Description

Technical Field

[0001] This utility model relates to the field of brick-making equipment technology, and in particular to a brick-making device. Background Technology

[0002] In the production process of ceramic tile blanks, the roller press is a key forming equipment. In the traditional roller press production process, ceramic powder is transported to the compaction zone of the roller press via a conveyor belt. In this zone, the upper and lower pressure rollers work together to apply pressure to the powder, thereby achieving the roller pressing and forming of the ceramic tile blank.

[0003] However, due to the free-flowing nature of ceramic powder, it often collapses on both sides when laid on a conveyor belt, forming a trapezoidal cross-section. After compaction, this type of powder, with insufficient thickness on both sides, is prone to defects, affecting the quality of the ceramic brick. Current technology typically requires trimming the sides of the powder to form a rectangular cross-section. However, this process increases production complexity and cost, and may also introduce new errors and defects.

[0004] Therefore, there is an urgent need for a brick-making machine to overcome the above-mentioned defects. Utility Model Content

[0005] In order to overcome at least one of the defects of the prior art, the purpose of this utility model is to provide a brick making equipment that pre-compacts the powder by setting a hopper, so that the powder forms a uniform powder layer before entering the compaction space, eliminating the need for additional side trimming operations and avoiding problems such as voids or air bubbles inside the formed brick blank due to too much air in the powder layer.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] A brick-making device, comprising,

[0008] The forming roller assembly includes a first forming roller and a second forming roller, wherein the first forming roller and the second forming roller are arranged opposite each other in the vertical direction, and a compaction space is formed between the first forming roller and the second forming roller;

[0009] A feeding assembly includes a hopper with a feeding channel inside. The feeding channel includes an infeed section and a feeding section distributed from top to bottom. The infeed section extends vertically, and the feeding section is arc-shaped. The inner diameter of the feeding section is smaller than that of the infeed section. The feeding section is used to pre-compact the material when receiving it. One end of the feeding section extends into and communicates with the compaction space, and the other end of the feeding section communicates with the infeed section.

[0010] Furthermore, the brick-making equipment includes a discharge port assembly, which includes a guide section. The feeding section and the compaction space are connected by the guide section, and the guide section and the feeding section are detachably connected. The guide section is provided with a guide channel, the height and width of which are adjustable.

[0011] Furthermore, the brick-making equipment includes a side-blocking component, which includes a side-blocking strip. The side-blocking strip is disposed on both sides of the compaction space, and a blocking interval is formed between the side-blocking strips on both sides of the compaction space. The blocking interval is in communication with the guide channel.

[0012] Furthermore, the discharge port assembly includes a width adjustment plate, which is disposed on both sides of the guide channel, and a discharge interval is formed between the width adjustment plates on both sides of the guide channel. The width adjustment plate on one side can move closer to or further away from the width adjustment plate on the other side so that the width of the discharge interval is adjustable. One end of the edge guard strip is connected to the width adjustment plate.

[0013] Furthermore, the feeding section has two end walls and two side walls arranged opposite to each other, and a feeding interval is formed between the two end walls. The width of the feeding interval gradually decreases from one end near the feed section to the one end near the guide section; the two side walls are arranged in parallel.

[0014] Furthermore, the feeding section is equipped with a feeding screw, which is used to push the powder towards the feeding section during rotation.

[0015] Furthermore, the feeding assembly includes two first baffles and two second baffles. The two first baffles are respectively disposed on both sides of the feeding section, and a discharge interval is formed between the two first baffles. The two second baffles are respectively disposed on both sides of the feeding section, and a transition interval is formed between the two second baffles. The width of the transition interval is greater than the width of the discharge interval.

[0016] Furthermore, the widths of both the material dropping interval and the transition interval are adjustable.

[0017] Furthermore, the feeding assembly includes a first driving member, the power output end of which is connected to the second baffle. The first driving member is used to drive the two second baffles to move closer to or further away from each other.

[0018] Furthermore, the brick-making equipment includes a receiving device, which includes an active rotating component, a passive rotating component, and a conveyor belt. The conveyor belt surrounds the active rotating component and the passive rotating component. The active rotating component drives the conveyor belt to rotate, and the conveyor belt receives the brick blanks sent out by the compaction space.

