Description

TECHNICAL FIELD

[0001] The present application relates to the field of building technology, in particular to a brick making equipment and method capable of trimming powder edges. BACKGROUND

[0002] At present, the cross section of the powder material layer laid by the material distribution device is usually trapezoidal with flat middle and sunken sides, so the uniformity of the whole powder material layer in the width direction is poor; after pressing, the density of the formed green brick is uneven and the quality cannot meet the standard requirements.

[0003] In order to trim the edges of the powder material layer before pressing into green bricks, a wider powder material layer is usually laid first, and then a cutting device is arranged to cut the powder material delivered at a certain distance from the edge to remove the irregular edge powder material, and then the outer powder material is collected. This method wastes a lot of powder material and cannot control the shape of the edge material to adjust the density of the edge area of the formed green brick.

[0004] During pressing, the powder material layer may also spread outward on both sides during pressing, resulting in uneven internal density of the final pressed green brick; there is also a method of pouring the powder material into the mold, piling it up and then pressing it into shape. However, this pressing method requires different molds when pressing different sizes of green bricks, and the pressing surface of the pressing device also needs to be adjusted accordingly, which is more troublesome to operate.

[0005] In order to ensure that the pressed green brick has uniform density, there is an urgent need for a brick making equipment and method capable of trimming powder edges. SUMMARY

[0006] In order to overcome the shortcomings of the prior art, the purpose of the present application is to provide a brick making equipment and method capable of trimming powder edges to achieve trimming of the edges of the powder material layer for pressing and forming.

[0037] 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 the present application belongs. The terminology used in the specification of the present application herein is only for the purpose of describing specific embodiments and is not intended to limit the present application.

[0038] Referring to Figure 1 and Figure 2 The embodiment discloses a brick making equipment capable of trimming powder edges, comprising a conveying assembly, a stacking assembly 3 and an adjusting assembly 4, the conveying assembly is used for conveying a powder material layer 201 along a conveying direction, the stacking assembly 3 and the adjusting assembly 4 are arranged along the conveying direction in sequence;

[0039] The pile assembly 3 is used to trim the lateral edge of the powder material layer 201, and the conveying assembly is provided with the pile assembly 3 on both sides. According to the actual application, the pile assembly 3 can be provided with two, and the two pile assemblies 3 are respectively arranged on both sides of the conveying assembly, and the two pile assemblies 3 are spaced apart to form a pile spacing, and the powder material layer 201 is conveyed to the pile spacing for trimming work.

[0040] The pile assembly 3 comprises a pile block 301, which is installed on the conveying assembly, and is used to pile the powder on the edge of the powder material layer 201 to the middle, so as to trim the edge of the powder material layer 201 in the pile spacing;

[0041] The adjusting assembly 4 is used to adjust the position of the pile block 301 and laterally constrain the powder material layer 201 with trimmed edges, and the adjusting assembly 4 comprises a baffle strip 405, which is arranged on both sides of the conveying assembly. According to the actual application, the baffle strip 405 can be provided with two, and the two baffle strips 405 are respectively arranged on both sides of the conveying assembly; the two baffle strips 405 are spaced apart to form a conveying spacing, and the conveying spacing is through the pile spacing. After the powder material layer 201 is trimmed in the pile spacing, it is transported to the conveying spacing, and the baffle strip 405 is used to block the powder material layer 201 in the lateral position of the conveying spacing.

[0042] On the basis of the structure, the brick making equipment with trimmable powder edges of the embodiment is used to fill the powder material into the distribution assembly 1, refer to Figure 7 and Figure 8 , the powder is arranged to fall from the distribution assembly 1 to the conveying assembly to form a powder material layer 201 with a width of W1 and a reduced thickness on both sides, and then is transported by the conveying assembly to the pile spacing along the conveying direction, and the reduced thickness on both sides of the powder material layer 201 is trimmed by the pile assembly 3 on both sides of the pile spacing, so that the powder material layer 201 with a uniform thickness and a width of W2 is formed, and the width W2 is less than the width W1.

