Description

Technical Field

[0001] This utility model belongs to the technical field of multicolor wide-format flexographic printing presses, and particularly relates to a rapid ink switching device for multicolor wide-format flexographic printing. Background Technology

[0002] Multicolor wide-format flexographic printing press is an industrial printing equipment based on flexographic printing technology, which has the ability to print multiple colors and has a wide printing area. It is widely used in packaging, labeling, non-woven fabrics, plastic films and other fields.

[0003] For example, Chinese patent CN221049280U discloses a multi-color wide-format flexographic printing press, including a support assembly, a motor, a dyeing roller, a roller body, a mounting structure, a drive gear, and a driven gear. The mounting structure, including a printing plate, is installed inside the roller body. The printing plate is inserted into the roller body, and a limiting structure, including a sleeve, a spring, and a limiting block, is provided inside the roller body. This invention, through the setting of the limiting block and limiting hole, allows for easy installation and removal of the printing plate when it needs to be disassembled. Loosening the nut and moving the first screw moves the limiting block out of the limiting hole, thus releasing the limiting effect on the printing plate.

[0004] The aforementioned patent has the following problems: This patent has some drawbacks in its use. For example, when the ink storage container is low, the device needs to be refilled, causing it to stop operating and restart only after the ink has been added, thus reducing efficiency. Furthermore, if the newly added ink is not thoroughly mixed with the remaining ink in the printing press's ink trough, it can lead to uneven distribution of pigments, solvents, and additives. Therefore, we propose a rapid ink switching device for multi-color wide-format flexographic printing. Utility Model Content

[0005] The purpose of this invention is to provide a rapid ink switching device for multi-color wide-format flexographic printing to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a rapid ink switching device for multi-color wide-format flexographic printing. The rapid ink switching device for multi-color wide-format flexographic printing includes a multi-color wide-format flexographic printing machine, a storage housing, and an ink jetting tube, and further includes: Two storage chambers are provided, both of which are located inside a storage shell. The storage shell is fixedly installed on the top of the multicolor wide-format flexographic printing press. The spray pipe is fixedly installed at the bottom of the storage shell. Two rotating columns are rotatably installed in each of the two storage chambers. Several stirring blades are fixedly installed on each of the four rotating columns. A plurality of through holes are provided, all of which are provided inside the storage shell. The plurality of through holes are respectively connected to two storage cavities. Sliding plates are slidably installed in both storage cavities, and the two sliding plates are respectively in close contact with the plurality of through holes. A drive assembly, located on the storage housing, is used to drive the four rotating columns to rotate. A power assembly, located within the storage housing, is used to drive two sliding plates to slide.

[0007] In this technical solution, when the ink in one of the storage chambers is about to run out, the power component can drive two sliding plates to slide, blocking several through holes on the left side. The ink in one of the storage chambers will no longer be supplied to the spray tube, while the ink in the other storage chamber will be supplied to the spray tube through several through holes on the right side. This allows for seamless switching and ensures that the multi-color wide-format flexographic printing press will not run out of ink during use. The user can inject ink into one of the storage chambers. The drive components can drive several rotating columns to rotate, which in turn drive several stirring blades to rotate. These stirring blades can stir the ink in the two storage chambers, preventing pigment sedimentation or clumping and avoiding uneven color in some areas.

[0008] In the above technical solution, the driving component further includes: The power chamber is located inside the storage shell. A motor is fixedly mounted on the storage shell. The output shaft of the motor passes through the storage shell and extends into the power chamber. A worm gear is fixedly mounted on the output shaft of the motor. Four worm wheels are meshed on one side of the worm gear. The lower ends of the four worm wheels all pass through the power chamber and are coaxially connected to four rotating columns. The worm gear and the four worm wheels are rotatably connected to the power chamber.

[0009] In this technical solution, the motor is started, and the motor is powered on and drives the worm gear to rotate. The worm gear drives several worm wheels that mesh with it to rotate. The worm wheels drive several rotating columns to rotate. The rotating columns drive several stirring blades to rotate. The stirring blades can stir the ink in the two storage chambers to avoid pigment sedimentation or clumping and prevent uneven color in some areas.

