Description

Technical Field

[0001] This utility model relates to the technical field of zinc powder production and processing equipment, and in particular to a multi-stage screening device for zinc powder processing. Background Technology

[0002] Zinc powder is an important industrial raw material, mainly used in coatings, metallurgy, chemicals, pharmaceuticals, agriculture and forestry, and electronics. During the production of zinc powder, depending on the requirements of downstream industries, zinc powder needs to be screened and purified to obtain zinc powder products with different particle sizes and purity levels. This is where zinc powder preparation screening equipment comes in.

[0003] Existing zinc powder screening mechanisms require different zinc powder particle diameters for different customers, necessitating frequent replacement of the sieve plates. However, the existing replacement methods are cumbersome and affect work efficiency. Furthermore, existing zinc powder screening methods are not thorough enough, affecting the screening quality. To address these technical problems, this application proposes a multi-stage screening device for zinc powder processing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-stage screening device for zinc powder processing. By pulling the adjusting block, the limiting block is slid to release the screen's restriction. At the same time, rotating the limiting block locks the screen onto the limiting block, preventing the limiting spring from resetting the limiting block. The screen can then be removed for replacement, making screen replacement more convenient and improving work efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A multi-stage screening device for zinc powder processing includes a screening box for holding zinc powder. Multiple screens are inserted into the left side of the inner wall of the screening box. Multiple sliding grooves are formed on the left side of the screening box. Limiting blocks are slidably connected to the inner walls of each sliding groove. An adjustment assembly is provided on the inner wall of each sliding groove to adjust the displacement of the limiting blocks. The bottom of each limiting block is inserted into the top left side of the screen. Multiple connecting rods are slidably connected to the front side of the inner wall of the screening box. Two brushes are fixedly connected to the bottom of two of the connecting rods, with the bottom of the brushes abutting against the top of the screen. Connecting sliders are fixedly connected to the front sides of the multiple connecting rods. The top rear side of each connecting slider is connected to the top side of the screening box via a reciprocating assembly to drive the connecting slider in reciprocating motion.

[0007] Furthermore, the adjusting assembly includes two adjusting blocks fixedly connected to the left side of the screen, and multiple limiting springs are provided inside the slide groove.

[0008] Furthermore, one end of the limiting spring is fixedly connected to the top of the limiting block, and the other end of the limiting spring is fixedly connected to the top side of the inner wall of the slide groove.

[0009] Furthermore, multiple limiting blocks are fixedly connected to the left side of the screening box, and limiting rotating blocks are rotatably connected to the front and rear sides of the outer wall of the adjusting block.

[0010] Furthermore, the right side of the limiting block abuts against the top side of the limiting block.

[0011] Furthermore, the reciprocating assembly includes a reciprocating toothed ring fixedly connected to the top of the screening box, a turntable rotatably connected to the top of the inner wall of the reciprocating toothed ring, the outer wall of the turntable meshing with the inner wall of the reciprocating toothed ring, and a drive rod rotatably connected to the rear side of the bottom of the turntable, the front end of the drive rod being fixedly connected to the top of the rear side of the connecting slider.

[0012] Furthermore, a servo motor is fixedly connected to the top of the reciprocating gear ring, and the top of the turntable is fixedly connected to the drive end of the servo motor.

[0013] Furthermore, two vibrating blocks are fixedly connected to the outer wall of the connecting rod. The front side of the vibrating block abuts against the front side of the inner wall of the screening box, and the rear side of the vibrating block abuts against the rear side of the inner wall of the screening box.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by pulling the adjusting block, the limiting block is driven to slide, thereby releasing the limitation on the screen. At the same time, the limiting block is rotated to lock it onto the limiting block, so that the limiting spring will not drive the limiting block to reset. The screen can then be pulled out for replacement, making screen replacement more convenient and improving work efficiency.

[0016] 2. In this utility model, the turntable is driven to rotate by a servo motor, which causes the drive rod to reciprocate, so that the brush scrapes the top of the screen back and forth, thereby accelerating the screening speed of zinc powder; at the same time, the two vibrating blocks impact the inner wall of the screening box to prevent the screen from clogging.

