Description

Technical Field

[0001] This invention relates to the field of stone polishing equipment technology, specifically to a polishing device for artificial quartz stone slabs. Background Technology

[0002] Artificial quartz stone slabs are large-format slabs made by mixing a high proportion of quartz crystals with resin, pigments and other trace elements, and processing them under special physical and chemical conditions, as well as through processes such as negative pressure vacuum, high-frequency vibration molding, and heat curing. They are a new type of countertop material that has become popular internationally in recent years, and have advantages such as high hardness and wear resistance, high temperature resistance, stain resistance and easy cleaning.

[0003] In the traditional artificial quartz stone slab processing industry, the polishing process is a crucial step, directly affecting the final quality and market competitiveness of the product. Traditional quartz stone slab polishing is mostly done manually or semi-automatically, polishing only one slab at a time. Furthermore, the polishing process requires frequent manual intervention, resulting in low overall production efficiency and failing to meet the demands of large-scale production. In addition, manual operation is easily affected by factors such as worker skill level and fatigue, further reducing production efficiency. Summary of the Invention

Through an automated workflow, two quartz stone slabs can be polished simultaneously at different workstations, realizing parallel processing of polishing work. This greatly shortens the polishing cycle of a single slab, improves the overall production efficiency, and the automated control reduces errors caused by human factors, further improving polishing accuracy.

[0020] This invention provides a polishing device for artificial quartz stone slabs, which has the following beneficial effects:

[0021] (1) In this invention, during the quartz stone slab polishing process, two quartz stone slabs are first placed in the two limiting frames at the top of an unobstructed cross-shaped support plate. By controlling the rotation of the reciprocating screw, the transmission gear plate is moved a certain distance, causing the transmission gear to rotate the support shaft 90 degrees. This allows the cross-shaped support plate to move the two quartz stone slabs to the top automatic polishing mechanism and the slab lifting control mechanism, respectively. The top automatic polishing mechanism performs fully automatic top polishing on one of the quartz stone slabs. The slab lifting control mechanism, the transverse side polishing mechanism, and the longitudinal side polishing mechanism work together to polish the other quartz stone slab. Quartz stone slabs undergo grinding on all four sides. Through an automated workflow, two quartz stone slabs can be ground simultaneously at different workstations, achieving parallel processing of the grinding work. This significantly shortens the grinding cycle of a single slab, improves overall production efficiency, and reduces errors caused by human factors, further enhancing grinding precision. The entire grinding process requires no manual intervention, reducing the labor intensity of workers, decreasing reliance on manual labor, and lowering labor costs. Automated grinding also reduces direct contact between workers and dangerous parts such as high-speed rotating grinding wheels, lowering the risk of workplace accidents.

[0022] (2) In this invention, when the quartz stone slab moves below the grinding wheel mounting plate, the top surface grinding motor starts, driving the grinding wheel mounting plate to rotate. At the same time, the horizontal drive threaded rod is controlled by the horizontal drive motor to rotate, driving the horizontal transmission block to move. The two connecting rods drive the round plate to move laterally on the top of the quartz stone slab. At the same time, the longitudinal drive electric cylinder is controlled to start, driving the L-shaped transmission block to move reciprocating linearly. The L-shaped transmission plate drives the control box to move reciprocating linearly, thereby making the round plate move longitudinally reciprocating linearly on the top of the quartz stone slab. Thus, while the grinding wheel mounting plate rotates, it also moves longitudinally reciprocating linearly and laterally linearly, uniformly and fully grinding the top surface of the quartz stone slab. The grinding process of the top surface of the quartz stone slab is comprehensive and efficient, which can achieve fine grinding of the top surface of the quartz stone slab, reduce grinding dead corners, improve the smoothness and consistency of the ground surface, and has a high degree of automation, reducing the reliance on manual operation. This not only reduces labor intensity but also reduces errors caused by human factors.

