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.

[0032] Example 1 A preferred embodiment of a filtering and screening device for high-performance fibers and composite materials provided by the present invention is as follows: Figures 1 to 7 As shown: A filtering and screening device for high-performance fibers and composite materials, comprising: Box 1; The top and bottom surfaces of the box body 1 are hollowed out, a rectangular opening 7 is provided on the front of the box body 1, a rectangular groove 8 is provided on the top of the inner wall of the rectangular opening 7 and the bottom of the inner wall, and a support frame 2 is fixedly installed at the bottom of the box body 1. The number of the support frames 2 is two, and the two support frames 2 are distributed on both sides with the midline of the front of the box body 1 as the axis of symmetry. The two installed support frames 2 can support the box body 1 to prevent the box body 1 from directly contacting the ground; A feed hopper 4 is arranged above the box body 1 and is used for feeding and processing; Among them, a protective cover 3 is fixedly installed on the side of the feed hopper 4, and the protective cover 3 is fixedly installed on the top of the box body 1. A support cover 5 is fixedly installed on the bottom surface of the feed hopper 4, and the support cover 5 is fixedly installed on the top of the box body 1. The protective cover 3 and the support cover 5 can protect the internal structure of the box body 1 and can also provide a stable support for the feed hopper 4. A working assembly 9 is arranged inside the box 1; Among them, the working component 9 includes a fork portion 91 installed in the box body 1, and the fork portion 91 is respectively connected to a pushing portion 92 and a screening portion 93. The pushing portion 92 is arranged above the fork portion 91, and the screening portion 93 is arranged below the fork portion 91, and the screening portion 93 and the box body 1 are slidingly arranged.

[0033] The fork portion 91 includes: Motor 911 is arranged on the right side of the box body 1; The first shaft 912 is fixedly mounted on the output end of the motor 911; The end of the first shaft 912 away from the motor 911 movably passes through the side of the box body 1 and extends into the box body 1; The fork body 917 is fixedly mounted on the left end of the first shaft 912; Among them, the fork body 917 is made of rubber material, and the number of the fork bodies 917 is three. The other two fork bodies 917 are fixedly installed on the second shaft 916. The right end of the second shaft 916 is rotatably connected to the inner wall of the box body 1 through a bearing. The outer wall of the second shaft 916 is fixedly installed with a second gear 915, and the second gear 915 is meshed with a first gear 913. The first gear 913 is fixedly installed on the outer wall of the first shaft 912.

[0034] In the specific implementation process, the motor 911 is started before the material enters. The first shaft 912 can be rotated by the action of the motor 911. The first shaft 912 can be rotated by the rotation of the first shaft 912. The first gear 913 and the fork body 917 installed on the outer wall of the first shaft 912 can be rotated. The second gear 915 can be rotated by the rotation of the first gear 913. The second shaft 916 can be rotated by the rotation of the second gear 915. Finally, the three fork bodies 917 can be rotated. The three fork bodies 917 can be rotated to separate the materials. The materials that are still stuck together after being processed by the pushing part 92 can be separated again, which is convenient for the subsequent screening work.

[0035] In this embodiment, a mounting plate 6 is fixedly installed on the lower surface of the motor 911, and the mounting plate 6 is fixedly installed on the side of the box body 1. The installed mounting plate 6 can play a role in fixing the motor 911 to prevent the motor 911 from being located in a suspended position, thereby affecting the normal operation of the motor 911 itself.

[0036] Furthermore, a block body 918 is fixedly installed on the inner surface of the fork body 917, and the block body 918 is movably connected to the lever 9121 through a pin 919. A first spring 9120 is arranged between the block body 918 and the lever 9121, and one end of the first spring 9120 is fixedly installed on one surface of the block body 918, and the end of the first spring 9120 away from the block body 918 is fixedly installed on one surface of the lever 9121.

[0037] In the specific implementation process, the connecting block 918 can be rotated under the action of the rotation of the fork body 917, and the lever 9121 can be rotated together under the setting of the pin 919. Then, the vibration of the lever 9121 can be achieved under the action of the first spring 9120, so that the lever 9121 can rotate and vibrate at the same time, thereby enhancing the effect of moving the material.

