Description

Technical Field

[0001] This utility model relates to the field of automotive prototype processing technology, specifically a drying mechanism for 3D printed automotive prototype models. Background Technology

[0002] A car prototype is a physical model made during the design and development of a car. It can intuitively show the appearance, structure and some functions of the car. Using 3D printing technology, high-precision and complex-shaped samples can be produced quickly. After 3D printing, the car prototype usually needs to be dried by a drying machine to stabilize its performance.

[0003] Existing 3D printed car prototype drying mechanisms typically use a fan to draw in outside air. As the outside air flows over the electric heating wire, its temperature rises, and then the heated air is blown onto the 3D printed model to dry the car prototype.

[0004] Existing drying mechanisms for 3D printed car prototype models have the following problems: during the drying process, the air blown by the fan is usually at a fixed angle, resulting in uneven drying of the car prototype model and a decrease in drying efficiency. To address this, we propose a new drying mechanism for 3D printed car prototype models. Utility Model Content

The lower side of the outer surface of the sliding column is provided with a fixed rod that is evenly distributed. The guide plate has a limiting groove on the side near the sliding column. The front and rear ends of the fixed rod are slidably connected to the interior of the adjacent limiting groove. During the drying process of the car prototype model using the drying mechanism, the direction of the airflow blown by the fan is changed by adjusting the mechanism, so that the drying of the car prototype model is uniform and the drying efficiency of the car prototype model is improved.

[0008] Furthermore, it also includes a microcontroller, which is fixedly connected to the front side of the housing.

The lower end of the telescopic shaft of the electric push rod is fixedly connected to the upper end of the slide column. The input end of the electric push rod is electrically connected to the output end of the microcontroller, which facilitates the normal operation of the adjustment mechanism.

[0010] Furthermore, the adjustment mechanism also includes a rib groove and a rib. The inner wall of the slide is provided with a rib groove, and the upper side of the outer surface of the slide column is provided with a rib. The rib is slidably connected to the inside of the rib groove, which facilitates the sliding limit of the slide column.

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.

[0021] Please see Figure 1-3This embodiment provides a technical solution: a drying mechanism for a 3D printed car prototype model, including a housing 1, a 3D printer 4 on the left side of the bottom wall of the housing 1, an isolation plate 13 on the right side of the interior of the housing 1, an adjustment mechanism 3, and a microcontroller 2. The microcontroller 2 is fixedly connected to the front side of the housing 1, and its input is electrically connected to an external power source. The input of the 3D printer 4 is electrically connected to the output of the microcontroller 2. A fan 5 is installed in the mounting port on the right side of the housing 1, and evenly distributed exhaust holes 6 are opened on the rear side of the housing 1. The input of the fan 5 is electrically connected to the output of the microcontroller 2. A fixing frame 7 is provided on the right side wall of the housing 1, and an electric heating wire 8 is installed inside the fixing frame 7. The electric heating wire 8 is distributed in an S-shape, and its input is electrically connected to the output of the microcontroller 2. A cover 1 is rotatably connected to the opening on the upper surface of the housing 1 via a rotating shaft 9. 0. A glass observation window 11 is provided in the groove on the outer surface of the box cover 10. A handle 12 is provided on the front side of the box cover 10. When printing a car prototype model, the staff inputs the data into the microcontroller 2, and then controls the 3D printer 4 to work through the microcontroller 2 to 3D print the car prototype model. After printing, the fan 5 and the electric heating wire 8 are turned on. The fan 5 draws outside air into the outer shell 1. The airflow temperature rises when it passes through the electric heating wire 8. The heated airflow is blown onto the car prototype model by the guide plate 32 to dry the car prototype model. The humid airflow is discharged from the outer shell 1 through the exhaust hole 6. During the printing process, the staff can watch the printing process through the glass observation window 11. After drying, the handle 12 drives the box cover 10 to rotate around the pivot 9, thereby opening the box cover 10 and then taking out the car prototype model.

[0022] Adjustment mechanism 3 includes a rotating rod 31, a guide plate 32, a sliding column 33, a fixed rod 34, and a limiting groove 35. The rotating rod 31 is rotatably connected to a slot on the left side of the isolation plate 13. The guide plate 32 is fixedly fitted onto the outer surface of each rotating rod 31. A sliding opening is provided on the upper surface of the isolation plate 13, and a sliding column 33 is slidably connected inside the opening. Fixed rods 34 are evenly distributed on the lower side of the outer surface of the sliding column 33. Limiting grooves 35 are provided on the side of the guide plate 32 near the sliding column 33. The front and rear ends of the fixed rod 34 are slidably connected to the interior of adjacent limiting grooves 35. Adjustment mechanism 3 also includes an electric push rod 38. An electric push rod 38 is provided on the top wall of the outer casing 1. The lower end of the telescopic shaft of the electric push rod 38 is fixedly connected to the upper end of the sliding column 33. The input end of the push rod 38 is electrically connected to the output end of the microcontroller 2. The adjustment mechanism 3 also includes a rib groove 36 and a rib 37. The inner wall of the sliding mouth is provided with a rib groove 36, and the upper side of the outer surface of the sliding column 33 is provided with a rib 37. The rib 37 is slidably connected to the inside of the rib groove 36. During the drying process, the electric push rod 38 is turned on. Under the restriction of the rib groove 36 and the rib 37, the telescopic shaft of the electric push rod 38 drives the sliding column 33 to move up and down. While the sliding column 33 moves up and down, the fixed rod 34 moves along with it. Due to the existence of the limiting groove 35, the fixed rod 34 slides in the limiting groove 35 while moving up and down, causing the guide plate 32 to rotate around the rotating rod 31 as the center, thereby changing the direction of the airflow, resulting in uniform drying of the car prototype model and improving the drying efficiency of the car prototype model.

[0023] The working principle of the 3D printed car prototype drying mechanism provided by this utility model is as follows: When printing a car prototype model, the operator inputs the data into the microcontroller 2, and then controls the 3D printer 4 to work through the microcontroller 2 to 3D print the car prototype model. After printing, the fan 5 and the electric heating wire 8 are turned on. The fan 5 draws outside air into the outer shell 1. The airflow temperature rises when passing through the electric heating wire 8. The heated airflow is blown onto the car prototype model by the guide plate 32 to dry the car prototype model. The humid airflow is discharged from the outer shell 1 through the exhaust port 6. During the drying process, the electric push rod 38 is turned on, and the rib groove 36 and ribs are dried. Under the constraint of 37, the telescopic shaft of the electric push rod 38 drives the slide column 33 to move up and down. While the slide column 33 moves up and down, the fixed rod 34 moves along with it. Due to the presence of the limiting groove 35, the fixed rod 34 slides in the limiting groove 35 while moving up and down, causing the guide plate 32 to rotate around the rotating rod 31, thereby changing the direction of airflow and making the drying of the car prototype model more uniform, thus improving the drying efficiency of the car prototype model. During the printing process, the staff can watch the printing process through the glass observation window 11. After drying, the handle 12 drives the box cover 10 to rotate around the rotating shaft 9, thereby opening the box cover 10 and then taking out the car prototype model.

[0024] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an Ardu i no series, the 3D printer 4 can be a Prusa i 3MK2, and the fan 5 can be an SF axial flow fan. The microcontroller 2 controls the operation of the electric push rod 38, the 3D printer 4, the fan 5, and the electric heating wire 8 using methods commonly used in the prior art.
