Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, specifically to a concrete-based 3D printing quick-drying device. Background Technology

[0002] 3D printing is a high-tech field that has developed rapidly in recent years and has achieved great success in industries such as machinery manufacturing. It has also made progress in fields such as materials and construction. Concrete, the most widely used, most extensive, and most economical building material in contemporary construction, has become a massively used material in modern engineering projects. An increasing number of concrete products are also being produced using 3D printing technology, which involves using concrete as a raw material to create various cement products and construction materials.

[0003] For example, CN215881969U discloses a concrete-based 3D printing quick-drying device that can quickly dry the printed concrete. It can also dry freshly printed concrete with a relatively weak airflow and concrete that has been printed for a longer time with a relatively strong airflow, thereby accelerating the curing efficiency of the underlying concrete.

[0004] The patent describes a method for drying printed concrete by activating a drying mechanism. However, since the drying mechanism moves with the printing mechanism, it can only dry freshly printed workpieces and cannot continuously dry completed workpieces. Utility Model Content

[0005] The purpose of this invention is to provide a concrete-based 3D printing quick-drying device to solve the problem mentioned in the background art that existing 3D printing quick-drying devices are not convenient for air drying concrete.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a concrete-based 3D printing quick-drying device, comprising: a base and a quick-drying mechanism a, wherein a driving mechanism a is mounted on the top of the base, a threaded rod in the driving mechanism a is threadedly connected to a frame, a movable plate is slidably connected inside the frame, and a print head is slidably connected inside the movable plate, characterized in that...

[0007] A workbench is fixedly connected to the top of the base. A quick-drying mechanism a is provided on the top of the workbench. The quick-drying mechanism a includes a flexible hose a that is connected through the top of the workbench. One end of the flexible hose a is connected to a nozzle a. A spring is connected to one side of the bottom of the nozzle a. A hot air blower is connected to the bottom of the workbench through a pipe.

[0008] Specifically, hose a is used to connect the workbench and nozzle a, and to guide the hot airflow generated by the hot air blower into nozzle a, thereby drying the workpiece on the workbench.

[0009] Preferably, a motor is fixedly connected to one side of the workbench, and a drive gear is fixedly connected to the output end of the motor.

[0010] Specifically, the motor is used to drive the drive gear to rotate.

[0011] Preferably, the drive gear is meshed with a driven gear on its outer side, and a limit ring is slidably connected inside the driven gear.

[0012] Specifically, the drive gear meshes with the driven gear and drives the driven gear to rotate.

[0013] Preferably, the bottom of the limiting ring is fixed to the worktable, and the top of the driven gear is fixedly connected to multiple sets of protrusions, which are distributed at equal angles about the central axis of the driven gear.

[0014] Specifically, the limit ring is used to restrict the movement of the driven gear, so that the driven gear can only rotate.

[0015] Preferably, the protrusion is arc-shaped, and a round rod is fixedly connected to one end of the nozzle a.

[0016] Specifically, the round rod is used to connect with nozzle a, and the nozzle a is rotated by the compression of the protrusion.

[0017] Preferably, the two sides of the nozzle a are movably connected to the worktable via a rotating shaft and a bracket.

[0018] Specifically, nozzle a is movably connected to the worktable via a rotating shaft and can rotate.

[0019] Preferably, a connecting ring is fixedly connected to the bottom of the movable plate, and a quick-drying mechanism b is provided inside the connecting ring.

[0020] Specifically, the connecting ring is used to drive multiple sets of quick-drying mechanisms b to move.

[0021] Preferably, the quick-drying mechanism b includes a flexible hose b that is connected through to the outside of the workbench, one end of the flexible hose b is connected through to a connecting ring, and a nozzle b is fixedly connected to the inside of the connecting ring.

[0022] Specifically, hose b is used to transfer hot airflow from the workbench to nozzle b.

[0023] Compared with existing technologies, the advantages of this concrete-based 3D printing quick-drying device are:

[0024] 1. This concrete-based 3D printing quick-drying device, when cooling the printed workpiece, starts a motor to drive the drive gear and driven gear to mesh, thereby causing the driven gear and multiple sets of protrusions to rotate. This rotates the round rod at one end of the nozzle a, causing the multiple sets of round rods and nozzle a to rotate. When nozzle a rotates, it compresses the spring at the bottom. When the protrusion disengages from the nozzle a, the spring returns to its original position and pushes nozzle a to rotate. In this way, multiple sets of nozzles a can rotate back and forth. At this time, a hot air blower can be started, which will input hot air into the worktable and transfer it to multiple sets of nozzles a through the worktable and hose a, thereby increasing the drying range and drying the printed workpiece as a whole. In this way, the concrete workpiece printed in the 3D printing quick-drying device can be quickly dried.

