[0028] Please see Figures 1-5 A glass fiber yarn cutting device includes a cutting table 1, on which two moving grooves 2 are provided. A bidirectional lead screw 3 is rotatably provided in the moving grooves 2. One end of each of the two bidirectional lead screws 3 passes through the cutting table 1 and is connected to a synchronous belt drive structure 4. A first motor 5 is provided on one side of the cutting table 1. The driving end of the first motor 5 extends into the moving grooves 2 and is fixedly connected to the bidirectional lead screw 3. Two moving frames 6 are threadedly connected to each of the two bidirectional lead screws 3. A first electric push rod 7 is provided on the moving frame 6. A lifting frame 8 is fixedly provided on the driving end of the first electric push rod 7. A flattening roller 9 is rotatably provided on the lifting frame 8. A rotating rod 10 is rotatably provided on the moving frame 6. A pressing frame 11 is fixedly provided on the rotating rod 10. One end of the rotating rod 10 passes through the moving frame 6 and is fixedly connected to a third motor 28 fixedly provided on one side of the moving frame 6.

[0029] In this embodiment, the glass fiber yarn to be cut is placed on the cutting table 1 and passes under the two flattening rollers 9. The first electric push rod 7 is activated, which drives the lifting frame 8 to move downward. The lifting frame 8 drives the flattening rollers 9 to move downward and contact the glass fiber yarn. The first motor 5 is activated, which drives one of the bidirectional lead screws 3 to rotate. The bidirectional lead screw 3 drives the other bidirectional lead screw 3 to rotate simultaneously through the synchronous belt drive structure 4. Since the bidirectional lead screw 3 has two threaded areas with opposite directions, the two moving frames 6 move away from the middle of the cutting table 1. The moving frames 6 drive the flattening rollers 9 to move and rotate, thereby flattening the glass fiber yarn. When the moving frames 6 move to the ends of both sides of the glass fiber yarn, the second motor 12 is activated, which drives the rotating rod 10 to rotate. The rotating rod 10 drives the pressing frame 11 to rotate, so that the pressing frame 11 presses the ends of the glass fiber yarn, thereby fixing it.

[0030] Please see Figures 1-5As one embodiment of the installation of the cutting blade 16: a movable frame 13 is movably provided on the outer side of the cutting table 1, and a mounting shell 14 is movably provided on the movable frame 13. A blade holder 15 is installed inside the mounting shell 14, and the cutting blade 16 is fixedly provided at the lower end of the blade holder 15. Multiple limiting rods 17 are fixedly provided inside the mounting shell 14, and the multiple limiting rods 17 are movably connected to the blade holder 15. Multiple limiting holes 18 that cooperate with the limiting rods 17 are provided on the blade holder 15. A screw 19 is rotatably provided inside the mounting shell 14. One end of the screw 19 passes through the mounting shell 14 and is fixedly provided with a handle 20. A fixing seat 21 is threadedly connected to the screw 19. A fixing plate 22 is fixedly provided at the lower end of the fixing seat 21. Multiple through holes 23 that cooperate with the limiting rods 17 are provided on the fixing plate 22.

[0031] Specifically, the blade holder 15 is moved to move the cutting blade 16, and the blade holder 15 is placed inside the mounting housing 14. Simultaneously, multiple limiting rods 17 are inserted into multiple limiting holes 18. The handle 20 is rotated, causing the screw 19 to rotate. Since the screw 19 is threadedly connected to the fixing base 21, the fixing base 21 moves the fixing plate 22. As the fixing plate 22 moves, one end of the limiting rod 17 is inserted into the through hole 23. Under the pressure of the fixing plate 22, the blade holder 15 is fixed into the mounting housing 14, thus installing the cutting blade 16. When the cutting blade 16 needs to be replaced, the reverse operation can be used.

[0032] Please see Figures 1-5 As one way to adjust the cutting position:

[0033] Guide rods 24 are fixedly provided on both sides of the cutting table 1. The guide rods 24 are slidably connected to the moving frame 13. A second electric push rod 25 is fixedly provided on the moving frame 13. The driving end of the second electric push rod 25 passes through the moving frame 13 and is fixedly connected to the mounting shell 14. A limiting groove 26 is provided at the lower end of the cutting table 1. A drive screw 27 is rotatably provided in the limiting groove 26. A third motor 28 is fixedly provided on one side of the cutting table 1. The driving end of the third motor 28 extends into the limiting groove 26 and is fixedly connected to the drive screw 27. A cutting seat 29 is threadedly connected to the drive screw 27. The lower end of the cutting seat 29 passes through the limiting groove 26 and is fixedly connected to the moving frame 13.

