Description

Technical Field

[0001] This utility model relates to the field of sand mold blank technology, and more specifically, to an online cleaning device for the surface of sand mold blanks. Background Technology

[0002] With the widespread application of 3D printing technology in manufacturing, it has also made significant progress in the field of sand mold manufacturing. 3D printed sand molds have advantages such as strong ability to form complex shapes, high degree of design freedom, and short production cycle, which can meet the personalized and precision requirements of more and more high-end casting products for sand molds. However, after the 3D printed sand mold blank is formed, the surface cleaning problem has become a key link restricting the improvement of production efficiency and product quality.

[0003] A search revealed that Chinese patent CN212884878U discloses a 3D printed sand mold surface cleaning device. This device addresses the safety issues of existing technologies, such as unsafe working environments, sand scattering everywhere when compressed air blows away sand, requiring operators to wear full protective gear to avoid eye injury, and large areas of sand settling on the ground requiring manual cleaning and recovery, resulting in low efficiency. Compressed air is also used, but the cleaning area is limited, requiring manual handling to blow the entire mold, leading to high labor intensity. This new device completely covers the 3D printed sand mold as sand particles fall from above, achieving a thorough cleaning effect through continuous flushing. This transforms the traditional point-line-to-surface cleaning method into a surface-line-to-body method, significantly improving cleaning efficiency and ensuring effective cleaning.

[0004] However, the cleaning device varies in its control of the cleaning tool and selection of the cleaning path when cleaning the sand mold blank. This can easily lead to some areas being incompletely cleaned while others are over-cleaned, resulting in inconsistent surface quality of the sand mold blank. This affects the precision of subsequent casting processes and the quality of the finished product. In addition, some automatic cleaning devices are not easy to adjust according to sand mold blanks of different sizes, which affects the cleaning effect. Utility Model Content

[0005] In order to overcome the problems and defects in the prior art, this utility model provides an online cleaning device for the surface of sand mold blanks to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an online cleaning device for the surface of a sand mold blank, including a workbench, a movable cleaning mechanism on the top of the workbench, and a dust collection mechanism on the bottom of the workbench;

[0007] The mobile cleaning mechanism includes a support column fixed to the top of the workbench. A top beam is fixedly connected to the top of the support column, and a first motor is fixedly installed on the top of the top beam. A rotating bushing is fixedly connected to the output end of the first motor. A connecting rod is slidably connected inside the rotating bushing. An electric slide is fixedly connected to the bottom of the connecting rod. A fixed frame is slidably connected to the bottom of the electric slide. A second motor is fixedly installed on the top of the inner wall of the fixed frame. A fixed plate is fixedly connected to the bottom of the fixed frame. A rotating shaft is fixedly connected to the output end of the second motor. A cleaning disc is fixedly connected to the bottom of the rotating shaft. Cleaning bristles are fixedly installed at the bottom of the cleaning disc. An adjustment mechanism is provided between the rotating bushing and the connecting rod.

[0008] Preferably, the adjusting mechanism includes a threaded groove, which is formed on one side of the connecting rod, and a threaded hole is formed on one side surface of the rotating bushing.

[0009] Preferably, both the threaded groove and the threaded hole are threaded with bolts, and the number of threaded grooves is set to multiple.

[0010] Preferably, the dust collection mechanism includes a dust collection box, which is installed at the bottom of the workbench. A side plate is fixedly connected to the top of the dust collection box, and the top of the side plate passes through the workbench and extends to the top of the workbench.

[0011] Preferably, a dust collection groove is formed on one side surface of the side plate, and a connecting groove is formed on the bottom surface of the inner wall of the dust collection groove.

[0012] Preferably, an exhaust fan is fixedly installed on the rear side of the dust collection box, and one end of the exhaust fan passes through the dust collection box and extends into the interior of the dust collection box.

[0013] Preferably, a dustproof net is fixedly installed on the inner wall of the dust collection box near the exhaust fan, and a dust discharge pipe is fixedly connected to one side of the dust collection box, with a valve installed inside the dust discharge pipe.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. By setting up a moving cleaning mechanism and an adjustment mechanism, the first motor can quickly adjust the cleaning disc in the vertical direction. Combined with the movement of the electric slide table in the horizontal direction, it can quickly and accurately position the cleaning disc at any position on the surface of the sand mold blank. There is no need for frequent manual adjustment of the cleaning tool position, which greatly shortens the preparation time before cleaning and thus improves the overall cleaning efficiency. The electric slide table and the motor-driven rotating shaft can provide stable and precise motion control, so that the cleaning path and force of the cleaning disc on the surface of the sand mold blank are highly consistent each time. This avoids the problem of incomplete or over-cleaning of some areas due to differences in manual operation, and ensures the uniformity and stability of the cleaning quality of each sand mold blank surface. By using bolts with threaded grooves at different positions, the height of the connecting rod in the rotating bushing can be adjusted, thereby realizing the flexible change of the height of the cleaning disc, which can adapt to the cleaning work of sand mold blanks of various heights and sizes.

[0016] 2. By incorporating a dust collection mechanism, a powerful negative pressure is generated during operation using an exhaust fan. The dust and impurities generated during the cleaning process are promptly drawn into the dust collection box through the dust collection grooves and connecting grooves on the side panels. This prevents dust from spreading and flying on the workbench, effectively improving the environmental quality of the work site and reducing the harm of dust to the health of operators. The dust collection box also prevents these pollutants from being directly emitted into the atmosphere, reducing environmental pollution and meeting the requirements of modern environmentally friendly production.

