Description

Technical Field

[0001] This utility model relates to the field of plastic sheet production technology, and in particular to a splash-proof structure for a plastic sheet grinding device. Background Technology

[0002] Plastic sheets are flat plastic products made from various polymer materials through processes such as extrusion, calendering, or injection molding. Due to their lightweight, durability, and high plasticity, they are widely used in industries such as construction, packaging, and medical fields. During the production process, the edges and burrs of plastic sheets need to be polished.

[0003] Most current plastic sheet grinding devices have relatively simple structures. The waste generated during grinding will fly everywhere. The waste is small in size and may be scattered in various corners of the workbench, polluting the working environment. In addition, the waste often forms static electricity, making it difficult to clean.

[0004] Therefore, in view of the problem that waste chips fly everywhere and pollute the working environment when existing plastic sheet grinding devices are used, a splash-proof structure for plastic sheet grinding devices can be designed. By using closed grinding and negative pressure suction, waste chips can be effectively prevented from flying everywhere, and residual waste chips that are statically attached to the device can be sucked up in time, reducing the difficulty of subsequent cleaning operations and thus enhancing the practical value of the device. Utility Model Content

[0005] In order to overcome the problems of most plastic sheet grinding devices, which produce waste chips that fly everywhere during grinding and may scatter in various corners of the workbench, polluting the working environment, and the waste chips often form static electricity, making cleaning difficult, this utility model is proposed.

[0006] The technical solution of this utility model is as follows: a splash-proof structure for a plastic sheet grinding device, comprising a worktable, a control console, a fixed frame, a sheet body, a grinding roller, a telescopic rod, a protective cover, a negative pressure pipe, a telescopic pipe, a waste bin, a drive gear, a driven gear, an upper scraper, and a side scraper. The upper surface of the worktable is equipped with a control console, and the upper surface of the worktable is equipped with a fixed frame. The sheet body is located on one side of the fixed frame, and the grinding roller is located on one side of the sheet body. The upper surface of the worktable is equipped with a telescopic rod, and one end of the telescopic rod is equipped with a protective cover.

The inner side of the protective cover is equipped with an upper scraper, and one end of the upper scraper is equipped with a side scraper.

[0007] Preferably, a workbench support frame is set up, on which the sheet to be ground is placed. Grinding rollers rotate to grind both sides of the sheet. A telescopic command is sent from the control console to the telescopic rod, causing the telescopic rod to extend and retract, raising and lowering the protective cover. The protective cover seals the support frame inside, preventing waste from flying everywhere. A negative pressure is created inside the protective cover through a negative pressure pipe, drawing the grinding waste into the telescopic pipe. The telescopic pipe ensures stable raising and lowering of the protective cover. The extracted waste is then transported to a waste collection box through the telescopic pipe. When the drive gear rotates, it drives the driven gear to mesh and rotate. The driven gear then drives the upper scraper to rotate, causing the upper scraper to scrape away the waste residue remaining on the top of the inner side of the protective cover. The rotation of the upper scraper drives the side scraper to rotate synchronously, causing the side scraper to scrape away the waste residue remaining on the inner wall of the protective cover. This allows the waste residue inside the protective cover to be fully sucked into the waste residue box by the negative pressure pipe. The waste residue box is used to collect the waste residue generated by grinding, thereby effectively preventing waste residue from splashing everywhere, timely sucking away residual waste residue that is statically attached to the device, reducing the difficulty of subsequent cleaning operations, and enhancing the practical value of the device.

[0008] Preferably, two sets of grinding rollers and two sets of telescopic rods are symmetrically arranged. The protective cover is located above the fixed frame. One end of the negative pressure pipe is connected to the inside of the protective cover. The drive gear is rotatably connected to the protective cover. The driven gear is located on the outside of the negative pressure pipe and is rotatably connected to the protective cover. The drive gear and the driven gear mesh and rotate. Two sets of upper scrapers are symmetrically arranged. The upper scraper is set close to the top of the inner side of the protective cover. The side scraper is set vertically at one end of the upper scraper and is set close to the inner wall of the protective cover.

[0009] Preferably, one end of the telescopic rod is provided with a connecting plate, which is located on the outside of the protective cover. The bottom surface of the protective cover is provided with a sealing ring, and the upper surface of the work platform is provided with a sealing groove, with the sealing ring and the sealing groove fitting together.

[0010] Preferably, an air pump is installed on the outside of the negative pressure pipe, and the air pump is electrically connected to the control console. A chip discharge pipe is installed on the bottom of the waste bin, and the chip discharge pipe runs through the workbench. A solenoid valve is installed on the outside of the chip discharge pipe, and the solenoid valve is electrically connected to the control console.

