[0011] Furthermore, the dust collection mechanism also includes a piston plate slidably connected to the inside of the dust collection box, a plurality of one-way air outlet valves are fixedly penetrated on the piston plate, a plurality of one-way air inlet valves are fixedly penetrated on one side of the dust collection box close to the cleaning wheel, and a filter plate is fixedly connected to the inner wall of the dust collection box.

[0012] Furthermore, anti-blocking mechanisms are provided on both sides of the dust box, and the anti-blocking mechanisms include a connecting rod rotatably connected to the side of the moving rod close to the sliding block one, and a limiting rod is fixedly connected to both sides of the dust box, and a sliding block 2 is slidably connected to the limiting rod, and the bottom of the sliding block 2 is rotatably connected to the connecting rod, and a pushing rod is fixedly connected to the top side wall of the sliding block 2, and the pushing rod slides through the side wall of the dust box, and a scraper is fixedly connected to the end of the push rod away from the sliding block 2, and one end of the scraper contacts the surface of the filter plate.

[0015] The present invention has the following beneficial effects:

[0016] When the crank rod pushes the sliding sleeve to slide along the sliding rod toward one end of the driving motor, the sliding block 1 on the sliding sleeve moves accordingly. When the toggle block on the sliding block 1 is pressed against the toggle plate, the toggle plate presses the sliding block 1 on the toggle block to press the return spring along the sliding sleeve. The sliding block 1 drives the piston plate at one end of the moving rod to move backward along the inner wall of the dust suction box. This arrangement is conducive to the one-way air outlet valve to extract the air inside the dust suction box, so that the dust suction box can suck the gas near the cleaning wheel into the dust suction box through the one-way air inlet valve. This arrangement is conducive to sucking the dust raised by the rotation of the flexible brush bristles into the dust suction box through the one-way air inlet valve, so as to prevent the dust from adhering to the surface of the packaging box cardboard again. The dust in the air entering the dust suction box adheres to the side of the filter plate close to the one-way air inlet valve. When the piston plate moves toward the side close to the one-way air inlet valve, the gas inside the dust suction box is discharged through the one-way air outlet valve. This arrangement is conducive to ensuring that the air discharged through the one-way air outlet valve remains clean.

[0017] (2) According to the present invention, when the packaging box printing detection device is used, the packaging box cardboard to be processed is first placed between the partition plates on the conveyor belt. At this time, the driving motor is started, and the output end of the driving motor rotates to drive the output shaft to rotate. The output shaft rotates to drive the conveyor belt to rotate. The conveyor belt rotates to drive the packaging box cardboard to move toward the bottom of the detection frame. The conveyor belt rotates to drive the rotating frame to rotate. The rotating frame rotates to drive the sliding sleeve at one end of the crank rod to slide along the sliding rod. At this time, when the sliding sleeve slides toward the end close to the driving motor, the sliding sleeve drives the cleaning shaft at one end of the connecting rod to move. The gear on the cleaning shaft meshes with the spur teeth. The gear drives the cleaning wheel on the cleaning shaft to rotate. The cleaning wheel drives the flexible bristles to rotate and wipe the packaging box cardboard directly above the conveyor belt. This arrangement is conducive to the flexible bristles to remove dust on the packaging box cardboard, which is conducive to the detection camera under the detection frame to detect the printed pattern on the packaging box cardboard, thereby improving the detection accuracy of the detection device.

[0018] (3) The present invention provides an anti-blocking mechanism. When the sliding block 1 drives the moving rod to move, the moving rod drives the sliding block 2 at one end of the connecting rod to move along the limiting rod toward the side wall of the dust collection box. At this time, the sliding block 2 drives the scraper at one end of the pushing rod to scrape the side of the filter plate where the dust is attached. This arrangement is conducive to timely cleaning of the dust on the filter plate, thereby ensuring that the dust collection mechanism in the device can operate normally and stably, and improving the dust collection efficiency of the dust collection mechanism in the device.

[0019] (4) In the present invention, a pressing mechanism is provided. When the conveyor belt drives the packaging box cardboard placed between the partition plates to move to the bottom of the connecting plate, the pressing wheels at the bottom of the telescopic rod press the two sides of the packaging box cardboard. Such a configuration is conducive to fixing the packaging box cardboard on the conveyor belt, thereby ensuring that the detection camera at the bottom of the detection frame can stably detect the packaging box; when the connecting rod drives the fixed column on the fixed rod to move, the movement of the fixed column drives the movement of the dust collection box, and the movement of the dust collection box drives the movement of the extrusion inclined plate on the side wall of the dust collection box. At this time, when the extrusion inclined plate is squeezed with the extrusion semicircular block on the top of the telescopic rod at the bottom, the telescopic rod squeezes the packaging box cardboard at the bottom of the pressing wheel downward. Such a configuration is conducive to preventing the flexible bristles from moving the packaging box when wiping the surface of the packaging box.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
