Description

Technical Field

[0001] This utility model belongs to the field of steel plate polishing technology, specifically a steel plate surface polishing device for logistics equipment production. Background Technology

[0002] Logistics consists of various stages including the transportation of goods, services, distribution, warehousing, packaging, handling and loading / unloading, processing, and related logistics information. The current logistics industry requires a large amount of equipment to work together to meet basic logistics needs.

[0003] Steel plates are the most commonly used material in the manufacture of existing logistics equipment. These plates require polishing during manufacturing to remove burrs or achieve a bright finish, thus meeting the production needs of logistics equipment. This polishing process requires specialized equipment, most commonly a surface polishing machine. Existing surface polishing machines primarily use conveyor belts to transport the steel plates, followed by polishing belts to grind and polish the surface. However, in practical use, the applicant has found that the polishing requirements for steel plates vary depending on the processing needs of the logistics equipment. This is typically achieved by adjusting the grit of the polishing belt. However, existing surface polishing machines generally only support one grit of polishing belt, leading to the need for repeated disassembly and replacement of the belt during adjustments, which is cumbersome and affects processing efficiency. To address these issues, a steel plate surface polishing device for logistics equipment production is proposed. Utility Model Content

[0029] Polishing assembly 3 and conveying assembly 2 are mounted on base frame 1;

[0030] The above-mentioned structure constitutes a steel plate polishing device for manufacturing logistics equipment, wherein the conveying component 2 supports and conveys the steel plate, and then the polishing component 2 polishes the steel plate.

[0031] refer to Figures 1 to 5As shown, there are multiple polishing components 3. Each polishing component 3 includes two supports 4, with a multi-faceted cylinder 5 rotatably connected to each support 4. A self-locking stepper motor 6 is fixedly mounted on one of the supports 4. The stepper motor 6 is connected to the multi-faceted cylinder 5 via an output shaft. A vertical mounting plate 7 is fixedly connected to each face of the multi-faceted cylinder 5. Two rotating rollers 8 and a tensioning roller 9 are mounted on the vertical mounting plate 7. Polishing abrasive belts 10 are fitted onto the rotating rollers 8 and the tensioning roller 9. The mesh size of the polishing abrasive belts 10 on each face of the multi-faceted cylinder 5 is different. A tensioning assembly 11 is connected to a tensioning roller 9 and is rotatably mounted on a vertical mounting plate 7. The tensioning assembly 11 is mounted on the vertical mounting plate 7. A driven gear 12 is fixedly connected to one of the rotating rollers 8. A support frame 13 is fixedly connected to one of the supports 4. An external spline shaft 14 is rotatably mounted on the support frame 13. A drive motor 15 is fixedly mounted on the support frame 13 and is connected to the external spline shaft 14 via an output shaft. An internal spline sleeve 16 is telescopically connected to the external spline shaft 14. One side of the internal spline sleeve 16 is fixedly connected to... A main gear 17 is connected, meshing with a driven gear 12. A push plate 18 is rotatably connected to the other side of the inner spline sleeve 16. A hydraulic rod 19 is fixedly mounted on the support frame 13, and the output shaft of the hydraulic rod 19 is connected to the push plate 18. In this structure, personnel can fix polishing sand belts 10 of different mesh sizes onto the rotating rollers 8 and tensioning rollers 9 on different surfaces of the polygonal cylinder 5 as needed. Then, the stepper motor 6 is started to drive the polygonal cylinder 5 to rotate, thereby rotating the polishing sand belts 10 on the corresponding surfaces to the lower side. Then, the hydraulic rod 19 is started to drive the push plate 18. The plate 18 moves, and the push plate 18 drives the inner spline sleeve 16 to extend on the outer spline shaft 14, thereby connecting the main gear 17 with the driven gear 12. Then, the drive motor 15 is started to drive the outer spline shaft 14 to rotate. The outer spline shaft 14 will drive the inner spline sleeve 16 to rotate, thereby driving the main gear 17 to rotate, which in turn drives the driven gear 12 to rotate, thereby driving the rotating roller 8 to rotate. At this time, the rotating roller 8, together with another rotating roller 8 and the tensioning roller 9, drives the polishing sand belt 10 to rotate, thereby achieving the polishing and grinding of the steel plate.

