Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and in particular to a rubber 3D printing device for replicating molds. Background Technology

[0002] There are various ways to stack thin layers in 3D printing. The most common 3D printer uses fused deposition modeling, also known as fused filament deposition. It involves heating and melting a filament of hot-melt material, which is then extruded through a nozzle with a micro-nozzle. The molten material is ejected from the nozzle and deposited on the production panel or the previous layer of solidified material. It begins to solidify after the temperature drops below the curing temperature. The final product is formed by the accumulation of layers of material.

[0003] However, during the printing process, the heated bed surface of a regular printer will produce debris. Although existing technologies have the function of cleaning debris from the printing platform surface, such as using a motor to drive a brush to sweep debris from the printing platform surface, some sticky substances are difficult to remove with this cleaning method, resulting in poor cleaning effect, thereby reducing the cleanliness of the printing platform and the bottom quality of the product. Utility Model Content

[0004] The problem this invention aims to solve is to provide a 3D printing device for replicating rubber with excellent cleaning effect.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a rubber 3D printing device for replication, including a printer body, a sealing door hinged to the front side of the printer body, a controller fixedly installed on the right side of the printer body, a print head provided on the top of the printer body, an adjustment mechanism provided inside the printer body, a heated bed slidably connected to the inner wall of the printer body, a printing platform slidably connected to the inner wall of the heated bed, and a limiting mechanism provided inside the printer body.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] like Figures 1 to 5 The illustrated 3D printing device for replicating rubber includes a printer body 1. The printer body 1, as the core load-bearing component of the entire device, is made of high-strength aluminum alloy, which has good stability and durability. Its shape is cuboid, providing ample installation space for the internal components.

[0020] A sealing door 2 is installed on the front side of the printer body 1 via a sturdy hinge. The sealing door 2 is made of transparent acrylic sheet, which makes it easy for the operator to observe the printing process. This hinge installation method allows the sealing door 2 to be opened and closed flexibly. When closed, it can effectively prevent external dust and other impurities from entering the printer, ensuring a clean printing environment and thus improving print quality.

[0021] The controller 3 is securely mounted on the right side of the printer body 1. The housing of the controller 3 is made of engineering plastic, which has good insulation and anti-interference properties. Its panel is equipped with an intuitive display screen and operation buttons, which makes it convenient for users to set parameters and control printing. The controller 3 is connected to the various components inside the printer body 1 through a high-precision data cable to ensure stable and fast signal transmission, thereby accurately controlling the entire printing process.

[0022] On the top of the printer body 1, there is a print head 4. The print head 4 is cylindrical in shape and its internal precision structure enables the accurate extrusion of rubber material. The print head 4 is made of a special alloy material that is resistant to high temperature and corrosion, which ensures that it can stably withstand the flow of high-temperature rubber material during long-term printing and is not easily corroded or damaged, thus ensuring the consistency and stability of print quality.

[0023] The printer body 1 has an adjustment mechanism 5 inside.

[0024] The bidirectional motor 501 in the adjustment mechanism 5 is fixedly installed on the inner wall of the printer body 1 by high-strength bolts. Its output end is fixedly connected to the rotating shaft 502. The rotating shaft 502 is made of stainless steel, which has high strength and wear resistance. It rotates with the printer body 1 through a high-precision bearing. The rotation process is smooth and stable, which effectively reduces energy loss and mechanical wear.

[0025] The end of the rotating shaft 502 away from the bidirectional motor 501 is fixedly connected to the driving bevel gear 503. The driving bevel gear 503 and the driven bevel gear 504 are precisely meshed. This gear transmission method has the advantages of high transmission efficiency and stable transmission ratio, and can accurately transmit and change the direction of rotation of the bidirectional motor 501.

[0026] An adjusting screw 505 is tightly fixed to the inner wall of the driven bevel gear 504. The adjusting screw 505 is also made of high-strength alloy steel, and its surface is finely threaded. It rotates with the printer body 1 through a high-quality bearing to ensure flexible rotation.

