Description

Technical Field

[0001] This invention relates to the field of ceramic forming, and more specifically, to a ceramic forming machine. Background Technology

[0002] Dry pressing of ceramics is a commonly used ceramic forming technology. Typically, dry pressing of ceramics involves loading granulated powder into a metal mold, applying pressure through a press head, causing the powder particles to come close together inside the mold and firmly bond together through internal friction, forming a ceramic blank with a certain shape and strength, such as ceramic slabs.

[0003] Existing ceramic forming machines often add ceramic powder too quickly, causing the powder to accumulate too rapidly. This prevents air from escaping, trapping it within the powder layer. Under pressure, this results in internal voids and dark cracks, leading to bulging, delamination, and inconsistent density after sintering. Consequently, the ceramic slabs are scrapped, increasing production costs. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a ceramic forming machine.

[0005] To solve the above problems, the present invention adopts the following technical solution.

The initial preload of the first spring is greater than the total weight of the motor base, the drive motor and the cam.

[0009] Furthermore, a support groove is provided on one side of the slot, and a support block is provided on one side of the back of the molding die, and the support block slides inside the support groove.

[0010] Furthermore, the demolding assembly includes an air pump fixed to one side of the inner surface of the U-shaped frame, air outlet slots opened on the front and rear sides of the top of the top plate, and a rectangular frame fixed on the front and rear sides of the top of the guide cavity. Multiple air jet holes are opened on both sides of the rectangular frame. A servo motor is fixedly connected to the front and rear sides of the bottom of the guide cavity. A threaded rod is fixedly connected to the output end of the servo motor. An internal threaded cylinder is sleeved on the outer surface of the threaded rod. A sealing plate is fixedly connected to the top of the internal threaded cylinder. A first air inlet hose is fixedly connected to the output end of the air pump.

[0011] Furthermore, the sealing plate is adapted to the air outlet groove, the sealing plate is slidably adapted to the inside of the rectangular frame, one end of the first air intake hose is connected to the bottom of the top plate, and the first air intake hose is in communication with the inside of the guide cavity.

[0012] Furthermore, a dust collection assembly is provided on both sides of the top of the base. The dust collection assembly includes an air inlet pipe fixed on both sides of the top of the base and a second air inlet hose fixed on the output end of the air pump. A rectangular dust collection frame is fixedly connected to the side of the two air inlet pipes that are close to each other. Suction holes are evenly opened on the inner side of the rectangular dust collection frame. An internal threaded sleeve is fixedly connected to one end of the air inlet pipe and one end of the second air inlet hose. A dust filter is connected to the internal threads of the two internal threaded sleeves.

[0013] Furthermore, the rectangular dust collection frame is located at the upper edge of the two forming molds, and the interior of the rectangular dust collection frame is interconnected with the interior of the dust filter. The outer surface of the dust filter is provided with threads, and the inner threaded sleeve and the dust filter are connected by threads.

[0014] Furthermore, a pusher assembly is provided at the corners on both sides of the top of the base. The pusher assembly includes a fourth hydraulic rod fixed at the corner of the top of the base. The output end of the fourth hydraulic rod is fixedly connected to a transmission plate, and one end of the transmission plate is fixedly connected to a pusher plate.

[0015] Furthermore, a conveyor belt assembly is fixedly connected to the front side of the base, an opening is provided on the rear side of the top of the forming mold, a discharge groove is provided on the front side of the forming mold, a roller groove is provided at the bottom of the discharge groove, and a roller is rotatably connected inside the roller groove.

[0016] Furthermore, the opening and the pusher plate are adapted to each other, the upper surface of the conveyor belt assembly is flush with the upper surface of the roller, the air pump delivers airflow to the guide cavity, the airflow is ejected through the air outlet groove, and forms an air cushion structure on the top of the top plate. When the pusher plate moves inside the opening and pushes the ceramic plate toward the conveyor belt assembly, the air cushion structure is used to reduce the friction between the ceramic plate and the surface of the top plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. This solution incorporates a shaking component, which causes the top plate to move up and down continuously inside the two molding dies. This shaking action not only removes air bubbles from the powder but also forces the powder to distribute evenly, ensuring consistent density across all parts of the formed powder. This improves the density of the formed ceramic slab and enhances its quality.

