Description

Technical Field

[0001] The utility model relates to the technical field of printing ink, in particular to a printing ink filling device. Background Art

[0002] Ink is an important material for printing. It is composed of resins, pigments, fillers, additives and solvents, and is a viscous colloidal fluid formed by uniform mixing and repeated rolling. After the printing ink is prepared, it needs to be filled and sealed by filling equipment before it can be stored and transported. Existing filling equipment aligns the filling head with the mouth of the container and directly injects the ink by pumping. However, due to the large height difference between the printing ink and the bottom of the container, the printing ink easily stirs up a large number of bubbles when it is injected into the container. When the printing ink liquid level is high, it is easy to splash, causing damage to the sanitary environment around the filling equipment. At the same time, if the bubbles on the printing ink liquid surface flow out of the container mouth, it will affect the container seal. In addition, the bubbles contained in the printing ink will affect the printing quality when it is put into printing operation. Utility Model Content

[0021] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0022] like Figure 1-4 As shown, a filling device for printing ink includes a support platform 1, a bracket 4, a lifting mechanism and a filler. The bracket 4 is rotatably connected to the upper end of the support platform 1. After the bracket 4 is rotated to a certain angle, it is fixed by a bolt 5. The lifting mechanism is installed in the bracket 4. The lower end of the lifting mechanism is connected to the filler. The height of the filler is adjusted by the lifting mechanism, and the lower end of the filler can be extended into the ink bottle to prevent the printing ink from splashing or arousing a large number of bubbles due to a large height difference between the printing ink and the bottom of the container, thereby protecting the sanitary environment around the filling operation, ensuring that there is no bubble influence when the container is subsequently sealed, and achieving smooth packaging. The support platform 1 includes an inserting plate 102 and a base plate 101. The base plate 101 is provided with an inserting slot, and the inserting plate 102 is inserted into the inserting slot, which makes installation convenient and quick. The sides of the base plate 101 and the inserting plate 102 are both provided with insertion holes 3, and pins can be installed in the insertion holes 3. By cooperating between different insertion holes 3, the overall height of the device can be adjusted, that is, the height of the filler can be adjusted to prevent the ink bottle from colliding with the filler during horizontal transportation, and to ensure that the drop is not too large after the lower end of the filler is inserted into the ink bottle.

[0023] In the above embodiment, the lifting mechanism includes a motor 6, a screw rod 7, a lifting plate 10 and a cylinder 9. A guide column 8 is provided in the bracket 4, and a guide hole 1001 is provided on the lifting plate 10. The guide column 8 is slidably connected to the guide hole 1001. The guide column 8 and the guide hole 1001 can not only provide guidance for the lifting plate 10, but also provide auxiliary force to ensure the smoothness of the up and down movement of the lifting plate 10; the screw rod 7 is rotatably connected to the bracket 4, the motor 6 is installed at the upper end of the bracket 4, the output end of the motor 6 is connected to the screw rod 7, and the screw rod 7 is connected to the lifting plate 10 by a threaded transmission. The rotation of the motor 6 drives the screw rod 7, thereby driving the lifting plate 10 to achieve precise up and down movement; the cylinder 9 is installed on the lifting plate 10, and the output end of the cylinder 9 passes downward through the lifting plate 10 and is connected to the filler. After the ink bottle moves to the bottom of the filler, under the push of the cylinder 9, the lower end of the filler extends into the ink bottle for filling. A guide plate 16 is provided parallel to the lower end of the lifting plate 10. The lifting plate 10 and the guide plate 16 are connected by a vertical plate 15. A guide groove 1601 is provided in the middle of the guide plate 16. A guide rail 1102 is provided on the side of the filler. The guide rail 1102 is slidably connected to the guide groove 1601. The connection between the guide rail 1102 and the guide groove 1601 provides auxiliary force and guiding effects for the filler, so that the filler is not easily vibrated during filling and remains stable during lifting.

