Description

Technical Field

[0001] This invention relates to the field of graded conveying technology, and in particular to a graded conveying device for preventing PE wax powder from sticking together. Background Technology

[0002] PE wax powder has the physical characteristics of fine particle size, light texture and high viscosity. During storage, unloading and transportation, it is very easy to cause problems such as powder sticking to the silo wall, material bridging, arching and blockage due to electrostatic adsorption and extrusion. This seriously affects the continuity of powder transportation and the uniformity of discharge. At the same time, PE wax powder with different particle size and particle size needs to be accurately graded and transported to meet the usage requirements of different processing steps. Existing PE wax powder conveying equipment technology is relatively traditional, mostly relying on fixed stirring structures or gravity feeding to achieve material feeding. It cannot specifically break up the adhesion and accumulation layer between the powder and the bin wall, resulting in poor anti-adhesion effect. Moreover, traditional disturbance structures can only act on local areas of the bin wall and cannot effectively disturb the powder in the center of the bin. The material is prone to forming bridging voids, leading to failures such as material interruption, blockage, and uneven discharge. At the same time, traditional conveying equipment does not have the function of rapid and accurate classification and conveying, and cannot quickly classify and convey PE wax powder with different properties to the corresponding workstations. The material is seriously mixed, the sorting efficiency is low, and it cannot achieve integrated continuous operation of powder anti-adhesion pretreatment and classification and conveying, making it difficult to meet the production needs of refined, continuous, and high-efficiency classification and conveying of PE wax powder.

[0003] To address the above problems, this invention proposes a PE wax powder anti-adhesion grading and conveying device. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing PE wax powder conveying equipment, which mostly rely on fixed stirring structures or gravity feeding to achieve material feeding.

The two sets of elastic fitting assemblies are connected to a flexible inner lining structure. The two ends of the flexible inner lining structure are fixedly connected to the inner wall of the powder feeding hopper. The two sets of elastic fitting assemblies are also respectively connected to two elastic composite mesh belt structures. The middle part of the two elastic composite mesh belt structures is fixedly connected to the same central bearing sphere. The linkage drive assembly drives the elastic fitting assemblies to move, causing the flexible inner lining structure and the elastic composite mesh belt structure to vibrate. The multi-stage conveying mechanism includes a conveying component and a spiral conveying device mounted on the conveying component.

[0006] Preferably, the conveying assembly includes a screw drive motor and a screw conveying shaft. The screw drive motor is fixedly installed at the discharge port position below the powder feed hopper. The output shaft of the screw drive motor is fixedly connected to the screw conveying shaft. The screw conveying shaft is rotatably installed at the discharge port below the powder feed hopper via bearings.

[0007] Preferably, the spiral conveying shaft is located in the discharge port below the rotary screening cylinder and the powder feed hopper. The rotary screening cylinder is connected to the powder feed hopper, and the rotary screening cylinder is rotatably mounted on the discharge port of the powder feed hopper through a bearing. A second transmission bevel gear is fixedly connected to one end of the rotary screening cylinder.

[0008] Preferably, the other end of the rotary screening cylinder is provided with a discharge port, and the rotary screening cylinder is also rotatably mounted on a screw conveyor via bearings, the screw conveyor being fixedly connected to a supporting base frame.

[0009] Preferably, the elastic composite mesh belt structure consists of multiple radial elastic belts and two latitudinal elastic belts, with the radial elastic belts arranged in an intersecting manner at the top and bottom positions, so that the mesh holes formed between the multiple radial elastic belts and the two latitudinal elastic belts are staggered.

[0010] Preferably, the linkage drive assembly includes a dual-output shaft motor and a rotating outer ring plate. The two output shafts of the dual-output shaft motor are respectively fixedly connected to a first transmission bevel gear and a transmission gear, and the first transmission bevel gear meshes with the second transmission bevel gear.

