Description

Technical Field

[0001] This invention relates to the field of artificial quartz stone slab processing technology, specifically to a vibration and pressing device for processing artificial quartz stone slabs. Background Technology

[0002] Artificial quartz stone is composed of over 90% natural quartz and approximately 10% colorants, resins, and other additives for bonding and curing. It is produced through a process involving negative pressure vacuum molding, high-frequency vibration, and heat curing (the temperature varies depending on the type of curing agent). In the processing of artificial quartz stone, powder is first laid in a mold, then compacted using a vibration pressing device. The mold and the compacted powder are then fed into a drying machine to harden and shape the artificial quartz stone slab.

[0003] Existing vibratory pressing devices for processing artificial quartz stone slabs, while capable of vibrating and pressing the powdered material, have drawbacks. After vibrating and pressing a set of slabs, the slabs and templates need to be replaced. Material handling (removing and releasing material) is required before the device can continue operating, resulting in prolonged downtime during template replacement. This leads to low efficiency and inconvenience. Therefore, we propose a vibratory pressing device for processing artificial quartz stone slabs to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide a vibration and pressing device for processing artificial quartz stone slabs, so as to solve the problems currently found in the market as mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a vibratory pressing device for processing artificial quartz stone slabs, comprising a frame, wherein processing grooves are symmetrically passed through both sides of the frame, and the bottom of the frame is supported by support legs, wherein...

[0006] The support leg is fixedly connected to a support base near the bottom. A sealing gasket is installed on the inner wall of the processing groove. A traveling frame is slidably installed on the top of the frame. The traveling frame is driven by a drive mechanism to slide on the frame. First hydraulic rods are symmetrically installed on the inside of both sides of the traveling frame. A sealing cover is installed at the bottom of the first hydraulic rod. An air extraction pipe is connected to the top of one side of the sealing cover. A second hydraulic rod is installed on the inner side of the traveling frame near the middle.

[0007] The second hydraulic rod is fitted with a pressure plate at its bottom end inside the sealing cover. Vibration motors are symmetrically installed on the top of both sides of the pressure plate. A mold table is set at the position of the processing groove. The bottom four corners of the mold table are supported by a third hydraulic rod. The bottom end of the third hydraulic rod is connected to the support base. The top four sides of the mold table are symmetrically provided with clamping block slots. The clamping block slots are inclined and the bottom of the clamping block slots is inclined downward towards the edge of the mold table. A clamping block is slidably arranged in the clamping block slot. When the third hydraulic rod controls the mold table, it drives the clamping blocks to move closer or further away from each other synchronously through the transmission mechanism.

[0008] The transmission mechanism includes a turntable groove. The mold table has a turntable groove inside. A turntable is rotatably connected in the turntable groove. The bottom of the clamping block groove is connected to the turntable groove through a sliding rod groove. The turntable has a first transmission groove corresponding to the position of the clamping block groove. The first transmission groove is an arc-shaped groove. A sliding rod is fixedly connected to the bottom of the clamping block at the point where the first transmission groove and the sliding rod groove overlap. A rotating column is fixedly connected to the bottom of the turntable. The turntable is rotatably connected to the mold table through the rotating column. Second transmission grooves are symmetrically opened on both sides of the rotating column. The second transmission grooves are spiral-shaped. A fixed frame is fixedly connected to the top of both sides of the support base corresponding to the rotating column. A fixed rod is fixedly connected to one side of the fixed frame corresponding to the second transmission groove.

[0009] Preferably, the drive mechanism includes a slide groove, with slide grooves symmetrically opened on the top of both sides of the frame, a slider fixedly connected to the bottom of the slide groove of the walking frame, a lead screw rotatably connected inside the slide groove, and a servo motor installed at the outer end of the frame corresponding to the slide groove, with the shaft end of the servo motor fixedly connected to the lead screw.

[0010] Preferably, the slide groove is arranged parallel to the long side of the frame, and both the slide groove and the slider are T-shaped, and the slider and the lead screw are connected by a thread.

[0011] Preferably, the sealing cover and the mold table are sealed by a sealing gasket after entering the processing groove.

[0012] Preferably, the connection between the second hydraulic rod telescopic section and the sealing cover is sealed by a sealing ring.

[0013] Preferably, the mold table has guide grooves symmetrically formed on the inner walls of both sides corresponding to the clamping block groove, and a guide block is fixedly connected to one side of the clamping block corresponding to the guide groove.

