Description

Technical Field

[0001] The present invention belongs to the technical field of concrete material 3D printing equipment, and particularly relates to a concrete material 3D printing equipment with an automatic feeding mechanism. Background Art

[0002] Concrete 3D printing equipment is an intelligent technology that constructs structures by extruding concrete materials layer by layer. Combining a numerical control system, an extrusion device, and special materials, it realizes moldless rapid construction. This technology can efficiently complete complex geometric shapes, reduce material waste, and is applicable to projects such as buildings and bridges. Some equipment supports fiber or steel bar reinforcement to enhance the structural performance and promote the development of green construction and building digitization; this device is used for 3D printing of relatively small concrete workpieces; Most of the feeding structures in existing concrete 3D printing equipment adopt a single-station design, and the waste on the surface of the feeding mechanism inside is also cleaned separately by an independent cleaning structure. Therefore, this not only makes the concrete 3D printing equipment have low efficiency during operation, but also the independent operation of the cleaning mechanism requires an independent drive source, which will increase the usage cost of the equipment. Summary of the Invention

[0003] The purpose of the present invention is to provide a concrete material 3D printing equipment with an automatic feeding mechanism, and its advantages are dual-station switching, automatic feeding, station cleaning, and cleaning of the cleaning structure.

[0004] The above technical purpose of the present invention is achieved through the following technical solutions: A concrete material 3D printing equipment with an automatic feeding mechanism, including a device main body, a material storage shell is detachably connected inside the lower end of the device main body, a connection shell is welded to the upper end of the device main body, a feeding assembly is arranged inside the connection shell, and a cleaning assembly is arranged on the surface of the feeding assembly.

[0005] By adopting the above technical solutions, the feeding assembly can perform dual-station switching and can automatically feed materials. The cleaning assembly can scrape the waste dripping on the station during the feeding process, and the cleaning assembly can also clean the scraping structure.

[0006] The present invention is further configured as: The feeding assembly includes a motor, the motor is bolted to one side of the upper end of the device main body, two groups of first connecting plates are welded on both sides of the connection shell, a reciprocating lead screw is rotatably connected inside the corresponding two groups of first connecting plates, and one of the reciprocating lead screws is fixedly connected to the output end of the motor through a coupling.

[0007] By adopting the above technical solutions, the operation of the motor will drive the reciprocating lead screw to rotate.

[0008] The present invention is further configured such that: one end of the reciprocating lead screw is fixedly connected to a runner, and a belt is commonly driven and connected to the surfaces of the two runners. A threaded plate is threadedly connected to the surface of the reciprocating lead screw, and the threaded plate is slidably connected to the holes on both sides of the connecting shell. Two processing plates are slidably connected inside the connecting shell.

[0009] With the above technical solution, the rotation of the reciprocating lead screw will drive the threaded plate to move reciprocally.

[0010] The present invention is further configured such that: both ends of one side of each processing plate are welded with a first toothed plate, and the first toothed plate is welded to the threaded plate. Two first limiting wheels are rotatably connected to the inner parts of both sides of the connecting shell. One end of each first limiting wheel is welded with a first circular gear, and the first circular gear is meshed and connected with the corresponding two first toothed plates. Two through holes are formed on the surface of each processing plate.

[0011] With the above technical solution, the movement of the threaded plate will drive the first toothed plate and the processing plate to move. The movement of the lower first toothed plate will drive the upper first toothed plate to move in an opposite or reverse direction by using the first circular gear.

[0012] The present invention is further configured such that: two second connecting plates are welded to the upper and lower ends of each of the two processing plates respectively. Two threaded rods are rotatably connected to the inside of the corresponding two second connecting plates. One end of each threaded rod is fixedly connected to a second bevel gear. One end of one side of the first toothed plate is rotatably connected to a second limiting wheel.

[0013] With the above technical solution, the threaded rod will be driven to rotate by the second bevel gear driven by the first bevel gear.

