Automatic molding system of quartz crucible blank

Abstract

The invention discloses an automatic molding system of quartz crucible blanks. The molding system comprises a first driving device, a second driving device, a positioning device and a second transmission shaft, wherein the second driving device is installed on the first driving device through a first transmission shaft; the positioning device and the second transmission shaft are installed on the second driving device; the positioning device comprises a mold, a positioning hole and a positioning mechanism, wherein the positioning hole is arranged at the bottom of the inner wall of the mold; the positioning mechanism is used in match with the mold and the positioning hole; the positioning mechanism comprises a horizontal guide rod and a vertical rod installed at one end of the horizontal guide rod; the horizontal guide rod and the vertical rod are fixedly connected and adjusted in positions by a regulation block and a regulation nut, the end part of the vertical rod is a positioning end, the vertical rod is matched with the inner wall of the mold; the positioning end is in match with the positioning hole; a support rod is installed on the horizontal guide rod; and the bottom of the support rod is installed on the second driving device. According to the system, coaxial reversion of the positioning device can be realized both during the whole material feeding process of the quartz crucible blanks and in the period after the material is fed completely; the efficiency and the quality of the quartz sand molding are guaranteed; and the automatic molding is realized.

Description

technical field [0001] The invention relates to a quartz crucible blank forming system, in particular to an automatic quartz crucible blank forming system for automatically forming quartz sand attached to the inner surface of a crucible mould. Background technique [0002] A typical method of manufacturing a quartz crucible is called a rotary mold method, in which quartz sand is attached to the inner wall of a rotary mold, that is, the bottom surface and side surfaces of the mold, and then melted by heating with electrodes to make a quartz crucible. [0003] After the above-mentioned quartz sand is attached to the inner wall of the rotating mold, the attached quartz sand needs to be molded, that is, the quartz sand is evenly distributed along the inner wall of the rotating mold with a certain thickness. In the prior art, this operation process is often perceived by naked eyes through manual operation To achieve uniform distribution, this requires a high level of skill for th...
