Description

Technical Field

[0001] This utility model belongs to the field of clay processing technology, and in particular relates to a continuous three-in-one molding machine for honeycomb ceramics. Background Technology

[0002] The continuous three-in-one molding machine for honeycomb ceramics is an automated molding equipment that integrates multiple process steps such as material storage, mixing / stirring, crushing, degassing and extrusion molding into one machine. It completes the processes that originally required multiple independent machines in a continuous production process in the same machine, thereby improving production efficiency and product consistency.

[0003] However, some problems still exist in the above solutions: 1. Existing clay extrusion molding equipment generally adopts a horizontal extrusion structure. During the clay pushing process, the clay is prone to displacement due to the superposition of its own weight and horizontal conveying force, resulting in insufficient dimensional stability and molding uniformity of the extruded products. In addition, most traditional equipment relies on simple hopper storage in the material storage stage, lacking effective stirring and moisturizing functions. During the static process, the clay is prone to uneven drying and wetting, local agglomeration or hardening, which affects the continuity of screw feeding and vacuum degassing effect. At the same time, the traditional screw feeding structure cannot achieve precise control of clay flow rate, resulting in unstable instantaneous feeding, making it difficult to maintain stable pressure in the subsequent extrusion stage and affecting product consistency.

[0004] 2. Before the clay enters the extrusion section, many existing equipment lacks effective impurity filtration or homogenization structures. Hard particles, metal fragments, or unmixed hard clay lumps in the clay can easily enter the mold, leading to increased mold wear, more product surface defects, and even extrusion blockage. In addition, most equipment uses a straight-through extrusion path, which cannot be structurally adjusted in the extrusion direction, thus restricting the forming direction and making it difficult to meet the production requirements of vertical extrusion products. The front section of the mold in existing equipment usually does not have a resistance tube or its structure is unreasonable, making it impossible to form a stable extrusion pressure zone. This results in insufficient density of the extruded product and easy deformation after forming, making it difficult to meet the manufacturing requirements of high-precision clay products. Utility Model Content

[0005] This utility model provides a continuous three-in-one molding machine for honeycomb ceramics, which aims to solve the problems mentioned in the background art.

[0006] This utility model is implemented as follows: a continuous three-in-one molding machine for honeycomb ceramics includes: a platform, a hydraulic feeder, a storage bin, a transmission rod, a resistance tube, a screen changer, a flange, a hydraulic cylinder, a right-angle breaking mechanism, a discharge port, a screw, a vacuum chamber, a motor, a transmission wheel, a transmission belt, a stirring blade, a vertical extruder unit, and a mold. The motor drives one of the drive wheels to rotate, and the drive wheel drives the other drive wheel and drive rod to rotate via a drive belt. The drive rod drives the stirring blade to stir and mix the material inside the storage bin. The bottom of the storage silo is equipped with a screw discharge structure, and a perforated plate is installed at the end of the screw to crush the mud and then put it into the vacuum chamber for degassing. The vacuum chamber output end is connected to a vertical extruder unit. The front end of the vertical extruder unit is connected to the die via a right-angle breaking mechanism, which turns the horizontal extrusion flow direction into a vertical extrusion flow direction.

[0007] Preferably, the storage silo adopts a kneader-type structure, with stirring and moisturizing components on the inner wall, which work in conjunction with the rotation of the stirring blades.

[0008] Preferably, the perforated plate at the end of the screw has a hole diameter of 2 to 8 mm, which is used to pre-crush the mud blocks so that the mud can be more fully vented after entering the vacuum chamber.

[0009] Preferably, the hydraulic feeder is connected to the storage silo to enable automatic feeding.

[0010] Preferably, the right-angle breaking mechanism changes the continuous horizontal extrusion direction to a vertical extrusion direction by a turning angle greater than 90°, thereby changing the product forming from horizontal forming to vertical forming.

[0011] Preferably, the screen changer is installed at the front end of the mold. The screen changer homogenizes the mud and filters out impurities and hard mud lumps from the mud.

