Description

Technical Field

[0001] This invention relates to the field of building equipment technology, and more specifically, to a synchronous feeding reinforced concrete 3D printing device and method. Background Technology

[0002] Concrete 3D printing, as an emerging building manufacturing process, is a building technology that can quickly complete buildings. In traditional building processes, the pouring method is used to combine concrete with steel bars, with the steel bars wrapped in concrete, thereby improving the ductility and durability of the concrete.

[0003] Currently, existing concrete 3D printing devices often suffer from the following technical problems during the printing process:

[0004] Existing concrete 3D printing equipment cannot position and fix sheets of different widths and sizes when simultaneously conveying concrete and sheets. It also requires changing the positioning and clamping structure according to the size of the conveyed sheet, which is inconvenient. Furthermore, existing concrete 3D printing equipment cannot effectively bond steel bars with concrete, making it impossible to print complex structures. This results in lower strength, relatively weakened resistance to deformation, and reduced mechanical properties of the printed product. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a synchronous sheet feeding reinforced concrete 3D printing device and method that can position and fix stacked sheets of different widths without requiring changes to the positioning and clamping structure based on the sheet width. Furthermore, the entire process can mimic the brick-and-mortar structure of traditional buildings to improve the mechanical properties of the printed product, resulting in a tight fit and good bonding between the concrete and the sheet. This provides convenience for the synchronous conveying process of the concrete and sheet.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A synchronous feeding reinforced concrete 3D printing device includes a base assembly on which a stacking assembly is mounted and fixed.

[0008] The stacking assembly includes a placement member, two clamping members slidably disposed on the placement member, and an adjusting member slidably disposed on one side of the placement member.

[0016] The present invention is further configured such that: the base assembly includes a base component, a turntable component rotatably disposed on the base component, and a guide component slidably disposed inside the base component.

[0017] The base component includes a supporting base plate, and a movable groove is provided on one side of the supporting base plate. The U-shaped sliding plate slides in cooperation with the movable groove.

[0018] The present invention is further configured such that: a U-shaped mounting plate is fixed on the top of the supporting base plate, and the U-shaped mounting plate has several positioning holes on both sides near the bottom.

[0019] Both L-shaped plates have threaded fastening bolts on one side near the bottom, and the fastening bolts are threadedly connected to the positioning holes.

[0020] The present invention is further configured such that: a drive motor is fixed on one outer side of the U-shaped mounting plate, the output shaft of the drive motor passes through one outer side of the U-shaped mounting plate, and the output shaft of the drive motor is rotatably engaged with the U-shaped mounting plate.

[0021] The turntable component includes a mounting cylinder, on one side of which a rotating cylinder is fixed, and the mounting cylinder is fixedly installed with the output shaft of the drive motor.

[0022] The present invention is further configured such that: a turntable is fixed on the outer peripheral side of the rotating drum, a lever is fixed at the bottom center of the turntable, and a limit plate is fixed at the bottom of the lever.

[0023] A limiting ring is fixed to the inner wall of the U-shaped mounting plate, and the rotating cylinder is in rotatable engagement with the limiting ring.

[0024] The invention is further configured such that: a vertical rod is fixed at the top of the supporting base plate inside the U-shaped mounting plate, and a guide groove is provided on one side of the vertical rod near the bottom.

[0025] The material guide includes an L-shaped material guide plate, which slides in conjunction with the guide groove.

[0026] The present invention is further configured such that: a connecting rod is fixed to the top of the L-shaped guide plate, a displacement plate is fixed to one end of the connecting rod, a vertical groove is provided through one side of the displacement plate, and the lever is slidably engaged with the vertical groove.

[0027] The bottom of the displacement plate is fixed with an anti-deviation rail.

[0028] The top of the support base plate is provided with an anti-deviation groove inside the U-shaped mounting plate, and the anti-deviation groove slides in conjunction with the anti-deviation rail.