[0014] The present invention is further configured such that: one end of each second limiting wheel is fixedly connected to a second circular gear. One side of the second circular gear is fixedly connected to a first bevel gear, and the first bevel gear is meshed and connected with the second bevel gear. Two second toothed plates are welded to both sides of the inner wall of the connecting shell, and the second toothed plate is meshed and connected with the second circular gear. A top plate is commonly threadedly connected to the surfaces of the corresponding two threaded rods.

[0015] With the above technical solution, the movement of the first toothed plate will drive the second circular gear to rotate on the surface of the second toothed plate, thereby driving the first bevel gear to rotate, and finally driving the top plate to move to automatically discharge the workpiece.

[0016] The present invention is further configured such that: the cleaning assembly includes a third connecting plate. Four third connecting plates are respectively welded to both ends of one side of the top plate. One side of the third connecting plate is bolted with a spring ejector rod. The piston end of the spring ejector rod is bolted with a limiting plate.

[0017] With the above technical solution, the spring ejector rod can limit the scraping wheel by using the limiting plate, and the scraping wheel can rotate between the two limiting plates.

[0018] The present invention is further configured such that: a scraping wheel is detachably connected inside the four groups of the limiting plates, a third circular gear is fixedly connected to one end of the scraping wheel, third toothed plates are welded to both sides of the inner wall of the processing plate, and a plurality of groups of inclined plates are fixedly connected to one side of the third toothed plates.

[0019] With the above technical solution, when the third circular gear rotates and moves forward on the surface of the third toothed plate, when the third circular gear reaches the position of the inclined plate and presses the inclined plate, since both sides of the inclined plate are inclined surfaces and the surface is relatively smooth due to the tempered glass material, the third circular gear will drive the scraping wheel to shift by using the spring ejector rod. When the third circular gear passes over the inclined plate, the spring ejector rod will drive the third circular gear to reset. In this way, the vibration generated by the impact between the third circular gear and the third gear will cause the waste on the surface of the scraping wheel to fall off, achieving the effect of facilitating the removal of the waste on the surface of the scraping wheel.

[0020] The present invention is further configured such that: second motors are bolted to both sides of the upper end of the device main body, a first one-way lead screw is fixedly connected to the output ends of the second motors through a coupling, limiting rods are welded to both sides inside the device main body, an electric slide table is jointly arranged on the surfaces of a corresponding group of the first one-way lead screw and the limiting rod, the electric slide table is in threaded connection with the first one-way lead screw, and the electric slide table is in sliding connection with the limiting rod. A moving plate is jointly threaded between the two electric slide tables, a third motor is bolted to one side of the upper end of the moving plate, and a second one-way lead screw is fixedly connected to the output end of the third motor through a coupling. A discharge head is jointly arranged between the second one-way lead screw and the moving plate.

[0021] With the above technical solution, when the second motor operates, it will drive the first one-way lead screw to rotate, thereby driving the electric slide table to move up and down. During the movement, the limiting rod is used to limit the movement of the electric slide table. When the electric slide table operates, it will drive the moving plate to move horizontally. And when the third motor operates, it will drive the second one-way lead screw to rotate, thereby driving the discharge head to move.

[0022] In summary, the present invention has the following beneficial effects: During use, since the surface of the blanking component is a two-station design, when printing is completed on the surface of one station, this station will be moved outwards. During the movement, the other station will synchronously move to the working area. And when the station moves outwards, the internal blanking mechanism will automatically push the workpiece outwards. Because during operation, a shell suitable for the size of the workpiece will be placed on the station, and during the printing process, printing will be carried out inside this shell, which is convenient for blanking until this shell and the workpiece are pushed into the external device. And because during 3D printing, there will inevitably be some waste materials falling on other parts of the station, so during the blanking process of the workpiece, the cleaning component will automatically scrape the waste materials on the surface of the station. When the workpiece moves to the appropriate position, the cleaning component will use vibration to separate the waste materials on the surface of the cleaning mechanism to prevent affecting subsequent use, achieving the effect of effectively improving the use efficiency of the 3D printing device.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Embodiment 1: Refer to Figures 1-10 , a 3D printing device for concrete materials with an automatic feeding mechanism, including a device main body 1, a material storage shell 3 is detachably connected to the lower end inside the device main body 1, a connection shell 4 is welded to the upper end of the device main body 1, a feeding assembly 5 is arranged inside the connection shell 4, and a cleaning assembly 6 is arranged on the surface of the feeding assembly 5; second motors 7 are bolted to both sides of the upper end of the device main body 1, a first one-way lead screw 8 is fixedly connected to the output ends of the second motors 7 through a coupling, limiting rods 9 are welded to both sides inside the device main body 1, an electric slide 10 is jointly arranged on the surfaces of a corresponding group of the first one-way lead screw 8 and the limiting rod 9, the electric slide 10 is threadedly connected to the first one-way lead screw 8, and the electric slide 10 is slidably connected to the limiting rod 9, a moving plate 13 is jointly threadedly connected between the two electric slides 10, a third motor 11 is bolted to one side of the upper end of the moving plate 13, a second one-way lead screw 12 is fixedly connected to the output end of the third motor 11 through a coupling, and a discharge head 2 is jointly arranged between the second one-way lead screw 12 and the moving plate 13.

