[0039] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Combine the following Figures 1 to 3 , the iron chip cleaning device provided by the embodiment of the utility model is described in detail through specific embodiments and application scenarios.

[0041] In some embodiments, Figure 1 As shown, this embodiment provides an iron chip cleaning device, including: a conveyor belt 1, a bracket 2, an electromagnet 3 and a collecting bucket 4.

[0042] The conveyor belt 1 is used to convey sesame seeds. The bracket 2 is arranged on one side of the conveyor belt 1. The electromagnet 3 is movably arranged on the bracket 2. As the electromagnet 3 moves, the conveyor belt 1 and the collecting bucket 4 are respectively located at the lower side of the electromagnet 3.

[0043] When the conveyor belt 1 is located below the electromagnet 3 , the electromagnet 3 is powered on to absorb iron filings in the sesame seeds; when the collecting bucket 4 is located below the electromagnet 3 , the electromagnet 3 is powered off, and the iron filings absorbed by the electromagnet 3 fall into the collecting bucket 4 .

[0044] It is understandable that after the large foreign matter is removed from the sesame, the fine iron filings need to be removed. The electromagnet 3 can absorb the fine iron filings in the sesame, and the iron filings are absorbed during the process of the conveyor belt 1 conveying the sesame.

[0045] When the electromagnet 3 moves to the top of the conveyor belt 1 , the electromagnet 3 is in a powered state, the electromagnet 3 is magnetic, and the electromagnet 3 has an adsorption force on the iron filings in the conveyor belt 1 , so that the iron filings leave the conveyor belt 1 and are sucked onto the lower surface of the electromagnet 3 .

[0046] When the electromagnet 3 moves to the top of the collecting bucket 4, the electromagnet 3 is in a power-off state, the electromagnet 3 loses its magnetism, and the electromagnet 3 no longer has an adsorption force on the iron filings on its surface. The iron filings slide downward under the action of gravity and slide into the collecting bucket 4 below, thereby realizing the automatic collection of the iron filings on the electromagnet 3.

[0047] Optionally, the electromagnet 3 may move on the bracket 2 along a straight path, may move on the bracket 2 along a folded path, or may move on the bracket 2 along an arc path.

[0048] Specifically, the conveyor belt 1 can be a belt conveyor assembly, and the conveying speed of the conveyor belt 1 can be determined according to the iron filings content in the sesame seeds. When the iron filings content is high, the conveyor belt 1 is conveyed at a lower speed so that the iron filings can be completely adsorbed by the electromagnet 3. When the iron filings content is low, the conveyor belt 1 is conveyed at a higher speed so that more sesame seeds can be conveyed from the conveyor belt per unit time, thereby improving the efficiency of iron filings cleaning.

[0049] In practical applications, one or more electromagnets 3 may be provided. When more than one electromagnet 3 is provided, they may be arranged side by side in the horizontal direction or in the vertical direction on the conveyor belt 1 .

[0050] The iron filings cleaning device provided by the utility model is provided with a collecting bucket 4 and a bracket 2 on one side of a conveyor belt 1, and an electromagnet 3 is movably provided on the bracket 2, so that when the electromagnet 3 is located above the conveyor belt 1, the electromagnet 3 is in a powered-on state, and the iron filings in the sesame on the conveyor belt 1 are adsorbed; when the electromagnet 3 is located above the collecting bucket 4, the electromagnet 3 is in a powered-off state, and the iron filings on the electromagnet 3 fall into the collecting bucket 4, thereby realizing automatic adsorption and collection of the iron filings in the sesame, not only being able to thoroughly clean the iron filings in the sesame, but also improving the efficiency of cleaning the iron filings.

[0051] In some embodiments, Figure 1 and Figure 2 As shown, the iron chip cleaning device of this embodiment further includes: a linear drive 5.

[0052] The linear drive 5 is fixed to the bracket 2 , and an output end of the linear drive 5 is connected to the electromagnet 3 .