[0034] Specifically, the third motor 28 is activated as needed to cut the glass fiber yarn. The third motor 28 drives the drive screw 27 to rotate. Since the drive screw 27 is threadedly connected to the cutting seat 29, the cutting seat 29 moves along the limiting groove 26. The cutting seat 29 drives the moving frame 13 to move along the two guide rods 24. The moving frame 13 drives the second electric push rod 25, the mounting shell 14 and the installed cutting blade 16 to move, thereby adjusting the position of the cutting blade 16. The second electric push rod 25 is activated, and the second electric push rod 25 drives the mounting shell 14 and the cutting blade 16 to move downward, thereby cutting the glass fiber yarn.

[0035] In summary, when using the overall equipment:

[0036] When the cutting blade 16 needs to be installed, move the blade holder 15 to move the cutting blade 16 and place the blade holder 15 into the mounting housing 14. Simultaneously, insert multiple limiting rods 17 into multiple limiting holes 18. Turn the handle 20, which drives the screw 19 to rotate. Since the screw 19 is threadedly connected to the fixing base 21, the fixing base 21 moves the fixing plate 22. As the fixing plate 22 moves, one end of the limiting rod 17 inserts into the through hole 23. Under the pressure of the fixing plate 22, the blade holder 15 is fixed into the mounting housing 14, thus installing the cutting blade 16. When the cutting blade 16 needs to be replaced, the reverse operation can be used.

[0037] When it is necessary to flatten and fix the glass fiber yarn, the glass fiber yarn to be cut is placed on the cutting table 1 and passes under the two flattening rollers 9. The first electric push rod 7 is activated, which drives the lifting frame 8 to move downward. The lifting frame 8 drives the flattening rollers 9 to move downward and contact the glass fiber yarn. The first motor 5 is activated, which drives one of the bidirectional lead screws 3 to rotate. The bidirectional lead screw 3 drives the other bidirectional lead screw 3 to rotate simultaneously through the synchronous belt drive structure 4. Since the bidirectional lead screw 3 has two threaded areas with opposite directions, the two moving frames 6 move away from the middle of the cutting table 1. The moving frames 6 drive the flattening rollers 9 to move and rotate, thereby flattening the glass fiber yarn. When the moving frames 6 move to the ends of both sides of the glass fiber yarn, the second motor 12 is activated. The second motor 12 drives the rotating rod 10 to rotate. The rotating rod 10 drives the pressing frame 11 to rotate, so that the pressing frame 11 presses the ends of the glass fiber yarn, thereby fixing it. Synchronous belt drive structure 4 is a meshing type belt drive, which relies on the meshing of the teeth on the drive belt and the pulley for transmission. In this type of transmission, there is no relative slippage between the pulley and the drive belt, which can ensure a strict transmission ratio. Since the synchronous belt drive structure is existing technology, its specific structure and working principle will not be described in detail here.

[0038] When the position of the cutting blade 16 needs to be adjusted, the third motor 28 is activated according to the required cutting position of the glass fiber yarn. The third motor 28 drives the drive screw 27 to rotate. Since the drive screw 27 is threadedly connected to the cutting seat 29, the cutting seat 29 moves along the limiting groove 26. The cutting seat 29 drives the moving frame 13 to move along the two guide rods 24. The moving frame 13 drives the second electric push rod 25, the mounting shell 14 and the installed cutting blade 16 to move, thereby adjusting the position of the cutting blade 16. The second electric push rod 25 is activated, and the second electric push rod 25 drives the mounting shell 14 and the cutting blade 16 to move downward, thereby cutting the glass fiber yarn.

[0039] A controller is provided on one side of the cutting table 1. All electrical equipment on the entire device is controlled by the controller. Since the equipment matched with the controller is a common device, its control principle and wiring connection are existing, well-known and mature technologies. Therefore, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0040] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
