Description

Technical Field

[0001] This invention relates to the field of grinding and rust removal equipment technology, specifically to an environmentally friendly mobile grinding mechanism for strip steel. Background Technology

[0002] Grinding is a processing method that uses mechanical, chemical, or electrochemical processes to reduce the surface roughness of a workpiece, thereby obtaining a bright and smooth surface. Compared to traditional pickling and rust removal, it has the advantage of being environmentally friendly. Grinding does not improve the dimensional or geometric accuracy of a workpiece; rather, it aims to achieve a smooth surface or a mirror finish. Sometimes it is also used to eliminate shine (matte finish). Grinding wheels or grinding belts are usually used as grinding tools. The grinding belt rotates at high speed to grind the metal surface and remove rust.

[0003] Existing strip grinding devices grind and remove rust from the strip surface by rotating a grinding belt. However, these devices have the following problems: When the strip is installed, the outer surface of the grinding belt is designated as the grinding surface. Since the outer surface of the grinding belt is in contact with the strip surface, a single grinding belt can only grind one side of the strip. If both sides of the strip need to be ground, two grinding operations or two grinding belts must be installed, which is inconvenient. Summary of the Invention

[0004] To address the aforementioned technical shortcomings, the present invention aims to provide an environmentally friendly mobile strip grinding mechanism. By incorporating a grinding component, the inner side of the grinding belt on the grinding component simultaneously grinds the upper and lower surfaces of the strip, thereby solving the problems existing in the grinding mechanisms described in the background art.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: The present invention provides an environmentally friendly mobile strip steel grinding mechanism, including a base, a grinding assembly, and a drive mechanism for driving the grinding assembly to move. The grinding assembly includes a vertical plate, on which a pair of drive rollers are symmetrically rotatably connected. A grinding belt is driven between the two drive rollers. The drive rollers drive the grinding belt to rotate, and the upper and lower inner surfaces of the grinding belt grind the upper and lower surfaces of the strip steel, respectively. A pair of pressing mechanisms are symmetrically connected to the surface of the vertical plate, and the grinding belt is tightly attached to the upper and lower surfaces of the strip steel through the pressing mechanisms. Two pairs of tension rollers for supporting the grinding belt are symmetrically connected on the vertical plate. The two tension rollers and the drive roller are arranged in a triangle. The inner side of the grinding belt is set as the grinding surface, and the drive roller is in contact with the outer side of the grinding belt, while the tension roller is in contact with the inner side of the grinding belt. By setting the inner side of the grinding belt as the grinding surface and pressing the upper and lower grinding belts together by the belt pressing mechanism, the present invention ensures that the grinding belt is always in contact with the strip steel. When the grinding belt rotates, its inner side can grind the upper and lower surfaces of the strip steel at the same time, realizing the grinding effect of a single grinding belt on the strip steel and improving the grinding efficiency of the strip steel.

[0006] As a preferred embodiment of the present invention, the driving mechanism includes a drive motor, a drive shaft connected to the drive motor, a driven shaft rotatably connected to the base via a shaft bracket, and two drive rollers fixedly connected to the drive shaft and the driven shaft respectively. The drive motor drives the drive shaft and the driven shaft to rotate simultaneously.

[0007] As a preferred embodiment of the present invention, a transmission belt is provided between the driven shaft and the driving shaft, and pulleys that are rotatably connected to the transmission belt are installed on both the driven shaft and the driving shaft.

[0008] As a preferred embodiment of the present invention, the tension roller is rotatably connected to the slider, the vertical plate is provided with a sliding groove that is slidably connected to the slider, and a first spring is fixedly connected between the slider and one end of the sliding groove. The first spring applies elastic force to the slider, so that the tension roller keeps the grinding belt in a taut state, thus ensuring the grinding effect.

[0009] As a preferred embodiment of the present invention, the pressing mechanism includes a mounting frame, a rotating frame rotatably connected to the mounting frame, and a pair of pressure rollers for pressing the outer side of the grinding belt rotatably connected to both ends of the rotating frame. The two pressure rollers press the upper and lower grinding belts together, so that the upper and lower grinding belts are always in contact with the surface of the strip steel, and the grinding belt grinds the surface of the strip steel when it moves.

[0010] As a preferred embodiment of the present invention, an outer ring is fixedly connected to the rotating frame, and a ratchet is fixedly connected to the mounting frame. The ratchet is located at the center of the outer ring, and a pawl that cooperates with the ratchet is rotatably connected to the outer ring. A second spring is fixedly connected between the pawl and the inner wall of the outer ring. The second spring keeps the pawl in contact with the ratchet, so that the rotating frame can only rotate in the direction of pressing the grinding belt, maintaining the pressing state of the grinding belt, and the spacing between the upper and lower grinding belts can be adjusted to adapt to grinding strips of different thicknesses.