[0053] It can be understood that the linear drive 5 drives the electromagnet 3 to approach and move away from the conveyor belt 1 in a straight path to adsorb the iron filings in the sesame on the conveyor belt 1, and send the adsorbed iron filings into the collecting bucket 4. The straight path can ensure that the moving path of the electromagnet 3 is the shortest, thereby improving the moving efficiency of the electromagnet 3, and thereby improving the adsorption and transfer efficiency of the iron filings.

[0054] Specifically, the linear drive 5 can be any one of an electric push rod, a linear motor and a cylinder.

[0055] In some embodiments, Figure 2 As shown, in this embodiment, two electromagnets 3 are provided.

[0056] The two electromagnets 3 are moved alternately to the upper side of the conveyor belt 1 .

[0057] It is understandable that in order to ensure that the electromagnet 3 can continuously absorb the iron filings in the sesame when the conveyor belt 1 continuously conveys sesame, and the iron filings on the electromagnet 3 are removed without affecting the absorption of the iron filings, two electromagnets 3 are arranged in this embodiment. When one electromagnet 3 absorbs iron filings on the conveyor belt 1, the other electromagnet 3 moves to the top of the collecting bucket 4 to make the iron filings fall into the collecting bucket 4. When the electromagnet 3 that absorbs iron filings absorbs more iron filings, the electromagnet 3 moves to the collecting bucket 4. At the same time, the other electromagnet 3 moves to the conveyor belt 1 to absorb iron filings, so that there is always an electromagnet 3 on the conveyor belt 1, and the iron filings on the conveyor belt 1 are always absorbed, which improves the efficiency of iron filing absorption and ensures the reliability of iron filing absorption on the conveyor belt 1.

[0058] Optionally, one collecting bucket 4 can be provided, and the width of the collecting bucket 4 can cover the range of the two electromagnets 3 ; or two collecting buckets 4 can be provided, and the two collecting buckets 4 are provided in one-to-one correspondence with the two electromagnets 3 , respectively.

[0059] Specifically, the present embodiment is provided with two time relays, which are electrically connected to the two linear drives 5 respectively to control the alternating extension and retraction of the two drives, so that the two electromagnets 3 can work together and accurately extend and retract on the conveyor belt 1 alternately, so that there are always electromagnets 3 on the conveyor belt 1 to absorb iron filings. For example, the electromagnet 3 can be set to be powered on for a period of time and powered off for a period of time, and the power-on time period and the power-off time period can be controlled by the time relay.

[0060] In some embodiments, Figure 2 As shown, two collecting barrels 4 are provided in this embodiment.

[0061] It can be understood that the two collecting buckets 4 are respectively located on one side of the conveyor belt 1, and the two collecting buckets 4 are arranged at intervals. The cross-sectional area of ​​the two collecting buckets 4 is slightly larger than the cross-sectional area of ​​the electromagnet 3. When the electromagnet 3 moves to the top of the collecting bucket 4, it can ensure that the iron filings fall into the collecting bucket 4. In this embodiment, two collecting buckets 4 are arranged, which can respectively process the iron filings accumulated in the collecting buckets 4. When the electromagnet 3 above the collecting bucket 4 moves to the conveyor belt 1, the iron filings in the collecting bucket 4 are recovered without affecting the collection of iron filings by the other collecting bucket 4, thereby realizing the dual functions of collection and recovery without interference.

[0062] In some embodiments, Figure 3 As shown, the iron chip cleaning device of this embodiment further includes a light-controlled switch 6 and a controller 7.

[0063] The light-operated switch 6 and the controller 7 are electrically connected.

[0064] The controller 7 controls the working state of the driver and the on and off of the electromagnet 3 according to the iron filings adsorption thickness fed back by the light-controlled switch 6 .

