Description

Technical Field

[0001] The utility model belongs to the technical field of color sorters, in particular to a dust-cleaning magnetic brush for color sorters. Background Art

[0002] The existing color sorter is equipped with glass in the structural design of the sorting box. The main function of the glass is to block, seal, and form a transparent area in the box area, so that the light source inside the box can penetrate and illuminate the material and the camera can capture the surface information of the material through the glass, so that the camera can capture the complete and clear material through the glass. However, in actual operation, the color sorter is often affected by the characteristics of some materials to be sorted. For example, the material itself is easy to leak liquid or contain small particles of impurities. When the belt bed is running, liquid and impurities are easy to fall on the glass of the sorting box under the belt bed, making the outside of the glass blurred, causing the light source, background, and camera to be unable to effectively capture the characteristics of the material, thereby reducing the machine's sorting clarity. In order to keep the machine stable in sorting clarity, the outside of the glass needs to be cleaned.

[0003] The patent application entitled “A Strong Magnetic Cleaning Brush Tool” (Announcement No.: CN 217963690 U) discloses a scheme in which inner and outer magnetic brushes are attracted to each other between the glass, and the inner magnetic brush is driven by a single inner rodless cylinder to reciprocate on the glass to remove impurities formed on the glass surface during operation. In the above scheme, the outer magnetic brush is placed directly on the glass without a retaining frame during the movement, and is completely maintained in a moving state by the magnetic attraction of the inner magnetic brush. However, when there are too many impurities on the outer surface of the glass, the outer magnetic brush will encounter too much resistance during operation, resulting in a phenomenon of inner and outer asynchronism; the outer magnetic brush is prone to shaking and detaching, and cannot effectively clean glass stains. Utility Model Content

[0004] The utility model provides a dust-cleaning magnetic brush for a color sorter, which aims to realize synchronous and smooth movement of inner and outer magnetic brushes and effectively remove stains on the outer surface of glass.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A color sorter dust cleaning magnetic brush, wherein corresponding positions on the inner and outer sides of the light-transmitting glass of the sorting machine box are provided with inner magnetic brushes and outer magnetic brushes that attract and stick to each other, the inner magnetic brush slides along the length direction of the surface where the light-transmitting glass is located when driven by an inner driving mechanism, and the outer magnetic brush slides along the length direction of the surface where the light-transmitting glass is located when driven by an outer driving mechanism, and the inner magnetic brush and the outer magnetic brush move synchronously.

[0007] In the above scheme, the corresponding positions on the inner and outer sides of the light-transmitting glass of the sorting machine box are respectively provided with inner magnetic brushes and outer magnetic brushes that attract and stick to each other. The inner magnetic brush and the outer magnetic brush are driven by the inner driving mechanism and the outer driving mechanism to slide synchronously along the length direction of the surface where the light-transmitting glass is located, so as to avoid the problem that when there are too many impurities on the outer surface of the light-transmitting glass, the outer magnetic brush is subject to large resistance, and the inner and outer magnetic brushes cannot move synchronously and smoothly, resulting in the inner and outer magnetic brushes cannot attract each other. The inner and outer magnetic brushes can move synchronously and smoothly, and are stably attracted, so that stains on the outer surface of the glass can be effectively removed.

[0018] like Figure 1 A color sorter dust cleaning magnetic brush is shown, and an inner magnetic brush 10 and an outer magnetic brush 20 that attract and stick to each other are disposed at corresponding positions on the inner and outer sides of the light-transmitting glass A1 of the sorting machine case A. The inner magnetic brush 10 slides along the length direction of the surface where the light-transmitting glass A1 is located when driven by the inner driving mechanism 30, and the outer magnetic brush 20 slides along the length direction of the surface where the light-transmitting glass A1 is located when driven by the outer driving mechanism 40. The inner magnetic brush 10 and the outer magnetic brush 20 move synchronously.

