[0002] Rubber products are widely used in various aspects of industry or life. During the processing of rubber products, vulcanization is often required. Due to high vulcanization requirements, there are strict requirements for the mixing and feeding of auxiliary materials. Therefore, during processing, it is necessary to premix the solid raw materials and liquid raw materials of rubber products.

[0003] After retrieval, the utility model patent with the publication number of CN211706775U discloses a rubber automatic metering and premixing device, which includes a mixing barrel, a stirring device, a solid feeding device and a liquid feeding device.

The feeding frame and the liquid feeding device are arranged on both sides of the stirring device. A solid feeding device adapted to the feeding frame is arranged in the mixing barrel. A rubber plug is plugged at the top of the feeding frame. The lower half of the mixing barrel is funnel-shaped, and the bottom end of the mixing barrel is communicated with a discharge pipe with a solenoid valve. The bottom end of the mixing barrel is also connected with a fixing device. The stirring device includes a rotating motor, a stirring shaft and stirring blades. The rotating motor is connected to the top of the barrel cover through screws. This rubber automatic metering and premixing device can not only quantitatively meter and feed liquid raw materials and solid raw materials, but also stir and mix them.
