Description

Technical Field

[0001] This invention relates to the field of stone plastic flooring processing technology, and in particular to a board grinding mechanism for manufacturing stone plastic flooring. Background Technology

[0002] Stone plastic flooring, also known as stone plastic floor tiles, is formally called "PVC sheet flooring." It is a high-quality, high-tech new type of floor decoration material. It uses natural marble powder to form a solid base layer with a high-density, high-fiber mesh structure, and the surface is covered with a highly wear-resistant polymer PVC layer. It is processed through hundreds of steps. During the processing of stone plastic flooring, the boards often need to be polished.

[0003] Currently, existing boards generate a large amount of dust during the sanding process. This dust permeates the working environment, endangering the health of operators and potentially causing safety accidents such as dust explosions. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a board grinding mechanism for manufacturing stone plastic flooring, which overcomes the shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a grinding mechanism for stone-plastic flooring manufacturing, comprising a base plate, two vertical plates symmetrically connected to the upper end of the base plate, a reciprocating screw rotatably connected between the two vertical plates, a rotating assembly for driving the reciprocating screw rotatably mounted on the vertical plates, a movable block threadedly connected to the wall of the reciprocating screw, a mounting plate connected to the lower end of the movable block, a cylinder mounted on the lower end of the mounting plate, a grinder connected to the piston end of the cylinder, and a grinding tool mounted on the upper end of the mounting plate. The system includes a vacuum cleaner with a suction pipe rotatably connected to its lower end. The lower end of the suction pipe passes through the side wall of the mounting plate and extends downwards, where a suction head is installed. A water tank is located above the base plate and is mounted on the upper part of the corresponding vertical plate. A water delivery hose is connected to one side wall of the water tank, and a nozzle is installed at the other end of the water delivery hose. The nozzle is mounted on the mounting plate. A water spraying assembly for spraying water from the water tank is installed on the vertical plate. Two support frames are symmetrically connected to the upper part of the base plate, and clamping assemblies are installed on the support frames.

[0006] By adopting the above technical solution, during use, the board to be ground is placed on two support frames. The cylinder is activated, causing the grinder to move downwards. When the grinder contacts the board, it is activated again, and the reciprocating screw is rotated via a rotating assembly. The rotation of the reciprocating screw applies force to the moving block through the thread action. The force on the moving block causes the mounting plate to move, which in turn moves the cylinder and the grinder. The grinder then grinds the board. Simultaneously, a vacuum cleaner is activated, using a suction pipe and suction head to absorb the dust generated during grinding. Meanwhile, a water tank discharges cleaning water through a water hose to a spray nozzle, which sprays water onto the board surface to cool the grinder and the board, and also to reduce dust. This structure effectively absorbs dust generated during grinding and sprays water onto the board surface, achieving both dust reduction and cooling, thus improving the applicability of the device.

[0007] As a preferred embodiment of the present invention, the rotating assembly includes a motor fixedly mounted on the side wall of the corresponding vertical plate, and the output end of the motor is connected to a reciprocating lead screw via a coupling.

[0008] By adopting the above technical solution, starting the motor will cause the reciprocating lead screw to rotate.

[0009] As a preferred embodiment of the present invention, the water spraying assembly includes a baffle that is slidably connected to the inner side wall of one side of the water storage tank, and the baffle is located at the position of the water delivery hose. One end of the reciprocating screw is connected to a rotating disk, a transmission rod is hinged to the side wall of one side of the rotating disk, and a movable rod is hinged to the other end of the transmission rod. The upper end of the movable rod passes through the bottom end of the water storage tank and is connected to the baffle.

[0010] By adopting the above technical solution, the rotation of the reciprocating screw drives the rotating disk to rotate, which in turn drives the transmission rod to rotate. The rotation of the transmission rod drives the movable rod to make a vertical reciprocating motion, which in turn drives the baffle to make a vertical reciprocating motion. When the baffle moves away from the water supply hose, the cleaning water is discharged into the nozzle through the water supply hose. When the baffle moves back to the position of the water supply hose, it blocks the opening of the water supply hose, preventing the cleaning water from being discharged from the water supply hose. This avoids the continuous discharge of cleaning water, prevents the waste of water resources, and improves the practicality of the device.

[0011] As a preferred embodiment of the present invention, a sliding groove is provided on the side wall of one side of the vertical plate, and a slider is slidably connected in the sliding groove. One end of the slider passes through the opening of the sliding groove and extends outward and is connected to the movable rod.

[0012] By adopting the above technical solution, the movable rod is limited, thereby improving the stability of its movement.

[0013] As a preferred embodiment of the present invention, a sliding rod is fixedly connected to the inner wall of the chute, the sliding rod passes through the slider, and the slider is slidably connected to the sliding rod.

[0014] By adopting the above technical solution, the slider is prevented from detaching from the groove.

[0015] As a preferred embodiment of the present invention, one end of the slider is provided with a rolling groove, and a rolling ball is provided in the rolling groove. The rolling ball passes through the opening of the rolling groove and is tumblingly connected to the bottom of the groove.