[0029] The present invention is further configured such that: a mounting groove is provided on one side of the U-shaped mounting plate, and a mounting hole is provided through the top of the U-shaped mounting plate.

[0030] The bottom of the supporting base plate is fixed with two symmetrical side plates, and the two side plates are rotatably connected by a pressure roller through a rotating shaft.

[0031] The top of the support base plate has a snap-fit ​​groove on the side away from the U-shaped mounting plate, and the snap-fit ​​groove is engaged with the fixing plate.

[0032] The present invention is further configured to include the following methods:

[0033] T1. Before use, the mounting holes through the top of the U-shaped mounting plate can be connected and fixed to the print head of the concrete 3D printer by bolts to facilitate the synchronous conveying of concrete and sheet materials in the later stage.

[0034] T2. When it is necessary to stack and clamp sheets of different widths and sizes, the U-shaped sliding plate can slide left and right inside the moving groove, so that the two hinged arms can rotate in a relatively contracted or expanded state, thereby providing a force for the two support plates to move closer or further away from each other, driving the two cross rails to move closer or further away from each other inside the two cross grooves respectively.

[0035] T3. When the two cross rails are close to or far apart inside the two cross grooves, they can be further guided by the sliding fit between the rectangular groove and the transverse plate. This enables the positioning and fixing of stacked sheets of different widths and sizes, preventing the stacked sheets from tipping over during the synchronous conveying of concrete and sheets.

[0036] T4. After the positioning and clamping work is completed, firstly, the U-shaped slide plate that slides inside the moving groove can be threadedly fixed by the threaded connection between the fastening bolt and the positioning hole to prevent the U-shaped slide plate from sliding inside the moving groove. Then, the snap-fit ​​between the snap-fit ​​groove and the fixing plate and the sliding connection between the U-shaped vertical plate and the U-shaped mounting plate can be used, and the snap-fit ​​groove and the fixing plate can be connected and fixed with bolts at the same time to complete the assembly and fixing between the stacked assembly and the base assembly.

[0037] After the actions of T5 and T1 to T4 are completed, the drive motor fixed on one outer side of the U-shaped mounting plate can be started to make the rotating drum rotate circumferentially on the circumferential side of the limiting ring. Through the sliding cooperation between the lever and the vertical groove, the displacement plate is driven to move back and forth in the left and right directions inside the U-shaped mounting plate.

[0038] T6. When the displacement plate moves back and forth in the left and right direction inside the U-shaped mounting plate, its L-shaped guide plate will also move back and forth in the left and right direction inside the guide groove at the same time. During the left and right reciprocating movement, the L-shaped guide plate can be limited by the sliding cooperation between the anti-deviation groove and the anti-deviation rail to prevent it from deviating and avoid affecting the subsequent sheet material conveying.

[0039] During the reciprocating movement in steps T7 and T6, as the L-shaped guide plate moves to the left, the bottom sheet can be slid out, allowing the bottom layer of stacked sheets to slide out from the bottom and finally be discharged through the discharge chute opened near the bottom on one side of the convex vertical plate, and then placed at intervals on the concrete surface printed by the concrete 3D printer.

[0040] T8. The sheets arranged at intervals on the concrete surface can be further compacted by the pressure rollers that rotate between the two side plates via a pivot, so that the concrete and the sheets fit together tightly and have a good bonding effect.

[0041] The advantages of this invention are:

[0042] 1. This invention uses the process of the two side clamps moving closer or further apart to position and fix stacked sheets of different widths, preventing the stacked sheets from tipping over during the synchronous transport of concrete and sheets. The entire process does not require changing the positioning and clamping structure according to the width of the sheets, thus bringing certain convenience to the synchronous transport of concrete and sheets.

[0043] 2. This invention uses the L-shaped guide plate to move back and forth inside the guide groove, which can slide and export the bottom sheet material. Then, it is exported through the discharge groove opened near the bottom on one side of the convex vertical plate. The whole process can imitate the brick-mud structure of traditional buildings, thereby improving the mechanical properties of the printed product, making the concrete and sheet material fit tightly and have a good bonding effect.

