Description

Technical Field

[0001] This utility model belongs to the field of ceramic grouting technology, and specifically relates to a grouting device for ceramic production. Background Technology

[0002] In a broad sense, ceramics refers to solid materials made from inorganic non-metallic raw materials through molding and high-temperature firing. From everyday cups, bowls, and plates to high-precision components supporting modern industry, electronics, medical, and aerospace, ceramics, with their unique properties and infinite possibilities, continue to change and enrich human life.

[0003] Since ceramic slurry is a suspension, solid particles will gradually settle due to gravity when left to stand. Therefore, during the ceramic slurry casting process, the mold needs to be rotated to prevent particles in the slurry from accumulating downwards, which would result in a thick bottom and thin top of the green body, or even problems such as layering and uneven density.

[0004] In existing technology, the mold is usually placed on a workbench, the workbench is started to rotate the mold, and then the material gun is held above the mold's inlet to inject grout. However, when the mold is rotated, if the mold is not placed in the center of rotation, it is easy for it to shift or fall under the action of centrifugal force, thereby reducing its stability. Utility Model Content

[0005] To address the problem that when a mold is rotated, if it is not placed at the center of rotation, it is prone to shifting or falling under the action of centrifugal force, thereby reducing its stability, this utility model proposes a slurry injection device for ceramic production to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] The bottom end of the grouting assembly is fixedly installed to the top end of the transmission assembly so that the grouting assembly drives the transmission assembly to operate.

[0010] The top end of the reset component is fixedly connected to the bottom end of the transmission component, so that the reset component drives the transmission component to perform a reset movement;

[0011] The drive component has its output end fixedly installed at the bottom end of the support component, so that the drive component drives the support component to rotate;

[0012] The clamping assembly is fitted with the inner side of the transmission assembly on one side so that the transmission assembly drives the clamping assembly to clamp the mold when it is in operation.

[0013] Furthermore, the grouting assembly includes a support shaft, the bottom end of which is fixedly connected to the top end of the housing. An installation plate is fixedly mounted on the top end of the support shaft, and an electric push rod is fixedly mounted on the top end of the installation plate. A lifting frame is fixedly mounted on the telescopic end of the electric push rod. The interior of the lifting frame is slidably disposed with respect to the outer surface of the support shaft, and a grouting head is fixedly mounted inside the lifting frame.

[0014] Furthermore, the transmission assembly includes a push rod and a mounting bracket. The top end of the push rod is fixedly installed to the bottom end of the lifting frame, and the top end of the mounting bracket is fixedly installed to the inside of the housing. A first rack is slidably arranged inside the mounting bracket. A transmission gear is meshed with the surface of the first rack, and a second rack is meshed with the surface of the transmission gear.

[0015] A connecting plate is fixedly connected to one end of the second rack, and a support rod is fixedly connected to one side of the connecting plate. An arc-shaped frame is slidably provided on the outer surface of the support rod, and a first spring is fixedly connected to one side of the arc-shaped frame. One end of the first spring is fixedly connected to one side of the connecting plate.

[0016] Furthermore, the reset assembly includes a first fixing frame, the top end of the first fixing frame is fixedly connected to the bottom end of the mounting frame, a positioning rod is slidably arranged inside the first fixing frame, and a second fixing frame is fixedly connected to one end of the positioning rod;

[0017] The top end of the second fixing frame is fixedly connected to the bottom end of the second rack, and a return spring is fixedly connected to one side of the second fixing frame. One end of the return spring is fixedly connected to one side of the first fixing frame.

[0018] Furthermore, the drive assembly includes a connecting frame, the top of which is fixedly installed inside the housing, a motor is fixedly installed at the bottom of the connecting frame, and a drive shaft is fixedly installed at the output end of the motor.

[0019] Furthermore, the support assembly includes a support base, the bottom end of which is fixedly connected to the top end of the housing, and a support platform is rotatably mounted on the top end of the support base, the bottom end of which is fixedly installed to the top end of the drive shaft.

