Description

Technical Field

[0001] This utility model relates to the field of ink manufacturing technology, specifically to a color paste filtration device for ink manufacturing. Background Technology

[0002] In the ink manufacturing process, the filtration of pigment paste is a crucial step in ensuring ink quality. Existing technologies typically use filter screens to physically separate impurities in the ink and clean the filter residue through squeezing or scraping. However, in practical applications, some fine impurities easily clog the filter screen pores, leading to decreased filtration efficiency and even affecting ink flowability. To address this issue, existing technologies have proposed various filter residue cleaning mechanisms, such as scraping impurities from the filter screen surface with a scraper or using pneumatic or hydraulic pressure to assist filtration. However, these methods often fail to completely remove impurities embedded in the mesh, and prolonged use can still lead to filter screen clogging, requiring frequent shutdowns for cleaning and reducing production efficiency.

[0003] In the prior art, such as the filter device for ink pigments disclosed in the Chinese authorized patent (publication number: CN202321823091.X), a cylinder drives an extrusion plate to accelerate filtration and a scraper is used in conjunction with a filter residue baffle to clean impurities on the surface of the filter screen. However, when this device is in use, the scraper can only remove impurities on the surface of the filter screen, while particles embedded in the mesh will be further compressed and difficult to remove completely. Long-term accumulation will lead to a decrease in the permeability of the filter screen. Relying on the unidirectional push of the scraper, it is impossible to actively release the blockage in the mesh, which increases maintenance costs and affects the continuous working capacity of the filtration device. Utility Model Content

[0004] The purpose of this invention is to provide a color paste filtering device for ink manufacturing, which solves the problem of difficult-to-remove impurities from the filter mesh by ejecting impurities from the mesh through a top-out part.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a color paste filtration device for ink manufacturing, including a filter box and a top outlet. A filter screen is installed inside the filter box. The top outlet has a rectangular frame, horizontal bars and pins. Horizontal bars are arranged in an array inside the rectangular frame. Each horizontal bar is provided with a row of pins. An L-shaped plate is installed on the outer surface of the rectangular frame. An electric push rod is provided on the outer surface of the filter box. The output end of the electric push rod is connected to the top plate of the L-shaped plate.

[0007] Furthermore, each ejector pin has a chamfered top.

[0008] Furthermore, there is a discharge port between two adjacent horizontal bars, and a row of guide grooves is opened on each horizontal bar. The guide grooves are inclined structures and are located between two adjacent ejector pins.

[0009] Furthermore, a sliding groove is provided inside the side plate of the filter box, and the L-shaped plate slides within the sliding groove.

[0010] Furthermore, a reserved groove is provided on the top of the side plate of the filter box. The reserved groove is connected to the slide groove. A stop block is installed on the top of the reserved groove, and the top plate of the L-shaped plate fits into the reserved groove.

[0011] Furthermore, the filter box has a feed inlet and a discharge outlet at the bottom.

[0012] This utility model has the following beneficial effects:

[0013] This invention uses a top-out part to push out impurities from the filter screen mesh. Before the scraper scrapes the filter screen, the rectangular frame moves upward so that several pins push out the impurities clogging the filter screen mesh, clearing the impurities from the mesh and preventing the accumulation and further clogging of impurities in the mesh. This ensures the permeability of the filter screen and improves the filtration efficiency. In addition, the baffle blocks limit the maximum height of the pins, preventing the scraper from squeezing impurities back into the mesh when scraping. This reduces production costs and maintenance difficulty, and improves production efficiency.

[0014] This invention guides the ink through a guide groove and a discharge port. The inclined surface and chamfer of the guide groove, combined with the discharge port between the horizontal bars, allow the ink to flow smoothly, preventing it from accumulating around the ejector pin and above the horizontal bars, thus avoiding obstruction of ink flow and residue. By guiding the ink downwards, waste and cleaning difficulty are reduced, and filtration efficiency is improved.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a color paste filtering device for ink manufacturing, including a filter box 1 and a top outlet 3. The filter box 1 has an inlet 101 and an outlet 102 at its bottom. A filter screen 2 is installed inside the filter box 1. A sliding groove 103 is provided in the side plate of the filter box 1, and an L-shaped plate 307 is slidably fitted within the sliding groove 103. A reserved groove 104 is provided at the top of the side plate of the filter box 1. The bottom of the reserved groove 104 is higher than the inlet 101 to prevent ink from flowing out of the reserved groove 104. The reserved groove 104 is connected to the sliding groove 103. A stop block 6 is installed at the top of the reserved groove 104. When the top plate of the L-shaped plate 307 contacts the bottom surface of the stop block 6, the top tip of the ejector pin 303 is located within the mesh of the filter screen 2, preventing the scraper (the scraper is prior art and will not be discussed here) from being scraped. (To avoid excessive detail) When pushed, impurities re-enter the mesh and to prevent obstruction of the scraper's movement, the top plate of the L-shaped plate 307 fits into the reserved groove 104. The ejector part 3 has a rectangular frame 301, horizontal bars 302, and ejector pins 303. Horizontal bars 302 are arrayed inside the rectangular frame 301, and each horizontal bar 302 is provided with a row of ejector pins 303. The L-shaped plate 307 is installed on the outer surface of the rectangular frame 301. The L-shaped plate 307 consists of a top plate and a vertical plate. The top plate is installed on the top of the vertical plate, and the bottom of the vertical plate is connected to the outer surface of the rectangular frame 301. The top plate fits into the reserved groove 104. An electric push rod 5 is provided on the outer surface of the filter box 1. A rectangular block 4 is installed on the outer surface of the filter box 1. The bottom of the electric push rod 5 is installed on the top surface of the rectangular block 4, and the output end of the electric push rod 5 is connected to the top plate of the L-shaped plate 307.

[0023] After the untreated ink added from the feed inlet 101 is filtered through the filter screen 2, before the impurities on the filter screen 2 are scraped off by the scraper, the electric push rod 5 is activated so that the output end of the electric push rod 5 pushes the L-shaped plate 307 upward, causing the top plate of the L-shaped plate 307 to move along the reserved groove 104. At this time, the top plate of the L-shaped plate 307 drives the vertical plate to move upward along the slide groove 103, thereby driving the rectangular frame 301 to lift the ejector pin 303 until the top plate of the L-shaped plate 307 contacts the bottom surface of the stop block 6, limiting the height of the ejector pin 303. At this time, the ejector pin 303 pushes out the impurities in the mesh of the filter screen 2, and the top of the ejector pin 303 is in the mesh of the horizontal bar 302, preventing the impurities from being squeezed into the mesh of the filter screen 2 when the scraper removes the impurities.

[0024] Each ejector pin 303 has a chamfer 304 on its top. The chamfer 304 reduces obstruction and wear on the mesh when the ejector pin 303 enters the mesh of the filter screen 2. It also helps guide the ink through the guide groove 305 when the ink is discharged, making it easier for the ink to drain.

[0025] Between two adjacent horizontal bars 302, there is a discharge port 306. Each horizontal bar 302 has a row of guide grooves 305. The guide grooves 305 have an inclined structure and are located between two adjacent ejector pins 303. After the ink is filtered by the filter screen 2, it flows to the bottom of the filter screen 2. At this time, the ink is discharged through the discharge port 306 between the adjacent horizontal bars 302. The ink dripping onto the horizontal bars 302 and ejector pins 303 is guided to the bottom by the chamfer 304. With the help of the inclined structure guide grooves 305 on the horizontal bars 302, the ink is guided to the discharge ports 306 on both sides and discharged from the discharge port 102, thereby avoiding obstruction of ink discharge.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