[0011] Preferably, the rotating outer ring plate is rotatably mounted on the fixed ring via a bearing, and the fixed ring is fixedly connected to the powder feed hopper. The flexible inner lining structure is made of rubber.

[0012] Preferably, annular wave plates are fixedly connected to the top and bottom of the rotating outer ring plate, and annular transmission gear rings are fixedly connected to the lower annular wave plate, the annular transmission gear rings meshing with transmission gears.

[0013] Preferably, each group of elastic fitting components consists of several units, with each elastic fitting component in a staggered manner at the upper and lower positions. Each elastic fitting component includes a mounting guide sleeve, in which a reciprocating movable rod is slidably connected. One end of the reciprocating movable rod is provided with a wave follower wheel, which can roll on an annular wave plate.

[0014] Preferably, the other ends of the upper and lower reciprocating rods are respectively fixedly connected to two elastic composite mesh belt structures, and an elastic return spring is fixedly connected to the other end of the reciprocating rod near the flexible inner lining structure. One end of the elastic return spring is fixedly connected to the mounting guide sleeve.

[0015] Compared with the prior art, the present invention provides a PE wax powder anti-adhesion grading and conveying device, which has the following beneficial effects: 1. This PE wax powder anti-adhesion and grading conveying device, through the linkage drive component's annular corrugated plate and elastic component, can make the flexible inner lining structure vibrate, effectively reducing the problems of powder adhering to the wall and caking. At the same time, during the vibration process, the flexible inner lining structure can synchronously drive the internal elastic composite mesh belt structure to shake disorderly, dynamically disturbing the powder. Moreover, the meshes of the two elastic composite mesh belt structures are staggered, intercepting caking powder at multiple levels. At the same time, it can effectively disperse the central powder accumulation structure, destroy the powder bridging and arching formation conditions, thereby ensuring uniform feeding and stable conveying of PE wax powder.

[0016] 2. This PE wax powder anti-adhesion grading and conveying device can sieve the powder through the rotating screening cylinder of the conveying component. The first transmission bevel gear of the linkage drive component can drive the second transmission bevel gear, so that the rotating screening cylinder can roll and screen, increasing the screening area. The use of flow screening can improve screening efficiency. In combination with the screw conveyor, it can quickly classify and screen PE wax powder of different specifications according to the particle size, loose state and purity difference of PE wax powder and convey it to different designated work stations, realizing powder classification and collection and zoned conveying.