[0027] Brief description of the use process: When in use, since the surface of the blanking component 5 is a double-station design, when printing is completed on the surface of one station, the station will be moved outward. During the movement, the other station will be moved to the working area synchronously, and when the station is moving outward, the internal blanking mechanism will automatically push the workpiece outward, because when working, a shell suitable for the size of the workpiece will be placed on the station. During the printing process, printing will be done inside the shell, which is convenient for blanking until the shell and the workpiece are pushed into the external device. In addition, during 3D printing, it is inevitable that some waste will fall on other parts of the station, so the workpiece will be cleaned up during the blanking process. Component 6 automatically scrapes off the waste on the surface of the workstation. When the workpiece moves to the appropriate position, the cleaning component 6 will separate the waste on the surface of the cleaning mechanism by vibration to prevent it from affecting subsequent use. When the second motor 7 is running, it will drive the first one-way screw 8 to rotate, thereby driving the electric slide 10 to move up and down. During the movement, the limit rod 9 is used to limit the movement of the electric slide 10. When the electric slide 10 is running, it will drive the moving plate 13 to move horizontally, and when the third motor 11 is running, it will drive the second one-way screw 12 to rotate, thereby driving the discharge head 2 to move, thereby effectively improving the efficiency of the 3D printing equipment.

[0028] Embodiment 2: Based on Example 1, Figure 2 、 Figures 4-7 、 Figures 9-10, the blanking assembly 5 includes a motor 501, the motor 501 is bolted to one side of the upper end of the device main body 1, two groups of first connecting plates 505 are welded on both sides of the connecting shell 4, and a reciprocating screw rod 502 is rotatably connected between the corresponding two groups of first connecting plates 505, and one of the reciprocating screw rods 502 is fixedly connected to the output end of the motor 501 through a coupling; a runner 503 is fixedly connected to one end of the reciprocating screw rod 502, a belt 504 is commonly driven on the surfaces of the two runners 503, a threaded plate 506 is threadedly connected to the surface of the reciprocating screw rod 502, and the threaded plate 506 is slidably connected to the holes on both sides of the connecting shell 4, and two processing plates 518 are slidably connected inside the connecting shell 4; two first toothed plates 507 are welded at both ends of one side of the processing plate 518, and the first toothed plate 507 and the threaded plate 506 are welded, and two first limiting wheels 509 are rotatably connected to the inner sides of both sides of the connecting shell 4, a first circular gear 510 is welded to one end of the first limiting wheel 509, and the first circular gear 510 is meshed with the corresponding two groups of first toothed plates 507, and two through holes 519 are formed on the surface of the processing plate 518; two second connecting plates 515 are welded at both upper and lower ends of the two processing plates 518 respectively, a threaded rod 516 is rotatably connected inside the corresponding two groups of second connecting plates 515, a second bevel gear 514 is fixedly connected to one end of the threaded rod 516, and a second limiting wheel 511 is rotatably connected to one end of one side of the first toothed plate 507; a second circular gear 512 is fixedly connected to one end of the second limiting wheel 511, a first bevel gear 513 is fixedly connected to one side of the second circular gear 512, and the first bevel gear 513 is meshed with the second bevel gear 514, and two second toothed plates 508 are welded to both inner walls of the connecting shell 4, and the second toothed plate 508 is meshed with the second circular gear 512, and a top plate 517 is commonly threadedly connected to the surfaces of the corresponding two groups of threaded rods 516.

