It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein.

[0069] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0070] As mentioned in the background technology, in the prior art, magnetic rod cleaning is to manually wash the magnetic rod with a high-pressure water pipe, and the impurities adsorbed on the magnetic rod are removed by the high-pressure water. This operation mode will significantly reduce the magnetism of the magnetic rod after multiple high-pressure water washings, resulting in unsatisfactory adsorption effect of the magnetic rod in subsequent use.

[0071] In order to solve the above-mentioned technical problems, one or more embodiments of the present application provide a magnetic rod cleaning device, which removes impurities on the magnetic rod through a mechanical structure, throws the removed impurities outward with the help of rotating centrifugal force, and carries away the impurities through low-pressure or pressureless water flow, thereby achieving the beneficial effect of automatically removing impurities on the surface of the magnetic rod without affecting the magnetic properties of the magnetic rod.

[0072] The magnetic rod cleaning device is described in detail below with reference to the accompanying drawings.

[0073] like Figure 1 and Figure 2 As shown, the magnetic rod cleaning device provided in the embodiment of the present application includes:

[0074] A rotating shaft 8 is used to insert the magnetic rod to be cleaned;

[0075] Rotating blades 13 are arranged on the rotating shaft 8 along the circumferential direction, and each rotating blade 13 encloses a channel through which the magnetic bar can pass but will touch the outer surface of the magnetic bar when rotating;

[0076] The power mechanism is connected to the rotating shaft 8 and is used to drive the rotating shaft 8 and the rotating blades 13 thereon to rotate so as to remove impurities on the surface of the magnetic rod;

[0077] The cleaning mechanism includes a first chamber 18 arranged on the outer periphery of the rotating blade 13, and the first chamber 18 is connected to the water inlet pipe 14 and the water outlet pipe 16; the cleaning mechanism is configured as follows: the cleaning liquid is injected from the water inlet pipe 14, mixed with the discarded impurities in the first chamber 18, and the mixed liquid is discharged through the water outlet pipe 16.

[0078] Further, a magnetic bar inlet 18-1 is provided at the channel inlet corresponding to the rotating blade 13 on the first chamber 18. The size of the magnetic bar inlet 18-1 is larger than the size of the magnetic bar. Usually, the magnetic bar is cylindrical, so the magnetic bar inlet 18-1 is a circle with a diameter larger than the diameter of the magnetic bar.

[0079] Combination Figure 3 and Figure 4 The rotating shaft 8 is a hollow cylindrical structure with an inner diameter larger than the magnetic rod. The inner wall of the inlet end of the rotating shaft 8 is provided with a plurality of first grooves 8-1 along the circumferential direction. The end of each rotating blade 13 is connected and fixed to the rotating shaft 8 through the first groove 8-1, and the main body of the rotating blade 13 is located at the front side of the inlet end of the rotating shaft 8. A cylindrical channel with a diameter slightly larger than the diameter of the magnetic rod is enclosed in the middle of each rotating blade 13. Specifically, the size of the channel satisfies: the magnetic rod can pass through, and the rotating blade 13 will touch the outer surface of the magnetic rod when rotating to remove impurities on the magnetic rod, but will not damage the outer surface of the magnetic rod.

[0080] In the above embodiment, under the centrifugal force of the rotating blade 13, the impurities to be thrown outward are thrown outward, so the first chamber 18 is provided to collect the impurities to be thrown out and to serve as a chamber for mixing the cleaning liquid and the impurities. The first chamber 18 is provided at the outer periphery of the rotating blade 13 and is connected and fixed to the rotating shaft 8. In a preferred embodiment, the water inlet pipe 14 is provided above the first chamber 18, and the water outlet pipe 16 is provided below the first chamber 18.

[0081] When the magnetic rod cleaning device provided in the above embodiment is working, the power mechanism drives the rotating shaft 8 and the rotating blades 13 thereon to rotate, and the magnetic rod is inserted into the magnetic rod inlet 18-1 and continues to move forward under the drive of the external driving force. When passing through the rotating blades 13, the impurities on the surface of the magnetic rod are discarded by the rotating blades 13, and the clean magnetic rod continues to move forward through the rotating shaft 8 and is discharged; under the centrifugal force of the rotating blades 13, the discarded impurities are thrown outward into the first chamber 18; the cleaning liquid is injected from the water inlet pipe 14, mixed with the impurities in the first chamber 18, and the mixed liquid is discharged through the water outlet pipe 16.

