Description

Technical Field

[0001] The invention belongs to the technical field of cyclic grinding and polishing, in particular to a device for cyclic grinding and polishing of columnar stones. Background Art

[0002] Stone is a rock used as a material. From the perspective of water permeability, stone belongs to sand and gravel water-permeable material. Roads and bridge buildings in stone production lines are subject to the complex force system of vehicle loads and the adverse effects of various complex natural factors. Therefore, people are very strict when selecting stones. Different stones have different uses. Now most stones are used for decoration. Therefore, stones need to be ground and polished before they can be used.

[0003] A patent with announcement number CN114178914B discloses a columnar marble grinding and polishing device and its use method. The device can firmly clamp the stone column through a clamping device to ensure that the stone column will not loosen during the grinding process, thereby ensuring the grinding effect of the stone column. By controlling the movement of the grinding block by two hydraulic devices, the surface of the stone column can be more finely ground and polished, thereby making the roughness of the surface of the stone column lower, thereby achieving better grinding effect and avoiding the occurrence of uneven manual grinding. Blowing away debris with air can prevent debris from remaining on the surface of the stone column, thereby avoiding the impact of debris on the grinding of the stone column, thereby improving the grinding effect and making the surface of the stone column smoother. In addition, by applying glue to the stone column, grooves on the surface of the stone column that cannot be polished can be repaired, and the glue can be quickly dried by heating the air, which is beneficial to grinding and improves the efficiency of grinding.

When grinding and polishing columnar stones, the grinding mechanism is usually controlled to move slowly on the surface of the columnar stone to grind and polish the surface of the columnar stone. At the same time, the grinding surface of the columnar stone needs to be adjusted from time to time. However, this grinding and polishing operation method is not only cumbersome, but also difficult to control the grinding and polishing force, which easily leads to uneven grinding and polishing of the surface of the columnar stone.

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0039] Example 1: Figures 1 to 9 As shown, a cylindrical stone circulating grinding and polishing device according to an embodiment of the present invention includes a frame 1, a material guide frame 2 is installed on one side of the upper end surface of the frame 1, a bracket 4 is installed in the middle of the upper end surface of the frame 1, and a loading and unloading assembly 6 is provided at one end of the bracket 4;

[0040] The loading and unloading assembly 6 includes a U-shaped chute 61 provided in the upper end of the bracket 4. A slider 62 is slidably connected to the inner cavity of the U-shaped chute 61, and push blocks 63 are rotatably connected to both ends of the slider 62. A tension spring is fixed to one side of the slider 62, and one end of the tension spring is fixed to the inner wall of the U-shaped chute 61.

[0041] One end of the bracket 4 is rotatably connected to a blanking plate 610, and a guide groove is provided on the upper end surface of the blanking plate 610 for guiding the polished columnar stone 12 for blanking;

[0042] A winding groove 611 is provided in one end of the bracket 4. A winding frame 65 is rotatably connected to the inner cavity of the winding groove 611. A traction rope 64 is wound on the outside of the traction frame 65, and one end of the traction rope 64 is fixedly connected to the slider 62.

[0043] The upper end of the frame 1 is located on both sides of the bracket 4, and a rubber wheel 5 and a grinding wheel 19 are respectively provided. The grinding wheel 19 and the rubber wheel 5 rotate clockwise at the same time, and the rotation speed of the grinding wheel 19 is higher than that of the rubber wheel 5. The grinding wheel 19 and the rubber wheel 5 can use the friction force to apply a net thrust to the columnar stone 12, so that the columnar stone 12 is moved and transported to the unloading plate 610.

[0044] Specifically, in the prior art, a columnar stone is usually placed on a workbench for clamping and fixing, and then a grinding mechanism is controlled to approach the surface of the columnar stone for grinding. However, although this operation method can grind the columnar stone, it is difficult to control the grinding force, which easily causes the columnar stone to be over-grinded. Moreover, during the grinding process, it is difficult to grind the entire surface of the columnar stone, which easily causes a layered feeling on the surface of the columnar stone after grinding, affecting the quality of the columnar stone after grinding, and greatly reducing the grinding and polishing efficiency of the columnar stone.

