Description

Technical Field

[0001] The present disclosure belongs to the technical field of quartz stone plate processing, and particularly relates to a chamfering device for artificial quartz stone plates. Background Art

[0002] Artificial quartz stone plates are a new type of building decoration material, widely used in multiple fields such as kitchen countertops, bathrooms, window sills, etc. Their main components are quartz sand and unsaturated polyester resin, processed through special processes, and have excellent physical and chemical properties.

[0003] In the prior art, artificial quartz stone plates are brittle materials. Although they have high hardness, they are prone to chipping when subjected to impact or uneven stress.

[0004] This phenomenon occurs more frequently in large-sized quartz stone plates because the edge length of large-sized artificial quartz stone plates is larger, making the chamfering processing time longer. Therefore, it is more likely to chip due to uneven stress during chamfering. At the same time, the long cutting working hours will also cause the temperature of the edge of the artificial quartz stone plate to rise, which may affect the resin component inside the artificial quartz stone plate, resulting in a decline in surface quality or the appearance of cracks, and thus more likely to chip, greatly increasing the processing difficulty of large-sized artificial quartz stone plates. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to provide a chamfering device for artificial quartz stone plates, which can reduce the probability of chipping during chamfering of artificial quartz stone plates, improve the chamfering efficiency of artificial quartz stone plates, and thus greatly reduce the processing cost of artificial quartz stone plates.

[0006] To solve the above problems, the present invention provides a chamfering device for artificial quartz stone plates, comprising: A base, on the top of which a working groove for storing water is provided; A chamfering assembly, which is slidably arranged on the top of the base and is used for cutting artificial quartz stone plates; A positioning assembly, which is arranged inside the base and is used for fixing artificial quartz stone plates. The positioning assembly includes a sliding table, an air pump, and an air duct. The sliding table is slidably connected in the working groove. The sliding table is hollow inside and provided with a pressure chamber. A water tank is opened upward at the bottom of the sliding table outside the pressure chamber. An air inlet communicating with the pressure chamber is opened at the top of the sliding table. An overflow hole communicating with the water tank is processed at the top edge position of the sliding table. The air pump is installed at the bottom of the base. The air inlet end of the air pump is fixedly connected with an air duct, and the air duct sequentially penetrates through the base and the sliding table and extends into the pressure chamber.

[0007] Further, mounting grooves are formed on the outer walls of the front and rear sides of the base. The top and bottom of the mounting grooves communicate with the working chamber through through grooves. A cover plate is hinged to the bottom of the opening position of the mounting groove. A groove is machined on the inner side of the cover plate, so that a flow channel for overflow water is formed between the through groove and the groove.

[0008] Further, a partition is connected in the groove. A filter screen is arranged in the partition. A retaining piece for blocking the filter screen is hinged to the bottom of the partition directly below the filter screen.

[0009] Further, the inner top wall of the groove is fixedly connected with a sleeve. A connecting rod is slidably connected in the sleeve. The bottom of the connecting rod extends out of the sleeve and is fixedly connected with the partition. A limiting ring is fixedly connected to the outer wall of the connecting rod. A sliding groove for the limiting ring to slide is formed in the sleeve. A compression spring is fixedly connected between the bottom of the limiting ring and the sliding groove.

[0010] Further, the air outlet end of the air pump is fixedly connected with a transfer chamber. An exhaust pipe is fixedly connected to the outer wall of the transfer chamber. One end of the exhaust pipe away from the transfer chamber is connected to the top of the outer wall of the sleeve, so that the transfer chamber communicates with the top of the sliding groove. A one-way valve for air reflux is connected to the side wall of the transfer chamber.

[0011] Further, a limiting block is fixedly connected to the bottom of the partition at the hinge position of the retaining piece. A limiting portion is formed by a protrusion on the bottom side wall of the limiting block close to the retaining piece, so that the opening angle of the retaining piece is less than 45 degrees after being resisted by the limiting portion.

[0012] Further, circular grooves are formed at the four corners of the bottom of the sliding table. Support springs are connected to the bottom wall of the working groove in the circular grooves respectively.