[0019] 2. This solution incorporates a demolding assembly. An air pump delivers airflow into the guide cavity via a first air inlet hose. The airflow is then sprayed through jet holes onto the bottom of the ceramic plate, separating the ceramic plate from the top of the top plate. This prevents adhesion and cracking, ensuring smooth demolding of the ceramic plate. Not only does it utilize airflow for demolding separation, but it also cleverly uses residual airflow to form a micro-air cushion on the surface of the top plate during the subsequent pushing process. This significantly reduces the bottom friction when the pusher plate pushes the ceramic plate sideways, effectively preventing scratches and cracks on the bottom surface of the green blank during the translational pushing process. This achieves a high degree of coordination in streamlined operations.

[0020] 3. This solution incorporates a dust collection component. The air pump, through the cooperation of the second air intake hose and the air intake pipe, creates negative pressure in the rectangular dust collection frame, drawing air in through the suction holes. When dust flies out from inside the molding die, it is absorbed by the strong suction around the suction holes and transported through the air intake pipe to the dust filter for collection. This prevents dust from spreading and causing environmental pollution. The rotating dust filter, under the action of the threads, moves out from inside the two internal threaded sleeves for easy replacement. Attached Figure Description

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1 to 7 A ceramic molding machine includes a base 1 with a slot 7 inside. A first hydraulic rod 2 is fixedly connected to both sides of the top of the base 1. A molding mold 6 is fixedly connected to the output end of the first hydraulic rod 2. A support base 3 is fixedly connected to one end of the back of the top of the base 1. A second hydraulic rod 4 is fixedly connected to the bottom of the support base 3. An upper pressure head 5 is fixedly connected to the output end of the second hydraulic rod 4. A vibration component 8 for demolding is provided on both sides of the bottom of the base 1.

[0037] like Figures 3-5 As shown, the vibration component 8 includes a U-shaped frame 81 fixed to the bottom of the base 1 and a buffer groove 87 opened at one end of the back of the bottom of the base 1. A first spring 88 is fixedly connected to the bottom of the buffer groove 87. A motor base 82 is fixedly connected to the bottom of the first spring 88. A drive motor 83 is fixedly connected to one side of the motor base 82. A transmission shaft 89 is fixedly connected to the output end of the drive motor 83. A cam 810 is fixedly connected to one side of the transmission shaft 89. A third hydraulic rod 84 is fixedly connected to both sides of the top of the U-shaped frame 81. A sleeve 812 is sleeved on the outer surface of the output end of the third hydraulic rod 84. A second spring 813 is fixedly connected to the output end of the third hydraulic rod 84. A top plate 10 is fixedly connected to the top of the sleeve 812. A flow guide cavity 11 is opened inside the base 1. An extrusion rod 811 is fixedly connected to the outer surface of the two sleeves 812. A demolding component 85 is provided at the base 1 and the U-shaped frame 81.

[0038] Cam 810 is located above extrusion rod 811, motor base 82 is L-shaped, second spring 813 is located inside sleeve 812, there are two forming molds 6, top plate 10 is located between the two forming molds 6, top plate 10 is adapted to the cavity formed by the two forming molds 6, sliders are fixedly installed on the two side walls of motor base 82, and linear guide rails that slide with the sliders are opened on the inner side wall of buffer groove 87. The initial preload of first spring 88 is greater than the total weight of motor base 82, drive motor 83 and cam 810.

[0039] A support groove is provided on one side inside the slot 7, and a support block is provided on one side of the back of the forming mold 6, and the support block slides inside the support groove.

[0040] During the dry pressing of ceramic plates, when ceramic powder is fed into the cavity formed by the two forming molds 6 and the top plate 10, the powder is unevenly distributed and contains air bubbles. Therefore, after adding powder, the drive motor 83 is started, which drives the cam 810 to rotate via the transmission shaft 89. The rotation of the cam 810 causes its distal point to contact the extrusion rod 811, thus pushing the extrusion rod 811 downwards. This, in turn, causes the top plate 10 to move downwards via the two sleeves 812. The top plate 10 then acts as a second spring inside the sleeves 812. Spring 813 performs extrusion. When the distal point of cam 810 moves away from extrusion rod 811, under the elastic force of the two second springs 813, it drives the top plate 10 to move upward and reset. Cam 810 rotates continuously, causing the top plate 10 to move up and down continuously inside the two forming molds 6. This can cause the powder on the top of the top plate 10 to shake, which can not only remove air bubbles inside the powder, but also force the powder to be evenly distributed, ensuring that the density of each part is consistent after the powder is formed, improving the density of the ceramic plate and improving the quality.

