Description

Technical Field

[0001] The utility model relates to the technical field of ink processing, in particular to a circulating grinding device for ink production. Background Art

[0002] Ink is an important material used in printing. It displays patterns and texts on substrates through printing or spraying. Ink includes main ingredients and auxiliary ingredients, which are evenly mixed and repeatedly rolled to form a viscous colloidal fluid. It is composed of binders (resins), pigments, fillers, additives and solvents. It is used for various printings such as books and periodicals, packaging and decoration, architectural decoration and electronic circuit boards. As social demand increases, the variety and output of inks have also expanded and grown accordingly.

[0003] The traditional ink grinding process is relatively simple. Generally, the ink is broken up and then directly filtered out. The quality of the ink produced is not good. In addition, the process only has a single arrow method for sending out after grinding. If the grinding is not sufficient, it needs to be re-loaded and ground again. The process is relatively cumbersome and inconvenient for manual operation.

[0004] Therefore, the utility model provides a circulating grinding device for ink production. Utility Model Content

[0005] The purpose of this utility model is to solve the above shortcomings in the prior art. In order to achieve the above purpose, this utility model adopts the following technical solutions:

[0007] The grinding barrel is provided with a feed channel on the outside and a filter plate on the inside. The filter plate is provided with a plurality of filter sieve holes. A rotating shaft is fixed downwardly to the middle of the filter plate. The rotating shaft extends toward the outside of the grinding barrel and is driven to rotate by an external first drive assembly.

[0008] The first drive assembly includes a first motor, the output end of the first motor is downwardly connected to a drive shaft, a first sprocket is sleeved on the bottom of the drive shaft, a second sprocket is sleeved on the bottom of the rotating shaft, and the first sprocket and the second sprocket are linked by a chain;

[0009] A second drive assembly is mounted on the top of the grinding barrel. The second drive assembly includes a second motor mounted on a support frame. The second motor is connected to a stirring shaft facing the interior of the grinding barrel. An annular mixing ring is welded to the lower end of the stirring shaft. Rolling grinding balls are also provided in the grinding barrel. After assembly, the grinding balls cooperate with the annular mixing ring to grind the ink.

[0010] Sampling points are respectively arranged at the junctions of the three-way pipe with the outflow pipe, the reflux pipe and the discharge pipe.

[0011] Preferably, the intersection of the rotating shaft and the bottom end of the grinding barrel is sealed by a sealing ring, and the intersection of the rotating shaft and the outer side of the grinding barrel is also sealed with a sealing ring. The outside of the grinding barrel is also connected to a limit bearing, and the rotating shaft is outer-connected in the limit bearing to achieve the effect of limited installation.

[0012] Preferably, the second motor is mounted on a support column, and the support column is arranged in a "7" shape at the upper end of the supporting frame.

[0013] Preferably, the drive shaft is vertically sleeved on the support plate, and the support plate is installed on the support frame to facilitate the limited installation of the support plate.

[0014] Preferably, the impurity filter box includes a wide feed opening that is sleeved with the guide tube, and the feed aperture of the wide feed opening is larger than the discharge aperture of the guide tube, so as to prevent the ink in the guide tube from overflowing and flowing out.

[0015] Preferably, the lower part of the feed wide mouth is fixedly connected to the buffer tube head, the filter tube in the impurity filter box is serpentine, the front end of the filter tube is provided with a first-level filter grid, and the rear end is provided with a second-level link grid. The grid aperture of the first-level filter grid is larger than the grid aperture of the second-level link grid, and the seafood is filtered step by step.

[0016] Preferably, there are more than two secondary linking grids in the filter tube. When the ink enters the secondary linking grid from the primary filter grid, the impurities are deposited at the bottom of the filter tube, making it easier for the impurities to settle in the transit tube.

[0017] Preferably, the outflow pipe is arranged at the upper end of the impurity filter box discharge, which is also to facilitate the precipitation of excess impurities below the filter pipe and reduce the amount of impurities and large particles in the outflowing ink.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. By setting grinding balls in the grinding barrel and matching the annular mixing ring in the second drive assembly, the ink is broken up, ground and precipitated at the same time. In addition to using grinding balls, the addition of the annular mixing ring can improve the thoroughness of stirring and enable it to be fully ground.

[0021] 2. By setting a filter plate at the bottom of the grinding barrel for screening and then using the impurity filter box for screening, the impurities and large particles contained in the ground ink can be greatly enhanced, achieving a multi-stage filtration effect, and ensuring that most of the ground ink can be directly used through the discharge pipe.

[0022] 3. By setting a rotating shaft at the bottom of the filter plate, the external first driving member can drive the filter plate to rotate, and at the same time promote the contact between the grinding balls on the filter plate and the annular mixing ring, and the contact between the grinding balls, so as to achieve effective grinding;

[0023] 4. By setting up sampling points around the three-way pipe, the quality of the ink can be judged through random inspections, and then a decision can be made whether to discharge the ink or re-grind it. This avoids the instability of one-time discharge and reduces the manual operation of transporting the ink back for grinding, making the overall operation smoother. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Working principle:

[0038] When the utility model is in use, ink is fed into the grinding barrel from the feed channel, and the second motor in the second drive assembly is used to drive the stirring shaft to rotate, thereby driving the annular mixing ring to rotate. The annular mixing ring and the grinding balls on the filter plate are in contact and cooperate with each other, and the grinding balls cooperate with each other to achieve ink grinding. Ink particles that meet the aperture of the filter plate flow downward due to gravity. At this time, the first motor of the first drive assembly drives the driving shaft, and the driving shaft drives the first sprocket below to rotate. A second sprocket is provided below the rotating shaft facing outward, and the first sprocket and the second sprocket are driven by a chain. Then the filter plate drives the grinding balls to move and achieve the filtering effect; through the guide pipe, the ink enters the impurity filter box, passes through the first-level filter grid and the second-level link grid in the impurity filter box, and is filtered step by step before being discharged through the outflow pipe and flows to the tee pipe. Since sampling points are respectively arranged at the junction of the tee pipe and the outflow pipe, the return pipe and the discharge pipe, before the ink is set to flow out, samples are first taken at the front end of the discharge pipe and the end of the outflow pipe. If the ground ink meets the specifications, the electric control valve on the discharge pipe is opened to discharge the ink. If it does not meet the specifications, it is pumped back from the return pipe through the liquid pump and flows into the grinding barrel for further processing.