[0013] Further, a sleeve is slidably connected in the air inlet. A rubber pad that fits the artificial quartz stone plate is fixedly connected to the top of the sleeve. The bottom of the outer wall of the sleeve is concave, and the top of the inner wall of the air inlet is concave, so that a connecting groove is jointly formed between the sleeve and the air inlet. A connecting spring for connecting the sleeve and the air inlet is arranged in the connecting groove.

[0014] Further, the chamfering assembly includes an X-axis driver, a Y-axis driver and a cutting machine. Track grooves are formed on the left and right sides of the top of the base. The X-axis driver is arranged in the track groove. A support column is connected to the X-axis driver. A Y-axis driver is fixedly connected between the two support columns. The cutting machine is slidably connected to the bottom of the Y-axis driver. Beneficial effects

[0015] 1. The chamfering device for artificial quartz stone plates, through the set positioning component, after the artificial quartz stone plate is placed on the top of the sliding table, the artificial quartz stone plate can be fixed by the negative pressure generated by the air pump pumping air, making the subsequent chamfering more stable, improving the chamfering effect of the artificial quartz stone plate. At the same time, due to the air pump pumping air, the sliding table will sink into the working groove under the action of atmospheric pressure, thereby squeezing out the water at the bottom of the working groove, making the surface of the artificial quartz stone plate wetted by water. Under the covering of water, the heat generated when the chamfering component cuts the artificial quartz stone plate will be taken away by the water flow, which can avoid the resin component in the artificial quartz stone plate from being affected by high temperature resulting in a decline in surface quality or cracks, reducing the risk of chipping. At the same time, the lubricating effect of water can reduce the friction generated during the cutting process, making the cutting smoother, thereby further reducing the risk of chipping and effectively improving the chamfering efficiency of large-size artificial quartz stone plates; 2. The chamfering device for artificial quartz stone plates, through the set installation groove, through groove and cover plate, when the water is about to overflow, the water can be stored between the installation groove and the groove through the through groove at the top of the installation groove. When the sliding table resets, the through groove at the bottom of the installation groove opens, and at this time, the water stored between the installation groove and the groove will flow back, which can effectively avoid waste caused by water overflow while ensuring that the water can completely cover the surface of the artificial quartz stone plate; 3. The chamfering device for artificial quartz stone plates, through the set partition board and filter screen, after the water passes through the partition board, the debris carried in the water will be intercepted by the filter screen, thereby avoiding the pollution of the water in the working groove. When it is necessary to clean the artificial quartz stone plates after continuous processing, the cover plate can be directly opened to clean the filter screen, which can effectively improve the cleaning efficiency.

[0029] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention and are not used to limit the present invention.

[0030] Referring to Figures 1-8 As shown, according to Embodiment 1 of the present invention, a chamfering device for artificial quartz stone plates is provided, including: A base 1, on the top of which a working groove 4 for storing water is provided; A chamfering assembly 2, which is slidably arranged on the top of the base 1 and is used for cutting artificial quartz stone plates; A positioning assembly 3, which is arranged inside the base 1 and is used for fixing artificial quartz stone plates. The positioning assembly 3 includes a sliding table 301, an air pump 302 and an air duct 303. The sliding table 301 is slidably connected in the working groove 4. A pressure chamber 5 is provided in the sliding table 301 in a hollow manner. A water tank 6 is provided upward at the bottom of the sliding table 301 outside the pressure chamber 5. An air inlet 7 communicating with the pressure chamber 5 is provided at the top of the sliding table 301. An overflow hole 8 communicating with the water tank 6 is processed at the top edge position of the sliding table 301. The air pump 302 is installed at the bottom of the base 1. The air inlet end of the air pump 302 is fixedly connected with an air duct 303, and the air duct 303 sequentially penetrates through the base 1 and the sliding table 301 and extends into the pressure chamber 5.

[0031] In this embodiment, it can be observed that Figure 1 by providing the base 1, the chamfering assembly 2 is slidably connected to the top of the base 1, and a controller 34 is installed on the side wall of the base 1, which can be used to control the chamfering assembly 2 to chamfer the artificial quartz stone plate placed on the base 1 through the controller 34, so as to realize the function of processing artificial quartz stone plates.

