[0002] In order to prevent ink waste during the printing process, an ink recovery device is required. Existing ink recovery devices usually use a filter to filter out impurities in the ink. The filter is very likely to be clogged, reducing the ink recovery efficiency of the ink recovery device.

[0003] In the related art, a search found a Chinese patent document (authorization announcement number CN211518887U) for a printing ink recovery device, comprising a housing, ink cartridges fixedly connected to the left and right inner walls of the housing via connecting rods, a filter tank box movably connected to the bottom surface of the housing, a filter tank box movably plugged into the filter tank, a first ink tube fixedly connected to the right side of the housing, the right end of the first ink tube fixedly connected to the filter box and extending into the interior thereof, a first pump disposed in the first ink tube, a second ink tube fixedly connected to the right side of the filter box, one end of the second ink tube fixedly connected to the ink cartridge and extending into the interior thereof, a second pump disposed in the second ink tube near the end of the filter box, and a third pump disposed in the second ink tube and above the second pump. This printing ink recovery device collects ink discarded by the printing device through the ink cartridge, filters it through the filter tank, and then filters it through the filter box for reuse. However, this device does not take into account the fact that the filter screen is very prone to clogging, which reduces the ink recovery efficiency of the device. Utility Model Content

[0004] The purpose of the utility model is to provide a printing ink recovery device to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a printing ink recovery device, comprising:

[0006] A recycling box for recycling printing ink, wherein the inner wall of the recycling box is fixedly connected to a filter frame, and the inner wall of the filter frame is fixedly connected to a filter screen for filtering printing ink;

[0007] The cleaning component includes a fixed plate and a brush plate. The moving parts of the linear motor are welded on both end surfaces of the fixed plate. The two linear motors are installed on the inner wall of the recycling box. The top two ends of the fixed plate are embedded and fixedly connected with an internal hollow telescopic outer rod. The inner cavity of the telescopic outer rod is slidably connected with a moving block. The top surface of the moving block is welded with a spring. The top surface of the spring is welded to the telescopic outer rod. The bottom surface of the moving block is welded with a telescopic inner rod. The bottom surfaces of the two telescopic inner rods are welded to the brush plate. The bottom surface of the brush plate is fixedly connected with a brush for cleaning the filter.

[0008] Preferably, the bottom surface of the telescopic outer rod is embedded and slidably connected with the telescopic inner rod, and the top surface and side surface of the recycling box are respectively equipped with a feed port and a discharge port.

[0009] Preferably, squeeze boxes are provided on both sides of the filter frame, and adjacent sides of the two squeeze boxes are connected to the recovery box.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are:

[0016] The printing ink recovery device introduces ink recovered from printing processing into a feed port, so that the recovered ink flows into the recovery box, and the ink flowing into the recovery box is filtered through a filter screen to prevent the recovered ink from being mixed with impurities, which is inconvenient for secondary use of the ink. The filter screen is easily clogged by impurities mixed with the ink during use, which reduces the ink recovery efficiency of the recovery device. Two linear motors are provided to provide power, so that the moving part of the linear motor drives the fixed plate to move during movement, and the brush plate drives the brush to clean the debris on the surface of the filter screen during transmission, thereby improving the ink recovery efficiency of the recovery device. The provided spring provides elastic thrust to make the moving block move along the inner cavity of the telescopic outer rod. Under the connection action of the telescopic inner rod, the contact effect between the brush and the filter screen is enhanced during transmission.

[0017] The printing ink recovery device uses a brush that moves laterally to clean debris on the surface of the filter screen. Driven by the brush, the debris flows into the extrusion box and is then introduced into the top of the inclined plate. An electric push rod is provided to provide power so that the moving end of the electric push rod drives the extrusion plate to move vertically during movement, so that the extrusion plate squeezes the debris on the top of the inclined plate and the ink mixed in the debris is squeezed out, thereby preventing ink waste and improving the ink recovery effect of the recovery device. The inclined plate is provided to facilitate the flow of ink into the recovery box. The extrusion box fixes the moving path of the two limit rods, thereby enhancing the vertical movement stability of the extrusion plate. The box door is provided to facilitate the removal of debris on the top of the inclined plate, thereby improving the functional structural stability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0029] In order to solve the problem that the filter of the printing ink recovery device is easily clogged during use, which reduces the ink recovery efficiency of the device, please refer to Figures 1 to 5 The structure of the device body is as follows:

[0030] A recycling box 1 for recycling printing ink has a filter frame 4 fixedly connected to the inner wall of the recycling box 1, and a filter screen 5 for filtering printing ink is fixedly connected to the inner wall of the filter frame 4. A feed port 2 and a discharge port 3 are respectively installed on the top and side of the recycling box 1. The feed port 2 is provided to facilitate the introduction of ink recovered during the printing process into the recycling box 1, thereby realizing the recovery of ink during the printing process. The filter frame 4 provides support and fixing for the filter screen 5, so that the filter screen 5 filters the recovered ink, prevents the ink from being mixed with foreign matter, and provides conditions for the recycling and reuse of the ink.

[0031] The cleaning component 6 and the filter screen 5 are used to recover and filter the ink. During the process, the filter screen 5 is easily clogged by impurities mixed in the ink, which reduces the recovery efficiency of the ink recovery device. The cleaning component 6 is provided to clean the impurities accumulated and clogged on the top surface of the filter screen 5, thereby improving the recovery efficiency of the ink recovery device. The cleaning component 6 includes a fixed plate 7 and a brush plate 8. The moving parts of the linear motor 9 are welded to the two end surfaces of the fixed plate 7. The adjacent sides of the moving parts of the two linear motors 9 are welded to the fixed plate 7, so that the moving parts of the two linear motors 9 drive the fixed plate 7 to move in the lateral position during the synchronous movement. The two linear motors 9 are installed on the inner wall of the recovery box 1, and the fixed ends of the two linear motors 9 are detachably connected to the inner wall of the recovery box 1 by bolts.