[0027] An adjusting cylinder 506 is threadedly connected to the outer surface of the adjusting screw 505. The top of the adjusting cylinder 506 is firmly fixed to the bottom of the heated bed 6 by welding. This threaded connection allows the rotation of the adjusting screw 505 to be precisely converted into the linear motion of the adjusting cylinder 506, thereby driving the heated bed 6 to move up and down smoothly. This enables high-precision adjustment of the distance between the heated bed 6 and the print head 4, adapting to the printing needs of rubber products with different thicknesses and precision requirements, ensuring the uniformity and accuracy of the printed layer, and effectively improving the printing quality.

[0028] The printer body 1 has a heated bed 6 slidably connected to its inner wall. The heated bed 6 is made of aluminum alloy with excellent thermal conductivity. Its surface is treated with a special coating, which can make the heat evenly distributed, which helps the rubber material to cure quickly during the printing process, improves printing efficiency and product quality.

[0029] The inner wall of the heated bed 6 is slidably connected to the printing platform 7. The printing platform 7 is made of high-temperature resistant and easy-to-clean glass ceramic. Its surface is smooth and flat, which can ensure the flatness of the bottom surface of the printed product and facilitate cleaning after printing. The sliding connection design between the printing platform 7 and the heated bed 6 allows the printing platform 7 to move smoothly on the heated bed 6, which facilitates operation during the printing process and subsequent disassembly and cleaning.

[0030] The printer body 1 is also equipped with a limiting mechanism 8 inside.

[0031] The limiting rod 801 in the limiting mechanism 8 is made of high-strength stainless steel round rod and is fixedly connected to the bottom surface of the heated bed 6 by welding. A baffle 802 is fixedly connected to the end away from the heated bed 6. The baffle 802 can effectively prevent the elastic element 803 from slipping off the limiting rod 801.

[0032] An elastic element 803 is sleeved on the outer surface of the limiting rod 801. The elastic element 803 is a high-elasticity spring. One end of the spring is fixedly connected to the outer surface of the baffle 802, and the other end is fixedly connected to a pressure plate 804. The pressure plate 804 is a rectangular metal plate, and a limiting plate 805 is fixedly connected to its outer surface. The limiting plate 805 is long and is inserted into the interior of the heated bed 6.

[0033] Under normal conditions, the elastic force of the elastic element 803 keeps the limiting plate 805 tightly inserted into the heated bed 6, reliably limiting the printing platform 7 and ensuring that it will not shift during printing, thus guaranteeing printing accuracy. When the printing platform 7 needs cleaning, the pressure plate 804 is pressed down against the elastic force of the elastic element 803, which drives the limiting plate 805 out of the heated bed 6, releasing the limiting of the printing platform 7. At this time, pulling the printing platform 7 forward can easily disengage it from the heated bed 6, making it easy to remove for thorough cleaning. After cleaning, the printing platform 7 is placed back into the heated bed 6, and the pressure plate 804 is released. Under the action of the elastic force of the elastic element 803, the limiting plate 805 can quickly re-insert into the heated bed 6, stably limiting the printing platform 7 again, ensuring that the printing device can operate continuously and stably, and improving the efficiency and quality of printing work.

[0034] Working Principle: In use, the bidirectional motor 501 is started by the controller 3. The bidirectional motor 501 drives the rotating shaft 502 to rotate, and the driving bevel gear 503 on the rotating shaft 502 rotates accordingly. This meshes with and drives the driven bevel gear 504 to rotate, causing the adjusting screw 505 to rotate. Since the adjusting cylinder 506 is fixed to the bottom of the heated bed 6 and threadedly connected to the adjusting screw 505, the rotation of the adjusting screw 505 causes the adjusting cylinder 506 to move the heated bed 6 up and down, thereby achieving precise adjustment of the distance between the heated bed 6 and the print head 4. The system can be adjusted to suit different printing needs. When it is necessary to clean the stubborn sticky substances on the printing platform 7, the pressure plate 804 is pressed down by the elastic force of the elastic element 803, which drives the limiting plate 805 to disengage from the heated bed 6 and release the limiting of the printing platform 7. At this time, the printing platform 7 can be pulled forward to disengage from the heated bed 6, making it easy to take it out for cleaning. After cleaning, the printing platform 7 is put back into the heated bed 6, the pressure plate 804 is released, and the limiting plate 805 is reinserted into the heated bed 6 under the action of the elastic element 803 to limit the printing platform 7.
