Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, and in particular to a polishing and dust collection device for 3D printing post-processing. Background Technology

[0002] 3D printing technology is a rapid prototyping additive manufacturing technology that uses the fused deposition modeling method to build products by stacking materials layer by layer. Because 3D printed products have a rough surface, the surface of the product usually needs to be polished to improve the product quality. The polishing process generates a lot of dust and debris, which not only pollutes the working environment and affects the polishing operation, but also harms the health of the operators.

[0003] For example, Chinese utility model patent (CN220296762U) discloses a post-processing polishing device for 3D printed products, which states that: "When 3D printed products are polished, the dust generated is sucked into the dust exhaust channel through the air source, reducing the dust inside the polishing area, and under the action of the filter, the dust can be prevented from being discharged into the air and polluting the working environment again."

[0004] The aforementioned patent filters dust from the airflow through a filter section, but the filter section lacks a self-cleaning function, leading to frequent clogging. This requires frequent manual cleaning and maintenance by staff, and maintenance usually requires shutting down the equipment, which in turn affects the polishing efficiency. Therefore, this application proposes a polishing dust collection device for 3D printing post-processing. Utility Model Content

Through the overall structural design, when using a dust collection fan in conjunction with an air pipe, hood, ventilation tube, and filter to collect and filter dust, the drive guide frame can be driven to move back and forth to facilitate the automatic scraping and cleaning of the filter using a dust brush frame. This effectively alleviates and reduces the frequency of filter clogging, thereby reducing the number of times workers need to manually clean the filter and minimizing the impact on sanding efficiency.

[0025] To solve this technical problem, this utility model provides a 3D printing post-processing polishing and dust collection device, which is applied to the polishing of 3D printed products;

[0026] The system includes a chassis 1, an inner support frame 3 installed inside the chassis 1, a perforated operating plate 4 and a shelf 5 fixed inside the inner support frame 3, a dust collector 2 installed at the top of the chassis 1, a base frame 10 fixed inside the chassis 1 and at the bottom of the inner support frame 3, a support shaft 20 rotatably connected to one end of the base frame 10, a baffle 21 fixed to the outside of the support shaft 20, the baffle 21 being in contact with the base frame 10, a guide post 11 and a reciprocating screw 12 respectively provided at the other end of the base frame 10, both the guide post 11 and the reciprocating screw 12 being fixed to the chassis 1, a pusher frame 13 slidably connected to the outside of the guide post 11, a dust brush frame 18 fixed to the end of the pusher frame 13 away from the guide post 11, and a dust collection box 26 slidably connected to the inside of the chassis 1 and at the bottom of the baffle 21, the dust collection box 26 being in contact with the base frame 10.

[0027] The 3D printing post-processing grinding and dust removal device provided by this utility model, through the overall structural design, facilitates the automatic scraping and cleaning of the filter element 9, thereby effectively alleviating and reducing the frequency of clogging of the filter element 9, thus reducing the number of manual cleanings by staff and the impact on grinding efficiency.

[0028] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] Example 1:

[0031] Please refer to Figure 1-5 A 3D printing post-processing polishing and dust collection device includes a housing 1, an inner support frame 3 installed inside the housing 1, and a hollow operation plate 4 and a placement plate 5 fixed inside the inner support frame 3 respectively. When polishing at the upper end of the hollow operation plate 4, the dust can easily fall down through the hollow operation plate 4, while the polishing tools are placed at the upper end of the placement plate 5. In order to facilitate the collection of dust through the hollow operation plate 4, a dust collection fan 2 is installed at the upper end of the housing 1, and a base frame 10 is fixed inside the housing 1 and at the lower end of the inner support frame 3.

[0032] Specifically, the suction port of the vacuum cleaner 2 is fixedly connected to an air pipe 6. The end of the air pipe 6 away from the vacuum cleaner 2 is fixed to a hood 7. The hood 7 is located inside the housing 1 and fixed to the housing 1. The end of the hood 7 away from the air pipe 6 is fixed to a ventilation tube 8. The outer side of the end of the ventilation tube 8 away from the hood 7 is in contact with the base frame 10. The inner side of the end of the ventilation tube 8 away from the hood 7 is fixed to a filter element 9. The air pipe 6, the hood 7, and the ventilation tube 8 are connected. The end of the dust brush holder 18 away from the pusher frame 13 is in contact with the filter element 9.