[0044] 3. This invention can arrange multiple sheets at intervals on the concrete surface printed by the concrete 3D printer through the material guide, and finally compact them through the pressure rollers that rotate between the two side plates, so that the concrete and the sheets are closely matched and have a good bonding effect.

[0062] Please see Figure 1-12 The present invention provides the following technical solutions:

[0063] A synchronous feeding reinforced concrete 3D printing device and method, specifically, includes a base assembly 1, on which a stacking assembly 2 is mounted and fixed; the stacking assembly 2 includes a placement member 3, two clamping members 4 slidably disposed on the placement member 3, and an adjusting member 5 slidably disposed on one side of the placement member 3; the adjusting member 5 is hinged to the two clamping members 4; the adjusting member 5 includes a U-shaped sliding plate 501, with L-shaped plates 502 fixed to both outer sides of the U-shaped sliding plate 501, and a first hinge post 503 fixed to the top of the L-shaped plate 502. The peripheral side is hinged with a hinge arm 504, and the top of the hinge arm 504 has a through hinge hole 505; the clamping member 4 includes a cross rail 401, the top of the cross rail 401 is fixed with a side clamping plate 402, one side of the side clamping plate 402 is fixed with a support plate 403, the top of the support plate 403 is fixed with a second pin 404, and the hinge hole 505 is hinged with the second pin 404; the placement member 3 includes a fixing plate 301, the top of the fixing plate 301 is fixed with two symmetrical T-shaped plates 302, and each of the two T-shaped plates 302 has a cross groove 303 on one opposite side. Two cross grooves 303 are slidably engaged with two cross rails 401 respectively; a protruding vertical plate 304 is fixed to the top of each of the two T-shaped plates 302, and a discharge groove 305 is opened on one side of the protruding vertical plate 304 near the bottom; a symmetrical U-shaped vertical plate 306 is fixed to one side of the fixed plate 301, and a horizontal plate 307 is fixed to the two outer sides of the U-shaped vertical plate 306; a rectangular plate 405 is fixed to one side of the side clamping plate 402, and a rectangular groove 406 is opened on one side of the rectangular plate 405, which is slidably engaged with the horizontal plate 307; the base assembly 1 includes a base part 6, which is rotatably mounted on the base. The base component 6 includes a turntable component 7 placed on the base component 6 and a guide component 8 slidably disposed inside the base component 6; the base component 6 includes a supporting base plate 601, a moving groove 602 is provided on one side of the supporting base plate 601, and a U-shaped sliding plate 501 is slidably engaged with the moving groove 602; a U-shaped mounting plate 603 is fixed to the top of the supporting base plate 601, and a number of positioning holes 604 are provided on both sides of the U-shaped mounting plate 603 near the bottom; fastening bolts 506 are threadedly connected to one side of the two L-shaped plates 502 near the bottom, and the fastening bolts 506 are threadedly connected to the positioning holes 604.

[0064] The specific application of this embodiment is as follows: When it is necessary to stack and clamp sheets of different widths, the U-shaped sliding plate 501 can slide left and right inside the moving groove 602, so that the two hinged arms 504, which are connected between the first hinge post 503 and the second pin 404, can rotate in a relatively contracted or expanded state. This provides a force for the two support plates 403 fixedly connected to the bottom of the second pin 404 to move closer or further away from each other, thereby driving the cross rails 401 fixed to the bottom of the two side clamping plates 402 to move closer or further away from each other inside the cross grooves 303 opened on the opposite side of the two T-shaped plates 302. When the cross rails 401 fixed to the bottom of the two side clamping plates 402 move closer or further away from each other inside the cross grooves 303 opened on the opposite side of the two T-shaped plates 302, the cross rails 401 fixed to the bottom of the two side clamping plates 402 move closer or further away from each other. When the cross grooves 303 move closer or further apart, they can be further guided by the sliding fit between the rectangular groove 406 and the transverse plate 307. After the above actions are completed, the U-shaped sliding plate 501, which is slidingly fitted inside the moving groove 602, can be threadedly fixed by the threaded connection between the fastening bolt 506 and the positioning hole 604 to prevent the U-shaped sliding plate 501 from sliding inside the moving groove 602. This achieves the positioning and fixing of stacked sheets of different widths and sizes, preventing the stacked sheets from tipping over during the synchronous conveying of concrete and sheets. Moreover, the entire process does not require the replacement of the positioning and clamping structure according to the width of the sheets, which brings certain convenience to the synchronous conveying process of concrete and sheets.

