[0002] Color sorter is a device that uses photoelectric detection technology to automatically sort out different-colored particles in granular materials according to the difference in optical properties of the materials. Color sorter mainly includes the following parts: material detection system, control drive system, light system and air blowing system, among which the material detection system and light source system are the most core parts, and the cleanliness of the light-transmitting glass surface in the light source system is particularly important. In order to maintain the cleanliness of the light-transmitting glass surface, a glass dust cleaning device is used.

[0003] The document entitled “A device for cleaning translucent glass of a color sorter (document number CN203470367U)” discloses a device for cleaning translucent glass, which mainly uses a floating support provided by an elastic support unit arranged on the brush body to form a fine-tuning fit with the brush surface of the translucent glass bristles to improve the fit between the two, thereby improving the cleaning effect; in the above scheme, the second bracket is installed on one side of the first bracket, and one end of the second bracket is in a cantilevered state. At this time, the second bracket is equivalent to a cantilever beam structure. During the process of wiping the translucent glass with the brush, the second bracket is prone to tilt, resulting in the brush installed on the second bracket being unable to fully fit the surface of the translucent glass, and the dust on the surface of the translucent glass is difficult to remove, thereby reducing the cleaning effect on the surface of the translucent glass. Summary of the invention

[0004] The object of the present invention is to provide a dust cleaning device, which ensures the cleaning effect by making the brush surface of the cleaning brush completely fit with the surface of the light-transmitting glass.

[0005] The present invention can be implemented through the following technical scheme: a cleaning device, a cleaning brush is connected to a connecting arm, the connecting arm is connected to a displacement driving mechanism, the displacement driving mechanism drives the connecting arm to move linearly in a direction that is arranged at an angle to the brush length direction of the cleaning brush, the two ends of the connecting arm are connected to a first roller and a second roller, the first roller and the second roller respectively roll and move along the surface of a frame plate, and the surface of the frame plate is parallel to the direction of the linear displacement of the connecting arm.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] By arranging the first roller and the second roller at both ends of the connecting arm, and with the help of the constraints provided by the frame plate on the first roller and the second roller, a stable and reliable limit is imposed on the posture of the connecting arm during operation to prevent the connecting arm from deflecting, thereby ensuring the uniformity and stability of the brush surface of the cleaning brush and the glass surface to be cleaned, thereby ensuring the cleaning effect of the glass surface to be cleaned.

[0014] See also Figure 1-6 As shown, a dust cleaning device is shown, the dust cleaning brush 30 is connected to the connecting arm 10, and the connecting arm 10 is connected to the displacement driving mechanism 20, the displacement driving mechanism 20 drives the connecting arm 10 to move linearly in a direction that is arranged at an angle with the brush length direction of the dust cleaning brush 30, and the two ends of the connecting arm 10 are connected to the first roller 40 and the second roller 50, and the first roller 40 and the second roller 50 respectively roll and move along the surface of the frame plate 60, and the surface of the frame plate 60 is parallel to the direction of the linear displacement of the connecting arm 10; whether the displacement driving mechanism 20 is arranged at the two ends of the connecting arm 10 or in the middle position of the connecting arm 10, it may cause the dust cleaning brush 30 on the connecting arm 10 to fail to fit with the glass surface A to be cleaned, thereby resulting in the problem that dust cannot be cleaned off. The present application achieves this by connecting the connecting arm 10 to the glass surface A to be cleaned. A first roller 40 and a second roller 50 are provided at both ends of the arm 10. When the displacement driving mechanism 20 drives the connecting arm 10 to displace, the first roller 40 and the second roller 50 roll along the surface of the frame plate 60 in cooperation. Since the frame plate 60 is a component on the frame independent of the connecting arm 10 and the displacement driving mechanism 20, the frame plate 60 itself has sufficient rigidity and position stability. Therefore, with the help of the constraints provided by the frame plate 60 to the first roller 40 and the second roller 50, a stable and reliable limit is imposed on the posture of the connecting arm 10 during operation, preventing the connecting arm 10 from deflecting, thereby ensuring that the brush surface of the cleaning brush 30 is evenly and stably fitted with the glass surface A to be cleaned, thereby ensuring the cleaning effect of the glass surface A to be cleaned.

[0015] Furthermore, the frame plate 60 includes a first plate 61 and a second plate 62, and the first plate 61 and the second plate 62 are arranged at an angle, and the extension surface of the glass surface A to be cleaned intersects with the extension surfaces of the first plate 61 and the second plate 62; the frame plate 60 can be a plate already existing on the color sorter body, or a plate added to the color sorter body; in the present application, the glass surface A to be cleaned is arranged at an angle, and the first plate 61 on which the first roller 40 relies can be in the horizontal plane direction or inclined, and the second plate 62 on which the second roller 50 relies can be in the plumb plane direction or inclined. It should be noted that when the first plate 61 and the second plate 62 need to be set independently, it should be considered that their setting positions do not affect the normal operation of the optical components.

