Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of screening, in particular to a screening device for fiber mixtures. Background Art
[0002] During the production process of powder materials, fibers are inevitably introduced. Generally, the fiber length is about 500 - 2000 microns, and the diameter ranges from a few microns to dozens of microns. However, the existing screening systems used in the production of powder materials cannot effectively remove fibers with diameters smaller than the particle size of the powder. Because in the conventional sieving process, in order to improve production efficiency, a vertical vibration wave is applied to the sieve mesh. Under the vertical vibration, the fibers bounce on the surface of the sieve mesh, and the orientation of the fibers changes from horizontal to vertical. When the diameter of the fiber is smaller than the mesh hole of the sieve mesh, the fiber will pass through the sieve mesh, resulting in incomplete fiber screening and foreign matter contamination of the product. Summary of the Utility Model
[0003] To solve the technical problems in the background art, the utility model proposes a screening device for fiber mixtures.
[0004] A screening device for fiber mixtures proposed by the utility model includes: a housing with a first feed inlet at the top and a discharge outlet at the bottom; a first sieve mesh installed inside the housing, located between the first feed inlet and the discharge outlet; a plate body installed inside the housing and directly below the first feed inlet, located above the first sieve mesh, and a gap is reserved between the plate body and the inner wall of the housing to enable the fiber mixture on the plate body to laterally separate from the plate body.
[0005] Preferably, the center of the first vertical projection of the plate body on the horizontal plane coincides with the center of the second vertical projection of the first feed inlet on the horizontal plane.
[0006] Preferably, it further includes a base and a driving component. The housing is movably installed on the base, and the driving component is drivingly connected to the housing. The area of the first vertical projection is larger than the area of the second vertical projection, so that when the driving component drives the housing to move horizontally back and forth relative to the base, the fiber mixture falling into the housing from the first feed inlet first lands on the plate body.
[0007] Preferably, the driving component specifically includes: a motor, a first connecting rod, a second connecting rod, a slider, a first shaft, and a second shaft; the base is provided with a first horizontal chute and a second horizontal chute. The housing is assembled in the first horizontal chute, the slider is assembled in the second horizontal chute, one end of the slider is fixed to the housing, the other end of the slider is hinged to the first connecting rod through the first shaft, the other end of the first connecting rod is hinged to the second connecting rod through the second shaft, and the other end of the second connecting rod is fixed to the driving shaft of the motor and can be driven by the motor to rotate. The first shaft, the second shaft, and the driving shaft are arranged in parallel and the axial directions of the three are perpendicular to the extending directions of the first horizontal chute and the second horizontal chute.
[0008] Preferably, the distance between the plate body and the first feed inlet is greater than the distance between the plate body and the first screen.
[0009] Preferably, it includes a second screen, the second screen is installed in the housing and arranged in parallel at intervals below the first screen, and the mesh number of the first screen is smaller than that of the second screen.

The fiber mixture is input into the first feed inlet through the external conveying pipeline. The fiber mixture directly falls on the plate body. The housing is driven to move horizontally back and forth. The fiber mixture on the plate body laterally detaches from the plate body through the gap and falls on the first screen. Along with the horizontal back-and-forth movement of the housing, the fibers in the fiber mixture remain on the first screen, and the powder materials in the fiber mixture pass through the screen holes of the first screen and are discharged through the discharge outlet, thereby realizing the screening of the fibers and the powder materials in the fiber mixture. In the present invention, through the arrangement of the plate body, it is possible to prevent the fibers in the fiber mixture falling on the first screen from jumping in the vertical direction, so that the fibers fall horizontally on the first screen, reducing the probability of the fibers passing through the screen holes, thereby improving the screening effect of the fibers and the powder materials.

[0017] Referring to Figure 1-2, a fiber mixture screening device proposed by the present utility model includes: a housing 1 with a first feed inlet 11 at the top and a discharge outlet 12 at the bottom; a first screen 2 installed inside the housing 1, and the first screen 2 is located between the first feed inlet 11 and the discharge outlet 12; a plate body 3 installed inside the housing 1 and directly below the first feed inlet 11, the plate body 3 is located above the first screen 2, and a gap is reserved between the plate body 3 and the inner wall of the housing 1 to enable the fiber mixture on the plate body 3 to horizontally separate from the plate body 3.