[0010] In the above technical solution, the power component further includes: A sliding groove is formed inside the storage shell. A gear is rotatably installed inside the sliding groove. Racks are meshed on both sides of the gear. The two racks are fixedly connected to two sliding plates respectively. A fixed post is fixedly installed at one end of a gear. One end of the fixed post passes through a sliding groove and extends to the outside. A limiting groove is formed inside the storage shell and at the top of the fixed post. A limiting rod is slidably installed in the limiting groove. A spring fixed to the inner wall of the limiting groove is fixedly installed at the top of the limiting rod. Two grooves are formed on the fixed post. The lower end of the limiting rod extends into the corresponding groove and is inserted into the corresponding groove. Both racks are slidably connected to the sliding groove. The fixed post is rotatably connected to the sliding groove.

[0011] In this technical solution, when the ink in one of the storage chambers is about to run out, the limiting rod is pulled upwards and slides. The limiting rod compresses the spring and contracts. After the lower end of the limiting rod disengages from the groove, the fixed column rotates forward and drives the gear to rotate forward. The gear drives the two racks meshing with it to slide, and the two racks drive the two sliding plates to slide respectively. After the gear rotates 90° forward, several through holes on the left side are blocked by the left sliding plate, and the ink in one of the storage chambers no longer supplies ink to the spray tube. At the same time, the ink in the other storage chamber supplies ink to the spray tube through several through holes on the right side, allowing for seamless switching and ensuring that the multi-color wide-format flexographic printing press will not experience ink interruption during use. Then, the fixed column is released, and under the action of the spring rebound force, the limiting rod slides downwards and inserts into the groove, which can fix the position of the fixed column and the gear. At the same time, the positions of the two racks and the two sliding plates are also fixed, ensuring that the ink in the other storage chamber can supply ink to the spray tube through several through holes on the right side. The user can then inject ink into one of the storage chambers.

[0012] In the above technical solution, furthermore, an operating panel is fixedly installed at one end of the fixed column.

[0013] In this technical solution, the control panel allows staff to easily rotate the fixed column.

[0014] In the above technical solution, further, a plurality of the stirring blades are distributed in a ring at equal intervals on the corresponding rotating column.

[0015] In this technical solution, several stirring blades can stir the ink in the two storage chambers to prevent pigment sedimentation or clumping and to prevent uneven color in some areas.

[0016] In the above technical solution, the output shaft of the motor is further rotatably connected to the storage shell and the power chamber.

[0017] In this technical solution, it is ensured that the output shaft of the motor can rotate within the storage shell and the power chamber.

[0018] In the above technical solution, a sealing plug is further installed on the top of each of the two storage cavities.

[0019] In this technical solution, the sealing plug ensures that dust will not enter the storage cavity and facilitates the addition of ink to the storage cavity.

[0020] The beneficial effects of this utility model are: 1. This multi-color wide-format flexographic printing ink rapid switching device, when the ink in one of the storage chambers is about to run out, can drive two sliding plates to slide through the set power component. Several through holes on the left side are blocked by the left sliding plate, so the ink in one of the storage chambers will no longer be supplied to the spray tube. At the same time, the ink in the other storage chamber will be supplied to the spray tube through several through holes on the right side. It can switch seamlessly and ensure that the multi-color wide-format flexographic printing press will not run out of ink during use.

[0021] 2. The multi-color wide-format flexographic printing ink rapid switching device, through the set drive component, can drive several rotating columns to rotate, and the several rotating columns can drive several stirring blades to rotate. The several stirring blades can stir the ink in the two storage chambers to avoid pigment precipitation or clumping and prevent local color inconsistencies. Attached Figure Description

At the same time, the positions of the two racks 15 and the two sliding plates 8 are also fixed, ensuring that the ink in the other storage chamber 3 can be supplied to the nozzle 9 through several through holes 7 on the right side. Finally, the sealing plug 6 is removed, and the user can inject ink into one of the storage chambers 3. Simultaneously, the motor 10 is started, and the motor 10 is powered on and drives the worm gear 11 to rotate. The worm gear 11 drives the meshing worm wheels 12 to rotate. The worm wheels 12 drive the rotating columns 4 to rotate, and the rotating columns 4 drive the stirring blades 5 to rotate. The stirring blades 5 can stir the ink in the two storage chambers 3 to avoid pigment sedimentation or clumping and to prevent uneven color in some areas.