[0043] The conveying assembly transports the powder material layer 201 with trimmed edges to the conveying spacing, the conveying spacing is adjusted to have a spacing width of W2, and the powder material layer 201 on both sides is constrained and shaped by the baffle strip 405 on both sides of the conveying spacing to prevent the edge powder from being scattered again; finally, the conveying assembly transports the powder material layer 201 to the compaction assembly, and the powder material layer 201 is compacted by the compression roller assembly under the blocking of the baffle strip 405 on both sides to form a brick blank 202 with a width of W2.

[0044] The distribution assembly 1 can be a distribution box in the prior art, which is installed above the conveying assembly and uniformly distributes the powder downward at a constant speed. The distribution box can arrange the powder material layer 201 with a width of W1 according to the width W2 of the brick blank 202 to be made, and W1 is greater than W2.

[0045] Further, since the stack block 301 is placed obliquely relative to the edge of the powder material layer 201, the stack block 301 forms an angle θ with the powder material layer 201.

[0046] Before the powder material layer 201 with a width of W1 is trimmed, the width between the stack blocks on both sides of the conveying assembly can be adjusted, and then the angle θ of the stack block relative to the edge of the powder material layer can be adjusted.

[0047] Referring to Figure 5 In order to better adjust the angle θ of the stack block 301 and the powder material layer 201, a rotating shaft 303 can be installed on the stack block 301. Specifically, a first mounting hole is arranged on the stack block, a base is arranged on the rotating shaft, a second mounting hole is arranged on the base, the first mounting hole and the second mounting hole are arranged correspondingly, and a screw member is sequentially locked into the first mounting hole and the second mounting hole to fixedly connect the rotating shaft to the stack block.

[0048] In this way, the stack block can be rotated by rotating the rotating shaft, so that part of the stack block 301 is located in the edge of the powder material layer 201. When the powder material layer 201 is conveyed, the stack block 301 piles up the powder with a relatively thin thickness at the edge of the powder material layer 201 to the middle, so that the width of the powder material layer 201 gradually decreases from W1 to W2 after the edge is trimmed by the stack block 301, so as to adjust the thickness of the powder at the edge to be the same as the thickness of the powder in the middle.

[0049] Further, the adjusting assembly 4 is arranged along the conveying direction and sequentially arranged after the stack assembly 3. The adjusting assembly 4 comprises a blocking strip 405, and the blocking strip 405 is arranged on both sides of the conveying assembly. The blocking strip 405 on both sides of the conveying assembly is spaced apart to form a conveying interval, and the conveying interval is in communication with the stack interval. The blocking strip 405 is used to receive the powder material layer 201 with a trimmed edge and to block the powder material layer 201 at the lateral position of the conveying interval.

[0050] On the basis of the above structure, the powder material layer 201 is first trimmed at the edge in the stack interval, and then received by the blocking strip 405 and conveyed to the conveying interval. Under the lateral constraint of the blocking strip 405, the powder at the lateral edge does not sink during the conveying process, and the overall thickness of the powder material layer 201 remains unchanged.

[0051] The blocking strip 405 is arranged at the end of the stack assembly 3 and connected to the stack block 301, which can prevent the powder from scattering during transportation after trimming. In order to fix the blocking strip 405 at the end of the stack assembly 3, a fixed rod 401 can be arranged, which spans the conveying interval, and the two sides of the fixed rod 401 are respectively installed on both sides of the conveying assembly through a bolt member.

[0052] The two sides of the fixed rod 401 are fixedly connected with connecting plates 404, one end of the connecting plate 404 is connected with the fixed rod 401 through a screw, and the other end of the connecting plate 404 is connected with the baffle strip 405 through a screw, and the baffle strip 405 is parallel to the conveying direction of the conveying assembly.

[0053] Since the fixed rod 401 is fixedly connected on the two sides of the conveying assembly, and the baffle strip 405 is fixedly connected with the fixed rod 401, the baffle strip 405 can overcome the friction force caused by the movement of the conveying assembly, so as to be fixedly arranged at the end of the stacking interval, for receiving the powder material layer 201 conveyed by the stacking interval, and blocking the powder material layer 201 in the conveying interval from the lateral position.

