Description

Technical Field

[0001] This utility model relates to the field of rolling mill grinding technology, and more specifically, it relates to a grinding device for rolling mills in ferrous metal smelting. Background Technology

[0002] In the production of USB data cables (such as Type-C) or high-frequency charging cables, the core conductor is an extremely thin copper foil or copper strip. This copper strip is made by repeatedly cold rolling a rough-rolled copper rod through a series of rolling drums. Under long-term high-pressure operation, the surface of the rolling drum will produce tiny wear, scratches, pits or copper adhesion. Therefore, the rolling drum needs to be polished.

[0003] The patent with publication number CN213561504U discloses a three-roll calender roller grinding device, which includes a flat iron. The left and right ends of the flat iron are respectively connected to an adjusting screw A and an adjusting screw B. The adjusting screw A is surrounded by a wedge-shaped wooden block A, a spring and a pre-tightening nut in sequence from the inside to the outside. The adjusting screw B is surrounded by a wedge-shaped wooden block B, a spring, a sleeve handle and a pre-tightening nut in sequence from the inside to the outside. The pre-tightening nut can adjust the pressure between the wedge-shaped wooden block and the roller to ensure the accuracy and precision of grinding. The spring can ensure pressure while ensuring a certain range of motion. The sleeve handle is used to move the entire device horizontally to grind the entire roller.

[0004] The grinding device in the above scheme can use its own surface as a reference to grind and remove small blemishes, attachments and other impurities on the roller surface, thereby improving the accuracy of equipment use. However, this grinding device cannot follow the principle of "from coarse to fine" to gradually eliminate scratches and improve smoothness, and cannot eliminate deep defects of the calendering roll.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a grinding device for ferrous metal smelting rolling coils. During grinding, the grinding roller can be restricted by a limiting component to prevent it from dislodging. After coarse grinding, the limiting component can be released to use a grinding roller with a larger particle size to grind the rolling coil, thereby gradually eliminating scratches and improving the smoothness of the rolling coil.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A grinding device for ferrous metal smelting rolling coils includes a fixed plate, on both sides of which a first support plate and a second support plate are fixedly connected. A first rotating disk and a second rotating disk are rotatably connected to the first support plate and the second support plate, respectively. A plurality of grinding rollers are rotatably connected between the first rotating disk and the second rotating disk. The grit size of the plurality of grinding rollers is different. A driving component for driving the grinding rollers to rotate is provided on the first support plate, and a limiting component for limiting the rotation of the first rotating disk is provided on the first support plate.

[0008] The present invention is further configured such that: the driving assembly includes a gear one fixedly connected to the side of the grinding roller near the support plate, a plurality of positioning rods fixedly connected to the support plate, a sliding plate slidably connected to the positioning rods, a motor fixedly connected to the sliding plate, and a gear two fixedly connected to the output end of the motor. When the gear one and the gear two come into contact with each other, the gear one and the gear two mesh with each other.

[0009] The present invention is further configured such that: the limiting component includes a positioning frame fixedly connected to a rotating disk, a plurality of limiting rods slidably connected to the positioning frame, a connecting frame fixedly connected between the plurality of limiting rods, an extension plate fixedly connected to the connecting frame, and a handle rotatably connected to the extension plate; the support plate and the sliding plate are respectively provided with a through hole one and a through hole two through which the limiting rods can pass.

[0010] The present invention is further configured such that: a spring is sleeved on the positioning rod between the inner bottom side of the support plate and the sliding plate; a spring is sleeved on each of the limiting rods; and the two ends of the spring are respectively fixedly connected to the positioning frame and the connecting frame.

[0011] The present invention is further configured such that: a plurality of spring telescopic rods are fixedly connected to the fixed plate, and a positioning plate is fixedly connected to the other end of the plurality of spring telescopic rods.

[0012] The present invention is further configured such that an extension block is fixedly connected to the handle.

