Description

Technical Field

[0001] This utility model relates to the field of ink-related equipment design, and in particular to an ink dispensing device. Background Technology

[0002] Printing inks are widely used in packaging, textiles, and electronics, among other industries. They effectively adhere to various materials to create images and text. There are many types of printing inks, the vast majority of which are liquid, and they are typically stored in containers.

[0003] However, since the ink containers used for storing ink are usually large in size and often contain a large amount of ink, it is not convenient for users to take out a specific amount of ink for use. On the other hand, as the ink is used repeatedly, the ink level will gradually change. It is difficult to effectively adapt the ink taking out to the different ink levels, resulting in poor flexibility. Utility Model Content

[0004] The purpose of this invention is to provide an ink dispensing device that can solve one or more of the above-mentioned problems.

[0005] According to one aspect of the present invention, an ink dispensing device is provided, comprising a unit suction head, a unit pump, a hose, a suction head base, a pump base, a fixed base, a moving mechanism, a first transmission mechanism, a second transmission mechanism, a first servo motor, and a second servo motor.

[0006] The unit suction head is mounted on a suction head holder, which is slidably mounted on a fixed base.

[0007] The unit pump is mounted on a pump base, which is fixedly mounted on a fixed base. The unit pump is connected to the unit suction head via a flexible hose.

[0008] Both the first servo motor and the second servo motor are mounted on a fixed base. The first servo motor is connected to the moving mechanism via a first transmission mechanism, and the second servo motor is connected to the suction head base via a second transmission mechanism.

[0009] The moving mechanism is slidably mounted on the fixed base and connected to the unit pump.

[0010] The beneficial effects of this utility model are as follows: This utility model can be used to extract ink from a material container. By contacting the unit suction head with the ink, the first servo motor drives the unit pump to work, thereby extracting the ink. Since the servo motor can effectively perform precise movements, quantitative extraction of ink can be achieved. On the other hand, in this utility model, since the hose has a certain degree of flexibility, a certain amount of movement is allowed between the unit suction head and the unit pump. Therefore, this utility model can also drive the suction head seat to move to a certain extent through the second servo motor, thereby adjusting the height of the suction head to match the liquid level of the ink in the material container, which is highly flexible.

[0011] In some embodiments, the moving mechanism includes a moving block, a support plate, rollers, and a connecting rod. The moving block is connected to the support plate, the connecting rod is connected to the support plate, the rollers are rotatably mounted on the connecting rod, and the fixed base has a guide groove on which the rollers are rotatably embedded. The support plate can move as the rollers roll on the guide groove, thereby causing the moving block connected to the support plate to move accordingly.

[0012] In some embodiments, the first transmission mechanism includes a first lead screw and a first nut. The first lead screw is connected to a first servo motor, and the first nut is threaded onto the first lead screw. The moving block has a receiving groove, and the first nut is disposed in the receiving groove and connected to the moving block. The first servo motor can drive the first lead screw to rotate, thereby allowing the first nut disposed on the first lead screw to move along the first lead screw, thus driving the moving block connected to the nut to move.

[0013] In some embodiments, the second transmission mechanism includes a second lead screw, a second nut, a connecting plate, and a guide wheel. The second lead screw is connected to a second servo motor. The second nut is threaded onto the second lead screw. The connecting plate is connected to the second nut. The guide wheel is connected to the connecting plate. The fixed base is provided with a guide rail, and the guide wheel is rotatably disposed in the guide rail. The connecting plate is connected to the suction head holder. The second servo motor can drive the second lead screw to rotate, thereby allowing the second nut mounted on the second lead screw to move along the second lead screw, thus enabling the suction head holder connected to the second nut via the connecting plate to move accordingly.

[0014] In some embodiments, there are multiple unit suction heads, unit pumps, and hoses, and the multiple unit suction heads and multiple unit pumps are respectively connected one-to-one through multiple hoses.

