Description

Technical Field

[0001] This utility model provides a dust removal device with protective components, belonging to the field of dust removal technology in machining. Background Technology

[0002] Dust removal devices are widely used in the field of machining technology. Their core function is to use negative pressure airflow to adsorb dust and particulate matter, thereby purifying or recycling dust generated during machining. A typical dust removal device usually includes a vacuum cleaner, a suction pipe, and a filtration system. Among these, the suction pipe, as the component that directly contacts the pollutants, has a structural design that directly affects dust removal efficiency and equipment reliability.

[0003] In existing technologies, a filter or protective grid is typically installed at the end of the suction pipe to protect the dust collection device and prevent large particles (such as debris, metal flakes, etc.) from being sucked into the suction pipe, causing blockage or damage to the fan. However, the presence of the filter also brings new problems: the higher the mesh density of the filter, the better the effect of blocking large particles, but at the same time, it increases airflow resistance, leading to a decrease in suction power. When adsorbing fine dust, a dust layer easily forms on the filter surface, further hindering airflow. Depending on different working conditions, it is often necessary to choose whether or not to use a filter, and when using a filter, it is often necessary to select a filter with an appropriate mesh density to balance the filtration effect and the impact on suction power. However, existing filters are usually fixed with screws or snap-fit ​​connections, requiring tools (such as screwdrivers and wrenches) for replacement, which is cumbersome and time-consuming. In scenarios where frequent switching of working conditions is required, it is impossible to quickly adjust the filter configuration, affecting work efficiency. Therefore, there is an urgent need for a suction end protection component that can be quickly disassembled or selected to solve the above problems. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing dust removal devices are inconvenient to quickly disassemble or replace filters with different mesh densities according to changes in actual working conditions, thereby achieving rapid configuration and increasing the protection effect on the dust removal device.

[0005] To solve the above problems, the proposed technical solution is as follows: a dust removal device with protective components, including a vacuum cleaner; the vacuum cleaner is installed on the side of a processing table, an L-shaped bracket is fixedly installed on the processing table, and processing equipment is installed inside the bracket; it also includes:

[0006] The machine includes a suction pipe and a rotating plate. A sliding plate is slidably mounted on the processing table. A suction pipe for vacuuming the working area of ​​the processing table is fixedly mounted on the sliding plate and is connected to the working end of a vacuum cleaner. The rotating plate is rotatably mounted inside a bracket. The rotating plate has several evenly distributed circumferential connecting holes. Only one connecting hole does not have a filter screen, while the other connecting holes have filters with different mesh densities. The suction pipe is located on the rotation path of all the connecting holes and is connected to one of the connecting holes.

[0007] As an improvement, the connection hole is provided with four holes, three of which are provided with filters of different mesh densities, and the last connection hole is a through hole without a filter.

[0008] As an improvement, the end of the suction pipe is fixedly connected to a tube that communicates with the suction pipe. The outer diameter of the tube corresponds to the inner diameter of the connection hole, and the tube is inserted into one of the connection holes.

[0009] As an improvement, a support plate is fixedly connected inside the bracket by a connecting rod, and a rotating motor is installed on the support plate, with the output end of the rotating motor fixedly connected to the rotating plate.

[0010] As an improvement, a sliding groove is provided in the processing table, and an electric telescopic rod is installed in the sliding groove; the working end of the electric telescopic rod is fixedly connected to a slider that is slidably disposed in the sliding groove, and a guide groove communicating with the sliding groove is provided on the processing table, and the slider passes through the guide groove and is fixedly connected to the sliding plate.

[0011] As an improvement, the working end of the vacuum cleaner is connected to a connecting hose, and the connecting hose is connected to a rigid suction pipe on the sliding plate.

[0012] The beneficial effects of this utility model are:

[0013] The rotating plate is rotatably mounted inside the bracket. The rotating plate has several evenly distributed circumferential connection holes. Only one connection hole is not fitted with a filter screen, while the other connection holes are fitted with filter screens of different mesh densities. By setting up the rotating plate, the filter screen can be quickly replaced, or the filter screen can be left unused. After replacement, the sliding plate drives the suction pipe to connect with the connection hole, which can quickly and conveniently complete the filter screen replacement, greatly improving the filter screen replacement efficiency.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] This utility model provides a dust removal device with protective components: including a vacuum cleaner 8; the vacuum cleaner 8 is disposed on the side of the processing table 1, and an L-shaped bracket 2 is fixedly disposed on the processing table 1, and a processing device 3 is disposed inside the bracket 2. The processing device 3 is prior art, and its specific structure will not be described further.

