Description

Technical Field

[0001] The present invention relates to the technical field of brick making equipment, and in particular to brick making equipment and a brick making method. Background Art

[0002] In the production process of ceramic tile blanks, the roller press is a key forming equipment. In the traditional roller press production process, the ceramic powder is transported to the compacting area of ​​the roller press by a conveyor belt. In this area, the upper pressing roller and the lower pressing roller work together to apply pressure to the powder, thereby realizing the roller forming of the ceramic tile blank.

[0003] However, due to the free-flowing characteristics of ceramic powders, when they are laid on the conveyor belt, the two sides tend to collapse, forming a trapezoidal cross-section. After compaction, the insufficient thickness of the two sides of the powder is prone to defects, affecting the quality of the ceramic tile. In the prior art, it is usually necessary to trim the sides of the powder to form a rectangular cross-section. However, this process increases the complexity and cost of production, and may also introduce new errors and defects.

[0004] Therefore, there is an urgent need for a brick-making device and a brick-making method to overcome the above-mentioned defects. Summary of the invention

[0005] In order to overcome at least one of the defects of the above-mentioned prior art, one of the objects of the present invention is to provide a brick-making equipment, which pre-compacts the powder by setting a hopper, and at the same time forms a powder layer of uniform thickness before the powder enters the compaction space, without the need for additional side trimming operations, and avoids the problem of voids or bubbles inside the molded bricks due to the powder layer containing too much air.

[0006] The second object of the present invention is to provide a brick-making method, which can meet the production requirements of bricks of different thicknesses and widths, and the cross-sectional shape of the produced bricks is uniform, reducing the trimming amount of the molded bricks and avoiding waste.

[0012] Furthermore, the brick-making equipment includes a side guard, and the side guard includes a side guard strip, and the side guard strip is arranged on both sides of the compaction space, and a retaining gap is formed between the side guard strips on both sides of the compaction space, and the retaining gap is connected with the guide channel.

[0013] Furthermore, the discharge port assembly includes a width adjustment plate, which is arranged on both sides of the guide channel, and a discharge gap is formed between the width adjustment plates on both sides of the guide channel, wherein the width adjustment plate on one side can approach or move away from the width adjustment plate on the other side so that the width of the discharge gap can be adjusted; one end of the side guard strip is connected to the width adjustment plate.

[0014] Furthermore, the feeding section has two end walls and two side walls that are arranged opposite to each other, and a feeding gap is formed between the two end walls. The width of the feeding gap gradually decreases from one end close to the feeding section to one end close to the guiding section; the two side walls are arranged in parallel.

[0015] Furthermore, the feeding section is provided with a feeding screw, and the feeding screw is used to push the powder toward the feeding section during rotation.

[0016] Furthermore, the feeding assembly includes two first baffles and two second baffles, the two first baffles are respectively arranged on both sides of the feeding section, and a blanking gap is formed between the two first baffles; the two second baffles are respectively arranged on both sides of the feeding section, and a transition gap is formed between the two second baffles, and the width of the transition gap is greater than the width of the blanking gap.

[0017] Furthermore, the widths of the blanking interval and the transition interval are both adjustable.

[0018] Furthermore, the brick-making equipment includes a material receiving device, which includes an active rotating part, a passive rotating part and a conveyor belt.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0036] Embodiment 1

[0037] See also Figures 1 to 3 The present invention discloses a brick making device, which includes a forming roller assembly 2 and a feeding assembly; Figure 1 or Figure 3 The forming roller assembly 2 includes a first forming roller 21 and a second forming roller 22. The first forming roller 21 and the second forming roller 22 are arranged opposite to each other in the vertical direction, and a compaction space 23 is formed between the first forming roller 21 and the second forming roller 22. Figure 1 The feeding assembly includes a hopper 1, and a feeding channel 10 is provided in the hopper 1. Specifically, the feeding channel 10 includes a feeding section 15 and a feeding section 16 distributed from top to bottom. The feeding section 15 extends in the vertical direction, and the feeding section 16 is an arc section; and the inner diameter of the feeding section 16 is smaller than the inner diameter of the feeding section 15, so that the feeding section 16 can pre-compact the material when receiving the material. Among them, one end of the feeding section 16 extends to the compaction space 23 and passes through the compaction space 23, and the other end of the feeding section 16 is connected to the feeding section 15.

[0038] Based on this structure, when using the brick-making equipment of the present application, the powder material (such as ceramic powder) required for brick-making is first added into the hopper 1 from the feed end 11. After the powder material enters the hopper 1, it first passes through the vertically extending feed section 15; the inner diameter of the feed section 15 is large, which facilitates the smooth entry and initial accumulation of the material. Then the powder material enters the more compact feeding section 16, is initially compacted in the feeding section 16, and is led out into the compaction space 23 from the discharge end 12 of the feeding section 16.