[0011] As a preferred embodiment of the present invention, the mounting bracket is slidably connected to the vertical plate, and a threaded sleeve is fixedly connected to the mounting bracket. A threaded rod that is threadedly connected to the threaded sleeve is rotatably connected to the vertical plate. Rotating the threaded rod can adjust the position of the pressing mechanism and change the pressing position of the grinding belt.

[0012] As a preferred embodiment of the present invention, the vertical plate is provided with a through hole for the strip steel to pass through, and a pair of connecting frames are symmetrically fixedly connected on both sides of the through hole. The connecting frames are connected with positioning wheels for limiting the sides of the strip steel. The stability of the strip steel is ensured by limiting the sides of the strip steel through the two positioning wheels.

[0013] As a preferred embodiment of the present invention, a moving mechanism for driving the strip steel forward is installed on the vertical plate. The moving mechanism includes a frame, a pair of rotating rollers are rotatably connected to the frame, and a servo motor for driving the rotating rollers to rotate is installed on the frame. Both rotating rollers are fixedly connected with meshing gears. The servo motor drives the two rotating rollers to rotate in opposite directions simultaneously, thereby driving the strip steel forward to move stably.

[0014] The beneficial effects of this invention are as follows:

[0015] This invention sets the inner side of the grinding belt as the grinding surface, and the grinding assembly is equipped with a drive roller, a tension roller, and a belt pressing mechanism. The belt pressing mechanism keeps the inner sides of the upper and lower layers of the grinding belt in contact with the upper and lower surfaces of the strip steel, so that the upper and lower surfaces of the strip steel can be ground simultaneously when the grinding belt moves, thereby improving the grinding efficiency.

[0016] The pressing mechanism of this invention, by having a pressing roller, an outer ring, a ratchet, and a pawl, can adjust the vertical distance between the two pressing rollers, thereby adjusting the spacing between the upper and lower grinding belts, so that the grinding belt can adapt to grinding steel strips of different thicknesses.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0027] like Figures 1-7 As shown, the present invention is an environmentally friendly mobile grinding mechanism for strip steel, including a base 4, a grinding assembly 3, and a drive mechanism 1 for driving the grinding assembly 3. Both the drive mechanism 1 and the grinding assembly 3 are mounted on the base 4. The drive mechanism 1 includes a drive motor 11, which is mounted on the base 4. A drive shaft 12 is connected to the drive motor 11. A driven shaft 14 is rotatably connected to the base 4 via a shaft bracket 16. A transmission belt 15 is connected between the driven shaft 14 and the drive shaft 12. Both the driven shaft 14 and the drive shaft 12 are equipped with pulleys 13 that are rotatably connected to the transmission belt 15. The drive motor 11 simultaneously drives the drive shaft 12 and the driven shaft 14 to rotate.

[0028] like Figures 3-5As shown, the grinding assembly 3 includes a vertical plate 31, which is mounted on the base 4. A pair of drive rollers 32 are symmetrically rotatably connected to the vertical plate 31. The two drive rollers 32 are fixedly connected to the drive shaft 12 and the driven shaft 14, respectively. The drive motor 11 simultaneously drives the two drive rollers 32 to rotate in the same direction. A grinding belt 34 is connected between the two drive rollers 32. The inner side of the grinding belt 34 is set as the grinding surface, and the drive rollers 32 are in contact with the outer side of the grinding belt 34. When the drive rollers 32 rotate, they drive the grinding belt 34 to rotate. The upper and lower inner sides of the grinding belt 34 are in contact with the upper and lower surfaces of the strip steel 5, respectively. When the grinding belt 34 rotates, it can grind the upper and lower surfaces of the strip steel 5 simultaneously. Two pairs of tension rollers 37 for supporting the grinding belt 34 are symmetrically connected to the vertical plate 31. The tension rollers 37 are in contact with the inner side of the grinding belt 34. Each drive roller 32 is connected to two tension rollers. The two tension rollers 37 and the drive roller 32 are arranged in a triangular pattern, which increases the contact area between the drive roller 32 and the grinding belt 34. This allows the drive roller 32 to rotate and drive the grinding belt 34 to rotate. The advantage of this design is that since the drive roller 32 needs to drive the grinding belt 34 to rotate, a large frictional force is required between them. The drive roller 32 contacts the outer side of the grinding belt 34 instead of directly contacting the inner side of the grinding belt 34, which avoids damage to the grinding surface of the inner side of the grinding belt 34 when the drive roller 32 rotates, thus affecting the grinding effect. The tension roller 37 is rotatably connected to the slider 36. The vertical plate 31 is provided with a groove 35 that is slidably connected to the slider 36. A first spring 38 is fixedly connected between the slider 36 and one end of the groove 35. The first spring 38 applies a pressure force to the slider 36, so that the tension roller 37 keeps the grinding belt 34 in a taut state.

