[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Example:
[0030] like Figure 1-10 As shown, this embodiment proposes a vibrating screening and conveying device for differentiated fiber raw materials, including a vibrating housing 10, and a vibrating plate 20 is provided inside the vibrating housing 10;
[0031] An adjustment plate 30 is provided at the bottom end of the vibrating plate 20. The vibrating plate 20 is provided with multiple sets of first screening holes 21, and the adjustment plate 30 is provided with multiple sets of second screening holes 33. The positions and sizes of the multiple sets of first screening holes 21 and multiple sets of second screening holes 33 are matched. An adjustment component 40 is provided on the vibrating plate 20. The adjustment component 40 cooperates with the adjustment plate 30 to make the adjustment plate 30 move along the long side of the vibrating plate 20, thereby controlling the misalignment of the first screening holes 21 and the second screening holes 33.
[0032] In this embodiment, when the differentiated fiber raw materials are vibrated and screened, the initial alignment (complete overlap) of the first screening hole 21 on the surface of the vibrating plate 20 and the second screening hole 33 on the surface of the adjusting plate 30 is observed in the stopped state. At the same time, the required effective screen hole diameter is set according to the size and density characteristics of the target fiber raw materials. Then, the adjusting component 40 is started to drive the adjusting plate 30 to move along the long side of the vibrating plate 20, so that the first screening hole 21 and the second screening hole 33 are misaligned to form a screening channel. The screening channel matches the previously confirmed effective screen hole diameter, so that the differentiated fiber raw materials that meet the effective screen hole diameter can fall, and those that do not meet the diameter are transmitted to the next process through the vibrating plate 20.
[0033] By adjusting the component 40 to drive the adjustment plate 30 to translate relative to the vibrating plate 20, the misalignment between the first screening hole 21 and the second screening hole 33 is precisely controlled, forming an adjustable and effective sieve channel. This structure allows the screening aperture to be dynamically matched according to the size and density characteristics of different fiber raw materials, such as (the misalignment is set when the machine is stopped in the embodiment). This breaks through the limitations of traditional fixed screens, significantly improves the adaptability of the equipment to materials of different specifications, and realizes the precise grading and screening of differentiated fiber raw materials.
[0034] Specifically, the bottom end of the vibrating plate 20 is provided with four sets of fixing blocks 22, and the four sets of fixing blocks 22 are respectively located at the four corners of the vibrating plate 20.
[0035] The adjustment assembly 40 includes two sets of screws 41, which are symmetrically arranged and rotatably connected between two sets of fixed blocks 22.
[0036] In this embodiment, when the position of the adjustment plate 30 needs to be adjusted, the rotation of the screw 41 on the fixed block 22 can facilitate the adjustment of the position of the adjustment plate 30.
[0037] Specifically, hexagonal actuating blocks 42 are provided on both end faces of the screw 41, and the hexagonal actuating blocks 42 are fixedly connected to the screw 41.
[0038] In this embodiment, the hexagonal toggle block 42 facilitates the rotation of the screw 41, enabling efficient adjustment.
[0039] Specifically, two sets of mounting plates 31 are symmetrically arranged on the adjustment plate 30. The mounting plates 31 are provided with threaded holes 32. The two sets of screws 41 are respectively arranged in the two sets of threaded holes 32, and the screws 41 are threadedly engaged with the threaded holes 32.
[0040] In this embodiment, when the adjusting plate 30 is displaced along the long side of the vibrating plate 20, the rotation of the screw 41, combined with the threaded engagement between the screw 41 and the threaded hole 32, allows the adjusting plate 30 to be displaced and adjusted along the long side of the vibrating plate 20.
[0041] Specifically, a limiting block 50 is provided on the screw 41, and the limiting block 50 is provided with a limiting hole 51. The screw 41 is slidably disposed in the limiting hole 51, and the limiting block 50 is in contact with but not connected to the bottom end face of the vibrating plate 20.
[0042] Specifically, a limiting groove 52 is provided on the limiting block 50, and the limiting groove 52 extends through to the limiting hole 51;
[0043] The limiting block 50 is also provided with two sets of limiting plates 55. The two sets of limiting plates 55 are symmetrically arranged on both sides of the limiting groove 52. A fastening bolt 53 is provided between the two sets of limiting plates 55. An anti-loosening nut 54 is threaded on the outer wall of the fastening bolt 53.
[0044] In this embodiment, after the displacement adjustment of the adjusting plate 30 is completed, the operator tightens the fastening bolt 53 and locks the anti-loosening nut 54. At this time, the limiting groove 52 undergoes elastic deformation under the radial pressure of the bolt, causing the inner wall of the limiting hole 51 to form a clamping effect with the outer diameter of the adjusting screw 41. The limiting block 50 maintains non-fixed contact with the bottom surface of the vibrating plate 20 through the bottom plane. While achieving radial constraint on the adjusting screw 41, the friction torque of the contact surface effectively prevents axial displacement generated during the adjustment process, thereby ensuring the positional stability after the screen hole misalignment is adjusted.
[0045] Specifically, a fixing plate 60 is provided on the fixing block 22, and a fixing hole 61 is provided on the fixing plate 60. A bolt for connecting to the vibrating housing 10 is provided in the fixing hole 61.
[0046] In this embodiment, the fixed plate 60 facilitates the connection between the vibrating plate 20 and the vibrating housing 10;
[0047] Of course, the vibrating housing 10 is existing technology and will not be described in detail here.
[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
