Description

Technical Field

[0001] The utility model relates to the technical field of sorting equipment, in particular to a magnetic particle sorting instrument. Background Art

[0002] The "Glass Beads for Road Marking" (GB / T 24722-2020) specification stipulates that the content of magnetic particles in glass beads should not exceed 0.1%. The presence of magnetic particles may negatively impact the reflective quality and durability of the marking. Excessive magnetic particles in glass beads may attract dust and impurities from the air, causing the surface of the beads to become dirty and reducing their reflective properties. Furthermore, magnetic particles may affect the adhesion between the glass beads and the road marking paint, causing them to fall off or become ineffective. Therefore, during the production and use of glass beads, the magnetic particle content must be strictly controlled to ensure that the product meets regulatory requirements.

[0003] Chinese Patent Publication No. CN205607808U discloses a device for sorting glass beads and magnetic particles, comprising a sorting bracket, a magnet, and a smooth plate. The sorting bracket has an inclined support portion, the magnet is mounted on the inclined support portion of the sorting bracket, and the smooth plate is mounted on the inclined support portion of the sorting bracket to form a smooth inclined surface, with the smooth plate positioned above the magnet. The inclined support portion of the sorting bracket has a feed groove, and / or the smooth plate has a feed groove, with the feed groove positioned above the magnet. It can be seen that after sorting a certain amount of glass beads and magnetic particles, the smooth plate will absorb the sorted magnetic particles and need to be manually removed, otherwise the sorting accuracy of the magnetic particles will be affected.

[0029] The present invention provides a magnetic particle sorting instrument, comprising:

[0030] A bracket 11 is provided with an inclined support portion 12, and the inclined support portion 12 is provided with a plurality of grooves 13 at equal intervals along the inclined direction;

[0031] a plurality of magnets 21 , wherein a single magnet 21 is disposed in the groove 13 ;

[0032] The conveying and sorting part is a conveyor belt structure, wherein the active roller 32 is arranged parallel to one side of the inclined support part 12, and the driven roller 33 is arranged parallel to the other side of the inclined support part 12. The inclined support part 12 is located inside the conveyor belt 31. The active roller 32 is connected to the drive motor 34, and the drive motor 34 is fixed to the bracket 11;

[0033] The collecting portion is provided at the bottom end of the conveying and sorting portion, and includes a first collecting trough 41 for collecting non-magnetic particles and a second collecting trough 42 for collecting magnetic particles.

[0034] Specifically, the spacing between the grooves 13 provided on the inclined support portion 12 is 1-3 cm, which is not specifically limited and can be set according to the diameter of the magnetic particles. In this embodiment, the distance between the grooves 13 is set to 1.2 cm.

[0035] Specifically, the material of the magnet 21 is neodymium iron boron magnet, ferrite magnet or aluminum nickel cobalt magnet, and there is no specific limitation. It only needs to meet the characteristics of the magnet 21 as a permanent magnet. The size and shape of the magnet 21 are also not limited. It only needs to be able to be placed in the groove 13.

[0036] Specifically, the material of the conveyor belt 31 may be polyurethane, which is not specifically limited, so as to reduce the friction of the conveyor belt 31 on the magnetic particles to be sorted.

[0037] Specifically, the ratio of the length of the groove 13 to the width of the inclined support portion 12 is less than 2 / 3. With this arrangement, the surface of the conveyor belt 31 for sorting magnetic particles can be divided into a sorting area and a drop area. A groove 13 for placing the magnet 21 is provided below the sorting area, so that the sorting area has a magnetic field and the drop area has no magnetic field. As the conveyor belt 31 is transported from the sorting area to the drop area, non-magnetic particles are sorted in the sorting area and fall into the first collection trough 41. The surface of the conveyor belt 31 in the sorting area adsorbs the magnetic particles and transports them to the drop area. In the drop area, the magnetic particles fall into the second collection trough 42 due to gravity, thus achieving automatic sorting of the magnetic particles.

[0038] Specifically, the angle between the inclined support portion 12 and the horizontal plane is 40-60°. It can be understood that the angle between the inclined support portion 12 and the horizontal plane is 40-60°, which can ensure the sorting rate and accuracy. When the angle is less than 40°, the sorting rate decreases. When the angle is greater than 60°, the sorting rate increases, but the sorting accuracy decreases.

[0039] Specifically, a support plate 51 is provided between the conveyor belt 31 and the inclined support portion 12. The material of the support plate 51 is, for example, plastic. The setting of the support plate 51 can isolate the magnet 21 from direct contact with the conveyor belt 31, thereby preventing the conveyor belt 31 from causing the magnet 21 to move relative to the conveyor belt 31.

[0040] Specifically, the device further comprises a feeding section, which is located at the top of the conveying and sorting section and includes a silo 61 for storing magnetic particles to be sorted and a feeding port 62 for discharging the particles. It is understood that the silo 61 can store a large amount of magnetic particles to be sorted, avoiding multiple manual spreading operations and improving the automation level and efficiency of the sorting process.

[0041] Specifically, the cross-sectional shape of the feeding port 62 is rectangular, and the cross-sectional length of the feeding port 62 is consistent with the cross-sectional length of the silo 61. Such a configuration can increase the discharge area and further improve the sorting efficiency.

[0042] Specifically, the width of the cross section of the feed port 62 is greater than the diameter of the magnetic particles to be sorted and less than 1 / 3 of the height of the silo 61. There is no specific limitation. Such a setting can make the magnetic particles to be sorted be smoothly output from the feed port 62, and prevent the output of a large number of magnetic particles to be sorted from causing the magnetic particles to accumulate on the surface of the conveyor belt 31 and affecting the sorting of non-magnetic particles.

[0043] Specifically, a scraper 71 is provided on the top surface of the conveyor belt 31, near the driven roller 33. The vertical distance between the scraper 71 and the conveyor belt 31 is set to be less than the diameter of the magnetic particles to be separated. This arrangement allows all magnetic particles in the drop zone of the conveyor belt 31 to be removed and transferred to the second collection trough 42 without affecting the normal transport of the conveyor belt 31.
