Detailed implementation manners
[0025] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the attached drawings in the embodiments of the present invention.
[0026] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the attached drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.
[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0028] The present invention will be further described in detail below with reference to the attached drawings.
[0029] Please refer to Figure 1 , which is a schematic structural view of a material tape formed by a powder processing device for laying powder in the prior art. Since the hardness of the powder is relatively low and it is in a free state, the angle of repose α of collapse will appear on both sides in the width direction of the powder, thus affecting the thickness and compactness of the subsequent compaction into a brick blank and the quality of the brick blank.
[0030] Please refer to Figures 2 to 6 , which is a powder processing device 100 provided by an embodiment of the present invention, including a conveying mechanism 10, a feed hopper 20, a retaining bar 30, and a replenishing mechanism 40.
[0031] Among them, the conveying mechanism 10 is used to convey the powder material and form a material belt 200 on the conveying mechanism 10; the feeding hopper 20 is used to feed the powder material into the conveying mechanism 10; there are two retaining bars 30, and the two retaining bars 30 are arranged on both sides in the width direction of the conveying mechanism 10 for constraining the powder material; there are two feeding mechanisms 40, and the two feeding mechanisms 40 are arranged at the front ends of the retaining bars 30 and on both sides in the width direction of the conveying mechanism 10 for feeding the powder material to both sides in the width direction of the material belt 200.
[0032] For the above powder material processing device 100, the powder material is fed through the feeding hopper 20, and the powder material is received by the conveying mechanism 10 so that the powder material gradually forms a material belt 200. Further, two feeding mechanisms 40 are arranged on both sides in the width direction of the conveying mechanism 10 and at the front ends of the retaining bars 30. The powder material is constrained by the retaining bars 30, and the two feeding mechanisms 40 feed both side edges in the width direction of the material belt 200, avoiding the situation of collapse on both sides of the material belt 200, making the material belt 200 have the same thickness and density in the width direction, and improving the forming quality of the subsequent roll pressing of the material belt 200 into the brick blank 300.
[0033] Among them, in this embodiment, the schematic structural diagram of the formed material belt 200 is as Figure 6 shown. The feeding mechanism 40 is arranged at the front end in the conveying direction of the conveying mechanism 10, so that both sides in the width direction of the material belt 200 can be fed by the feeding mechanism 40 when the feeding hopper 20 starts to feed, thus ensuring the equal density and equal thickness effect during the subsequent compaction of the entire material belt 200.
[0034] Specifically, please refer to Figure 4 and Figure 5 , the feeding mechanism 40 includes a feeding hopper 41 and a feeding cylinder 42 arranged at the bottom of the feeding hopper 41. The feeding cylinder 42 and the feeding hopper 41 are detachably connected. In this way, the divided material is gradually leaked through the feeding hopper 41 and leaked to the conveying mechanism 10 through the feeding cylinder 42. At the same time, by the way of detachably installing the feeding cylinder 42, the feeding cylinder 42 can be disassembled and replaced according to the required thickness of the material belt 200, and the height of the feeding cylinder 42 can be adjusted to adapt to the thickness of the material belt 200.
[0035] Specifically, the feeding cylinder 42 and the feeding hopper 41 of this embodiment are connected by means of threads, so as to ensure the stability of the installation. In other embodiments, they can also be connected by means of clamping, plugging, etc.
[0036] Further, when the feeding cylinder 42 is arranged in this embodiment, the bottom of the feeding cylinder 42 is set to be flush with the surface of the material belt 200. Thus, when the powder material gradually flows out from the feeding cylinder 42, the bottom of the feeding cylinder 42 can level the powder material to avoid excessive accumulation of the powder material, thereby ensuring the consistency of the thickness of the material belt 200.
[0037] Further, in order to ensure the fabric effect, the bottom of the replenishing hopper 42 is at least flush with the side of the tape 200 along its width direction, or partially located on the upper surface of the tape 200. In this way, when it is flush with the side along its width direction, the powder just falls into the area corresponding to the collapse angle α; when it is partially located on the upper surface of the tape 200, part of the powder falls into the area corresponding to the collapse angle α, and part falls on the upper surface of the tape 200 and is leveled by the replenishing hopper 42.
[0038] Among them, in this embodiment, under the action of the retaining bar 30, the powder is constrained. When the powder gradually leaks from the feed hopper 20, it is gradually conveyed by the conveying mechanism 10 to form a tape 200. Under the constraint of the retaining bar 30, a tape 200 with a preset width is formed. Please refer to Figure 5 , when setting the retaining bar 30, the width L2 between the two retaining bars ≥ the width L1 of the tape, that is, the width between the two retaining bars 30 can just form the width of the tape 200. At this time, the width between the two retaining bars 30 is equal to the feeding width of the feed hopper 20, or the width between the two retaining bars 30 can be greater than the feeding width of the feed hopper 20. At this time, the width L1 of the tape is less than the width L2 between the two retaining bars 30, and the effect of replenishing the tape 200 can also be achieved through the action of the replenishing mechanism 40.
