Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of vibrating fiber screening machines, and specifically relates to a vibrating fiber screening device. Background Technology
[0002] It is a screening device commonly used for cellulosic materials. Its working principle is to use a high-speed rotating vibrating motor to vibrate the material in the screen frame, so that the material is screened in the screen holes, thereby achieving the separation of materials of different particle sizes. However, when separating a large amount of material, when materials of different sizes pass through the screen, smaller materials may be stuck in the screen by larger materials. If the vibration cannot separate them, the opening will be blocked, reducing the screening speed. Utility Model Content

[0007] The working chamber a has multiple large-mesh screens a arranged at equal intervals inside, and the working chamber b has multiple large-mesh screens b arranged at equal intervals inside.

[0008] The inner walls of both the left and right ends of the working chamber a are fixedly connected to fixed blocks. The fixed blocks have limit grooves inside, and sliders are installed inside the limit grooves. A connecting rod is fixedly connected to the outer wall of the left end of the slider, and a clearing rod is fixedly connected to the outer wall of the upper end of the connecting rod to pass through and clear the mesh openings inside the large mesh screen a and the large mesh screen b.
[0009] Preferably, the front outer wall of the fixing block has an opening to limit the vertical movement of the connecting rod. The horizontal and vertical lengths of the opening are both less than the horizontal and vertical lengths of the limiting groove to limit the movement space of the slider.
[0010] Preferably, the lateral length and width of the unblocking rod are both smaller than the lateral length and width of the mesh openings inside the large mesh screen a and large mesh screen b, and the connecting rod and the unblocking rod are arranged in a honeycomb pattern.
[0011] Preferably, the center of the unblocking rod and the center of the mesh openings inside the large mesh screen a and large mesh screen b are on the same horizontal vertical line, and the lateral length of the slider is greater than the lateral length of the opening.

[0016] Compared with the prior art, the present invention provides a vibrating fiber screening device, which has the following beneficial effects:
[0017] By installing a clearing rod, connecting rod, slider, fixing block, and limiting groove, when the vibrating motor is working, the slider moves up and down within the groove in the fixing block, following the vibration amplitude. During this up-and-down movement, the clearing rod, which is smaller than the mesh width of large mesh screens a and b, is driven to clear the fibers blocking the large mesh screens a and b. This prevents fibers of inconsistent sizes from clogging the meshes of large mesh screens a and b, speeds up the screening process of large mesh screens a and b, reduces downtime during production, and ensures product quality and stability. This allows the fiber vibrating screen to perform screening work more stably and efficiently. Attached Figure Description

