[0002] Thermoplastic polyurethane, abbreviated as TPU, is a multifunctional thermoplastic polymer with elastomeric properties. It has high toughness, high strength, and excellent tensile strength. Under the action of a long-term load, the strain curve has a small decline, and it is suitable for working in a harsh environment with a long-term load. During the processing of TPU materials, it is often necessary to cut the TPU materials into circular thin slices, and a circular TPU production cutter is required for cutting the TPU materials during the cutting process.

[0003] The existing circular TPU production cutters are widely used, but the sharpness of the blades will decline after being used for too long, and the blades need to be replaced. The existing blades are usually installed with screws, and the installation and disassembly of the screws are relatively troublesome. Moreover, after the circular blade cuts the material, the material is easy to get stuck inside the blade and is not easy to take out, and it is necessary to manually take out the material stuck inside the blade. Therefore, a circular TPU production cutter is proposed for the above problems. Content of the Utility Model

[0021] Please refer to Figures 1-3 , the present utility model provides a technical solution:

[0022] A circular TPU production cutting knife includes a mounting rod 1. The bottom end of the mounting rod 1 is fixedly connected to a horizontally arranged connecting plate 2. One end of the connecting plate 2 is fixedly connected to a mounting seat 3 located outside the mounting rod 1. A groove 4 is opened at the bottom end of the mounting seat 3. A through groove 5 communicating with the groove 4 is opened on the outside of the mounting seat 3. A positioning component 6 is arranged on one side of the through groove 5. An annular blade 7 closely fitting with the inner side of the groove 4 is arranged inside the groove 4. A fixing block 8 located inside the through groove 5 is fixedly connected to the outside of the annular blade 7. A second magnet 9 is fixedly connected to one side of the fixing block 8. A slot 10 penetrating the fixing block 8 and the second magnet 9 is opened inside the fixing block 8 and the second magnet 9.

[0023] The positioning component 6 includes a sliding frame 61 fixedly connected to the outside of the mounting base 3. A plug pin 62 is slidably connected to the inside of the sliding frame 61. One end of the plug pin 62 is fixedly connected to a baffle 63. A first magnet 64 is fixedly connected to the outside of the plug pin 62. The setting of the positioning component 6 makes the installation and disassembly of the annular blade 7 more convenient. The number of connecting plates 2 is multiple, and the connecting plates 2 are evenly distributed inside the mounting base 3. The number of through grooves 5 is multiple, and the through grooves 5 are evenly distributed outside the mounting base 3. The connection mode between the plug pin 62 and the slot 10 is a snap connection. The shapes and sizes of the first magnet 64 and the second magnet 9 are the same. The settings of the first magnet 64 and the second magnet 9 can make the connection between the plug pin 62 and the slot 10 more firm. A vertically arranged limiting rod 11 that penetrates the connecting plate 2 is slidably connected inside the connecting plate 2. Limiting plates 12 fixedly connected to the upper and lower ends of the limiting rod 11 are symmetrically arranged at the upper and lower ends of the limiting rod 11. A limiting spring 13 is arranged outside the limiting rod 11. A connecting ring 14 is fixedly connected to the outside of the lower limiting plate 12. A bottom block 15 is fixedly connected to the bottom end of the lower limiting plate 12. The setting of the limiting spring 13 and its connecting components can prevent the TPU material from getting stuck inside the annular blade 7 and being unable to be taken out. The top end of the limiting spring 13 is fixedly connected to the bottom end of the connecting plate 2, and the bottom end of the limiting spring 13 is fixedly connected to the top end of the lower limiting plate 12.

[0024] Workflow: When the TPU material needs to be cut, first install the annular blade 7. Align the through groove 5 with the fixed block 8 and insert the annular blade 7 into the inner side of the groove 4 on the mounting base 3 until the outer side of the annular blade 7 is in close contact with the inner side of the groove 4. Align the slot 10 with the pin 62 horizontally. Then pull the baffle 63 to make the pin 62 slide inside the sliding frame 61. The first magnet 64 moves with the pin 62 until the pin 62 is inserted into the inner side of the slot 10 on the fixed block 8. At this time, the first magnet 64 is magnetically connected to the second magnet 9, and the annular blade 7 can be fixed inside the mounting base 3. The settings of the baffle 63 and the first magnet 64 can prevent the pin 62 from detaching from the sliding frame 61. When the annular blade 7 needs to be disassembled, pull the baffle 63 to make the pin 62 slide inside the sliding frame 61. The first magnet 64 moves with the pin 62 and detaches from the second magnet 9. Then the annular blade 7 can be pulled out and replaced with a new one. The setting of the positioning component 6 makes the installation and disassembly of the annular blade 7 more convenient. Next, install the device on the machine through the mounting rod 1. Place the TPU material at the bottom of the device and start the machine. The output end of the machine extends and drives the device to descend. The bottom block 15 first contacts the TPU material. The bottom block 15 is stressed and drives the limiting rod 11 to slide inside the connecting plate 2. The limiting spring 13 at the top of the limiting plate 12 on the connecting ring 14 is compressed under stress. When the annular blade 7 contacts the TPU material and cuts the TPU material, turn off the machine. The output end of the machine rises and drives the device to rise. At this time, the limiting spring 13 is no longer stressed and starts to reset. The reset of the limiting spring 13 drives the limiting rod 11 to slide inside the connecting plate 2. The bottom block 15 descends to eject the TPU material stuck in the annular blade 7, thus preventing the TPU material from being stuck inside the annular blade 7 and unable to be taken out.
