[0002] In the production process of PVC boards, a trimming device is needed to trim the edges of the finished product. During the trimming process, it is often necessary to grind and trim the four sides of the PVC board to achieve the purpose of effective trimming.
[0003] Since the four sides of the PVC board are irregular, the current trimming device is not convenient for fine grinding the burrs of the PVC board during trimming, and burrs are easily generated on the PVC board during the trimming process, and the edges of the PVC board cannot be effectively trimmed, resulting in poor effect of the trimmed PVC board. Utility Model Content
[0004] In order to overcome the above shortcomings, the present invention provides a PVC board finished edge trimming device, which can grind and polish the four edges of the PVC board to prevent burrs from forming on the edges of the PVC board and can repeatedly scrape off the burrs of the PVC board, thereby further enhancing the trimming effect.
[0005] The technical solution is as follows: A device for trimming the edge of a finished PVC board comprises a base plate, the base plate is rotatably connected to a rotating column, the rotating column is fixedly connected to an overrunning clutch, the outer side of the overrunning clutch is fixedly connected to a trackless cylinder, the base plate is fixedly connected to a slide block slidably connected to the trackless cylinder, the bottom of the slide block is fixedly connected to a rack, the rack is meshed with the gear, the slide block is fixedly connected to a fixed frame, the fixed frame is fixedly connected to a motor, the output shaft of the motor is fixedly connected to a transmission rod, the transmission rod passes through the fixed frame, the transmission rod is fixedly connected to a grinding wheel, the trackless cylinder is fixedly connected to a connecting frame, the connecting frame is threadedly connected to a screw, the bottom of the screw is rotatably connected to a pressure plate, the fixed frame is provided with a grinding assembly, the grinding assembly is connected to the transmission rod, the transmission rod is provided with a scraping assembly, the scraping assembly is connected to the fixed frame, the grinding assembly is used to grind the edge of the PVC board, and the scraping assembly is used to scrape off edge burrs.
[0006] Furthermore, the grinding assembly includes a grinding wheel, which is rotatably connected to the fixed frame. The grinding wheel and the bottom of the transmission rod are respectively fixedly connected with sprockets, and a chain is wound between the two sprockets.
[0007] Furthermore, the grinding wheel is provided with a plurality of protrusions.
[0008] Furthermore, the scraping assembly includes a cam, two of the cams are fixedly connected to the transmission rod and the top of the grinding wheel respectively, two scrapers are fixedly connected to the fixed frame, one side of the two scrapers is in contact with the two cams respectively, and a torsion spring is connected between the two scrapers and the fixed frame.
[0009] The beneficial effects of the utility model are as follows: 1. The slider moves through the fixed frame so that the grinding wheel grinds the edge of the PVC board. The reciprocating movement of the slider causes the rack to move reciprocatingly and drives the gear to rotate reciprocatingly. The reciprocating rotation of the gear causes the rotating column to drive the PVC board to rotate intermittently in the same direction through the overrunning clutch, thereby grinding and trimming the four sides of the PVC board, thereby improving the trimming efficiency. The rotation of the transmission rod drives the sprocket to rotate at the same time, and the rotation of the sprocket drives the grinding wheel to rotate through the chain. The grinding wheel rotates and grinds the edge of the ground and trimmed PVC board, thereby making it less likely that the edge of the PVC board will have burrs, thereby enhancing the trimming effect.
[0010] 2. The rotation of the transmission rod and the grinding wheel will cause the scraper to swing back and forth through the cam. The reciprocating swing of the scraper will scrape off the burrs on the PVC board, making the edge of the PVC board smoother, thereby improving the quality after trimming and further enhancing the trimming effect.

The specific connection methods of each part adopt conventional means such as bolts, rivets, welding, and bonding in the existing technology, which will not be described in detail here.
