[0041] Figure 1 This is a structural diagram of a cleaning device according to an illustrative embodiment of the present invention.

[0042] The cleaning device according to the embodiments of this utility model, such as Figure 1As shown, the device includes a housing 12 and at least one set of brush rollers 14. The housing 12 has openings on its opposite sidewalls, serving as an input port for the input material and an output port for the output material. The set of brush rollers 14 includes at least one brush roller 14, which is positioned at the opening of the housing 12. The brush roller 14 is adapted to tightly abut against the surface of the material as it passes through the housing 12, and to rotate relative to the material, rubbing against it to adhere at least a portion of the debris from the surface of the material to the brush roller 14. A cavity is formed between the side of the brush roller 14 opposite to the material and the inner wall of the housing 12. This cavity is configured to communicate with an external suction device to create a negative pressure inside the cavity, suitable for adsorbing at least a portion of the debris that detaches from the surface of the material.

[0043] In this embodiment, the brush roller 14 of the cleaning device 1 is adapted to press tightly against the plate passing through the cleaning device 1 and rotate relative to it, so that at least a portion of the particles attached to the surface of the plate are swept off onto the brush roller 14.

[0044] In one illustrative embodiment, such as Figure 1 As shown, the housing 12 includes but is not limited to a structure that is constructed as a substantially cubic structure. In detail, the interior of the housing 12 is hollow, and the housing 12 is located on both sides of the central position (such as Figure 1 The input port and the output port are formed on the side wall of the plate (the left and right sides shown). Further, the size of the opening (i.e., the input port and the output port) is larger than the size of the plate (i.e., larger than the thickness of the plate (e.g., Figure 1 Dimensions shown in the up and down directions) and width (e.g.) Figure 1 The dimensions shown are oriented towards the paper surface to accommodate the passage of the sheet material.

[0045] In one illustrative embodiment, the cleaning device is equipped with a set of brush rollers 14, which includes a single brush roller 14. Specifically, the brush roller 14 is disposed on the upper side of the housing 12 between the inlet and the outlet, so as to press against the upper surface of the board when the board passes through the cleaning device, thereby cleaning the upper surface of the board.

[0046] In this implementation, the cleaning device 1 can be suspended above the conveying device 2 to clean the upper surface of the sheet metal passing through the conveying surface of the conveying device 2 without occupying factory space outside the conveying device 2.

[0047] In another illustrative embodiment, the cleaning device is equipped with multiple sets of brush rollers 14, which are arranged sequentially and at intervals from the inlet to the outlet. Specifically, each set of brush rollers 14 includes one brush roller 14. Furthermore, the multiple sets of brush rollers 14 are staggered in the horizontal direction (i.e., the brush rollers located in the upper part of the housing 12 are positioned above the gap between the two lower brush rollers 14; and the brush rollers located in the lower part of the housing 12 are positioned below the gap between the two upper brush rollers 14).

[0048] In this implementation, multiple sets of brush rollers 14 form a multi-level structure to progressively clean particles adhering to the upper and lower surfaces of the board. The bristle density of each set of brush rollers 14 can be configured to be the same or different (e.g., gradually increasing density from the inlet to the outlet) to more thoroughly clean particles adhering to the surface of the board.

[0049] In one illustrative embodiment, such as Figure 1 As shown, the two brush rollers 14 are adapted to divide the upper and lower parts of the housing 12 into two cavities (i.e., as shown in the diagram). Figure 1 (The first cavity 16 and the second cavity 19 are shown). Further, an air passage 11 with a generally trapezoidal cross-section is disposed within the housing 12 opposite to the first cavity 16 and / or the second cavity 19. The air passage 11 is connected to an external air extraction device (such as an air pump) to create a negative pressure in the first cavity 16 and the second cavity 19 away from the brush roller 14. Figure 1 The dotted line portion shown is provided with an openable cover (not shown in the figure) to seal the first cavity 16 and the second cavity 19 when the cover is closed at the dotted line position.

[0050] In this embodiment, when the brush roller 14 is pressed against the surface of the board, some particles (such as dust or processing debris) will adhere to the brush roller 14. Therefore, in the next rotation cycle of the brush roller, the particles may be re-adhered to the surface of the board. To address this, by providing a negative pressure environment in the first cavity 16 and the second cavity 19, the particles adhering to the brush roller 14 can be adsorbed to the outside of the cleaning device 4 through the air passage 11 in a state away from the board (such as the upper brush roller 14 facing upward), thereby preventing the particles from being re-adhered to the surface of the board.

[0051] According to the embodiment of the present utility model, Figure 1 As shown, a set of brush rollers 14 includes two brush rollers 4, which are arranged in parallel and spaced between the inlet and the outlet, and define a cleaning channel between the two brush rollers 14 to accommodate the passage of the board.

