[0018] Compared with the prior art, the present invention has the following advantages:

[0030] The present invention will be further described below in conjunction with the accompanying drawings:

[0031] like Figures 1 to 5 The grinding equipment shown includes a frame 1, within which a housing 2 and a control system 3 are housed. The housing 2 is provided with a feed inlet 21 and a discharge outlet 22 on its front and rear sides, respectively. A thickness measuring device 4 is provided inside the feed inlet 21 for measuring the thickness of the incoming plate. A grinding mechanism 5 is provided within the housing 2, which automatically adjusts the grinding gap according to the plate thickness. A conveying mechanism 6 is provided within the housing 2 for conveying the plate to be ground from the thickness measuring device 4 to the grinding mechanism 5, and for conveying the ground plate from the grinding mechanism 5 to the discharge outlet 22. The control system 3 is used to control the operation of the thickness measuring device 4, the grinding mechanism 5, and the conveying mechanism 6. The housing 2 is also provided with a water spraying device and a sewage collection device.

[0032] When the plate enters the feed port 21, the plate's thickness is measured by the thickness gauge 4 and fed back to the control system 3. The control system 3 then controls the grinding mechanism 5 to adjust the grinding process to the appropriate thickness of the plate, simplifying production operations. The grinding process takes place within a closed chamber, where dust is removed and reduced by a water spray device. The wastewater is then collected by a wastewater collection device, preventing dust pollution and ensuring a safe and hygienic working environment.

[0033] like Figure 3 and Figure 4In the illustrated embodiment, the thickness measuring device 4 includes a lower support frame 41 and an upper support frame 42 fixed to the housing 2. Horizontal correction wheels 43 of equal height are arranged side by side on the lower support frame 41. A pressing wheel 44 is slidably connected to the upper support frame 42, capable of pressing downward against the horizontal correction wheel 43 to flatten the plate. When a plate is inserted between the horizontal correction wheel 43 and the pressing wheel 44, the plate pushes the pressing wheel 44 upward. Several groups of photoelectric sensors 45 are located between the lower support frame 41 and the upper support frame 42 to sense whether the plate has entered between the horizontal correction wheel 43 and the pressing wheel 44. Lasers 46 capable of emitting and receiving laser signals are also located on the lower support frame 41 and the upper support frame 42. Multiple groups of these lasers 46 are provided to measure the plate thickness at multiple points. When no plate is placed, the distance between the upper laser and the lower laser is S. When the plate is placed for measurement, the laser hits the plate and then returns. The upper laser transmits and receives laser signals, and the distance S1 from the upper laser to the plate is calculated. The lower laser transmits and receives laser signals, and the distance S2 from the lower laser to the plate is calculated. The thickness of the plate is obtained by S-S1-S2.

[0034] The pressing wheel 44 is connected to the upper support frame 42 through a linear bearing and moves downward due to gravity. When the plate is placed between the horizontal correction wheel 43 and the pressing wheel 44, the plate pushes the pressing wheel 44 upward, and the horizontal correction wheel 43 and the pressing wheel 44 press the plate from the upper and lower sides to flatten the plate, thereby improving the measurement accuracy of the plate thickness.

[0035] like Figure 4 In the illustrated embodiment, the grinding mechanism 5 includes a lower grinding mechanism 501 and an upper grinding mechanism 502 arranged in a front-to-rear manner. The upper grinding mechanism 502 and the lower grinding mechanism 501 respectively include a grinding wheel 51 and a reference wheel 52. The grinding wheel 51 is connected to a lifting device for driving the grinding wheel 51 to move up and down, a traverse device for driving the grinding wheel 51 to move left and right, and a high-speed rotating motor 53 for driving the grinding wheel 51 to rotate at high speed. The grinding wheel 51 of the upper grinding mechanism 502 is located above the reference wheel 52, while the grinding wheel 51 of the lower grinding mechanism 501 is located below the reference wheel 52. The lower grinding mechanism 501 and the upper grinding mechanism 502 respectively grind the upper and lower surfaces of the plate, thereby improving grinding efficiency and grinding precision.

[0036] Specifically, the lifting device includes a first base 54, a second base 55 and a bearing fixing seat 56 arranged on the left and right sides of the box body 2, and the left and right ends of the grinding wheel 51 are installed on the bearing fixing seats 56 on the left and right sides. The bearing fixing seat 56 on each side is respectively connected to the second base 55 on the corresponding side for sliding left and right, and the second base 55 on each side is respectively connected to the first base 54 on the corresponding side for moving up and down. The lifting device also includes a turbine screw lifter 57 for driving the second base 55 to move up and down relative to the first base 54 and a lifting motor 58 for driving the turbine screw lifter 57 to work. The transverse movement device includes a transverse movement drive motor 59 arranged on the second base 55 on one side, and a camshaft 510 is connected to the output end of the transverse movement drive motor 59. A connecting shaft 511 is provided between the camshaft 510 and the bearing fixing seat 56 on the corresponding side. When the camshaft 510 rotates, the bearing fixing seat 56 is driven to slide left and right through the connecting shaft 511.

[0037] Control system 3 controls the lifting motor 58 to precisely adjust the height of the grinding wheel 51 relative to the reference wheel 52, effectively adapting to the grinding of plates of varying thicknesses. During grinding, the plate is inserted between the reference wheel and the grinding wheel, and the reference wheel moves with the grinding wheel. Furthermore, a transverse mechanism allows the grinding wheel to move left and right during the grinding process, ensuring more uniform grinding of the plate.

