DETAILED DESCRIPTION

[0022] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific implementation method described herein is only an optimal embodiment of the present invention, which is only used to explain the present invention and does not limit the scope of protection of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Example 1: Please refer to the attached Figure 1 - Attachment Figure 4 The embodiment of the present invention provides a safety protection device for a stamping machine, including a stamping cabinet 1, a fixed frame 2 is fixedly connected to one side of the stamping cabinet 1, a motor 3 is arranged inside the fixed frame 2, a rotating column 4 is fixedly connected to the output end of the motor 3, the rotating column 4 is rotatably connected to the inside of the stamping cabinet 1, a rotating column 2 5 is rotatably connected to the inside of the stamping cabinet 1, a driving wheel 6 is fixedly connected to the outer wall of the rotating column 1 4, a driven wheel 7 is fixedly connected to the outer wall of the rotating column 2 5, a belt 8 is arranged between the driving wheel 6 and the driven wheel 7, a gear 9 is fixedly connected to the outer wall of the rotating column 1 4, a fixed frame 10 is fixedly connected to one side of the stamping cabinet 1, a cleaning roller 11 is arranged on the outer wall of the rotating column 2 5, and a protective frame is slidably connected to the inside of the fixed frame 10 12, a rack 13 is fixedly connected inside the protective frame 12, and the gear 9 is meshed with the rack 13. A cleaning brush 14 is provided on one side of the protective frame 12, and the cleaning brush 14 is fixedly connected to one side of the stamping cabinet 1. A fixing column 15 is fixedly connected to the other side of the protective frame 12, and a rubber ball 16 is fixedly connected to one end of the fixing column 15. The bottom of the rubber ball 16 touches the fixed frame 10, and a magnetic strip 17 is provided at the bottom of the rubber ball 16. One side of the magnetic strip 17 is fixedly connected to the other side of the protective frame 12, and a collecting frame 18 is fixedly connected to one side of the protective frame 12. A cleaning component is provided inside the stamping cabinet 1, a quick-release component is provided inside the cleaning roller 11, and a sensor component is provided on one side of the stamping cabinet 1.

[0024] Specifically, the motor 3 serves as the power source of the system and is responsible for driving the rotating column 4. The rotation of the rotating column 4 is not only smooth but also stable. It directly drives the gear 9 to rotate synchronously. The precise engagement between the gear 9 and the rack 13 ensures the efficiency and accuracy of power transmission, thereby driving the protective frame 12 to slide smoothly along the fixed frame 10. During this process, the fixed column 15 is synchronously displaced, driving the rubber ball 16 to slide along the fixed frame 10 to a predetermined position, and accurately controlling the stop position of the protective frame 12 to ensure safe isolation; the main function of the protective frame 12 is to form an enclosed space in the stamping operation area, and cooperate with the tempered glass windows on both sides of the stamping cabinet 1 to effectively isolate splashing debris and lubricating oil, and protect the operator and the surrounding environment from pollution. This design not only optimizes the working environment, but also significantly improves the safety of operation; after completing the operation, the reverse drive of the motor 3 The automatic function is started, causing the rotating column 4 and the gear 9 to rotate in the opposite direction, and the protective frame 12 is smoothly pulled up through the rack 13. When the protective frame 12 is raised to the highest position, the design of the magnetic strip 17 allows it to be closely adsorbed with the fixing frame 10, fixing the position of the protective frame 12, providing convenience for subsequent operations; at the same time, the cleaning brush 14 is automatically started to effectively clean the debris and lubricating oil on the inner surface of the protective frame 12, ensuring that all residues fall into the collection frame 18. In addition, the rotation of the rotating column 4 also drives the driving wheel 6 and the driven wheel 7 to rotate synchronously through the belt 8, further driving the rotating column 2 5 and the cleaning roller 11, and performing secondary cleaning on the inner surface of the protective frame 12 to ensure that it is clean and pollution-free, and prepare perfect working conditions for the next use; this not only greatly improves production efficiency, but also provides operators with a safer and cleaner working environment.

