Description

Technical Field

[0001] This utility model relates to the field of ink dispensing technology, and in particular to ink dispensing equipment. Background Technology

[0002] Ink is a viscous, colloidal fluid made by repeatedly rolling together a uniform mixture of resin, pigment, and solvent. It is an important material used in printing. Ink is used to transfer text and images onto a substrate through printing, inkjet printing, and other methods.

[0003] Typically, workers first fill the produced ink into large-capacity ink cans, then distribute the ink from the ink cans into smaller-capacity dispensing containers. Subsequently, workers need to weigh the dispensed containers and the ink to ensure that the ink volume in each container is approximately the same, thus facilitating the subsequent transportation and sale of the ink.

[0004] However, after weighing, if the ink in the dispensing container exceeds the preset weight, workers need to remove the excess ink; if the ink in the dispensing container does not reach the preset weight, workers need to add ink to reach the preset weight. These operations are cumbersome, increasing the workload for workers and reducing production efficiency. Furthermore, ink inevitably contains impurities after production, and directly dispensing unfiltered ink into the dispensing container will affect printing quality. Utility Model Content

[0026] refer to Figures 1 to 4An ink dispensing device according to a preferred embodiment of the present invention will be described in detail below, the ink dispensing device being used to dispense ink from an ink tank 800 into at least one dispensing container 900.

[0027] The ink dispensing equipment includes an ink extraction device 10 and an ink delivery device 20.

[0028] The ink supply device 20 includes a first ink supply tube 21. The first ink supply tube 21 forms a first ink supply channel 2101, a first ink inlet 2102 communicating with the first ink supply channel 2101, and a first ink outlet 2103 communicating with the first ink supply channel 2101.

[0029] The ink extraction device 10 includes a first ink pump 11. The first ink pump 11 is connected to the ink tank 800 via a pipeline. The first ink pump 11 is installed at one end of the first ink supply pipe 21 that forms the first ink inlet 2102. One end of the first ink supply pipe 21 that forms the first ink outlet 2103 faces the opening of the dispensing container 900. In this way, the ink in the ink tank 800 is drawn from the first ink inlet 2102 to the first ink outlet 2103 by the first ink pump 11, and then the ink flows from the first ink outlet 2103 to the dispensing container 900.

[0030] In one example, the first ink pump 11 is implemented as a negative pressure pump.

[0031] The ink dispensing equipment also includes a control device 30. The control device 30 includes a control valve 31. The control valve 31 is installed in the first ink supply tube 21. The control valve 31 is used to control the opening and closing of the ink flow path in the first ink supply channel 2101 and the amount of ink output from the first ink inlet 2102 to the first ink outlet 2103.

[0032] Furthermore, the ink dispensing equipment also includes a weighing element 40. The weighing element 40 is disposed below the first ink outlet 2103 of the first ink supply tube 21. The dispensing container 900 is placed on the weighing element 40. The weighing element 40 is used to measure the weight of the empty dispensing container 900 and the dispensing container 900 containing ink.

[0033] In one embodiment, a worker places an empty dispensing container 900 onto the weighing device 40. The worker then opens the control valve 31 and the first ink pump 11, causing the ink in the ink tank 800 to be drawn by the first ink pump 11 through the first ink supply channel 2101 from the first ink inlet 2102 towards the first ink outlet 2103. The ink then flows from the first ink outlet 2103 to the dispensing container 900. During this process, the worker observes the value measured by the weighing device 40. When the weighing device 40 is about to display a predetermined value, the worker manually closes the control valve 31 and the first ink pump 11 to complete the ink dispensing. By setting the weighing device 40, the worker can directly observe the weight change of the dispensing container 900 during the dispensing process, without needing to measure the weight of the dispensing container 900 after dispensing to select products that do not meet the weight standard. This ink dispensing equipment simplifies the dispensing steps, improving production efficiency and reducing the workload of workers.

[0034] In this embodiment, the weighing element 40 is implemented as an electronic scale.

[0035] Preferably, the control device 30 further includes a controller 32. The weighing element 40 is communicatively connected to the controller 32, and the control valve 31 is controllably connected to the controller 32.

[0036] Specifically, during the ink dispensing process, when the weighing device 40 reaches a predetermined value, the controller 32 acquires the weight signal of the dispensing container 900 containing ink measured by the weighing device 40 and controls the control valve 31 to close, thereby blocking the flow of ink from the first ink outlet 2103 to the dispensing container 900. Subsequently, the worker removes the dispensing container 900 containing ink, which has reached the preset weight, from the weighing device 40 and places another empty dispensing container 900 on the weighing device 40. At this time, the controller 32 controls the control valve 31 to open, allowing ink to flow through the first ink outlet 2103 to the dispensing container 900. In this way, the worker does not need to constantly monitor the changes in the value of the weighing device 40 to ensure that the control valve 31 automatically closes after the ink in the dispensing container 900 reaches the predetermined weight, eliminating the need for manual closure of the control valve 31. Compared to the previous embodiment, by setting the controller 32, the automation level of the ink dispensing equipment is further improved, increasing work efficiency.

[0037] In this embodiment, the weighing element 40 is implemented as a weight sensor.

