Description

Technical Field

[0001] The invention belongs to the technical field of rubber production equipment, and in particular relates to a styrene-butadiene rubber antioxidant mixing device. Background Art

[0002] During long-term storage and use, rubber and its products will gradually become sticky, hard, brittle or cracked due to the effects of heat, oxygen, ozone, variable-valence metal ions, mechanical stress, light, high-energy rays, and erosion by other chemicals and molds. This phenomenon of physical and mechanical properties decreasing over time and elasticity decreasing is called aging. As the aging process proceeds and develops, the performance of rubber and its products will gradually decrease and completely lose their use value. For this reason, it is necessary to add certain antioxidants to rubber and its products to improve its resistance to the above-mentioned various destructive effects, delay or inhibit the aging process, and thus extend the storage period and service life of rubber and its products. During the production of antioxidants, various chemical additive powder raw materials need to be stirred and mixed to obtain antioxidants. The current antioxidant mixers have the problems of poor mixing effect and low mixing efficiency.

[0003] In the prior art, a rubber antioxidant mixer with patent number CN218249593U includes: a mixing drum; a first mixer, which is arranged on the mixing drum, and the first mixer is located at both ends of the mixing drum; and a second mixer, which is arranged in the mixing drum, and the two ends of the second mixer are movably installed at the two ends of the mixing drum. The utility model provides a rubber antioxidant mixer, which, when used, adds various materials into the mixing drum from the feed inlet, at which time the gate is inserted on the discharge port, and the motor drives the stirring shaft to rotate, thereby driving the first stirring rod and the second stirring rod to rotate, and the first stirring blade and the second stirring blade stir and mix the materials, and at the same time, the stirring blades on the connecting plate cooperate with the first stirring blade and the second stirring blade, so that the materials can be quickly mixed and stirred, with good mixing effect and high mixing efficiency. After the mixing is completed, the gate is pulled out to discharge the mixed materials.

[0004] In the above device, when mixing various chemical additive powder raw materials, various raw materials are directly poured into the mixing drum without any prior processing, which leads to poor mixing effect. Moreover, after the device has mixed various chemical additive powder raw materials, it is not easy to discharge the materials. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the present invention provides a styrene-butadiene rubber antioxidant mixing device, which improves the production quality of the antioxidant by preheating various chemical additive powder raw materials, and improves the stirring efficiency of the raw materials by vibration stirring.

[0010] Optionally, a plurality of stirring rods are arranged in a ring shape in the mixing barrel, and a plurality of protrusions are fixedly arranged on the inner side surfaces of the stirring rods, and the protrusions are in contact with the inner wall of the mixing barrel.

[0011] Optionally, a rotating circle 1 rotatably arranged in a mixing barrel is fixedly arranged on the upper end of the stirring rod, and a rotating circle 2 is fixedly arranged on the lower end surface of the rotating shaft 2.

At the same time, with the rotation of the stirring rod and the vibration of the vibration motor, the antioxidant raw materials can better leave the mixing barrel. Then, when the support plate 2 descends to a certain distance, the support plate 2 is rotated by the motor 3, so that the rubber antioxidant raw materials can enter the collection frame.

[0017] Furthermore, when producing rubber antioxidants, it is necessary to mix several different types of chemical additive powders. At this time, each chemical additive powder can be placed separately in a different discharge frame 3 for preheating, which helps to improve the quality of rubber products, ensure the uniform distribution of antioxidants and other additives during the mixing process, avoid quality problems caused by excessive local concentration, and preheating can shorten the mixing time because there is no need to wait for the antioxidant to reach the working temperature, thereby improving production efficiency.

[0018] refer to Figure 6 A vibration motor 33 is fixedly arranged on the outer surface of the discharge frame 3. After the vibration motor 33 is started, the discharge frame 3 can be vibrated. The vibration of the discharge frame 3 can vibrate the additive powder inside, so that the additive powder particles can reach a higher average temperature and at the same time obtain a more uniform temperature distribution, thereby improving the production quality of the rubber antioxidant.

[0019] refer to Figure 7 The inner ends of the plurality of discharge frames 3 can be surrounded by a cylindrical empty slot, and a discharge port 312 is provided on the inner side of the discharge frame 3.

At this time, the vibration of the vibration motor 33 and the rotation of the rotating shaft 123 driven by the motor 122 can make the additive powder falling from the discharge frame 3 completely separated from the discharge frame 3. At the same time, with the rotating dispersion plate 71, the additive powder falling can be made to fall more evenly into the mixing barrel 2.