[0032] When processing artificial quartz stone plates, it is necessary to fix the artificial quartz stone plates to avoid the offset of the artificial quartz stone plates during the chamfering process, which affects the chamfering operation. Therefore, Figure 1 it can also be found that a positioning component 3 is provided at the center of the top of the base 1. After placing the artificial quartz stone plate at this time, the artificial quartz stone plate can be fixed by the positioning component 3, which can make the chamfering effect of the artificial quartz stone plate better.

[0033] Since the edge length of large-size artificial quartz stone plates is relatively large, the chamfering processing time is longer. Therefore, it is easier to break the edge due to uneven stress during chamfering. At the same time, the long cutting time will also cause the temperature of the edge of the artificial quartz stone plate to rise, which may affect the resin component in the artificial quartz stone plate, resulting in a decline in surface quality or cracks, and thus it is more likely to break the edge, greatly increasing the processing difficulty of large-size artificial quartz stone plates.

[0034] Therefore, in order to avoid the edge breaking of the artificial quartz stone plate during chamfering, observing Figure 3 it can be found that a working groove 4 for storing water is opened at the top of the base 1. At the same time, the positioning component 3 mainly consists of a sliding table 301, an air pump 302 and an air duct 303. The sliding table 301 is slidably connected in the working groove 4. A pressure chamber 5 is provided in the middle of the sliding table 301. A water tank 6 is opened upward at the bottom of the sliding table 301 outside the pressure chamber 5. An air inlet 7 communicating with the pressure chamber 5 is opened at the top of the sliding table 301. An overflow hole 8 communicating with the water tank 6 is processed at the edge position of the top of the sliding table 301. The air pump 302 is installed at the bottom of the base 1. The air inlet end of the air pump 302 is fixedly connected with an air duct 303. The air duct 303 sequentially penetrates through the base 1 and the sliding table 301 and extends into the pressure chamber 5.

[0035] At this time, when the artificial quartz stone plate is placed on the top of the sliding table 301, the air pump 302 can be started, so that the air pump 302 extracts the air in the pressure chamber 5 through the air duct 303. At this time, the air inlet 7 is blocked by the artificial quartz stone plate and cannot intake air. Therefore, the air extraction of the air pump 302 will make the pressure chamber 5 in a low-pressure state, so that the artificial quartz stone plate is adsorbed and fixed by the negative pressure of the air inlet 7. Subsequently, under the action of the external air pressure, the sliding table 301 will be pressed down to the bottom of the working groove 4, thereby squeezing the space at the bottom of the working groove 4, greatly reducing the space originally containing water.

[0036] As the sliding table 301 moves downward, the water that originally converged at the bottom of the working groove 4 will enter the water tank 6 and finally overflow through the overflow holes 8 opened at the top edge position of the sliding table 301, filling the working groove with water. At this time, the artificial quartz stone plate in the working groove 4 will sink into the water. Under the covering of water, the top of the artificial quartz stone plate will be subjected to the pressure of part of the water, which can further improve the positioning effect of the artificial quartz stone plate and make the chamfering more stable. The presence of water can also cause the heat generated when the chamfering assembly 2 cuts the artificial quartz stone plate to be carried away by the water flow, avoiding the surface quality of the artificial quartz stone plate from decreasing or cracking due to the high temperature of the resin component inside, reducing the risk of chipping; at the same time, the lubricating effect of water can reduce the friction generated during the cutting process, making the cutting smoother, thereby further reducing the risk of chipping and effectively improving the chamfering efficiency of large-size artificial quartz stone plates.

[0037] Moreover, since the artificial quartz stone plate sinks underwater, when the saw blade of the chamfering assembly 2 cuts the artificial quartz stone plate, the heat generated by the saw blade will also be carried away by the water, keeping the saw blade in the best working state, reducing tool wear, and thus improving the smoothness and accuracy of cutting. This is particularly important for quartz stone plates that require fine processing, ensuring that the cutting edge is smooth and free of burrs. At the same time, due to the presence of water, a large amount of dust will not be generated during the cutting process of the artificial quartz stone plate, creating a safer working environment, keeping the working area clean, and reducing the workload of subsequent cleaning.

