[0011] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a motor to drive a drive rod to rotate, which in turn drives a gear ring to rotate. The first connecting plate then drives the screening cylinder to rotate. Under centrifugal force, the polyethylene wax inside the screening cylinder moves outward, allowing it to pass through two sets of screening screens in sequence. The polyethylene wax is divided into three parts of different sizes. As the screening cylinder rotates, a scraper removes the polyethylene wax adhering to the inner wall of the screening cylinder and the screening screens. When the scraper contacts the pushing block, the pushing block causes the screening cylinder to vibrate up and down. The screening cylinder moves up and down along the lifting rod via a connecting plate, causing the spring to stretch and compress, thereby intensifying the up and down vibration of the screening cylinder. This prevents polyethylene wax from adhering to the lower wall of the screening cylinder and facilitates the dispersion of the polyethylene wax. The screening effect is enhanced by optimizing the frequency and amplitude of the vibrator and introducing a rotation mechanism. 2. The present invention also utilizes the rotation of the screening cylinder to drive the threaded rod to move up and down. The threaded rod, through the rotating cylinder and connecting rod, drives the outer lifting cylinder to move up and down with the threaded rod. When the threaded rod and the lifting cylinder reach the lower limit position, the first connecting groove and the second connecting groove are connected, allowing polyethylene wax to enter the inner discharge pipe and the outer discharge pipe. The largest piece of polyethylene wax in the middle enters the discharge pipe through the inner discharge pipe and is discharged. The outer discharge pipe carries the polyethylene wax screened by the screening screen into both sides of the isolation cylinder, enters the discharge cylinders on both sides through the inclined platform, and is discharged from the discharge cylinders at different positions, thus enabling the dispersed collection of the screened polyethylene wax.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0015] Please see Figure 1-4This invention provides a technical solution: a multi-layer vibrating screening machine for producing polyethylene wax, comprising a vibrating box 1, a motor 11 mounted on a flange on one side of the upper part of the vibrating box 1, a drive rod 12 connected to the power end of the motor 11 by a coupling, a power gear 13 fixedly welded to the bottom of the drive rod 12, a gear ring 15 meshing with the outer side of the power gear 13, four sets of first connecting plates 14 fixedly welded to the inner side of the gear ring 15, a screening cylinder 2 fixedly welded to the inside of the first connecting plates 14, and two sets of screening screens 3 fixedly welded to the inside of the screening cylinder 2, the aperture of the inner screening screen 3 being larger than that of the outer screening screen 3, so that the polyethylene wax... Capable of tiered screening, the vibrating box 1 has a feed pipe 4 fixedly welded to the upper middle part, ensuring the feed pipe 4 is directly opposite the middle of the screening cylinder 2. The motor 11 drives the drive rod 12 to rotate, which in turn drives the gear ring 15 to rotate via the power gear 13, and then drives the screening cylinder 2 to rotate via the first connecting plate 14. Under centrifugal force, the polyethylene wax inside the screening cylinder 2 moves outwards, passing through two sets of screening meshes 3 in sequence, separating the polyethylene wax into three different sizes. A limiting platform 39 is fixedly welded to the upper interior of the vibrating box 1, and the limiting platform 39 has a lifting groove 40 inside. The screening cylinder 2 and the screening meshes 3 rotate... The lifting trough 40 is dynamically connected to the lower part of the limiting platform 39. Several sets of scrapers 37 are fixedly welded to the lower part of the platform. The scrapers 37 are in close contact with the inner walls of the screening cylinder 2 and the screening screen 3. When the screening cylinder 2 rotates, the scrapers 37 scrape off the polyethylene wax adhering to the inner walls of the screening cylinder 2 and the screening screen 3, preventing the polyethylene wax from sticking to the inner walls of the screening cylinder 2 and the screening screen 3. Several sets of pushing blocks 38 are fixedly welded inside the screening cylinder 2. When the scrapers 37 contact the pushing blocks 38, the pushing blocks 38 drive the screening cylinder 2 to vibrate up and down, preventing polyethylene wax from adhering to the lower wall of the screening cylinder 2 and facilitating the dispersion of the polyethylene wax. The bottom sides of the screening cylinder 2 are fixedly welded with Two sets of connecting plates 5 are connected. A lifting rod 6 is slidably installed inside the connecting plate 5.

A rotating ring 7 is fixedly welded to the lower part of the lifting rod 6. A spring 9 is fixedly welded between the rotating ring 7 and the connecting plate 5. The spring 9 is sleeved on the outside of the lifting rod 6.

A fixing plate 10 is fixedly welded inside the vibration box 1. The fixing plate 10 is set at the lower part of the rotating ring 7 and is used to support the screening cylinder 2. The scraper 37 and the pusher block 38 are arranged with an arc structure facing each other on one side, so that when the scraper 37 contacts the pusher block 38, it can drive the pusher block 38 to move downward and prevent the two from getting stuck. The lower part of the rotating ring 7 has several sets of rolling grooves 41, and rolling balls 35 are rotatably installed inside the rolling grooves 41 to reduce the friction between the rotating ring 7 and the fixed plate 10, so that the rotating ring 7 can drive the screening cylinder 2 to rotate. The vibrating box 1 has a threaded rod 16 installed inside the middle side, and four sets of lifting cylinders 28 are slidably installed inside the screening cylinder 2. The threaded rod 16 and the lifting cylinders 28 have two sets of first connecting grooves 22 on the upper part.

