and convey multiple cylinders at the same time.

[0007] As a further solution of the present invention: a rectangular through groove is opened on the outer wall of the bottom of the fixing block, and the third cylinder is slidably connected to the inner wall of the rectangular through groove.

[0008] As a further solution of the present invention: the movable length of the third cylinder on the inner wall of the rectangular through groove is equal to the interval length between the two arc grooves.

[0011] As a further solution of the present invention: a group of second feeding frames are fixed to the outer walls of both sides of the first feeding frame, and a shielding plate is fixed to the outer wall of the second connecting rod.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

The outer wall of the testing bracket 1 is provided with a control panel, and the grabbing mechanism 2, the continuous feeding mechanism 3, the clamping and conveying mechanism 4, the air filling and pressure testing mechanism 5, and the discharging mechanism 6 are electrically connected to the control panel respectively;

[0035] The grabbing mechanism 2 includes a first L-shaped plate 21, a cushion block 22, a second L-shaped plate 23, a first three-rod cylinder 24, a swing frame 201, a first connecting rod 25, a mounting plate 28, a first electromagnet 27 and a rotating cylinder 207. The first L-shaped plate 21 is fixed to an outer wall of one side of the detection bracket 1 by screws, the cushion block 22 is fixed to an outer wall of the first L-shaped plate 21, the second L-shaped plate 23 is arranged on the cushion block 22, the first three-rod cylinder 24 is fixed to an outer wall of one side of the second L-shaped plate 23, the rotating cylinder 207 is arranged on the output end of the first three-rod cylinder 24, the swing frame 201 is arranged on the output end of the rotating cylinder 207, the first connecting rod 25 is fixed to the inner wall of the swing frame 201, the mounting plate 28 is fixed to an outer wall of one side of the first connecting rod 25, and the first electromagnet 27 is fixed to the bottom outer wall of the mounting plate 28;

[0036] A set of first cylinders 26 are fixed to the top outer wall of the mounting plate 28, and the output end of the first cylinder 26 passes through the outer wall of one side of the mounting plate 28;

[0037] A push block 29 is fixed to the output end of the first cylinder 26 .

[0038] When the fire extinguisher cylinder 7 is moved from the previous processing step to the side of the grabbing mechanism 2 through the conveyor belt, the first three-rod cylinder 24 on the side of the second L-shaped plate 23 will drive the swing frame 201 to move downward a set distance, so that the first electromagnet 27 at the bottom of the mounting plate 28 moves to the outer wall of the fire extinguisher cylinder 7, and then the control panel controls the first electromagnet 27 to be energized, and the fire extinguisher cylinder 7 is adsorbed and fixed by magnetic force. Then the first three-rod cylinder 24 drives the swing frame 201 to move upward and reset, and at the same time controls the rotating cylinder 207 to drive the swing frame 201 and the mounting plate 28 to rotate ninety degrees as a whole toward the side of the continuous feeding mechanism 3, so that the fire extinguisher cylinder 7 is rotated ninety degrees. At the same time, it follows the mounting plate 28 to move to the top of the continuous feeding mechanism 3, and then the first three-rod cylinder 24 drives the swing frame 201 to move downward by a corresponding distance again, so that the fire extinguisher cylinder 7 after adjusting the direction is placed on the continuous feeding mechanism 3, and then the control panel controls the first electromagnet 27 to cut off the power, and at the same time controls the first cylinder 26 to push the push block 29 to move back and forth downward, pushing the fire extinguisher cylinder 7 completely into the continuous feeding mechanism 3, and then the control panel controls the rotating cylinder 207 and the first three-rod cylinder 24 again to drive the swing frame 201 and the mounting plate 28 to reset, preparing to grab and transport the next fire extinguisher cylinder 7 that is transported by the conveyor belt and needs to be tested for air tightness.

[0039] At the same time, pads 22 of different heights can be fixed between the second L-shaped plate 23 and the first L-shaped plate 21 by screws, and the height between the bottom of the mounting plate 28 and the conveyor belt can be changed, so that the grabbing mechanism can grab and transport fire extinguisher cylinders 7 of different sizes, thereby improving the overall applicability of the grabbing mechanism.

