Description
Technical Field
[0001] This application relates to the field of dust treatment technology, and more specifically, to dust treatment apparatus. Background Technology
[0002] A 3D printer, also known as a three-dimensional printer, is a machine that uses rapid prototyping technology. It is a technology that uses a digital model file as a basis and employs powdered metal or plastic and other adhesive materials to construct objects by printing layer by layer. It is a cumulative manufacturing technology that creates three-dimensional objects by printing layers of adhesive materials.
[0003] Existing technology publication CN219903389U discloses a dust removal device for a 3D printer, including a 3D printer body; a dust removal mechanism connected to the 3D printer body, the dust removal mechanism including a mounting base connected to the 3D printer body and a dust collection component, a dust collection box fixedly connected to the top of the mounting base, and a vacuum cleaner mounted on one side of the dust collection box; the dust collection component including a mounting block connected to the 3D printer body, a suction pipe connected to one side of the mounting block via a fixing plate, a positioning plate connected to the other side of the mounting block, one end of the suction pipe communicating with the dust collection box via a flexible hose, and the other end communicating with a dust collection hood. This invention, by installing the dust collection component on a guide rod assembly in the 3D printer body, allows it to rise and fall synchronously with the print head in the 3D printer body, thereby timely absorbing the dust generated during printing, thus preventing dust from flowing into the working environment with the air and minimizing the risk of harm to the health of workers.
[0004] Although the device has many beneficial effects, it still has the following problems: during the printing process, some dust will fall on the top of the printing table, and during the dust removal process, it is difficult to clean the tightly attached dust on the printing table, which can easily reduce the dust treatment effect. In view of this, we propose a dust treatment device. Utility Model Content
[0005] This application provides a dust treatment device that solves the technical problem in the prior art where some dust falls on the top of the printing table during printing, and it is difficult to clean the tightly attached dust on the printing table during dust removal, thus easily reducing the dust treatment effect. The device facilitates repeated vibration of the support plate, which shakes up the tightly attached dust on the support plate and the housing, and then uses an exhaust fan to extract the shaken dust, thereby improving the dust treatment effect inside the housing.
[0006] This application provides a dust handling device, including: a housing;
[0007] The printing device body is installed inside the housing. A mounting groove is opened through the bottom of the housing, and a support plate is rotatably connected in the mounting groove. A through groove is opened through one side of the housing, and a filter screen is fixedly connected in the through groove. A slot is opened through the other side of the housing, and an exhaust fan is installed in the slot. A dust exhaust pipe is fixedly connected to the other side of the housing.
[0008] The bottom of the housing is provided with a vibration mechanism for striking the support plate;
[0009] The oscillation mechanism includes a fixed plate with a through hole at the bottom. A slide rod is slidably connected inside the hole. A limit plate is fixedly connected to the bottom end of the slide rod, and a connecting frame is fixedly connected to the top end of the slide rod. A spring is fixedly connected to the bottom of the connecting frame, and the bottom end of the spring is fixedly connected to the top of the inner wall of the fixed plate.
[0010] By adopting the above technical solution, after the printing is completed and the printed object is removed from the support plate, the support plate can be tapped and vibrated, thereby shaking up the tightly attached dust on the top of the support plate and the bottom of the inner wall of the shell. Then, the dust can be extracted by the exhaust fan, which facilitates the improvement of the dust treatment effect inside the shell.
[0011] Optionally, a bracket is fixedly connected to the bottom of the housing, a motor is mounted on the top of the bracket, and the top of the output shaft of the motor is fixedly connected to the bottom of the support plate.
[0012] By adopting the above technical solution, when the motor starts, it can drive the support plate to rotate. Thus, after the staff removes the printed object from the support plate, the staff does not need to reach deep into the inner side of the shell to scrape off the clumps generated on the support plate for cleaning.
[0013] Optionally, a connecting groove is provided through both sides of the connecting frame, and a rotating shaft is rotatably connected in the connecting groove by a ball bearing, and a roller is fixedly sleeved on the outside of the rotating shaft.
