However, in the ceramic 3D printing process, the stability and accuracy of the output material have a decisive impact on the quality of the final product.

[0003] Traditional ceramic 3D printing equipment mostly relies on preset fixed extrusion parameters for material output control, making it inconvenient to monitor and dynamically adjust the actual output in real time. During the printing process, factors such as wear of mechanical parts and fluctuations in ambient temperature and humidity can easily lead to deviations in material linewidth, resulting in uneven printed layer thickness, inconsistent structural strength of ceramic parts, and increased surface roughness. These problems seriously affect the precision and performance of ceramic products and may even cause printing failures, resulting in material waste and low production efficiency. Therefore, an automatic material output detection and adjustment device for 3D printers is proposed. Utility Model Content

A protective cover 15 is arranged on one side of the detection box 10, and a cleaning mechanism is arranged in the middle of the protective cover 15. The mounting rod 5 can be used to fix the detection box 10 to the bottom of the movable base 1. The protective cover 15 protects the detection end of the detection box 10 to prevent dust, splashed ceramic particles and other impurities from adhering to the detection end and affecting the detection effect. The cleaning mechanism can be used to easily clean the surface of the protective cover 15, improving the use effect.

[0026] Mounting rod 5 is fixedly connected to mounting plate 6 and support plate 7 at both ends. Mounting plate 6 facilitates the mounting and fixing of mounting rod 5 to the bottom of movable base 1. Electric push rod 8 is fixedly connected to the top of support plate 7.

When electric push rod 8 is started to control slider 9 to move up and down, the tilt angle of detection box 10 can be adjusted to make detection box 10 correspond to the material output of printing needle 2. Laser is emitted by laser emission source 13 and reflected information is received by laser receiving source 14.

Positioning rubber pillars 22 are symmetrically fixedly connected around the side of the moving seat 1 near the laser emitting source 13. A locking strip 23 is symmetrically fixedly connected around the end of the moving seat 1 near the positioning rubber pillar 22. A slot 24 is opened in the middle of the protective cover 15. The cross-sectional shape of the locking strip 23 is set as a triangle. The locking strip 23 is adapted to the slot 24. The locking strip 23 is set in the middle of the slot 24. One end of the positioning rubber pillar 22 is attached to the inner cavity wall of the protective cover 15. The protective cover 15 is set as Made of transparent acrylic, the mainboard 12 facilitates the reception and control of the laser emitting source 13 and the laser receiving source 14. Information is input into the control box 3 to control the speed of the extrusion motor 4, and to activate the electric push rod 8 to control the slider 9 to move up and down. This allows the detection box 10 to rotate at the bottom of the support plate 7, while simultaneously allowing the slider 9 to slide within the limiting slide frame 11, improving adjustment stability.

[0028] As attached Figure 1 , 2As shown in Figures 3 and 5, the cleaning mechanism includes a motor 16 fixed to one side of the inner cavity of the detection box 10. The output end of the motor 16 has a slot 17. A rotating rod 18 is inserted into the middle of the protective cover 15. One end of the rotating rod 18 is fixedly connected to a plug 19, which is adapted to the slot 17 and is located inside the slot 17. The motor 16 is electrically connected to the main board 12. An arc-shaped rod 21 is fixedly connected to the end of the rotating rod 18 away from the plug 19.

The arc-shaped rod 21 is located on one side of the protective cover 15, and a cleaning brush is located on one side of the arc-shaped rod 21. The cleaning brush and the protective cover... The walls of the protective cover 15 are fitted together, and two limiting plates 20 are respectively set on the inner and outer sides of the protective cover 15. The top of the detection box 10 is fixedly connected to the upright 25, and the middle of the upright 25 is fitted with a baffle 26. One end of the baffle 26 extends to the top of the protective cover 15. The starting motor 16 drives the rotating rod 18 to rotate through the cooperation of the rotating rod 18 and the slot 17, thereby controlling the arc rod 21 to rotate on the surface of the protective cover 15, cleaning the dust and raw material particles attached to the surface of the protective cover 15, improving the use effect, and facilitating installation and combination. The baffle 26 can limit and fix the protective cover 15, improving the stability of the installation of the protective cover 15.

[0029] It is worth noting that by properly adjusting the extrusion speed, pressure and other parameters of the extrusion motor 4, increasing the extrusion speed or pressure will usually increase the output line width, and vice versa.

[0030] The working principle of this utility model is as follows: When in use, the extrusion motor 4 is started to control the raw material to be extruded through the printing needle 2, and the laser is emitted through the laser emission source 13. The reflected signal is received through the laser receiving source 14. The information can be input to the main board 12, and the main board 12 analyzes and processes it to obtain the width of the extruded material. The result generates high and low level signals, which are transmitted to the control box 3 for processing. This allows for automatic control of the speed output of the extrusion motor 4, thereby precisely controlling the extrusion speed and realizing the change of extrusion width. When the extrusion width changes, it automatically adjusts.

[0031] During operation, the motor 16 can be started simultaneously to control the arc rod 21 to rotate and clean the surface of the protective cover 15, so as to prevent dust and raw material particles from adhering to the protective cover 15 and affecting the normal use of the laser emission source 13 and the laser receiving source 14, thereby improving the detection and automatic adjustment effect.

[0032] During installation, the mounting plate 6 is fixed to the movable base 1 by screws passing through the mounting plate 6. The electric push rod 8 is activated to control the slider 9 to move up and down, which can adjust the orientation and tilt angle of the detection box 10, making it convenient to start work until one end of the laser emission source 13 and the laser receiving source 14 corresponds to the extruded material of the printing needle 2, which facilitates installation, debugging and use.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
