Description

Technical Field

[0001] The present invention relates to the technical field of vibrating screen meshes, and specifically to a vibrating screen mesh with a high-strength plastic frame. Background Art

[0002] A vibrating screen mesh with a high-strength plastic frame refers to a screening component formed by using high-strength engineering plastics (such as polyurethane, polypropylene, etc.) as the skeleton or frame and combining with a screen mesh (which can be a metal woven mesh, a polyurethane screen surface or a rubber screen surface). This design utilizes the corrosion resistance, wear resistance, light weight and shock absorption performance of plastics, while ensuring the stability and screening efficiency of the screen mesh. The main function of the vibrating screen mesh with a high-strength plastic frame is to accurately separate and classify the mixed materials according to the particle size through its vibrating motion.

[0003] The aperture sizes of the existing vibrating screen meshes are all fixed. When screening a kind of material, although the materials with the required volume size can be screened out, when more volume sizes of the material need to be screened, since the aperture size of the screen mesh cannot be adjusted, it is necessary to replace the screen meshes with different aperture sizes to complete the corresponding screening. This process increases the labor time of the staff, reduces the screening efficiency of the materials, and thus reduces the use effect of the vibrating screen mesh with a plastic frame.

[0004] Therefore, we propose a vibrating screen mesh with a high-strength plastic frame to solve the problems raised above. Summary of the Invention

[0005] The purpose of the present invention is to provide a vibrating screen mesh with a high-strength plastic frame to solve the problem in the above background art that since the aperture size of the screen mesh cannot be adjusted, it is necessary to replace the screen meshes with different aperture sizes to complete the corresponding screening.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A vibrating screen mesh with a high-strength plastic frame, including a screen mesh body. A screen mesh frame is fixedly installed at the top of the screen mesh body. A plurality of adjustment holes are opened on one side of the outer wall of the screen mesh body. Two strip-shaped grooves are opened on the outer surface of the screen mesh frame. Three strip-shaped sliders are movably embedded in the inner surfaces of the two strip-shaped grooves respectively. On one side of the outer walls of the six strip-shaped sliders, connection bars are fixedly installed respectively. At the bottom of the six connection bars, two clamping bars are fixedly installed. A plurality of clamping holes are opened on one side of the outer walls of the two clamping bars. Adjustment rods are movably inserted into the inner surfaces of the plurality of clamping holes respectively, and the outer surfaces of the plurality of adjustment rods are movably inserted into the plurality of adjustment holes and also movably inserted into the interior of the screen mesh body. On one side of the outer walls of the two clamping bars, bumps are fixedly installed respectively. Two channel-shaped blocks are fixedly installed on the outer surface of the screen mesh frame.

[0007] Preferably, two limiting grooves are formed in the inner walls of the two groove-shaped blocks, and limiting sliders are movably embedded in the inner walls of the four limiting grooves.

[0008] Preferably, connection blocks are fixedly installed on one sides of the outer walls of the two groove-shaped blocks, and handle screws are threadedly connected to one sides of the outer walls of the two connection blocks.

[0009] Preferably, extrusion blocks are rotatably connected to one sides of the outer walls of the two handle screws, and one sides of the outer walls of the four limiting sliders are fixedly connected to the outer surfaces of the two extrusion blocks. A plurality of round holes are formed in the top of the screen body.

[0010] Preferably, first springs are fixedly installed at the bottoms of the inner walls of the plurality of round holes, and bump caps are fixedly installed at the tops of the plurality of first springs.

[0011] Preferably, a scale is arranged on one side of the outer wall of the screen frame, and two moving grooves are formed in the bottom of the screen body.

[0012] Preferably, moving sliders are movably embedded in the inner walls of the two moving grooves, and a strip-shaped plate is fixedly installed between the bottoms of the two moving sliders.

[0013] Preferably, a concave seat is fixedly installed at the bottom of the strip-shaped plate, and a plurality of second springs are fixedly installed on one side of the inner wall of the concave seat.