[0054] By adjusting the stacking block 301, the edge of the powder material layer 201 can be trimmed, the powder at the edge is gathered to the middle, and the sunken edge on both sides is eliminated; and then the baffle strip 405 blocks the powder from the lateral position of the powder material layer 201, so as to prevent the powder on both sides from diffusing again before being transported to the next processing station.

[0055] Further, the baffle strips 405 on the two sides of the conveying assembly can move close to each other or move away from each other, so as to control the width of the conveying interval.

[0056] In order to enable the baffle strips 405 on the two sides of the conveying assembly to move close to each other or move away from each other, further, the adjusting assembly 4 comprises a fixed rod 401 and a sliding block 403, the two ends of the fixed rod 401 are fixed on the two sides of the conveying assembly, the fixed rod 401 has a guide rail 402, and the sliding block 403 is slidably connected to the guide rail 402, and the sliding block 403 is connected with the baffle strip 405.

[0057] On the basis of the structure, the fixed rod 401 and the guide rail 402 can be integrally arranged, the guide rail 402 can be arranged as a convex rail, one side of the sliding block 403 is provided with a groove, and the groove is slidably connected to the convex rail from one end of the convex rail; in this way, the sliding block 403 can slide on the guide rail 402, and the baffle strips 405 on the two sides of the fixed rod 401 can be driven by the sliding block 403 to move close to each other or move away from each other.

[0058] Specifically, according to the actual use, the number of the baffle strips 405 can be set to two; in this way, the two baffle strips 405 are arranged on the two sides of the conveying assembly. In order to enable the baffle strips 405 on the two sides of the conveying assembly to move close to each other or move away from each other, the number of the sliding blocks 403 can also be set to two, the two sliding blocks 403 are slidably connected to the guide rail 402, and the two baffle strips 405 on the two sides of the conveying assembly are connected with the two sliding blocks 403.

[0059] In this way, the slider 403 can drive the baffle strip 405 to move; specifically, since the slider 403 and the baffle strip 405 are arranged in sequence in the vertical direction, the lower end of the slider 403 can be extended to the upper end of the baffle strip 405, and then the two are connected by the bolt.

[0060] In this way, when the two sliders 403 slide on the guide rail 402 to move closer to each other or move away from each other, the two sliders 403 can drive the two baffle strips 405 to move closer to each other or move away from each other, so as to adjust the width W2 of the conveying interval, that is, the width W2 of the green brick 202 to be manufactured can be used to adjust the width of the conveying interval to W2, that is, the two baffle strips 405 are moved, so as to manufacture green bricks 202 of different sizes;

[0061] In addition, the baffle strips on both sides of the conveying assembly can be provided in multiple numbers, and the multiple baffle strips on each side are connected in sequence and extend to the end of the conveying assembly, so as to laterally block the powder material layer during the transportation of the powder material layer with the edges trimmed.

[0062] Further, in order to enable the stacking blocks on both sides of the conveying assembly to move closer to each other so as to adjust the width of the stacking interval, the adjusting assembly 4 further comprises a connecting plate 407, one end of the connecting plate 407 being connected with the slider 403, and the other end of the connecting plate 407 being connected with the stacking block 301.

[0063] On the basis of the above structure, when the slider 403 adjusts the width between the baffle strips on both sides of the conveying interval, since the slider is connected with the connecting plate, and the connecting plate is connected with the stacking block, the slider 403 will also drive the stacking blocks on both sides of the conveying interval to move closer to each other or move away from each other, so as to adjust the width of the stacking interval.

[0064] At this time, since the slider 403 and the baffle strip 405 are arranged in sequence in the vertical direction, and a connecting piece 404 is provided, one end of the connecting piece 404 is connected with the slider 403 above through a screw, and the other end of the connecting piece 404 is connected with the baffle strip 405 below the slider 403 through a screw.

