High-stability printing ink conveying equipment

Abstract

According to the printing ink conveying equipment with the high stability, in the working process of the printing ink conveying equipment with the high stability, the diaphragm pump air source supplies air to the printing ink diaphragm pump; the diaphragm pump air source pumps ink in the ink barrel into the ink output pipe through the ink input pipe and the ink pumping pipe and conveys the ink to an external ink box through the ink output pipe. And when a preset amount of ink is added into the external ink box, the electromagnetic valve is closed. When the electromagnetic valve is closed, the reciprocating speed of the diaphragm pieces in the two diaphragm transmission cavities of the ink diaphragm pump is gradually reduced, and when the Hall sensor detects that the reciprocating speed of the pressing plate on the diaphragm pieces is lower than a preset value, the reciprocating speed of the pressing plate is lower than the preset value. And the control mechanism controls the diaphragm pump air source to stop working, so that the ink diaphragm pump is closed. The damage to the printing ink diaphragm pump caused by overlarge air pressure in the two diaphragm transmission cavities of the printing ink diaphragm pump is avoided, so that the stability of printing ink conveying operation is improved.

Description

Technical Field

[0001] This utility model relates to the field of ink delivery, and in particular to ink delivery equipment with high stability. Background Technology

[0002] Printing ink is an essential material used in printing, transferring patterns and text onto a substrate through printing or inkjet printing. It comprises main and auxiliary components, which are uniformly mixed and repeatedly rolled to form a viscous, colloidal fluid. It consists of binders, pigments, fillers, additives, and solvents. It is used in various printing applications, including books, packaging, architectural decoration, and electronic circuit boards. With increasing societal demand, the variety and production volume of printing inks have expanded accordingly. The development of printing ink is inextricably linked to the development of printing plates; a mismatch between the two leads to unclear printing, ink film peeling, and compromised print quality. During the printing process, a quantitative replenishment of ink is necessary in the ink container.

[0003] However, in traditional ink delivery equipment, such as the technical solution protected by the patent application number CN201520020076.0 entitled "Ink Delivery System", when the output pipe of the ink diaphragm pump is closed but the air source of the diaphragm pump is not closed, the pressure inside the ink diaphragm pump is too high, which will affect the working stability of the diaphragm pump and thus affect the working stability of the ink delivery equipment. Utility Model Content

[0004] Therefore, it is necessary to provide a highly stable ink delivery device to address the technical problem that excessive pressure inside the ink diaphragm pump after the output pipe of the traditional ink delivery equipment is closed, which affects the working stability of the diaphragm pump and thus the working stability of the ink delivery equipment.

[0005] A highly stable ink delivery device includes: an ink diaphragm pump, a diaphragm pump air source, an ink input pipe, an ink output pipe, an ink extraction pipe, an ink tank, two Hall effect sensors, and a control mechanism.

[0006] The output end of the diaphragm pump air source is connected to the air inlet end of the ink diaphragm pump; the input end of the ink diaphragm pump is connected to the ink output pipe through the ink input pipe; the ink output pipe is inserted into the ink container; the output end of the ink diaphragm pump is connected to the ink output pipe; a solenoid valve is installed on the ink output pipe.

[0007] Each of the Hall sensors is disposed in a diaphragm drive chamber of the ink diaphragm pump and connected to the housing of the ink diaphragm pump; the Hall sensor is used to detect the position of the pressure plate on the diaphragm sheet in the drive chamber of the ink diaphragm pump;

[0008] The diaphragm pump air source, the solenoid valve, and the two Hall sensors are all electrically connected to the control mechanism.

[0009] In one embodiment, an ink filter is provided on the ink input tube.

[0010] In one embodiment, an ink filter is provided on the ink output tube.

[0011] In one embodiment, a liquid level sensor is provided inside the ink container, and the liquid level sensor is electrically connected to the control mechanism.

[0012] In one embodiment, an alarm is provided on the ink drum, and the alarm is electrically connected to the controlled mechanism.

[0013] In one embodiment, the alarm is a buzzer.

[0014] In one embodiment, the alarm is a flashing alarm.

[0015] In one embodiment, a temperature sensor is provided inside the ink container, and the temperature sensor is electrically connected to the control mechanism.

[0016] In one embodiment, a flow meter is provided on the ink input tube.

[0017] In one embodiment, a flow meter is provided on the ink output tube.