[0019] In the above scheme, the inner and outer magnetic brushes 10 and 20 that attract and stick to each other are arranged at corresponding positions on the inner and outer sides of the light-transmitting glass A1 of the sorting box A. While the inner and outer magnetic brushes 10 and 20 attract each other under the action of magnetic force, the inner driving mechanism 30 and the outer driving mechanism 40 drive the inner and outer magnetic brushes 10 and 20 to slide synchronously along the length direction of the surface where the light-transmitting glass A1 is located, ensuring that even when there is a lot of dirt on the outer side of the light-transmitting glass A1 of the sorting box A that hinders the displacement of the outer magnetic brush 20, the sliding of the inner and outer magnetic brushes 10 and 20 along the length direction of the surface where the light-transmitting glass A1 is located can still be kept synchronized, and the strong magnets between the inner and outer magnetic brushes 10 and 20 are always facing each other, ensuring that the inner and outer magnetic brushes 10 and 20 can always be stably attracted to each other, avoiding the shaking or even falling of the outer magnetic brush 20, and ensuring that the outer magnetic brush 20 can effectively remove stains on the outer surface of the glass.

[0020] like Figures 2-3 As shown, the inner driving mechanism 30 includes an inner cylinder tube 31 fixed inside the sorting box A and with the rod length direction consistent with the length direction of the light-transmitting glass A1, and an inner slider 32 sleeved on the inner cylinder tube 31. The two ends of the inner cylinder tube 31 are connected with relatively arranged inner mounting plates 33, and the upper part of the inner mounting plate 33 is fixedly connected to the inner plate surface of the top plate A2 of the sorting box A.

[0021] The outer driving mechanism 40 includes an outer cylinder tube 41 fixed to the outside of the sorting box A and the length direction of the rod is consistent with the length direction of the light-transmitting glass A1, and an outer slider 42 sleeved on the outer cylinder tube 41. The two ends of the outer cylinder tube 41 are connected to relatively arranged outer mounting plates 43, and the lower part of the outer mounting plate 43 is fixedly connected to the outer plate surface of the rear plate A3 of the sorting box A.

[0022] In the above scheme, the inner driving mechanism 30 and the outer driving mechanism 40 are supplied with air to the inner cylinder tube 31 and the outer cylinder tube 41 by a rodless cylinder at the same time, ensuring that the thrusts received by the inner slider 32 and the outer slider 42 are the same, thereby realizing the synchronous displacement of the inner slider 32 and the outer slider 42. Furthermore, an intake throttle valve can be added at the air supply points of the inner cylinder tube 31 and the outer cylinder tube 41 to balance the thrusts of the inner cylinder tube 31 and the outer cylinder tube 41.

[0023] like Figure 3 As shown, the inner driving mechanism 30 and the inner magnetic brush 10 are connected via an inner bracket 50. The inner bracket 50 includes an inner connecting plate 51 and an inner fixing frame 52 which are arranged at an angle. The inner connecting plate 51 is fixedly connected to the lower part of the inner slider 32, and the inner magnetic brush 10 is installed on the inner fixing frame 52.

[0024] In the above scheme, the inner driving mechanism 30 and the inner magnetic brush 10 are connected through the inner bracket 50, the inner connecting plate 51 is fixedly connected to the lower part of the inner slider 32, and the inner magnetic brush 10 is installed on the inner fixed frame 52, so that the inner magnetic brush 10 can slide along the length direction of the surface where the light-transmitting glass A1 is located.

[0025] like Figure 2 As shown, the outer driving mechanism 40 is connected to the outer magnetic brush 20 via an outer bracket 60, and the outer bracket 60 includes an outer connecting plate 61 and an outer fixing frame 62. The outer connecting plate 61 has the same combined contour as the top plate A2 and the rear plate A3 of the sorting machine box A. The outer connecting plate 61 is fixedly connected to the upper part of the outer slider 42, and the outer magnetic brush 20 is installed on the outer fixing frame 62. An upper cleaning frame 80 pointing to the front end material distribution chamber is fixed on the outer connecting plate 61.

[0026] In the above scheme, the outer driving mechanism 40 is located outside the sorting box A. In order to realize the close arrangement of the outer driving mechanism 40 and the sorting box A and avoid occupying too much external space, the outer driving mechanism 40 is located on the rear plate A3 of the sorting box A. The outer driving mechanism 40 and the outer magnetic brush 20 are connected by an external bracket 60. The outer bracket 60 has the same combined contour as the top plate A2 and the rear plate A3 of the sorting box A, so that the outer driving mechanism 40 drives the outer magnetic brush 20 from the rear plate A3 of the sorting box A. Furthermore, an upper cleaning frame 80 pointing to the front end material separation chamber is fixed on the external connecting plate 61, so that the upper cleaning frame 80 cleans the front end material separation chamber while the outer driving mechanism 40 drives the outer magnetic brush 20.

