Efficient printing ink filtering device

Abstract

The invention discloses an efficient printing ink filtering device. The device comprises a conveying pump, a conveying pipe, a heating tank, a rotary joint, a feed pipe, a motor and a filtering tank,an outlet of the conveying pump is connected with the conveying pipe, the conveying pipe penetrates through the heating tank and is connected with the upper end of the rotary joint, the lower end of the rotary joint is connected with the feed pipe, a driven wheel and a bearing are arranged on the outer side of the feed pipe in a sleeving manner, and the driven wheel is connected with a drive wheel. The printing ink is heated, then the viscosity of the printing ink is reduced, the filtering efficiency is improved, different heating temperatures are set through a temperature control device to besuitable for different types of printing ink, the even heating is realized both in the water bath heating or the air heating, the printing ink is not deteriorated because of the excessively high temperature, the impurity is not easily adhered to a first filter screen along with the rotation of the filter screen under the action of gravity and falls into an impurity collection box, the impurity collection box can still be used continuously even if the impurity collection box is fully filled with the impurity, therefore, the service life is long, only the impurity in the impurity collection boxneeds to be cleared periodically, and the device is quite convenient to use.

Description

technical field [0001] The invention belongs to the field of printing, and in particular relates to a high-efficiency ink filter device. Background technique [0002] The viscosity and fluidity of the ink are both related to the temperature. When the temperature is higher, the viscosity of the ink is lower and the fluidity is better. When the temperature is lower, the viscosity of the ink is higher and the fluidity is worse. When the temperature is low, due to poor fluidity, the filtration rate of the ink filter device will decrease, which cannot meet the needs of workshop production. Secondly, after the existing ink filtering device is used for a period of time, impurities will gradually accumulate on the filter screen, resulting in a decrease in filtration rate, and the filter screen must be cleaned or replaced before it can be used normally. Filter replacement and cleaning work are relatively complicated and inconvenient to use. Contents of the invention [0003] Purp...