[0045] The present invention, when grinding and polishing the columnar stone 12, guides the columnar stone 12 to fall accurately on the bracket 4 by using the guide frame 2, and pushes the columnar stone 12 to move between the grinding wheel 19 and the rubber wheel 5, and drives the grinding wheel 19 and the rubber wheel 5 to rotate, and the rotation speed of the grinding wheel 19 is higher than that of the rubber wheel 5, so that the outer surface of the columnar stone 12 can be grinded and polished by using the grinding wheel 19, and the rubber wheel 5, which is lower than the rotation speed of the grinding wheel 19, will transmit the columnar stone 12 to form a friction force, and at the same time cooperate with the grinding wheel 19 to apply a net thrust to the columnar stone 12 during the grinding process, so that the entire surface of the columnar stone 12 is ground and polished during the movement. After the grinding and polishing process is completed, the columnar stone 12 is transported to the blanking plate 610, and the blanking plate 610 is turned downward by using the weight of the columnar stone 12 itself, so that the columnar stone 12 moves downward. The material plate 610 slides downward to discharge the material. At the same time, the material plate 610 will drive the winding rack 65 to rotate during the flipping process. At the same time, the winding rack 65 will drive the traction rope 64 to reel in. During the reeling process, the traction rope 64 will pull the slider 62 to slide in the inner cavity of the U-shaped slide 61. At the same time, the slider 62 drives the pushing block 63 to move synchronously, so that the pushing block 63 pushes the columnar stone 12 to be polished from the inner cavity of the guide frame 2, and uses the pushing block 63 to push the columnar stone 12 into between the grinding wheel 19 and the rubber wheel 5. After the polished columnar stone 12 is discharged and recovered from the material plate 610, the material plate 610 will flip and reset, and at the same time, the tension spring will pull the slider 62 to move and reset, thereby realizing the automatic loading and unloading and grinding of the columnar stone 12, improving the grinding and polishing efficiency of the columnar stone, and making the grinding and polishing device highly automated, thereby solving the above-mentioned problem.

[0046] like Figures 5 to 7 As shown, the inner cavity of the winding groove 611 is rotatably connected to a rotating shaft 67, and both ends of the rotating shaft 67 pass through the bracket 4 and are fixedly connected to the blanking plate 610. Two transmission gears 68 are fixedly connected to the outside of the rotating shaft 67, and a torsion spring 69 is fixedly connected to one side of the transmission gear 68, and one end of the torsion spring 69 is fixedly connected to the inner wall of the winding groove 611.

[0047] Specifically, after the columnar stone 12 is ground and polished, the grinding wheel 19 and the rubber wheel 5 will transport the ground columnar stone 12 to the blanking plate 610, and at the same time use the weight of the columnar stone 12 itself to drive the blanking plate 610 to flip over, and make the blanking plate 610 drive the rotating shaft 67 to rotate, and the rotating shaft 67 will drive the transmission gear 68 to rotate, and at the same time the transmission gear 68 drives the torsion spring 69 to twist, thereby causing the blanking plate 610 to flip downward and tilt at a certain angle, and the columnar stone 12 will be discharged and recycled, and a conveyor belt can be set under the blanking plate 610, so that the columnar stone 12 can be discharged onto the conveyor belt for transportation and recycling, thereby realizing the automatic discharge and recovery of the columnar stone 12 and improving the degree of automation of the grinding and polishing device.

[0048] like Figures 5 to 7 As shown, the transmission gear 68 is meshed and connected with the driven gear 66, and the driven gear 66 is fixedly installed on the winding rack 65. The teeth of the transmission gear 68 are five times the teeth of the driven gear 66, so that the transmission gear 68 can rotate half a circle to mesh with the driven gear 66 to rotate two and a half circles, and at the same time, the driven gear 66 drives the winding rack 65 to pull and wind the traction rope 64.

[0049] like Figures 5 to 7 and Figure 9 As shown, grooves 20 are opened at both ends of the slider 62, and the pushing block 63 is located outside the inner cavity of the groove 20 and is fixedly connected to a fixed plate 21. A return torsion spring 22 is fixedly connected to one side of the fixed plate 21, and one end of the return torsion spring 22 is fixedly connected to the inner wall of the groove 20.