[0065] Example 2

[0066] Please see Figure 1-12This second embodiment is an improvement on the first embodiment as follows: Specifically, a drive motor 605 is fixed to one outer side of the U-shaped mounting plate 603, and the output shaft of the drive motor 605 passes through one outer side of the U-shaped mounting plate 603, and the output shaft of the drive motor 605 is rotatably engaged with the U-shaped mounting plate 603; the turntable component 7 includes a mounting cylinder 701, a rotating cylinder 702 is fixed to one side of the mounting cylinder 701, and the mounting cylinder 701 is fixedly mounted to the output shaft of the drive motor 605; a turntable 703 is fixed to the outer periphery of the rotating cylinder 702, a lever 704 is fixed to the bottom of the turntable 703 at a position slightly off-center, and a limit plate 705 is fixed to the bottom of the lever 704; a limit ring 606 is fixed to the inner wall of the U-shaped mounting plate 603, and the rotating cylinder 702 is rotatably engaged with the limit ring 606; a vertical rod 607 is fixed to the top of the support base plate 601 inside the U-shaped mounting plate 603, and a guide groove 608 is opened on one side of the vertical rod 607 near the bottom; the guide component 8 includes... L-shaped guide plate 801, which slides in conjunction with guide groove 608; a connecting rod 802 is fixed to the top of L-shaped guide plate 801, and a displacement plate 803 is fixed to one end of connecting rod 802; a vertical groove 804 is opened through one side of displacement plate 803, and a lever 704 slides in conjunction with vertical groove 804; an anti-deviation rail 805 is fixed to the bottom of displacement plate 803; an anti-deviation groove 609 is opened at the top of support base plate 601 inside U-shaped mounting plate 603 to prevent... The eccentric groove 609 slides with the anti-eccentric rail 805; a mounting groove 610 is provided on one side of the U-shaped mounting plate 603, and a mounting hole 611 is provided through the top of the U-shaped mounting plate 603; symmetrical two side plates 612 are fixed at the bottom of the support base plate 601, and a pressure roller 613 is rotatably engaged between the two side plates 612 through a rotating shaft; a snap-fit ​​groove 614 is provided on the top side of the support base plate 601 away from the U-shaped mounting plate 603, and the snap-fit ​​groove 614 is snap-fit ​​engaged with the fixing plate 301.