[0025] The mobile cleaning mechanism includes a support column 2, which is fixed to the top of the workbench 1. A top beam 3 is fixedly connected to the top of the support column 2. A first motor 4 is fixedly installed on the top of the top beam 3. A rotating bushing 5 is fixedly connected to the output end of the first motor 4. A connecting rod 6 is slidably connected inside the rotating bushing 5. An electric slide table 7 is fixedly connected to the bottom of the connecting rod 6. A fixed frame 8 is slidably connected to the bottom of the electric slide table 7. A second motor 9 is fixedly installed on the top of the inner wall of the fixed frame 8. A fixed plate 10 is fixedly connected to the bottom of the fixed frame 8. A rotating shaft 11 is fixedly connected to the output end of the second motor 9. A cleaning disc 12 is fixedly connected to the bottom of the rotating shaft 11. A cleaning brush bristles 13 are fixedly installed at the bottom of the cleaning disc 12. An adjustment mechanism is provided between the rotating bushing 5 and the connecting rod 6.

[0026] As attached Figure 2 , 4 As shown, the adjustment mechanism includes a threaded groove 14, which is opened on one side of the connecting rod 6. A threaded hole 15 is opened on one side of the rotating bushing 5. Bolts 16 are threadedly connected inside the threaded groove 14 and the threaded hole 15. The number of threaded grooves 14 is set to multiple, which facilitates the adjustment of the height of the cleaning disc 12 and the cleaning bristles 13.

[0027] As attached Figure 1 , 2As shown in Figure 5, the dust collection mechanism includes a dust collection box 17, which is installed at the bottom of the workbench 1. A side plate 18 is fixedly connected to the top of the dust collection box 17. The top of the side plate 18 passes through the workbench 1 and extends to the top of the workbench 1. A dust collection groove 19 is opened on one side surface of the side plate 18. A connecting groove 20 is opened on the bottom surface of the inner wall of the dust collection groove 19. An exhaust fan 21 is fixedly installed on the rear side of the dust collection box 17. One end of the exhaust fan 21 passes through the dust collection box 17 and extends into the interior of the dust collection box 17. A dustproof net 23 is fixedly installed on the inner wall of the dust collection box 17 near the exhaust fan 21. A dust discharge pipe 22 is fixedly connected to one side of the dust collection box 17. A valve 24 is installed inside the dust discharge pipe 22 to facilitate the collection of dust during the cleaning process and prevent dust from spreading and affecting the health of the staff.

[0028] The working principle of this utility model is as follows: When cleaning the sand mold blank, the frame structure formed by the support column 2 and the top beam 3 first provides support for other components. The first motor 4 starts, and its output end drives the rotating bushing 5 to rotate. The connecting rod 6, which is slidably connected inside the rotating bushing 5, can slide up and down within a certain range. The relative position of the connecting rod 6 within the rotating bushing 5 can be adjusted by the adjustment mechanism. The threaded groove 14 on one side of the connecting rod 6 corresponds to the threaded hole 15 on one side of the rotating bushing 5. When it is necessary to adjust the height of the connecting rod 6, the height of the connecting rod 6 within the rotating bushing 5 can be adjusted by screwing the bolt 16 into the threaded groove 14 at different positions. Multiple heights can be set to accommodate the cleaning needs of sand mold blanks of different sizes. After the height is adjusted, the electric slide table 7 starts working. The fixed frame 8, which is slidably connected to the bottom of the electric slide table 7, can move horizontally under the drive of the electric slide table 7, thereby moving the cleaning disc 12 at the bottom of the fixed frame 8 to a suitable position on the surface of the sand mold blank. Then, the second motor 9 at the top of the inner wall of the fixed frame 8 starts, and its output end drives the rotating shaft 11 to rotate. The cleaning disc 12, which is fixedly connected to the bottom of the rotating shaft 11, rotates accordingly. The cleaning bristles 13, which are fixedly installed at the bottom of the cleaning disc 12, rotate and sweep the surface of the sand mold blank. Through the friction of the bristles, the impurities, dust and other attachments on the surface of the sand mold blank are removed.

[0029] When the cleaning disc 12 cleans the surface of the sand mold blank, the generated dust and impurities will fly up. At this time, the exhaust fan 21 will start. One end of the exhaust fan 21 passes through the dust collection box 17 and extends into the dust collection box 17. The operation of the exhaust fan 21 generates negative pressure. Under the action of negative pressure, the air above the workbench 1 and the dust and impurities generated during cleaning are sucked into the dust collection box 17 through the dust suction groove 19 and the connecting groove 20 on the side plate 18. A dustproof net 23 is fixedly installed on the inner wall of the dust collection box 17 near the exhaust fan 21. The dustproof net 23 can prevent dust from entering the exhaust fan 21 and play a protective role for the exhaust fan 21. The dust and impurities sucked into the dust collection box 17 will settle and accumulate in the dust collection box 17. When it is necessary to clean the dust collection box 17, the valve 24 installed inside the dust discharge pipe 22 fixedly connected to one side of the dust collection box 17 can be opened to discharge the dust and impurities collected in the dust collection box 17.

[0030] In conclusion, the above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