[0016] By adopting the above technical solution, the friction between the slider and the groove is reduced.

[0017] As a preferred embodiment of the present invention, a rack is connected between the two vertical plates, and a gear is fixedly sleeved on the wall of the suction pipe, with the rack meshing with the gear.

[0018] By adopting the above technical solution, the movement of the mounting plate will drive the suction pipe to move, the movement of the suction pipe will drive the gear to move, the movement of the gear will be driven by the rack to rotate the suction pipe, and the rotation of the suction pipe will drive the suction head to rotate, increasing the contact area between the suction head and the air, increasing the suction range, and improving the suction effect.

[0019] As a preferred embodiment of the present invention, a guide rod is connected between the two vertical plates, the guide rod passes through the movable block, and the movable block is slidably connected to the guide rod.

[0020] By adopting the above technical solution, the movable block is limited to prevent it from rotating.

[0021] As a preferred embodiment of the present invention, a float plate is provided inside the water storage tank, and a warning ruler is connected to the upper end of the float plate. The upper end of the warning ruler passes through the top of the water storage tank and extends upward.

[0022] By adopting the above technical solution, when the cleaning water is discharged, the liquid level in the water tank will drop, the float will move downward, and the movement of the float will drive the warning ruler downward. By observing the position of the warning ruler, the condition of the cleaning water inside the water tank can be judged.

[0023] As a preferred embodiment of the present invention, the clamping assembly includes two electric push rods fixedly mounted on the upper end of the support frame, and the piston end of the electric push rod is connected to a clamping plate.

[0024] By adopting the above technical solution, when the board is placed on the support frame, the electric push rod is activated. The operation of the electric push rod will drive the clamping plates to move, and the two clamping plates will clamp and fix the board.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] (1) This invention comprises a base plate, a vertical plate, a reciprocating lead screw, a movable block, a mounting plate, a cylinder, a grinder, a motor, a vacuum cleaner, a vacuum hose, a vacuum head, a water tank, a water hose, and a nozzle. In use, the material to be ground is placed on two support frames. The cylinder is activated, causing the grinder to move downwards. When the grinder contacts the material, the motor rotates the reciprocating lead screw. This rotation applies force to the movable block via the threaded action. The movable block, under this force, moves the mounting plate, which in turn moves the material. The cylinder and the grinder move, and the grinder grinds the board. At the same time, the vacuum cleaner is activated, and it absorbs the dust generated during grinding through the suction pipe and suction head. Meanwhile, the water tank discharges cleaning water to the spray head through the water hose, and the spray head sprays water onto the surface of the board to cool the grinder and the board. This also helps to reduce dust. Through the above structure, the dust generated during the grinding of the board can be absorbed, and water can be sprayed on the surface of the board to reduce dust and cool it down, thereby improving the applicability of the device.

[0027] (2) This invention, by setting up a baffle, a rotating disk, a transmission rod, a movable rod, a slider, a sliding rod, and a ball bearing, etc., the rotation of the reciprocating screw will drive the rotating disk to rotate, the rotation of the rotating disk will drive the transmission rod to rotate, the rotation of the transmission rod will drive the movable rod to make a vertical reciprocating motion, and the motion of the movable rod will drive the baffle to make a vertical reciprocating motion. When the baffle moves away from the position of the water supply hose, the cleaning water will be discharged into the nozzle through the water supply hose. When the baffle moves back to the position of the water supply hose, it will block the opening of the water supply hose to prevent the cleaning water from being discharged from the water supply hose. Thus, the cleaning water can be prevented from being discharged continuously, preventing the waste of water resources, thereby improving the practicality of the device. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1-4 A grinding mechanism for stone-plastic flooring manufacturing includes a base plate 1. Two vertical plates 2 are symmetrically fixedly connected to the upper end of the base plate 1. A reciprocating screw 3 is rotatably connected between the two vertical plates 2. A rotating assembly for driving the reciprocating screw 3 is installed on the vertical plates 2. The rotating assembly includes a motor 8 fixedly installed on the side wall of the corresponding vertical plate 2. The output end of the motor 8 is connected to the reciprocating screw 3 via a coupling. Starting the motor 8 drives the reciprocating screw 3 to rotate. A movable block 4 is threadedly connected to the wall of the reciprocating screw 3. A guide rod 24 is connected between the two vertical plates 2. The guide rod 24 passes through the movable block 4, and the movable block 4 is slidably connected to the guide rod 24. A limit switch is installed to prevent the movable block 4 from rotating. The lower end of the movable block 4 is connected to a mounting plate 5, and the lower end of the mounting plate 5 is equipped with a cylinder 6. The piston end of the cylinder 6 is connected to a grinder 7. In use, the material to be ground is placed on the two support frames, and the cylinder 6 is started. The cylinder 6 will drive the grinder 7 to move downward. When the grinder 7 contacts the material, the grinder 7 is started. At the same time, the reciprocating screw 3 is rotated by the motor 8. The rotation of the reciprocating screw 3 will apply a force to the movable block 4 through the thread action. The movable block 4 is subjected to a force that drives the mounting plate 5 to move. The movement of the mounting plate 5 will drive the cylinder 6 and the grinder 7 to move. The movement of the grinder 7 will grind the material.

