Description

Runner control system

This case is about a control system, especially a flow control system.

In the cleaning system of the inkjet printer, the ink pumping system is very important for the cleaning of the nozzle. The ink pumping system mainly pumps ink to the waste ink area by the ink absorption pad running through the ink pump. The settings of the ink pump speed and operating parameters often affect the overall cleaning performance. Generally speaking, inkjet printers usually have more than two nozzles and their respective matching flow channels. When the ink pump performs ink extraction, a single ink pump corresponds to multiple nozzles for ink absorption and cleaning.

In this way, although all nozzles can be cleaned, it is also accompanied by the following shortcomings: First, when only the nozzle hole of a single nozzle needs to be cleaned, all normal nozzles must be cleaned together due to mechanical design factors. A nozzle and its flow path must output ink for cleaning action, resulting in excessive ink consumption; in addition, cleaning all nozzles at the same time may also cause the normal nozzle or its flow path to be blocked, and even cause additional damage to the nozzle, resulting in a successful cleaning rate reduce. Therefore, the conventional technology has the problem of low cleaning efficiency for the cleaning of the nozzle.

Therefore, how to develop a flow channel control system that can open and close the two flow channels separately or at the same time through phase control is a problem that remains to be solved.

The main purpose of this case is to provide a flow channel control system to solve and improve the aforementioned problems and shortcomings of the prior art.

Another objective of the present case is to provide a flow channel control system, which can achieve the control of the first flow channel and the second flow channel by operating the phase choke device between the first phase, the second phase, the third phase and the fourth phase. Separate or simultaneous opening and closing control can reduce fluid waste according to demand.

Another purpose of this case is to provide a flow channel control system. When the flow channel control system is applied to the cleaning system of the inkjet printer, the control of the flow channel resistance is achieved through the control of the motor or solenoid valve, which can effectively target the nozzles that need to be cleaned. For cleaning, the flow channel connected to the normal nozzle is closed correspondingly, which can effectively reduce the waste of ink and save the cost of printing. At the same time, because unnecessary cleaning is not performed, it can effectively improve the cleaning efficiency, reduce the time consumed for cleaning, and improve Printing efficiency and productivity.

To achieve the above objective, a preferred implementation aspect of the present application is to provide a flow channel control system, which is suitable for controlling a first flow channel and a second flow channel, including: a housing, wherein the first flow channel and the second flow channel The flow channel passes through the housing; a phase choke device is arranged in the housing and is adjacent to the first flow channel and the second flow channel; and a driving device is connected to the phase choke device; The phase choke device is driven by the driving device to operate between a first phase, a second phase, a third phase, and a fourth phase. When the phase choke device operates in the first phase, the The first flow channel is blocked by the phase blocking device and the second flow channel remains unblocked. When the phase blocking device operates in the second phase, the second flow channel is blocked by the phase blocking device and the The first flow channel remains unblocked. When the phase choke device is operating in the third phase, the first flow path and the second flow path are simultaneously compressed and blocked by the phase choke device, and when the phase choke device is operating in the In the fourth phase, the first flow channel and the second flow channel remain unblocked.

In short, the arrangement of the first electromagnetic driver 331 and the second electromagnetic driver 332 on the upper cover 311 is diagonally arranged, but not limited to this, it can effectively reduce the overall volume of the product.

To sum up, this project provides a flow channel control system. By operating the phase choke device between the first phase, the second phase, the third phase, and the fourth phase, the first flow channel and the second flow channel Separate or simultaneous opening and closing control can reduce fluid waste according to demand. Furthermore, when the flow channel control system is applied to the cleaning system of the inkjet printer, the flow resistance of the flow channel can be controlled through the control of the motor or solenoid valve, which can effectively clean the nozzles that need to be cleaned, and the flow channels connected to the normal nozzles The corresponding closing can effectively reduce the waste of ink and save the cost of printing.
