[0019] Reference Figure 1-Figure 7 A utility knife laser marking machine includes a bracket 1 and a marking head 2 for processing a utility knife. The marking head 2 can mark the utility knife after being powered on. This technical solution is a prior art and will not be elaborated on here.

A positioning rod 6 extending into the positioning platform 3 is installed in the bracket 1, and a handle extending to the outside of the bracket 1 is fixedly installed on the positioning rod 6. The handle drives the positioning rod 6 to penetrate the positioning platform 3 and extend into the bracket 1, thereby locking the position of the positioning platform 3. By providing the hollow grooves 4 on the positioning platform 3, the debris generated during the processing of the utility knife can fall into the collection box 7; A groove 5 corresponding to the sealing cover 10 is provided on the positioning platform 3, a collecting box 7 is placed in the bracket 1, and a mesh plate 8 for intercepting debris is placed in the collecting box 7, the mesh plate 8 is horizontally arranged below the positioning platform 3, the sealing cover 10 is a circular structure with an opening at the bottom, the output end of the cylinder 9 drives the sealing cover 10 to move downward after the extension, and the sealing cover 10 extends into the groove 5 to seal the utility knife during processing to prevent iron chips from overflowing, thereby protecting the operator; The sealing cover 10 is provided with an end 17 for pulling the marking head 2 through a moving part; The moving part includes a motor 11 fixedly mounted on the sealing cover 10, and the output end of the motor 11 is fixedly connected to a screw rod 13 rotatably mounted on the sealing cover 10, a matching nut 14 is provided on the sliding sleeve of the screw rod 13, and an end 17 is provided on the nut 14; Evenly distributed light sensors 15 are fixedly installed in the sealing cover 10. A controller electrically connected to the motor 11 is provided on the sealing cover 10. A lamp body 16 matched with the light sensor 15 is provided on the nut 14. When the motor 11 is powered on, the nut 14 moves. When the nut 14 moves, it drives the lamp body 16 to correspond to one of the light sensors 15. The light source emitted by the lamp body 16 shines on the light sensor 15. When the light sensor 15 senses that the light value exceeds the specified threshold, it immediately sends a closing signal to the motor 11, so that the marking head 2 can process multiple utility knives on the positioning table 3 in sequence. The screw rod 13 is arranged horizontally, and a long hole for guiding the end head 17 is provided on the sealing cover 10. The marking head 2 and the end head 17 extend to the lower end position outside the sealing cover 10. The long hole guides the end head 17, thereby limiting the moving direction of the nut 14. A limiting assembly for limiting the position of the utility knife is installed on the sealing cover 10; The limit assembly includes a motor 2 12 fixedly mounted on the sealing cover 10, and the output end of the motor 2 12 is fixedly connected to a bidirectional screw 18 rotatably mounted on the sealing cover 10, and a bidirectional screw 2 19 is rotatably mounted on the sealing cover 10 and is transmission-connected to the bidirectional screw 18; The bidirectional screw rod 18 and the bidirectional screw rod 2 19 are arranged horizontally correspondingly, and a transmission belt 20 is connected between the bidirectional screw rod 18 and the bidirectional screw rod 2 19 through a coupling. The transmission belt 20 is a synchronous belt, so that the bidirectional screw rod 18 and the bidirectional screw rod 2 19 can rotate synchronously. Two matching nuts 21 are slidingly sleeved on the bidirectional screw rod 18 and the bidirectional screw rod 2 19; A support plate 22 is fixedly mounted on the sealing cover 10, a moving rod 23 is slidably sleeved on the support plate 22, and a connecting rod 24 is connected between the moving rod 23 and the two nuts 21, and a moving plate 25 that is movable against the utility knife is fixedly mounted on the moving rod 23, and the support plate 22 guides the moving rod 23, so that the moving rod 23 can smoothly pull the moving plate 25 when moving, and also limits the moving direction of the nuts 21; The support plate 22 is horizontally arranged, the moving plate 25 and the moving rod 23 extend to the lower position outside the support plate 22, the two ends of the connecting rod 24 are respectively connected to the nut 21 and the moving rod 23 by pins, and the two moving plates 25 are horizontally arranged above the positioning platform 3; After the motor 2 12 is powered on, the moving rod 23 slides on the support plate 22, so that the moving rod 23 drives the moving plate 25 to apply pressure to the utility