[0012] Preferably, a resistance tube is installed at the front end of the mold. The resistance tube is longer than 350 mm, and the end of the resistance tube near the screen changer is the larger end, while the end near the flange and the mold is the smaller end. The larger end and the smaller end are connected by an angled straight line structure, and the angle is greater than 5°.

[0013] Preferably, the transmission rod is mounted on the outer shell of the storage silo via an upper or outer bearing, which makes the rotation of the transmission rod more stable, thereby improving the uniformity of the mud being mixed by the mixing blades.

[0014] Compared with related technologies, the continuous three-in-one molding machine for honeycomb ceramics provided by this utility model has the following beneficial effects: 1. This utility model, through the setting of a storage hopper with a kneading structure and a mixing mechanism consisting of a motor, transmission wheel, transmission belt, transmission rod and mixing blades, can achieve continuous mixing of clay during the storage stage, ensuring that the clay maintains a consistent moisture content and plasticity, avoiding stratification or clumping caused by static storage, and ensuring extrusion stability from the source. Through the cooperation of the screw discharge structure and the perforated plate, larger clay lumps can be effectively broken, giving the clay better fluidity and a larger exposed area before entering the vacuum chamber, thereby significantly improving degassing efficiency. The controllable screw speed also makes the feed rate stable and adjustable, eliminating the problem of inconsistent clay amounts, helping to maintain the continuous pressure and stability of the extrusion flow direction throughout the extrusion section, and significantly improving the dimensional consistency and density of the extruded products.

[0015] 2. By setting a screen changer and a conical resistance tube with a length greater than 350mm at the front end of the mold, impurities and hard particles in the clay can be effectively filtered, further homogenizing the clay and forming a stable extrusion pressure. This makes the surface of the extruded product smoother and the internal structure more compact. The right-angle breaking mechanism converts the original horizontal extrusion flow direction to a vertical flow direction, making the clay forming process more in line with the direction of gravity. This solves the problems of bending and collapse caused by the inconsistency between the extrusion direction and the direction of gravity in traditional horizontal forming, and greatly improves the forming integrity and structural stability of vertical products. This structure also broadens the application range of the extrusion equipment, enabling the equipment to adapt to more types of vertical products and realize three-dimensional spatial forming methods that traditional equipment cannot achieve. It has significant process innovation value and industrial application value. Attached Figure Description

[0020] A preferred embodiment of the honeycomb ceramic continuous three-in-one molding machine provided by this utility model is as follows: Figures 1 to 4 As shown: A continuous three-in-one molding machine for honeycomb ceramics includes: a platform 1, a hydraulic feeder 2, a storage bin 3, a transmission rod 4, a resistance tube 5, a screen changer 6, a flange 7, a hydraulic cylinder 8, a right-angle breaking mechanism 9, a discharge port 10, a screw 11, a vacuum chamber 12, a motor 13, a transmission wheel 14, a transmission belt 15, a stirring blade 16, a vertical extruder unit 17, and a mold 18; Motor 13 drives one of the transmission wheels 14 to rotate. The transmission wheel 14 drives the other transmission wheel and transmission rod 4 to rotate via transmission belt 15. The transmission rod 4 drives the stirring blade 16 to stir and mix the materials inside the storage bin 3. The bottom of the storage silo 3 is equipped with a screw 11 discharge structure. A perforated plate is installed at the end of the screw 11 to crush the mud and then enter the vacuum chamber 12 for degassing. The output end of the vacuum chamber 12 is connected to the vertical extruder unit 17. The front end of the vertical extruder unit is connected to the mold 18 via the right-angle breaking mechanism 9, so that the horizontal extrusion flow direction is changed to the vertical extrusion flow direction.

[0021] In this embodiment, the moving rod 4 drives the stirring blade 16 to stir the material inside the storage bin 3. The screw 11 at the bottom of the storage bin 3 is equipped with a perforated plate to crush the mud and send it into the vacuum chamber 12 for degassing. The output end of the vacuum chamber 12 is connected to the vertical extruder unit 17 and connected to the die 18 through the right-angle breaking mechanism 9, so as to realize the horizontal extrusion flow direction is changed to the vertical extrusion flow direction, and the mud remains uniform and continuous throughout the process.