[0040] By setting up a grabbing mechanism 2 that can transport the fire extinguisher cylinder 7 and adjust the direction of the fire extinguisher cylinder 7, the fire extinguisher cylinder 7 processed in the previous process can be continuously and stably grabbed and placed on the continuous feeding mechanism 3, quickly completing the transfer of the fire extinguisher cylinder 7 while improving the sealing detection efficiency of the fire extinguisher cylinder 7.

[0041] like Figure 1 、 Figure 4 and Figure 5 As shown, the continuous feeding mechanism 3 includes a first feeding frame 32, a second cylinder 33, a second feeding frame 35, a fixed block 38, a third cylinder 34 and a movable block 37. The first feeding frame 32 is fixed to the inner wall of the detection bracket 1, the second cylinder 33 and the fixed block 38 are respectively fixed to the bottom inner wall of the first feeding frame 32, the movable block 37 is slidably connected to the outer wall of the fixed block 38, the output shaft of the third cylinder 34 is fixed to the bottom inner wall of the second feeding frame 35, and the output shaft of the second cylinder 33 is fixed to one side outer wall of the movable block 37;

[0042] The outer wall of the bottom of the fixing block 38 is provided with a rectangular through slot, and the third cylinder 34 is slidably connected to the inner wall of the rectangular through slot;

[0043] The third cylinder 34 can move on the inner wall of the rectangular through groove by a length equal to the distance between the two arc-shaped grooves;

[0044] The top outer walls of the first feeding frame 32 and the second feeding frame 35 are respectively provided with a plurality of arc-shaped grooves adapted to the outer walls of the fire extinguisher cylinder 7;

[0045] The spacing between the multiple arc-shaped grooves on the top outer walls of the first feeding frame 32 and the second feeding frame 35 is the same;

[0046] A set of second feeding frames 35 are fixed to the outer walls of both sides of the first feeding frame 32 , and a shielding plate 31 is fixed to the outer wall of the second connecting rod 36 .

[0047] After the fire extinguisher cylinder 7 is placed inside the outermost pair of arc-shaped grooves on the first feed frame 32 through the grabbing mechanism 2, the control panel will then control the third cylinder 34 to push the second feed frame 35 to move upward to a corresponding height as a whole, thereby lifting the fire extinguisher cylinder 7 on the first feed frame 32 to a certain height through the arc groove on the outer wall of the second feed frame 35, so that the fire extinguisher cylinder 7 is lifted up from the arc groove at the top of the first feed frame 32 by the second feed frame 35, and then the control panel controls the second cylinder 33 to push the movable block 37 to move forward as a whole. When the third cylinder 34 moves to the fixed block 38 After reaching one end of the bottom rectangular through groove, the fire extinguisher cylinder 7 on the top of the second feeding frame 35 will move to the top of the next arc groove under the drive of the third cylinder 34, and then the control panel controls the third cylinder 34 to drive the second feeding frame 35 to move downward and reset, thereby transporting the fire extinguisher cylinder 7 in sequence to the next arc groove on the outer wall of the first feeding frame 32, and then the control panel controls the second cylinder 33 to drive the movable block 37 to move backward and reset, and then repeat the above steps, so that the fire extinguisher cylinder 7 placed on the first feeding frame 32 by the grabbing mechanism 2 can be stably arranged and transported forward in sequence;

[0048] When the fire extinguisher cylinder 7 moves to the innermost arc groove under the conveyance of the second feeding frame 35, the clamping and conveying mechanism 4 will grab the multiple fire extinguisher cylinders 7 arranged in sequence on the top of the second feeding frame 35 under the control of the control panel and convey them to the inside of the inflation and pressure testing mechanism 5 for air tightness testing.

[0049] The shielding plate 31 can clamp and limit the two ends of the fire extinguisher cylinder 7 being transported at the top of 32 and the second feeding frame 35, so that multiple fire extinguisher cylinders 7 can still be arranged neatly when being transported forward.