[0038] like Figure 3 In the embodiment shown, there are two worm screw lifts 57 on the left and right, and the two worm screw lifts 57 on the left and right are connected by a coupling 512 to allow the two to work synchronously. There is one lifting motor 58 and it drives the two worm screw lifts 57 to work simultaneously. It has a simple structure and is easy to control. It also makes the lifting heights of the left and right ends of the grinding wheel consistent, avoiding the situation where one side is higher than the other side and affects the uniformity of grinding.

[0039] The plate enters the grinding space through the side thickness space where the thickness measuring device is located, and first enters the lower grinding mechanism. The left and right bearing seats corresponding to the grinding wheels of the lower grinding mechanism are locked on the bearing fixing seat by the reverse teeth. The transverse drive motor and the high-speed rotary motor run simultaneously. The lifting motor 58 drives the turbine screw lift 57 connected at both ends to adjust up and down synchronously to control the spacing between the grinding wheel and the reference wheel to perform grinding operations for plates of different thicknesses. When the transverse drive motor drives the camshaft to rotate, the connecting shaft drives the bearing fixing seat to slide left and right to realize the left and right movement of the grinding wheel, so that the plate is ground more evenly. The present invention can also select the speed of the high-speed rotary motor according to the material of different plate materials to achieve different surface grinding effects.

[0040] like Figure 4In the embodiment shown, the conveying mechanism 6 includes several groups of conveying rollers, and the conveying rollers include a power wheel 61 and a pressure wheel 62. The power wheel 61 is rotatably connected to the box body 2 and has a fixed height. A conveying drive device for driving the power wheel 61 to rotate is provided on the frame 1. Preferably, as shown in FIG. Figures 2 to 4 As shown, the conveying drive device adopts a motor, sprocket and chain structure, the pressure wheel 62 is rotatably connected to the mounting seat 63, the mounting seat 63 is slidably connected to the box body 2, and is pressed toward one side of the power wheel 61 through the pressure spring 64. When the power wheel 61 and the pressure wheel 62 are squeezed into the plate, the plate overcomes the elastic force of the pressure spring 64 to push the pressure wheel 62 up and down, and the plate is elastically squeezed by the power wheel 61 and the pressure wheel 62, and the plate is conveyed and moved during rotation.

[0041] In order to prevent slipping, the power wheel 61 and the pressure wheel 62 are formed by a stainless steel shaft with polyurethane wrapped on the outside. The polyurethane is squeezed on the plate to overcome the reaction of the plate during the grinding process.

[0042] like Figure 4 In the embodiment shown, a water squeezing mechanism 9 is provided in the box body 2 at the rear side of the grinding mechanism 5 , and the water squeezing mechanism 9 is used to scrape off water droplets on the plate after grinding, so as to facilitate the drying of the plate.

[0043] The water squeezing mechanism 9 includes a plurality of water squeezing roller groups consisting of two water squeezing wheels 91 facing each other. The water squeezing wheels 91 are formed by a stainless steel shaft with a sponge layer on the outside. The conveying mechanism drives the plate to move. The water squeezing wheels 91 squeeze the plate from the top and bottom, scraping off water droplets on the surface of the plate. The sponge layer is conducive to absorbing water and squeezing water. Because the sponge is easy to deform, it can accommodate plates of different thicknesses within a certain thickness range. The upper and lower water squeezing wheels 91 are respectively rotatably connected to an adjustment seat 92. The adjustment seat 92 is slidably connected to the box body 2. The box body 2 is provided with a height adjustment assembly for adjusting the height of the upper and lower adjustment seats 92 respectively. The height adjustment assembly includes a threaded connecting rod, wherein the upper connecting rod is rotatably connected to the box body 2 and is threadedly connected to the upper adjustment seat 92, while the lower connecting rod is threadedly connected to the box body 2 and supports the lower adjustment seat 92 from bottom to top through the connecting rod. When the thickness of the plate and the gap between the upper and lower water squeezing wheels 91 differ too much, the height of the adjustment seat 92 is adjusted by the height adjustment assembly to adjust the distance between the upper and lower water squeezing wheels 91 so as to better allow the plate to pass through and remove water.

[0044] like Figure 1 and Figure 4In the illustrated embodiment, the water spray device includes a high-pressure water spray pipe 71. A water pump 72 is provided on the outside of the housing 2 for supplying high-pressure water to the high-pressure water spray pipe 71. To facilitate cleaning the surface of the grinding plate, the high-pressure water spray pipes 71 are provided in pairs, one above the other, and are arranged parallel to each other in front of the grinding wheels of the upper grinding mechanism 502 and the lower grinding mechanism 501, respectively, to spray water on the plate.

[0045] The sewage collection device includes a water tank 81 for collecting sewage discharged from the bottom of the housing 2 and an oil collection trough 82 for collecting water stains and lubricating oil dripping from the left and right sides of the exterior of the housing 2. A water guide plate is installed at an angle at the bottom of the housing, with the guide plate located at a higher height on the front side of the grinding mechanism than on the rear side. The water tank is located directly below the rear end of the housing. Grinding clean water and water droplets scraped by the water wheel flow into the bottom of the housing. The guide plate guides the sewage to the drain outlet at the rear end of the housing and then into the water tank. The water tank is equipped with a filter screen to filter out large particles such as copper foil and residual rubber. After the sewage passes through the filter screen for primary filtration, it is then filtered again by a high-pressure bag filter cartridge connected to the water tank. The bag filter cartridge allows water to pass through while blocking particulate matter such as dust. The filtered water is connected to a water pump via a water pipe and supplied to the high-pressure water spray pipe by the water pump for a second cleaning cycle.