[0022] In a further preferred embodiment of this utility model, the storage bin 3 adopts a kneader-type structure, with stirring and moisturizing functional components on the inner wall, which are coordinated with the rotation of the stirring blade 16.

[0023] In this embodiment, the rotating agitator blade 16 continuously agitates the mud, ensuring that the mud maintains a consistent moisture content and plasticity within the storage silo 3. This prevents uneven drying or stratification, improves the uniformity of feeding from the screw 11 and the degassing efficiency of the vacuum chamber 12, and provides a stable flow of mud for the vertical extruder unit 17.

[0024] In a further preferred embodiment of this utility model, the perforated plate at the end of the screw 11 has a hole diameter of 2 to 8 mm, which is used to pre-crush the mud blocks so that the mud can be more fully vented after entering the vacuum chamber 12.

[0025] In this embodiment, the surface area of ​​the mud material in the vacuum chamber 12 is increased, improving the air discharge efficiency. The pressure is conveyed by the stabilizing screw 11, allowing the mud material to continuously enter the vertical extruder unit 17, reducing material breakage and bubble defects, and improving product density.

[0026] In a further preferred embodiment of this utility model, the hydraulic feeder 2 is connected to the storage bin 3, which can realize automatic feeding.

[0027] In this embodiment, the hydraulically driven stable conveying of mud allows the equipment to operate continuously for a long time without manual feeding, improving production efficiency. The stability of the hydraulic feeder 2, combined with the rotation of the mixing blades 16, ensures the consistency of mud in the storage bin 3 and improves the feeding effect of the screw 11 and the degassing effect of the vacuum chamber 12.

[0028] In a further preferred embodiment of this utility model, the right-angle breaking mechanism 9 changes the continuous horizontal extrusion direction to a vertical extrusion direction by a turning angle greater than 90°, thereby changing the product forming from horizontal forming to vertical forming.

[0029] In this embodiment, the mud flows smoothly in the direction of gravity, avoiding deformation or collapse caused by gravity during horizontal extrusion. At the same time, the concentrated flow pattern facilitates the formation of stable extrusion pressure by the die 18, improving the dimensional stability and surface quality of the vertically molded product.

[0030] In a further preferred embodiment of this utility model, the screen changer 6 is installed at the front end of the mold 18. The screen changer 6 homogenizes the mud on the one hand and filters out impurities and hard mud lumps in the mud on the other hand.

[0031] In this embodiment, the filter screen homogenizes the mud material and filters out hard particle impurities and unevenly mixed mud lumps, preventing blockage of the mold 18 or scratching of the mold surface, thus improving the life of the mold 18. The filter screen can be replaced without stopping the machine through the screen replacement operation, ensuring production continuity and improving the surface smoothness and molding uniformity of the extruded products. Example

[0032] Based on Example 1, a preferred embodiment of the honeycomb ceramic continuous three-in-one molding machine provided by this utility model is as follows: Figures 1 to 4 As shown: The front end of the mold 18 is equipped with a resistance tube 5. The length of the resistance tube 5 is greater than 350 mm. The end of the resistance tube 5 near the screen changer 6 is the large end, and the end near the flange 7 connected to the mold 18 is the small end. The large end and the small end are connected by an angled straight line structure with an angle greater than 5°.

[0033] In this embodiment, the large end connects to the screen changer 6, and the small end connects to the flange 7 and the mold 18. The large end and the small end are connected by an angled straight line structure with an angle greater than 5 degrees, so that the mud material forms a stable fluid resistance when passing through the resistance pipe 5, the mud material density is uniform, and the molding accuracy and surface smoothness are improved.

[0034] In a further preferred embodiment of this utility model, the transmission rod 4 is mounted on the outer shell of the storage bin 3 via an upper or outer bearing, making the rotation of the transmission rod 4 more stable, thereby improving the uniformity of the mixing of the mud by the stirring blade 16.

