Description

Technical Field

[0001] This utility model relates to the field of dust removal technology for color sorters, specifically a dust removal device. Background Technology

[0002] A color sorter is a device that automatically separates discolored particles from granular materials based on differences in their optical properties using photoelectric detection technology. A color sorter mainly consists of the following parts: a material detection system, a control and drive system, a light system, and an air blowing system. Among these, the material detection system and the light source system are the most crucial components, and the cleanliness of the light-transmitting glass surface in the light source system is particularly important. A glass cleaning device is used to maintain the cleanliness of the light-transmitting glass surface.

[0003] A device for cleaning transparent glass, entitled "A Color Sorter Transparent Glass Cleaning Device (Document No. CN203470367U)," discloses a transparent glass cleaning device. It mainly improves the cleaning effect by using a floating support provided by an elastic support unit on the brush body to create a fine-tuning fit between the brush and the transparent glass brush surface. However, in this design, a second bracket is installed on one side of the first bracket, with one end of the second bracket in a cantilevered state. This makes the second bracket, equivalent to a cantilever beam structure, prone to tilting during the brush's cleaning of the transparent glass. This causes the brush mounted on the second bracket to fail to fully adhere to the transparent glass surface, making it difficult to remove dust and thus reducing the cleaning effect on the transparent glass surface. Utility Model Content

[0004] The purpose of this invention is to provide a dust removal device that ensures cleaning effectiveness by making all parts of the cleaning brush completely adhere to the surface of the translucent glass.

[0005] This utility model can be achieved through the following technical solution: a dust removal device, wherein a dust removal brush is connected to a connecting arm, the connecting arm is connected to a displacement driving mechanism, the direction of linear displacement of the connecting arm driven by the displacement driving mechanism is arranged at an angle to the brush length direction of the dust removal brush, and 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 the frame plate, and the surface of the frame plate is parallel to the direction of linear displacement of the connecting arm.

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

[0007] By setting first and second rollers at both ends of the connecting arm, and by using the constraints provided by the frame plate on the first and second rollers, a stable and reliable limit is applied to the posture of the connecting arm during operation, preventing the connecting arm from deflecting. This ensures that the brush surface of the cleaning brush adheres evenly and reliably to the glass surface to be cleaned, thereby guaranteeing the cleaning effect on the glass surface to be cleaned.

[0014] Please see Figure 1-6 As shown, a dust removal device includes a dust removal brush 30 connected to a connecting arm 10. The connecting arm 10 is connected to a displacement drive mechanism 20. The direction of linear displacement of the connecting arm 10 driven by the displacement drive mechanism 20 is at an angle to the length direction of the dust removal brush 30. A first roller 40 and a second roller 50 are connected to both ends of the connecting arm 10. The first roller 40 and the second roller 50 roll along the surface of a frame plate 60, and the surface of the frame plate 60 is parallel to the direction of linear displacement of the connecting arm 10. Whether the displacement drive mechanism 20 is located at either end of the connecting arm 10 or in the middle, it may cause the dust removal brush 30 on the connecting arm 10 to not adhere to the glass surface A to be cleaned, resulting in dust that cannot be removed. This application addresses this issue by connecting... The two ends of the arm 10 are provided with a first roller 40 and a second roller 50. When the displacement drive mechanism 20 drives the connecting arm 10 to move, the first roller 40 and the second roller 50 roll along the surface of the frame plate 60. Since the frame plate 60 is a component on the frame that is independent of the connecting arm 10 and the displacement drive mechanism 20, the frame plate 60 itself has sufficient rigidity and positional stability. Thus, with the help of the constraint conditions provided by the frame plate 60 on the first roller 40 and the second roller 50, a stable and reliable limit is applied to the posture of the connecting arm 10 during operation, preventing the connecting arm 10 from deflecting. This ensures that the brush surface of the cleaning brush 30 is evenly and reliably attached to 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, which are arranged at an angle. 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 that already exists on the body of the color sorter, or it can be a plate added to the body of the color sorter. In this application, the glass surface A to be cleaned is arranged at an angle. The first plate 61 on which the first roller 40 rests can be in the horizontal direction or at an angle. The second plate 62 on which the second roller 50 rests can be in the vertical direction or at an angle. It should be noted that when the first plate 61 and the second plate 62 need to be set independently, their positions should be designed so as not to 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 41. The section of the roller fork 41 away from the roller 40 is placed inside the constricted blind hole 421 of the roller support 42. The end of the roller fork 41 located in the large-diameter section of the constricted blind hole 421 is a T-shaped cam 412. A compression spring 43 is provided between the cam 412 and the bottom of the constricted blind hole 421. The cross-section of the middle section of the roller fork 41 is a non-circular cross-section that matches the diameter of the constricted end of the constricted blind hole 421. 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, or semi-circular cross-section. The cross-sectional profile is either round or arched. The non-circular cross-section can prevent the roller fork 41 from rotating in the constricted blind hole 421, ensuring that the wheel cores of the first roller 40 and the second roller 50 are perpendicular to the displacement direction of the displacement drive mechanism 20, and that 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 so that the first roller 40 and the second roller 50 contact the plate surface of the frame plate 60, so that the resultant force at both 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 pressure is uniform everywhere, ultimately ensuring the cleaning effect of the glass surface A to be cleaned.