[0018] Example 1: A PVC board finished edge trimming device, such as Figure 1-Figure 5 As shown, it includes a base plate 1, a rotating column 2 is rotatably connected to the base plate 1, an overrunning clutch 3 is fixedly connected to the rotating column 2, a gear 4 is fixedly connected to the outside of the overrunning clutch 3, a trackless cylinder 5 is welded on the base plate 1, a slider 6 is slidably connected to the trackless cylinder 5, a rack 7 is fixedly connected to the bottom of the slider 6, a fixing frame 8 is fixedly connected to the slider 6, a motor 9 is fixedly connected to the fixing frame 8, a transmission rod 10 is provided on the output shaft of the motor 9 through a flat key, the transmission rod 10 passes through the fixing frame 8, and a grinding wheel is welded on the transmission rod 10. The cutting wheel 11 is used to grind the protrusions on the edge of the PVC board. The trackless cylinder 5 is fixedly connected to a connecting frame 12, and the connecting frame 12 is threadedly connected to a screw 13. The bottom of the screw 13 is rotatably connected to a pressure plate 14, and the pressure plate 14 is used to clamp the PVC board. The fixed frame 8 is provided with a grinding assembly, and the grinding assembly is connected to the transmission rod 10. The transmission rod 10 is provided with a scraping assembly, and the scraping assembly is connected to the fixed frame 8. The grinding assembly is used to grind the edge of the PVC board, and the scraping assembly is used to scrape off the burrs on the edge.
[0019] The grinding assembly includes a grinding wheel 15, which is rotatably connected to the fixed frame 8. The grinding wheel 15 is used to finely grind the edge of the PVC board. The grinding wheel 15 and the bottom of the transmission rod 10 are respectively fixedly connected with a sprocket 16, and a chain 17 is wound between the two sprockets 16.
[0020] The grinding wheel 15 is provided with a plurality of protrusions, and the protrusions on the grinding wheel 15 are used to better grind off burrs.
[0021] The scraping assembly includes a cam 18, and the two cams 18 are respectively fixedly connected to the transmission rod 10 and the top of the grinding wheel 15. Two scrapers 19 are fixedly connected to the fixed frame 8. One side of the two scrapers 19 is in contact with the two cams 18 respectively. The two scrapers 19 are used to scrape off burrs generated on the edge of the PVC board. A torsion spring 20 is connected between the two scrapers 19 and the fixed frame 8, and the cam 18 is used to squeeze the scraper 19.
[0022] When it is necessary to trim the edge of the finished PVC board, the staff first places the PVC board on the rotating column 2, and drives the pressing plate 14 to move downward by twisting the screw 13 to clamp the PVC board. Then, the trackless cylinder 5 and the motor 9 are started. The trackless cylinder 5 drives the slider 6 to move and drives the fixed frame 8 and the rack 7 to move at a constant speed. The rack 7 moves to drive the gear 4 to rotate. The fixed frame 8 moves at a constant speed and drives the grinding wheel 11 to move. The output shaft of the motor 9 rotates through the transmission rod 10 to drive the grinding wheel 11 to rotate. While the grinding wheel 11 rotates, the edge of the PVC board is trimmed. After grinding and dressing, the trackless cylinder 5 drives the slider 6 to move in the opposite direction so that the rack 7 and the fixed frame 8 are reset. The rack 7 is reset to drive the gear 4 to rotate in the opposite direction for a certain angle. The gear 4 is reversed and drives the rotating column 2 to rotate through the overrunning clutch 3. The rotating column 2 rotates and drives the PVC board to rotate a certain angle. Repeat this process. The slider 6 moves through the fixed frame 8 so that the grinding wheel 11 grinds the edge of the PVC board. The reciprocating movement of the slider 6 will cause the rack 7 to move back and forth and drive the gear 4 to rotate back and forth. The reciprocating rotation of the gear 4 will cause the rotating column 2 to rotate through the overrunning clutch 3. The PVC board is driven to rotate intermittently in the same direction, thereby grinding and trimming the four sides of the PVC board, thereby improving the trimming efficiency. The transmission rod 10 rotates while driving the sprocket 16 to rotate. The rotation of the sprocket 16 drives the grinding wheel 15 to rotate through the chain 17. The grinding wheel 15 rotates while grinding the edge of the PVC board after grinding and trimming, thereby making it less likely to have burrs on the edge of the PVC board, thereby enhancing the trimming effect. The rotation of the transmission rod 10 and the grinding wheel 15 drives the cam 18 to rotate. The rotation of the cam 18 squeezes the scraper 19 to rotate, and the torsion spring 20 is twisted, the cam 18 continues to rotate and disengages from the scraper 19, and the torsion spring 20 is reset to drive the scraper 19 to reset, and this is repeated. The rotation of the transmission rod 10 and the grinding wheel 15 will cause the scraper 19 to swing back and forth through the cam 18. The reciprocating swing of the scraper 19 will scrape off the burrs on the PVC board, thereby making the edge of the PVC board smoother, thereby improving the quality after trimming, thereby further enhancing the trimming effect. After the four sides of the PVC board are trimmed, turn off the trackless cylinder 5 and the motor 9, screw the screw 13 in the opposite direction, and remove the PVC board.