[0039] The part of the feeding section 16 extending in the horizontal direction has a rectangular vertical cross section, or the vertical cross section at the discharge end 12 of the feeding section 16 has a rectangular vertical cross section, so that the powder layer has a square cross section with uniform thickness when it is output from the discharge end 12.

[0040] Since the feeding section 16 is an arc section and its inner diameter is smaller than that of the feeding section 15, the powder is forced to be squeezed when passing through, reducing the air content in the powder, thereby reducing the fluffiness and achieving the effect of pre-compaction. Subsequently, the powder material will form a powder layer with uniform thickness at the discharge end 12 of the feeding section 16. Since the discharge end 12 of the feeding section 16 extends to the compaction space 23, the feeding section 16 not only guides the powder material from the vertical direction to the horizontal direction, but also pre-compacts the powder material through the inner wall structure, so that the powder material forms a powder layer with uniform thickness before entering the compaction space 23.

[0041] Then, the pre-compacted powder layer is sent to the compaction space 23 of the forming roller assembly 2 through the feeding section 16. Then the first forming roller 21 and the second forming roller 22 begin to rotate towards each other to further compact and form the powder layer. It should be noted that if there is too much air in the powder layer, during the pressing and forming process, the air may be compressed and remain inside the brick 5, resulting in cavities or bubbles inside the brick 5. The cavities or bubbles will reduce the density and strength of the brick 5, making it easy to have defects such as cracks and delamination during subsequent processing or use. In addition, the powder layer containing too much air requires greater pressure to be compacted, thereby increasing the energy consumption of the equipment. At the same time, due to the poor compaction effect, multiple pressings may be required to achieve the required density and strength, further increasing energy consumption.

[0042] The present application performs a pre-compacting treatment on the powder layer before compacting it, which can significantly reduce the air content in the powder layer and make the powder more tightly combined. In addition, the thickness of the powder layer is more uniform, avoiding the problem of the traditional method where the two sides collapse due to the free flow of powder to form a trapezoidal cross section. With the continuous pressing of the forming roller, the powder layer is gradually compacted and forms a brick 5 with a rectangular cross section.

[0043] Then, the formed brick 5 is output from the forming roller assembly 2 and can be directly subjected to subsequent drying, firing and other treatments. Since the cross-sectional shape of the brick 5 is uniform and meets the standard, the redundant part that needs to be corrected by trimming is reduced, that is, the trimming amount of the formed brick is reduced, and the production cost and complexity are reduced.

[0044] Thus, the voids in the powder are eliminated by the pre-compacting process of the feeding section 16, ensuring the uniform distribution of the powder layer before entering the compacting space 23, thereby reducing the problems of brick deformation or insufficient strength due to uneven thickness or the presence of bubbles, and helping to improve the molding accuracy and overall quality of the brick 5. Since there is no need to trim the side of the powder layer before pressing and molding, and there are fewer edge portions that need to be trimmed after the brick 5 is formed, material waste and labor costs in the production process are reduced.

[0045] Further, the brick making device includes a discharge port assembly, and the discharge port assembly includes a guide section; Figure 1 The feeding section 16 is connected to the compacting space 23 by a guide section, and the guide section is detachably connected to the feeding section 16. A guide channel 14 is provided in the guide section, and the height and width of the guide channel 14 are adjustable.

[0046] Based on this structure, the discharge port assembly is arranged at the discharge end of the hopper 1. When in use, the guide section is first connected to the feeding section 16 to ensure that the connection is firm and stable. After the powder materials are pre-compacted by the feeding section 16, they will enter the guide section. In the guide section, the powder materials will continue to move along the guide channel 14, gradually adjust their shape and thickness, and form a powder layer with uniform thickness at the end of the guide channel 14.

[0047] The guide section extends in the horizontal direction, and the vertical cross section of the guide section is rectangular. According to actual needs, guide sections of different specifications can be selected, specifically guide sections with guide channels 14 of different heights and widths, and the guide section and the feeding section 16 can be detachably connected by plugging and splicing, which is convenient for replacing the guide section, thereby realizing the height adjustment and width adjustment of the guide channel 14 to meet the production needs of brick blanks 5 of different sizes and shapes.