[0013] In summary, this utility model has the following beneficial effects: during grinding, the grinding roller can be restricted by the limiting rod to prevent the grinding roller from dislodging. After the rough grinding is completed, the limiting rod can be lifted to release the restriction on the first rotating disk. Then, the first rotating disk can be rotated to use a grinding roller with a larger particle size to grind the calendering roll. In this way, scratches can be gradually eliminated and the smoothness of the calendering roll can be improved. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] A grinding device for ferrous metal smelting rolling coils, such as Figures 1-4 As shown, the device includes a fixed plate 1, with a support plate 2 and a support plate 3 fixedly connected to both sides of the fixed plate 1. A rotating disk 4 and a rotating disk 5 are rotatably connected to the support plate 2 and the support plate 3, respectively. A plurality of grinding rollers 6 are rotatably connected between the rotating disks 4 and 5. The grit size of the grinding rollers 6 is different. The support plate 2 is provided with a drive assembly for driving the grinding rollers 6 to rotate. The support plate 2 is also provided with a limiting assembly for limiting the rotation of the rotating disk 4. The drive assembly includes a gear 7 fixedly connected to the side of the grinding roller 6 near the support plate 2, a plurality of positioning rods 8 fixedly connected to the support plate 2, a sliding plate 9 slidably connected to the positioning rods 8, a motor 10 fixedly connected to the sliding plate 9, and a gear 11 fixedly connected to the output end of the motor 10. When the gear 7 and the gear 11 come into contact with each other, the gear 7 and the gear 11 mesh with each other.

[0021] like Figures 1-4As shown, when grinding of the calender roll is required, the limiting component can be pulled to remove the limiting component from restricting the rotating disk 4. Then, the motor 10 is pressed, causing the motor 10 and gear 11 to slide downward away from the rotating disk 4, thereby preventing gear 11 from obstructing gear 10 from approaching. Then, the rotating disk 4 is rotated to drive the grinding roller 6 to rotate synchronously, so that the grinding roller 6 with the smallest particle size rotates to the working state. Then, the motor 10 is lifted, and when the motor 10 is lifted, gear 7 on the grinding roller 6 with the smallest particle size meshes with gear 11. Then, the limiting component restricts the rotating disk 4 and the sliding plate 9, so that the grinding roller 6 with the smallest particle size comes into contact with the calender roll on the upper and lower sides. Then, the calender roll is started to roll, and the motor 10 is started to drive gear 11 to rotate, which in turn drives gear 7 that meshes with it to rotate, so that the grinding roller 6 with the smallest particle size can rotate to perform coarse grinding on the calender roll.

[0022] like Figures 1-4 As shown, the limiting assembly includes a positioning frame 12 fixedly connected to the rotating disk 4, several limiting rods 13 slidably connected to the positioning frame 12, a connecting frame 14 fixedly connected between the limiting rods 13, an extension plate 15 fixedly connected to the connecting frame 14, and a handle 16 rotatably connected to the extension plate 15. The support plate 2 and the sliding plate 9 are respectively provided with through holes 17 and 18 through which the limiting rods 13 can pass. When replacing the grinding roller 6 with a larger grit size, the handle 16 can be pulled to limit the movement. The rod 13 slides on the positioning frame 12. When the limiting rod 13 slides to the point where it no longer contacts the through hole 17 and the through hole 2 18, the handle 16 can be turned to make the connecting frame 14 rotate, thereby driving the limiting rod 13, the positioning frame 12 and the rotating disk 4 to rotate. The larger grit grinding roller 6 can be replaced. When the larger grit grinding roller 6 rotates to the working state, the limiting rod 13 can be pushed so that the limiting rod 13 is placed in the through hole 17 and the through hole 2 18, which can restrict the rotating disk 4 and the sliding plate 9.

