Ink balancing device with interchangeable fill-in and continuous ink supply

Ink balancing device with filling and continuous ink supply interchange

The present invention relates to a printer ink supply device, and more particularly to an ink balancing device having a filling and continuous ink supply interchange.

In the conventional plotter, a larger ink supply device is usually required. As shown in FIG. 1 and FIG. 2, the general plotter 11 selects the ink bag type ink cartridge 13 and is sequentially inserted into the side-by-side sley 12 When the pattern is printed, the ink is supplied by the ink bag type ink cartridge 13; when the ink in the ink bag type ink cartridge 13 is used up, the new ink cartridge 13 is directly taken out; the empty ink cartridge after use can be filled and heavy. Reuse; usually discarded or recycled is no longer used.

In order to avoid the use of high-cost original ink cartridges, conventional ink cartridges used in conventional plotters are used as replacement ink cartridges made of plastic materials. The replacement ink cartridges have a plug-in structure that is inserted into the drawing machine and can be effectively used. Plugged into the sill of the plotter, an ink accommodating space is disposed inside the replacement ink cartridge, and the ink accommodating space can be made into different capacities according to requirements to supply different printing quantities; the substitute ink cartridge is located above There is an ink inlet port. When adding ink each time, it is usually necessary to add a proper amount of ink to the ink accommodating space of the replacement ink cartridge by using a funnel; each time the ink is added, the surrounding environment is always dripped and contaminated, and the cleaning is not easy. .

The main purpose of the creation is to insert a replacement ink cartridge into the drawing machine, and the external ink cartridge is externally connected with an ink balance guiding device, connected between the replacement ink cartridge and the large-capacity external ink bottle, and the ink balance guiding device is used. The structure of the valve body in the balanced connector of the two-terminal plug is different. When the two-end balanced joint is interchanged, one is to provide the filling of the ink inside the replacement ink cartridge, and the replaced replacement ink cartridge is provided by the balanced connector inserted above to provide the replacement ink cartridge interior. The pressure balancer of the ink accommodation space.

The secondary purpose of this creation is to replace the ink balance guiding device between the ink cartridge and the external ink bottle of the drawing machine.

The ink in the bottle is guided through the conduit to the replacement ink cartridge, and the balance connector inserted above the external ink bottle provides a pressure balance between the external ink bottle and the replacement ink cartridge.

A further object of the present invention is to provide an ink balance guiding device between the drawing machine replacing the ink cartridge and the external ink bottle, the ink balance guiding device is provided with two sets of balance joints between one conduit, one of which is micro pressure Balanced joints, one set is a constant pressure choke gas joint, and the second joint is used for interchangeable plugging between the substitute ink cartridge and the external ink bottle, and is used directly after the replacement ink cartridge is filled, or becomes an external ink after being replaced by the replacement ink cartridge. A continuous ink supply device for bottle supply.

The second purpose of the present invention is to provide an ink balance guiding device between the drawing machine replacing the ink cartridge and the external bottle. The micro pressure balance connector of the ink balance guiding device is inserted above the replacement ink cartridge, and the constant pressure balance connector is inserted. When the ink cartridge is filled over the external ink bottle, the ink balance guiding device is filled with the ink above the external ink bottle with a constant pressure balance joint, instead of the micro-pressure balance joint above the ink cartridge, instead of the ink inside the ink cartridge. When printing is consumed, a small amount of air is directly introduced from the micro pressure balance joint to balance the pressure inside the replacement cartridge.

A further object of the present invention is to provide an ink balance guiding device between the drawing machine replacing the ink cartridge and the external ink bottle. The constant pressure balance connector of the ink balance guiding device is inserted above the replacement ink cartridge, and the micro pressure balance connector is inserted. When the ink cartridge is placed above the external ink bottle, the ink balance guiding device is filled with the ink in the replacement ink cartridge, and is set with a constant pressure balance joint above the replacement ink cartridge, and the micro ink pressure balance connector is arranged above the external ink bottle to replace the ink inside the ink cartridge. When the printing is consumed, the ink in the external ink bottle is guided by the catheter into the replacement ink cartridge, and the inside of the external ink bottle is introduced with a small amount of air by the micro pressure balance joint to balance the pressure inside the external ink bottle.

A further object of the present invention is that the micro-pressure balance joint of the ink balance guiding device is provided with a hole on the body of the joint, the seat hole is provided with a spring, a valve stem and a valve seat, and the outer part is provided with a cover. The spring, which is disposed inside the main body hole, is arranged by a spring body having a slight pressure change, and the valve stem is held in close contact with the valve seat in the direction of the valve seat, and the micro pressure change occurs in the internal space of the micro pressure balance joint. Pulling the micro-pressure spring displacement, the valve stem and the valve seat are instantly opened, for a small amount of air to enter, and then return to the close state to provide a balance of the space pressure under the micro-pressure balance joint.

A further object of the present invention is that the constant pressure balance joint of the ink balance guiding device is provided with a hole on the body of the joint, and the seat hole is provided with a spring, a valve stem and a valve seat, and the outside is externally The cover is closed, and the spring disposed inside the body seat hole is provided by a coil spring which can be compressed by a finger, and the spring force can close the valve stem to the valve seat direction, and press the valve stem with pressure. The tight state between the seats.

The present invention relates to an ink balance guiding device having a filling and continuous ink supply interchange. As shown in FIGS. 1 to 3, the drawing machine 11 is located at a position of the sley 12 of the body, and a plurality of ink cartridges 13 are inserted, as shown in FIG. The cradle 12 of the plotter 11 is inserted with a plurality of replacement ink cartridges 14, and an ink balance guiding device is inserted above each of the replacement ink cartridges 14 to the upper portion of the external ink bottle 15, by the arrangement of the conduit 23, The ink 32 in the external ink bottle 15 is guided into the replacement ink cartridge 14, and the ink in the replacement ink cartridge 14 is easily replenished.