[0023] (3) In this invention, when the quartz stone slab moves between the two clamping plates, the two cylinders are activated, and the two clamping plates move closer together to firmly clamp the quartz stone slab. By controlling the activation of the lifting drive cylinder, the U-shaped frame is driven to rise and then fall, so that the two clamping plates drive the quartz stone slab to rise and then fall. When the quartz stone slab passes through the horizontal fixing frame, the activation of the first drive motor drives the two first transmission wheels connected by the transmission belt to rotate simultaneously, thereby driving the horizontal grinding rollers to rotate simultaneously. When the quartz stone slab passes through the horizontal fixing frame, the two horizontal sides of the quartz stone slab are fully polished. During the polishing process, as the quartz stone slab passes through the longitudinal side fixing frame, the second drive motor drives two second transmission wheels connected by a transmission belt to rotate simultaneously. This causes the two longitudinal side polishing rollers to rotate at the same time, thus fully polishing the longitudinal sides of the quartz stone slab. Through the slab lifting control mechanism, the transverse side polishing mechanism, and the longitudinal side polishing mechanism, the polishing work of all four sides of the quartz stone slab can be completed in one lifting process, greatly reducing the polishing time required. Under the premise of fully and evenly polishing the sides of the quartz stone slab, the polishing efficiency is greatly improved. The entire process is automatic and requires no manual labor, resulting in low labor intensity. Attached Figure Description

[0033] Please see Figures 1-8 The present invention provides a technical solution: a polishing device for artificial quartz stone slabs, comprising:

[0034] A rotary pallet control mechanism 1 includes a base box 101, a support shaft 102, a cross-shaped pallet plate 103, a transmission gear 104, two mounting plates 105, a reciprocating screw 106, and a transmission gear plate 107. The support shaft 102 is rotatably connected to the top of the base box 101, and the lower end of the support shaft 102 extends into the interior of the base box 101. The cross-shaped pallet plate 103 is fixedly connected to the upper end of the support shaft 102. The transmission gear 104 is fixedly sleeved on the support shaft 102. The two mounting plates 105 are fixedly connected to the inner wall of one side of the base box 101. The reciprocating screw 106 is rotatably connected between the two mounting plates 105. The transmission gear plate 107 is threadedly connected to the reciprocating screw 106, and the transmission gear plate 107 is meshed with the transmission gear 104. An L-shaped support plate 2 is fixedly connected to the outer surface of one side of the base box 101.

[0035] Automatic grinding mechanism 3 for top surface is installed on the top of L-shaped support plate 2;

[0036] The plate lifting control mechanism 4 includes a support frame plate 401, which is fixedly connected to the outer surface of one side of the base box 101. Two sets of transverse fixing rods 5 are fixedly connected to the inner wall of one side of the support frame plate 401, with two rods in each set.

[0037] The transverse side grinding mechanism 6 and the longitudinal side grinding mechanism 7 are respectively set at one end of the corresponding two transverse fixed rods 5.