[0018] In the specific working process of the fiber mixture screening device of this embodiment, the output port of the external conveying pipeline (hose) is hermetically connected to the first feed inlet 11, and the fiber mixture is input into the first feed inlet 11 through the external conveying pipeline. The fiber mixture directly falls on the plate body 3. The housing 1 is driven to move horizontally back and forth. The fiber mixture on the plate body 3 horizontally separates from the plate body 3 through the gap and falls on the first screen 2. Along with the horizontal back-and-forth movement of the housing 1, the fibers in the fiber mixture remain on the first screen 2, and the powder material in the fiber mixture passes through the screen holes of the first screen 2 and is discharged from the discharge outlet 12, thereby realizing the screening of the fibers and the powder material in the fiber mixture. In the present utility model, through the setting of the plate body 3, it is possible to prevent the fibers in the fiber mixture falling on the first screen 2 from jumping in the vertical direction, so that the fibers fall horizontally on the first screen 2, reducing the probability of the fibers passing through the screen holes, thereby improving the screening effect of the fibers and the powder material.
[0019] Refer to Figure 3-4 , in the fiber mixture screening device proposed in this embodiment, the center of the first vertical projection of the plate body 3 on the horizontal plane coincides with the center of the second vertical projection of the first feed inlet 11 on the horizontal plane. At the same time, it also includes a base 4 and a driving component 5. The housing 1 is movably installed on the base 4, and the driving component 5 is drivingly connected to the housing 1. The area of the first vertical projection is larger than the area of the second vertical projection, so that when the driving component 5 drives the housing 1 to move horizontally back and forth relative to the base 4, the fiber mixture falling into the housing 1 from the first feed inlet 11 first falls on the plate body 3. Thus, all the fiber mixtures falling into the housing 1 from the first feed inlet 11 can rely on the plate body 3 to prevent the fibers in the fiber mixture falling on the first screen 2 from jumping in the vertical direction, so that the fibers fall horizontally on the first screen 2, improving the screening effect of the fibers and the powder material.
[0020] In the fiber mixture screening device proposed in this embodiment, the driving assembly 5 specifically includes: a motor 51, a first connecting rod 52, a second connecting rod 53, a slider 54, a first shaft 55, and a second shaft 56; the base 4 is provided with a first horizontal chute 41 and a second horizontal chute 42, the outer shell 1 is assembled in the first horizontal chute 41, the slider 54 is assembled in the second horizontal chute 42, one end of the slider 54 is fixed to the outer shell 1, the other end of the slider 54 is hinged to the first connecting rod 52 through the first shaft 55, the other end of the first connecting rod 52 is hinged to the second connecting rod 53 through the second shaft 56, the other end of the second connecting rod 53 is fixed to the driving shaft 511 of the motor 51 and can be driven to rotate by the motor 51, the first shaft 55, the second shaft 56, and the driving shaft 511 are arranged in parallel and the axial directions of the three are perpendicular to the extending directions of the first horizontal chute 41 and the second horizontal chute 42. Thus, by driving the second connecting rod 53 to rotate by the motor 51, the second connecting rod 53 drives the first connecting rod 52 to move, the first connecting rod 52 drives the slider 54 to move horizontally back and forth in the second horizontal chute 42, so as to drive the outer shell 1 to move horizontally back and forth relative to the base 4. Furthermore, by driving the outer shell 1 to move horizontally back and forth, it is possible to further prevent the fibers in the fiber mixture falling on the first screen 2 from bouncing vertically, so that the fibers fall horizontally on the first screen 2, reducing the probability of the fibers passing through the screen holes, thereby improving the screening effect of the fibers and the powder material.
[0021] In the fiber mixture screening device proposed in this embodiment, the distance between the plate body 3 and the first feed port 11 is greater than the distance between the plate body 3 and the first screen 2. Thus, it is further ensured that the fiber mixture falling into the outer shell 1 from the first feed port 11 can all rely on the plate body 3, so as to prevent the fibers in the fiber mixture falling on the first screen 2 from bouncing vertically, so as to achieve the fibers falling horizontally on the first screen 2 and improve the screening effect of the fibers and the powder material.
[0022] In the fiber mixture screening device proposed in this embodiment, it includes a second screen 6, the second screen 6 is installed in the outer shell 1 and is arranged parallel and spaced below the first screen 2, and the mesh number of the first screen 2 is less than the mesh number of the second screen 6. Thus, through the coarse screening of the first screen 2 and then the fine screening of the second screen 6, it is convenient to further improve the screening effect of the fibers and the powder material.
[0023] In the fiber mixture screening device proposed in this embodiment, the outer shell 1 includes an outer shell body 13 and a cover body 14 detachably covering the top opening of the outer shell body 13, the cover body 14 is provided with a first feed port 11, and the bottom of the outer shell body 13 is provided with a discharge port 12; the first screen 2 and the second screen 6 are both detachably installed in the outer shell 1. Thus, it is convenient to remove the fibers remaining on the first screen 2 and / or the second screen 6 after screening by disassembling the cover body 14, the first screen 2, and / or the second screen 6.
[0024] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