[0015] In some embodiments, the unit pump includes a pump body, a piston, and a piston rod. One end of the piston rod is connected to the piston, which is slidably disposed within the pump body. The other end of the piston rod has a rod head. The moving mechanism has multiple mounting holes. Multiple unit pump bodies are fixedly embedded in a pump base, and the rod heads of multiple unit pumps are correspondingly fitted into the multiple mounting holes. This allows the user to adjust the ink absorption limit of this invention by disassembling the connection between a specific rod head and the moving mechanism, thereby preventing the moving mechanism from driving the corresponding unit pump and better matching different needs.

[0016] In some embodiments, the present invention further includes a slider, the suction head seat is connected to the slider, the fixed base is provided with a groove, and the slider is slidably disposed on the groove.

[0028] The pump base 5 is fixedly mounted on the fixed base 6 by screws, and the pump base 5 is provided with a clamping block. The clamping block clamps the pump body 21 of each unit pump 2 and is fixed by screws, so that the pump body 21 of the unit pump 2 is fixedly embedded in the pump base 5.

[0029] The moving mechanism 7 includes a moving block 71, a support plate 72, rollers 73, and connecting rods 74. The moving block 71 is fixedly connected to the support plate 72 by screws. Preferably, there are four connecting rods 74 and four rollers 73.

The four rollers 73 are rotatably mounted on the four connecting rods 74. The fixed base 6 has guide grooves 61 on both sides, and the rollers 73 can be rolled and embedded in the guide grooves 61, so that the moving mechanism 7 can be slidably mounted on the fixed base 6.

[0030] The moving block 71 of the moving mechanism 7 is provided with a plurality of mounting holes 711. The number of mounting holes 711 is equivalent to the number of unit pumps 2, and preferably eight. The rod heads 221 of the piston rods 22 of the eight unit pumps 2 are fitted into the eight mounting holes 711 one by one by screws, so that the moving block 71 of the moving mechanism 7 is connected to each unit pump 2.

[0031] The flexible hose (not shown in the figure) can be a commercially available PVC pipe, and the hose should have a certain degree of bendability. Multiple hoses can be used, the number of which should be equivalent to the number of unit suction heads 1. In this embodiment, eight hoses are preferred. One end of each of the eight hoses is connected to the pump body 21 of one of the eight unit pumps 2, and the other end of each hose is connected to one of the eight unit suction heads 1. That is, the eight unit suction heads 1 and the eight unit pumps 2 are connected and communicate with each other through the eight hoses.

[0032] The suction head holder 4 is slidably mounted on the fixed base 6. Preferably, this ink dispensing device further includes a slider 30. The suction head holder 4 is fixedly connected to the slider 30 by screws. The fixed base 6 may have a sliding groove, and in this embodiment, the sliding groove may share the same groove with the guide groove 61. The slider 30 is slidably embedded in the sliding groove. The pump base 5 is also provided with a limiting hole 51. The slider 30 is disposed in the limiting hole 51, and the movement of the slider 30 cannot disengage from the limiting hole 51. That is, the limiting hole 51 can effectively limit the movable range of the slider 30.

[0033] The bodies of the first servo motor 10 and the second servo motor 20 are both fixedly mounted on the mounting base 6 with screws.

[0034] The first servo motor 10 is connected to the moving mechanism 7 via the first transmission mechanism 8. Preferably, the first transmission mechanism 8 includes a first lead screw 81 and a first nut 82. The first lead screw 81 is connected to the output shaft of the first servo motor 10 via a coupling, so that the first servo motor 10 can drive the first lead screw 81 to rotate. The first nut 82 is threadedly mounted on the first lead screw 81, and the moving block 71 of the moving mechanism 7 is provided with a receiving groove 712. The first nut 82 is embedded in the receiving groove 712, and the first nut 82 is fixedly connected to the moving block 71 by screws, so that the first nut 82 is restricted to linear movement only.