[0017] As described above, the roller support 42 is provided with external threads, 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 supports 42 located on both sides of the through hole, so that the two nuts abut against both sides of the connecting arm 10, thereby fixing the roller support 42.

[0018] Preferably, the direction of linear displacement of the drive arm 10 driven by the displacement drive mechanism 20 is perpendicular to the brush length direction of the cleaning brush 30; this setting can increase the cleaning area of ​​the cleaning brush 30 when wiping the glass surface A to be cleaned, thereby making full use 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. A first roller fixing plate 12 extends upward from the top of the cleaning brush fixing plate 11, and a second roller fixing plate 13 extends downward from the bottom of the cleaning brush fixing plate 11. 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. The second roller fixing plate 13 has an angled plate structure. The second roller 50 is mounted on the upright plate of the second roller fixing plate 13, so that the second roller 50 can be in a horizontal or nearly horizontal state, that is, the rotation surface of the second roller 50 is horizontal or at a small angle to the horizontal plane. The rotation surface of the first roller 40 is plumb or at a small angle to the plumb plane. In this 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. The cleaning brush fixing plate 11 has an inlet slide 111 aligned 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. One end of the inlet slide 111 communicates with the limiting slide 112, and the other end extends to the side of the connecting arm 10, forming a notch for guiding the pin 71 into the inlet slide 111. A spring 72 is sleeved on the outside of the pin 71, with one end fixed to the cleaning brush 30 and the other end abutting against the plate surface of the connecting arm 10. Preferably, two pins 71 are provided, and each pin 71 is equipped 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 guide slide 111 through the notch of the guide slide 111 in a posture perpendicular to the surface of the cleaning brush fixing plate 11, and pushed to the lower position of the limiting slide 112. At this time, the limiting slide 112 restricts the cleaning brush 30 from moving along the direction of movement of the displacement drive mechanism 20, while 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 onto the connecting arm 10 has low requirements for 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 onto 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 on the surface of the mounting plate 73. The mounting plate 73 provides a more stable surface for the cleaning brush 30, making it easier to connect 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, without replacing the mounting plate 73 and the pin 71.

[0022] The displacement drive mechanism 20 is a rodless cylinder. One side of the first roller fixing plate 12 is connected to the slider of the rodless cylinder. Two sets of brushes 80 are provided on the rodless cylinder in the area through which the first roller fixing plate 12 passes. The two sets of brushes 80 abut against the upper and lower sides of the first roller fixing plate 12 respectively. Since dust will be generated above the glass surface A to be cleaned, this dust will move to the area through which the first roller fixing plate 12 passes on the rodless cylinder and affect the sliding of the first roller fixing plate 12 in this area. To avoid this phenomenon, two sets of brushes 80 are provided to clean the surface of the first roller fixing plate 12 and ensure the normal sliding of the first roller fixing plate 12.