[0019] In summary, the brick-making equipment provided by this utility model has the following technical effects:

[0020] 1) The brick-making equipment of this application, when conveying powder, sets the upper and lower parts of the hopper to different shapes, especially setting the feeding section as an arc section and reducing the inner diameter of the feeding section. This causes the powder to be compressed when passing through the feeding section, reducing the air content in the powder and thus reducing its bulkiness, achieving a pre-compaction effect. At the same time, the powder layer output from the discharge end has a square cross-section of uniform thickness. After being compacted, such a powder layer can produce brick blanks with a uniform cross-sectional shape that meet the standards, and the brick blanks are less likely to have voids or air bubbles inside, resulting in better quality.

[0021] 2) The brick-making equipment of this application does not require trimming the sides of the powder layer before pressing and molding, and reduces the excess part that needs to be corrected by cutting the edges after the brick blank is formed, thus reducing material waste and labor costs in the production process.

[0027] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element 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 this utility model.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0030] See Figures 1 to 3 This utility model discloses a brick-making device, which includes a forming roller assembly 2 and a feeding assembly; see reference. 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 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. (See reference...) Figure 1 The feeding assembly includes a hopper 1, which contains a feeding channel 10. Specifically, the feeding channel 10 includes an infeed section 15 and a feeding section 16 distributed from top to bottom. The infeed section 15 extends vertically, and the feeding section 16 is arc-shaped. Furthermore, the inner diameter of the feeding section 16 is smaller than that of the infeed section 15, so that the feeding section 16 can pre-compact the material when receiving it. One end of the feeding section 16 extends into and communicates with the compaction space 23, while the other end of the feeding section 16 communicates with the infeed section 15.

[0031] Based on this structure, when using the brick-making equipment of this application, the powdered material (such as ceramic powder) required for brick making is first added to the hopper 1 through the feed end 11. After the powdered material enters the hopper 1, it first passes through the vertically extending feed section 15; the inner diameter of the feed section 15 is relatively large, which facilitates the smooth entry and initial accumulation of the material. Subsequently, the powdered material enters the more compact feeding section 16, where it is initially compacted, and is then discharged from the discharge end 12 of the feeding section 16 into the compaction space 23.

[0032] In particular, the vertical cross-section of the feeding section 16 extending horizontally is rectangular, or the vertical cross-section of the feeding section 16 at the discharge end 12 is rectangular, so that the powder layer output from the discharge end 12 has a square cross-section with uniform thickness.

[0033] Because the feeding section 16 is arc-shaped and its inner diameter is smaller than that of the infeed section 15, the powder is forced to be compressed as it passes through, reducing the air content in the powder and thus reducing its bulkiness, achieving a pre-compaction effect. Subsequently, the powder material forms a uniformly thick powder layer at the outlet end 12 of the feeding section 16. Since the outlet end 12 of the feeding section 16 extends into 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 its inner wall structure, so that the powder material forms a uniformly thick powder layer before entering the compaction space 23.

[0034] Therefore, the pre-compacted powder layer is fed through the feeding section 16 into the compaction space 23 of the forming roller assembly 2. Subsequently, the first forming roller 21 and the second forming roller 22 begin to rotate in opposite directions, further compacting and shaping the powder layer. It should be noted that if the powder layer contains too much air, this air may be compressed and remain inside the brick blank 5 during the pressing process, resulting in voids or air bubbles inside the brick blank 5. These voids or air bubbles will reduce the density and strength of the brick blank 5, making it prone to defects such as cracks and delamination during subsequent processing or use. Furthermore, a powder layer containing too much air requires greater pressure to compact, thus increasing the equipment's energy consumption. At the same time, due to poor compaction, multiple pressing operations may be required to achieve the desired density and strength, further increasing energy consumption.

[0035] This application pre-compacts the powder layer before compaction, which significantly reduces the air content in the powder layer, making the powder more tightly bound together. Furthermore, the powder layer thickness is more uniform, avoiding the trapezoidal cross-section problem caused by the free flow of powder leading to collapse on both sides, as seen in traditional methods. With continuous pressing by the forming rollers, the powder layer is gradually compacted and forms a brick blank 5 with a rectangular cross-section.