[0038] In this implementation scheme: The cross-shaped support plate 103 has four square openings. Four limiting frames are installed on the top of the cross-shaped support plate 103. The automatic top-surface grinding mechanism 3 is used to grind the top of the quartz stone slabs on the cross-shaped support plate 103. The slab lifting control mechanism 4, the transverse side grinding mechanism 6, and the longitudinal side grinding mechanism 7 are used to grind the four sides of the quartz stone slabs. The rotating pallet control mechanism 1 is used to precisely transport the quartz stone slabs to the automatic top-surface grinding mechanism 3 and the slab lifting control mechanism 4. During the grinding process, two quartz stone slabs are first placed in the two limiting frames on the top of the unobstructed cross-shaped support plate 103. By controlling the reciprocating screw 106 to rotate, the transmission gear plate 107 moves a certain distance, causing the transmission gear 104 to drive the support shaft 102 to rotate 90 degrees, thus moving the cross-shaped support plate 103 and the two quartz stone slabs to the top of the automatic top-surface grinding mechanism 3. At the automatic grinding mechanism 3 and the slab lifting control mechanism 4, the top surface automatic grinding mechanism 3 performs fully automatic top surface grinding on one of the quartz stone slabs. The slab lifting control mechanism 4, the transverse side grinding mechanism 6, and the longitudinal side grinding mechanism 7 work together to grind the four sides of the other quartz stone slab. After the first step of grinding is completed, the reciprocating screw 106 is controlled to continue rotating, causing the cross-shaped support plate 103 to rotate 180 degrees, and the two quartz stone slabs exchange positions. The top surface automatic grinding mechanism 3 performs top surface grinding on the quartz stone slab that has been ground on four sides, and the slab lifting control mechanism 4, the transverse side grinding mechanism 6, and the longitudinal side grinding mechanism 7 perform side grinding on the quartz stone slab that has been ground on the top surface, thereby completing the grinding work of the quartz stone slab. Through the automated workflow, the two quartz stone slabs can be ground simultaneously at different workstations, realizing parallel processing of the grinding work. This significantly shortens the sanding cycle of a single board, improves overall production efficiency, reduces errors caused by human factors through automated control, further enhances sanding precision, and eliminates the need for manual intervention throughout the sanding process, thus reducing the labor intensity of workers, decreasing reliance on manual labor, and lowering labor costs. Automated sanding also reduces direct contact between workers and dangerous parts such as high-speed rotating grinding wheels, thereby reducing the risk of workplace accidents.

[0039] Specifically, the rotary pallet control mechanism 1 also includes a servo motor 108, which is fixedly installed on one side of the outer surface of one of the mounting plates 105, and the output end of the servo motor 108 is fixedly connected to the reciprocating lead screw 106.

[0040] In this implementation scheme: by controlling the start of the servo motor 108, the reciprocating lead screw 106 can be driven to rotate. The base box 101 near the position of the servo motor 108 is provided with heat dissipation holes.

[0041] Specifically, the rotary pallet control mechanism 1 also includes two limit rods 109, both of which are fixedly connected between the inner walls of the two sides of the base box 101, and the transmission gear plate 107 is slidably sleeved on the two limit rods 109.

[0042] In this embodiment, the two limiting rods 109 enable the transmission gear plate 107 to maintain stable movement while ensuring that the transmission gear plate 107 and the transmission gear 104 remain in mesh.

[0043] Specifically, the automatic top surface grinding mechanism 3 includes a support plate 301, a longitudinal drive electric cylinder 302, an L-shaped transmission block 303, an L-shaped transmission plate 304, a control box 305, a transverse drive threaded rod 308, a transverse transmission block 309, two connecting rods 312, a circular plate 313, a top surface grinding motor 314, and a grinding wheel mounting plate 315. The support plate 301 is fixedly connected to the top of the L-shaped support plate 2, the longitudinal drive electric cylinder 302 is fixedly installed on the top of the support plate 301, the L-shaped transmission block 303 is fixedly connected to the output end of the longitudinal drive electric cylinder 302, the L-shaped transmission plate 304 is fixedly connected to one outer surface of the L-shaped transmission block 303, and the control box 305 is fixedly installed on the top of the L-shaped transmission block 303. A transverse drive threaded rod 308 is rotatably connected between the two inner walls of the control box 305 and connected to the outer surface of one side of the L-shaped transmission plate 304. A transverse transmission block 309 is threadedly connected to the transverse drive threaded rod 308. Two connecting rods 312 are fixedly connected to the bottom of the transverse transmission block 309 and slide through the bottom inner wall of the control box 305. A circular plate 313 is fixedly connected to the lower end of the two connecting rods 312. A top surface grinding motor 314 is fixedly installed on the top of the circular plate 313. A grinding wheel mounting plate 315 is rotatably connected to the bottom of the circular plate 313. The output end of the top surface grinding motor 314 is fixedly connected to the top of the grinding wheel mounting plate 315.

