Abstract
Description
Technical Field
[0001] This utility model relates to the field of screening device technology, specifically to a screening device for screw processing. Background Technology
[0002] The choice of screw material directly determines its mechanical properties, environmental resistance, and applicable scenarios. It is necessary to comprehensively weigh the load type, environmental conditions, cost, and machinability. Iron screws are mainly made of carbon steel, and high strength and basic corrosion resistance are achieved through heat treatment and surface treatment. They are suitable for general fastening needs in neutral environments. During the processing of iron screws, debris will adhere to their surface, so a screening device is needed to separate the debris and screws.
[0003] When screening devices separate iron screws and debris, the iron screws are added to the screen and slide down. The debris on the iron screws falls through the mesh of the screen, thus completing the separation of iron screws and debris. The debris at the screening point includes iron filings and dust impurities. Current screening devices do not have a structure to separate the iron filings and dust impurities from the sieved debris, which makes it inconvenient to recycle the iron filings. This problem should be addressed and improved.
[0004] Therefore, a screening device for screw processing is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a screening device for screw processing in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] A screening device for screw processing includes a housing and a door, with the door and housing slidably installed. The housing contains a screening component for collecting iron filings from the debris, and the screening component is equipped with an electromagnet. A first slot and a second slot are respectively opened on both sides of the housing, with the second slot adapted to the screening component. A screen for filtering debris from the surface of iron screws is slidably installed on one inner wall of the housing, and the screen is inclined. A support plate is fixedly installed on the other inner wall of the housing to support the other side of the screen. A dust removal component for sucking up dust from inside the screening component is located on one outer wall of the housing and inside the first slot.
[0008] Furthermore, the screening component includes a box body, the box body has an interior, and the left and right sides of the box body are open. An iron plate is slidably provided on the bottom inner side of the box body, and a cavity is opened on one side of the iron plate. The electromagnet is fixedly installed inside the cavity, and a handle is fixedly provided on one side of the iron plate.
[0009] Furthermore, the iron plate is L-shaped and is adapted to the second slot.
[0010] Furthermore, the openings on the left and right sides of the iron plate correspond to the first slot and the second slot, respectively, and the bottom inner side of the iron plate is flush with the bottom inner side of the first slot.
[0011] Furthermore, the dust removal assembly includes a dust removal box, which is fixedly installed on one outer wall of the box body. A fan is fixedly installed on the surface of the dust removal box, an air pipe is fixedly installed on the fan, and an air collection hood is fixedly installed at the other end of the air pipe.
[0012] Furthermore, the gas collecting hood is adapted to the first slot, and the surface of the gas collecting hood is in contact with the inner wall of the first slot.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. This utility model adds an appropriate amount of iron screws to the surface of the screen. The iron screws slide off the surface of the screen, and the debris on the surface of the iron screws passes through the mesh of the screen and falls into the interior of the screening component. When the electromagnet on the screening component is energized, the iron filings in the debris are attracted. At this time, the dust removal component attracts the debris inside the screening component, and the iron filings are attracted to the screening component. Other dust and impurities pass through the first slot into the interior of the dust removal component. The iron filings inside the screening component can be cleaned and collected through the second slot. Under the action of the screening component and the dust removal component, the iron filings and dust impurities can be separated, which facilitates the screening of iron filings and their subsequent recycling. The screen and the box can be disassembled by sliding. After the screen and the box are slidably installed, the sliding door closes it. After the door is closed, it can limit the screen in the horizontal direction, thereby realizing the limiting installation of the screen. Attached Figure Description

[0023] like Figures 1 to 3As shown, a screening device for screw processing includes a housing 1 and a door 2, with the door 2 slidably installed on the housing 1. The housing 1 contains a screening component 3 for collecting iron filings from debris, and the screening component 3 is equipped with an electromagnet. A first slot 4 and a second slot 5 are respectively opened on both sides of the housing 1, and the second slot 5 is adapted to the screening component 3. A screen 6 for filtering iron screw debris is slidably installed on one inner wall of the housing 1, and the screen 6 is inclined. A support plate 7 is fixedly installed on the other inner wall of the housing 1 to support the other side of the screen 6. A dust removal component 8 for sucking up dust from inside the screening component 3 is provided on one outer wall of the housing 1 and inside the first slot 4. Specifically, an appropriate amount of iron screws is added to the surface of the screen 6, and the iron screws are... As the iron screw slides down, the debris on its surface passes through the mesh of the screen 6 and falls into the interior of the screening component 3. When the electromagnet on the screening component 3 is energized, it attracts the iron filings from the debris. At this time, the dust removal component 8 attracts the debris inside the screening component 3, and the iron filings are attracted onto the screening component 3. Other dust and impurities pass through the first slot 4 and enter the interior of the dust removal component 8. The iron filings inside the screening component 3 can be cleaned and collected through the second slot 5. Under the action of the screening component 3 and the dust removal component 8, the iron filings and dust impurities can be separated, which facilitates the screening of iron filings and their subsequent recycling. The screen 6 and the box 1 can be detached by sliding. After the screen 6 and the box 1 are slidably installed, the sliding door 2 closes it. After the door 2 is closed, it can limit the screen 6 in the horizontal direction, thereby realizing the limited installation of the screen 6.