[0014] Preferably, the inner width of the first transmission groove matches the outer diameter of the slide rod.

[0015] Preferably, the inner width of the second transmission groove matches the outer diameter of the fixed rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. This invention, through two processing slots set on the frame, allows for the simultaneous vibration and pressing of template powder on one set of mold tables while the other set of mold tables moves downwards, causing the template to move out of the processing slots. The template on the other set of mold tables is then replaced via a material handling and feeding device. Combined with the lateral sliding of the vibration and pressing structure, the templates on the two sets of mold tables are alternately vibrated and pressed. This allows for the simultaneous processing of one set of artificial quartz stone slabs and replacement of another set, preventing the vibratory press from stopping during slab replacement. This effectively improves the continuity of the vibration and pressing device's operation and increases the processing efficiency of artificial quartz stone slabs.

[0018] 2. In this invention, while the third hydraulic rod drives the mold platform to rise and fall, the mold platform drives the rotating column to rise and fall synchronously. The rotating column can be driven to rotate through the second transmission groove and the fixed rod, which in turn drives the turntable to rotate. When the turntable rotates, the clamping blocks can be driven to move within the clamping block groove through the first transmission groove and the sliding rod. Thus, the clamping blocks can be driven to move closer or further apart synchronously through the rise and fall of the mold platform. When the clamping blocks move further apart, the clamping blocks gradually descend through the inclined clamping block groove until the top of the clamping blocks is below the top of the mold platform, making the top of the mold platform flat. This avoids the protruding clamping blocks causing obstruction when changing the template. When it is necessary to squeeze the powder in the template, the mold platform is raised, and the clamping blocks move closer to each other synchronously. At the same time, the clamping blocks rise and can clamp the four sides of the template, which can position the template and prevent the placed template from shifting. The template is automatically positioned when it rises, so that the powder in the template can be vibrated and compressed later. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example:

[0029] Please see Figures 1 to 7 This invention provides a technical solution: a vibratory pressing device for processing artificial quartz stone slabs, comprising a frame 1, with processing grooves 2 symmetrically extending through both sides of the frame 1, and the bottom of the frame 1 supported by support legs 3, wherein...

[0030] A support base 4 is fixedly connected to the lower part of the support leg 3. A sealing gasket 5 is installed on the inner wall of the processing groove 2. A traveling frame 6 is slidably installed on the top of the frame 1. The traveling frame 6 is driven by the drive mechanism to slide on the frame 1. A first hydraulic rod 11 is symmetrically installed on the inside of both sides of the traveling frame 6. A sealing cover 12 is installed at the bottom of the first hydraulic rod 11. An air extraction pipe 13 is connected to the top of one side of the sealing cover 12. A second hydraulic rod 14 is installed on the inner side of the traveling frame 6 near the middle.

[0031] The second hydraulic rod 14 is located inside the sealing cover 12 and a pressure plate 15 is installed at its bottom end. Vibration motors 16 are symmetrically installed on the top of both sides of the pressure plate 15. A mold table 17 is set at the position of the processing groove 2. The bottom four corners of the mold table 17 are supported by a third hydraulic rod 18. The bottom end of the third hydraulic rod 18 is connected to the support base 4. The top four sides of the mold table 17 are symmetrically provided with clamping block grooves 19. The clamping block grooves 19 are inclined and the bottom of the clamping block grooves 19 is inclined downward towards the edge of the mold table 17. A clamping block 20 is slidably arranged in the clamping block groove 19. When the third hydraulic rod 18 controls the mold table 17, it drives the clamping blocks 20 to move closer or further away from each other synchronously through the transmission mechanism.

[0032] The transmission mechanism includes a turntable groove 23. The mold table 17 has a turntable groove 23 inside. A turntable 24 is rotatably connected inside the turntable groove 23. The bottom of the clamping block groove 19 is connected to the turntable groove 23 through a sliding rod groove 25. The turntable 24 has a first transmission groove 26 corresponding to the position of the clamping block groove 19. The first transmission groove 26 is an arc-shaped groove. The bottom of the clamping block 20, corresponding to the overlap of the first transmission groove 26 and the sliding rod groove 25, is fixedly connected to a sliding rod 27. The bottom end of the turntable 24 is fixedly connected to a rotating column 28. The turntable 24 is rotatably connected to the mold table 17 through the rotating column 28. The two sides of the rotating column 28 have symmetrically opened second transmission grooves 29. The second transmission grooves 29 are spiral-shaped. The support base 4 has a fixed frame 30 fixedly connected to the top of both sides of the rotating column 28. The fixed frame 30 has a fixed rod 31 fixedly connected to one side of the second transmission groove 29.

