Description

Technical Field

[0001] The utility model belongs to the technical field of grinding devices, in particular to a pigment grinding device. Background Art

[0002] Oil paint is a special painting pigment for oil painting, which is made by mixing and grinding pigment powder with oil and glue. Most of them are sold in tubes on the market, but they can also be made at home. The basic components of oil paint are the same as other painting pigments, including colorants, body pigments, color carriers and certain auxiliary materials such as plasticizers, stabilizers, retarders or drying agents. The pigments used for painting can be purchased as finished products or ground by yourself. The purchased materials have uniform particle size. For the need for multi-level color display, pigments with a large particle size range are generally ground manually using stone mortars and mortars. The manual grinding method takes a long time and is relatively labor-intensive. When grinding oil paint, it is necessary to avoid high-temperature oxidation of color carriers and certain auxiliary materials. For this purpose, this application document provides a pigment grinding device. Utility Model Content

The rolling table comprises two electric support single rollers 1 arranged symmetrically in parallel and a connection adjustment component 4 for connecting and adjusting the distance between the two electric support single rollers 1. The grinding jar 2 is placed on the roller 13 of the two electric support single rollers 1. Two anti-deviation devices 5 for guiding the two ends of the grinding jar 2 are installed on one of the electric support single rollers 1. Among them, a protective cover 6 is installed at the open end of the grinding jar 2. The protective cover 6 comprises a circular cover body 61. A conical cylinder 62 with an inwardly contracted opening is arranged at the center of the circular cover body 61. The speed regulator 3 synchronously controls the rotation speed of the two electric support single rollers 1, and the adjustment component 4 adjusts the distance between the two electric support single rollers 1. The grinding jar 2 preferably uses a ceramic jar body with a thick wall. While the protective cover 6 ensures heat dissipation, the conical cylinder 62 at the center position effectively prevents the pigment from splashing during the grinding process.

[0028] When in use, color powder, body pigment, color carrier and auxiliary materials are poured into the grinding jar 2, and then covered with the protective cover 6. Then the grinding jar 2 is placed horizontally on the two rollers 13 of the rolling table, and the two anti-bias devices 5 are moved to be placed at the bottom of the grinding jar 2 and the end of the protective cover 6, and then the anti-bias devices 5 are positioned. The rotation of the two electric support single rollers 1 is synchronously controlled by the speed regulator 3 to drive the grinding jar 2 to rotate smoothly. During the rotation of the grinding jar 2, the grinding balls in the grinding jar 2 continuously impact and refine the pigment mixture. According to the particle size distribution requirements of the painting pigment, the speed regulator 3 is started and stopped in stages to remove the grinding jar 2 to sample and observe the ground pigment until the grinding is completed.

[0029] The electric support single roller 1 includes a base plate 11 and a brushless motor 12. Two roller frames 14 are fixed on the upper surface of the base plate 11.

The connection adjustment component 4 includes a stud 42 and a plurality of cylindrical guide rods 41. The center of the stud 42 is set as a hexagonal prism 421. A plurality of guide circular holes 17 cooperating with the cylindrical guide rods 41 are symmetrically provided on the opposite sides of the two base plates 11 of the two electric support single rollers 1. A first threaded hole 18 threadedly connected to one end of the stud 42 is provided on the base plate 11 of one of the electric support single rollers 1. A second threaded hole threadedly connected to the other end of the stud 42 is provided on the base plate 11 of the other electric support single roller 1. The two electric support single rollers 1 can be pulled closer or pushed away by clamping the hexagonal prism 421 at the center position of the stud 42 with a wrench. A number of cylindrical guide rods 41 play a role in the smooth movement of the two electric support single rollers 1.

[0030] The anti-deviation device 5 includes a movable seat 51 slidably mounted on two fixed rods 16. Two top screws 52 are connected to the movable seat 51 through a thread. A round tube 53 arranged obliquely is fixed to the upper end of the movable seat 51. A step shaft rod 54 is slidably fitted in the round tube 53. A bolt 55 with a handle for fixing the step shaft rod 54 is connected to the outer wall of the round tube 53 through a thread. A bearing 56 is installed at the end of the step shaft rod 54. The position of the anti-deviation device 5 on the two fixed rods 16 can be adjusted and fixed flexibly, and the bearing 56 at the end of the step shaft rod 54 is in safe and effective limited rolling contact with the grinding jar 2, and the overall operation is convenient and reliable.
