Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a rubber additive mixer. Background Art

[0002] Rubber additives refer to additives needed in the process of processing natural rubber or synthetic rubber into rubber products. They are indispensable raw materials for improving the quality of rubber products. Rubber additives are important auxiliary raw materials in the rubber industry. Rubber additives can improve the performance of rubber and make rubber more applicable. Among them, rubber additives need to mix multiple raw materials together and stir them during the production process, so a mixer is needed to complete the stirring and mixing operations.

[0003] When the current rubber additive mixer is stirring rubber additives, the raw materials close to the side wall of the stirring barrel may not be able to completely contact the stirring shaft, which may cause uneven stirring. If a longer stirring rod is set, there will be greater resistance, and high-speed stirring may not be achieved, which may affect the stirring efficiency of the rubber additive. Utility Model Content

[0007] Preferably, a top cover is threadedly connected to the mixing barrel, a motor is fixedly connected to the top cover, an output end of the motor is fixedly connected to a rotating shaft, and a feeding port is provided on the top cover.

[0008] Furthermore, a hemispherical portion is provided at the lower side of the mixing barrel, a discharge port is provided at the lower side of the hemispherical portion, and a sealing column is threadedly connected to the discharge port.

[0009] In order to improve the stirring efficiency, preferably, the stirring assembly includes a plurality of stirring rods equidistantly fixed on the rotating shaft, and the stirring rods are provided with triangular grooves.

[0010] In order to facilitate material discharge, preferably, a scraper matching the hemispherical portion is fixedly connected to the bottom of the rotating shaft, and the scraper is arranged at an angle.

[0011] In order to facilitate the rapid flow of raw materials, further, an inclined surface is provided on the material guide plate.

[0012] Compared with the prior art, the utility model provides a rubber additive mixer, which has the following beneficial effects:

[0013] 1. The rubber additive mixer, the rotating shaft drives the fitting track to rotate rapidly in the mixing barrel through the connecting rod. The raw materials close to the side wall of the mixing barrel move upward along the fitting track under the action of inertia, and finally fall onto the guide plate through the square groove, and then stay at the mixing component through the guide plate, thereby effectively preventing the raw materials attached or stuck to the side wall of the mixing barrel from contacting the mixing shaft for mixing, thereby effectively improving the mixing effect and mixing efficiency of the rubber additive raw materials.

[0014] 2. The rubber additive mixer drives the stirring rod to rotate through the rotating shaft to stir the raw materials in the stirring barrel, and by providing a triangular groove, when the stirring rod moves, the raw materials in the stirring barrel flow back to the rear side of the triangular groove, which can effectively improve the stirring effect of the rubber additive raw materials.

[0015] 3. The rubber additive mixer controls the motor to reverse first, so that the raw materials attached to the side wall of the mixing barrel flow downward, and finally controls the motor to rotate forward, so that the raw materials are discharged from the discharge port through the scraper, thereby effectively preventing the waste of raw materials.

[0016] The parts not involved in the device are the same as the prior art or can be implemented by the prior art. The utility model effectively prevents the raw materials attached or stuck to the side wall of the mixing barrel from contacting the mixing shaft for mixing, thereby effectively improving the mixing effect and mixing efficiency of the rubber additive raw materials and effectively preventing the waste of raw materials.