[0067] The specific application of this embodiment two is as follows: Before use, the mounting hole 611 through the top of the U-shaped mounting plate 603 can be connected and fixed to the print head of the concrete 3D printer using bolts to facilitate the synchronous conveying of concrete and sheet materials later. Additionally, the snap-fit ​​between the snap-fit ​​groove 614 and the fixing plate 301, and the sliding connection between the U-shaped vertical plate 306 and the U-shaped mounting plate 603, can be used. Subsequently, the snap-fit ​​groove 614 and the fixing plate 301 are connected and fixed with bolts, so that the fixing plate 301 is fixedly connected to the top of the base assembly 1 for positioning and fixing sheets of different widths and sizes. After the above work is completed, Multiple sheets of the same width are stacked together. Then, by activating the drive motor 605 fixed to the outer side of the U-shaped mounting plate 603, the rotating drum 702 rotates circumferentially around the circumference of the limiting ring 606. As the rotating drum 702 rotates around the circumference of the limiting ring 606, the sliding engagement between the lever 704 fixed at the bottom center of the turntable 703 and the vertical slot 804 penetrating one side of the displacement plate 803 drives the displacement plate 803 to reciprocate left and right within the U-shaped mounting plate 603. During operation, the L-shaped guide plate 801 also moves back and forth within the guide groove 608 near the bottom of the vertical rod 607. When the L-shaped guide plate 801 moves back and forth within the guide groove 608 near the bottom of the vertical rod 607, the sliding engagement between the anti-deviation groove 609 and the anti-deviation rail 805 limits its movement, preventing it from shifting and affecting subsequent sheet material transport. During this reciprocating motion, as the L-shaped guide plate 801 moves to the left, the bottom layer of sheet material is slidably discharged, allowing the bottom layer of stacked sheets to slide out from the bottom. Finally, the material is discharged through the discharge chute 305 opened near the bottom on one side of the convex vertical plate 304 and placed on the concrete surface printed by the concrete 3D printer. Subsequently, as the concrete 3D printer continues to print, the device can repeatedly discharge the sheet, so that multiple sheets are placed at intervals on the concrete surface printed by the concrete 3D printer. The sheets arranged at intervals on the concrete surface can be further compacted by the pressure rollers 613 that rotate and cooperate between the two side plates 612. The whole process can imitate the brick-mud structure of traditional buildings to improve the mechanical properties of the printed product, so that the concrete and the sheet are closely matched and have a good bonding effect.

[0068] The working principle of this invention is as follows:

[0069] Before use, the mounting holes 611 through the top of the U-shaped mounting plate 603 can be connected and fixed to the print head of the concrete 3D printer using bolts to facilitate the synchronous conveying of concrete and sheet materials later. When it is necessary to stack and clamp sheets of different widths, the U-shaped sliding plate 501 can slide left and right inside the moving groove 602, causing the two hinged arms 504 to rotate in a relatively contracted or expanded state. This provides a force for the two support plates 403 to move closer or further apart, causing the two cross rails 401 to move closer or further apart inside the two cross grooves 303. When the two cross rails 401 move closer or further apart inside the two cross grooves 303, their... The sliding fit between the rectangular groove 406 and the transverse plate 307 further guides the material, thereby positioning and fixing stacked sheets of different widths and sizes to prevent them from tipping over during the synchronous conveying of concrete and sheets. After the positioning and clamping work is completed, the U-shaped sliding plate 501, which is slidingly fitted inside the moving groove 602, is threadedly fixed through the threaded connection between the fastening bolt 506 and the positioning hole 604 to prevent the U-shaped sliding plate 501 from sliding inside the moving groove 602. Then, the snap-fit ​​fit between the snap-fit ​​groove 614 and the fixing plate 301, and the sliding connection between the U-shaped vertical plate 306 and the U-shaped mounting plate 603 are achieved through the snap-fit ​​fit between the snap-fit ​​groove 406 and the fixing plate 301, and the sliding connection between the U-shaped vertical plate 306 and the U-shaped mounting plate 603. At the same time, the snap-fit ​​groove 614 is secured with bolts. 14 is connected and fixed to the fixing plate 301 to complete the assembly and fixation between the stacked sheet assembly 2 and the base assembly 1; during the sheet unloading process, the drive motor 605 fixed to one outer side of the U-shaped mounting plate 603 can be started to make the rotating drum 702 rotate circumferentially on the circumferential side of the limiting ring 606, and through the sliding cooperation between the lever 704 and the vertical groove 804, the displacement plate 803 is driven to reciprocate left and right inside the U-shaped mounting plate 603. When the displacement plate 803 reciprocates left and right inside the U-shaped mounting plate 603, its L-shaped guide plate 801 will also reciprocate left and right inside the guide groove 608 at the same time. During the left and right reciprocating movement, the anti-deviation groove 6 The sliding engagement between 09 and the anti-deviation rail 805 limits the L-shaped guide plate 801 to prevent it from shifting and affecting the subsequent sheet material transport. During the reciprocating movement, as the L-shaped guide plate 801 moves to the left, the bottom layer of sheet material can be slid out, allowing the bottom layer of stacked sheet material to slide out from the bottom and finally be discharged through the discharge chute 305 opened near the bottom on one side of the convex vertical plate 304. The sheet material is then spaced out and placed on the concrete surface printed by the concrete 3D printer. The sheet material spaced out on the concrete surface can be further compacted by the pressure roller 613 that rotates between the two side plates 612 through the shaft, making the concrete and sheet material fit tightly and have a good bonding effect.