[0033] Two processing slots 2 are set on the frame 1, and the mold tables 17 on both sides are raised and lowered alternately by the third hydraulic rod 18. After the template with powder is placed on the mold table 17, the third hydraulic rod 18 moves the template upward, so that the template moves into the processing slot 2. At the same time, the servo motor 10 drives the lead screw 9 to rotate, so that the lead screw 9 drives the traveling frame 6 to move directly above the processing slot 2 through the slider 8. The first hydraulic rod 11 and the second hydraulic rod 14 drive the sealing cover 12 and the pressure plate 15 to descend synchronously. After the processing slot 2 is sealed by the sealing cover 12, the air extraction equipment creates a negative pressure state in the processing slot 2 through the air extraction pipe 13, which can effectively remove the air in the powder in the template. The second hydraulic rod 14 continues to drive the pressure plate 15 downward to compress the powder. In conjunction with the vibration motor 16, the powder can be compressed and compacted. At the same time, another set of mold tables 17 moves downward to move the template out of the processing groove 2. Through the material picking and feeding equipment, the template on the other set of mold tables 17 is replaced. In conjunction with the lateral sliding of the vibration pressing structure, the templates on the two sets of mold tables 17 are alternately vibrated and pressed. This allows for the processing of one set of artificial quartz stone slabs while replacing another set of artificial quartz stone slabs. This avoids the vibration press stopping during the replacement of artificial quartz stone slabs, effectively improving the continuity of the vibration pressing device and increasing the processing efficiency of artificial quartz stone slabs.

[0034] Please see Figures 1 to 7The drive mechanism includes a slide groove 7. Slide grooves 7 are symmetrically opened on the top of both sides of the frame 1. A slider 8 is fixedly connected to the bottom of the sliding groove 7 of the traveling frame 6. A lead screw 9 is rotatably connected inside the slide groove 7. A servo motor 10 is installed on the outer end of the frame 1 corresponding to the slide groove 7. The shaft end of the servo motor 10 is fixedly connected to the lead screw 9. The slide groove 7 is parallel to the long side of the frame 1. Both the slide groove 7 and the slider 8 are T-shaped. The slider 8 and the lead screw 9 are threadedly connected. When the servo motor 10 is working, it drives the lead screw 9 to rotate. The lead screw 9 drives the traveling frame 6 to move through the slider 8. Through the drive mechanism, the traveling frame 6 is driven to move laterally to alternately process the workpieces in the two processing slots 2.

[0035] Please see Figures 1 to 7 After the sealing cover 12 and the mold table 17 enter the processing groove 2, they are sealed by the sealing gasket 5. The connection between the extension section of the second hydraulic rod 14 and the sealing cover 12 is sealed by the sealing ring. After the mold table 17 rises and drives the template into the processing groove 2, the sealing gasket 5 seals the mold table 17 and the inner wall of the processing groove 2. After the sealing cover 12 moves downward, the sealing gasket 5 seals the sealing cover 12 and the inner wall of the processing groove 2. With the sealing ring at the connection between the extension section of the second hydraulic rod 14 and the sealing cover 12, a closed space can be formed in the processing groove 2 so that the air in the processing groove 2 can be extracted, thereby improving the vibration and pressure effect on the artificial quartz stone slab.

[0036] Please see Figures 1 to 7 The mold table 17 has guide grooves 21 symmetrically opened on both sides of the inner wall of the clamping block groove 19. The clamping block 20 is fixedly connected to the guide block 22 on one side of the guide groove 21. When the clamping block 20 moves in the clamping block groove 19, the clamping block 20 drives the guide block 22 to move in the guide groove 21. The movement of the clamping block 20 can be limited by the guide groove 21 and the guide block 22 to prevent the movement of the clamping block 20 from deviating.