[0050] like Figure 1 and Figure 8-10As shown, the inflation pressure test mechanism 5 includes a testing water pool 58, a fixed frame 51, an eighth cylinder 53, a movable frame 54, a telescopic rod 55, a support plate 505, a seventh cylinder 52, a fifth cylinder 56, an inflation plate 57, a support rod 511, a support sheet 510, a stripper plate 509, a push-pull rod 508 and an air injection pipe 507;

[0052] The plurality of seventh cylinders 52 are respectively fixed to the inner wall of the support plate 505, a group of support rods 511 are fixed to the outer wall of the telescopic rod 55, a support plate 510 is fixed to the top outer wall of the support rod 511, and the top outer wall of the support plate 510 is provided with a plurality of arc-shaped slots adapted to the fire extinguisher cylinder 7, a group of fifth cylinders 56 are fixed to the inner wall of the support plate 505, a push-pull rod 508 is fixed to the output shaft of the fifth cylinder 56, and the push-pull rod 508 is fixed to the stripper plate 509;

[0053] The plurality of air injection pipes 507 are fixed on the outer wall of one side of the inflatable plate 57, and there is a gap between the outer wall of the air injection pipe 507 and the inner wall of the stripper plate 509;

[0054] A set of reinforcing rods 506 are fixed to the inner wall of the support plate 505, the inner wall of the inflatable plate 57 is fixed to the outer wall of the reinforcing rods 506, and the stripper plate 509 is slidably connected to the outer wall of the reinforcing rods 506;

[0055] A set of bearings 504 are fixed to the outer wall of the movable frame 54, and a rotating shaft 501 is rotatably connected to the inner wall of the bearing 504. Gears 503 are fixed to the outer walls of both ends of the rotating shaft 501. A set of rack plates 502 are fixed to the outer wall of one side of the fixed frame 51, and the gears 503 are meshed with the rack plates 502.

[0056] A pressure block 59 is fixed to the output end of the seventh cylinder 52 .

[0057] After placing a plurality of neatly arranged fire extinguisher cylinders 7 on the top of the support plate 510 on the outer wall of the support rod 511 through the clamping and conveying mechanism 4, the control panel will control the seventh cylinder 52 to push the pressure block 59 to move forward, and push the fire extinguisher cylinder 7 forward through the pressure block 59, so that the opening at one end of the fire extinguisher cylinder 7 is inserted into the outer wall of the jet pipe 507 protruding from one end of the stripping plate 509, and the jet pipe 507 is connected to the external gas supply mechanism through the gas supply pipeline, so that gas is transported to the inside of the fire extinguisher cylinder 7 through the external gas supply mechanism, and then the control panel controls the eighth cylinder 53 to push the movable frame 54 to move downward as a whole, so that the fire extinguisher cylinder 7 is immersed in the water inside the detection pool 58, and then the staff judges whether the air tightness of the fire extinguisher cylinder 7 is intact by observing whether the corresponding fire extinguisher cylinder 7 emits bubbles to the outside;

[0058] After the test is completed, the control panel controls the eighth cylinder 53 to drive the movable frame 54 to move upward and reset, and then controls the seventh cylinder 52 to reset, releasing the squeezing of the pressure block 59 on one end of the fire extinguisher cylinder 7. At the same time, the fifth cylinder 56 drives the stripper plate 509 to move back, thereby pushing out the fire extinguisher cylinder 7 inserted on the outer wall of the jet pipe 507. Subsequently, the fire extinguisher cylinder 7 after the test is completed can be clamped and conveyed to the discharge mechanism 6 by the clamping and conveying mechanism 4;

[0059] When the eighth cylinder 53 pushes the movable frame 54 to move up and down, the movable frame 54 will drive the rotating shaft 501 connected to the outer wall through the bearing 504 to move up and down, thereby driving the gears 503 at both ends of the rotating shaft 501 to rotate up and down on one side of the rack plate 502, thereby guiding and limiting the movable frame 54 moving up and down, and improving the stability of the movable frame 54 when moving up and down.

[0060] like Figure 1 、 Figure 6 and Figure 7 As shown, the clamping and conveying mechanism 4 includes a square tube frame 402, a linear guide 41, a synchronous conveyor belt 42, a servo motor 401, a movable plate 43, a movable plate 48 and a sixth cylinder 45. The square tube frame 402 is fixed to an outer wall of one side of the fixed frame 51, the linear guide 41 is fixed to an outer wall of one side of the square tube frame 402, the servo motor 401 is fixed to an outer wall of one side of the square tube frame 402, the synchronous conveyor belt 42 is transmission-connected to the output shaft of the servo motor 401, a group of movable plates 43 are fixed to the outer wall of the synchronous conveyor belt 42, the movable plate 48 is slidably connected to the outer wall of the movable plate 43, the sixth cylinder 45 is fixed to the outer wall of the movable plate 48, and the output shaft of the sixth cylinder 45 is fixed to an outer wall of one side of the movable plate 43;

