A first rotating shaft is fixedly connected to the right end of the roller body, and a transmission gear is fixedly connected to the outer surface of the first rotating shaft. The transmission gear is located on the outer side of the roller body. A cutter roller is sleeved on the outer surface of the roller body, and a limit ring is fixedly connected to the right end of the cutter roller. The inner cavity of the limit ring is sleeved with the outer surface of the groove, and an insertion rod is fixedly connected to the inner cavity of the limit ring. The outer surface of the insertion rod is inserted into the inner cavity of the insertion hole. A first locking ring is sleeved on the outer surface of the limit ring, and a locking device is fixedly connected to the upper end of the first locking ring. During the die-cutting process, the die-cutting roller can be easily replaced by separating the cutter from the roller body, which shortens the replacement time of the die-cutting roller, improves the processing efficiency of the die-cutting roller, and reduces production costs.

[0004] However, the aforementioned protective component with a protective mechanism requires manual adjustment, which is slow and can slow down the overall production pace.

[0005] To address the aforementioned issues, a die-cutting roller with a protective structure is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a die-cutting roller with a protective structure to solve the problems of existing die-cutting rollers with protective structures mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a die-cutting roller with a protective structure, comprising a mounting housing, a mounting assembly disposed between the mounting housings, and a protective assembly disposed on the outer layer of the mounting housing;

[0008] The protective assembly includes a side mounting plate welded to one side of the mounting housing. A first protective cover is provided on the outer side of the mounting housing, and a second protective cover is provided on the outer surface of the mounting housing. The second protective cover is located on the outer surface of the first protective cover and is slidably connected to the first protective cover.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example

[0026] like Figure 1 , 3As shown in Figures 4 and 5, the system includes a mounting housing 1, a mounting assembly 2 disposed between the mounting housings 1, and a protective assembly 3 disposed on the outer layer of the mounting housing 1. The protective assembly 3 includes a side mounting plate 301 welded to one side of the mounting housing 1, a first protective cover 302 disposed on the outer side of the mounting housing 1, and a second protective cover 303 disposed on the outer side of the mounting housing 1, with the second protective cover 303 disposed on the outer surface of the first protective cover 302 and slidably connected to the first protective cover 302. First sliding grooves 304 are provided at the upper center and lower center of the side mounting plate 301, and the first protective cover 302 and the second protective cover... Both sides of 303 are provided with connecting posts 305. The middle of the connecting posts 305 near the side mounting plate 301 is fixedly connected to the first slider 306, and the first slider 306 is slidably connected to the first slide groove 304. The protective component 3 also includes a second slide groove 307 opened on one side of the side mounting plate 301. The inner wall of the second slide groove 307 is slidably connected to the second slider 308. Two sets of connecting arms 309 are rotatably connected to one side of the second slider 308. The internal thread of the second slider 308 is connected to a threaded rod 310. A servo motor 311 is installed at one end of the connecting end of the threaded rod 310.

[0027] It should be noted that in this embodiment, the first protective cover 302 and the second protective cover 303 in the protective assembly 3 are both located outside the first cutter roller 204 and the second cutter roller 205, providing a preliminary protective barrier for the die-cutting roller. The first protective cover 302 and the second protective cover 303 are connected by connecting posts 305 on both sides. Among them, a first slider 306 is fixedly connected to the middle of the connecting post 305 near the side mounting plate 301. The first slider 306 is slidably connected to the first groove 304 opened on the side mounting plate 301, which allows the first protective cover 302 and the second protective cover 303 to slide along the direction of the first groove 304. The second protective cover 303 is set on the outer surface of the first protective cover 302, and the two are slidably connected, ensuring the flexibility and adjustability of the protective structure during movement. When maintenance of the die-cutting roller is required, the servo motor 311 is started, and the servo motor 311 drives... When the threaded rod 310 rotates, since the second slider 308 is threadedly connected to the threaded rod 310, the second slider 308 will slide along the second slide groove 307 when the threaded rod 310 rotates. Two sets of connecting arms 309 are rotatably connected to one side of the second slider 308, and the connecting post 305 near the side mounting plate 301 passes through the first slide groove 304. One side of the connecting post 305 is rotatably connected to the connecting arm 309. As the second slider 308 slides, the connecting arm 309 will push the connecting post 305, thereby causing the first protective cover 302 and the second protective cover 303 to slide and unfold along the first slide groove 304, thus exposing the die-cutting roller. When the operation is completed, the servo motor 311 is restarted and reversed. At this time, the second slider 308 will slide in the opposite direction, and the connecting arm 309 will cause the first protective cover 302 and the second protective cover 303 to retract and cover the outside of the die-cutting roller again, restoring the protective function of the die-cutting roller.

[0028] When the servo motor 311 is started, it drives the threaded rod 310 to rotate, which in turn drives the second slider 308 to slide along the second slide groove 307. This controls the expansion and contraction of the first protective cover 302 and the second protective cover 303. The servo motor 311 used here has a self-locking function, which is a mature technology. Its implementation principle is usually based on electromagnetic braking, mechanical braking, demagnetization retention or encoder feedback. Regardless of the specific principle used to implement self-locking, the servo motor 311 selected in this device can reliably maintain its current position when the motor stops running, avoiding accidental rotation of the motor due to device vibration, external interference or other factors. This ensures the stability of the protective component 3 and provides effective protection for the safe operation of the entire die-cutting roller device. Therefore, the specific implementation method of its self-locking is not described in detail here.