[0038] Example 2 Based on Example 1, a preferred embodiment of a filtering and screening device for high-performance fibers and composite materials provided by the present invention is as follows: Figures 1 to 7 As shown: The screening unit 93 includes: The screen frame 934 is disposed below the fork body 917, and the inner wall of the screen frame 934 is in contact with the right end of the fork body 917; Among them, an auxiliary plate 935 is fixedly installed on the surface of the screen frame 934, and the auxiliary plate 935 is slidably arranged with the slide groove 8. A third spring 936 is fixedly installed on the side of the auxiliary plate 935, and one end of the third spring 936 away from the auxiliary plate 935 is fixedly installed with the inner wall of the slide groove 8; The tapered column 931 is fixedly mounted on the side of the fork body 917; Among them, a limiting ring 932 is fixedly installed on the outer wall of the conical column 931, and a second steel wire rope 933 is arranged between the conical column 931 and the screen frame 934, one end of the second steel wire rope 933 is fixedly installed on the lower surface of the conical column 931, and the other end of the second steel wire rope 933 is fixedly installed on the side of the screen frame 934.

[0039] In the specific implementation process, the rotation of the fork body 917 can realize the rotation of the conical column 931, and the second steel wire rope 933 can be wound through the rotation of the conical column 931. Due to the cone surface of the conical column 931 and the setting of the limit ring 932, the second steel wire rope 933 is only temporarily wound around the outer wall of the conical column 931 and then quickly falls off. Due to the setting of the auxiliary plate 935 and the third spring 936, the reciprocating movement of the screen frame 934 can be realized under the short winding of the second steel wire rope 935. The fork body 91 is moved and vibrated to realize screening of the material processed by the fork portion 91. Since the right end of the fork body 917 is in contact with the inner wall of the screen frame 934, the fork body 917 can be squeezed when the screen frame 934 first moves to the left to deform the fork body 917. Then, the fork body 917 can be opened and contracted during the reciprocating process of the screen frame 934. During the opening and contraction process of the fork body 917, the force for blasting the material can be increased, thereby strengthening the blasting process for the materials that are stuck together.

[0040] In this embodiment, the height of the auxiliary plate 935 is smaller than the distance between the two slide grooves 8. Since the second steel wire rope 933 is in an inclined position, a slight inclined movement of the auxiliary plate 935 can be achieved during the brief winding of the second steel wire rope 933. The inclined reciprocating vibration of the screen frame 934 can be achieved through the slight inclined movement, thereby avoiding blockage of the screen frame 934 and affecting the subsequent screening work.

[0041] Example 3 Based on Examples 1 and 2, a preferred embodiment of a filtering and screening device for high-performance fibers and composite materials provided by the present invention is as follows: Figures 1 to 7 As shown: The pushing portion 92 includes: The mounting rod 922 is slidably disposed in the second slide groove 10 provided on the inner wall of the feed hopper 4, and a second spring 924 is fixedly mounted on the inner wall of the second slide groove 10, and one end of the second spring 924 is fixedly mounted on the surface of the mounting rod 922; A push rod 923 is fixedly mounted on the bottom surface of the mounting rod 922; There are multiple push rods 923, and the multiple push rods 923 are evenly spaced and distributed on the bottom surface of the mounting rod 922; The first steel wire rope 921 is fixedly mounted on one side of the mounting rod 922 , and one end of the first steel wire rope 921 is fixedly mounted on the surface of the conical column 931 .

[0042] In the specific implementation process, under the action of the rotation of the conical column 931 and the cooperation of the limit ring 932, the first steel wire rope 921 can be briefly wrapped around the conical column 931 and then quickly fall off the conical column 931. Due to the provision of the second spring 924, the mounting rod 922 can be reciprocated, and the reciprocating movement of the mounting rod 922 can be achieved. The push rod 923 can be reciprocated, and the reciprocating movement of the push rod 923 can be used to push the newly entered material, which facilitates the fork portion 91 to better handle the materials that are bonded together.

[0043] In this embodiment, the first steel wire rope 921 is sleeved with an auxiliary ring 925, and the auxiliary ring 925 is fixedly installed on the lower surface of the protective cover 3. The installed auxiliary ring 925 can make the first steel wire rope 921 have a spatial suspended position to avoid direct contact with the fork body 917 and affect the work.