[0082] In the above embodiment, impurities on the surface of the magnetic bar are mainly removed by the rotating blades 13, and the main function of the cleaning liquid is to carry away and discharge the impurities removed by the rotating blades 13. Therefore, the cleaning liquid does not need to be set to high pressure, but can be set to low pressure, or even without external pressure, relying only on the gravity of the cleaning liquid itself. In this way, impurities on the surface of the magnetic bar can be removed by automated equipment without affecting the magnetism of the magnetic bar.

[0083] The low pressure is relative to the pressure of high-pressure water in the prior art, and the low pressure is a pressure that does not affect the magnetic properties of the magnetic rod.

[0084] Furthermore, in the above embodiment, the magnetic rod cleaning device also includes an aperture mechanism 12, which is arranged on the rotating shaft 8 and located on the rear side (exit side) of the rotating blade 13, and is used to finely scrape the surface of the magnetic rod after rough polishing by the rotating blade 13 to ensure the cleanliness of the magnetic rod surface.

[0085] Combination Figure 5 and Figure 6 The aperture mechanism 12 includes a chassis 12-1, a movable plate 12-2, an aperture scraper 12-3, a fixed plate 12-4, a spring 12-5, an automatic lever 12-6, etc.

[0086] Specifically, the chassis 12-1 is disc-shaped, including a circular bottom and a peripheral wall vertically connected to the circular bottom. A first circular hole 12-1-1 is provided in the center of the circular bottom for the magnetic rod to pass through. The diameter of the first circular hole 12-1-1 is larger than the magnetic rod. An arc-shaped pull groove 12-1-2 is provided on one side of the peripheral wall.

[0087] The spring 12-5 is arranged inside the peripheral wall, and one end of the spring 12-5 is connected to one end of the pull groove 12-1-2. Schematically, one end of the spring 12-5 is fixed to the inner side of the peripheral wall at one end of the corresponding pull groove 12-1-2 by a first bolt 12-7. The other end of the spring 12-5 is fixed to a second bolt 12-8, and the second bolt 12-8 is arranged in the pull groove 12-1-2 and can slide along the pull groove 12-1-2. In the natural state of the spring 12-5, the second bolt 12-8 is located in the pull groove 12-1-2 near one end of the first bolt 12-7.

[0088] Combination Figure 7The movable plate 12-2 includes a circular body 12-2-1 and an L-shaped connecting plate 12-2-2. The circular body 12-2-1 is arranged in the chassis 12-1. The L-shaped connecting plate 12-2-2 passes through the shifting groove 12-1-2 from the outside of the chassis 12-1 and is connected and fixed to the circular body 12-2-1. The L-shaped connecting plate 12-2-2 is provided with a bolt hole 12-2-3. The automatic shifting lever 12-6 passes through the bolt hole 12-2-3 on the L-shaped connecting plate 12-2-2 and is connected to the second bolt 12-8 in the shifting groove 12-1-2. The automatic shifting lever 12-6 is fixedly connected to the L-shaped connecting plate 12-2-2 through the bolt hole 12-2-3.

[0089] When external force is applied, such as hand-held or other power mechanisms, the automatic lever 12-6 is driven to rotate, and the automatic lever 12-6 will drive the movable plate 12-2 to rotate along the groove 12-1-2. When it rotates to the other end of the groove 12-1-2, the spring 12-5 is in a stretched state. At this time, if the automatic lever 12-6 is released, the movable plate 12-2 will rotate back to the initial position under the action of the restoring force of the spring 12-5.

[0090] Furthermore, a second circular hole 12-2-4 is provided at the center of the circular body 12-2-1 for the magnetic rod to pass through. The diameter of the second circular hole 12-2-4 is greater than the diameter of the magnetic rod, and preferably, greater than or equal to the diameter of the first circular hole 12-1-1. A polygonal first movable groove 12-2-5 is provided on the outer periphery of the second circular hole 12-2-4 for mounting the aperture scraper 12-3, and the first movable groove 12-2-5 does not penetrate the movable plate 12-2. The number of sides of the polygon is consistent with the number of the aperture scraper 12-3.