A second connecting groove 24 is opened at the upper part of the inner discharge pipe 23 and the outer discharge pipe 29. When the screening cylinder 2 rotates, it drives the threaded rod 16 to move up and down. The threaded rod 16 drives the outer lifting cylinder 28 to move up and down with the threaded rod 16 through the rotating cylinder 26 and the connecting rod 27. When the threaded rod 16 When the lifting cylinder 28 moves to its lower limit position, the first connecting groove 22 and the second connecting groove 24 connect to facilitate the discharge of the screened polyethylene wax. A second connecting plate 21 is fixedly welded to the inside of the vibrating box 1, and a discharge cylinder 20 is fixedly welded inside the second connecting plate 21. Two sets of rotating grooves 36 are opened on the upper part of the discharge cylinder 20. The lower part of the discharge pipe 29 is rotatably installed inside the rotating grooves 36 to ensure that the inner discharge pipe 23 and the outer discharge pipe 29 do not detach from the discharge cylinder 20 when the screening cylinder 2 rotates. Two sets of third limiting plates 34 are fixedly welded to the lower side of the inner discharge pipe 23 and the outer discharge pipe 29 to prevent the inner discharge pipe 23 and the outer discharge pipe 29 from detaching. The screen cylinder 29 moves up and down, and the third limiting plate 34 does not stick tightly to the upper part of the discharge cylinder 20 to prevent affecting the up and down vibration of the screening cylinder 2. Two sets of limiting rods 19 are slidably installed inside the middle side of the discharge cylinder 20. The upper part of the limiting rod 19 is fixedly welded with a lug 18, and the lug 18 is fixedly welded to the lower first limiting plate 17 to prevent the threaded rod 16 from rotating and to ensure that the threaded rod 16 can move up and down. Two sets of second limiting plates 25 are fixedly welded to the upper part of the threaded rod 16. The second limiting plates 25 are set on the upper and lower sides of the first connecting groove 22 to limit the downward extreme position of the threaded rod 16, thereby controlling the forward and reverse rotation of the motor 11 by setting a sensor.A discharge pipe 31, communicating with the inner discharge pipe 23, is fixedly welded to the middle of the inner side of the discharge cylinder 20. The largest piece of polyethylene wax in the middle is discharged through the discharge pipe 31. An isolation cylinder 30 is fixedly welded inside the discharge cylinder 20, positioned between the isolation cylinder 30 and the rotating groove 36. The isolation cylinder 30 separates the polyethylene wax after it enters the discharge cylinder 20 after being screened by the outer screening screen 3. Two sets of inclined platforms 32 facing opposite directions are fixedly welded to both sides of the inside of the discharge cylinder 20. Two sets of collection pipes 33, directly opposite the lower part of the inclined platforms 32, are fixedly welded to the lower side of the discharge cylinder 20, allowing polyethylene wax of different thicknesses to enter the discharge cylinders 20 on both sides through the inclined platforms 32 and be discharged from the discharge cylinders 20 at different positions.
[0016] Working Principle: In use, polyethylene wax is added into the screening cylinder 2 through the feed pipe 4. The motor 11 drives the drive rod 12 to rotate, which in turn drives the gear ring 15 to rotate via the power gear 13. This, in turn, drives the screening cylinder 2 to rotate via the first connecting plate 14. Under centrifugal force, the polyethylene wax inside the screening cylinder 2 moves outward, allowing it to pass through two sets of screening screens 3 in sequence. The polyethylene wax is then divided into three different sizes. As the screening cylinder 2 rotates, the scraper 37 removes the polyethylene wax adhering to the inner walls of the screening cylinder 2 and the screening screens 3. When the scraper 37 contacts the pushing block 38, the pushing block 38 causes the screening cylinder 2 to vibrate up and down. The screening cylinder 2 moves up and down along the lifting rod 6 via the connecting piece 5, causing the spring 9 to stretch and compress, thereby intensifying the vibration of the screening cylinder. The up-and-down vibration of the screening cylinder 2 prevents polyethylene wax from adhering to the lower wall of the screening cylinder 2 and facilitates the dispersion of polyethylene wax. When the screening cylinder 2 rotates, it drives the threaded rod 16 to move up and down. The threaded rod 16 drives the outer lifting cylinder 28 to move up and down with the threaded rod 16 through the rotating cylinder 26 and the connecting rod 27. When the threaded rod 16 and the lifting cylinder 28 move to the lower limit position, the first connecting groove 22 and the second connecting groove 24 are connected, allowing the polyethylene wax to enter the inner discharge pipe 23 and the outer discharge pipe 29. The largest piece of polyethylene wax in the middle enters the discharge pipe 31 through the inner discharge pipe 23 and is discharged. The outer discharge pipe 29 carries the polyethylene wax screened by the screening screen 3 into both sides of the isolation cylinder 30, enters the discharge cylinders 20 on both sides through the inclined platform 32, and is discharged from the discharge cylinders 20 at different positions.
