[0019] like Figures 1-4 As shown, this utility model discloses a fire extinguisher cylinder feeding device, including a frame 1. A material trough positioning mechanism 2 is connected to the lower part of the frame 1 for precisely positioning the cylinder 6. Foot pads 5 are connected to the four corners of the lower end of the frame 1. The material trough positioning mechanism 2 includes: a material discharge trough 21, a fixed platform 22, a placement frame 25, a first electric cylinder 23, and a push plate 24. The material discharge trough 21 is obliquely fixedly connected to the lower side of the frame 1, allowing the cylinder 6 to roll within the material discharge trough 21. The fixed platform 22 is fixedly connected to the lower part of the frame 1. Two first electric cylinders 23 are arranged opposite each other on both sides of the fixed platform 22. The output shafts of both first electric cylinders 23 are connected to the push plate 24, allowing the two first electric cylinders 23 to drive the push plate 24 to move. The placement frame 25 is fixedly connected to the middle of the fixed platform 22 for placing the cylinder 6. The height of the material discharge trough 21 is higher than the placement frame 25, allowing the cylinder 6 to roll onto the placement frame 25. The upper part of the frame 1 is connected to a slide rail 7, and a lifting mechanism 3 is slidably connected to the slide rail 7, allowing the lifting mechanism 3 to slide on the slide rail 7. The upper part of the frame 1 is also connected to a wire changing mechanism 4 that drives the lifting mechanism 3 to move, and one end of the wire changing mechanism 4 is fixedly connected to the side of the lifting mechanism 3.
[0020] The lifting mechanism 3 includes: a slider 31, a movable plate 32, a fixed plate 310, a first sliding rod 34, a connecting plate 35, a buffer assembly 38, a connecting plate 37, a magnetic clamp 39, a second electric cylinder 33, a third electric cylinder 36, and a push block 311. The slider 31 is slidably connected to the slide rail 7, and the movable plate 32 is fixedly connected to the upper part of the slider 31, allowing the slider 31 to move the movable plate 32. One end of the second electric cylinder 33 is fixedly connected to the upper part of the movable plate 32, and the output shaft of the second electric cylinder 33 passes through the movable plate 32 and is slidably connected to it, causing the movable plate 32 to move the second electric cylinder 33 accordingly. The output shaft of the second electric cylinder 33 is fixedly connected to the fixed plate 310, and the output shaft of the second electric cylinder 33 moves the fixed plate 310. Multiple first sliding rods 34 pass through the movable plate 32 and are slidably connected to it, and one end of each of the multiple first sliding rods 34 is fixedly connected to the connecting plate 35, allowing the multiple first sliding rods 34 to move accordingly. The other ends of multiple first sliding rods 34 are fixedly connected to the fixed plate 310, making the fixed plate 310 more stable when moving. The buffer assembly 38 is located between the connecting plate 37 and the fixed plate 310 to prevent the connecting plate 37 from being subjected to hard contact. A third electric cylinder 36 is connected to each end of the connecting plate 37. The output shafts of the two third electric cylinders 36 are fixedly connected to the push block 311, and the third electric cylinders 36 drive the push block 311 to move. The magnetic clamp 39 is fixedly connected to the lower end of the connecting plate 37. The magnetic clamp 39 is composed of magnets to attract the cylinder 6.
[0021] The line changing mechanism 4 is a fourth electric cylinder 41. One side of the fourth electric cylinder 41 is fixedly connected to the frame 1, and one end of the output shaft of the fourth electric cylinder 41 is fixedly connected to the moving plate 32. The fourth electric cylinder 41 drives the moving plate 32 to move.
[0022] The buffer assembly 38 includes a second slide rod 382 and a spring 381. One end of the second slide rod 382 is fixedly connected to the connecting plate 37, and the other end of the second slide rod 382 passes through and is slidably connected to the moving plate 32. The top of the second slide rod 382 is slightly thicker to prevent the connecting plate 37 from falling off. The second slide rod 382 passes through the spring 381, which is located between the moving plate 32 and the connecting plate 37, so that when the connecting plate 37 is subjected to force, the spring 381 is compressed, thereby relieving the force.
[0023] The above-described working process is as follows: The cylinder 6 enters the discharge trough 21 via a conveyor line (not shown in the text), where it rolls. The cylinder 6 rolls onto the placement frame 25, at which point the two first electric cylinders 23 move the push plate 24 to push the cylinder 6 directly below the magnetic clamp 39. The second electric cylinder 33 is activated, causing the fixing plate 310 and connecting plate 37 to move. At this point, the magnetic clamp 39 contacts the cylinder 6, attracting it. When the magnetic clamp 39 contacts the cylinder 6, it and the connecting plate 37 move towards the fixing plate 310, compressing the spring 381 and reducing the contact force between the magnetic clamp 39 and the cylinder 6 to avoid hard contact. Then, the second electric cylinder 33 pulls the fixing plate 310 and connecting plate 37 back, causing the cylinder 6 to rise. The fourth electric cylinder 41 is activated to move the moving plate 32 and the cylinder 6. When the moving plate 32 moves to the end of the slide rail 7, the third electric cylinder 36 is activated to move the push block 311 to push the cylinder 6 out of the magnetic clamp 39, so that the cylinder 6 enters the next station.
[0024] The above solution has the following advantages: the material trough positioning mechanism 2 automatically aligns the cylinder 6, making it easier for the lifting mechanism 3 to move the cylinder 6 to the next workstation; the simultaneous activation of the two first electric cylinders 23 pushes the push plate 24 to the fixed range of the magnetic clamp 39, improving the gripping accuracy of the cylinder 6; the magnetic clamp 39 attracts and lifts the cylinder 6, and the buffer assembly 38 provides a spring-loaded effect when the magnetic clamp 39 contacts the cylinder 6, preventing damage to the equipment due to hard contact; the line changing assembly pushes the connecting plate 37 and the magnetic clamp 39, allowing the magnetic clamp 39 to move the cylinder 6 to the next workstation, thus achieving efficient transportation of the cylinder 6.
[0025] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
