Description

Technical Field

[0001] The utility model relates to the technical field of reducing dust, in particular to a device for reducing dust of a printing machine. Background Art

[0002] During the printing process of the printing press, a large amount of paper dust contained in the paper will fly everywhere in the dry room, which has different degrees of impact on the quality of the printed matter and the health of the staff. It is necessary to collect and treat these dusts specially; the existing dust collectors have certain disadvantages when used. First, after the dust is inhaled, it cannot be adsorbed to the maximum extent, and it cannot effectively prevent the dust from flying around. Secondly, when the dust collector is used for a long time, it is easy to cause blockage, and it is even more impossible to know the dust collection situation inside the dust collector in real time, so it cannot be processed in time, which brings certain impacts during use.

[0003] At present, publication number CN209738510U discloses a dust-absorbing printing machine. By setting an exhaust fan, the dust will be sucked into the air inlet pipe and then fall into the dust storage chamber through the air outlet pipe. The process collects the dust, reduces the possibility of dust flowing in the air, provides a safer working environment for the operators, and reduces the situation where the dust affects the health of the operators. The collected dust will fall into the dust storage chamber, and the dust in the dust storage chamber can be easily cleaned through the cleaning door, which helps to speed up the cleaning efficiency. By setting a dust hood, the dust hood can completely cover The top of the base can absorb the fallen dust into the air inlet pipe to a large extent, which helps to improve the dust collection effect. A partition net is set on the dust hood to reduce the problem of paper being sucked into the air inlet pipe and causing blockage of the air inlet pipe, which helps to increase the service life of the device. By setting a dust storage bag, the dust storage bag can collect dust, which is convenient for cleaning the dust accumulated in the dust storage cavity, and helps to improve the cleaning efficiency. By setting fasteners and fastening rings, the dust storage bag is firmly connected to the air outlet pipe to reduce the possibility of the dust storage bag falling. By setting a handle, the handle can easily open the cleaning door for easy operation.

[0004] In order to solve the problem of cleaning and collecting dust in the printing machine in the above technical solution, the existing technology adopts a method of providing fasteners and fastening rings to firmly connect the dust bag to the outlet pipe to reduce the falling of the dust bag. However, there is still a problem of insufficient filtering effect on the dust, which leads to the problem of insufficient effect of degrading and cleaning the dust. Utility Model Content
