Abstract
Description
Technical Field
[0001] This utility model relates to the field of ink recycling technology, specifically to an ink recycling device with a filtration function. Background Technology
[0002] Ink is an essential material used in printing, which transfers patterns and text onto a substrate through printing or inkjet printing. Ink consists of main and auxiliary components that are uniformly mixed and repeatedly rolled to form a viscous, colloidal fluid. During ink recycling, impurities can be separated through filtration, improving the quality of ink recovery.
[0003] Currently, a Chinese patent discloses an ink filtration and recovery device (authorization announcement number CN213313587U). Through a collection box, a limiting ring, a filter barrel, a first oil outlet pipe, a lower filter tank, an upper filter tank, a filter screen, and a second oil outlet pipe, it can achieve a good filtration effect, solving the problem of poor filtration effect of general ink recovery devices. This allows the recovery device to filter impurities in the ink, thereby reducing the difficulty of subsequent processing and providing convenience for workers.
[0004] According to the above reference materials, in the above device, the ink enters the upper filter tank through the second oil outlet pipe and undergoes the first filtration through the filter screen. After being filtered by the filter screen, the ink enters the filter barrel through the first oil outlet pipe and the lower filter tank, where it undergoes the second filtration. The filtered ink is then collected through the collection box. However, when this device uses a filter screen and filter barrel to filter the ink, impurities after the ink filtration are prone to clogging the filter device. Frequent disassembly and cleaning of the filter device affects the ink recovery efficiency, making it inconvenient to effectively filter the ink and reducing the effectiveness of the device.
[0005] Based on this, the present invention designs an ink recovery device with filtration function to solve the above problems. Utility Model Content
[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an ink recovery device with filtration function.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] An ink recovery device with a filtration function includes a filter box with a cover installed on the top of the filter box, and a filtration mechanism disposed on the inner wall of the filter box. Two filter plates are slidably connected to the inner wall of the filter box, and a rotating rod is rotatably connected to the inner wall of the filter plate. Cleaning plates are fixedly connected to both sides of the rotating rod, and the bottom end of the cleaning plate is in contact with the inner wall of the filter plate.
[0009] Furthermore, the filtration mechanism also includes a connecting rod rotatably connected to the middle of the inner wall of the filter box. A fixing plate is fixedly connected to the middle of the inner wall of the filter box. The connecting rod is rotatably connected to the inner wall of the fixing plate. The grooves at both ends of the connecting rod are respectively engaged with one end of the two rotating rods.
[0010] Furthermore, a drive rod is rotatably connected to the bottom end of the box cover, and a groove at one end of the drive rod engages with the other end of one of the rotating rods.
[0011] Furthermore, a motor is installed at the top of the box cover, and the output shaft at one end of the motor is fixedly connected to the top of the drive rod.
[0012] Furthermore, a sealing block is installed on one side of the filter plate, and the sealing block is fitted into the inner wall of the filter box.
[0013] Furthermore, two fixing bolts are rotatably connected to one side of the filter plate, with one end of each fixing bolt penetrating the filter plate and threadedly connected to the filter box.
[0014] Furthermore, the front end of the filter box is provided with two observation slots.
[0015] Furthermore, the bottom of the filter box is connected to a discharge pipe, one end of which extends to the outside of the filter box.
[0016] Beneficial effects
[0017] 1. The two filter plates inside the filter box can perform coarse and fine filtration of ink respectively, improving the filtration effect of the recovery device. The two rotating rods are engaged with the grooves at both ends of the connecting rod. The top of one rotating rod is engaged with the groove at the bottom of the drive rod. The grooves on the connecting rod and the drive rod are straight grooves. The motor can drive the cleaning plates on both sides of the two rotating rods to rotate and clean the impurities filtered on the filter plates, preventing the filter plates from clogging and affecting the filtration efficiency of the ink. The sealing block between the filter plate and the filter box can prevent ink leakage. Two fixing bolts can fix the filter plates. The filter plates can be disassembled for replacement and cleaning, which can prevent impurities in the ink from clogging the filter plates and improve the filtration effect of the recovery device.
[0018] 2. When filtering and recovering ink, the two observation slots at the front of the filter box are transparent, allowing observation of the ink filtration process. When installing or removing the filter plate, the connection positions of the rotating rod, connecting rod, and drive rod can be adjusted through the observation slots to align the slots of the connecting rod and drive rod to one side, facilitating the installation and removal of the filter plate. This also allows for cleaning and replacement of the filter plate, improving the filtration effect of the recovery device. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0027] The present invention will be further described below with reference to the embodiments.