[0048] At the same time, the interval between the first forming roller 21 and the second forming roller 22 in the vertical direction can be adjusted so that the height of the compaction space 23 formed by the first forming roller 21 and the second forming roller 22 can adapt to the production requirements of bricks 5 of different thicknesses. Specifically, a hydraulic cylinder or a pneumatic cylinder can be used to control the lifting and lowering of the first forming roller 21, wherein the cylinder body is fixed on the frame of the equipment, and the piston rod is connected to the mounting seat of the first forming roller 21.

[0049] Therefore, the setting of the guide section enables the equipment to adapt to the production requirements of bricks 5 of different sizes. And the existence of the guide section enables the powder material to be better adjusted and pre-compacted before entering the compacting space 23, which helps to reduce the flow resistance and energy consumption of the material during the compaction process, and improve the compaction efficiency and the quality of the brick 5.

[0050] In addition, some transition structures (such as gradient plates, guide plates, etc.) can be provided at the connection between the feeding section 16 and the guide section to further ensure the smooth transition of the powder material and reduce the leakage or accumulation of powder at the connection.

[0051] Further, see Figure 2 and Figure 3 The brick making equipment includes a side guard 3. Specifically, the side guard 3 includes a side guard strip 31. The side guard strip 31 is arranged on both sides of the compaction space 23, and a retaining interval is formed between the side guard strips 31 on both sides of the compaction space 23. The retaining interval is connected to the guide channel 14.

[0052] Thus, after the powder layer is guided out of the guide channel 14, it enters the retaining interval, and the two sides of the powder layer are restrained by the retaining strips 31, so that the powder will not flow outward and collapse, and the powder layer can maintain a uniform thickness. At the same time, when the forming roller assembly 2 is pressed, the retaining strips 31 can prevent the powder from diffusing to both sides during the compaction process, thereby ensuring that the final pressed brick 5 has a uniform thickness without the need for edge cutting.

[0053] In addition, the side guard 3 also includes a second driving member, the power output end of the second driving member is connected to the side guard strip 31, and the second driving member can drive the side guard strips 31 on both sides to move closer to or away from each other, thereby adjusting the width of the barrier interval to make the width of the barrier interval match the width of the guide channel, so that when receiving the powder material layer guided by the guide channel, the powder material layer can be prevented from collapsing to both sides. The second driving member can be a driving form such as an electric push rod, a cylinder, a servo motor and a ball screw combination.

[0054] Further, see Figure 2 The discharge port assembly further includes a width adjustment plate 32. Specifically, the width adjustment plates 32 are disposed on both sides of the guide channel 14, and a discharge interval is formed between the width adjustment plates 32 on both sides of the guide channel 14, wherein the width adjustment plate 32 on one side can move closer to or farther from the width adjustment plate 32 on the other side, so that the width of the discharge interval can be adjusted. In addition, one end of the sidewall strip 31 is connected to the width adjustment plate 32.

[0055] It should be noted that when the width adjustment plates 32 are not provided on both sides of the guide channel 14, the width of the powder layer guided through the guide channel 14 is equal to the width of the guide channel 14. In this embodiment, by providing the width adjustment plates 32 on both sides of the guide channel 14, the width of the powder layer guided through the guide channel 14 is equal to the distance between the width adjustment plates 32 on both sides, so as to meet the production requirements of more bricks 5 of different specifications.

[0056] On the basis of this structure, when using the discharge port assembly, a guide segment that meets the thickness requirement of the brick blank 5 can be selected from a plurality of preset guide segments according to the thickness of the brick blank 5 to be produced, and the inlet width of the guide segment is the same as the outlet width of the feeding segment 16, so that the guide segment can be directly and seamlessly connected to the feeding segment 16 to avoid leakage or accumulation of powder during the transition process.

[0057] Then, according to the width of the selected brick 5, the width adjustment plate 32 in the guide section is adjusted. This operation can be achieved by manual adjustment, mechanical device or automatic control system to adjust the width of the discharge interval to match the width of the selected brick 5.

[0058] Then one end of the side guard strip 31 is connected to the width adjustment plate 32, so that the powder layer can maintain a uniform thickness and a constant width when passing through the guide section and entering the compaction space 23, and the powder on both sides will not collapse due to the inconsistent width of the barrier interval, thereby causing uneven compaction or poor molding.

[0059] In addition, one end of the side guard strip 31 can also be connected to one end of the width adjustment plate 32, so that when the width adjustment plate 32 is moved to adjust the discharge interval width, the side guard strip 31 will also move accordingly, thereby automatically keeping the width of the barrier interval consistent with the discharge interval width.

[0060] Thus, the guide section can be replaced quickly and the width adjustment plate 32 can be adjusted, which reduces the time required for replacing the mold and setting up the equipment, improves production efficiency, and at the same time improves the flexibility and adaptability of the brick-making equipment.

