Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 to 3, a dust removing device of a printing press according to the present utility model includes a frame 1, six transfer rollers 2 are rotatably disposed on a sidewall of the frame 1, the transfer rollers 2 are driven by a motor, and printing paper 8 can be transported and printed by the transfer rollers 2. The frame 1 is fixedly provided with an air nozzle 3, the air nozzle 3 adopts a long-ruler type high-pressure nozzle, and the length of the air nozzle 3 is the same as the width of printing paper 8. The air nozzle 3 is positioned above the printing paper 8 and is inclined downwards towards the paper feeding direction of the printing paper 8, and dust on the upper surface of the printing paper 8 can be blown off towards the paper feeding direction by opening the air nozzle 3.

A dust hood 4 is also fixedly arranged on the side wall of the frame 1, and the dust hood 4 is positioned in the direction of the printing paper 8. The dust collection cover 4 is a cuboid box body with one side open, and the opening of the dust collection cover 4 faces the direction of the printing paper 8, so that dust on the surface of the printing paper 8 blows off towards the inside of the dust collection cover 4. A replacement assembly is arranged in the dust hood 4. The changing assembly comprises a unreeling shaft 52, a reeling shaft 51 and a guiding roller 6 arranged on the side wall of the frame 1. The unreeling shaft 52 and the reeling shaft 51 are respectively and rotatably connected above and below the dust hood 4, and the side walls of the frame 1 are respectively and fixedly provided with a driving motor 9. The two drive motors 9 are fixedly connected with the unwinding shaft 52 and the winding shaft 51 coaxially respectively. The guide rollers 6 are provided with six groups, and each group of guide rollers 6 are positioned at the same horizontal height and symmetrically arranged. Wherein two groups of guide rollers 6 are symmetrically arranged on the side wall of the frame 1 respectively, and the other four groups of guide rollers 6 are symmetrically arranged on the inner side wall of the dust hood 4 respectively. The dust-binding paper 7 is transported from the unreel shaft 52 to the take-up shaft 51 along the inner side wall profile of the dust hood 4 by the guide roller 6. The adhesive surface of the dust-binding paper 7 faces to the opening of the dust hood 4.

During normal use, the air nozzle 3 blows dust on the upper surface of the printing paper 8 into the dust collection cover 4 and is adsorbed by the dust binding paper 7 in the dust collection cover 4, so that the effect of preventing the blown dust from flying in the air and affecting the working environment is achieved. After the dust-binding paper 7 in the dust hood 4 is used for a while, the adsorption effect on dust is greatly reduced, so that it needs to be replaced. At this time, only the driving motor 9 needs to be turned on, and the driving motor 9 drives the unwinding shaft 52 and the winding shaft 51 to rotate, so that the new dust-binding paper 7 enters the dust hood 4, and the old dust-binding paper 7 is recovered on the winding shaft 51. The same group of guide rollers 6 are provided with a gap, so that the contact area between the dust-binding paper 7 and the guide rollers 6 is reduced, and the adsorption area is increased. Meanwhile, the side wall of the dust hood 4 corresponding to the opening of the dust hood is provided with a cleaning opening, the cleaning opening is hinged with a cover plate 41, and the guide roller 6 and the inner wall of the dust hood 4 can be cleaned regularly by opening the cover plate 41.