[0033] To achieve automated cleaning of the filter element 9 and effectively alleviate and reduce the clogging frequency of the filter element 9, a support shaft 20 is rotatably connected to one end of the base frame 10, and a guide post 11 and a reciprocating screw 12 are respectively provided at the other end of the base frame 10. The guide post 11 and the reciprocating screw 12 are both fixed to the housing 1. A pusher frame 13 is slidably connected to the outside of the guide post 11. A dust brush frame 18 is fixed to the end of the pusher frame 13 away from the guide post 11. A hollow screw cylinder 14 is rotatably connected to the inside of the pusher frame 13 and located outside the reciprocating screw 12. The inside of the hollow screw cylinder 14 is threadedly connected to the reciprocating screw 12. A first spur gear 15 is fixed to the outside of the hollow screw cylinder 14. A first motor 16 is fixed to the inside of the pusher frame 13 and located outside the first spur gear 15. A second spur gear 17 is fixed to the output end of the first motor 16. The second spur gear 17 is meshed with the first spur gear 15. A vibration motor 19 is installed between the pusher frame 13 and the dust brush frame 18.

[0034] In order to collect the dust falling from the filter element 9, a baffle 21 is fixed on the outside of the support shaft 20. The baffle 21 is in contact with the base frame 10. When the control shaft 20 rotates and drives the baffle 21 to flip, in order to facilitate the collection of dust falling from the baffle 21, a dust collection box 26 is slidably connected to the inside of the housing 1 and located at the lower end of the baffle 21. The dust collection box 26 is in contact with the base frame 10.

[0035] Specifically, in order to facilitate the rotation of the support shaft 20 to drive the baffle 21 to flip, thereby facilitating the downward discharge of dust that falls onto the baffle 21 from the cleaning filter element 9, a worm gear 22 is fixed on the outer side of the support shaft 20 and inside the base frame 10. An L-shaped partition 25 is fixed at the upper end of the base frame 10 and outside the worm gear 22. A second motor 23 is fixed inside the base frame 10 and inside the L-shaped partition 25. A worm 24 is fixed at the output end of the second motor 23, and the worm 24 is meshed with the worm gear 22.

[0036] To ensure that airflow only flows into the ventilation duct 8 through the perforated operating plate 4, the upper ends of the ventilation duct 8, the base frame 10, and the L-shaped partition 25 are all attached to the inner support frame 3.

[0037] Example 2:

[0038] The sanding and dust extraction device for post-processing 3D printing provided in Example 1 has been further optimized, specifically, as follows: Figure 3 As shown, in order to facilitate the control and normal operation of each electrical component in this device, a power supply module 27, a control module 28 and a wireless module 29 are respectively provided at the upper end of the base frame 10 and at one end of the L-shaped partition 25. The control module 28 can be a conventional known device for control, and the existing public power connection technology will not be described in detail here. The mechanical transmission components provided in this utility model are all closed designs that can be opened for maintenance. According to the mechanical manual, as long as they are properly maintained, these mechanical transmission components can normally realize the transmission movement claimed above.

[0039] The process of using the 3D printing post-processing polishing and dust collection device provided by this utility model is as follows: When the 3D printed product is polished on the upper part of the hollow operation plate 4, its dust falls onto the hollow operation plate 4 and continues to fall through the hollow operation plate 4. In order to collect the dust, the dust collection fan 2 is started to draw airflow through the air pipe 6, the air hood 7 and the ventilation tube 8, so that the dust passes through the hollow operation plate 4 and is filtered on the outside of the filter element 9.

[0040] At this time, the first motor 16 is started to drive the second spur gear 17 to rotate. The meshing of the second spur gear 17 and the first spur gear 15 drives the hollow screw barrel 14 to rotate. With the threaded connection between the hollow screw barrel 14 and the reciprocating screw 12, the pusher frame 13 is driven to move back and forth through the guide post 11. This allows the dust brush frame 18 to scrape and clean the outside of the filter element 9. With the vibration motor 19 driving the dust brush frame 18 to vibrate, the cleaning effect is further improved, effectively alleviating the clogging of the filter element 9. This reduces the number of times the staff can manually clean it and the impact on the grinding efficiency. The dust that is cleaned and dropped accumulates on the upper end of the baffle 21.

[0041] When the filter element 9 becomes completely clogged after prolonged vacuuming, requiring manual cleaning by staff, the staff removes the inner support frame 3 to clean the filter element 9. During this process, the second motor 23 is started to drive the worm gear 24 to rotate. The meshing of the worm gear 24 and the worm wheel 22 drives the support shaft 20 to rotate, causing the baffle 21 to flip. This allows the dust accumulated on the baffle 21 to fall into the dust collection box 26 for collection. The dust collection box 26 can then be pulled out for convenient and unified dust cleaning.