[0018] During operation, the aforementioned highly stable ink delivery equipment uses a diaphragm pump air source to supply air to the ink diaphragm pump. This air source draws ink from the ink container into the ink output pipe via the ink inlet pipe and the ink extraction pipe, and then delivers it to the external ink tank. Once the preset amount of ink is added to the external ink tank, the solenoid valve closes. After the solenoid valve closes, the reciprocating speed of the diaphragms in the two diaphragm drive chambers of the ink diaphragm pump gradually decreases. When the Hall sensor detects that the reciprocating speed of the pressure plate on the diaphragm is lower than a preset value, the control mechanism stops the air source from operating, thus shutting down the ink diaphragm pump. This prevents excessive air pressure in the two diaphragm drive chambers from damaging the ink diaphragm pump, thereby increasing the stability of the ink delivery operation.

[0027] Please refer to the following: Figures 1 to 3 This utility model provides a highly stable ink delivery device 10, which includes: an ink diaphragm pump 100, a diaphragm pump air source 200, an ink input pipe 300, an ink output pipe 400, an ink extraction pipe 500, an ink tank 600, two Hall sensors 700, and a control mechanism 800.

[0028] The output end of the diaphragm pump air source 200 is connected to the air inlet end of the ink diaphragm pump 100. The input end of the ink diaphragm pump 100 is connected to the ink output pipe 400 through the ink input pipe 300. In this embodiment, an ink filter 310 is provided on the ink input pipe 300. A flow meter 320 is provided on the ink input pipe 300. The ink output pipe 400 is inserted into the ink container 600. The output end of the ink diaphragm pump 100 is connected to the ink output pipe 400. In this embodiment, an ink filter 310 is provided on the ink output pipe 400. A flow meter 320 is provided on the ink output pipe 400, and a solenoid valve 410 is provided on the ink output pipe 400.

[0029] Each Hall sensor 700 is correspondingly disposed in a diaphragm drive chamber of the ink diaphragm pump 100 and connected to the housing of the ink diaphragm pump 100. The Hall sensor 700 is used to detect the position of the pressure plate 120 on the diaphragm sheet 110 in the drive chamber of the ink diaphragm pump 100.

[0030] The diaphragm pump air source 200, solenoid valve 410, and two Hall sensors 700 are all electrically connected to the control mechanism 800. It should be noted that in this embodiment, the control mechanism 800 is a lower-level machine, specifically a PLC. In another embodiment, the control mechanism 800 is a microcontroller. In other embodiments, the control mechanism 800 includes a higher-level machine and a lower-level machine, which are electrically connected. The control mechanism 800 coordinates the operation of the diaphragm pump air source 200, solenoid valve 410, and two Hall sensors 700 to increase the operational stability of the highly stable ink delivery equipment 10.

[0031] To continuously monitor the ink level in the ink container 600, in one embodiment, a liquid level sensor 610 is installed inside the ink container 600, and the liquid level sensor 610 is electrically connected to the control mechanism 800. The liquid level sensor 610 is used to detect the liquid level of the ink in the ink container 600. In this embodiment, an alarm 620 is installed on the ink container 600, and the alarm 620 is electrically connected to the control mechanism 800. The alarm 620 is a buzzer. In another embodiment, the alarm 620 is a flashing alarm 620. When the liquid level sensor 610 detects that the liquid level of the ink in the ink container 600 is lower than a preset liquid level value, the control mechanism 800 controls the alarm 620 to sound an alarm to alert the operator. Furthermore, a temperature sensor 630 is installed inside the ink container 600, and the temperature sensor 630 is electrically connected to the control mechanism 800. The temperature sensor 630 is used to detect the temperature of the ink in the ink container 600.

[0032] During operation, the aforementioned highly stable ink delivery equipment 10 supplies air to the ink diaphragm pump 100 via the diaphragm pump air source 200. The diaphragm pump air source 200 draws ink from the ink tank 600 into the ink output pipe 400 through the ink input pipe 300 and the ink extraction pipe 500, and then delivers it to the external ink tank. Once the preset amount of ink is added to the external ink tank, the solenoid valve 410 closes. After the solenoid valve 410 closes, the reciprocating speed of the diaphragm plates 110 in the two diaphragm drive chambers of the ink diaphragm pump 100 gradually decreases. When the Hall sensor 700 detects that the reciprocating speed of the pressure plate 120 on the diaphragm plate 110 is lower than a preset value, the control mechanism 800 controls the diaphragm pump air source 200 to stop working, thereby shutting down the ink diaphragm pump 100. This avoids excessive air pressure in the two diaphragm drive chambers of the ink diaphragm pump 100, preventing damage to the ink diaphragm pump 100 and thus increasing the stability of the ink delivery operation.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