[0036] Next, the formed brick blank 5 is output from the forming roller assembly 2 and can be directly subjected to subsequent drying, firing and other processes. Since the cross-sectional shape of the brick blank 5 is uniform and conforms to the standard, the excess part that needs to be corrected by trimming is reduced, that is, the amount of trimming of the formed brick blank is reduced, thus reducing production costs and complexity.

[0037] Therefore, the pre-compaction treatment in the feeding section 16 eliminates voids in the powder, ensuring a uniform distribution of the powder layer before it enters the compaction space 23. This reduces problems such as brick deformation or insufficient strength caused by uneven thickness or air bubbles, and helps improve the forming accuracy and overall quality of the brick blank 5. Since there is no need to trim the sides of the powder layer before pressing and molding, and the edge trimming required after the brick blank 5 is formed is minimal, material waste and labor costs in the production process are reduced.

[0038] Furthermore, the brick-making equipment includes a discharge port assembly, and the discharge port assembly includes a guide section; see below. Figure 1 The feeding section 16 and the compaction space 23 are connected by a guide section, and the guide section and the feeding section 16 are detachably connected. The guide section is provided with a guide channel 14, and the height and width of the guide channel 14 are adjustable.

[0039] Based on this structure, the discharge port assembly is located at the discharge end of the hopper 1. In use, the guide section is first connected to the feeding section 16, ensuring a firm and stable connection. After the powder material is pre-compacted through the feeding section 16, it enters the guide section. Within the guide section, the powder material continues to move along the guide channel 14, gradually adjusting its shape and thickness, and forming a uniformly thick powder layer at the end of the guide channel 14.

[0040] The guide section extends horizontally and has a rectangular vertical cross-section. Different specifications of guide sections can be selected according to actual needs, specifically guide sections with different heights and widths of the guide channel 14. The guide section and the feeding section 16 can be detachably connected by plugging or splicing, which facilitates the replacement of the guide section. This allows for the adjustment of the height and width of the guide channel 14 to meet the production needs of brick blanks 5 of different sizes and shapes.

[0041] Meanwhile, the vertical spacing between the first forming roller 21 and the second forming roller 22 is adjustable 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 needs of brick blanks 5 of different thicknesses. Specifically, the lifting and lowering of the first forming roller 21 can be controlled by a hydraulic cylinder or a pneumatic cylinder, wherein the cylinder body is fixed on the frame of the equipment, and the piston rod is connected to the mounting base of the first forming roller 21.

[0042] Therefore, the guide section allows the equipment to adapt to the production needs of brick blanks 5 of different sizes. Furthermore, the presence of the guide section allows the powder material to be better adjusted and pre-compacted before entering the compaction space 23, which helps reduce the flow resistance and energy consumption of the material during the compaction process, improving compaction efficiency and the quality of the brick blanks 5.

[0043] In addition, at the connection between the feeding section 16 and the guiding section, some transition structures (such as gradient plates, guide plates, etc.) can be set to further ensure the smooth transition of powder materials and reduce powder leakage or accumulation at the connection.

[0044] 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 set on both sides of the compaction space 23, and a blocking interval is formed between the side guard strips 31 on both sides of the compaction space 23. The blocking interval is connected to the guide channel 14.

[0045] Therefore, after the powder layer is discharged from the guide channel 14, it enters the retaining interval, and the two sides of the powder layer are constrained by the retaining strips 31, so 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 pressing, the retaining strips 31 can prevent the powder from spreading to both sides during the compaction process, thereby ensuring that the brick blank 5 formed by the final pressing has a uniform thickness and does not require edge trimming.

[0046] In addition, the edge retainer 3 also includes a second driving component. The power output end of the second driving component is connected to the edge retainer strip 31. The second driving component can drive the edge retainer strips 31 on both sides to move closer or further apart, thereby adjusting the width of the retaining interval so that the width of the retaining interval matches the width of the guide channel. This prevents the powder material layer from collapsing to both sides when receiving the powder material layer discharged from the guide channel. The second driving component can be a combination of an electric push rod, a cylinder, a servo motor, and a ball screw.