[0065] In this way, when the slider 403 slides on the guide rail 402, the slider 403 can drive the baffle strips 405 on both sides of the conveying assembly to move closer to each other or move away from each other on the conveying assembly, so as to adjust the width of the conveying interval.

[0066] In addition, since one end of the connecting plate 407 and one end of the connecting piece 404 are connected with the slider 403, the connecting position of the connecting plate 407 and the slider 403 and the connecting position of the connecting piece 404 and the slider 403 overlap, that is, the slider 403 drives the baffle strip 405 and the stacking block 301 to move at the same time.

[0067] Specifically, both ends of the connecting plate are provided with third mounting holes, both ends of the connecting piece are provided with fourth mounting holes, the third mounting hole of the connecting plate near the slider is placed coincident with the fourth mounting hole of the connecting piece near the slider, and the third mounting hole and the fourth mounting hole are sequentially connected on the slider through the bolt piece.

[0068] The third mounting hole of the connecting plate near the stacking block is connected with the rotating shaft of the slider.

[0069] In addition, the stacking block 301 and the baffle strip 405 are also subjected to the pulling force of the fixing rod 401 through the slider 403, so that the stacking block 301 and the baffle strip 405 do not move together with the conveying assembly, thereby being able to adjust work on the respective workstations.

[0070] Furthermore, the baffle strips 405 on both sides move close to or away from each other on the conveying assembly, so that the conveying interval is adjustable in width, that is, after the width of the green brick 202 to be manufactured is determined, the position of the slider 403 is adjusted, the slider 403 drives the stacking block 301 and the baffle strip 405 on both sides of the conveying assembly to move close to or away from each other, thereby adjusting the width of the stacking interval and the conveying interval.

[0071] Then, by rotating the rotating shaft of the stacking block 301, the amount of powder entering the baffle strip 405 is controlled, so that powder material layers 201 of different widths can be obtained, and thus green bricks 202 of different widths can be manufactured after the powder material layers 201 are compacted.

[0072] In addition, in order to prevent the baffle strip 405 from moving in the conveying direction and enabling the baffle strip 405 to move close to or away from each other in the direction perpendicular to the conveying direction, the baffle strip 405 can also be driven by a pneumatic cylinder.

[0073] Specifically, a pneumatic cylinder can be arranged on each side of the conveying assembly, and the piston rod of the pneumatic cylinder is fixedly connected to the side of the baffle strip 405 away from the powder feeding surface, so that the baffle strip 405 is fixedly connected to the piston rod of the pneumatic cylinder and cannot move in the conveying direction, while the piston rod can move forward and backward relative to the pneumatic cylinder, thereby driving the baffle strip 405 to move in the direction perpendicular to the conveying direction, so that the baffle strips 405 on both sides of the conveying assembly can move close to or away from each other.

[0074] Further, referring to Figure 4 , the adjusting assembly 4 further comprises a baffle plate 406, one end of the baffle plate 406 is connected to the baffle strip 405, and the other end of the baffle plate 406 is used to abut against the end of the stacking block 301 close to the baffle strip 405.

[0075] On the basis of the structure, the baffle 406 is reliably arranged on the side of the baffle strip 405 facing the conveying assembly, and the baffle 406 protrudes from one end of the baffle strip 405. The baffle 406 can be fixedly connected with the baffle strip 405 through a screw member.

[0076] Since the stacking block 301 and the baffle strip 405 are linked through the sliding block 403, the interval width between the stacking block 301 and the baffle strip 405 on both sides of the conveying assembly can be first adjusted through the sliding block. The width between the stacking block 301 on both sides and the width between the baffle strip 405 on both sides are both adjusted to W2. Then, the included angle of the stacking block 301 relative to the edge of the powder material layer is adjusted.

[0077] At this time, since the stacking block 301 rotates relatively, there is a gap between the stacking block 301 and the baffle strip 405 in the conveying direction and the width direction. At this time, the third mounting hole on the connecting plate 407 can be set as an oblong hole. Specifically, the length direction of the oblong hole close to the one end of the stacking block is set along the conveying direction, and the length direction of the oblong hole close to the one end of the sliding block is set along the width direction of the conveying assembly.