[0032] The top ends of the fixed plate 7 are embedded and fixedly connected with the internal hollow telescopic outer rod 10. The top ends of the fixed plate 7 are provided with through grooves. The inner walls of the two through grooves of the fixed plate 7 are fixedly connected with the two telescopic outer rods 10. The inner cavity of the telescopic outer rod 10 is slidably connected with a moving block 11, so that the moving block 11 moves along the inner cavity of the telescopic outer rod 10. The top surface of the moving block 11 is welded with a spring 12, and the top surface of the spring 12 is welded to the telescopic outer rod 10. The bottom surface of the moving block 11 is welded with a telescopic inner rod 13. The bottom surfaces of the two telescopic inner rods 13 are welded to the brush plate 8. The bottom of the brush plate 8 A brush 14 for cleaning the filter 5 is fixedly connected to the surface. Under the power provided by the two linear motors 9, the brush plate 8 drives the brush 14 to clean the debris on the top surface of the filter 5 during the transmission process, thereby improving the recovery efficiency of the ink recovery device. The spring 12 is provided to provide elastic thrust to move the moving block 11 downward along the inner cavity of the telescopic outer rod 10. Under the connection action of the telescopic inner rod 13, the brush plate 8 drives the brush 14 downward, thereby strengthening the contact tightness between the brush 14 and the filter 5, thereby improving the cleaning effect of the top surface of the filter 5;

[0033] The bottom surface of the telescopic outer rod 10 is embedded in the telescopic inner rod 13 for sliding connection. Squeezing boxes 15 are provided on both sides of the filter frame 4. The adjacent sides of the two squeezing boxes 15 are connected to the recovery box 1. The inner bottom wall of the squeezing box 15 is flush with the top surface of the filter frame 4, so that the brush 14 pushes the impurities mixed in the ink into the squeezing box 15 during the lateral movement. An electric push rod 17 is embedded in the top surface of the squeezing box 15. A through groove is opened on the top surface of the squeezing box 15. The inner wall of the through groove of the squeezing box 15 is detachably connected to the fixed end of the electric push rod 17 by bolts.

[0034] The moving end of the electric push rod 17 is welded with an extrusion plate 18 for squeezing ink doped with impurities. The bottom surface of the extrusion plate 18 is provided with an inclined plate 19. The upper inclined surface of the inclined plate 19 is connected with the bottom wall of the extrusion box 15. At the same time, the side of the inclined plate 19 close to the filter frame 4 is flush with the outer wall of the extrusion box 15, so that the debris flowing into the extrusion box 15 is located on the top surface of the inclined plate 19. The set electric push rod 17 provides power to drive the extrusion plate 18 downward during the movement of the moving end of the electric push rod 17, so that the extrusion plate 18 squeezes the debris located on the top surface of the inclined plate 19. At the same time, the inclination of the extrusion plate 18 is consistent with the inclination of the inclined plate 19, so that the ink doped with the debris is squeezed out. Under the guiding effect of the inclined plate 19, the squeezed ink flows into the recovery box 1 for recycling, thereby preventing the waste of ink and enhancing the recovery effect of the recovery device on the ink. The side of the inclined plate 19 is welded to the extrusion box 15;

[0035] Limit rods 20 are welded to both ends of the top of the extrusion plate 18, and limit blocks 21 are welded to the top surface of the limit rods 20. The inner top wall of the extrusion box 15 is embedded and slidably connected with the two limit rods 20. Through holes are provided at both ends of the inner top wall of the extrusion box 15. The two inner walls of the two through holes of the extrusion box 15 are slidably connected with the two limit rods 20, thereby fixing the vertical movement path of the two limit rods 20 and enhancing the vertical movement stability of the extrusion plate 18 during transmission. A box door 16 is installed on the side of the extrusion box 15 to facilitate opening the box door 16 and cleaning the extruded debris in the extrusion box 15.

[0036] The linear motor 9 and the electric push rod 17 are both existing technologies. Their working principles, sizes and models are irrelevant to the functions of this application, so they are not described in detail. The control method of the present invention is controlled by a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0037] How it works

[0038] When using the printing ink recovery device, the user introduces the ink recovered during the printing process into the recovery box 1 through the feed port 2, so that the ink flowing into the recovery box 1 is filtered by the filter 5, and the two linear motors 9 are started, so that the moving part of the linear motor 9 drives the fixed plate 7 to move during the movement, and the brush plate 8 drives the brush 14 to clean the debris on the top surface of the filter 5 during the transmission process. The spring 12 provides elastic thrust to move the moving block 11 downward along the inner cavity of the telescopic outer rod 10, and then the telescopic inner rod 13 and the brush plate 8 move downward, thereby strengthening the contact tightness between the brush 14 and the filter 5.

[0039] Driven by the lateral movement of the brush 14, the debris flows into the top surface of the inclined plate 19 in the squeezing box 15, and the electric push rod 17 is started. During the movement of the moving end of the electric push rod 17, the squeezing plate 18 is driven downward, so that the squeezing plate 18 squeezes the debris on the top surface of the inclined plate 19, so that the ink mixed in the debris is separated. Under the guiding effect of the inclined plate 19, the ink flows into the recovery box 1 for recovery. During the vertical movement of the squeezing plate 18, the two limit rods 20 are driven to move vertically along the through hole of the squeezing box 15, so that the squeezing plate 18 moves vertically and smoothly.
