Description

Technical Field

[0001] The utility model relates to the technical field of constant temperature control, and in particular to a novel and compact constant temperature controller for a light-curing 3D printer. Background Art

[0002] Many of today’s box sealing equipment and machines have high requirements for constant temperature to ensure that the equipment can perfectly perform its functions. For example, light-curing 3D printers need to operate at a constant temperature to ensure the high accuracy of the printed model while avoiding damage to the model. In addition, drying materials such as PLA, PETG, and ABS also needs to be carried out in a constant temperature environment to ensure the quality and performance of the materials.

[0003] Printing failure of a light-curing 3D printer is affected by temperature: a temperature below the curing point of the resin will make the resin viscous and reduce fluidity, thereby slowing down the curing speed and possibly causing problems with the printed model, such as breakage or delamination. On the contrary, too high a temperature may cause the printing support and model to become soft or even deformed;

[0004] When the FDM carton sealing printer needs to maintain a constant internal temperature during printing, such as when printing ABS materials, temperature control is crucial. By maintaining a suitable temperature, it can ensure that the ABS material adheres well to the printing platform, avoiding poor adhesion or misalignment, thereby ensuring printing quality and stability;

[0005] 3D printer consumables will become relatively moist due to being exposed to the air for a period of time, which will cause problems such as brushing, rough surface, and low strength in the printed models during printing.

[0006] Based on the above-mentioned problems, a new compact constant temperature controller for light-curing 3D printer is designed, which can accurately control the temperature in a small space. Utility Model Content

[0027] Example

[0028] See also Figure 1 to Figure 5 In this embodiment, a novel and compact constant temperature controller for a light-curing 3D printer is provided, comprising a housing, the housing being composed of a housing 1 and a front cover 2. The front cover 2 is installed at the front end of the housing 1, and the front cover 2 and the housing 1 form a housing structure of the entire controller, and other structural components are installed inside the housing to form protection;

[0029] An air intake plate 3 is arranged at the front side of the shell, and an air blowing plate 4 is arranged at the top of the shell. External gas is sucked into the shell from the air intake plate 3, and then discharged from the air blowing plate 4 after being heated, forming a cycle. Ventilation grooves 12 are arranged on the air blowing plate 4 and the air intake plate 3, and the venting grooves 12 are used to discharge gas.

[0030] A control panel 5 is arranged below the air intake plate 3 on the front side of the housing. A digital tube display screen 51 is installed on the control panel 5. The digital tube display screen 51 is used to display the temperature. In addition, a heat dissipation indicator light 53 and a heating indicator light 54 are arranged on one side of the digital tube display screen 51. When the target temperature is lower than the ambient temperature, the heat dissipation indicator light 53 lights up, the heating block 10 does not heat, the turbo fan 8 rotates to discharge air, and after the temperature drops to the same level as the target temperature, the temperature is kept constant, and the heating indicator light 54 indicates the working condition during heating.

[0031] In addition, a temperature control key 52 is provided below the digital tube display screen 51. The temperature control key 52 includes a temperature control-key and a temperature control+key, which are used to adjust the heating temperature of the controller;

[0032] The bottom of the housing is provided with a control main board 7, which is used to control the entire controller to realize automatic operation. Moreover, a thermistor 11 is electrically connected to the control main board 7. The thermistor 11 is located at the vent groove 12 of the air intake plate 3. The thermistor 11 can measure the temperature of the external gas entering through the air intake plate 3, and then judge the external ambient temperature. If the ambient temperature is lower than the set temperature, heating continues. If the set temperature is reached, the temperature is kept constant. The thermistor 11 can be a thermistor.

[0033] A turbo fan 8 is arranged above the control main board 7 in the housing, and a heating block 10 is arranged above the turbo fan 8. The turbo fan 8 draws in external gas from the air intake plate 3, and then the gas is heated by the heating block 10, becomes hot gas, and is discharged from the air blowing plate 4.

[0034] The turbofan 8 is arranged corresponding to the position of the air intake plate 3 to facilitate the entry of gas. An inner magnet 9 is embedded on the inner wall of the front cover plate 2 (in the attached figure, the inner magnet 9 is located at the turbofan 8 because the front cover plate 2 is disassembled). Correspondingly, an outer magnet is arranged on the top of the air intake plate 3, and the two are attracted to each other. The bottom of the air intake plate 3 is installed in the front cover plate 2, and the top is fixed by the mutual attraction between the outer magnet and the inner magnet 9, which is convenient for disassembly and cleaning. In addition, a filter cotton is also arranged inside the air intake plate 3, and the filter cotton can filter the external gas to prevent debris or dust from entering the shell;

[0035] The controller is powered by an external power supply. A power interface 6 is provided on the side wall of the box body 1 at a position corresponding to the control main board 7, and can be connected to an external power plug to realize power supply.

[0036] When the controller of the utility model is working, the + and - keys in the temperature control key 52 are used to set the required temperature. The control main board 7 is responsible for regulating the heating block 10 for heating, and the heating indicator light 54 will light up. At the same time, the turbo fan 8 quickly dissipates the heat energy generated by the heating block 10, and detects the ambient temperature through the thermistor 11. Once the set target temperature is reached, the control main board 7 controls the heating block 10 to start and stop heating and automatically maintain a constant temperature state.

[0037] The controller of the utility model has wide applications and good practicality. It can be used on FDM3D box sealing printers to solve the problems of poor adhesion or misalignment and improve the printing success rate. It can also be used to dry 3D consumables to solve the problems of wire drawing, rough surface, low strength, etc. caused by the consumables being exposed to humid air during printing.

[0038] The controller of the utility model utilizes the control main board 7 to control the heating of the heating block 10, and releases the heat into the surrounding environment through the turbo fan 8, so as to realize the constant temperature control of a small range of environment. The thermistor 11 can provide accurate temperature detection data, effectively improve the problem of printing failure of the light-curing 3D printer due to temperature fluctuation, and can stabilize the printing environment within a constant and suitable temperature range, so as to ensure that each printed model can achieve the expected effect and avoid the adverse effects caused by temperature fluctuation.