[0029] Brief description of the usage process: When the workpiece on the surface of the lower processing plate 518 is manufactured, start the motor 501. The motor 501 will drive one set of reciprocating lead screws 502 to rotate clockwise. This set of reciprocating lead screws 502 will drive the other set of reciprocating lead screws 502 to rotate clockwise by using the runner 503 and the belt 504. While the reciprocating lead screws 502 are rotating, they will cause the threaded plate 506 to move inside the connecting shell 4, and drive the first toothed plate 507 and the processing plate 518 to move outward inside the connecting shell 4. Since the first circular gear 510 is located between the two sets of first toothed plates 507 and is in a meshing state with both sets of first toothed plates 507, when the lower first toothed plate 507 moves outward, it will cause the upper first toothed plate 507 to drive the upper processing plate 518 to move inward. During the outward movement of the processing plate 518, it will cause the second circular gear 512 to rotate and move by using the second toothed plate 508. The second circular gear 512 can rotate inside the first toothed plate 507 by using the second limiting wheel 511. During the rotation of the second circular gear 512, it will drive the second bevel gear 514 and the threaded rod 516 to rotate by using the first bevel gear 513. The second circular gear 512, the first bevel gear 513, the second bevel gear 514 and the threaded rod 516 will move along with the movement of the first toothed plate 507. During the rotation of the threaded rod 516, it will cause the top plate 517 to move forward and push the workpiece forward until the workpiece is pushed off the processing plate 518 at one end of the processing plate 518. The reciprocating lead screws 502 are used to drive the two sets of processing plates 518 to reciprocally switch positions, achieving the effect of facilitating automatic blanking of the workpiece and effectively improving the efficiency with the double-station design.

[0030] Embodiment 3: On the basis of Embodiment 2, referring to Figure 6 , Figure 8 , the cleaning component 6 includes a third connecting plate 604. Four groups of third connecting plates 604 are respectively welded to both ends of one side of the top plate 517. A spring ejector rod 605 is bolted to one side of the third connecting plate 604. A limiting plate 606 is bolted to the piston end of the spring ejector rod 605. A scraping wheel 601 is detachably connected inside the four groups of limiting plates 606. One end of the scraping wheel 601 is fixedly connected to a third circular gear 603. Third toothed plates 602 are welded to both sides of the inner wall of the processing plate 518. A plurality of inclined plates 607 are fixedly connected to one side of the third toothed plate 602.

[0031] Brief description of the usage process: The spring ejector rod 605 can limit the scraping wheel 601 by using the limiting plate 606, and the scraping wheel 601 can rotate between the two groups of limiting plates 606. The scraping wheel 601 is used to scrape the waste on the surface of the processing plate 518 during the process of following the top plate 517. When the scraping wheel 601 moves forward, it will cause the third circular gear 603 to rotate and move forward on the surface of the third toothed plate 602. When the third circular gear 603 reaches the position of the inclined plate 607 and presses the inclined plate 607, since both sides of the inclined plate 607 are inclined surfaces and the surface is relatively smooth due to the tempered glass material, the third circular gear 603 will drive the scraping wheel 601 to shift by using the spring ejector rod 605. When the third circular gear 603 passes over the inclined plate 607, the spring ejector rod 605 will drive the third circular gear 603 to reset. In this way, the vibration generated by the impact between the third circular gear 603 and the third gear will cause the waste on the surface of the scraping wheel 601 to fall off. The fallen waste will enter the material receiving shell 3 from the position of the through hole 519. At the same time, during printing, a plate for placing the printed object will be placed on the processing plate 518, and the width of this plate is more than twice the width of the through hole 519 to prevent the plate from being stuck in the through hole 519 when it moves. The material receiving shell 3 can be disassembled and cleaned, achieving the effect of facilitating the removal of the waste on the surface of the scraping wheel 601.
