[0026] Example

[0027] like Figure 1-6 As shown, a stone processing edge polishing machine with a protective structure includes a machine tool 1. A housing 2 is fixedly connected to the edge of the upper surface of the machine tool 1. A slide rail 3 is fixedly connected to the top and bottom of the inner side of the housing 2. A slider 4 is slidably connected inside the slide rail 3. A protective door 5 is fixedly connected to the outer surface of the slider 4. A fixed seat 6 is fixedly connected to the bottom of the front of the protective door 5. A limit rod 7 is slidably connected inside the fixed seat 6. A pull ring 8 is rotatably connected to one end of the limit rod 7. A gasket 9 is fixedly connected to the bottom of the outer surface of the limit rod 7. A spring 10 is sleeved in the middle of the outer surface of the limit rod 7. Limit holes 11 are opened on both sides of the inner bottom wall of the housing 2.

[0028] In practical use, the housing 2, protective door 5, limiting rod 7, spring 10, and limiting hole 11 are configured. The housing 2 is fixed to the edge of the upper surface of the machine tool 1 and works in conjunction with the protective door 5 to prevent stone chips from flying around during processing, effectively protecting the safety of the workers. Tempered glass is installed in the center of the front of the protective door 5, allowing workers to easily observe the edge polishing of the stone inside the device from the outside. The protective door 5 slides inside the slide rail 3 via the slider 4, making its movement smoother and more flexible. To open the protective door 5, the limiting rod 7 is moved upward using the pull ring 8, compressing the spring 10 and pushing the protective door 5 to slide to both sides. At this time, the bottom end of the limiting rod 7 makes frictional contact with the inner bottom wall of the housing 2. To close the protective door 5, the two sets of protective doors 5 are moved towards the center. Under the action of the spring 10 and the washer 9, the limiting rod 7 is inserted into the limiting hole 11, completing the quick return and relocking of the protective door 5. The operation is simple, efficient, and fast.

[0029] In this embodiment, rubber pads 12 are fixedly connected to the inner sides of both the housing 2 and the protective door 5, and anti-collision strips 13 are fixedly connected to both sides of the outer surface of the protective door 5.

[0030] In practical use, the rubber pad 12 and the anti-collision strip 13 are designed so that when the stone is polished, the flying debris will not collide with the shell 2 and the protective door 5, which will not easily generate noise and will prevent the outer skin of the shell 2 from being scratched and causing internal rust. The anti-collision strip 13 provides a buffer force when the protective door 5 is closed or fully opened, preventing damage caused by excessive force when opening and closing the protective door 5 and increasing its service life.

[0031] In this embodiment, material grooves 14 are provided on both sides of the outer surface of the housing 2, and support rods 15 are fixedly connected to both sides of the outer surface of the machine tool 1. A baffle 16 is rotatably connected to the outer surface of the support rods 15.

[0032] In practical use, the baffle 16 is set up and the support rod 15 supports the baffle 16, making it easier to open and close the baffle 16. When the baffle 16 is opened, the stone can be easily put in and taken out through the material trough 14.

[0033] In this embodiment, a magnetic strip 17 is fixedly connected to the top of the inner side of the baffle 16, and a handle 18 is fixedly connected to the top of the outer surface of the baffle 16.

[0034] In practical use, the magnetic strip 17 is fixed to the top of the inner side of the baffle 16. When the baffle 16 is closed, it can be fixed, which improves stability. The handle 18 makes it easy to control the baffle 16 and makes it easy to apply force with your hand.

[0035] In this embodiment, a conveying roller 19 is rotatably connected to the top of the inner side of the machine tool 1. There are several conveying rollers 19, which are rotatably connected to the top of the inner side of the machine tool 1 in a horizontal array.

[0036] In practical use, through the setting of conveyor rollers 19, multiple conveyor rollers 19 are evenly rotated and connected to the top of the inner side of the machine tool 1 in a horizontal array. After being connected to the drive equipment, the stone can be conveyed to achieve the purpose of automatic conveying, prevent accidents caused by manual pushing, and increase the safety of use.

[0037] In this embodiment, a fixing plate 20 is fixedly connected to the middle of the inner side of the housing 2, a cylinder 21 is fixedly connected to the upper surface of the fixing plate 20, a bracket 22 is fixedly connected to the output end of the cylinder 21, and a pressure roller 23 is rotatably connected to the inner side of the bracket 22.

[0038] In practical use, the cylinder 21 and the pressure roller 23 are set up, and the fixed plate 20 supports and fixes the cylinder 21. The output end of the cylinder 21 extends and retracts, and the pressure roller 23 can be moved by the bracket 22. It is suitable for use with stones of different thicknesses within a certain range. While ensuring the stone is conveyed, the pressure roller 23 can press the stone to prevent the stone from shifting during the edge polishing process and ensure the quality of the edge polishing.

[0039] In this embodiment, a first motor 24 is fixedly connected to the top of the inner side of the machine tool 1, a bidirectional screw 25 is fixedly connected to the output end of the first motor 24, a slide plate 26 is threadedly connected to the outer surface of the bidirectional screw 25, and a support base 27 is fixedly connected to the upper surface of the slide plate 26.

[0040] In practical use, the first motor 24 drives the bidirectional screw 25 to rotate, which causes the slide plate 26 on its outer surface to move the support base 27, thereby adjusting the position and spacing of the grinding disc 29. This is suitable for polishing the edges of stones of different widths within a certain range, and meets the processing needs of various specifications of stones.

[0041] In this embodiment, a second motor 28 is fixedly connected to the outer surface of the support base 27, and a grinding disc 29 is fixedly connected to the output end of the second motor 28.

[0042] In practical use, by setting up multiple sets of grinding discs 29 relative to each other, the second motor 28 drives the grinding discs 29 to rotate, which can polish both sides of the stone at the same time, saving time and effort and improving the efficiency of stone processing.

[0043] Working principle: In use, the baffle 16 is opened using the handle 18, and the stone is picked up and put in through the material trough 14. Multiple conveying rollers 19 convey the stone. The output end of the cylinder 21 extends, and the pressure roller 23 is driven by the bracket 22 to press and convey the stone. The first motor 24 drives the bidirectional screw 25 to rotate, causing the slide plate 26 to move the support base 27, adjusting the position and spacing of the grinding discs 29. Multiple sets of grinding discs 29 are arranged opposite each other. The second motor 28 drives the grinding discs 29 to rotate, and at the same time, the two sides of the stone are polished. The housing 2 and the protective door 5 prevent the stone from splashing randomly during processing. The rubber pad 12 prevents the flying debris from colliding with the housing 2 and the protective door 5 during edge polishing, reducing noise and preventing damage. The outer skin is scratched, causing internal rust. The protective door 5 slides smoothly and steadily inside the slide rail 3 via the slider 4. When the protective door 5 needs to be opened, the pull ring 8 is used to move the limit rod 7 upward, compressing the spring 10, which pushes the protective door 5 to slide to both sides. At this time, the bottom end of the limit rod 7 makes frictional contact with the inner bottom wall of the housing 2. When the protective door 5 needs to be closed, the two sets of protective doors 5 are moved to the middle. Under the action of the spring 10 and the washer 9, the limit rod 7 is inserted into the limit hole 11, completing the quick return and relocking of the protective door 5. The anti-collision strip 13 provides a buffer force when the protective door 5 is closed or fully opened, preventing damage caused by excessive force when opening and closing the protective door 5, and increasing its service life.