[0028] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4An ink recovery device with filtration function includes a filter box 1, a box cover 2 installed on the top of the filter box 1, and a filtration mechanism 3. The filtration mechanism 3 is disposed on the inner wall of the filter box 1. Two filter plates 301 are slidably connected to the inner wall of the filter box 1. A rotating rod 302 is rotatably connected to the inner wall of the filter plate 301. Cleaning plates 303 are fixedly connected to both sides of the rotating rod 302. The bottom end of the cleaning plate 303 is in contact with the inner wall of the filter plate 301.
[0029] The ink is transported through a pipe at the top of the cover 2 to one of the filter plates 301. One filter plate 301 can perform coarse filtration of the ink. The coarsely filtered ink falls to the other filter plate 301 for fine filtration. While the filter plate 301 is filtering the ink, two rotating rods 302 are engaged together through a connecting rod 304. One of the rotating rods 302 is engaged with a drive rod 306. The motor 307 is started by the PLC control panel at the front of the filter box 1 to rotate at a constant speed. The motor 307 drives the cleaning plates 303 on both sides of the rotating rod 302 through the drive rod 306 to clean the impurities on the filter plate 301, thereby improving the filtration effect of the recovery device.
[0030] In some embodiments, such as Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the filter mechanism 3 further includes a connecting rod 304 rotatably connected to the middle of the inner wall of the filter box 1. A fixing plate 305 is fixedly connected to the middle of the inner wall of the filter box 1. The connecting rod 304 is rotatably connected to the inner wall of the fixing plate 305. The grooves at both ends of the connecting rod 304 are respectively engaged with one end of the two rotating rods 302.
[0031] When the two rotating rods 302 are driven to rotate, the connecting rod 304 engages with one end of the rotating rod 302 through the slots at both ends. When the driving rod 306 drives one of the rotating rods 302 to rotate, one of the rotating rods 302 drives the other rotating rod 302 to rotate through the connecting rod 304, which can prevent the filter plate 301 from becoming clogged during use.
[0032] In this embodiment of the utility model, a drive rod 306 is rotatably connected to the bottom end of the box cover 2, and the groove at one end of the drive rod 306 is engaged with the other end of one of the rotating rods 302.
[0033] The drive rod 306 engages with the top of one of the rotating rods 302 through a slot at the bottom, allowing it to rotate. One of the rotating rods 302 drives the other rotating rod 302 to rotate through a connecting rod 304, which in turn drives the cleaning plates 303 on both sides of the two rotating rods 302 to clean the impurities on the filter plate 301.
[0034] In this embodiment of the utility model, a motor 307 is installed at the top of the box cover 2, and the output shaft at one end of the motor 307 is fixedly connected to the top of the drive rod 306.
[0035] The motor 307 can be driven to run by manually operating the PLC control panel, which in turn drives the drive rod 306 to rotate at a constant speed. The drive rod 306 and the connecting rod 304 then drive the two rotating rods 302 to rotate.
[0036] In this embodiment of the present invention, a sealing block 308 is installed on one side of the filter plate 301, and the sealing block 308 is fitted into the inner wall of the filter box 1.
[0037] The sealing block 308 on one side of the filter plate 301 fits against the inner wall of the filter box 1, which can prevent ink leakage during ink recycling.
[0038] In this embodiment of the utility model, two fixing bolts 309 are rotatably connected to one side of the filter plate 301. One end of the fixing bolt 309 passes through the filter plate 301 and is threadedly connected to the filter box 1.
[0039] Manually rotate the two fixing bolts 309, which are threadedly connected to the filter box 1, to move them to one side to release the restriction on the filter plate 301. The filter plate 301 can then be removed from the filter box 1, and impurities on the filter plate 301 can be cleaned to prevent them from clogging the filter plate 301.
[0040] In some embodiments, such as Figure 2 and Figure 4 As shown, in a preferred embodiment of the present invention, the front end of the filter box 1 is provided with two observation slots 310.
[0041] When installing or removing the filter plate 301, the openings of the grooves on the connecting rod 304 and the drive rod 306 can be rotated to one side and aligned by looking through the observation groove 310. The rotating rod 302 can then be removed from the connecting rod 304 and the drive rod 306, making it convenient to disassemble and clean the filter plate 301.
[0042] In this embodiment of the present invention, the bottom end of the filter box 1 is connected to a discharge pipe 311, and one end of the discharge pipe 311 extends through to the outside of the filter box 1.
[0043] After being filtered twice, the ink falls to the bottom of the filter box 1 and is discharged through the discharge pipe 311, allowing for further processing of the ink.
[0044] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
