Description

Technical Field

[0001] This invention relates to the field of 3D printing robot technology, specifically to a rail-guided mobile 3D printing robot for building construction. Background Technology

[0002] 3D printing robots are devices that combine additive manufacturing and automated control technologies to automatically stack materials layer by layer from a digital model to create three-dimensional objects. These robots are typically equipped with multi-degree-of-freedom robotic arms and extrusion systems, allowing them to handle a variety of materials, such as concrete and clay. In the construction industry, 3D printing robots using concrete enable moldless construction of walls or structural components, while in the arts and ceramics industry, 3D printing robots using clay are used to create complex shapes.

[0003] A utility model patent with publication number CN210148747U discloses a 3D printing robot for construction that can prevent building cementitious materials from solidifying during transportation, reducing reliance on workers. However, during the mixing of concrete raw materials, a large number of air bubbles are easily mixed into the concrete raw materials, affecting the subsequent printing quality. Summary of the Invention

[0030] The filter plate is installed inside the outer frame, and the shielding assembly is rotatably connected inside the outer frame.

[0031] Preferably, the shading component includes:

[0033] A sliding tube and a contact tube connected to the inside of the shielding box are slidably connected. The contact tube has a through hole inside and is used to enter the filter holes of the filter plate to wet the filter holes.

[0034] Preferably, the shading component further includes:

[0035] A connecting pipe installed at the end of the moving pipe furthest from the contact pipe;

[0036] The connecting box is located at the end of the connecting tube furthest from the moving tube. The connecting box is used to cooperate with the magnetic plate to limit the position of the shielding box.

[0037] This invention provides a rail-guided mobile 3D printing robot for building construction. It has the following advantages:

[0038] 1. This guide-rail mobile 3D printing robot for construction uses a mixing mechanism with scrapers, blades, and guide plates to mix concrete raw materials. Existing concrete mixing equipment often introduces a large number of air bubbles into the concrete raw materials during mixing, affecting subsequent printing quality. Therefore, after mixing the concrete raw materials, a guide plate drives the material through a filter plate. As the concrete raw materials pass through the filter plate, air bubbles generated during mixing are broken up, and large dry powder clumps are intercepted, thus solving the aforementioned problem.

[0039] 2. This guide-rail mobile 3D printing robot for construction utilizes a spray nozzle, chamber, and channel within its material pipe to wet the pipe wall before concrete delivery, thereby reducing the flow resistance of the concrete material. The humid environment delays the adhesion or drying of concrete on the inner wall of the pipe, facilitating subsequent cleaning. Existing equipment, when delivering high-viscosity concrete for extended periods, is prone to rapid drying and blockage of the pipe wall due to a lack of pre-lubrication. Therefore, the material pipe, along with its internal spray nozzle and channel, is designed to pre-wet the pipe wall through water spraying, reducing the risk of blockage.

[0040] 3. This guide rail mobile 3D printing robot for construction uses a mixing mechanism with a contact plate equipped with a telescopic rod in the groove inside the scraper. This, along with a rubber contact piece, allows the contact plate to automatically adjust its extension length based on its position. When the contact plate moves away from the channel, the telescopic rod is compressed, and the contact piece contacts the inner wall of the material cylinder, scraping away the attached concrete material. When the contact plate rotates back to the channel, the telescopic rod springs back to its original position, the contact plate extends slightly outward, and the contact piece rotates to scrape the surface of the filter plate, preventing the filter holes from clogging.

[0041] 4. This guide rail mobile 3D printing robot for construction uses a shielding component. Before using the equipment, a contact pipe with through holes is inserted into the filter holes of the filter plate for water lubrication, reducing the frictional resistance of the concrete material. The filter plate's closed or open state is controlled by a movable and fixed connecting box that works with a magnetic plate, and by manually adjusting the height and angle of the connecting pipe, moving pipe, contact pipe, and shielding box.

[0052] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0053] like Figures 1-9 As shown, the present invention provides a technical solution: a guide rail mobile building 3D printing robot, which is described as follows.

[0054] Including guide rail 1, it also includes:

[0055] A movable stage 2 is slidably connected inside the guide rail 1, and a power system is installed inside the movable stage 2;

[0056] The printing robot 3 and the print head 4 connected to the printing robot 3 are mounted on the mobile station 2.

[0057] The mobile carriage 7 is located outside the guide rail 1, and the delivery pump 8 is located on the mobile carriage 7. The delivery pump 8 is connected to the print head 4.

