DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] Reference Figure 1-5 A full-color 3D printer capable of switching between 3D and plane printing comprises a support base 1, the upper surface of the support base 1 is fixedly connected with a support frame 2, the inner wall of the support frame 2 is fixedly connected with four first electric guide rails 5, the inner wall of each group of first electric guide rails 5 is slidably connected with a second electric guide rail 6, the bottom surface of the support base 1 is fixedly connected with three support legs 3, the bottom surface of each support leg 3 is fixedly connected with a base 4, and by arranging the support legs 3 and the base 4, a good support effect can be provided for the device, so that it can be in a stable working state.

[0018] Specifically, the support base 1: As the basic support component of the entire printer, the support base 1 is designed to bear the weight of all print heads, guide rails and electric drive systems. The stability of the support base is crucial to the printing quality, so its bottom is ensured to be in a stable state during the printing process through the support legs 3 and the base 4 structure. The design of the support legs 3 takes into account the adaptability in different working environments, so that the printer can work smoothly on different floors to avoid the reduction of printing accuracy due to uneven floors.

[0019] Specifically, support frame 2: support frame 2 provides stable support for the upper guide rail system by connecting to the upper surface of the support seat, so that when performing plane and 3D printing tasks, the print head can slide smoothly along the track to ensure precise positioning and printing.

[0020] A flat print head 7 is slidably connected to the inner wall of one of the second electric guide rails 6, and a 3D print head 8 is slidably connected to the inner wall of the other second electric guide rail 6. Two third electric guide rails 13 are fixedly connected to the inner wall of the support base 1, and two display screens 9 are fixedly connected to the outer surface of the support base 1. Four control buttons 10 are fixedly connected to the outer surface of the support base 1. By setting the display screens 9 and the control buttons 10, the operation of the device can be conveniently controlled and viewed, thereby facilitating printing work.

[0021] Specifically, the flat print head is designed to be more lightweight and suitable for flat printing tasks. It has a high material ejection accuracy and can meet the printing needs of common flat materials such as paper and plastic. In actual applications, the flat print head 7 can print accurately along the X-axis and Y-axis through high-speed movement, which is suitable for document printing, image presentation and other scenarios.

[0022] Specifically, the 3D print head is designed with more degrees of freedom and height adjustment functions. It heats and melts materials (such as plastic filaments or resins) and gradually stacks them in layers to form a three-dimensional object. The 3D print head must not only have high-precision vertical and horizontal adjustment capabilities, but also be able to accurately control the injection speed and temperature of the material to ensure seamless quality between printed layers. During use, users can easily switch to 3D printing mode through control buttons and display screens to build three-dimensional models. The modular design of plane and 3D print heads not only saves equipment costs, but also allows users to replace or maintain different print heads according to actual needs. The modular design also facilitates the upgrade and expansion of the equipment, and users can easily upgrade to higher-precision print heads in the future.

[0023] Specifically, display screen 9, the printer is equipped with two display screens, which respectively display the working status of the flat printing mode and the 3D printing mode. The display screen provides real-time feedback, showing the progress of the printing, the remaining time, the current working status and the precise position of the print head. Through the clear graphical interface, the user can easily view the printing process and promptly discover and solve potential problems.

[0024] Specifically, the control button 10: The design of the four control buttons makes the operation easier. The functions of the buttons include starting printing, pausing printing, switching printing modes, and adjusting printing speed. Users can adjust the working mode of the printer through the buttons as needed, and even set shortcut keys for printing parameters to further enhance the operating experience.

[0025] Specifically, intelligent operating system: The printer is also equipped with an intelligent operating system that supports operation through a variety of methods such as touch screen and voice control. There are multiple print preset modes in the operating system. Users only need to select the corresponding print mode, and the system will automatically make corresponding adjustments, further improving work efficiency.

[0026] Specifically, the printer has the intelligent function of automatically detecting environmental factors such as the remaining amount of materials, temperature, and humidity, and can automatically adjust printing parameters according to changes in the external environment. This intelligent adjustment function can effectively reduce the energy consumption of the equipment and improve printing efficiency. By optimizing the control algorithm of the electric guide rail, the printer can reduce power consumption during operation, improve work efficiency, and have a high energy-saving effect.

[0027] The inner walls of the two third electric guide rails 13 are slidably connected to a printing table 14, the inner walls of the planar print head 7 and the inner walls of the 3D print head 8 are slidably connected to a fixed frame 11, and the back of each fixed frame 11 is fixedly connected to a micro servo motor 20. The outer surface of the support frame 2 is fixedly connected to eight reinforcement blocks 12, and the bottom surface of each reinforcement block 12 is fixedly connected to the upper surface of the support seat 1. By setting the reinforcement blocks 12, the stability of the support frame 2 can be further enhanced to avoid separation during use.

