Description

Technical Field

[0001] This utility model relates to the field of stainless steel strip grinding technology, and more specifically, to a stainless steel strip grinding device. Background Technology

[0002] Stainless steel strip is a long strip of metal material made from stainless steel. It has excellent corrosion resistance, mechanical properties and processing performance, and is widely used in many fields such as industry, construction, electronics, and food. The main component of stainless steel strip is iron (Fe), and alloying elements such as chromium (Cr), nickel (Ni) and molybdenum (Mo) are added to improve its corrosion resistance and mechanical properties.

[0003] During the production process of stainless steel strip, defects such as oxide layer, burrs or scratches are easily generated on the surface due to rolling and heat treatment processes, which affect product quality. In order to meet the high surface quality requirements, the steel strip usually needs to be ground. Most of the existing grinding wheels do not have the dust suppression effect when grinding stainless steel strip. The metal dust generated during the grinding process is easy to spread, pollute the environment and endanger the health of operators.

[0004] Based on this, this utility model discloses a stainless steel strip grinding device. Summary of the Invention

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] To address the issue that existing stainless steel strip production processes, such as rolling and heat treatment, can easily lead to surface defects like oxide layers, burrs, or scratches, affecting product quality, and to meet high surface quality requirements, the steel strip usually needs to be regrinded. However, most existing regrinding wheels do not have dust suppression effects when regrinding stainless steel strips, and the metal dust generated during the regrinding process is easily dispersed, polluting the environment and endangering the health of operators.

[0026] Therefore, this utility model provides a stainless steel strip grinding device, see [link / reference]. Figures 1 to 4 As shown, it includes a fixed frame 1, a dust suppression component is provided on the upper part of the fixed frame 1, and a grinding component is provided in the inner cavity of the fixed frame 1.

[0027] The grinding assembly includes a drive motor 2, which is fixedly connected to one side of a fixed frame 1. The output shaft of the drive motor 2 passes through the fixed frame 1. A grinding wheel A3 is provided in the lower part of the inner cavity of the fixed frame 1. The output of the drive motor 2 is fixedly connected to the inner cavity shaft of the grinding wheel A3. The inner cavity shaft of the grinding wheel A3 passes through the other side of the fixed frame 1. A drive gear 4 is fixedly connected to the other side of the inner shaft of the grinding wheel A3.

[0028] The upper part of the drive gear 4 is meshed with the driven gear A5. The inner cavity of the driven gear A5 is provided with a grinding wheel B6. The inner shaft of the grinding wheel B6 is fixedly connected to the inner cavity of the driven gear A5. One side of the grinding wheel B6 is movably connected to the inner wall of the fixed frame 1 through a rotating pair.

[0029] During operation, the stainless steel strip to be ground is placed between two grinding wheels A3 and B6, and the drive motor 2 is started. The output shaft of the drive motor drives the grinding wheel A3 to rotate. When the grinding wheel A3 rotates, it can synchronously drive the drive gear 4 to rotate, and the drive gear 4 drives the driven gear A5 to rotate. When the driven gear A5 rotates, it can synchronously drive the grinding wheel B6 to rotate. The grinding wheels A3 and B6 are used to evenly grind both sides of the stainless steel strip.

[0030] Further, see Figures 4 to 8 As shown, the dust suppression component includes a shielding box 7. The lower part of the shielding box 7 is fixedly connected to the upper part of the fixed frame 1. Limiting strips 8 are fixedly connected to both ends of the inner cavity of the shielding box 7. A driving block 9 is slidably connected to the opposite side of each limiting strip 8. A spraying plate 10 is fixedly connected between the opposite sides of each driving block 9. A spraying head 11 is connected to the lower part of the spraying plate 10.

[0031] Driven gear A5 is meshed with driven gear B12 at its upper part. A reciprocating screw 13 is fixedly connected to the inner cavity of driven gear B12. One side of the reciprocating screw 13 is movably connected to the inner wall of the shield box 7 through a rotating pair. Spray plate 10 is threadedly connected to reciprocating screw 13 through a threaded sleeve. A groove is provided in the upper part of the shield box. A conveying pipe 14 is connected to the upper part of the spray plate 10. The conveying pipe 14 passes through the groove on the shield box 7. A water pump 15 is connected to the lower part of the conveying pipe 14. The other end of the water pump 15 is connected to a water tank 16.

[0032] A flow channel is provided in the middle of the inner cavity of the fixed frame 1. A barrier net 17 is provided at the bottom of the fixed frame 1 at the bottom of the flow channel. Guide rails 18 are provided on both sides of the bottom of the fixed frame 1 at both sides of the barrier net 17. The two sides of the barrier net 17 are slidably connected to the guide rails 18. A collection box 19 is fixedly connected to the lower part of the barrier net 17. A drain pipe 20 is connected to one side of the collection box 19.

[0033] During operation, when grinding the stainless steel strip, the drain pipe 20 is connected to a water filter (as per existing technology), and the filtered pipe is connected to the water tank 16. The water pump 15 is started, drawing water from the water tank 16 and transporting it to the conveying pipe 14. The water is then transported to the spray plate 10 via the conveying pipe 14, and sprayed onto the dust generated during grinding by the spray plate 10 through the spray head 11. When the driven gear A5 rotates, it synchronously drives the driven gear B12 to rotate. The driven gear B12 drives the reciprocating screw 13 to rotate, which in turn drives the threaded spray plate 10 to move. The direction of movement is limited by the driving block 9 and the sliding connection limit strip 8, so that the spray plate 10 can only move in a straight line. The spray plate 10 drives the spray head 11 to reciprocate, which can comprehensively suppress the dust generated during grinding, thereby expanding the dust suppression range. The water sprayed during dust suppression flows through the filter of the barrier net 17 into the collection box 19, and is transported to the filter through the drain pipe 20 for filtration. The filtered water is then transported back to the water tank 16 for reuse. When the dust on the surface of the barrier net 17 reaches a certain amount, the barrier net 17 can be pulled out by the staff for cleaning and then reset. The water described in this technical solution is water that is compatible with the grinding process.

[0034] Among them, see Figures 1 to 4 As shown, drive cylinders 21 are fixedly connected to both ends of the fixed frame 1. The output shaft of the drive cylinder 21 passes through the fixed frame 1, and a guide frame 22 is fixedly connected to the output shaft of the drive cylinder 21.

[0035] During operation, when grinding the stainless steel strip, the drive cylinder 21 is activated. The output shaft of the drive cylinder 21 drives the guide frame 22 to move, moving the guide frame 22 to a position that matches the stainless steel strip, thereby guiding the stainless steel strip and reducing the problem of the stainless steel strip shifting during grinding. The synchronous movement of the drive cylinder 21 mentioned above is a commonly used driving method in the prior art, so it will not be explained further in this technical solution.
