Problems solved by technology

[0002] At present, the printing machine is mainly used for printing text and patterns on paper. During the use of the printing machine, dust often falls on the paper when the paper enters the printing machine, or the paper is produced. After printing, it is easy to produce paper dust. These dust or paper dust will be mixed into the ink in the printing machine during the printing process, affecting the printing quality, often causing unclear printing, and may even block the printing equipment.

Embodiment 1

[0024] The example is basically as attached figure 1 Shown: a dust blowing device for a printing machine, comprising a transfer table 2 and a printing machine body 3, and a bracket 1 is welded and fixed to the bottom ends of the transfer table 2 and the printing machine body 3.

[0025] The printing machine body 3 is provided with a feeding port (not shown in the figure), the feeding port is located on the left side of the printing machine body 3 , and the feeding port is used for feeding paper into the printing machine body 3 for printing. The printer body 3 in this embodiment is in the prior art, and the working principle is the same as that of the printer in the prior art, which will not be repeated here.

[0026] The transfer table 2 communicates with the feeding port of the printer body 3 , and the transfer table 2 is used to transfer paper from the feeding port into the printer body 3 . A sliding plate 5 is arranged above the transfer table 2, and the sliding plate 5 is...

Embodiment 2

[0036] like figure 2 As shown, a dust blowing device for a printing press is different from the first embodiment in that the top end of the support frame 4 is fixedly connected with an air cylinder 10 by bolts, and the output shaft of the air cylinder 10 and the connecting plate 9 are fixedly connected by bolts.

[0037] In this embodiment, the vertical movement of the connecting plate 9 is automatically controlled by driving the air cylinder 10, thereby controlling the vertical movement of the driving plate 6. This solution does not require manual pressing of the connecting plate 9, which saves labor and labor costs.

Abstract

The invention relates to the field of printing equipment, and discloses a dust blowing device for a printing machine, which comprises a transfer table and a printing machine body. The mouths communicate with each other, a sliding plate is arranged above the conveying platform, the sliding plate is fixedly connected with the main body of the printing machine, and a sliding slot is opened in the longitudinal direction of the sliding plate. A pressing rod is connected, and the bottom end of the pressing rod protrudes from the bottom end of the sliding plate. The sliding plate also includes a driving unit that drives the moving plate to reciprocate vertically. The top of the printing machine body is provided with a vacuum cleaner. The vacuum cleaner A dust suction pipe is communicated with the top, and the bottom end of the dust suction pipe is arranged facing the transfer table. The invention can remove the dust or paper scraps on the paper before printing, thereby improving the printing quality.

Description

technical field [0001] The invention relates to the field of printing equipment, in particular to a dust blowing device for a printing machine. Background technique [0002] At present, the printing press is mainly used to print text and patterns on the paper. During the use of the printing press, it often occurs that when the paper enters the printing press, dust will fall on the paper, or the paper is produced during production. It is easy to produce paper scraps after the printing process. These dusts or paper scraps will be mixed into the ink in the printing machine during the printing process, which will affect the printing quality, often cause the printing to be unclear, and may even block the printing equipment. SUMMARY OF THE INVENTION [0003] The present invention intends to provide a dust blowing device for a printing press to remove dust or paper scraps on paper before printing, thereby improving the printing quality. [0004] In order to achieve the above pur...
