Description

Technical Field

[0001] The utility model relates to the technical field of pigment grinding devices, in particular to a thangka mineral pigment grinding powder sieving preparation device. Background Art

[0002] Thangka mineral pigments are pigments ground from natural minerals. These mineral pigments are ground and processed to produce bright colors and are durable enough to stay on the thangka for a long time without fading. Thangka mineral pigments are often used to paint religious artworks and folk art works because their colors are rich, long-lasting, and match the material and style of the thangka.

[0003] Most of the thangka mineral pigment grinding and powder screening preparation devices in the prior art find it difficult to form pigment particles that meet the standards in one go. The pigment particles discharged after a single grinding may not meet the required standards, and the ground particles need to be manually added to the preparation box for further grinding and screening. Although the quality of the pigment particles can be improved, it is more troublesome and reduces efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a thangka mineral pigment grinding and sieving device, which can send the incompletely ground pigment particles into the preparation box for re-grinding according to needs, thereby improving the quality of the particles and solving the problems raised in the above-mentioned background technology.

[0006] As a preferred solution of the utility model, the grinding structure includes a driving motor fixedly mounted on the rear shell of the preparation box, the output shaft of the driving motor is connected to a first gear, one side of the first gear is connected to a second gear, the output ends of the first gear and the second gear are both connected to a driving shaft, and the driving shaft is located inside the preparation box and is connected to a grinding roller.

[0007] As a preferred solution of the utility model, the first gear and the second gear are meshingly connected, and the first gear is key-connected to the output shaft of the driving motor.

[0008] As a preferred solution of the utility model, the circulating suction structure includes a suction hopper located above the screen plate, the top of the suction hopper is fixedly connected to an electric lifting frame, and the telescopic end of a telescopic cylinder is connected above the electric lifting frame.

[0009] As a preferred solution of the utility model, the upper side of the suction hopper is also connected to a hose, the side of the hose away from the suction hopper is connected to a suction fan, the output end of the suction fan is connected to a circulation pipe that passes through the shell of one side of the preparation box, and the other side of the circulation pipe is connected to the interior of the feed port.

[0010] As a preferred solution of the utility model, a notch is provided inside the induction box, and the notch is used to store the electric lifting frame and the suction hopper.

[0011] As a preferred solution of the utility model, one side of the induction box is fixedly connected to a telescopic column located in the internal cavity of the preparation box shell through a connecting sleeve, and the telescopic column is a structure that can be telescoped up and down.

[0012] As a preferred solution of the utility model, vibration motors are fixedly installed at the bottom of the left and right sides of the sieve plate, and the vibration motors can drive the sieve plate to oscillate up and down.

[0013] Beneficial effect: In view of the fact that the pigment particles discharged after a single grinding in the prior art may not meet the required standards, it is necessary to manually add the ground particles to the inside of the preparation box for re-grinding and screening. Although the quality of the pigment particles can be improved, it is more troublesome and the efficiency is reduced. In the utility model, the thangka mineral pigment particles are ground by a grinding structure, and the particles are screened by the screen on the screen plate, and the particles remaining on the screen can be recovered and sent to the feed port through the circulating suction structure, and the particles are ground again by the grinding structure, thereby improving the quality of the thangka mineral pigment particles. It is very practical. BRIEF DESCRIPTION OF THE DRAWINGS
