Resin dissolving device capable of increasing dissolving rate and automatically manufacturing precoated sand

Abstract

The invention relates to the technical field of precoated sand, and discloses a resin dissolving device capable of increasing a dissolving rate and automatically manufacturing precoated sand. The resin dissolving device comprises a shell, the inner side of the shell is connected to a motor assembly, the left side of a shifting block is rotatably connected to a first connecting rod, the outer side of a first sliding rod is connected to a first rail, a first stirring rod is slidably connected to the lower side of the first sliding rod, a first solution chamber is arranged on the outer side of the first stirring rod, a first pipeline is connected between the first solution chamber and a grinding chamber, and a second stirring rod is slidably connected to the lower side of the second moving rod. According to the resin dissolving device capable of increasing the dissolving rate and automatically manufacturing the precoated sand, broken resin is driven by a stirring block to move along the inner wall of the grinding chamber, and due to the fact that a filter screen corresponding to the first pipeline is arranged on the inner wall, resin powder flows into the first solution chamber through the first pipeline, the structure achieves the effects of crushing the resin and accelerating the dissolution rate of the resin.

Description

technical field [0001] The invention relates to the technical field of coated sand, in particular to a resin dissolving device capable of accelerating the dissolution rate and automatically producing coated sand. Background technique [0002] Coated sand modeling first needs to prepare coated sand. The coated sand mainly adopts two coating processes: cold method and hot method. The cold method uses ethanol to dissolve the resin, and adds urotropine during the sand mixing process The two are coated on the surface of the sand grains and then the ethanol is volatilized to obtain the coated sand. [0003] At present, most of the resins on the market are dissolved in ethanol, mainly by adding resin particles into ethanol and then manually stirring them to dissolve. Among them, the resin particles are relatively large, which makes their dissolution rate low, and there is still a need Manual stirring consumes a lot of manpower, and the lack of automation makes its work efficiency ...
