The mounting plates 905 are fixedly installed inside the dust removal box 2. A second sliding groove 905a is provided on the mounting plate 905. The mounting blocks 906 are slidably installed in the second sliding groove 905a. The second screw 903 is rotatably installed in one of the second sliding grooves 905a through a bearing. The third motor 904 is fixedly installed on the dust removal box 2 and drives the second screw 903 to rotate. One of the mounting blocks 906 is threadedly connected to the second screw 903. The cleaning roller 901 is rotatably installed between the two mounting blocks 906 through a bearing. The second motor 902 is fixedly installed on one of the mounting blocks 906 and drives the cleaning roller 901 to rotate through an output shaft.

[0052] In use, the third motor 904 is turned on to drive the second screw 903 to rotate, and the second screw 903 drives the mounting block 906 to move up and down, thereby driving the cleaning roller 901 to move up and down. At the same time, the second motor 902 is turned on to drive the cleaning roller 901 to rotate. The cleaning roller 901 keeps rotating while moving up and down, so as to clean the surface of the paperboard 11. The cooperation of the mounting block 906 and the second sliding groove 905a plays a guiding and limiting role on the cleaning roller 901.

[0053] As shown in Figure 1 and 2 , in this embodiment, the dust collection assembly 10 includes a dust suction pipe 1001, a dust suction head 1002, a corrugated hose 1003, a suction fan 1004, and a dust collection box 1005. The dust suction pipe 1001 is fixedly arranged between the two mounting blocks 906 and is hollow. The dust suction head 1002 is communicatively arranged on the dust suction pipe 1001 and is close to the object seat 5. The corrugated hose 1003 is arranged between the inner top end of the dust removal box 2 and the dust suction pipe 1001 and is in communication with the dust suction pipe 1001. The suction fan 1004 and the dust collection box 1005 are both arranged on the dust removal box 2. The air inlet end of the suction fan 1004 is connected with the corrugated hose 1003, and the air outlet end of the suction fan 1004 is connected with the dust collection box 1005.

[0054] In use, the third motor 904 is turned on to drive the second screw 903 to rotate, and the second screw 903 drives the mounting block 906 to move up and down, thereby driving the cleaning roller 901 and the dust suction pipe 1001 to move up and down synchronously. At the same time, the suction fan 1004 is turned on, and the suction fan 1004 sucks the dust from the dust suction head 1002 into the dust suction pipe 1001. The dust is then transported to the dust collection box 1005 through the corrugated hose 1003 for collection, so as to collect the dust cleaned down. The dust suction pipe 1001 moves synchronously with the cleaning roller 901, so that the dust suction pipe 1001 is always close to the cleaning position, facilitating the collection of dust. The corrugated hose 1003 can stretch and contract with the up-and-down movement of the dust suction pipe 1001, so that the dust can be smoothly transported to the dust collection box 1005 through the corrugated hose 1003 when the dust suction pipe 1001 moves up and down.

[0055] As shown in Figure 2 and 4 , in this embodiment, the dust collection box 1005 is detachably provided with a filter screen 1005a. A limiting groove 1005b is formed in the dust collection box 1005, and the filter screen 1005a is inserted and fitted with the limiting groove 1005b. An air outlet pipe 1005c is communicatively arranged on the dust collection box 1005. The air inlet end of the dust collection box 1005 is divided into two sides of the filter screen 1005a, and the air outlet pipe 1005c is arranged on the two sides. A cover plate 1005d is arranged on the top of the dust collection box 1005, and a handle 1005e is arranged on the cover plate 1005d.

[0056] In use, the air flow generated by the air extractor 1004 enters the dust collection box 1005 and is discharged from the air outlet pipe 1005c, while the dust is blocked by the filter screen 1005a; the filter screen 1005a is cleaned regularly, the handle 1005e is pulled to open the cover plate 1005d, and then the filter screen 1005a is taken out of the dust collection box 1005 for cleaning; regular cleaning of dust, paper scraps and other impurities attached to the filter screen 1005a can prevent the filter screen 1005a from being blocked and ensure the dust collection efficiency; the limiting groove 1005b supports and limits the filter screen 1005a.

[0057] As shown in Figures 1 to 3 In this embodiment, the suction head 701 is provided with a plurality of suction heads 701, which are evenly distributed in the storage groove 501; the dust collection head 1002 is provided with a plurality of dust collection heads 1002, which are evenly distributed on both sides of the dust collection pipe 1001.

[0058] The evenly distributed plurality of suction heads 701 make the paperboard 11 more stable and reliable to be adsorbed and fixed in the storage groove 501 on the storage seat 5, improving the use stability; the evenly distributed plurality of dust collection heads 1002 can expand the dust collection range and improve the dust collection effect.

[0059] In this embodiment, the cleaning roller 901 is made of velvet cloth material; the velvet cloth material can more effectively adsorb and capture the dust on the surface of the paperboard 11 due to its dense and soft pile on the surface, thereby ensuring the cleanliness of the surface of the paperboard 11; the soft texture of the velvet cloth can avoid causing scratches or damage to the surface of the paperboard 11 during cleaning, which is beneficial to maintaining the flatness and integrity of the surface of the paperboard 11 and ensuring product quality.

[0060] Working principle: when the paperboard dust removal device of the paperboard printing machine provided in the application is in use, the two storage seats 5 are in a separated state, the paperboard 11 to be dusted is placed in the storage groove 501 on one of the storage seats 5 at the feeding position, and the suction head 701 of the storage seat 5 is driven by an external vacuum pump to adsorb and fix the paperboard 11 on the storage seat 5, then the first motor 402 is started to drive the first screw 401 to rotate, the first screw 401 drives the mounting seat 3 to move, thereby driving the storage seat 5 to move into the dust removal box 2;

[0061] Subsequently, the third motor 904 is started to drive the second screw rod 903 to rotate, the second screw rod 903 drives the mounting block 906 to move up and down, thereby driving the cleaning roller 901 and the dust suction pipe 1001 to move up and down synchronously, at the same time, the second motor 902 is started to drive the cleaning roller 901 to rotate, the cleaning roller 901 keeps rotating while moving up and down, thereby cleaning the surface dust of one side of the paperboard 11, at the same time, the air extractor 1004 is started to suck the dust from the dust suction head 1002 into the dust suction pipe 1001, the dust is then transported from the corrugated hose 1003 to the dust collecting box 1005 for collection, thereby collecting the cleaned dust, then the cleaning roller 901 and the dust suction pipe 1001 are reset, then the first air cylinder 601 is started to drive the storage seat 5 to move, thereby driving the two storage seats 5 to combine together, then the second air cylinder 801 is started to drive the push plate 802 to move, the push plate 802 enters the storage groove 501 and pushes the paperboard 11 from one storage seat 5 to the other storage seat 5, at the same time, the adsorption of the adsorption assembly 7 of the storage seat 5 is stopped, and the paperboard 11 is adsorbed and fixed on the other storage seat 5 by the adsorption assembly 7 of the other storage seat 5, then the two storage seats 5 are separated by the combining and separating assembly 6, at the same time, the surface dust of the other side of the paperboard 11 is cleaned by the dust cleaning assembly 9, and the cleaned dust is collected by the dust collecting assembly 10.

[0062] Subsequently, the mounting seat 3 and the storage seat 5 are moved to the dust collecting box 2 by the conveying assembly 4, the paperboard 11 on which the dust cleaning operation is completed is taken away from the other storage seat 5 at the discharging position, so as to be subjected to subsequent printing operation.