[0024] like Figure 2 , Figure 3 As shown, the screening component 3 includes a box 301. The box 301 is located inside the housing 1, and both the left and right sides of the box 301 are open. An iron plate 302 is slidably provided on the bottom inner side of the box 301. A cavity 303 is opened on one side of the iron plate 302. An electromagnet is fixedly installed inside the cavity 303. A handle 304 is fixedly provided on one side of the iron plate 302. Specifically, when the debris falls onto the surface of the iron plate 302, when the electromagnet is energized, the iron filings in the debris are attracted to the iron plate 302. By pulling the handle 304, the iron plate 302 is moved through the second slot 5 to the outside of the housing 1. At this time, the electromagnet is de-energized, and the iron filings can be cleaned and collected.
[0025] like Figure 2 , Figure 3As shown, the iron plate 302 is L-shaped and is adapted to the second slot 5; specifically, when the iron plate 302 is located inside the box 1, one side of the iron plate 302 can fit against the inner wall of the second slot 5, thereby sealing the second slot 5.
[0026] like Figure 2 , Figure 3 As shown, the openings on the left and right sides of the iron plate 302 correspond to the first slot 4 and the second slot 5, respectively, and the bottom inner side of the iron plate 302 is flush with the bottom inner side of the first slot 4. Specifically, the dust removal component 8 can adsorb dust and impurities on the surface of the iron plate 302 through the first slot 4, and iron filings are adsorbed on the iron plate 302. The dust and impurities are absorbed by the dust removal component 8 through the first slot 4.
[0027] like Figure 1 , Figure 2 As shown, the dust removal assembly 8 includes a dust removal box 801. The dust removal box 801 is fixedly installed on one outer wall of the box body 1. A fan 802 is fixedly installed on the surface of the dust removal box 801. An air pipe 803 is fixedly installed on the fan 802. An air collection hood 804 is fixedly installed at the other end of the air pipe 803. Specifically, when the fan 802 is started, it adsorbs the air inside the box body 1. Dust and impurities on the surface of the iron plate 302 enter the air pipe 803 through the first slot 4 with the air and are introduced into the dust removal box 801 through the air pipe 803.
[0028] like Figure 1 , Figure 2 As shown, the gas collecting hood 804 is adapted to the first slot 4, and the surface of the gas collecting hood 804 is in contact with the inner wall of the first slot 4; specifically, the gas collecting hood 804 can seal the first slot 4, and under the action of the gas collecting hood 804, the area of the air inlet can be expanded, and dust and impurities enter the air pipe 803 through the gas collecting hood 804.
[0029] In summary: When an appropriate amount of iron screws is added to the surface of the screen 6, the iron screws slide off the surface of the screen 6, and the debris on the surface of the iron screws passes through the mesh of the screen 6 and falls into the interior of the screening component 3. When the electromagnet on the screening component 3 is energized, the iron filings in the debris are attracted. At this time, the dust removal component 8 attracts the debris inside the screening component 3, and the iron filings are attracted to the screening component 3. Other dust and impurities pass through the first slot 4 and enter the interior of the dust removal component 8. The iron filings inside the screening component 3 can be cleaned and collected through the second slot 5. Under the action of the screening component 3 and the dust removal component 8, the iron filings and dust impurities can be separated, which facilitates the screening of iron filings and facilitates the subsequent recycling of iron filings. The screen 6 and the box 1 can be disassembled by sliding. After the screen 6 and the box 1 are slidably installed, the sliding door 2 closes it. After the door 2 is closed, it can limit the screen 6 in the horizontal direction, thereby realizing the limited installation of the screen 6.
