[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This embodiment provides a technical solution: a processing device for the end of a fire extinguisher cylinder, including a cylinder 1;

[0020] Cylinder 1: Its inner arc surface is provided with a conical ring 2. The middle part of the conical ring 2 is rotatably connected to a rotating column 3 via a bearing. The upper end of the rotating column 3 is provided with a sliding groove 4. The sliding groove 4 is slidably connected to a slider 5. The lower surface of the slider 5 is provided with a top post 6. The top post 6 is installed in conjunction with the conical ring 2. The upper end of the slider 5 is installed with a grinding plate 7. When the fire extinguisher cylinder is inserted into the cylinder 1 and pressed down, the fire extinguisher cylinder pushes the rotating column 3 to move down. The slider 5 moves down with the rotating column 3. The lower end of the top post 6 moves along the conical arc surface of the conical ring 2, driving the slider 5 to move towards the fire extinguisher cylinder synchronously and with the same amplitude until the grinding plate 7 contacts the end of the fire extinguisher cylinder. The end of the fire extinguisher cylinder is ground by the movement of the grinding plate 7. The rotating column 3 includes a rotating cylinder 31. The sliding column 32 and the disc 34 are connected to the middle of the conical ring 2 via a bearing. The sliding column 32 is vertically slidably connected inside the rotating cylinder 31. The upper end of the sliding column 32 extends out of the rotating cylinder 31 and is provided with a disc 34. The upper surface of the disc 34 is provided with a sliding groove 4. The middle of the upper surface of the disc 34 is rotatably connected to a turntable 14 via a rotating shaft. The relative sliding between the sliding column 32 and the rotating cylinder 31 provides space for the downward movement of the disc 34. During the manufacturing process, the fire extinguisher cylinder comes into contact with the turntable 14. The relative rotation between the turntable 14 and the disc 34 reduces the force exerted by the rotation of the disc 34 on the fire extinguisher cylinder. The rotating column 32 also includes a tension spring 33, which is movably sleeved on the outer arc surface of the sliding column 32. The lower end of the tension spring 33 is connected to the sliding column 32. The limiting slide of column 32 is fixedly connected, and the upper end of tension spring 33 is fixedly connected to the top wall of rotating drum 31 to limit the initial position of disk 34. It also includes control switch 9, which is located on the right side of cylinder 1. The input end of control switch 9 is electrically connected to an external power source to control the start and stop of the whole device. A motor 8 is provided at the lower end of cylinder 1. The upper end of the output shaft of motor 8 is fixedly connected to the middle of rotating drum 31. The input end of motor 8 is electrically connected to the output end of control switch 9 to provide power for the rotation of rotating drum 31. Sliding columns 10 are slidably connected to the support plate surface at the upper end of slider 5. A grinding plate 7 is provided between the ends of the two sliding columns 10 of the same slider 5. A spring 11 is provided between the grinding plate 7 and slider 5. The spring 11 is movably sleeved on the sliding plate 10. After the grinding plate 7 contacts the fire extinguisher cylinder, the outer arc surface of column 10 continues to press down on the fire extinguisher cylinder, causing the slider 5 to move further closer to the fire extinguisher cylinder. At this time, the upper support plate of the sliding column 10 and the slider 5 rotate relative to each other, and the spring 11 contracts. Under the elastic force of the spring 11, the grinding plate 7 applies force to the end of the fire extinguisher cylinder, improving the grinding effect. The inside of the sliding groove 4 is equipped with guide columns 13, which are slidably connected to the guide hole in the middle of the slider 5. The outer arc surface of the guide column 13 is movably fitted with spring 12. The end of spring 12 away from the rotating cylinder 31 is fixedly connected to the slider 5, and the other end of spring 12 is fixedly connected to the inner wall of the sliding groove 4, providing guiding support for the movement of the slider 5. The elastic force of spring 12 is used to...The initial position of slider 5 is restricted to facilitate its reset.

[0021] The working principle of the fire extinguisher cylinder end processing device provided by this utility model is as follows: During the processing of the fire extinguisher cylinder end, the motor 8 is started by the control switch 9. The output shaft of the motor 8 drives the rotating cylinder 31 to rotate. Because the rotating cylinder 31 is vertically slidably connected to the sliding column 32, the relative rotation of the rotating cylinder 31 and the sliding column 32 is restricted. Therefore, the rotating cylinder 31 drives the sliding column 32 and the disc 34 to rotate, and the grinding plate 7 also rotates. Then, the fire extinguisher cylinder is inserted into the cylinder 1. Under the pressure of the fire extinguisher cylinder, the elastic force of the tension spring 33 is overcome, and the sliding column 32 is pushed to slide relative to the rotating cylinder 31. At the same time, the disc 34 drives the slider 5 to move down. During the downward movement of the slider 5, the top column... The lower end of 6 moves along the conical arc surface of the conical ring 2, driving the slider 5 to move towards the fire extinguisher cylinder in sync and with the same amplitude, until the grinding plate 7 contacts the end of the fire extinguisher cylinder, and the end of the fire extinguisher cylinder is ground. During the processing, the fire extinguisher cylinder contacts the turntable 14. Through the relative rotation of the turntable 14 and the disc 34, the force exerted by the rotation of the disc 34 on the fire extinguisher cylinder is reduced. The fire extinguisher cylinder is pressed down, causing the slider 5 to move closer to the fire extinguisher cylinder. At this time, the sliding column 10 and the support plate at the upper end of the slider 5 rotate relative to each other, and the spring 11 contracts. Under the elastic force of the spring 11, the grinding plate 7 applies force to the end of the fire extinguisher cylinder, improving the grinding effect.

[0022] It is worth noting that the motor 8 disclosed in the above embodiments can be freely configured according to the actual application scenario. It is recommended to use a stepper motor of model 42BYHJ01. The control switch 9 is equipped with a switch button corresponding to the motor 8 for controlling its switching operation.

[0023] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