[0020] Furthermore, the clamping assembly includes a mounting groove, which is formed inside the support platform. A guide rod is fixedly connected inside the mounting groove, and a clamping plate is slidably disposed on the outer surface of the guide rod.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model places the mold on top of the support assembly, and then starts the grouting assembly to move downwards, causing it to drive the transmission assembly to operate. Since the inner side of the transmission assembly is in contact with one side of the clamping assembly, when the transmission assembly moves, it can push the clamping assembly to move, so that the clamping assembly clamps the mold along the inside of the support assembly. Since there are two sets of transmission assemblies, and the transmission ends of the two sets of transmission assemblies can be combined to form a circle, the drive assembly is started to drive the support assembly installed at the output end to rotate, so that the support assembly, together with the clamping assembly that is slidably set inside, drives the mold to rotate, so that one side of the clamping assembly rotates around the circle formed by the transmission assembly. Thus, the clamping assembly can still maintain the clamping state of the mold during the rotation, thereby improving the stability of the grouting process of the grouting equipment for ceramic production.

[0024] 2. This utility model uses two sets of arc-shaped frames combined into a circular frame, which can push the transmission ball that is attached to one side. When the transmission ball moves, it can drive the extension plate fixed on the outer surface to move, so that the extension plate drives the clamping plate fixed at the top to move. This causes the clamping plate to compress the second spring along the direction of the guide rod, and clamps and fixes the mold placed at the top of the support platform. When the support platform rotates, it can drive the mold to rotate in conjunction with the clamping plate. The clamping plate and the extension plate can also drive the transmission ball to rotate around the inner wall of the circular frame, thus ensuring that the clamping plate is always in a clamping state, thereby improving the stability of the mold during rotation.

[0025] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0036] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0037] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0038] Please see Figures 1-7As shown, this utility model is a slurry injection device for ceramic production, including a shell 1:

[0039] The housing 1 is respectively provided with a grouting assembly 2, a transmission assembly 3, a reset assembly 4, a drive assembly 5, a support assembly 6, and a clamping assembly 7;

[0040] The bottom end of the grouting component 2 is fixedly installed with the top end of the transmission component 3 so that the grouting component 2 drives the transmission component 3 to operate.

[0041] The top end of the reset component 4 is fixedly connected to the bottom end of the transmission component 3 so that the reset component 4 drives the transmission component 3 to perform a reset movement.

[0042] The drive component 5 is fixedly installed at its output end to the bottom end of the support component 6 so that the drive component 5 drives the support component 6 to rotate.

[0043] The clamping component 7 is fitted with the inner side of the transmission component 3 on one side so that the transmission component 3 drives the clamping component 7 to clamp the mold when it is in operation.

[0044] In use, the mold is placed on top of the support assembly 6, and then the grouting assembly 2 is activated to move downwards, causing the transmission assembly 3 to operate. Since the inner side of the transmission assembly 3 is in contact with one side of the clamping assembly 7, when the transmission assembly 3 moves, it can push the clamping assembly 7 to move, so that the clamping assembly 7 clamps the mold along the inside of the support assembly 6. At the same time, when the transmission assembly 3 moves, it can compress the reset assembly 4 fixed at the bottom. After the mold is clamped, the support assembly 6 installed at the output end is driven to rotate by activating the drive assembly 5, so that the support assembly 6, in conjunction with the clamping assembly 7 which is slidably set inside, drives the mold to rotate. Then, the grouting assembly 2 is activated again to grout into the mold.

[0045] This invention places the mold on top of the support assembly 6, then activates the grouting assembly 2 to move downwards, causing it to drive the transmission assembly 3. Since the inner side of the transmission assembly 3 is in contact with one side of the clamping assembly 7, when the transmission assembly 3 moves, it can push the clamping assembly 7 to move, so that the clamping assembly 7 clamps the mold along the inside of the support assembly 6. Since the transmission assembly 3 is provided in two sets, and the transmission ends of the two sets of transmission assemblies 3 can be combined to form a circle, the drive assembly 5 is activated to drive the support assembly 6 installed at the output end to rotate, so that the support assembly 6, in conjunction with the clamping assembly 7 which is slidably set inside, drives the mold to rotate, so that one side of the clamping assembly 7 rotates around the circle formed by the transmission assemblies 3. Thus, the clamping assembly 7 can still maintain the clamping state of the mold during the rotation, thereby improving the stability of the grouting process of the grouting equipment for ceramic production.