[0052] According to the embodiment of the present utility model, Figure 1As shown, at least one brush roller 14 in the same group is slidably mounted on the housing 12 so that one brush roller 14 can move between a proximity position close to another brush roller 14 and a distance position away from another brush roller 14 so that the thickness of the cleaning channel is adjustable.

[0053] In one illustrative embodiment, such as Figure 1 As shown, the cleaning device 1 includes a set of brush rollers 14. Specifically, the set of brush rollers 14 includes two brush rollers 14 arranged in parallel and spaced apart. Furthermore, a cleaning channel is defined between the two brush rollers 14, which is located between the inlet and outlet formed by the housing 12.

[0054] According to embodiments of the present invention, such as Figure 1 As shown, the side of the housing 12 is provided with a vertically extending groove. The cleaning device also includes a sliding mechanism, comprising multiple pairs of mounting seats 17, screws 15, and nuts. Two mounting seats 17 in each pair are symmetrically mounted at both ends of the axial direction of a brush roller 14 to mount the brush roller 14 in the groove, allowing the brush roller 14 to slide up and down along the groove. The screw 15 is vertically mounted between the mounting seat 17 and the housing 12. The end of the screw 15 connected to the mounting seat 17 is configured to rotate freely relative to the mounting seat 17, while the end of the screw connected to the housing 12 is configured to protrude through the housing 12. The nut is fitted onto the end of the screw 15 that protrudes from the housing and is threadedly engaged with the screw 15 to adjust the height of the mounting seat 17 or to hold the mounting seat 17 at a certain height.

[0055] In one illustrative embodiment, such as Figure 1 As shown, the side of the housing 12 (such as...) Figure 1 The side facing the paper and the side away from the paper (as shown) are provided with vertically oriented grooves. Furthermore, the mounting bases 17 are arranged in pairs, symmetrically installed within the grooves formed on the side of the housing 12. Even further, a screw 15 is disposed between the mounting base 17 and the housing 12. One end of the screw 15 that engages with the mounting base 17 (e.g., the lower end of the upper screw 15) is allowed to rotate freely, while the other end of the screw 15, and the end away from the mounting base 17 (e.g., the upper end of the upper screw 15) protrudes from the housing 12 (i.e., the upper end of the upper screw 15 protrudes from the upper part of the housing 12, and the lower end of the lower screw 15 protrudes from the lower part of the housing 12), and is threadedly engaged with an external nut (not shown in the figure).

[0056] In this embodiment, by turning the screw 15, the position of the brush roller 14 can be adjusted in the vertical direction, thereby adjusting the distance between the two brush rollers 14 so that the distance is suitable for the thickness of the board and so that the brush roller 14 rubs tightly against the board.

[0057] Figure 2This is a structural diagram of a transmission system according to an illustrative embodiment of the present invention.

[0058] The transmission system according to an embodiment of the present invention, such as Figure 2 As shown, it includes: a cleaning device and a conveying device 2. The conveying device 2 is located upstream and / or downstream of the cleaning device and is suitable for conveying sheet metal.

[0059] According to embodiments of the present invention, such as Figure 2 As shown, the conveying device 2 includes a first conveying section 21 and a second conveying section 22, and the cleaning device is disposed between the first conveying section 21 and the second conveying section 22.

[0060] In one illustrative embodiment, such as Figure 2 As shown, the conveying device 2 includes a first conveying section 21 and a second conveying section 22 arranged at intervals. Specifically, the first conveying section 21 and the second conveying section 22 have the same conveying direction (e.g., ...). Figure 2 (shown from top to bottom). The first conveyor 21 is adapted to receive plates output from an upstream process and convey them into the cleaning apparatus 1; the second conveyor 22 is adapted to receive plates output from the cleaning apparatus 1. Furthermore, the conveying surfaces of the first conveyor 21 and the second conveyor 22 are configured to be substantially the same height as the passage formed by the cleaning apparatus 1.

[0061] In one illustrative embodiment, such as Figure 2 As shown, the conveying device 2 has a conveying surface, suitable for conveying along a first direction (e.g., Figure 2 The conveying equipment 2 (shown from top to bottom) is used to transport the sheet metal. Specifically, the conveying equipment 2 includes, but is not limited to, belt conveyors, conveyor rollers, or any other conveying equipment suitable for transporting sheet metal.