[0047] Further, see Figure 2 The discharge port assembly also includes a width adjustment plate 32. Specifically, the width adjustment plate 32 is 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. The width adjustment plate 32 on one side can move closer to or further away from the width adjustment plate 32 on the other side, so that the width of the discharge interval is adjustable. In addition, one end of the edge strip 31 is connected to the width adjustment plate 32.

[0048] 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 discharged through the guide channel 14 is equal to the width of the guide channel 14. In this embodiment, by providing width adjustment plates 32 on both sides of the guide channel 14, the width of the powder layer discharged through the guide channel 14 is equal to the distance between the two width adjustment plates 32, so as to meet the production needs of more brick blanks 5 of different specifications.

[0049] Based on this structure, when using the discharge port assembly, a guide section that meets the thickness requirements of the brick blank 5 can be selected from a variety of preset guide sections according to the thickness of the brick blank 5 to be produced. Furthermore, the inlet width of the guide section is the same as the outlet width of the feeding section 16, so that the guide section can be directly and seamlessly connected to the feeding section 16, avoiding leakage or accumulation of powder during the transition process.

[0050] Then, based on the width of the selected brick blank 5, adjust the width adjustment plate 32 in the guide section. 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 blank 5.

[0051] Then, one end of the baffle strip 31 is connected to the width adjustment plate 32. As a result, the powder layer can maintain a uniform thickness and a constant width when it passes through the guide section and enters the compaction space 23. The powder on both sides will not collapse due to the inconsistent width of the baffle interval, which would lead to uneven compaction or poor molding.

[0052] Alternatively, one end of the baffle strip 31 can be connected to one end of the width adjustment plate 32. In this way, when the width adjustment plate 32 is moved to adjust the discharge interval width, the baffle strip 31 will also move accordingly, thereby automatically keeping the width of the baffle interval consistent with the discharge interval width.

[0053] This allows for quick replacement of the guide section and adjustment of the width adjustment plate 32, reducing the time required for mold replacement and equipment setup, and improving production efficiency; at the same time, it enhances the flexibility and adaptability of the brick-making equipment.

[0054] Furthermore, the feeding section 16 has two end walls and two side walls arranged opposite to each other, wherein a feeding interval 13 is formed between the two end walls, and the width of the feeding interval 13 gradually decreases from the end near the feed section 15 to the end near the guide section. In addition, the two side walls are arranged in parallel.

[0055] It should be noted that when the powder forms a powder layer in the feeding section 16, the two end walls contact the two larger end faces of the powder layer, and the two side walls contact the two smaller side faces of the powder layer. Therefore, the width of the feeding interval 13 is equal to the thickness of the powder layer.

[0056] As the width of the feeding interval 13 gradually decreases along the conveying direction, the two end faces of the powder layer are subjected to increasingly stronger compression from the end walls of the feeding section 16, which further reduces the air inside the powder layer. Moreover, the large-area compression of the end walls is more conducive to the uniform distribution of powder in the powder layer, so as to form a more uniform thickness distribution.

[0057] In addition, the two side walls of the feeding section 16 are arranged in parallel, which can constrain the powder on the side of the powder layer and prevent the powder from spreading or deforming laterally during the conveying process, so that the powder layer is formed with uniform thickness at both the feeding section 16 and the outlet of the feeding section 16.

[0058] Furthermore, the feeding section 15 is provided with a feeding screw 17, which is used to push the powder towards the feeding section 16 during rotation.

[0059] Specifically, the feeding screw 17 extends along the conveying direction of the powder material; the drive motor of the feeding screw 17 is started, causing the feeding screw 17 to start rotating, and its spiral blades will continuously push the powder material from the inlet end of the feed section 15 to the feeding section 16. During this process, the powder material will be subjected to the squeezing and shearing action of the spiral blades, which helps to expel the air inside and make the powder more compact.

[0060] Meanwhile, when the powder layer reaches the outlet of the feeding section 16, the continuous rotation of the feeding screw 17 and the powder layer's own gravity provide a continuous driving force for the powder layer, enabling the powder layer to smoothly enter the compaction space 23 and complete the compaction process.

[0061] 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 disposed on both sides of the feeding section 15, and a material dropping interval is formed between the two first baffles 18; the two second baffles 19 are respectively disposed 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 material dropping interval.