[0035] In this embodiment, the stirring blade 16 fully agitates the mud inside the storage bin 3, avoiding dead corners and local hardening, ensuring uniform mixing of the mud, improving the feeding continuity of the screw 11 and the degassing effect of the vacuum chamber 12, and enhancing the molding consistency of the extruded products from the vertical extruder unit 17 and the die 18.

[0036] In summary, during operation, this equipment achieves the entire process of processing mud from its original mixed state to uniform extrusion molding through continuous linkage control of storage, crushing, vacuum degassing, and vertical extrusion molding. First, the hydraulic feeder 2 conveys the pre-treated mud to the storage silo 3 on the platform 1 at a stable pushing speed. The storage silo 3 adopts a kneader-type structure and is equipped with stirring blades 16 inside, which can provide continuous mixing and moisturizing effects, thereby avoiding the problems of stratification, uneven drying and wetting, and clumping of mud during storage. The hydraulic feeder 2 above the storage silo 3 can automatically replenish the material according to the material level of the storage silo 3, so that the entire equipment can maintain continuous operation without manual continuous feeding. In the storage bin 3, after the motor 13 starts, it drives one of the transmission wheels 14 to rotate. The transmission wheel 14 drives the other transmission wheel 14 in conjunction with the transmission belt 15, thereby driving the transmission rod 4 to rotate stably. The transmission rod 4 is fixedly connected to the stirring blade 16. When the transmission rod 4 rotates, the stirring blade 16 forms a forced stirring of the mud inside the storage bin 3, which further homogenizes the mud and avoids hardening or changes in moisture content due to excessive standing time. Continuous stirring can also ensure that the conveying volume in the subsequent screw 11 feeding process is more stable and avoid fluctuations such as sudden feeding or interruption of material. After the mud is evenly mixed, the screw 11 at the bottom of the storage bin 3 starts to rotate under the action of the drive device. When the screw 11 rotates, it pushes the mud gradually towards the discharge end. By adjusting the speed of the screw 11, the feed rate per unit time can be precisely controlled so that the mud entering the subsequent process always presents a uniform and stable flow rate. The end of the screw 11 is provided with a perforated plate with a hole diameter of 2 to 8 mm, which is used to crush the mud so that the mud can more easily expel the internal air after entering the vacuum chamber 12. After entering the vacuum chamber 12, the mud is fully degassed under negative pressure. The mud after pre-crushing by the perforated plate has a larger surface area, which allows the vacuum chamber 12 to remove air bubbles, entrained air or voids in the mud in a short time, avoiding breakage, delamination or porosity defects in the extruded product. The degassed mud is evenly pushed to the continuous extrusion section and conveyed forward under the propulsion of the vertical extruder unit 17. A right-angle breaking mechanism 9 is provided between the extrusion section of the equipment and the mold 18. This mechanism is used to change the original horizontal extrusion direction to a vertical structure. Through the structural design with a turning angle greater than 90°, the mud material maintains continuity and stability during the change of flow direction, thereby realizing the transformation from horizontal molding to vertical extrusion molding. The vertical extrusion method can improve the stability of the product in the direction of gravity after vertical molding and avoid defects such as collapse, bending or displacement. A hydraulic screen changer 6 is installed at the entrance of the mold 18. On the one hand, the screen changer 6 can homogenize the mud through the filter structure, so that it can further stabilize the flow state before passing through the mold 18, and avoid the mud density being uneven or containing a large number of impurities, which would affect the extrusion quality. On the other hand, it can intercept the hard particles, metal fragments or impurities remaining in the mud, ensuring that the mud entering the mold 18 has high purity, thereby improving the consistency and appearance quality of the final molded product.

[0037] The resistance tube 5 installed at the front end of the mold 18 is longer than 350 mm and adopts a tapered structure that gradually transitions from the large end to the small end with a transition angle of more than 5°. This structure forms a certain fluid resistance during the extrusion of the clay, so that the clay is homogenized twice before entering the mold 18 and a stable extrusion pressure is established. The angled structure avoids the sudden change in flow rate caused by the sudden reduction in diameter, so that the clay is uniformly compressed along the inner wall of the resistance tube 5, which helps to improve the compactness and dimensional stability of the product after the mold.