[0027] Further, such as Figure 1 , 3 As shown, an overhanging plate 53 is connected to the inner slider 32, and the rear plate A3 of the sorting box A is located on the rotation path of the overhanging plate 53 around the inner cylinder tube 31 away from the light-transmitting glass A1, and the overhanging end of the overhanging plate 53 is close to the inner plate surface of the rear plate A3 of the sorting box A.

[0028] In the above scheme, the outer magnetic brush 20 needs to be removed and replaced after being used for a period of time. When the outer magnetic brush 20 is removed, the inner magnetic brush 10 will not be affected by the magnetic attraction force from the outer magnetic brush 20. Under the action of gravity, the inner magnetic brush 10 will naturally rotate around the inner cylinder tube 31 away from the light-transmitting glass A1. Therefore, the present application sets an overhang plate 53 on the inner slider 32, whose overhang end is close to the inner plate surface of the rear plate A3 of the sorting box A. When the outer magnetic brush 20 is removed, the present scheme allows the inner magnetic brush 10 to rotate at a small angle within the range of magnetic adsorption. When the overhang end of the overhang plate 53 abuts against the inner plate surface of the rear plate A3 of the sorting box A, although the inner magnetic brush 10 cannot rotate further, it is still within the range of magnetic adsorption. Therefore, when the new outer magnetic brush 20 is installed, under the action of magnetic force, the inner magnetic brush 10 will naturally re-match with the outer magnetic brush 20, and there is no need to manually support the inner magnetic brush 10.

[0029] Further, such as Figure 1 , 2 As shown, anti-deflection rollers 63 are provided on both sides of the upper connection between the outer connecting plate 61 and the outer slider 42, the rolling core direction of the anti-deflection roller 63 is perpendicular to the moving direction of the outer slider 42, and the rim of the anti-deflection roller 63 is close to the outer plate surface of the top plate A2 of the sorting box A.

[0030] In the above scheme, anti-deflection rollers 63 are provided on both sides of the upper connection between the outer connecting plate 61 and the outer slider 42. Firstly, it can ensure that the outer slider 42 slides smoothly during the sliding process of the outer slider 42. Secondly, it can ensure that when the outer magnetic brush 20 is replaced, the anti-deflection rollers 63 keep the suspended end of the outer connecting plate 61 suspended in the air, ensuring that the suspended end of the outer connecting plate 61 will not contact the outer surface of the light-transmitting glass A1 of the sorting box A, thereby avoiding the suspension end of the outer connecting plate 61 from damaging the light-transmitting glass A1.

[0031] Further, such as Figures 7 to 9As shown, the inner fixing frame 52 includes support rods 521 arranged at a distance on the left and right, and the support rods 521 include a horizontal support plate 521a parallel to the surface where the light-transmitting glass A1 is located, and a vertical support plate 521b located at the lower part of the horizontal support plate 521a and forming an angular rod with the horizontal support plate 521a in cross section, and the vertical support plate 521b is provided with an internal bayonet 522, and the internal bayonet 522 includes a horizontal guide section 5221 and a vertical restraint section 5222 that are connected to each other. The horizontal guide section 5221 extends from the side plate edge of the vertical support plate 521b to the middle of the plate surface, and the horizontal guide section 5221 is parallel to the length direction of the vertical support plate 521b. The vertical constraint section 5222 extends to the side away from the horizontal support plate 521a. The inner magnetic brush 10 has an inner magnetic brush ear axis 11, and the inner magnetic brush ear axis 11 is located in the middle of the length direction of the inner magnetic brush 10. The inner magnetic brush ear axis 11 is clamped in the vertical constraint section 5222 of the internal bayonet 522.

