Description

Technical Field

[0001] This utility model relates to the field of grinding devices, and more specifically, to a grinding device for conveyor belt spraying. Background Technology

[0002] Conveyor belts, also known as transport belts, are rubber and fiber / metal composite products, or plastic and fabric composite products, used in belt conveyors to carry and transport materials. During the production and processing of conveyor belts, their surfaces need to be coated. Conveyor belts with coatings have high strength and wear resistance, as well as excellent anti-aging properties. Before coating, a grinding device is used to grind the surface of the conveyor belt to ensure better adhesion of the coating to the surface of the conveyor belt.

[0003] Chinese Patent Announcement No. CN215547635U discloses an environmentally friendly conveyor belt grinding device. This device includes a grinding table, a dust cover, and a dust collection device. Positioning rollers are symmetrically installed at both ends of the upper surface of the grinding table. A dust cover is installed near the center of the upper surface of the grinding table. An upper grinding roller and a lower grinding roller are installed inside the dust cover. The upper grinding roller is fixed at both ends to bearings embedded in both ends of the dust cover. One end of the upper grinding roller has a rotating shaft that passes through the dust cover and is fitted with a driven wheel A. The two ends of the lower grinding roller have rotating shafts that pass through strip-shaped slots at both ends of the dust cover and are fixed to support seats. One end of the lower grinding roller, located at the driven wheel A, has a rotating shaft that passes through the support seat and is fitted with a driven wheel B. The two support seats are slidably installed in a fixed seat and fixed by fixing screws C. The fixed seat is installed on the dust cover. A stop block is installed on the dust cover at the lower end of the fixed seat, and a fixing screw B is screwed onto the stop block.

[0004] However, in the aforementioned patent, the distance between the upper and lower grinding rollers is relatively fixed, which can only grind conveyor belts of a single thickness specification and cannot be applied to conveyor belts of different specifications. In addition, since the sides of the conveyor belt cannot be ground, there will be a certain number of burrs on the sides of the conveyor belt, resulting in lower quality of the ground conveyor belt, which is inconvenient and has certain limitations in use.

[0034] Example 1:

[0035] Please see Figure 1-5 A grinding device for conveyor belt spraying includes a base 1. A screw 11 is rotatably connected inside the base 1. The screw 11 has threads on both sides of its outer wall in opposite directions. A limit rod 12 is fixedly connected inside the base 1. A first moving block 13 is threadedly connected to the outer wall of one screw 11, and a second moving block 15 is threadedly connected to the outer wall of the other screw 11. Both the first and second moving blocks 13 and 15 are slidably connected to the limit rod 12. A grinding roller 14 is rotatably connected between the first and second moving blocks 13 and 15. A synchronous belt 2 is connected between the two parts. A handle 21 is fixedly connected above the synchronous belt 2. A drive gear 16 is rotatably connected to the outside of the second moving block 15. A bevel gear 17 is fixedly connected to one end of the drive gear 16 and one end of the first grinding roller 14. The two bevel gears 17 mesh. A strip gear 18 is rotatably connected to one side of the base 1. The outer wall of the strip gear 18 meshes with the outer wall of the drive gear 16. A motor 19 is fixedly connected above the base 1. The output end of the motor 19 is fixedly connected to the top of the strip gear 18.

[0036] In this embodiment, when the first motor 19 starts, it drives the bar gear 18 to rotate. Since the bar gear 18 meshes with the drive gear 16, the rotation of the bar gear 18 will drive the drive gear 16 to rotate. When the drive gear 16 rotates, it will drive the first grinding roller 14 to rotate through the meshing of the bevel gear 17. In addition, when the operator turns the handle 21, it will drive the screw 11 to rotate. When the screw 11 rotates, the first moving block 13 and the second moving block 15 on the upper and lower sides of the screw 11 will slide on the outer wall of the limit rod 12. By changing the direction of the screw 11, the distance between the two first grinding rollers 14 can be made closer or farther away from each other, thereby satisfying the grinding of conveyor belts of different thicknesses.

[0037] Example 2:

[0038] Please see Figure 1-5 A grinding device for conveyor belt spraying includes a dust-collecting plate 24 installed inside a base 1. A conduit 23 is fixedly connected to the middle of one side of the dust-collecting plate 24. A vacuum cleaner 22 is fixedly connected to one end of the conduit 23 and is fixedly connected to the top of the base 1. A rotating plate 25 is rotatably connected to the top of the base 1. Connecting rods 26 are rotatably connected to both ends of the rotating plate 25. Connecting frames 27 are rotatably connected to the ends of the two connecting rods 26. Both connecting frames 27 are slidably connected to the top of the base 1. A second grinding roller 28 is rotatably connected to the bottom of the connecting frames 27. A second motor 29 is fixedly connected inside the connecting frames 27. The output end of the second motor 29 is fixedly connected to the top of the second grinding roller 28. A third motor 3 is fixedly connected to the top of the base 1. The output end of the third motor 3 is fixedly connected to the center of the top of the rotating plate 25.

[0039] In this embodiment, when motor 3 rotates, it drives the rotating plate 25 to rotate. During this process, the connecting frame 27 will slide relative to the top of the base 1, changing the distance between the two connecting frames 27. After motor 29 starts, it drives the second grinding roller 28 to rotate. By changing the distance between the two connecting frames 27, the distance between the two second grinding rollers 28 is controlled. The second grinding roller 28 is used to grind the side of the conveyor belt. When the first grinding roller 14 and the second grinding roller 28 are grinding the top, bottom and sides of the conveyor belt, the operator can start the vacuum cleaner 22. After the vacuum cleaner 22 is started, it will generate suction, and the debris and other impurities generated during grinding will enter the interior of the vacuum plate 24.

[0040] The working principle of this utility model is as follows: The operator can turn the handle 21 to adjust the distance between the two No. 1 grinding rollers 14 according to the thickness of the conveyor belt to be ground. Then, the No. 1 motor 19 is started to make the two No. 1 grinding rollers 14 rotate simultaneously to grind the upper and lower surfaces of the conveyor belt. Then, the part of the conveyor belt after being ground by the No. 1 grinding rollers 14 is passed between the two No. 2 grinding rollers 28. At this time, the operator can start the No. 3 motor 3 and the No. 2 motor 29 respectively to adjust the distance between the two No. 2 grinding rollers 28 and make the No. 2 grinding rollers 28 rotate. The No. 2 grinding rollers 28 are used to grind the side of the conveyor belt. When the No. 1 grinding rollers 14 and the No. 2 grinding rollers 28 are grinding the upper, lower and side surfaces of the conveyor belt, the operator can start the vacuum cleaner 22. After the vacuum cleaner 22 is started, it will generate suction, and the debris and other impurities generated during grinding will enter the interior of the dust collection plate 24.

[0041] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