[0014] Preferably, top columns are fixedly installed at the tops of the plurality of second springs, connecting rods are fixedly installed at the bottoms of the plurality of top columns, and the outer surfaces of the plurality of connecting rods are movably inserted into the inside of the concave seat.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. Pass multiple adjusting rods through multiple positioning holes on two positioning bars and also through multiple adjusting holes inside the screen body. At this time, under the action of two strip-shaped grooves and six strip-shaped sliders, the connecting bar drives the two positioning bars to move a suitable distance to one side, and makes the multiple adjusting rods located in multiple screening holes on the screen body, reducing the original aperture of the screening holes. At this time, two bumps are located in two groove-shaped blocks. Rotate two screw rods with handles. Under the action of four limiting grooves and four limiting sliders, it drives the two pressing blocks to move stably and limits the two bumps in the two groove-shaped blocks. When it is necessary to screen a larger volume of this material, only need to rotate the two screw rods with handles, and then under the action of the scale, move the two positioning bars and multiple adjusting rods to the other side, and the appropriate screen aperture can be adjusted according to the size of the required material volume, which has adjustability and does not require replacing the screen to screen different volume sizes of the same material, saving the labor time of the staff and improving the screening efficiency of the material.

[0018] 2. After screening the material, through the action of multiple round holes, multiple first springs and multiple convex point caps, the activity degree of the material on the screen body is improved, making it easier to be located at the screening holes for screening. Some materials will block and get stuck inside the screening holes of the screen body. At this time, move multiple connecting rods through the connecting plate, drive multiple ejector posts to move downward and away from the screening holes of the screen body, and make multiple second springs in a compressed state. Through the action of two moving grooves and two moving sliders, move the strip-shaped plate to a suitable position, and make multiple ejector posts correspond to a row of screening holes of the screen body. Then release the connecting plate. Under the action of multiple second springs, multiple ejector posts will move upward along multiple circular holes and eject the materials in this row of screening holes. The operation process is simple and improves the cleaning efficiency of the screen body. Description of the Drawings

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-8, the present invention provides a technical solution: a high-strength plastic frame vibrating screen mesh, including a screen body 1, a screen frame 2 is fixedly installed on the top of the screen body 1, a plurality of adjustment holes 3 are opened on one side of the outer wall of the screen body 1, two strip-shaped grooves 4 are opened on the outer surface of the screen frame 2, three strip-shaped sliders 5 are movably embedded in the inner walls of the two strip-shaped grooves 4, a connecting strip 6 is fixedly installed on one side of the outer walls of the six strip-shaped sliders 5, two clamping strips 7 are fixedly installed at the bottoms of the six connecting strips 6, a plurality of clamping holes 8 are opened on one side of the outer walls of the two clamping strips 7, an adjusting rod 9 is movably inserted into the inner walls of the plurality of clamping holes 8, and the outer surfaces of the plurality of adjusting rods 9 are movably inserted into the plurality of adjustment holes 3, and the outer surfaces of the plurality of adjusting rods 9 are movably inserted into the screen body 1, a convex block 10 is fixedly installed on one side of the outer walls of the two clamping strips 7, two groove-shaped blocks 11 are fixedly installed on the outer surface of the screen frame 2, two limiting grooves 12 are opened on the inner walls of the two groove-shaped blocks 11, a limiting slider 13 is movably embedded in the inner walls of the four limiting grooves 12, a connecting block 14 is fixedly installed on one side of the outer walls of the two groove-shaped blocks 11, a handle screw 15 is threadedly connected to one side of the outer walls of the two connecting blocks 14, an extrusion block 16 is rotatably connected to one side of the outer walls of the two handle screws 15, and the outer surfaces of the four limiting sliders 13 are fixedly connected to the outer surfaces of the two extrusion blocks 16.