[0061] The movable plate 43 is slidably connected to the outer wall of the linear guide rail 41;

[0062] The outer wall of the bottom of the movable plate 48 is fixed with a conveying frame 46 by screws; the outer wall of the bottom of the conveying frame 46 is provided with a plurality of arc-shaped grooves adapted to the outer wall of the fire extinguisher cylinder 7;

[0063] A plurality of fourth cylinders 47 are fixed to the outer wall of the conveying frame 46 , and a second electromagnet 49 is fixed to the output shaft of the fourth cylinder 47 ;

[0064] A connecting rod 44 is fixed to the outer wall of the top of the movable plate 43;

[0065] The control panel controls the servo motor 401 to drive the synchronous conveyor belt 42 to rotate, thereby driving a group of movable plates 43 fixedly connected by connecting rods 44 to move synchronously on one side of the linear guide rail 41. When one of the movable plates 43 moves to the top of the continuous feeding mechanism 3, the movable plate 43 on the other side will just move to the top of the inflation pressure test mechanism 5. At this time, the control panel controls the sixth cylinder 45 to push the output shaft to move forward, thereby driving the conveying frame 46 at the bottom of the movable plate 48 to move downward to the outer wall of the multiple fire extinguisher cylinders 7 placed on the outer wall of the first feeding frame 32. Then the control panel controls the second electromagnet 49 to open, and at the same time controls the fourth cylinder 47 to push the second electromagnet 49 to move to the outer wall of the fire extinguisher cylinder 7, so that the multiple fire extinguisher cylinders 7 can be adsorbed to the bottom of the conveying frame 46 by magnetic force. Then the control panel controls the sixth cylinder 45 to drive the movable plate 48 to move upward, thereby grabbing the multiple fire extinguisher cylinders 7 conveyed in sequence through the continuous feeding mechanism 3;

[0066] At the same time, the movable plate 43 located at the top of the inflation and pressure testing mechanism 5 repeats the above steps to grab the multiple fire extinguisher cylinders 7 that have been tested and placed on the top of the support plate 510. Then the control panel controls the servo motor 401 to rotate in the opposite direction for the corresponding number of circles, so that the multiple fire extinguisher cylinders 7 to be tested can be moved to the top of the inflation and pressure testing mechanism 5, and at the same time, the multiple fire extinguisher cylinders 7 that have completed testing can be moved to the top of the discharge mechanism 6. Then the control panel controls the sixth cylinder 45 to drive the conveying frame 46 to move downward, and place the multiple fire extinguisher cylinders 7 that have completed testing on the discharge mechanism 6, and place the multiple fire extinguisher cylinders 7 to be tested on the support plate 510. Then the second electromagnet 49 is controlled to be closed, and the fourth cylinder 47 is controlled to drive the second electromagnet 49 to move upward and reset, thereby releasing the adsorption and fixation of the multiple fire extinguisher cylinders 7, so that the multiple fire extinguisher cylinders 7 are continuously clamped and conveyed by the clamping and conveying mechanism 4, thereby improving the air tightness detection efficiency of the fire extinguisher cylinders 7.

[0067] like Figure 1 and 11As shown, the discharging mechanism 6 includes a discharging trough 61, a ninth air cylinder 62, a second third-rod cylinder 63, a lifting plate 64 and a pushing cylinder 65. The discharging trough 61 is rotatably connected to an inner wall of one side of the detection bracket 1, the bottom outer wall of the ninth air cylinder 62 is fixed to the outer wall of the detection bracket 1, the output shaft of the ninth air cylinder 62 is rotatably connected to the bottom outer wall of the discharging trough 61, the second third-rod cylinder 63 is fixed to an outer wall of one side of the discharging trough 61, the lifting plate 64 is fixed to the moving end of the second third-rod cylinder 63, a rectangular through hole is opened on the outer wall of the discharging trough 61, the lifting plate 64 is clamped on the inner wall of the rectangular through hole, the pushing cylinder 65 is fixed to an outer wall of one side of the discharging trough 61, and the output shaft of the pushing cylinder 65 passes through an outer wall of one side of the discharging trough 61;

[0068] When the unqualified fire extinguisher cylinders 7 move to one end of the discharge chute 61, the staff can control the second and third rod cylinders 63 to push the lifting plate 64 to move upward, thereby lifting the qualified fire extinguisher cylinders 7, making it convenient for the staff to recycle the qualified fire extinguisher cylinders 7. When the unqualified fire extinguisher cylinders 7 move to one end of the discharge chute 61, the staff can control the pushing cylinder 65 to push the unqualified fire extinguisher cylinders 7 out of the opening on one side of the discharge chute 61 through the output shaft, so that the unqualified fire extinguisher cylinders 7 fall into the collection box at the opening on one side of the discharge chute 61, thereby completing the classified recycling of the fire extinguisher cylinders 7.