[0014] By adopting the above technical solution, when the support plate rotates, the rollers in contact with the support plate can be rotated by the support plate, thereby preventing the connecting frame from directly contacting the support plate and causing serious wear to the support plate, thus facilitating the extension of the service life of the support plate.
[0015] Optionally, a sealed bearing is installed in the mounting groove, and the support plate is rotatably connected to the mounting groove through the sealed bearing.
[0016] By adopting the above technical solution and setting a sealed bearing, the gap between the support plate and the inner wall of the mounting groove can be sealed, thereby preventing dust from falling onto the bracket through the gap between the support plate and the inner wall of the mounting groove during the printing process.
[0017] Optionally, a washer is fixedly sleeved on the outside of the roller, and the washer is made of rubber.
[0018] By adopting the above technical solution, the gasket material is relatively soft, which can play a certain buffering role when the gasket comes into contact with the support plate, thus preventing the generation of more serious noise.
[0019] Optionally, a connecting block for cooperating with the roller is fixedly connected to the bottom of the support plate, and the height of the connecting block gradually increases from one side to the other.
[0020] By adopting the above technical solution, when the connecting block rotates with the support plate, once the connecting block contacts the roller, the roller, the rotating shaft and the connecting frame can gradually move downward. The connecting frame compresses the spring. When the connecting block separates from the roller, the compressed spring rebounds, which enables the connecting frame, the rotating shaft and the roller to rise rapidly and move to strike the support plate, thereby improving the dust handling efficiency.
[0021] Optionally, a baffle is hinged to the front of the housing, and a limiting groove is formed through one side of the baffle, with an observation window fixedly connected in the limiting groove.
[0022] By adopting the above technical solution, and by setting up a baffle and an observation window, when printing, the staff can close the baffle and use the observation window to observe the printing process inside the casing.
[0023] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0024] 1. By setting up a vibration mechanism, the support plate can be repeatedly vibrated, which makes the tightly attached dust on the support plate and the shell shake up. Then, the dust shaken up is extracted by the exhaust fan, thereby improving the treatment effect of dust inside the shell.
[0025] 2. By setting a sealed bearing, the gap between the support plate and the inner wall of the mounting groove can be sealed, thereby preventing dust from falling onto the bracket through the gap between the support plate and the inner wall of the mounting groove during the printing process.
[0026] 3. By setting up a motor, support plate, connecting block and spring, when the connecting block, which rotates with the support plate, contacts the roller, the roller, the shaft and the connecting frame gradually move downwards, causing the connecting frame to compress the spring. When the connecting block separates from the roller, the compressed spring rebounds, causing the roller to rise rapidly and move to strike the support plate, thereby improving the dust handling efficiency.

Detailed Implementation
[0032] The present application will be further described in detail below with reference to the accompanying drawings.
[0033] Reference Figure 1 and Figure 2 This application discloses a dust treatment device. The dust treatment device includes: a housing 1;
[0034] The printing device body is installed inside the housing 1. A mounting groove is opened through the bottom of the housing 1, and a support plate 6 is rotatably connected in the mounting groove. A through groove is opened through one side of the housing 1, and a filter screen 5 is fixedly connected in the through groove. A slot is opened through the other side of the housing 1, and an exhaust fan 2 is installed in the slot. A dust exhaust pipe 4 is fixedly connected to the other side of the housing 1.
[0035] The bottom of the housing 1 is provided with a vibration mechanism 3 for striking the support plate 6;
[0036] The vibration mechanism 3 includes a fixed plate 33 with an opening through the bottom of the fixed plate 33. A slide rod 34 is slidably connected in the opening. A connecting frame 35 is fixedly connected to the top of the slide rod 34. A spring 39 is fixedly connected to the bottom of the connecting frame 35. The bottom end of the spring 39 is fixedly connected to the top of the inner wall of the fixed plate 33, so as to facilitate the tapping and vibration of the support plate 6, thereby treating the relatively dense dust adhering to the support plate 6.