[0078] In this way, the stacking block 301 can move in the conveying direction through the oblong mounting hole, and can move in the width direction without driving the sliding block to move, so as to move the stacking block 301 close to the baffle.

[0079] Thus, the end surface of the baffle 406 is in close contact with the stacking block 301. In this way, there is no gap between the stacking block and the baffle strip, so as to prevent the powder material from overflowing from the gap.

[0080] Further, the conveying end of the conveying assembly is provided with a compaction device 5 for discharging the powder material layer 201 with a trimmed edge after compaction and forming. The compaction device 5 includes a compression roller assembly including a first compression roller 501 and a second compression roller 503. The first compression roller 501 and the second compression roller 503 are spaced apart in the vertical direction and form a compaction space. The compaction space is in communication with the conveying interval and is used to receive the powder material layer 201 conveyed by the conveying interval.

[0081] On the basis of the structure, the conveying assembly conveys the powder material layer 201 with a trimmed edge into the compaction space. A pressing oil cylinder 703 can be arranged above the first compression roller 501. Specifically, the piston rod of the pressing oil cylinder 703 is connected with the first compression roller 501. The pressing oil cylinder 703 drives the first compression roller 501 to press downward, and the first compression roller 501 and the second compression roller 503 jointly apply a pressing force to make the powder material layer 201 compacted and formed.

[0082] In addition, the first compression roller 501 driven by the pressing oil cylinder 703 can be adjusted in height according to the thickness of the green brick 202 to be produced, so as to press the green brick 202 meeting the thickness requirement.

[0083] It should be noted that in the embodiment, the conveying assembly includes the conveying belt 504, a driving wheel and a driven wheel, the driving wheel can be the second discharging roller 506, and the driven wheel can be the second driven roller 508.

[0084] The conveying assembly is connected by the conveying belt 504 surrounding the second discharging roller 506 and the second driven roller 508, the second discharging roller 506 is connected with the second motor 702, the second motor 702 drives the second discharging roller 506 to rotate, thereby driving the conveying belt 504 to rotate, the second driven roller 508 rotates synchronously with the second discharging roller 506 under the action of the conveying belt 504, and the conveying belt 504 rotates stably.

[0085] On the basis of the structure, the second compression roller 503 is arranged between the second discharging roller 506 and the second driven roller 508, the second compression roller 503 rotates synchronously with the second discharging roller 506 under the action of the conveying belt 504, and the second compression roller 503 also forms a support surface and a conveying surface of the powder material layer 201 during compression together with the conveying belt 504.

[0086] Further, the baffle strips 405 are movably arranged at two sides of the compacting space, and the baffle strips 405 extend to the end of the compacting space along the conveying direction.

[0087] On the basis of the structure, the baffle strip 405 is a baffle strip 405 with a fiber fabric as a skeleton layer and a nitrile rubber layer adhered to the upper and lower surfaces of the fiber fabric, and the baffle strip 405 has a certain elasticity; since the baffle strip 405 has a certain length, in order to enable the baffle strip 405 to be parallel to the conveying direction, a set of the adjusting assembly 4 described above can be arranged at the end of the compacting space, and the two sides of the adjusting assembly 4 are connected with the ends of the baffle strips 405 at the two sides, respectively.

[0088] In this way, according to the width of the green brick 202 to be produced, the front and rear adjusting assemblies 4 are synchronously adjusted, the powder material layer 201 is conveyed to the compacting space for compression under the limitation of the lateral position of the baffle strips 405 after the conveying interval meeting the width requirement is obtained, and the width of the green brick 202 to be produced is obtained. Figure 6 Since the baffle strip 405 is a flexible material with elasticity, the baffle strip 405 can better fit on the conveying assembly during compression of the compression roller assembly, thereby preventing the powder material layer 201 from spreading apart from the lower side gap of the baffle strip 405.