[0058] The material cylinder 10 is installed above the mobile vehicle 7;

[0059] A stirring mechanism 9 is rotatably connected inside the material cylinder 10. The stirring mechanism 9 includes a first rotating shaft 901 rotatably connected inside the material cylinder 10, a scraper 910 disposed outside the first rotating shaft 901, and a contact plate 914 disposed outside the scraper 910. The first rotating shaft 901 is used to drive the scraper 910 and the contact plate 914 to rotate inside the material cylinder 10. A motor is installed inside the moving vehicle 7. The output of the motor is connected to the first rotating shaft 901. The first rotating shaft 901 passes through the material cylinder 10, and a sealing layer is provided at the connection between the first rotating shaft 901 and the material cylinder 10.

[0060] The shelf 5 and control box 6 are located outside the guide rail 1;

[0061] The material box 11 and the material pipe 12 connected to the material box 11 are installed on the mobile vehicle 7. The material pipe 12 is connected to the conveying pump 8. The material box 11 has a small water tank and an electric valve inside. The small water tank is placed separately in the cavity of the material box 11 and does not come into contact with the concrete raw materials. The material cylinder 10 has a channel in the direction close to the material box 11.

[0062] The inner ring 13 is installed inside the material pipe 12 and at the end away from the conveying pump 8;

[0063] The chamber 14 and the annular groove 15 are located inside the inner ring 13. A sand-blocking mesh is installed in the annular groove 15 to intercept concrete raw materials.

[0064] A through groove 19 is formed inside the inner ring 13. The through groove 19 is set as a gap. Multiple through grooves 19 can be selectively formed.

[0065] The nozzle 17 is installed inside the annular groove 15 and the cover plate 18 is installed inside the nozzle 17. The cover plate 18 is set in a semi-circular shape.

[0066] The first connecting pipe 16 is installed inside the chamber 14, and the first connecting pipe 16 connects the water tank and the chamber 14.

[0067] Before using the equipment, the mixing mechanism 9 is used to mix and transport the concrete raw materials. The mixed concrete raw materials enter the material box 11 through the material cylinder 10, and then enter the material pipe 12 through the material box 11. Under the operation of the delivery pump 8, the concrete raw materials in the material pipe 12 are transported to the print head 4. The moving table 2 drives the printing robot 3 and the print head 4 to perform mobile printing work on the guide rail 1.

[0068] Before using the equipment, start the electric valve in the water tank. Water enters the chamber 14 through the first connecting pipe 16 and then flows through the through groove 19 to the inner concave surface of the inner ring 13. At the same time, water is sprayed onto the inner wall of the material pipe 12 through the spray pipe 17 to lubricate the inner ring 13 and the inner wall of the material pipe 12 as much as possible.

[0069] By incorporating a spray nozzle 17, a chamber 14, and a channel 19 within the material pipe 12, water can be sprayed to moisten the pipe wall before concrete is conveyed, thereby reducing the flow resistance of the concrete raw materials. The moist environment delays the adhesion or drying of concrete on the inner wall of the material pipe 12, facilitating subsequent cleaning. Existing equipment, when conveying high-viscosity concrete for extended periods, is prone to rapid drying and blockage of the pipe's inner wall due to a lack of pre-lubrication. Therefore, the material pipe 12, along with the spray nozzle 17 and channel 19 inside, are designed to pre-moisten the pipe wall through water spraying, reducing the risk of blockage.

[0070] The stirring mechanism 9 also includes:

[0071] A disc 902 is installed on the end of the first rotating shaft 901 away from the barrel 10;

[0072] A support rod 909 is provided outside the disc 902. The support rod 909 is inclined and is connected to the scraper 910. The scraper 910 is in contact with the inner wall of the material cylinder 10.

[0073] The scraper 911 and guide plate 916 are installed on the scraper 910. The guide plate 916 is in contact with the bottom of the material cylinder 10. The scraper 911 is set as a flexible scraper 911.

[0074] The groove 912 inside the scraper 910 and the telescopic rod 913 inside the groove 912 are provided. The side of the groove 912 away from the material cylinder 10 is set as an arc surface, and the telescopic rod 913 has an automatic retraction function.

[0075] The telescopic rod 913 has a contact plate 914 on its telescopic end and a contact piece 915 installed on the outside of the contact plate 914. There are three contact plates 914 on both the telescopic rod 913 and the contact plate 914. The three contact plates 914 are connected together. The three contact plates 914 form an arc-shaped edge near the edge of the material cylinder 10. The middle contact plate 914 protrudes slightly. Both the contact plate 914 and the contact piece 915 are made of rubber.

[0076] The connecting plate 903 and the outer frame 906 are installed on the outside of the material cylinder 10;

[0077] The lifting rod 904 and the magnetic plate 905 connected to the telescopic end of the lifting rod 904 are located below the connecting plate 903. The lifting rod 904 is configured as an electric push rod.