[0031] In this embodiment, a plurality of adjustment holes 3 are formed on one side of the screen body 1. The plurality of adjustment holes 3 are equidistantly formed according to the screen holes on the screen body 1. Then, strip-shaped grooves 4 are formed on both sides of the screen frame 2. Three strip-shaped sliders 5 are movably embedded in each of the two strip-shaped grooves 4. The three strip-shaped sliders 5 on the same side are all provided with clamping strips 7 through three connecting strips 6. One side of each of the two clamping strips 7 is in contact with the opposite side of the screen frame 2. Then, a plurality of clamping holes 8 are equidistantly formed on the two clamping strips 7. Next, a plurality of adjusting rods 9 are sequentially inserted into the plurality of clamping holes 8 on the clamping strip 7 on this side, then pass through the plurality of adjustment holes 3 formed on the screen body 1, and penetrate out from the plurality of clamping holes 8 on the clamping strip 7 on the other side. The plurality of adjusting rods 9 have a movable space in the plurality of adjustment holes 3. At this time, the plurality of adjusting rods 9 are equidistantly located beside the plurality of screen holes on the screen body 1. Before using this screen, according to the size of the material to be screened, the plurality of adjusting rods 9 are moved to appropriate positions beside the plurality of screen holes on the screen body 1, that is, through six connecting strips 6, and under the action of the two strip-shaped grooves 4 and six strip-shaped sliders 5, the two clamping strips 7 are simultaneously moved to one side by an appropriate distance, and the specified distance can be moved according to the function of the scale 20, so that the plurality of adjusting rods 9 are located at appropriate positions in the plurality of screen holes, and the aperture of the screen holes on the screen body 1 can be changed. At this time, the two clamping strips 7 have moved forward by a specified distance, and the convex blocks 10 installed on one side of the outer walls of the two clamping strips 7 have moved a specified distance along the inside of the groove-shaped blocks 11. Then, rotate the two handle screws 15 to rotate them inside the connecting block 14. Since two limiting grooves 12 are formed on the inner surfaces of the two groove-shaped blocks 11, one end of each of the two handle screws 15 is rotatably connected with a pressing block 16, and the outer surface of each pressing block 16 is fixedly connected to the outer wall of one side of the two limiting sliders 13 correspondingly. Therefore, by rotating the two handle screws 15, the two pressing blocks 16 can be stably moved to one side, and the convex blocks 10 in the two groove-shaped blocks 11 can be limited, so that the two clamping strips 7 and the plurality of adjusting rods 9 can be limited at specified positions, which is convenient for subsequent vibration screening. When the material of this volume size has been screened and it is necessary to screen materials with a slightly larger volume, it is not necessary to pour out the material and replace it with another screen. Only need to rotate the two handle screws 15 so that the two pressing blocks 16 no longer press the two convex blocks 10, and then through the action of the six connecting strips 6, six strip-shaped sliders 5 and the scale 20, move the two clamping strips 7 to the other side by a specified distance, and make the plurality of adjusting rods 9 move a specified distance in the plurality of adjustment holes 3, so that the plurality of apertures on the screen body 1 gradually become larger, and the aperture becomes the volume size of the material to be screened. Then rotate the two handle screws 15 again, so that the two pressing blocks 16 limit the two convex blocks 10 in the two groove-shaped blocks 11 again. It has adjustability and does not require replacing the screen to screen different volume sizes of the same material, saving the labor time of the staff.The screening efficiency of materials is improved.

[0032] As Figure 1 , Figure 2 and Figures 5-8 shown, a plurality of round holes 17 are provided at the top of the screen body 1. At the bottom of the inner walls of the plurality of round holes 17, first springs 18 are fixedly installed. At the top of the plurality of first springs 18, bump caps 19 are fixedly installed. A scale 20 is provided on one side of the outer wall of the screen frame 2. Two moving grooves 21 are provided at the bottom of the screen body 1. Moving sliders 22 are movably embedded in the inner surfaces of the two moving grooves 21. A strip plate 23 is fixedly installed between the bottoms of the two moving sliders 22. A concave seat 24 is fixedly installed at the bottom of the strip plate 23. A plurality of second springs 25 are fixedly installed on one side of the inner wall of the concave seat 24. At the top of the plurality of second springs 25, ejector posts 26 are fixedly installed. At the bottom of the plurality of ejector posts 26, connecting rods 27 are fixedly installed. The outer surfaces of the plurality of connecting rods 27 are movably inserted into the inside of the concave seat 24. A plurality of circular holes 28 are provided at the top of the strip plate 23. The outer surfaces of the plurality of ejector posts 26 are movably inserted into the plurality of circular holes 28. A connecting plate 29 is fixedly installed between the bottoms of the plurality of connecting rods 27.