[0061] Further, the feeding section 16 has two end walls and two side walls arranged opposite to each other, wherein a feeding gap 13 is formed between the two end walls, and the width of the feeding gap 13 gradually decreases from one end close to the feeding section 15 to one end close to the guiding section. In addition, the two side walls are arranged in parallel.

[0062] It should be noted that when the powder forms a powder layer in the feeding section 16, the two end walls respectively contact the two larger end faces of the powder layer, and the two side walls respectively contact the two smaller side faces of the powder layer, so the width of the feeding interval 13 is the thickness of the powder layer.

[0063] When the width of the feeding interval 13 gradually decreases along the conveying direction, the two end faces of the powder layer are gradually squeezed by the end wall of the feeding section 16, further reducing the air inside the powder layer. In addition, the large surface extrusion of the end wall is more conducive to the uniform distribution of the powder in the powder layer, so as to form a more uniform thickness distribution.

[0064] In addition, the two side walls of the feeding section 16 are arranged in parallel, which can constrain the powder at the side of the powder layer to prevent the powder from lateral diffusion or deformation during transportation, so that the powder layer forms a powder layer with uniform thickness in the feeding section 16 and at the outlet of the feeding section 16.

[0065] Furthermore, the feeding section 15 is provided with a feeding screw 17 , and the feeding screw 17 is used to push the powder material toward the feeding section 16 during the rotation process.

[0066] Specifically, the feeding screw 17 extends along the conveying direction of the powder material; the driving motor of the feeding screw 17 is started to make the feeding screw 17 start to rotate, and its spiral blades will continuously push the powder material from the inlet end of the feeding section 15 to the feeding section 16. In this process, the powder material will be squeezed and sheared by the spiral blades, which helps to discharge the air inside it and make the powder more compact.

[0067] At the same time, when the powder layer reaches the outlet of the feeding section 16, the continuous rotation of the feeding screw 17 and the self-gravity of the powder layer provide a continuous driving force for the powder layer, so that the powder layer can smoothly enter the compacting space 23 and complete the compaction process.

[0068] Further, see Figure 2 The feeding assembly includes two first baffles 18 and two second baffles 19. Specifically, the two first baffles 18 are respectively arranged on both sides of the feeding section 15, and a blanking interval is formed between the two first baffles 18; the two second baffles 19 are respectively arranged on both sides of the feeding section 16, and a transition interval is formed between the two second baffles 19. The width of the transition interval is greater than the width of the blanking interval.

[0069] Based on this structure, when conveying powder material, the powder material in the feed section 15 enters the feeding section 16 with the width of the blanking interval, then enters the guide section with the width of the transition interval, and finally enters the compacting space 23 with the width of the discharge interval.

[0070] The feeding screw 17 is arranged in the middle of the feeding section 15, so the moving speed of the powder material in the middle of the feeding section 15 is greater than the moving speed of the powder material on both sides of the feeding section 15. In this embodiment, by setting the drop interval between the two first baffles 18 to be smaller, the powder material is more concentrated in the middle of the feeding section 15, and the powder material can enter the feeding section 16 more under the push of the feeding screw 17, reducing the retention and long-term accumulation of powder on both sides of the feeding section 15, reducing the possibility of dead material, and improving the utilization rate of powder.

[0071] In addition, the transition interval serves as a buffer area for the powder material from the feed section 15 to the guide section, ensuring that the powder can transition smoothly and avoid accumulation or blockage during the conversion process.

[0072] Furthermore, the widths of the blanking interval and the transition interval are both adjustable.

[0073] Therefore, the blanking interval between the two first baffles 18 can be manually adjusted first, and then a guide section with a guide channel 14 of suitable height can be selected and connected to the hopper 1, and then the position of the width adjustment plate 32 in the guide section can be adjusted by a driving member (such as a cylinder, etc.) to adjust the discharge interval, and then the transition interval between the two second baffles 19 can be adjusted by another driving member (such as a cylinder, etc.) so that the blanking interval and the discharge interval are transitionally connected through the transition interval.

[0074] Among them, the width of the discharge interval needs to be adjusted according to the width of the brick 5 to be pressed and formed, the width of the blanking interval can be adjusted according to the amount of powder to be transported, and the width of the blanking interval is set smaller than the width of the discharge interval, and the width of the transition interval is between the discharge interval and the blanking width.

[0075] In addition, one end of the width adjustment plate 32 can be detachably connected to one end of the second baffle 19, so that when the transition interval between the two second baffles 19 is adjusted by the driving member, the width adjustment plate 32 can be driven to move together, thereby adjusting the blanking interval.