[0046] In one embodiment, the grouting assembly 2 includes a support shaft 201, the bottom end of which is fixedly connected to the top end of the housing 1. An mounting plate 202 is fixedly installed on the top end of the support shaft 201, and an electric push rod 203 is fixedly installed on the top end of the mounting plate 202. A lifting frame 204 is fixedly installed on the telescopic end of the electric push rod 203. The interior of the lifting frame 204 is slidably disposed with respect to the outer surface of the support shaft 201, and a grouting head 205 is fixedly installed inside the lifting frame 204.

[0047] The lifting frame 204 installed on the telescopic end is moved by activating the electric push rod 203. Since the inside of the lifting frame 204 is slidably set with the outer surface of the support shaft 201, and the inside of the lifting frame 204 is fixedly installed with the outer surface of the grouting head 205, when the lifting frame 204 moves, it can drive the grouting head 205 to move up and down along the direction of the support shaft 201, so as to adjust the height of the grouting head 205, thereby facilitating the loading and unloading of the mold below the grouting head 205.

[0048] In one embodiment, the transmission assembly 3 includes a push rod 301 and a mounting bracket 302. The top end of the push rod 301 is fixedly installed with the bottom end of the lifting frame 204, and the top end of the mounting bracket 302 is fixedly installed with the inside of the housing 1. A first rack 303 is slidably arranged inside the mounting bracket 302. A transmission gear 304 is meshed with the surface of the first rack 303, and a second rack 305 is meshed with the surface of the transmission gear 304.

[0049] One end of the second rack 305 is fixedly connected to a connecting plate 306, and a support rod 307 is fixedly connected to one side of the connecting plate 306. An arc-shaped frame 308 is slidably provided on the outer surface of the support rod 307, and a first spring 309 is fixedly connected to one side of the arc-shaped frame 308. One end of the first spring 309 is fixedly connected to one side of the connecting plate 306.

[0050] When the lifting frame 204 moves, it can drive the top rod 301 mounted at its bottom to move as well. Since the bottom end of the top rod 301 corresponds to the top end of the first rack 303, when the top rod 301 moves, it can contact the top end of the first rack 303 during its movement, pushing the first rack 303 to move. This, in turn, causes the first rack 303 to drive the surface-meshing transmission gear 304 to rotate, thereby causing the transmission gear 304 to drive the surface-meshing second rack 305 to move. Because the first rack 303 and the second rack 305 are at an angle... The vertical arrangement allows the second rack 305 to move horizontally, driving the connecting plate 306 fixed at one end to move. This, in turn, causes the connecting plate 306 to move the support rod 307 fixed on one side. The support rod 307 then moves the arc-shaped frame 308, which is slidably mounted on its outer surface. The arc-shaped frame 308 moves in conjunction with the compressive stress of the first spring 309 fixed on one side, and the first spring 309 buffers the movement of the arc-shaped frame 308, thereby improving the fault tolerance rate during the operation of the grouting equipment for ceramic production.

[0051] In one embodiment, the reset component 4 includes a first fixing frame 401, the top end of the first fixing frame 401 is fixedly connected to the bottom end of the mounting frame 302, a positioning rod 402 is slidably disposed inside the first fixing frame 401, and a second fixing frame 403 is fixedly connected to one end of the positioning rod 402.

[0052] The top end of the second fixing bracket 403 is fixedly connected to the bottom end of the second rack 305. A return spring 404 is fixedly connected to one side of the second fixing bracket 403, and one end of the return spring 404 is fixedly connected to one side of the first fixing bracket 401.

[0053] When the second rack 305 moves with the rotation of the transmission gear 304, it can drive the second fixed frame 403 fixed at the bottom to move, so that the second fixed frame 403 drives the positioning rod 402 fixed on one side to move, thereby causing the positioning rod 402 to move along the inside of the first fixed frame 401, and causing the second fixed frame 403 to compress the return spring 404 fixed on one side. Then, when the second rack 305 loses its driving force, the return spring 404 can release the compressive stress and cooperate with the second fixed frame 403 to drive the second rack 305 to reset, which is more convenient.

