[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this utility model belongs. The terms used in the description of this utility model herein are only for the purpose of describing specific implementation manners and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0046] In one embodiment of the present utility model, a portable magnetic rack device is provided. Please refer to Figure 1 . The magnetic rack device includes: a magnetic rod assembly 1, a magnetic rod sleeve assembly 2, and a collection box 3.

[0047] The collection box 3 can be located below the magnetic rod sleeve assembly 2. Pull the insertion plate 301 of the collection box 3 out completely in the horizontal direction, and the open structure 302 around the box wall will pop up upward under the action of the internal force of the support springs 3031 - 3040. Then, pull out the magnetic rod assembly 1 in the vertical direction, and the iron objects adsorbed on the magnetic rod sleeve assembly 2 will fall downward accordingly, and completely fall into the collection box 3 along the chip falling gap on the magnetic rod sleeve bottom plate 203 and the space between the side plates 302. Finally, just collect the iron objects in the collection box 3 through the iron object outlet 304.

[0048] Optionally, please refer to Figure 2 . The magnetic rod assembly 1 includes a magnetic rod top plate 101 and magnetic rods 102. The magnetic rod top plate 101 and the magnetic rods 102 are firmly fixed by welding to avoid the problem that the magnetic rods 102 loosen during the cleaning of the magnetic rack and affect the cleaning process.

[0049] The magnetic rod top plate 101 is a rectangular plate, and the magnetic rods 102 on it are all distributed in a form of column separation and staggering. The distance between two adjacent magnetic rods 102 in each column of magnetic rods is 6 - 7 cm, and the distance between two adjacent columns of magnetic rods is 4 - 5 cm. Such an arrangement and distribution can, on the one hand, avoid the problem of adhesion of the magnetic rods 102 caused by small spacing between the magnetic rods 102 and large magnetic field intensity, and on the other hand, can also ensure that the combination of magnetic rods 102 obtains a higher magnetic field intensity and feeding efficiency, thus ensuring the stability of production. The contour of the magnetic rods 102 is set to be cylindrical, and the bottom of the magnetic rods 102 is set to be hemispherical, which makes it smooth when the magnetic rods 102 are inserted into the magnetic rod sleeve 202.

[0050] Please refer to Figure 3, the magnetic bar sleeve assembly 2 includes a magnetic bar sleeve top plate 201, a magnetic bar sleeve 202, and a magnetic bar sleeve bottom plate 203. The magnetic bar sleeve bottom plate 203 is also provided with a chip falling gap. The chip falling gap is in an I-shaped. Two columns of magnetic bar sleeves 202 are located on both sides of the chip falling gap. The magnetic bar sleeve assembly 2 plays a role in protecting and fixing the magnetic bar 102 and adsorbing iron. Multiple magnetic bar sleeves 202 can be sleeved outside multiple magnetic bars 102 one by one. The depth of the magnetic bar sleeve 202 is 1 - 2 cm more than the length of the magnetic bar 102. When the magnetic bar 102 is sleeved in the magnetic bar sleeve 202, the lower end of the magnetic bar 102 is located inside the magnetic bar sleeve 202 and does not extend out of the magnetic bar sleeve 202. The diameter of the insertion hole on the magnetic bar sleeve top plate 201 and the magnetic bar sleeve 202 is 1 - 2 cm larger than the diameter of the magnetic bar 102. The distance between the insertion hole on the magnetic bar sleeve top plate 201 and the magnetic bar sleeve 202 matches the distribution of the magnetic bars 102. The distance between two adjacent magnetic bar sleeves 202 in each column of magnetic bar sleeves is 5 - 7 cm, and the distance between two adjacent columns of magnetic bar sleeves in the vertical direction is 3 - 5 cm, ensuring that the magnetic bars 102 can be completely inserted into the magnetic bar sleeves 202 and ensuring the smooth entry and exit of the magnetic bars 102.