[0033] In this embodiment, a plurality of circular holes 17 are provided on the screen body 1, and each circular hole 17 is equidistantly located between every two screen holes. Then, a first spring 18 is installed at the bottom of the inner wall of each circular hole 17, and the height of the first spring 18 is slightly higher than the surface of the screen body 1. Then, a convex cap 19 is fixedly installed on the top of each first spring 18. When the material is vibrated and screened on the screen body 1 and in the screen frame 2, the action of the plurality of first springs 18 and the plurality of convex caps 19 makes it difficult for the material to fall between the two screen holes, making it easier to be screened at the screen holes, thereby improving the screening efficiency. Secondly, movable grooves 21 are provided on both sides of the bottom of the screen body 1, and movable sliders 22 are movably embedded in the inner walls of the two movable grooves 21, and a strip plate 23 is installed between the bottoms of the two movable sliders 22. Because a concave seat 24 is installed at the bottom of the strip plate 23, a second spring 25 is installed between the plurality of top columns 26 of the concave seat 24, and the diameter of each top column 26 just corresponds to The size of the original aperture of the screen body 1 is such that a connecting rod 27 is installed at the bottom of each top column 26, and each connecting rod 27 passes through the concave seat 24 and is connected together through the connecting plate 29. After the screen body 1 is used, the original aperture of the screen body 1 will still be stuck with material. If it is cleaned from the top downward, it is easy to damage the original aperture of the screen body 1. At this time, multiple connecting rods 27 and multiple top columns 26 are moved simultaneously through the connecting plate 29, so that each top column 26 moves downward along the circular hole 28 opened on the strip plate 23. The strip plate 23 is moved to a designated position through the action of the two moving grooves 21 and the two moving sliders 22, and the multiple top posts 26 are made to correspond to the row of sieve holes. Then the connecting plate 29 is loosened, and under the action of the multiple second springs 25, the multiple top posts 26 are driven to move upward along the multiple circular holes 28 and the corresponding sieve holes, and the materials in the sieve holes are ejected, thus completing the cleaning of the materials stuck in the posts on the sieve body 1. The operation process is simple and the efficiency of cleaning the sieve body 1 is improved.

[0034] Usage method and working principle of this device: First, since three connecting bars 6 are installed on the top of each of the two clamping bars 7, and the strip-shaped sliders 5 installed on one side of the outer walls of the six connecting bars 6 are all movably embedded in the two strip-shaped grooves 4, the two clamping bars 7 move along both sides of the screen frame 2. At this time, a plurality of adjusting rods 9 are passed through a plurality of clamping holes 8 opened on the two clamping bars 7 and simultaneously through a plurality of adjusting holes 3. Then, before using the screen body 1, according to the volume of the screening material, under the action of the scale 20, the two clamping bars 7 are moved to appropriate positions, and the plurality of adjusting rods 9 are moved to designated positions in the plurality of adjusting holes 3, so as to change the original aperture size of the screen body 1 and meet the required aperture size at this time. At this time, the two bumps 10 installed on one side of the two clamping bars 7 are both located in the two groove-shaped blocks 11. Then, rotate the two handle screws 15. Since the four limit sliders 13 installed on the outer surfaces of the two pressing blocks 16 are all movably embedded in the four limit grooves 12, the two pressing blocks 16 move steadily downward, and the two bumps 10 are limited in the two groove-shaped blocks 11, so as to limit the two clamping bars 7 and the plurality of adjusting rods 9 in designated positions. When the screening of the material with a specified volume size is completed and the screening of a larger volume in the material is required, it is not necessary to transfer the material to another screen. Only need to rotate the two handle screws 15, loosen the two pressing blocks 16, and then through the action of the six connecting bars 6, the six strip-shaped sliders 5 and the scale 20, move the two clamping bars 7 and the plurality of adjusting rods 9 to the other side by a specified distance, so that the plurality of adjusting rods 9 move out of the corresponding screen holes, and the aperture of the screen holes can be made larger. Then, through the same operation as above, the bumps 10 installed on one side of the two clamping bars 7 are limited in the two groove-shaped blocks 11, and the subsequent material screening can be completed. When the material is screened, some materials will block in the screen holes of the screen body 1 and get stuck in the screen holes. At this time, move the plurality of connecting rods 27 through the connecting plate 29, so that they drive the plurality of ejector posts 26 to move downward and away from the screen holes of the screen body 1, and the plurality of second springs 25 installed between the plurality of ejector posts 26 and the concave seat 24 are in a compressed state. Then, through the action of the two moving grooves 21 and the two moving sliders 22, move the strip-shaped plate 23, the concave seat 24 and the plurality of ejector posts 26 to appropriate positions, so that the plurality of ejector posts 26 will correspond to a row of screen holes of the screen body 1. Then, loosen the connecting plate 29. Under the action of the plurality of second springs 25, the plurality of ejector posts 26 will move upward along the plurality of circular holes 28 and eject the materials in the row of screen holes, and the cleaning of the materials stuck on the screen body 1 is completed. Generally speaking, according to the volume of the material to be screened, select and adjust the appropriate screen aperture, which has adjustability. There is no need to replace the screen to screen different volume sizes of the same material, saving the labor time of the staff, improving the screening efficiency of the material, and thus improving the use effect of the screen of this plastic frame vibrating screen.