[0025] Please see attached Figure 5 - Attachment Figure 7 The cleaning component includes a water tank 19, which is fixedly connected to the rear side of the stamping cabinet 1. One end of a connecting pipe 20 is arranged inside the water tank 19. The other end of the connecting pipe 20 passes through the stamping cabinet 1 and is fixedly connected to a water pipe 21. The water pipe 21 is fixedly connected to the inside of the stamping cabinet 1. A micro water pump 22 is arranged inside the water pipe 21. A spray head 23 is fixedly connected to one end of the water pipe 21. A filter plate 24 is arranged inside the spray head 23.

[0026] Specifically, the water pump equipped in the water tank 19 is responsible for conveying the clean water to the key position through the connecting pipe 20 and the water pipe 21. The design of the water pump ensures the continuity and stability of the water flow, so that the clean water can be continuously supplied to meet the cleaning needs of the system. Through the water pipe 21, the clean water is pressurized and conveyed. This pressurized design allows the water flow to have sufficient power to effectively flush various residues on the inside of the protective frame 12; then, the clean water is evenly distributed on the inside of the protective frame 12 through the spray head 23 to achieve a comprehensive cleaning effect. The spray head 23 is cleverly designed to form the water flow into a fine mist, which helps to improve the cleaning efficiency and ensure the inside of the protective frame 12. Every corner can be thoroughly cleaned. In addition, in order to prevent debris from entering the water system and causing blockage during the cleaning process, a filter plate 24 is installed in the spray head 23. This filter plate 24 has a high-efficiency filtering ability and can intercept small debris and other impurities to ensure smooth water flow; the cleaned water flow carries the removed debris and dirt and finally collects in the collection frame 18. This collection frame 18 is designed to be easy to clean and maintain, supports fast drainage and debris removal, thereby simplifying subsequent cleaning work; the entire cleaning process not only improves the service life of the equipment, but also ensures the hygiene standards of the production environment. It is an efficient and environmentally friendly solution.

[0027] Please see attached Figure 8 The quick-release assembly includes a spring 25, which is arranged inside the cleaning roller 11. The cleaning roller 11 is bilaterally symmetrical and interlocked. One end of the spring 25 is fixedly connected to the inside of the cleaning roller 11, and the other end of the spring 25 is fixedly connected to a sliding column 26. A ball 27 is fixedly connected to one side of the sliding column 26. The outer wall of the sliding column 26 is fixedly connected to a limit block 28, and the limit block 28 is slidably connected to the inside of the cleaning roller 11.

[0028] Specifically, the design of the cleaning roller 11 takes into account the maintenance and cleaning needs after long-term use. In order to facilitate the operator to thoroughly clean the cleaning roller 11, its structure specially adopts a detachable mechanism to ensure that internal cleaning and necessary maintenance work can be easily performed; specifically, the cleaning roller 11 is designed as a two-half structure, which can be separated by simple manual operation. During the separation process, the force applied by the operator first acts on the ball 27. This design makes the ball 27 the first contact point for transmitting force. Subsequently, this force is transmitted through the slide column 26, directly affecting the spring 25. The spring 25 is located in the internal structure of the cleaning roller 11. Its main function is to absorb and buffer the force generated during the separation process, thereby avoiding damage to the structure of the cleaning roller 11. The spring 25 is constructed to be damaged; under the action of force, the spring 25 is compressed and its volume is reduced in the confined space. This change allows the ball 27 and the slide post 26 to slide inward along a preset path under the guidance of the limit block 28. This inward sliding is the key to the separation mechanism, which enables the slide post 26 to be further pushed into the interior of the cleaning roller 11, thereby unlocking the connection between the two halves; when the slide post 26 reaches its final position, the two halves of the cleaning roller 11 can be easily separated manually. The smoothness of this separation operation is due to the carefully designed internal mechanical structure, which ensures that it can be efficiently executed without the need for additional tools. In addition, this design not only facilitates the routine cleaning and maintenance of the cleaning roller 11, but also significantly improves the service life and performance stability of the equipment.

[0029] Please see attached Figure 1 The sensing component includes a pressure plate 29 and a laser sensor 30. The pressure plate 29 is arranged on one side of the stamping cabinet 1. The laser sensor 30 is fixedly connected to the inside of the stamping cabinet 1. The pressure plate 29 and the laser sensor 30 are both electrically connected to the stamping cabinet 1.