[0032] In the above scheme, the support rods 521 arranged at left and right intervals are located on both sides of the inner magnetic brush 10. The inner magnetic brush 10 is provided with an inner magnetic brush ear axis 11. The inner magnetic brush ear axis 11 slides from the flat guide section 5221 parallel to the light-transmitting glass A1 and enters the vertical constraint section 5222. Since the length of the vertical constraint section 5222 matches the diameter of the inner magnetic brush ear axis 11, the circumferential displacement of the inner magnetic brush ear axis 11 is restricted, and the inner magnetic brush 10 can only be slightly displaced up and down perpendicular to the light-transmitting glass A1. When the inner magnetic brush 10 is slightly separated from the outer magnetic brush 20, since the inner magnetic brush 10 can only be slightly displaced up and down perpendicular to the light-transmitting glass A1, it will be attracted again under the action of magnetic force, thereby helping the outer magnetic brush 20 to effectively clean the light-transmitting glass A1.

[0033] Further, such as Figures 4 to 6 As shown, the external fixing frame 62 includes a support rod 621 arranged at a left and right interval, and the support rod 621 includes a cross-section angle rod composed of a horizontal strip plate 621a and a vertical strip plate 621b, wherein the horizontal strip plate 621a is parallel to the surface where the light-transmitting glass A1 is located, and the vertical strip plate 621b has a bayonet 622, and the bayonet 622 includes an oblique guide section 6221, a horizontal transition section 6222, and a vertical limit section 6223 that are connected to each other, and obliquely The guide section 6221 extends from the edge of the upright strip plate 621b to the middle of the plate surface, the horizontal transition section 6222 is parallel to the length direction of the upright strip plate 621b, the upright limiting section 6223 extends to the side where the horizontal strip plate 621a is located, and there is an outer magnetic brush ear axis 21 on the outer magnetic brush 20, and the outer magnetic brush ear axis 21 is located in the middle of the length direction of the outer magnetic brush 20, and the outer magnetic brush ear axis 21 is clamped in the upright limiting section 6223 of the bayonet 622.

[0034] In the above scheme, the outer fixing frame 62 includes a support rod 621 arranged at a left and right interval, the support rod 621 is located on both sides of the outer magnetic brush 20, the support rod 621 includes a horizontal strip plate 621a and a vertical strip plate 621b, the vertical strip plate 621b has a bayonet 622, the outer magnetic brush 20 has an outer magnetic brush ear shaft 21, along the oblique guide section 6221 of the bayonet 622, the horizontal transition section 6222, the vertical limit section 6223, and finally placed in the vertical limit section 6223, the vertical limit section 6223. The limiting section 6223 is perpendicular to the glass surface of the light-transmitting glass A1. Since the length of the vertical limiting section 6223 matches the diameter of the outer magnetic brush ear axis 21, the circumferential displacement of the outer magnetic brush 20 is restricted. Therefore, the outer magnetic brush ear axis 21 can only be slightly displaced up and down perpendicular to the light-transmitting glass A1 in the vertical limiting section 6223. Under the action of the magnetic force of the inner magnetic brush 10, the outer magnetic brush 20 is more closely attached to the surface of the light-transmitting glass A1, which helps to effectively clean the light-transmitting glass A1.

[0035] Preferably, a water spray pipe 90 is provided on the upper side of the light-transmitting glass A1 of the sorting machine box A, and an upper baffle 70 is provided on the upper part of the sorting machine box A. The rear part of the upper baffle 70 is connected to the sorting machine box A by a rubber cover 71.

[0036] In the above scheme, the water spray pipe 90 on the upper side of the light-transmitting glass A1 can wet the outer surface of the light-transmitting glass A1 and the outer magnetic brush 20, so as to facilitate the cleaning of oily or stubborn stains on the upper end of the light-transmitting glass A1. The upper part of the sorting machine box A is provided with an upper baffle 70, and the two side plates of the upper baffle 70 are connected with the side edges of the sorting machine box A. An air nozzle is fixed at the front of the middle part of the upper baffle 70, and the gas sprayed by the air nozzle forms a wind wall. The rear part of the upper baffle 70 is connected with the sorting machine box A for a rubber cover 7. 1, so the two side plates, the rubber cover 71 and the wind wall constitute four-sided protection, which can effectively prevent dust from entering and prevent dust from falling on the outer driving mechanism 40, ensuring that the outer driving mechanism 40 will not get stuck after working for a long time. Even if dust enters, because the connection between the rear part of the upper blocking cover 70 and the sorting machine box A is the rubber cover 71, it is only necessary to open the soft rubber cover 71 and use a blowing tool to clean the impurities entering the lower part of the upper blocking cover 70.
