[0002] A carton printing machine is a printing device that can print the required text, patterns and other information on the surface of the carton body. It generally includes processes such as plate mounting, ink coating, imprinting, and paper feeding. Most of the existing cardboard printing is carried out in the form of a production line, with high efficiency. The conveyor belt is a key device for conveying cardboard. Whether it is feeding or adjusting the printing position, the conveyor belt is required to cooperate. However, when the cardboard is conveyed by the conveyor belt, the paper scraps and shredded paper floating in the air are likely to fall on the cardboard, and the paper scraps and shredded paper will have an adverse impact on printing, resulting in problems such as missing printing and unclear printing.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Please refer to Figures 1-5 , the present invention provides a technical solution: a cardboard printing device for carton production, including a belt conveyor 1 and a printing press 2. The printing press 2 is erected on the belt conveyor 1, and a cleaning mechanism 3 is arranged on the right side of the printing press 2;

[0023] The cleaning mechanism 3 includes a mounting frame 301 and a dust suction pump 306. The mounting frame 301 is fixedly installed on the top of the frame of the belt conveyor 1. A motor 302 is fixedly installed on the inner wall of the mounting frame 301. The output end of the motor 302 is fixedly installed with a rotating shaft 303. A cleaning brush 304 is fixedly sleeved on the outer wall of the rotating shaft 303. The cleaning brush 304 is located above the belt conveyor 1. The air inlet end of the dust suction pump 306 is communicated with a filter box 309 through a pipeline. The back of the filter box 309 is communicated with a dust suction head 305 through a pipeline. The air outlet end of the dust suction pump 306 is communicated with a diverging pipe 307 through a pipeline. The front of the diverging pipe 307 is communicated with a first air blowing head 308 through a pipeline. The dust suction head 305 and the first air blowing head 308 are symmetrically distributed about the center of the belt conveyor 1 in the front and back directions. The cleaning brush 304 is close to the right end of the dust suction head 305 and the first air blowing head 308. The motor 302 drives the rotating shaft 303 to rotate, thereby driving the cleaning brush 304 to rotate. The cleaning brush 304 brushes off the residual paper scraps on the cardboard. The dust suction pump 306 works to pump air into the filter box 309. Under the action of the air pressure difference, a negative pressure is formed at the dust suction head 305, and then the paper scraps and dust brushed off by the cleaning brush 304 are sucked into the dust suction head 305 and then into the filter box 309. At the same time, the blowing air flow generated by the operation of the dust suction pump 306 enters the first air blowing head 308 from the diverging pipe 307 and then blows onto the cardboard from the first air blowing head 308, forming a stable air flow channel, thereby improving the removal effect of paper scraps and dust;

[0024] A guide component 4 is fixedly installed on the top of the frame of the belt conveyor 1 to guide the paperboard and ensure that the paperboard is conveyed to the printing press 2 along the set position;

[0025] A filter screen 3091 is fixedly installed on the inner wall of the filter box 309, and a box door 3092 is provided on the front of the filter box 309. The filter screen 3091 is provided to filter paper scraps and dust in the air flow, and the box door 3092 is provided to close the filter box 309 and remove paper scraps and dust in the filter box 309;

[0026] The guide component 4 includes an L-shaped plate 401, which is fixedly installed on the top of the frame of the belt conveyor 1. An adjusting rod 402 is slidably provided on the inner wall of the L-shaped plate 401. A guide plate 403 is fixedly installed on one end of the adjusting rod 402 facing the belt conveyor 1. The adjusting rod 402 is installed through the L-shaped plate 401, and the position of the guide plate 403 is adjusted through the adjusting rod 402, thereby ensuring that the guide plate 403 can guide the paperboard;

[0027] The front of the shunt pipe 307 is connected to a blow head 2 9 through a pipeline. The blow head 2 9 is located on the left side of the blow head 1 308. The openings of the blow head 1 308 and the blow head 2 9 are fixedly installed with a wind guide plate 10. The blow head 2 9 is used to extend the blowing channel, blow the air filtered by the filter 3091 toward the paperboard, reduce the probability of contact between the dusty air and the paperboard, and the wind guide plate 10 is provided to guide the wind blown out of the blow head 1 308 and the blow head 2 9 to ensure that the wind blows toward the paperboard;

[0028] The inner wall of the filter box 309 is fixedly installed with an inclined panel 6, the left end of the inclined panel 6 is higher than the right end, and the inclined panel 6 is located behind the filter screen 3091, and guides the filtered paper scraps and dust to the box door 3092, making it easier to take out the paper scraps and dust. A rotating pin 7 is fixedly installed on the top of the filter box 309, and a rotating plate 8 is rotatably sleeved on the outer wall of the rotating pin 7. The left side of the rotating plate 8 contacts the right side of the box door 3092, and the box door 3092 is limited by the rotating plate 8. When the box door 3092 needs to be opened, it is only necessary to rotate the rotating plate 8 to stagger with the box door 3092;

[0029] An avoidance groove 5 is provided on the outer wall of the guide plate 403, and the avoidance groove 5 corresponds to the dust collector head 305, the blowing head 308 and the blowing head 9. The avoidance groove 5 is provided to avoid the blowing head 308, the dust collector head 305 and the blowing head 9. When the guide plate 403 can guide the cardboard, it will not hinder the blowing head 308 and the blowing head 9 from blowing air to the cardboard, and the dust collector head 305 from sucking in paper scraps and dust.

[0030] Working principle: When in use, the paper scraps are placed at the right end of the belt conveyor 1 for conveying. After passing through the guiding plate 403, they are guided by the guiding plate 403. At the same time, the motor 302 and the dust suction pump 306 are started. The motor 302 drives the rotating shaft 303 to rotate, and then drives the cleaning brush 304 to rotate. The cleaning brush 304 brushes off the residual paper scraps on the cardboard. The dust suction pump 306 works to pump air into the filter box 309. Under the action of the air pressure difference, a negative pressure is formed at the dust suction head 305, and then the paper scraps and dust brushed off by the cleaning brush 304 are sucked into the dust suction head 305, and then sucked into the filter box 309. At the same time, the blowing air flow generated by the operation of the dust suction pump 306 enters the first blowing head 308 from the shunt pipe 307, and then blows from the first blowing head 308 to the cardboard, forming a stable air flow channel, thereby improving the removal effect of paper scraps and dust.

[0031] Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
