Description

Technical Field

[0001] The present application relates to the printing of packaging bags, and in particular to the cleaning of ink pipelines of inkjet printers. Background Art

[0002] After the powder product is packed into the packaging bag, it is necessary to print the mark and date on the surface of the packaging bag. The printing operation can be completed using an inkjet printer. The inkjet printer has an ink delivery pipeline for delivering ink to the nozzle to complete the printing of the mark and date. In order to prevent the ink from drying and agglomerating in the delivery pipeline, the pipeline needs to be cleaned regularly or as needed.

[0003] Usually, it is necessary to manually use matching tools to connect the original ink inlet and inject the cleaning agent into the ink delivery pipeline for cleaning. The operation is cumbersome and inefficient, and the unstable cleaning pressure can easily cause bubbles in the pipeline. Utility Model Content

[0004] The purpose of this application is to develop an ink pipeline cleaning device to reduce operation time and improve production efficiency.

[0005] To this end, according to one aspect of the present application, a device for cleaning ink pipelines of a printer is provided, comprising a compressed air switch, a control switch, a detergent storage tank and a three-way valve, wherein a compressed air pipeline is connected to the compressed air switch, the control switch, the detergent storage tank and the three-way valve. The first inlet of the three-way valve is connected to the detergent storage tank.

[0006] Furthermore, the device also includes a gas pressure regulating valve, which is arranged between the compressed air switch and the control switch and is connected to each other via the compressed gas pipeline.

[0007] According to another aspect of the present application, a jet printer includes an ink pipeline, the jet printer ink pipeline cleaning device and an ink supply device, wherein the outlet of the three-way valve is connected to the upstream end of the ink pipeline, and the second inlet of the three-way valve is connected to the ink supply device.

[0008] The device provided by the present application is simple to operate and has high production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] 100 inkjet printer ink pipeline cleaning device, 110 compressed air switch, 120 gas pressure regulating valve, 130 control switch, 140 detergent storage tank, 150 three-way valve, 160 compressed gas pipeline

[0013] The specific implementation of the present application is described below with reference to the accompanying drawings.

[0014] like Figure 1 As shown, a device 100 for cleaning ink pipelines of a printer includes a compressed air switch 110 , a gas pressure regulating valve 120 , a control switch 130 , a detergent storage tank 140 and a three-way valve 150 , which are connected to each other through a compressed gas pipeline 160 .

[0015] In addition, the compressed air source 10 is connected to the compressed air switch 110 through the compressed air pipeline 160 .

[0016] The compressed air switch 110 is turned on, and the compressed air enters the gas pressure regulating valve 120. The gas pressure regulating valve 120 can adjust the gas pressure in the compressed gas pipeline 160 to maintain a proper gas pressure.

[0017] The control switch 130 may be a momentary switch, for example, which can be turned on and off by pressing. When the control switch 130 is pressed, the pressure-regulated air enters the cleaning agent storage tank 140 via the compressed gas pipeline 160. By controlling the pressing time, the amount of compressed gas entering can be controlled, thereby controlling the cleaning time and the amount of cleaning agent used.

[0018] The cleaning agent enters the compressed air pipeline 160 under the action of the compressed air and flows toward the three-way valve 150 .

[0019] The three-way valve 150 is a common three-way valve having two inlets and one outlet. The first inlet of the three-way valve is connected to the cleaning agent storage tank 140 through the compressed gas pipeline 160, and the outlet of the three-way valve is connected to the ink pipeline 220 of the inkjet printer. The compressed air drives the cleaning agent to enter the three-way valve 150 from the first inlet, and enter the ink pipeline 220 of the inkjet printer through the outlet, and then reach the inkjet terminal 210 to complete the cleaning.

[0020] In another embodiment, a printer includes a printer terminal 210, an ink pipeline 220, the aforementioned printer ink pipeline cleaning device 100 and an ink supply device 230, wherein the outlet of the three-way valve 150 is connected to the upstream end of the ink pipeline, the first inlet of the three-way valve is connected to the detergent storage tank 140 through the compressed gas pipeline 160, and the second inlet of the three-way valve is connected to the ink supply device 230.

[0021] When pipeline cleaning is required, the three-way valve is rotated to connect the compressed gas pipeline 160 with the outlet of the three-way valve 150, and the pressurized cleaning agent can be input into the ink pipeline 220 for cleaning. When coding is required, the three-way valve is rotated to another position, so that the ink supply device 230 is connected with the outlet of the three-way valve 150, and the cleaning agent input port can be closed, and ink is not input instead of cleaning agent, so as to perform coding.

[0022] In the above description, the details of the technical solution of the present application are explained. However, those skilled in the art will appreciate that the present application is not limited to the specific details listed in the above embodiments, but may vary within the scope defined by the claims.