[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] Reference Figures 1-3 This utility model provides an embodiment of a multi-stage sieving device for zinc powder processing, comprising a sieving box 1 for holding zinc powder, and multiple screens 5 inserted into the left side of the inner wall of the sieving box 1, wherein the zinc powder is sieved by the screens 5 under gravity; see reference. Figure 4 Multiple sliding grooves are provided on the left side of the screening box 1. Limiting blocks 11 are slidably connected to the inner walls of the sliding grooves. Two adjusting blocks 16 are fixedly connected to the left side of the screen 5. Pulling the adjusting blocks 16 causes the limiting blocks 11 to slide. Multiple limiting springs 10 are provided inside the sliding grooves. One end of the limiting spring 10 is fixedly connected to the top of the limiting block 11, and the other end of the limiting spring 10 is fixedly connected to the top side of the inner wall of the sliding groove. The limiting spring 10 applies elastic force to the limiting blocks 11 to adjust the displacement of the limiting blocks 11. Multiple limiting blocks 9 are fixedly connected to the left side of the screening box 1. Limiting blocks 12 are rotatably connected to the front and rear sides of the outer wall of the adjusting block 16. The right side of the limiting block 12 abuts against the top side of the limiting block 9. Rotating the limiting block 12 will lock it onto the limiting block 9, so that the limiting spring 10 will not drive the limiting blocks 11 to reset. The bottom of the limiting block 11 is inserted into the top left side of the screen 5. The limiting block 11 is inserted into the screen 5 and fixed to it.

[0027] Reference Figures 4-6Multiple connecting rods 6 are slidably connected to the front side of the inner wall of the screening box 1. Two brushes 7 are fixedly connected to the bottom of two connecting rods 6. The bottom of the brushes 7 abuts against the top of the screen 5. The connecting rods 6 drive the brushes 7 to scrape the top of the screen 5, thereby accelerating the screening speed of zinc powder. Connecting sliders 4 are fixedly connected to the front side of the multiple connecting rods 6, so that the connecting rods 6 are connected to the drive rods 14. A reciprocating toothed ring 3 is fixedly connected to the top of the screening box 1. A turntable 13 is rotatably connected to the top of the inner wall of the reciprocating toothed ring 3. The outer wall of the turntable 13 meshes with the inner wall of the reciprocating toothed ring 3. A drive rod 14 is rotatably connected to the rear bottom of the turntable 13. The front end of the drive rod 14 is fixedly connected to the top of the rear side of the connecting slider 4. The rotation of the turntable 13 drives the self-rotating gear. The rotating gear 15 rotates around the turntable 13. When rotating, the rotating gear 15 meshes with the reciprocating gear ring 3, causing the rotating gear 15 to rotate. During the rotation of the rotating gear 15, it drives the drive rod 14 to reciprocate, which in turn drives the connecting slider 4 to reciprocate. The top of the reciprocating gear ring 3 is fixedly connected to the servo motor 2, and the top of the turntable 13 is fixedly connected to the drive end of the servo motor 2. At the same time, the servo motor 2 is started to drive the turntable 13 to rotate. Two vibrating blocks 8 are fixedly connected to the outer wall of the connecting rod 6. The front side of the front vibrating block 8 abuts against the front side of the inner wall of the screening box 1, and the rear side of the rear vibrating block 8 abuts against the rear side of the inner wall of the screening box 1, impacting the inner wall of the screening box 1 to prevent the screen 5 from clogging.

[0028] Working principle: When starting work, zinc powder is injected into the screening box 1. The zinc powder is screened by each screen 5 under gravity. At the same time, the servo motor 2 is started to drive the turntable 13 to rotate. The rotation of the turntable 13 drives the self-rotating gear 15 to rotate around the servo motor 2. When the self-rotating gear 15 rotates, it meshes with the reciprocating gear ring 3, thereby causing the self-rotating gear 15 to rotate. During the process of the self-rotating gear 15 rotating and rotating, it drives the drive rod 14 to reciprocate. The drive rod 14 drives the connecting slider 4 to make the connecting rod 6 slide back and forth. The connecting rod 6 drives the brush 7 to scrape the top of the screen 5, which speeds up the screening speed of zinc powder. When it is necessary to replace the screen 5 to meet production needs, pull the adjusting block 16 to drive the limiting block 11 to slide, releasing the limitation on the screen 5. At the same time, rotate the limiting block 12 to lock it onto the limiting block 9, so that the limiting spring 10 will not drive the limiting block 11 to reset. Pull out the screen 5 for replacement. After the replacement is completed, rotate the limiting block 12 to release the limitation on the limiting block 11. The limiting spring 10 drives the limiting block 11 to reset and insert it into the screen 5 to fix it.