[0051] The magnetic bar sleeve bottom plate 203 seals the lower end of the magnetic bar sleeve 202 to prevent iron chips from entering its interior. Among them, the connection point between the magnetic bar sleeve bottom plate 203 and the lower end of the magnetic bar sleeve 202 is at least 1.5 - 2 cm away from the edge of the magnetic bar sleeve bottom plate 203, so as to ensure the strength of the magnetic bar sleeve bottom plate 203. The area of the chip falling gap on the magnetic bar sleeve bottom plate 203 accounts for 50 - 60% of the bottom plate area, so as to ensure that iron can smoothly fall into the collection box 3.

[0052] Please refer to Figure 4 , in this embodiment, the collection box 3 includes a plug board 301 and an open structure 2. The open structure can be operably telescoped upward, and when it retracts into the collection box 3, it is blocked and covered by the plug board 301. The open structure has two front and rear vertical side plates 3021, 3022 and two left and right inclined plates 3023, 3024 arranged oppositely; the two front and rear vertical side plates 3021, 3022 and the two left and right inclined plates enclose the open structure. An elastic component for pushing the open structure to move upward is provided inside the collection box 3. The elastic component includes six support springs 3031 - 3036 for supporting the vertical side plates and four support springs 3037 - 3040 for supporting the inclined plates.

[0053] Specifically, the collection box 3 includes two vertical side plates 3021-3022, two inclined plates 3023-3024 at a certain angle to the vertical direction, six support springs 3031-3036 for the vertical side plates, four support springs 3037-3040 for the inclined plates, and an iron outlet 304. The insertion plate 301 in the collection box 3 can be stretched flexibly in the horizontal direction without affecting the fall of iron into the collection box 3.

[0054] Please refer to Figure 5 , both of the two vertical side plates 3021-3022 and the two inclined plates 3023-3024 in the collection box can extend 5-6 cm in the vertical direction under the action of the internal force of the support springs 303. The two inclined plates 3023-3024 form an angle of 60-70° with the vertical direction to ensure that the iron does not fall outside the collection box 3. The open structure 2 moves upward, leaving enough space at the bottom of the collection box to accommodate iron debris (metal impurities), and suspending the magnetic rod sleeve assembly through the support magnetic rod sleeve bottom plate 203 to facilitate the fall of the iron debris and avoid the difficulty of discharging the iron when the magnetic rod sleeve bottom plate 203 touches the bottom. In addition, the protruding open structure can also facilitate the discharge of the entering iron from the iron outlet 304.

[0055] Please refer to Figure 6 , the collection box 3 includes ten support springs 3031-3040. Among them, the two ends of six support springs 3031-3036 respectively abut against the two vertical side plates 3021-3022 and the bottom of the collection box 3, and the two ends of four support springs 3037-3040 respectively abut against the two inclined plates 3023-3024 and the bottom of the collection box 3. The movement of the side plates 302 extending outward comes from the internal force generated by the support springs 303.

[0056] Optionally, please refer to Figure 7 , the circular iron outlet 304 in the collection box 3 is tangent to the bottom of the collection box 3, and the diameter of the circular iron outlet 304 is set to 5-6 cm, so that the collected iron can be easily collected from the collection box 3.

[0057] Any numerical values recited herein include all values from the lower value to the upper value incremented by one unit therebetween, provided that there is a separation of at least two units between any lower value and any higher value. For example, if the value of the number of components or a process variable (such as temperature, pressure, time, etc.) is recited as being from 1 to 90, preferably from 20 to 80, more preferably from 30 to 70, it is intended thereby to disclose also expressly values such as 15 to 85, 22 to 68, 43 to 51, 30 to 32, etc. For values less than 1, a unit is appropriately considered to be 0.0001, 0.001, 0.01, 0.1. These are merely examples of what is intended to be expressed, and all possible combinations of numerical values recited between the lowest value and the highest value are to be considered to be expressly stated in this specification in a similar manner.

[0058] Unless otherwise stated, all ranges include the endpoints and all numbers therebetween. The term “about” or “approximate” used in connection with a range is to be construed as being suitable for both endpoints of the range. Thus, “about 20 to 30” is intended to cover “about 20 to about 30”, including at least the recited endpoints.