[0017] 3. This PE wax powder anti-adhesion grading and conveying device, through a linkage drive component that can be linked with an elastic coordination component to achieve shaking of the flexible inner lining structure, while the two elastic composite mesh belt structures maintain shaking, thus continuously ensuring that the powder is in a loose, uniform, non-adhesive, and non-bridging state, avoiding problems such as material blockage, adhesion, and uneven discharge. This provides a stable, continuous, and homogeneous material foundation for subsequent grading and conveying operations. Secondly, the linkage drive component also links the conveying component for rolling screening, which, together with the screw conveyor, performs grading and conveying, preventing the powder from accumulating and adhering again after long-term retention, thus consolidating the anti-adhesion and arch-breaking effect. The combination of these two methods solves the problems of easy adhesion, bridging, and unstable discharge in traditional PE wax powder conveying, while achieving efficient and precise grading and conveying of powder. This significantly improves the overall operational stability, continuity, and fine processing level of the device, making it suitable for the industrial conveying and production needs of large-volume, high-precision PE wax powder.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In the description of this invention, it should be understood that the terms upper, lower, front, back, left, right, top, bottom, inside, outside, etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0022] Example 1: Refer to Figures 1-5 and Figures 7-10 A PE wax powder anti-adhesion grading and conveying device includes a powder feeding mechanism 100, and a multi-stage conveying mechanism 200 is arranged below the powder feeding mechanism 100. The powder feeding mechanism 100 includes a powder feeding hopper 101, on which a linkage drive assembly 105 is provided. The linkage drive assembly 105 includes a dual-output shaft motor 1051 and a rotating outer ring plate 1052. The two output shafts of the dual-output shaft motor 1051 are respectively fixedly connected to a first transmission bevel gear 1053 and a transmission gear 1055. The first transmission bevel gear 1053 meshes with a second transmission bevel gear 2023. The rotating outer ring plate 1052 is rotatably mounted on a fixed ring 1056 via bearings. The rotating outer ring plate 1052 can be kept stable by the bearings, causing the two annular wave plates to rotate. 1057 rotates synchronously, and the fixed ring 1056 is fixedly connected to the powder feed hopper 101. The flexible inner lining structure 106 is made of rubber. Annular corrugated plates 1057 are fixedly connected to the top and bottom of the rotating outer ring plate 1052. An annular transmission gear ring 1054 is fixedly connected to the lower annular corrugated plate 1057. The annular transmission gear ring 1054 meshes with the transmission gear 1055. A set of elastic fitting components 103 is provided on both the upper and lower sides of the powder feed hopper 101. Each set of elastic fitting components 103 consists of several components, and each elastic fitting component 103 in the upper and lower positions is staggered. The staggered arrangement of the upper and lower rows of elastic mating components 103 allows them to contact the convex surface of the annular corrugated plate 1057 at different frequencies, thereby causing the flexible inner lining structure 106 to vibrate at different frequencies, and the two elastic composite mesh belt structures 102 to vibrate at different frequencies. This improves the anti-sticking effect and looseness of the PE wax powder. The elastic mating component 103 includes a mounting guide sleeve 1033, in which a reciprocating movable rod 1031 is slidably connected. One end of the reciprocating movable rod 1031 is provided with a wave follower wheel 1034. The rolling property of 34 can reduce the frictional resistance with the annular wave plate 1057 and improve the smoothness of the cooperation between the wave follower wheel 1034 and the annular wave plate 1057. The wave follower wheel 1034 can roll on the annular wave plate 1057. The other ends of the upper and lower reciprocating rods 1031 are respectively fixedly connected to two elastic composite mesh belt structures 102. The other end of the reciprocating rod 1031 near the flexible inner lining structure 106 is fixedly connected to an elastic return spring 1032. One end of the elastic return spring 1032 is fixedly connected to the mounting guide sleeve 1033. Two sets of elastic fitting components 103 are connected to a flexible inner lining structure 106. The two ends of the flexible inner lining structure 106 are fixedly connected to the inner wall of the powder feed hopper 101. The two sets of elastic fitting components 103 are also respectively connected to two elastic composite mesh belt structures 102. Each elastic composite mesh belt structure 102 consists of multiple radial elastic belts and two latitudinal elastic belts, with the radial elastic belts arranged in a crisscross pattern at the top and bottom. This staggers the mesh openings formed between the multiple radial elastic belts and the two latitudinal elastic belts. Through the staggered arrangement of the mesh openings of the upper and lower elastic composite mesh belt structures 102, if agglomerated PE wax powder is discharged from the upper elastic composite mesh belt structure 102... 2. Falling downwards, due to the staggered mesh of the upper and lower elastic composite mesh belt structures 102, the lower elastic composite mesh belt structure 102 can effectively intercept the clumped PE wax powder, which facilitates the grading and loosening of PE wax powder and improves the loosening effect. Moreover, the method of using the elastic composite mesh belt structure 102 to shake and loosen the PE wax powder can avoid damaging the quality of the PE wax powder. The middle part of the two elastic composite mesh belt structures 102 is fixedly connected to the same central bearing ball 104. The linkage drive component 105 drives the elastic cooperation component 103 to move, so that the flexible inner lining structure 106 and the elastic composite mesh belt structure 102 perform shaking action. The multi-stage conveying mechanism 200 includes a conveying component 202 and a screw conveyor 203 disposed on the conveying component 202.