[0041] After the upper pressure head 5 dry-presses the powder, the second hydraulic rod 4 slowly releases pressure and smoothly moves away from the inside of the forming mold 6. The first hydraulic rod 2 is activated to drive the forming mold 6 to move inside the slot 7, so that the two forming molds 6 are separated from the ceramic plate. Then the third hydraulic rod 84 is activated to slowly push the top plate 10 upward. The top plate 10 slowly moves the formed ceramic plate upward. During the upward movement, the sleeve 812 moves upward synchronously. The extrusion rod 811 pushes the cam 810 upward, which synchronously drives the drive motor 83 and the motor seat 82 to move upward. The motor seat 82 moves upward inside the buffer groove 87 and compresses the first spring 88 to ensure that the cam 810 does not interfere with the movement of the extrusion rod 811. The initial preload of the first spring 88 is greater than the total weight of the motor seat 82, the drive motor 83 and the cam 810 to ensure that the cam 810 can stably maintain on the working reference plane to apply a downward thrust to the extrusion rod 811 during the normal forming process.

[0042] like Figures 5-7 As shown, the demolding assembly 85 includes an air pump 851 fixed to one side of the inner surface of the U-shaped frame 81, an air outlet groove 856 opened on the front and rear sides of the top of the top plate 10, and a rectangular frame 854 fixed on the front and rear sides of the top of the guide cavity 11. Multiple air jet holes 855 are opened on both sides of the rectangular frame 854. A servo motor 857 is fixedly connected to the front and rear sides of the bottom of the guide cavity 11. A threaded rod 859 is fixedly connected to the output end of the servo motor 857. An internal threaded cylinder 858 is sleeved on the outer surface of the threaded rod 859. A sealing plate 853 is fixedly connected to the top of the internal threaded cylinder 858. A first air inlet hose 852 is fixedly connected to the output end of the air pump 851.

[0043] The sealing plate 853 and the air outlet groove 856 are adapted to each other, the sealing plate 853 and the inside of the rectangular frame 854 are slidably adapted to each other, one end of the first air inlet hose 852 is connected to the bottom of the top plate 10, and the first air inlet hose 852 is connected to the inside of the guide cavity 11.

[0044] After molding is completed, the servo motor 857 is started to drive the threaded rod 859 to rotate. The threaded rod 859 drives the sealing plate 853 to move into the rectangular frame 854 through the inner threaded cylinder 858 until the sealing plate 853 moves below the air jet hole 855, so that the inside of the guide cavity 11 is connected to the inside of the molding mold 6 through the air jet hole 855. Then, the air pump 851 is started to deliver airflow into the guide cavity 11 through the first air inlet hose 852. The airflow is sprayed into the bottom of the ceramic plate through the air jet hole 855, so that the ceramic plate separates from the top of the top plate 10, avoiding cracking caused by adhesion and ensuring that the ceramic plate is demolded smoothly.

[0045] like Figure 5 As shown, a dust collection assembly 86 is provided on both sides of the top of the base 1. The dust collection assembly 86 includes an air inlet pipe 864 fixed on both sides of the top of the base 1 and a second air inlet hose 861 fixed on the output end of the air pump 851. A rectangular dust collection frame 865 is fixedly connected to one side of the two air inlet pipes 864 that are close to each other. Suction holes 866 are evenly opened on the inner side of the rectangular dust collection frame 865. An internal threaded sleeve 863 is fixedly connected to one end of the air inlet pipe 864 and one end of the second air inlet hose 861. A dust filter 862 is connected to the internal threads of the two internal threaded sleeves 863.

[0046] The rectangular dust collection frame 865 is located at the upper edge of the two forming molds 6. The interior of the rectangular dust collection frame 865 is connected to the interior of the dust filter 862. The outer surface of the dust filter 862 is provided with threads, and the inner threaded sleeve 863 and the dust filter 862 are connected by threads.