[0062] In this implementation, the conveying device 2 is suitable for defining the conveying direction. The first conveying unit 21 is located upstream of the cleaning device and is suitable for feeding the board material into the input port of the cleaning device; the second conveying unit 22 is located downstream of the cleaning device and is suitable for receiving the board material conveyed from the input port of the cleaning device. In this way, the cleaning of the board surface is integrated into the conveying system, so that the cleaning of the board surface is integrated into the board conveying process, eliminating the need for additional steps.

[0063] According to embodiments of the present invention, such as Figure 2 As shown, the rotation direction of the brush roller 14 is configured to be opposite to the conveying direction of the sheet material conveyed by the conveying device 2.

[0064] In one illustrative embodiment, such as Figure 2As shown, the board is conveyed in a top-to-bottom direction, and the upper brush roller 14 is configured to rotate counterclockwise, while the lower brush roller 14 is configured to rotate clockwise, so that the brush roller 14 has a higher relative speed with respect to the board, thereby removing particles.

[0065] According to the embodiment of the present utility model, Figure 2 As shown, the conveying device 2 has a conveying surface that conveys the sheet material along a first direction. The bottom surface of the cleaning channel formed by the brush roller 14 of the cleaning device is at the same height as the conveying surface.

[0066] According to the embodiment of the present utility model, Figure 2 As shown, the conveying system also includes a pressing mechanism 13, which is disposed on the side of the cleaning device 1 facing the conveying device 3. The pressing mechanism 13 includes a pressure roller 133, which is configured to swing between an approach position close to the conveying surface of the conveying device 3 and a distance position away from the conveying surface, so that when it is in the approach position, it presses against the upper surface of the plate, thereby restricting the plate to the conveying surface.

[0067] According to the embodiment of the present utility model, Figure 2 As shown, the conveying system also includes a detection mechanism 18, which is communicatively connected to the top pressing mechanism 13. The detection mechanism 18 is suitable for retrieving the position of the plate relative to the channel formed by the brush roller 14, and for causing the top pressing mechanism 13 to swing the pressure roller 133 between the approach position and the away position in response to the position of the plate.

[0068] In one illustrative embodiment, such as Figure 1 and Figure 2 As shown, the pressing mechanism 13 includes, but is not limited to, a hinge 132, a pressure roller 133, and a cylinder 131. Specifically, one end of the hinge 132 is pivotally mounted on the outer wall of the housing 12 facing the conveying device 3, and the pressure roller 133 is rotatably mounted on the other end of the hinge. Further, the cylinder 131 is pivotally mounted between the outer wall of the conveying device 3 above the hinge and the hinge 132.

[0069] In one illustrative embodiment, such as Figure 1 and Figure 2 As shown, the detection mechanism 18 includes, but is not limited to, the use of a contact switch. Specifically, the detection end of the detection mechanism 18 is located as follows: Figure 1 On the outer wall of the housing 12 shown, the detection end of the detection mechanism 18 is suspended above the cleaning channel formed by the brush roller 14, as shown in the figure. Figure 2 In the left-right orthographic projection shown, the detection end of the detection mechanism 18 partially overlaps with the cleaning channel.

[0070] In this implementation, during the process of the board material entering the cleaning device 1 from the conveying device 2, or being output from the cleaning device 2 to the conveying device 2, the cylinder's outgoing stroke presses downward against the upper surface of the board material to prevent deviation in the conveying direction caused by the board material being partially raised by the conveying surface of the conveying device 2 during the rotation of the brush roller 14. When the board material leaves the cleaning device 4, the cylinder's return stroke moves upward, offsetting itself from the cleaning channel of the cleaning device 1 to avoid obstructing the input of the next board material. The outgoing and return strokes of the cylinder are controlled by an external detection mechanism 18. When the upper surface of the board material abuts against the detection mechanism 18, the detection mechanism (e.g., a contact switch) is triggered to control the timing of the action of the cylinder 131 on the same side. It should be understood that the embodiments of this utility model are not limited to this.

[0071] For example, the detection mechanism 18 may adopt a photoelectric sensor. Specifically, the detection end of the photoelectric sensor is located at the upper part of the shell 12, and the optical signal output end is located at the lower part of the shell 12, so as to block the light output by the optical signal output end when the plate passes through the cleaning channel, so that the optical signal at the detection end is blocked and thus triggered.

[0072] It should also be noted that the directional terms mentioned in the embodiments, such as "up," "down," "front," "back," "left," and "right," are only for reference to the directions in the accompanying drawings and are not intended to limit the scope of protection of this utility model. Throughout the drawings, the same elements are represented by the same or similar reference numerals. Conventional structures or constructions will be omitted where they may cause confusion in understanding this utility model.

[0073] The embodiments of the present invention have been described above. However, these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Although various embodiments have been described above, this does not mean that the measures in the various embodiments cannot be used advantageously in combination.
