Detailed implementation mode

[0020] The following will further elaborate on this application in conjunction with the attached Figures 1 - 4 drawings.

[0021] An embodiment of this application discloses a dust removal device for a printing device. Referring to Figure 1 、 Figure 2 、 Figure 3 , a dust removal device for a printing device includes a cuboid-shaped first support plate 1, and two plate-shaped mounting plates 2 are fixedly connected to the upper surface of the first support plate 1. Mounting holes are penetrated through the side surfaces of the mounting plates 2 so that the mounting plates 2 can be fixed to the inner side wall of the printing device by screws, making this device located above the conveyor belt for dust removal. A plate-shaped first connecting plate 31 in the shape of an L and a plate-shaped second connecting plate 32 in the shape of an L are slidably connected to the lower surface of the first support plate 1, and a plate-shaped second support plate 4 is fixedly connected to the lower surfaces of the first connecting plate 31 and the second connecting plate 32. Two block-shaped connecting blocks 5 are fixedly connected to the lower surface of the second support plate 4. A rod-shaped brush rod 6 is snap-connected to the opposite side surfaces of the two connecting blocks 5. A box-shaped first dust suction chamber 7 and a box-shaped second dust suction chamber 8 are fixedly connected to the lower surface of the second support plate 4 on both sides of the brush rod 6. When dust removal is required, the second support plate 4 is driven to slide downward through the first connecting plate 31 and the second connecting plate 32, so that the brush rod 6 contacts the surface of the conveyor belt. When the conveyor belt rotates past the lower part of this device, first, the dust on the conveyor belt is adsorbed by the first dust suction chamber 7, then the residual dust and other substances attached to the surface of the conveyor belt are brushed off by the connecting blocks 5, and then the scraped-off matter and the raised dust are adsorbed by the second dust suction chamber 8, thus completing the dust removal work of the conveyor belt of the printing device. This can not only improve the dust suction efficiency but also prevent the raised dust from flying into the surrounding environment and endangering the health of the staff. Secondly, a cuboid cavity-shaped negative pressure chamber 9 is fixedly connected to the upper surface of the first support plate 1. A tubular first conveying pipe 10 is fixedly connected to the upper surface of the negative pressure chamber 9, and the other end of the first conveying pipe 10 is fixedly connected to the side surface of the first dust suction chamber 7. A tubular second conveying pipe 11 is fixedly connected to the outer surface of the first conveying pipe 10, and the other end of the second conveying pipe 11 is fixedly connected to the side surface of the second dust suction chamber 8. Under the negative pressure action of the negative pressure chamber 9, the dust and residues are absorbed by the first dust suction chamber 7 and the second dust suction chamber 8, and then conveyed to the inside of the negative pressure chamber 9 through the first conveying pipe 10 and the second conveying pipe 11 for subsequent centralized treatment.

[0022] Referring to Figure 3, a groove-shaped first sliding groove 12 is formed on the lower surface of the first support plate 1. A columnar limiting column 13 is fixedly connected to the inner wall of the first sliding groove 12, and the outer surface of the limiting column 13 slides relative to the second connecting plate 32. Secondly, a groove-shaped second sliding groove 14 is formed on the lower surface of the first support plate 1. A ball screw 15 is rotatably connected to the inner wall of the second sliding groove 14, and the outer surface of the ball screw 15 is screwed relative to the first connecting plate 31. A motor 16 is fixedly connected to the upper surface of the first support plate 1. The upper surface of the ball screw 15 penetrates through the first support plate 1 to its upper surface and is fixedly connected to the output end of the motor 16. So that under the limiting action of the limiting column 13, the ball screw 15 is driven to rotate by the motor 16, so that the first connecting plate 31 and the second connecting plate 32 drive the second support plate 4 to slide up and down. So that when dust removal is required, the second support plate 4 can slide downward until the brush rod 6 contacts the surface of the conveyor belt. When the device is not needed, the second support plate 4 can be driven to slide upward, so that the brush rod 6, the first dust suction chamber 7, and the second dust suction chamber 8 are away from the conveyor belt, avoiding affecting the printing work.

[0023] Refer to Figure 4 , groove-shaped clamping grooves 17 are formed on both side surfaces of the brush rod 6. Groove-shaped limiting grooves 18 are formed on the side surfaces of the two connecting blocks 5. A block-shaped limiting block 19 is elastically slidably connected to the inner wall of the limiting groove 18 through a spring, and the limiting block 19 can be engaged with the inner wall of the clamping groove 17. So that by pressing the limiting block 19, it contracts into the inner wall of the limiting groove 18, and then the brush rod 6 is slid downward for removal, so that it can be replaced after being used for a period of time. When installing a new brush rod 6, by pressing the limiting block 19, it contracts into the inner wall of the limiting groove 18. At this time, the spring is in a compressed state, and then the brush rod 6 is slid upward between the two connecting blocks 5. Then after the external force disappears, the limiting block 19 rebounds under the reset action of the spring and is engaged with the inner wall of the clamping groove 17, thereby stably fixing the brush rod 6, thus facilitating the quick disassembly and assembly of the brush rod 6 and ensuring the dust removal effect.

[0024] The implementation principle of a dust removal device for a printing device in an embodiment of the present application is as follows: During use, first, the mounting plate 2 is fixed to the inner wall of the printing device by screws, such that the device is located at a position with a certain distance above the conveyor belt. Then, under the limiting action of the limiting posts 13, the motor 16 drives the ball screw 15 to rotate, so that the first connecting plate 31 and the second connecting plate 32 drive the second support plate 4 to slide downward, causing the second support plate 4 to slide downward until the brush rod 6 contacts the surface of the conveyor belt. When the conveyor belt rotates past the device below, under the negative pressure of the negative pressure chamber 9, first, the first dust suction chamber 7 adsorbs the dust on the conveyor belt, and then the connecting block 5 brushes off the residual dust and the like attached to the surface of the conveyor belt. Then, the second dust suction chamber 8 adsorbs the scraped-off matter and the raised dust. The dust and residues adsorbed by the first dust suction chamber 7 and the second dust suction chamber 8 are transported to the inside of the negative pressure chamber 9 through the first conveying pipe 10 and the second conveying pipe 11 for centralized placement, thereby completing the dust removal work of the conveyor belt of the printing device. This device can not only improve the dust removal efficiency but also prevent the raised dust from flying into the surrounding environment, ensuring the physical health of the staff.