[0065] It is understandable that the iron filings adsorption on the electromagnet 3 has a certain capacity. After the surface of the electromagnet 3 is full of iron filings, the electromagnet 3 can no longer adsorb iron filings. At this time, the surface of the electromagnet 3 needs to be cleaned to avoid affecting the quality of the electromagnet 3 adsorbing iron filings on the conveyor belt 1. The light-controlled switch 6 can monitor the thickness of the iron filings adsorbed on the electromagnet 3 in real time, and feed back the monitored real-time iron filing thickness to the controller 7. The controller 7 compares the real-time iron filing thickness with the preset iron filing thickness. When the real-time iron filing thickness is greater than or equal to the preset iron filing thickness, the controller 7 controls the driver to drive the electromagnet 3 to move to the top of the collection bucket 4, and controls the electromagnet 3 to cut off the power so that the iron filings fall into the collection bucket 4; when the real-time iron filing thickness is less than the preset iron filing thickness, the controller 7 controls the electromagnet 3 to be energized to adsorb the iron filings on the conveyor belt 1.

[0066] This embodiment provides a light-controlled switch 6 and a controller 7 to automatically monitor the adsorption thickness of the electromagnet 3, thereby automatically controlling the adsorption operation of the electromagnet 3 and the operation of removing iron filings, thereby improving the efficiency of adsorbing iron filings and realizing the automation of iron filings cleaning.

[0067] In some embodiments, Figure 3 As shown, the iron chip cleaning device of this embodiment further includes: a first travel switch 8 and a second travel switch 9.

[0068] The first travel switch 8 is arranged on the bracket 2 and is located on the upper side of the conveyor belt 1 . The second travel switch 9 is arranged on the bracket 2 and is located on the upper side of the collecting bucket 4 .

[0069] The first travel switch 8 and the second travel switch 9 are electrically connected to the controller 7 .

[0070] It is understandable that the first travel switch 8 can limit the extended position of the linear drive 5 to the center of the conveyor belt 1, and the second travel switch 9 can limit the retracted position of the linear drive 5 to the center of the collecting bucket 4, so that the linear drive 5 always reciprocates between the center of the conveyor belt 1 and the center of the collecting bucket 4, thereby driving the electromagnet 3 to always reciprocate between the center of the conveyor belt 1 and the center of the collecting bucket 4, so that the electromagnet 3 can switch freely between adsorbing iron filings and storing iron filings, ensuring the accuracy of the power-on position and the power-off position of the electromagnet 3, and improving the accuracy of the adsorption and cleaning of the electromagnet 3.

[0071] This embodiment uses a cylinder to drive the linear movement of the electromagnet 3, and the cylinder has the function of a limit switch. The limit switch can limit the extended position of the cylinder to the center of the conveyor belt 1, and can also limit the retracted position of the cylinder to the center of the collecting bucket 4, so that the cylinder always moves back and forth between the center of the conveyor belt 1 and the center of the collecting bucket 4, ensuring the accuracy of the on and off position of the electromagnet 3, and the structure is compact and easy to debug.

[0072] In some embodiments, Figure 2 As shown, the electromagnet 3 of this embodiment is in a plate shape, and the width of the electromagnet 3 is greater than the width of the conveyor belt 1.

[0073] It is understandable that the electromagnet 3 of this embodiment has a smaller thickness and a larger cross-sectional area, so that the contact area between the electromagnet 3 and the iron filings is larger, which is more conducive to the adsorption of the iron filings on the surface of the electromagnet 3.

[0074] Specifically, the electromagnet 3 may be in the shape of a square plate or a long strip plate.

[0075] By setting the width of the electromagnet 3 to be larger than the width of the conveyor belt 1, this embodiment can ensure that when the electromagnet 3 adsorbs iron filings, the outer edge of the electromagnet 3 can cover both sides of the width of the conveyor belt 1, so that all the iron filings on the conveyor belt 1 located below the electromagnet 3 can be adsorbed, ensuring the adsorption efficiency of the iron filings.

[0076] In some embodiments, Figure 1 and Figure 2 As shown, a slide rail 21 is provided on the bracket 2 of this embodiment.