[0069] Working principle: When the fire extinguisher cylinder 7 is moved from the previous processing step to the side of the grabbing mechanism 2 through the conveyor belt, the first three-rod cylinder 24 on the side of the second L-shaped plate 23 will drive the swing frame 201 to move downward by a set distance, so that the first electromagnet 27 at the bottom of the mounting plate 28 moves to the outer wall of the fire extinguisher cylinder 7, and then the control panel controls the first electromagnet 27 to be energized, and the fire extinguisher cylinder 7 is adsorbed and fixed by magnetic force. Then the first three-rod cylinder 24 drives the swing frame 201 to move upward and reset, and at the same time controls the rotating cylinder 207 to drive the swing frame 201 and the mounting plate 28 to rotate ninety degrees toward the side of the continuous feeding mechanism 3, so that the fire extinguisher cylinder 7 can be rotated. At the same time, it moves ninety degrees, following the mounting plate 28 to the top of the continuous feeding mechanism 3, and then the first three-rod cylinder 24 drives the swing frame 201 to move downward by a corresponding distance again, thereby placing the fire extinguisher cylinder 7 after adjusting the direction onto the continuous feeding mechanism 3, and then the control panel controls the first electromagnet 27 to cut off the power, and at the same time controls the first cylinder 26 to push the push block 29 to move downward and reciprocating, pushing the fire extinguisher cylinder 7 completely into the continuous feeding mechanism 3, and then the control panel controls the rotating cylinder 207 and the first three-rod cylinder 24 again to drive the swing frame 201 and the mounting plate 28 to reset, preparing to grab and transport the next fire extinguisher cylinder 7 that is transported by the conveyor belt and needs to be tested for air tightness.

[0070] After the fire extinguisher cylinder 7 is placed inside the outermost pair of arc-shaped grooves on the first feed frame 32 through the grabbing mechanism 2, the control panel will then control the third cylinder 34 to push the second feed frame 35 to move upward to a corresponding height as a whole, thereby lifting the fire extinguisher cylinder 7 on the first feed frame 32 to a certain height through the arc groove on the outer wall of the second feed frame 35, so that the fire extinguisher cylinder 7 is lifted up from the arc groove at the top of the first feed frame 32 by the second feed frame 35, and then the control panel controls the second cylinder 33 to push the movable block 37 to move forward as a whole. When the third cylinder 34 moves to the fixed block 38 After reaching one end of the bottom rectangular through groove, the fire extinguisher cylinder 7 on the top of the second feeding frame 35 will move to the top of the next arc groove under the drive of the third cylinder 34, and then the control panel controls the third cylinder 34 to drive the second feeding frame 35 to move downward and reset, thereby transporting the fire extinguisher cylinder 7 in sequence to the next arc groove on the outer wall of the first feeding frame 32, and then the control panel controls the second cylinder 33 to drive the movable block 37 to move backward and reset, and then repeat the above steps, so that the fire extinguisher cylinder 7 placed on the first feeding frame 32 by the grabbing mechanism 2 can be stably arranged and transported forward in sequence;

[0071] When the fire extinguisher cylinder 7 moves to the innermost arc groove under the conveyance of the second feeding frame 35, the clamping and conveying mechanism 4 will grab the multiple fire extinguisher cylinders 7 arranged in sequence on the top of the second feeding frame 35 under the control of the control panel and convey them to the inside of the inflation and pressure testing mechanism 5 for air tightness testing.