[0037] A vacuum cleaner 9 is mounted on the upper end of the mounting plate 5. A suction pipe 10 is rotatably connected to the lower end of the vacuum cleaner 9. The lower end of the suction pipe 10 passes through the side wall of the mounting plate 5 and extends downward, where a suction head 11 is installed. A rack 22 is connected between the two vertical plates 2. A gear 23 is fixedly sleeved on the wall of the suction pipe 10. The meshing of the rack 22 and the gear 23 causes the movement of the mounting plate 5 to drive the suction pipe 10 to move. The movement of the suction pipe 10 drives the gear 23 to move. The movement of the gear 23 is driven by the force of the rack 22 to rotate the suction pipe 10. The rotation of the suction pipe 10 drives the suction head 11 to rotate, increasing the contact area between the suction head 11 and the air, increasing the suction range, and improving the suction effect. At the same time, when the vacuum cleaner 9 is started, it will absorb the dust generated during polishing through the suction pipe 10 and the suction head 11.

[0038] A water storage tank 12 is installed above the base plate 1. The water storage tank 12 is installed on the upper end of the corresponding vertical plate 2. A water supply hose 13 is connected to one side wall of the water storage tank 12. A nozzle 14 is installed at the other end of the water supply hose 13. The nozzle 14 is installed on the mounting plate 5. The water storage tank 12 discharges cleaning water into the nozzle 14 through the water supply hose 13. The nozzle 14 then sprays the water onto the surface of the board to cool the sander 7 and the board. At the same time, it can also reduce dust. A float 25 is installed inside the water storage tank 12. A warning ruler 26 is connected to the upper end of the float 25. The upper end of the warning ruler 26 passes through the top of the water storage tank 12 and extends upward. When the cleaning water is discharged, the liquid level in the water storage tank 12 will drop, and the float 25 will move downward. The movement of the float 25 will drive the warning ruler 26 to move downward. By observing the position of the warning ruler 26, the condition of the cleaning water inside the water storage tank 12 can be judged.

[0039] A water spraying assembly for spraying water from the water storage tank 12 is installed on the vertical plate 2. The water spraying assembly includes a baffle 15 slidably connected to the inner side wall of one side of the water storage tank 12, and the baffle 15 is located at the position of the water delivery hose 13. One end of the reciprocating screw 3 is connected to a rotating disk 16, and a transmission rod 17 is hinged to the side wall of one side of the rotating disk 16. The other end of the transmission rod 17 is hinged to a movable rod 18. The upper end of the movable rod 18 passes through the bottom end of the water storage tank 12 and is connected to the baffle 15. The rotation of the reciprocating screw 3 will drive the rotating disk 16 to rotate, and the rotation of the rotating disk 16 will drive the transmission rod 17. When the transmission rod 17 rotates, it drives the movable rod 18 to move back and forth vertically. The movement of the movable rod 18 drives the baffle 15 to move back and forth vertically. When the baffle 15 moves away from the water supply hose 13, the cleaning water will flow into the nozzle 14 through the water supply hose 13. When the baffle 15 moves back to the position of the water supply hose 13, it will block the opening of the water supply hose 13, preventing the cleaning water from flowing out of the water supply hose 13. This avoids the continuous discharge of cleaning water, prevents the waste of water resources, and improves the practicality of the device.

[0040] A groove is provided on one side wall of the vertical plate 2. A slider 19 is slidably connected in the groove. One end of the slider 19 passes through the groove opening and extends outward and is connected to the movable rod 18 to limit the movement of the movable rod 18 and improve the stability of the movement of the movable rod 18. A slide rod 20 is fixedly connected to the groove wall. The slide rod 20 passes through the slider 19 and the slider 19 is slidably connected to the slide rod 20 to prevent the slider 19 from detaching from the groove. A rolling groove is provided at one end of the slider 19. A rolling ball 21 is provided in the rolling groove. The ball 21 passes through the groove opening and is slidably connected to the bottom of the groove to reduce the friction between the slider 19 and the groove.

[0042] Working principle: In use, the material to be ground is placed on the two support frames. The electric push rod 27 is activated, which moves the clamping plates 28, clamping and fixing the material. The cylinder 6 is activated, causing the grinder 7 to move downwards. When the grinder 7 contacts the material, it is activated, and the motor 8 rotates the reciprocating screw 3. The rotation of the reciprocating screw 3 applies force to the movable block 4 through the thread action. The movable block 4 is subjected to… The force will drive the mounting plate 5 to move, and the movement of the mounting plate 5 will drive the cylinder 6 and the grinder 7 to move. The movement of the grinder 7 will grind the board. At the same time, the vacuum cleaner 9 will be started, and the vacuum cleaner 9 will absorb the dust generated during grinding through the suction pipe 10 and the suction head 11. Meanwhile, the water tank 12 will discharge cleaning water into the spray head 14 through the water supply hose 13.