[0035] The second servo motor 20 is connected to the suction head seat 4 via the second transmission mechanism 9. Preferably, the second transmission mechanism 9 includes a second lead screw 91, a second nut 92, a connecting plate 93, and guide wheels 94. The second lead screw 91 is connected to the output shaft of the second servo motor 20 via a coupling, so that the second servo motor 20 can drive the second lead screw 91 to rotate. The second nut 92 is threadedly installed on the second lead screw 91. The connecting plate 93 is fixedly connected to the second nut 92 by screws, and the connecting plate 93 is also connected to the suction head seat 4 by screws, so that the second nut 92 is restricted to linear movement only. At the same time, there can be multiple guide wheels 94, which are respectively connected to the connecting plate 93 by rods. The connected guide wheels 94 can rotate, and the fixed seat 6 is also provided with a guide rail 62, in which the guide wheels 94 are rotatably disposed, that is, the guide wheels 94 can roll along the guide rail 62.

[0036] This ink dispensing device may also include valves, which can be manual valves or solenoid valves, etc. Preferably, there are eight valves, each fixedly connected to one of the eight unit pumps 2 by screws. Simultaneously, each of the eight valves can be engaged with one of the eight hoses. That is, the valves are configured to be positioned between the unit pumps 2 and the hoses, controlling the connection between the unit pumps 2 and the hoses. The valves facilitate the shut-off of the unit pumps 2 and hoses when needed, i.e., cutting off the connection between the unit pumps 2 and the unit suction head 1, preventing the unit suction head 1 from accidentally drawing in or discharging ink.

[0037] This ink dispensing device can be used to dispense ink from a material container. When in use, its fixed base 6 can be connected to an external machine, and the fixed base 6 can also be connected to the actuating device of the external machine, such as a linear cylinder, so as to facilitate the driving of the fixed base 6 to make large-scale movements.

[0038] When ink needs to be dispensed, external machinery is activated to bring the ink dispensing device close to the ink to be dispensed. This activates the second servo motor 20, which in turn drives the second lead screw 91 to rotate. The rotation of the lead screw 91 causes the second nut 92 to move along it, causing the connecting plate 93 connected to the second nut 92 to move accordingly. The suction head holder 4 connected to the connecting plate 93 also moves accordingly, allowing the unit suction head 1 on the suction head holder 4 to extend into the ink. Simultaneously, the movement of the connecting plate 93 causes the guide wheel 94 to roll along the guide rail 62, guiding the movement of the suction head holder 4.

[0039] Then, the first servo motor 10 is driven to work. The first servo motor 10 can drive the first lead screw 81 to rotate. The rotation of the first lead screw 81 can cause the first nut 82 to move along the first lead screw 81. The support plate 72 connected to the first nut 82 can move accordingly. Then the moving block 71 connected to the support plate 72 can also move accordingly. And the movement of the support plate 72 can cause the roller 73 to roll along the guide groove 61 to guide the movement of the support plate 72.

[0040] As the moving block 71 moves, the piston rods 22 of each unit pump 2 connected to the moving block 71 can move backward accordingly to absorb ink. The user can control the speed and working time of the first servo motor 10 to precisely control the moving distance of the moving block 71, that is, effectively control the amount of ink absorbed to achieve quantitative absorption.

[0041] In addition, during the ink absorption process, if the ink level changes, the second servo motor 20 can be driven to work accordingly, so that the suction head 4 can move, thereby ensuring that the unit suction head 1 on the suction head 4 is always inserted into the ink, effectively matching the ink level.

[0042] Once the ink intake reaches the required level, the operation of the first servo motor 10 can be stopped, and the ink taking device can be moved to the position where ink needs to be used. The first servo motor 10 can then be restarted, causing the first lead screw 81 to rotate. At this time, the first lead screw 81 can rotate in the opposite direction to the intake position, so that the piston rods 22 of each unit pump 2 connected to the moving block 71 can move forward accordingly, so that the ink can be output for use.

[0043] In actual use, users can select the number of unit pumps 2 to use according to the amount of ink required. When not all unit pumps 2 need to be used, users can disassemble the connection between the lever head 221 and the moving block 71 of the unit pump 2 that is not in use, so that the unit pump 2 does not perform ink suction, further improving the flexibility of this ink dispensing device.

[0044] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
