Description

An ink circulation device for a gravure printing machine Technical Field

[0001] This utility model relates to the field of gravure printing machine technology, and in particular to an ink circulation device for gravure printing machines. Background Technology

[0002] A gravure printing press is a machine for printing text and images. A modern printing press generally consists of mechanisms for mounting the plate, inking, pressing, and feeding paper (including folding). Its working principle is as follows: First, the text and images to be printed are made into a printing plate, which is then mounted on the printing press. Then, ink is applied manually or by the printing press to the areas on the printing plate containing the text and images. The ink is then transferred directly or indirectly to paper or other printing substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics), thereby reproducing a printed product identical to the printing plate.

[0003] The ink circulation device of the gravure printing machine uses a pump to transport ink from the ink storage tank to the printing unit. After the excess ink is scraped off by the doctor blade, the unused ink is returned to the filter for reuse, which can maintain the stability of ink viscosity and reduce waste, ensuring a continuous and efficient printing process.

[0004] When a gravure printing machine prints on a workpiece, some dust and impurities on the workpiece will fall into the ink, causing damage to the recycling components during recycling and reducing the recycling effect during long-term operation. Summary of the Invention

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0025] Referring to Figures 1 to 5, a gravure printing machine ink circulation device of this utility model includes a frame 1. An impression roller 11 and a printing roller 12 are sequentially arranged in the middle of the frame 1. An ink roller 13 is fixedly connected to the inner wall of the frame 1. A pneumatic diaphragm pump 14 is fixedly connected to the outer wall of the frame 1. An ink outlet 16 is connected to the middle of the pneumatic diaphragm pump 14. The ink outlet 16 is through-hole arranged on the frame 1. An ink tray 15 is fixedly connected inside the frame 1. The ink tray 15 is located below the ink outlet 16. The end of the ink tray 15... A recycling pipe 17 is connected to the main body; a pair of filter pipes 18 are installed at the end of the recycling pipe 17; multiple connection holes 19 are opened on the surface of the filter pipes 18; a filter screen 101 is installed inside the connection hole 19; the filter screen 101 and the filter pipes 18 are connected by a mounting assembly 103; an ink tank 104 is installed below the filter pipes 18; a circulation pipe 105 is connected to the top of the ink tank 104; the filter pipes 18 and the circulation pipe 105 are connected; a connecting pipe is connected to the side wall of the ink tank 104. Pipeline 106; the connecting pipe 106 and the pneumatic diaphragm pump 14 are connected by a pipe; during operation, the pneumatic diaphragm pump 14 is started first, and then the ink inside the connecting pipe 106 is drawn out through the pipe and enters the ink tray 15 through the ink outlet 16. When excess ink is generated, it moves to the filter pipe 18 through the recovery pipe 17. After entering the filter pipe 18, the ink is filtered by the filter screen 101. When the ink passes through the filter screen 101, impurities move to the surrounding area and leave the center of the filter screen 101. Then the ink enters the ink tank 104 through the circulation pipe 105 for circulation. After long-term use, the bolts inside the connecting hole 19 can be removed and the filter pipe 18 can be separated. Then, the filter screen 101 can be disassembled through the installation component 103 and the inside can be cleaned. By adding the filter screen 101, the ink can be filtered during circulation. At the same time, after long-term filtration, the filter pipe 18 can be disassembled to clean the impurities inside the filter pipe 18, thereby performing daily maintenance and extending its service life.

[0026] Referring to Figures 3 and 4, the mounting assembly 103 includes a pair of cylinders 2; the cylinders 2 and the filter screen 101 are fixedly connected; a rod 21 is fixedly connected to the middle of the filter screen 101 at the other end; the cylinders 2 and the rod 21 are correspondingly arranged and slidably engaged; a groove 22 is provided inside the filter pipe 18; the filter screen 101 is slidably engaged in the groove 22; during operation, when it is necessary to disassemble the filter screen 101, the filter pipe 18 is first separated, and after the filter pipe 18 is separated, the cylinders 2 and the rod 21 are then separated. When the separation is complete, the filter screen 101 will slide out of the filter pipe 18, at which point the internal parts can be cleaned. During installation, the cylinder 2 and the insert rod 21 are connected first. Then, the filter screen 101 is placed into the end of the groove 22 inside one of the filter pipes 18 and fixed. Then, the pair of filter pipes 18 are merged. After merging, the filter screen 101 will be at the end of the groove 22, thus being fixed by limiting the range of motion on both sides. By disassembling the filter screen 101, the space for movement can be increased during cleaning, thereby speeding up the cleaning of the inside of the filter pipe 18. At the same time, after the cylinder 2 and the insert rod 21 are connected, the pair of filter screens 101 will be merged. Thus, during filtration, the mutual abutment of the cylinder 2 and the insert rod 21 increases its own stability.