[0037] Reference Figure 2 and Figure 3A bracket 8 is fixedly connected to the bottom of the housing 1, and a motor 31 is installed on the top of the bracket 8. The top of the output shaft of the motor 31 is fixedly connected to the bottom of the support plate 6, so as to facilitate the rotation of the support plate 6. After printing, the staff can remove the clumps adhering to the support plate 6 without having to reach deep into the inside of the housing 1.
[0038] Reference Figure 2 and Figure 4 The bottom end of the slide rod 34 is fixedly connected to a limiting plate 310. The size of the limiting plate 310 is larger than the size of the inner side of the opening, so as to prevent the slide rod 34 from falling out of the opening.
[0039] Reference Figure 2 and Figure 4 The connecting frame 35 has connecting grooves on both sides, and a rotating shaft 36 is rotatably connected in the connecting grooves through ball bearings. A roller 37 is fixedly sleeved on the outside of the rotating shaft 36, so that the roller 37 can contact the support plate 6. When the support plate 6 rotates, the roller 37 can be rotated, reducing the wear on the connecting frame 35 and the support plate 6 and extending the service life of the support plate 6.
[0040] Reference Figure 1 and Figure 2 A sealed bearing 7 is installed in the mounting groove. The support plate 6 is rotatably connected to the mounting groove through the sealed bearing 7, which facilitates the sealing treatment of the gap between the support plate 6 and the mounting groove, and prevents dust from falling directly onto the bracket 8 through the gap between the mounting groove and the support plate 6.
[0041] Reference Figure 2 and Figure 4 A washer 38 is fixedly fitted on the outer side of the roller 37. The washer 38 is made of rubber and is relatively soft. This reduces damage to the roller 37 and effectively reduces noise when the support plate 6 is struck.
[0042] Reference Figure 2 and Figure 3 The bottom of the support plate 6 is fixedly connected to a connecting block 32 for cooperating with the roller 37. The height of the connecting block 32 gradually increases from one side to the other, so that the staff no longer need to manually pull the limiting plate 310 downward.
[0043] Reference Figure 1 and Figure 2 The front of the housing 1 is hinged to a baffle 9. A limiting groove is opened through one side of the baffle 9, and an observation window 10 is fixedly connected in the limiting groove to facilitate the staff to observe the printing process inside the housing 1.
[0044] The implementation principle of the dust treatment device in this application embodiment is as follows: when dust is generated during the printing process, the exhaust fan 2 can be activated to introduce external air into the inside of the housing 1 through the filter screen 5, and then into the dust discharge pipe 4 through the exhaust fan 2, and finally the dust generated inside the housing 1 is discharged into the external filter through the dust discharge pipe 4.
[0045] After printing is complete, the printed object is removed from the support plate 6. If there is some dust adhered tightly to the support plate 6, the motor 31 can be started. The motor 31 will rotate the support plate 6 within the mounting slot. The rotation of the support plate 6 will cause the connecting block 32 to rotate. As the connecting block 32 rotates, the roller 37 will move from the highest point of the bottom of the connecting block 32 to the lowest point. At this time, the roller 37 will move downwards, thereby causing the rotating shaft 36 and the connecting frame 35 to move downwards. The downward movement of the connecting frame 35 will drive... The slide bar 34 moves vertically within the opening, and the connecting frame 35 compresses the spring 39. When the roller 37 is completely separated from the connecting block 32, the compressed spring 39 rebounds, thereby driving the connecting frame 35, the rotating shaft 36, and the roller 37 to move upward. The movement of the roller 37 can drive the washer 38 to move, thereby using the washer 38 to strike the support plate 6, which causes the dust attached to the support plate 6 and the bottom of the inner wall of the housing 1 to be shaken up. Finally, the exhaust fan 2 is used to extract the shaken dust and discharge it into the external filter.
[0046] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer. Those skilled in the art can connect all electrical components in this case to their compatible power supplies via wires. Appropriate controllers should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described above, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art, therefore, electrical control will not be described further.