[0023] like Figures 1-4As shown, a spring 19 is sleeved between the inner bottom side of the support plate 1-2 and the sliding plate 9. When the motor 10 is pressed, the sliding plate 9 slides on the positioning rod 8, at which point the spring is compressed. The rotating disk 1-4 can then be rotated to replace the grinding roller 6. After replacement, the motor 10 is released, and it moves upward to return to its working state due to the spring 19 resetting. If the adjacent gear 1-7 and gear 2-11 are not yet engaged, rotating the adjacent gear 1-7 will engage the gear 1-7 and gear 2-11. This eliminates the need to manually lift the motor 10. Several limit rods 13 are fitted with springs 20. The two ends of the springs 20 are fixedly connected to the positioning frame 12 and the connecting frame 14, respectively. When the handle 16 is pulled to make the limit rod 13 slide on the positioning frame 12, the springs 20 will be stretched. Then, after rotating the grinding roller 6 to the working state, the handle 16 is released, and the springs 20 will reset, causing the limit rod 13 to be placed into the through hole 17 and the through hole 28, thus restricting the rotating disk 4 and the sliding plate 9.

[0024] like Figure 2 As shown, a number of spring telescopic rods 21 are fixedly connected to the fixed plate 1, and a positioning plate 22 is fixedly connected to the other end of the spring telescopic rods 21. The positioning plate 22 can be installed on the external fixed fixture, and then the external fixed fixture can be detachably connected to the calendering roll, so that the grinding roller 6 is in contact with the calendering roll on the upper and lower sides. At this time, the spring telescopic rods 21 will continuously push the fixed plate 1, so that the grinding roller 6 is always in contact with the calendering roll when it is in working state.

[0025] like Figures 1-4 As shown, an extension block 23 is fixedly connected to the handle 16, which makes it more convenient to pull the handle 16.

[0026] Working Principle: When grinding the calender roll, first pull handle 16 to slide the limiting rod 13 on the positioning frame 12. When the limiting rod 13 slides until it no longer contacts the through hole 17 and through hole 18, the limiting rod 13 will no longer restrict the rotating disk 4. At this time, the spring 20 is in a stretched state. Then press the motor 10, causing the motor 10 and gear 2 11 to slide downwards away from the rotating disk 4. The spring 19 is in a compressed state. Then turn handle 16 to rotate the connecting frame 14, which in turn drives the limiting rod 13, the positioning frame 12, and the rotating disk 4 to rotate. Then the grinding roller 6 will also rotate synchronously with the rotating disk 4, so that the grinding roller 6 with the smallest particle size rotates to the working state. Then stop pressing the motor 10. The motor 10 will move upwards and return to the working state due to the reset of the spring 19. If the adjacent gear 7 and gear 11 are not yet engaged, rotate the adjacent gear 7 to engage the gear 7 and gear 11. Then release the handle 16, and the spring 20 will reset, causing the limit rod 13 to be inserted into the through hole 17 and through hole 18, restricting the rotating disk 4 and the sliding plate 9. Next, install the positioning plate 22 on the external fixed fixture and make the grinding roller 6 with the smallest particle size fit with the calendering rolls on the upper and lower sides. Then, detachably connect the external fixed fixture to the calendering roll. At this time, the grinding roller 6 fits with the calendering rolls on the upper and lower sides, and the spring telescopic rod 21 will continuously push the fixed plate 1, so that the grinding roller 6 always fits with the calendering roll in the working state. Then start the calendering roll to roll, and start the motor 10 to drive the grinding roller 6 with the smallest particle size to rotate for polishing.

[0027] After rough grinding, the handle 16 can be pulled to allow the limiting rod 13 to slide on the positioning frame 12, thus removing the restriction on the rotating disk 4. Then, press the motor 10 and rotate the handle 16 to drive the rotating disk 4 to rotate, so that the larger-grit grinding roller 6 rotates to the working state. Then, release the motor 10 to allow the gear 7 adjacent to the gear 11 to mesh with the gear 11. Then, release the handle 16 to allow the limiting rod 13 to be placed in the through hole 17 and the through hole 18 to restrict the rotating disk 4 and the sliding plate 9. Then, start the motor 10 to drive the larger-grit grinding roller 6 to rotate for further polishing and grinding work. In this way, scratches can be gradually eliminated and the smoothness of the calender roll can be improved.
