Description

Paper vacuum ink container

The invention relates to a paper vacuum ink container, more specifically to a vacuum packaging storage ink, which can be combined with a pneumatic automatic ink supply device, an electric ink supply device, a lever manual ink supply device and a screw propulsion ink supply device. A paper vacuum ink container for use.

Background technique:

In the printing industry, the ink cylinder used in modern printing presses is a tubular cylinder. One end of the cylinder is equipped with a piston, and the other end of the cylinder has an ink outlet. The ink outlet is sealed by two plastic covers. The two hard-surfaced plastic covers are sealed together, and the outside air enters the cylinder through the gap. The piston structure defect cannot discharge the air in the cylinder, which causes air to remain when the ink is filled. The ink is inhaled during storage and transportation, which causes the ink to oxidize and dry and crust, which directly affects the quality of the ink and causes the ink to flow out.

For example, Chinese Patent Nos. 200710099625.8 and 200610000728.X respectively disclose a vacuum ink container. When the container is packaged with a piston (rear cover), the air inlet of the vent hole is located at the side of the piston, and the axis of the vent hole is perpendicular to the axis of the cylinder. Intersecting, exhausting through the exhaust hole on the side of the piston, the air in the cylinder cannot be completely discharged, and the air remaining in the cylinder causes the ink to crust, which directly affects the quality of the ink. The front end of the container is sealed by two plastic caps, and the inside of the container is easy to inhale air, which causes the ink to dry and crust, which affects the quality of the ink. .

The plastic cylinder will expand and contract, causing the piston to fit loosely or tightly. If the fit is too loose, the piston will easily loosen and the ink will easily enter the air. If the fit is too tight, the ink supply pressure will increase, causing the piston. Pushing is not in place, affecting ink flow. International PCT/CN 20.08/073722 paper vacuum ink container, the front end cover of the container is a tinplate easy-open cover, the ring pre-break line on the cover is of poor strength, easy to break, easy to break, the easy-open cover end cover is easy to change, and the pressure resistance is poor. , Easy pull ring is easy to break. The ink outlet is a large opening with full-caliber ink, which is easy to soil the environment and cannot control the ink flow. When the front end surface of the piston is flat, there are too many vent holes to be provided. The surface of the vent hole is too wide to completely discharge the air at the piston end of the cylinder. The air remaining will cause the ink to dry and crust, which directly affects the ink quality.

U.S. Patent No. 6,309,059, B1, and U.S. Patent No. 7,128,244, the disclosure of each of each of each of each of each of each of

1. The ink tank cover and the safety cover rely on the outer wall of the round head of the plastic main cover to be sealed with the inner wall of the top of the plastic outer cover. The two hard plastic surfaces are interlocked, and the air cannot pass through the gap between the ink tanks. After the ink is heated and cooled in the tank, the volume of the ink will shrink and shrink, and a negative pressure will be generated in the tank. In addition, the external air is sucked into the tank, which causes the ink to oxidize and dry the skin, which directly affects the ink quality. Can cause ink to flow out.

2. The inside of the main cover of the can lid is a long and small circular space. When the ink is poured in, the air cannot be quickly discharged, and it remains in the main cover, which causes the ink to oxidize and dry the skin, directly affecting the ink quality and blocking the ink outflow. . .

3. The above can lid can only be used on plastic cylinders.

4. The above can lid can only be used in conjunction with the pneumatic automatic feeding device, which has the following problems:

a. Because the cover of the main cover is interlocked and sealed, the air pressure required to open the ink nozzle of the can lid is high. The thrust of the piston is large and can only be used with a pneumatic automatic ink supply device on a new standard printing machine with normal air pressure. It is not suitable for all printing presses.

b. The air pressure is high, the thrust of the piston is large, and the thrust is too large, which may cause the piston to rotate inside the cylinder, resulting in the inability to supply ink.

c. Since the can lid is supplied with ink through the ink nozzle, the thrust required for the ink to open the ink nozzle is large, and the thrust is too large to adapt to the simple and light, the price of the electric ink supply device, the lever manual ink supply device and the screw advance ink supply device.