[0044] In this implementation scheme: Multiple grinding wheels are mounted on the bottom of the grinding wheel mounting plate 315. When the grinding wheel mounting plate 315 rotates, it drives the multiple grinding wheels to perform circular motion. When the support shaft 102 drives the cross-shaped support plate 103 to rotate, moving the quartz stone slab below the grinding wheel mounting plate 315, the top surface grinding motor 314 will start, driving the grinding wheel mounting plate 315 to rotate. Simultaneously, the transverse drive threaded rod 308 will be controlled to rotate, driving the transverse transmission block 309 to move. The two connecting rods 312 drive the circular plate 313 to move laterally on the top of the quartz stone slab. At the same time, the longitudinal drive electric cylinder 302 will be controlled to start, driving the L-shaped transmission block 303 to perform reciprocating linear motion. The L-shaped transmission plate 304 drives the control box 305 to perform reciprocating linear motion, which causes the circular plate 313 to move longitudinally and reciprocatingly on the top of the quartz stone slab. This allows the grinding wheel mounting plate 315 to rotate while simultaneously performing longitudinal reciprocating linear motion and lateral linear motion, uniformly and thoroughly polishing the top surface of the quartz stone slab. The polishing process of the top surface of the quartz stone slab is comprehensive and efficient, enabling fine polishing of the top surface of the quartz stone slab, reducing polishing dead corners, improving the smoothness and consistency of the polished surface, and achieving a high degree of automation. This reduces reliance on manual operation, not only reducing labor intensity but also reducing errors caused by human factors.

[0045] Specifically, the automatic grinding mechanism 3 for the top surface also includes two stabilizing plates 306 and three stabilizing rods 307. The two stabilizing plates 306 are fixedly connected to the top of the support plate 301, and the three stabilizing rods 307 are fixedly connected between the two stabilizing plates 306. The L-shaped transmission plate 304 is slidably sleeved on the three stabilizing rods 307.

[0046] In this implementation scheme: two stabilizing plates 306 and three stabilizing bars 307 are used to ensure that the L-shaped transmission plate 304 moves in a stable longitudinal straight line, thereby ensuring the stability of all components on the control box 305 during operation.

[0047] Specifically, the automatic grinding mechanism 3 for the top surface also includes a horizontal drive motor 310, which is fixedly installed on the outer surface of one side of the control box 305. The output end of the horizontal drive motor 310 is fixedly connected to the horizontal drive threaded rod 308.

[0048] In this implementation scheme: by controlling the start of the transverse drive motor 310, the transverse drive threaded rod 308 can be driven to rotate at a fixed speed, so that the transverse transmission block 309 drives the grinding wheel mounting plate 315 to move at a suitable speed.

[0049] Specifically, the automatic grinding mechanism 3 for the top surface also includes two horizontal support rods 311. Both horizontal support rods 311 are fixedly connected between the inner walls of the two sides of the control box 305, and the horizontal transmission block 309 is slidably sleeved on the two horizontal support rods 311.

[0050] In this embodiment: two lateral support rods 311 are used to ensure that the lateral transmission block 309 maintains stable lateral linear movement, and at the same time to support the lateral transmission block 309 and all components mounted on its bottom.

[0051] Specifically, the plate lifting control mechanism 4 also includes a lifting drive electric cylinder 402, a U-shaped plate frame 403, two cylinders 404, two clamping plates 405, and two vertical rods 406. The two vertical rods 406 are fixedly connected between the upper and lower inner walls of the support frame plate 401. The U-shaped plate frame 403 is slidably sleeved on the two vertical rods 406. The lifting drive electric cylinder 402 is fixedly installed on the bottom inner wall of the support frame plate 401, and the output end of the lifting drive electric cylinder 402 is fixedly connected to the U-shaped plate frame 403. The two cylinders 404 are respectively fixedly installed on the top and bottom of the U-shaped plate frame 403. The two clamping plates 405 are respectively fixedly connected to the output ends of the two cylinders 404.

