[0020] In order to clearly and completely describe the objectives, technical solutions of the present utility model, and make the advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are some embodiments of the present utility model, rather than all embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0021] Embodiment 1

[0022] Please refer to Figure 1 - Figure 2 , the present utility model provides a technical solution: a grinding device for steel ball processing, comprising: a bottom plate 1 and a grinding machine 2. The grinding machine 2 is arranged on the upper surface of the bottom plate 1. The grinding is used to grind the steel balls through a rotating barrel. A fence 3 is arranged around the grinding machine 2. The fence 3 only encloses three sides, and a door frame 4 is arranged on the other side. One side of the fence 3 is fixedly installed with the door frame 4. The door frame 4 is used to enter and exit the fence 3. The middle part of the door frame 4 is a door. A railing device 5 is arranged on the door frame 4. The railing device 5 is used to intercept at the position of the door to prevent non-staff from entering and being injured by the rotating barrel. A second groove 9 and a first groove 7 are opened on the upper surface of the door frame 4. The second groove 9 penetrates through the side walls at both ends thereof. The railing device 5 includes a railing body 11. One end of the railing body 11 extends into the second groove 9. A rotating shaft is arranged in the second groove 9. The railing body 11 is rotatably connected to the rotating shaft. The railing body 11 extends into the first groove 7 and is slidably connected thereto. When the railing body 11 is in the open state, it is clamped into the second groove 9. When the railing body 11 makes the door in the closed state, it is clamped into the first groove 7. Two inclined surfaces 14 are arranged at one end of the railing body 11 extending into the first groove 7. To prevent the railing body 11 from deviating from the original rotating surface after long-term use and resulting in being unable to be clamped into the first groove 7, the setting of the two inclined surfaces 14 enables it to be clamped into the first groove 7 even if there is a small amount of deviation.

[0023] In this way, the setting of the fence 3 prevents non-staff from easily touching the grinding machine 2. When the grinding machine 2 is working, the railing is clamped into the first groove 7, making the door unable to be opened. When loading and unloading materials, the staff needs to be inside the fence 3, then the railing body 11 is clamped into the second groove 9. In this way, it will not be easily powered on. Even if someone touches the switch, the machine will not start, effectively ensuring the safety of the staff.

[0024] Embodiment 2

[0025] Please refer to Figure 1 - Figure 4 , on the basis of Embodiment 1, a cylindrical groove 13 is opened on the lower surface of the railing body 11. A contact is arranged in the cylindrical groove 13, and the contact can be powered on. A contact head 8 is arranged at the bottom of the first groove 7, and the contact head 8 can also be powered on. The contact head 8 and the contact are connected to the PLC system. As long as it is triggered, a signal will be sent to the PLC system to make it powered on. The bottom of the contact head 8 is fixedly installed with a first spring 16. One end of the first spring 16 is fixedly connected to the contact head 8, and the other end of the first spring 16 extends into the bottom wall of the first groove 7 and is fixedly connected thereto. The first spring 16 enables the contact head 8 and the contact to be tightly clamped together to prevent poor contact. A PLC system and a display screen are fixedly installed on one side of the door frame 4. The model of the display screen is PK430.

[0026] When power supply is required, the railing body 11 is clamped into the first groove 7. During the clamping process, the contact 8 extends into the cylindrical groove 13 and contacts the contact point in the cylindrical groove 13. Then, when further pressed down, the first spring 16 is compressed. The contact 8 and the contact point are closely attached together under the elastic force of the first spring 16. The contact 8 and the contact point are connected to the PLC system, and as long as it is triggered, a signal will be sent to the PLC system to make it energized.

[0027] Embodiment 3

[0028] Please refer to Figure 3 and Figure 5 , on the basis of Embodiment 2, a push-pull rod 12 is rotatably connected to the lower surface of the railing body 11. The push-pull rod 12 is used to make it more convenient to lift and lower the railing. When the railing is lifted, it will rotate 180 degrees and be clamped into the second groove 9 and placed on the buffer device 10. A buffer device 10 is provided at one end of the second groove 9 far from the rotating shaft. Since the railing falls from the highest point, the buffer device 10 effectively protects the railing from being easily broken. The buffer device 10 includes a fixed block 18 and a slider 21. The fixed block 18 is fixedly installed on the bottom wall of the second groove 9. A sliding groove 19 is formed on the upper surface of the fixed block 18. The slider 21 extends into the sliding groove 19 and is slidably connected thereto. The lower surface of the slider 21 is fixedly connected to a second spring 20. One end of the second spring 20 is fixedly connected to the bottom wall of the sliding groove 19, and the other end of the second spring 20 is fixedly connected to the lower surface of the slider 21. It is the existence of the second spring 20 that plays a certain buffering role.

[0029] During actual use, the setting of the fence 3 prevents non-staff members from easily touching the grinding machine 2. When the grinding machine 2 is working, the railing is clamped into the first groove 7, so that the door cannot pass through. When loading and unloading materials, the staff needs to be inside the fence 3, then the railing body 11 is clamped into the second groove 9, so it will not be easily energized. Even if someone touches the switch, the machine will not start, effectively ensuring the safety of the staff. When the railing body 11 is clamped into the first groove 7, during the clamping process, the contact 8 extends into the cylindrical groove 13 and contacts the contact point in the cylindrical groove 13. Then, when further pressed down, the first spring 16 is compressed. The contact 8 and the contact point are closely attached together under the elastic force of the first spring 16. The contact 8 and the contact point are connected to the PLC system, and as long as it is triggered, a signal will be sent to the PLC system to make it energized. When the railing is clamped into the second groove 9, it can be ensured that it will not be easily energized, effectively ensuring the safety of the staff.
