The invention discloses a flushing-free device for epoxy resin glue mixing. The flushing-free device for the epoxy resin glue mixing comprises a mixing block, a runner for respectively injecting resin and a curing agent is arranged on the mixing block, and the resin and the curing agent are mixed by a static mixing pipe after being injected into the rear mixing block in proportion, and then are input to a part needing to be filled by a connecting pipeline. In order to eliminate raw material waste and environmental pollution caused by gun flushing and washing operation after epoxy resin glue mixing equipment is used, the connection and disconnection of the glue injection runner can be realized through the lifting of an anti-adhesion plunger. During filling operation, the anti-adhesion plunger rises, the runners are communicated, and the resin and the curing agent can be injected through the runners on the two sides and then enter a mixing runner to be mixed; and when the filling operation is finished, the anti-adhesion plunger descends to block the upper end of a runner III, so that a resin adhesive is prevented from entering a material mixing port to cause mixing and curing, and the descending of the anti-adhesion plunger can increase the pressure in the runner, so that adhesive liquid or the curing agent remained in the runner is discharged out of the runner.
Description
technical field [0001] The invention relates to the field of rubber mixing equipment, in particular to a flush-free device for epoxy resin mixing. Background technique [0002] The infusion resin used in the production process of wind turbine blades is a two-component glue solution. The resin infusion machine includes a mobile resin infusion vehicle and an integrated resin infusion machine. After the infusion operation is completed, a certain amount of two-component glue will remain in the mixing block and static mixing. In the tube, the residual two-component glue will solidify and block the mixing block and static mixing tube after a certain period of time. [0003] In order to avoid blockage of the mixing block and the static mixing tube, it is necessary to use a single-component glue to wash the gun after each mixing. In addition, before using the resin pouring machine next time, in order to avoid the single-component glue remaining in the mixing block and static mixing...
