An automatic cleaning device for ink pad printing machine

Abstract

The invention belongs to the field of printing ink cleaning devices, and particularly relates to an automatic cleaning device used for a printing ink transfer machine. The automatic cleaning device comprises an ink cartridge cabin, a printing plate and a cleaning unit. The printing plate is arranged under the ink cartridge cabin. The cleaning unit is located between the ink cartridge cabin and theprinting plate. The cleaning unit is used for cleaning the ink cartridge cabin and the printing plate, and comprises a motor, a supporting base, a rotating bar, a spray pipe and a blow-drying pipe. Afirst hole is formed in the center of the spray pipe, and the inner surface of the first hole is provided with spray holes penetrating through the outer surface of the spray pipe; a second hole is formed in the lower right corner of the first hole; the blow-drying pipe and the spray pipe are identical elements; and the spray pipe is used for cleaning the ink cartridge cabin and the printing plate, and the blow-drying pipe is used for blow-drying the ink cartridge cabin and the printing plate. By adopting the automatic cleaning device provided by the invention, a printing device can be automatically cleaned and blow-dried, and meanwhile, the ink cartridge cabin can be used for taking pigments in different colors in a hierarchical mode; and the quantities of printing patterns and charactersof a mold are large, the mold replacing frequency is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of ink machine cleaning devices, in particular to an automatic cleaning device for ink pad printing machines. Background technique [0002] Currently, printing presses generally use manually adjusted machines. For example, after pulping, the papermaking process is finished by circular net forming, pressing, pre-drying, surface trough sizing, starting point drying, soft matte, moisture scanning detection, and slitting, and the whole production is completed. In ordinary screen printing, the finished paper is fed, printed, and dried by hot air, then collected and stacked, and then put into the product warehouse. After 24 hours, it is flipped several times. The production process is long, the floor area is large, there are many machine operators, and the production cycle Long, time-consuming and labor-intensive; huge machinery and equipment, serious moisture loss and variability in paper; high product rejection rate and ...

Problems solved by technology

In ordinary screen printing, the finished paper is fed, printed, and dried by hot air, then collected and stacked, and put into the product warehouse. After 24 hours, it is flipped several times. The production process is long, the floor area is large, there are many machine operators, and the production cycle Long, time-consuming and labor-intensive; huge machinery and equipment, serious moisture loss and variability in paper; high product rejection rate and low degree of automation; when a batch of printed parts is printed or ink needs to be replaced, it is necessary to clean the scraping device , not only to remove all the remaining ink from the ink fountain and anilox roller, but also to clean the ink in the attached ink delivery conduit and ink discharge conduit

Ordinary cleaning equipment is complicated to operate, and the cleaning effect is not thorough, which will affect product quality

[0003] There are also some technical solutions for ink machine cleaning devices in the prior art. For example, a Chinese patent with application number 201420314515.4 discloses a printing machine with an ink unit cleaning device, including a paper loading shaft, and a paper loading shaft. The plate cylinder on the left side of the shaft, the impression cylinder set on the left side of the plate cylinder, the printing roller close to the impression cylinder, the anilox roller connected to the printing roller, and the scraping ink close to the anilox roller Knife bracket, and the ink cleaning device connected with the doctor blade bracket, and the cutting and dismantling device connected with the impression cylinder; the ink cleaning device includes a set of pumps and valve units, and ink delivery conduits, and ink conduits , and the solvent conduit, and the solvent storage tank, and the ink storage tank, and the dirt tank, and the filter box; although this technical scheme can clean the ink machine, the technical scheme structure is relatively complicated, and at the same time, it cannot be used for multiple colors.