[0050] Specifically, when the weight of the columnar stone 12 is used to drive the blanking plate 610 to flip and discharge the material, the blanking plate 610 will drive the rotating shaft 67 to rotate, and at the same time the rotating shaft 67 will drive the transmission gear 68 to rotate, and the transmission gear 68 drives the torsion spring 69 to twist, thereby causing the blanking plate 610 to flip downward and tilt at a certain angle, so that the columnar stone 12 can be discharged and recovered. In the process of the blanking plate 610 flipping downward, the rotating shaft 67 will drive the transmission gear 68 to rotate, and the transmission gear 68 will mesh with the transmission driven gear 66 to rotate. Since the teeth of the transmission gear 68 are five times that of the driven gear 66, the transmission gear 68 can rotate half a circle to mesh with the transmission driven gear The gear 66 rotates two and a half circles, and at the same time, the driven gear 66 drives the winding rack 65 to pull and reel the traction rope 64, and the traction rope 64 will pull the slider 62 to slide in the inner cavity of the U-shaped slide 61, and at the same time, the slider 62 drives the pushing block 63 to push out the columnar stone 12 in the inner cavity of the guide rack 2, and push the columnar stone 12 between the grinding wheel 19 and the rubber wheel 5, thereby solving the problem that the existing columnar stone circulation grinding and polishing device is difficult to automatically push the columnar stone for grinding and polishing during the grinding and polishing process of the columnar stone, and discharge the polished columnar stone, resulting in difficulty in forming an automated form of grinding and polishing of the columnar stone and low grinding and polishing efficiency.

[0051] like Figures 1 to 3 As shown, a storage box 3 is fixedly connected to the upper end of the guide frame 2, and the storage box 3 is used to store columnar stones 12.

[0052] like Figure 4 、 Figure 7 and Figure 8 As shown, a number of balls are evenly arranged in the upper end of the bracket 4, and the balls located in the middle of the bracket 4 are smaller than the balls on both sides of the upper end of the bracket 4, which are used to reduce the friction of the columnar stone 12.

[0053] Specifically, when the columnar stone 12 is ground and transported by using the grinding wheel 19 in conjunction with the speed difference of the rubber wheel 5, since a number of balls are evenly arranged on the upper end of the bracket 4, and the balls located in the middle of the bracket 4 are smaller than the balls on both sides of the upper end of the bracket 4, columnar stones 12 of different sizes can be lifted, and the balls in the middle are smaller than the balls on both sides of the upper end of the bracket 4, thereby ensuring that the columnar stone 12 always remains in the center of the bracket 4. At the same time, the setting of the balls can reduce the friction between the columnar stone 12 and the bracket 4, ensuring that the grinding wheel 19 cooperates with the speed difference of the rubber wheel 5 to stably transport and grind the columnar stone 12, thereby further improving the stability of the grinding and transportation of the columnar stone 12, and improving the grinding and polishing efficiency of the columnar stone 12.

[0054] Example 2: Figure 1 and Figure 4As shown, an adjustment component 8 is provided on one side of the upper end surface of the frame 1, and the adjustment component 8 includes a limit groove opened on one side of the upper end surface of the frame 1, and a two-way threaded rod 82 is rotatably connected to the inner cavity of the limit groove. One end of the two-way threaded rod 82 passes through the frame 1 and is fixed with a crank 81. The external threads of the two-way threaded rod 82 are connected to two support frames 83, and the upper ends of the two support frames 83 are rotatably installed with the grinding wheel 19 and the rubber wheel 5.

[0055] Specifically, when grinding and polishing columnar stones 12 of different sizes, the crank 81 is driven to rotate, and the crank 81 drives the bidirectional threaded rod 82 to rotate, and at the same time the bidirectional threaded rod 82 threaded transmission support frame 83 moves close to each other, and then the support frame 83 drives the grinding roller 19 and the rubber wheel 5 to move synchronously, and makes the grinding roller 19 and the rubber wheel 5 fit with the surface of the columnar stone 12, so that the grinding and polishing work can be adjusted according to the columnar stones 12 of different sizes, thereby solving the problem of the low applicability of the existing columnar stone circulation grinding and polishing device when grinding and polishing the surface of the columnar stone because it is difficult to adjust and grind the columnar stones of different sizes.