[0037] Please see Figures 1 to 7The inner width of the first transmission groove 26 matches the outer diameter of the slide rod 27, and the inner width of the second transmission groove 29 matches the outer diameter of the fixed rod 31. Simultaneously, as the third hydraulic rod 18 drives the mold platform 17 to rise and fall, the mold platform 17 drives the rotating column 28 to rise and fall synchronously. Through the second transmission groove 29 and the fixed rod 31, the rotating column 28 can be driven to rotate, thereby driving the turntable 24 to rotate. When the turntable 24 rotates, through the first transmission groove 26 and the slide rod 27, the clamping block 20 can be driven to move within the clamping block groove 19. Thus, through the rising and falling of the mold platform 17, the clamping blocks 20 can be driven to move synchronously closer or further apart. When the clamping blocks 20 move away from each other, the inclined clamping block groove 19 causes the clamping blocks 20 to gradually descend until the top of the clamping blocks 20 is below the top of the mold table 17, making the top of the mold table 17 flat. This avoids the protruding clamping blocks 20 causing obstruction when changing the mold. When it is necessary to squeeze the powder in the mold, the mold table 17 is raised, and the clamping blocks 20 move closer to each other simultaneously. At the same time, the clamping blocks 20 rise, which can clamp the four sides of the mold and position the mold, preventing the placed mold from shifting. The mold is automatically positioned when it rises, so that the powder in the mold can be vibrated and pressed later.

[0038] Working Principle: When using this vibratory pressing device for processing artificial quartz stone slabs, firstly, a feeding device and a receiving device are respectively set on both sides of the frame 1 corresponding to the processing groove 2. These are used to place the template on the mold table 17 or remove the template from the mold table 17. (Since the feeding device and receiving device are existing automated production equipment, and this solution is a vibratory pressing device, the existing technology is directly adopted, and the structure and working principle of the feeding device and receiving device are not explained in detail.) Through the two processing grooves 2 set on the frame 1, the mold tables 17 on both sides are alternately raised and lowered by the third hydraulic rod 18. After the template with powder is placed on the mold table 17, the third hydraulic rod 18 drives the template to move upward, so that the template moves to the processing groove 2. Inside, servo motor 10 drives lead screw 9 to rotate, causing lead screw 9 to move the traveling frame 6 directly above processing tank 2 via slider 8. First hydraulic rod 11 and second hydraulic rod 14 drive sealing cover 12 and pressure plate 15 to descend synchronously. After sealing processing tank 2 through sealing cover 12, the air extraction device creates a negative pressure state inside processing tank 2 through air extraction pipe 13, which can effectively remove air from the powder material laid in the template. Second hydraulic rod 14 continues to drive pressure plate 15 to move downward, compressing the powder material. With the cooperation of vibration motor 16, the powder material can be compressed and compacted. At the same time, another set of mold tables 17 moves downward, causing the template to be moved out of processing tank 2. The template on the other set of mold tables 17 is replaced by material picking and feeding equipment. With the lateral sliding of the vibratory pressing structure, the templates on the two sets of mold tables 17 are alternately vibrated and pressed. This allows for the processing of one set of artificial quartz stone slabs while the other set is being replaced, avoiding the vibratory press stopping during the replacement process. This effectively improves the continuity of the vibratory pressing device's operation and increases the processing efficiency of the artificial quartz stone slabs. Simultaneously, as the third hydraulic rod 18 raises and lowers the mold table 17, the mold table 17 drives the rotating column 28 to rise and fall synchronously. Through the second transmission groove 29 and the fixed rod 31, the rotating column 28 can be rotated, which in turn drives the turntable 24 to rotate. When the turntable 24 rotates, through the first transmission groove 26 and the sliding rod 27, the clamping block 20 can be clamped... The clamping blocks 20 move within the holding slot 19, and through the lifting and lowering of the mold table 17, the clamping blocks 20 move closer or further apart synchronously. When the clamping blocks 20 move further apart, the inclined clamping slot 19 causes the clamping blocks 20 to gradually descend until the top of the clamping blocks 20 is below the top of the mold table 17, making the top of the mold table 17 flat. This prevents the protruding clamping blocks 20 from obstructing the replacement of the mold. When it is necessary to squeeze the powder in the mold, the mold table 17 is raised, and the clamping blocks 20 move closer together synchronously. At the same time, the clamping blocks 20 rise, clamping the four sides of the mold and positioning the mold to prevent the placed mold from shifting. The mold is automatically positioned when it rises, so that the powder in the mold can be vibrated and pressed later.
