Description

Technical Field

[0001] This invention relates to the field of magnetic head manufacturing technology, and in particular to a dust removal device for magnetic head manufacturing. Background Technology

[0002] When the magnetic head housing is removed from the injection molding machine, some hard lint will remain on its edges, affecting the overall quality. Therefore, it needs to be ground with an angle grinder to remove the hard lint. However, during the grinding process, fine plastic powder will be left on the worktable, which needs to be cleaned. The existing method is to wipe the worktable surface with a cloth and push the fine plastic powder into the trash can. However, because the fine plastic powder is light, it will float up when it is lightly touched by the cloth and then fall back onto the worktable, so it needs to be wiped again, which is inconvenient.

[0003] For example, a dust removal device for magnetic head grinding, disclosed in CN217475577U, while solving the above problems, has the following drawbacks: when a single, fixed-direction dust collection hood is used to collect dust from different areas, it needs to perform the dust collection work sequentially, which leads to low dust collection efficiency and prolonged dust collection time. At the same time, large metal debris falling onto the filter cloth will firstly block some of the pores of the filter cloth and affect the filtration efficiency of the filter cloth. Secondly, the large debris falling onto the filter cloth will slide back and forth on the filter cloth due to the influence of the oscillating filter cloth, causing irreparable damage to the filter cloth during the entire filtration process, thereby affecting its service life. Summary of the Invention

[0004] The purpose of this invention is to provide a dust removal device for magnetic head production.

[0005] The technical problem of this invention is mainly solved by the following technical solution:

[0006] A dust removal device for magnetic head production includes a bottom-sealed cylinder. A protrusion is arranged around the top outer wall of the cylinder. A sliding groove is arranged around both the upper and lower sides of the protrusion. A communication port communicating with the inside of the cylinder is also evenly arranged on the outer wall of the protrusion. A cover is fastened to the protrusion to cover multiple sets of communication ports. An annular slide rail located in the corresponding sliding groove is arranged on the inner wall of the cover. The cover is also connected to a dust collection hood through a corrugated hose.

[0007] A cover plate is movably fixed to the top of the cylinder, and a conical filter screen is fixed to the cover plate by a vertical rod. An electromagnet adsorption plate with a corresponding connection port is provided above the filter screen. A fan is provided inside the cylinder below the filter screen, and an exhaust port is also provided at the bottom of the side wall of the cylinder.

[0008] Preferably, the width of the opening of the cover is adapted to the thickness of the protrusion, and an air circulation channel is formed between the inner wall of the cover and the outer arc wall of the protrusion.

[0009] Preferably, a fixing seat for fixing the corresponding dust collection hood is provided at the bottom of the side wall of the cylinder.

[0010] Preferably, the edge of the filter screen is attached to the inner wall of the cylinder, and a scraper identical to the inner wall of the cylinder is also provided above the filter screen.

[0011] Preferably, a ring of expansion notches is provided around the top corner of the cylinder, a screw tube extending into the expansion notch and screwed to the bottom of the cover plate, a truncated cone-shaped protrusion with an inverted arrangement is provided at the middle of the bottom of the cover plate, the vertical rod is fixedly connected to the middle of the bottom of the protrusion, and the electromagnet adsorption plate is laid on the outer wall of the protrusion.

[0012] Preferably, a filter assembly is movably disposed at the exhaust port to seal it, the filter assembly consisting of an intermediate activated carbon layer and a filter mesh layer surrounding the activated carbon layer.

[0013] Preferably, the sidewall of the slide groove is provided with an electromagnet adsorption layer that contacts the slide rail.

[0014] The beneficial effects of this invention are as follows: By rotating the cover body and driving the slide rail to slide within the slide groove, the orientation of the corrugated hose and dust collection hood changes during the rotation of the cover body. Workers can move multiple sets of dust collection hoods and pull the corrugated hose to contract and expand them, thereby removing dust from different areas on the top of the workbench. When the gas mixed with impurities is drawn into the cylinder, the electromagnet adsorption plate is energized, and the strong magnetic attraction it generates acts on the metal impurities in the air, causing the metal impurities to be adsorbed onto the electromagnet adsorption plate. The airflow then falls after being filtered by the filter screen and is discharged from the exhaust port. When it is necessary to clean the impurities in the cylinder after filtration, the electromagnet adsorption plate is de-energized, causing the metal debris adsorbed on its end face to fall into the filter screen. Then, by rotating the cover plate and driving the spiral tube to rotate upward within the expansion notch, the filter screen is indirectly pulled out of the cylinder. At this time, the conical filter screen can prevent the impurities inside from falling off its edge, thereby facilitating the cleaning of the filtered debris. Attached Figure Description

[0018] The following examples, in conjunction with the appendix, illustrate the concepts. Figure 1-2 The technical solution of the present invention will be further described in detail below.