[0029] like Figure 3 and Figure 6As shown, to ensure that the inner side of the grinding belt 34 remains in contact with the surface of the strip steel 5, a pair of pressing mechanisms 33 are symmetrically connected to the surface of the vertical plate 31. The grinding belt 34 is pressed tightly against the upper and lower surfaces of the strip steel 5 through the pressing mechanisms 33. The pressing mechanism 33 includes a mounting frame 331, which is fixedly connected to the surface of the vertical plate 31. A rotating frame 332 is rotatably connected to the mounting frame 331. A pair of pressure rollers 333 for pressing the outer side of the grinding belt 34 are rotatably connected to both ends of the rotating frame 332. Under the pressure of the pressure rollers 333, the inner sides of the upper and lower grinding belts 34 are pressed tightly against the upper and lower surfaces of the strip steel 5. An outer ring 335 is fixedly connected to the rotating frame 332, and the outer ring 335 rotates together with the rotating frame 332. A ratchet 334 is fixedly connected to the outer ring 335. The ratchet 334 is located at the center of the outer ring 335. A pawl 336 that cooperates with the ratchet 334 is rotatably connected to the outer ring 335. A second spring 337 is fixedly connected between the pawl 336 and the inner wall of the outer ring 335. The second spring 337 makes the pawl 336 tightly adhere to the ratchet 334. Through the arrangement of the pawl 336 and the ratchet 334, the rotating frame 332 can rotate in the direction of pressing the grinding belt 34, so that the grinding belt 34 is tightly adhered to the surface of the strip steel 5. If it is necessary to rotate in the opposite direction, the pawl 336 can be manually moved to disengage it from the ratchet 334. The spacing between the upper and lower layers of the grinding belt 34 can also be adjusted through the belt pressing mechanism 33 to achieve the purpose of grinding strip steel of different thicknesses.

[0030] Preferred, such as Figure 5 As shown, the mounting bracket 331 is slidably connected to the vertical plate 31, the pressing mechanism 33 can move left and right on the surface of the vertical plate 31, and a threaded sleeve 338 is fixedly connected to the mounting bracket 331. A threaded rod 39 that is threadedly connected to the threaded sleeve 338 is rotatably connected to the vertical plate 31. Rotating the threaded rod 39 can adjust the pressing mechanism 33 to move to the sides or the middle, and adjust the pressing position of the grinding belt 34 to adapt to strips of different widths.

[0031] Preferred, such as Figure 4 As shown, the vertical plate 31 is provided with a through hole 310 for the strip steel 5 to pass through. A pair of connecting frames 311 are symmetrically fixed on both sides of the through hole 310. The connecting frames 311 are connected with positioning wheels 312 for limiting the side of the strip steel 5. The positioning wheels 312 are installed on the connecting frames 311 by nuts, and the position of the positioning wheels 312 on the connecting frames 311 can be adjusted. The positioning wheels 312 limit the side of the strip steel 5 to ensure the stability of the position of the strip steel 5.

[0032] like Figure 1 and Figure 7As shown, a moving mechanism 2 for driving the strip steel 5 forward is installed on the vertical plate 31. The moving mechanism 2 includes a frame 21, which is fixedly connected to the vertical plate 31. A pair of rotating rollers 22 are rotatably connected to the frame 21. When the rotating rollers 22 rotate, they drive the strip steel 5 forward. A servo motor 23 for driving the rotating rollers 22 to rotate is installed on the frame 21. Both rotating rollers 22 are fixedly connected to meshing gears 24. The servo motor 23 drives the two rotating rollers 22 to rotate in opposite directions at the same time, thereby driving the strip steel 5 forward while it is being polished.

[0033] Working principle: During use, the strip steel 5 passes through the through hole 310 on the vertical plate 31. The drive motor 11 drives the two drive rollers 32 to rotate simultaneously. The rotation of the drive rollers 32 drives the grinding belt 34 to rotate. When the grinding belt 34 rotates, the inner surfaces of the upper and lower grinding belts 34 grind the upper and lower surfaces of the strip steel 5 simultaneously. This allows a single grinding belt 34 to grind the upper and lower surfaces of the strip steel 5 simultaneously, improving grinding efficiency. At the same time, the moving mechanism 2 drives the strip steel 5 to move forward, improving the automation of the device.