[0038] Finally, after the artificial quartz stone plate is cut, the air pump 302 can be turned off through the controller 34. The air pump 302 is of a type that allows gas to flow back naturally after the pump stops, such as a centrifugal pump or a screw pump without a check valve. After the air pump 302 stops, the blades in the air pump 302 no longer force the air to flow. At this time, the air can slowly flow back through the gap in the air pump 302, so that the pressure in the pressure chamber 5 is restored, and the suction force exerted by the air inlet 7 on the artificial quartz stone plate is weakened, facilitating the easy removal of the artificial quartz stone plate. And in order to ensure that the removal of the artificial quartz stone plate is not affected by the water resistance, Figure 3 it can also be found that round grooves 25 are opened at the four corners of the bottom of the sliding table 301, and the round grooves 25 are all connected to the bottom wall of the working groove 4 through support springs 26. At this time, when the pressure in the pressure chamber 5 weakens, the pressure on the support springs 26 will also weaken. Thus, under the push of the support springs 26, the sliding table 301 can be pushed back to its original position, making the artificial quartz stone plate float out of the water surface and further reducing the unloading difficulty of the artificial quartz stone plate.

[0039] After the sliding table 301 moves upward, as the water storage space at the bottom of the working tank 4 increases, most of the water will flow back through the overflow holes 8, leaving only a small amount of water and cutting debris of the artificial quartz stone plate at the top of the working tank 4, making the subsequent cleaning simpler and more convenient.

[0040] Among them, the above-mentioned controller 34 is a PLC programmable controller 34, which is a relatively mature solution for controlling electrical equipment in the prior art, so it will not be elaborated here.

[0041] In a further preferred embodiment of the present invention, when the sliding table 301 sinks, the water at the bottom of the working tank 4 will be squeezed above the sliding table 301 and used to soak the artificial quartz stone plate. This will cause waste of water when there is too much water stored in the working tank 4, and when there is less water stored in the working tank 4, the water cannot completely cover the surface of the artificial quartz stone plate, affecting the processing of the artificial quartz stone plate.

[0042] Therefore, it can be observed that Figure 5 installation grooves 9 are formed on the outer walls of the front and rear sides of the base 1. The top and bottom of the installation grooves 9 are communicated with the working cavity through through grooves 10. A cover plate 11 is hinged to the bottom of the opening of the installation groove 9, and a groove 12 is machined on the inner side of the cover plate 11, so that a flow channel for overflow water is formed between the through groove 10 and the groove 12.

[0043] At this time, when the water is about to overflow, the water will be stored between the installation groove 9 and the groove 12 through the through groove 10 at the top of the installation groove 9. After the sliding table 301 resets, the through groove 10 at the bottom of the installation groove 9 is opened, and the water stored between the installation groove 9 and the groove 12 will flow back, effectively avoiding waste caused by water overflow and ensuring that the water can completely cover the surface of the artificial quartz stone plate.

[0044] In a further preferred embodiment of the present invention, when cutting the artificial quartz stone plate, in addition to large debris, some fine particles will be generated. These particles will be carried by the surging water into the installation groove 9 and the groove 12 when processing the next artificial quartz stone plate, and finally flow back to the bottom of the working tank 4, resulting in pollution of the water at the bottom of the working tank 4.

[0045] Therefore, it can be observed that Figure 5 a partition plate 13 is connected in the groove 12. Then, looking further Figure 6 , a filter screen 14 is arranged in the partition plate 13, so that after the water passes through the partition plate 13, the debris carried in the water is intercepted by the filter screen 14, thus avoiding pollution of the water in the working tank 4. When it is necessary to clean the artificial quartz stone plate after continuous processing, the cover plate 11 can be opened as shown in Figure 2 the state to clean the filter screen 14, effectively improving the cleaning efficiency.

[0046] Finally, since the bottom of the installation groove 9 is also connected to the working groove 4 through the through groove 10, when the sliding table 301 moves downward, a large amount of water will enter between the installation groove 9 and the groove 12 through the through groove 10, thus affecting the water covering the surface of the artificial quartz stone plate. Therefore, in Figure 6 it can be found that a baffle 15 for blocking the filter screen 14 is hinged at the bottom of the partition plate 13 directly below the filter screen 14. At this time, the upwelling of water will push the baffle 15 to block the filter screen 14 area, which can effectively prevent a large amount of water from entering the installation groove 9 and the groove 12, thus ensuring that the water can stably cover the surface of the artificial quartz stone plate.

