Description

Technical Field

[0001] The utility model belongs to the technical field of mixers, and more specifically, particularly relates to a mixer for rubber raw materials. Background Art

[0002] The processing of rubber includes basic steps such as plasticizing, mixing, calendering or extrusion, molding and vulcanization, and each step has different requirements for the product. Rubber mixing is to evenly mix carbon black and various rubber additives with rubber into a rubber compound. A mixer is usually required during the mixing process.

[0003] According to the application number: CN201621473072.9, a rubber mixer is disclosed, including a stirring and mixing box, a stirring motor and a controller, the lower end of the stirring motor is provided with a rotating shaft 1, the rotating shaft 1 is provided with a plurality of stirring blades, and the left and right sides of the upper end of the stirring and mixing box are respectively provided with a feeding port 1 and a feeding port 2. The mixer is a rubber mixing equipment for mixing raw rubber and compounding agents. Under the action of the stirring motor, the stirring blades fully stir the raw rubber and compounding agents, so that the raw rubber and compounding agents are mixed more evenly before mixing. Since the stirring and mixing box is set in a shape with a large upper opening and a small lower opening, the uniformly mixed raw rubber and compounding agents are squeezed into the mixing box, which is conducive to improving the mixing efficiency. The raw rubber and compounding agent mixture entering the mixing box, under the action of the mixing motor, the two rotating shafts 2 rotate in two directions, and the mixing rollers thereon are staggered, so that the mixing effect is more obvious and helps to improve the quality of the generated rubber.

[0004] Based on the above, during the use of the existing rubber raw material mixer, when too much raw material is fed into the stirring mixing box, the resistance of the stirring blade during rotation will increase, thereby causing the stirring motor to run under load. The stirring motor is in a loaded state for a long time, which can easily cause damage to the stirring motor and cause economic losses. Utility Model Content

The utility model realizes the termination of the feeding of the feeding roller by setting the termination mechanism. When there is too much raw material in the feeding hopper and the feeding motor is under load, the stirring member will rotate relative to the stirring shaft.

The sliding of the sliding rod will squeeze the push rod through the tapered member, so that the push rod pushes the connecting rod, and the sliding rod will drive the connecting member to slide downward, so that the connecting member is separated from the connecting square rod. At this time, the feeding roller stops rotating, preventing the raw material in the feeding hopper from being too much and the feeding motor from being in a load state for a long time, thereby extending the service life and reducing economic losses. The utility model realizes the feeding of materials in the feeding hopper by setting the above-mentioned mechanism, improves work efficiency and reduces labor intensity. The utility model also realizes the termination of the feeding of the feeding roller, extends the service life and reduces economic losses. BRIEF DESCRIPTION OF THE DRAWINGS