[0016] The first roller 40 is connected to the axle 411 at the fork end of the roller fork rod 41, and the rod section of the roller fork rod 41 away from the roller 40 is placed in the closed blind hole 421 of the roller support 42, and the rod end of the roller fork rod 41 located in the large-diameter section of the closed blind hole 421 is a T-shaped head convex plate 412, and a compression spring 43 is arranged between the convex plate 412 and the bottom of the closed blind hole 421. The middle section of the roller fork rod 41 is a non-circular section that matches the aperture of the closed blind hole 421, and the roller support 42 is connected to the connecting arm 10; the connection and support structure of the first roller 40 and the second roller 50 are the same; the non-circular cross section refers to a straight, square, semicircular, The cross-sectional profile is shaped like a circle or an arch, and the non-circular cross-section can prevent the roller fork rod 41 from rotating in the closed blind hole 421, thereby ensuring that the wheel cores of the first roller 40 and the second roller 50 are perpendicular to the displacement direction of the displacement driving mechanism 20, and the wheel cores of the first roller 40 and the second roller 50 are parallel to the first plate 61 and the second plate 62 respectively; the compression spring 43 provides elastic force to make the first roller 40 and the second roller 50 contact the plate surface of the frame plate 60 respectively, so that the direction of the resultant force at the two ends of the connecting arm 10 is perpendicular to the glass surface A to be cleaned, so that the brush surface of the cleaning brush 30 is completely in contact with the glass surface A to be cleaned and the pressing force at various locations is uniform, thereby finally ensuring the cleaning effect of the glass surface A to be cleaned.

[0017] In the above, the outside of the roller support 42 is provided with an external thread, and the connecting arm 10 is provided with a through hole for the roller support 42 to pass through. When the roller support 42 is installed on the connecting arm 10, one end of the roller support 42 is first passed through the through hole, and then nuts are screwed into the roller support 42 located on both sides of the through hole, so that the two nuts are respectively against the two sides of the connecting arm 10, thereby fixing the roller support 42.

[0018] Preferably, the direction in which the displacement drive mechanism 20 drives the connecting arm 10 to linearly displace is perpendicular to the brush length direction of the cleaning brush 30; such a setting can increase the cleaning area of ​​the cleaning brush 30 when wiping the glass surface A to be cleaned, thereby giving full play to the effect of the brush length of the cleaning brush 30.

[0019] The connecting arm 10 includes a cleaning brush fixing plate 11 parallel to the glass surface A to be cleaned, the top of the cleaning brush fixing plate 11 is connected to a first roller fixing plate 12 upwardly, and the bottom of the cleaning brush fixing plate 11 is connected to a second roller fixing plate 13 downwardly, and the cleaning brush fixing plate 11 is arranged at an angle to the first roller fixing plate 12 and the second roller fixing plate 13 respectively; wherein the second roller fixing plate 13 is an angular plate structure, and the second roller 50 is installed on the vertical plate of the second roller fixing plate 13, so that the second roller 50 can be in a horizontal state or a nearly horizontal state, that is, the rotating surface of the second roller 50 is in a horizontal plane or is arranged at a small angle to the horizontal plane; the rotating surface of the first roller 40 is in a plumb plane or is arranged at a small angle to the plumb plane; in the present application, the specific shape of the connecting arm 10 can also be adaptively adjusted according to the position and posture of the glass surface A to be cleaned.

[0020] A pin 71 perpendicular to the brush surface of the cleaning brush 30 is connected to the cleaning brush 30, and an introduction slide 111 consistent with the movement direction of the displacement drive mechanism 20 and a limiting slide 112 perpendicular to the movement direction of the displacement drive mechanism 20 are provided on the plate surface of the cleaning brush fixing plate 11. One end of the introduction slide 111 is connected to the limiting slide 112, and the other end of the introduction slide 111 extends to the side of the connecting arm 10 to form a notch for guiding the pin 71 into the introduction slide 111; a spring 72 is sleeved on the outside of the pin 71, and one end of the spring 72 is fixed to the cleaning brush 30, and the other end rests on the plate surface of the connecting arm 10; wherein, preferably two pins 71 are provided, and each pin 71 is provided with a spring 72; when the cleaning brush 30 is installed on the connecting arm 10, in the movement direction of the displacement drive mechanism 20 The pin 71 on one side of the cleaning brush 30 is inserted into the introduction slide 111 from the notch of the introduction slide 111 in a posture perpendicular to the surface of the cleaning brush fixing plate 11, and is pushed to the lower position of the limiting slide 112. At this time, the limiting slide 112 limits the displacement of the cleaning brush 30 along the movement direction of the displacement driving mechanism 20, and the spring 72 is compressed between the cleaning brush 30 and the cleaning brush fixing plate 11. The spring 72 provides elastic force to drive the brush surface of the cleaning brush 30 to fit against the glass surface A to be cleaned, thereby ensuring the cleaning effect of the glass surface A to be cleaned; at the same time, this installation scheme of installing the cleaning brush 30 on the connecting arm 10 has low requirements on the operating space. Even if the distance between the connecting arm 10 and the glass surface A to be cleaned is small, the cleaning brush 30 can be easily installed on the connecting arm 10.

[0021] The cleaning brush 30 is fixed on the mounting plate 73, and one end of the pin 71 is fixed to the surface of the mounting plate 73. The setting of the mounting plate 73 provides a more stable surface for the cleaning brush 30, which facilitates the connection of the pin 71. The mounting plate 73 and the cleaning brush 30 can be connected by bolts. When replacing the cleaning brush 30, only the cleaning brush 30 needs to be replaced, and there is no need to replace the mounting plate 73 and the pin 71.

[0022] The displacement driving mechanism 20 is a rodless cylinder, one side of the first roller fixing plate 12 is connected to the slider of the rodless cylinder, and two groups of brushes 80 are arranged in the area of ​​the rodless cylinder for the first roller fixing plate 12 to pass through, and the two groups of brushes 80 respectively abut against the upper and lower side surfaces of the first roller fixing plate 12; since dust will be generated above the glass surface A to be cleaned, the dust will move to the area of ​​the rodless cylinder for the first roller fixing plate 12 to pass through and affect the sliding of the first roller fixing plate 12 in the area. In order to avoid this phenomenon, two groups of brushes 80 are arranged to clean the surface of the first roller fixing plate 12 to ensure the normal sliding of the first roller fixing plate 12.
