[0028] 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 herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] The embodiment of the utility model discloses a roller pressing device, which is used for compacting powder 6 into a brick blank 8.

[0030] See also Figure 2-Figure 4 The roller pressing device includes a conveying assembly, which may specifically include a conveyor belt 11 for conveying the powder 6 along a conveying direction, such as direction A in the figure.

[0031] The roller pressing device also includes a hopper 2, which is provided with a discharge port 21 for placing the powder 6 on the conveyor belt 11. For example, the hopper 2 can be specifically arranged above the conveyor belt 11, and the powder 6 will fall onto the conveyor belt 11 due to gravity; the hopper 2 is also provided with a baffle 5, which is arranged on the opposite side of the discharge port 21 and the conveying direction of the powder 6.

[0032] The roller pressing device also includes a side guard assembly, which is arranged above the conveyor belt 11. The side guard assembly has two side guard strips 31. The two side guard strips 31 extend to the discharge port 21 of the hopper 2 and are constrained together with the baffle 5 to form a conveying area.

[0033] In the specific implementation, the roller pressing device specifically extends the conveying area to the bottom of the discharge port 21 of the hopper 2, so the powder 6 will fall directly from the discharge port 21 of the hopper 2 into the conveying area, and the powder 6 can be well shaped, that is, the two sides of the powder 6 will not form a freely collapsed repose angle 61, so that the collapsed positions of the two edges of the powder 6 have the same thickness and density as the middle position. At the same time, the baffle 5 is used to limit the powder 6 from collapsing on the side of the hopper 2 away from the conveying direction, thereby ensuring that the powder 6 has a stable flow state and the quality of the laying of the powder 6. In summary, the powder 6 is directly laid from the hopper 2 through the discharge port to the range constrained by the baffle bar. Constrained by the baffle bar, the two edges of the powder 6 will not collapse, and the thickness and density of the powder 6 at each position are consistent. Under the constraint of the baffle bar, the powder 6 is compacted into a brick 8 through the conveyor belt 11, which can better press the powder 6, improve the quality of the brick 8, and reduce waste.

[0034] In an optional embodiment, the conveying area can specifically extend to directly below the discharge port 21 of the hopper 2. Not only will the powder 6 fall directly from the discharge port 21 of the hopper 2 into the conveying area, the powder 6 can be well shaped, and the structure will also be more compact.

[0035] In an optional embodiment, a sidewall strip 31 is provided with a clearance notch 311 for adapting to the scraper strip 22 in the material discharge port of the hopper 2 at one end thereof close to the hopper 2. Since the material discharge port of the hopper 2 is provided with a scraper strip 22, in order to avoid interference between the scraper strip 22 and the sidewall strip 31, a clearance notch 311 is provided on the sidewall strip 31, which can well avoid the position of the scraper strip 22 to avoid interference and ensure the operational stability of the roller press device. Optionally, the shape of the clearance notch 311 can also adapt to the shape of the scraper strip 22 in the material discharge port of the hopper 2, so that there will be no leakage.

[0036] It should be noted that the scraper strip 22 has two main functions: thickness setting and leveling. The thickness of the powder 6 conveyed on the conveyor belt 11 is determined by the gap between the scraper strip 22 and the conveyor belt 11, and this gap can be adjusted according to actual conditions. The surface of the pressed powder 6 needs to be flat, and usually the hopper 2 is equipped with a scraper strip 22 to level the powder 6.

[0037] Optionally, the scraper bar 22 and the baffle 5 can be arranged at the bottom of the hopper 2 to form a discharge port 21 between the scraper bar 22 and the baffle 5, which can better restrict the discharge direction of the powder 6 and has a simple structure, which is easy to manufacture and reduces the manufacturing difficulty.

[0038] Optionally, the avoidance notch 311 may be specifically provided on the upper end surface of the sidewall strip 31 facing the hopper 2 to better prevent interference with the hopper 2 .

[0039] In an optional embodiment, the sidewall assembly includes two sidewall adjustment devices 32, one sidewall adjustment device 32 is fixedly connected to a sidewall strip 31, and is used to adjust the two sidewall strips 31 to move closer to or farther from each other. Since in the actual manufacturing process of pressing the powder 6, it is necessary to press and form brick blanks 8 with different width requirements, in order to improve the efficiency of pressing and converting brick blanks 8 with different widths, by setting the sidewall adjustment device 32, it can be specifically used to adjust the two sidewall strips 31 to move closer to or farther from each other, and the width between the two sidewall strips 31 can be adjusted as needed, thereby achieving the pressing requirements of brick blanks 8 with different widths.

[0040] Optionally, the side guard adjusting device 32 is arranged on the outer side of the side guard strip 31 facing away from the conveying area, which can effectively avoid the interference of the side guard adjusting device 32 with the conveying area and improve the safety of the whole machine.

[0041] Optionally, the sidewall adjusting device 32 may be specifically a telescopic cylinder or a telescopic motor, which has a simple structure, is easy to manufacture, and reduces the manufacturing difficulty.