[0032] Each face of the multi-faceted cylinder 5 is equipped with a rotating roller 8 and a tensioning roller 9 for fixing polishing sand belts 10, so that each face of each multi-faceted cylinder 5 can be fixed with polishing sand belts 10 of different grits.

The main conveying roller 21, in conjunction with the secondary conveying roller 22, drives the conveyor belt 23 to rotate, thereby realizing the lifting and conveying of steel plates. When grinding steel plates of different thicknesses, the hydraulic rods 25 can be activated to adjust the height of the conveyor belt 23, thereby adapting to the grinding requirements of steel plates of different thicknesses.

[0035] refer to Figures 1 to 5 As shown, multiple idlers 26 for conveyor belts 23 are rotatably connected to the bracket 20. This structure utilizes the idlers 26 to improve the load-bearing capacity of the conveyor belts 23.

[0036] refer to Figures 1 to 5 As shown, the polishing assembly 3 is provided with a protective shell 33, which is fixedly installed on the base frame 1. Inspection doors 34 are hinged to both side walls of the protective shell 33. This structure uses the protective shell 33 to cover the polishing equipment, thereby preventing the equipment from injuring people. At the same time, the inspection doors 34 make it convenient to open the protective shell 33 to replace the polishing belt 10 and perform equipment maintenance.

[0037] refer to Figures 1 to 5 As shown, the tensioning assembly 11 includes two fixed plates 27, with screws 28 rotatably connected to the two fixed plates 27.

A guide rod 30 is slidably connected to the shaft seat 29, and both ends of the guide rod 30 are fixedly mounted on the two fixed plates 27 respectively. In this structure, when a person rotates the screws 28, the tensioning roller 9 on the shaft seat 29 moves, thereby causing the tensioning roller 9 to tension and fix the polishing sand belt 10.

[0038] refer to Figures 1 to 5 As shown, a strip hole 31 is provided on the vertical mounting plate 7, and the tension roller 9 passes through the strip hole 31 and is connected to the shaft seat 29.

[0040] It should be noted that the above-mentioned steel plate polishing device is used for polishing steel plates used in the manufacture of logistics equipment.

[0041] The implementation principle of a steel plate surface polishing device for logistics equipment production according to an embodiment of this application is as follows: In use, personnel fix polishing sand belts 10 of different mesh sizes onto rotating rollers 8 and tensioning rollers 9 on different surfaces of a multi-faceted cylinder 5 as needed. Then, a stepper motor 6 is started to drive the multi-faceted cylinder 5 to rotate, thereby rotating the polishing sand belts 10 on the corresponding surfaces downwards. Then, hydraulic rod one 19 is started to move the push plate 18, which in turn causes the inner spline sleeve 16 to extend from the outer spline shaft 14, thereby connecting the main gear 17 with the driven gear 12. Then, according to the steel plate thickness, personnel start hydraulic rod two 25 to adjust the height of the conveyor belt 23 to fit the thickness. The operator places the steel plate on the conveyor belt 23, then starts the conveyor motor 24 to drive the main conveyor roller 21 to rotate. The main conveyor roller 21, in conjunction with the driven conveyor roller 22, drives the conveyor belt 23 to rotate, thereby realizing the lifting and conveying of the steel plate. Then, the drive motor 15 is started to drive the outer spline shaft 14 to rotate. The outer spline shaft 14 will drive the inner spline sleeve 16 to rotate, thereby driving the main gear 17 to rotate, which in turn drives the driven gear 12 to rotate, thereby driving this rotating roller 8 to rotate. At this time, the rotating roller 8, in conjunction with another rotating roller 8 and the tensioning roller 9, drives the polishing sand belt 10 to rotate, thereby realizing the polishing and grinding of the steel plate used for manufacturing logistics equipment.