[0028] The power output end of each micro servo motor 20 passes through the fixed frame 11 and extends to the inside of the fixed frame 11. The power output end of each micro servo motor 20 is fixedly connected to a threaded rod 21. The end of each threaded rod 21 away from the micro servo motor 20 is rotatably connected to the inner wall of the fixed frame 11. The outer surface of each threaded rod 21 is threadedly connected to a moving platform 15. The outer surface of each micro servo motor 20 is fixedly connected to a protective cover 17. The front side of each protective cover 17 is fixedly connected to the back side of the fixed frame 11. By setting the protective cover 17, the safety of the micro servo motor 20 can be further increased, and the stability effect can also be increased.

[0029] The outer surface of each mobile platform 15 is slidably connected to the inner wall of the fixed frame 11, and the upper surface of each mobile platform 15 is fixedly connected to two electric telescopic rods 23, and the telescopic ends of each set of electric telescopic rods 23 are fixedly connected to a lifting plate 22, and the inner wall of one lifting plate 22 is fixedly connected to two first nozzles 16, and the inner wall of the other lifting plate 22 is fixedly connected to two second nozzles 26. The inner wall of each fixed frame 11 is threadedly connected to two bolts 18, wherein the outer surfaces of two bolts 18 are threadedly connected to the inner wall of the planar print head 7, and the outer surfaces of the other two bolts 18 are threadedly connected to the inner wall of the 3D print head 8. By providing the bolts 18, the fixed frame 11 can be conveniently fixed firmly and prevented from falling off during use.

[0030] The outer surface of each first nozzle 16 and the outer surface of the second nozzle 26 are slidably connected to the inner wall of the movable platform 15, the left side of each movable platform 15 is fixedly connected to a distance measuring block 25, the inner wall of each fixed frame 11 is fixedly connected to a laser distance measuring sensor 24, the top of each first nozzle 16 is fixedly connected to a first sealing gasket 19, and the top of each second nozzle 26 is fixedly connected to a second sealing gasket 27. By providing the first sealing gasket 19 and the second sealing gasket 27, it is possible to conveniently increase the sealing when in contact with the discharge pipe to avoid leakage during use. By providing the first electric The guide rail 5, the second electric guide rail 6 and the third electric guide rail 13, the electric guide rail is a mechatronic device, mainly composed of a track, a slider, a motor and a control unit. The motor drives the slider to perform linear motion on the track, so as to drive the adjustment position to switch the printing mode. By setting a laser ranging sensor 24, the laser ranging sensor 24 calculates the distance by emitting a laser beam and measuring the time from the laser emission to the reflection back. This device usually has high accuracy and can be used to measure the movement of objects within a shorter distance, so that the moving distance can be controlled when the nozzle is replaced.

[0031] Specifically, the connection between the movable platform 15 and the fixed frame 11: the outer surface of each movable platform 15 is connected to the inner wall of the fixed frame 11 by sliding, allowing the movable platform to move horizontally or vertically in the fixed frame. The design of the sliding connection enables the print head and the nozzle to move accurately at the specified position, thereby achieving a high-precision printing process. This sliding connection ensures that the nozzle can slide freely along the predetermined track to meet the needs of different printing modes.

[0032] Specifically, the functions of the electric telescopic rod and the lifting plate are as follows: two electric telescopic rods 23 are fixedly connected to each mobile platform 15, and these telescopic rods control the up and down movement of the lifting plate 22, thereby adjusting the height of the nozzle. Through the precise adjustment of the electric telescopic rods, the position and accuracy of different nozzles in plane and 3D printing can be ensured to meet the requirements of different types of printing tasks.

[0033] Specifically, nozzle design and sealing system: first nozzle 16 and second nozzle 26: the lifting plate 22 on the movable platform 15 is fixedly connected to two first nozzles 16 and two second nozzles 26. The first nozzle is usually used for plane printing, while the second nozzle is used for 3D printing. This design enables the printer to automatically adjust the working state of the nozzle when switching the printing mode, avoiding the tedious manual adjustment during use. The type of nozzle is closely combined with the working mode to ensure that different printing modes can be completed efficiently and accurately. Design of sealing gasket: The top of each first nozzle 16 and the second nozzle 26 is fixedly connected with a sealing gasket (first sealing gasket 19 and second sealing gasket 27). The function of these sealing gaskets is to ensure that the nozzle can be well sealed when in contact with the discharge pipe to avoid material leakage or airflow leakage. The sealing gasket effectively increases the contact sealing between the nozzle and other components, ensures the accurate supply of materials during printing, and avoids printing failure caused by leakage.

[0034] Specifically, the bolt connection and the stability of the fixed frame: the inner wall of the fixed frame 11 is connected to a plurality of bolts 18 through threads, and these bolts are responsible for firmly fixing the planar print head 7 and the 3D print head 8 on the frame. Through the fixing of the bolts, the print head is not easy to loosen or fall off during the working process, ensuring the stability of the printing process. The design of the bolts is simple and efficient, which is convenient for replacement and maintenance when necessary.