[0047] In a further preferred embodiment of the present invention, since it is necessary to make the baffle 15 block the filter screen 14 and the water needs to apply sufficient water pressure to the baffle 15, which will affect the use stability of the baffle 15. Therefore, observing Figure 7 it can be found that a sleeve 16 is fixedly connected to the inner top wall of the groove 12, a connecting rod 17 is slidably connected in the sleeve 16, and the bottom of the connecting rod 17 extends out of the sleeve 16 and is fixedly connected to the partition plate 13. At this time, when the sliding table 301 moves downward, the connecting rod 17 will also synchronously push the partition plate 13 downward, so that the baffle 15 at the bottom of the partition plate 13 moves downward. At this time, the water will apply greater pressure to the baffle 15 to ensure the use stability of the baffle 15.

[0048] Subsequently, further observing Figure 7 it can be found that a limiting ring 18 is fixedly connected to the outer wall of the connecting rod 17, a sliding groove 19 for the limiting ring 18 to slide is opened in the sleeve 16, a compression spring 20 is fixedly connected between the bottom of the limiting ring 18 and the sliding groove 19, and an exhaust pipe 22 is fixedly connected to the top of the side wall of the connecting rod 17. At this time, combined with Figure 5 it can be seen that the air outlet end of the air pump 302 is fixedly connected to a transfer chamber 21, and one end of the exhaust pipe 22 away from the connecting rod 17 is connected to the transfer chamber 21, so that the transfer chamber 21 is communicated with the top of the sliding groove 19. At this time, the air pumped out of the pressure chamber 5 by the air pump 302 will enter the sliding groove 19 through the exhaust pipe 22, increasing the air pressure above the limiting ring 18, thereby pushing the limiting ring 18 to drive the connecting rod 17 to move downward to realize the downward movement of the partition plate 13, so as to ensure that when the sliding table 301 moves downward, the water in the working groove 4 will not enter the installation groove 9 and the groove 12 in large quantities.

[0049] When the top end of the connecting rod 17 slides into the sliding groove 19, the top of the sleeve 16 will be in an open state. At this time, the air pumped into by the air pump 302 will be discharged through the top of the sleeve 16 to ensure the stability of the low pressure pumped in the pressure chamber 5.

[0050] Finally, when the air pump 302 stops operating or the slide 301 moves to the bottom of the working tank 4 and the air pump 302 can no longer pump air, a large amount of air will not enter the chute 19. At this time, under the push of the compression spring 20, the connecting rod 17 and the partition 13 can be reset to ensure the stability of the next use.

[0051] Due to the setting of the transfer bin 21, after the air pump 302 stops operating, the air cannot flow back naturally, which will affect the reset of the slide 301. Therefore, Figure 5 As can be seen in [description of the figure], a one-way valve 33 for air reflux is connected to the side wall of the transfer bin 21. After the air pump 302 stops operating, the air will enter through the one-way valve 33 to ensure the stability of the reset of the slide 301.

[0052] In a further preferred embodiment of the present invention, since the baffle 15 has weight, it will open under the action of gravity when not under force, resulting in the baffle 15 being perpendicular to the partition 13. At this time, when the baffle 15 is disturbed by water flow, it may reverse and affect the shielding of the filter screen 14. Therefore, Figure 6 It can be found that a limiting block 23 is fixedly connected to the bottom of the partition 13 at the hinge position of the baffle 15. A limiting portion 24 is formed by a protrusion on the side wall of the limiting block 23 close to the baffle 15, so that the opening angle of the baffle 15 is less than 45 degrees after being resisted by the limiting portion 24, which can effectively ensure the use stability of the baffle 15. At the same time, in order to ensure the efficient flow of water above the partition 13 through the filter screen 14, the opening angle of the baffle 15 is about 30 degrees to ensure the efficient reflux of water in the groove 12 and the installation groove 9.