[0025] 2. This concrete-based 3D printing quick-drying device can not only air-dry the workpiece through the quick-drying mechanism a, but also deliver hot air to the connecting ring through the hose b. The hot air is then transmitted to multiple sets of nozzles b through the connecting ring. Since the connecting ring moves up and down with the moving plate, it can drive multiple sets of nozzles b to air-dry the newly printed workpiece, thereby improving the drying efficiency. In this way, the efficiency of the 3D printing quick-drying device in drying workpieces can be improved. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-4 This utility model provides a technical solution: a concrete-based 3D printing quick-drying device, comprising: a base 1 and a quick-drying mechanism a7, a drive mechanism a2 mounted on the top of the base 1, a threaded rod in the drive mechanism a2 threadedly connected to a frame 3, a movable plate 4 slidably connected inside the frame 3, and a print head 5 slidably connected inside the movable plate 4.

[0033] A workbench 9 is fixedly connected to the top of the base 1. A quick-drying mechanism a7 is provided on the top of the workbench 9. The quick-drying mechanism a7 includes a flexible hose a701 that is connected through the top of the workbench 9. One end of the flexible hose a701 is connected to a nozzle a702. A spring 703 is connected to one side of the bottom of the nozzle a702. A hot air blower 10 is connected to the bottom of the workbench 9 through a pipe.

[0034] A motor 704 is fixedly connected to one side of the workbench 9, and a drive gear 705 is fixedly connected to the output end of the motor 704. A driven gear 706 is meshed with the outer side of the drive gear 705, and a limit ring 709 is slidably connected inside the driven gear 706. The bottom of the limit ring 709 is fixed to the workbench 9, and multiple sets of protrusions 707 are fixedly connected to the top of the driven gear 706. The multiple sets of protrusions 707 are distributed at equal angles about the central axis of the driven gear 706. The protrusions 707 are arc-shaped. A round rod 708 is fixedly connected to one end of the nozzle a702. The two sides of the nozzle a702 are movably connected to the workbench 9 through a rotating shaft and a bracket. The drive gear 705 and the driven gear 706 form a meshing transmission structure. An annular groove matching the limit ring 709 is opened at the bottom of the driven gear 706. The driven gear 706 and the limit ring 709 form a sliding structure.

[0035] In practical implementation, this concrete-based 3D printing quick-drying device, when cooling the printed workpiece, drives the motor 704 to rotate the drive gear 705. The drive gear 705 meshes with the driven gear 706, causing the driven gear 706 to rotate. The rotation of the driven gear 706 causes the multiple sets of protrusions 707 at the top to rotate as well, thus actuating the round rod 708 at one end of the nozzle a702. This causes the multiple sets of round rods 708 and the nozzle a702 to rotate. The rotation of the nozzle a702 then stimulates the spring at the bottom. When the protrusion 707 disengages from the nozzle a702, the spring 703 returns to its original position and pushes the nozzle a702 to rotate. In this way, multiple sets of nozzles a702 can rotate back and forth. At this time, the hot air blower 10 can be turned on. The hot air blower 10 will input hot air into the worktable 9 and transfer it to multiple sets of nozzles a702 through the worktable 9 and the hose a701, thereby increasing the drying range and drying the printed workpiece as a whole. In this way, the concrete workpiece printed in the 3D printing quick-drying device can be quickly dried.

[0036] Please see Figures 1-4 A connecting ring 6 is fixedly connected to the bottom of the movable plate 4. A quick-drying mechanism b8 is provided inside the connecting ring 6. The quick-drying mechanism b8 includes a flexible hose b801 that is connected through to the outside of the workbench 9. One end of the flexible hose b801 is connected through to the connecting ring 6. A nozzle b802 is fixedly connected to the inside of the connecting ring 6.

[0037] In practical implementation, this concrete-based 3D printing quick-drying device can not only air-dry the workpiece through the quick-drying mechanism a7, but also deliver hot air to the connecting ring 6 through the hose b801. The hot air is then transmitted to multiple sets of nozzles b802 through the connecting ring 6. Since the connecting ring 6 moves up and down with the moving plate 4, it can drive multiple sets of nozzles b802 to air-dry the newly printed workpiece, thereby improving the air-drying efficiency. In this way, the efficiency of the 3D printing quick-drying device in air-drying workpieces can be improved.

[0038] In summary: When using a concrete-based 3D printing quick-drying device, the print head 5 first prints the workpiece onto the worktable 9. The drive mechanism a2 drives two sets of threaded rods to perform threaded transmission with the frame 3 through a synchronous wheel set, thereby moving the frame 3 and improving the synchronicity of movement on both sides of the frame 3. The drive mechanism b11 drives two sets of threaded rods to perform threaded transmission with the moving plate 4 through a synchronous wheel set, improving the synchronicity of movement at both ends of the moving plate 4. The three drive mechanisms can drive the print head 5 to move in multiple directions, thereby performing printing. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