[0023] In this embodiment: the dual-output shaft motor 1051 drives the transmission gear 1055 to rotate. The transmission gear 1055 and the annular transmission gear ring 1054 drive the lower annular wave plate 1057 to rotate. The two annular wave plates 1057 are connected by rotating outer ring plate 1052, so that the two annular wave plates 1057 rotate synchronously. The convex surface of the annular wave plate 1057 can push the wave follower wheel 1034 and the reciprocating rod 1031 to move. The reciprocating rod 1031 drives the flexible inner lining structure 106 to move. At the same time, the elastic return spring 1032 deforms. When the wave follower wheel 1034 moves to the concave surface of the annular wave plate 1057, the elastic return spring 1032 drives the reciprocating rod 1057 to move. 31. Reset until the wave follower wheel 1034 rolls again to the convex surface of the annular wave plate 1057, which can make the reciprocating rod 1031 move again. This allows the reciprocating rod 1031 to move back and forth, which in turn drives the flexible inner lining structure 106 to shake, effectively reducing the problem of powder adhering to the wall and caking. At the same time, during the shaking process, the flexible inner lining structure 106 can also drive the internal elastic composite mesh belt structure 102 to shake disorderly, dynamically disturbing the powder. Moreover, the meshes of the two elastic composite mesh belt structures 102 are staggered, intercepting the caking powder in multiple stages. At the same time, it can effectively disperse the central powder accumulation structure, destroy the powder bridging and arching formation conditions, thereby ensuring the uniform feeding and stable conveying of PE wax powder.

[0024] Example 2: Refer to Figure 4 and Figure 6 A PE wax powder anti-adhesion grading and conveying device includes a conveying assembly 202, which includes a screw drive motor 2021 and a screw conveying shaft 2022. The screw drive motor 2021 is fixedly installed at the discharge port below the powder feed hopper 101. The output shaft of the screw drive motor 2021 is fixedly connected to the screw conveying shaft 2022. The screw conveying shaft 2022 is rotatably mounted on the discharge port below the powder feed hopper 101 via bearings. The screw conveying shaft 2022 is located between a rotary screening cylinder 2024 and... The rotary screening cylinder 2024 is connected to the powder feeding hopper 101 through the discharge port below the powder feeding hopper 101. The rotary screening cylinder 2024 is rotatably mounted on the discharge port of the powder feeding hopper 101 through bearings. A second transmission bevel gear 2023 is fixedly connected to one end of the rotary screening cylinder 2024, and a discharge port is provided at the other end of the rotary screening cylinder 2024. The rotary screening cylinder 2024 is also rotatably mounted on the screw conveyor 203 through bearings. The screw conveyor 203 is fixedly connected to the supporting and fixed base frame 201.

[0025] In this embodiment: the screw drive motor 2021 drives the screw conveyor shaft 2022 to rotate, and the screw conveyor shaft 2022 can transport PE wax powder into the rotary screening cylinder 2024. The rotary screening cylinder 2024 can screen the PE wax powder, and the first transmission bevel gear 1053 of the linkage drive component 105 can drive the second transmission bevel gear 2023. The second transmission bevel gear 2023 drives the rotary screening cylinder 2024 to rotate, so that the rotary screening cylinder 2024 can roll and screen, increasing the screening area of ​​PE wax powder. The use of flow screening can improve screening efficiency. Thus, in conjunction with the screw conveyor equipment 203, PE wax powder of different specifications can be quickly classified, screened and transported to different designated workstations according to the particle size, loose state and purity difference of PE wax powder, realizing powder classification and collection and zoned transportation.