[0062] Based on this structure, the transition interval and the discharge interval are connected; when conveying powder material, the powder material in the feed section 15 enters the feeding section 16 with the width of the drop interval, then enters the guide section with the width of the transition interval, and finally enters the compaction space 23 with the width of the discharge interval.

[0063] The feeding screw 17 is located in the middle of the feeding section 15. Therefore, the moving speed of the powder material in the middle of the feeding section 15 is greater than that of the powder material on both sides of the feeding section 15. In this embodiment, by setting a smaller drop interval between the two first baffles 18, the powder material is more concentrated in the middle of the feeding section 15. The powder material can enter the feeding section 16 more under the push of the feeding screw 17, reducing the residence 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.

[0064] In addition, the transition interval serves as a buffer zone for the powder material from the feed section 15 to the guide section, ensuring a smooth transition of the powder and preventing accumulation or blockage during the conversion process.

[0065] Furthermore, the widths of both the material dropping interval and the transition interval are adjustable.

[0066] Therefore, the material drop interval between the two first baffles 18 can be manually adjusted first, and then a guide section with a suitable height of guide channel 14 can be selected and connected to hopper 1. Then, the position of the width adjustment plate 32 in the guide section can be adjusted by a drive component (such as a cylinder) to adjust the discharge interval. Then, the transition interval between the two second baffles 19 can be adjusted by another drive component (such as a cylinder) so that the material drop interval and the discharge interval can be connected by the transition interval.

[0067] The width of the discharge interval needs to be adjusted according to the width of the brick blank 5 to be pressed and formed. The width of the drop interval can be adjusted according to the amount of powder to be conveyed. The width of the drop interval is set to be smaller than the width of the discharge interval. The width of the transition interval is between the discharge interval and the drop width.

[0068] In addition, one end of the width adjustment plate 32 can be detachably connected to one end of the second baffle 19. In this way, when the transition interval between the two second baffles 19 is adjusted by the driving component, the width adjustment plate 32 can be moved together to adjust the material dropping interval.

[0069] Furthermore, the feeding assembly includes a first driving member, and the power output end of the first driving member is connected to the second baffle 19, wherein the first driving member is used to drive the two second baffles 19 to move closer to each other or further away from each other.

[0070] Specifically, the first driving component can be a combination of an electric push rod, a cylinder, a servo motor, and a ball screw; by driving the two second baffles 19 to move closer or further apart, the width of the transition interval can be reduced or increased. In this way, the hopper can discharge powder layers of different widths and uniform thicknesses at the outlet.

[0071] Further, see Figure 1 The brick-making equipment includes a receiving device 4. Specifically, the receiving device 4 includes an active rotating component, a passive rotating component, and a conveyor belt. The conveyor belt surrounds the active rotating component and the passive rotating component. The active rotating component is used to drive the conveyor belt to rotate, and the conveyor belt is used to receive the brick blanks 5 sent out from the compaction space 23.

[0072] Based on this structure, after the compaction space 23 completes the pressing of the brick blank 5, the receiving device 4 begins to operate. First, the active rotating component (such as a motor-driven roller) is activated, driving the conveyor belt to rotate through friction. The brick blank 5 enters the receiving end of the transmission belt under the push of the forming roller assembly 2. As the conveyor belt rotates continuously, it transfers the received brick blank 5 to the next process.

[0073] The speed and direction of the conveyor belt can be adjusted by changing the rotation speed and direction of the active rotating component, thereby meeting different production needs.

[0074] Furthermore, the receiving device 4 can also be a form in which multiple conveying rollers convey the material. Specifically, multiple conveying rollers are arranged at the outlet of the compaction space 23, and all multiple conveying rollers rotate synchronously in the same direction. The brick blank 5 is discharged from the compaction space 23 and received by the conveying rollers, which output the brick blank 5 during rotation. It is understood that the receiving device 4 can also be other transmission structures in the prior art.

[0075] In summary, this application directly outputs a uniformly thick powder layer through hopper 1, which is vertically oriented, eliminating the need for the feeding conveyor belt commonly used in traditional brick-making equipment. This reduces equipment maintenance costs and improves equipment reliability and stability. Furthermore, the horizontal volume occupied by the brick-making equipment in this application is significantly reduced, making the overall device more compact and smaller.

[0076] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