[0077] The electromagnet 3 is movably disposed on the slide rail 21 along the extending direction of the slide rail 21 .

[0078] It can be understood that the extension direction of the slide rail 21 is extended along the moving direction of the electromagnet 3. When the electromagnet 3 reciprocates above the conveyor belt 1 and the collecting bucket 4, the slide rail 21 provides support and guidance for the movement of the electromagnet 3, so that the linear drive mechanism will not generate torque due to the gravity of the electromagnet 3, thereby affecting the driving function of the linear drive mechanism, ensuring the reliability and stability of the linear drive mechanism. In addition, the moving path of the electromagnet 3 is limited to the slide rail 21, and will not deviate or tilt, which is beneficial to the stability of the extension and retraction of the electromagnet 3.

[0079] In some embodiments, Figure 1 As shown, the opening end 41 of the collecting barrel 4 of this embodiment is in a trumpet shape.

[0080] It can be understood that the open end 41 of the collecting bucket 4 is used to receive the fallen iron filings, and the cross-sectional area of ​​the top of the open end 41 is larger than that of the bottom of the open end 41. The receiving area at the top of the open end 41 is larger, which is more conducive to collecting the iron filings falling from the electromagnet 3. The receiving area from the top to the bottom of the open end 41 gradually decreases, which is more conducive to the iron filings gathering toward the bottom of the bucket during the falling process, thereby achieving the purpose of better collection of iron filings.

[0081] Specifically, the opening end 41 of the present embodiment may be in the shape of a cone or a truncated pyramid.

[0082] In some embodiments, Figure 1 As shown, the collection barrel 4 further includes: a barrel body 43 and a drawer 42 .

[0083] The drawer 42 is installed on the barrel body 43 in a pull-out manner.

[0084] It is understandable that when the iron filings in the collection barrel 4 reach a certain amount, the iron filings in the barrel body 43 need to be cleaned. In this embodiment, a drawer 42 is provided on the barrel body 43, and the iron filings can be cleaned by pulling the drawer 42 out of the barrel body 43 and dumping the iron filings. Compared with turning over the barrel body 43 as a whole and dumping the iron filings from the opening end 41, the drawer 42 of this embodiment can easily clean the iron filings, saving time and effort, and improving the efficiency of iron filings cleaning.

[0085] In some embodiments, Figure 1 As shown, the bracket 2 of this embodiment includes a bracket body 22 and a moving wheel 23 .

[0086] The moving wheel 23 is disposed at the bottom end of the bracket body 22 .

[0087] It is understandable that the moving wheel 23 can drive the movement of the bracket body 22, and the bracket body 22 can move between different conveyor belts 1 to meet the cleaning requirements of different conveyor belts 1 for iron filings.

[0088] Furthermore, the moving wheel 23 of the present embodiment may have a self-locking function. After the bracket body 22 is moved to the target conveyor belt 1, the moving wheel 23 is fixed to one side of the target conveyor belt 1 by self-locking, so that the bracket body 22 is also firmly fixed to one side of the target conveyor belt 1, thereby avoiding the shaking of the bracket body 22 during the iron chip cleaning process to affect the iron chip cleaning effect.

[0089] At the same time, the bracket body 22 of this embodiment includes a first leg, a second leg and a fixed frame, the electromagnet 3 is movably arranged on the fixed frame, the first leg and the second leg are installed below the fixed frame, the first leg is connected to the fixed frame, the second leg and the fixed frame are detachably connected, and the fixed frame can move on the first leg and the second leg in a vertical direction.

[0090] The fixing frame of this embodiment can be adjusted in the vertical direction to adapt to conveyor belts 1 of different heights, and the second leg and the fixing frame are detachably connected, which can ensure that when installing the bracket body 22, the second leg is first removed from the fixing frame, and after it is installed in place, the second leg is installed on the fixing frame. When the space size of the workshop is limited, it is beneficial to the installation of the bracket body 22 and the conveyor belt 1.

[0091] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
