Description

Automatic filling production line for printing ink cylinder

Technical Field

The utility model relates to an ink cylinder filling field specifically relates to an automatic filling production line of ink cylinder.

Background

The ink cartridge is a special consumable material for the digital integrated rapid printer, and because the digital integrated rapid printer has the advantages of economy, environmental protection, high printing speed, good definition and the like in printing, in recent years, the consumption is more and more large, and particularly, the consumption is larger in schools, enterprises and public institutions and the like with larger printing quantity, so that the consumption of the ink cartridge which is one of the consumable materials is also more and more large. The structure of the ink cartridge 100 for the digital integrated stenograph is shown in fig. 1, and the ink cartridge comprises an ink cartridge body 101, a card mouth 102, an ink cover 103, a piston 104, a bottom cover 105 and the like. The main body part is a cylindrical ink cartridge body with the wall thickness of about 2 mm and the diameter of about 80 mm; at the upper end of the barrel is an ink nozzle 106. After the ink tank is filled with ink, a card nozzle is required to be arranged in the ink nozzle, and the card nozzle is an ink injection interface which is connected with a machine table when the ink cylinder is arranged on the digital integrated stenograph. Normally fill the ink cylinder that fills up with printing ink, need cover the printing ink lid to prevent that printing ink from overflowing, just unscrew the printing ink lid when need install on the integrative stenograph of digital. The digital integrated stenograph is characterized in that a piston is arranged in an ink cylinder body, and when the digital integrated stenograph is used for printing, the piston in the ink cylinder is pushed by an ejector rod of a machine table to enable ink to be injected into a printing roller of the machine table for printing. The bottom of the ink cylinder body is provided with a bottom cover with a hole, so that the piston is prevented from being separated from the cylinder body.

At present, the domestic printing ink filling machine aiming at the printing ink cylinder is a single machine filling machine which generally adopts an inverted filling process, only one printing ink cylinder can be filled at each time, air is exhausted before the printing ink cylinder is filled, other procedures such as installing and clamping a nozzle after filling, covering an ink cover and the like can be completed only through manual operation, the production efficiency is low, the labor intensity of workers is high, and particularly the installing and clamping nozzle and the covering of the ink cover enable the hands of the workers to frequently screw out blood bubbles. The inverted filling process has the advantages that the inverted filling process is simple in structure, the ink nozzle of the ink cylinder which is manually exhausted is downwards buckled on the filling nozzle of the filling machine during filling, and the filling machine pushes the piston to slowly move upwards until the ink cylinder is filled with ink; the inverted filling process has the defects that the inverted filling process cannot be used for an automatic filling production line, and mainly because the ink nozzle faces downwards, the ink can is easily poured out after leaving the filling nozzle of a filling machine, and the subsequent procedures of installing the clamping nozzle, covering the ink cover and the like are difficult to realize automation, so other procedures only need to adopt manual operation, and the production efficiency is difficult to improve.