[0019] A dust removal device for magnetic head production includes a bottom-sealed cylinder 1. A protrusion 2 is arranged around the top outer wall of the cylinder 1. A sliding groove 3 is arranged around both the upper and lower sides of the protrusion 2. A communication port 4 communicating with the inside of the cylinder 1 is also evenly arranged on the outer wall of the protrusion 2. A cover 5 is fastened to the protrusion 2 to cover multiple sets of communication ports 4. An annular slide rail 6 located in the corresponding sliding groove 3 is arranged on the inner wall of the cover 5. An electromagnet adsorption layer in contact with the slide rail 6 is arranged on the side wall of the sliding groove 3. The cover 5 is also connected to a dust collection hood 8 through a corrugated hose 7.

[0020] A cover plate 9 is movably fixed to the top of the inner cylinder 1. A conical filter screen 11 is fixed to the cover plate 9 by a vertical rod 10. An electromagnet adsorption plate 12 corresponding to the communication port 4 is provided above the filter screen 11. A fan 13 is provided inside the cylinder 1 below the filter screen 11. An exhaust port is also provided at the bottom of the side wall of the cylinder 1.

[0021] like Figure 1 , 2 The opening width of the cover 5 is adapted to the thickness of the protrusion 2, and an air circulation channel 14 is formed between the inner wall of the cover 5 and the outer arc wall of the protrusion 2.

[0022] like Figure 1 As shown, a fixing seat 15 for fixing the corresponding dust collection hood 8 is provided at the bottom of the side wall of the cylinder 1.

[0023] like Figure 1 As shown, the edge of the filter screen 11 is attached to the inner wall of the cylinder 1, and a scraper 19 identical to the inner wall of the cylinder 1 is also provided above the filter screen 11.

[0024] The top edge of the inner cylinder 1 is surrounded by an expansion notch. The bottom of the cover plate 9 is provided with a screw tube 16 extending into the expansion notch and screwed thereto. The bottom center of the cover plate 9 is also provided with a truncated cone-shaped protrusion 17 that is inverted. The vertical rod 10 is fixedly connected to the bottom center of the protrusion 17. The electromagnet adsorption plate 12 is laid on the outer wall of the protrusion 17.

[0025] In this embodiment, a filter assembly 18 is movably provided at the exhaust port to seal it. The filter assembly 18 consists of an intermediate activated carbon layer and a filter mesh layer that wraps around the activated carbon layer.

[0026] When in use, the blower 13 operates, creating negative pressure inside the cylinder 1. This negative pressure, through the connecting port 4, air circulation channel 14, corrugated hose 7, and dust collection hood 8, effectively removes debris and dust from the workbench. Workers can move multiple dust collection hoods 8 and pull the corrugated hose 7 to contract and expand, thus removing dust from different areas on the top of the workbench. Simultaneously, rotating the hood 5 causes the slide rail 6 to slide within the slide groove 3, changing the orientation of the corrugated hose 7 and dust collection hood 8 during rotation, making it suitable for dust removal in different directions. When the hood 5 rotates to the designated position, the electromagnet adsorption layer is energized to magnetically fix the slide rail 6, indirectly preventing the hood 5 from rotating on the protrusion 2, thereby positioning the hood 5.

[0027] When gas containing impurities is drawn into cylinder 1, the electromagnet adsorption plate 12 is energized. The strong magnetic force it generates acts on the metal impurities in the air, causing them to adhere to the electromagnet adsorption plate 12. Meanwhile, the airflow passes through filter screen 11, falls, and exits through the exhaust port. The activated carbon layer in the filter assembly 18 then purifies the gas before it is discharged. When cleaning the impurities from cylinder 1 is required after filtration, the electromagnet adsorption plate 12 is de-energized, causing the metal debris adsorbed on its end face to fall into filter screen 11. Then, by rotating the cover plate 9, the screw... The tube 16 is rotated upward within the expansion notch to pull the spiral tube 16 out of the cylinder 1. At the same time, the cover plate 9 drives the scraper 19 to rotate through the protrusion 17, the vertical rod 10 and the filter screen 11. The rotating scraper 19 can scrape off and clean the impurities adhering to the inner wall of the cylinder 1 above the filter screen 11, causing the impurities to fall onto the filter screen 11. After the spiral tube 16 separates from the expansion notch, the filter screen 11 can be pulled out of the cylinder 1 upward. At this time, the conical filter screen 11 can prevent the impurities inside from falling off its edge, thereby facilitating the cleaning of the filtered debris.

[0028] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
