DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-5As shown, a die-cutting machine tool wear detection device comprises: a base 1, a die-cutting machine 11 is fixedly mounted on one side of the base 1, and a conveyor belt 2 is fixedly mounted on one side of the die-cutting machine 11; a wear detection mechanism 3, which is used to detect the wear of internal cutting parts when the die-cutting machine 11 is in use and is arranged inside the die-cutting machine 11; wherein the wear detection mechanism 3 comprises an electric push rod 31 fixedly mounted on the top of the die-cutting machine 11, a detection component 32 is arranged on one side of the electric push rod 31, and a replacement component 33 is arranged on one side of the detection component 32. Through the detection component 32, the wear of the tool 325 can be quickly detected after each use of the tool 325, so that the wear of the tool 325 can be better understood when the tool 325 should be replaced, so as to avoid affecting the cutting effect and product quality of the die-cutting machine 11 due to excessive wear of the tool 325. The replacement component 33 works synchronously with the detection component 32. Once it is detected that the wear of the tool 325 reaches the preset replacement standard, the tool 325 can be quickly replaced.

[0025] The detection component 32 includes a connecting plate 321 fixedly installed at the output end of the electric push rod 31, a rotating frame 322 is rotatably installed on one side of the connecting plate 321, a tool 325 is provided on one side of the rotating frame 322, a motor 323 is fixedly installed on one side of the connecting plate 321, and the output end of the motor 323 is fixedly connected to one side of the rotating frame 322, a positioning plate 326 is fixedly installed inside the die-cutting machine 11, a movable plate 327 is provided on one side of the positioning plate 326, a pressure sensor 3210 is fixedly installed on one side of the positioning plate 326, the output end of the pressure sensor 3210 is located between the movable plate 327 and the positioning plate 326 and contacts with one side of the movable plate 327, and one side of the positioning plate 326 is fixedly installed Equipped with a controller 3211, during detection, the rotating frame 322 can be rotated at a right angle by the motor 323, and the tool 325 can be rotated toward the movable plate 327. By making the tool 325 contact one side of the movable plate 327, the movable plate 327 moves toward the positioning plate 326 and touches the output end of the pressure sensor 3210 simultaneously. When the tool 325 contacts the movable plate 327 and applies pressure, the pressure sensor 3210 will detect the force change caused by the wear of the tool 325. This force change reflects the degree of wear of the tool 325. If the force is reduced to below a preset threshold, it means that the tool 325 has been worn to the extent that it needs to be replaced. At this time, the pressure sensor 3210 will transmit a signal to the controller 3211, and the controller 3211 will indicate the wear state of the tool 325 according to the received signal data.

[0026] like Figure 2 , Figure 3 and Figure 4As shown, the detection component 32 includes a rotating wheel 3212 arranged on one side of the movable plate 327, and both ends of the rotating wheel 3212 are rotatably connected to the moving rods 328, one end of the two moving rods 328 are fixedly connected to the movable plate 327, one end of the two moving rods 328 are extended from the movable plate 327 and are slidably connected to the positioning plate 326, and the outer side of the moving rod 328 is sleeved with a spring 329, and the spring 329 is located between the movable plate 327 and the positioning plate 326. When the tool 325 contacts, the rotating wheel 3212 can rotate and synchronously drive the two moving rods 328 to slide on one side of the positioning plate 326. When the moving rod 328 slides, the spring 329 is synchronously squeezed to deform, and the spring 329 is compressed when the tool 325 moves away. The movable plate 327 can be reset synchronously to facilitate the next detection. A plurality of contact wheels 3213 are fixedly installed on the surface of the rotating wheel 3212. The plurality of contact wheels 3213 are aligned with the tool 325. The plurality of contact wheels 3213 can be used to ensure that the tool 325 is in contact with the rotating wheel 3212 when the tool 325 contacts the aligned contact wheels 3213, thereby reducing the friction and wear of the tool 325 during wear detection and ensuring the accuracy of the detection and the service life of the tool 325. The contact wheel 3213 is designed to have a surface with a flexible material such as rubber, silicone, etc., which can gently contact the tool 325 and reduce potential damage to the edge of the tool 325. At the same time, it can effectively transmit motion and force, making the wear detection process smoother and more consistent.

