Description

Technical Field

[0001] This utility model relates to the field of ceramic production technology, and more specifically, to a continuous slurry injection mechanism for ceramic production. Background Technology

[0002] The slurry casting process in ceramic production involves injecting prepared slurry into a mold. In some small workshops, when using slurry casting to produce ceramics, the mold is usually assembled first, then the slurry is injected into the mold. After the area in contact with the slurry inside the mold hardens, the mold is flipped over to pour out the excess slurry. Small workshops usually use manual pouring of slurry, which has low continuity. At the same time, the injection rate cannot be adjusted, which easily leads to slurry splashing or overflow, and slurry clumping can also cause discharge blockage. Therefore, it is necessary to propose a continuous slurry casting mechanism for ceramic production. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model provides a continuous grouting mechanism for ceramic production.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A continuous slurry injection mechanism for ceramic production includes: a clay hopper, an injection pipe and a conveying frame, wherein the injection pipe is connected to the clay hopper through a discharge pipe, and an electrically controlled valve is installed on the surface of the discharge pipe to control the discharge time and realize the conveying of clay. The conveyor frame is securely connected to the mud hopper using a support frame. In addition, the device is equipped with an extrusion disc, which can be flexibly lifted and rotated inside the injection tube.

[0005] In the aforementioned continuous slurry injection mechanism for ceramic production, the inside of the mud hopper is equipped with a flexibly rotating stirring rod. In addition, the device is equipped with a stirring motor, which is securely mounted on the surface of the mud hopper. Its output end is tightly fixed to the stirring rod. Driven by the motor, it can efficiently drive the stirring rod to fully stir the mud in the mud hopper.

[0006] In the aforementioned continuous grouting mechanism for ceramic production, two retaining rings are fixedly connected inside the grouting pipe, and the retaining rings have a movable ring that can rotate flexibly inside. A guide rod is fixedly connected between the two movable rings to provide stable support for the overall structure. The extrusion disc can be sleeved on the surface of the guide rod. While it is lifting and rotating inside the injection tube, it is constrained by the guide rod to ensure that the running trajectory is accurate and controllable.

[0007] In the aforementioned continuous grouting mechanism for ceramic production, the top of the grouting pipe is equipped with a flexibly rotatable turntable, and a toothed ring is fixedly connected to the surface of the turntable for transmitting rotational power. The turntable has an internal through-hole to provide space and guidance for the movement of other components, ensuring smooth operation of all components.

[0008] In the aforementioned continuous grouting mechanism for ceramic production, a lifting connecting rod is vertically fixedly connected to the top of the extrusion disc, and the lifting mounting plate is rotatably connected to the lifting connecting rod through a precision bearing to ensure smooth and stable rotation during the lifting process. The bottom of the extrusion plate is firmly fixed with a conical mixing frame, which can perform multi-angle and efficient mixing of the mud in the injection pipe when the extrusion plate is raised, lowered and rotated, so as to avoid the mud from accumulating or clumping.

[0009] In the aforementioned continuous grouting mechanism for ceramic production, a lifting bracket is securely fixed to the top of the grouting pipe. The lifting bracket has a flexibly rotatable lifting threaded rod inside, which is tightly engaged with the lifting mounting plate through threads to form a precise transmission connection. A lifting motor is installed on the top of the lifting bracket. The output end of the motor is directly connected to the lifting threaded rod. The motor drives the threaded rod to rotate, which transmits power precisely, thereby driving the lifting mounting plate to rise and fall smoothly along the threaded rod, realizing the height adjustment of the components below.

[0010] In the aforementioned continuous slurry injection mechanism for ceramic production, a motor bracket is securely fixed to the side of the injection pipe, providing stable support for power transmission. A rotary motor is mounted on top of the motor bracket, serving as the core power source for the drive device. The output end of the rotary motor is connected to a conversion gear, which precisely meshes with a gear ring on the surface of the turntable. Through the operation of the rotary motor, power is efficiently transmitted to the gear ring via the conversion gear, thereby driving the turntable to achieve stable rotation.

[0011] The aforementioned continuous grouting mechanism for ceramic production, wherein a one-way valve is fixedly connected to the bottom of the grouting pipe, further includes: Grouting mold, which is mounted on top of the conveyor frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model realizes a continuous slurry injection mechanism for ceramic production through the cooperation of a mud hopper, a slurry injection pipe, a conveying frame, a support frame, and an extrusion plate. After the mud falls into the slurry injection pipe through the mud hopper, the lifting motor drives the lifting threaded rod to rotate, which in turn drives the lifting bracket connected to the threaded rod to move up and down. Under the pushing action of the lifting connecting rod, the extrusion plate descends accordingly, and the mud in the slurry injection pipe is evenly squeezed out through the one-way valve. By adjusting the speed of the lifting motor, the slurry injection rate can be flexibly adjusted according to the actual use requirements, effectively avoiding mud splashing or overflow.

