DETAILED DESCRIPTION

[0041] In the prior art, polishing of stone is generally carried out on a workbench, and separate manpower or manpower combined with machinery is required to complete the taking and placing of the stone before and after polishing. Since the stone is heavy, it consumes a lot of manpower and is low in efficiency.

[0042] And the existing technology produces more dust in the process of polishing stone, although the dust can be sucked by the existing dust suction device, but the polishing stone is generally polished by high-power polishing equipment, and the dust pollution range is wide, and the conventional dust suction device is difficult to improve the dust suction effect under the condition of controlling the cost.

[0043] Therefore, the application provides an automatic stone polishing and dust removal equipment integrated with negative pressure adsorption and filtration.

[0044] Specifically, as shown in Figure 1 and Figure 5 , the application is provided with suction holes 4 on the upper surface of the machining support platform 1, the suction holes 4 are provided with a plurality of suction holes 4, the inside of the machining support platform 1 is provided with a hollow groove 8, and the suction holes 4 are communicated with the hollow groove 8; the setting of the suction holes 4 increases the friction force of the surface of the machining support platform 1, so that the stone is not easy to slide off; and the inside of the machining support platform 1 is provided with a negative pressure fan 9, and the air outlet of the negative pressure fan 9 is communicated with the bottom of the machining support platform 1; the air inlet of the negative pressure fan 9 is communicated with the hollow groove 8.

[0045] Further, the size of the stone is usually smaller than the size of the machining support platform 1, so when the stone is placed on the machining support platform 1, there is a part of the suction holes 4 on the machining support platform 1 which is not covered by the stone, and when the stone is polished and the negative pressure fan 9 is started, the negative pressure fan 9 can suck the dust into the inside of the machining support platform 1, realizing the dust reduction effect and solving the dust reduction problem from the cutting source.

[0046] At the same time, the application can also be used in cooperation with other dust suction equipment when cutting stone.

[0047] As shown in Figure 3 and Figure 5 , the negative pressure fan 9 can be arranged inside the machining support platform 1 or outside the machining support platform 1, and can be arranged according to actual needs, when the negative pressure fan 9 is arranged inside the machining support platform 1, the air inlet of the negative pressure fan 9 needs to be installed with a filter element, so that the dust can be collected in the inside of the machining support platform 1, and will not enter the negative pressure fan 9 to affect the use of the negative pressure fan 9.

[0048] In daily use, opening the ash removal port 25 on the machining support platform 1 can achieve the purpose of ash removal, so as to maintain the normal use of the machining support platform 1.

[0049] It should be noted that the ash removal port 25 can be arranged at the bottom of the machining support platform 1, or at the side of the machining support platform 1, and the actual size can be designed for use.

[0050] Further, when there is water stain or the like on the machining support platform 1, the upper surface of the machining support platform 1 can be quickly dried by starting the negative pressure fan 9, which is convenient and practical.

[0051] Reference is made to the specific process of grinding the stone material shown in Figure 1 、 Figure 2 、 Figure 4 and Figure 9 , which is as follows:

[0052] A plurality of machining support platforms 1 are stacked one on another; the stone material is placed on the uppermost machining support platform 1, and the stone material is ground by using the grinding equipment.

[0053] Reference is made to the specific process of grinding the stone material shown in Figure 12 , which is as follows: the cutting machine 20 is further provided, the machined stone material can be discharged from the stone outlet 21 of the cutting machine 20 to the machining support platform 1, the bottom plate 19 is arranged below the stone outlet 21, the machining support platform 1 is placed on the bottom plate 19, the bottom plate 19 is used in cooperation with the lifting mechanism, the lifting mechanism comprises the gantry upper beam 16, the gantry column 18 and the chain 17, the gantry column 18 is arranged on one side of the cutting machine 20, the gantry upper beam 16 is fixed on the upper end of the gantry column 18, the winch for winding the chain 17 is arranged on the gantry upper beam 16, and the chain 17 is fixed on the upper surface of the bottom plate 19 at the lower end, so that the chain 17 is wound by the winch when the winch is started, thereby achieving the lifting of the bottom plate 19.

[0054] Further, the chain 17 is connected to the four corners of the upper surface of the bottom plate 19, the four chains 17 are wound by the four winches respectively, and the winch is connected to the pressure sensor 7 through the controller, so that when it is found that the machining support platform 1 is not balanced during the bearing process, the corresponding winch can be started alone to adjust the balance of the machining support platform 1, thereby avoiding the problem that the stone material is inclined and falls due to the imbalance during the bearing process.

