[0002] Composite polystyrene sheets are typically thicker and belong to the board material category. They have good rigidity, thermal insulation, and impact resistance. Common composite polystyrene sheets include thermosetting polystyrene boards (TEPS). These boards are made through processes such as particle coating, mixing molding, or substrate infiltration, and have shape retention and anti-melt dripping properties.
[0003] After the production of composite polystyrene sheets, the edges of the sheets may have burrs, parting lines, or uneven cuts, requiring edge grinding to ensure smooth edges. Currently, grinding requires workers to hand-grind the edges of the sheets with a grinding device. Even when using a grinding machine for mechanical grinding, manual switching of the grinding edge is still necessary, which consumes a lot of manpower, is inefficient, and produces flying debris that affects the environment.

[0023] Reference Figure 2 As shown, a dust extraction hole 111 is provided at the top of the workbench 1 corresponding to the grinding unit 10. Two filters 222 are connected to the inner wall of the workbench 1. A negative pressure fan 17 is located between the filters 222. When the negative pressure fan 17 is working, it draws air from the workbench 1, thereby drawing the debris from the grinding unit 10 into the workbench 1 through the dust extraction hole 111. The filters 222 can block dust from accumulating inside the workbench 1. A sealed door (not shown) is provided on one side of the workbench 1 for cleaning the debris collected inside.
[0024] Reference Figure 1 and Figure 2 As shown, a guide rod 22 is connected to the top of the card holder 20. One end of the guide rod 22 is slidably connected to the protective cover 18. Observation windows 181 are provided on both sides of the protective cover 18. The guide rod 22 can ensure the stability when 19 pushes 20 to move. The polishing condition can be detected through the observation window 181.
[0025] Reference Figure 2 As shown, the conveying mechanism includes a side plate 2 fixed to the top of the workbench 1. Two sets of support rollers 3 are rotatably arranged on the side of the side plate 2 that are close to each other, with a gap left at the position corresponding to the lifting unit 16. Conveyor belts 4 are sleeved and connected to both ends of the support rollers 3. One end of one set of support rollers 3 is connected to a drive motor 5. The conveyor belts 4 are located on both sides of the support rollers 3. When the sheet moves above the lifting unit 16 with the conveying unit, the lifting unit 16 can perform positioning, rotation and resetting of the sheet through the conveyor belts 4. The drive motor 5 drives the support rollers 3 located at the ends to rotate, thereby driving the conveyor belts 4 to run. The support rollers 3 in the middle part can support the conveyor belts 4 during grinding to ensure grinding stability.
[0026] Reference Figure 5 As shown, the grinding unit 10 includes an L-shaped frame 101 connected to both ends of the bottom support plate 7 and the top support plate 9. Two guide rollers 102 are rotatably mounted on the outer side of each L-shaped frame 101. A grinding belt 103 is sleeved and connected between the guide rollers 102. A drive motor 104 is connected to one end of each guide roller 102. A guide frame 105 is connected to the top of the lower L-shaped frame 101, and the guide frame 105 is slidably connected to the upper L-shaped frame 101. The shape of the L-shaped frame 101 allows for... The two adjacent sanding belts 103 are both vertically arranged, forming a vertical angle, which can accurately sand the edge of the sheet. By adjusting the cylinder 8, the top support plate 9 is pushed, which drives the L-shaped frame 101 located above to move along the guide frame 105, which can meet the sanding of sheets of different thicknesses. The pushing of the extrusion cylinder 23 can ensure the fit between the sanding unit 10 and the edge of the sheet, ensuring the sanding effect. At the same time, a controller is connected to one side of 1 to control the extension and retraction of the extrusion cylinder 23 and the adjusting cylinder 8.
[0027] Reference Figure 4 As shown, the edge-changing mechanism includes an internal frame 12 located at the output end of the lifting cylinder 11. The internal frame 12 is slidably connected to the worktable 1, and an installation frame 13 is connected to its inner side. A rotary cylinder 14 is connected to the top of the installation frame 13, and a connecting seat 15 is connected to the output end of the rotary cylinder 14. A lifting unit 16 is connected to the top of the connecting seat 15. The lifting cylinder 11 extends and pushes the internal frame 12 to move upward. The installation frame 13 drives the rotary cylinder 14 to move upward together, thereby lifting the sheet material located above by the lifting unit 16. Then, the rotary cylinder 14 drives the lifting unit 16 to rotate 90 degrees to change the edge. Then, the sheet material moves downward and is placed on the conveyor belt 4 to enter the next set of grinding units 10 for grinding.
[0028] Reference Figure 6As shown, the lifting unit 16 includes a bracket 161 fixedly mounted on the top of the connecting seat 15. Air intake slots 162 are provided at the four corners of the top of the bracket 161. Air pipes 163 are connected to the bottom of the bracket 161 corresponding to the air intake slots 162. Branch pipes 164 are connected between the air pipes 163. An external connecting pipe 165 is connected to one side of each air pipe 163. The other end of the external connecting pipe 165 is connected to an external air source. Since this is a standard configuration, it is not described in detail in the manual. It can also be seen from the attached drawings that a pressure relief valve is connected to the end of the external connecting pipe 165. For venting and depressurizing the sheet, the top of the bracket 161 has multiple mounting slots, and each mounting slot is connected to an infrared sensor 166. When the sheet moves above the bracket 161 with the conveyor belt 4, the infrared sensor 166 can detect the movement position. When all the infrared sensors 166 detect the sheet, the switching mechanism is driven to lift the bracket 161. At the same time, the external air source is started, and air is drawn from the suction slot 162 through the air pipe 163 and the branch pipe 164, thereby adsorbing and fixing the sheet to ensure the stability of the switching.
[0029] The implementation principle of this application is as follows: When using this utility model, the sheet to be polished is placed on the conveying mechanism. As the conveying mechanism drives the sheet, it moves between the two polishing units 10 located at the front end. The conveying mechanism stops, and the pressing cylinder 19 extends to push the clamp 20 downward, thereby driving the pressing roller 21 to press against the top surface of the sheet. The spacing between the two sets of polishing units 10 located on the same side is adjusted by the adjusting cylinder 8 pushing the top support plate 9. The squeezing cylinder 23 pushes the polishing unit 10 to clamp against the edge of the sheet. Then, the drive motor 104 drives the guide roller 102 to rotate, thereby driving the polishing unit 10 to rotate. The abrasive belt 103 operates to polish the edges of the sheet. After polishing, the pressing cylinder 19 and the squeezing cylinder 23 retract, separating the polishing unit 10 from the sheet. The conveying mechanism starts, moving the sheet above the lifting unit 16. The conveying mechanism stops again, and the edge-changing mechanism starts, rotating the sheet 90 degrees to change its edge. The sheet is then placed back on the conveying mechanism, which starts again to polish the edges of the changed sheet. During polishing, the negative pressure fan 17 can suck the debris generated during polishing into the workbench 1 through the dust extraction hole 111 for collection, reducing the impact on the environment.