[0013] 2. In this utility model, after the rotary motor is started, the turntable begins to rotate under the transmission action of the conversion gear, which drives the extrusion plate to rotate synchronously during the descent, stirring the mud in the injection pipe and effectively preventing the mud from clumping.

[0014] 3. In this utility model, the stirring motor drives the stirring rod to rotate, stirring the mud inside the mud hopper to prevent the mud inside the mud hopper from settling.

[0015] 4. In this utility model, the guide rod can guide the lifting direction of the extrusion disc, ensuring the stability of the extrusion disc's movement. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-4 As shown, a continuous slurry injection mechanism for ceramic production mainly consists of three core components: a slurry hopper 1, an injection pipe 2, and a conveyor frame 3. The injection pipe 2 is connected to the slurry hopper 1 via a discharge pipe. An electrically controlled valve is installed on the surface of the discharge pipe to control the discharge time, forming a slurry conveying channel. The conveyor frame 3 is rigidly connected to the slurry hopper 1 via a support frame 4 to ensure overall structural stability. The device includes an extrusion disc 5 that can perform a combined lifting and rotating motion within the injection pipe 2 for precise control of slurry delivery and processing.

[0020] The mud hopper 1 is equipped with a stirring rod 6 that can rotate freely 360°. It is driven by a stirring motor 7 installed on the top of the mud hopper 1. The stirring motor 7 adopts a direct-drive design, and its output shaft is rigidly fixed to the stirring rod 6. The high-speed rotation of the motor drives the stirring rod 6 to fully stir the mud, effectively preventing mud sedimentation and stratification.

[0021] The injection tube 2 has a double-layer positioning structure, consisting of two fixed retaining rings 8 and a movable ring 9 nested within them. The two movable rings 9 are rigidly connected by a guide rod 10, providing a precise movement track for the extrusion disc 5. The extrusion disc 5 can slide axially and rotate circumferentially along the guide rod 10, ensuring that its movement trajectory within the injection tube 2 is stable and controllable.

[0022] The top of the injection pipe 2 is equipped with a transmission turntable 11. The surface of the turntable is integrated with a toothed ring 12 for power transmission. The interior is provided with a movable through hole 13 to reserve space for the movement of other components. The extrusion plate 5 is connected to the lifting mounting plate 15 through a vertically installed lifting connecting rod 14. The two are connected by precision bearings to ensure smooth lifting. The conical stirring frame 16 fixed at the bottom of the extrusion plate 5 can perform spiral stirring of the mud when the extrusion plate 5 moves, further improving the uniformity of the mud.

[0023] The lifting bracket 17 at the top of the injection tube 2 has a built-in lifting threaded rod 18, which forms a precision threaded transmission pair with the lifting mounting plate 15. The lifting motor 19 is installed at the top of the bracket and drives the threaded rod 18 to rotate through a direct connection, thereby achieving precise displacement control of the lifting mounting plate 15 and adjusting the working height of the extrusion plate 5.

[0024] The side of the injection pipe 2 is equipped with a motor bracket 20, on which a rotary motor 21 is installed as a power source. The motor's rotational power is efficiently transmitted to the turntable 11 through the meshing of the gear ring 12 of the turntable 11 via the conversion gear 22, driving it to operate stably. The one-way valve 23 installed at the bottom of the injection pipe 2 can effectively prevent the slurry from flowing back and ensure the one-way flowability of the grouting process.

[0025] The grouting mold 24, as the terminal execution component of the device, is fixedly installed on the top of the conveyor frame 3 and precisely aligned with the outlet of the grouting pipe 2 to ensure that the slurry can be accurately injected into the mold cavity.

[0026] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0027] This utility model provides a continuous grouting mechanism for ceramic production. In use, clay enters the grouting pipe 2 through the clay hopper 1. The rotary motor 21 and the lifting motor 19 are started. The lifting motor 19 drives the lifting threaded rod 18 to rotate, which drives the lifting bracket 17 connected to it to move up and down. Under the push of the lifting connecting rod 14, the extrusion plate 5 descends synchronously, squeezing the clay in the grouting pipe 2 evenly through the one-way valve 23. By adjusting the speed of the lifting motor 19, the grouting rate can be flexibly adjusted according to actual needs. At the same time, under the transmission action of the conversion gear 22, the turntable 11 drives the extrusion plate 5 to rotate synchronously during the descent, continuously stirring the clay in the grouting pipe 2, effectively preventing the clay from clumping. After grouting is completed, the lifting motor 19 reverses and drives the extrusion plate 5 back to the top of the inner wall of the grouting pipe 2. The conveyor frame 3 drives the grouting mold 24 to complete automatic feeding, ensuring the continuity of grouting.

[0028] In summary, the continuous slurry injection mechanism for ceramic production, through the cooperation of the mud hopper 1, the injection pipe 2, the conveyor frame 3, the support frame 4, and the extrusion plate 5, solves the problems mentioned in the background art.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
