Description

Technical Field

[0001] The present invention relates to the field of ink production devices, and particularly to an ink proportioning device. Background Art

[0002] The water-based flexographic ink in printing ink is mainly composed of water-soluble resin, organic pigment, solvent and related additives through compound grinding and processing. The special ink used in flexographic printing presses is water-based ink. Its advantages are no pollution to the environment, no impact on human health, not easy to burn, good safety, stable ink performance, bright color, not corroding the plate, simple operation, low price, good post-printing adhesion, strong water resistance, rapid drying, and the printing speed can reach 150 - 200 m per minute; precisely due to the above characteristics, flexographic water-based ink is particularly suitable for the printing and use of packaging and decoration printing products such as food, medicine, and cosmetics that have strict requirements for sanitary conditions.

[0003] However, nowadays, the manufacturing of printing ink is to add various pigments to a blender in corresponding proportions for stirring. Patent application number: CN202020820085.9 discloses a stirring device for proportioning type ink production, including a box body. The four corners of the bottom surface of the box body are fixedly connected with support legs. The bottom of the inner cavity of the box body is circumferentially fixedly connected with a material collecting hopper. The bottom of the inner cavity of the box body is fixedly communicated with a discharge pipe. A discharge control valve is installed on the surface of the discharge pipe. The center of the top surface of the box body is fixedly connected with a double-shaft positive and negative rotation motor. The bottom of the rotating shaft of the double-shaft positive and negative rotation motor is connected with a stirring shaft through a coupling. The bottom of the stirring shaft penetrates to the bottom of the inner cavity of the box body. Stirring plates are fixedly connected to the bottom surfaces of both sides of the stirring shaft; when in use, raw materials are added into the storage box, and the double-shaft positive and negative rotation motor runs to drive the stirring shaft to rotate, so that the stirring frame and the stirring rod rotate up and down, and the raw materials of the ink are evenly mixed. However, for such an ink proportioning device, after the proportioning is completed, a certain amount of ink remains in the box body, affecting the next ink proportioning.

[0004] The present invention is studied and proposed in view of the deficiencies of the prior art. Summary of the Invention

[0005] The object of the present invention is to overcome the above-mentioned deficiencies of the prior art and provide an ink proportioning device.

[0006] The present invention can be realized through the following technical solutions:

[0007] The present invention discloses an ink proportioning device, which includes a limiting tube fixed on a frame. A top plate slidably connected to the limiting tube is arranged inside the limiting tube. A bottom plate slidably connected to the limiting tube is fixed below the top plate. An outlet groove is arranged on the bottom plate. A plurality of stirring shafts are also arranged on the bottom plate. Stirring blades are fixed on the stirring shafts. The stirring shafts are all driven to rotate by a stirring motor. A spray pipe surrounding the limiting tube is also fixed on the frame below the limiting tube. A plurality of nozzles are evenly fixed on the spray pipe. A water pump is connected to the spray pipe through a water inlet pipe. A plurality of feed pipes are fixed on the limiting tube. The feed pipes are all connected to corresponding pigment storage tanks. A fixing plate is also fixed on the frame above the limiting tube. A lifting motor is fixed on the fixing plate. A screw rod is fixed at the output end of the lifting motor. A threaded pipe is fixed on the top plate. The screw rod is threadedly connected to the threaded pipe. The limiting tube, the top plate and the bottom plate form a stirring cavity. The corresponding pigments are discharged into the stirring cavity in a certain amount according to the required ink to be configured. The pigments in the pigment storage tanks are pumped through the feed pipes and discharged into the stirring cavity. After the specified amount of pigments enter the stirring cavity, the solenoid valves on the feed pipes are closed. The stirring motor drives each stirring shaft to stir the inside of the stirring cavity. When the pigments are fully stirred, the lifting motor is started. The lifting motor drives the screw rod to rotate. Since the screw rod is threadedly connected to the threaded pipe, when the screw rod rotates, the threaded pipe moves in the direction of the screw rod, and the top plate and the bottom plate descend. When the outlet groove on the bottom plate reaches below the limiting tube, the ink is discharged through the outlet groove for collection. After the pigments are collected, the lifting motor is started again, and the top plate and the bottom plate continue to descend. And the cleaning agent is pumped through the water pump and sprayed through each nozzle. The top plate, the bottom plate, the stirring shafts and the stirring blades are rinsed through the nozzles to wash the pigments clean. And when the top plate descends, the inner wall of the limiting tube is scraped by the top plate to scrape the pigments on the inner wall of the limiting tube clean. And through the rinsing of the nozzles, the residual ink between the bottom plate and the top plate is rinsed clean. After being rinsed clean, the lifting motor drives the screw rod to rotate in the reverse direction, and the top plate and the top plate reach inside the limiting tube again for cyclic operation. This device can realize the configuration of ink in a certain proportion, and after the configuration is completed, the ink in the device is rinsed clean, which can effectively avoid the influence of ink residue on the next ink proportioning.

[0008] Preferably, sealing rings are also fixed on the top plate and the bottom plate. The sealing performance of the device is ensured through the sealing rings to prevent the ink from discharging from the gap between the bottom plate and the limiting tube during ink configuration.