knife from the top position, thereby enabling the moving plate 25 to apply pressure to multiple utility knives synchronously, and also ensuring the safety of the utility knife itself during processing; A symmetrically arranged pipe 26 connected to the water tank is fixedly mounted on the sealing cover 10, and a nozzle 27 extending into the sealing cover 10 and cleaning the utility knife is provided on the pipe 26; The sliding sleeve in the pipe 26 is provided with a piston 28 for pressurizing water, and the sliding sleeve in the pipe 26 is provided with a pressure rod connected to the piston 28, and a pressure plate 29 is fixedly installed on the pressure rod, and a spring 30 matching the pressure rod is welded between the pressure plate 29 and the pipe 26; A crossbar is fixedly mounted on the sealing cover 10, and a motor 31 is fixedly mounted on the crossbar. A rotating shaft 32 is fixedly connected to the output end of the motor 31, and an eccentric wheel 33 that movably contacts the two pressure plates 29 is fixedly mounted on the rotating shaft 32. When the processing of the utility knife is completed, the output end of the motor 31 drives the rotating shaft 32 and the eccentric wheel 33 to rotate. The eccentric wheel 33 can intermittently pressurize the two pressure plates 29 during rotation. The pressure plates 29 pressurize the water in the piston 28 through the pressure rod, so that the water is sprayed out through the nozzle 27 and cleans the utility knife, and the water and debris fall into the collection box 7. The mesh plate 8 can intercept the debris, and the filtered water can be recycled. It should be noted that the specific models and specifications of the cylinder 9, motor 1 11, motor 2 12, light sensor 15, lamp body 16, motor 3 31, and piston 28 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0020] The present invention can be explained by the following operation mode: Place multiple utility knives on the positioning table 3 in sequence, and apply pressure to the positioning table 3 so that the positioning table 3 drives the utility knives to move into the bracket 1; The handle is pulled, and the handle drives the positioning rod 6 to penetrate the positioning platform 3 and extend into the bracket 1; The output end of the cylinder 9 is extended and retracted to drive the sealing cover 10 to move downward, and the sealing cover 10 extends into the groove 5 after moving downward, thereby sealing the utility knife; The output end of the motor 2 12 drives the bidirectional screw 1 18 to rotate, and the bidirectional screw 1 18 drives the bidirectional screw 2 19 to rotate through the transmission belt 20. When the bidirectional screw 1 18 and the bidirectional screw 2 19 rotate, they drive the two nuts 2 21 to move toward or in the opposite direction. When the two nuts 21 move toward each other, they pull the connecting rod 24. The position difference generated when the connecting rod 24 deflects can apply pressure to the moving rod 23, so that the moving rod 23 drives the moving plate 25 to synchronously apply pressure to multiple utility knives. The output end of the motor 11 drives the screw rod 13 to rotate, and the screw rod 13 drives the nut 14 to move horizontally when rotating. When the nut 14 moves, it drives the lamp body 16 to correspond to one of the light sensors 15. When the light sensor 15 senses that the light value exceeds the specified threshold, it immediately sends a closing signal to the motor 11, so that the nut 14 drives the end 17 and the marking head 2 to stop moving. After the marking head 2 is powered on, it processes the utility knife; When one of the utility knives is finished processing, the marking head 2 returns to the initial position, the output end of the motor 11 drives the screw 13 to continue rotating, and the nut 14 drives the lamp body 16 to correspond to another light sensor 15 when moving, and the above steps are repeated, so that the marking head 2 can process multiple utility knives on the positioning table 3 in sequence; The output end of the motor 31 drives the rotating shaft 32 to rotate, and the rotating shaft 32 drives the eccentric wheel 33 to intermittently pressurize the two pressure plates 29. The pressure plate 29 pressurizes the water in the pipe 26 through the pressure rod to the piston 28. The spring 30 is stressed, so that the water in the pipe 26 is sprayed out through the nozzle 27 and cleans the utility knife, so that the iron filings and water on the utility knife fall into the collection box 7 through the hollow groove 4, and the mesh plate 8 in the collection box 7 can intercept the iron filings; When the processing of the utility knife is completed, the output end of the cylinder 9 drives the sealing cover 10 back to the initial position, and the utility knife on the positioning platform 3 is taken out.
