Description

A spiral mixer

technical field

The utility model relates to a material mixing device, in particular to a spiral rubber mixing machine.

Background technique

The rubber mixer is a mechanical device that stirs two or more colloidal fluids through the spiral blade for multiple times, and then fully mixes them evenly. However, it is not suitable for substances such as colloidal fluids that solidify quickly after mixing.

At present, the traditional rubber mixing machine is usually composed of gear transmission, and there is a serious glue leakage problem, which not only causes waste, increases the cost of the product, but also may cause damage to parts. The document with the application number 201020259847.9 discloses a rubber mixing machine consisting of an input device and a rubber mixing device. It mainly uses a planetary gear pump as a rubber delivery pump. It does not require couplings and adapters. It has a compact structure and a high load-carrying capacity. Higher than the helical gear, so the transmission is stable. However, this design is lacking in uniform mixing. This scheme only stirs the colloid by the protrusion on the upper side of the disc, and only stirs in the horizontal direction. The stirring is not thorough enough, resulting in uneven mixing of two or more glues. , not up to production standards.

1) Through the mutual cooperation of the feeding screw mixing barrel, horizontal screw agitator, discharging screw mixing barrel and transport stirring shaft in the working process, four continuous mixing processes are realized. Omnidirectional stirring in all directions is realized through the arrangement of the feeding spiral mixing barrel, horizontal spiral stirring barrel, discharging spiral stirring barrel and transport stirring shaft, which makes the stirring more uniform and the mixing degree is high.

2) The colloidal fluid is stirred by spiral blades, so that the degree of mixing between the colloidal fluids is high.

3) The transport stirring shaft can stir the colloid transported from the discharge spiral mixing barrel, and at the same time, the colloid is slowly transported to the output device under the directional rotation of the spiral blade, so that the material can be transported while stirring, which saves the transportation cost of the material and The processing cost is low, the space is saved, the overall structure is compact and simple, and the assembly is convenient.

4) The use of bevel gears has long service life, high load bearing capacity and strong chemical and corrosion resistance. It can also reduce noise and shock, and has low cost. It can also realize the transmission of two vertical axes and has good transmission performance.

5) The overall structure of the rubber mixing machine is compact, which reduces the leakage of materials. During the transmission process, the raw material directly enters the feeding screw mixing barrel from the feeding port, and the time of direct contact with the air is less, which is beneficial to the protection of the colloid performance, and the mixing process does not need to be transported through pipelines, which reduces the working space and Working hours are conducive to the smooth progress of the entire work process.

6) It is a continuous stirring process from the colloid entering the feeding port until the final colloid is output from the output device, which makes the mixing of the colloid more uniform and sufficient.

7) Only one power source is used in the four stirring processes, effectively reducing the number of power sources.