[0055] When the stone material is on the machining support platform 1, the surface of the stone material can be ground by using the handheld grinding mechanism 26 or the mechanical arm to control the grinding equipment.

[0056] Reference is made to the specific process of grinding the stone material shown in Figure 13As shown in the figure, in another embodiment, although the plurality of processing support platforms 1 are stacked up and down to continuously support the stone, when the upper and lower stacked processing support platforms 1 are used up, they need to be manually replaced according to the needs, and this process will still temporarily stop supporting the stone, affecting the production efficiency. Therefore, in order to realize continuous support, the bottom plate 19 is provided as two movable bottom plates that can be relatively away from or close to each other, and the processing support platform 1 is placed on the upper surfaces of the two movable bottom plates at the same time; The side surface of the gantry column 18 is fixedly provided with a sliding rail 23, which is distributed along the height direction of the gantry column 18, and the sliding rail 23 is provided with an electric cylinder 22, and the side surface of the bottom plate 19 is fixedly provided with a side plate 24, which is fixedly connected with the end of the electric cylinder 22 away from the sliding rail 23, and the electric cylinder 22 is distributed along the horizontal direction; During work, the winch can be used to lift the bottom plate 19, place the new processing support platform 1 at the bottom of the bottom plate 19, and then lower the bottom plate 19 until the bottom plate 19 is attached to the upper surface of the new processing support platform 1, and then start the electric cylinder 22 to pull the movable bottom plate to move outward, when the movable bottom plate is moved out from between the two corresponding processing support platforms 1, the two processing support platforms 1 are fixedly connected with each other through the corresponding tapered blocks and tapered grooves, and the purpose of automatically stacking the processing support platforms 1 up and down is achieved.

[0057] When the new processing support platform 1 is stacked on the bottom of the corresponding processing support platform 1, the bottom plate 19 is lowered to reset the bottom plate 19, and the bottom plate 19 continues to extend into the bottom of the processing support platform 1 from the bottom, and the reset operation is completed.

[0058] It should be noted that in actual use, the movable bottom plate can be provided with a slope on the side close to the middle of the processing support platform 1, which facilitates the movement of the movable bottom plate in and out of the bottom of the processing support platform 1, which is a conventional setting and will not be described here.

[0059] When the bottom plate 19 is raised and lowered, the electric cylinder 22 can also be raised and lowered on the sliding rail 23 to adapt.

[0060] It should be noted that the hollow groove 8 also has a direct current lithium battery installed therein to supply power to the electric push rod 10, which is not shown in the figure and is a conventional structure, which will not be described here.

[0061] Reference Figures 1 to 6As shown in the prior art, the machining support platform 1 is generally provided with a slot on the upper surface and a plug on the bottom. When the machining support platforms 1 are stacked, the plug on the bottom of the upper machining support platform 1 is inserted into the slot on the upper surface of the lower machining support platform 1. During the actual supporting process, the plug and the slot are easily stuck due to the large pressure of the upper machining support platform 1. When the forklift forks are used to transport the machining support platforms 1, the lower machining support platform 1 is taken off manually, which is troublesome.

[0062] Therefore, the slot 2 is arranged on the machining support platform 1, which can be a rectangular slot or a circular slot.

[0063] The slot 2 penetrates through the upper and lower surfaces of the machining support platform 1, and the nine slots 2 are arranged in a rectangular array on the machining support platform 1.

[0064] Meanwhile, the plug 3 is arranged on the lower surface of the machining support platform 1, and the nine plugs 3 are arranged in a rectangular array.

[0065] Reference Figure 7 and Figure 8 As shown in the prior art, the fixed plate 5 is arranged in the middle of the slot 2. The upper end of the slot 2 is a tapered slot, and the opening of the tapered slot gradually decreases downward. The plug 3 is arranged at the lower end of the slot 2, and the bottom of the plug 3 is a tapered block that gradually decreases from top to bottom. The tapered block is matched with the tapered slot. The second magnetic block 13 is embedded in the inside of the tapered block, and the first magnetic block 12 is embedded in the inside of the tapered slot. When the machining support platforms 1 are stacked, the corresponding tapered blocks are inserted into the tapered slots, and the first magnetic block 12 and the second magnetic block 13 repel each other to keep a gap between the tapered block and the tapered slot, which avoids the phenomenon of being stuck between the tapered block and the tapered slot. The forklift is particularly suitable for transporting the stacked machining support platforms 1. When the forklift forks are used to pick up the machining support platforms 1, the corresponding tapered blocks and the tapered slots are not stuck, and the upper machining support platform 1 can be easily separated without manual assistance to separate the machining support platforms 1, which reduces the labor cost.