[0025] 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.
[0026] This utility model provides, for example Figure 1-3 The vibrating fiber screening device shown includes a working chamber a3 and a top cover 2 installed on the upper outer wall of the working chamber a3.
[0027] The upper outer wall of the top cover 2 is fixedly connected to the feed inlet 1, where fibers to be screened are previously added inside the working chamber a3;
[0028] A working compartment b4 is provided on the lower side of working compartment a3;
[0029] Multiple large-mesh screens a11 are equidistantly arranged inside working chamber a3, and multiple large-mesh screens b12 are equidistantly arranged inside working chamber b4. A vibration motor 7 is installed on the lower side of working chamber b4 to provide amplitude for working chambers a3 and b4 to shake. Working chambers a3 and b4 are assembled together. Then, the fiber to be screened is added into working chamber a3 through feed port 1. Then, the vibration motor 7 is powered on to generate high-frequency vibration amplitude into working chambers a3 and b4. During the vibration process, fibers smaller than the large-mesh screens a11 will move downward into working chamber b4 and be screened a second time through the large-mesh screens b12. At the same time, fibers smaller than the large-mesh screens b12 will continue to move downward and accumulate inside working chamber b4. After the work is completed, working chambers a3 and b4 are separated, and the screened fibers can be taken out.
[0030] Fixed blocks 16 are fixedly connected to the inner walls of both ends of the working chamber a3. The fixed blocks 16 have limiting grooves 17 inside, and sliders 18 are installed inside the limiting grooves 17. A connecting rod 19 is fixedly connected to the outer wall of the left end of the slider 18. A clearing rod 20 is fixedly connected to the outer wall of the upper end of the connecting rod 19 to pass through and clear the mesh openings inside the large mesh screens a11 and b12. During the vibration of the working chambers a3 and b4, the vibration amplitude will cause the slider 18 to move up and down in the limiting grooves 17 inside the fixed blocks 16. During the movement, the connecting rod 19 will move the clearing rod 20 upward to lift the fibers blocked inside the large mesh screens a11 and b12, thus preventing blockage.
[0031] like Figure 4 As shown, the front outer wall of the fixing block 16 has an opening 21 to limit the vertical movement of the connecting rod 19. The horizontal and vertical lengths of the opening 21 are both smaller than the horizontal and vertical lengths of the limiting groove 17 to limit the movement space of the slider 18.
[0032] The vertical movement distance of the slider 18 and the connecting rod 19 is limited by the opening 21 and the limiting groove 17 to avoid the situation where the position of the unblocking rod 20 is offset during the movement and cannot be accurately inserted into the internal mesh of the large mesh screen a11 and the large mesh screen b12.
[0033] like Figure 4 and Figure 5 As shown, the lateral length and width of the unblocking rod 20 are both smaller than the lateral length and width of the mesh openings inside the large mesh screen a11 and the large mesh screen b12, and the connecting rod 19 and the unblocking rod 20 are arranged in a honeycomb pattern.
[0034] This allows the unblocking rod 20 to be accurately inserted into the interior of the large-mesh screen a11 and the large-mesh screen b12, pushing out the fibers that are blocked inside. The honeycomb-shaped connecting rod 19 and the unblocking rod 20 can be adapted to the mesh density and position of the large-mesh screen a11 and the large-mesh screen b12 to calibrate the position of the unblocking rod 20, and can avoid breakage when moving up and down.
[0035] like Figure 4 and Figure 6 As shown, the center of the unblocking rod 20 and the center of the mesh openings inside the large mesh screens a11 and b12 are on the same horizontal vertical line, and the horizontal length of the slider 18 is greater than the horizontal length of the opening 21.
[0036] This allows the unblocking rod 20 to accurately penetrate the interior of the large mesh screen a11 and the large mesh screen b12. The lateral length of the slider 18 is greater than the lateral length of the opening 21, which can limit the position of the slider 18 and prevent the slider 18 from coming out of the limiting groove 17.
[0037] like Figure 1 and Figure 2 As shown, a base 6 is fixedly connected to the upper outer wall of the vibration motor 7, and a base plate 8 is fixedly connected to the lower outer wall of the working chamber b4 to store fibers inside the working chamber b4. Multiple shock-absorbing springs 5 are fixedly connected at equal intervals between the base plate 8 and the base 6 to reduce the shaking amplitude during vibration. Support blocks 14 are fixedly connected to the inner walls of the left and right ends of the working chambers a3 and b4, and located below the fixed frame 13, to limit the position of the large mesh screens a11 and b12. The fixed frame 13 is provided with a fixing screw 15 that is threadedly connected to the support block 14 to limit the position of the large mesh screens a11 and b12.
[0038] When the vibration motor 7 is working, it transmits the vibration amplitude to the surfaces of the working chambers a3 and b4 through the base 6. When installing the large mesh screens a11 and b12, they are placed on the two support blocks 14 at an angle. When placing the lower large mesh screen a11 on the support block 14, it is simply laid flat. When placing the large mesh screens a11 and b12 on the support block 14, they are connected to the support block 14 by the fixing screws 15, which restricts the position of the large mesh screens a11 and b12.
[0039] like Figure 1 and Figure 2 As shown, the bottommost sides of the outer walls at both ends of working chambers a3 and b4 are fixedly connected with fixing rings 9, and the topmost sides of the outer walls at both ends of the bottom plate 8 and working chamber b4 are fixedly connected with fixing ends 10. The fixing rings 9 and fixing ends 10 are fixedly connected by threaded connection.
[0040] When connecting and assembling working chambers a3 and b4, place the fixing ring 9 on the fixing end 10 and rotate it clockwise to make a threaded connection and fix it, thus completing the connection and fixation between working chambers a3 and b4.
[0041] The implementation principle of this embodiment is as follows: Working chambers a3 and b4 are assembled together. Then, the fibers to be screened are added into working chamber a3 through the feed inlet 1. Then, the vibration motor 7 is powered on to emit high-frequency vibration amplitude into working chambers a3 and b4. During the vibration process, fibers smaller than the large mesh screen a11 will move downward into working chamber b4 and be screened a second time through the large mesh screen b12. At the same time, fibers smaller than the large mesh screen b12 will continue to move downward and accumulate inside working chamber b4. After the work is completed, working chambers a3 and b4 are separated, and the screened fibers can be taken out. During the vibration of working chambers a3 and b4, the vibration amplitude will drive the slider 18 to move up and down in the limiting groove 17 inside the fixed block 16. During the movement, the connecting rod 19 will drive the unblocking rod 20 upward to lift the fibers blocked inside the large mesh screens a11 and b12, thus preventing blockage.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