[0052] In this implementation scheme: the clamping plate 405 can easily pass through the square opening on the cross-shaped support plate 103. When the support shaft 102 drives the cross-shaped support plate 103 to transport the quartz stone slab between the upper and lower inner walls of the U-shaped frame 403, and the position of the quartz stone slab corresponds to the horizontal side grinding mechanism 6 and the vertical side grinding mechanism 7, the two cylinders 404 will be activated, and the two clamping plates 405 will move closer together to firmly clamp the quartz stone slab. By controlling the lifting drive cylinder 402 to start, the U-shaped frame 403 will first rise and then fall, thereby making the two... The clamping plate 405 will first lift the quartz stone slab through the horizontal side polishing mechanism 6 and the vertical side polishing mechanism 7, and then lower it through the vertical side polishing mechanism 7 and the horizontal side polishing mechanism 6. Finally, the quartz stone slab will be placed back on the cross-shaped support plate 103. The two vertical rods 406 ensure that the U-shaped frame 403 only moves in the vertical plane, and ensure that the U-shaped frame 403, the horizontal side polishing mechanism 6 and the vertical side polishing mechanism 7 can always maintain cooperation. That is, the quartz stone slab clamped by the two clamping plates 405 can always pass through the horizontal side polishing mechanism 6 and the vertical side polishing mechanism 7.

[0053] Specifically, the transverse side grinding mechanism 6 includes a transverse side fixing frame 601, two transverse side grinding rollers 602, a first side receiving box 603, two first transmission wheels 604, and a first drive motor 605. The transverse side fixing frame 601 is fixedly connected to one end of the corresponding two transverse fixing rods 5. The two transverse side grinding rollers 602 are rotatably connected between the inner walls of the two sides of the transverse side fixing frame 601. The first side receiving box 603 is fixedly connected to one side of the outer surface of the transverse side fixing frame 601. The two first transmission wheels 604 are rotatably connected between the first side receiving box 603 and the transverse side fixing frame 601. The first drive motor 605 is fixedly installed on one side of the outer surface of the first side receiving box 603. The output end of the first drive motor 605 is fixedly connected to the corresponding first transmission wheel 604.

[0054] In this implementation scheme: after the two clamping plates 405 clamp the quartz stone slab, the lifting drive cylinder 402 will drive the U-shaped frame 403 to rise and then fall, thereby causing the quartz stone slab to rise. First, it passes through the horizontal fixing frame 601. Through the start of the first drive motor 605, it will drive the two first transmission wheels 604 connected by the transmission belt to rotate simultaneously, thereby driving the horizontal grinding rollers 602 to rotate simultaneously. Both horizontal grinding rollers 602 are fitted with sandpaper. When the quartz stone slab passes through the horizontal fixing frame 601, the two horizontal sides of the quartz stone slab will be fully ground.

[0055] Specifically, the longitudinal side grinding mechanism 7 includes a longitudinal side fixing frame 701, two longitudinal side grinding rollers 702, a second side receiving box 703, two second transmission wheels 704, and a second drive motor 705. The longitudinal side fixing frame 701 is fixedly connected to one end of the corresponding two transverse fixing rods 5. The two longitudinal side grinding rollers 702 are rotatably connected between the inner walls of the two sides of the longitudinal side fixing frame 701. The second side receiving box 703 is fixedly connected to one side of the outer surface of the longitudinal side fixing frame 701. The two second transmission wheels 704 are rotatably connected between the second side receiving box 703 and the longitudinal side fixing frame 701. The second drive motor 705 is fixedly installed on one side of the outer surface of the second side receiving box 703. The output end of the second drive motor 705 is fixedly connected to the corresponding second transmission wheel 704.

[0056] In this implementation scheme: the two clamping plates 405 will drive the quartz stone slab from the lower side of the longitudinal side fixing frame 701 to the upper side of the longitudinal side fixing frame 701, and then from the upper side of the longitudinal side fixing frame 701 back to the lower side of the longitudinal side fixing frame 701. During the whole process, the second drive motor 705 will drive the two second transmission wheels 704 connected by the transmission belt to rotate simultaneously, so that the two longitudinal side grinding rollers 702 rotate simultaneously. The two longitudinal side grinding rollers 702 are fitted with sandpaper, thereby fully grinding the longitudinal side of the quartz stone slab.

