Description

Automatic cleaning tank for gravure roller of printing machine

Technical Field

The utility model belongs to the technical field of large-scale gravure press corollary equipment and specifically relates to an automatic cleaning tank in cleaning machine that gravure roll of gravure press used after printing.

Background

At present, a plate roller used by an intaglio printing machine can be stored in a warehouse after being cleaned after pattern printing is finished. The existing method for cleaning the printing roller is to start the printing machine again under the non-printing condition after the printing of the printing machine is finished, so that the printing roller runs on the printing machine at a slow speed, and then manually brush and spray the surface of the printing roller by using clean water, a scrubbing brush and a chemical solvent in a manual mode. Because the mesh pit of the printing roller is very small, a long time is needed for cleaning the printing roller, and the effective printing working time of a printing machine is needed to be occupied when the printing roller is cleaned; in addition, water and cleaning liquid for manually cleaning the printing roller can be directly discharged after being used once, so that great resource waste is caused, the production cost is increased, and the enterprise burden is increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the not enough of above-mentioned background art, provide a printing machine gravure roller automatic cleaning tank, this washing tank can carry out self-cleaning to version roller surface to can not occupy the normal printing operating time of printing machine, with the waste of avoiding lithography apparatus's air-loss, improve the washing speed and the cleaning quality of version roller, reduction in production cost.

The utility model provides a technical scheme is:

the utility model provides a printing machine gravure roller automatic cleaning groove which characterized in that: comprises a box body with an open upper part, an upper washing pipe and a lower washing pipe which extend into the box body, and a brush roller which can be positioned in the box body in a rotating way around the axis of the brush roller; an accommodating chamber for accommodating the printing roller is arranged in the box body; the bottom of the box body is provided with a discharge port; the outer surfaces of the upper washing pipe and the lower washing pipe are provided with a plurality of spray holes aligned with the containing cavity so as to spray washing liquid to the printing roller; and the outer surface of the brush roller is provided with a flexible object so as to be in close contact with the outer surface of the plate roller and scrub the plate roller.

The axial directions of the upper washing pipe, the lower washing pipe and the brush roller are parallel to each other and are horizontally arranged.

The lengths of the upper washing pipe, the lower washing pipe and the brush roller are not less than the length of the plate roller.

The rotating direction of the brush roller is opposite to the rotating direction of the plate roller in the accommodating chamber.

The working principle of the utility model is as follows:

when the device works, an external transfer mechanism (such as a self-rotating mechanical arm) is adopted to automatically grab a printing roller to be cleaned, the printing roller is conveyed to the accommodating cavity of the box body, the upper washing pipe and the lower washing pipe wash the surface of the printing roller at high pressure, the printing roller rotates around the axis of the printing roller under the driving of the transfer mechanism, so that the washing water is uniformly sprayed onto the surface of the printing roller, then the brush roller rotates, the surface of the printing roller is scrubbed through a flexible object, and stains and impurities on the surface of the printing roller are further cleaned. After high-pressure washing and scrubbing, a large amount of printing ink sundries left on the surface of the printing roller can be cleaned to about 95-100%, and then the printing roller is sent out of the box body by the transfer mechanism to complete the cleaning of the printing roller; the waste water generated when the plate roller is cleaned in the cleaning tank is discharged from the outlet.

The utility model has the advantages that:

the utility model discloses a wash on the pipe and wash the pipe down and wash version roller surface to rotate through the brush roller, utilize the flexible thing of brush roller surface to scrub version roller, replaced the manual work among the traditional cleaning means and washed and scrub, realized the self-cleaning of version roller, practiced thrift the manpower, improved the washing speed and the cleaning quality of version roller greatly. In addition, the printing roller is conveyed into the box body by the transfer mechanism to be cleaned, so that the normal printing working time of the printing machine is not occupied, the waste of the printing machine due to empty consumption is avoided, and the production cost is reduced.

Detailed Description

The following further description is made with reference to the embodiments shown in the drawings.

The automatic washing tank for the gravure roller of the printing machine comprises a tank body 1, an upper washing pipe 4, a lower washing pipe 2 and a brush roller 3. The upper part of the box body is open; the interior of the box body is provided with an accommodating chamber used for accommodating a printing roller to be cleaned; during operation, a plate roller 6 to be cleaned is conveyed into the accommodating cavity of the box body by an external transfer mechanism 5 (such as a self-rotating mechanical arm in the prior art), and the plate roller can move and rotate under the driving of the transfer mechanism. The bottom of the box body is provided with a discharge port 7 for discharging sewage generated when the printing roller is cleaned.

The upper washing pipe and the lower washing pipe extend into the box body, and a plurality of spray holes aligned with the accommodating cavity are formed in the outer surfaces of the upper washing pipe and the lower washing pipe so as to spray washing liquid to the printing roller and perform high-pressure washing on the printing roller; preferably, the orifices are arranged uniformly along the axial direction of the upper and lower wash pipes.

The brush roller can be rotationally positioned in the box body around the axis of the brush roller, and the outer surface of the brush roller is provided with a flexible object 8 which can be tightly contacted with the outer surface of the plate roller. When the flexible plate roller brushing device works, the flexible object is utilized to brush the plate roller under the rotation of the brush roller. Preferably, the rotation direction of the brush roller is opposite to the rotation direction of the printing roller in the accommodating chamber, so that the brushing effect of the printing roller is improved.

Preferably, the upper washing pipe, the lower washing pipe, and the brush roller are arranged in parallel and horizontally in the axial direction. Preferably, the lengths of the upper washing pipe, the lower washing pipe and the brush roller are not less than the length of the plate roller.

Finally, it should be noted that the above-mentioned embodiments illustrate only specific embodiments of the invention. Obviously, the present invention is not limited to the above embodiments, and many variations are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the invention should be considered as within the scope of the invention.