[0076] Further, see Figure 1 The brick making equipment includes a material receiving device 4. Specifically, the material receiving device 4 includes an active rotating part, a passive rotating part and a conveyor belt. The conveyor belt is arranged around the outer periphery of the active rotating part and the passive rotating part. The active rotating part is used to drive the conveyor belt to rotate, and the conveyor belt is used to receive the bricks 5 sent out from the compaction space 23.

[0077] Based on this structure, when the compacting space 23 completes the pressing of the brick 5, the receiving device 4 starts to work. First, the active rotating part (such as a motor-driven roller) is started, and the conveyor belt starts to rotate through friction. The brick 5 enters the receiving end of the transmission belt under the push of the forming roller assembly 2. As the conveyor belt rotates continuously, the conveyor belt transmits the received brick 5 to the next process.

[0078] The speed and direction of the conveyor belt can be achieved by adjusting the rotation speed and direction of the active rotating parts to meet different production needs.

[0079] In addition, the receiving device 4 can also be in the form of multiple conveying rollers for conveying. Specifically, multiple conveying rollers are arranged at the exit of the compacting space 23, and the multiple conveying rollers rotate synchronously in the same direction. The green bricks 5 are led out of the compacting space 23 and received by the conveying rollers, and the conveying rollers output the green bricks 5 during the rotation process. It can be understood that the receiving device 4 can also be other transmission structures in the prior art.

[0080] In summary, the present application directly outputs a powder layer of uniform thickness through the hopper 1, and the hopper 1 is arranged in the vertical direction, eliminating the feeding conveyor belt commonly used in traditional brick-making equipment, reducing the maintenance cost of the equipment, and improving the reliability and stability of the equipment. At the same time, the horizontal occupied volume of the brick-making equipment of the present application is greatly reduced, making the overall device more compact and smaller in size.

[0081] Embodiment 2

[0082] This embodiment discloses a brick making method, which can be applied to the brick making equipment in the first embodiment. Specifically, the brick making method comprises the following steps:

[0083] Step S1: First, after filling the hopper 1 with powder, the powder is accumulated in the feeding section 15 of the feeding channel 10. A feeding screw 17 can be set in the feeding section 15 to push the powder to the feeding section 16 of the feeding channel 10, and the powder in the feeding section 16 is pushed forward by the powder in the feeding section 15, wherein the powder is pre-compacted in the feeding section 16 and a powder layer of uniform thickness is formed at the discharge port of the feeding section 16.

[0084] Step S2: Subsequently, the powder layer at the discharge port of the feeding section 16 enters the compacting space 23 under the push of the powder in the feeding channel 10. In the compacting space 23, the first forming roller 21 and the second forming roller 22 rotate towards each other, and the two forming rollers work together to compact the powder layer to form a brick 5, and then the brick 5 is output by the receiving device 4.

[0085] It should be noted that, between step S1 and step S2, step S3 can be added: guide sections of different specifications are arranged between the compaction space 23 and the feeding section 16, wherein the powder layer at the discharge port of the feeding section 16 enters the guide channel 14 of the guide section under the push of the powder in the feeding channel 10, and the powder forms powder material layers of different thicknesses in the guide channel 14.

[0086] Therefore, through the precise feeding and pre-compacting processing of the feeding section 16, and the optional further adjustment of the powder layer by the guide section, it is ensured that most of the air inside the powder layer entering the compacting space 23 is discharged, and the powder layer has a uniform thickness and a stable structure, so that the cross-sectional shape of the final brick 5 is uniform and meets the established quality standards.

[0087] Among them, the brick-making method of the present application realizes a continuous production process from powder to brick blanks 5. The push of the feeding screw 17, the compaction of the forming rollers and the output of the material receiving device 4 together constitute an efficient and stable production system that meets the needs of large-scale production. This system can continuously and stably output high-quality brick blanks 5. It is not easy for cavities, bubbles, etc. to exist inside the formed brick blanks 5, and it is not easy for cracks, stratification and other defects to appear on the surface of the brick blanks 5. In addition, since there are fewer edge parts that need to be trimmed after the forming of the formed brick blanks 5, the material waste and labor costs in the production process are reduced. The preparation method of the present application shortens the powder conveying process and reduces external interference. This not only improves the utilization rate of the equipment, but also ensures the stable operation of the production line, further improving the overall production efficiency.

[0088] In addition, by replacing guide segments of different specifications, the preparation method of the present application can easily adapt to the production requirements of bricks 5 of different thicknesses and sizes. This flexibility makes the method applicable to a variety of application scenarios.

[0089] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