[0078] The filter plate 907 is installed inside the outer frame 906 and the shielding assembly 908 is rotatably connected inside the outer frame 906. The filter plate 907 is located inside the channel.

[0079] The process of using mixing unit 9 to mix concrete raw materials:

[0080] The motor is started, driving the first rotating shaft 901, disc 902, support rod 909, scraper 910, scraper blade 911, and guide plate 916 to rotate. The user places the concrete material into the material cylinder 10, and the rotating support rod 909, scraper 910, scraper blade 911, and guide plate 916 mix and stir the concrete material. After stirring, the shielding component 908 is adjusted, and the material cylinder 10 and the material box 11 are connected through the filter plate 907. Driven by the guide plate 916, the concrete material gradually flows through the filter plate 907 into the material box 11, and then enters the material pipe 12 through the material box 11. The concrete material is then transported to the print head 4 by the delivery pump 8.

[0081] During this process, the concrete raw materials come into contact with the filter plate 907, breaking up the air bubbles generated in the concrete raw materials due to stirring, and intercepting large dry powder clumps.

[0082] As the scraper 910 rotates, when the contact plate 914 moves away from the filter plate 907, the contact strip contacts the inner wall of the material cylinder 10, scraping the concrete material on the inner wall of the material cylinder 10. At this time, the telescopic rod 913 is compressed. When the contact plate 914 is in the channel, the telescopic rod 913 returns to its original position, and the contact plate 914 moves slightly away from the groove 912, but the contact plates 914 on both sides are still in the groove 912. The contact strip outside the contact plate 914 begins to scrape the filter plate 907. As the scraper 910 moves the contact plate 914 away from the channel, the telescopic rod 913 is compressed again, and the contact strip contacts the inner wall of the material cylinder 10 again.

[0083] The process of using mixing unit 9 to transport concrete raw materials:

[0084] After mixing, the shielding component 908 is adjusted, and the material cylinder 10 and the material box 11 are connected through the filter plate 907. Driven by the guide plate 916, the concrete raw material gradually flows through the filter plate 907 into the material box 11, and then enters the material pipe 12 through the material box 11. The concrete raw material is then transported to the print head 4 by the delivery pump 8.

[0085] By setting up a mixing mechanism 9, using scrapers 910, scraper blades 911, and guide plates 916, the concrete raw materials are mixed. Existing concrete mixing equipment easily introduces a large number of air bubbles into the concrete raw materials during the mixing process, affecting subsequent printing quality. Therefore, after mixing the concrete raw materials, guide plates 916 are used to drive the material through filter plates 907. During the process of the concrete raw materials passing through filter plates 907, air bubbles generated during mixing are broken and large dry powder clumps are intercepted, thus solving the aforementioned problem.

[0086] By setting up a mixing mechanism 9, a contact plate 914 with a telescopic rod 913 is provided in the groove 912 inside the scraper 910, and a rubber contact piece 915 is used. The contact plate 914 automatically adjusts its extension length according to its position. When the contact plate 914 is away from the channel, the telescopic rod 913 is squeezed and the contact piece 915 contacts the inner wall of the material cylinder 10 to scrape off the attached concrete raw material. When the contact plate 914 rotates to the channel, the telescopic rod 913 springs back to its original position, the contact plate 914 extends slightly outward, and the contact piece 915 rotates to scrape the surface of the filter plate 907 to prevent the filter holes from clogging.

[0087] The shading component 908 includes:

[0088] A second rotating shaft 9081 is rotatably connected inside the outer frame 906, and a shielding box 9082 is connected to the second rotating shaft 9081. The shielding box 9082 is adapted to the outer frame 906.

[0089] A sliding tube 9085 and a contact tube 9086 connected to the inside of the shielding box 9082 are slidably connected to the sliding tube 9085. The contact tube 9086 has a through hole inside.

[0090] Connecting pipe 9084 is installed at the end of moving pipe 9085 away from contact pipe 9086;

[0091] A connecting box 9083 is located at the end of the connecting pipe 9084 away from the moving pipe 9085. Handles are provided on both sides of the connecting box 9083. A second connecting pipe is installed on the outside of the connecting box 9083 and is connected to an external water tank. The side of the connecting box 9083 away from the feed cylinder 10 is made of magnetic material.