[0009] Preferably, driven gears are fixed on the stirring shafts. A rotating shaft is fixed at the output end of the stirring motor. A driving gear is fixed on the rotating shaft. The driving gear meshes with each driven gear.

[0010] Preferably, a baffle is also fixed at the bottom of the bottom plate. The cleaning liquid is prevented from reaching the position of the stirring motor through the baffle.

[0011] Preferably, a plurality of positioning tubes are also fixed on the fixed plate, positioning rods are fixed at positions corresponding to the positioning tubes on the top plate, and the positioning rods are slidably connected with the positioning tubes. The smooth rising and falling of the top plate are realized through the cooperation of the positioning tubes and the positioning rods.

[0012] Preferably, ventilation holes penetrating the top plate are also provided on the top plate. The air pressure on both sides of the top plate is balanced through the ventilation holes to ensure that the pigment can enter the stirring cavity.

[0013] The present invention has the following advantages compared with the prior art:

[0014] This device can realize the preparation of ink in a certain proportion, and after the preparation is completed, the ink in the device is washed clean, which can effectively avoid the influence of ink residue on the next ink ratio. BRIEF DESCRIPTION OF THE DRAWINGS

On the bottom plate 3, there is a discharge groove 4. On the bottom plate 3, there are also multiple stirring shafts 6. Stirring blades 7 are fixed on the stirring shafts 6. The stirring shafts 6 are all driven to rotate by a stirring motor 8. On the frame below the limiting tube 1, there is also a spray pipe 20 fixed around the limiting tube 1. Multiple nozzles 21 are evenly fixed on the spray pipe 20. The spray pipe 20 is also connected to a water pump through a water inlet pipe 22. On the limiting tube 1, there are also multiple feed pipes 19 fixed. The feed pipes 19 are all connected to corresponding pigment storage tanks (not shown). On the frame above the limiting tube 1, there is also a fixing plate 15 fixed. On the fixing plate 15, there is a lifting motor 14 fixed. The output end of the lifting motor 14 is fixed with a screw rod 16. A threaded pipe 13 is fixed on the top plate 2. The screw rod 16 is threadedly connected to the threaded pipe 13. The limiting tube 1, the top plate 2 and the bottom plate 3 form a stirring cavity. The corresponding pigments for the ink to be configured according to requirements are discharged into the stirring cavity in a certain amount. After the pigments in the pigment storage tank are extracted by a pump, they are discharged into the stirring cavity through the feed pipes 19. After the specified amount of pigments enter the stirring cavity, the solenoid valves on the feed pipes 19 are closed. The stirring motor 8 is used to drive each stirring shaft 6 to stir the inside of the stirring cavity. When the pigments are fully stirred, the lifting motor 14 is started. The lifting motor 14 drives the screw rod 16 to rotate. Since the screw rod 16 is threadedly connected to the threaded pipe 13, when the screw rod 16 rotates, the threaded pipe 13 moves in the direction of the screw rod 16, and the top plate 2 and the bottom plate 3 descend. When the discharge groove 4 on the bottom plate 3 reaches below the limiting tube 1, the ink is discharged and collected through the discharge groove 4. After the pigments are collected, the lifting motor 14 is started again, and the top plate 2 and the bottom plate 3 continue to descend. And after the cleaning agent is extracted by the water pump, it is sprayed out through each nozzle 21. The top plate 2, the bottom plate 3, the stirring shafts 6 and the stirring blades 7 are rinsed through the nozzles 21 to wash the pigments clean. And when the top plate 2 descends, the inner wall of the limiting tube 1 is scraped by the top plate 2 to scrape the pigments on the inner wall of the limiting tube 1 clean. And through the rinsing of the nozzles 21, the residual ink between the bottom plate 3 and the top plate 2 is rinsed clean. After being rinsed clean, the lifting motor 14 drives the screw rod 16 to rotate in the reverse direction, and the top plate 2 and the top plate 2 reach inside the limiting tube 1 again for cyclic operation. This device can realize the proportioning of ink according to a certain ratio, and after the configuration is completed, the ink in the device is rinsed clean, which can effectively avoid the influence of ink residue on the next ink proportioning.

[0024] Wherein, sealing rings 5 are also fixed on the top plate 2 and the bottom plate 3. The sealing performance of the device is ensured through the sealing rings 5 to prevent the ink from discharging from the gap between the bottom plate 3 and the limiting tube 1 during ink configuration.

[0025] Wherein, driven gears 11 are fixed on the stirring shafts 6. The output end of the stirring motor 8 is fixed with a rotating shaft 9. A driving gear 10 is fixed on the rotating shaft 9. The driving gear 10 meshes with each driven gear 11.

[0026] Among them, a plurality of positioning tubes 17 are also fixed on the fixed plate 15, and positioning rods 18 are fixed at positions corresponding to the positioning tubes 17 on the top plate 2. The positioning rods 18 are slidably connected to the positioning tubes 17. The smooth rising and falling of the top plate 2 are realized through the cooperation of the positioning tubes 17 and the positioning rods 18.

[0027] Among them, ventilation holes 23 penetrating through the top plate 2 are also provided on the top plate 2. The air pressures on both sides of the top plate 2 are balanced through the ventilation holes 23 to ensure that the pigment can enter the stirring cavity.