[0011] Preferably, a second motor is provided on the upper surface of the protective cover. The second motor is electrically connected to the control console. The output end of the second motor is connected to the drive gear. A cavity is provided on the inner side of the top of the protective cover. The drive gear and the driven gear are located inside the cavity. An annular groove is provided on the top inner side of the protective cover. The annular groove is located on the outer side of one end of the negative pressure pipe. A connecting ring is provided on the bottom surface of the driven gear. One end of the upper scraper is located on the outer side of the connecting ring. A second sliding groove is provided on the top inner side of the protective cover. One end of the upper scraper is fitted and slidably connected along the second sliding groove.

[0012] Preferably, the top of the fixing frame is provided with a rotating plate, the bottom surface of the rotating plate is provided with an adjusting screw, the adjusting screw passes through the fixing frame and is threadedly connected to the fixing frame, one end of the adjusting screw is provided with a pressure plate, the adjusting screw and the pressure plate are rotatably connected to each other, the pressure plate is set above the sheet body, and sliders are provided on both sides of the pressure plate. The inner side of the fixing frame is provided with a first sliding groove, and two sets of the first sliding groove are symmetrically provided. The sliders are engaged and slidably connected with the first sliding groove.

[0013] Preferably, the grinding roller is provided with support frames at both ends, the support frames are rotatably connected to the grinding roller, a first motor is provided on one side of the support frame, the first motor is electrically connected to the control console, and the output end of the first motor is connected to the drive shaft of the grinding roller.

[0014] The beneficial effects of this utility model are:

[0015] During the grinding operation, the sheet material to be ground is placed on the fixed frame supported by the worktable. A telescopic command is sent to the telescopic rod via the control console. The telescopic rod extends and retracts, causing the protective cover to rise and fall. The protective cover seals the fixed frame inside, preventing waste from flying everywhere. The grinding rollers rotate to grind both sides of the sheet material. A negative pressure is created inside the protective cover through a negative pressure pipe, drawing the grinding waste into the telescopic pipe. The telescopic pipe ensures stable raising and lowering of the protective cover. The extracted waste is then transported to a waste collection box through the telescopic pipe. Simultaneously, the drive gear rotates, engaging the driven gear. The rotating driven gear drives the upper scraper to rotate, causing it to scrape away the waste residue remaining on the top of the inner side of the protective cover. The rotation of the upper scraper drives the side scraper to rotate synchronously, causing it to scrape away the waste residue remaining on the inner wall of the protective cover. This allows the waste residue inside the protective cover to be fully sucked into the waste residue box by the negative pressure pipe. The waste residue box is used to collect the waste residue generated during grinding, which solves the problem that most plastic sheet grinding devices produce waste residue that flies everywhere during grinding. The waste residue is small in size and may be scattered in various corners of the workbench, polluting the working environment. In addition, the waste residue often forms static electricity, making it difficult to clean. This enhances the practical value of the device. Attached Figure Description

The cavity 1102 fixes the installation positions of the drive gear 11 and the driven gear 12. Rotating the driven gear 12 drives the connecting ring 1201 to rotate. The ring groove 1103 allows the connecting ring 1201 to pass through the bottom of the protective cover 7. The upper scraper 13 is connected and fixed through the connecting ring 1201, thereby driving the upper scraper 13 to rotate and scrape off the waste.

[0027] Please see Figure 5In this embodiment, a rotating plate 301 is provided on the top of the fixing frame 3, and an adjusting screw 302 is provided on the bottom surface of the rotating plate 301. The adjusting screw 302 passes through the fixing frame 3 and is threadedly connected to the fixing frame 3. A pressure plate 303 is provided at one end of the adjusting screw 302, and the adjusting screw 302 and the pressure plate 303 are rotatably connected. The pressure plate 303 is located above the sheet body 4, and sliders 304 are provided on both sides of the pressure plate 303. A first sliding groove 305 is provided on the inner side of the fixing frame 3. Two sets of first sliding grooves 305 are symmetrically provided. The sliders 304 are engaged and slidably connected with the first sliding grooves 305. Rotating the rotating plate 301 drives the adjusting screw 302 to rotate. Rod 302 drives pressure plate 303 to rise and fall, causing slider 304 to slide up and down along first slide groove 305, thereby ensuring stable rise and fall of pressure plate 303. Pressure plate 303 is used to press and fix sheet body 4. Support frame 501 is provided at both ends of grinding roller 5. Support frame 501 is rotatably connected to grinding roller 5. First motor 502 is provided on one side of support frame 501. First motor 502 is electrically connected to control console 2. Output end of first motor 502 is connected to drive shaft of grinding roller 5. Grinding roller 5 is rotatably connected through support frame 501. Control console 2 sends running command to first motor 502. First motor 502 drives grinding roller 5 to rotate. Rotating grinding roller 5 grinds sheet body 4.