[0021] like Figure 1 As shown, a sliding plate 7 is slidably arranged on the processing table 1. A vacuum pipe 6, which can vacuum the working area of ​​the processing table 1, is fixedly arranged on the sliding plate 7, and the vacuum pipe 6 is connected to the working end of the vacuum cleaner 8. The working end of the vacuum cleaner 8 is connected to a sufficiently long connecting hose, and the connecting hose is connected to the rigid vacuum pipe 6 on the sliding plate 7. The setting of the connecting hose can ensure that the vacuum cleaner 8 can still be connected to the vacuum pipe 6 when the sliding plate 7 drives the vacuum pipe 6 to slide.

[0022] like Figure 3 As shown, a slide groove 14 is provided in the processing table 1, and an electric telescopic rod 13 is provided in the slide groove 14; a slider 16 that is slidably disposed in the slide groove 14 is fixedly connected to the working end of the electric telescopic rod 13; a guide groove 15 that communicates with the slide groove 14 is provided on the processing table 1, and the slider 16 passes through the guide groove 15 and is fixedly connected to the sliding plate 7; by providing the electric telescopic rod 13, the sliding control of the sliding plate 7 can be conveniently achieved.

[0023] like Figure 1 , 2 As shown, the rotating plate 4 is rotatably mounted inside the bracket 2. The rotating plate 4 has several evenly distributed circumferential connecting holes 5. Only one connecting hole 5 is not equipped with a filter screen 9, while the other connecting holes 5 are equipped with filter screens 9 of different mesh densities. A support plate 11 is fixedly connected inside the bracket 2 via a connecting rod 10. A rotating motor 12 is mounted on the support plate 11, and the output end of the rotating motor 12 is fixedly connected to the rotating plate 4. The rotating motor 12 facilitates the rotation control of the rotating plate 4.

[0024] There are four connection holes 5. Three of the connection holes 5 contain filters 9 with different mesh densities, and the last connection hole 5 is a through hole without a filter 9. The suction pipe 6 connects to one of the connection holes 5, and the suction pipe 6 is located on the rotation path of all the connection holes 5, which ensures that any connection hole 5 can connect to the suction pipe 6 when the rotating plate 4 is rotated.

[0025] like Figure 4 As shown, a tube 17 is fixedly connected to the end of the vacuum tube 6 and communicates with the vacuum tube 6. The outer diameter of the tube 17 corresponds to the inner diameter of the connection hole 5, and the tube 17 is inserted into one of the connection holes 5.

[0026] The principle of this utility model

[0027] like Figure 1 , 2 As shown, when processing equipment 3 is used to process the parts on processing table 1, the dust removal device is in normal working order. The insert 17 at the end of the suction pipe 6 is inserted into the connection hole 5. The vacuum cleaner 8 is started, and the dust generated in the processing area is vacuumed through the connecting hose, suction pipe 6, connection hole 5, and filter screen 9. The filter screen 9 can prevent some large impurities from splashing into the suction pipe 6. When the working conditions change, it is often necessary to replace the filter screen 9 with one of different mesh densities or to disassemble the filter screen 9. The specific operation is as follows:

[0028] like Figure 3 , 4 As shown, first, start the electric telescopic rod 13, using the slider 16 to move the sliding plate 7 and the suction pipe 6 away from the processing equipment 3 until the insert 17 disengages from the connecting hole 5; then start the rotary motor 12 to rotate the rotating plate 4, so that the connecting hole 5 corresponding to the filter screen 9 with different mesh densities aligns with the insert 17, or the connecting hole 5 without the filter screen 9 aligns with the insert 17 (the specific choice depends on the actual working conditions); then start the electric telescopic rod 13 again, using the sliding of the sliding plate 7 to insert the insert 17 into the connecting hole 5, completing the connection between the suction pipe 6 and the filter screen 9 in the connecting hole 5. The removal or replacement of the filter screen 9 is quick and convenient, without involving the removal and installation of screws or other fasteners.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