[0027] like Figure 2 and Figure 5The cam 332 is a block 332 mounted on one side of the mounting frame 331 and two connection slots 333 are provided on both sides of the mounting frame 331. Two drive plates 334 are slidably mounted on one side of the mounting frame 331. The two drive plates 334 are respectively located on both sides of the mounting frame 331, and two plug rods 335 are fixedly mounted on adjacent sides of the two drive plates 334. The two plug rods 335 penetrate the mounting frame 331 and are engaged with the two connection slots 333 on the adjacent sides. When the tool 325 needs to be removed, the two drive plates 334 can be moved to synchronously drive the corresponding plug rods 335 to move, so that the two plug rods 335 on both sides move out of the corresponding connection slots 333, thereby releasing the limit on the connection block 332 and allowing the connection block 332 to slide out of the mounting frame 331. The tool 325 can be replaced very conveniently. The replacement component 33 also includes screws 336 rotatably installed on both sides of the installation frame 331. One end of the two screws 336 passes through the adjacent drive plates 334, and the screws 336 are threadedly connected to the adjacent drive plates 334. During installation, the drive plates 334 on both sides can be brought closer to each other by rotating the screws 336 on both sides, and the corresponding insertion rods 335 are clamped with the corresponding connecting grooves 333. This can make the tool 325 more stable when in use and prevent the insertion rod 335 from falling off the connecting groove 333. The insertion rod 335 is set to a hexagonal shape, and the shape of the connecting groove 333 is adapted to the shape of the insertion rod 335. When the insertion rod 335 is connected to the connecting groove 333, the hexagonal shape of the insertion rod 335 can increase the contact area, ensure the close fit between the insertion rod 335 and the connecting groove 333, thereby reducing sliding or rotation caused by vibration or torque during operation.

[0028] When the utility model is in use, the motor 323 can be used to rotate the rotating frame 322 at a right angle during detection, so that the tool 325 can be rotated toward the movable plate 327. By making the tool 325 contact one side of the movable plate 327, the movable plate 327 moves toward the positioning plate 326 and touches the output end of the pressure sensor 3210 synchronously. When the tool 325 contacts the movable plate 327 and applies pressure, the pressure sensor 3210 detects the force change caused by the wear of the tool 325. The force change reflects the degree of wear of the tool 325. If the force is reduced to When the pressure drops below a preset threshold, it indicates that the tool 325 has been worn to the extent that it needs to be replaced. At this time, the pressure sensor 3210 will transmit a signal to the controller 3211. The controller 3211 indicates the wear status of the tool 325 based on the received signal data. When the tool 325 contacts, the rotating wheel 3212 can be rotated and the two moving rods 328 can be driven to slide on one side of the positioning plate 326. When the moving rod 328 slides, the spring 329 is squeezed synchronously to deform. When the tool 325 moves away, the spring 329 is reset, and the movable plate 327 can be reset synchronously to facilitate the next time. The detection can be performed through multiple contact wheels 3213. When the tool 325 contacts the rotating wheel 3212, they all contact the contact wheels 3213 that are aligned with each other, thereby reducing the friction and wear of the tool 325 during wear detection, ensuring the accuracy of the detection and the service life of the tool 325. The contact wheel 3213 is designed to have a surface with a flexible material such as rubber, silicone, etc., which can gently contact the tool 325 to reduce potential damage to the edge of the tool 325. At the same time, it effectively transmits movement and force, making the wear detection process smoother and more consistent. When the tool 325 needs to be disassembled, it can be disassembled by moving the two drive plates. 334, the two driving plates 334 can synchronously drive the corresponding plug rods 335 to move, so that the two plug rods 335 on both sides are moved out of the corresponding connecting grooves 333, and the limit of the connecting block 332 can be released, so that the connecting block 332 can slide out of the installation frame 331, and the tool 325 can be replaced very conveniently. During installation, the driving plates 334 on both sides can be moved closer to each other by rotating the screws 336 on both sides, and the corresponding plug rods 335 are clamped with the corresponding connecting grooves 333, which can make the tool 325 more stable when in use and prevent the plug rods 335 from falling off from the connecting grooves 333.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