[0035] Specifically, the distance measurement system and precision control: a laser distance measurement sensor 24 is fixed on the inner wall of each fixed frame 11, which is used to accurately measure the distance between the nozzle and the working platform. The laser distance measurement sensor accurately measures the position of the object by emitting a laser beam and calculating the time from the laser emission to the reflection back. This system can ensure the height and position accuracy of the print head and avoid the nozzle error affecting the printing quality. Especially when replacing the nozzle, the laser distance measurement system can automatically adjust the height of the nozzle to ensure smooth switching. Distance measurement block 25 and position control: A distance measurement block 25 is fixed on the left side of each mobile platform 15, which is used in conjunction with the laser distance measurement sensor to further enhance position detection and precision control. This design can ensure the precise docking of the nozzle and the platform when switching between plane and 3D printing modes, thereby improving printing accuracy.

[0036] Specifically, electric guide rails and intelligent adjustment: the electric guide rail system, by setting the first electric guide rail 5, the second electric guide rail 6 and the third electric guide rail 13, the printer can achieve precise linear motion, and the electric guide rail system is composed of rails, sliders, motors and control units. The motor drives the slider to perform precise linear motion on the rails, and the control unit adjusts the running path of the print head in real time. This system enables the printer to ensure the working position and printing accuracy of different nozzles through precise guide rail adjustment when switching printing modes. Automatic adjustment and switching: The coordinated work of the electric guide rail system and the telescopic rod enables the device to automatically switch between plane and 3D printing. Whether it is plane printing or three-dimensional printing, the printer can complete complex printing tasks through precise motion and position control. Especially when performing 3D printing, the adjustment of the electric guide rail system and the telescopic rod can accurately control the vertical and horizontal position of the print head to ensure that the material injection of each layer can be accurately aligned.

[0037] Specifically, integrated intelligent control and printing mode switching: intelligent control system, the printer is equipped with a highly integrated control system, including sensors, laser distance measuring devices, distance measuring blocks and other modules, which can provide real-time feedback on the status of the device. Users can easily switch between plane and 3D printing modes, adjust printing parameters, control the position of the print head and the height of the nozzle through the display and control buttons. This system not only improves the convenience of operation, but also provides stable and reliable performance in complex printing processes. Multi-mode switching and fine control: The device can switch working modes according to different printing needs. In plane mode, it mainly performs plane printing, while in 3D mode, three-dimensional printing is performed through precise nozzle height control. This intelligent switching function enables the device to be flexibly used in multiple application scenarios to adapt to different printing needs.

[0038] In addition, a full-color 3D printer capable of switching between 3D and plane printing also includes a feeding system: 3D printing feeding unit: adopts multi-channel feeding design, each channel is independently controlled, and can load a variety of colors and materials (such as metal, plastic, ceramic). Through color mixing and layering control algorithms, accurate color mixing is achieved, and gradient and texture printing are supported.

[0039] Flat printing ink supply unit: It uses CMYK four-color ink cartridges and integrates a high-precision ink flow control chip to ensure the consistency of flat printing quality and color accuracy. The ink cartridges are easy to replace and support a large-capacity continuous ink supply system, which is suitable for long-term printing needs.

[0040] The working principle of the present invention is: when in use, the staff first turns on the power of the first electric guide rail 5, the second electric guide rail 6, the planar print head 7, the 3D print head 8, the display screen 9, the control button 10, the third electric guide rail 13, the micro servo motor 20, the electric telescopic rod 23 and the laser ranging sensor 24, so that they can be in a stable power-on state, and connect them to the external control system for power supply, so as to facilitate the control of printing work. After that, the staff connects different feeding pipes to the planar print head 7 and the 3D print head 8 respectively, so as to facilitate the feeding work. After that, when the staff needs to print, the staff turns on the micro servo motor 20, and the rotation of the micro servo motor 20 can drive the threaded rod 21 to rotate. During the rotation of the threaded rod 21, the moving platform 15 can be driven to move, and the moving platform 15 can drive the lifting plate 22 and the first nozzle 16 or the second nozzle 26 inside to move, and the moving platform 15 can drive the ranging block 25 to move, and the laser ranging sensor 24 can judge the moving distance according to the change of the ranging block 25. After moving to the specified distance, the electric telescopic rod 23 is turned on. The electric telescopic rod 23 can drive the lifting plate 22 and the first nozzle 16 or the second nozzle 26 inside to rise and fall, so that it is convenient to connect with the discharge pipe of the print head, so as to facilitate printing, and the nozzle replacement work can also be carried out according to this method later. Finally, the staff controls the first electric guide rail 5, the second electric guide rail 6, the planar print head 7, the third electric guide rail 13 and the printing table 14 to perform planar printing through the control button 10 and the display screen 9. Conversely, another group of the first electric guide rail 5, the second electric guide rail 6 and the 3D print head 8 can be controlled to perform 3D printing. The first electric guide rail 5 can conveniently drive the second electric guide rail 6, the planar print head 7 and the 3D print head 8 to rise and fall, and the second electric guide rail 6 can conveniently drive the planar print head 7 and the 3D print head 8 to move left and right. At the same time, the third guide rail can drive the printing table 14 to move forward and backward, and switch the planar print head 7 and the 3D print head 8 as needed, so as to perform printing work in different ways.
