Description

Technical Field

[0001] This utility model relates to the technical field of steel grinding devices, and in particular to a strip steel surface grinding device for strip steel production. Background Technology

[0002] During the strip steel production process, the strip steel surface often suffers from a series of defects such as oxide scale, burrs, and scratches due to rolling and transportation, which affect the quality of subsequent processing. Traditional grinding methods have problems such as low efficiency, poor grinding uniformity, high labor costs, and serious dust pollution. Moreover, they are difficult to adapt to high-speed continuous strip steel production lines. With the increasing demand for automation and high precision in strip steel production, a special device that can adapt to the production line speed, achieve uniform grinding, reduce manual intervention, and take into account environmental protection is needed.

[0003] In the modern strip steel production field, the surface quality of strip steel directly affects its application effect in downstream industries such as automobile manufacturing and home appliance production. Traditional strip steel surface grinding equipment mainly removes surface oxide scale and burr defects through mechanical grinding. However, in actual production, the large amount of metal dust generated during the grinding process can easily cause environmental pollution, and inhalation can harm the health of operators. Although existing dust collection structures can collect some dust, they are difficult to completely eliminate dust, resulting in reduced production safety and practicality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a strip steel surface grinding device for strip steel production, which aims to improve the problem that although the dust collection structure of the existing strip steel surface grinding device can collect some dust, it is difficult to completely eliminate the dust phenomenon, resulting in reduced production safety and reduced practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a strip steel surface grinding device for strip steel production, comprising a trapezoidal cover plate, a top plate being snapped into the bottom of the trapezoidal cover plate, a handrail being fixedly connected to the left side of the top plate, multiple support columns being fixedly connected to the bottom of the top plate, universal wheels being fixedly connected to the bottom of the support columns, a left side plate being fixedly connected to the left side of the top plate, a hollow tube being fixedly connected to the left side of the left side plate, a bottom plate being fixedly connected to the bottom of the left side plate, a support plate being fixedly connected to the inner side of the bottom plate, a rear side plate being fixedly connected to the rear side of the bottom plate, a water tank being fixedly connected to the front side of the bottom plate, a water pump being connected to the left side of the inner wall of the water tank, a magnetic strip being fixedly connected to the bottom end of the bottom plate, a right side plate being fixedly connected to the right side of the bottom plate, and a positioning adjustment mechanism being fixedly connected to the middle of the inner wall of the right side plate, the positioning adjustment mechanism being used to adapt to materials of different sizes.

The top of the fixing block has multiple pin holes, and the inner wall of the pin holes is slidably connected to a fixing pin. The outer wall of the fixing pin is provided with a positioning block. A cylindrical block is fixedly connected to each adjacent side of the multiple positioning blocks. The outer wall of the cylindrical block is provided with a hollow block. The inner wall of the multiple hollow blocks is fixedly connected to a spring, and the outer wall of the multiple hollow blocks is fixedly connected to a bearing.

[0008] As a further description of the above technical solution:

[0009] A servo motor is fixedly connected to the bottom of the top plate, and a drive gear is fixedly connected to the output end of the servo motor.

[0010] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, iron filings and dust generated from grinding the surface of the steel strip are flushed down by water pump from the lower water tank. Before flowing into the water tank, the iron filings are attracted by the magnetic strip, and the water flows back into the water tank. This cycle is repeated. This device can effectively improve the phenomenon that iron filings and dust are difficult to clean and easy to generate dust, making it convenient for workers to clean the device regularly. It also greatly reduces the harm of workers inhaling dust during operation and ensures safe production.

[0022] 2. In this invention, an auxiliary positioning and adjustable size device is added to the grinding area, allowing the device to adapt to a wider range of strip sizes. The strip edge is connected to a rolling bearing, reducing scraping wear on the strip edge. Small adjustments can be made via a spring, while large adjustments can be made by changing the position of the positioning block on the fixed block to scale the size. This device effectively reduces the frequency of mold changes when grinding strips of different sizes, significantly improving work efficiency. Attached Figure Description

[0037] Specifically, a servo motor 6 is fixedly connected to the bottom of the top plate 3. The output end of the motor is connected to a drive gear 25. The inner wall of the drive gear 25 is meshed with the transmission belt 16. When the servo motor 6 is turned on, it drives the transmission belt 16 to work. The transmission belt 16 is also meshed with the driven gear 26, so the driven gear 26 on the right side also starts to rotate.

[0038] Please see the appendix Figure 3 and attached Figure 6 A transmission rod 19 is fixedly connected to the inner wall of the driven gear 26. A conveying roller 17 is fixedly connected to the right end of the transmission rod 19. A driven gear 20 is meshed with the outer wall of the drive gear 25 near the edge.

An observation window 13 is fixedly connected to the front side of the front side plate 4.

[0039] Specifically, the driven gear 26 on the right rotates and drives the conveying roller 17 connected to the right end of the rod to rotate via the transmission rod 19, thereby conveying the strip steel; the drive gear 25 rotates and drives the driven gear 26 above to rotate via the two driven gears 20, and the driven gear 26 above drives the grinding roller 18 connected to the right end of the rod to rotate via the transmission rod 21, thereby grinding the strip steel. There is an observation window 13 on the front side plate 4 above the water tank 24 to observe the internal structure.

[0040] Working principle: When the strip steel is being ground, the grinding roller 18 generates a large amount of metal filings and dust. At this time, the water pump 22 is started. The water pump 22 draws water from the water tank 24. The water is drawn in through the lower port of the hollow tube 8 and then sprayed out from the other port, washing away the steel filings and dust from the ground strip. The filings flow down the inclined base plate 14 with the water flow and are then attracted by the magnetic strip 23. The water flow returns to the water tank 24.

[0041] To accommodate strips of different sizes being fed into the machine for grinding, positioning and adjusting clamps are installed before and after the grinding roller 18 to fix the strips of different sizes. The input strip is supported by the hollow block 206, and the bearings 205 on both sides block the strip to prevent it from shifting. The iron ring on the outside of the bearing 205 rolls to prevent damage to the strip. Small-size adjustments can be made by the spring 204, while large-size width adjustments can be made by changing the position of the through hole of the fixing pin 201 to adjust the position of the fixing block 203 and the positioning block 202.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
