Description

Technical Field

[0001] This utility model relates to the field of rubber mixing technology, and more specifically, to a mixing device for producing rubber plasticizers. Background Technology

[0002] Rubber plasticizers are substances used to increase the softness, flexibility, extensibility, and elasticity of rubber. Depending on the application, various modifiers are added to plasticizers. When adding multiple modifiers in a mixing device for plasticizer production, the weight of each modifier must be weighed first, and then they are sequentially fed into the tank for mixing. For example, patent CN220513897U discloses a mixing device for rubber plasticizer production. In the plasticizer production process, various raw materials need to be added and mixed according to a certain proportion. The feed pipes of multiple feeding cylinders are connected to raw material tanks that provide various raw materials. Each feeding cylinder is weighed individually and then fed into the tank, where the desired plasticizer is obtained through stirring. Each feeding cylinder is connected to a weighing platform. After the raw materials are weighed according to different quantities, they are quickly fed into the tank through the first discharge pipe under the action of the extrusion component, preventing raw material residue in the feeding cylinders and thus avoiding a decrease in the production quality of the plasticizer, achieving precise quantitative feeding.

[0003] When the above-mentioned device is in use, the driving component drives the swing rod to swing back and forth, causing the rack to move horizontally back and forth. The meshing of the gear and rack causes the stirring shaft to rotate back and forth. Multiple sets of stirring blades and multiple sets of spiral blades thoroughly mix the raw materials. However, the tank is prone to vibration during operation. The vibration of the tank will be transmitted to the upper material cylinder through the discharge pipe, which will affect the accuracy of the weighing of the upper material cylinder and make it inaccurate to mix different types of raw materials.

[0009] In a preferred embodiment, the output shaft of the servo motor passes through the end face of the mixing tank and extends into its interior, and the output shaft of the servo motor has a rotating rod inside the mixing tank.

[0010] In a preferred embodiment, the outer end face of the rotating rod is provided with stirring blades, and the upper side of the outer end face of the feed tube is provided with a feed solenoid valve.

[0012] In a preferred embodiment, the discharge solenoid valve, servo motor, weighing sensor, electric telescopic rod, and guide solenoid valve are all electrically connected to external control equipment.