[0027] Referring to Figures 3 and 4, a sealing gasket 3 is fixedly connected to the inner wall of the filter pipe 18; multiple sealing gaskets 3 are provided on the filter pipe 18; during operation, when a pair of filter pipes 18 and recovery pipe 17 are connected to the circulation pipe 105, the sealing gasket 3 will be located between them, so that as they gradually merge and approach, the sealing gasket 3 will be squeezed. When squeezed, the sealing gasket 3 will be continuously squeezed. When the sealing gasket 3 is squeezed, it will deform, thereby increasing the friction between them through deformation; by adding sealing gaskets 3, the gaps can be filled by the deformation of the sealing gasket 3 when the filter pipes 18 are merged, thereby increasing the seal when they are merged.

[0028] Referring to Figures 3 and 4, a heating rod 4 is fixedly connected to the inner wall of the ink tank 104; multiple heating rods 4 are arranged on the ink tank 104; during operation, when the ink is placed inside the ink tank 104, multiple heating rods 4 can be activated to appropriately heat the ink inside the ink tank 104, thereby reducing ink adhesion to the pipeline during ink transfer; by adding heating rods 4, the ink can be heated when it is inside the ink tank 104, thereby increasing the viscosity inside the ink and thus increasing the smoothness of its movement in the pipeline.

[0029] Referring to Figure 5, a pair of slots 5 are provided in the middle of the filter pipe 18; a pair of insert plates 51 are fixedly connected to the middle of the filter pipe 18 at the other end; the slots 5 and the insert plates 51 are correspondingly arranged and slidably engaged; during operation, when the filter pipes 18 are merged, the slots 5 are aligned with the insert plates 51 so that the insert plates 51 enter the slots 5, thereby increasing the middle contact of the filter pipes 18 through the slots 5 and the insert plates 51 during merging; by adding the slots 5 and the insert plates 51, the middle contact can be increased after the filter pipes 18 are merged, thereby increasing the stability of the merged filter pipes 18 through the middle contact.

[0030] Referring to Figure 5, a foot 6 is fixedly attached to the bottom of the ink tank 104; multiple feet 6 are provided on the ink tank 104; during operation, when the ink tank 104 is placed, the foot 6 will first contact the ground. After contact, the foot 6 will be squeezed by the weight inside the ink tank 104, making it stick tightly to the ground. After sticking tightly, the friction between the ink tank 104 and the ground will be increased, thereby increasing stability; by adding feet 6, the frictional resistance can be increased after the ink tank 104 is placed, thereby reducing movement after placement.

[0031] Referring to Figures 3 and 4, the end of the filter screen 101 is set with an angled surface; by setting the end of the filter screen 101 with an angled surface, after the ink comes into contact with the filter screen 101, the impurities and debris can be guided to move to both sides, thereby reducing the time spent in the middle.

[0032] Referring to Figures 3 and 4, the sealing gasket 3 is arc-shaped. By making the sealing gasket 3 arc-shaped, it can fit more closely to the inner wall of the filter pipe 18 when the filter pipes 18 are joined, thereby reducing the gap when the filter pipes 18 are joined.

[0033] Working principle: First, the pneumatic diaphragm pump 14 is started, and then the ink inside the connecting pipe 106 is drawn out through the pipe and enters the ink tray 15 through the ink outlet 16. When excess ink is generated, it moves to the filter pipe 18 through the recovery pipe 17. After entering the filter pipe 18, the ink is filtered by the filter screen 101. When the ink passes through the filter screen 101, impurities move to the surrounding area and leave the center of the filter screen 101. Then, the ink enters the ink tank 104 through the circulation pipe 105 for circulation. After long-term use, the connecting hole 1 can be... 9. Remove the internal bolts and then separate the filter pipe 18. Then, disassemble the filter screen 101 using the installation assembly 103 and clean the interior. When disassembling the filter screen 101, first separate the filter pipe 18. After separating the filter pipe 18, separate the cylinder 2 and the insert rod 21. When separation is complete, the filter screen 101 will slide out of the filter pipe 18, at which point the interior can be cleaned. During installation, first connect the cylinder 2 and the insert rod 21, then place the filter screen 101 into the end of the groove 22 inside one of the filter pipes 18 and secure it. Then… Then, the pair of filter pipes 18 can be merged. After merging, the filter screen 101 will be at the end of the slide 22, thus fixing it by limiting the range of motion on both sides. When connecting the pair of filter pipes 18 and the recovery pipe 17 to the circulation pipe 105, the sealing gasket 3 will be located between them, so that it will be squeezed as they gradually merge and approach each other. When squeezed, the sealing gasket 3 will be continuously squeezed and deformed, thereby increasing the friction between them. When the ink is placed inside the ink tank 104, multiple heating rods 4 can be activated to heat the ink. The ink inside the ink tank 104 is appropriately heated to reduce ink adhesion to the pipes during ink transfer. When the filter pipes 18 are merged, the slot 5 is aligned with the insert plate 51 so that the insert plate 51 enters the slot 5, increasing the contact between the middle of the filter pipes 18 during merging. When the ink tank 104 is placed, the pad 6 will first contact the ground. After contact, the pad 6 will be squeezed by the weight inside the ink tank 104, making it stick to the ground. After sticking, the friction between the ink tank 104 and the ground will be increased, thereby increasing stability.

[0034] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