[0066] In the present application, the corresponding second magnetic block 13 and the bottom plate 19 are attracted to each other and fixed, and the machining support platform 1 can be stably placed on the upper surface of the bottom plate 19.

[0067] Since the machining support platform 1 and the plug 3 are generally made of PE material, they are easily damaged during long-term transportation and use, especially the plug 3. Therefore, the plug 3 is fixed to the bottom surface of the fixed plate 5 by the screw 6, which is convenient for disassembly and replacement and reduces the use cost. When the plug 3 is damaged, it does not need to be replaced as a whole.

[0068] Further, the bottom of each pin 3 is inlaid and fixed with a pressure sensor 7, which can be used to monitor the pressure received by each pin 3, so as to judge whether the machining support platform 1 is balanced, to judge whether the stone material stack 14 on the machining support platform 1 has the possibility of falling and sliding.

[0069] The inside of the machining support platform 1 is provided with a hollow groove 8, and a counterweight assembly is arranged in the hollow groove 8. The counterweight assembly includes an electric push rod 10 and a counterweight block 11. The fixed section of the electric push rod 10 is fixedly connected to the inner wall of the machining support platform 1, and the electric push rod 10 is distributed along the width direction of the electric push rod 10. The telescopic section of the electric push rod 10 is fixedly connected with the counterweight block 11, and the counterweight block 11 is movably arranged in the hollow groove 8. When the electric push rod 10 drives the counterweight block 11 to move, the overall counterweight of the machining support platform 1 can be changed, which is used in combination with the pressure sensor 7, so that the machining support platform 1 is balanced.

[0070] Specifically, the electric push rod 10 and the pressure sensor 7 are connected through a controller. The controller is used to receive the pressure data of the pins 3 monitored by the pressure sensor 7. The 9 pressure sensors 7 respectively monitor the forces on the 9 pins 3. If the stone materials on the machining support platform 1 are placed flat, and the machining support platform 1 remains horizontal, the pressures on the 9 pins 3 should be consistent, that is, the data monitored by the 9 pressure sensors 7 are consistent. If the stone materials on the machining support platform 1 are not placed flat, or the machining support platform 1 is inclined, the forces on the 9 pins 3 will be different. When the unbalanced phenomenon reaches a certain degree, the stone materials on the machining support platform 1 are easy to fall and slide. Therefore, in actual use, a threshold range of the maximum pressure and the minimum pressure difference is set. For example, when the difference within the range of 0-20N is an acceptable difference, that is, when the maximum pressure and the minimum pressure difference monitored by the 9 pressure sensors 7 exceed the difference of 0-20N, the stone materials will have the possibility of falling and sliding. At this time, manual adjustment can be made. The counterweight assembly can also be used to change the counterweight inside the machining support platform 1, so as to automatically adjust the balance to avoid the phenomenon of stone materials falling and sliding, without manual adjustment. After adjustment, when the difference falls within the threshold range, it can be automatically judged whether it meets the transportation conditions.

[0071] It should be noted that the threshold range of the difference is determined according to the friction force of the actual transported machining support platform 1 and stone materials and other data, which can be adjusted according to actual needs.

[0072] Further, due to the arrangement of the counterweight assembly, it is particularly suitable for the case of the fork truck transporting the processing support platform 1, because the fork plate 15 of the fork truck usually has an inclination angle, so that the transported goods have a tendency to move towards the fork truck, avoiding overturning and goods falling off, therefore, the processing support platform 1 in the transporting state is inclined, and cannot be matched with too high or too many stones, otherwise the processing support platform 1 is easy to slide and fall, and the arrangement of the counterweight assembly in the present application can also adjust the balance of the inclined processing support platform 1, so that the fork truck can transport more or higher stones, improve the carrying capacity of the fork truck at one time, and reduce the transportation cost.

[0073] Further, considering that the existing processing support platform 1 is randomly placed without distinguishing the front and back surfaces to achieve the purpose of rapid placement, therefore, in order to cooperate with efficient placement, the counterweight assembly in the present application is provided with two groups, and the two groups of counterweight assemblies are arranged in the hollow groove 8 and are centrally symmetrically arranged about the center point of the processing support platform 1, no matter whether the processing support platform 1 is placed forward or backward, the balance of the processing support platform 1 can be adjusted through the corresponding counterweight assembly, and the practicability is high.

[0074] Reference Figure 14 The processing support platform 1 of the present application is shown in the figure.