[0026] Example 3: Reference Figures 1-5 A PE wax powder anti-adhesion grading and conveying device includes a powder feeding mechanism 100, which includes a powder feeding hopper 101. A linkage drive assembly 105 is provided on the powder feeding hopper 101. A set of elastic fitting assemblies 103 are provided on both the upper and lower sides of the powder feeding hopper 101. The two sets of elastic fitting assemblies 103 are connected to a flexible inner lining structure 106. The two ends of the flexible inner lining structure 106 are fixedly connected to the inner wall of the powder feeding hopper 101. The two sets of elastic fitting assemblies 103 are also respectively connected to two elastic composite mesh belt structures 102. The middle part of the two elastic composite mesh belt structures 102 is fixedly connected to the same central bearing ball 104. The linkage drive assembly 105 drives the elastic fitting assemblies 103 to move, causing the flexible inner lining structure 106 and the elastic composite mesh belt structure 102 to vibrate. The multi-stage conveying mechanism 200 includes a conveying component 202 and a screw conveyor 203 disposed on the conveying component 202.

[0027] In this embodiment: the linkage drive component 105 can be linked with the elastic coordination component 103 to realize the shaking of the flexible inner lining structure 106. At the same time, the two elastic composite mesh belt structures 102 maintain shaking, thereby continuously ensuring that the powder is in a loose, uniform, non-adhesive, and non-bridging state, avoiding problems such as material blockage, adhesion, and uneven discharge. This provides a stable, continuous, and homogeneous material foundation for subsequent classification and conveying operations. Secondly, the linkage drive component 105 also links the conveying component 202 for rolling screening, and then cooperates with the screw conveyor 203 for classification and conveying, avoiding long-term retention of powder and re-accumulation and adhesion, consolidating the anti-adhesion and anti-bridging effect. The combination of the two solves the problems of easy adhesion, easy bridging, and unstable discharge of traditional PE wax powder conveying. At the same time, it realizes efficient and accurate classification and conveying of powder, significantly improving the overall operational stability, continuity, and fine processing level of the device, and adapting to the industrial conveying production needs of large-volume and high-precision PE wax powder.

[0028] Working Principle: During the classification and conveying of PE wax powder, the PE wax powder enters the powder feed hopper 101 and falls onto the elastic composite mesh belt structure 102. This causes the dual-output shaft motor 1051 to drive the transmission gear 1055 and the annular transmission gear ring 1054. The annular transmission gear ring 1054 drives the lower annular corrugated plate 1057 to rotate, which in turn drives the outer ring plate 1052 to rotate, causing the upper and lower annular corrugated plates 1057 to rotate synchronously. The uneven surface of the annular corrugated plate 1057 can compress the wave follower wheel 1034, which in turn drives the reciprocating rod 1031 to move. The reciprocating rod 1031 causes the elastic return spring 1032 to deform, and the reciprocating rod 1031 also causes the flexible inner lining structure 106 to move. When the wave follower wheel 1034 moves to the concave surface of the annular corrugated plate 1057, the elastic return spring 1032 drives the reciprocating rod 1031 to return to its original position, thus restoring the elastic... The return spring 1032, in conjunction with the uneven surface of the annular wave plate 1057, enables multi-point shaking of the flexible inner lining structure 106, preventing PE wax powder from sticking together. At the same time, the reciprocating rod 1031 drives the elastic composite mesh belt structure 102 to shake, thereby eliminating PE wax powder agglomeration and allowing the PE wax powder to flow smoothly. The PE wax powder falls to the lower layer of the elastic composite mesh belt structure 102 and continues to be treated by shaking to prevent agglomeration. After treatment, the PE wax powder enters the discharge port of the powder feed hopper 101. At this time, the screw drive motor 2021 drives the screw conveyor shaft 2022 to transport the PE wax powder into the rotary screening cylinder 2024. At the same time, the first transmission bevel gear 1053 and the second transmission bevel gear 2023 drive each other, which allows the rotary screening cylinder 2024 to roll and screen. The finer PE wax powder enters the screw conveyor 203 and is output through the screw conveyor 203, while the coarser PE wax powder is discharged through the discharge port of the rotary screening cylinder 2024.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