[0039] Please refer to the figure. In an embodiment of the present utility model, in order to facilitate the control of the input and pause of the powder in the replenishing mechanism 40, the replenishing mechanism 40 further includes a baffle 43. The baffle 43 is slidably arranged relative to the replenishing hopper 41 and is used to block or open the opening of the replenishing hopper 41. In this way, by sliding the baffle 43, the opening of the replenishing hopper 41 can be opened or blocked, so as to facilitate the control of the powder feeding and blocking, and can adapt to the feeding action of the feed hopper 20.
[0040] Further, please refer to Figure 2 , in an embodiment of the present utility model, in order to facilitate obtaining tapes 200 with different widths, the powder processing device 100 further includes a material blocking adjustment mechanism 50. The material blocking adjustment mechanism 50 is connected to the retaining bar 30 and is used to drive the retaining bar 30 to move along the width direction of the tape 200, so as to adjust the distance between the two retaining bars 30, so as to achieve the effect of adjusting the width of the tape 200.
[0041] Among them, the material blocking adjustment mechanism 50 can be a driving component composed of a driving motor and a lead screw. Under the drive of the driving motor, the retaining bar 30 connected to the lead screw can move along the width direction of the tape 200, so as to adjust the distance between the two retaining bars 30, so as to achieve the effect of adjusting the width of the tape 200.
[0042] Further, corresponding to the adjustable width of the retaining bar 30, please refer toFigures 2 to 4 In an embodiment of the present utility model, the powder processing device 100 further includes a feeding adjustment mechanism 60. The feeding adjustment mechanism 60 is connected to the feeding mechanism 40 and is used to drive the feeding mechanism 40 to move along the width direction of the material belt 200. In this way, the feeding mechanism 40 can be adjusted according to the width of the material belt 200 as needed, so as to adjust the feeding amount in the collapsed angle of repose α.
[0043] Among them, the feeding adjustment mechanism 60 can be a mechanism driven by a motor and a lead screw. Under the drive of the motor, the lead screw rotates, thereby driving the feeding mechanism 40 to move along the width direction of the material belt 200.
[0044] In this way, through the adjustment of the retaining strip 30 and the feeding mechanism 40 by their respective adjustment mechanisms, the width of the material belt 200 required for adjustment can be achieved, improving the practicability of the entire powder processing device 100.
[0045] Please refer to Figure 2 and Figure 4 When installing the feeding adjustment mechanism 60, the powder processing device 100 further includes a fixing frame 70. The fixing frame 70 is arranged above the conveying mechanism 10 along the width direction of the material belt 200 and is used to install two feeding adjustment mechanisms 60. In this way, by setting one fixing frame 70, the installation of the two feeding adjustment mechanisms 60 can be realized.
[0046] Furthermore, in order to facilitate driving the movement of the feeding mechanism 40, a guide rail 71 can be provided on the fixing frame 70, and a sliding groove 72 can be provided on the feeding mechanism 40, so as to facilitate guiding the movement of the feeding mechanism 40.
[0047] Please refer to Figure 2 In order to fix the end of the retaining strip 30, the powder processing device 100 further includes a material retaining pushing mechanism 80. The material retaining pushing mechanism 80 is used to abut against the retaining strip 30. Specifically, it abuts against the end of the retaining strip 30 along the movement direction of the powder, so as to ensure that the retaining strip 30 can extend along its own length direction to ensure the constraint effect on the powder.
[0048] It can be understood that, please refer to Figure 3 Since the powder will be pressed into a green brick 300 after being laid out, the powder processing device 100 of this embodiment further includes a roll pressing mechanism 90. The roll pressing mechanism 90 is arranged at the end of the conveying direction of the conveying mechanism 10 and is used to roll the material belt 200 into a green brick 300, so that the powder can be formed on one production line.
[0049] Specifically, the roll pressing mechanism 90 includes a driving device 91, a pair of forming rolls 92, a pair of driving rolls 93, and a pair of driven rolls 94. For the schematic diagrams of the strip 200 formed before roll pressing and the green brick 300 formed after roll pressing, please refer to Figure 3 shown below.
[0050] In summary, by feeding the strip 200 in the width direction through the feeding mechanism 40, the collapse on both sides in the width direction of the strip 200 is avoided, so that the powder thickness on both sides in the width direction of the strip 200 and the middle area can be consistent, thereby ensuring that each area of the powder has the same thickness and density when being compacted.
[0051] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions formed by any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
