Description

Technical Field

[0001] The utility model relates to the technical field of resin processing, in particular to a stirring device for unsaturated resin. Background Art

[0002] Unsaturated resin refers to a polymer compound containing unsaturated double bonds generated by the polycondensation reaction of dibasic acid and diol. The earliest resin discovered by humans was a grease-like substance extracted from tree secretions, such as rosin, which is why there is a "tree" before "resin".

[0003] When unsaturated resin is used in the production of different products, different additives need to be added, so a stirring device is needed for stirring. Unsaturated resin at room temperature is usually in a fluid state, and the usual stirring method is to stir it with a stirring paddle, and it is a continuous stirring. When the stirring paddle continues to rotate in the fluid unsaturated resin, it will gradually drive the unsaturated resin to follow the flow. After the unsaturated resin produces a synchronous flow, the relative movement between the various parts is reduced, so the stirring efficiency will be reduced, and a vortex will be formed in the center of the stirring, which reduces the contact between the unsaturated resin and the stirring paddle, further reducing the stirring efficiency.

[0021] The reciprocating mechanism drives the rotating rod 5 to rotate back and forth, thereby driving the stirring mechanism to rotate back and forth. After the stirring mechanism rotates in one direction for stirring, the unsaturated resin flows in that direction, and then the stirring mechanism rotates in the opposite direction, so that the rotation direction of the stirring mechanism is opposite to the flow direction of the unsaturated resin, thereby generating a violent collision and improving the stirring efficiency. In addition, the stirring mechanism reciprocates and will not generate a vortex in the center of stirring, thereby enabling the unsaturated resin to obtain maximum contact with the stirring mechanism for stirring.
