Description

Technical Field

[0001] This utility model belongs to the field of pigment grinding technology, and in particular relates to a high-efficiency grinding equipment for pigment production. Background Technology

[0002] Color pastes are made from different pigments through a rigorous processing technique involving surface treatment and coating. Based on the solvent used, color pastes are classified into oil-based, water-based, and water-oil hybrid color pastes. Oil-based color pastes use pure oil as a binder. Water-based color pastes are pigment-filler pastes dispersed in water with added surfactants. Because there are many types of paints, there are also many types of color pastes. To better disperse pigments in paints, a small amount of resin is often added during the preparation process. In color paste production, pigments, resins, and additives need to be ground. The degree of grinding directly determines the quality of the color paste; however, existing grinding machines generally do not grind sufficiently, and the grinding effect cannot be guaranteed. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a high-efficiency grinding equipment for color paste production, which performs secondary grinding on color paste raw materials to improve the fineness of the ground material and enhance the quality of the color paste.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a high-efficiency grinding equipment for pigment production, comprising a main grinding disc, a secondary grinding disc, and a grinding drive mechanism for driving the main grinding disc and the secondary grinding disc to rotate. The main grinding disc is located below the secondary grinding disc, and both the main grinding disc and the secondary grinding disc are located inside a grinding barrel. The top surface of the grinding barrel is provided with a feed pipe, and the bottom side wall of the grinding barrel is provided with a discharge pipe. The pigment raw material is first ground by the secondary grinding disc and then ground by the main grinding disc, thus performing secondary grinding on the pigment raw material, improving the fineness of the ground material, and improving the quality of the pigment.

[0005] The grinding drive mechanism includes a rotating shaft, a connecting rod, and a grinding drive motor. The grinding drive motor is fixed to the top surface of the grinding barrel, and the output shaft of the grinding drive motor is connected to the connecting rod. The connecting rod has a connecting hole, which is fitted onto the upper end of the rotating shaft. The connecting rod and the rotating shaft are circumferentially anti-rotating. The lower end of the rotating shaft is fixed to the main grinding disc. A grinding disc is provided below the main grinding disc and is fixed to the grinding barrel.

[0006] The secondary grinding disc has a sleeve at its center, which is fixed to the rotating shaft. The inner wall of the grinding barrel has a circumferential protrusion to form a grinding part. The secondary grinding disc is located at the center of the grinding part. The side wall of the secondary grinding disc is provided with grinding teeth. A grinding flow channel is formed between the secondary grinding disc and the grinding part.

[0007] Furthermore, a grinding ring is provided on the outer periphery of the main grinding disc, and the grinding ring is connected to the main grinding disc by several connecting rods. The main grinding disc, the grinding ring and the connecting rods together form a flow channel.

[0008] Furthermore, the main grinding disc is provided with several through holes that are connected at the top and bottom. Each through hole has a guide groove. The top surface of the guide groove is an inclined surface that gradually slopes upward along the direction of rotation of the main grinding disc, which facilitates the flow of pigment raw materials between the main grinding disc and the grinding disc.

[0009] Furthermore, the sleeve is fitted onto the rotating shaft, and a screw is threadedly connected to the sleeve and the rotating shaft to secure the sleeve to the rotating shaft.

[0010] Furthermore, the end of the connecting rod is a non-standard rod, and a spring is provided between the non-standard rod and the top surface of the connecting hole, so that the main grinding disc and the secondary grinding disc can be flexibly pressed down to ensure the grinding effect.

[0011] Furthermore, the grinding teeth are composed of several protrusions evenly arranged.

[0012] Furthermore, the discharge pipe is equipped with a valve.

[0013] Furthermore, it also includes a filter screen, which has an annular mounting portion that is threadedly connected to the discharge pipe to filter the ground pigment paste and facilitates the disassembly and cleaning of the filter screen.

[0014] Furthermore, a guide portion is provided above the grinding part, and the guide portion gradually tilts from top to bottom towards the center of the grinding barrel.

[0015] The beneficial effects of this utility model are at least as follows:

[0016] This utility model includes a main grinding disc, a secondary grinding disc, and a grinding drive mechanism for driving the main grinding disc and the secondary grinding disc to rotate.