[0042] In an optional embodiment, the roller pressing device further includes a pressing assembly, which includes an upper forming roller 41 and a lower forming roller 42, the upper forming roller 41 and the lower forming roller 42 are spaced apart in the vertical direction, and the upper forming roller 41 and the lower forming roller 42 jointly form a compacting space, which is used to receive the powder 6 on the conveyor belt 11 and compact the powder 6 to form a brick 8. In this way, the pressing assembly is used to press the powder 6 on the conveyor belt 11 to form a brick 8. Of course, in other embodiments, the pressing assembly can also be other pressing roller structures to press the powder 6.

[0043] Optionally, in the conveying direction of the conveyor belt 11, one end of the two sidewall strips 31 is connected to the compacting space and the other end extends to the discharge port 21 of the hopper 2. In this way, the powder 6 will fall directly from the discharge port 21 of the hopper 2 into the conveying area, and the powder 6 can be well shaped, that is, the two sides of the powder 6 will not form a freely collapsed repose angle 61, so that the collapsed positions of the two edges of the powder 6 have the same thickness and density as the middle position, and then will be directly sent to the compacting space for compaction to be formed into a brick 8.

[0044] In an optional embodiment, the edge strip 31 is arranged in an arc transition at one end close to the upper forming roller 41 to adapt to the curvature of the upper forming roller 41. Such arrangement can effectively avoid interference between the edge strip 31 and the upper forming roller 41, thereby improving the safety of the whole machine.

[0045] In an optional embodiment, the sidewall assembly includes two sidewall pushing devices 33, one sidewall pushing device 33 is in contact with one of the sidewall strips 31, and the sidewall pushing device 33 is arranged at one end of the sidewall strip 31 close to the upper forming roller 41. Such arrangement can provide sufficient force during the pressing process to avoid deformation or displacement of the sidewall strip 31, ensure the uniform forming width of the powder 6, and further improve the quality of the brick 8.

[0046] It should be noted that the sidewall pushing device 33 is in contact with the material retaining strip and is not fixedly connected to facilitate quicker adjustment.

[0047] Optionally, the sidewall pushing device 33 is arranged on the outer side of the sidewall strip 31 facing away from the conveying area. Such arrangement can effectively avoid the interference of the sidewall pushing device 33 with the conveying area and improve the safety of the whole machine.

[0048] Optionally, the sidewall pushing device 33 may be specifically a telescopic cylinder or a telescopic motor, which has a simple structure, is easy to manufacture and produce, and reduces the difficulty of manufacturing.

[0049] In an optional embodiment, the pressing assembly includes an upper active roller 43, an upper driven roller 44, and a compacting belt 45 tensioned between the upper active roller 43 and the upper driven roller 44, and the upper forming roller 41 is arranged between the upper active roller 43 and the upper driven roller 44. In this arrangement, the powder 6 can be pressed by using the upper forming roller 41, the compacting belt 45, the conveyor belt 11 and the lower forming roller 42.

[0050] In an optional embodiment, the conveying assembly includes a lower active roller 12, a lower driven roller 13, and a conveyor belt 11 stretched between the lower active roller 12 and the lower driven roller 13, and the lower forming roller 42 is arranged between the lower active roller 12 and the lower driven roller 13. The transmission of the conveyor belt 11 can be specifically used to convey the powder 6. Of course, in other embodiments, the conveying assembly can also be specifically a belt conveyor for conveying materials.

[0051] In an optional embodiment, in the height direction of the sidewall strip 31, the upper end surface of the baffle 5 is flush with or protrudes from the upper end surface of the sidewall strip 31. In this arrangement, it is found in actual use that after the powder 6 falls into the conveying area, the powder 6 will collapse to the rear side of the conveying area and collapse beyond the conveying area formed by the two sidewall strips 31. Therefore, by setting the baffle 5 to prevent the powder 6 from collapsing to the rear side, it can further ensure that different positions of the powder 6 have the same thickness and density, thereby improving the quality of the brick 8.

[0052] In an optional embodiment, the rolling device also includes a limit plate 71 and a driving device 72 for driving the limit plate 71 to rise and fall in the vertical direction. The upper driven roller 44, the upper forming roller 41, the limit plate 71 and the upper active roller 43 are arranged in sequence in the conveying direction. The limit plate 71 can be specifically utilized to gradually release the internal stress of the compacted brick blank 8 to improve the quality of the brick blank 8.

[0053] Optionally, the driving device 72 can be specifically a telescopic cylinder or a telescopic motor, which has a simple structure, is easy to manufacture and produce, and reduces the difficulty of manufacturing.

[0054] In summary, in the prior art, when the hopper 2 arranges the powder 6 on the conveyor belt 11, the powder 6 is in a free accumulation state, and a freely collapsed repose angle 61 will be formed on both sides of the powder 6. Therefore, in order to make the powder 6 have the same thickness and density when compacted, the powder 6 needs to be processed before compaction so that the collapsed positions at the two edges of the powder 6 have the same thickness and density as the middle position. In order to achieve this effect, the roller pressing device extends the retaining bar directly to the bottom of the discharge port of the hopper 2, and the powder 6 is directly arranged from the hopper 2 through the discharge port to the range constrained by the retaining bar. Constrained by the retaining bar, the two edges of the powder 6 will not collapse, and the thickness and density of the powder 6 at each position are consistent. Then, under the constraint of the retaining bar, the powder 6 is transported through the conveyor belt 11 into the compaction space formed by the upper forming roller 41 and the lower forming roller 42, and compacted into a brick blank 8, which can better press the powder 6 and improve the quality of the brick blank 8.
