[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figure 1-Figure 3 As shown, a continuous silicon nitride fiber filament cutting device includes a punch press 10, a feed conveyor belt a and a discharge conveyor belt b. Two blades are installed on the mold position of the punch press 10. The blades are used to cut the silicon nitride fiber filaments. The two blades are arranged up and down. The punch press 10 of this embodiment is a conventional punch press, and the feed conveyor belt a and the discharge conveyor belt b are both conventional crawler conveyor belts.

[0026] The feed conveyor belt a is located on one side of the punch press 10, and the discharge conveyor belt b is located on the other side of the punch press 10. The first and second rollers 21 and 22 arranged in an upper and lower arrangement are installed on the side of the feed conveyor belt a corresponding to the side close to the blade. The first roller 21 and the second roller 22 are transmission-connected, and one of the rollers is connected to the output end of a power mechanism. In this embodiment, the power mechanism is a conventional motor, and the first roller 21 and the second roller 22 are connected by a belt transmission. The silicon nitride fiber filaments to be cut are compacted by setting the first and second rollers 21 and 22, so that the silicon nitride fiber filaments will not be lifted or misaligned when the upper and lower blades are pressed down for cutting.

[0027] As a preferred embodiment of this embodiment, the outer surfaces of the first pressing roller 21 and the second pressing roller 22 are both provided with anti-slip patterns, and the anti-slip patterns include a plurality of grooves with diamond-shaped cross-sections. The anti-slip patterns are provided to increase the friction between the pressing rollers and the silicon nitride fiber filaments.

[0028] As a preferred embodiment of the present invention, the second pressing roller 22 is located above the first pressing roller 21, a photoelectric sensor block 31 is installed on one end of the first pressing roller 21, a counting photoelectric sensor 32 is installed on the side of the punching machine 10 corresponding to the side where the photoelectric sensor block 31 is installed, and the controller of the punching machine 10, the photoelectric sensor block 31 and the counting photoelectric sensor 32 are respectively connected to a controller for communication.

[0029] In this embodiment, the photoelectric sensor block 32, the counting photoelectric sensor 31 and the controller are all conventional electronic devices.

[0030] Every time the first pressure roller 21 rotates one circle, the photoelectric sensor sensing block 31 is sensed once by the counting photoelectric sensor 32, that is, a count is performed, and the counting photoelectric sensor 32 transmits the count to the controller, and the controller converts the number of sensing times into the wire feeding length. When the desired cutting length is reached, the controller controls the punch press 10 to cut; the cutting length is accurately controlled by the cooperation of the photoelectric sensor sensing block 32 and the counting photoelectric sensor 31, thereby improving the cutting accuracy.

[0031] As a preferred embodiment of this embodiment, it also includes a discharging workbench, and one end of the discharging conveyor belt b is arranged on the discharging workbench.

[0032] The discharging workbench includes a frame 41, a lifting platform 42, a first screw 43 and a second screw 44. One end of the first screw 43 is fixed on the lifting platform 42, the other end of the first screw 43 is fixedly connected to a first bevel gear 45, and the second screw 44 is rotatably connected to the frame 41. In this embodiment, a rolling bearing is installed on the frame 41, and the second screw 44 is connected to the rolling bearing. Other rotating parts can also be used for the rotatable connection of the second screw 44. The second screw 44 is fixedly connected to a second bevel gear 46 at one end corresponding to the end close to the first screw 43. The cross section of the first bevel gear 45 and the cross section of the second bevel gear 46 are arranged perpendicular to each other, and the first bevel gear 45 meshes with the second bevel gear 46. The discharging conveyor belt b is arranged on the lifting platform 42. Through the cooperation of the first bevel gear 45 and the second bevel gear 46, the height of the lifting platform 42 can be adjusted, so that in production, it can be adaptively adjusted according to the height of the user, which conforms to ergonomic technology and avoids the user from bending over repeatedly to pick up the cut tow.

[0033] A handle 47 is fixedly connected to the end of the second screw rod 44 corresponding to the end away from the second bevel gear 46 , and the handle 47 is provided to facilitate the rotation of the second screw rod 44 .

[0034] At least two guide shafts 48 are fixed on the lower end surface of the lifting platform 42, and through holes are respectively opened on the frame 41 corresponding to the lower sides of each guide shaft 48. The guide shafts 48 are inserted into the through holes one by one to play a guiding role.

[0035] At least three universal wheels 49 are installed on the lower end surface of the frame 41 to facilitate the movement of the frame 41.

[0036] The working principle of the cutting device is as follows: the silicon nitride fiber filaments are transported from the feed conveyor belt a to the punch press 10. When the transported length reaches the preset length to be cut, the controller controls the punch press 10 to cut, and the cut silicon nitride fiber filaments are transported to the discharge workbench by the discharge conveyor belt b.

[0037] In summary, the cutting equipment can accurately cut silicon nitride fiber filaments into segments according to production requirements, use the punch 10 to apply pressure to cut the silicon nitride fiber filaments, and then the cut silicon nitride fiber filaments are transported to the next workstation by the discharge conveyor belt, effectively improving the efficiency and accuracy of silicon nitride fiber filament cutting.