[0030] Specifically, the PLC in the stamping cabinet 1 is designed to be able to sense whether the operator is near the pressure plate 29. When it is detected that the operator has left the working area, the PLC will automatically instruct the equipment to stop operating. This function is to prevent the equipment from accidentally starting up when unattended, thereby greatly reducing potential safety risks. This automatic shutdown function is based on real-time monitoring of the dynamics of personnel in the working area, ensuring that the equipment can only operate when the operator is in the correct position; in addition, in order to prevent the operator from accidentally or mistakenly opening the protective frame 12 during the operation of the stamping cabinet 1, the equipment is also equipped with laser sensors 30. These sensors are responsible for monitoring the position of the protective frame 12 and whether any objects are accidentally left in the potentially dangerous area. If the protective frame 12 suddenly rises during the stamping operation, the laser sensor 30 will immediately fail to detect the normal closed position of the protective frame 12, and this abnormal signal will be quickly transmitted to the PLC system; after receiving the signal, the PLC will perform an emergency stop operation on the stamping cabinet 1. This emergency braking mechanism is based on a quick response design to the feedback of the laser sensor 30, ensuring that when any potentially dangerous operating error occurs, all running mechanical actions can be immediately interrupted to prevent possible injury accidents.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

[0032] Working principle: When the stamping operation is carried out, the motor can be driven to drive the rotating column 1 to rotate. When the rotating column 1 rotates, it can drive the gear to rotate synchronously, so that the gear can mesh with the tooth marks between the gear and the rack, so that the rack drives the protective frame to slide under the restriction of the fixed frame. When the fixed column moves synchronously with the protective frame and drives the rubber ball to move synchronously, the movement stops when the rubber ball touches the fixed frame. At this time, the protective frame cooperates with the tempered glass windows on both sides of the stamping cabinet to seal the working area of ​​the stamping cabinet. The debris and lubricating oil generated during the operation in the stamping cabinet will be blocked by the protective frame, and after the operation is completed, the electric The machine reverse drives the rotating column 1 and the gear to rotate in the opposite direction, so that the protection frame is pulled up by the rack. When the corresponding protection frame rises to the highest position, the corresponding magnetic strip will fix the height of the protection frame by adsorbing with the fixed frame, and when the protection frame rises, the corresponding cleaning brush will clean the debris and lubricating oil splashed on the inner surface of the protection frame, so that they can fall to the collection frame position at the bottom for collection. At the same time, the corresponding rotating column 1 can also drive the driving wheel to rotate synchronously when it rotates, and then the driven wheel drives the rotating column 2 to rotate synchronously through the transmission of the belt. The corresponding rotating column 2 will drive the cleaning roller to rotate synchronously when it rotates, so that the inner surface of the protection frame is cleaned after passing through After brushing, it can be cleaned again with the cleaning roller, and before cleaning, the cleaning water can be transported through the connecting pipe and the water pipe by the water pump in the water tank. Finally, the clean water can be flushed through the inner side of the protective frame in the sprinkler head through the pressurized water pipe, and the corresponding flushing water will also fall into the position of the collection frame for collection. At the same time, the filter plate in the corresponding sprinkler head can prevent the residual debris during the cleaning operation from entering the water pipe through the sprinkler head and causing blockage and other problems. When the corresponding cleaning roller needs to be cleaned after a long period of use, it can be split into two halves by force. When splitting, the ball will be acted upon by the force first, and then the force will be transmitted to the position of the spring through the sliding column, so that the spring is When squeezed, the space occupied by the spring is compressed, so that the corresponding ball bearing and sliding column can slide smoothly into the deep inside of the cleaning roller under the restriction of the limit block, so that the cleaning rollers can be successfully separated. In order to further ensure the safety of the equipment, when the operator leaves the pressure plate, the corresponding stamping cabinet will stop the operation through the PLC set inside it to prevent the equipment from being operated without the supervision of the operator. When the operation inside the stamping cabinet is still in progress, if the corresponding protective frame suddenly rises, the corresponding laser sensor will not be able to detect the existence of objects in the protective frame position, thereby causing the operation of the stamping cabinet to stop urgently to prevent employees from accidentally touching the protective frame to open the protective frame and causing danger.

The scope of the present invention includes but is not limited to the present specific embodiments.