[0072] After placing a plurality of neatly arranged fire extinguisher cylinders 7 on the top of the support plate 510 on the outer wall of the support rod 511 through the clamping and conveying mechanism 4, the control panel will control the seventh cylinder 52 to push the pressure block 59 to move forward, and push the fire extinguisher cylinder 7 forward through the pressure block 59, so that the opening at one end of the fire extinguisher cylinder 7 is inserted into the outer wall of the jet pipe 507 protruding from one end of the stripping plate 509, and the jet pipe 507 is connected to the external gas supply mechanism through the gas supply pipeline, so that gas is transported to the inside of the fire extinguisher cylinder 7 through the external gas supply mechanism, and then the control panel controls the eighth cylinder 53 to push the movable frame 54 to move downward as a whole, so that the fire extinguisher cylinder 7 is immersed in the water inside the detection pool 58, and then the staff judges whether the air tightness of the fire extinguisher cylinder 7 is intact by observing whether the corresponding fire extinguisher cylinder 7 emits bubbles to the outside;

[0073] After the detection is completed, the control panel controls the eighth cylinder 53 to drive the movable frame 54 to move upward and reset, and then controls the seventh cylinder 52 to reset, releasing the squeezing of the pressure block 59 on one end of the fire extinguisher cylinder 7. At the same time, the fifth cylinder 56 drives the stripping plate 509 to move back, thereby pushing out the fire extinguisher cylinder 7 inserted on the outer wall of the jet pipe 507. Then, the fire extinguisher cylinder 7 after the detection can be clamped and conveyed to the discharging mechanism 6 through the clamping and conveying mechanism 4.

[0074] The control panel controls the servo motor 401 to drive the synchronous conveyor belt 42 to rotate, thereby driving a group of movable plates 43 fixedly connected by connecting rods 44 to move synchronously on one side of the linear guide rail 41. When one of the movable plates 43 moves to the top of the continuous feeding mechanism 3, the movable plate 43 on the other side will just move to the top of the inflation pressure test mechanism 5. At this time, the control panel controls the sixth cylinder 45 to push the output shaft to move forward, thereby driving the conveying frame 46 at the bottom of the movable plate 48 to move downward to the outer wall of the multiple fire extinguisher cylinders 7 placed on the outer wall of the first feeding frame 32. Then the control panel controls the second electromagnet 49 to open, and at the same time controls the fourth cylinder 47 to push the second electromagnet 49 to move to the outer wall of the fire extinguisher cylinder 7, so that the multiple fire extinguisher cylinders 7 can be adsorbed to the bottom of the conveying frame 46 by magnetic force. Then the control panel controls the sixth cylinder 45 to drive the movable plate 48 to move upward, thereby grabbing the multiple fire extinguisher cylinders 7 conveyed in sequence through the continuous feeding mechanism 3;

[0075] At the same time, the movable plate 43 located at the top of the inflation and pressure testing mechanism 5 repeats the above steps to grab the multiple fire extinguisher cylinders 7 that have been tested and placed on the top of the support plate 510. Then the control panel controls the servo motor 401 to rotate in the opposite direction for the corresponding number of circles, so that the multiple fire extinguisher cylinders 7 to be tested can be moved to the top of the inflation and pressure testing mechanism 5, and the multiple fire extinguisher cylinders 7 that have completed testing can be moved to the top of the discharge mechanism 6. Then the control panel controls the sixth cylinder 45 to drive the conveying frame 46 to move downward, and place the multiple fire extinguisher cylinders 7 that have completed testing on the discharge mechanism 6, and place the multiple fire extinguisher cylinders 7 to be tested on the support plate 510. Then the second electromagnet 49 is controlled to be closed, and the fourth cylinder 47 is controlled to drive the second electromagnet 49 to move upward and reset, thereby releasing the adsorption and fixation of the multiple fire extinguisher cylinders 7, so that the multiple fire extinguisher cylinders 7 are continuously clamped and conveyed by the clamping and conveying mechanism 4.

[0076] When the unqualified fire extinguisher cylinders 7 move to one end of the discharge chute 61, the staff can control the second and third rod cylinders 63 to push the lifting plate 64 to move upward, thereby lifting the qualified fire extinguisher cylinders 7, making it convenient for the staff to recycle the qualified fire extinguisher cylinders 7. When the unqualified fire extinguisher cylinders 7 move to one end of the discharge chute 61, the staff can control the pushing cylinder 65 to push the unqualified fire extinguisher cylinders 7 out of the opening on one side of the discharge chute 61 through the output shaft, thereby allowing the unqualified fire extinguisher cylinders 7 to fall into the collection box at the opening on one side of the discharge chute 61.

[0077] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
