[0035] Further, the inside of the main body 10 is formed with a cavity corresponding to the outer contour thereof, the cavity penetrates through both ends of the main body 10 along the axis direction of the main body 10, so as to form a feeding port 101 and a discharging port at the first end (i.e. the first end of the first cylindrical section away from the variable-diameter section) and the second end (i.e. the second end of the second cylindrical section away from the variable-diameter section) of the main body 10 respectively, the positive material enters the cavity from the feeding port 101 and is discharged from the discharging port, and the main body 10 arranged in the above structure can increase the smoothness of the discharge of the positive material, for example, the inclined inner wall of the variable-diameter section facilitates the falling of the positive material, and the discharging port with small caliber facilitates the concentration of the positive material. It should be noted that the specification of the main body 10 is not specifically limited, as long as it can facilitate the implementation of the above technical effects.

[0036] Further, the outside wall of the first cylindrical section is further provided with two connecting blocks 102, the connecting blocks 102 are used for connecting the magnetic field removing device with the bracket of the packaging equipment and are also used for connecting the magnetic field removing part.

In order to facilitate the description of each component, the radial direction formed by the connecting line of the two connecting blocks 102 is formed as a first direction, which is perpendicular to the axis direction of the main body 10.

[0037] In addition, the two connecting blocks 102 are further provided with slide rails 103, the extension direction of the slide rails 103 is the second direction, which is perpendicular to the first direction and the axial direction of the main body 10. It should be noted that the specifications of the connecting blocks 102 are not specifically limited, which should be determined according to the actual situation, as long as the above technical effects can be achieved. In addition, since the specifications of the connecting blocks 102 in the embodiment are small, the slide rails 103 penetrate through the corresponding connecting blocks 102 along the second direction, so as to facilitate the pulling of the following magnetic removal assembly. The slide rails 103 and the following slide bars 114 are assembled and correspondingly slide connected, which belongs to the prior art (for example, the structure of the slide rails 103 of the drawer), and therefore the structure principle of the slide rails 103 and the following slide bars 114 will not be described in detail.

[0038] In the embodiment, the magnetic removal part includes a plurality of magnetic removal assemblies arranged at the feed port 101, each of which is correspondingly slide connected with the slide rails 103 through the slide bars 114, so that each of the magnetic removal assemblies can slide relative to the main body 10. Specifically, each of the magnetic removal assemblies includes a plurality of magnetic rods 111 spaced apart along the first direction; each of the magnetic rods 111 extends along the second direction, which is perpendicular to the first direction and perpendicular to the axial direction of the main body 10. More specifically, each of the magnetic removal assemblies further includes a connecting rod 113 and a slide bar 114 corresponding to the slide rail 103; the connecting rod 113 extends along the first direction, and the two slide bars 114 are connected (by screws) to the two ends of the extension direction of the connecting rod 113; correspondingly, the slide bar 114 extends along the second direction, and the connecting rod 113 is located at the first end of the extension direction of the slide bar 114.

In this way, when the slide bar 114 slides relative to the slide rail 103, the corresponding magnetic rod 111 can be driven to slide synchronously by the connecting rod 113, thereby facilitating the cleaning of the magnetic rod 111. Correspondingly, the side wall of the first cylindrical section is provided with a hollow part 104 for facilitating the pulling of the magnetic removal assembly, and the specific structure and size of the hollow part 104 are not limited.

Such arrangement can facilitate the falling of the positive electrode material, that is, the inclined side wall of the stainless steel layer 112 can play a guiding role. The thickness of the stainless steel layer 112 should not affect the demagnetization effect of the magnetic rod 111.

[0042] According to the demagnetization device of the utility model, the demagnetization device is arranged between the lower package buffer bin and the star feeder, the magnetic material adhered to the positive electrode material during the discharging process of the positive electrode material can be eliminated by the demagnetization part of the demagnetization device, so as to ensure the quality of the finally output positive electrode material. Further, the demagnetization assembly in the demagnetization part is slidably connected with the main body 10, that is, each demagnetization assembly can be individually extracted, which is convenient for cleaning and use.

[0043] According to the second aspect of the utility model, a positive electrode material packaging equipment is provided, wherein the positive electrode material packaging equipment comprises the demagnetization device as described above; in addition, the positive electrode material packaging equipment further comprises an electromagnetic iron remover, a lower package buffer bin, a star feeder and a packaging machine, and the electromagnetic iron remover, the lower package buffer bin, the demagnetization device, the star feeder and the packaging machine are sequentially arranged.