[0053] In a further preferred embodiment of the present invention, since the artificial quartz stone plate cannot be made absolutely flat, there will be a gap between the surface of the artificial quartz stone plate and the surface of the slide 301, resulting in a small amount of liquid entering the pressure chamber 5 through the air inlet 7 when the air inlet 7 sucks air, affecting the use stability of the slide 301.

[0054] Therefore, Figure 8 It can be found that a sleeve 27 is slidably connected in the air inlet 7. A rubber pad 28 that fits the artificial quartz stone plate is fixedly connected to the top of the sleeve 27. The bottom of the outer wall of the sleeve 27 is concave, and the top of the inner wall of the air inlet 7 is concave, so that a connecting groove 29 is jointly formed between the sleeve 27 and the air inlet 7. A connecting spring 30 for connecting the sleeve 27 and the air inlet 7 is arranged in the connecting groove 29.

[0055] At this time, when the artificial quartz stone plate is placed on the surface of the sliding table 301, it will first come into contact with the rubber pad 28 at the top of the sleeve 27. Subsequently, under the extrusion of the artificial quartz stone plate, the rubber pad 28 deforms and fits on the surface of the artificial quartz stone plate. At this time, when the air inlet 7 sucks air, the artificial quartz stone plate can be directly adsorbed and fixed, which can improve the anti-leakage performance and enhance the fixing strength of the artificial quartz stone plate at the same time.

[0056] Finally, after the air pump 302 is shut down, as the pressure in the pressure chamber 5 recovers, the suction force on the artificial quartz stone plate weakens. At this time, the connecting spring 30 will push the sleeve 27 upward, thereby lifting the artificial quartz stone plate to separate the artificial quartz stone plate from the sliding table 301, which can further improve the unloading efficiency of the artificial quartz stone plate.

[0057] In a further preferred embodiment of the present invention, as Figure 1 shown, by making the chamfering assembly 2 include an X-axis driver 201, a Y-axis driver 202 and a cutting machine 203, track grooves 31 are respectively opened on the left and right sides of the top of the base 1. The X-axis driver 201 is arranged in the track groove 31. A support column 32 is connected to the X-axis driver 201. A Y-axis driver 202 is fixedly connected between the two support columns 32. The cutting machine 203 is slidably connected to the bottom of the Y-axis driver 202. The cutting machine 203 can be controlled by the X-axis driver 201 to move along the X-axis, and the cutting machine 203 can be controlled by the Y-axis driver 202 to move along the Y-axis, so as to chamfer the four sides of the artificial quartz stone plate.

[0058] Among them, the above X-axis driver 201 and Y-axis driver 202 both adopt the moving mode of an electric motor driving a lead screw to make a slider linearly slide along a slide rail, which will not be elaborated here.

[0059] The implementation principle of the above embodiment is: place the artificial quartz stone plate on the surface of the sliding table 301, and then start the air pump 302 through the controller 34 to extract the air in the pressure chamber 5. Under the action of atmospheric pressure, the sliding table 301 will move downward, so that the water at the bottom of the working groove 4 is squeezed out and covers the surface of the artificial quartz stone plate. Finally, the chamfering assembly 2 can be started to chamfer the artificial quartz stone plate.

[0060] After chamfering, the chamfering assembly 2 is reset through the controller 34, and at the same time the air pump 302 is shut down. At this time, since the air pump 302 adopts a type that allows gas to flow back naturally through the gap after the pump stops, such as a centrifugal pump or a screw pump without a check valve installed, after the air pump 302 stops, the blades in the air pump 302 no longer forcibly push the air to flow. At this time, the air can slowly flow back through the gap in the air pump 302, so that the pressure in the pressure chamber 5 recovers, and the suction force exerted by the air inlet 7 on the artificial quartz stone plate weakens, so that the artificial quartz stone plate can be easily taken out.

[0061] It is easy for those skilled in the art to understand that, on the premise of no conflict, the above advantageous ways can be freely combined and superimposed.

[0062] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention. The above is only the preferred implementation manner of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and variations can still be made, and these improvements and variations should also be regarded as within the protection scope of the present invention.