10. A method of using the synchronous sheet feeding reinforced concrete 3D printing device according to claim 9, characterized in that: Including the following methods: T1. Before use, the mounting hole (611) through the top of the U-shaped mounting plate (603) can be connected and fixed to the print head of the concrete 3D printer by bolts so as to carry out the synchronous conveying process of concrete and sheet in the later stage. T2. When it is necessary to stack and clamp sheets of different widths and sizes, the U-shaped sliding plate (501) can slide left and right inside the moving groove (602) so that the two hinged arms (504) can rotate in a relatively contracted or expanded state, thereby providing a force for the two support plates (403) to move closer or further away from each other, and driving the two cross rails (401) to move closer or further away from each other inside the two cross grooves (303); T3. When the two cross rails (401) are close to each other or far apart in the two cross grooves (303), they can be further guided by the sliding cooperation between the rectangular groove (406) and the transverse plate (307), so as to fix the stacked sheets of different widths and sizes, and prevent the stacked sheets from tipping over during the synchronous conveying of concrete and sheets. T4. After the positioning and clamping work is completed, firstly, the U-shaped slide plate (501) that slides in the moving groove (602) can be threadedly fixed by the threaded connection between the fastening bolt (506) and the positioning hole (604) to prevent the U-shaped slide plate (501) from sliding in the moving groove (602). Then, the snap-fit ​​between the snap-fit ​​groove (614) and the fixing plate (301) and the sliding connection between the U-shaped vertical plate (306) and the U-shaped mounting plate (603) can be completed by using bolts to connect and fix the snap-fit ​​groove (614) and the fixing plate (301). After the actions of T5, T1 to T4 are completed, the drive motor (605) fixed on one outer side of the U-shaped mounting plate (603) can be started to make the rotating drum (702) rotate circumferentially on the circumferential side of the limiting ring (606), and through the sliding cooperation between the lever (704) and the vertical groove (804), the displacement plate (803) is driven to move back and forth in the left and right directions inside the U-shaped mounting plate (603); T6. When the displacement plate (803) moves back and forth in the left and right direction inside the U-shaped mounting plate (603), its L-shaped guide plate (801) will also move back and forth in the guide groove (608) at the same time. During the left and right reciprocating movement, the L-shaped guide plate (801) can be limited by the sliding cooperation between the anti-deviation groove (609) and the anti-deviation rail (805) to prevent it from deviating and avoid affecting the subsequent sheet material conveying. During the reciprocating movement in steps T7 and T6, as the L-shaped guide plate (801) moves to the left, the bottom sheet can be slid out, so that the bottom sheet layer of the stacked sheets slides out from the bottom and is finally discharged through the discharge chute (305) opened near the bottom on one side of the convex vertical plate (304), and is placed at intervals on the concrete surface printed by the concrete 3D printer. T8. The sheets arranged at intervals on the concrete surface can be further compacted by the pressure roller (613) that rotates between the two side plates (612) through the shaft, so that the concrete and the sheets are closely matched and have a good bonding effect.
