Description
Technical Field
The utility model belongs to the technical field of metal sheet surface printing equipment technique and specifically relates to a belt cleaning device of metal sheet printing equipment transfer rubber roll.
Background
The metal printing decorative plate is an integrated heat-insulating plate, and has a new installation mode capable of replacing traditional wood grains and stone grains, and is applicable to public fields of building interior, exterior wall decoration, airport, subway, market and the like, and generally comprises a metal plate base layer and a printing composite layer arranged on the metal plate base layer, according to the requirements of printing, the metal strip material is repeatedly processed on printing equipment by oiling, drying, re-oiling and re-drying to form the desired pattern color, because the whole printing production line is longer and is continuously produced, the related process factors are complex and the parameters are easily uncontrollable to change, the color difference of the front and rear printing patterns on the metal plate is easy to exist, the color difference of the printing at the close position can not be seen, but the color difference of the patterns at the position far away from each other on the whole roll of strip material can exist, obvious colour difference can exist at the head and the tail ends, when the follow-up processing is carried out, the whole roll of printed board is cut into specification block materials after being compounded, the block material construction with the colour difference influences the beauty when being spliced together, the due function of the decorative board is lost, personnel with abundant construction experience can select to use, or the colour difference board is put to a position far away from the sight, even if so, the construction quality and the efficiency are influenced, and for a production enterprise pursuing high quality, the problem of solving the colour difference of the printed board can improve the popularity of products and improve the user experience.
The main process of printing is that the printing ink is coated on the engraved roller, the transfer rubber roller contacted with the engraved roller is used for transfer printing the printing ink on the metal plate, and the part of the transfer rubber roller after transfer printing needs to be cleaned so as to receive the printing ink transferred from the engraved roller again, so that the printing device is also provided with a cleaning device, the cleaning device mainly comprises a cleaning roller contacted with the transfer rubber roller and a liquid containing disc containing cleaning liquid, and the cleaning roller is half immersed in the liquid containing disc.
The existing cleaning device is shown in figures 1 and 2, a cleaning liquid outlet is arranged above a contact position of a cleaning roller and a transfer rubber roller, the falling cleaning liquid washes the contact position and flows into a liquid containing disc, the cleaning liquid in the liquid containing disc is pumped to the liquid outlet, and a liquid taking port of a pump is positioned at the upper part of the liquid containing disc, so that ink molecules deposited at the bottom of the liquid containing disc are not extracted, wherein the liquid containing disc is flat-bottom, which is an ideal cleaning mode which is easy to think, but the cleanliness of the cleaning liquid is not ensured in the whole course, so that the actually produced printing plate still has color difference.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the defects in the prior art are overcome, and the cleaning device is provided, so that the printing color difference of the metal printing plate is reduced.
The utility model provides a technical scheme that its technical problem adopted is: the method comprises the following steps of analyzing various reasons of color difference, finding a condition which is easy to ignore, namely a cleaning device, wherein the cleaning roller is immersed in the liquid containing disc, residual liquid of liquid in the liquid containing disc is remained on the cleaning roller, the residual liquid can be brought into next transfer printing, if the component color of cleaning liquid in the liquid containing disc changes, the color difference of a printing plate can be inevitably caused, and the fact that the cleanness degree and the uniformity degree of the cleaning liquid in the liquid containing disc are not changed is an important means, on the basis of which:
a cleaning device for a transfer rubber roll of metal plate printing equipment is provided with a liquid containing disc containing cleaning liquid and a cleaning roll which is partially immersed in the liquid containing disc and used for cleaning the transferred rubber roll after transfer printing, wherein an overflow outlet is arranged in the liquid containing disc, the overflow outlet is connected to a liquid storage barrel, the liquid containing disc is provided with a slope-shaped bottom and a bottommost sinking groove which are convenient for collecting and discharging settled ink molecules in the cleaning liquid, the length direction of the sinking groove is consistent with the length direction of the liquid containing disc and is the same as the axial direction of the cleaning roll, a plurality of discharge ports which are arranged along the length direction of the sinking groove and used for uniformly discharging the settled ink molecules in the sinking groove are arranged at the sinking groove, and each discharge port is provided with a control valve;
a plurality of liquid supplementing ports which are arranged along the length direction and are used for supplementing cleaning liquid uniformly are arranged above the liquid containing disc, the liquid supplementing ports are connected to the liquid storage barrel through pipes, and a pump is arranged on a pipeline between each liquid supplementing port and the corresponding liquid storage barrel.
Specifically, in order to better maintain the uniformity of the cleaning liquid in the liquid containing disc, the discharge ports are arranged at equal intervals.
In particular, the liquid supplementing openings are arranged at equal intervals for better maintaining the uniformity of the cleaning liquid in the liquid containing tray.
The utility model has the advantages that: the cleaning device changes the original cleaning method, only maintains the cleanness and uniformity of the cleaning liquid in the liquid containing disc unchanged, and avoids the problem that the cleaning roller brings the cleaning liquid with changed color to the transfer rubber roller to cause printing color difference.