[0092] The working process of using the shielding component 908 to clog the filter plate 907:

[0093] Before using the equipment, the worker manually pulls the handle and presses the connecting box 9083. At this time, the shielding box 9082 is in the outer frame 906, and the contact pipe 9086 is in the filter hole of the filter plate 907. The gap between the two is small. When the external water tank is started, water enters the connecting box 9083 through the second connecting pipe, enters the connecting pipe 9084 and the moving pipe 9085 through the connecting box 9083, and enters the contact pipe 9086. The water then flows outward through the through hole of the contact pipe 9086 and contacts the filter hole of the filter plate 907 to lubricate the filter hole.

[0094] The process of adjusting the shielding component 908 away from the filter plate 907:

[0095] After mixing, start the lifting rod 904. The lifting rod 904 drives the magnetic plate 905 to move down. Manually pull the handle away from the channel. The handle moves the connecting box 9083, connecting pipe 9084, moving pipe 9085 and contact pipe 9086. The contact pipe 9086 disengages from the filter plate 907. Manually pull the handle up until the connecting box 9083 and the magnetic plate 905 are attracted and fixed. At this time, the concrete raw material flows through the filter plate 907 into the material box 11.

[0096] By setting up the shielding component 908, a contact pipe 9086 with through holes is inserted into the filter holes of the filter plate 907 before using the equipment to perform water lubrication, reducing the frictional resistance when concrete raw materials pass through. The filter plate 907 is controlled by the movable and fixed connecting box 9083 cooperating with the magnetic plate 905, and by manually adjusting the height and angle of the connecting pipe 9084, the moving pipe 9085, the contact pipe 9086, and the shielding box 9082 to control the closed or open state of the filter plate 907.

[0097] Working principle: Before using the equipment, the worker manually pulls the handle and presses the connecting box 9083. At this time, the shielding box 9082 is in the outer frame 906, and the contact pipe 9086 is in the filter hole of the filter plate 907. The gap between the two is small. When the external water tank is started, water enters the connecting box 9083 through the second connecting pipe, enters the connecting pipe 9084 and the moving pipe 9085 through the connecting box 9083, and enters the contact pipe 9086. Water then flows outward through the through hole of the contact pipe 9086 and contacts the filter hole of the filter plate 907 to lubricate the filter hole.

[0098] When the electric valve in the water tank is activated, water enters the chamber 14 through the first connecting pipe 16, and then flows through the through groove 19 to the concave surface of the inner ring 13. At the same time, water is sprayed onto the inner wall of the feed pipe 12 through the spray pipe 17 to lubricate the inner ring 13 and the inner wall of the feed pipe 12 as much as possible.

[0099] The motor is started, driving the first rotating shaft 901, disc 902, support rod 909, scraper 910, scraper blade 911, and guide plate 916 to rotate. The user places the concrete material into the material cylinder 10, and the rotating support rod 909, scraper 910, scraper blade 911, and guide plate 916 mix and stir the concrete material. After stirring, the shielding component 908 is adjusted, and the material cylinder 10 and the material box 11 are connected through the filter plate 907. Driven by the guide plate 916, the concrete material gradually flows through the filter plate 907 into the material box 11, and then enters the material pipe 12 through the material box 11. The concrete material is then transported to the print head 4 by the delivery pump 8.

[0100] During this process, the concrete raw materials come into contact with the filter plate 907, breaking up the air bubbles generated in the concrete raw materials due to stirring, and intercepting large dry powder clumps.

[0101] As the scraper 910 rotates, when the contact plate 914 moves away from the filter plate 907, the contact strip contacts the inner wall of the material cylinder 10, scraping the concrete material on the inner wall of the material cylinder 10. At this time, the telescopic rod 913 is compressed. When the contact plate 914 is in the channel, the telescopic rod 913 returns to its original position, and the contact plate 914 moves slightly away from the groove 912, but the contact plates 914 on both sides are still in the groove 912. The contact strip outside the contact plate 914 begins to scrape the filter plate 907. As the scraper 910 moves the contact plate 914 away from the channel, the telescopic rod 913 is compressed again, and the contact strip contacts the inner wall of the material cylinder 10 again.

[0102] After mixing, start the lifting rod 904. The lifting rod 904 drives the magnetic plate 905 to move down. Manually pull the handle away from the channel. The handle moves the connecting box 9083, connecting pipe 9084, moving pipe 9085 and contact pipe 9086. The contact pipe 9086 disengages from the filter plate 907. Manually pull the handle up until the connecting box 9083 and the magnetic plate 905 are attracted and fixed. At this time, the mixed concrete raw material flows through the filter plate 907 into the material box 11 and enters the material pipe 12 through the material box 11. Under the operation of the delivery pump 8, the concrete raw material in the material pipe 12 is transported to the print head 4. The moving table 2 drives the printing robot 3 and the print head 4 to perform mobile printing work on the guide rail 1.