[0056] like Figure 1 、 Figure 3 and Figure 4 As shown, a second pulley 13 is installed at one end of the grinding wheel 19, a first pulley 9 is installed at one end of the rubber wheel 5, a protective cover 7 is rotatably installed on the upper end of the support frame 83, a water inlet 14 is opened on one side of the protective cover 7, and a plurality of spray holes are opened on the inner wall of the protective cover 7.

[0057] Specifically, when the columnar stone 12 is ground by the grinding wheel 19, the water inlet 14 is connected to the external tap water pipe, and then during the grinding process of the columnar stone 12, water mist can be sprayed by using the spray hole on the inner wall of the protective cover 7, and the water mist will be sprayed to the outside of the grinding wheel 19, so that the grinding wheel 19 is wet, and thus dust can be avoided during the grinding and polishing of the columnar stone 12, thereby solving the problem that if the dust generated by the grinding of the columnar stone is not cleared during the grinding and polishing of the columnar stone by the existing columnar stone circulating grinding and polishing device, the workers are prone to health problems due to long-term absorption of dust, and a large amount of dust will also affect the surrounding working environment.

[0058] like Figure 2 、 Figure 3 and Figure 8As shown, a transmission groove 10 is provided on the upper end surface of the frame 1, a servo motor 17 is installed in the inner cavity of the frame 1, and a transmission pulley 16 is installed on the output shaft end of the servo motor 17. The transmission pulley 16 is externally connected to the first belt 11 and the second belt 15, and one end of the first belt 11 is transmission-connected to the first pulley 9, and one end of the second belt 15 is transmission-connected to the second pulley 13. The setting of the first pulley 9 is larger than three times that of the transmission pulley 16, so that the transmission pulley 16 can rotate three circles to drive the first pulley 9 to rotate one circle, wherein the transmission pulley 16 and the second pulley 13 rotate synchronously, so that the grinding wheel 19 and the rubber wheel 5 form a wheel speed difference.

[0059] like Figure 2 、 Figure 3 and Figure 8 As shown, four limiting wheels 18 are rotatably connected to the inner wall of the transmission groove 10, and two limiting wheels 18 form a group, which are used for transmission connection with the first belt 11 and the second belt 15.

[0060] Specifically, when grinding and polishing the columnar stone 12, the servo motor 17 is started to drive the transmission pulley 16 to rotate, and the transmission pulley 16 drives the first belt 11 and the second belt 15 to rotate, and at the same time the first belt 11 and the second belt 15 drive the first pulley 9 and the second pulley 13 to rotate, and the first pulley 9 is set to be three times larger than the transmission pulley 16, so that the transmission pulley 16 can rotate three circles to drive the first pulley 9 to rotate one circle, and the first pulley 9 drives the rubber wheel 5 to rotate synchronously, and the second pulley 13 and the transmission pulley 16 are set to the same size, so that the transmission pulley 16 can rotate one circle, the second pulley 13 also rotates one circle, and at the same time the second pulley 13 drives the grinding wheel 19 to rotate synchronously, so that the grinding wheel 19 and the rubber wheel 5 form a wheel speed difference, thereby 9 During the surface grinding process of the columnar stone 12, the rubber wheel 5 drives the columnar stone 12 to rotate to form a static thrust, so that the columnar stone 12 rotates and moves slowly, and then cooperates with the grinding wheel 19 to grind and polish the entire surface of the columnar stone 12, thereby solving the problem that the existing columnar stone circulation grinding and polishing device usually controls the grinding mechanism to move slowly on the surface of the columnar stone to grind and polish the surface of the columnar stone, and it is also necessary to adjust the grinding surface of the columnar stone from time to time. However, this grinding and polishing operation method is not only cumbersome, but also difficult to control the grinding and polishing force, which easily causes uneven grinding and polishing of the columnar stone surface, and it is difficult to realize the automatic form of circulation grinding and polishing of the columnar stone, resulting in low efficiency of columnar stone grinding and polishing.