[0091] Combination Figure 8 The main body of the fixed plate 12-4 is circular, and its diameter is consistent with that of the circular main body 12-2-1 of the movable plate 12-2. A third circular hole 12-4-4 is provided in the center of the fixed plate 12-4 for the magnetic rod to pass through. The diameter of the third circular hole 12-4-4 is larger than the diameter of the magnetic rod, and preferably, is consistent with the diameter of the first circular hole 12-1-1. A second movable groove 12-4-2 is provided on the fixed plate 12-4, and the number of the second movable grooves 12-4-2 is consistent with the number of the aperture scrapers 12-3. In an optional embodiment, there are 6 aperture scrapers 12-3, the first movable groove 12-2-5 is a regular hexagon, and the second movable groove 12-4-2 is six straight grooves arranged in a clockwise direction along the circumferential direction.

[0092] Combination Fig. 9The main body of the aperture scraper 12-3 is triangular, and a first limiting protrusion 12-3-1 is provided on one side of the aperture scraper 12-3 for matching with the first movable groove 12-2-1 on the movable plate 12-2; a second limiting protrusion 12-3-2 is provided on the other side of the aperture scraper 12-3 for matching with the second movable groove 12-4-2 on the fixed plate 12-4.

[0093] The aperture scraper 12-3 is installed between the movable plate 12-2 and the fixed plate 12-4, the first limiting protrusion 12-3-1 of the aperture scraper 12-3 is inserted into the first moving groove 12-2-1, and the second limiting protrusion 12-3-2 is inserted into the second moving groove 12-4-2.

[0094] Furthermore, combined with Figure 8 The fixing plate 12-4 is also provided with a screw hole 12-4-1, and the corresponding position of the upper edge of the peripheral wall of the chassis 12-1 is also provided with a screw hole. The fixing plate 12-4 is connected and fixed to the chassis 12-1 by screws, so that the movable plate 12-2 and the aperture scraper 12-3 are encapsulated between the chassis 12-1 and the fixing plate 12-4. Furthermore, one side of the fixing plate 12-4 extends outward to form an extension plate 12-4-3. The extension plate 12-4-3 and the upper edge of the L-shaped connecting plate 12-2-2 are matched and fixed.

[0095] Combination Figure 3 The rotating shaft 8 is provided with a first opening slot 8-4, and the packaging structure formed by connecting the chassis 12-1 and the fixing plate 12-4 is installed inside the rotating shaft 8 and is located at the rear side (exit side) of the rotating blade 13. The automatic lever 12-6 is located outside the rotating shaft 8, and the automatic lever 12-6 passes through the first opening slot 8-4 and is connected to the packaging structure.

[0096] Furthermore, a second groove 8-3 is provided on the inner wall of the rotating shaft 8 for positioning and cooperating with the extension plate 12-4-3 of the packaging structure.

[0097] Furthermore, a baffle 8-2 is provided on the inner wall of the rotating shaft 8, and the baffle 8-2 is provided on the rear side of the aperture mechanism 12 to limit the axial displacement of the aperture mechanism 12 in the rotating shaft 8. In some embodiments, the baffle 8-2 is a circle of protrusions extending radially inward along the inner wall of the rotating shaft 8; in the axial direction, the baffle 8-2 is provided on the rear side (the side close to the outlet) of the first opening groove 8-4.

[0098] In the natural state, the aperture scrapers 12-3 are fitted together and cover the second circular hole 12-2-4 on the movable plate 12-2, so that the passage between the first circular hole 12-1-1 on the chassis 12-1 and the third circular hole 12-4-4 on the fixed plate 12-4 is closed. At this time, the aperture mechanism 12 is in the closed state, and the automatic lever 12-6 is located at one end in the first opening groove 8-4.

[0099] During operation, the automatic lever 12-6 moves to the other end in the first opening groove 8-4, and the automatic lever 12-6 rotates along the lever groove 12-1-2 with the movable plate 12-2. The aperture scrapers 12-3 are relatively displaced, and the aperture mechanism 12 gradually opens.

