Description
Technical Field
[0001] The utility model relates to the technical field of ink grinding, and more specifically to a grinding machine for ink processing. Background Art
[0002] Ink is an important material used in printing. It displays patterns and texts on substrates through printing or spraying. The 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. In the processing of ink, grinding is an important step. It needs to be ground with a grinder. The equipment currently used for grinding ink is mainly a three-roll grinder. The three-roll grinder mainly grinds the ink by passing through the three-axis rollers on it.
[0003] When using the existing ink processing grinder, ink is usually added to the hopper, and then falls directly into the space between the two groups of rollers on the rear side of the three-roller grinder through the bottom of the hopper. This results in the ink falling into a fixed position between the two groups of rollers, making it difficult to evenly disperse the ink between the two rollers, which can easily lead to a lack of ink in some areas between the two groups of rollers. This causes the area lacking ink to do useless work during the roller rotation and grinding process, resulting in waste and reducing the performance of the device. In view of this, we propose an ink processing grinder. Utility Model Content
[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a grinding machine for ink processing to solve the technical problem that when the current grinding machine for ink processing is used, part of the roller area is prone to doing useless work.
[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a grinding machine for ink processing, comprising a three-roll grinding machine, wherein a hopper is arranged at the front side of the top of the three-roll grinding machine through a bracket, and a material guide structure is arranged at the discharge port at the bottom of the hopper, wherein the material guide structure comprises a guide box and a uniform injection structure, wherein the guide box is arranged on the hopper, and the uniform injection structure is arranged obliquely on one side of the guide box;
[0006] A rectangular limiting cover is arranged at the bottom port of the uniform injection structure, and the rectangular limiting cover is open toward one side of the uniform injection structure, and a discharge port is opened at the bottom of the rectangular limiting cover.
[0007] When the ink in the hopper of the utility model is discharged from the bottom port, the ink enters the uniform injection structure of the material guide structure, and then the uniform injection structure can uniformly discharge the ink into between the two groups of rollers on the rear side of the three-roller grinder, thereby avoiding the situation that a partial area between the two groups of rollers on the rear side of the three-roller grinder 1 lacks ink, causing the three-roller grinder to do useless work, and solves the technical problem that when the current grinder for ink processing is used, some areas of its rollers are prone to do useless work, and when the ink is discharged from the bottom port of the uniform injection structure, the rectangular limit cover can block and limit the ink, and then the ink will be directly discharged vertically from the discharge port at the bottom of the rectangular limit cover, thereby changing the flow direction of the ink, making the ink fall vertically between the two rollers of the three-roller grinder, and no ink will leak out, further ensuring the stability of the ink falling between the two rollers of the three-roller grinder.
[0008] Preferably, the uniform injection structure comprises a fan-shaped box and a dividing plate, the top port of the fan-shaped box is connected to the guide box, and a plurality of groups of fan-shaped boxes are arranged inside the fan-shaped box.
[0009] Preferably, the fan-shaped boxes are distributed in a fan shape, and several groups of material channels are formed inside the uniform injection structure through the fan-shaped boxes. The extent of the bottom port of the fan-shaped box matches the length of the roller shaft in the three-roll grinder, and the rectangular limit cover is located above the two roller shafts in the three-roll grinder.
[0010] Preferably, reinforcement rods are arranged at both ends of the top of the rectangular limiting cover, and the top ends of the reinforcement rods are connected and fixed to the top edge of the front side of the hopper.
[0011] Preferably, a discharge structure is arranged on the guide box, and the discharge structure includes a mounting shaft, and the mounting shaft is rotatably arranged inside the guide box through a bearing, and two groups of symmetrical discharge paddles are arranged on the mounting shaft. A motor is symmetrically arranged on one side of the guide box with the mounting shaft, and the rotating shaft at the output end of the motor is connected to the corresponding end of the mounting shaft.
[0012] Preferably, the combined width of the mounting shaft and the two sets of discharge blades matches the width of the guide box, and the length of the mounting shaft and the discharge blades matches the length of the guide box.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The utility model designs a material guide structure. When the ink in the hopper is discharged from the bottom port, the ink enters the fan-shaped box of the material guide structure, and then a plurality of material channels are formed inside the fan-shaped box through a material dividing plate. Then the ink flows in the fan-shaped box through the material channels, and its flow is in a fan-shaped diffusion form, and then it is discharged from the bottom port of the fan-shaped box, so that the ink can be evenly discharged into the space between the two groups of rollers on the rear side of the three-roller grinder, thereby avoiding the situation that the part of the area between the two groups of rollers on the rear side of the three-roller grinder lacks ink, causing the part of the roller to do useless work, and solving the technical problem that when the current grinder for ink processing is used, the part of the roller is prone to do useless work. Therefore, the utility model has a faster grinding efficiency for ink.

[0023] Specifically, the uniform injection structure 5 includes a fan-shaped box 501 and a dividing plate 502, the top port of the fan-shaped box 501 is connected to the guide box 4, and several groups of fan-shaped boxes 501 are arranged inside the fan-shaped box 501; the fan-shaped boxes 501 are distributed in a fan shape, and several groups of material channels are formed inside the uniform injection structure 5 through the fan-shaped boxes 501. The extent of the bottom port of the fan-shaped box 501 matches the length of the roller shaft in the three-roll grinder 1, and the rectangular limit cover 503 is located above the two roller shafts in the three-roll grinder 1. The ink flows in the fan-shaped box 501 through the material channel, and its flow is in a fan-shaped distribution form, and then discharged from the bottom port of the fan-shaped box 501, so that the ink can be evenly discharged between the two groups of roller shafts on the rear side of the three-roll grinder 1.
