[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1 - Figure 3 Example 1 illustrates an industrial cutter disassembly and replacement device, comprising a main body plate 1. A supporting straight plate 2 is fixedly connected to the top of the main body plate 1. Two sets of linear guide rails 3 are symmetrically fixedly connected to the bottom of the supporting straight plate 2. Positioning components 4 are symmetrically arranged at both ends of the linear guide rails 3. A transmission component 5 is rotatably connected to the bottom of the positioning component 4. Two sets of alignment locking mechanisms 6 are symmetrically rotatably connected within the transmission component 5. The two sets of alignment locking mechanisms 6 correspond to the two sets of linear guide rails 3 respectively. The assembly includes an L-shaped connecting plate 601, a slider 602, a connecting sleeve 603, and a locking block 604. The top of the L-shaped connecting plate 601 is fixedly connected to the slider 602. The bottom of the L-shaped connecting plate 601 is fixedly connected to the connecting sleeve 603 and the locking block 604 from top to bottom. The connecting sleeve 603 is fitted onto the transmission assembly 5. The bottom of the front side of the main body plate 1 is fixedly connected to the mounting base 7. The cutting blade body 8 is fitted and engaged in the groove at the bottom of the mounting base 7. Several fastening pins 9 are evenly spaced and matched in the mounting base 7.

[0026] Please see Figure 2 and Figure 3 The mounting base 7 in the figure corresponds to the mounting hole on the top of the cutter body 8 via the fastening pin 9, and is fixedly connected to the cutter body 8 via the fastening pin 9.

[0027] Furthermore, the slider 602 is slidably connected to the linear guide rail 3, and two locking blocks 604 are symmetrically arranged on the left and right sides of the cutter body 8. The locking block 604 has a locking groove 605 on the side closer to the cutter body 8, and the locking groove 605 is matched and engaged with the left and right ends of the cutter body 8.

[0028] In this embodiment, when the cutter body 8 needs to be installed or replaced according to cutting requirements, the cutter body 8 is first inserted into the groove at the bottom of the mounting base 7. Then, the transmission component 5 is activated. The rotation of the transmission component 5 drives the two sets of alignment and locking mechanisms 6 on both sides to move synchronously toward the cutter body 8. At this time, the slider 602 slides horizontally on the linear guide rail 3 until the locking groove 605 of the locking block 604 engages with the left and right ends of the cutter body 8. This process pushes the cutter body 8 to adjust, ensuring that the mounting holes on the cutter body 8 automatically and accurately align with the mounting holes on the mounting base 7. After the alignment is completed, the cutter body 8 is firmly fixed to the mounting base 7 by the fastening pin 9. This makes the replacement of the cutter quick and accurate, significantly improving production efficiency and cutting accuracy. It avoids the problem of poor matching between the cutter and the cutter holder caused by improper manual installation, thereby ensuring cutting quality. By achieving quick and accurate positioning and locking, the time required to replace the cutter body 8 is greatly reduced, further improving production efficiency.

[0029] It should be noted that the operator can easily replace the cutter by simply loosening the fastening pin 9, sliding the cutter body 8 along the linear guide rail 3 to the appropriate position, and then tightening the fastening pin 9 again. This simplifies the cutter replacement process and improves work efficiency.

[0030] Example 2

[0031] Please see Figure 4 and Figure 5 Example 2 is described below. This embodiment further illustrates Example 1. The positioning component 4 shown in the figure includes a connecting seat 401, a fixing plate 402, and a bearing 403. The fixing plate 402 is fixedly connected to the side of the connecting seat 401 near the corresponding linear guide rail 3. The top of the fixing plate 402 is fixedly connected to the bottom of the supporting straight plate 2. The bearing 403 is fixedly connected inside the connecting seat 401. The setting of the bearing 403 ensures the stability and accuracy of the positioning component 4 when rotating, thereby ensuring the positioning accuracy of the cutting blade body 8 during the replacement process.

[0032] Furthermore, the transmission assembly 5 includes a coupling 501, a transmission shaft 502, and a threaded groove 503. The left and right ends of the coupling 501 are matched and connected to the transmission shaft 502. The transmission shaft 502 is provided with a threaded groove 503, and the spiral directions of the threaded grooves 503 on the two transmission shafts 502 are opposite.

[0033] In this embodiment, a connecting sleeve 603 is fitted and threaded onto the outer wall of the drive shaft 502. The drive shaft 502 is rotatably connected to the bearing 403. The rotation of the drive shaft 502 is synchronously transmitted to the two drive shafts through the coupling 501. Since the spiral directions of the threaded grooves 503 are opposite, the drive shaft 502 can generate thrust in opposite directions when rotating, thereby realizing the synchronous and precise left and right movement of the positioning and locking mechanism 6, ensuring that the cutting blade body 8 can be accurately positioned and locked.

[0034] It should be noted that the transmission component 5 can achieve bidirectional synchronous transmission during operation, ensuring the synchronous action of the alignment locking mechanism 6, thereby improving the speed and accuracy of changing the cutter body 8.

[0035] Example 3

[0036] Please see Figure 3 and Figure 5 Example 3 is described below. This embodiment further illustrates Example 2. In the figure, a connecting sleeve 603 is fitted and threaded onto the outer wall of the drive shaft 502. The drive shaft 502 is rotatably connected to the bearing 403.

[0037] Furthermore, a mounting plate 10 is fixedly connected to the right side of the main body plate 1, and a servo motor 11 is fixedly mounted on the right side of the mounting plate 10. The output end of the servo motor 11 passes through the mounting plate 10 and is fixedly connected to the right end of the transmission shaft 502 on the right side.

[0038] In this embodiment, the servo motor 11 is powered on and drives the right drive shaft 502 to rotate. While the drive shaft 502 rotates, the coupling 501 transmits power to the left drive shaft 502 to achieve bidirectional synchronous transmission. Since the threaded grooves 503 on the drive shaft 502 have opposite spiral directions, when the drive shaft 502 rotates, the connecting sleeve 603 will move synchronously along the threaded grooves 503, thereby driving the alignment locking mechanism 6 to perform synchronous action. This not only improves the replacement speed of the cutter body 8, but also ensures the accuracy and stability during the replacement process.

[0039] It should be noted that the use of servo motor 11 improves the automation level of the entire device. Operators only need to control servo motor 11 to achieve automatic positioning and locking of the cutting body 8, which further improves the convenience of operation and the accuracy of cutting.