[0047] During the demolding process, the airflow inside the guide cavity 11 is ejected through the jet hole 855. The airflow separates the ceramic plate from the molding mold 6 and the top plate 10. However, during jetting, the powder adhering to the inner wall of the molding mold 6 is also blown into the air, causing dust to fly everywhere. Therefore, when the air pump 851 jets into the guide cavity 11, the air pump 851, through the cooperation of the second air inlet hose 861 and the air inlet pipe 864, creates a negative pressure in the rectangular dust collection frame 865, which draws air in through the suction hole 866. When dust flies out from the inside of the molding mold 6, it is absorbed by the strong suction around the suction hole 866 and transported to the inside of the dust filter 862 through the air inlet pipe 864 for collection. This can prevent the spread of dust and environmental pollution. The rotating dust filter 862 is moved out from inside the two internal threaded sleeves 863 by the action of the threads for easy replacement.

[0048] like Figure 2 , Figure 4 and Figure 5 As shown, a pusher assembly 9 is provided at the corners of the top two sides of the base 1. The pusher assembly 9 includes a fourth hydraulic rod 91 fixed at the corner of the top of the base 1. The output end of the fourth hydraulic rod 91 is fixedly connected to a transmission plate 92. One end of the transmission plate 92 is fixedly connected to a pusher plate 93.

[0049] A conveyor belt assembly 95 is fixedly connected to the front side of the base 1. An opening 94 is opened on the rear side of the top of the forming mold 6. A discharge groove 96 is opened on the front side of the forming mold 6. A roller groove is opened at the bottom of the discharge groove 96, and a roller is rotatably connected inside the roller groove.

[0050] The opening 94 and the pusher plate 93 are adapted to each other. The upper surface of the conveyor belt assembly 95 is flush with the upper surface of the roller. The air pump 851 delivers airflow to the guide cavity 11. The airflow is ejected through the air outlet 856 and forms an air cushion structure on the top of the top plate 10. When the pusher plate 93 moves inside the opening 94 and pushes the ceramic plate toward the conveyor belt assembly 95, the air cushion structure is used to reduce the friction between the ceramic plate and the surface of the top plate 10.

[0051] After the ceramic plate is formed, the top plate 10 pushes the ceramic plate upward so that the top of the top plate 10 is flush with the bottom of the opening 94. At this time, the fourth hydraulic rod 91 is activated to drive the pusher plate 93 to move into the opening 94 through the transmission plate 92. The pusher plate 93 pushes the ceramic plate on the top of the top plate 10 to move towards the conveyor belt assembly 95. With the airflow sprayed from the air outlet 856, the friction between the ceramic plate and the surface of the top plate 10 is reduced. The ceramic plate moves along the roller to the top of the conveyor belt assembly 95 and is transferred to the next process, realizing streamlined operation, reducing the step of manual blank removal, and avoiding damage to the ceramic plate by external force.

[0052] Instructions for use: The ceramic powder is fed into the cavity formed by the two molding dies 6 and the top plate 10. The drive motor 83 is started, and the cam 810 is rotated through the transmission shaft 89, causing the extrusion rod 811 to move up and down continuously. Through transmission, the top plate 10 moves up and down continuously inside the two molding dies 6, which can cause the powder on the top of the top plate 10 to shake / vibrate. This can not only remove air bubbles inside the powder, but also start the second hydraulic rod 4 to drive the upper pressure head 5 to move into the molding die 6 to press the dry powder into shape.

[0053] After molding is completed, the servo motor 857 is started to drive the threaded rod 859 to rotate. The threaded rod 859 drives the sealing plate 853 to move into the rectangular frame 854 through the inner threaded cylinder 858 until the sealing plate 853 moves below the air jet hole 855, so that the inside of the guide cavity 11 is connected to the inside of the molding mold 6 through the air jet hole 855. Then the air pump 851 is started to deliver airflow into the guide cavity 11 through the first air inlet hose 852. The airflow is sprayed into the bottom of the ceramic plate through the air jet hole 855, so that the ceramic plate separates from the top of the top plate 10, avoiding cracking caused by adhesion and ensuring that the ceramic plate is demolded smoothly.

[0054] The air pump 851, through the cooperation of the second air intake hose 861 and the air intake pipe 864, creates a negative pressure in the rectangular dust collection frame 865, drawing air in through the air intake hole 866. When dust flies out from inside the molding die 6, it is absorbed by the strong suction around the air intake hole 866 and transported through the air intake pipe 864 to the inside of the dust filter 862 for collection, thereby preventing the spread of dust and pollution to the environment.

[0055] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
