Description

Technical Field

[0001] This utility model relates to the field of material distribution equipment technology, specifically a material distribution device for a grinding equipment for ultra-high molecular weight polyethylene rods. Background Technology

[0002] A material sorting device is a commonly used device for sorting materials. When ultra-high molecular weight polyethylene rods are being ground, different particle sizes of residual material are produced. It is necessary to sort the residual material of different particle sizes. The material sorting device can meet the requirement of reusing the residual material.

[0003] A search revealed Chinese patent publication number CN213164834U, which discloses a material distribution device for a grinding equipment for ultra-high molecular weight polyethylene rods. The device includes a material distribution box, with connecting rods fixedly installed on both sides of the top of the box. The top of each connecting rod is connected to a mounting plate. One end of the material distribution box is connected to a receiving hopper, and the other end is connected to a first discharge hopper. A second discharge hopper is connected to one side of the bottom of the box, and a third discharge hopper is connected to the other side. A speed regulator is connected inside the receiving hopper. The structure includes a material distribution box with a material distribution screen inside, and a connecting shaft running through the inside of the material distribution screen. A vibration mechanism is connected between the connecting shaft and the material distribution box. In use, this technical solution only uses a single-component material distribution screen, and the screen mesh has screen holes of different diameters arranged on the same plane. This results in different particle sizes of residual materials flowing together on a single screen surface, blurring the grading boundaries, insufficient screening accuracy, and easy misclassification of materials. Fine and medium-sized particles are not completely separated, and the recovered residual materials have mixed particle sizes. To address these issues, a material distribution device for ultra-high molecular weight polyethylene rod grinding equipment is provided. Utility Model Content

[0025] Reference Figures 1 to 4 In this embodiment of the present invention, a material distribution device for a grinding equipment for ultra-high molecular weight polyethylene rods includes:

[0026] The waste material processing and sorting mechanism 1 is used to screen the waste material generated during the grinding of ultra-high molecular weight polyethylene rods.

[0027] Screen bucket vibration mechanism 2 is set inside the waste material processing and distribution mechanism 1. Screen bucket vibration mechanism 2 is used to vibrate waste material processing and distribution mechanism 1.

[0028] The waste material processing and sorting mechanism 1 includes a main housing 11. Two sets of inner guide grooves 12 are symmetrically arranged on the inner side of the main housing 11. A double-layer screening hopper 13 is arranged inside the main housing 11. Sliding blocks adapted to the inner guide grooves 12 are fixedly connected to both sides of the double-layer screening hopper 13. The double-layer screening hopper 13 is slidably connected to the inner side of the main housing 11. An inlet 14 is opened above the double-layer screening hopper 13. A guide plate 15 is fixedly connected to the inner side of the double-layer screening hopper 13 near the inlet 14. Two sets of closely spaced pressing rollers 16 are rotatably connected to the inner side of the double-layer screening hopper 13 near its lower end. Two sets of first drive motors 17 are fixedly connected to the side of the double-layer screening hopper 13. The movable ends of the two sets of first drive motors 17 pass through the double-layer screening hopper 13 and are fixedly connected to a corresponding set of pressing rollers 16. A first screening plate is fixedly connected to the inner side of the double-layer screening hopper 13 below the pressing rollers 16. 18. A first discharge port 19 is provided on the inner side of the double-layer screening hopper 13 above the first screening plate 18. A second screening plate 110 is fixedly connected to the inner side of the double-layer screening hopper 13 below the first screening plate 18. Multiple sets of screening holes are provided on the inner sides of both the first screening plate 18 and the second screening plate 110. The inner screening holes of the first screening plate 18 are larger than the inner screening holes of the second screening plate 110. The guide plate 15, the first screening plate 18 and the second screening plate 110 are staggered and inclined on the inner side of the main shell 11. The first discharge port 19 and the second discharge port 111 are respectively provided on different sides of the double-layer screening hopper 13. A second discharge port 111 is provided on the inner side of the double-layer screening hopper 13 above the second screening plate 110. A conveyor belt 112 is provided on the inner side of the main shell 11 below the second screening plate 110. A third discharge port 113 is provided on the inner side of the main shell 11 below the conveyor belt 112.