[0038] Furthermore, the ink dispensing equipment also includes a splash guard 50. The splash guard 50 includes a lifting mechanism 51. The lifting mechanism 51 includes a fixing member 511 and a moving member 512. The moving member 512 is mounted on the fixing member 511 and is vertically movable. One end of the first ink supply tube 21 forming the first ink outlet 2103 is mounted on the moving member 512.

[0039] Specifically, when the ink in the first ink supply channel 2101 flows from the first ink outlet 2103 to the dispensing container 900, as the ink level in the dispensing container 900 gradually rises, the worker manually moves the moving part 512 upwards to keep the first ink outlet 2103 at a predetermined height from the ink level in the dispensing container 900, so as to prevent the ink from splashing out due to excessive height difference between the first ink outlet 2103 and the ink level in the dispensing container 900.

[0040] Preferably, the first ink supply tube 21 is configured to be retractable at the end forming the first ink outlet 2103, so that when the moving member 512 drives the first ink supply tube 21 to move vertically, the end forming the first ink outlet 2103 of the first ink supply tube 21 can provide deformation during the movement.

[0041] In one example, the lifting mechanism 51 is implemented as a lead screw structure; the fixing member 511 is implemented as a threaded rod; and the moving member 512 is implemented as a nut.

[0042] Preferably, the lifting mechanism 51 further includes a lifting drive component 513. The splash-proof device 50 further includes a liquid level detector 52. The movable component 512 is connected to the lifting drive component 513. The lifting drive component 513 is used to drive the movable component 512 to move vertically. The liquid level detector 52 is installed on the movable component 512. The liquid level detector 52 is used to detect the ink level in the dispensing container 900. The liquid level detector 52 is communicatively connected to the controller 32, and the lifting drive component 513 is controllably connected to the controller 32. The controller 32 is configured to control the start and stop of the lifting drive component 513 based on the liquid level height measured by the liquid level detector 52.

[0043] Specifically, as the ink level in the dispensing container 900 gradually rises, the controller 32 controls the lifting drive 513 to start, so that the moving part 512 is driven by the lifting drive 513 to move the liquid level detector 52 vertically, so that the ink level value measured by the liquid level detector 52 is always kept near the predetermined liquid level value, and the first ink outlet 2103 and the liquid surface are always kept within the predetermined range, thereby preventing ink from splashing out of the dispensing container 900.

[0044] When the liquid level detected by the liquid level detector 52 is lower than the predetermined liquid level, that is, when the height difference between the first ink outlet 2103 and the ink level in the dispensing container 900 is too large, the controller 32 controls the lifting drive 513 to drive the moving part 512 downward until the liquid level detector 52 returns to the predetermined liquid level. By setting the lifting drive 513, the liquid level detector 52, and the controller 32, not only is the workload of workers reduced, but the anti-splash effect is also enhanced, and the automation level of the ink dispensing equipment is further improved.

[0045] In this embodiment, the lifting drive 513 is implemented as a motor; the liquid level detection component 52 is implemented as a liquid level sensor.

[0046] Preferably, the ink supply device 20 further includes a second ink supply tube 22. The second ink supply tube 22 is connected to the first ink supply tube 21 and communicates with the first ink supply channel 2101. The second ink supply tube 22 forms a second ink outlet 2201 at the end away from the end connected to the first ink supply tube 21.

[0047] In one embodiment, after one end of the first ink supply tube 21 forming the first ink outlet 2103 is blocked by ink, one end of the second ink supply tube 22 forming the second ink outlet 2201 faces the opening of the empty dispensing container 900. In this way, the ink in the ink tank 800 flows from the first ink inlet 2102 to the second ink outlet 2201 via the first ink supply channel 2101, and then flows from the second ink outlet 2201 to the dispensing container 900. By setting the second ink supply tube 22, the ink dispensing process of the ink dispensing equipment can be ensured to proceed normally after the first ink outlet 2103 is blocked.

[0048] The ink dispensing equipment also includes a filter device 60. The filter device 60 is detachably connected to the first ink supply tube 21 and communicates with the first ink supply channel 2101. The filter device 60 is used to filter impurities in the ink flowing from the first ink outlet 2103 to the first ink supply channel 2101. By providing the filter device 60, the purity of the ink dispensed into the dispensing container 900 is improved, thereby resulting in higher printing quality.

[0049] In one example, the filtration device 60 is implemented as a backwash filter.

[0050] Furthermore, the ink extraction device 10 also includes a second ink pump 12. The second ink supply tube 22 is connected to the second ink pump 12.

[0051] In one embodiment, the filter device 60 is disposed on the pipeline through which ink flows from the first ink inlet 2102 to the second ink outlet 2201, and the filter device 60 is connected to the second ink supply pipe 22. After the filter device 60 is clogged by impurities in the ink, one end of the second ink supply pipe 22 forming the second ink outlet 2201 extends into a container holding impurity-free ink. The second ink pump 12 is used to reverse-draw the impurity-free ink from the container from the second ink outlet 2201 towards the first ink inlet 2102, thereby flushing the filter device 60. This causes the impurity-free ink and the impurities clogged in the filter device 60 to flow together towards the first ink inlet 2102, and finally back from the first ink inlet 2102 to the ink tank 800, thus ensuring the unobstructed flow of the filter device 60.

[0052] In one example, the second ink pump 12 is implemented as a negative pressure pump.

The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