[0057] Working principle: Two quartz stone slabs are placed within the two limit frames at the top of the unobstructed cross-shaped support plate 103. The servo motor 108 is started, driving the reciprocating screw 106 to rotate, which in turn moves the transmission gear plate 107 a certain distance. This causes the transmission gear 104 to rotate the support shaft 102 by 90 degrees, allowing the cross-shaped support plate 103 to move the two quartz stone slabs to the top automatic grinding mechanism 3 and the slab lifting control mechanism 4, respectively. The top automatic grinding mechanism 3 grinds the quartz stone slabs as follows: The top grinding motor 314 starts, rotating the grinding wheel mounting plate 315. Simultaneously, the transverse drive threaded rod 308 is controlled by the transverse drive motor 310 to rotate, moving the transverse transmission block 309. The two connecting rods 312 move the circular plate 313 on the quartz stone... The top of the slab moves laterally, while the longitudinal drive cylinder 302 is activated, driving the L-shaped transmission block 303 to move reciprocating linearly. The L-shaped transmission plate 304 drives the control box 305 to move reciprocating linearly, thus causing the circular plate 313 to move longitudinally and reciprocating linearly on the top of the quartz stone slab. This allows the grinding wheel mounting plate 315 to rotate while simultaneously moving longitudinally and laterally, uniformly and thoroughly polishing the top surface of the quartz stone slab. The polishing process of the top surface of the quartz stone slab is comprehensive and efficient, enabling fine polishing of the top surface of the quartz stone slab, reducing polishing dead corners, improving the smoothness and consistency of the polished surface, and achieving a high degree of automation. This reduces reliance on manual operation, not only reducing labor intensity but also reducing errors caused by human factors.The polishing process of the quartz stone slab by the slab lifting control mechanism 4, the transverse side polishing mechanism 6, and the longitudinal side polishing mechanism 7 is as follows: Two cylinders 404 are activated, and two clamping plates 405 move closer together to firmly clamp the quartz stone slab. The lifting drive cylinder 402 is activated, causing the U-shaped frame 403 to rise and then fall. This causes the two clamping plates 405 to lift the quartz stone slab first, passing it through the transverse side polishing mechanism 6 and the longitudinal side polishing mechanism 7, and then lower it through the longitudinal side polishing mechanism 7 and the transverse side polishing mechanism 6. When the quartz stone slab passes through the transverse side fixing frame 601, the activation of the first drive motor 605 causes the two first transmission wheels 604, connected by a transmission belt, to rotate simultaneously. This causes the transverse side polishing rollers 602 to rotate simultaneously. Both transverse side polishing rollers 602 are fitted with sandpaper. As the quartz stone slab passes through the transverse side fixing frame 601… The two transverse sides of the quartz stone slab are thoroughly polished. When the quartz stone slab passes through the longitudinal side fixing frame 701, the second drive motor 705 drives two second transmission wheels 704 connected by a transmission belt to rotate simultaneously, causing the two longitudinal side polishing rollers 702 to rotate simultaneously. Sandpaper is fitted on the two longitudinal side polishing rollers 702, thereby thoroughly polishing the longitudinal sides of the quartz stone slab. Through the slab lifting control mechanism 4, the transverse side polishing mechanism 6, and the longitudinal side polishing mechanism 7, the polishing work of all four sides of the quartz stone slab can be completed in one lifting process, greatly reducing the polishing time required. Under the premise of fully and evenly polishing the sides of the quartz stone slab, the polishing efficiency is greatly improved. The whole process is automatic and requires no manual labor, resulting in low labor intensity. Through the automated workflow, two quartz stone slabs can be polished at different workstations at the same time, realizing parallel processing of polishing work. This significantly shortens the sanding cycle for individual boards, improves overall production efficiency, and reduces errors caused by human factors through automated control, further enhancing sanding precision. The entire sanding process requires no manual intervention, reducing worker workload, decreasing reliance on manual labor, and lowering labor costs. Automated sanding also reduces direct contact between workers and dangerous components such as high-speed rotating grinding wheels, lowering the risk of workplace injuries.