[0029] After the residual material enters through the feed inlet 14, it is guided by the guide plate 15 to the crushing roller 16. The two sets of counter-rotating crushing rollers 16 crush some of the excessively large lumps of residual material. Then the material falls to the first screening plate 18 for primary screening. The residual material with a particle size larger than the screen holes of the first screening plate 18 slides along the inclined first screening plate 18 to the first discharge port 19 and is discharged. The residual material passing through the first screening plate 18 continues to fall to the second screening plate 110 for secondary screening. The residual material with a particle size between the two screen holes slides along the second screening plate 110 to the second discharge port 111 and is discharged. The residual material with a particle size smaller than the screen holes of the second screening plate 110 falls directly into the conveyor belt 112 and is finally discharged through the third discharge port 113.

[0030] The screen bucket vibration mechanism 2 includes an L-shaped bracket 21. A second drive motor 22 is fixedly connected to the top of the L-shaped bracket 21. A fixed bracket 23 is fixedly connected to the top of the L-shaped bracket 21. Two sets of connecting rod turntables 24 are arranged between the second drive motor 22 and the fixed bracket 23. The movable end of the second drive motor 22 is fixedly connected to the center of one set of connecting rod turntables 24. The fixed bracket 23 is rotatably connected to the center of the other set of connecting rod turntables 24. A horizontal rotating rod 25 is fixedly connected between the two sets of connecting rod turntables 24. One end of a connecting column 26 is rotatably connected to the outside of the horizontal rotating rod 25. A rotating block 27 is rotatably connected to the other end of the connecting column 26. The L-shaped bracket 21 is fixedly connected between the second screening plate 110 and the conveyor belt 112 on the inner side wall of the main housing 11. The rotating block 27 is fixedly connected to the bottom of the second screening plate 110.

[0031] When the second drive motor 22 drives the connecting rod turntable 24 to rotate, it drives the connecting column 26 to rotate eccentrically through the horizontal rotating rod 25, which in turn pushes the rotating block 27 to generate reciprocating vibration. This vibration is transmitted to the entire double-layer screening hopper 13 through the second screening plate 110, causing it to generate horizontal vibration along the inner guide groove 12 through the sliding blocks on both sides, accelerating the sorting process of residual material on the screening plate, while preventing the screen holes from clogging.

[0032] The working principle of this utility model is as follows: During operation, the residue generated from grinding ultra-high molecular weight polyethylene rods enters the device through the feed inlet 14 at the top of the double-layer screening hopper 13. The residue is first guided by the inclined guide plate 15 to the two sets of opposing rotating crushing rollers 16. At this time, the first drive motor 17 drives the crushing rollers 16 to rotate at high speed, crushing and refining the oversized agglomerated residue to ensure the uniformity of subsequent screening.

[0033] After the crushed material falls naturally, it first contacts the upper first screening plate 18. Material with a particle size larger than this screen aperture slides along the inclined surface of the first screening plate 18 to the first discharge port 19 and is discharged, while material meeting the requirements continues to fall through the screen apertures. The material then enters the second screening plate 110 for secondary sorting. Material with a particle size between the two screening apertures slides along the second screening plate 110 to the second discharge port 111 and is discharged, while finer material passes through the screen apertures and falls into the conveyor belt 112.

[0034] During this process, the second drive motor 22 of the screen bucket vibration mechanism 2 drives the connecting rod turntable 24 to rotate, which in turn drives the connecting column 26 to make eccentric movements through the horizontal rotating rod 25. This movement is converted into high-frequency vibration by the rotating block 27, and the vibration energy is transmitted to the entire double-layer screen bucket 13 through the second screening plate 110. The double-layer screen bucket 13 generates horizontal reciprocating vibration along the inner guide groove 12 of the main shell 11 through the sliding blocks on both sides, which on the one hand promotes the rapid separation of materials on the first screening plate 18 and the second screening plate 110; on the other hand, it effectively prevents the screen holes from clogging.

[0035] Finally, the smallest qualified residue is conveyed by conveyor belt 112 to the third discharge port 113 for centralized discharge, completing the three-stage sorting operation. The entire device achieves automated grading of residue with different particle sizes through the synergistic effect of crushing, vibrating screening and mechanical conveying. The L-shaped support 21 and fixed support 23 of the main shell 11 provide stable support for the vibration mechanism, ensuring the reliability of the system operation.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