[0054] In one embodiment, the drive assembly 5 includes a connecting frame 501, the top end of which is fixedly installed inside the housing 1, a motor 502 is fixedly installed at the bottom end of the connecting frame 501, and a drive shaft 503 is fixedly installed at the output end of the motor 502.

[0055] The drive shaft 503 installed at the output end of the motor 502 is driven to rotate by the start motor 502, and the connecting bracket 501 can support the motor 502 installed at the bottom, thereby improving the stability of the motor 502 during operation.

[0056] In one embodiment, the support component 6 includes a support base 601, the bottom end of which is fixedly connected to the top end of the housing 1, and a support platform 602 is rotatably provided on the top end of the support base 601, the bottom end of which is fixedly installed to the top end of the drive shaft 503.

[0057] The drive shaft 503 installed at the output end of the motor 502 is driven to rotate, so that the drive shaft 503 drives the support platform 602 installed at the top to rotate. Since the bottom end of the support platform 602 is rotated with the top end of the support base 601, the position of the support platform 602 can be restricted, thereby improving the stability of the support platform 602 during operation.

[0058] In one embodiment, the clamping assembly 7 includes a mounting groove 701, which is formed inside the support platform 602. A guide rod 702 is fixedly connected inside the mounting groove 701. A clamping plate 703 is slidably disposed on the outer surface of the guide rod 702. A second spring 704 is fixedly connected to one side of the clamping plate 703. One end of the second spring 704 is fixedly connected to the inside of the mounting groove 701.

[0059] An extension plate 705 is fixedly connected to the bottom end of the clamping plate 703, and a transmission ball 706 is fixedly connected to the bottom end of the extension plate 705. The outer surface of the transmission ball 706 is in contact with the inner side of the arc frame 308.

[0060] Since there are two sets of arc-shaped frames 308 arranged symmetrically, when the two sets of arc-shaped frames 308 move, they can be combined into a circular frame, which can then push the transmission ball 706 attached to one side. When the transmission ball 706 moves, it can drive the extension plate 705 fixed on the outer surface to move, so that the extension plate 705 drives the clamping plate 703 fixed at the top to move. This causes the clamping plate 703 to compress the second spring 704 along the direction of the guide rod 702, and clamps and fixes the mold placed at the top of the support platform 602. When the support platform 602 rotates, it can work with the clamping plate 703 to drive the mold to rotate, and the clamping plate 703, together with the extension plate 705, can drive the transmission ball 706 to rotate around the inner wall of the circular frame, thus ensuring that the clamping plate 703 is always in a clamping state, thereby improving the stability of the mold during rotation.

[0061] Through the above technical solution, 1. By placing the mold on the top of the support component 6, and then starting the grouting component 2 to move downward, so as to drive the transmission component 3 to operate. Since the inner side of the transmission component 3 is in contact with one side of the clamping component 7, when the transmission component 3 moves, it can push the clamping component 7 to move, so that the clamping component 7 clamps the mold along the inside of the support component 6. Since the transmission component 3 is provided with two sets, and the transmission ends of the two sets of transmission components 3 can be combined into a circle, the support component 6 installed at the output end is driven to rotate by starting the drive component 5, so that the support component 6 cooperates with the clamping component 7 that is slidably set inside to drive the mold to rotate, so that one side of the clamping component 7 rotates around the circle formed by the transmission components 3, so that the clamping component 7 can still maintain the clamping state of the mold during the rotation, thereby improving the stability of the grouting process of the grouting equipment for ceramic production.

[0062] 2. A circular frame is formed by combining two sets of arc-shaped frames 308, which can push the transmission ball 706 that is attached to one side. When the transmission ball 706 moves, it can drive the extension plate 705 fixed on the outer surface to move, so that the extension plate 705 drives the clamping plate 703 fixed at the top to move. This causes the clamping plate 703 to compress the second spring 704 along the direction of the guide rod 702, and clamps and fixes the mold placed at the top of the support platform 602. When the support platform 602 rotates, it can drive the mold to rotate in conjunction with the clamping plate 703. The clamping plate 703 and the extension plate 705 can drive the transmission ball 706 to rotate around the inner wall of the circular frame, thus ensuring that the clamping plate 703 is always in a clamping state, thereby improving the stability of the mold during rotation.