[0029] like Figure 1 , 2As shown, the mounting assembly 2 includes a roller body 201 installed between mounting housings 1. Multiple sets of limiting grooves 202 are opened on opposite sides of the mounting housings 1. A mounting tube 203 is slidably connected to the inner wall of the mounting housings 1. A first cutter roller 204 is provided on the outer side of the roller body 201, and a second cutter roller 205 is provided on the outer side of the roller body 201. The first cutter roller 204 and the second cutter roller 205 form a complete die-cutting roller. Both ends of the mounting tube 203 are threaded with mounting bolts 206.

[0030] It should be noted that, in this embodiment, in the initial state, the mounting tube 203 is located inside the mounting housing 1. Multiple sets of limiting grooves 202 are formed on opposite sides of the mounting housing 1, providing guidance for the subsequent sliding of the mounting tube 203. The roller body 201 is installed between the two mounting housings 1, providing a supporting foundation for the installation of the die-cutting roller. First, the first die-cutting roller 204 and the second die-cutting roller 205 are installed on the outside of the roller body 201, forming a complete die-cutting roller. Then, the mounting tube 203 begins to slide. Since the inner wall of the mounting tube 203 is slidably connected to the inner wall of the mounting housing 1, during the sliding process, the mounting bolts 206 at both ends of the mounting tube 203 will be in the limiting grooves 202. The inner sliding groove 202 guides and constrains the sliding path of the mounting tube 203, ensuring that the mounting tube 203 moves smoothly towards the first cutter roller 204 and the second cutter roller 205. After the mounting tube 203 slides to the appropriate position, its inner wall is slidably connected with the first cutter roller 204 and the second cutter roller 205. Finally, by rotating the mounting bolts 206 at both ends of the mounting tube 203, they are threadedly connected to the first cutter roller 204 and the second cutter roller 205 respectively. In this way, the first cutter roller 204, the second cutter roller 205 and the roller body 201 are firmly fixed on the mounting tube 203, completing the installation process of the mounting component 2.

[0031] The outer wall of the mounting tube 203 is slidably connected to the mounting housing 1, and the inner wall of the mounting tube 203 is slidably connected to the first cutter roller 204 and the second cutter roller 205 respectively. When the mounting tube 203 slides toward the first cutter roller 204 and the second cutter roller 205, when the mounting tube 203 slides to the edge of the mounting housing 1, the edge of the mounting housing 1 plays a limiting role on the mounting tube 203 to prevent the mounting tube 203 from sliding excessively and to ensure that it accurately reaches the predetermined installation position.

[0032] Working principle of this utility model:

[0033] Refer to the instruction manual appendix Figure 1-5In the initial state, the mounting tube 203 is located inside the mounting housing 1. Multiple sets of limiting grooves 202 are formed on opposite sides of the mounting housing 1, providing guidance for the subsequent sliding of the mounting tube 203. The roller body 201 is installed between the two mounting housings 1, providing a supporting base for the installation of the die-cutting roller pieces. First, the first die-cutting roller piece 204 and the second die-cutting roller piece 205 are installed on the outside of the roller body 201, forming a complete die-cutting roller. Then, the mounting tube 203 begins to slide. Because the inner wall of the mounting tube 203 is slidably connected to the inner wall of the mounting housing 1, during the sliding process, the mounting bolts 206 at both ends of the mounting tube 203 will slide synchronously within the limiting grooves 202. The limiting groove 202 guides and constrains the sliding path of the mounting tube 203, ensuring that the mounting tube 203 moves smoothly towards the first cutter roller 204 and the second cutter roller 205. After the mounting tube 203 slides to the appropriate position, its inner wall is slidably connected with the first cutter roller 204 and the second cutter roller 205. Finally, by rotating the mounting bolts 206 at both ends of the mounting tube 203, they are threadedly connected to the first cutter roller 204 and the second cutter roller 205 respectively. In this way, the first cutter roller 204, the second cutter roller 205 and the roller body 201 are firmly fixed on the mounting tube 203, completing the installation process of the mounting component 2.

[0034] When maintenance of the die-cutting roller is required, the servo motor 311 is started, which drives the threaded rod 310 to rotate. Since the second slider 308 is threadedly connected to the threaded rod 310, the second slider 308 will slide along the second slide groove 307 when the threaded rod 310 rotates. Two sets of connecting arms 309 are rotatably connected to one side of the second slider 308, and the connecting post 305 near the side mounting plate 301 passes through the first slide groove 304, and one side of the connecting post 305 is connected to the connecting arm 309. The connection is active. As the second slider 308 slides, the connecting arm 309 pushes the connecting post 305, which in turn causes the first protective cover 302 and the second protective cover 303 to slide and unfold along the first slide groove 304, thereby exposing the die-cutting roller. After the operation is completed, the servo motor 311 is restarted and reversed. At this time, the second slider 308 will slide in the opposite direction, and the connecting arm 309 will cause the first protective cover 302 and the second protective cover 303 to retract and cover the outside of the die-cutting roller again, restoring the protective function of the die-cutting roller.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