[0114] In the above embodiment, the method of using the magnetic rod cleaning device is as follows:

[0115] Put the magnetic rod to be cleaned into the magnetic rod inlet 1-4, use the automatic lever 12-6 to open the aperture mechanism 12, and let the magnetic rod pass through the aperture mechanism 12; then remove the automatic lever 12-6, and under the restoring force of the spring 12-5, the aperture mechanism 12 is closed, the aperture scraper and the magnetic rod are tightly fitted, and the magnetic rod is clamped by the aperture mechanism 12;

[0116] Turn on the motor 6, and drive the transmission shaft 3 and the rotating shaft 8 to rotate through gear transmission. The rotating shaft 8 drives the brush 11, the aperture mechanism 12 and the rotating blade 13 thereon to rotate, and the transmission shaft 3 drives the screw rod 15 to rotate;

[0117] The magnetic bar moves forward at a constant speed under the action of the external driving force, first passing through the rotating blades 13, and the impurities on the surface of the magnetic bar are roughly polished by the rotating blades 13; then passing through the aperture mechanism 12, the remaining impurities on the surface of the magnetic bar are finely scraped by the aperture scraper 12-3; then passing through the brush 11, the remaining impurities on the surface of the magnetic bar are finely swept by the brush 11, and finally discharged through the magnetic bar outlet 1-1. At the same time, the impurities are thrown outward by the centrifugal force of the rotating blades 13, and the cleaning liquid is injected from the water inlet pipe 14, mixed with the impurities that are roughly polished in the first chamber 18, and then enter the second chamber 19, and are rotated and transported to the water outlet pipe 16 by the screw rod 15 to complete the chip removal.

[0118] Optionally, a magnetic rod is clamped by a robotic arm and inserted into the magnetic rod inlet 1-4, and a motor is used to drive the magnetic rod to move forward at a constant speed into the magnetic rod cleaning device provided in the embodiment of the present application, thereby achieving gradual cleaning of a long magnetic rod from one end to the other.

[0119] In another optional embodiment, the magnetic bar may be fixed, and the magnetic bar cleaning device may be driven to move forward along the magnetic bar to achieve cleaning of the magnetic bar.

[0120] The magnetic rod cleaning device provided in the embodiment of the present application removes impurities on the magnetic rod through a mechanical structure, throws the removed impurities outward with the help of the rotating centrifugal force, and carries the impurities away through a low-pressure or pressureless water flow, thereby achieving the beneficial effect of removing impurities on the surface of the magnetic rod without affecting the magnetic properties of the magnetic rod.

[0121] The present application uses an automated device to clean the magnetic rod, which greatly improves the efficiency of magnetic rod cleaning compared to traditional manual cleaning methods.

[0122] Furthermore, the magnetic rod cleaning device provided in the embodiment of the present application cleans the magnetic rod through three processes of rough polishing, fine scraping and fine sweeping, thereby ensuring the cleanliness of the surface of the magnetic rod.

[0123] Among them, rotating blades are used for rough throwing. While throwing away impurities, the impurities can be thrown outward with the help of rotating centrifugal force, which is convenient for separating impurities and magnetic bars.

[0124] The aperture mechanism is used for fine scraping to ensure the scraping pressure while being compatible with the outer diameter error of the magnetic rod. The outer wall of the magnetic rod may be damaged during use. Since the aperture mechanism has an adjustable opening and closing degree, the aperture scraper will fit tightly with the magnetic rod at the damaged outer wall, ensuring that impurities at the damaged outer wall of the magnetic rod will also be scraped off.

[0125] On the other hand, the inner diameter of the aperture mechanism can be adjusted according to the outer diameter of the magnetic rod. Therefore, the magnetic rod cleaning device provided in the embodiment of the present application is adaptable to magnetic rods of various sizes and specifications and has strong versatility.

[0126] Furthermore, since the aperture mechanism has an adjustable opening and closing degree, even if the aperture scraper is worn under a high workload, the magnetic rod can be clamped again by adjusting the opening and closing degree of the aperture mechanism. The device has a long service life and stable and reliable performance.

[0127] At the same time, the magnetic rod cleaning device provided in the embodiment of the present application uses a spiral rod to automatically collect removed impurities such as iron filings, which is convenient and efficient to handle.
