[0001] The utility model relates to the field of stirring devices, in particular to a polyester resin stirring device. Background Art

[0002] Ester resin is a general term for polymer compounds formed by the condensation of diols or dibasic acids or polyols and polyacids. Polyester resins are divided into saturated polyester resins and unsaturated polyester resins. Unsaturated polyester adhesives are mainly composed of unsaturated polyester resins, pigments, fillers, initiators and other additives. When the polyester resin is made, stirring equipment is required to fully stir and mix the raw materials for the next step of preparation.

Through the setting of the transmission belt, the second rotating wheel can rotate simultaneously with the first rotating wheel, and then the rotation of the second rotating wheel drives the screw to rotate. At the same time, through the setting of the thread groove, the slide groove and the limit rod, the threaded barrel can move up and down. At this time, the transmission motor is started to rotate it, and then the rotation of the transmission motor drives the rotating shaft to rotate. Through the rotation of the rotating shaft, the stirring plate is driven to rotate. Finally, the stirring plate is stirred by its own rotation. At the same time, with the operation of the drive motor, the stirring plate can rotate and move up and down at the same time, thereby maximizing the stirring effect.

[0004] However, since the polyester resin has a certain viscosity, it is easy for the polyester resin to stick to the inner wall of the mixing tank during and after the mixing. When the polyester resin is discharged, the discharge pipe needs to be opened to allow the polyester resin to be discharged through the discharge pipe. During this process, the polyester resin is easy to stick to the inner wall of the discharge pipe, causing the discharge pipe to be blocked and affecting the discharge of the polyester resin.

[0005] Therefore, it is necessary to invent a polyester resin stirring device. Utility Model Content