[0061] Working principle: When grinding and polishing the columnar stone 12, the servo motor 17 is started to drive the transmission pulley 16 to rotate, and the transmission pulley 16 drives the first belt 11 and the second belt 15 to rotate. At the same time, the first belt 11 and the second belt 15 drive the first pulley 9 and the second pulley 13 to rotate, and the setting of the first pulley 9 is greater than three times the transmission pulley 16, so that the transmission pulley 16 can rotate three circles to drive the first pulley 9 to rotate one circle, and the first pulley 9 drives the rubber wheel 5 to rotate synchronously, and the second pulley 1 3 and the driving pulley 16 are of the same size, so that when the driving pulley 16 rotates one circle, the second pulley 13 also rotates one circle, and at the same time, the second pulley 13 drives the grinding wheel 19 to rotate synchronously, so that the grinding wheel 19 and the rubber wheel 5 form a wheel speed difference, so that when the grinding wheel 19 grinds the surface of the columnar stone 12, the rubber wheel 5 drives the columnar stone 12 to rotate to form a static thrust, so that the columnar stone 12 rotates and moves slowly, and then cooperates with the grinding wheel 19 to grind and polish the entire surface of the columnar stone 12;

[0062] When grinding and polishing the columnar stone 12, the guide rack 2 is used to guide the columnar stone 12 to fall accurately on the bracket 4, and at the same time, the columnar stone 12 is pushed to move between the grinding wheel 19 and the rubber wheel 5, and the grinding wheel 19 and the rubber wheel 5 are driven to rotate. The rotation speed of the grinding wheel 19 is higher than that of the rubber wheel 5, so that the outer surface of the columnar stone 12 can be grinded and polished by the grinding wheel 19, and the rubber wheel 5, which is lower than the rotation speed of the grinding wheel 19, will transmit the columnar stone 12 to form a friction force, and at the same time cooperate with the grinding wheel 19 to apply a net thrust to the columnar stone 12 during the grinding process, so that the entire surface of the columnar stone 12 is ground and polished during the movement. After the grinding and polishing process is completed, the columnar stone 12 is transported to the blanking plate 610, and the blanking plate 610 is turned downward by the weight of the columnar stone 12 itself, so that the columnar stone 12 The material is discharged by sliding downward along the blanking plate 610. At the same time, the blanking plate 610 will drive the winding rack 65 to rotate during the flipping process. At the same time, the winding rack 65 will drive the traction rope 64 to reel in. During the reeling process, the traction rope 64 will pull the slider 62 to slide in the inner cavity of the U-shaped slide 61. At the same time, the slider 62 drives the pushing block 63 to move synchronously, so that the pushing block 63 pushes the columnar stone 12 to be polished out of the inner cavity of the guide frame 2, and uses the pushing block 63 to push the columnar stone 12 into between the grinding wheel 19 and the rubber wheel 5. After the polished columnar stone 12 is discharged and recovered from the blanking plate 610, the blanking plate 610 will flip and reset, and at the same time, the tension spring will pull the slider 62 to move and reset, thereby realizing the automatic loading and unloading and grinding of the columnar stone 12, improving the grinding and polishing efficiency of the columnar stone, and making the grinding and polishing device highly automated.

[0063] When the weight of the columnar stone 12 is used to drive the blanking plate 610 to flip and discharge the material, the blanking plate 610 will drive the rotating shaft 67 to rotate, and the rotating shaft 67 will drive the transmission gear 68 to rotate, and the transmission gear 68 drives the torsion spring 69 to twist, thereby causing the blanking plate 610 to flip downward and tilt at a certain angle, so that the columnar stone 12 can be discharged and recovered along the way. In the process of the blanking plate 610 flipping downward, the rotating shaft 67 will drive the transmission gear 68 to rotate, and the transmission gear 68 engages the transmission from The driven gear 66 rotates. Since the teeth of the transmission gear 68 are five times that of the driven gear 66, the transmission gear 68 can rotate half a circle to engage the driven gear 66 and rotate two and a half circles. At the same time, the driven gear 66 drives the winding rack 65 to pull and reel the traction rope 64, and the traction rope 64 will pull the slider 62 to slide in the inner cavity of the U-shaped slide 61. At the same time, the slider 62 drives the pushing block 63 to push out the columnar stone 12 in the inner cavity of the guide rack 2, and push the columnar stone 12 between the grinding wheel 19 and the rubber wheel 5.
