Problems solved by technology

[0002] At present, when printing text or patterns on paper, printing machines are usually used for inkjet printing. However, on the one hand, due to the large amount of dust generated in the production workshop, dust will fall during the transportation of paper before entering the printing machine. On the surface of the paper, even solid attachments are formed. On the other hand, the surface of the paper itself will adhere to a lot of fine paper dust, or debris generated when the paper is cut. It will be mixed into the ink, affect the printing quality, cause the printing is not clear, and may block the equipment in severe cases, so it is necessary to clean the surface of the paper entering the printing machine

Embodiment Construction

[0016] The present invention will be further described through specific embodiments below in conjunction with the accompanying drawings.

[0017] As shown in the figure, a paper surface cleaning device for a printing machine includes a cleaning box 2 connected to the entrance of the printing machine 1, and a conveying path for paper 10 is provided at the bottom of the cleaning box 2, and the paper 10 is placed between the rollers 9. Under transportation, enter and pass through the lower part of the cleaning box 2, and enter the printing machine 1 for inkjet printing. The lower edge of the cleaning box 2 is smoothly arranged, and a support plate 6 with a cavity inside is provided on the inside of the cleaning box 2, and one end of the support plate 6 is fixed. On the top of the cleaning box 2, the other end is inclined away from the entrance of the printing machine 1, and the cleaning box 2 is divided into a dust removal area 201 at the front and a cleaning area 202 at the rear....

Abstract

A closed type dust removal device for a printing press comprises a cleaning box communicated with an inlet of the printing press, and a supporting plate inclining in the direction backing on to the printing press is arranged on the top of the inner side of the cleaning box and divides the cleaning box into a dust removing area and a cleaning area. A hairbrush and a dust exhaust mechanism are arranged in the dust removing area, and an air blowing mechanism is arranged in the cleaning area. The air blowing mechanism comprises a dust blowing pipe and an air curtain pipe. The dust blowing pipe is arranged in a cavity of the supporting plate, the air blowing direction of the dust blowing pipe is oblique, air blown out from the dust blowing pipe can raise dust on paper and attachments brushed up by the hairbrush, and the dust and the attachments can be exhausted by the dust exhaust mechanism. The air curtain pipe comprises a vertical segment and a horizontal segment, the vertical segment is arranged on one side of the inlet of the printing press, the air outlet direction of the vertical segment faces the other side of the inlet, and then an air curtain closing the inlet is formed; the horizontal segment is arranged on one side of the cleaning box, the air outlet direction of the horizontal segment faces the other side of the cleaning box, and then an air curtain closing the paper face is formed. According to the closed type dust removal device for the printing press, the dust on the paper is effectively cleared through cooperation of the hairbrush, the air blowing mechanism and the dust exhaust mechanism, and printing quality is guaranteed.