[0028] Before the grinding operation, the sheet body 4 to be ground is placed on the fixed frame 3. The fixed frame 3 and the grinding roller 5 limit the sheet body 4 around. The rotating plate 301 drives the adjusting screw 302 to rotate downward. The downward rotation of the adjusting screw 302 drives the pressure plate 303 to move downward. At the same time, the slider 304 moves downward along the first sliding groove 305, so that the pressure plate 303 presses the sheet body 4 tightly.

[0029] Subsequently, a retraction command is sent to the telescopic rod 6 via the control console 2. The retraction of the telescopic rod 6 causes the connecting plate 601 to move down, thereby causing the protective cover 7 to descend. At the same time, the telescopic tube 9 is stretched, embedding the sealing ring 701 into the sealing groove 702, so that the protective cover 7 seals and protects the fixing frame 3 inside.

[0030] During the grinding operation, the air pump 801 is started through the control console 2. The air pump 801 controls the negative pressure pipe 8 to generate negative pressure inside the protective cover 7. The control console 2 sends a running command to the first motor 502. The first motor 502 drives the grinding roller 5 on the support frame 501 to rotate. The rotating grinding roller 5 grinds both sides of the sheet body 4. The waste generated during grinding is sucked into the telescopic pipe 9 through the negative pressure pipe 8. The extracted waste is then transported into the waste bin 10 through the telescopic pipe 9.

[0031] Simultaneously, the control console 2 sends an operating command to the second motor 1101, which drives the drive gear 11 in the cavity 1102 to rotate. The rotation of the drive gear 11 drives the driven gear 12 to mesh and rotate. The rotation of the driven gear 12 drives the connecting ring 1201 to rotate in the ring groove 1103. The rotation of the connecting ring 1201 drives the upper scraper 13 to rotate along the second slide groove 1301. The rotation of the upper scraper 13 scrapes away the waste residue remaining on the top of the inner side of the protective cover 7. At the same time, it drives the side scraper 14 to rotate synchronously. The rotation of the side scraper 14 scrapes away the waste residue remaining on the inner wall of the protective cover 7.

[0032] Finally, the grinding roller 5 is stopped by the control console 2, and an extension command is sent to the telescopic rod 6. The telescopic rod 6 is extended to raise the protective cover 7 and the polished sheet body 4 is taken out from the worktable 1. An opening command is sent to the solenoid valve 1002 by the control console 2 to open the solenoid valve 1002 and thus open the chip discharge pipe 1001. The chip discharge pipe 1001 is used to discharge the waste chips in the waste chip box 10.

[0033] Through the above steps, the workbench 1 is supported by a fixed frame 3, which is used to place the sheet material 4 to be ground. The grinding roller 5 rotates to grind both sides of the sheet material 4. The control console 2 sends a telescopic command to the telescopic rod 6, which in turn moves the protective cover 7 up and down. The protective cover 7 seals the fixed frame 3 inside, preventing waste from flying everywhere. A negative pressure is generated inside the protective cover 7 through the negative pressure pipe 8, which draws the grinding waste into the telescopic pipe 9. The telescopic pipe 9 ensures the stable raising and lowering of the protective cover 7. The extracted waste is then transported to the waste disposal area through the telescopic pipe 9. Inside the waste bin 10, the drive gear 11 rotates, causing the driven gear 12 to mesh and rotate. The driven gear 12 rotates, causing the upper scraper 13 to rotate, so that the upper scraper 13 scrapes away the waste residue remaining on the top of the inner side of the protective cover 7. The rotation of the upper scraper 13 drives the side scraper 14 to rotate synchronously, and the rotation of the side scraper 14 scrapes away the waste residue remaining on the inner wall of the protective cover 7. This allows the waste residue inside the protective cover 7 to be fully sucked into the waste bin 10 by the negative pressure pipe 8. The waste bin 10 is used to collect the waste residue generated by grinding in a unified manner, thereby effectively preventing waste residue from flying everywhere and timely sucking away residual waste residue that is statically attached to the device, reducing the difficulty of subsequent cleaning operations.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