[0024] In the above embodiment, the filler includes a cylinder 11 and a needle 12. The upper end of the cylinder 11 is connected to the output end of the cylinder 9. A cavity connected to the lower end is provided in the cylinder 11 for storing and transporting printing ink. An injection port 1101 connected to the cavity is opened on the side of the cylinder 11 for injecting printing ink. The needle 12 is connected to the cavity at the lower end of the cylinder 11 by a thread. The needle 12 is a hollow structure. The needle 12 is divided into multiple models according to different inner diameters and lengths. The appropriate model of needle 12 can be selected for filling according to the height of the ink bottle, the viscosity of the printing ink, etc.; the filler also includes a three-way valve 13. The three-way valve 13 has an inlet and two outlets. The inlet is for pumping printing ink. One outlet of the three-way valve 13 is connected to the injection port 1101 for horizontally transporting printing ink to the cavity in the cylinder 11. The other outlet is threadedly connected to a plug 14. After removing the plug 14, it can be used for discharge inspection or for passing a cleaning agent containing alcohol during cleaning. The buffer also includes a buffer structure, which is mounted on the lower end of the cylinder 11. The needle 12 passes through the buffer structure. When the lifting mechanism pushes the buffer downward, the buffer structure first abuts the upper end of the ink bottle, preventing the filler from striking the ink bottle and damaging the bottle mouth or the buffer, or causing the ink bottle to deviate from the filling position, thereby affecting the accuracy of subsequent sealing. The buffer structure includes a nut 17, a spring 18, and a retaining ring 19. The nut 17 is threadedly connected to the lower end of the cylinder 11. The upper end of the spring 18 is fixedly connected to the nut 17 and the lower end is fixedly connected to the retaining ring 19. The needle 12 passes through the spring 18 and retaining ring 19. The position of the buffer structure on the buffer, thereby adjusting the buffer stroke, can be adjusted by using the nut 17. The entire buffer structure can also be removed when removing the needle 12 for easier operation. Under the action of the buffer structure, the retaining ring 19 abuts the bottle mouth of the ink bottle. The reaction force after compressing the spring 18 fixes the ink bottle, ensuring the stability of the ink bottle during the filling process. The upper end of the needle 12 is provided with a wrench position 1201 to facilitate the operator to disassemble and assemble the slender needle 12.

[0025] Description of the working method of this utility model:

[0026] The device is installed on the side of the ink bottle conveyor line. After securing the lower end of the support platform 1, the filler's needle 12 is aligned with the center line of the ink bottle conveyor by adjusting the angle of the support 4. The support 4 is then tightened with bolts 5 to prevent it from deviating from the correct filling position. The height of the support platform 1 is then adjusted so that the lower end of the needle 12 is initially slightly higher than the upper end of the ink bottle. This reduces the lifting stroke during filling while avoiding interference and improving filling efficiency. The prepared printing ink is connected to the inlet of the three-way valve 13 of the device through a pipe. After the printing ink is pumped into the cavity of the cylinder 11, it is pressurized by the action of the tapered cavity and ultimately discharged downward from the needle 12.

[0027] Before filling begins, the motor 6 rotates to control the lifting plate 10 to move to its lower limit position, and the cylinder 9 controls the filler to move to its upper limit position. At this time, the needle 12 of the filler is slightly higher than the upper end of the ink bottle. After the filling starts, the ink bottle is transported horizontally on the conveyor line. When it reaches the bottom of this device, the ink bottle is positioned and clamped by an external positioning and clamping device. Then the cylinder 9 pushes the needle 12 of the filler down into the ink bottle. At this time, the needle 12 is slightly higher than the bottom of the ink bottle; the printing ink is pumped into the cavity of the filler cylinder 11 through the pipeline, and then injected into the ink bottle along the needle 12. At the same time, the motor 6 rotates to control the lifting plate 10 to rise, and is linked with the external device for pumping printing ink to keep the needle 12 always higher than the horizontal surface of the printing ink in the ink bottle; under precise control, the height difference between the needle 12 and the horizontal surface of the printing ink remains basically unchanged, maintaining a stable filling state, minimizing the splashing of printing ink or the stirring of bubbles, protecting the sanitary environment around the filling operation, and ensuring that the subsequent sealing of the container is not affected or less affected by bubbles, thereby achieving smooth packaging. After each ink bottle is filled, the needle 12 is still inside the ink bottle. At this time, the cylinder 9 needs to pull the filler to reset to the upper limit position, and at the same time, the motor 6 is used to rotate and control the lifting plate 10 to move to the lower limit position, so as to pull the needle 12 out of the ink bottle and complete the overall reset, so as to carry out the filling of the next ink bottle; in the actual filling operation, since the speed of the lifting plate 10 controlled by the motor 6 is limited, the next filling operation can only be carried out after it is completely reset. Therefore, multiple sets of this device need to be used on the production line to perform alternating filling operations to realize continuous filling operations of printing ink and improve filling efficiency.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
