Description

Technical Field

[0001] This utility model relates to the technical field of rubber mixing, and in particular to a rubber mixing device with a graded mixing function. Background Technology

[0002] The graded mixing function of the rubber internal mixer is an advanced mechanical device that can improve the quality and efficiency of rubber production. During the raw material transport, multiple raw materials are transported from the transport point to the corresponding mixing point, and the raw materials are mixed through the effect of stirring and temperature control.

[0003] Existing rubber mixing devices, such as the rubber mixing device with graded mixing function disclosed in utility model patent application number 202322425797.7, mainly include a rubber mixing section for mixing rubber raw materials, a first transmission section for conveying rubber raw materials, a second transmission section for conveying rubber raw materials, a transmission section, and a horizontal push section for pushing the raw materials. The first transmission section includes a first transmission screw and a first transmission pipe. In use, the pipe for conveying raw materials and the transfer pipe are connected, and then the raw materials are conveyed into the temporary storage box. The rotary drive section is started, and the rotary drive section drives the first and second transmission wheels to rotate. The first and second transmission wheels drive the first and second transmission screws to rotate, so that the telescopic drive section drives the push plate to gradually push the raw materials into the second and first transmission pipes, and then convey them into the rubber mixing section through the first and second transmission screws.

[0004] However, most existing mixing equipment only has one stirring device to mix the materials, resulting in poor mixing effect. Moreover, it usually requires multiple storage tanks to feed different auxiliary materials, which is very troublesome to use. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a rubber mixing device with a graded mixing function that not only mixes the auxiliary materials through two stirrings and ultrasonic vibration to ensure the mixing effect of rubber, but also allows different types of auxiliary materials to be fed in batches, eliminating the need for multiple sets of storage tanks.
